Title: Skip for conveying concrete
IPC: E04G21/02
Filed: 1962-10-26
Abstract: 972,610. Skips for concrete. J. SCHMID. Oct. 26, 1962 [Oct. 27, 1961], No. 40648/62. Heading B8H.  A skip 1 is closed by two part-cylindrical shells 35, 36 carried by pairs of segments 33, 34 which are pivoted on shafts 45 disposed outside the skip, an operating lever 55 being provided for opening the skip through linkages 49, 50, 51. The skip has two outlets arranged side-by-side, each closed as described above and both controlled by the lever 55. A latch 52 engages slots in both members 51. When the skip is closed the point at which the link 50 is pivoted to the link 51 is on that side of a pivot 56 which is nearer the skip, thus providing an over-centre action to the closing linkages and the lever 55. The lever 55 has considerable mechanical advantage during the initial opening movements.

A two-wheeled trolley 1 pulled by a rope 15 along a fixed cable 4, such as the inclined guy rope of a television mast, and supporting by a connection 22 a load (not shown) such as a bosun's chair, is provided with brake shoes 5, 6 engaging the cable 4, the shoes being normally held open by the pull in rope 15. The fixed shoe 5 and movable shoe 6 are each fitted with a pair of cable-engaging rods, Fig. 3 (not shown), lying parallel to the cable 4 to provide four lines of contact. The shoe 6 is actuated by a cam 11 on a spring-loaded arm 12 pivoted to the trolley 1. Also pivoted to the trolley are levers 13, 19 attached respectively to the rope 15 and the load 22, the levers 19, 13, 12 being interconnected by links 20, 16. If the rope 15 breaks the brake 5-6 is initially applied by spring 17, and then, as drag increases, by the load 22 acting through the linkwork shown. The shoes 5, 6 may be changed to suit the size of the cable 4. The trolley may be removed by withdrawing pivot pins 14, 18.

[Also in Division H1] A holding magnet comprises a peripheral portion consisting of alternating layers of sheets of plastic material in which has been compounded powdered permanent magnet material of high coercive force, and sheets of flexible material of relatively high magnetic permeability, the sheets with the material of high coercive force being magnetized perpendicularly to their surfaces, and the polarity being reversed between one such sheet and the next such sheet separated from it by a sheet containing the material of high permeability, the edges of the whole assembly of sheets being flush with each other at at least one end of the peripheral portion. The plastic material may be rubber, synthetic rubber, polyethylene or polyvinyl chloride. The material of high coercive force may be barium ferrite. The sheet of high permeability may be formed of plastic material with which a powdered material of high permeability, e.g. soft iron, has been compounded, or may be a thin metallic sheet, e.g. of soft iron. The sheets may be stuck together by adhesive, or by bonding. Each magnetized sheet may have one surface wholly of one polarity, and the opposite surface wholly of the other, or the polarity of each sheet may be reversed alternately in bands or areas over the face of the sheet, provided that fairly closely corresponding reversal takes place in the alternate sheets. Magnets may be formed by winding a sheet material of four layers, two magnetized in opposite senses, the other two of high permeability interleaved therewith, around the inside or outside of a former of regular or irregular shape, and may then serve to hold the former in place on a ferromagnetic surface. Specifications 950,273 and 950,277 are referred to.

Abstract: 936,612. Signalling displacement and fluid flow electrically. CONSOLIDATED CONTROLS CORPORATION. Dec. 2, 1959 [Dec. 9, 1958], No. 40972/59. Class 40 (1). [Also in Group XXXV] In a system comprising a device 25, the motion of which it is desired to measure indicate or control, there is provided a differential transformer 10 the output of which is determined by the position of a movable core 20 of the transformer 10, the core 20 being moved in accordance with the motion of the device 25, further means being provided to stabilize the transformer output against fluctuations in the magnitude or frequency of the applied voltage at ambient temperature. The voltage difference V1-V2 of the secondary windings 15, 16 is a measure of the position of the core 20 and hence of the device 25 whilst the sum V1+V2 which will normally be constant is used to control the energization of the primary winding 11 of the transformer 10, the sum V1+V2 being compared with a reference voltage from a source 30 and any error being used to vary an impedance 12 in the circuit of the primary winding 11 whereby the sum V1+V2 is maintained at a constant value. The reference source 30 may comprise a number of Zener diodes and the impedance 12 and the error signal amplifier 13 may be a magnetic amplifier. The system may be arranged to be current responsive instead of voltage responsive and the primary winding energization may have an added control factor responsive to the difference of the secondary voltage or currents thereby the system is rendered non-linear, for example a square root at an inverse function may be obtained. Specification. 936,613 is referred to.

The grinding wheel 2 is mounted on a head 1 which is connected by a feed screw 15 to the in-feed table 14 and the in-feed movements of which are detected by a device 5. The output from the detecting device 5 and the output from a measuring device 4 having sensors 6 which measure the size of the workpiece are connected to a counting circuit 7 which produces a deviation signal from the output signals. The deviation signal is fed through an amplifier 8 to a comparator 9 which also receives signals from the measuring device 4 and a preset device 10. The output from the comparator passes to a control circuit 11 of a driving circuit 12 of the motor 13 of the in-feed table. From the position P0 to P1, the residual stock V0 increases to a value G. From position P1 to P2 the preset device 10 is set so that the residual stock is at a value G0 which is determined by the comparator 9 comparing the actual size of the workpiece as indicated by the output from the measuring device 4 with that from the preset device 10 and the deviation is indicated by the difference in the outputs from the measuring devices 4, 5. The control circuit 11 then controls the feed of the in-feed table 14 to maintain the value G0 constant.

Abstract: 951,556. Voltage stabilizers. PYE Ltd. Nov. 6,1962 [Nov. 24, 1961], No. 42131/61. Heading G3X. In a voltage stabilizing circuit, the unstabilized voltage is applied over a resistor R2 and the parallel combination of a resistor R3 and a Zener or avalanche diode D to the anode of a stabilizer tube V2, and the stabilized voltage is taken from the junction of resistor R2 and diode D. It is stated that the usual stabilizing circuit employing a gas discharge tube (Fig. 1, not shown) produces a "spike" in the output voltage, when the circuit is initially switched on, because of the difference between the striking voltage of the tube and its running voltage. By arranging for the stabilizing voltage of the diode D to be of the same order as this difference voltage,the "spike" is reduced or eliminated, and the stabilized voltage is higher than that produced by the tube alone (Fig. 3, not shown).
