Title: Improvements in bomb slips, towing gear and analogous releasable attachments
IPC: B64D1/04
Filed: 1942-10-20
Abstract: 572,809. Releasable fastenings ; hooks. VICKERS-ARMSTRONGS, Ltd., PIERSON, R. K., and FIRMAN, R. A. Oct. 20, 1942, No. 7918/43. Divided out of Complete Specification of 572,794. [Class 44] [Also in Group XXI] Relates to electromagnetically-operated release mechanism for the dropping of bombs and other articles from aircraft and for towing connections, of the kind in which the loadengaging hooks &c., are normally secured by a toggle mechanism, and consists in providing a rotary armature to impart a lateral blow to the toggle mechanism to release the load. As shown, a bomb shackle 65 is supported by hook jaws 62, 63 pivoted on a common pivot 64. The jaws have pincer-like extensions beyond the pivot provided with plane faces 621, 631, slightly divergent when in the closed position shown, between which a roller 66 is retractably held by a toggle 67, 68, which in its turn is supported by a second toggle 70, 71. The link 71 is freely pivoted on the spindle 72 of an armature 73 mounted in a cage comprising soft-iron " cores " 75. The armature has radial arms 80- 83 which, when the toggles are locked, occupy the position shown relative to the cores 75. The link 71 has projections 711, 721, which lie between projections on the armature arms 80, 83. When current is switched on, the armature is attracted by the cores 75 and is rotated counter-clockwise with sufficient momentum to cause the breaking of the toggle 70, 71 with consequent breaking of toggle 67, 68, and thereby withdrawal of the jaw-locking roller 66, so that the load is released. Rotation of the armature is stopped by the magnetic attraction of the cores 75 and by a stop 85, as well as by a coil spring which tends to counterrotate it. Current is conveyed to the armature. winding through fixed spring contacts 78 and contacts in the face of an insulated block 77 on the armature. At the end of the release operation, the block 77 engages below the loop of the fixed contacts 78 and holds the armature in the rotated position. To free the armature so that it may be returned to the operative position, the stop 85 is pushed inwards by a plunger 851 and pushes against the armature arm 83 to start the counter-rotation. The toggle link 71 is brought to rest against a fixed stop 751. To effect release by hand, the stop-plunger 85 is pressed inwards and forces a pivoted arm 84 against the armature arm 82, thereby causing .counter-clockwise displacement of the armature and breakage of the toggles.

Title: Apparatus for the vaporisation of liquids
Inventor: EVANS ARTHUR JAMES
IPC: B01D3/42
Filed: 1959-03-07
Abstract: 882,878. Automatic temperature control systems. DISTILLERS CO. Ltd. March 4, 1960 [March 7, 1959], No. 7967/59. Class 38 (4). [Also in Group XXVIII] Vaporizing apparatus for a readily vaporizable liquid such as liquid carbon dioxide or liquid petroleum gases comprises a heating vessel 1 having an inlet port 2 for connection to a storage tank containing the vaporizable liquid and an outlet port 4 for connection to a gas delivery pipe 5, the heating vessel containing three heating elements 7, 8, 9 with an associated temperature responsive device 10, 11, 12 respectively, the temperature responsive devices controlling the supply to the heating elements. Whilst the vaporizer is idle, the liquid vaporizes until the liquid pressure is balanced by the gas pressure in the vessel 1. Opening of a valve 6 allows the gas to be used with a consequent further generation of gas in the vessel 1 with a concomitant drop in the temperature in the vessel. The passage of the liquid through the inlet port 2 causes a temperature responsive device to operate to close a switch 17 whereby the electric supply circuit is closed. The drop of temperature in the vessel 1 causes the temperature responsive devices 10, 11, 12 to operate in succession to close switches 13, 14, 15 respectively so that the heating elements 7, 8, 9 maintain the supply of gas. As the demand for gas diminishes, the temperature at the top of the vessel rises, whereupon the temperature responsive device 12 causes the heating element 9 to be switched off. A further reduction in demand will cause the heating element 8 to be switched off and so on. Other temperature responsive devices, to control the heating elements, may be placed in the delivery pipe 5. A fusible link 26 is provided adjacent the vessel 1 which link ruptures should the temperature of the vessel rise above a predetermined limit, whereupon a switch 25 opens to remove the electric supply from the apparatus. The heating means may be other than electric, such as for example, steam.

[Class 60] [Also in Group XXII] A portable power-driven rotary tool for drilling, tapping, sanding, grinding, polishing, &c. has the tool arranged transversely or at an angle to the axis of the motor which operates through gearing in a casing shaped to be held in the palin of the operator's hand with the fingers extending downwards towards a nose on the casing adjacent the tool chuck. In one form the machine comprises a cylindrical casing 2 containing a motor 1 and having attached at one end a brush and switch housing 3 and at the other end, by a screw-thread 11, a ring 12 carrying a bearing 10 for the motor shaft 5. A gear casing 4 is screwed at 14 to an internal boss on the ring 12 and carries bearings 18, 19 for the tool spindle 23 which is arranged at right-angles to the motor and is driven therefrom through gearing 22. A fan 6 on the motor shaft draws cooling air for the motor through holes 7 in the casing and discharges it through passages 8 in the ring 12 to the exterior of the gear case to cool it sufficiently for handling. The machine is adapted to be held in the palm of the hand, as shown in Fig. 10, and grooves 9 are provided in the gear case in line with the passages 8 to prevent these passages from being obstructed by the hand. A slot 33 at the bottom of the ring 12 directs air to the vicinity of the rool 13. An extension 15 of the gear case encloses the chuck and forms a safe abutment for the operator's fingers. The direction of air through the machine may be reversed. In a modification, the motor casing 53, Fig. 6, is screwed directly at 55 to the gear case 44, and the air ducts 43 are formed in the latter. The lower slot 45 is of considerable extent to allow the passage of air even if several of the ducts 43 are obstructed by the operator's hand. In a further modification, annular air ducts 68, Fig. 8, of large cross-section lead straight through the gear case 65, and the lower duct 66 communicates with an annular passage 61<1>.
