Title: Pulley blocks
IPC: B66D1/54
Filed: 1974-04-25
Abstract: 1458115 Equalizing tension in ropes ODES POLITEKHNICHE INST 25 April 1974 18061/74 Heading B8B A pulley block which is mounted on a jib crane comprises a pair of ropes 4, 5 attached to respective winch drums 11, 12, the ropes 4, 5 passing about respective pulleys 1 which carry a load-supporting hoisting member 2, and are attached at their ends to the crane structure 9, the pulley block further comprising means for equalizing the tensions in the ropes 4, 5, said means comprising a pair of pulleys 6 about which the ropes respectively pass, the pulleys 6 being mounted on a frame 7 movable in guides 8 fixed on the crane structure 9, buffer stops in the form of springs 10 being provided with a clearance # between the ends of the frame 7 and the ends of the guides 8. Under normal conditions a load is lifted or lowered by the drums 11, 12 which wind or unwind the ropes 4, 5, the tensions of the ropes 4, 5 being equalized by the translatory motion of the frame 7 and pulleys 6 within the clearances #. Should one of the ropes, e.g. rope 4, snap the pair of pulleys 1 and hoisting member 2 begin to fall, causing the frame 7 to move leftwards in Fig. 1 thereby contracting the relevant spring 10 which is compressed to thereby smoothly decelerate the movement of the frame 7 until the latter is stationary. The ropes 4, 5 also pass about a respective fixed pulley 13, 14 mounted on the crane structure 9. In the embodiment of Fig. 2 (not shown) the tension equalizing means comprises a pair of rollers (24) about which ropes (20, 21) are respectively entrained, the rollers (24) being rigidly interconnected so that their surfaces define a cylinder (25) which is threadedly mounted on a screw (22) which acts as a guide, buffer stops (26) which each consist of a fixed and movable plate (27, 28) with a spring (29) therebetween being provided towards the end of the screw (22) at a respective clearance (#) from the cylinder (25), and as the tensions of the ropes (20, 21) are being equalized the cylinder (25) moves along the screw (22) within the clearances (#). In this particular embodiment the pulley block is mounted on an overhead crane, but both the pulley blocks described may be used with hoisting devices other than cranes.

Abstract: 1470517 Timing ignition; ignition systems LUCAS ELECTRICAL LTD 18 April 1974 [18 April 1973] 18658/73 Heading F1B An ignition system for an internal combustion engine comprises a mass flow measuring device for producing an electrical signal representative of the mass flow of air in the induction manifold 10 of the engine and a control device for automatically adjusting the ignition timing of the engine in accordance with the electrical signal. The counter 30 receives pulses from the converter 18 for the duration of the intervals between pulses in the pulse train at the output terminal 25. These pulses emanate from the detector 23. At the start of each interval the gate 27 is opened to admit pulses to the counter 30 and the gate 28 is also opened to admit pulses from the terminal 26 to the converter 31. The count state of the counter 30 at the end of the interval will depend on the product of two parameters namely the frequency of the pulses admitted, which is dependent on the air mass flow-rate through the induction manifold 10 and the length of the interval which is dependent on the speed of the engine. This count state will be directly related to the total mass of air which has passed along the manifold 10 during the interval. During the interval the gate 29 is closed. At the commencement of a pulse at the terminal 25, which occurs when the piston of the engine is at its maximum advance position, the gates 27 and 28 close and the gate 29 is opened. At the same time the monostable circuit 34 is triggered so that the output of the memory 33 corresponding to the existing values of the outputs of the counter 30 and the converter 31 is read into the counter 32. It is arranged that the output pulse of the monostable circuit 34 is completed before a pulse from one of the holes 19b in the plate 19 is produced at the terminal 26. Thereafter 2 degree marker pulses are admitted to the counter 32 to reduce its count state to zero, when the counter is reset and the spark generator is triggered.

Abstract: 993,810. Measuring coating thickness using radiation. UNITED STATES STEEL CORPORATION. May 13, 1963 [June 6, 1962], No. 18906/63. Heading G1A. The thickness of a coating material on a base material having an atomic number at least three greater than the coating material is measured by directing a primary X-ray beam on to the coating at a potential sufficient to excite the coating but lower than the potential required to excite the base material and measuring the intensity of the resulting characteristic radiation emitted from the coating. In the arrangement shown X-rays from a tube 5 are received by an aluminium coating C on a ferrous base B and the resulting characteristic X-radiation from the coating is detected by a standard flow proportional counter 8 after passing through collimating tubes 10. The signal from the counter 8 is fed through a linear amplifier to a pulse height analyzer 16 which allows only the signals resulting from the characteristic radiation from aluminium to be counted by three high speed binary counters 18 and a six stage decode scaler and timer 20. The scaler and timer 20 are calibrated against known standards so that they provide an indication of the thickness of the aluminium coating. The apparatus is contained in a vacuum chamber 2 evacuated by a pump 4.
