IPC: B23K11/00
Filed: 1948-09-06
Abstract: 645,543. Making tubes. WELLMAN SMITH OWEN ENGINEERING CORPORATION, Ltd. Sept. 6, 1948, No. 23466. [Classes 83 (ii) and 83 (iv)] Rolling.-A process for the manufacture of tubes comprises producing a butt-welded tube by a known method, inserting a mandrel into said tube and thereafter treating the tube in rolls or dies. The apparatus comprises shears 4 and flash welder 5, whereby ends of successive coils of strips 2 may be joined, pinch rolls 6, continuous furnace 8, butt weld former 9 and sizer 10, and a flying saw 12 by which the tube 11 may be cut into lengths. The butt-welded tubes are transferred by skids 15 to a feeder table 14, facing at its rear end a mandrel threader 17 and at the other end a rolling mill 16. After insertion of a mandrel bv a striker on an endless belt or chain 35, the tube is moved through the mill 16 on to a run out table 18, from which it is transferred to a feed table 19, the mandrel being thereafter extracted by mechanism 21 and returned by way of table 22 to the threader 17. The sizer 10 may be omitted. It is stated that heavier walled tubing than normal may be made in the butt welder 9 and that the finished tubes may be thinner walled than has heretofore been possible.

Title: Method for production of deuterated methanes and heavy water
Inventor: POGORSKI LOUIS AUGUST
IPC: F25J3/02
Filed: 1965-06-02
Abstract: Heavy water is obtained by oxidizing with air or oxygen a methane fraction enriched in deuterated methanes and obtained by low temperature fractionation of a methane-containing gas (see Division C5), the oxidation product being a mixture of oxides of deuterium, hydrogen and carbon.  This mixture may then be liquified and degassed, and the degassed mixture treated to concentrate the heavy water therein, e.g. by distillation or electrolysis.

Title: An improved distributing or allocating element for central lubricating plants
IPC: F16N27/00
Filed: 1952-09-23
Abstract: 708,795. Lubricating. SCHMEMANN, A., [trading as DE LIMON FLUHME & CO.] Sept. 23, 1952 [Oct. 13, 1951], No. 23801/52. Class 12(3) The body 1 of an element for allocating lubricant from a central lubricating plant to one of a number of lubricating points has a bore 3 closed at both ends and communicating through openings 11, 15 on the body 1 with the pump for lubricant and the part to be lubricated, respectively. The bore 3 contains a piston 2 formed with a bore 8 to receive a spring-pressed hollow control piston 10. The stroke of the piston 2 is limited by stops 16, 17, the stop 17 being eccentrically secured to a rotatable shaft 24 so that its position may be adjusted. Lubricant under pressure passes through the inlet 11 and through a passageway 13 into the bore 8 and displaces the control piston 10 so that the bore 8 communicates by channels 20, 21 with the chamber 3. Both pistons 2, 10, are then moved downwardly and lubricant is expressed from the chamber 6 through the outlet 15 to the part to be lubricated. Pressure is then relaxed on the conduit 12 and the spring 9 presses back the pistons 2, 10, the passage 19 on the piston 10 communicating with the channel 20 whereby lubricant above the piston 2 is caused to move down to the chamber 6 in position for subsequent discharge at the next cycle of operations. In a modification the bore 3 is closed at the bottom by a member formed with a passage for lubricant to a part to be lubricated, the outlet 15 being closed by a plug.

Title: Improvements in or relating to resin-sand mixes for moulding
Inventor: LEMON PETER HERBERT RICHARD BR
IPC: B22C1/22
Filed: 1956-08-02
Abstract: A dry, free flowing, resin coated sand for use in making shell moulds is prepared by coating individual particles of sand with a non-solvent plasticizer, adding powdered thermosetting resin and coating the resulting resin coated sand with a layer of wax by treatment, without heating, with a solution or dispersion of the wax in a volatile solvent.  The non-solvent plasticizer is one which does not dissolve or swell the resin in the cold, but which dissolves it at 200-250 DEG C., and has low viscosity and volatility, e.g. a diester of phthalic acid with an aliphatic monohydric alcohol, for example, dibutyl phthalate.  The non-solvent plasticizer is used in amount 0.1-0.6% wt. of the sand.  The thermosetting resin, e.g. a phenol formaldehyde resin of particle size such that only 5% is retained on a 200 mesh screen, is used in amount 2-10% wt. of the sand.  Waxes, in amount 0.05-0.5% of the sand, include paraffin or carnauba wax, Japwax, or Acrawax dissolved or suspended in aromatic solvents, e.g. benzene, toluene, xylene or solvent naphtha or in other solvents, e.g. white spirit or turpentine.  A dispersion of carnauba wax in benzene is preferred.

Title: Manufacture of compounds useful for protection against moths
IPC: C07D209/38
Filed: 1933-08-30
Abstract: Products useful as mothproofing-agents are prepared by condensing isatin, or a Bz-halogenisatin which may be sulphonated, or a N-alkyl- or N-aralkyl-isatin which may be halogenated or sulphonated, with a homologue or derivative of phenol substituted in the nucleus by an alkyl group of at least three carbon atoms or by one or two halogen atoms or by an alkyl group and halogen.  The products are sulphonated, if necessary, to render them soluble in water.  In the examples: (1) N-oxyethylisatin-5-sulphonic acid and amyl-cresol are heated in the presence of sulphuric acid; (2) N-oxyethylisatin-5-sulphonic acid and 6-chloro-m-cresol are heated in the presence of sulphuric acid; (3) N-benzylisatinsulphonic acid and thymol are heated in the presence of hydrochloric acid and stannic or zinc chloride; (4) N-benzylisatinsulphonic acid and amylphenol are heated in the presence of hydrochloric acid and stannic chloride; (5) N-benzylisatinsulphonic acid and 6-chloro-m-cresol are heated in the presence of hydrochloric acid and stannic chloride; (6) N-o-chlorobenzylisatinsulphonic acid and thymol are heated in the presence of hydrochloric acid and stannic chloride; (7) N-o-chlorobenzylisatinsulphonic acid and 6-chloro-m-cresol are condensed as in example 6; (8) 6-chlorisatin-5-sulphonic acid and p-chlorophenol are heated in the presence of sulphuric acid; (9) 5 : 7-dibromisatin and o-chlorophenol are heated in the presence of sulphuric acid and the product is sulphonated. N-oxyethylisatin-5-sulphonic acid, used in examples 1 and 2, is prepared by treating sodium isatin with glycol chlorhydrin and sulphonating the product with oleum. N-benzylisatinsulphonic acid, used in examples 3--5, is prepared by sulphonating N-benzylisatin. N-o-chlorobenzylisatinsulphonic acid, used in examples 6 and 7, is prepared similarly to N-benzylisatinsulphonic acid.  6 - Chloroisatin - 5 - sulphonic acid, used in example 8, is prepared by sulphonating 6-chloroisatin, which is obtainable from m-chloraniline by the method of Specification 128,122, [Class 2 (iii)].

Abstract: 814,863. Seats. BRAUN, F. July 30, 1957 [July 31, 1956], No. 24151/57. Class 52(2) A seat has a leg rest pivotable from a retracted position beneath the seat to an extended position, the leg rest being constantly urged away from the retracted position by a spring and lockable by means manipulable by the occupant of the seat. As shown in Fig. 3, the leg rest 2 is pivoted to the seat 1 at 3 and is further connected to the seat by links 9, 11 which are connected at the common pivot 10 by a cable 21 to one end of a tension spring 6 mounted on the leg rest. The tension spring may be replaced by a compression spring. Locking the leg rest in adjusted position is effected by a pin passing through a hole in the link 11 and one of a corresponding series of holes in the member 13 secured to the underside of the seat. The pin is connected through a Bowden wire to a control operable by the occupant. An extension 18 sliding within the leg rest in grooves 20 is provided (Fig. 6) and in the embodiment shown is automatically extended on raising the leg rest. A compression spring 6 bears on the extension 18 which carries a member 25 to which the cable 21 is secured. A weaker spring 23 inside spring 6 also bears on member 25 The spring 6 partially raises the leg rest and opens the extension 18 and the spring 23 completes the operation.
