IPC: E06B11/02
Filed: 1960-03-09
Abstract: 896,630. Gates. GUSH & DENT Ltd. March 6, 1961 [March 9, 1960], No. 8380/60. Class 45. [Also in Group XXV]. A gate 1 which can open by hinging about either side on gate posts 10, 10<SP>1</SP> comprises an auxiliary stile member 3, 3<SP>1</SP> at each side capable of angular movement relative to the gate about an axis 2, 2<SP>1</SP>, coupling components 13<SP>1</SP>, 14<SP>1</SP> on each auxiliary stile member engageable with corresponding components 11<SP>1</SP>, 12<SP>1</SP> on the gate posts, and operating means on the gate for displacing one or other of the auxiliary stile members and its coupling components to a disengaging position so that the gate may be opened by swinging it about the coupling components at the other side, simultaneous disengagement of both sets of coupling components being prevented. The components 11<SP>1</SP>, 12<SP>1</SP> on the posts each comprise a vertical hinge pin having horizontal arms which may be threaded to serve as fixing bolts, and the upper and lower components 13<SP>1</SP>, 14<SP>1</SP> on the auxiliary stile members, shown respectively in Figs. 2 and 3, are shaped so that on tilting an auxiliary stile member in a direction to move its upper end away from the gate the components move to the disengaging position. The lower hinge pins have shoulders which support the components 14<SP>1</SP> and take the weight of the gate. The operating means comprises a pair of tie rods 5, 5<SP>1</SP> which connect the respective auxiliary stile members to opposite sides of a triangular plate 6 pivoted on the gate at 7 and rigidly connected to a control arm 8. When the control arm is vertical both sets of coupling components are engaged, and movement of the arm in either direction causes both tie rods to move in the same direction, with the effect that one set of coupling components is released and simultaneously the gate is tilted about its pivotal connection 2, 2<SP>1</SP> with the other auxiliary stile member in a direction to raise the side of the gate which has been released, thus transferring the whole weight of the gate to the coupling components on the side which remains connected. The lower components 14<SP>1</SP> are chamfered at 18 to ensure that they clear the shoulders when the gate closes.

Title: Manufacture of artificial threads from cellulose compounds
IPC: D01F2/28
Filed: 1930-03-15
Abstract: Artificial silk, hair, straw, staple fibre, and other threads are obtained by employing, in all the known processes which, without employing baths having a plasticizing effect, produce owing to other conditions artificial threads having a dry tenacity exceeding 2 grams per denier, instead of viscose a product obtained by acting on cellulose xanthate with a substance which has a tendency to react with a compound containing a hydroxyl group, so as to cause introduction of an organic group or radical in place of the hydrogen of the hydroxyl.  Examples of such substances are given in Specifications 335,906, [Class 2 (ii), Cellulose &c.], 341,843, and 357,526.  They include halogen derivatives or other esters of di- or polyhydric alcohols, cyclic ethers of di- or polyhydric alcohols, inorganic esters or halogen derivatives of ethers of monohydric alcohols, halogen derivatives of aldehydes or ketones, halogen olefines or paraffins, halogen fatty acids, halogen derivatives of oxyalkylamines or oxyaralkylamines.  Unripened viscose prepared from unripened alkali cellulose may be employed and the product may be spun with stretching into dilute sulphuric acid.  The viscose may be prepared from cellulose having high viscosity or a high content of alpha-fibre, and the cellulose may be pretreated with dilute acid. In the examples, cellulose xanthate is prepared from high viscosity wood pulp or cotton linters, and dissolved in caustic soda solution. A reagent of the type specified such as a -dichlorhydrin is stirred into the viscose and the solution with or without ageing is spun into dilute sulphuric acid with or without sodium sulphate.  The emergent threads are given an extended air path and are stretched by passing over glass rods placed angularly to one another.  If a high speed of spinning is employed, the additional stretching may be dispensed with.  In another example unripened alkali cellulose produced from highly viscous wood pulp or cotton linters is converted into viscose of high viscosity and then treated with a -dichlorhydrin.  In order to obtain additional stretch, the threads may be passed over rollers rotating at varying speeds.  The threads are washed, and heated or steamed before or after drying.  They may be desulphurized in the ordinary manner or by the process of Specification 341,899.  The extensibility may be increased by treating the threads with shrinking agents.  Specifications 274,521, 274,690, 281,351, 281,352, 312,197, 317,608, 323,731, 323,732, [all in Class 2 (ii), Cellulose &c.], 357,154, and 357,121, are referred to.

Title: Improvements in or relating to the manufacture of cast members adapted to form parts of combustion chambers
IPC: B22D19/00
Filed: 1958-03-18
Abstract: 823,837. Casting composite articles. GENERAL MOTORS CORPORATION. March 18, 1958 [April 2, 1957], No. 8652/58. Class 83 (1). [Also in Group XXVII] A cast member forming part of a combustion chamber, e.g. the cylinder head 18 of a Diesel engine, has non-fusibly cast therein at least one insert 34, 40 of sheet material which extends through, and substantially normal to the surface of, a layer of said member subject, during operation, to severe cyclic temperature changes, said insert or inserts being such as to effect the formation of stress-relieving grooves 37 in said layer adjacent each insert. Under operating conditions, the initial expansive compression imposed on the surface layer of the part stresses this layer beyond its compressive yield point for the temperatures involved, and effects the formation of grooves immediately adjacent to and including the opposite sides of each insert. The inserts are so located that these grooves serve to accommodate and isolate subsequent expansion and contraction of the surface layer from the adjacent critical areas, e.g. intermediate and adjacent the valve ports 24 and injector nozzle opening 26. The units are of a material, or coated with a material, which will prevent fusion with the melt during casting, e.g. high-melting-point metal or ceramic, asbestos, or metal coated with an oxide, ceramic or metallic material, such as rolled sheet steel coated with an iron-aluminium compound. The inserts have a corrugated portion normal to and intersecting the surface layer of the combustion chamber, the corrugations lying parallel to said surface layer. In a casting method, the inserts are mounted in grooves 56, Fig. 8, in the mould by moulding-paste 60, the cast head being subsequently machined, Fig. 10, to the finished head surface.
