Title: Improvements in and relating to safety devices for cranes and the like
IPC: B66C23/90
Filed: 1930-12-29
Abstract: 376,282. Weighing-apparatus fitted to cranes. NASH, A. F., Ardua, Kingston Hill, Surrey. Dec. 29, 1930, No. 39098. [Class 143.] A jib crane or other lifting apparatus of the type having a variable radius of lift is provided with a safety device comprising two independently moving indicator elements, one actuated by the load to be raised, and the other in accordance with the angle of the jib or otherwise in accordance with the radius of lift, the two combining to indicate an overload. In Fig. 8, the load is measured by attaching the end of the rope 4 to a lever 30 which operates a piston 33 in an oil filled cylinder 34, the pressure being indicated by a pointer 52 on a dial 53, Fig. 2 ; the effect of varying head in the pipe line 51 is preferably balanced by running a dummy line up the jib and using a differential indicator. In an alternative form, the pressure gauge is connected to a cylinder or compressible chamber actuated by the load on the jib head pulley, either through a sliding member or else by means of the eccentric mechanism described in Specification 333,523 ; measurement may also be effected by passing the rope round a jockey pulley on the jib head. In further modifications, the pull on the winding drum or the tension in the guy rope which passes to the jib head are measured. Fig. 13 shows a form in which the compression in the jib is communicated to a pointer 85 moving over a scale 86 through an eccentric mechanism of the type previously referred to and a spring-controlled rod 76 to which the pointer is coupled at 83. In modifications of this form, the compression in the jib is measured by hydraulic apparatus of either the cylinder or compression chamber type mounted at the base of the jib or else forming part of a member to which the jib is hinged. In a still further form, the bending moment on the vertical post of the crane is measured. In the form shown in Fig. 18, the indicating mechanism is contained in a casing 100 mounted on the jib. A force corresponding with the load is applied by any of the means described to the rod 101 which communicates with the spring-controlled rod 102 moving between the guide rollers 103 within the casing ; the movement of this rod controls the pointer 118 through the link 109, toothed sector 110, bevel wheel 112, and hollow arbor 113. As an alternative to indicating the load by hydraulic means, electrical means may be employed, comprising an aggregate of carbon granules the resistance of which varies with pressure. In addition to the visual indication, an audible signal may be given or the operation of the crane automatically stopped when the danger point is reached. Specifications 333,523, [Class 143, Weighing-apparatus], 344,525, 355,900, and 367,088, [all in Group XXX], are referred to.

Title: Circuit arrangement for periodically interrupting the operation of a plurality of loads connected in parallel
IPC: B60Q11/00
Filed: 1970-08-19
Abstract: 1325359 Switching circuits LICENTIA PATENT-VERWALTUNGS-GmbH 19 Aug 1970 [3 Sept 1969] 39985/70 Heading H3T [Also in Division G4] A circuit arrangement for periodically interrupting the operation of a plurality of loads L 1 , L 2  or L 3 , L 4  connected in parallel, includes the series connection of a capacitance C 2  and a control resistance RM, which on interruption of the loads during use of the circuit arrangement, is connected in series with the loads, so that at the control resistance RM there appears a voltage pulse of duration which is short in relation to the duration of the interval in operation and of a magnitude which is indicative of whether or not the loads are intact, the circuit arrangement further includes a switching unit T 5 , T 6 , T Y , T 3 , T 4  connected for receiving the pulses and means responsive to the state of the switching unit caused by a voltage pulse indicative of a load failure for changing the frequency of interruption of the loads. With the switch SL in the position shown, transistor T 1  is on and transistor T 2  is off. By connecting switch S L  to either lamp loads L 1 , L 2 , or L 3 , L 4  T 1  turns off and T 2  turns on to energize relay R which closes contacts S R  and lights the lamp selected. Then capacitor C 1  charges via R 10  until transistor T 1  again conducts and T 2  turns off to interrupt the current to the lamps. The dark phase is determined by the time constant (R 1 +R 7 ) C 1  after which T 1  turns off and T 2  conducts and the above is repeated. At the start of the interruption period transistors T 5 , T 6  turn on and a voltage pulse (UM 1 , Fig. 2, not shown) which occurs at the junction of C 2 , R M  triggers thyristor T Y  on. This turns transistor T 4  on and transistor T 3  off. If, however, a load lamp has failed the smaller voltage pulse (UM 2 ) on interruption of the current to the load, applied to thyristor T Y  is not sufficient to turn it on. Transistors T 4  and T 3  are off and on respectively, so that a resistor R 2  is connected to modify the time constant of the pulse generator T 1 , T 2  and increase the pulse repetition frequency. This makes the tell-tale lamp L K  go off and on twice as fast to indicate a lamp failure. Apart from the capacitors and lamps all the components of the circuit can be in the form of an integrated circuit. A bi-stable trigger stage may be used instead of thyristor T Y . All the lamps L 1 -L 4  of the vehicle blinker system may be connected in parallel for warning operation.

Abstract: 1,167,438. Electricity meters. SIEMENS A.G. Sept.5, 1967 [Sept. 6, 1966], No.40490/67. Heading G1Q. In a polyphase induction-motor-type electricity meter, the disturbing torques M1 to M3 produced by interaction of the current fluxes of adjacent driving systems is compensated for by an opposing torque M4 and/or M5 produced by one or more iron-less coils each of which is situated in the gap between a current pole of one driving system and the adjacent current pole of the next driving system. Each such coil is physically adjacent one of the two current poles defining the gap but electrically connected, in series opposition, to the main winding of the other pole. The figure shows the disposition of the voltage poles (plain circles) and current poles (circles containing the symbol + or -) of a three-phase meter with 120 degrees spacing between driving systems. The current coils of driving system II have two electrically associated compensating windings which provide fluxes ## jII  and -## II  which act on the rotor disc at points adjacent the nearer current poles of driving systems I and III respectively. These fluxes interact with the current fluxes # JI  and -# JIII  from the relevant poles to produce the compensating torques M4 and M5.
