Abstract: 788,999. Level selectors for mine winches. BRITISH THOMSON-HOUSTON CO., Ltd. Jan. 24, 1956 [Feb. 9, 1955], No. 3893/55. Class 78 (5). A winder of the Koepe pulley type is adapted for operation at one of several levels by means of a plurality of cams 10, 11, 12, adapted to operate followers 46, to apply the brakes or other control, each cam being operated by the Koepe pulley (not shown) by means of a respective lost-motion mechanism 23, 28 or 29, and being provided with a respective counterweight 33, 34 or 35 to bias the cam. As shown, shaft 21, driven by the Koepe pulley, drives, through lost-motion device 23, shaft 16 carrying drum 30 having wound thereon cables 36, 40 carrying counterweight 33 and abutment 43. Also, drum 30 is rigid with and drives cam 10; the follower 46 of which is coupled to shaft 50 by clutch 53, rotation of shaft 50 operating the winch brake. Similarly, shaft 16 drives shaft 17 through lost-motion device 28 and shaft 17 is likewise provided with drum 31, counterweight 34, abutment 44, cam 11, and clutch 54 mounted on shaft 50. Again, shaft 17 drives shaft 18 through lost-motion device 29, and shaft 18 is likewise furnished with drum 32 counterweight 35, abutment 45, cam 12, and clutch 55 on shaft 50. The counterweights serve to bias together the two elements of the respective lost-motion devices so that one shaft follows the movement of the next. Operation. As the cage ascends, shaft 21 rotates, thus permitting each counterweight to lower itself so that shafts 16, 17, 18 follow the rotation of shaft 21. This continues, the abutments 43, 44, 45 rising till abutment 45 engages and is stopped by floor 20. Shaft 18 is now stationary. Shafts 21, 16, 17 continue to rotate till abutment 44 in its turn rises to engage floor 20. Shaft 17 is now stationary. Shafts 21, 16 continue to rotate till abutment 43 rises to engage floor 20. Shaft 16 is now stationary. All three cams 12, 11, 10 have now been fixed at different rotational positions. As the cage descends shaft 21 rotates in the opposite direction. First, shaft 21 rotates to engage lost-motion device 23 so that shaft 16 rotates, and cam 10 rotates to operate its follower 46. Second, shaft 16 continues to rotate and then engages lost-motion device 28 to cause shaft 17 to rotate. This operates its follower 46 through cam 11. Finally, shaft 17 rotates shaft 18, which operates its follower 46. If any one of these followers is clutched by its corresponding clutch to shaft 50, then the latter rotates and stops the winch, so that the level of stoppage is determined by the choice of clutch. Specifications 757,623 and 788,998 are referred to.

Abstract: 144,755. Armstrong, Whitworth, & Co., Sir W. G., Hadcock, Sir A. G., and Forster, G. Feb. 18, 1919. Machine g u n s ; cartridge magazines. -Relates to guns of the type in which a number of cartridges, carried by a rotatable holder situated within a drum, are conveyed one by one by a carrier into line with the axis of the gun and automatically pushed into the chamber of the gun by a rammer. According to the invention, the rotatable holder is carried by the gun mounting, and a pivoted carrier conveys the cartridges to the gun chamber, the breech-block, as it closes, turning the carrier back into position to receive a fresh cartridge and causing a partial rotation of the holder. Fig. 3 is a rear end elevation of the gun showing the drum 6 detachably mounted on a fixed bracket 8 and containing a rotary holder for five cartridges. The cartridges are conveyed in succession from the drum to a position in line with the bore by a carrier-arm 14 pivoted on a shaft 9 and forced to the position shown, against the action of a spring 16, by the closing of the breech-block 5. When the gun recoils, the carrierarm bears against the side of the gun and a projection 15 on the breech-block engages the forward extension 20 of a finger 19 on the carrier, thereby cocking a rammer spring 21 mounted in a casing 17. As soon as the spring 21 is held cocked by a pawl 22, the extension 25 of the finger 19 rubs over a surface 27 and moves the finger behind a cartridge in the carrier. When the gun returns to firing position with its breech open, the carrier swings inwards, the rammer spring 21 is released by the contact of a pawl 22 with a fixed projection 28, and the cartridge is rammed home. The breech-block is released as usual when the cartridge meets the extractors, and pushes the carrier back to the position shown, a pawl 29 meanwhile engaging teeth 13 to rotate the cartridge-holder in the drum and bring a fresh cartridge into the carrier. The carrier has a circular projection 30 engaging with teeth 12 to prevent improper rotation of the holder. Instead of changing the drum, fresh cartridges may be inserted through a door 11.

Title: Method of and apparatus for testing for and removing faults in coaxial electric cables
IPC: G01R31/02
Filed: 1937-02-12
Abstract: 474,724. Detecting faults ; laying cables. STANDARD TELEPHONES & CABLES, Ltd. Feb. 12, 1937, No. 4300. Convention date, May 1, 1936. [Classes 36 and 37] In order to test a coaxial conductor for faults caused by slivers or hair-like projections of copper extending between the inner and outer conductors, a condenser is charged to a predetermined potential and discharged through a high resistance into the conductor. A slow decrease of potential indicates a sound conductor, a sharp decrease indicating a fault. In the latter case the fault is burnt out bv applying the charged condenser directly to the coaxial conductor. A battery 10 of dry cells is connected through switches 11, 12 to the primary winding of a spark coil 14, the secondary winding of which is connected through spark gaps 15 across a condenser 19. The unsymmetrical secondary voltage is rectified by the spark gaps and charges the condenser 19. Each spark gap 15 is formed between a fixed point 17 and a movable point 16, the movable points being mounted on insulating blocks 18 attached to a plate 38 pivoted at 39. The condenser 19 may be replaced by a number of condensers in series, parallel, or series-parallel. An electrostatic volt-meter 20 is detachably connected across the condenser 19. One terminal of the condenser 19 is connected through a three-position switch 21 to a testing jack 23, the other terminal being connected to a ground jack 25, a two-position switch 35 being connected so as normally to short-circuit the jacks 23, 25 in order to protect the operator from shock whilst connecting the apparatus. The switches 21, 35 are of the mercury contact types. A flexible cable 30 having plugs 34 and clips 26 connects the inner conductor of the coaxial cable 33 to the jack 23 and the outer conductor to the ground jack 25. The control apparatus may be mounted on a panel hinged to form one side of a box containing the remainder of the apparatus and so arranged that the switch 11 is opened when the lid is opened. In making a test the spark gaps 15 are adjusted to give the desired condenser charge, the switch 21 is placed in the " charge " position shown in which the condenser is disconnected from the test jack 23, and the switch 12 is closed. When the condenser is charged to the desired voltage the switch 12 is opened and the switch 21 moved to the " test " position, in which the condenser is connected to the jack 23 through a high resistance 36, the switch 35 being open. If a fault is indicated the switch 21 is moved to the " discharge " position, in which the condenser 19 is connected directly to the jack 23, thereby fusing the copper slivers constituting the fault.
