Title: Improvements in or relating to hinges
IPC: A47B46/00
Filed: 1953-05-19
Abstract: 743,867. Hinges. CHEESEMAN, A. J. T. May 13, 1954 [May 19, 1953], No. 14048/63. Class 65 (2). A hinge comprises a leaf 2 adapted to be attached to a stationary member 5, a hinge pin 6, a leaf 1 adapted to carry a foldable flap 4 in a position such that the axis of the hinge pin lies substantially in the plane of the undersurface of the flap, and a latch device carried by leaf 1 and operable, when the flap is raised to the unfolded position, to enter into abutment with leaf 2 below the hinge pin so as to afford a rigid support for the flap, the latch device being manually releasable to enable the flap to return to its folded position. The leaves are of inverted channel form in crosssection, being provided for this purpose with side walls 7, and the side walls of leaf 2 are spaced farther apart than those of leaf 1 in order that the latter walls may pass within the former when the flap is lowered. The latch device comprises a lever 8 which is pivoted at 9 on leaf 1 and carries at its inner end a cross pin 11 urged by a spring 14 into recesses provided in raised portions 13 with which the inner ends of the side walls of leaf 2 are formed. The inner ends of the side walls of leaf 1 are formed with raised portions 16 adapted to prevent lateral displacement of the lever. Pin 11 is released by pressure on the outer end 10 of the lever to permit lowering of the flap, when pin 11 passes through an aperture 17 in leaf 1 and enters a recess 18 in member 5. In a modification the lever is in the form of a bell crank, the outer arm of which is operated, to release pin 11, by means of a push rod slidably mounted in leaf 1. The leaves may be cast from aluminium or aluminium alloy.

Title: Improvements in and relating to methods of preparing organosilicon chlorides
IPC: D06M13/517
Filed: 1944-07-25
Abstract: Organosilicon chlorides are prepared by a process which comprises the interaction of a hydrocarbon chloride and the silicon component of a contact mass comprising silicon and an oxide of copper.  The contact mass may be prepared either by the admixture of silicon with an oxide of copper, in which case the mixture is conveniently pressed into pellets, or it may be prepared by exposing a fused alloy of copper and silicon to an oxidizing atmosphere preferably at elevated temperture until it is converted from a hard brittle state to a friable state.  The hydrocarbon chlorides may be alkyl-, aryl-, aralkyl-, and alkarylchlorides.  In examples: (1) a 50 per cent copper-silicon alloy is heated to 155 DEG  C. for 20 hours, and then further oxidized after being broken up and packed into a glass tube, by the slow passage of air at an elevated temperature.  Chlorobenzene is then passed through at 420 DEG  C. to form phenyl silicon chlorides; (2) as in example (1) except that the copper-silicon alloy is pulverised before being air-treated; (3) methyl chloride is passed at 300 DEG  C. through a mixture prepared by mixing 10 parts cuprous oxide 90 parts of silicon to form methyl silicon chloride.  In place of the cuprous oxide, cupric oxide may be used.  A comparative experiment in which the unoxidized copper-silicon alloy is used is included.  It is stated that the compounds prepared according to the present invention may be used for treating water non-repellant bodies to make them water-repellant as described in Specification 572,740, [Group II].  Specifications 575,667, 575,668 and 575,669, [Group III], also are referred to.

Title: Record apparatus
IPC: H04N5/783
Filed: 1973-03-23
Abstract: 1376707 Television MATSUSHITA ELECTRIC INDUSTRIAL CO Ltd 23 March 1973 14254/73 Heading H4F Still or slow motion display of video signal fields longitudinally recorded on a magnetic tape is effected by means of a plurality, e.g. three, heads 30-32 on a drum 25 which is rotated in the opposite direction to the direction of tape movement. Each video signal field includes a vertical synchronizing signal, and the length of the tape scanned on one rotation of the drum is at least twice the recorded length of one field signal, the distance between the adjacent heads on the drum being preferably equal to or less than the recorded length of one field signal. The resulting played-back video signals from the three heads are gated in response to outputs from a ring counter 60 and combined 64 to form a video signal in which each field is repeated a plurality of times before the next field is similarly repeated a plurality of times, i.e. each field is effectively displayed as a still picture. If the tape is stopped then one field may be displayed for as long as required. The counter 60 is controlled by the vertical synchronizing signals, separated 66 from the displayed video signal, which are variably delayed 67, and also by a variably delayed 72 signal which denotes the angular position phase of the drum 25. This latter signal is derived when a permanent magnet 69 fixed to a disc on the shaft of drum 25 passes a stationary magnetic pickup 71. Sound may be recorded in a second track on the tape for which a stationary pickup head 33 is provided. The tape speed i.e. motor 24, may be controlled.

Title: Liquid polymers from alpha-olefins
IPC: C08F8/04
Filed: 1961-04-20
Abstract: 940,143. Liquid alpha - olefin polymers. ATLANTIC REFINING CO. April 20, 1961 [May 5, 1960], No. 14268/61. Heading C3P. Liquid hydrogenated polymers, suitable for use as lubricating oils, having a high oxidation inhibitor susceptability, a viscosity index of at least 135, or pour point not higher than about -25‹F., and a molecular weight of from about 400 to 700, are made by polymerizing an alphaolefin of the formula R-CH=CH 2  where R is a straight-chain alkyl radical containing from 6 to 10 carbon atoms in the presence of a catalyst consisting essentially of titanium tetrachloride and aluminium triisobutyl or an aluminium dialkyl hydride wherein the Ti to Al atomic ratio ranges from 2:1 to 7:1, recovering the liquid polymer, and hydrogenating it to produce a saturated oil. The polymerization is preferably effected in an inert hydrocarbon diluent. The alpha-olefin may be octene-1, nonene-1, decene-1, undecene-1, or dodecene-1. The aluminium hydride may be aluminium diethyl, dipropyl, or diisobutyl hydride. At the end of the polymerization reaction the catalyst is destroyed by conventional techniques e.g. water, methyl alcohol, or a dilute aqueous acid solution. The hydrogenation is generally effected at a pressure of 2,000 to 3,000 p.s.i. and at a temperature between 350 and 450‹F. using a Ni-on-kieselguhr or a platinum dioxide catalyst. The hydrocarbon diluent may be a pentane, hexane, heptane, octane, nonane, or decane, cyclohexane, methylcyclohexane, or dimethylcyclohexane, or benzene, toluene, or a xylene. Prior to hydrogenation unreacted monomer, and dimers are removed by distillation.

Title: Improvements in or relating to sheet feeding or conveying devices for use in paper folding or like sheet operating machines
IPC: B65H29/00
Filed: 1927-05-27
Abstract: 281,599. Canadian-American Machinery Co., Ltd., (Assignees of Hitchcock, R.). Dec. 2, 1926, [Convention date]. Sheet-registering devices; sheet carriers and forwarders.-Mechanism for forwarding paper sheets from one part of a machine to another part comprises a feed table, on to which the sheets are delivered side by side, provided with means for advancing the sheets whereby consecutive sheets are separated one from the other by imparting different speeds to them. In the arrangement shown in Figs. 1 and 2, the sheets leaving buckling folders 14 - - 20 are slit by discs 26 before passing on to an inclined-roller feed table 28, where they are fed at right-angles to their previous, movement against a guide-bracket 31 adjustably carried by a rod 30 situated between a pair of inclined rollers 29. According to the invention, angle pieces 34, 35 secured to the bracket 31 are provided with apertures 36, in selected ones of which balls 37 of steel, glass, or other suitable material can be placed so as to co-operate with the rollers 29 and feed the leading half of the sheet more quickly. If desired, balls of material such as rubber, cork, and wood of high frictional coefficient may be placed in the unoccupied apertures so that the friction between them and the apertures causes them to retard the following half of the sheet. The centre of each ball 37 is spaced a little behind the axis of its co-operating roller 29 so that there is a tendency to bend up the front edge of the sheet and prevent the corner from getting under the guides plate 33 on the bracket 31. If the cutting-discs 26 are not utilized, balls 37 of glass or steel are placed in all the holes 36 so as to increase the speed with which the sheet is fed away before the next sheet arrives on the table. In a modification, Figs. 7 and 8, the balls 37 are replaced by conical rollers 41 the action of which is adjusted by adjusting their pressure on the rolls 29. 'The rollers 41 project through openings in the horizontal portion 40 of a member 39 which is secured to the guide plate 33, the spindles 43 of the rollers being arranged parallel to the rollers 29 and journaled in brackets 44 slidably mounted on bolts 45 screwing into the member 39 and supported by springs 46, 46<1> arranged above and below each bracket. The arrangement of the balls 37 or rollers 41 also prevents rebounding of the sheets from the guide 33 and checks the tendency of long sheets to slew around when they reach the guide. The sheets leaving the table 28 pass through folders 47 at right-angles to the folders 14 - - 20 and are delivered on to a table 51 equipped similarly to the table 28 and which forwards them into a folder 55 or direct to a delivery belt 56.
