A mechanical joint for an accumulator-internal heat exchanger (AccuIHE) module is provided. The mechanical joint includes a heat exchanger pipe and a cover plate having an internal connecting area. The internal connecting area is adapted to receive the heat exchanger pipe. The cover plate further has an external connecting area in fluid communication with the internal connecting area, the external connecting area adapted to receive a high-pressure coolant line. The mechanical joint also has a housing adapted to receive the cover plate and the heat exchanger pipe, and a sealing element. The sealing element is disposed between the heat exchanger pipe and the internal connecting area of the cover plate. The sealing element facilitates a substantially fluid tight seal therebetween. An AccuIHE module having the mechanical joint and a method for forming the mechanical joint are also provided.

The invention relates to a punching press with a clamping plate (27) and with a press ram (1) which lies opposite the upper side of the clamping plate (27) and operates towards the clamping plate (27) and is moveable up and down via four tension columns (2) by means of a crank drive arranged below the belt movement plane (X) of the punching press. The press ram (1) is guided exclusively via the tension columns (2) which, in turn, are guided in inclination-tolerant guides (3) in the belt movement plane (X) in such a manner that the press ram (1) and the tension columns (2) can be positioned obliquely as a consequence of differing longitudinal expansion of the tension columns (2) under an eccentric load by the tension columns (2) being inclined about axes of inclination running in the region of the belt movement plane (X) of the punching press. By means of the configuration according to the invention, distortion of the punching press under an eccentric load, which would lead to uncontrollable operating conditions during the punching and a high degree of wear at the guides of the machine, is avoided, and it can be ensured that, in the event of a possible skewed position of the ram, no tool offset, which would result in a high degree of tool wear or even in tool fracture, occurs.

The invention discloses a method for planting pollution-free selenium-rich lettuce. The method includes: pre-treating soil : accelerating germination and raising seedlings, preparing an ozone solution, adding 2 mass %-3 mass% glass powder into the ozone solution and evenly stirring the ozone solution to acquire a soaking solution, soaking seeds, and performing germination accelerating and sowing; performing planting; performing water and fertilizer management: irrigating the lettuce with seedling-reviving water after the lettuce is planted for 3-5 days, dissolving 8-10 Kg of a mixed fertilizer and 0.8-1 Kg of the selenium-rich nutritive solution in 150 Kg water in 10-15 days to water roots of the lettuce in one mu land, dissolving 10-12 Kg of the mixed fertilizer and 1-1.2 Kg of the selenium-rich nutritive solution in 200 Kg water to water the roots of the lettuce in one mu land during a rosette stage of the lettuce, and irrigating the lettuce with water and fertilizer according to the amount of water and fertilizer of the rosette stage again when heart leaves of the lettuce curve inward; arranging a reflective curtain outside a greenhouse; and disease and pest control. The method can effectively increase the selenium content of the lettuce, improve the nutriment quality of the lettuce, and increase the income of farmers.

An active catheter design incorporating a distal loop coil that is electrically connected to an ultrasonic transducer having a comparable profile. The ultrasonic transducer induces ultrasonic waves at the Larmor frequency at the distal end of a dielectric optical fiber that runs along the active catheter shaft. The optical fiber serves as the transmission line instead of a convention conductor, eliminating the RF induced heating. The dynamic strain generated by the ultrasonic transducer can be measured using optical interferometry by coupling a laser at the proximal end of the optical fiber using the acousto-optical effect. A fiber embedded Bragg reflector grating, for example, can be used for this purpose. The device can also be used for simultaneous temperature measurements among other parameters.

The invention belongs to the technical field of communication and positioning, and discloses a low-orbit satellite real-time precision orbit determination method and system, and the method comprises the steps that a ground monitoring station obtains the basic navigation positioning information of the ground monitoring station through collecting the basic navigation positioning information of a satellite navigation system, and transmits the basic navigation positioning information to a ground master control station; the ground master control station generates satellite navigation system differential correction information according to the physical position information of the ground master control station and the basic navigation positioning information of the ground monitoring station, andsends the satellite navigation system differential correction information to an uplink injection station; the uplink injection station sends the differential correction information of the satellite navigation system to a Beidou-3 satellite; the Beidou-3 satellite broadcasts satellite navigation system differential correction information by using a short message communication function; and after receiving the satellite navigation system differential correction information, the low-orbit satellite performs real-time precise orbit determination in combination with the low-orbit satellite basic navigation positioning information received by the satellite-borne receiver of the low-orbit satellite. The method and the system have the advantages that the method and the system do not depend on an external communication link, are completely independent and are high in safety and cost performance.

The present invention is directed to an air blower unit for inflating an air permeable body. The air permeable body has an inlet sleeve with a distal end and a light unit located within the body. The air blower unit comprises an exhaust port engageable with the distal end of the inlet sleeve for delivering air to the body thru the inlet sleeve. The air blower unit further comprises an electrical cord passing into and out of the exhaust port and thru the inlet sleeve of the body for connection with a light unit. The air blower unit may further comprise a protective cover to enclose the electrical cord as it passes into and within the exhaust port.

A method for manufacturing a multilayer hose having reduced permeation of hydrocarbon fuel vapor, wherein the multilayer hose is useful as a hydrocarbon fuel transport hose, comprises the steps of: extruding a first fluoroelastomeric tubular structure having an inner surface and an outer surface; applying an adhesive on the outer surface of the first fluoroelastomeric tubular structure, wherein the adhesive is applied to the outer surface of the first fluoroelastomeric tubular structure using piezo electric technology comprising a piezo element disposed in an adhesive reservoir positioned at an exit end of an extruder for extruding the first fluoroelastomeric tubular structure. The adhesive reservoir comprising a plurality of nozzles equally spaced apart around the exit end of the extruder through which adhesive is discharged onto the surface of the first fluoroelastomeric tubular structure in a precise and uniform manner as the first fluoroelastomeric tubular structure exits the end of the extruder, the discharge of the adhesive being activated by application of an electric current applied to the piezo element causing the piezo element to rapidly oscillate in a precise and uniform manner causing the adhesive to be repeatedly discharged through the plurality of nozzles in a pulsating manner, whereby the adhesive is uniformly applied to the outer surface of the first fluoroelastomeric tubular structure; and extruding a second fluoroplastic tubular structure onto the first fluoroelastomeric tubular structure such that the adhesive is disposed between the first fluoroelastomeric tubular structure and the second fluoroplastic tubular structure.

A solar-powered attachable light is adapted for use as a holiday decoration and includes a lamp pivotably mounted to an enclosure. A solar cell charges an internal rechargeable battery during daytime hours and the rechargeable battery powers the lamp during nighttime hours. A rear of the enclosure includes a clip assembly for removable attachment of the device to various outdoor structures. The device eliminates the presence of wires and the requirement of connection to a fixed power source in a manner particularly beneficial when simultaneously arranging decorative outdoor lighting in a variety of locations.
