An electronic control unit (an ECU) detects an operating condition of an engine and quantity of particulate matters accumulated in a diesel particulate filter (a DPF) having an oxidation catalyst from a pressure difference across the DPF. The ECU operates temperature increasing means for regenerating the DPF based on the above detection results. During a low speed and light load operation, the ECU does not perform temperature increasing operation similar to an operation performed during a middle load operation. Instead, the ECU performs operation such as reduction of recirculated exhaust gas quantity in order to inhibit an increase in the quantity of the accumulated particulate matters. When the operating condition is changed afterward, the temperature increasing means is operated, so safe regeneration of the DPF is achieved.

A footwear cover arranged to receive footwear article therein comprises a sole portion, a toe portion and a heel portion. Each of the toe and heel portions comprises a vertical wall portion in which the toe portion further comprises an upper resilient portion extending inwardly to receive the toe of the footwear article thereunder and the heel portion further comprises a plurality of horizontal ridges extending inwardly to engage the heel of the footwear article. The ridges terminate at respective inner free edges lying in a generally common vertical plane.

An adapter cap is configured to convert a plastic water or drinking bottle into a nasal washing device. The cap has a connector portion or mechanism configured for engagement with the neck of a plastic water bottle in place of a conventional bottle cap, and a tapered applicator or spout portion having a tip with an opening which is configured for placing into a nostril of a user during a nasal washing procedure.

A machine room (15) is provided between a cab (14) and a counterweight (6) which are mounted on a revolving frame (5) to accommodate an engine (7). The machine room (15) is built of a left front support member (20), a rear support member (21), a connecting support member (22) and a left side housing door (25). A horizontal grip portion (22B) and an inclined grip portion (22C) are provided in intermediate portions of the connecting support member (22) which connects the left front support member (20) and the rear support member (21). By opening the left side housing door (25), the inclined grip portion (22C) of the connecting support member (22) comes out, permitting a servicing worker to hold on thereto helping him or her perform a cleaning job of a rear face portion (14B) of a cab (14) in an efficient manner.

An upward facing probing mechanism using mercury probe contacts for accurate automatic multi-site measurements of a semiconductor wafer, especially of ultra-shallow ion implanted layers on a semiconductor wafer held top surface facing downward. A fixed force is applied to the wafer regardless of the thickness of the wafer through the of use of a regulated pressure piston. Incorporated are a plurality of spring-loaded rod assemblies to support the floating probe head to position the probe head face into full contact with the wafer surface accurately placing all mercury contacts on the surface of the wafer regardless of the inclination of the wafer as a result of the even support of the probe head by the spring-loaded rod assemblies. Included is a mechanism to refresh the mercury contacts for each probing with full containment and recovery of the mercury used in each probing.

A method and apparatus for selective removal of heavy ions, biological, cations, anions or other elements of interest from liquids using magnetic nanoparticles, and recovery of nanoparticles to be reused in the wastewater purification. For certain embodiments, after water treatment and magnetic separation, the loaded nanoparticles may be washed, regenerated, collected and re-introduced in the water treatment cycle. Water treatment and particle regeneration take place singly or simultaneously. In another disclosed embodiment of the process, the electricity consumed by the pumping system is supplied by renewable energy sources such as solar, wind, geothermal, biogas or small hydro.

An improved testing device for testing a drainage or plumbing system for vertical piping is provided which allows the tester to determine which particular floor is being currently checked for leaks at any time during the test. The testing device includes a tee disposed in fluid tight series communication between a drainage system and drain. A controller means is included which utilizes a ball valve to prevent water spillage during removal of the testing device when testing the drainage system for leaks. A ball valve actuator facilitates actuation of the ball valve. A closure plug assembly is provided which includes multiple ports adapted to accommodate a valve stem of the controller means and a fillgauge apparatus. A fluid elevation gauge provides tester with a visual readout of water elevational levels. A lightweight container is provided to store the testing device to facilitate transportability.

Sealable feces disposal bags are provided in a temporary storage system. The bags are used to collect animal feces. After feces collection, the bags are temporarily sealed and then taken to a waste storage receptacle. The receptacle houses a bag heat sealer, mechanical sealer, or adhesive sealer which is used to provide an odor-free seal to the bag. Sealed bags are stored on the receptacle until they are removed for garbage pick-up.

An electric ear cleaner for removing the earwax from antrum auria is composed of a shell consisting of front, back and lower shells, the battery in the lower shell, the fan in the back shell, and the motor and engaged a pair of gears in the front shell which has also a wind tube and a flexible sucking tube in serted in the front end of said wind tube.

A beverage preparation machine (1) has: a housing (5); a duct (10) with an outlet (15); a conduit (20) upstream the duct and connected thereto; and a waste liquid collector (30) arranged to collect waste liquid from the outlet. The duct has: an operative position for circulating beverage through the conduit and dispensing said beverage from the outlet outside the housing above a user-receptacle filling area (35); and a cleaning position for circulating cleaning fluid through the conduit and evacuating said cleaning fluid from the outlet inside the housing to the waste liquid collector. The duct is pivotally assembled about a pivoting axis (11) to the conduit for pivoting the outlet between the operative position and the cleaning position.

Compositions and methods for cleaning surgical devices employing one or more phosphonates, one or more surfactants and one or more buffering agents in amounts effective to reduce elemental deposits on surgical devices are disclosed. Additionally, methods of making and using surgical device cleaning solutions containing one or more of the subject compositions are also disclosed.

The invention provides a network risk monitoring system of a transformer substation. The system comprises a collection monitoring module used for collecting monitoring data in real time, a security analysis perception module used for performing transformer substation network security risk perception and comprehensive analysis on the collected monitoring data and further evaluating threat degrees of different network security events which the transformer substation network is faced with, a defending and alarming module used for realizing graded early warning and active defense for different network security risks based on the evaluation result of the security analysis perception module. The network risk monitoring system of the transformer substation is used for monitoring the transformer substation network in real time, analyzing threat degrees of different network security events to the transformer substation network rapidly and making out a response rapidly, realizes graded early warning and active defense for different network security events in the transformer substation network, removes security hazards in time and guarantees that the transformer substation has a secure and clean network environment.

An improved shower or plumbing sanitizing system is provided by a showerhead adapter and/or tap port configured to mount between a water supply stub and an outlet such as a showerhead, hose or faucet and which delivers and imparts a cleansing or sanitizing agent, particularly liquid sanitizer, to the plumbing components prone to infestation with opportunistic bacteria.
