Title: Torsion bar suspension system
IPC: B01D46/00
Filed: 1954-06-08
Abstract: 788.604. Spring suspensions; springs. MANNESMANN AKT.-GES. June 8, 1954 [June 18, 1953; Sept. 7, 1953], No. 16809/54. Classes 108(2) and 108(3) [Also in Group XXXIII] A torsion bar suspension system comprises means for swinging the torsion bar about an axis substantially parallel to itself and two torque-applying levers of unequal lengths rigidly attached to the torsion bar and pivoted at their ends for movement in substantially parallel planes, the difference in lengths of the levers being such that when the torsion bar is swung it is twisted through an angle which is smaller than that through which it is swung. As shown, a torsion bar 11 is rotatably mounted in parallel levers 12, 13 pivoted about axes 14, 15. Lever arms 16, 17 of different lengths rigidly connected to the torsion bar 11 are pivotally connected at their free ends in bearings 20, 21. The pivot axes 14, 15 may be carried by the bearings 20, 21 and extensions at the ends of the bar 11 may be provided to carry vehicle wheels. Alternatively, a wheel may be mounted on the bar 11 between the levers 12, 13. In another arrangement Fig. 2 (not shown) the torsion bar is rigidly supported in one lever 12 or 13 and is rigidly connected at one end to a single lever arm. According to Fig. 3 (not shown) the torsion bar is supported at each end by a lever arm and at its mid point by a shorter arm the free end of which is displaceably supported in a bearing member. This arrangement is applied to a vehicle suspension, Fig. 4 (not shown), a road wheel being carried at each end of the torsion bar. In another arrangement Fig. 5 (not shown) the ends of a pair of concentrically arranged torsion tubes are connected to lever arms, one end of one tube being connected to an arm pivoted in a bearing and the other end of the same tube being connected to a shorter arm slidingly engaging another bearing. In another arrangement, Fig. 6 (not shown) the tubes are rigidly connected together intermediate their ends, the ends of the outer tube being connected to the shorter arms and the ends of the inner tube being connected to the longer arms. In a further arrangement Fig. 7 (not shown) the inner tube is connected intermediate its ends to the shorter arm, and a pair of outer tubes rigidly connected at their outer ends to the inner tube, are connected at their inner ends adjacent the shorter arm, to the longer arms. In the arrangement according to Fig. 8 (not shown) a pair of concentrically arranged tubes is rigidly connected together at one end, the free ends of the tubes being connected to one longer arm and one shorter arm respectively. In the arrangement according to Fig. 9 (not shown) the tubes are replaced by a pair of bars arranged side-by-side and rigidly connected together at one end. The invention is applicable to spring units for seats and harbour installations.

Abstract: 716,793. Controlling change-speed gearing. CONAN. Y. Julv 17, 1951 [July 28, 1950]. No. 16885/51. Class 80 (2) [Also in Group XXVI] The impeller 3, Fig. 1, of a centrifugal compressor is driven through a change-speed gearbox comprising two epicyclic trains A, B connected in series and followed by a fixed-ratio step-up gearing C. Train A comprises planet gears 20 carried by the input shaft 15, an annular gear 23 carried by a shaft 9, and a sun gear 22 loosely mounted on the shaft 15. Train B comprises double planet gears 40, 40<SP>1</SP> carried by the shaft 9, and a gear 43 and an annular gear 50, both loosely mounted on the shaft 9 and meshing with gears 40<SP>1</SP>, 40 respectively. The sun gears 22 and 43 carry steel armatures 26 and 47 respectively, which rotate between stationary electromagnets 27, 48 and electromagnets 28, 49 carried by the shaft 9. Gearing C comprises three double gears 53, 53<SP>1</SP> journalled on stationary stub shafts 54 and meshing with a gear ring 52 carried by the sun gear 50 and with a pinion 55 carried by the impeller shaft 4. A centrifugal governor driven through gear 56 from the gearing. C comprises a disc 60 carrying balls 62 which are urged outwardly by centrifugal force and act on a disc 63 to tend to move it axially. Disc 63 bears, through a ball bearing 64, on a lever 66 carried by a shaft 67. The shaft also carries a lever 69, Fig. 3, which bears against a lever 70 in opposition to the thrust of a spring 72, which is adjustable by means of a screw 73. Variations of the impeller speed above or below its normal value cause the balls 62 to move radially. The resultant displacement of the lever 70 brings a contact 75 against one or other of two contacts 77, 78 whereby an electric motor is energized to run in one or the other direction. The motor actuates a switch for successively energizing the electromagnets whereby the appropriate one of four different speed ratios is selected. Limit switches cut off the current to the motor when it reaches an extreme position in either direction. There may be a manual control which overrides the automatic control.

Title: Improvements in or relating to the production of vinyl chloride
IPC: C07C17/08
Filed: 1960-05-13
Abstract: A catalyst for the preparation of vinyl chloride from gaseous acetylene and hydrogen chloride comprises active carbon and mercuric chloride.  It may be contained in flat tubes which can be cooled and which have a cross-section of 18 X 50 mm.ALSO:Vinyl chloride is prepared by reacting at an elevated temperature an equimolecular gaseous mixture of acetylene and hydrogen chloride in stages using a catalyst containing mercury, and separating at least a part of the resulting vinyl chloride after each stage.  In a preferred embodiment, the conversion is carried out to approximately 90% completion in a first reactor, the main part of the vinyl chloride is separated as liquid by cooling below -20 DEG C., the residual gases are again approximately 90% converted in a second reactor at a temperature from 60 DEG C.-150 DEG C., the emergent gases are cooled so strongly, e.g. to -60 DEG C., that practically all the vinyl chloride is condensed, and the uncondensed gases leave the reaction system.  More than two stages, e.g. four, may be used.  Dissolved acetylene and hydrogen chloride may be removed from the vinyl chloride in a fractionating column and the product distilled, e.g. at 4 atmospheres pressure. The catalyst, e.g. mercuric chloride/active carbon, may be arranged in flat tubes which can be cooled and which have a rectangular cross-section of 18 X 50 mm.

IPC: C07F9/564
Filed: 1952-07-07
Abstract: The invention comprises phosphoramides having the formula <FORM:0715861/IV (b)/1> in which R is hydrogen or an alkyl radical and R1 is a dialkylamino radical having 8 to 24 carbon atoms, an alkoxy radical having 4 to 12 carbon atoms, a nitrogen-containing heterocyclic radical having present at least 4 carbon atoms and having an attachment from the nitrogen atom to the phosphorus atom or an ethylenimine radical.  Such compounds are obtained by reacting a dihalophosphoric compound having the formula O = PR1X2 in which X is chlorine or bromine wth at least two molecular equivalents of an ethylenimine compound having the formula <FORM:0715861/IV (b)/2> in the presence of a hydrohalide acceptor.  The radical R1, for example, may be derived from amines: di - n - butylamine diisobutylamine, diamylamine, diheptylamine, didodecylamine or butylhexylamine; alcohols: n-, iso- or sec.-butyl alcohol, isoamyl alcohol, octyl alcohol or dodecyl alcohol; heterocyclic compounds: piperidine, 4 - methylpiperidine, pyrrolidine, morpholine, thiamorpholine, 1 - methylpiperazine, 1,2,3,4 - tetrahydroquinoline or 1,2,3,4 - tetrahydro - isoquinoline; ethylenimines: 2-methyl-, ethyl-, propyl-, or hexyl-ethylenimine or 2,2-diethylethylenimine.  The ethylenimines mentioned may also be used in the reaction with the dihalophosphoric compound.  In examples: (1) N,N-diisobutylamidodichloro-phosphoric acid and ethylenimine are reacted to give N,N-diisobutyl-N1,N11-diethylenephosphoric triamide; (2) N,N-dioctylamidodichlorophosphoric acid (prepared from di-n-octyllamine and phosphorus oxychloride) is reacted with ethylenimine to give N,N-di-octyl - N,N11 - diethylene-phosphoric triamide; (3) n-octyl dichlorophosphate (prepared from n-octyl alcohol and phosphorus oxychloride) is reacted with ethylenimine to give octyl N,N1-diethylenediamidophosphate.  Similarly prepared are (4) butyl N,N1-diethylenediamido phosphate; (5) N-pentamethylene-N1,N11-di-ethylenephosphoric triamide; (6) N-(3-oxapentamethylene) - N1,N11 - diethylene phosphoric acid triamide (using N-(3-oxapentamethylene)amidodichlorophosphoric acid prepared by reacting morpholine hydrochloride and phosphorus oxychloride); (7) N-pentamethylene - N1,N11 - bis - (1 - methylethylene)-phosphoric triamide; (8) N-pentamethylene-N1,N11 - bis - (1,1 - dimethylethylene) - phosphoric triamide. N,N1,N11-tris-(1-methylethylene) phosphoric triamide and N,N1,N11-tris-(1,1-dimethylethylene) phosphoric triamide are prepared by reacting phosphorus oxychloride with 2-methylethylenimine and 2,2-dimethylethylenimine respectively in examples (9) and (10).  The products may be used therapeutically, or as textile chemicals or may be polymerized to yield plastics.

Title: Improvements in or relating to metal vapour electric arc converters
Inventor: BOOTH ARTHUR JERRARD
IPC: H01J13/10
Filed: 1956-06-01
Abstract: 820,085. Metal-vapour converters. GENERAL ELECTRIC CO. Ltd. May 31, 1957 [June 1, 1956], No. 17021/56. Class 39(1). In a cathode arrangement in or for a metal vapour electric arc converter, vaporisable metal for producing an arc discharge is arranged to be fed to the surface of a cathode spot anchoring member from a reservoir separated from the main discharge space in the converter and returned to the reservoir, the arrangement being such that in operation, an arc discharge is maintained by the vaporisable metal in contact with the said surface without the metal forming a main cathode pool in the discharge space of the converter which might be switched by movement of the converter. The single anode mercury arc rectifier shown comprises a cnylindrical evelope 1, an anode (not shown), an igniter 2 for striking an arc, a cathode spot anchoring member 3 and a reservoir 4 for the cathode mercury. The envelope, anode and igniter may be as described in Specification 817,504. The cathode spot anchoring member 3 is an inverted cupshaped member of molybdenum and is preferably cooled by fluid impinging directly on its inner surface as described in Specification 810,387. The reservoir 4 is connected with the discharge space 5 by one or more passages 6 which are lead through perforations 7 in the wall of the cathode spot anchoring member 3. Mercury is pumped to the outer surface of the member 3 by a circulating pump 10 and returns to the reservoirs 4 by way of return passages 8. The cathode spot or spots are anchored to the member 3 at the recess adjacent to the perforations 7. In an alternative arrangement the member 3 is dome shaped and a single passage is lead from the reservoir to the uppermost part of the domed surface. Mercury fed to the surface runs down to a narrow arcuate trough, formed on the cathode member, which retains a small quantity of mercury for producing an auxiliary discharge with an exciting electrode. In a further embodiment the reservoir is provided with means such as a resistance or a heat exchanger deriving heat from a cooling system for the anode or other part of the rectifier for heating the mercury and mercury vapour is directed by a heat pump onto one or more localities on the outer surface of the member 3 where it condenses and is returned to the reservoir.

Title: Improvements in or relating to internal combustion engines
IPC: F02M57/02
Filed: 1931-06-12
Abstract: 373,443. Oil engines. RUTZEBECK, A. V., 310, S÷dert÷rnsvõgen, Enskede, near Stockholm. June 12, 1931, No. 17128. [Class 7 (iii).] In a multi-cylinder engine liquid fuel and air are supplied to an injector 13, Fig. 4, the fuel being delivered by a diaphragm pump, Fig. 2, which is actuated by the compression or explosion pressure in a cylinder other than that into which the fuel is being injected, the injection air blast being also transmitted from the pump-actuating cylinder. In the engine shown in Fig. 1 the main air supply is admitted by a branched pipe 10 through valves 9 and fuel is supplied by a branched pipe 12 to pumps 15I-IV these having fuel and air delivery pipes 14I-IV and 17I-IV respectively connected to the injectors 13I-IV of the cylinders which they supply. The firing sequence is I, II, IV, III, and the injectors and pumps are so connected that during portions of the compression and/or firing strokes of, for instance, cylinder I fuel is injected by pump 151 to the injector 13II of cylinder II during the suction and/or compression strokes of the latter; fuel is drawn into the pump 15II during the suction stroke of cylinder II in readiness for supplying injector 13IV when the charge in cylinder II is fired by an igniter 16. Atmospheric air is also drawn into the branch 18I-IV of each pump, during the suction strokes of the associated cylinders, through a non-return valve 37, Fig. 7, and is discharged during the compression stroke by a free piston 42 through a non-return valve 39 to the associated injector through pipes 17I-IV; the piston 42 and buffer spring 43 may be omitted, in which case some of the products of combustion may mix with the injection air. The injection nozzle, Fig. 4, has radially converging discharge orifices 32 and a lateral orifice 33 which directs a stream of fuel towards the igniter 16. A ball valve 31 closes the feed passage 28 of the injector when the cylinder pressure exceeds the injection pressure. The injectors may be located in the air pipes 10 instead of in the cylinder heads. The diaphragm 19 of the fuel pump, Fig. 2, contacts with a member 23 which serves to absorb the oscillations of the diaphragm. The quantity of fuel supplied by the pump may be adjusted by a screwed stop 24 which limits the delivery stroke of the member 23.
