Abstract: 1288918 Reforming naphtha ESSO RESEARCH & ENG CO 23 Dec 1969 [15 Jan 1969] 62645/69 Heading C5E An improved hydroforming process comprises the steps of preheating a feed of a hydrocarbon fraction boiling within the range of 50 to 450 F. to a temperature between 750 and 1150 F.; passing said preheated hydrocarbon fraction downwardly through a first fixed bed of catalyst, said first fixed bed of catalyst comprising a hydroforming catalyst in its upper portion and a selective hydrocracking catalyst comprising hydrogen erionite in its lower portion; preheating at least a portion of the effluent from the first fixed bed to a temperature between 750 and 1150 F.; passing at least a portion of said preheated effluent from said first fixed bed over at least one additional fixed bed of hydroforming catalyst; and recovering a product having an improved octane rating, as compared to the feed, from the final stage. The hydroforming catalyst may be an oxide or sulphide of a Group IV, V, VI, VII or VIII metal on alumina gel, alumina, zinc-alumina spinel, chromia-alumina or silicaalumina. Molybdena-alumina and platinumalumina are preferred. The hydrogenation catalyst combined with the erionite may be a metal or oxide of Groups Vb, VIb, VIIb or VIII of the Periodic Table (U.S. version), e.g. Co, Ni, W, Pt, or Pd.

Abstract: 1289750 Controlling strand handling machines; stop motions BENJAMIN BOOTH CO 2 Dec 1970 [2 Dec 1969] 57354/70 Headings DID and D1F An apparatus for controlling the operation of a strand handling machine comprises: a yoke 20 comprising a base 21 which base, together with two leg portions 22, 23 depending downwardly therefrom, defines a strand passage 24; and machine control means responsive to output from a strand sensing means associated with the strand passage 24. The strand may be any indeterminate length of textile material such as fibres, yarn, rope, tow, sliver, filament, and yarn bundles. The invention is applied to the stop motion system of a carding machine 10, Fig. 1, in which a web W of fibres from a peeler roll 12 is condensed to form a sliver S which after passing through calendar rolls 14, 15 passes through the yoke 20 under tension and then travels upwardly to a sliver wheel (30) of a coiler head. 16 mounted above a sliver storage can 17. Light, from a source within a control box B, is directed through a light conducting member 25 and across the passage 24 towards a photo-cell 26. The photo-cell 26 is normally obscured by the sliver S but is exposed to the light beam should the sliver S break, slacken to occupy a position such as S", or have a smaller than required cross-sectional size S'. The wheel (31), Fig. 3 (not shown), is designed to act as a back up stop motion and a production counter, and has, for this purpose, a magnet (32) attached to it for actuating a reed switch (34) once per revolution. A control circuit for use with the apparatus is also disclosed.

Abstract: 1323082 Adjustable seat backs AUTOMOTIVE PRODUCTS CO Ltd 16 June 1971 [22 June 1970] 30192/70 Index F2S 31 [ Also in Division E2] An adjustable hydraulic seat stay has a hollow  plunger 17 having an apertured end 23 in which slides a fixed tube 31 connecting at 37 to a control valve 47 operable through pin 49 from the seat, e.g. by another hydraulic link (19, 20, 20a) Fig. 1, (not shown), to communicate to passage 42 and so allow fluid to pass between space 29 in the plunger and space 43 is the cylinder 16. Pressure is applied to the fluid by compressed gas forced through valve 57 into space 28, to act on the fluid through a free piston 26 sliding in the hollow plunger. Radial bores 51 allow passage of fluid to equalize the pressure when the device is fully extended. A screw-adjusted sleeve 52, with ball detent 54, limits the degree of compression of the device. In Fig. 3 (not shown) this is done by a stepped stop.

Abstract: 1328204 Fluid pressure servocontrol systems AUTOMOTIVE PRODUCTS CO Ltd 13 Oct 1970 [15 Oct 1969] 50674/69 Heading G3P A multi-channel control system for aircraft wing flaps comprises, in each channel, a first floating lever 38 connected at 53 to one end of control spool 23 and a second floating lever 37 connected at 53 to a sleeve 56 on the other end of spool 23. Levers 37, of each channel connect via 42, 44 and respective spring boxes (46) to a first control linkage (47, 49), whilst levers 38 connect via 43, 45 and further spring boxes to a second control linkage (48, 51) coupled to the first linkage via spring box (52). During normal operation, each spool 23 connects the control liner 29, 31 of a corresponding servomotor 12 defined by fixed piston 15 and moving cylinder 13 to supply 32 and exhaust 36 which connect with source 10 and reservoir 11 via release valve 33 whose spool 69 is held as shown against bias 101 by pressure in chamber 74 connected to source 10 via 32, 89, passages 94, 95 in pilot spool 64 and 92, 75, 105. If a control spool 2B or one of the levers 37, 38 should seize, the relative movement of spool 23 and sleeve 56 causes ball 58 to raise pilot spool 64 thereby connecting line 92 to exhaust line 97 to depressurize chamber 74, allowing spring 101 to move release spool 69 leftwards to interconnect opposite sides of piston 15 via 84, 82, 78, 77, 83, 85. The supply pressure is effective in chamber 91 to maintain the pilot spool raised. Accumulator 86 is connected to the by-pass circuit of piston 15 to prevent cavitation such as might be caused by restrictor 84, 85. Snub valves 104 as disclosed in Specification 1327393 cushion servomotor movement at the ends of the working stroke. Micro-switch 103 provides an indication of channel failure. Relief valves 99 relieve excess control pressure. In a system employing a single-acting servomotor, the release valve simply allows free flow into and out of the servomotor upon channel failure. The common control linkage may alternatively comprise a cable or telemotor.

Abstract: 1332274 Thermosetting resin impregnated laminates SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ BV 19 April 1972 18108/72 Addition to 1266097 Heading B5N An article impregnated with thermosetting resin is produced by impregnating a sheet having an open-cell foam structure, e.g. a flexible polyurethane foam sheet, with a curable thermosetting resin, e.g. an epoxy resin, applying a layer of fibrous reinforcing material, e.g. of glass fibres, to a side of the impregnated foam sheet, compressing the foam sheet and fibrous reinforcing layer to the extent that resin is expelled from the sheet into the fibrous reinforcing layer to impregnate this layer with resin throughout its thickness and allowing the resin in the sheet and layer to cure whilst maintaining the compression, the resin being allowed to cure in such a manner that the resin in the fibrous reinforcing layer is at first in a more advanced state of cure than the resin in the foam sheet, the compression of the foam sheet being reduced during this phase of the cure, and then the resin in both the foam sheet and the reinforcing layer being allowed to cure completely. The curing of the compressed assembly may be effected in a heated mould, the fibrous reinforcing layer being positioned adjacent the mould surface. The compression during the first phase of the cure may be such that the combined thickness of the foam sheet and the fibrous reinforcing layer after decompression is from 1À2 to 100 times the combined thickness thereof directly before the compression is reduced for the first phase of the cure. The articles may be used as wall or floor elements in buildings, as crash padding for automobiles or as sound reducing panels or shrouds.
