A cyclonic separating apparatus for separating particles from a dirt-laden airflow includes a cyclone for separating and collecting dirt and dust from the dirt-laden airflow. The cyclone has an air inlet, an air outlet, a longitudinal axis and a wall. The wall includes a first portion and a second portion spaced farther from the longitudinal axis than the first portion, the first and second portions being spaced along the longitudinal axis. The cyclone also includes at least one lip extending from the first portion of the wall into a portion of the cyclone surrounded by the second portion of the wall. By providing a cyclone with a wall having two portions of different sizes and a lip extending from the portion with the smaller size into the portion with the larger size, the risk of blockages due to re-entrainment and movement of dirt and dust within the cyclonic separating apparatus is reduced.

A strap adjuster has a quadrangular frame; a plurality of slots defined in the frame to extend in a transverse direction such that a strap can be fitted through the slots; and at least one support bar formed between the slots, wherein recessions are formed on both widthwise side surfaces, respectively, of the frame such that the frame can be easily grasped using fingers.

An operator cab for heavy equipment is disclosed to prevent a sliding door mounted on the cab from rocking or rattling in X, Y, and Z-axis directions due to a shock or vibration applied to the cab in a state that the sliding door is fully opened or closed. The operator cab includes an outer sidewall having a doorway formed thereon; upper and lower rails provided on upper and lower portions of the outer sidewall; a sliding door being slid by upper and lower rollers engaged with the upper and lower rails; an upper stopper of an opened position, installed in the opened position of the outer sidewall, for being in contact with the upper roller when the sliding door is fully opened, to prevent the sliding door from rocking when the upper stopper becomes in contact with the upper roller; and a lower stopper of an opened position, installed in the opened position of the outer sidewall, for being in contact with the lower roller when the sliding door is fully opened, to prevent the sliding door from rocking when the lower stopper becomes in contact with the lower roller.

A surgical bone screw 1) and driver (31), and a method for using them for repairing an osteotomy or fracture. The screw has a shaft having a head (5) at its proximal end, screw threads (3) at its distal end and a compression member (7) between the head and the screw threads. In an embodiment, the threads are self-tapping and self-drilling, the head is polygonal, and the sides of the polygon are convex. The driver turns the screw until the threads cross a fracture site and the compression member contacts the proximal bone fragment. The threads and compression member draw the fragments together and leaves the head entirely clear of the bone surface. The screw is removed through a small incision. Tilting the driver to allow the socket to engage an inwardly extending lower portion of the head permits the driver to lift the screw out of the bone.

A web dispenser comprising a housing for holding at least one roll of web material therein. A mandrel connects to the housing for maintaining at least one roll of web material thereon and facilitating the rotation of the roll of web material to dispense the web material from the roll. A mounting block is affixed to the housing for mounting the housing to a wall at an acute angle relative to the wall. This results in the ergonomic presentation of web material to a stationary user.

The invention relates to an emergency light device for marine use comprising a housing accommodating an electronic circuit, a least one transparent dome, and a first and a second shell member, said electronic circuit comprising at least one light emitting diode provided in the at least one transparent dome, an electrical power supply comprising at least one battery of the AA, AAA or AAAA type, and at least one operating switch, said emergency light characterized in that the housing has a width which is substantially larger than the height, preferably the width is at least double or triple the height.

An improved railroad coupler mount for attaching equipment, such as an end-of-train device (EOT), marker light, test gear, etc., to a railroad coupler. The mount is comprised of a pivoting lever with brace (a V- or U-shaped notch) that grips the rib between vertically spaced coupler coring holes and a lever tip that contacts the inner wall of the coupler top coring hole, a pad that bears against the exterior face of the coupler guard arm side and a mechanism that forcibly pivots the lever tip towards the pad on an axis roughly parallel to the coupler axis.

In a vehicle windshield wiper system, a support base includes a connecting rod (9) fixedly attached to a vehicle body and extending across a width of the vehicle body, and a base member (10, 11) depending from an intermediate part of the connecting member. A wiper motor (2) attached to a lower surface of a horizontal wall portion (11) of the base member, and a crank arm (3) is attached to an output shaft of the wiper motor. The base member is formed with an opening (13) to avoid an interference with the crank arm as the crank arm undergoes the rotative movement. The opening in the support base prevents an interference with the movement of the crank arm, and this allows the crank arm and an associated link mechanism (6) to be placed opposite to a vertically intermediate part of the support base, and immediately adjacent to the support base. Therefore, the windshield wiper system can be accommodated in a readily available space (24) under the lower edge of the windshield.

An intravascular device for keeping open a previously constricted site within a vessel and for minimizing tissue debris at such a site from closing off the vessel is provided. The device includes an expandable substantially tubular body having a distal end and a proximal end. The device also includes a flexible netting system that is circumferentially disposed about the body, and extends beyond at least one of the distal end or proximal end. The netting system can expand along with the body to minimize release of tissues debris at the site from closing the lumen of the vessel. The netting system can include a plurality of pores to permit communication between fluid flow within the vessel and the vessel wall, and at least one pharmacotherapeutic agent for the treatment or prevention of certain conditions. A method for placing the device at a site of interest is also provided.

The present invention provides a hand-held, noninvasive diagnostic device for measuring the electric fields in mammalian skin and other epithelial structures. The device includes an outer housing that contacts the skin, providing stability and allowing the device to move along with minor movement of the skin. Recessed within the outer housing is a probe that acts as a sensor to measure the electric field in the skin through an aperture in the bottom surface of the outer housing. By applying a series of known voltages while the probe is vibrating, the skin's local surface potential can be measured and the lateral electric field can be calculated from the spatial distribution of surface potential measurements. Active feedback is used to maintain a constant distance between the probe and the skin surface.

Provided is a vehicle front body structure comprising a port device (30) received in a housing (36) and mounted to a vehicle body under a front hood (7). A lid (58) is provided on the housing to selectively close a port opening (21) in the front hood, the lid being provided with a lid plate (59) that selectively closes the port opening, and a hinge arm (61) extending from the lid plate into the housing and rotatably connected to the housing via a hinge shaft (75) extending laterally.

A nibbler assembly includes a punch and a die. The die includes a through opening formed therein, which opening has an oblong configuration as viewed along a vertical direction. The die includes an upper surface including a recess extending from an upper peripheral portion of the through opening at an upstream side of a feed direction towards the upstream of the feed direction. The recess is dented downwardly relative to other portions of the upper surface. The punch includes a blade substantially matching in shape with the through opening. The blade includes an upstream end portion in the feed direction provided with opposite corners each having an arcuate shape as viewed along the vertical direction. The punch and the die are operable to punch successive holes that at least partially overlap along the feed direction so as to form an elongated hole in a sheet material.
