Title: Electrostatic spray coating device for electrically conductive , non-inflammable coating liquid
Inventor: SEEWALDT KURT
IPC: H02B1/16
Filed: 1993-11-30
Abstract: Electrostatic Spray Coating Device for Electrically Conductive, Non-Inflammable Coating Liquid Abstract Electrostatic spray coating device for electrically conductive, non-combustible coating fluid.  The coating fluid is accommodated in a pressure container (2) of electrically insulating plastic and connected over a tube (10) of electrically insulating material with a spraying devices (B).  An electric conduction path (53) leads off high voltage from the coating fluid (6) which present in the pressure container (56) when the high voltage is switched off.  Thereby the electrical capacitance of the device is reduced and simultaneously it is ensured that after the switching-off of the high voltage the coating fluid present in the pressure container (2) in few seconds is no longer electrically charged.  Thereby, immediately after the switching-off of the high voltage, the pressure container (2) can be opened, for example for the replenishing of coating fluid.

Title: Spin blender feed coating
Inventor: HOUGH RICHARD M
IPC: B01F25/74
Filed: 1994-02-15
Abstract: SPIN BLENDER FEED COATING      ABSTRACT OF THE DISCLOSURE Apparatus for applying liquid to particulate materials using a single drive motor to operate both the upper particle dispersing disc and the lower liquid dispersing disc, the latter disc being driven at a much higher speed than the former. The two dispersing discs have coaxial drive, one hollow drive shaft within the other, but are driven at different rotational speeds optimum for the material being dispersed from the respective discs. The liquid is fed through the inner hollow drive shaft to its disc. The particulate feed rate is controllable with a presettable throttling or feed rate regulator sleeve. The sleeve has tooth features cooperative with abutment features of the underlying particle dispersing disc to neutralize lumps, chunks and pieces of paper and the like in the feed material. After the solid particles are coated with liquid, the particles are specially mixed using apparatus that also maintains the housing chamber clean so as not to accumulate product therein to contaminate subsequent materials, and driven by the same single drive motor. This apparatus is particularly advantageous for producing fat coated animal feed and the like.

IPC: A47K3/30
Filed: 1993-12-03
Abstract: A joint between an upper wall part and a lower wall part of a modular tub/shower unit includes a recessed band adjacent to but spaced from the lowermost edge of the upper wall part. A further band is recessed at the uppermost edge of the lower wall part with the vertical height of that band being greater than the vertical height of the recessed band in the upper wall part and greater than a band at the lowermost edge which is not recessed. The lowermost band of the upper wall part is then adhesively attached to the uppermost edge and a part of the recessed band of the part by a double sided adhesive tape the covering of which is pulled through the gap between these parts. The adhesive tape provides the only sealant necessary for waterproofing the joint and provides the only structural strength necessary. The groove above the lowermost band of the upper wall part allows the upper wall part to be maneuvered into the required position by finger engagement into the groove.     The recessed bands adjacent the upper and lower edges of the parts provide stiffening strength. The parts are held together by a pair of spring clips the first of which snaps over the second when the parts reach the overlapped position as limited by engagement of the parts with the first also applying force to the second transverse to the joint to squeeze the adhesive.

Title: Optical demultiplexer for optical/rf signals
Inventor: WAGNER HARVEY LAWRENCE
IPC: H04B10/61
Filed: 1994-08-18
Abstract: ABSTRACT OF THE DISCLOSURE An   optical   demultiplexer   includes   an electrooptic modulator (410) which modulates a beam of light  (418)  in response to frequency-multiplexed  radio-frequency  (RF)  information signals, to produce diverging beamlets of light (420).  The diverging beamlets are separated by a spatial separator arrangement (426), and each beamlet (420), including the information of its RF carrier,  is coupled to a separate optical detector (428).  The detector (428) can extract amplitude modulation from the signal.  In order to reconstruct the RF signal  as well as the amplitude   modulator,    an   optical   "local oscillator"  signal  (OLO)  is  coupled  to  each detector together with its information signal. Signal loss due to vibration or misalignment is avoided,  and heterodyne  mixing  efficiency  is maximized in an embodiment of the invention, by propagating  the  OLO  and  information  signals through  a  single-mode  optical  fiber  to  the detector.   In a particular embodiment of the invention, the OLO signal is applied to a first fiber (622), the information signal is applied to a second fiber (610), and the first and second fibers are coupled together by a  fiber-optic coupler  (612).   In another embodiment of the invention, the OLO signal results from generating an RF L.O.  signal,  and combining the RF L.O. local signal with the information signals before application to the electrooptic modulator,  to generate an OLO beamlet (720) which is subject to the same vibration and misalignment as the signal beamlets.

Title: Ignition transformer
Inventor: NOBLE GARDINER A
IPC: F02P15/00
Filed: 1994-11-01
Abstract: An ignition and engine control system for an internal combustion engine. The system includes a flyback ignition transformer which can rapidly re-fired a spark plug during a combustion cycle to perform various ignition diagnostic procedures using the spark plug as a feedback element of the control system. The transformer is adapted for mounting directly to a spark plug and includes a core about which a primary and secondary are toroidally wound. A controller provides signals to a circuit which causes maximum charging of the transformer for ignition and subsequent charging of the transformer for diagnostic purposes. The system also includes a diagnostic circuit which can detect the occurrence of an electrical discharge, and/or its duration, across the spark plug as a result of one of the diagnostic charges by monitoring the transformer for a reflected voltage in its primary. The detection circuit outputs a signal to the controller which allows the controller to diagnose conditions within the combustion cylinder.
