Title: Electrical power control arrangement
Inventor: MATTHEWS BENJAMIN HART
IPC: H01C10/38
Filed: 1969-01-31
Abstract: 1,261,244. Variable resistors. LUCERNE PRODUCTS Inc. 31 Jan., 1969 [1 Feb., 1968], No. 5485/69. Heading HIS. A resistance control arrangement, e.g. for a motor M, Fig. 15, includes switches 48, 48a and 52, 52a, 52b provided with bridging contacts 60, 62 operable by a control (trigger member 13, Fig. 7) which also operates the moving contacts of a variable resistor arrangement 78a, 78b, 78c. Variation of the resistance when switch contacts 48, 48a and 52, 52a are interconnected may vary the ignition point of a neon tube 98, thus varying the firing point of a controlled rectifier 124 through which capacitor 96 discharges to energize the motor in alternate half-cycles. Instead of 124 a device ("triac", Fig. 15A, not shown), conducting in both directions on firing, may be used. The resistor may be a carbon layer 74a, Figs. 14 and 14B, divided by grooves 78, 81, 79, the layer portions 78a, 78b being contacted by projections 100a on a movable carrier member 72 guided by its flexible arms 99a (which press against the inside of the casing) and operated through a projecting part 100b by the trigger 13, Fig. 7. A trimmer resistance device is provided by a contact 104 which is movable (by an arm 82) over part of the resistance layer and thus provides a variable resistance 78c in parallel with the resistance part 78b. When the trigger is in the "off" position, the bridging contacts 60, 62 rest on projections 69 of the insulating casing (44, Figs. 11 and 12, not shown). When the trigger is moved these contacts move on to the stationary contacts 48a, 52a. When the trigger is in the "full-on" position, the contact 62 moves on to stationary contact 52b causing the speed control circuit to be by-passed. The trigger may be locked in this position by a spring-biased pin arrangement (Fig. 13A, not shown).

Title: Hydraulic pressure generating and applying device
IPC: B66F3/24
Filed: 1945-03-06
Abstract: 588,651. Hydraulic presses. PAGE, H. E. March 6, 1945, No. 5572. Convention date, March 6, 1944. [Class 69 (ii)] Hydraulic pressure generating and applying device comprises a block 1 containing a number of cylinders 3, 4, 5 carrying pistons connected to work supports 50, 51, one piston being reciprocated by levers 52, 53 to pump liquid from a reservoir 30 to the pressure cylinders 4, 5. The block may reciprocate on stationary pistons or vice versa. Work may be compressed or tensioned between the block and supports 50, 51. Connection between the pump and cylinder 4 is controlled by valves 60, 61, while similar valves 62, 63 control the connections between cylinders 4 and 5. These valves each comprise a suction valve 77a which may be held off its seat by a hand-operated cam 120 and a discharge valve 86 held seated by a spring 105. To move block 1 left, pump 3 is reciprocated by lever 52 and draws liquid into the cylinder from the reservoir through suction valve 77a of control valve- 60. Liquid is trapped in the cylinder and moves the block until the work is contacted and pressure rises sufficiently to open discharge valve 6 to permit liquid to pass to working cylinder 4. Suction valves of valves 61, 63 are meanwhile held off their seats by manual actuation of their controlling cams. Further rise of pressure causes discharge valve 86 of valve 62 to open and pass liquid from cylinder 4 to cylinder 5. Additional manually operable valves 114, 115 may be set to pass pump discharge to either end of cylinder 4 or to enable both ends of the pump to discharge to one end of the cylinder. Relief valves 93, 98 are provided in each of the valves 60 ... 63.

Title: Improvements in Wrapping Machines
Inventor: PARKER MATTHEW
IPC: B65B35/24
Filed: 1968-02-06
Abstract: 1,198,021. Conveyers. ROSE FORGROVE Ltd. 10 Jan., 1969 [6 Feb., 1968], No. 5835/68. Heading B8A. Apparatus for feeding articles, e.g. chocolate bars 100 to a wrapping machine (not shown) comprises reciprocating feed bars 1-3 and reciprocating leading and trailing grippers. The grippers, having closed on the first two articles 100, advance the articles by different amounts to provide a definite spacing between them, after which the articles are released and the grippers returned to grip another pair of articles. Feed bars. The centre bar 2 receives substantially horizontal movement from a cam 6, levers 7, 9, 10 and a link 8, and a small vertical movement from a cam 19, levers 16, 17, 20, 21 and links 22, 23. The bars 1 and 3 are given a substantially horizontal movement only by a cam 26 and a. lever 27, these bars being supported at their leading ends by a carrier 28 having pillars 29 and, at their rear ends, by pillars 30 on a rocking lever 33. The bars 1, 3 begin to decelerate near the end of their leftward movement at the moment when the bar 2, having accelerated up to speed in its leftward movement, comes level with the bars 1, 3, after lifting slightly. Continuing to be lifted, the articles are carried leftward on the bar 2 and the bars 1. 3 return to the right, below the articles. Grippers. The trailing gripper comprises a gripper jaw 36 pivoted to the centre bar 2 which acts as a co-operating lower gripper when a lever 37 is permitted by a cam 38 to descend under the action of a spring 63 and to allow the jaw 36 to descend under the action of a spring 41. At the moment it is gripped, the article 110B is touching the article 100A which is in contact with a vertically movable stop 53 and gripped by the jaws 42, 43 of the leading gripper 101. These jaws are interconnected by meshing gear segments 143, 144 and are controlled by a cam piece 49 on the lever 37, a runner 50 on the jaw 42 and a spring 51 between the jaws. Horizontal movement of the leading gripper is caused by the cam 6 through the lever 7, a link 44 and a lever 45. Since the trailing gripper is also operated by the cam 6, both grippers move together but, due to differing lever ratios, the leading gripper moves further than the trailing gripper and spacing between the articles 100A, 100B results. The leading article 100A is pushed from a platform 52 by a face 142 on the jaw 42, and is fed to the wrapping machine by a chain conveyer 56. Articles having irregular bases may require the bars 1 and 3 to have vertical movement as well as the bar 2. The apparatus may be used to feed groups of articles and there may be provision for counting articles. A constantly moving belt may be used in place of the feed bars.
