Title: Data processing system
IPC: H05K3/00
Filed: 1971-09-16
Abstract: 1312396 Programmed data processors INTERNATIONAL BUSINESS MACHINES CORP 16 Sept 1971 [26 Oct 1970] 43156/71 Heading G4A A data processing system is arranged to assist in the allocation of a plurality of interconnected blocks, such as the individual gates, registers &c. of a computer circuit, to a plurality of modules whose maximum area and number of input/output connections is fixed. It is stated that, because of the large number of possible combinations of blocks which would have to be considered, a unique solution to the problem would be impracticable for any reasonable number of blocks. It is therefore proposed to perform the allocation in two stages by first assembling the blocks into basic groups (called vertices) which may contain one or more blocks, these vertices being determined according to certain rules and imposed conditions which severely limit the number of possibilities and then allocating the vertices to the modules in such a way that the maxima of area, and connections are not exceeded. The generation of the vertices is performed by the portion 10 of the processor for which a flow diagram is given (Fig. 2, not shown). Basically this operates by first selecting a set of "initiate" vertices; these are selected according to fixed rules, e.g. all the input/output blocks may be designated as initiate vertices, and by a list of vertices fed in at input 20 by the user. The processor 10 then develops each vertex by adding any further blocks which are connected to the inputs of the initiate vertices but are not already included in any of them. This can obviously lead to redundancy since some blocks may be added to more than one vertex. This redundancy can be reduced or eliminated by appropriate control input at 16 but some may be inevitable in order to achieve any useful solution. The output of the portion 10 is then fed into the portion 12 of the processor for which a second flow diagram (Fig. 3, not shown) is given. Basically this operates by an initial seeding operation whereby one or more vertices is allocated to each module (this may be a purely random selection or are governed by input data at 26) followed by a pairing operation in which vertices are allocated to modules which best satisfy certain criteria derived from the need to come as close to the maxima as possible without exceeding them. A particular example (Figs. 4-7, not shown) is discussed in detail in the Spesification in which a small block diagram is arranged in two modules each having only four terminals. The modules may be large scale integrated circuits the system being used to determine a suitable arrangement of the gates &c. on them. The system is also stated to be useful for a number of other allocating problems such as for allocating a number of people, who must communicate, to a number of rooms; or a number of pieces of related informatior. to the columns or pages of a newspaper; or blocks of programme instructions to individual sections of a computer memory.

Abstract: 925,151. Testing yarns. ZELLWEGER Ltd. Dec. 29, 1959 [March 2, 1959], No. 44105/59. Class 120 (3). [Also in Group XXXVI] In an arrangement for selectively classifying and indexing specific types of yarn defects, a weight per unit of length measurement in the form of an electrical signal is obtained by passing the yarn 1, Fig. 10, through a measuring head 2, and fed to the parallel connected inputs of filters 4, 5, 6 in the paths of indicators 7, 8, 9. The indicators may be arranged to operate respective counters when the respective filter output voltages exceed predetermined values. Alternatively a diode threshold arrangement may be included in the filter circuit. Neps a, Fig. 1, slubs c and thickened portions b, for a particular speed of yarn feed, give rise to characterizing frequencies which the filters are designed to select. In order to compensate for the electrode dimension in the direction of yarn travel a running time discriminator including an oscillator D is included in the nep circuit so that a pulse inlet flank which is not followed in a predetermined time by an outlet flank is not recorded. An alternative arrangement is described in which there is a single filter output and measuring circuit, and the running speed is varied to detect the different type of defect.

Title: Improvements in the production of cycloalkanols and cycloalkanones and of borate esters of cycloalkanols
IPC: C07C29/52
Filed: 1962-11-26
Abstract: <FORM:1027005/C2/1> A process of producing a cycloalkanol and a borate ester thereof and cycloalkanone from the corresponding cycloalkane comprises heating the cycloalkane with molecular oxygen at an elevated temperature in the presence of a boron compound capable of esterifying the cycloalkanol formed and in the presence of a benzene-type compound, e.g. benzene, toluene, or xylene in an amount of from 0.01% to 5% by weight based on the cycloalkane and insufficient to prevent the oxidation, and hydrolysing the borate ester produced to the cyclo-alkanol. An initiator for the oxidation reaction may be introduced into the mixture such as di-tertiary-butyl peroxide, methylethylketone peroxide, tertiary-butyl hydroperoxide, acetaldehyde or cyclohexanone or a mixture of two or more may be used.  The cycloalkane may be produced by hydrogenating a benzene-type compound with hydrogen to produce a mixture of cycloalkane with a proportion of unreacted benzene-type compound in the range of 0.01 to 5% by weight based on the cycloalkane. As shown benzene and cyclohexane are introduced into the hydrogenation zone 1 through lines 4 and 5, respectively and a purge stream containing primarily cyclohexane and 0.56% of benzene is recycled to the hydrogenation zone through line 6 hydrogen being introduced into the reactor through line 7. The effluent from the hydrogenation zone consisting substantially of cyclohexane and 0.05% by weight of benzene passes through line 8, is combined with the cyclohexane recycle stream 9, and enters the oxidation reactor 2.  The recycle stream 9 and the reactor effluent from line 8 are proportioned so as to result in a cyclohexane feed to the oxidation reaction containing 0.5% by weight of benzene.  The oxidation is carried out in the presence of metaboric acid.  A stream containing 8% oxygen and 92% nitrogen is introduced into the oxidation reactor through line 10. An effluent is withdrawn from the oxidation reactor 2 through line 11 and passed to a cyclohexane recovery tower 3.  The unreacted cyclohexane, containing about 0.56% benzene, is removed through line 9 and recycled as previously indicated.  The reaction mixture consisting primarily of borate esters of cyclohexanol is removed through line 12, hydrolysed and cyclohexanol and cyclohexanone are recovered by the process described in Specifications 996,792 and 996,791.  Specific examples are given in which a mixture of cyclohexane, metaboric acid and benzene with or without an initiator is oxidized to give cyclohexanol and cyclohexanone and comparisons are shown of the effects of differing amounts of benzene present on the amount of the final products.

Abstract: 988,231. Stamping. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. Dec. 15, 1961 [Dec. 29, 1960], No. 44684/60. Heading B3Q. [Also in Division G6] In the manufacture of nuclear reactor fuel elements comprising fuel members contained within a cylindrical protective sheath, the sheath is subjected to radial compressive pressure, without axial compressive pressure acting from end to end on the sheath, to form the sheath into intimate contact with the fuel members. In the apparatus shown in Fig. 1, in which the sheath is subjected to localised radial compression, a fuel element 14 is positioned in gland nuts 4 screwed into the horizontal bore 3 of a cylinder block 1 which block also has a vertical bore 2. Each gland nut 4 retains a gland ring 6 in the bore 3, which gland rings are circumferentially grooved to accommodate 0 ring seals 7. The inner end faces 8 of the gland rings 6 are of conical form and mate with the conical end faces of an annular rubber forming ring 9 located beneath the vertical bore 2 which is partially filled with hydraulic fluid 18. Pressure is applied to the forming ring 9 by the insertion of a plunger 11 into the bore 2 by means of a compression machine having a bore 19 on which the cylinder block 1 rests and a ram 20 which is applied to the plunger 11. The fuel element 14 comprises fuel pellets 16 having V- section circumferential grooves 17 into which the sheath 15 is forced. An alternative apparatus (Fig. 3) which applies pressure over the entire length of the sheath comprises an external support tube 21 fitted with end plugs 23, 24 having externally lipped tubular extensions 26, 28 through which a fuel element 35 is disposed and over which a thick walled rubber tube 29 is held under slight tension. The bore 30 in the end plug 24 through which the fuel element 35 is inserted is closed by a plug 31 and the whole assembly immersed in hydraulic fluid under pressure, which fluid enters the support tube 21 through apertures 22. The fuel element sheath 36 is thus subjected to radial compression along its whole length, the application of axial compression being prevented by the end plugs 23, 24.

Title: Methods of testing a functional logic unit
IPC: G01R31/3185
Filed: 1973-09-25
Abstract: Propagation delay testing is performed on a generalized and modular logic system that is utilized as an arithmetic/logical unit in a digital computer. Each arithmetic/logical unit of a computer is formed of arrangements of combinational logic networks and storage circuitry. The storage circuitry has the capability for performing scan-in/scan-out operations independently of the system input/output and controls. Using this scan capability, the method of the invention provides for the state of the storage circuitry to be preconditioned and independent of its prior history. Selected propagation paths through the system circuitry are sensitized by test patterns from an automatic test generator. By altering selected inputs and cycling controls applied to the networks of combinational logic and their respective associated storage circuitry, propagation delay indications through the selected paths are obtained to determine the status of these path delays through the logic system.
