Title: Improvements relating to crimping
Inventor: SMITH KELVIN GORDON
IPC: B30B15/22
Filed: 1961-06-08
Abstract: 944,624. Jointing by stamping. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. May 25, 1962 [June 8, 1961], No. 20765/61. Heading B3Q. A power-operated crimping machine comprises an hydraulically-operable ram and a shaped die or anvil and pump means for applying hydraulic pressure to the ram in a closed condition of a solenoid-operated hydraulic valve which can be. opened at the end of a crimping operation to release said hydraulic pressure. The machine comprises a constant stroke oil pump 1, e.g. a swash-plate type, driven continuously by a 3-phase electric motor 2, which includes a rotary valve 5 actuated from the open to the closed position by an energized solenoid 6 by rotation of a valve spindle 7 through a linkage 8. The valve 5 is connected by a pipe line 9 to a ram 10 which co-operates with die 12 shaped to effect a crimping operation on a cable terminal assembly. The pipe line 9 includes a pressureresponsive change-over switch 13, the moving contact of which is displaced in an anti-clockwise direction. A relay unit 10 comprises an energizing winding 16 with a pair of normally open contacts 17 and 18. A single-phase current is supplied to the relay 10<SP>1</SP> and solenoid 6. In operation, an assembly is positioned on the die 12 and a foot switch operated to close the contacts 15 and energize a circuit for the relay 10<SP>1</SP> which causes the solenoid 6 to be energized over closed contacts 17 to effect closure of the valve 5. The energizing circuit of the relay 10<SP>1</SP> includes a load resistor 19 in addition to the moving contact 14 and a non- adjustable fixed contact of the switch 13, and in operation completes its own holding circuit by the closure of contacts 18, therefore keeping the valve 5 closed upon the interruption of the initial energizing path of the relay as the pressure builds up and the moving contact 14 disengages the non-adjustable fixed contact. At the pre-set pressure, e.g. 10,000 p.s.i., the moving contact 14 engages the adjustable fixed contact to short-circuit the relay 10<SP>1</SP> and winding 16 causing the contacts 17 to open, interrupt the solenoid 6 circuit and bring about the opening of the valve 5 which in turn permits the die to open under the influence of a return spring (not shown). In the event of a pump failure the solenoid is de-energized by a switching means (not shown). A manually-operated switch 20 opens the motor circuit and a normally closed magnetic safety switch 21 fitted to a safety guard is connected in series with the switch 20 so that the motor will not operate unless the guard is effective. A spring-loaded safety valve may be fitted to the hydraulic system and abutments on the ram 10 and die 12 co-operate to prevent excessive loading of the cable assembly during crimping.

Abstract: Nuclear halogenated alkenylbenzenes are made by passing a vapour mixture of steam and an alkylhalobenzene having 2 or 3 carbon atoms in an alkyl radicle thereof, over a dehydrogenation catalyst at 500-750 DEG  C. to form a vapour mixture of an ar-halo-alkenylbenzene compound, steam and a minor amount of a hydrogen halide, injecting into the vapour mixture flowing from the catalyst a vaporizable basic nitrogen compound of basicity at least as great as that of ammonia in amount at least as great as the chemical equivalent of the hydrogen halide present in the reaction vapours, and cooling the resultant vapour mixture, while in contact with surfaces of a ferrous metal, to condense the ar-halo-alkenyl-benzene.  The nitrogen compound is preferably added as a vapour and those specified are ammonia and dimethyl-, ethyl- or diethyl-amine, preferred being gaseous ammonia and ammonium hydroxide.  Usually 1-3 mols. of nitrogen compound per mol, of hydrogen halide are used.  Specified alkyl halobenzenes are ethyl-chloro-, diethyl-chloro-, isopropylchloro-, isopropyldichloro-, di-isopropylchloro-, ethylbromo- and propylbromo-benzene.  Usually 1-4 parts of steam per part of substituted benzene is used. Activated alumina, particularly when precarbonized with a hydrocarbon vapour at 600-700 DEG  C., is the preferred catalyst, others specified being activated charcoal, kaolin, ordinary aluminium oxide and thorium oxide.  Reaction is preferably effected at 550-700 DEG C.  The alkenyl-halobenzene is preferably isolated by fractional distillation under vacuum in the presence of a polymerization inhibitor.  Bromo-, alpha - methyl - chloro -, alpha - methyl - 3,4-dichloro- and dichloro-styrene are obtainable from ethyl-bromo-, isopropyl-chloro-, 1-isopropyl - 3,4 - dichloro and ethyl - dichlorobenzene respectively.  In examples (2) and (3) chlorostyrene is prepared from ethyl-chlorobenzene gaseous ammonia being the added nitrogen compound and activated alumina, the catalyst and results obtained are compared with (1) in which no nitrogen compound is added.

Abstract: 887,989. Vehicles with load platforms which lower for loading. NICOLAS, J. B. June 19, 1959 [June 27, 1958; Nov. 13, 1958], No. 21203/59. Class 78 (4). [Also in Group XXXII] Wheels 2, located on either side of the chassis of a transport vehicle are mounted on arms 4 which are each pivoted about an axis 6 which is inclined with respect to a vertical longitudinal plane, and to a lesser degree, a vertical transverse plane of a platform 1b, so that on reversing the vehicle the wheels will move outwardly to raise slightly and then to lower the platform towards the ground. The inclination of each axis is such that in swinging the wheel 2 from a position OX to OY the platform 1b is raised, and on swinging it from OY to OZ the platform is lowered a small amount so that a component of the weight continuously urges the wheel 2 to a position OA. On moving the wheels 2 from position A to position B, the component of the weight acting on the wheels is overcome initially by a jack 21, Fig. 1, which can be operated from the vehicle hydraulic braking system when the platform is to be lowered. The pivoting of the arms can be limited by an abutment 44, Fig. 3, or by links 26, Fig. 1, pivoted to the arms 4 at one end, and at the other end to a nut 28, 29 which engages a screw-thread 30a, 30b on a rotatable shaft, thus co-ordinating the outward movement of the two wheels 2, 3. To prevent the loaded platform having a braking effect by resting on the ground, the platform can be provided with a hinged flap 46b, Fig. 4, of which the ground engaging underside is curved so that a tilting action is effected when the vehicle is moved forward or the tilting can be effected by means of a wheel. Each arm 4 may support a pair of wheels arranged side-by-side or behind one another. The arms 4 may be locked in the position A by a spring dowel 48, Fig. 5 (not shown). Specification 887,990 is referred to.
