Abstract: 1,045,095. Thermal regenerators. H. BRANDT, and A. KRITZLER, [trading as APPARATEBAU ROTHEMœHLE BRANDT & KRITZLER]. Dec. 22, 1964 [Dec. 24, 1963], No. 52041/64. Heading F4K. In a thermal regenerator having chambers containing heat transfer material, condensation on the chamber walls at the cold end of the regenerator is prevented by providing all or part of these walls with internal heating means in the form of passages for a heating fluid. The chambers are normally formed by radial walls 27 which extend from a circular outer wall 26 to a circular inner wall. The invention may be incorporated in any of these walls, but as shown is applied to the radially extending walls 27, wherein the hot end 33 of the radial wall is unheated, and the cold end 35 is heated by steam passing through channels 41, 42 formed by welding a sheet 36 to the wall 35. Steam flows from one channel to the other through a small gap 44 between the sheet and the wall. In another embodiment, Fig. 8 (not shown), intended for use when the heating fluid is hot oil, the sheet forms a single serpentine channel. In another embodiment, Fig. 7 (not shown), the heated portion of the wall is slidingly connected to the unheated portion to permit of relative expansion.

Title: Electronic data processing system
IPC: H03K5/04
Filed: 1965-12-17
Abstract: 1,078,580. Digital computers; magnetic storage devices. NATIONAL CASH REGISTER CO. Dec. 17, 1965 [Jan. 18, 1965], No. 53612/65. Headings G4A and G4C. A digital electric computer comprising a central processing unit, a magnetic memory and a timing unit operates in a series of operating cycles in which the timing unit defines a first two-step memory cycle wherein a word is read from, and restored into, the memory and, if required, a second two-step memory cycle in which a storage location in the memory is cleared in the first step and a word is written therein in the second step, the logical operation of the central processing unit being performed, in each operating cycle, simultaneously with the second step of the first memory cycle. Thin-film magnetic memory.-(Figs. 5A, 5B, not shown). The memory used is essentially the same as the memory described in Specification 1,035,870, five words, each of 12 bits plus a parity bit being read out in parallel and any of the five words not being required being masked off and returned to their original storage positions. Timing circuit.-(Figs. 2A, 2B, 3, not shown). The timing pulses are essentially produced by tapped delay lines (44-49) an initial pulse (C) being produced by AND and OR gates under the appropriate conditions being applied to the commencement of the delay lines. A further tapped delay line (43) connected to an AND gate (25) to which is also connected the input to the delay line serves to prevent spurious noise pulses from starting the timing unit. An AND gate (41) partway through the delay lines (44-49) serves to terminate the cycle at the end of the first two-step cycle or allows the second two-step cycle to be produced in succession as received. Commands.-Commands may be single address or double address types comprising two or four words. Implicit addressing, where the second word is the operand, direct addressing where the second word is the address, or relative addressing, where the address is the contents of the second word plus a specified index register are possible. Operation-(Figs. 1A, 1B, 1C and 3, not shown). Each system cycle is initiated by the clock pulse C, which also clears the read and write registers for the main memory and an auxiliary " scratch-pad " memory. At the beginning an R-R cycle is a period in which the address of the storage location to be accessed is decoded and then two periods R, R for reading and restoration respectively. Any remaining periods in a cycle are used to allow the sense amplifiers of the memories to recover. A C-W cycle includes a decode period and two periods C, W for clearing and writing in the storage location whose address has been decoded. The logical equations governing the various operations in accordance with the settings of appropriate control transistor flip-flops and progamme counters are described.

Abstract: 1,163,096. Luminescent screens. TEXAS INSTRUMENTS Inc. 15 Dec., 1966 [3 Jan., 1966], No. 56134/66. Heading H1D. [Also in Division C4] A luminescent viewing screen includes a layer of phosphor particles of different electron energization levels (e.g. red, cyan and blue emitting particles 67, 69 and 71, respectively) and spaced, generally parallel electron energy absorbing stripes (e.g. stripes 79 and 75 of aluminium and insulating material, such as silicon dioxide, respectively. The screen may be included in a colour display T.V. system in which each phosphor 67, 69, 71 is energized only by electrons of energies greater than first, second and third preselected energy levels respectively. Electron energy absorbing stripes 75 and 79 may be placed over an aluminium layer 73. An incident fixed energy electron beam excites one, two and three phosphors in domains overlaid by two, one or no energy absorbing stripes respectively to produce red, warm and cool white images. In a two-colour display system (Figs. 1 and 2, not shown) operated from conventional red and green records, red and cyan emitting particles produce red and warm white images. An insulating layer (25) of anodized Al may be included. The stripes may be utilized to produce indexing signals or the beam position may be determined by fluctuations in emitted radiation (e.g. U.V. radiation or X-rays). The different energization thresholds may be obtained by providing one or more of the different types of phosphor particles with barrier layers (e.g. of silicon dioxide formed by the cracking of a tetraethoxysilane atmosphere containing suspended phosphor particles or by leaching out activator components near the particle surfaces), choosing phosphors of inherently different energization characteristics or one phosphor may act as a barrier for the other so that random mixes are not required.
