Abstract: 1,146,562. Valves. INSTRON CORP. 17 Feb., 1967 [2 Nov., 1966], No. 7816/67. Heading F2V. Valve suitable for use in an error correcting servo loop, comprises co-operating stationary and movable ported members 32, 60 controlling the flow of air from an inlet 30 to one or the other of two outlets 24, 26. The members are of laminated construction, in which the ports extend through the whole thickness of a lamina so that they can be very accurately sized. The stationary member 32 consists of five laminations of 0.015 inch hardened and ground shim stock. Ports 50, 52 in the layers adjacent the central layer open at the top surface and communicate through the outer layers 40, 42 and through parallel body parts 13, 15, with the outlets 24, 26. The movable member is a flexible beam of three laminations. The port 54 in the centre layer communicates through body part 13 with inlet 30. The members are clamped between the body parts by screws 17, 19. An electric torque motor comprises polepieces 94, 96 located in the body by pins 102, a coil 98 surrounding the beam, and a magnet 92.

Title: Electronic digital computing machines
Inventor: JOHNSTON ANDREW ST
IPC: G06F15/00
Filed: 1953-03-24
Abstract: 789,208. Digital electric calculating and storage apparatus. NATIONAL RESEARCH DEVELOPMENT CORPORATION. March 23, 1954 [March 24, 1953], No. 8155/53. Class 106 (1). An electronic digital computing machine having a first plurality of sources of or destinations for data signals selectable under the control of a machine instruction is characterized in that one of such sources or destinations is a bus-bar associated with a further plurality of sources or destinations. The electronic computer described in Specifications 789,207 and 789,209, which uses instruction words containing two address locations, each specified by 10 digits, 7 of which specify a particular word location on a magnetic drum, the particular track being specified by the remaining 3 address digits, is modified in such a manner that the number of tracks is increased from 8 to 23 without increasing the number of digits specifying the address, the increase being achieved at the expense of one combination of the " transfer from accumulator (TFA) digits. When these digits are " 110 which combination was spare in the earlier machine, a gate 56 is opened, allowing the first 4 digits of the " word " specifying digits of an address to be set up on a supplementary track selecting staticizor STS, the outputs of which (r, #r, s, #s, t, #t, u and #u) cause one of 16 electromagnetic relays RC7-RC22 to be energized to connect an associated head DLH7- DLH22 to a bus-bar 50 which replaces the original head numbered 8. Thus when an address specifies " track 8 " the actual track engaged is one of 16 depending upon which of the 16 relays RC7-RC22 is energized. Once any one of the relays is energized it remains so until a further instruction requires a different relay to be energized, and the machine is so programmed that track 8 is not specified immediately after the particular track connected to bus-bar 50 is changed in order to give the relatively slow electromagnetic relays sufficient time to operate. By suitable programming it is thus possible, when the TFA digits are not otherwise being used, to change the supplementary track selected and to perform some other machine operation with only one instruction.

Title: Catalytic isomerisation process
IPC: C07C5/22
Filed: 1962-03-02
Abstract: A process for the isomerization of a hydrocarbon which is capable of undergoing double bond shift comprises contacting the hydrocarbon with a catalyst consisting of a first metal halide which per se is a Friedel-Crafts catalyst, e.g. AlCl3 or FeCl3, a second metal halide which may or may not be a Friedel-Crafts catalyst, e.g. alkali metal chlorides or bromides, both of which are supported and have different anions but the same or different cations.  Preferably the hydrocarbon is a feedstock containing less than 20 carbon atoms per molecule, e.g. 3 : 3-dimethylbutene-1 and 4-methylpentene-1.  Example 2 lists as products from the isomerization of 4-methylpentene-1, 2-methylpentene-2, 2-methylpentene-1, cis/trans-3-methylpentene-2, and cis/trans-4-methylpentene-2.ALSO:Isomerization catalysts consist of a first metal halide which is a Friedel-Crafts catalyst per se, and a second metal halide which may or may not be a Friedel-Crafts catalyst, both being carried on a support and having different cations but the same or different anions.  Examples are AlCl3 or FeCl3 and an alkali metal chloride or bromide on silica gel.  If desired a complex halide, e.g. KAlCl4, may be used and other supports mentioned are naturally occurring silicates, diatomaceous earths, e.g. Kieselguhr, corundum and silicon carbide.
