Filed: 1967-08-04
Abstract: 1,123,708. Stoppering. E. J. BOWLES (Continental Can Co. Inc.). 4 Aug., 1967, No. 35870/67. Heading B8T. A rotary-table screw or turn-on cap applying machine comprises a series of cap-engaging heads 112, 121, circumferentially arranged around the table, each head consisting of a high-speed spindle 70, 81 driving a cap-spinning head 112 which effects initial tightening of caps C on jars, &c. R, and a surrounding lowspeed hollow shaft cap-tightening assembly 50 driving through a limited lost-motion spring coupling 96 to a friction pad 121 which engages the caps. Input to the high-speed spindle assembly is through gears 82, 83, and to the lowspeed shaft assembly through gears 58, 60. The high-speed and low-speed spindle and shaft assemblies 70, 81; 50, 96 are journalled both for relative rotation and for relative axial movement. As the machine table rotates, cam follower rollers 52, 75 run over stationary cam surfaces 55, 76 to lower, &c. sequentially the cap-engaging heads 112, 121. Each high-speed capping head 112 incorporates a magnet 113 in its bottom face to hold a cap C before application to the jar, &c. R. If during final tightening a cap C jams on its jar, stops (104, 131), Fig. 3 (not shown), between the input and output of the lost-motion spring coupling 96, abut to prevent over-twisting of the coupling spring and ensure that the cap is screwed home. The torsion of the spring 96 in the lostmotion coupling may be adjusted.

Title: Television apparatus
IPC: H04N7/16
Filed: 1960-10-19
Abstract: 904,128. Television. HARNETT, C. R. Oct. 19, 1960 [Oct. 12, 1960], No. 35884/60. Class 40 (3). A conventional television receiver is provided with auxiliary apparatus (Fig. 1) which enables it to receive, at will, by operation of ganged switches 28 . . . 31, normal television signals from a local aerial connected to terminals 4, 5, free (i.e. " unscrambled ") signals transmitted over a cable 36 (switch arm 28 on contact 282) or, in the remaining three switch positions, " scrambled " signals from cable 36 which are " unscrambled " by apparatus 1 to render them suitable for reproduction by a conventional television receiver, a variable rate accounting meter apparatus 2 being brought into operation during reception on two of the " scrambled " channels to indicate the debt incurred. The third " scrambled " programme is transmitted by arrangement and does not actuate the accounting meter. The signals are " scrambled " by being transmitted (on cable 36) on carrier frequencies below those to which conventional television receivers respond and the apparatus 1 operates (when power switch 27 is closed) to bring these frequencies within the range of the receiver. Operation of switch 27 also energizes a synchronous motor 9 in the accounting meter 2 to drive a counter 16 which indicates the debt incurred when receiving two of the " scrambled " signals (switch arm 30 on contacts 303 or 304). For the first of these signals (switch arm 30 on contact 303 and switch arm 31 on contact 313) the meter 16 is driven at a rate determined by the ratio of gears 15 and 11 (see also Fig. 4) whilst for the second of these signals (switch arm 31 on contact 314) a solenoid 22 operates to cause a gear 12 to slide along shaft 10 so that its " teeth " 14 project through the plate 18 of gear 11 and thus double the rate at which the counter 16 is operated.

Title: Improvements in and relating to the electric control of systems comprising a plurality of similar devices
IPC: B65G60/00
Filed: 1937-12-30
Abstract: 508,544. Switching systems for consuming devices. GENERAL ELECTRIC CO., Ltd., COATES, H.J., and PRICE, A.'B. Dec. 30, 1937, No. 36096. [Class 38 (iv)] In a system comprising a plurality of feeders for feeding material, the operation of each feeder is controlled electrically, and the energization of each feeder control circuit is under the influence of a common master. control so that the number of operations of said feeders collectively in a given time is maintained below a predetermined value. An application to four tub tipplers feeding coal to a conveyer is described. When all four tipplers are at rest any one of them may be started by depressing a push button associated with it, thus energizing the operating coil of a contactor controlling the supply to a solenoid 3, 4, 5 or 6 and thereby removing a tub-stop to connect the tippler with its drive. If, say, push button 22 is depressed the operating coil of contactor 16 is energized from supply mains 1 and 2 through a number of normally closed contacts and contact 20 of a time delay switch which is common to the operating coil circuits of the contactors of all four tipplers. Operation of contactor 16 closes contacts 16a, 16b, 16c and opens a normally closed contact 16d, 16e, 16f in each of the other contactoroperating coil circuits. Contact 16b energizes solenoid 4 and starts the tippler. Contact 16a changes over with a make-before-break action so as to supply the operating coil circuit of contactor 16 independently of contact 20 of the time delay switch. Contact 16c energizes operating coil 19 on the time delay switch to open contact 20 instantaneously.. The opening of contacts 16d, 16e, 16f prevents the operation of other tipplers while push button 22 is depressed. When push button 22 is released, contactor 16 opens, thereby de-energizing 'solenoid 4 to return the tub stop, and contacts 16d, 16e, 16f are reclosed. Operating coil 19 on the time delay switch is also de-energized as a result of the opening of contactor 16 but closure of contact 20 is subject to a time delay so that further operation of any of the tipplers cannot take place till that time has elapsed.
