IPC: H01J65/04
Filed: 1992-11-13
Abstract: Abstract of the Disclosure As  a  result  of   inserting an  additional capacitance in the form of an additional molding (12'') composed of dielectric material in the inner space of a UV excimer radiator, it is possible to enforce a loss-free control of the axial and/or radial distribution of the power consumption and UV intensity.          In the irradiation of wide substrates such as sheets, papers and the like coated with paint, lacquers or adhesives, in particular, this measure is advantageous if all the regions of the substrate are to be irradiated with approximately the same dose.

Abstract: FIBER BLENDING SYSTEM                  Abstract of the Disclosure A fiber blending system includes an apparatus and method of forming a mat of cellulosic fibers and synthetic fibers, as well as a mat thereby formed.  The method includes the steps of fiberizing cellulosic material into cellulosic fibers in a fiberizer, volumetrically metering a metered amount of synthetic fibers, and injecting the metered amount of synthetic fibers into the cellulosic fibers.  The cellulosic fibers are blended with the metered amount of synthetic fibers in a blending chamber to form a fiber blend.  The fiber blend is dispersed through a fiber disperser having apertures of a preselected size and shape to provide a dispersed fiber blend.  A third type of fiber may also be mixed with the dispersed fiber blend.  The dispersed fiber blend is collected as a mat on a fiber collector to provide a mat of blended cellulosic and synthetic fibers.  The mat may be thermobonded by a thermobonder and sandwiched between a facing sheet and a backing sheet.  By varying the aperture preselection, as well as the size and type of fibers, a bonded mat having desired mat characteristics is formed.

Title: Electro-pneumatic spring and service brake actuator
Inventor: LATVALA BRUCE E
IPC: B60T17/08
Filed: 1991-06-13
Abstract: An electro-pneumatic braking system includes a tandem brake actuator (12) including a service brake actuating section (16) and an emergency/parking spring actuated section (18). Hold-off pressure is communicated to the emergency/parking section through a three-way solenoid valve (54) from a pressure reservoir (42), and communication to the service actuator is controlled by electro-pneumatic modulator (56). Service pressure is taken both from the branch of the conduit communicating with the air reser-voir (42), but also from the hold-off pressure in the emergency/parking reservoir (34). Accordingly, only a single line communi-cates fluid pressure from the reservoir to the brake, and service brake response; time is improved because the hold-off pressure and the emergency/parking section of the actuator is used as a small reservoir immediately adjacent the service actuator.

Patent CA-2103615-A1 (CA)
Inventor: LEE RON C
IPC: B01J4/00
Filed: 1993-08-09
Abstract: A liquid cryogen is supplied, preferably by means of a reservoir, to a dispensing tube so that the liquid cryogen tends to flow from the dispensing tube. A heating coil wrapped around the dispensing tube heats the dispensing tube so that the liquid cryogen undergoes nucleate boiling within the dispensing tube to form a vapor block, and thereby at least impede the liquid cryogen from flowing from the dispensing tube. Flow is reestablished within the dispensing tube by terminating the heating of the dispensing tube, eg. by turning off electrical power supplied to the heating coil. The heating of the dispensing tube can be sufficient to stop the flow of liquid cryogen. Additionally, the dispensing tube can be cyclically heated by a timing circuit connected to the heating coil. Such cyclical heating is used to throttle the flow of the liquid cryogen from the dispensing tube.

Abstract: A gas investigation apparatus is provided herein to determine the amount of gas in a liquid. The apparatus includes a hollow, longitudinally-extending cylindrical barrel for holding a liquid and a sample liquid with gas dissolved therewithin and with an associated gaseous headspace above. The barrel has a lower inlet and an upper outlet. At least a portion of the barrel is transparent. A plunger is slidably-fitted in a leak-proof manner within the barrel, the plunger being free to slide along the longitudinal length of the barrel, thereby forming a variable volume of air and gas in the headspace.  A gas inlet tube has a lower inlet, and an upper outlet within the plunger and extends along the longitudinal axis of the plunger. A longitudinally-extending, heat transfer jacket surrounds the cylindrical barrel for the regulation of the temperature of the liquid sample. An upper valve is connected to the upper outlet of the barrel by means of a zero dead-space, butt-end connection. Selective entry means is provided through the upper valve for admitting a study liquid or tissue suspension into the barrel. A lower valve is connected to the lower inlet of the gas inlet tube by means of a zero dead-space, butt-end connection. An inlet conduit is provided for the selective introduction of test gas, a calibration gas, a carrier gas, or a flushing gas into the gas inlet tube through the lower valve. An inlet tube is provided for the selective introduction of a gas sample into the inlet conduit means through the lower valve. Finally, an exit tube is connected to the upper valve by means of a zero dead-space, butt-end connection, for leading gas exiting from the plunger-position-dependent variable volume of gaseous space at the upper portion of the barrel to a mass spectrometer.

Title: Dual channel glass break detector
Inventor: SMITH RICHARD A
IPC: G08B13/04
Filed: 1993-02-05
Abstract: A glass break detector for detecting the breaking of a window or the like comprises an acoustic transducer (XI) having a wide band frequency response, coupled to a dual channel filter and signal processing circuit. A low frequency channel (10, 20) detects an initial positive compression wave caused by the inward flex of the window and a high frequency channel (40, 50) detects the acoustic spectrum which is characteristic of breaking glass. The two channels are combined in a logic circuit (30, 60) that is timed so that the low frequency positive flex is detected initially with the high frequency component following shortly thereafter. If both timing conditions are fulfilled, an alarm (100) is initiated. Additional circuitry (70, 80, 90) is provided to inhibit the alarm if a negative compression wave is initially detected. The detection sequence is initiated by a loud sound characteristic of breaking glass.
