Abstract: ABSTRACT OF THE DISCLOSURE   A process and system for the purpose of running and controlling elec-trical high-voltage power lines, particularly of the pertinent generators, wherein a line identification is required with the determination of the longitudinal equivalent reactance of each line section coupled with a mea-suring point or with a generator connected there,  the generator being represented by this longitudinal reactance between the measuring point and a point on the line with amplitude and phase-rigid line voltage.  The reac-tance is determined continuously from the local measured dimensions (P, Q, V1) by using a majority of predetermined values (Xe1-Xe3) of the searched for reactance through similarity comparison of the time developments of phase angle differences (d1 to d3) formed by the predetermined values (Xe1-Xe3) and the local phase angle (dm).

Abstract: SHELF HEIGHT SELECTOR   Abstract of the Disclosure: A shelf height selector system for a lift truck provides signals to an operator as he raises or lowers a load carriage relative to a storage shelf level selected by a keyboard in order to perform a store or retrieve operation, and automatically stops carriage movement with load forks at the proper elevation. Pulses from an incre-mental shaft encoder operated by carriage movement are counted to pro-vide an instantaneous elevation signal upon which indications to the operator and control functions depend. A switch on the truck mast is operated by carriage movement to repeatedly recalibrate a register containing the instantaneous elevation signal, obviating any errors should noise affect tallying of encoder counts. An optical sensor carried on the load carriage to sense reflective markers adjacent some shelves also recalibrates the register, obviating positioning errors due to mast deflection and tire wear.          Provision of a simple programming arrangement allows storage of shelf heights in a non-volatile random-access memory, affording the advantages of a field-programmable system.

Abstract: ABSTRACT:           An electronic transmitter for direct current telegraphy systems.  In order to limit cross-talk between neighboring telegraph lines it is known to filter tele-graph signals prior to transmission to "round-off" their edges.  In the present electronic transmitter telegraph signals are given approximately n sinusoidal edges" by the use of a function generator.  The electronic transmitter comprises an input circuit, a switching circuit and an output circuit.  Binary information signals at an input produce telegraph signals on a telegraph line.  The out-put circuit comprises  two function generators and a cur-rent source.  Two switches in the switching circuit con-trol which function generator is operative in response to command signals D1 and D2 from the input circuit.  The result is that current pulses from the current source have exponentially varying leading and trailing edges which approximate the sinusoidal edges.

Abstract: METHOD AND APPARATUS FOR ANALYSIS OF MEAT PRODUCTS                Abstract  of the Disclosure Rapid and accurate determination of the fat, moisture, and protein content of meat products such as beef or the like is obtained by exposing a sample (49) to microwave energy for a period of time sufficient to achieve a relatively constant chemical analysis in the residue.  During heating on a weighing device (10), a substantial portion of the moisture in the sample is vaporized and a substantial portion of the fat is melted and collected in a separate container (70) which is maintained below the sample (49) but off of the weighing device (10).  By monitoring the time rate of change of weight loss in the sample until it reaches a predetermined value and terminating cooking, a relatively constant chemical analysis of the residue is achieved.  Collection of rendered fat off of the weighing device avoids erratic fluctuations in weight readings caused by spattering, dripping, and explosions of the melted fat in the collection container (70).

Abstract: ABSTRACT OF THE DISCLOSURE           An  image  input  terminal  (IIT)  with  automatic document handler for feeding documents to be scanned into registered position on the IIT platen.  The IIT includes a pair of multi-element scanning arrays with cooperating scan lamp and optics on a movable carriage disposed in scanning relationship with the platen.  Analog image signals gener-ated by the scanning arrays are  initially processed  in separate channels and then combined into a serial stream. The  stream  of  analog  image  signals  may  optionally  be thresholded  or  screened  to provide  binary  level  image signals or converted to multi-bit gray scale.      A control system including microprocessor pro-vides timing and control signals for synchronizing oper-ation of the scanning carriage, document handler, and image signal  reading  and processing  together  with  electronic crossover between arrays to avoid loss of data, automatic signal gain and deletion of bad image signals or pixels. On board array alignment apparatus permits adjustment of array focus, skew, height, position and overlap.

Abstract: ELECTRICAL CIRCUIT FOR PRODUCING           CONTROLLED HIGH VOLTAGE AC OUTPUT    ABSTRACT OF THE DISCLOSURE        An electrical circuit for providing an adjustable and highly controllable, high voltage AC waveshape to a load from a low-voltage, DC source.  This highly controlled waveshape allows accurage reproduction of almost any low-frequency AC reference through an intermediate high-frequency inverter. The inherent leakage reactance of a high-voltage transformer is used advantageously as a filter for removing the undesired high-frequency component from the output.  Economy in parts count and power losses results from the use of a single power handling inverter to perform all adjust, regulation, and waveshape functions.

Abstract: ABSTRACT         A fluid actuator comprises a cylindrical body defining an interior chamber within which is located a piston assembly which isolates fluid outlet means at one end of the chamber from fluid inlet means at the other end of the chamber.  Assembly comprises a central cylindrical piston element concentrically surrounded by at least one annular piston element and is resiliently urged by spring to seat against the end of the body.  Face seals are provided at end for respective piston elements and individual inlet ports penetrate the seals to provide for fluid delivery against individual piston elements.  Adjoining piston elements incorporate a one-way mechanical connection so that spring enables all piston elements to be urged against end Selective application of fluid pressure to one or more of inlet ports enables displacement of one or more of the piston elements towards the outlet port thereby effecting selective volume displacement of fluid from chamber The actuator may be used to provide an incremental movement facility for a hydraulic motor which is also connected to a hydraulic power source for effecting normal continuous operation of the motor.  When the motor is at rest the actuator can be energised to deliver a selected hydraulic volume to the motor thereby causing incremental rotation thereof by a corresponding amount.

Abstract: SINGLE AIR CONDUIT REFRIGERATED DISPLAY CASE          HAVING AMBIENT AIR DEFROST                  ABSTRACT OF THE DISCLOSURE           A single air conduit refrigerated display case having an ambient air automatic defrost system and a method of operating such a case.  The display case has an access opening in one wall for enabling products within the display section to be removed.  The access opening can be either in the top or front wall of the display case.  The single air conduit extends in an approximately U-shaped formation around the display case.  The air conduit has openings at both ends, with such openings being located on opposite sides of the access opening.  Arranged within the air conduit is at least one reversible fan and a set of refrigeration coils.          During a refrigeration cycle the fan circulates air through the air conduit in a first direction towards the refrigeration coils.  When frost buildup within the display case has reached a certain level, the system is switched to a defrost cycle.          During the defrost cycle, the fan circulates the air in the opposite direction through the air conduit and draws in ambient air from outside of the display case.  Since such ambient air is of a higher temperature than the normally refrigerated air, it serves to defrost the system.  The ambient air, after passing over the evaporator coils and through the air conduit, is expelled from the air conduit in a direction towards the outer side of the refrigerated case so as to move away from the interior of the case.
