Title: Novel duplicating sheets
Inventor: NEWMAN DOUGLAS ALEXANDER
IPC: B41M5/025
Filed: 1961-06-22
Abstract: A "carbon paper" sheet releases oil or wax or both from a porous, spongy synthetic resin layer (see Division D2) In the examples this layer is formed by coating sheets with a solution of the synthetic resin and oil or wax in a mixture of toluol and ethyl acetate The solutes are: (Example 1) a soft copolymer of vinyl chloride and acetate, mineral oil and microcrystalline wax; (Example II) polyvinyl butyral, mineral oil and polyethylene glycol wax; and (Example III) a soft copolymer of vinyl chloride and acetate and lanolin.ALSO:An assembly of sheets comprises a donor sheet which releases oil or wax or both under the effect of heat or imaging pressure and a copy sheet with a coloured foundation and a coating thereon that is opaque but becomes transparent when impregnated with the wax or oil so that the coloured foundation shows through.  The oil or wax or both is released from a porous, spongy, synthetic resin layer, carried by the donor sheet.  The opaque coating comprises calcium corbonate.  The donor sheet may comprise a foundation sheet of paper, cellulose acetate or polyvinyl chloride.  The synthetic resin of the donor layer may be polyvinyl chloride, polyvinyl fluoride, polyvinyl acetate, a vinyl chloride-vinyl acetate copolymer, polyvinyl butyral, polyacrylic acid, polystyrene, polyvinylidene chloride, polyethylene, polypropylene, a polyurethane or a polyamide.  The wax or oil is a non-solvent for the synthetic resin; examples are polyglycols, cetyl alcohol, microcrystalline wax, ouricoury wax, beeswax, montan wax, carnauba wax, lanolin, tallow, petrolatum, hydrogenated cottonseed oil, naphthenic mineral oil, neatsfoot oil, refined rapeseed oil, cottonseed oil, peanut oil, castor oil, olive oil and sperm oil, or mixtures of waxes and oils.  The synthetic resin and wax or oil may be applied as a solution in a common solvent, or as an organosol or plastisol.  The copy sheet may be of paper or synthetic film and coating of calcium carbonate may be bound by sodium aliginate, carboxymethylcellulose, gelatin or gum arabic.  In a modification a number of sheets with a donor layer on one side and a copy layer on the other may be sandwiched between the donor and copy sheets, each of the donor layers in the assembly being next to the copy layer of the next sheet.

Title: Improvements in or relating to electric slowly acting relays for use with automatic circuit breakers for protecting electric circuits
IPC: H02H3/027
Filed: 1926-09-14
Abstract: 258,588. Siemens - Schuckertwerke Ges. Sept. 15, 1925, [Convention date]. Protective arrangements; induction motor relays; differential switches.- An inverse time-lag, differentiallyactuated relay for the selective isolation of an overloaded section comprises two induction-motor-meter elements of known construction which close the relay when they rotate at different speeds, the time elapsing before the closure is effected being dependent upon the difference of speed. In the arrangement shown, one induction meter is driven by electromagnets 33, 34 energized from a current transformer 14 in the line section to be protected and its disc 12 drives through bevel gearing one crown wheel 16 of a differential gear. The other crown wheel 15 of the gear is driven by a constant speed induction disc 11 energized from a constant source 13 (which may be a constant voltage derived from a part of the line). Instead of the induction disc a clockwork motor driven disc may be used. The floating intermediate pinions 18 are connected with the switch actuating lever 21 and when, on overload, the speed of the disc 12 exceeds that of the other disc the lever 21 is carried round at a speed dependent on the overload until it brings together the contacts 23 in the tripping circuit of the main circuit-breaker 25. The switch actuating arm 21 may be journaled eccentrically on its shaft 19 under the control of a spring so that in approaching the contacts it first engages a stop from which, by further movement, it is released with a quick action due to the spring. When the overload falls off so that the disc 11 rotates faster than the disc 12, the relay 23 is not immediately opened as some idle movement of the shaft 19 is necessary before the spring is strained to cause the actuating lever to follow. In this way a time-lag is imposed also on the resulting movement.

Patent GB-759700-A (GB)
Title: Improvements in and relating to electric feeler control systems for machine tools
IPC: B23Q35/12
Filed: 1952-09-15
Abstract: 759,700. Electric control systems. SOC. AUTOMATA. Sept. 15, 1952 [April 17, 1952], No. 23124/52. Class 40(1) In a feeler-controlled copying machine tool the feeler actuates a series of contacts in succession as its deflection from a neutral position increases, and through control relays governs the rectilinear movement of a table and the rotary or rectilinear movement of a workpiece and pattern support relative to the table. In addition, the feeler head may be subject to a further movement under control of its deflection to provide for three-dimensional working. As shown, Fig. 1, a longitudinal slide 1 driven through a reversible clutch 10, carries rotary tables 2, 3, 4 driven together in either direction through a clutch 9. The table 2 carries a pattern 5 adapted to be explored by a feeler 6 which controls the energization of the clutches so that cutters 14, 15 cut internal and external copies 7, 8 from the workpieces mounted on the tables 3, 4. The feeler head is mounted on a slide 11 for initial adjustment relative to the cutters 14, 15. The feeler, Fig. 10, comprises a shaft 54 universally mounted at 55 and having a pin 56 at its upper end engaging a conical recess in a vertically reciprocable member 58 so that as the deflection of the feeler from the neutral (vertical) position shown increases, a series of contacts are closed in succession, e.g. as described in Specifications 759,697, 759,699, 759,701 by the member 58 to control relays R<SP>1</SP>...R<SP>4</SP> in appropriate combinations to energize the clutches 9, 10, and cause the feeler to explore the entire pattern. The number of contacts controlled by the feeler and hence the number of feeler control "orders" may be varied to alter the exploration of the pattern according to its shape and a selector switch may be used (Fig. 12, not shown) to determine the method of exploration. A three-dimensional pattern, Fig. 11, may be copied, the pattern in this case being explored spirally. The feeler in such a case, is also capable of axial movement. Speed control of the longitudinal and/or the secondary drive of the pattern and work carriers may be effected by means of a continuously driven insulating cylinder 67, Fig. 19, having conducting segments, the clutch 10, e.g. being energized directly for high speed, through brushes 68, 70 for normal speed and through brushes 68, 71 for low speed. The brushes 70, 71 may be adjusted axially of the cylinder, and when operative, cause the clutch to be energized in pulses the durations of which are determined by the width of the conducting segments of the axial position of the operative brush.

Title: An improved method of transmitting pneumatic power in a closed circuit
IPC: F16H39/01
Filed: 1926-09-20
Abstract: 258,869. Doctorics, B. Sept. 26, 1925, [Convention date]. Void [Published under Sect. 91 of the Acts]. Actuating pumps by fluid-pressure motors; regulating compression. - The flow and return circuits of a closed circuit power transmission device are each maintained at a pressure above atmospheric. An auxiliary compressor supplies air to compensate for leakage, and is put out of action automatically when not required. The main compression may be effected in the crank case of an internal-combustion engine. Fig. 1 shows a regulator in which a rod 22 is actuated to hold the auxiliary pump suction valves open by a lever 17 connected to the rod 22 and to rods 14 actuated against spring pressure by diaphragms 5 subjected to the pressure in the flow ani return circuits respectively. Fig. 4 shows part of an eight-cylinder engine in which the cranks are at 90‹ and pairs of cranks are enclcsed in a common compression casing. The pistons are also formed with flanges 61 which give an additional compression in spaces 66. The spaces 66 of one pair of cylinders may be connected by passages 77, 78 with the crank casing of the next pair. Fig. 6 shows a compound main compression plant in which the. air in the interstage pipe 40 is maintained at the desired pressure by the auxiliary pump 50 in which inlet ports 51 are provided, controlled by the piston 49. Fig. 7 shows a compressor in which air is compressed in the cylinders 80 below the motor pistons 85 and in the cylinders 81 above the pistons 83 which are rigidly connected to the pistons 85. The compression spaces of adjacent cylinders are connected by passages 91, 93 in the manner shown. These passages are continued as passages 95, 96 controlled by slides 100, 101 on a rod oscillated through linkage controlled, through an adjustable rod 113, by the pressure in the return circuit 112.
Patent GB-1106471-A (GB)
Title: Shear
Inventor: GREENBERGER JOSEPH IRWIN
IPC: B23D15/14
Filed: 1964-06-04
Abstract: 1,106,471. Shearing. UNITED ENGINEERING & FOUNDRY CO. 18 May; 1965 [4 June 1964], No. 23287/64. Heading B3W. A flying shears consists of a reciprocating cutter which is mounted on a parallelogram linkage to produce the flying motion. In a first embodiment (Fig. 1) the cutting mechanism is carried by a cross-bar 19 which is suspended below the material to be cut 8 by parallel links 15, 16. A frame 23 on the cross-bar 19 carries a fixed blade 25 which moves towards the material S during the swinging movement of the shears. A movable blade 28 is carried by a cylinder 26 which is movable over a fixed piston 30, pressure fluid being supplied along a conduit 33 to raise the blade 28 when the blade 25 is adjacent the material S. The blade 28 is returned by piston and cylinders 34, 35. The swinging motion is produced by a ram 42 which is driven through a rack 43 and pinion 45 which is connected through a clutch (not shown) to the drive shaft of the feed roller 11 so that shears move at the same speed as the material S. The clutch is engaged to operate the shears by a photoelectric cell system. The shear is returned to its starting position by a piston and cylinder 56. In a second embodiment (Fig. 4) the crossbar 66 carrying the cutting mechanism is suspended above the material S by parallel links 64, 65 pivoted to a frame 57, 58, 59. A fixed blade 81 is mounted on the underside of the cross-bar 66 above the material S. The cross-bar 66 is formed with guides 69 in which slides a block 68 carrying a movable blade 72 below the material S. The blade 72 is reciprocated by a double acting piston and cylinder 78 mounted on the upper side of the cross-bar 66 and connected to the block 63 by connecting rods 75. The swinging motion is produced by a double acting piston and cylinder 85 which is supplied with pressure fluid from a pump (not shown) which is geared to the drive of the feed rolls in such a way that the shears move at the same speed as the material S. During the swing- ing movement the cutting mechanism is guided by a tongue 83 which slides in a U-shaped guide 82.
