Patent GB-683540-A (GB)
Abstract: 683,540. Time switches. BURRELL, E. J., and BURRELL, C. Dec. 4, 1950 [Dec. 2, 1949], No. 31061/49. Class 38 (v) [Also in Groups XXIV and XXXVIII] A process timer for the control of a number of simultaneous and consecutive operations comprises a shaft 30 driven by a synchronous motor 51 over a clutch which is engaged and disengaged at the beginning and end of a cycle of operations, the shaft carrying a number of graduated rotary members 10, each of which has a cam 61 and is individually adjustable relative to the shaft, each cam co-operating with a pivoted switch-operating member 60. The timer is started by closing a switch 50 to energize a coil 46 to rotate a shaft 43 clockwise, as seen from the right, thereby moving a cam face 42 on an arm 41 away from a lever 39, which together with a pinion 32 is allowed to slide to the left under the action of a spring 38. This movement engages the pinion 32 with a pinion 31 on the shaft 30 and with a friction disc driven by a pinion 34, from the motor 51, thus starting the shaft 30. Switches 64 controlled by operating members 60 are then actuated after periods determined by the positions of the cams 61. The shaft 30 carries a finger 49 which after one revolution thereof engages a spring 58 to open switches 52, 48 in the circuits, respectively, of the motor 51 and the solenoid 46. De-energization of the latter allows a spring 44a to rotate the shaft 43 in a counter-clockwise direction to engage cam face 42 with lever 39 so as to disengage the clutch. At the same time, a shaft 67 carried by shaft 43 engages the tails 66 of members 60 which are restored to their initial, "closed", positions, and the shaft 30 and cams 61 are rotated back to their initial positions by a spring 68. A graduated cylinder 17 co-operates with a mark 19 to indicate the time taken to perform a full cycle of operations, and has a slot 23 which may be engaged by the end 22 of a lever 20 so as to prevent rotation of the shaft 30 during adjustment of the cams 61. The shaft 43 may alternatively be moved in either direction by pushing or pulling a button 45, and the plunger of the coil 46 may have a push button head, replacing button 45, or the latter may act on switch 50. The coil 46 may move shaft 43 in both directions, in which case the switch 52 is omitted and the motor runs continuously, the coil 46 being energized and de-energized at the required times to operate the clutch.

Title: Calling instructions in a data processing system
IPC: G06F9/42
Filed: 1978-10-25
Abstract: A digital data processing system uses variable length instructions grouped in routines and subroutines. One of the instructions in a routine is a subroutine calling instruction, Fig. 10A or 10B, which includes an operation code, FA or FB and two operand specifiers. One operand specifier represents an argument list address or argument count and thus enables determination of the arguments to be passed from the calling routine to the subroutine, and the other operand specifier specifies the initial address of the subroutine, which contains a subroutine mask designating those of a set of general registers which are to be used by the subroutine and the contents of which are therefore to be stored, at memory locations specified by a stack pointer register, for when return to the routine is made. The contents of argument pointer, frame pointer and program counter registers are always stored. <IMAGE>

Title: Pendulum densimeter
IPC: G01N9/16
Filed: 1979-01-18
Abstract: A densimeter for measuring the density of a fluid includes a disc body 12 rotatable about an axis 14. Two open cavities 40, 42 are provided in the body so that the centre of buoyancy of the body is displaced from the axis. The body 12 has a generally homogeneous density and includes a region 44 wherein the density is different from that of the disc. Because of the density anomaly the centre of gravity of the body 12 is displaced from both the centre of buoyancy and from the axis 14. When the densimeter is placed in a fluid, the disc will rotate about its axis. The density of the fluid is determined from the angular position of the disc upon reaching equilibrium. Another embodiment employing weighted arms mounted on a hub is disclosed. <IMAGE>

Filed: 1979-12-21
Abstract: In a receiver for a spread spectrum communication system the received message 2 is fed to a convolver 1 long enough to contain two message bits, each consisting of a number of sub-bits having a predetermined sequence, while reference bits 3, each having a number of sub bits in the reverse of the predetermined sequence, is fed into the other end of the convolver. When a reference bit travelling in one direction is aligned with a message bit travelling in the other a match occurs and an output pulse 4 is generated and fed via a gate 7, opened only when the reference bit 3 is fully within the convolver, to a shift register 8, which is only stepped, by clock 9 via gate 10, when the reference bit is fully within the convolver 1. Taps 12 are spaced along the shift register 8 to correspond to the spacing and order of the message bits, the threshold gate 15 responding when the message bits are correctly aligned along the register to provide an output 17. <IMAGE>
