Abstract: 1396260 Digital transmission; phase modulation LICENTIA PATENT-VERWALTUNGS GmbH 12 Oct 1973 [28 Oct 1972] 47770/73 Heading H4P In a digital phase modulated transmission system, particularly through a satellite whereby each station is allocated a cyclic time slot, in addition to a 4 phase coherent demodulator at each receiver extracting information content, to quickly identify starting and sync. code words, a 2 phase non-coherent demodulator is employed. This identifies the starting or address code and delivers an actuating signal. The non-coherent demodulator may be of a type in which one signal is delayed one bit place and compared with the following bit. The 2 phase demodulator enables more rapid recognition of the starting code as a carrier does not have to be derived; the bandwidth of the four phase demodulator can also be reduced. On reception incoming signals may be changed to an intermediate frequency. The power used to transmit the starting code may be doubled thus reducing possibility of error.

Abstract: 1316371 Process for purification of gypsum GIULINI GmbH Gebr. 8 Oct 1970 [8 Oct 1969] 47925/70 Heading C1A Impure gypsum containing inorganic or organic, water-soluble or water-insoluble impurities is purified by subjecting an aqueous suspension of the gypsum to hydro separation at a pH of not more than 2À5 in the presence of a water-miscible or water-immiscible organic reagent. The hydro separation is preferably effected at a temperature of 5‹ to 60‹ C. at a gypsum slurry concentration of from 50 to 650 g. of dry gypsum per litre of suspension. The hydro separation process may be carried out using water passing either in the same direction or counter to the flow of the aqueous gypsum suspension. Examples of suitable hydro separators are upcurrent bowl classifiers, decanting centrifuges, flotation devices, concentrators, zig-zag and countercurrent washers. Suitable water-miscible organic reagents include oxygen containing compounds such as watersoluble aromatic, aliphatic or cyclic mono- or polyhydric C 1 -C 6  alcohols, water-soluble polyalcohols, sulphonates or sulphates, ketones, ethers, nitro compounds and methylated polyalcohols, e.g. methyl celluloses. Examples of the water-immiscible organic reagents are oxygen-containing water-immiscible-compounds such as aliphatic, aromatic and cyclic mono- or polyhydric C 4 -C 20  alcohols and aliphatic, aromatic or cyclic C 6 -C 20  hydrocarbons. The pH of the aqueous gypsum suspension is adjusted by the addition to it of from 0À2 to 20 kg. of strong acid (based on 100% acid) per 1 m<SP>3</SP> of suspension. The pH is preferably adjusted by adding sulphuric acid, but other acids such as nitric or monochloroacetic acid may be used. The process is carried out in one or more sequentially connected or parallel connected stages.

Abstract: 1,181,608. Ultrasonic inspection devices. COMMISSARIAT A L'ENERGIE ATOMIQUE. 10 Oct., 1968 [27 Oct., 1967], No. 47994/68. Heading H4D. An ultrasonic pulse-echo method for indicating in two separate channels the presence of flaws in the inner wall or outer wall of a very thin tube comprises rotating the tube (which is air-filled) about its axis in a tank of water, directing the beam of a single transmit/receive transducer whereby the angle of incidence of the beam on the tube is such that an outer-wall flaw gives a relatively high amplitude singleecho signal and an inner-wall flaw gives a relatively low amplitude damped train of echo signals, applying the echo signals for display against an oscilloscope time-base via an amplifier, maintaining the amplifier gain relatively low in that time period containing the outerwall flaw echo, maintaining the amplifier gain relatively high in the later time period containing the inner-wall echo train, and selecting the outer-wall echo and one of the inner-wall echoes by means of two time-gates. The gain control ensures that the flaw echoes can be separated, on an amplitude basis, from fixed interfering echoes arising from, e.g., the wall of the water tank.

Abstract: 1,275,000. Change-speed control. NISSAN MOTOR CO. Ltd. 13 Oct., 1970 [14 Oct., 1969], No. 48656/70. Heading F2D. Liquid servo pressure 84, engaging ratioselecting friction clutches and brakes in a torqueconverter-driven automatic transmission on a motor-vehicle, is controlled by a pressureregulating valve 71, subject to load-augmentation by pressure in a line 94 controlled by throttling an exhaust-nozzle 106 by a flap valve 107, actuated by an electromagnet coil 108, energized by a voltage signal proportional to output speed, modified by a second signal which includes the gear-ratio established in the transmission and is such that the output voltage signal is proportional to the torque-converter turbine speed up to a predetermined value (the coupling point), above which it is maintained constant for a given engine torque. Such a signal represents turbine (i.e. gear input) torque for a given engine torque, and the latter para-  meter is also included by supplying the throttled [ine 94 through a pressure-regulator valve 73, loaded at 104 by engine intake depression. The pressure augmentation is cancelled during gear shift for a timed interval. Shift circuit, not described,-responds to output speed, engine torque (throttle setting) engine temperature and road gradient, the last named displacing the shift points to reduced speeds. Servo pressure control.-The voltage signal actuating the flap-valve 53, for control of loading of the main pressure regulator valve 71, is derived from a circuit, Fig. 5, which receives signals 13, representing output speed; T1, T2, gear ratio; a power supply 51, and stabilized voltage supply 49. 'Establishment of first ratio in the transmission produces a voltage signal at T2, zero at T1, so that a second transistor 35 conducts and a first, 30, is non-conductive, which applies a voltage from 13, determined by resistors 33, 47 to the base of an output transistor 43, with amplifier 44, applying voltage to the flap valve 53. In second ratio T1 receives a voltage signal and T2 zero, the second transistor 35 is now non-conductive, the first, 30, conductive, so the transistor base potential 43 is determined by resistors 37, 39, 47. In third ratios both T1 and T2 receive voltage signals, and base potential 43 is determined by resistors 40, 41, 47. These potentials are arranged to be in the same ratios as those of the transmission, so that output potential-at 53 is proportional to turbine speed until that speed reaches a predetermined value, above which the signal 53 is maintained constant by the stabilized voltage supply 49. Fig. 6 (not shown) introduces into the Fig. 5 circuit a mono-stable multivibrator, triggered at .gear-shift by a negative signal (T3), which cuts off the voltage signal supply to the base of the transistor 43 for a predetermined interval during the shift.
