Patent GB-2078048-A (GB)
Title: Radar apparatus
IPC: G01S7/292
Filed: 1981-06-01
Abstract: Radar apparatus has a non- resonant linear array antenna 1 that is supplied with signals at two different frequencies f1,f2 such that two beams are propagated at different angles  alpha 1, alpha 2. As the antenna 1 is rotated about its axis 11 one beam leads the other and receives echo signals in respect of the same location prior to the other beam. The echo signals in respect of the two beams are supplied to a comparator 30, the signals from the leading beam being delayed so as to be supplied to the comparator simultaneously with the signals from the other beam. The comparator 30 passes, to a display 3, only those signals that are within predetermined limits of one another, rejecting those signals that change substantially between the leading and the other beam, and which are thereby in response to transient phenomena. <IMAGE>

Title: Data demodulator for a direct frequency modulated signal
Inventor: MARSHALL CHRISTOPHER BRIAN
IPC: H04L27/152
Filed: 1982-07-07
Abstract: A data demodulator for a direct frequency modulated signal such as an FSK signal used in quasi-synchronous signalling systems, for example paging systems, is of the type in which an input signal 10 of frequency fc +/-  DELTA f is mixed 12, 14 with quadrature components of frequency fc from local oscillator 16 to give signals A, B in +/-90 DEG  phase relationship, and derives therefrom quadrature output signals at E, G for a positive frequency deviation, or quadrature output signals at F, H for a negative frequency deviation, by means of 90 DEG -phase shifters 24, 26 (and adjustable phase shifters 28, 30) which give an in-phase pair of signals (B', C or A', D and an anti-phase pair of signals (A'D or B'C) in quadrature to the in-phase pair of signals (A'D or B'C) in quadrature to the in-phase pair, and means for adding 32, 34 and subtracting 36, 38 each signal pair to give signal cancellation/reinforcement. The resulting outputs E,F,G, H are amplitude detected 40-46 and quadrature pairs of signals K,M or L,N are added 48, 50 to provide a detection signal at R or S that never falls to zero. A final subtraction stage 52 provides a simple output T. <IMAGE>

Patent GB-2107830-A (GB)
Title: Valve plate for an alternating compressor
Inventor: BALMA ANTONIO
IPC: F04B39/10
Filed: 1982-08-24
Abstract: Valve plate 5 for an alternating compressor is constructed in press- cast metal alloy and has the sealing seats 8 of the valves (on which the valves are directly assembled) formed directly upon it. The valve plate 5 requires mechanical working only at the sealing seats, and an effective cooling of the seats 8 of the valves results due to the material continuity of these with the mass of the plate 5 through which the heat is removed. Cooling is further enhanced if plate 5 is provided with a cooling fin 6 as illustrated. Furthermore, the plate is preferably shaped so as to reduce to a minimum the dead spaces at the top of the cylinders of the compressor. <IMAGE>

Title: Sifting procedure and apparatus
Inventor: RISSANEN VILPPU UOLEVI
IPC: B07B1/52
Filed: 1983-04-06
Abstract: In a sifting procedure for treating materials difficult to sift, in which any one component of the material tends to become adherent to the surface of the sieve, e.g. a mixture consisting of sunflower seeds and of other kinds of inflorescence material accompanying them, the adhesion problem has been solved by using a brush roll (3) disposed against the surface of the sieve e.g. a rotatable drum sieve (2), in the manner that the brush roll is rotated about its own axis (4) and, at the same time, the surface of the sieve and the brush roll are displaced in relation to each other. Hereby the brush roll (3) sets the material to be sifted in motion and, on the side, detaches material that has become adherent to the surface so that the sieve is kept permeable. To the purpose of moving the material to be sifted, introduced at one end of the drum sieve (2), during the sifting process towards the opposite end of the sieve, the brush roll (3) may be provided with a helical thread moving the material to be sifted. <IMAGE>

Title: Automatic control of a cooling system for a turbocharger
Inventor: TANAKA HIDEYUKI
IPC: F01P7/08
Filed: 1983-05-13
Abstract: A turbocharger is cooled by a cooling fan (18) under the control of control means. The control means (2, 3, 4, 6 and 7) monitors the temperature of the turbocharger housing sensing by a temperature sensor (1), and detects a time when an ignition switch of the engine is turned off. By so doing, the control means actuates the cooling fan for a predetermined time interval starting from a time the ignition switch is turned off, if the sensed temperature is equal to or higher than a predetermined temperature. The temperature of the exhaust gases of the engine may be sensed instead of the temperature of the turbocharger housing. The time interval may be made dependent on the initial temperature of the turbocharger. <IMAGE>
