Title: Safety interlock for the food pusher in a food  processor

Abstract: 1022.019 GKP                  S P E C I F I C A T I O N              SAFETY INTERLOCK FOR THE FOOD PUSHER         IN A FOOD PROCESSOR              INVENTORS:  Richard D. Clare and Carl G. Sontheimer ABSTRACT OF THE DISCLOSURE           An improvement in a food processor of the type having a housing enclosing a motor, a drive shaft extending from the housing, a working bowl which is de-tachably mountable on the housing in position to surround the shaft for receiving the various rotatable food processing tools which are removably installed on the shaft, with a removable cover on the bowl.  Food processors of this type normally include a hopper or feed tube which is carried by the cover, and a manually operated pusher or plunger which is used to feed food items down through the hopper onto the rotating cutter blade, slicing disc, rasping tool, etc.          The improvement comprises a safety interlock between a switch actuator associated with the cover and an on-off switch in the housing to permit actuation of the relatively powerful motor drive when the pusher is being properly in-serted within the hopper, thereby preventing a user from in-serting a hand down into the hopper where there is risk of inadvertently encountering injury from a rotating tool in the upper portion of the bowl.  By virtue of this interlock, the feed tube can safely be made to have a larger cross-sectional area so that larger food items can be inserted whole into the food processor.  Moreover, the entire size of the working bowl, cover and feed tube can be proportion-ately enlarged for providing a larger overall machine.

Abstract: SURGE VOLTAGE ARRESTER WITH VENTSAFE FEATURE            Abstract of the Disclosure A surge voltage arrester assembly for protecting telephone lines comprises a primary gas tube surge arrester and an air gap secondary arrester that provides surge pro-tection should the gas tube become vented to atmosphere. The secondary arrester has the air gap defined by a rim of one of the gas tube electrodes and a metallic cup into which the gas tube is positioned.  In a three element version of the invention wherein the gas tube has two line electrodes and a ground electrode, metallic cups are provided at opposite ends of the gas tube to cooperate with the ground electrode for forming secondary air gaps for each line electrodes.  An O-ring and a sealing compound seals each secondary air gap against the entrance of contaminants.

Abstract: IMPELLER LUBRICATION SYSTEM FOR TRANSMISSION POCKET BEARING                                Abstract An impeller lubrication system provides lubrication oil flow to a transmission pocket bearing.  Splash and spray lubrication oil is directed from the transmission casing to a collector region along a shaft adjacent the pocket bearing.  As the shaft rotates, oil is forced axially along the shaft by an impeller fixed to the shaft.  The impeller forces the oil from the collector region to the pocket bearing through a lubrication port in the shaft.

Abstract: AN IMPROVED ELEVATION SETTING MECHANISM              FOR A TABLE SAW AND THE LIKE               ABSTRACT OF THE DISCLOSURE    There is disclosed an elevation setting mechanism for a motor-driven tool in a power tool apparatus such as a table saw.  The table saw described includes a housing having a table top with an opening through which the motor-driven tool in the form of a saw blade can pass, and an assembly including a frame pivotally mounted in the housing about a first axis.  Pivotally mounted in the frame about a second pivot axis is a first subassembly which includes the saw blade.  Further, there is included a second subassembly pivotally mounted about the second pivot axis.  The basic elevation setting mechanism includes a control lever operatively connected to the second subassembly for pivoting same, and means connecting the two subassemblies, such that they pivot in unison, in response to action of the control lever, for purposes of setting the tool at a coarse level.  The mechanism further includes a second control mechanism operatively connected to the first subassembly for imparting additional pivotal movement thereto for effecting a vernier elevation adjustment of the saw blade.  It is in this latter adjustable feature wherein the improvement of the invention lies.  The invention is directed to a pivot nut pivotally mounted in the first subassembly, the pivot nut having a threaded opening perpendicular to its pivot axis in the first subassembly.  A connecting rod includes a threaded end which is disposed and threadably engages a threaded opening in the pivot nut.  Means are disclosed which restrain axial movement of the rod towards and away from the pivot axis of the pivot nut.  When the connecting rod is rotated, the pivot nut is caused to translate with respect to the connecting rods and the pivotal mounting of the pivot nut converts the rotational movement of the rod into pivotal movement of the first sub-assembly about the second pivot axis whereby the further vernier elevation adjustment of the saw blade is effected.

Abstract: MOTOR FIELD EXCITER                 ABSTRACT OF THE DISCLOSURE Disclosed is an exciter circuit for an electrical load such as the field winding of a direct current (DC) motor.  The exciter circuit regulates the DC current applied to the load from an alternating current (AC) source in response to an isolated feedback signal developed by means of a saturating square loop current transformer.  The current signal developed is compared against a signal corresponding to the desired current value and an error signal is generated which is fed to photo-optical firing circuit means which are coupled to and operative to control at least one thyristor (SCR) which, when rendered conductive, is adapted to provide a freewheeling current path for the load current during the half cycle of the AC line voltage when it is disconnected from the load by at least a half wave rectifier.  The present invention includes embodiments for both single and bidirectional current flow through the load which, as noted above, preferably comprises the field winding of a DC motor.

Abstract: D-3,868   C-3201 Abstract of the Disclosure A capacitive probe for sensing the presence of water in a fuel tank increases in capacitance when water is present.  A threshold detector circuit includes the capacitive probe and a reference capacitor and an oscillator for periodically charging them to the same voltage and a comparator for comparing the capacitor voltages during discharge to determine when the probe capacitance exceeds the reference capacitance.  The comparator controls a lamp driver which is connected to ground and which is also connected by a single conductor to a remote indicating lamp in series with a power supply.  The single conductor carries the lamp energizing current as controlled by the lamp driver and also supplies the operating voltage to the detection circuit.  The resistance of the incandescent lamp varies with applied voltage so that the voltage presented to the detector circuit is partially regulated by the lamp resistance so that large changes in the power supply voltage are only partially reflected in the threshold circuit operating voltage.

Abstract: ADAPTIVE CROSS-POLARIZATION INTERFERENCE         CANCELLATION ARRANGEMENTS            Abstract The present invention relates to an adaptive cross-polarization cancellation arrangement where a first desired polarized signal and a second interfering orthogonally polarized signal, including cross-polarization components, are concurrently received at an antenna.  In the present arrangement, the orthogonally polarized components of the received signal are separated and transmitted along separate paths and recombined after the phase and amplitude of the separated polarized interfering signal sample has been appropriately adjusted for maximally cancelling cross-polarization components thereof in the other path.  A feedback path includes circuitry for obtaining a sample of any remaining interfering signal in the recombined output signal, generating a signal representative of the power envelope of such sample, and then generating appropriate control signals in response to such representative of the power envelope signal to provide improved adjustment of the amplitude and phase of the separated polarized interfering signal sample.
