Abstract: ELECTRICAL TERMINALS WITH LAMINATED PRECIOUS   METAL CONTACTS, WITH SLIDING CONTACT MAKING          Abstract of the Disclosure A terminal having sliding contact with another member has contacts having a main portion of a non-precious metal and a surface layer of precious metal, the surface layer having an arcuate convex cross-section when viewed in a direction normal to the direction of sliding.  This enables a reduction in the amount of precious metal and also avoids shearing of the surface layer by the further member.  The contact material is supplied in strips and short sections cut-off and welded to the terminal member.  The contact can be formed after welding to give the arcuate cross-section, or the strip may be supplied with the arcuate cross-section already formed.  Further forming can be carried out on the preformed material, after welding.

Abstract: ABSTRACT         A smoke detector of the type utilizing a pulsing light source and photo-responsive means producing an output signal in response to the receipt of a pulse of light from said source reflected from smoke particles and means for amplifying said output signal to produce an alarm signal, which has exceptional low current drain so as to be adapted for being powered by a battery, and exceptional immunity to false alarms even when operated at a high sensitivity.  On each pulse, the amplifier is energized and allowed to achieve a stabilized condition, prior to energizing the light source, and after the light source is energized, the amplified output signal is not allowed to create an alarm signal until the circuit has again stabilized from transients caused by the energizing of the light, thereby preventing false alarms from circuit transient resulting from internal and external causes.  The circuit operation is controlled by a master clock which provides a slow pulse rate during stand-by operation and an increased pulse rate when an alarm signal is produced in response to the presence of smoke.  The clock also causes the alarm to be energized by pulses, which pro-vides a more attention-getting alarm signal than does a continuous alarm, and conserves the strength of the battery.

Abstract: ABSTRACT OF THE DISCLOSURE    An apparatus for axial shirring of tubular material.          A turret has a plurality of shirring tubes thereon and is indexible to move the shirring tubes transversely and is also capable of limited axial movement.  A stationary shirring tool cooperates with a shirring tube brought by the turret to a shirring position.  During shirring, the shirring tube is stationary as the tubular material being shirred engages a stop member movable axially along the shirring tube.          First the stop member is brought towards the shirring tool and then controllably moved away therefrom during shirring.          The apparatus also includes a bracing means for centering the folds of the shirred tubular material during the shirring step.  At a further position finished shirred tubular material may be compressed and removed from the shirring tube by a pressing means which can operate independently of and con-currently with a shirring procedure.

Abstract: TEST EQUIPMENT FOR A TELETEX TELEVISION RECEIVER          ABSTRACT OF THE DISCLOSURE         This test equipment permits a testing of the demodulator of a teletex television receiver.   It consists of a digital test signal generator, the output of which is connected to the HF input of the television, and a receiver, the input of which is connected to the video output of said receiver.  The generator transmits pseudo-random data packets having a first frequency of binary elements, with two double-intervaled binary elements at two predetermined instants t1 and t2 for each packet.  The receiver has a data regeneration circuit whose threshold varies line by line from a maximum value to a minimum value.  The sampling clock of the receiver is at a second frequency lower than the first by the ratio (n-2)/n, where n is equal to the integral ratio of the first frequency to the line frequency of the television.  A suitable means insures resynchronization of the sampling clock at the middle of each line.  A receiving circuit for the pseudo-random data detects the errors which are transmitted to the video input of the television.

Abstract: ABSTRACT OF THE DISCLOSURE           A winding for a static induction apparatus such as a transformer, a reactor and the like comprises a plurality of interleaved coils each formed by winding an electrically insulated strand conductor in a radial spiral.  The coils are stacked axially and electrically connected in series between a line terminal and another terminal such as a neutral terminal.  The winding is divided into a plurality of blocks each including a plurality of ones of the interleaved coils.  The number of turns of each coil belonging to the block on the other terminal side is decreased as compared with that of each coil belonging to the block located closer to the line terminal, to thereby reduce the series electro-static capacitance of the coils stepwise from one to another block starting from the one located on the line terminal side.  The distribution constant is thus decreased.  Favorable surge withstanding characteristics are attained, reliable insulation is assured and the winding can be realized in a reduced size.

Abstract: Torque and High Pressure Limiting Control for Variable Displacement Pumps Abstract It is common practice to provide the servo-system for a variable displacement pump with a "load-plus" valve to maintain pump discharge pressure above a minimum pressure level and above a load pressure in a fluid actuator connected to the pump in response to the load pressure in the actuator.  Systems of this type are normally lacking in a device for ensuring that the prime mover for the pump functions at maximum efficiency.  This invention is directed to a pressure and horsepower limiting valve (24) for ensuring such efficiency by modulating a load pressure signal (PL) communicated to the "load-plus" valve (23).

Abstract: Display Refresh Memory With Variable Line Start Addressing Abstract A display refresh system wherein a RAM refresh buffer is tightly packed.  Line start addresses in the buffer are determined by the line length such as eighty characters.  With each of the lines in the refresh buffer being normally a binary number such as 128 characters in length the line start addresses are such that they do not coincide with the beginning of each line in the buffer.  To assure packing they are inter-spersed each 80 positions sequentially within the buffer.          A processor loads the address of each line start charac-ter into the pointer area of the refresh buffer.  A line counter is used which counts the lines being displayed on the display.  The RAM refresh buffer which contains the line start addresses and character data is first addressed by the line counter output to provide the line address.  Since the refresh buffer is used as the line pointer register the output bus for pointer data and character data is common.  Once the address of the first character in a line is read from the pointer area in the refresh buffer it is loaded into the refresh buffer address counter which then controls the sequential reading of characters in that line from the refresh buffer onto the data bus.  Following the reading of each line the sequence is repeated, e. g., the line counter is incremented, its' count used to address the pointer register and the address contained in the pointer re-gister loaded into the refresh buffer address counter.
