Abstract: ABSTRACT OF THE DISCLOSURE                    TRACK CIRCUIT         There is described a track circuit for use with a track section which may or may not include a switch.  The circuit provides means for detecting the presence of a rail-road vehicle within the track sections as it constitutes a shunt across the track.  The track section is divided into a plurality of segments with each segment having a common bounda-ry with at least one other segment.  Alternating current sig-nals are induced into each track segment and sensing means are provided for responding to the induced a.c. signals.  Modulating means are provided for intermittently affecting the signal sensed by the sensing means and a detecting means is provided for detect-ing and responding to the changing signal sensed by the sensing means.  The detected signals are gated through a logic circuit which provides first and second outputs indicating:  the changes are as might be anticipated as a result of the modulation intro-duced; or, that the changes are other than might be anticipated as a result of the modulation, respectively.  The shunting effect of a railroad vehicle in any segment will cause the production of the second type of output signal and, therefore, the second type of output signal is an indication of a railroad vehicle within the track section.

Abstract: ABSTRACT OF THE DISCLOSURE           An improved single acting dual piston positive displa-cement pump suitable for manual operation and suitable for use in portable equipment such as a water purification unit.  A pump with a rack and pinion gear drive, with the rack gear formed in-tegrally with the piston was developed for use with a purifier utilized by hikers who must obtain their water from the land over which they travel   However, this pump was found not to be satisfactory.  In particular, there was excessive wear in the moving parts and substantial corrosion during use.  Also, the pump was difficult and tiring to the operator.  The present in-vention proposes to overcome the disadvantages of the prior art pump by providing a pump which is suitable for manual operation as well as for motor driven operation, and one which provides a maximization of pumping forces with a minimization of reactive forces and operator fatique.  The single acting positive displa-cement pump according to the present invention includes cylinders, valving and manifold which may be directly interconnected within the pump housing, thereby  eliminating interconnecting tubing and fittings.  The piston drive mechanism for the pump may be separa-ted from the fluid passages and wherein the pistons, cylinder housing and head or manifold may be made of an acetal plastic which has high corrosion resistance and low friction coefficient, as well as strength and dimensional stability in the water en-vironment.  The pump is suitable for applications in addition to water purifiers, in both portable and fixed configurations.

Abstract: FACSIMILE DATA COMPRESSION METHOD     ABSTRACT OF THE DISCLOSURE        A method for compressing, transmitting and repro-ducing facsimile data using data bits of picture elements which are included in a plurality of scanning lines, which method reduces the required bandwidth in order to transmit said facsimile data.  In this method, at least one status of a data bit which is positioned at the head of serial data bits obtained by scanning said facsimile data is changed to a reference status, or a reference status is placed before said serial data bits.  As the status of the first data bit of the serial data bits is predetermined, it is not necessary to send information of the status of the first data bit to a receiving side, so that the information of the facsimile data can be transmitted by one synchronizing code, transition codes or mode codes and run length codes.  In this way, a mode code which repre-sents the status of the first data bit of the serial data bits need not be sent.

Abstract: SEMIAUTOMATIC DOCUMENT HANDLER              Abstract of the Disclosure A semiautomatic document feed apparatus for use in feeding single sheet original documents onto a horizontal document glass of an electrophotographic copier.  Upon production of the requested number of copies, the original document is fed to an exit tray.     The document feeding mechanism is contained within a pivoting document cover which overlies and covers the document glass. This cover is spring biased to assume a generally open position, allowing operator access to the document glass.  A permanent magnet latch cooperates with cover and the copier's frame, at a position adjacent the document glass, to hold the cover closed.  This permanent magnet latch facilitates manual cover opening merely by manually lifting the cover.  A mechanical camming mechanism is contained within the cover and is operable to separate the cover from the frame, thus introducing an air gap into the magnetic latch, and allowing the cover to open as a result of its spring bias.          The camming mechanism is operated by an electromagnetic device which is mounted adjacent the cover's pivot, to thereby reduce the cover's inertia.

Abstract: MALFUNCTION DETECTING APPARATUS FOR USE IN A              CRT DEFLECTION CIRCUIT                 ABSTRACT OF THE DISCLOSURE           Apparatus is provided for preventing the generation of an excessively high voltage by the high voltage circuit of a CRT device, such as a television receiver, thereby avoiding the danger of producing injurious X-ray radiation and further minimizing the potential fire hazard attributed to such an excessively high voltage.  A flyback transformer is connected to a resonant capacitor and is driven by a switching device synchronized with horizontal scanning pulses so that flyback pulses are produced during the normal retrace intervals in the horizontal-deflection.  A relatively low voltage power supply is coupled to the switching device to apply an operating voltage thereto.  A first detecting circuit is coupled to the flyback transformer for detecting a high frequency component included in the flyback pulses in the event of a malfunction of the resonant capacitor, such as a disconnection of that capacitor, which high frequency component causes an excessively high voltage to be produced by the high voltage circuit.  A second detecting circuit is coupled to the flyback transformer for detecting a high flyback pulse level that is produced when the operating voltage applied by the low voltage power supply exceeds a pre-determined level. In the event that the first detecting circuit detects the presence of a high frequency component or the second detecting circuit detects a high flyback pulse level, a switch is actuated to control the CRT deflection circuit, thereby reduc-ing the level of the flybacks pulses, and thus the level of the high voltage produced by the high voltage circuit.     -i-
