Abstract: 546,553. Cellulose-derivative compositions; films; electric lamp polarizers made of synthetic resins. MARKS, A. M. Nov. 6, 1939, No. 29471. [A Specification was laid open to inspection under Sect. 91 of the Acts, May 17, 1940.] [Classes 2 (ii) and 2 (iii)] [Also in Groups XX, VIII and XI] The Specification as open to inspection under Sect. 91 describes laminated polarizers forming part of electric lamps consisting of a pack of from fifteen to thirty sheets of a thickness up to .004 inch, but preferably .0015 inch or less, of a plastic material such as hydrohalogenated rubber (e.g. rubber hydrochloride), halogenated rubber (e.g. rubber chloride), vinyl acetate, acrylates and methacrylates (e.g. methyl methacrylate), cellulose compounds (e.g. nitrate or acetate), cellulose hydrate, urea and phenolformaldehyde condensation products, and glycerol phthalate resins (glyptal resins). The pack of sheets may be sealed at the edges by rubber tape, or by applying a solvent or adhesive. The sheets may be held stretched, or the pack may be formed under reduced pressure to prevent wrinkling due to air expansion between the sheets. The pack may be held between rigid outer sheets of glass or plastic and may be clamped at the edges. The sheets may be joined at intervals by staggered spots of thermo-adhesive or plasticizer, or the adhesive may be applied in the form of sheets having large stamped-out areas. In another form the sheets are bonded and are alternately of high and low optical density, the former of which may be obtained by the addition of a plasticizer or fillers or of mineral or glass particles. Or, relatively large glass plates may be embedded in a sheet of plastic to form the laminations. In one form, cellulose acetate sheets with lead glass particles in alternate sheets are joined in a hot press. For bonding the sheets a transparent thermoadhesive such as cellulose derivatives, resinous thermo-adhesives, or a transparent plasticizer such as dibutyl or ethyl phthalate, triethyl phosphate, or diethylene glycol may be used, also low boiling-point solvents, such as ethyl alcohol mixtures or acetone may be employed. This subject-matter does not appear in the Specification as accepted.

Title: Electron beam fabrication methods
IPC: H01L23/29
Filed: 1972-06-23
Abstract: 1363386 Electron beam apparatus INTERNATIONAL BUSINESS MACHINES CORP 23 June 1972 [30 June 1971] 29562/72 Heading H1D  In an electron resist process of forming a pattern of material on a substrate, the thickness of that part of the substrate on which the pattern is inscribed lies within the range 300-10,000 Š in order to reduce electron scattering in the substrate so that finer lines may be inscribed. The substrate may be of inorganic material such as silicon nitride or aluminium oxide, or an organic polymer. In one example both surfaces of a silicon wafer are coated with silicon nitride by the reaction of silicon hydride and ammonia at 820‹ C., and a photo-resist process is used to remove the nitride on the lower surface in a pattern of rectangular openings of 4-25 mils x 4-25 mils. The exposed silicon is etched up to the nitride surface to leave a nitride film supported by a grid of silicon. An electron-resist such as polymethyl methacrylate is coated over the plane nitride surface and inscribed in a required pattern by an electron beam over the areas overlying the interstices of the grid; after development to remove exposed areas of the resist, a material such as metal is evaporated over the unexposed resist and the exposed substrate, the former part being removed when the remainder of the resist layer is removed. As an alternative, the material may be deposited in a layer on the substrate and coated with an electron resist which is selectively exposed and removed, and the underlying material is removed by etching. The electron resist may be either negative or positive and may be exposed either by scanning or through a suitably shaped mask.

Title: A Method of providing or manufacturing a Tunnel or Culvert or a Lined Passage in a solid medium
Inventor: HEERINGA ALBERT
IPC: E21D9/00
Filed: 1966-07-01
Abstract: 1,154,707. Tunnels &c. A. HEERINGA. 1 July, 1966 [1 July, 1965], No. 29750/66. Heading E1F. In the construction of a channel or tunnel, a section or sections of lining is or are advanced over, or through, a solid material such as earth, by forming a layer of parallel strips extending in the direction of advance between the section or sections and the material, by advancing each strip or a group of strips until the whole layer is advanced, and by advancing the section or sections relative to the advanced layer. A culvert is constructed through a dyke by forming a layer 3 of strips 3a about a section 1, driving one or more of the strips in turn through the ground to advance the layer bodily, and advancing the section relative to the layer. Soil is removed prior to the advance of the section. The strips which may comprise sheet piling or wood may be advanced by a horizontally acting pile driver, or by a tackle connecting the interior of the section, or a group of driven strips, to the strip to be advanced. The section is advanced by jacks reacting on blocks fixed to the layer. After the section is positioned the strips are withdrawn separately. Rollers or lubricant may be interposed between the layer and the section. The layer of ground above the culvert may be held in place by partitions transverse to the direction of advance. In a modification a shield reacting on the strips leads the strips. A tunnel section without floor lining and supported by piles may be advanced by strips extending along the top, or the top and sides, of the section.

Title: Pressure control for fluid systems
IPC: G05D16/18
Filed: 1963-07-26
Abstract: 978,627. Clutch control. TWIN DISC CLUTCH CO. July 26, 1963 [March 13, 1963], No. 29753/63. Headings F2C and F2L. [Also in Division F1] A centrifugal pump 25 taking water from a supply line 28 and delivering it to a pressure line 33 is driven by an electric motor 10 through a friction clutch 24, a regulating valve 35 connected to the delivery line 33 by a connection 53 operating at a predetermined delivery pressure to induce slip in the clutch and so reduce the speed of the pump. The clutch is provided with a pair of pivoted segmental shoes 14 engaged against a drum 12 by springs 21 inside pistons 22 which are subjected internally to the pressure of the liquid in the system. For cooling purposes the curved engagement surfaces of the shoes 14 are formed with localized projections 20, and in addition the supply liquid is fed through a pipe 29 to a casing 30 surrounding the clutch drum 12, circulation being promoted by openings 21 in the end wall of the drum. At starting the shoes 14 are subjected chiefly to the loading of springs 21 and the clutch slips, but sufficient torque is transmitted to actuate pump 25, and as the speed and delivery pressure rise centrifugal force on shoes 14 and fluid pressure acting on pistons 22 eliminate the slip. At the predetermined delivery pressure valve 35 lifts against its loading spring 44, to uncover a port 62 by which the pressure liquid is vented into casing 30 and thus induces slip to reduce the pump speed.
Patent GB-645275-A (GB)
Title: Improvements in or relating to filaments of thermoplastic material and manufacture thereof
IPC: D02J1/22
Filed: 1947-11-08
Abstract: A normally crystalline vinylidene chloride polymer or co-polymer is extruded in molten condition into a chamber 30-50 feet high, the temperature at least in the upper portion being about 200 DEG  F., and the filaments obtained are elongated in the chamber by the tension exerted by their own weight.  If desired, the filaments may be maintained in a hot plastic condition for only a short part of their vertical travel and may then be cooled so as to become solidified in amorphous form during the remainder of their vertical travel.  Copolymers of vinylidene chloride with vinyl chloride or acetate may be used.  Plasticizers, pigments, and other ingredients may be included in the composition.  As shown in the Figure, the vinylidene chloride polymer is supplied through hopper 10 to an extrusion device 17, provided with extrusion screw 15 and heating devices to bring the material to the desired state of plasticity or viscosity for extrusion.  The material may be heated gradually to about 320 DEG  F.  It is extruded through spinneret 21 into chamber 24.  Relatively large orifices may be used.  Heated air may be passed through the long chamber 24 to maintain a temperature of 200 DEG  F. and keep the extruded filaments in a plastic state during their entire travel through the chamber.  The weight of the filaments causes them to elongate to a high degree.  The filaments 23 are passed into bath 27 containing a quenching liquid, e.g. water or oil, at 40-50 DEG  F. The filaments then pass into a second bath 32 which may contain talc, aluminium stearate, or other powdered lubricant. The filaments are then wound on reel 34.  The filaments when in the amorphous unoriented state are stored at temperatures below 50 DEG F. If desired, the filaments 23 may pass from bath 27 to a system of stretching rolls which subject them to elongation accompanied by molecular orientation with increase in tensile strength.  If desired some of the weight of the suspended length of the filaments may be prevented from acting on the hot plastic portion. For this purpose the lower end of chamber 24 may be closed and hot water or other liquid may be passed through the chamber to support partially the filaments.  The chamber 24 may be divided into two compartments, the upper and shorter one being heated to about 200 DEG  F., and the lower one being heated only to about 50 DEG  F., so as to prevent crystallization of the resin in an unoriented manner while in the chamber.  The polymer may be a copolymer of 5-15 per cent <PICT:0645275/IV (a)/1> vinyl chloride with 85-95 per cent of vinylidene chloride.  The Specification as open to inspection under Sect. 91 comprises also the production of filaments from other thermoplastic materials.  This subject-matter does not appear in the Specification as accepted.
