Title: A process for the production of polymers of conjugated dienes
Inventor: NUETZEL KARL
IPC: C08F4/06
Filed: 1965-01-13
Abstract: Polymers of conjugated diolefins are produced by polymerizing  (A) 100 to 30% by weight of one or more conjugated diolefins and either (B) 0 to 50% by weight of a copolymerizable vinyl or vinylidene monomer with an activated double bond, or  (C) 0 to 70% by weight of styrene at temperatures from -20 DEG  to +150 DEG  C. in the presence of a catalyst which is a compound of the general formula MeSiR3 wherein Me represets a sodium or potassium atom and each R, which may be the same or different, represents a C1 to C8 alkyl radical, a phenyl radical, a C1 to C8 alkyl-substituted phenyl radical, a cycloalkyl radical having 5 to 7 carbon atoms, or a C1 to C8 alkyl-substituted cycloalkyl radical having 5 to 7 carbon atoms, at least one of the radicals R representing a phenyl or alkyl phenyl radical.  Polymerization is carried out in the presence of 10 to 500% of solvent by weight of the monomers.  When the solvent is toluene it is found that aromatic nuclei become bonded to the polymer chain. The polymerization reaction may be stopped by adding a protonactive substance, e.g. water and acetic acid. The comonomers exemplified are acrylonitrile and methyl methacrylate; in the case of acrylonitrile a small amount of the nitrile homopolymer is formed.  The polymers are generally oils or semi-solids.

Title: Improvements in operating systems for gas blast circuit breakers
IPC: H01H33/32
Filed: 1940-01-30
Abstract: 535,365. Valves. BRITISH THOMSON-HOUSTON CO., Ltd., COX, H. E., and NICHOLSON, H. E. Jan. 30, 1940, No. 1822. [Class 135] [Also in Group XXXVII] A pneumatically-operated gas-blast switch has a trip mechanism in the closing valve-operating mechanism so that if the opening valve is energized while the closing valve is open to supply gas for closing 'the switch, the closing valve is moved to the closed position, as by a spring. The closing and opening valves 2, 17 respectively, are operated by electromagnets 5, 6, the former being energized by a relay 13 of the kind which, when momentarily energized, closes and remains closed for a period. Relay 13 and electromagnet 6 are selectively energized by upper and lower contacts, respectively, of a push-button switch 27, the circuits including upper and lower contacts of an auxiliary switch 29 operated by the main switch in such a way that both movable elements occupy the positions shown when the main switch is open, and when the main switch is being closed the upper one changes over, followed by the lower one, so that both are in the left-hand position while the main switch is closed. To close the switch, valve 2 is moved to the right by electromagnet 5 through a lever 7 the pivot 8 of which is held fixed by a further lever which intermediately of its ends is pivoted at 10 and which carries at its free end a roller 11 engaging normally in the end of a further lever 12 having an intermediate pivot. Thus if electromagnet 6 is energized, lever 12 is moved thereby clear of roller 11 and 8 is no longer retained. Valve 2 comprises two valve members, one 15 of which opens to exhaust the rear side of the opening cylinder whereas 16 opens to admit the pressure from pipe 1 to the closing cylinder. The opening valve 17 similarly opens to exhaust the back of a piston 21 to atmosphere, whereby pressure from 1 moves piston 21 to admit pressure to the opening. cylinder. Valve 17 also exhausts the back of a piston 22 of the blast valve 4, thereby enabling the back of piston 25 to exhaust through orifice 26, pipe 23, and a valve 24, which is controlled by the main switch so as to be open when the latter is closed and, to close at an adjustable point in the opening stroke. Piston25 is moved to the left by the pressure from pipe 1 and admits the blast to pipe 4<SP>1</SP>. Pistons 21, 22, and 25 are spring-closed and are loose fits in their respective cylinders, so normally enabling the pressure on either side to be equalized, while permitting them to be opened against their springs when their rear faces are opened to atmosphere. Thus when valve 24 closes, pistons 22, 25 close and cut off the blast at the pre-determined point in the opening stroke.

Abstract: 1530373 Flare stack burners JOHN ZINC CO 16 Jan 1976 [24 Feb 1975] 01841/76 Heading F4T A flare stack 10 comprises means such as a blower 24 supplying combustion air to one end of a cylindrical conduit 12 having at the other end a burner 15 comprising a gas supply pipe 14 and a plurality of equally spaced radial arms 16 each having a plurality of gas ports 36A, there being between each pair of arms 16 a baffle 20 having a triangular base 20C and walls 20A, 20B extending downstream of the base parallel to the air flow and to the arms and attached to the wall of the conduit at 48, spaces 22 being defined between the baffles 20 and the adjacent arms 16 there being at least one opening 52 through the conduit wall into the interior of each baffle. Thus combustion air flowing along the conduit 12 is constrained to flow through the spaces 22, thereby being accelerated, causing turbulent mixing with gases from the ports 36A and inducing air to flow through the openings 52 and over the baffles to inhibit the accumulation of soot. Upstream of the burner are two semicircular dampers 26, 27 rotatable about a diametral rod 23 and urged by springs 29, 30 against stops 34 to close the conduit 12 when the flow of air towards the burner is not sufficient to rotate the dampers to the open position, 26<SP>1</SP>, 27<SP>1</SP>, so that flow of hot gas or flame towards the blower, caused for example by wind gusts, is prevented.

Title: Improvements in or relating to power transmission systems
IPC: F16H57/038
Filed: 1944-02-02
Abstract: 575,034. Motor-vehicle driving and steering gear. TARLTON, F. H. Feb. 2, 1944, No. 1944. [Class 79 (ii)] In a power transmission system of the kind in which a power shaft drives one driving shaft of an epicyclic or other transmission gearing through a main clutch and also drives a second driving shaft of the transmission gearing through a slipping clutch so that the velocity ratio afforded by the gearing can be varied by varying the extent to which the slipping clutch slips, each driving shaft of the gearing carries a driven element of the respective clutch and has a tubular shaft mounted on it, each tubular shaft is secured to the driving element of the respective clutch, the tubular shafts are geared together and the driving element of one clutch is connected to the power shaft. In the construction shown applied to the driving and steering gear for a tank described in Specification 573,528, the engine or power shaft 10 drives through a main clutch 13 a driving shaft 12 and this shaft drives a transverse shaft 14 through bevel gears 15 and variable gearing 16. The shaft 14 drives the two endless tracks through epicyclic gears (not shown), the reaction members of which are normally stationary, but can be driven in opposite directions by auxiliary steering mechanisms to accelerate one track and retard the other. .This auxiliary mechanism comprises a shaft 17 which can be driven from the power shaft through a slipping clutch 39 and drives the epicyclic reaction members in opposite directions through bevel reversing gearing 20. The driven members 25, 42 of the main and slipping clutches are respectively fixed to the shafts 12, 17 and the driving members 30, 43 are fixed to hollow shafts 21, 35 geared together by gear-wheels 24, 38, the clutch members 30 being in permanent driving connection through a cover-plate 28 with the power shaft 10 so that the hollow shafts 21, 35 are always in rotation. The main clutch is engaged by springs 31 and is disengaged by the usual mechanism 32. The slipping clutch 39 is engaged to any desired extent by means of a pneumatic or hydraulic device 44 so that the shaft 17 can be driven at any desired speed. This shaft, when one or other of two cone clutches 18, 19 is engaged, drives two coaxial transverse shafts in opposite directions through the bevel gears 20 and each of these oppositelyrotating transverse shafts drives the reaction member of the epicyclic gear of the corresponding track so that the vehicle is steered. The gearing is enclosed in a casing 11, but the clutches 13, 39 are outside the casing and heat is thus more readily dissipated. Since the hollow shafts 21, 35 are permanently geared together, the power shaft 10 may be connected directly to the slipping clutch 39 and the shaft 35, as indicated in broken lines, instead of to the main clutch 13 and shaft 21.

Abstract: 982,614. Spray-producers. M. VIARD. Jan. 18, 1963 [Feb. 8, 1962], No. 2231/63. Heading B2F. In a portable liquid sprayer in which depression of a spring-loaded push button 7 forces air from a chamber 10 to eject as a liquid-laden spray through an orifice 11 having entrained liquid contained in a felt disc 18, a plunger rod 20 depends from the button such that a passageway 21 formed therein provides at the inner limit of the button travel, communication between the disc and a reservoir 1. When used initially, repeated depressions of the button are necessary to pressurize the air above the liquid 2, part of the air from the chamber 10 passing through the passageway 21 on every depression. Such pressurization eventually forces liquid to pass through a pipe 15 and nozzle 14 up around the annular clearance e between rod and nozzle such that it flows through the passageway when the rod is next at its lowermost position. As the liquid level in the reservoir drops it is necessary to periodically re-pressurize the air in the reservoir by repeated depressions of the button. Instead of a passageway 21 the rod may be formed with an annular groove, a longitudinal peripheral slot or an axially disposed passageway connected with the cylindrical surfaces through radial passages. Again, the rod may be hollow with suitably spaced orifices in the wall thereof.
