Abstract: ELECTROCHEMICAL CELL Abstract of the Disclosure A primary electrochemical cell of a design for reducing or minimizing parasitic self-discharge of the cell during storage and subsequent discharge of the cell. The cell includes a tubular porous carbon cathode struc-ture disposed within a metal housing of the cell and spaced from an anode structure by an insulative separator material.  The carbon cathode structure and the anode structure are exposed to an electrolytic solution includ-ing a reducible soluble cathode (e.g., thionyl chloride) which is catalytically reduced during discharge of the cell at the surface of the carbon cathode structure.     The anode structure includes an elongated, cylin-drical lithium electrode located centrally within, and spaced from, the housing, and a thin, bare, flexible metal element at the potential of the lithium electrode and coupled between the lithium electrode and a feed-through member provided in a top cover of the housing. The surface areas of the flexible metal element and the lithium electrode are established such that the surface area of the wire is about 1-10 percent of the initial (pre-discharge) surface area of the lithium electrode for minimizing the parasitic catalytic reduction of the soluble cathode at the surface of the flexible metal element.  The flexible metal element and feedthrough member may also be covered with an anti-parasitic discharge material for preventing catalytic reduction of the soluble cathode at the surfaces of the flexible metal element and feedthrough member covered with the anti-parasitic discharge material.

Abstract: TOKEN MECHANISM WITH MAGNETIC SEPARATION MEANS                 ABSTRACT OF THE DISCLOSURE     A token which cannot be easily counterfeited by inexpensive methods and a simple token acceptance mechanism which will reject easily-made counterfeit tokens.  The token is a disk-shaped object which has two sections along its axis.  One section has a notched periphery and the second section has a smooth periphery.  The notched section interacts with a pawl in the token acceptance mechanism and the smooth section interacts with an arm.  The pawl and arm are interlocked so that only tokens which contain both the notched section and the smooth section are accepted.  Therefore tokens which can be easily made by stamping or by turning on a lathe are not accepted by the mechanism.  A chute with a barrier projecting from one sidewall and a magnet adjacent the opposing sidewall acts to pass semi-magnetic tokens but trap non-magnetic or wholly magnetic tokens.

Abstract: Abstract:  Method of recognizing speech pauses.     The described method of recognizing speech pauses in a speech signal enables the recognition of a pause also when a slowly varying noise signal is superposed on the speech signal.          For the purpose of speech pause recognition, mean values which are an approximate measure of the average power of approximately 100ms-long sections of the disturbed signal are determined from short-time Fourier coefficients of the disturbed speech signal. The sequence of these short-time mean values are then smoothed by means of linear filtration or using a median filter. An estimate of the noise signal power averaged over a few seconds is recovered from the sequence of short-time mean values in parallel with the smoothing operation.          When the smoothed short-time mean value is more than once below a threshold which is proportional to the above-mentioned estimate, then it is decided that there is a speech pause.

Abstract: ABSTRACT In a video display monitor having a multiple rate scanning capability, a synchronized switching power supply develops the regulated operating voltages for the monitor.  A deflection circuit produces scanning current in a deflection winding and is capable of being operated at either one of two selectable scanning frequencies.  A signal synchronously related to the scanning current, such as a retrace pulse voltage, is applied to the control circuit of the switching power supply.  The control circuit generates a control signal from the retrace pulse voltage that is synchronously related to the scanning current and of a frequency that is unchanged when the deflection circuit is operated at either of the two selectable scanning frequencies.  The output stage of the switching power supply responds to the control signal and produces switching operation at the unchanged frequency in synchronism with the scanning circuit.

Abstract: HIGH VOLTAGE POWER SUPPLY                         Abstract A high voltage power supply is formed by three discrete circuits (12, 14, 16) energized by a battery (18) to provide a plurality of concurrent output signals floating at a high output voltage on the order of several tens of kilovolts.  Each circuit has a regulator stage (20, 28,  36).  In the first two circuits, the regulator stages are pulse width modulated and include adjustable resistances (R1, R2) for varying the duty cycles of pulse trains provided to corresponding oscillator stages while the third regulator stage includes an adjustable resistance (R3) for varying the amplitude of a steady signal provided to a third oscillator stage.  In the first circuit, the oscillator (22), formed by a constant current drive network and a tuned resonant network including a step-up transformer (46), is coupled to a second step-up transformer (24) which, in turn, supplies an amplified sinusoidal signal to a parallel pair of complementary poled rectifying, voltage multiplier stages (76, 76') to generate the high output voltage.  Each of the other two circuits include oscillator drive stages (30, 38) which, together with isolation transformers (32, 40) provide output signals floating at the high output voltage.

Abstract: ABSTRACT OF THE DISCLOSURE A dispensing device suitable for use in dispensing predetermined, in succession quantities of fluid from a reservoir member in the device is disclosed.  The device, consists of an elongated body which further consists of separable top and bottom sections.  The top section of the elongate body contains the functions for mechanically advancing an axially movable piston rod which itself drives a piston plug located inside of the reservoir member so as to express fluid from the reservoir via a needle located at the front or the bottom end of the body.  The piston rod which is threaded, advances in successive axial steps of fixed length through rotation of a rotatable piston rod nut whose threads interact with the threads on the piston rod.     The piston rod nut is driven by a rotatable worm or screw, which in turn is rotated by advancing axial movement of a pressure device located at the top of the elongated body.          The user pushes the pressure device directly or indirectly to dispense the fluid.  A unidirectional transmission system couples the pressure device to a rotatable screw and the screw to the piston rod nut so that the piston rod nut rotates only when the pressure device is pushed into the elongated body.  The elongated body is comprised also of a bottom section, inside of which is the reservoir member and at the bottom end of which is a double-pointed hollow needle with one point extending axially out from the elongated body and the other point extending axially inside the body and into the reservoir member.

Abstract: Abstract of the Disclosure The invention is directed to a safety link for a saw chain of a motor-driven chain saw.  The safety link has a plate-like body including a rearwardly extending safety projection when viewed in the direction of movement of the saw chain.  The safety projection serves to bear against the bottom of a kerf cut by the saw chain.  To provide a large and safe bearing surface for abutment with the kerf bottom, the safety link has a widened portion extending at least over and beyond one side of the plate-like body thereof.  The widening is formed either by bending or flattening a longitudinal edge of the body, or by bending the safety projection, or by bending an end portion of the body at the end thereof opposite the safety projection.  The safety link is pivotally connected with side cutting links, center driving links and side connecting links by means of rivets and is located ahead of the respective cutting link when viewed in the direction of movement of the saw chain.  With the safety link and the cutting link of the invention, it is possible to achieve a substantial reduction in the tendency of a motor-driven chain saw to kickback and to ensure smooth running and clean cutting conditions.
