Patent GB-1577039-A (GB)
Title: Valve system for the sequential control of two throttle valves
IPC: F24F1/01
Filed: 1977-02-24
Abstract: The control device has two throttle flaps (20, 25), one being intended for shutting off a heating device (9) and the other for shutting off a cooling device (6). The actuation of the two throttle flaps (20, 25) is carried out by a common power source via actuating rods, on which stops are located. These actuating rods act with their stops on arms which are connected in a rotationally fixed manner to throttle-flap shafts (19, 24). The design is such that one actuating rod can carry out an idle stroke in one direction and the other actuating rod an idle stroke in the other direction. This makes it possible to produce a simple, cheap control device which is not susceptible to faults. <IMAGE>

Title: Improvements relating to hydraulic servo systems
Inventor: MIDGLEY PETER JOHN
IPC: F15B5/00
Filed: 1965-02-24
Abstract: 1,092,997. Fluid-pressure servomotor systems. BRITISH AIRCRAFT CORPORATION (OPERATING) Ltd. March 15, 1966 [Feb. 24, 1965], No. 7905/65. Heading G3P. [Also in Division G1] A hydraulic servo control system comprises a control device of the jet and flapper type in which a gyroscope is directly connected to the flapper. The output signal of the gyroscope 1 moves a lever.2 about its pivot 3 to cause the lever to vary the back pressure of a jet or nozzle 7 supplied via a restriction 8, such pressure variation being communicated via line 10 to a relay valve as described below. The movable cylinder 5 of a dashpot is connected via spring 4 with arm 2" of lever 2 and serves to make the movement of the lever proportional to the time integral of the signal from the gyroscope. The  movable cylinder 12 of a stabilizing dashpot is directly connected to arm 2", and a spring 14 adjustably loads arm 2'. Opposite sides of the fixed pistons 5', 12' of the dashpots are interconnected by restrictions 6, 13 which may be of any of the forms indicated in Figs. 2a-d, (not shown). The relay valve Fig. 3a (not shown) comprises a piston having spaced lands 53, 54, a high-pressure inlet 25, a drain port (26) and an outlet 27 connected to a power device (Fig. 4). The signal in line 10 acts on land 53 and the outlet 27 communicates with land 54 via restriction 56. In the alternative relay valve of Fig. 3b (not shown), land (53') has a central extension (31) acted on by the signal in line (10), and the annular area of land (53') is acted on by a further signal in line (30). Land (54') abuts a spring (32) carried by a piston (34) which latter is mechanically movable to introduce another input signal. The power device comprises a pilot valve 67, 37 and a piston 65, 42, the pilot valve controlling communication between larger annular chamber 40 above piston 65 and either exhaust 41 or input 127. If the input signal from the relay valve increases, valve head 37 moves downwardly against spring 36 and admits the new signal pressure to chamber 40 thereby moving the piston downwardly until valve 37 is reseated. In the practical embodiment of Figs. 5-7 (not shown), the gimbal shaft (3) itself co-operates with the nozzles (7), the shaft being provided with flats for this purpose. The end of shaft (3) carries two leaf springs (4') the free ends of which carry pistone (73) supported by diaphragms (74), opposite sides of the latter being connected via capillary tubing. Pistons (73) thus form the movable elements of a pair of integrating dashpots. A vane (2) carried by shaft (3) is movable between stops (11) in a chamber (12) to form the stabilizing dashpot, opposite sides of the vane being connected via a restriction of the type shown in Fig. 2d, which latter has an arrangement of four orifices forming a bridge network which gives a linear relationship between rate of displacement and applied force and a pressure drop independent of viscosity.

Title: Improvements relating to the production of polymerised vinyl products
IPC: C08F36/04
Filed: 1944-08-25
Abstract: Vinyl compounds are polymerized or copolymerized in aqueous dispersion in the presence of (a) free or combined sulphur dioxide dissolved in the aqueous medium and oxidizable by free oxygen therein; (b) oxygen acting to oxidize the sulphur dioxide, and (c) a substance acting to catalyse the oxidation and thereby promote the polymerization.  Vinyl compounds specified are methyl methacrylate, acrylonitrile, vinyl acetate, vinyl chloride, vinyl ethers, butadiene, styrene and its homologues and vinyl naphthalene and its homologues.  The forms of free or combined sulphur dioxide may be those described in Specifications 582,134 and 582,327.  The oxygen may be introduced into the dispersion indirectly, by way of a vapour space, e.g. using nitrogen containing 0.1 per cent of oxygen; or directly by the use of a preformed aqueous solution of oxygen or air, by nascent oxygen produced electrolytically, by chemical action between the free or combined sulphur dioxide and hydrogen peroxide, ethyl benzene peroxide, benzoyl peroxide or tetrahydro-naphthalene peroxide or a water-soluble salt of copper, manganese, iron or cobalt in the - ic state, which also possesses the property of catalysing the oxidation.  This salt may be present as an impurity in any of the components of the dispersion.  Emulsifying agents, e.g. sodium, potassium or ammonium soaps, or lauryl sulphate and protective colloids, e.g. gelatine, methyl cellulose, polyvinyl alcohol, saponin or gum arabic may be present.  The process is preferably conducted by adding the vinyl compound at a controlled rate to the rest of the components of the dispersion with stirring.

Abstract: 1,007,821. Measuring resistivity. STANDARD TELEPHONES & CABLES Ltd. March 1, 1963, No. 8321/63. Heading G1U. [Also in Division H3]. A resistivity meter comprises a tuned circuit 2 to which is coupled the sample to be measured, which may be a semi-conductor; a swept frequency oscillator 3 coupled to the tuned circuit (through an attenuator 4) and a peak reading voltmeter 9 coupled to the tuned circuit by means of a diode detector stage 7 so that the peak voltage developed in the tuned circuit by the oscillator is detected and measured. The oscillator is swept through its frequency range by the saw tooth output of an astable multivibrator 5 (see Division H3),the frequency of which is reduced during that period when the voltage developed in the tuned circuit rises above a predetermined level. This arrangement is so that the test circuit is not swept through its resonant frequency so quickly that the peak reading voltmeter fails to operate correctly.
