Abstract: 1,200,273. Preparing aryl or vinyl esters. SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ N.V. 27 Nov., 1968, No. 56309/68. Heading C2C. A method of producing an aryl or a vinyl phosphonic acid ester, an aryl or a vinyl phosphinic acid ester, or an aryl or a vinyl phosphine oxide, or a mixture containing at least one such compound, comprises reacting a compound R(Hal) n  where Hal is halogen, R is an optionally substituted aryl or vinyl group and n represents 1 or 2, with a trialkyl phosphite, an alkylalkylene phosphite, a dialkyl-phosphonite, or an alkyl phosphinite, optionally in the presence of a solvent, at a temperature between 50‹ and 250‹ C. in the presence of catalytic quantities of a nickel halide and in an inert gas atmosphere. The term "aryl" includes hetero aryl compounds e.g. thiophene. The nickel halide is preferably dried before use and an amount between 0À1 and 20 mol. per cent with respect to aryl or vinyl halide is preferably used. In general, temperatures between 130‹ and 200‹ C. are used, and the reaction may be carried out batchwise or continuously.

Title: Brake control apparatus
IPC: B60T15/04
Filed: 1967-12-13
Abstract: 1,210,685. Compressed-air braking systems. COMPAGNIE DES FREINS ET SIGNAUX WESTINGHOUSE. 13 Dec., 1967 [23 Dec., 1966], No. 56620/67. Heading F2F. Brake control apparatus includes means to selectively generate fluidic pressure pulses, and means to apply the pulses to means responsive to them, to gradually modify a fluid pressure level which determines the degree of application of the brakes. For a normal brake application, as shown, a push-button valve 6 is operated to admit pressure to the input 5 of a fluid oscillator OS which produces pulses at its output 4. These are applied to an input 2a of a distributor 2 which vents the brake reservoir 1 to the atmosphere for the duration of each pulse. The brakes are thus gradually applied for as long as the pushbutton 6 is depressed, and a bi-stable device BD is held in a state inhibiting emergency brake release (see below). For normal release of the brakes, a similar push-button 9 is operated to cause a second fluid oscillator OD to apply pulses to a second input 2b of the distributer. The brake reservoir 1 is then recharged periodically from the main reservoir (not shown) via a reducing valve 3, and a second bi-stable device BS is held in a state inhibiting emergency brake application. The latter is initiated by a pushbutton valve 12 which admits fluid to input 11 of the bi-stable device BS and changes it to its other state when it delivers a steady pressure to the input 2a of the distributer. The reservoir 1 is then vented continuously to the atmosphere even though button 12 is released. As long as button 12 is pressed, fluid is also admitted to the oscillator OS via a one-way valve 13 and to the bi-stable device BD, augmenting the effect of bi-stable device BS and inhibiting brake release. Emergency braking is stopped by operating button 9 or 17. The latter sets the bi-stable device BD and a further bi-stable device BDS, the former operating oscillator OD as above and the latter providing a supplementary pressure to valve 3 to accelerate recharging of the reservoir 1. The valve 3 also supplies a timing reservoir 23 through a choke 24, and when this is recharged it resets the bi-stable device BDS. If not all the above functions are required, some or all of the bi-stable devices can be omitted. A further control may be provided on the distributer 2 to vent the reservoir 1 to the atmosphere if the supply to the oscillators and bi-stable devices should fail.

Title: Adjustable Spool

Abstract: 1,192,713. Adjustable spools. INTERNATIONAL BUSINESS MACHINES CORP. 29 Nov., 1968 [10 Jan., 1968], No. 56888/68. Heading B8M. An adjustable spool 11 comprises a hub member 15 rigidly connected to shaft 10. A plurality of resilient axial members 13 are secured at one end to hub 15. Each member 13 has a radial shoulder surface 25. A dished member 33 is journalled about a reduced diameter end 30 of shaft 10. The periphery 35 of dished member 33 abuts shoulders 25. The concave side of dished member 33 faces hub 15. As the dished member central portion 34 is moved towards hub 15 by moving lever 37 downwards so causing camming surfaces 40 to engage with dished member 33, the surface 35 urges the distal ends of members 13 radially outwards. In this condition the exterior winding surface 20 has a slight crown 49 at the axial mid-point of the spool. This arrangement ensures the uniform accumulation and retention of wound convolutions.

An annular air distributor 14 ensures turbulent air flow over the container surfaces. Alternatively (Fig. 1, not shown) the container may be heated inside a temperature-controlled tubular electric heater, being put in at the top and resting on spring claws or grate rods (3) until it is sufficiently reduced in size to fall off the claws or grate rods. Alternatively a gas-fired chamber may be used.

Abstract: 1,155,139. Telegraphy. INTERNATIONAL STANDARD ELECTRIC CORP. 22 Dec., 1966 [27 Dec., 1965], No. 57379/66. Heading H4P. A circuit for use at a subscriber's private exchange and which can be automatically connected to a switching system (e.g. the telex network) includes a main register for assembling and disassembling digital signals, a control register for establishing a mode of operation, a timing register, and a control unit interconnecting the registers and controlling the automatic connection. The circuit can pass dial pulses from the subscriber to the switching system, but ignores dial pulses from the switching system because these have already set up the connection to the subscriber. The operation of the circuit is generally similar to that described in Specification 1,088,341. The various input and output lines are scanned sequentially. When a line is scanned the control logic causes operation in the appropriate one of the following modes: (1) start-stop telegraph signals are transmitted or received either on a line connetted to the switching system or on a line connected to another terminal on the subscriber's private exchange; (2) dial pulses or continuous mark are transmitted to the switching system; (3) an idle signal is transmitted to another terminal on the exchange; (4) switching system control pulses are transmitted or received on the line connected to the switching system. The main register assembles a complete character received from the line and disassembles a complete character for serial transmission. The control register causes transmission or reception of start-stop data, control signals, and dial pulses. The timing register determines when particular actions are required.

Abstract: 1,268,800. Transistor relay operating circuits. ENGLISH ELECTRIC CO. Ltd. 15 Dec. 1970 [16 Dec., 1969], No. 61194/69. Heading H3T. A relay coil RL1 is controlled by transistor circuitry such as TR1 to TR4 and draws its initial turn-on current from a capacitor C1 which is charged by the input signal I to be monitored by the said circuitry, an external supply B1 being then connected to the relay, the circuitry, and the capacitor via the contact RL1/1. The capacitor C1 voltage is determined by Zener diodes D8, D9, being held charged from the input current I by means of a diode bridge D1-D4 and a resistor R2. If the input I exceeds its given limit, a diode D6 conducts when Zener D7 voltage is exceeded and turns off TR1. This allows the anti-interference capacitor C3 to charge and eventually turn on the bi-stable pair TR2, TR3, which turn on TR4 to energize RL1 coil. The external supply B1 now holds RL1 operated for as long as TR4 is held on by the excessive input current I. A further relay RL2 is simultaneously operated. Zener D5 protects the circuit against excessive input levels.
