Title: Improvements in or relating to mercury vapour discharge vessels
IPC: H01J17/14
Filed: 1951-03-16
Abstract: 705,679. Metal-vapour discharge apparatus. SIEMENS-SHUCKERTWERKE A K T. - G E S. March 16, 1951 [March 16, 1950; Feb. 22, 1951; Feb. 22, 1951], No. 6419/51. Class 39(1) The cathode of a mercury-vapour discharge apparatus such as a converter or lamp is made of a solid amalgam, or one sufficiently pasty to resist sudden changes of level, containing a metal such as chromium, molybdenum, tungsten or uranium which does not take part in the discharge. Such a cathode is less susceptible to destructive effects in situations involving movement of the vessel, than a 'wholly liquid one. The amalgam is contained in or coated on a cup of iron which, if liable to be exposed to the discharge, is covered with a layer of more resistant material such as sheet molybdenum. The cathode spot has little tendency to travel (and may split up into a number of separate spots) but if it does it can be brought back to the centre by a high-current discharge produced by discharging a condenser through an exciting anode.

Title: Data processor interrupt system
IPC: G06F13/24
Filed: 1970-02-10
Abstract: 1299962 Identifying interrupts SANDERS ASSOCIATES Inc 10 Feb 1970 [10 Feb 1969] 6426/70 Heading G4A An apparatus for locating the origin of a computer interrupt signal comprises a first level 12 of groups 14-0 to 14-15 of storage elements 16-0 to 16-15 each of which is set by the occurrence of a corresponding interrupt signal, at least one further level 18 of a group of storage elements 30-0 to 30-15 each of which is set by the occurrence of a signal from the output of an "OR" gate 28-0 to 28-15 associated with a corresponding group of storage elements in the first level, and means responsive to the occurrence of a signal from the output of the "OR" gate 32 associated with the group of storage elements in the last level for identifying the addresses of corresponding bits in each level, thereby to identify the corresponding interrupt. As described the individual storage elements are flip-flops though they may be core stores. The occurrence of an interrupt signal online 22 causes counter 90 (Fig. 3) to be reset and the contents of the final group 20 to be stored in register 40. The content of the first bit position of register 40 is then examined by comparator 96. If this is a binary "1" the contents of counter 90 are entered in register 100, otherwise the contents of register 40 are shifted one place and counter 90 incremented. The shifting and counting will continue either until a "1" is detected or until 15 shifts have been made. When a "1" has been detected the relevant storage element in register 40 is reset by the circuit 118 and the count remaining in buffer 48. The contents of register 40 are then checked by the comparator 104 for any further "1's", a positive result indicating that more than one interrupt has been signalled. The contents of the storage group in the previous level indicated by the count in buffer 48 are then loaded into register 40 and the process is repeated. When a cycle has been repeated for each of the levels of storage elements the address of the interrupt signal will be held in register 100, and the appropriate subroutine is then activated. If a signal was generated by comparator 104 indicating that a further "1" was present in the register 40, the contents of the final storage group 20 are reloaded into register 40 register 100 is cleared and the procedure repeated. If no "1's", were present in the register 20 the comparator 92 emits a signal ESC-1 when shifts have been made in the register 40 without a signal indicating a "1" having been produced by the comparator 96; this situation could arise by an external request via amplifier 124 for a test run.

Title: Improvements in or relating to conveyors
IPC: A21C15/00
Filed: 1929-03-04
Abstract: 331,896. Greer, J. W. March 4, 1929. Jigging conveyers. - Relates to bunching or spacing mechanism associated with conveyers for confections. A transferring conveyer is positioned between two conveyers, the transferrer comprising g a reciprocable surface which transfers the goods one. row at a time and returns to its starting position between each transfer movement. The stroke of the transfer movement is gradually increased, and then rapidly reduced to its initial length, so that the goods are deposited on the receiving conveyer in spaced groups of rows. As shown, the goods spaced in rows 15 on the conveyer 11 are transferred by an intermediate web 10 to a conveyer 12 on which they are arranged in groups of rows, the spaces between which correspond to the gaps between the trays. The ends of the web 10 are secured to the ends of a double-armed lever 37, 38 which is rocked by a roller 45 engaging a cam groove 44. The web is thus reciprocated and with each reciprocation, a row 15 is taken from the conveyer 11 and deposited on the conveyer 12. As the web is reciprocated, the knife edge 32 is moved slowly from -the full line position in Fig. 3, to the dotted line position, so that each row is deposited further along the conveyer 12 than the preceding row. The knife edge then returns quickly to start another group thereby leaving a space between the groups. The web 10 is trained over a compensating pulley 34 carried on levers 69 pivoted at 70 and coupled by links 71 to arms 52 which are reciprocated by a cam 58 and actuate the knife edge 32. The knife edge 32 is engaged by forked ends of the arms 52 and slide in horizontal guides. Pinions 62 of various sizes may be used to vary the speed of the cam 58 and consequently the speed of the knife edge 32, which varies the number of rows in each group. The speed of the knife edge isslow compared with the speed of the web 10. The conveyer 11 may be the conveyer of a depositing machine, and the conveyer 12 which. is driven by a pulley 20 may feed the confections to a coating-conveyer from which they are discharged on to pans on the cooling conveyer.

Abstract: 530,777. Television. BLUE, A. H., and WOOD, R. D. March 6, 1939, No. 7233. [Class 40 (iii)] A system for colour television employs at the transmitter a beam of white light A dispersed by means of a prism D to obtain three colour bands E, F, G, which fall on photo-electric cells H, I, J, so that the outputs of these cells vary in accordance with the colour of a particular element of the subject. The outputs of the cells are transmitted to the receiver where they are applied to individual pairs of parallel plates N, O, P so as to produce corresponding charges thereon. These charged plates are said to deviate three colour bands Q, R, S, received from a source of white light T through a dispersing prism V and a polarizing crystal X. According to the amount of deviation of any particular beam more or less of that colour is allowed to pass through a corresponding aperture W so that a beam reconstituted at a point Y will have the colour of the subject transmitted. The means for scanning at the transmitter and the optical system described above are enclosed in a single container, Fig. 2 (not shown). In the receiver the white light source, optical system for producing colour, focusing means and scanning means comprising electrically charged plates similar to those used for deviating the colour bands are enclosed in a glass container the end face of which is used as a screen.
