Title: Fluid flow control valve
Inventor: CUSI EDUARDO LUIS
IPC: G05D16/16
Filed: 1967-08-11
Abstract: 1,143,318. Valves. SARGO INTERNATIONAL CORP. 11 Aug., 1967, No. 37119/67. Heading F2V. [Also in Division G3] A valve comprises a closure 66 mounted on a stem 45, 63 actuated by a diaphragm 69 which partially defines a chamber 41 containing a liquid, a second chamber 52 serving as a liquid reservoir in communication with an actuating gas supplied through a conduit 5, 6, 7, and a liquid conduit 60, having a flow restriction 59 connecting the chamber 41 and 52. Flow of gas, e.g. steam, through the conduit 5, 6, 7 is controlled by a pilot valve 32 actuated by a diaphragm 37 and a spring 4. Upon a drop in pressure in the outlet of the main valve, connected to a tapping 25, the valve 32 is forced downwards to allow inlet pressure to flow through the conduit 5, 6, 7 and act on the liquid in the reservoir 50 to force it into the chamber 51 and act on the diaphragm 69 to open the closure 66. When the controlled fluid is steam, the liquid in the chamber 52 is condensate, which initially passes through the conduit 5, 6, 7. Condensate is also allowed to pass around the stem 66, 45 into the chambers 64 and 65. If the controlled fluid is a non-condensable gas, liquid may be added to the chambers 41, 52, 64 and 65. The control pressure signal at the tapping 25 may be supplied from a temperature sensitive transducer. The pilot valve may be actuated by a form of motion other than the diaphragm 37.

The system may be in the form of a closed ring and a plurality of links may be provided. Each transmitter may provide a unique code signal on intruder detection to assist in locating the intruder.

Title: Improvements in or relating to organosilicon compositions
Filed: 1959-11-04
Abstract: A heat-stable elastomer-forming composition comprises an essentially diorganopolysiloxane and from 0,001 to 8% by weight of the siloxane of a lanthanide rare earth metal (i.e. lanthanum, cerium, praeseodymium, neodymium, sarmarium, europium, terbium, dysprosium, holmium, erbium, thulium, ytterbium or lutemium) present as an oxide or hydroxide.  The siloxanes used consist primarily of R2SiO units, may contain R3SiO 1/2 and SiO2 units, and preferably have a R/Si ratio of 1,98 : 1 to 2,01 : 1 and terminal Si-bonded hydroxyl, alkoxy, vinyl or acyl radicals or hydrogen atoms, R being alkyl, alkenyl, acyl, aralkyl, alkaryl or halogenated hydrocarbon.  Fillers per se or modified with organosilyl groups, e.g. TiO2, Fe2O3, ZnO, asbestos and glass fibres, diatomaceous earth, crushed quartz and silica (fume, aerogel and precipitated) having a surface area greater than 50 m2/g, may be added.  The compositions may be cured (i) by exposing them to X-rays, g -rays or to ultra-violet light, (ii) by heating with organic peroxides, e.g. benzoyl-, dichlorobenzoyl- and di-t-butyl-peroxides and t-butyl perbenzoate, or (iii) at room temperature, by mixing an acid-free diorganopolysiloxane and an organic silicate in the presence of a metal carboxylate, as disclosed in Specification 764,246, or in a modification by using a "Cellosolve" (Registered Trade Mark) silicate with the carboxylate, as disclosed in Specification 844,128; by mixing a hydroxylated diorganopolysiloxane with an organohydrogen siloxane as disclosed in Specification 804,199; or by exposing certain acyloxy-terminated diorganopolysiloxanes to moisture, as disclosed in Specification 862,576.

Title: Torque limiters of the friction type
IPC: B25B23/159
Filed: 1974-08-28
Abstract: 1471077 Torque-limiting wrenches AGENCE NATIONALE DE VALORISATION DE LA RECHERCHE 28 Aug 1974 [30 Aug 1973] 37671/74 Heading B3N [Also in Division F2] A torque limiting device such as a wrench comprises inner and outer members M, B, Figs. 2 and 3 and, for transmitting limited torque between the two members in both senses of applied torque, at least one friction member S which frictionally engages one of the members and is resiliently interconnected at a first location with the other member via a torsion bar 2 and is, at a second location spaced circumferentially (or helically) from the first portion, in abutting engagement with a stop P on the other member (or is secured to the other member). The torsion bar 2 may be fixed to one end of the inner member M by a pin G and provided with a square section 5 for driving a bush adapted to the dimensions of a nut or screw to be driven. When the outer member B is turned by applying a bar through a hole 6 the torque is transmitted through friction shoes S to the torsion bar 2 which is preset by selecting the required hole for the pin G. Stops Q of the head TE of the torsion bar pass through slots J of the member M and the friction shoes S are compressed (and therefore urged outwardly) by the torsion bar between its stops Q and the stops P provided on the member M. In Fig. 4 the friction member is constituted by a helicoidal tape which when the torsion bar is preset expands against the wall of the outer member B. If desired, the helicoidal tape may be disposed on the outer surface of the member B to allow cooling by fins or liquid coolant. In Figs. 5 and 6 (not shown) the friction member is constituted by a tube (7) cut to form three helicoidal tapes, the ends (9, 10) of the tube being provided with various holes (13, 15) for selectively presetting the torsion bar (2) and the expansion of the helicoidal tapes against the wall of the outer member. To facilitate assembly a square socket is provided in one end of the torsion bar and a square section extension at the other for engagement by a tool to obtain the required torsion which is maintained while the tube (7) is inserted into the outer member B. In Figs. 8 and 9 (not shown) the helicoidal tape is expanded to obtain the preset torque by turning one end of the square-sectioned torsion bar, the reduced length of the helicoidal tape being maintained by running down a nut (18) which can either be screwed on to the opposite end of the torsion bar (Fig. 8) or screwed into an internal thread on the outer member B (Fig. 9).

Abstract: 1,009,349. Automatic exchange systems. STANDARD TELEPHONES & CABLES Ltd. Sept. 16, 1964, No. 37812/64. Heading H4K. A system comprising a number of switching centres includes a network of duplicate signalling channels independent of the message channels with associated processing equipment at each centre for the establishment and supervision of message connections. Thus, a call between centres X, Z employs two signalling channels, e.g. 4-wire, passing over different routes A, B with repeater stations Y. Equalization networks N are provided for the shorter route to allow for different propagation times. Conventional data transmission technique is followed, and the signals of each channel are checked for errors before transmission and on reception. If desired, a parity bit may be included in the transmission. The signals received at Z over the two routes are compared, and if they agree are passed on to the local switching equipment, or, in the case of a transit centre to the next centre. An acknowledgment signal, may be reverted when the signals are accepted, or, alternatively, a repeat signal may be reverted if they are rejected.

Title: Process for working up crude formamide
Inventor: SMEYKAL KARL
IPC: C07C233/01
Filed: 1956-12-11
Abstract: Crude formamide, as is obtained by reacting carbon monoxide with ammonia under pressure in the presence of methanol and an alkali alcoholate, is purified by continuously passing the crude product at atmospheric pressure and 130 DEG  to 160 DEG  C. through a distillation column in which it remains for short periods just sufficient to ensure that all constituents lower-boiling than the formamide are substantially separated, and subjecting the residue discharged from the column to a simple continuous vacuum distillation, the formamide being recovered as distillate.  Crude formamide is pumped through preheater 3, wherein it is heated to 100 DEG  C., to the upper part of packed distillation column 4 having top and bottoms temperatures of 100 DEG  and 145 DEG  C.  Vapours of ammonia, methyl formate and methanol are removed as overheads and condensed in condenser 5 to be used for further synthesis.  The bottoms fraction withdrawn <PICT:0834278/III/1> through cooler 8 to vessel 9 comprises formamide, not more than 1% methanol, only traces of water, and all the alkali metal compounds.  This product is transferred to vacuum distillation retort 10 which is externally heated to 120 DEG  to 130 DEG  C., and is operated under a vacuum of 10 mm. Hg. at such a rate that evaporation is immediate and no liquid collects therein.  The formamide condensed in condenser 11 and passed to receiver 13 has a purity of 99.8% and a specific gravity of 1.131. A second vacuum retort can be arranged in parallel for use while the alkali metal salts are washed from the first retort with water.
