IPC: G21C3/348
Abstract: 1,095,545. Fuel elements. UNITED KING- DOM ATOMIC ENERGY AUTHORITY. Aug. 16, 1965 [Sept. 2, 1964], No. 35923/64. Heading G6C. A transverse bracing grid for a cluster-type fuel element comprises undulating strip material attached to a bounding rim, the strip material being of two superimposed spaced layers and arranged so that loops of one layer co-operate with loops of the other layer to define a plurality of cells, each cell for containing a fuel rod. In the embodiment shown in Fig. 2, a fuel element comprises thirty-six fuel rods 1 arranged on four concentric pitch circles and includes a central tube. Each rod 1 has three parallel wires 16 helically wrapped over the length of the rod or disposed parallel with its longitudinal axis. Transverse bracing grids which are disposed at intervals intermediate the ends of the fuel element each comprise a rim 5 and a central ferrule 6 of thin stainless steel strip, the ferrule 6 being welded to the central tube of the fuel element. The annulus between the rim 5 and the ferrule 6 contains two superimposed spaced layers of thin stainless steel undulating strip. Each layer comprises three continuous strips, each strip being lap jointed as at 9 and arranged so that the layers co-operate to define four concentric annuli 10, 11, 12, 13 of cells for the fuel rods 1. In each layer 7, 8 contiguous loops of adjoining strips are joined by welding as at 14 and the strips defining the annuli 10, 11 of cells of each layer 7, 8 are interconnected by further strips 15. The strips defining the outer and inner annuli 10, 13 of cells of each layer 7, 8 are welded to the rim 5 and the ferrule 6 respectively. In an alternative construction, the strips are formed with concyclic projections 17 projecting radially inwardly of the cells to bear on the surfaces of the fuel rods 1.

Abstract: 1,159,578. Error detection; gated counters. WESTERN ELECTRIC CO. Inc. 9 Nov., 1966 [10 Feb., 1966], No. 50252/66. Headings G4A and G4H. A counter counting in a first code in which the parity of the count changes in an irregular pattern as successive pulses are counted, is checked by converting the count to a second code in which the parity changes in a regular pattern and then comparing the parity of the numbers of the second code to at least a portion of the counter input. Pulses at an input 20 are counted to form a pure-binary number in a register 14 utilizing inverters (shown as triangles) and NOR (called OR-NOT) gates, cross-coupled pairs of NORs being used for storage. The count is converted to Gray code in code converter 19 also using NORs for logic and storage. The combined parity of the stages of code converter 19 and the highest order stage of register 14 is obtained by a parity tree 70, utilizing NORs and ANDs, and compared with the input signal from 20 (delayed at 83 to compensate for delays in units 14, 19, 70) in AND 84 and NORs 85, 86 which thus produce an error indication if any input pulse does not correspond to a pulse from the parity tree 70 or any gap between input pulses does not correspond to a gap between pulses from the parity tree 70. As shown, the input 20 feeds the code converter 19 as well as the register 14 and there is feedback from the converter 19 to the register 14. The stages of the converter 19 change states in response to both the input pulses at 20 and the gaps between them, whereas the register 14 changes states in response to the gaps only. As a modification, the input of the delay 83 may be connected to the output, not input, of inverter 21, and the NORs 85, 86 eliminated. Additionally, a gate (enabled only part of the time) could be inserted at the input to delay 83.

Abstract: 1,230,642. Light-sensitive silver halide compositions containing tetra-azaindenes. MINNESOTA MINING & MFG. CO. Jan. 7, 1969 [Jan. 8, 1968], No.1146/68. Heading G2C. The invention comprises a light-sensitive composition comprising a silver salt of atetra-azaindene of the formula: - in which R is hydrogen, alkyl, aralkyl or alkylthio, R<SP>1</SP> and R<SP>2</SP>, which may be the same or different, represent hydrogen, an alkyl or substituted alkyl group containing up to 4 carbon atoms, or R<SP>1</SP> and R<SP>2</SP> together with the nitrogen atom form a ring which may contain other heteroatoms besides the nitrogen atom, and Y represents hydrogen, alkyl, alkylthio, aryl or amino, together with an intimately associated portion of a silver halide and  a method of making an image reproduction element comprising a layer of the above-defined lightsensitive composition in which an aqueous solution of the tetra-azaindene, preferably having a pH of from 6À0 to 8À5, is treated with a soluble silver salt (e.g. silver nitrate) to form the silver salt of the tetra-azaindene and, before or after coating the resulting mixture on to the substrate, the mixture is contacted with a water-soluble halide whereby some silver halide is produced in the mixture. The substrate may contain some watersoluble halide and when said mixture is coated thereon, some of the soluble halide is leached therefrom and forms silver halide in the mixture. The silver halide is preferably present in an amount of from 0À1 to 50% by weight. The composition preferably contains a water-soluble binder e.g. gelatine or polyvinyl acetate/alcohol copolymer. The compositions are sensitive only to ultraviolet and blue light but their sensitivity can be extended to longer wavelengths by the addition of spectral sensitizers e.g. cyanine and merocyanine dyes. The light-sensitive element may have a super-coating of hydroquinone whereby, after imagewise exposure, an image can be developed either by heating or treatment with an alkaline solution. It appears that the excess of the tetra-azaindene acts as a stabilizer and antifoggant for the system. It is believed that the compositions are light-sensitive because of the incorporation of the silver halide and that the silver salts of the tetra-azaindenes are only very slightly, if at all, light-sensitive. On the other hand, once a latent image has been formed in the silver halide, it is believed that subsequent development utilizes the silver provided by the silver salt of the tetra-azaindene.

Abstract: 1,233,951. Data processing. INTERNATIONAL BUSINESS MACHINES CORP. 23 Aug., 1968 [27 Sept., 1967], No. 40417/68. Heading G4A. A data processing system comprises a main store for data and control words, an auxiliary store capable of performing a plurality of read/ write cycles during each read/write cycle of the main store, means to read out a multi-byte word from the main store and selective transfer means to transfer a multi-byte data word to the auxiliary store or a multi-byte control word to a control register, means to send a data word in the auxiliary store a byte at a time to an arithmetic logic unit for processing and to store the result in the auxiliary store, a control word being read from the main store to a control register and decoded to provide a sequence of control signals to control the processing of one byte from at least one data word by the arithmetic logic unit. The main store also stores instruction words. The auxiliary ("active") store has predetermined locations for the instruction counter, main store addresses of two operands, working areas and general purpose registers. Each operand address from the auxiliary store has a word portion for addressing the main store to obtain a (4-byte) operand word which is then stored in one of the auxiliary store working areas. The operand address also has a 2-bit byte portion indicating the first byte of the operand word which actually belongs to this operand. The byte portion is stored in a marker register in a sub-unit accessing and modifier circuit. The marker register has space for two such byte portions (for two operands respectively), and a 4-bit mask which is set as successive bytes are processed to indicate which bytes of the appropriate one of the main store operand words are to be replaced by the processing result when this is transferred into the main store from the auxiliary store. As successive bytes are processed the byte address portions in the marker register are incremented or decremented (according as bytes are taken going rightwards or leftwards along the operand words) by two 2-bit parallel adders which also function as decoders and serve to select, from operand words read from the auxiliary store, successive bytes to be fed to the arithmetic logic unit, and serve to update the mask in the marker register. Control words, besides feeding the control register, the contents of which are decoded to control system operation, also go direct to further decoding circuits, some of which control the main store to read or write a byte, half-word or word, selectively, the information read or written going to or coming from the auxiliary store. Control words also control addressing of the auxiliary store.

Abstract: 1,252,796. Piston return devices in stapling machines &c. SIGNODE CORP. 27 May, 1969 [27 May, 1968], No. 26680/69. Heading B4C. In a pneumatically operated device e.g. a stapling machine, a piston 36, Fig. 1, is driven by compressed air, controlled by a spool valve 90, in a cylinder 34 connected by holes 63 with an annular chamber 62. This chamber is for containing compressed air to return the piston 36 when the space 82 above the piston is relieved by the valve 90. The spool valve 90, in the position shown in Fig. 1, closes the space 82 above the piston 36 from the compressed air in air inlet chamber 84, and connects the space 82 with the atmosphere through an outlet 112. The valve 90 is lowered by the differential action of the compressed air in the inlet chamber 84 whilst a ball valve 120 is held in its uppermost position by a trigger 110 to cut off the space 94 below the spool valve 90 from the compressed air. In its lower position the valve 90 closes the outlet 112 and allows compressed air to enter the space 82 causing the piston 36 and driver 38 to perform its drive stroke. Different embodiments comprise different constructions allowing the compressed air to enter the annular chamber 62. The piston 36 and annular chamber 62 have 0-rings 60, 70 mounted in grooves, either of which 0-rings may have notches cut out of its lower face, Fig. 6 (not shown), or may have projections on its lower face, Fig. 8 (not shown). These constructions allow compressed air to leak past the O- ring when it is resting on the lower edge of its grooves. In an embodiment in which the piston 0-ring has the notched construction, compressed air can leak past the piston 36 and into the annular chamber 62 during the downward stroke and whilst it is stationary at the bottom of the cylinder 34. However when the piston is returned by the compressed air below the piston and in the annular chamber 62 the O-ring 70 then abuts the upper edge of its groove. Channels 130, 132 are provided to remove any residual compressed air below the piston when at the upper end of the cylinder 34. In an embodiment in which the annular chamber O-ring has the notched construction, Fig. 11, compressed air passes through passages 332, 333, and around the O-ring 270 during the downward stroke of the piston and whilst it is stationary at the bottom of the cylinder. However the annular chamber is sealed when the pressure above the piston and 0-ring 270 is relieved. In a further embodiment, a passage (523), Fig. 12 (not shown), connects the annular chamber 62 with the inlet chamber 84 when the valve 90 is in its lower position, and is shut off from the compressed air when the valve 90 is in its upper position.
