Title: Process for the manufacture of derivatives of ethylene and homologues thereof
IPC: C07C29/66
Filed: 1928-05-31
Abstract: 292,066. I. G. Farbenindustrie Akt.- Ges. June 11, 1927, [Convention date]. Void [Published under Sect. 91 of the Acts]. Olefine oxides; chlorhydrins. - Gases containing olefines are treated to produce a mixture of olefine oxides which are then separated by fractional distillation. The gas, which may contain ethylene, propylene and butylene is treated with hypochlorous acid to form the chlorhydrins, which are treated with alkalies to produce the olefine oxides. In an example the chlorhydrins are distilled with milk of lime to produce the oxides and the oxides are distilled preferably under increased pressure to obtain the individual oxides.

Abstract: 980, 284. Comparing numbers. RADIO CORPORATION OF AMERICA. May 4, 1961 [May 26, 1960], No. 16282/61. Heading G4M. [Also in Division H3] A circuit capable of assuming three states and suitable for use in comprising binary numbers comprises, in series across a supply, a resistor, a first tunnel diode, a second resistor and a second tunnel diode, the arrangement being such that either one or the other or both of the tunnel diodes may be in the high voltage state. The Figure shows two tunnel diodes 40, 48 in series with respective resistors 42, 50 and biased from batteries 46, 54 by way of potentiometers 44, 56 and 52, 58. A reset pulse applied from source 60 together if desired with an oppositely phased reset pulse applied to point 92 will set both diodes to the high voltage condition. An input pulse at terminal 66 of one polarity will thereafter set one tunnel diode to the low voltage condition or of the other polarity will set the other tunnel diode to the low voltage condition. A larger input pulse of the correct polarity will switch the high voltage diode to the low voltage condition and the low voltage diode to the high voltage condition. The position of each diode and its corresponding resistor may be exchanged (Fig. 2 not shown). The input signal may be applied simultaneously with the reset pulse, in which case the output terminal 74 will take up a state corresponding to one the input, positive, negative or zero. Also two input pulses may be applied simultaneously in which case if they are both negative the circuit will switch in one direction both positive the circuit will switch in the other direction and if they are of opposite polarity the third state will be assumed. A plurality of such circuits may be used to compare two parallel multiple digit binary numbers.

Title: Improvements in or relating to electrical signalling systems

Filed: 1932-06-09
Abstract: 401,033. Electric signalling systems. FLOWERS, T. H., 60, Windsor Road, Palmers Green, London. June 9, 1932, No. 16290. [Class 40 (i).] Responsive apparatus which distinguishes between a pure signalling frequency and a range of frequencies, e.g. speech or noise, including that frequency comprises two parallel circuits which control relays R, S, Fig. 1, through transformers T1, T2 and thermionic valves V1, V2, one circuit being shunted by a condenser C and inductance L forming a circuit resonant to the signalling frequency f1, so that for this frequency S alone energizes and releases a normally operated relay T, while if other frequencies are present, both R and S energize and T remains operated. The other circuit may be shunted by a circuit resonant to a different signalling frequency /2, which when pure causes the energization of R only. The valves V1, V2 are provided with a capacity coupling between the anode and grid circuits, the A.C. component of'the anode current being fed back through condensers C1, C2 and rectifiers to make the grid potential more positive, thus increasing the anode current. The anode circuit relay may be caused to vibrate by means of a resistance connected across the condenser C3 or C4 by its operation, thus reducing the reactive effect sufficiently to release the relay.' The resonant circuit may be shunted across an additional secondary winding of the transformer instead of across the primary as shown. Fig. 2 shows an arrangement of relays for receiving three different frequencies X, Y, Z, corresponding to R, Fig. 1, .and responding to all frequencies except the signalling frequencies f1, f2, f3 respectively. P, Q, R are normally operated and are controlled by X, Y, Z so as to be released in pairs by the pure signalling frequencies. They may all be released by applying one of the signalling frequencies, followed by any other frequency, and they may be reoperated in different orders according to the order in which the signalling frequencies are cut off.

Title: Improvements in or relating to Vehicle Braking Systems
Inventor: WALKER FREDERICK JAMES
IPC: B60T8/38
Filed: 1966-04-15
Abstract: 1,181,963. Servo brake systems; valves. HARRY FERGUSON RESEARCH Ltd. 14 April. 1967 [15 April, 1966], No. 16556/66. Addition to 1,101,582. Headings F2F and F2V. In a vehicle according to any one of the claims of Specification 1,101,582, a pressureresponsive control valve 56a is interposed between the valve 14 and the servo-mechanism 11 to control fluid flow from the latter to the former subsequent to anti-skid operation to thereby control reapplication of the brakes. When the brakes are off pipe 56 is connected to the vacuum tank 10 and pipe 55 is connected to atmosphere. The vacuum in chamber 73  is the same as that in chambers d and c so that the atmospheric pressure always present in chamber b opens the valve. During normal brake application valve 56a remains open. During anti-skid operation valve 14 connects pipe 56 to atmosphere and pipe 55 to vacuum tank 10, the pressure in chamber 73 rises to an extent dependent on the time of operation of the rotary inertia device 12. Under slippery road conditions and consequently slow acceleration of the vehicle transmission chamber 73 is connected to atmosphere long enough for the pressure to rise above the predetermined vacuum level. The pressure in chamber c and the loading of spring k then close the valve which remains closed during the pressure rise, air flow being permitted through flap valve r. When the rotary inertia device again becomes inoperative the valve 14 again connects pipes 55 and 56 respectively to atmosphere and the vacuum tank. Withdrawal of air from chamber 73 is restricted as the valve 56a remains closed whilst air can only pass through a passage u or slots (q), Fig. 3 (not shown), thereby delaying reapplication of the brakes and permitting controlled braking suited to the slippery conditions. Connection 55a, which has a non-return valve 55b, assists the expulsion of air from chamber 72 during anti-skid operation. In modifications the vacuum servomechanism may be replaced by an hydraulic servo-mechanism and the anti-skid device may operate in response to changes in linear inertia.

[Class 37] In an induction type power or energy meter the inductance of the quadrature loop or other phase correcting device is adjustable to effect the required calibration or correction. The invention is described in relation to a watthour meter, Fig. 1 (not shown), whose quadrature loop 13 is embraced on one of its sides, as shown in Fig. 2, by a U-shaped block 14, Fig. 3, of magnetic material and calibration is effected by moving in or out as required a screw 16 in the slot 15.
