Abstract: 1500289 Secondary radar; transponder systems RCA CORPORATION 8 May 1975 [3 June 1974 (2)] 24404/74 and 24405/74 Headings H4D and H4L An interrogator or transponder for a system in which the interrogator utilizes a homodyne receiver, has provision for changing the phase of the reply signal so as to prevent the maintainance of unwanted nulls in the output of the receiver when the interrogating and reply carriers are in phase quadrature. As shown in Fig. 1, a vehicle location system comprises an interrogating unit 10 located on the vehicle and a plurality of remote units (transponders) 14 mounted on sign posts. An unmodulated carrier from a transverse electron oscillator 18 is coupled to a directional antenna 24 and received by an antenna 32 in the remote unit 14. The carrier is modulated by a digital signal indicative of the location of the remote unit 14, from logic 39 and is retransmitted to the interrogator unit where it is combined by means of a homodyne mixer 28 with the unmodulated carrier from 18. Mixer 28 provides a signal proportional to the product of the two amplitudes and the cosine of the phase angle. When the distance between the vehicle 10 and the remote unit 14 is such that the phase angle is 90 degrees, a null appears in the output of mixer 28. This is minimized by periodically changing the phase at 44 by means of a square wave oscillator 46. Alternatively, the phase change may be accomplished in the interrogator 10 and may be initiated only in the presence of a null. The frequency of the phase changing oscillator 46 may be greater than or less than the digit rate from logic 34. In Figs. 5-7 (not shown) the digital data from logic 39 may be frequency-shift keyed on to the carrier in remote unit 14. Fig. 7 (not shown) relates to a block diagram of the device 31 and comprises a buffer register feeding a cascade of latches which provides required outputs to a two-way radio so that the position of the vehicle can be continually recorded by a central station.

Title: Analog to Digital Converter
IPC: H03M1/00
Filed: 1968-05-23
Abstract: 1,161,549. Analog/digital converters. INTERNATIONAL BUSINESS MACHINES CORP. 23 May, 1968 [27 June, 1967], No. 24577/68. Heading G4H. An analog input signal V x  is applied for a fixed time interval to an integrator 28 (Fig. 1), which is then discharged by applying successively reference signals of predetermined amplitude but of opposite polarity to the signal V x  until the output of the integratator 28 reaches a predetermined level, the time taken for the integrator to reach this level being measured to give a digital indication of the signal V x . In the embodiment described with the output V o  of the integrator 28 initially at zero, a comparator 32 delivers an output signal 36 which via OR gate 302 (Fig. 5) and flip-flops 306, 308 opens switch 26 and closes switch 22 so that the signal V x  is applied to the integrator. The output of NOR gate 322 goes to " 0 " so that clock pulses are accumulated in counter 12. When it is full the output of OR gate 320 goes to " 0 " so that flip-flop 312 is reset to open switch 22 and flip-flop 316 is set to close switch 24 through which the first reference signal V r1 , is fed to integrator 28. Clock pulses are accumulated in counter 12 until the output of integrator 28 drops to a level V t  detected by comparator 30 which via OR gate 300 sets flip-flop 304 so that flip-flop 316 is reset to open switch 24 and flip-flop 308 is set to disable via NOR gate 322 counter 12, enable counter 14 and close switch 26. The second reference signal V r2  is fed to integrator 28. When the output of the integrator drops to zero, detected by comparator 32, the count in counter 14 is terminated. Any carry pulses are transmitted from counter 14 to counter 12 by the output of NOR gate 318 temporarily going to " 1 " to enable via NOR gate 322 counter 12 to receive one clock pulse. The contents of counters 12, 14, which hold the higher and lower bits respectively of the digitized output signal, are fed to a magnetic core store 42. Bipolar input signals may be digitized by including circuitry for detecting the polarity of the input and adjusting the polarity of the reference signals. More than two reference signals may be used, the number of comparators and switches being correspondingly increased.

Abstract: 793,043. Hand knitting-machines. SKENE, R. VON. Aug. 27, 1954, No. 24904/54. Class 74(2). The cam lock 8 of a flatbed latch-needle machine carries a yarn guide 30 the eye of which is formed with points 46 of which the leading one opens the needle latches, for yarn reception, as the lock traverses the bed. Each point 46 is bevelled from underneath, so that misplaced needles are pressed back into their grooves. A straight part 54 of a blade 31, also carried by the cam lock, lies closely beneath the needles 3 and prevents the stitches being carried forward as the needles advance. Obliquely upturned ends 53 of the blade 31 assist in preventing accidental cast-off of stitches. The front ends of the needle tricks are deepened at 5, Fig. 3, so that by tilting the needles they may be withdrawn without removal of the needle bar 4. Figs. 4 and 5 show other formations of needle trick to the same end. The stitch cams 19 are hinged about pivots 20, so that the leading cam is lifted and rendered inoperative by the needle butts, as they pass under it, only the lagging cam being effective and, to vary the stitch length, the cams are adjustable along their pivots by unscrewing a handle 12 and partly rotating a lever 10 to move a plate 15 bearing lugs 21 which engage the outer ends of the hinges of the stitch cams. Rib knitting may be carried out by introducing a second set of latch needles 34, fixed in a bar 33 movable up and down, to knit, by a lever located in any one of three positions by a ball catch. That side of the upper edge of a plate 37 which faces the needles. 34 is left square to assist knockover. The other side is rounded to allow the fabric to slide down easily under the action of take-up weight. The needle bar 33 can be moved out of the way for plain knitting. As the lock moves beyond the last needle at the end of a traverse, a roller 59 drops off the needle shanks and, under the influence of its spring 67, the other end 68 of a lever carrying the roller clamps the yarn as it passes through a double loop 65, on its way to a tension take-up arm 56. To knit alternate plain and purl courses, the whole fabric may be reversed, face for face, between successive courses, by means of a comb 77, the hooked teeth 79 of which can be made to envelope the needle hooks and receive their loops, which are restored to the needles after the comb has been turned end for end. By making the pitch of the hooks twice that of the needles, loops may be transferred to adjacent needles, to form lace openings.
