Title: Communications system
IPC: H04B1/10
Filed: 1977-10-12
Abstract: 1534380 Adaptive array; communications system MOTOROLA Inc 12 Oct 1977 [22 Nov 1970] 42487/77 Headings H4A and H4L The present invention relates to a PSK communications system using null steering adaptive array receiving apparatus, Fig. 2, wherein automatically forming the reception lobe of the array on an A/C 10, Fig. 1, with a null in the direction of a jammer A/C 12, and a maximum in the direction of the communicating A/C 11, is characterized by the transmission of a lower power QPSK signal from A/C 11, as well as the PSK communications signal, and the generation at A/C 10 of a reference signal being a replica of the PSK signal, from the demodulation of the QPSK signal and the use of said reference signal in the feed-back path of the adaptive array to give the maximum in the lobe. The signal from each antenna is split (25) into quadrature components which are so amplitude weighted (32, 37) that the output of a summer 40, receiving all the weighted quadrature pairs equals the reference signal for the maximum (or zero for the interference null). The QSPK (b), Fig. 3 has its modulation delayed by one bit from the information modulation on the PSK signal (a). The quadrature relationship of the carriers is shown at (c). The QSPK signal is demodulated by a phase demodulator 45 using the output of a VCO 46 controlled, phase locked loop fashion, by the output of the demodulator. The modulation ouput of the demodulator, now in phase with the information modulation, is PSK modulated (47) onto the output of the VCO to give the replica signal for application to comparison circuit 41 receiving the output of summer 40.

Abstract: 1,020,419. Tunnel diode logic circuits. INTERNATIONAL BUSINESS MACHINES CORPORATION. Oct. 19, 1964 [Nov. 1, 1963], No. 42531/64. Heading H3T. A logic circuit comprises the series connection of two tunnel diodes 5, 6 arranged for monostable operation, an input circuit 21 arranged to apply a signal across both diodes and a second input circuit 22 arranged to apply an input signal across diode 6 only, diode 6 having a higher peak current than diode 5. A third tunnel diode 7 is preferably connected in series with diode 6. Each diode is normally in its low voltage state, inductors or delay lines 15, 16, 17 being provided so that the diodes may be operated in a monostable manner by pulses applied to appropriate input terminals. A pulse at 22 or 23 may be arranged to set tunnel diode 6 to its high voltage state for a period depending on the transit time of delay line 16. Diode 6 becomes restored to its stable state by successive reflections at the end of delay line 16 which results in a staircase waveform being present at 50. The operation of diode 6 may be inhibited by pulsing terminal 21 so that diode 5 is set to its high voltage state. Alternatively the values of resistors 32, 33 may be selected so that the circuit provides an AND or majority function.

Abstract: 1478543 Synchronous box-making line UNITED STATES BOX CORP 3 Oct 1974 [5 Oct 1973]  42877/74 Heading G3N A line of box-making machinery includes an apparatus for synchronizing the operation of a blank cutting and web-feed mechanism 30 with the operation of a box-forming mechanism 40 independent of fluctuations in the speeds of respective independent motors, by which the mechanisms 30, 40 are driven from a nominal speed. The synchronizing apparatus comprises first, second and third cams (66, 70, 82) Figs. 4 and 6 (not shown) and first, second and third switches (74, 78, 94), Figs. 4, 6 and 7 (not shown) actuable thereby. The first and second cams (66, 70) are rotated together on a common shaft by the box-forming mechanism motor so that they each perform a single revolution for every cycle of the box-forming mechanism and actuate the first and second switches (74, 78) during different portions of each said cycle. The third cam (82) is rotated by the cutting and advancing mechanism motor so that it performs a  single revolution for every cycle of the cutting and advancing mechanism 40 and actuates the third switch (94) during a portion only of said lastmentioned cycle. When the required degree of synchronization exists between the mechanisms 30, 40, the first switch (74) is closed, the third switch (94) is opened and the second switch is opened successively to permit continuous running of the cutting and advancing mechanism motor (154), Fig. 7 (not shown) which is in a circuit with the switches (74, 78, 94). However, if the second and third switches (78, 94) happen to be in an open state simultaneously, the motor (154) is de-energized and subsequently energized in synchronism with the box-forming mechanism motor by closing of the switch (74). Further cams (86, 90) Fig. 6 (not shown) are rotated with the third cam (82) and actuate switches (98, 102) simultaneously with actuation of the third switch (94) to energize independent motors for a web imprinter 26 and a web die press 28. The third cam (82) is arranged to actuate the third switch (94) as the cutter 36 operates on the web. The web is drawn from a roll 12 and around a dancer roller 25 which is mounted on the free end of a pivotal rod 18, by feedrollers 32. Unwinding of the web from the roll is controlled by a clutch actuated by engagement between switches 50, 52 and the rod 18. Additional switches 56, 58 which are in a circuit with the cutting and advancing mechanism motor (154), cause de-energization of this motor when they are engaged by the rod 18.

Title: Process for treating raw dressed poultry carcasses with basting fat
IPC: A23L13/70
Filed: 1966-09-27
Abstract: 1,129,689. Fatted, dressed poultry carcass. ARMOUR & CO. 27 Sept., 1966 [1 Oct., 1965], No. 43044/66. Heading A2E. A raw, dressed poultry carcass, or part thereof, is rendered self-basting by introducing into the carcass below the skin an added body of edible fat and forming flow passages through the skin through which the edible fat under cooking temperatures flows on to the skin. The passages may be made by passing fat-injecting needles of specified size down through the skin and muscle (breast and leg) portions of the carcass; since the skin moves freely when it is engaged by the needles, the passages in the skin and muscle portions are misaligned so that there is no tendency for the fat to exude on to the skin prior to the cooking. Alternatively, the fat may be injected under the skin through the body cavity of the carcass and the necessary perforations made by the housewife with a fork prior to placing the bird in the oven. The fat may carry flavourings and fine particles of polyphosphates in suspension, air, nitrogen or carbon dioxide being incorporated in the fat to assist in suspending the particles. Poultry: turkeys, chickens, geese, ducks, also pheasants. Edible  fats: butter, butter oil, lard, margarine, corn oil and cottonseed oil. Polyphosphates: any non-cyclic polyphosphoric acid salt of sodium or potassium having a ratio of H 2 O to P 2 O 5 , of between 0.9 : 1 and 2.0: 1; sodium or potassium tripolyphosphate, sodium hexametaphosphate, and tetrasodium or tetrapotassium pyrophosphate are particularly mentioned. Flavourings enhanced butter flavour based on lipolysed cream.
