Title: Improvements in or relating to the manufacture of electric discharge devices
IPC: H01J5/24
Filed: 1954-10-29
Abstract: 777,140. Discharge apparatus. M-O. VALVE CO., Ltd., and WINDSOR, L. R. E. Oct. 28, 1955 [Oct. 29, 1954], No. 31355/54. Class 39(1). Radiation focused from a high temperature source is utilized to make a seal. The glass bulb 1 of a tube which is to be sealed to the base 3 has a coating 2 of absorptive material, such as graphite, on the part where the seal is to be made. Radiant energy from an arc 5 operating at a colour temperature of about 5000‹K is focused by a reflector 6 on to the coating 2 ; a sufficient temperature to effect sealing (about 850‹C.) is produced, the tube being rotated for uniform heating. Exhaust tubes may be sealed off similarly.

Title: Improvements in jacquard mechanism for looms for weaving
IPC: D03C3/02
Filed: 1946-10-23
Abstract: 623,095. Jacquards. LABBE, A. H. Oct. 23, 1946, No. 31445. Convention date, March 25. Class 142 (i) In order to equalise the load on the actuating rod 4 by compensating for different numbers of hooks lifted by the griffe 2, the weight to he lifted is measured by a balance beam and an appropriate number of springs are coupled to the rod 4 either to help to lift the griffe or (in the form shown) to increase the resistance to a maximum value. As the rod 4 rises, arms 16 mounted on it engage shoulders 55 on a rod 9 coupled to the griffe<SP>2</SP>. The load on the griffe is transmitted through Jinks 18 to a balance beam 21 which swings about a pivot 22 against the action of a spring 51. The movement of the beam positions a slide 37 so that recesses 41 in its edge come opposite shoulders on bars 38 ; as the actuating rod 4 continues to rise, the unrecessed parts of the slide 37 engage the shoulders on some of the bars 38, thereby adding the force of springs 49 to the load on the rod 4. The load for each shed is then the same as when the maximum number of hooks are lifted by the griffe. Oscillation of the balance beam after a 'selection of springs has been made is prevented by a pawl 25 engaging a rack 61. A piston and cylinder 7, 8 form a dashpot.. In the alternative arrangement, the springs 49 are attached to the tops of the bars 38 and are normally stretched, the bars being held down by latches. The balance beam releases the latches from a number of bars, so that their springs help to raise the griffe, so making the power required the same as when the minimum number of hooks are lifted.

Abstract: 1304736 Identifying a signal bearing lead SOC D'APPLICATIONS INDUSTRIELLES DE LA PHYSIQUE 1 July 1970 [1 July 1969] 31991/70 Heading G4H A circuit for identifying which of a number of inputs has provided a signal comprises a gate 12A-12N associated with each input, a trigger 13A-13N connected to each gate and a switching matrix 15, connected to all the triggers, which initially acts as an Or gate passing the first signal to occur via a delay 16 to a unit 17 which blocks the gates, and to a unit 19 which causes the matrix to perform a scan and identify an individual trigger storing a signal. The circuit may be used to identify the particular wire of a wire chamber nuclear detector device. Selected groups of gates are enabled by switches 14a-14n by means of which selected zones of the chamber may be studied. These may be replaced by switches in the matrix 15. The signal on each input is amplified at 11A- 11N and the first to appear sets the corresponding trigger 13A-13N if the corresponding gate is unblocked. The output from the trigger passes through the gating circuit 15 and appears at the output S, causing blocking of the gates and scanning of the triggers. As described there are 512 inputs grouped in eight groups of 64. Unit 19 consists of three 3-stage registers each connected to a decoder device giving an output on one of eight leads. The eight blocks are successively scanned until an output is found. Each block of 64 is divided into eight groups of eight. When the block containing the signal is found, the eight groups are scanned successively until the group containing the signal is found. The separate 8 leads of this group are then scanned until the marked lead is found. The address in the three registers is then read out. Scanning may then continue to identify other set triggers.
