Title: Ice-skating rink
IPC: E01C13/10
Filed: 1949-09-15
Abstract: 662,514. Ice rinks. YOCUM, R. J. Sept. 15, 1949 [July 11, 1949], No. 23789/49. Drawings to Specification. Class 20(i) To provide markings on an ice rink, e.g. the goal lines in a ice-hockey game, strips of light conducting material which may be methyl methacrylate resin in particular- "Lucite," extend across the rink beneath the ice and are illuminated by lamps, at the end of the strips and lowered in a recessed portion of the rink sidewall. Those parts of the strip which are not required to be visible are covered with an opaque sheathing, possibly metal. The strip need not extend completely across the rink but the lamps must be situated near the ends of the strips. In a modification the strips are situated beneath a glass sheet above which are refrigerant tubes which are preferably of transparent material embedded in ice. The invention may be used in conjunction with the lighting arrangement described in Specification 651,381.

Title: Automatic felting machines and processes
IPC: D21J5/00
Filed: 1963-06-17
Abstract: 1,042,982. Moulding fibrous pulp articles. HAWLEY PRODUCTS CO. June 17, 1963 [Oct. 10, 1962], No. 23971/63. Heading B5A. Fibrous pulp articles, such as cones, are preformed by suction of a fibrous slurry on to foraminous moulds 49, Fig. 2 (not shown), by lowering and raising the moulds within a slurry tank 2. The articles are transferred from moulds 49 by mating foraminous dies 78, Fig. 5, mounted on plates 79, which are vertically reciprocated and simultaneously caused to invert by suitable pivoting 101, 102 and the provision of cam tracks 95, 104. In operation, the plates 79 are alternately lowered each time moulds 49 are raised and the articles are picked up on dies 78 by suction to be transferred on inversion to heaters 68. By having two plates 79, alternately reciprocated, the drying time for each article is doubled. The dried articles are ejected sideways by air pressure as a plate 79 is lowered and reaches a vertical position. The driers 68 may operate by drawing hot gases or superheated steam through the articles or by using heated dies which may be mounted on brackets 77, Fig. 9 (not shown), within the drier casings. Also described is an automatic system which replenishes the fibre and controls the consistency of the fibre slurry, Fig. 10 (not shown).

Abstract: A synthetic resin for use in paints, varnishes and baking enamels is the reaction product of a copolymer of an unsaturated monocarboxylic fatty acid and a monovinyl aromatic compound, a polyhydric alcohol and a polysiloxane containing alkoxy groups, and/or halogen atoms. The resin may be made by reacting the siloxane with the alcohol and with the copolymer, but is preferably made by reacting the alcohol with the copolymer and reacting the resulting ester with the siloxane.  There are specified (a) monovinyl aromatic compounds-styrene, a  - methylstyrene, p-methylstyrene, a -p-dimethylstyrene, divinylbenzene, vinylnaphthalene, acenaphthylene, vinyltoluene, p-chlorostyrene, p-trichloromethylstyrene, 2 : 5-dichlorostyrene, p-methoxystyrene or mixtures thereof; (b) unsaturated fatty acids-acrylic, methacrylic, vinylacetic, hydrosorbic, decenoic, undecylenic, sorbic, hiragonic, linoleic, isolinoleic, elaeostearic, punicic, parinaric, arachidonic, clupanodonic, scoliodonic, nisinic, tariric, abietic and licanic acids; castor-, linseed-, soyabean-and tung-oil fatty acids, rosin acids and tall oil acids; the dimers and trimers of these acids may also be used; (c) polyhydric alcohols-ethylene-, diethylene-, propylene- and trimethylene-glycols, glycerine, trimethylol propane, pentaerythritol, polyallyl alcohol, sorbito-and mannitol.

Title: A method of production of artificial stones for building purposes
IPC: B28B11/14
Filed: 1944-12-01
Abstract: Porous building-blocks are produced by placing in a mould a mass of stone-forming composition of the kind containing substances which react chemically to produce bubbles of gas in the mass and, after fermentation and while the mass is still in a plastic state, sawing the mass into blocks.  The mould may have four walls which can be swung down to expose the plastic mass. First two opposite walls are swung down and saw-cuts are made in one direction, then those two walls are swung up and the other two walls swung down, then saw-cuts are made at right-angles to the previous ones, and finally the second two walls are swung up, the mould walls are clamped together, and the blocks are hardened by steam in an autoclave.

Adjustment for current setting may be effected by sliding a member 6 along the end of a bimetal strip s, the position of the member 6 being determined by a projection engaging one of two recesses. The sleeve m may consist of several portions which may be fixed or rotatable. The trunnion y on the arm d, engages a fixed slot z, and normally occupies the position shown. It may, however, be pulled by hand into the dotted position to allow the contacts to be exposed.

Title: Improved process for the removal of diolefins from hydrocarbon mixtures containing the same
IPC: C07C9/16
Filed: 1944-12-11
Abstract: Diolefins are removed from an olefinic feed containing mono- and di-olefins by contact, in gas or vapour phase, with an acid-treated clay, Attapulgus clay, bauxite or a solid phosphoric acid-kieselguhr catalyst at above 700 DEG  F., the product being cooled, and liquid polymers of diolefins separated.  Temperatures are generally 700-900 DEG , preferably 800 DEG  F., and pressures 25-200, preferably 50 p.s.i.  Contact times may be 4-40 secs.  A C4 cut may be treated to obtain isobutene free from butadiene for alkylating isobutane or to remove butadiene prior to solvent extraction, for example of isobutene with phenol or cresol.  The preheated feed may be passed down through the catalyst, and the products passed to a separator at reduced temperature and pressure to separate liquid polymer.  The olefins may then be used to alkylate isoparaffin with 90-98 per cent sulphuric acid as catalyst.  Results are given of the treatment of C4 cuts with Attapulgus clay, bauxite and "Super-Filtrol" (Registered Trade Mark).

Patent GB-978070-A (GB)
Title: Reduction of metal oxides
IPC: C21B13/00
Filed: 1963-06-24
Abstract: A reducible metal oxide is reduced to metal, particularly iron ore to pig iron in a blast furnace, by contacting the oxide in particle form in a reduction zone with a reducing gas generated separately and externally of the reduction zone and comprising carbon monoxide, hydrogen and acetylene.  The gas is preferably formed by reacting preheated hydrocarbon gas, such as methane, ethane, propane, butane or natural gas preheated to above 600  DEG F., with oxygen-containing gas, such as oxygen preheated to at least 600  DEG F. or air preheated to at least 1500  DEG F., in a separate reaction zone for 0.005-0.05 second. As shown in Fig. 1, a blast furnace 2 is charged with iron ore, coke and limestone and supplied with preheated air or oxygen-enriched air through tuyeres 12, gas being discharged through line 13 for processing. According to the invention, the reducing gas, containing 1-4 mol per cent acetylene, is generated in acetylene generators 14 located around the furnace away from the tuyeres to prevent burning and fed directily into the stack 18 preferably where the temperature is above 1600  DEG F.  Alternatively, the reduction with actylene-containing gas may be carried out in an ore reducer shaft-type furnace in which a downwardly moving settled bed is maintained (see Fig. 2, not shown), the reducing gas similarly generated flowing upwardly counter-current to the particulate ore and being recycled and reformed by reaction with additional hydrocarbon gas.  A fluid or fixed bed type reduction furnace may be used or possibly the reduction may be carried out in a rotary kiln.
