Title: Improvements in and relating to means for controlling hydraulically operated working cylinders
IPC: B22D17/32
Filed: 1938-10-29
Abstract: 520,788. Hydraulic press working valves. POLAK, J. Oct. 29, 1938, No. 31343. Convention date, Nov. 16, 1937. [Classes 69 (ii) and 135] A piston slide valve control for controlling two hydraulically operated working cylinders. the pistons of which move in a predetermined time sequence, the piston slide valve being actuated by a hydraulic auxiliary control arrangement, is characterised by the feature that the valve travels rapidly through the effective parts of its stroke and at a slower, adjustable rate through the other parts of its stroke. Fig. 1 shows the application to a die-casting machine, comprising a mould-closing piston G and a pressing piston C<SP>2</SP>. In the setting shown, these pistons are held in their inoperative positions shown by constantly-acting accumulator pressure. The control valve D is then actuated to admit pressure to space H thus closing the mould. The control valve E is then actuated to put the space N above the slide valve to exhaust through' line A'. The accumulator pressure, constantly acting on the lower face of the piston valve moves it upwards rapidly to a position in which the accumulator pressure passes through line V to the intensifier B<SP>1</SP>, B<SP>2</SP> to increase the pressure on the closed mould; the line A<SP>14</SP> from the pressing cylinder is simul- 'taneously cut off from exhaust. In its further movement the part R of the valve closes the outlet port Sand exhaust from the space N takes place only through passages W<SP>1</SP>, W<SP>2</SP> containing the adjustable throttle-valve X; the valve thus moves slowly until the port S is again uncovered, exhaust from space N then taking place through grooves A<SP>1</SP> and space A' in the valve and port S. In ifs final position, the valve admits pressure from the accumulator through A<SP>14</SP> to the pressing piston as well as through V to the intensifier. The slow movement of the valve between its two control positions is such that sufficient time elapses between bringing into action of the intensifier and bringing into action of the pressing cylinder for the full intensified pressure to be generated in the mould-closing cylinder. Finally, the control valve E is actuated to admit accumulator pressure through line A<SP>3</SP> to the space N, whereupon the piston valve is returned to its lowest position, and the parts return to their initial positions. In a modification, Fig. 5, grooves A<SP>15</SP> are provided in the lower head of the valve, whereby when liquid is admitted to the intensifier through passage V, a throttled quantity also passes through said grooves, space A" in the valve, chamber A<SP>2</SP>, port A<SP>7</SP> and line A<SP>14</SP> to the pressing cylinder so that the pressing piston begins to move; this lessens the impact of the pressing piston.

Abstract: 1283269 Sheet counters KOKUEI KIKAI SEISAKUSHO KK and GLORY KOGYO KK 29 June 1970 [30 June 1969 (4) 18 July 1969] 31352/70 Heading G4D A sheet counter of the rotary vacuum type does not become operative until the vacuum produced by a pump attains a working value. When a pack of sheets has been counted the count is compared with a preset value, correspondence allowing a motor to open the sheet holder. Lack of correspondence brings up an alarm. The counter circuit can be reset by a push-button or automatically through a delay circuit at the beginning of each count. The count is effected by detecting magnetic members on the rotor corresponding to the number of vacuum heads.

Abstract: 669,541. Control of motors. BRITISH THOMSON-HOUSTON CO.. Ltd.. and RAYDEN, R. G. Nov. 30, 1948. [Dec. 4, 1947] No. 32075/47. Class 38 (iii). [Also in Group IX] Apparatus for varying the speed of ring spinning frame spindles during the build-up of the cop, comprises a motor driving the spindles. an electronic device 2 adapted to control the motor in response to a control voltage, and means for supplying to the electronic device a control voltage having a basic component which is a function of the position of the ring rail 10, and an oscillatory component which corresponds to the oscillations of the ring rail, whereby cyclic variations in the linear speed of yarn being wound on to the bobbin are eliminated or reduced in amplitude. As the cop is being built the ring rail oscillates and also rises progressively so that the arm 5 of rheostat X copies this movement, the intercoupled arms 6, 7, of rheostats Y, Z, being moved intermittently since coupling 3 allows lost-motion between shafts 8 and 14. The alternating potentialdifference between the arms 5 and 6 provides the control component of input voltage for the device 2 affording the desired cyclic variation of spindle-speed, this potential-difference rising to a maximum value which then remains constant throughout the remainder of the cycle. Rheostat Z provides the control component for the basic speed, zones 26, 27, 28 relating respectively to the initial acceleration period, constant basic speed, and deceleration. Voltages corresponding to desired values of initial, maximum, and final basic speeds are obtained from potentiometer rheostats A, B, and C which are connected to a direct-voltage source independent of that from which the parallelconnected. rheostats X and Y are energized. Specification 549,077 is referred to.
