Title: Method of treating the surface of wood
Inventor: DIMOND LLOYD EMIL
IPC: B27K3/10
Filed: 1957-12-30
Abstract: The flat surface of wood or other cellulosic products presenting a smooth regular porous firm heat-insulating surface containing a heatplasticizable material is glossified by rubbing the said flat surface with a fast moving rubbing <PICT:0861347/III/1> medium having a flexible substantially unabrasive heat-insulating frictional rubbing surface which moves toward and away from said flat surface through a concavo-convex path with the convex side intimately and firmly pressed by a backing member against said flat surface while traversing it, controlling the magnitude of the traversing speed to provide rubbing contact of momentary order at successive areas of said flat surface, and correlatively controlling the magnitudes of the rubbing pressure against, and the rubbing speed relatively to, said flat surface at values causing said rubbing medium to generate frictional heat on said flat surface at the elevated temperature level required for plasticizing the said heat-plasticizable material without plasticizing the underlying material throughout its depth and to glossify said flat surface during said contact time.  The surface may first be coated with a surface-penetrating plastic and finishing additive having the properties of being heatplasticizable at temperatures elevated substantially above room temperature and in a hardened state at room temperature after heat-plasticization, and then subjected to the glossifying operation.  Suitable plastic materials include phenol-formaldehyde resins, melamineformaldehyde resins, urea-formaldehyde resins, heat-convertible alkyd resins, and polyester resins; also thermoplastic materials such as polyamides, vinylidenechloride - acrylonitrile resins, trifluoro chloroethylene, vinyl chlorideacetate resins, vinyl formal resins, methyl methacrylate resins and polymethyl alphachloro acrylate resins.  The coating may be applied by brushing, spraying, or rolling a suspension or solution of plastic on to the surface, and the solvent is allowed to evaporate before glossifying.  As shown, a panel 4 to be glossified travels along a conveyer 1, 2 under a roller 15 which is weighted so as to apply pressure thereto.  An endless belt 12 composed of cork or containing a cork surface arranged around two drums 10, 13 is pressed against the underside of the wooden panel at a point opposite to the feed roller.  The drums rotate so as to move the endless belt in a direction opposite to the direction of motion of the wooden panel.  The speed of rotation of the rollers 10 and 13 is such that the linear speed of the endless belt is considerably greater than that of the wooden panel.  Instead of the endless belt other means such as a cylindrical cotton buffing wheel having an axial length equal to or exceeding the width of the surface to be treated may be used.

Title: Process for production of alcohols from olefin
IPC: B01J37/20
Filed: 1961-11-14
Abstract: Alcohols are prepared by the hydration of olefines using a catalyst consisting of silica with alumina, magnesia, titania, zirconia or thoria which has been previously contacted with hydrogen sulphide, or other gaseous sulphur-containing compound which decomposes to give hydrogen sulphide under the contacting conditions, at 100-2000 DEG F. so as to avoid sintering of the catalyst, the catalyst being such that it does not react with hydrogen sulphide nor has sulphur deposited on it and is free of metals which react with hydrogen sulphide to form metal sulphides. Suitable sulphur-containing compounds which decompose to hydrogen sulphide under contacting conditions are, for example, propyl sulphide and propyl mercaptan. The hydrogen sulphide may be mixed with a diluent gas, e.g. hydrogen. Suitable hydration conditions are a temperature of 250-700 DEG  F. and a pressure of 400-10,000 lbs./sq. inch gauge and the process may be carried out in either batch or continuous operation.  The preferred catalyst is silica-alumina. Examples are given of the hydration of propylene and n-butene-2.ALSO:A catalyst for use in the production of alcohols by the hydration of olefines consists of silica with alumina, magnesia, titania, zirconia or thoria, which has been contacted with hydrogen sulphide, or other gaseous compound which decomposes to give hydrogen sulphide under the contacting conditions, at a temperature of 100-2000  DEG F., so as to avoid sintering of the catalyst, the composite catalyst material being such that it does not react with hydrogen sulphide, nor has sulphur deposited upon it and is also free of metals which are chemically reactive with hydrogen sulphide to form metal sulphides.

Abstract: 1,181,557. Packaging-machines; endless conveyers; grippers; suction heads for lifting articles. DR. CARL HAHN K.G. 6 Sept., 1967 [6 Sept., 1966], No. 40780/67. Headings B8A, B8C and B8H. [Also in Division F4] A machine for packaging elongated articles, e.g. cotton-wool tipped sticks, comprises groups of grippers on a rotary turret which each lift a batch from an infeed conveyer and deposit it in a box on an adjacent turntable, the arrangement being such that, as one group is depositing its load, so that group following it is picking up the next batch. Several batches may be deposited in each box. In one embodiment, each gripper head 22 comprises a vertically slidable carriage 24 to which is secured a block 43, Fig. 3. Comb-like elements 48 having teeth 50 depend beneath the block in which are rotatable vertical gripper rods 44 in a row between the two rows of teeth 50. The upper ends of the rods 44 are linked for uniform rotation to a bar 42, the bar being secured to a connector 38. The rods 44 are rotatable through 90 degrees from a position, Fig. 4, in which they pass between alternate cotton-wool sticks 52 to a position in which they grip the sticks by grooves 58 against the comb teeth 50 which occupy the remaining spaces between the sticks, Fig. 6. To release the sticks, the movements are reversed. An ejector 180, spring-biased downwards, engages the sticks to ensure their ejection when released. The connectors 38 of adjacent heads are joined by relatively stiff cables 30b, slidable in fixed coverings 30a to levers 32 having cam follower rollers 33, 34 on their ends. In operation, sticks are fed in by an intermittently movable conveyer 54 and a batch is raised clear of it by blades 82 on rotary members 70. A head descends so that the teeth and rods pass between the raised sticks. A plunger 96, Fig. 1, then presses a cam-piece 106 between adjacent followers 33, 34, shifting the connector 38 anti-clockwiae, as shown, to cause gripping of the sticks. The previously loaded head, now located over a turntable 11 on which the boxes 13 are carried and which descended at the same time as the head over conveyer, to place its load within a box, releases its load, the respective connector 38 being shifted clockwise by the cam-piece 106. Each box is located on the table 11 by wedgeshaped elements 176, having leaf springs (175), Fig. 10 (not shown), to one side, and pins 178. In an alternative embodiment, Figs. 7, 8 (not shown), simple suction grippers may be used. An arcuate manifold (180) blowing hot air into the loaded boxes to dry the contents may be arranged above the table, Figs. 11, 12 (not shown).

Abstract: 966,899. Production of a vapour containing two components in constant proportion to one another; crystallizing. FERRANTI Ltd. Nov. 8, 1962 [Nov. 16, 1961], No. 41013/61. Headings B1B and B1G. In a continuous process for the production of a vapour containing two components in substantially constant proportion to one another, particularly in the manufacture of crystalline material for transistors, wherein a stream of an inert carrier gas is passed through a zeotropic liquid mixture of the two components, the carrier gas stream is initially passed through a subsidiary evaporator containing the more volatile liquid, maintained at a lower temperature than the liquid mixture in the main evaporator, the difference in temperature between the two liquids being such that the ratio of the two components in the liquid mixture in the main evaporator is maintained at a constant value. An example relates to the growth of a layer of silicon doped with phosphorus, on a silicon substrate mounted in cell 1. Pure hydrogen flows through flowmeter 6 and valve 5 into evaporator 4, which contains liquid silicon tetrachloride at 12 ‹C. The hydrogen leaves evaporator 4 saturated with silicon tetrachloride vapour at 12 ‹C., and passes into the main evaporator 3, which contains a liquid mixture of silicon tetrachloride and phosphorus trichloride at 20 ‹C. in a predetermined ratio to one another. The hydrogen leaving evaporator 3 is saturated with both silicon tetrachloride vapour and phosphorus trichloride vapour in the required proportion to one another, and is passed into the deposition chamber 1 via valve 2. The process may also be used to produce vapours which contain germanium tetrachloride.
