Abstract: ABSTRACT      A wet pick-up type vacuum motor fan unit with a separately ventilated motor section and a motor end bracket serving also as a support for, and part of a discharge end housing wall for, the working air fan section, has on the bracket fanward face a centrally apertured metal disk plate defining a flow space or path for bearing sealing air flow from ambient air inlets external of the motor section to a central discharge into the inlet eye of an auxiliary fan clamped on the shaft back-to-back with a larger diameter working air centrifugal fan adjacent the end bracket.  A stamped shield cup jointly clamped on the shaft with the fans extends out of the auxiliary fan inlet eye into the disk central aperture, surrounding the shaft bearing socket of the bracket and being spaced from the disk aperture edge to afford a sealing air outlet from said space into the auxiliary fan inlet eye; whereby the disk plate and shield afford mechanical shielding, while air, discharging to and from the auxiliary fan, provides air shielding of the shaft and bearing area from working air entrained foam and moisture.

Abstract: SENSING CIRCUIT FOR SEMICONDUCTOR CHARGE TRANSFER DEVICES            Abstract of the Disclosure A sensing circuit is disclosed for detecting and amplifying the output signal of a semiconductor charge transfer device, particularly of the transversal filter type containing sensing split-electrodes for sensing the charge packets being transferred through the device.  The circuit includes two amplifier means, one of which suppresses the (useless) common mode signal and the other of which detects the (useful) difference signal of the split-electrodes.  In addition, the sensing circuit is provided both with "reset" switching means for eliminating spurious signals  due to stray charges that accumulate on the sensing electrodes and with "clamping" switching means for eliminating noise of the kTC type generated by the "reset" switching.

Abstract: Abstract of the Disclosure AC type electromagnetic device with simplified electromagnetic exciting coil circuit is provided.  The coil for electromagnetically driving an armature comprises a first coil of a relatively larger winding number and excited during every half cycle of AC source current and a second coil of a relatively smaller winding number and wound in reverse direction to that of the first coil, so that the armature will be driven by a composite magnetic flux of both fluxes occurring every half cycles due to the first and second coils.  For said excitation of the first coil, a single diode is connected in-series with the first coil with the second coil connected in parallel therewith, or in parallel with the first coil with the second coil connected in series therewith.

Abstract: INVENTOR:     ALBERT T. BUTTRISS TITLE   :     FASTENER EMPLACEMENT MECHANISM                         A B S T R A C T           An automatic fastener emplacement mechanism for selectively applying fasteners, such as spring clips, to a work piece is provided.  The mechanism preferably includes a vibratory hopper or other storage means for receiving the spring clips in bulk and properly orienting same on a track and an assembly tool having a nose piece for properly positioning the tool relative to the work piece and a ram for driving the fastener onto the work piece.  Placement of the work piece properly within the nose piece will result in contact and/or displacement of an actuation member or trigger by the work piece which will cause a single fastener such as a spring clip to be fed, preferably by known means such as pneumatically through an escapement down a delivery tube, directly from the hopper track to the work piece.  The clip is held in the nose piece against the work piece by the continued introduction of compressed air into the tube.  Thus, the nose piece does not require a stop member or a catcher/holder mechanism.          The actuation or trigger member is preferably located well within the nose piece, which will result in a clip normally being fed from the hopper only when a work piece is properly positioned within the nose piece.  The actuation member is preferably located to resist intentional and/or unintentional contact by means other than a properly positioned work piece.  As the nose piece is moved slightly away from the work piece, the actuation member will cease to be contacted and/or displaced by the work piece which will cause a ram to drive the spring clip onto the work piece and will terminate the provision of compressed air into the delivery tube.

Abstract: ABSTRACT OF THE DISCLOSURE      The specification teaches a method of enriching a catalyst system in which both platinum and rhodium are present. The enrichment increases the amount of rhodium which is actively available for use as a catalyst.  The enrichment is brought about by thermally aging the catalyst system in an oxidizing atmosphere by heating it to a temperature in a range from 650°C to 875°C for a period of at least tow hours.  A thermal aging at a temperature of about 800°C for a period of 4 to 8 hours is preferred.

Abstract: ABSTRACT OF THE DISCLOSURE                A standpipe type sensing apparatus for a baromatric or gravity induced flow oil level regulator for maintaining oil in an engine crankcase at a desired level has a vent which places an air space in the standpipe in fluid flow communication with a relatively oil free portion of a relatively calm air space above the oil level in the crankcase.  The vent assures that the air pressure in the standpipe air space and in the crankcase air space are substantially equal during operation of the engine. A fluid flow damping orifice is provided to retard the  rate of fill and drainage of oil from a sensing chamber in the stanspipe.  The standpipe apparatus is readily installed onto engines without the need to remove the oil pan.

Abstract: ABSTRACT         Hitherto it has not been possible to find a uniform form of construction for hearing aids.  At the present time there are several hundred models on the hearing aid market which can be sorted into classes only by individual parameters.  In an illustrated embodiment a behind-the-ear hearing aid includes a microphone, an amplifier-low pass filter circuit, an analog to digital converter, a digital integrated circuit arithmetic and logic unit for implementing a n-th order transfer function in the Z domain, a digital to analog converter and an output transducer, for producing the desired sound response.  A memory multiplexer is provided for loading of the multiplier coefficients necessary to adapt the transfer function circuit to essentially any class of hearing deficiency into an erasable programmable read only memory (EPROM).  The structure is such that the coefficient memory may be loaded after the standard universal hearing aid has been completely assembled, and indeed the hearing aid may be reprogrammed as needed after a period of use, essentially without disassembly.

Abstract: AIR PURIFICATION FILTER AND METHOD          ABSTRACT OF THE DISCLOSURE   The invention provides an air purification filter for use in kitchens, restaurants, living areas and the like.  The filter is provided in a housing having an inlet and an outlet for the air, the air preferably being driven through the interior of the housing by a fan.  A microporous filter is provided in the housing, through which the air is constrained to pass.  The microporous filter is directly electrically charged to one polarity and particles in the air are charged to the opposite polarity upstream of the filter so that they carry a charge when entering the microporous filter.  The particles are thus attracted to, and deposited on, the interior surfaces of the microporous filter as the air passes therethrough.  Hence, the filter traps even the minute particles that would normally pass through it.
