Title: Improvements in or relating to reel mechanism particularly for aircraft antennas
IPC: H01Q1/30
Filed: 1940-11-21
Abstract: 544,684. Winches. LEAR AVIA, Inc. Nov. 21, 1940, No. 16757. Convention date, Dec. 15, 1939. [Class 78 (v)] A reel-mechanism, particularly for aircraft antennae, comprises a cable &c. reel 32 mounted on a shaft 19 driven through worm gearing 7 and spur gearing 14, 15 by an electric motor 2. The worm 7 is carried slidably but non-rotatably by a spindle 5, on which are mounted, also slidably, two switch-button operating cams, 9,10 positioned respectively by a weak spring, 13 and a strong spring 12. When a manual switch is operated to start the motor 2 in the paying-out direction, the pull on the cable due to its attached weight or drag-sock tends to keep the worm 7 up against the cam 9 which is supported by the spring 13. When the cable is fully unwound the pull of its swivel terminal connection to the reel tends to reverse the direction of rotation of the latter and to force the worm 7 up against a bearing sleeve 6. This allows the spring 13 to push along the cam 9 to follow up and so operate the button of switch 20 to deenergise the motor 2. Should the cable snarl or foul the fairlead during unwinding the forward pull on the shaft 19 would similarly cease and the cam 9 be moved to stop the motor. If the manual switch be moved to the motor-reverse position, the cable will be wound in till the sock or ponder weight jerks it to a standstill at the end of the wind, and this will join the worm wheel and force the worm 7 toward the cams 9, 10, pushing these under the drive of the motor till the cam 10 presses in the button of switch 8 and stops the motor. The outward pressure of spring 12 on the worm 7 maintains tension in the wound-up cable. The reel 32 has a central aluminium core 31 keyed to the shaft 19, and is held in place by a snap slide assembly 30 engaging a groove in the shaft end. The flanges 29 have inturned lips to guide the cable 56 on to the middle of the reel rim. A warning light may be switched on during the time the cable is partly or wholly payed out, and a resistance may be included in one of the motor fields to equalise the motor speeds in both directions. The cams 9, 10 may switch in the non-operative field when the motor is stopped to produce a braking E.M.F. In a modification the sliding cams are replaced by spring-controlled discs.

Filed: 1927-06-23
Abstract: 273,320. Akt.-Ges. Brown, Boveri, et Cie. June 23, 1926, [Convention date]. Controlling consuming devices.-A three-phase furnace is fitted with two sets of resistances G', G<2> and with elements A<1>, A<2> responsive to the temperatures of the surface and the interior of the charge respectively, and operating switches K<1>, K<2> each of which has three different positions. Initially G<1>, G<2> are delta-connected by switches S<1>, S<2>. On approaching the desired surface temperature relay R<1> is closed to operate S<1> to change the connection of G' from delta to star. The star-connection is closed through an induction regulator J. On reaching the desired temperature relay R<2> operates S<2> to produce a similar change in the connection of G<2>. If the surface temperature rises further the motor M operates switch S<4> to cut out G<2>. In the initial position of K<2> the switch S<4> is closed by motor M. When the interior of the charge reaches the desired temperature G<2> is cut out. If the internal temperature rises further relay R' is closed with consequent opening of the switch S<3> in the supply circuit.

Title: Explosive composition
IPC: F02B3/06
Filed: 1965-04-21
Abstract: An explosive composition, resistant to the development of charges of static electricity, comprises ammonium nitrate, an oleaginous fuel, and a product of the reaction of a mixture of secondary and tertiary aliphatic amines with a mixture of high molecular weight fatty acids. Optionally a finely divided metal or metalloid may be present, for example Al, Mg, B, or Si, or alloys thereof.  Sodium nitrate may replace part of the ammonium nitrate. The fuel may be diesel oil, fuel oil, vegetable oil, petroleum grease or wax, or a partially nitrated derivative of benzene, toluene, xylene, or naphthalene. Calcium carbonate, sodium carbonate, ammonium carbonate, triethylamine, or piperidine may be added as an acid acceptor to absorb any free nitric acid in the ammonium nitrate.  The ammonium nitrate may be pretreated with an antisetting or waterproofing agent, e.g. kieselguhr, kaolinite, the sodium salt of a mixture of methyl and dimethyl naphthalene sulphonic acids, or calcium stearate.  The explosives are useful in underground blasting operations where explosive is forced into a borehole through a tube or hose.

[Class 98 (i)] In a collapsable camera, a single externallyoperated yoke element releases the bed braces of the hinged bed when the camera is extended and acts also as a latch to retain the camera bed in the closed position. The bed 2 of the camera is supported in its extended position by braces 4, which have slots 7 with hooked ends 8 engaging pins 9 on the camera wall. A yoke member 10 has side plates 13 pivoted at 14 to the camera walls, lugs 15 bearing on the front edge of the braces 4. A slide 11 operated by a push-button 12 and guided by a pin and slot. 16, 17, has a nose 19 which coacts with a similarly inclined surface 20 on the yoke member 10 so that, when the push-button is actuated, the yoke member is tilted to bring the pins 9 into the slots 7 and allow the camera to collapse. When the yoke member is tilted, lugs 22 are moved out of the way of pins 23 on the camera bed ; but if the push-button is released, a spring 25 brings an inclined surface 26 into engagement with a surface 21 on the yoke member to tilt the latter and lock the bed in the closed position. The bed is released by actuation of the push-button 12. The camera is self-erecting by the action of a pin 36 in the curved slot 35 of a pivoted link 32. The front may be of the pull-out type.

IPC: B21C37/22
Filed: 1950-07-06
Abstract: 693,009. Making heat exchangers. BROWN FINTUBE CO. July 6, 1950, No. 16905/50. Classes 83 (ii) and 83 (iv). [Also in Groups XI and XIII] Brazing.-A method of making heat exchange tubes comprises applying surface-extension elements 2 to the exterior surface of a supporting tube 1, introducing this structure into a closelyfitting outer tube 10, supplying bonding metal to the contiguous surfaces of the elements 2 and the outer tube 10, expanding the supporting tube 1 to provide firm contact between the outer tube and the elements 2 and then fusing the bonding metal. The elements 2 are of channelsection having longitudinally-extending fins 3 and 4 joined by a web 5 which is bonded to the supporting tube 1. The fins have flanges 7 and 8 which may be of arcuate cross-section. The flanges and/or the interior surface of the tube 10 are coated with the bonding metal, e.g. copper and its alloys, silver, solder, tin, &c. The tube 1 with the elements 2 attached, is inserted within the outer tube 10 and expanded by a mandrel. The bonding of the outer tube to the elements 2 is effected by passing the assembly through a high-frequency electrical induction block 14 and a stationary torch 16 located within the tube 1 in juxtaposition to the block 14 ensures an even expansion throughout that portion of the assembly within the block. Fuel gas is fed to the torch by a feed-pipe 17 which leads to peripheral ports 19a and 19b in a chamber 18. Close-fitting caps 21 are mounted on each end of the outer tube 10 and are held together by the rods 26. A reducing gas, e.g. hydrogen or partially burned natural gas, is admitted to the tube through an opening 22 in the cap 21 and a flexible conduit 24. Longitudinally extending channel members may be applied to the exterior of the outer tube 10 and these members may have flanges similar to the elements 2 so that the whole assembly may be inserted in another outer tube 31, as shown in Fig. 7, so forming a series of concentric tubes separated from each other by annular passages. In another embodiment external annular fins 49a, 49b, 49c, Fig. 9, are applied to the tube 10 either singly or in groups. As hitherto the bonding metal is applied to the elements 2 and to the inner portions of the fins and after assembling and expanding the inner tube 1 the bonding is effected by heating in an electric furnace. The fins may have a pentagonal, hexagonal, octagonal, &c. periphery and may be paired together by an outside web between adjacent fins. Specification 670,574 is referred to.
