Title: Improvements in or relating to motor car headlamps and the like
IPC: B60Q1/14
Filed: 1934-11-13
Abstract: 433,112. Vehicle lamps. HUNT, W. T., Boddington, Western Avenue, Acton, London. Nov. 13, 1934, No. 32677. [Classes 75 (ii) and 75 (iv)] In a vehicle lamp in which the reflector is mounted for universal movement and is connected by suitably guided cables or the like with a lever mounted for universal movement adjacent the driver's seat so that in whatever direction said lever is moved a corresponding movement of the reflector will result and the beam of light will be deflected in any desired direction, the lever, or a part thereof, is arranged for axial movement relatively to the universal mounting and is connected with a lamp holder which is slidable relatively to the reflector for focusing purposes. In the form shown in Fig. 3, the reflector 17 is trunnion mounted by means of a ring 15 pivoted in a ring 13 which is pivoted at 14 in a ring 12 fixed to the lamp casing 11. On the axis of the pivots 14, the ring 15 carries a boss 27 to which is attached the inner element 26 of an operating cable, the outer element 25 of which is secured to an angular arm 24 carried by the ring 13, a coiled spring 28 surrounding the element 26 being disposed between the boss 27 and the end of the arm 24. A second cable is similarly connected to the ring 13 on the axis of the pivots of the ring 15. The holder 51 for the bulb 57 is slidably mounted in a tubular extension 52 of the reflector 17, the holder having lateral lugs 53 which project through slots in the tubular extension and engage under a channel section ring 54. A similar ring 55 bears against a bridge 50 secured to the back of the reflector, and a coiled spring 56 is arranged between the two rings 54, 55. The inner element 46 of a third cable is connected to the holder 51 and its outer element 49 is connected to the bridge 50. The actuating lever 29, Fig. 4, is screwed into a ball 30 which seats in a cup 31 carried by a barrel 32 containing a U-shaped abutment 39 and two angular abutments 40, 41. The ball 30 is formed with four equiangularly spaced recesses 33 connected to grooves 34, and in two of these recesses at right angles to one another are disposed solder heads on the ends of the inner elements of the first and second cables, their outer elements being adjustably attached to the abutments 39, 41. Each of the other recesses contains a similar head on a wire 35 attached to a plate 37, between which and a plate 44 is arranged a coil spring 45 to balance the pull of the corresponding cable, the plates 44 being attached by wires 42 to the abutments 39, 40. The inner element 46 of the third cable passes through a flared opening in the ball 30, an axial bore in the lever 29, and the end of a sleeve 47, against which latter seats a head 48 on the end of the element 46. Rotation of the sleeve 47 relatively to the lever 29 therefore causes movement of the bulb 57 with respect to the reflector 17. The first and second cables may be replaced by four cables producing closed circuits without springs.

Patent GB-618402-A (GB)
Title: Improvements in and relating to swaging machines and feeders therefor
IPC: B21F23/00
Filed: 1946-11-04
Abstract: 618,402. Forging. BRITISH THOMSON-HOUSTON CO., Ltd. Nov. 4, 1946, No. 32721. Convention date, Nov. 3, 1945. [Class 83 (iv)] A swaging-machine comprises a swaging-head and means for automatically inserting a length of wire therein, comprising a wire storage hopper adjacent to the head, a vertically reciprocating elevator for selecting the wires in the hopper and placing each in position opposite the aperture in the head, horizontally reciprocating work inserting means to engage and grip each positioned wire and advance it endwise into the aperture, and means for actuating the elevator and work-inserting means in timed relationship. The invention is described as applied to the manufacture of leading-in wires for large electric lamps, wherein one end of a piece of wire is first formed with a hook for the filament and the other end is tapered down to the size of the seal wire portion. The wires 4, with hooked ends 7 are lifted out one at a time from a hopper 5 by a slide 9 into position opposite and in alignment with the aperture 3 in a swaging-head 1. The stroke of the slide 9 is adjusted by the engagement of a stop screw 18 with a lug 19 and the slide is operated through levers 20, 21 and 27 and connecting-rod 25 from a cam 34 mounted on a shaft 35 driven by an electric motor 36 through a gear train 37 to 40. Springs 44, 45 tend to maintain the slide in its elevated position. The work-piece 4 is advanced into the swaging-head 1 by a reciprocating push-rod 49 carrying a head assembly 50, Fig. 4, which engages and grips the hooked end portion 7 of the wire 4 between jaws 55 which are closed on to the wire by a spring 61 during the advance of the push-rod 49 which moves rolls 60 along divergent cam surfaces 63 of a cam plate 64 carried by a bracket 65, the slide 9 then retracting due to the rise on the cam 34. The movement of the push-rod 49 is imparted by a lever 66 held against a cam 70 on the shaft 35 by a weight 71 suspended by a steel tape 72 passing over pulleys 73, 74 and connected to the lever 66. The weight is used in preference to a spring to ensure that the wire 4 does not vibrate during its insertion into the swaging head. The forward movement of the rod 49 is adjusted by a stop screw 78 engaging the lever 66, a scale 82 indicating the amount of forward movement. After swaging is completed, the rod 49 is retracted by the rise on the cam 70 and the slide 9 begins its next upward stroke. During the last stage of the retracting movement of the rod 49, the rollers 60 ride on the converging surfaces 63 and cause the jaws 55 to open, thereby releasing the wire 4 which falls on a movable deflector plate 83 which guides it into a stationary shoot 84. The deflector plate 83, fastened to a swinging arm 86, is constrained to its wire-deflecting position by a plate spring 89 and is swung out of the way of the upward movement of the slide 9 by the engagement of the end of the slide with the inclined portion 90 of the deflector plate 83.

Title: Improvements in or relating to indole derivatives
Inventor: WRAGG WILLIAM ROBERT
IPC: C07D209/12
Filed: 1955-11-18
Abstract: The invention comprises indole-aldehydes of the formula <FORM:0839628/IV (b)/1> where R is aralkoxy, and their preparation from the corresponding R-substituted indoles by reaction with an N : N-disubstituted formamide in the presence of a condensing agent and alkaline hydrolysis of the product.  The aldehydes can be condensed with a nitroalkane to give 3-nitro-alkenyl-indoles, which may be then reduced at the nitro group and the double bond and hydrogenolysed to give 3-(21-aminoalkyl)-hydroxyindoles.  In examples 5-benzyloxy-indole is condensed with dimethylformamide in the presence of phosphorus oxychloride and the product hydrolysed to 5-benzyloxyindole-3-aldehyde.  Condensation of this with nitroethane gives 5-benzyloxy-3 (21-nitroprop - 11 - enyl) - indole, which is reduced with lithium aluminium hydride to 5 - benzyloxy-3 - (21 - aminopropyl) - indole (isolated as sulphate).  Hydrogenolysis then yields the sulphate of 5 - hydroxy - 3 - (21 - aminopropyl)-indole. Serotonin can be made similarly.

Title: Improvements in resolution of mixture by crystallization
IPC: B01D9/00
Filed: 1956-10-31
Abstract: <PICT:0828837/III/1> In a crystallization process wherein a partially crystallized mixture is passed through a filtration and liquid removal zone, a reflux zone and a melting zone, part of the melt being withdrawn and the remainder being refluxed in the reflux zone, the materials in these zones are subjected to a pulsating pressure in the direction of the passage of the crystals, the pressure being applied at a point upstream from the point of liquid removal and downstream from the points at which the mixture is partially crystallized and propelled towards the zones.  A feed mixture containing a component separable by crystallization is fed by a pump 11 to a chilling section A, where a crystal mass is obtained together with mother liquor, which is passed to a filter section B.  Filtrate passes through a filter screen 27 and is removed by an outlet 29.  A pulsation producing member E, comprising a cylinder 33 and a reciprocating piston 34, provides a continuous series of pressure waves travelling in the same direction as the crystal mass which advances through a reflux section C towards a melting section D.  As the crystal mass approaches the melting section D some of the crystals are melted to provide a reflux which is removed with the mother liquor in the filter section B, and molten product is removed through a line 45.  In examples 2-methyl-5-vinylpyridine is separated from mixtures also containing 2-methyl-5-ethylpyridine.  Lists of materials which may be separated from mixtures containing them are given.

Title: Oil-soluble bismuth salts and process for their production
IPC: C07F9/94
Filed: 1937-12-01
Abstract: 506,593. Bismuth carboxylates. LILLY & CO., E., SHONLE, H. A., and WALDO, J. H. Dec. 1, 1937, No. 33271. [Class 1 (iii)] Oil-soluble basic bismuth salts of acids of the formula where R represents a monovalent primary aliphatic radicle having at least 5 carbon atoms and R<1> represents an alkoxy group having not more than 4 carbon atoms, are obtained by reacting the acid or an alkali metal salt thereof with a freshly prepared bismuth compound which is soluble in a water solution of glycol, such as the hydroxide or subnitrate. The term monovalent primary aliphatic radicle is defined as a noncyclic radicle in which the attaching carbon atom is joined to only one other carbon atom of the radicle. It may be the iso-amyl, 2-ethyl-butyl, 2-methylpentyl, 2, 4-dimethyl-pentyl, 2-ethyl-hexyl, decyl, do-decyl (lauryl), octadecyl, or 9, 10- octadecenyl radicle, and the radicle R<1> is preferably the ethyl radicle, though it may be methyl, propyl, or butyl. In carrying out the invention, a solution of bismuth subnitrate in aqueous glycerine or mannitol may be reacted in the cold with the sodium salt of the acid ; or bismuth hydroxide be heated with the acid under reflux in the presence of a little water. In either case the reaction product is extracted with ether or benzene, and then recovered by distilling off the solvent. Solutions in oil of the basic bismuth salts are effective spirocheticidal agents, and may be injected intramuscularly. Bland mineral oils may be used for those compounds wherein R has at least 8 carbon atoms, or vegetable oils such as olive oil, cottonseed oil, coconut oil, or sesame oil, or ethyl oleate or the ethyl ester of the fatty acids of sesame oil may be employed.

Title: Improvements in or relating to hydraulic motors
IPC: F03C1/40
Filed: 1956-11-02
Abstract: 796,476. Engine turning-gear. GENERAL MOTORS CORPORATION. Nov. 2, 1956 [Nov. 7, 1955], No. 33461/56. Class 7(5) [Also in Group XXIX] A hydraulic engine-starter motor is of the swash-plate type and has a rotatable cylinder block 34 splined to an output shaft 26 and mounted by means of needle bearings 44, 46 in a stationary housing. The output shaft drives the input member of an overrunning clutch 135, the output member of which has a spline connection with a pinion 130. The clutch 135 and pinion 130 are shiftable to the right by a lever assembly to engage the pinion with a flywheel ring gear 132 of an engine. The lever assembly also actuates a spindle 96 of a valve 80 controlling the supply of liquid to the inlet kidney port of the motor. The lever assembly is biased by a torsion spring to maintain the clutch and gear 130 and spindle 96 in their left-hand positions in which spindle 96 blocks communication between a valve inlet chamber 92 and an outlet chamber 78 which leads to the inlet kidney. When the lever assembly is actuated, the pinion 130 is shifted into full engagement with the ring gear 132 before the valve spindle 96 is shifted to its fully opened position. Should the teeth of gears 130, 132 abut, and prevent engagement, further movement of the lever assembly is permitted by compression of a spring 136 between the clutch and pinion 130. If the splines on the clutch and pinion are helical this further movement will effect limited rotation of the pinion. The spring is compressed until abutment occurs between parts of the clutch and the pinion, in which position of the lever assembly the valve spindle is in a position in which ports 108 and a port 111 are aligned with chambers 92, 78 to give a restricted flow of liquid to the motor to produce a slow rotation. When gears 130, 132 are fully engaged valve ports 108, 110 are aligned with chambers 92, 78 to give full flow to the motor.
