Title: Disc brakes
Inventor: HODKINSON HAROLD
IPC: F16D65/56
Filed: 1964-11-19
Abstract: 1,127,606. Disc brakes. DUNLOP CO. Ltd. 9 Nov., 1965 [19 Nov., 1964], No. 47057/64. Heading F2E. In a disc-brake assembly, a caliper housing 3 is mounted on a non-rotatable member 5 (not shown) so as to be axially movable relative to a rotatable brake disc 2, one friction element 10 being fixed to one limb 6 of the caliper housing and a movable friction element 11 is associated with the other limb of the caliper and is adapted to be actuated when a brake-applying mechanism presses the movable friction element 11 towards the brake disc, the brake-applying mechanism comprising a thrust member 14 mounted in the limb 7 of the caliper housing, an hydraulically-operated piston and cylinder device 21 and a mechanically-operated actuating device in the form of a lever mechanism 36, 31, the thrust member 14 being adjustable in length such that means associated with the lever mechanism is provided to effect automatic adjustment of the length of the thrust member to take up clearances arising from wear of the friction elements. The thrust member 14 comprises an outer member 16 within which is threadedly mounted an inner member 18 provided at its outer periphery with ratchet teeth 20. These ratchet teeth are adapted to be engaged by a pawl mechanism 38 pivotally mounted on a portion of the lever mechanism 28 such that when the brake is applied, either by the hydraulic mechanism 21 or by the mechanical brake applying mechanism 36, 31, the lever 28 is tilted towards the disc about a pivot pin 29. If the brake clearance is such that movement of the lever required to apply the brake exceeds a predetermined value, the pawl member 38 will re-position itself behind a fresh tooth on the ratchet wheel 20 and, on release of the brake, will be drawn back by a spring 40 to rotate the inner portion 18 of the thrust member 14 so as to increase the effective length of the thrust member. Between the hydraulic mechanism 21 and the thrust member 14 there is provided a push-rod 25 formed with a flange 27 between its ends for engagement by the lever mechanism 28. Alternative embodiments are disclosed in the Specification wherein instead of the hydraulic mechanism being axially aligned with the thrust member the hydraulic mechanism engages one end of a lever mechanism having a fulcrum on the caliper intermediate the ends of the lever mechanism and a mechanical brake operating mechanism provided at the other end of the lever such that the lever is arranged to apply pressure to the thrust member at a point between the ends of the lever.

Title: Method of and Device for Measuring the Thickness of Electrically Conductive Sheet Material
Inventor: URMENYI LASZLO
IPC: G01B7/06
Filed: 1967-10-19
Abstract: 1,173,828. Eddy current thickness gauge. L. URMENYI. Aug.5, 1968 [Oct. 19, 1967], No.47668/67. Heading G1N. The invention relates to the temperature compensation of an eddy-current thickness gauge for moving sheet-metal by deriving a compensating signal from a similar detector head applied to a uniform thickness cylinder driven by contact with the sheet so as to acquire the same temperature. The compensation detector coils (3, 4) may be applied to the walls of the cylinder Fig. 1 (not shown) or to internal or external flanges, Figs. 3, 4, (not shown) and the sheet material may be guided to take a 90 degree wrap round the cylinder (1, Fig. 4, not shown). Circuitry In one arrangement Fig. 5, the primary coils 37, 3, of the thickness gauge and the compensating head are energized from an oscillator 15, and the output of the compensating circuit is connected in series opposition to the amplified output of the thickness detector head. The compensated signal is compared with a reference voltage in a differential amplifier 22. For calibration purposes using a sheet 8 of known thickness and temperature, switch 39 replaces the compensation signal by a bias from a stable D.C., supply 34. In an alternative arrangement Fig. 6 the temperature compensating section operates a servo null system which also drives a "gain" potentiometer 42 in the thickness gauge section (shown at the top of Fig. 6 and being generally similar to the corresponding port of Fig. 5 with a differential valve voltmeter 46, 47 at the output). In the compensating section the primary coil 3 is energized from an oscillator 52 and the output compared with a reference signal in a differential amplifier 60, 61 which drives a servo-amplifier 67, 68 controlling a servomotor 73 driving the nulling-potentiometer 66 and the gain potentiometer 42. Modifications: - the temperature compensating signal may be derived from other sensors responsive to the cylinder temperature e.g. thermocouple or resistance thermometer and may be applied to a "variable-mu" valve in the thickness gauge circuit.

Title: Data processing systems
IPC: G06F12/10
Filed: 1972-10-17
Abstract: 1397253 Digital data storage INTERNATIONAL BUSINESS MACHINES CORP 17 Oct 1972 [20 Jan 1972] 47775/72 Heading G4A A data processing system comprises a main memory 109 and one or more data processing units 101, each unit 101 having a buffer memory 102 (i.e. a fast access memory) which stores portions of data from the main store. A processor accesses data in memory 102 using logical and real addresses (Fig. 1, not shown). A real address is a fixed buffer memory address comprising the address of a partition plus an offset determining the position therewithin. A logical address has a partition address and an offset determined by logic operations performed by the processor. The buffer memory supplies copies of the most recently used data to processor 101, stores updated blocks, maintains records and communicates with other buffer memories using a broadcast system. The buffer memory includes a cache 200 divided into left and right segments forming 2-way set associative mapping with the main memory. The system address is compared with the contents of a fetch directory to locate a data segment. A broadcast store directory 230 is used to determine the cache status for all broadcast searches and an associative translation directory 220 translates logical addresses to real addresses after being enabled by a latch 204 set by the processor 101. When a logical address is received in register 202, latch 204 is set, bits 14-19 of the logical address are used to access the directory 220 and bits 18-26 are used to index directories 200, 210. Bits 8-13 are compared with the output of the translation directory 220 in comparator 218. If they are unequal, an access must be made to segment and page tables (in a known manner) in order to find the correct real address for the logical address. If they are unequal, further comparisons are made and a cache 200 segment is sent to the processor. If a real address is received the translation operation is omitted.

Abstract: 1415862 Price Î weight calculations KUBOTA TEKKO KK 18 Oct 1972 [22 Oct 1971] 48102/72 Headings G4D and G4A In a digital weighing scale the weight and unit price are stored and the price x quantity calculation is performed in a single circulating shift register 14. The 80 stage shift register holds 20 decodes of data in BCD code; the register is divided into a 44-stage, a 32-stage and a 4-stage register and an input charging circuit 15 together with an adding circuit 16 change the state of the input stage of the register according to output of the individual registers and/or incoming data. The scale employs a code plate with a photo-electric detector to generate two signals 90 degrees out of phase which issues pulses on two lines for each increment of weight the phase determining the direction in which the balance is swinging. These pulses are counted into selected positions in the shift register to form a weight; if this value becomes negative, e.g. if the scale pan is removed a signal is issued. The unit price is set in by switches in a unit 27. Under the control of timing circuits 25, 26 the weight value is periodically transferred into an accumulator portion of the register (UA). Thereafter a decade at a time the weight value is reduced one unit at a time the unit price being added into the accumulator (LA) each time until the weight value become zero when the value remaining in the accumulator represents the total price and is transferred to other positions in the register. The value of unit price weight and total price are periodically read from the register to a display 24.
