Abstract: An apparatus for ionizing air to remove particulate matter. The apparatus comprising an ionizer and a bracket for mounting the ionizer in a duct or enclosure. The ionizer includes a series of electrodes which span a portion of the duct. The electrodes are energized by a high voltage circuit and an ionic wind is created between the electrode and duct. The ionic wind sweeps particles in the air to the duct which provides a collector electrode. In another embodiment, a ring collector electrode is also provided for spanning the inner portion of the duct. The high voltage circuit comprises a DC power supply, a high voltage transformer, a high voltage multiplier stage and a push-pull switching circuit. The DC power supply receives AC power and generates a DC output which is coupled to the primary of the transformer. The push-pull switching circuit produces a controlled and efficient AC output in the transformer by alternately switching the primary winding. The output voltage from the secondary winding is further increased by the multiplier stage to a level sufficient to energize the electrodes and produce the ionic wind. The apparatus also comprises a high voltage multiplier stage.

Abstract: In an engine starter including a solenoid device for actuating a switch for the electric motor and to drive the pinion into mesh with the ring gear of an internal combustion engine, the solenoid device includes an armature outer member which moves in the direction to push out the pinion against the spring force of a first return spring in the energized state of the solenoid device, and an armature inner member which is resiliently urged by a second return spring,and is telescopically disposed with respect to the armature outer member with a coil spring interposed coaxially between them. An annular spring retainer is press fitted into the inner bore of the armature outer member to receive a corresponding coil end of the coil spring. The spring retainer is stamp formed from non-magnetic material so as to have cylindrical portion which is fitted into the bore of the armature inner member, a flange portion which is bent perpendicularly from the cylindrical portion in the manner of an inwardly directed flange tin its installed state, and a guide piece portion which is bent perpendicularly with respect to the axial direction from the free end of the flange portion. The forming of the armature outer member is thereby simplified, and the guide piece portion supports the coil spring with a centering action. More importantly, the spring retainer which may be made of non-magnetic material can prevent any significant leakage of magnetic flux from the spring retainer.

Abstract: A child resistant switch lock having a body and a slide which can be installed over an existing mounted toggle-type or rocker-type switch. The slide is arranged to operate the toggle handle or rocker between an on and off positions. Stopping tabs on the body prevent movement of the slide from the off to the on positions unless the stopping tabs are first depressed. The required two handed operation, one to depress the stopping tabs and one to advance the slide, make operation by a child very difficult. The slide can operate the toggle handle of a toggle-type switch directly or the rocker of the rocker-type switch through intermediate cams contained in the body.

Abstract: A gas flow distribution system accumulates a sample from a sample bearing carrier gas in a micro-accumulator, delivers it using a carrier gas to a gas-chromatography column, and supplies a carrier gas to the gas-chromatography column to facilitate separation of the sample into sample components and transport the sample components to a mass spectrometer for trace vapor detection and analysis or testing in real time. The system is made of inert components and configured to have low dead volume for improved performance and accuracy of detection. External valves are employed for easy management and balance of the flow in the system to minimize operation time and facilitate continuous accumulation, delivery, and testing of the sample. The delivery of the sample to the gas-chromatography column using an electrically heated cold trap as the micro-accumulator can be performed extremely fast. By further combining the sample accumulation phase and the sample testing phase, real-time operation of trace vapor detection is achieved. Because the step of delivering the sample to the gas-chromatography column is performed quickly, the accumulation of the sample can resume quickly and is nearly continuous for improved efficiency.

Abstract: A press for pressing a mat into a thin panel has a press frame, upper and lower press plates on the frame, upper and lower press belts having confronting lower and upper stretches defining a press gap extending in a horizontal and longitudinal transport direction and respectively running below and above the upper and lower press plates, respective arrays of rollers between each press plate and the respective stretch, and upper and lower flexible intake plates juxtaposed respectively above and below upstream ends of the lower and upper stretches of the belts and defining therewith an intake mouth flaring upstream. In accordance with the invention an array of spaced differential hydraulic actuators is braced between at least one of the intake plates and the frame and is operable to deform the one intake plate and thereby change the spacings of the belts at the mouth. A controller connected to the actuators can therefore steplessly change the shape and position of the belts at the mouth.

Abstract: In a method of using iris recognition to determine whether a person is authorised to pass a security check, the person is first identified by comparing a captured and digitised iris code with iris codes stored in a database of iris codes for authorised persons. Then, the iris code for an identified person is compared with all previously recorded iris codes for that person. If there is an exact match, the identified iris code is deemed irregular since the changes of obtaining an exact match are significantly low. As a result, either further identifying information is requested or access to resources or systems is denied to the person.
