Abstract: 874,373. Valve pulse generating circuits. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Nov. 4, 1959 [Nov. 10, 1958], No. 36047/58. Class 40(6) In a pulse generating circuit of the kind in which a pulse forming network is charged relatively slowly and then rapidly discharged through a load such as R1, an auxiliary discharge circuit, such as V, R2, is provided to discharge part of the energy prior to the generation of a pulse, the time interval between the initiation of the auxiliary discharge and the main pulsegenerating discharge being controlled. As shown, the pulse forming network PFN is charged from waveform 3 at the secondary of transformer T. The charge is retained by diode D as shown in waveform 4. A negative going sawtooth waveform, synchronized with the input waveform is fed to a comparator circuit 2 of the type described in Specification 789,608. When the sawtooth voltage reaches the value at the junction of the potential divider R3, R4, a pulse is generated, firing the gas tube V, and partially discharging the pulse forming network through resistor R2 to provide waveform 5. The hydrogen thyratron S is fired at time t s  discharging the network through the load R1. The amplitude of the pulse applied to the load R1 is controlled by adjusting the value of resistors R2, R3 or R4 or by adjusting the phase of the sawtooth voltage.

Abstract: 1,118,660. Photoelectrically controlled icing apparatus. SUCREST CORP. 11 Aug., 1966, No. 36086/66. Heading A2A. In apparatus, Figs. 1 and 2, for applying liquid icing to bakery and confectionery products 62, such as pastries in containers, carried on a light-transparent conveyer 59, the products pass between a lighted electric lamp 23 extending above and across said conveyer, and a plurality of photoelectric cells 17, which are disposed, beneath and across the conveyer, in a housing 27 mounted on an arm 26, turnable about the axis of the lamp. Preferably, the lamp has a reflector 24 provided with a turnable shutter 25, and the housing 27 is provided with a turnable shutter 31. By adjustably turning these shutters, the width of the beam of light, which is directed towards the photoelectric cells, may be varied. A light-transparent window is preferably secured to the upper, lightreceiving end of the housing 27. As the products 62 pass between the lamp 23 and the photoelectric cells, they pass under an icing dispenser 11, Fig. 1, having a plurality of dispensing ports (100), Fig. 3 (not shown), arranged across the conveyer. Each port can be closed by the point 67 of a needle 66, Fig. 6, having, at its other, upper end, a collar 101, Fig. 1, which is urged, by a spring 73, against a collar 74 at the lower end of a push rod 102. The upper end of each rod 102 is received in a solenoid 49, which is connected, through a cable 64, a control cabinet 29 incorporating a relay, and a cable 30 to the associated photoelectric cell, so that, when light from the lamp 23 is impinging on said cell, the solenoid 49 is energized and moves the needle 66 downwardly, against the action of the spring 73, into a position in which it closes the port. When, however, a product intercepts the light from the lamp, the solenoid 49 is not energized, and the spring 73 moves the needle upwardly, so that the port is opened, and icing liquid, under pressure in the dispenser 11, is dispensed on to the intercepting product.

Title: Improvements in or relating to internal shoe drum brakes
Inventor: OSBORNE DUNCAN WILLIAM
IPC: F16D51/48
Filed: 1962-09-24
Abstract: 984,299. Brakes. AUTOMOTIVE PRODUCTS CO. Ltd. Sept. 13, 1963 [Sept. 24, 1962], No. 36284/62. Heading F2E. An internally expanding drum brake has its brake shoes arranged to give leading shoe action in both forward and reverse movement. One shoe 15 is pivoted by a link 19 to a carrier 16 one end of which abuts the actuating tappet 18 of a wheel cylinder 11, one end of the other shoe 13 abutting the stationary part of the cylinder. The other end of the carrier abuts the head of a screw 32 engaging a sleeve 31 slidable within a pair of sleeves 28, 29 disposed within a housing 12 and abutting an internal collar 23 therein. The other end of the shoe 15 engages a bar 34 spanning the end of sleeve 29 and passing across a slot in the head of screw 32. The other end of shoe 13 abuts a screw 25 in a sleeve 24 disposed in the end of the housing 12 and abutting the sleeve 31. A pressed metal strut 39 is arranged between the ends of shoes 13, 15 adjacent the wheel cylinder. Operation.-When the brake is applied with the drum moving in the direction of arrow 47 carrier 16 pivots about 32 to apply shoe 15 against the drum, the shoe pivoting about 34 and fixed housing 12 to act as a leading shoe. The carrier 16 tends to move circumferentially and applies a thrust to screw 32 and sleeve 31 which transmits this thrust through sleeve 24 and screw 26 to one end of shoe 13 which, pivoting at the other end on the cylinder 11, acts also as a leading shoe. When the drum is rotating in the other direction brake actuation causes shoe 15 to move out as before but then move circumferentially towards the wheel cylinder, actuating shoe 13 through the strut 39 to cause the latter to pivot as a leading shoe about its then forward end on screw 26. The shoes thus act as a two-shoe self-servo combination. Manual adjustment.-The sleeves 24, 28 are rotatable to cause screws 25, 32 to move longitudinally to adjust the shoe clearances. Alternative operation.-For parking, the carrier may be actuated by a bell crank lever 43. The wheel cylinder 11 may be actuated by liquid pressure or air or may be replaced by a cam or equivalent mechanical means operated by hydraulic or pneumatic means.
