Abstract: 904,025. Forging; extruding. TEXTRON INDUSTRIES Inc. Nov. 12, 1958 [Dec. 18, 1957], No. 36449/58. Class 83 (4). In a heading or like machine having a die bed 11, Fig. 2, with a plurality of dies 45, 46 cooperating with reciprocating punches 15, 62 and a transfer mechanism with gripping fingers 90, 91, Fig. 4, for moving the workpiece between the dies, the transfer mechanism is mounted for movement from an operative position, Fig. 4, into an inoperative position, Fig. 10 (not shown), above the die bed and when in the latter position its driving means is still operative. Wire stock 48, Fig. 1, is fed through a cut-off die 47, Fig. 4, against a stop 49 and severed by cooperating cutters 50, 51 which transfer the workpiece opposite an extruding die 46. The cutters are actuated through linkage such as 53, 54, 57 by cams on a side shaft 42 driven through bevel gearing from a half-speed shaft 74 coupled by reduction gears 75, 76 to the main crankshaft 21. The workpiece is pushed into die 46, Fig. 2, wherein its shank is partly extruded, Fig. 9 (not shown), by a punch 62 driven positively in both directions through adjustable linkage 64, 66, 68, 70, 85 by cams 73, 87 on the shaft 74; a breaker plate 83 and adjustment screws 81, 78, 84 are included. An ejector 163 actuated positively in both directions through adjustable linkage 164, 166, 167, Fig. 5, from a cam 172 on shaft 145, removes the workpiece from die 46. This ejection is assisted by the gripping fingers 90, 91, which have engaged the workpieces and are first moved axially away from the die face, Fig. 9 (not shown), by means of linkage 135, 138, 140, 142 driven from a cam 144 on shaft 145; a spring-biased plunger 148 is included with this linkage. Gripping fingers 90, 91 then transfer the workpiece opposite heading die 45, Fig. 4, the transfer movement being produced by adjustable linkage 94, 103, 101, 107, 116, 112 driven by cams 118, 115, on shaft 42; the followers are biased against their cams by spring plungers 120. Adjustable stops 109, 110, 126 and a spring-loaded lostmotion coupling 133 are provided. The transfer mechanism may be tilted upwardly about the axis of pin 155, Fig. 5, into an operative position where the gripping jaws can be adjusted against a template 185, Fig. 10 (not shown). The mechanism is clamped by screws 160 in its operative position. The fingers move inwardly to insert the workpiece into die 45, in which it is headed in two stages by punches 15, 16, Fig. 1, mounted on a transversely slidable head 24 of the main gate 14 which is actuated through connecting rods 18, 19 from the crankshaft 21. The head 24 is moved transversely through adjustable linkage 33, 35 by a pair of cams 40, 41 on shaft 42; relatively slidable members 29, 30, Fig. 2, allow for reciprocation of the gate. From die 45 the headed workpiece is finally ejected by a rod 175 actuated through linkage 176, Fig. 1, 178, 181 by cam 182 on shaft 74. Specifications 904,026 and 904,027 are referred to.

Title: Improvements relating to the production of alkylated boranes
Inventor: LONG LEONARD HAYNES
IPC: C07F5/02
Filed: 1960-10-24
Abstract: Alkylated boranes (particularly diboranes and polyboranes) are made by reacting an aluminium trialkyl Al(Alk)3 or an aluminium alkyl halide Al(Alk)mX3-m where m=1 or 2, or a mixture of the two, with a metal borohydride and with a hydrogen halide or boron trihalide.  For example, there may be used sodium or lithium borohydride with hydrogen chloride or boron trichloride. The aluminium alkyl halide may be formed in situ from the corresponding aluminium trialkyl and aluminium trihalide. Temperatures are within the range of 0-250 DEG C., 60-180 DEG C. being preferred.  When the alkyl groups are methyl or ethyl, pressures 20-120 atm. are suitable.  Atmospheric pressure may also be used when the alkyl is ethyl and is preferred when it is propyl or butyl.  The main products are alkylated diboranes but alkyl derivatives of higher boranes, such as alkylated pentaboranes are also formed, particularly when using temperatures of 150-200 DEG C. Detailed examples are given. Specification 853,063 is referred to.

Title: Novel hydrazine derivatives and salts and a process for the manufacture thereof
Filed: 1962-09-26
Abstract: The invention comprises hydrazines of the general formula A-NHNH-CH3, the azo and azoxy compounds corresponding thereto, and their acid addition salts, where A represents a saturated or unsaturated aliphatic hydrocarbon radical which, when a saturated chain optionally contains one or more halogen atoms, cyano, carboxyalkyl (optionally esterified), hydroxylalkyl (optionally esterified or etherified), alkylthio, aminoalkyl, hydrazinoalkylamino-alkyl in which the remaining hydrogen atom in the amino group may be replaced by a benzyloxy-carbonyl radical, aminoalkoxy, acylamino, ureido, thioureido, guanidino, amidino, carbamoyl, allophanoyl, alkylsulphonyl, acyl, methylhydrazinomethyl,methylhydrazinoalkoxy, or methylhydrazinoalkylcarbonyl group and the preparation thereof by either reacting methyl hydrazine or a methyl hydrazine in which the hydrazine is partially substituted by protecting groups with a compound which yields the radical A1 (wherein A1 has the same meaning as A or is a group which is convertible into A) or methylating a hydrazine which contains such a radical as a substituent or a hydrazine which not only contains such a substituent but is also partially further substituted by protecting groups, and, in either case if necessary, converting the radical in the product into A and, also if necessary, converting the resulting compound into an acid addition salt, said compound or its salt if necessary then being oxidized to the corresponding azo or azoxy compound.  In a variation of the above process methyl hydrazine or a methyl hydrazine in which the hydrazine is partially substituted by protecting groups is reacted with an appropriate carbonyl compound and the hydrazone is subsequently reduced and the protecting group split off.  Cis and trans 1,2-bis-(iodomethyl)-cyclopropane are prepared by reducing cyclo-propane 1,2-dicarboxylic acid diethyl ester to give 1,2-bis-(p-hydroxymethyl) cyclo propane, forming 1,2 - bis - (p - tosyloxymethyl) - cyclo propane as cis and trans-isomers and reacting these with sodium iodide.  Pharmaceutical compositions comprise the compounds of the invention together with a compatible pharmaceutical carrier and are formulated as tablets, dragees, suppositories, capsules, suspensions and emulsions.  The compositions may contain other therapeutically active ingredients.  The compounds of the invention are cytostatic agents.

Title: Improvements in and relating to current collecting devices for dynamo electric machines or the like
IPC: H01R39/04
Filed: 1920-12-31
Abstract: 177,609. British Thomson - Houston Co., Ltd., (General Electric Co.). Dec. 31, 1920. Commutators and collecting - rings. - In a dynamo commutator or other apparatus in which current is led to or from a rotating body, the ring-shaped collecting-member 11 is clamped under pressure in a holder between clamping- means and resilient insulating material, composed of layers of textile fibrous material, with or without intervening layers of non-resilient insulating material, whereby thermal expansion and contraction of the commutator or the like are taken up. The fibrous material may be cotton batting, soaked in water for softening and compressed into sheets with a pressure of the order of 12,000 lb. per sq. in. A substance such as starch may be added to the water to form a temporary binder, and the pressed sheets are cut into rings which are oven-dried before assembly. In the form shown in Fig. 1, the shallow segments 5 are mounted in the holder 8, which has an inturned flange at 10, on insulating-rings 9 and a tube 7 made of paper soaked in shellac, the material known under the registered Trade Mark " Bakelite " or the like. Fibrous rings 12, as previously described, are placed at each end and the retaining-member 11 is then secured under pressure by expanding the end of the holder 8. The material 12 mav be coated with layers of elastic varnish between successive bakings. In an alternative form, Fig. 2, specially suitable for high voltages, the segments 5 are held between layers of compressed textile fibrous resilient and non-resilient insulating material 16, 14 of such axial length as to give a long surface leakage path. The dovetails may be channelled at 5<a> to give a firm anchorage to the material 16. The initial compression of the resilient material is such that expansion of the commutator will not stress the fibres sufficiently to destroy their resiliency.

Abstract: 324,183. Hall, F. H. Dec. 12, 1928. Compensating for wear; hand, foot, and personal actuation.-In a self-adjusting brake mechanism a ratchet device operated by the pedal controls the movement of a slack adjuster in the brake rod, the adjusting device being operated after the ratchet device has been retained in an advanced position and on the return stroke of the pedal. The brake pedal 4 is pivoted at 31 and is connected to the brake by a rod 8, slack adjusting device 15. 16 and rod 14. The slack adjuster comprises a double pulley block 15, 16 around which passes a wire rope 17, one end being connected to the block 16 and the other to a drum 19 carrying a ratchet wheel and loosely mounted on the pivot 31. Two pawls engage the ratchet wheel, one of which 22 is mounted on the brake pedal and the other 24 on a, fixed part of the chassis. When slackness has developed in the brake gear and the brake pedal is depressed the ratchet wheel on the drum 19 turns and the pawl 24 slips over a tooth. On release of the brake pedal the drum is held by the pawl 24 and the pawl 22 slips over a tooth when the pedal reaches its normal position and the slack is taken up. As applied to the lever described in Specification 301,943 the ratchet wheel 21 and drum 19, Fig. 1, is mounted on a pivot 3 and the cable 17 is passed through a pin 10 securing the rod 8 to the block 15. The pawl 22 is mounted on the brake pedal 4 and the pawl 24 on the link 1 which is pivoted at 2 to the chassis or engine case. The pedal 4 and link 1 are drawn together against stops by a spring 6 and a stop 7 for the link 1 is mounted on the chassis. The pulley blocks 15, 16 are enclosed in a fabric casing 26 supported on a spring 27 retained between end plates 28, 29. On application of the brake the brake pedal 4 and link 1 move together to take up the brake clearance and slack until a sufficient resistance is offered by the brake, or the link 1 engages the stop 7, thereafter the pedal 4 moves relatively to the link 1 about the pivot 3 to apply the brake at an increased leverage. When excessive slackness is present, the movement of the pedal 4 about the pivot 3 rotates the ratchet 21 so that the pawl 24 engages a fresh tooth. On release of the brakes the pawl 22 slips back one tooth and the slack is taken up. According to the first Provisional Specification the pawls 22, 24 may operate ratchet wheels.
