Abstract: 1,050,584. Selective signalling systems. UNIMATION Inc. Feb. 24, 1964 [Feb. 25, 1963], No. 7552/64. Heading G4H. In a digital servo system, the position of a movable output member 20, Fig. 1 (not shown), is represented in reflected binary code by signals produced by heads 38 which are movable over a fixed coded pattern 42, and a direction control signal is derived by logic circuits 26 as a result of a direct comparison of a reflected binary command code on leads A1-A7 with the present position code on leads B1-B7. The correct direction signal is obtained by comparing corresponding digits A1, B1 &c., taking the direction indicated by the most significant pair of mismatched digits and reversing this direction a number of times equal to the number of binary 1 coincidences in the more significant pairs of digits. The circuits 26 are also arranged to produce successive slow-down signals as the movable member 20 approaches the desired position, these signals being produced by comparison circuits for various pairs of digits and signifying that member 20 is not more than one bit of the corresponding digit track from the desired position. The signals cause corresponding relays to be de-energized to insert extra resistance in the supply circuit for a solenoidoperated valve 31. The command signals may be derived from a magnetic drum 10.

Abstract: 1,053,038. Hydraulic brake; speed control. MAYBACH MOTORENBAU G.m.b.H. July 2, 1965 [July 4, 1964], No. 28078/65. Headings F2E and F2F. A method of braking a rail vehicle by an hydrodynamic brake incorporating a toroid chamber formed by a vaned stator and rotor and kept filled by a centrifugal filling pump, comprises controlling the rate of liquid flow in the chamber circuit by removal of liquid from the circuit at the surface thereof. The brake comprises rotating blades 13 carried on a shaft 17 coupled to the propulsive unit of the vehicle and fixed blades 15, 16. The chamber is filled through pipe 20 from centrifugal pump 86 and fluid taken therefrom at 22 to return through valve 50 to the reservoir 85. Operation.-In the zero position of selector 68 the electromagnetic valve 87 of pump. 86 is closed, the piston 60 of valve 50 is raised by lever 70 and control pressure from the pump 89 enters chamber 58 to raise the control piston sleeve 55 to relap the land 61 and connect the ports 54, 56, allowing the fluid in the brake to drain off through port 22 to the reservoir. Initial movement of selector 68 opens valve 87 and the system fills with fluid, slight braking then occurs. Further selector movement lowers piston 60, port 63 opens and sleeve 55 falls to throttle the return flow through port 22 and lines 49, 91 to increase the braking. Beyond a medium position of the selector its member 69 abuts a lever 72 and raises a piston 34 of the valve 33 to allow control pressure from pump 89 to pass through conduits 90 and passages 45, 43 to enter chamber 27 to begin to withdraw the wall 21 to provide further braking increase until linkage 46, 47 recloses passage 43. When the selector is set at maximum the wall is fully withdrawn. To prevent the maximum brake torque being exceeded at any selector position a speed dependent pressure is supplied from the governor operated valve 74 to chambers 41 and 65 of valves 33 and 50 respectively to act in a manner corresponding to an opening of valve 50 and a movement of wall 21 into the toroidal chamber to decrease the braking.

Abstract: 1,054,802. Cutting by fusion. BRITISH OXYGEN CO. Ltd. March 7, 1963 [Dec. 8, 1961], No. 44041/61. Heading B3V. In the fusion cutting of a workpiece by a movable cutting head, the cutting is controlled by gauging means 1 which gauge the cutting depth of the surface to be cut immediately in front of the cutting point and control the cutting parameters accordingly. These cutting parameters may be the cutting speed, height of the cutting nozzle, oxygen flow rate and pressure, rate of pre-heating or, in electric arc cutting, the current used. A number of photo-electric cells 1 are mounted on a support 2 movable along rails 4 by a motor 5 towards a pattern 3 of the workpiece crosssection to be cut, or towards the workpiece itself. A callimated light source is situated below the cells and casts a shadow of the pattern on the cells 1 in accordance with the cutting depth of the workpiece surface adjacent the cutting head. These cells pass information along cable 6 to the cutting head. Alternatively the cells may be replaced by electric switches which contact the pattern. The pattern may be a template, a printed drawing or a short portion cut off from the actual workpiece. Control of the cutting speed may be effected by varying the field resistance of a shunt motor driving the cutting head; control of oxygen flow may be effected by solenoid actuated valves. The invention is of particular use in cutting hot rolled steel sections.
