Title: Improvements in or relating to splitting, skiving or like machines
IPC: C14B1/14
Filed: 1921-05-31
Abstract: 185,214. British United Shoe Machinery Co., Ltd., and Gouldbourn, J. May 31,1921. Splitting, &c.-In apparatus for splitting and skiving leather and the like of the type in which the leather &c. is fed to a fixed plane knife by feed-rolls, as described in Specifications 21977/03, [Class 76, Leather], and 18752/12 for example, and in which a draw cut is obtained by movement of the feed-mechanism across the line of feed as the feed progresses, as described in Specification 2465/72, [Class 76, Leather], the feed-rolls are given a comparatively rapid transverse vibratory movement by reciprocating means external to their bearings. In the form shown, the machine is of the type described in Specification 21977/03, [Class 76, Leather], and comprises feed-rolls 2, 4 geared to a power driven shaft 10 and rotating in bearings 7, 9 of which the latter is formed, as usual, in spring-pressed levers 11 which allow movement of the lower roll towards and away from a fixed knife (not shown). A belt-driven pulley 12 loose' on the shaft 10 carries a member 13 formed with a cam-track 14 engaged by a roller 18 on a lever 20 pivoted at 22 to lugs 23 on the machine frame. A second roller on a member rigidly connected to the frame causes reciprocation of the pulley 12 and member 13 as they revolve so that the roller 18 receives a throw of double the normal throw of the cam-track. The lever 20 is formed at'its other end with a projecting sleeve 26 which houses a pin 24 bifurcated at its upper end to engage a groove in the shaft of the upper roll 2. The sleeve 26 also forms a bearing for a barrel-shaped roll 28 running in a correspondingly shaped track in a disc 30 fixed to the shaft 5 of the lower roll. Oscillation of the lever 20 thus causes both feed-rolls to reciprocate in unison in their bearings. The cam-track 13 is so designed as to give quick reversal of movement of the feed-rolls from one direction to the other and the throw of the cam-track and the speed at which it is driven are so related that the average axial rate of movement of the feed-rolls is at least as great as their peripheral speed. The Provisional Specification refers to a construction in which the oscillating lever is coupled to one only of the feed-rolls which are coupled for joint movement by a rib and groove.

Title: Improvements in or relating to electric remote-control arrangements
IPC: H05B37/02
Filed: 1954-05-21
Abstract: 753,629. Control systems for stage lighting. SIEMENS-SCHUCKERTWERKE AKT.-GES. May 21, 1954 [May 22, 1953], No. 15061/54. Class 38 (4). Electromagnetic clutches 1, 2 for actuating a stage-lighting dimmer are remotely controlled from the stage switchboard by a switch 3 and from an auxiliary point, say the auditorium, by push-buttons 15, 16, interference between the two control systems being avoided by a relay having contacts 5 in the feed circuit to the switch 3 and its winding energized over back contacts of the push-buttons, whereby the feed to the switch 3 is interrupted when either of the push-buttons is operated. Rectifiers 9, 10, 13, 14 prevent the flow of undesired currents. When the control of a number of dimmers is involved, the relay 5, 6 may operate to inhibit the control of only some of them from the switchboard.

Abstract: 663,484. Coke ovens. ALLIED CHEMICAL & DYE CORPORATION. June 7, 1949 [Aug. 4,1948], No. 15077/49. Class 51 (ii). A rich gas-fired underjet coke oven battery has, spaced along the battery supporting mat 10, massive walls 16 defining coking chambers 25 and regenerators 26, each wall 16 including in its upper portion heat-transmitting walls 18 on opposite sides thereof, and two rows 19 and 20 of vertical heating flues enclosing a massive refractory wall 22 which with liners 23 is at least four times the width of the heat transmitting walls. On the pusher side of the battery each row of heating flues has an outer group of flues 40-47 communicating by a horizontal top flue 48 with an inner group of flues 49-56 and on the coke side of the battery an outer group of flues 57-62 communicating by a horizontal top flue 63 with an inner group of flues 64-70. Disposed below each oven chamber 25 is a row of regenerators 26 comprising outer regenerators 27 connected by a sole flue 29 to the respective outer groups of heating flues and an inner regenerator 28 connected by a sole flue 30 to the inner groups of beating flues. If desired, a pair of inner regenerators 28 may be used, each connected to an individual group of inner heating flues or the regenerators may be divided along the median plane so that each row of heating flues is connected to a separate row of regenerators. The heating flues are provided with alternate high and low burner nozzles 74 and 73 supplied with coke oven gas from pairs of mains 76 in the basement 14, each burner supply pipe having an individual flow regulator of the type disclosed in U.S.A. Specification 2,199,961. Alternate mains 76 supply the inner and outer groups of heating flues and are themselves supplied alternately through three-way valves 80 with coke oven gas from the main 78 or de-carburizing air from the main 83. Clean air of predetermined humidity may be admitted into the basement 14 through the channel 87 and reversing valves 31 at the coke side of the battery supply air to the sole channels 29 and 30 or exhaust waste gases into the flue 32. The robust construction of the dividing walls 16 enables coal with as low a volatiles content, as 18 per cent to be successfully coked. U.S.A. Specifications 2,155;954 and 2,407,356 are also referred to.

Abstract: 1,029,666. Lubricating. DAIMLER-BENZ A.G. April 9, 1965 [April 11, 1964], No. 15192/65. Heading F2A. In an electrically-driven centralized lubrication installation on a motor vehicle, a warning-signal 18 is connected in parallel with a fuse 7 in the circuit of an electric motor 8 which drives a grease pump 12. In an embodiment, the pump 12 may be actuated manually by a knob 15 or by driving mechanism 2 of a tachometer 1, once every 100 kilometers for example. This is effected by a cam 14, on the " tens "  dial 3<SP>1</SP> of the counting mechanism 3, closing contacts 5, one of which is connected by a lead 17, via the fuse 7 and an ignition-switch 19, to a battery 6; and the other of which is connected by a lead 17<SP>11</SP> to the motor 8, a further lead connecting the motor to the battery 6. The warning-signal 18 is connected, in parallel with the fuse 7 and the contacts 5, to the battery 6, via a lead 17<SP>1</SP> and the ignition switch 19; and is connected, via a resistance 20, to the battery 6. In use, if the fuse 7 is destroyed, electricity passes along the lead 17<SP>1</SP> to operate the warning signal 18 and returns to the battery via the resistance 20.

Title: Device for counting leaves or sheets in a pile or packet and for indicating the groups of counted sheets
IPC: G06M9/02
Filed: 1951-07-03
Abstract: 712,761. Counting-apparatus. ROSSWALL, A. E. Oct. 3, 1952 [July 3, 1951], No. 15796/51. Class 106 (1) Apparatus for counting leaves or sheets in a pile or packet includes means for inserting, after each batch of a predetermined number of sheets, a marking slip. The counting apparatus shown is that described in Specification 557,086, in which the operations of a mechanically driven suction blade 29 and stripping arm 30 are counted as they successively engage and depress the comers of the sheets 11. The marking slips are cut from a roll 31 of stiff paper. The web passes over rollers 33, 34, through a guide 35, between feed rollers 36, 37 and through a further guide 54 to the cutting knives 56, 57. The roller 34 is carried by a cam-operated lever 38 which prior to a feeding operation forms a loop in the web. The feed rollers 36, 37 are geared together and to a shaft 44 carrying a ratchet wheel engaged by a pawl 48 carried by a tubular shaft surrounding the shaft 44 and fast with a gear 49 meshing with a rack 50. A snail cam produces a sudden movement of the rack, by an amount determined by an adjustable stop 67 for the rack lever, after each batch of a predetermined number of slips has been counted, so as to project the end of the web into the gap formed in the pile of sheets by the suction blade 29. A brake (not shown) acting on the spool carrying the paper roll prevents over-feeding. The knife 56 is then operated against a spring 66 by a cam-controlled arm 58. The counting- apparatus and slip-inserting means are mounted on a carriage movable by a motor up and down a frame pivoted at its base about a horizontal axis. According to the Provisional Specification, the final paper guide 54 is rocked by the arm 58 adjacent to a single stationary knife. Specifications 688,251 and 710,275 also are referred to. Reference has been directed by the Comptroller to Specification 557,086.
