Title: Central processing unit of a computing system
IPC: G06F15/78
Filed: 1972-08-29
Abstract: 1410081 Data processors TEXAS INSTRUMENTS Inc 29 Aug 1972 [31 Aug 1971 (7)] 40083/72 Heading G4A A processor comprises an instruction register 28, a parallel arithmetic- and logic-unit 32, and random access memory registers 40 which share a parallel bus 25 under control of circuitry 26, and interface circuitry 30 for transmission of data between the bus 25 and external circuits, all the units 26, 28, 30, 32, 40 and bus 25 being formed on a single integrated circuit chip. As described the processor operates on 8-bit words. The random access memory 40 comprises general purpose registers A-E, H, L, M and pairs of registers 42, 44 one pair of which acts as a program address register or counter and the remaining pairs are used as a push down address stack for nested sub-routines. Each pair of registers 42, 44 stores the low and high order parts of a 16-bit address in external memory, the 2 registers being individually addressable for reading and writing and addressable together for refreshing, FET charge storage technology being used. Each processor cycle consists of fetch and execute sub-cycles and is controlled by an 8-bit instruction. Move instructions include 3-bit destination and source (in memory 40) codes or a 111 source/destination code for external memory. Arithmetic instructions include a 3-bit operation-code (the destination is assumed to be the accumulator register A) specifying add or subtract with or without carry/borrow, NAND, EXOR, OR or Compare operations to be performed by a single logic circuit, Figs. 22-24 (not shown). I/O instructions transfer the contents of the instruction or accumulator register to external latches to control a peripheral device. Interrupts are handled by an interrupt program at locations spaced by 8K bytes in external memory. The instruction decoder may include a programmable logic unit in which a variable gating mask is provided. Operation of the processor is controlled by a state timer 22 having four states S1-S4 which may be sequenced in each fetch or execute subcycle, each state being subdivided into two phases. Timer 22 may also include a programmable logic unit to allow variation of the state times. A cycle timer 24 determines if an instruction requires 1, 2 or 3 cycles. A parity generator included in the arithmetic and logic section includes an array of FETs, Fig. 20 (not shown) in odd and even parity columns each of which receives complementary pairs of bit signals and is cross-linked to the other column. Two such processors may share a common member, one processor performing a fetch subcycle while the other performs an execute subcycle.

Title: Improvements in or relating to roofs for buildings
Inventor: ADLER FELIX
IPC: E04D3/06
Filed: 1960-11-22
Abstract: 935,852. Prestressed roofs. RICHARD COSTAIN (CONSTRUCTION) Ltd. Nov. 21, 1961 [Nov. 22, 1960], No. 40097/60. Class 20 (4). A prestressed roof is formed from V-shaped units, each comprising two pretensioned concrete plates 1 joined together along their long edges, supported side-by-side near their ends on beams 10a, and having their top edges 13 joined together. To join the plates 1 together to form the units, the projecting loops of the transverse mild steel reinforcement are interengaged while the plates are positioned on a cradle by means of turnbuckles, and mild steel bars, or prestressing cables for posttensioning the joint, are threaded through these loops before the valley joint is concreted. The longitudinal stressing wires are more numerous near the valley of the V, so that the plates when joined together tend to bow up at midspan, thus causing a natural drainage towards the ends of the units, where pitch fibre pipes 9 may be located in the valley. The steel girders 10a may be replaced by a concrete beam having its top edge shaped to the soffite of the units and insulated from them by a hollow rubber strip, and having a gutter on the outside to receive water from the roof. The top edges of the units may be joined together by inverted V-shaped glazing sections 15 or precast infill units 16. The top of the roof may be insulated by a layer of polystyrene covered with roofing felt, and the underside may be painted.

Title: Lubricants containing salts of oxygen-containing acids of phosphorus
IPC: C07F9/40
Filed: 1958-12-15
Abstract: Lubricating oil compositions, including greases, contain, as an antioxidant, 0.5-10% by weight of a phosphonate of the formula <FORM:0847346/III/1> wherein R11 is C1-C10 alkylene, M1 is an alkali or alkaline earth metal, M is an alkali or alkaline earth metal or C1-C10 alkyl, and R111 is C1-C10 alkyl.  In the case of lithium greases, the phosphonate also increases the dropping point of the composition. The lubricating oil may be a mineral or synthetic oil. Specified synthetic oils are esters of monobasic acids (e.g. C8 oxo alcohol ester of C8 oxo acid), esters of dibasic acids (e.g. di-2-ethyl-hexyl sebacate), esters of glycols (e.g. C13 oxo acid diester of tetraethylene glycol), complex esters, esters of phosphoric acid, halocarbon oils, sulphite esters, silicone oils, carbonate esters, polyglycols or mixtures of these.  The lubricating oil compositions may contain additional ingredients such as oxidation inhibitors (e.g. phenyl-alpha-naphthylamine), viscosity index improvers (e.g. polyisobutylene), corrosion inhibitors (e.g. sorbitan monooleate), dispersing agents (e.g. sodium petroleum sulphonates), pour depressants and dyes.  In the case of a lubricating grease, the thickener may be inorganic (e.g. graphite, carbon black or clay), polymeric (e.g. polyethylene) or a salt, soap, mixed salt or soap-salt thickener. Such salt and soap thickeners may be metal (e.g. alkali metal, alkaline earth metal, magnesium or aluminium) salts of monocarboxylic acids or sulphonic acids.  The monocarboxylic acids may be chosen from C12-C30 fatty acids, C7-C10 fatty acids and C1-C6 aliphatic monocarboxylic acids (e.g. formic, acetic, propionic or lactic acids).  The phosphonates and the salt and soap thickeners may be formed in situ in the lubricating oil by neutralization of the corresponding acid with metal bases.  In the examples, lubricating greases are prepared from (a) mineral oil, disodium ethyl carboxymethylphosphonate, sodium 12 - hydroxystearate, sodium petroleum sulphonate and phenyl-alpha-naphthylamine, (b) mineral oil, mono - ethyl carboxymethyl phosphonate, stearic acid and lithium hydroxide and (c) di(2-ethyl-hexyl) sebacate, calcium di-n-octyl carboxypentylphosphonate and calcium stearate.  The effect of omitting the phosphonate from grease (a) or replacing it by trisodium phosphate is described.

Title: Keyboard for calculating machines, teleprinters, terminals and the like
Inventor: BRESCIA RICCARDO
IPC: G06C7/02
Filed: 1970-08-24
Abstract: 1,270,892. Keyboards. ING. C. OLIVETTI & C. S.p.A. 24 Aug., 1970 [1 Sept., 1969], No. 40682/70. Heading G4H. A keyboard for giving a coded output corresponding to the key pressed comprises a pair of spaced ferromagnetic plates 16, 17, Fig. 2, having a magnetic field between them, the upper plate having holes 14 for ferromagnetic plugs 13 which, when the key 11 is pressed, move rapidly into contact with the lower plate, the space between the two plates containing a plurality of printed circuit boards bearing windings 19-22, Fig. 3, surrounding holes 24 for the plugs in different senses so that, according to which key is pressed, the corresponding plug passing through the holes 24 induces positive or negative pulses in each of the circuits, thereby providing a coded output. The magnetic field between plates 16 and 17 may be provided by permanent magnets or by electromagnets. The plug 13 is normally held in the raised position by spring catch 46, Fig. 5. When a key is pressed spring 43 is compressed as housing 38 slides over the head 41 of the plug. Eventually the housing releases the catch by bearing on the sloping part 47. The plug then flies downward causing a rapid flux change in the associated windings. When the key is released spring 37 returns the plug slowly to the initial position so that the induced signal is correspondingly small. The windings may be printed as shown in Fig. 3, half of each turn being on one side and half on the other side. The two half circuit are jointed at 30. The printed windings may be complete circles being adapted to be severed on one side or the other to give a half-circle passing in one sense or the other round the hole. The circuits may all be printed on the same flexible board, which is then folded to form a number of parallel circuits. Alternatively the circuits may be of wire, wound on a board with an upstanding collar surrounding each hole.

Filed: 1966-09-20
Abstract: 1,199,152. Web-feeding. FORDS (FINSBURY) Ltd. 20 Sept., 1967 [20 Sept., 1966], No. 41877/66. Heading B8R. [Also in Division F2] Apparatus for feeding strip material intermittently through a machine incorporates a replaceable mounting member carrying means for adjusting the feed for longitudinal registration in response to detecting devices for faulty registration. Fig. 1 illustrates a variable-throw crank mechanism which can be utilized to drive the feed rollers of a machine for forming bottle caps from metal foil bearing a repeating printed pattern, as disclosed in Specification 778,615. Continuously driven boss 3 causes member 2 to rotate; one end of this member is attached to crank rod 1 which causes intermittent drive of the strip-feed rollers (not shown), while the other end carries a follower roller 4 riding in a cam groove. The operative length of the cam and hence the throw of the crank is variable by moving two parts 5a, 5b, forming the groove, relative to each other; this is achieved by moving two-part shell 6a, 6b, carrying the grooves 5a, 5b, about pivot 8. Normally part 6a is fixed but can be manually adjusted by screw 24; part 6b is automatically moved with respect to part 6a in response to signals received from a photo-cell detecting mis-registration: the photo-cell supplies signals to armatures 12, 14 which move stops 13, 15 against shoulders of lug 17 carried on shell part 6b. Since this part is biased against the stops by springs 30, the operative cam length is thereby varied by the signals, screw 16 determining the range correction. The complete variable-throw crank mechanism can be removably attached to the drive shaft of any suitable machine.
