Title: Improvements in coin-testing devices
IPC: G07D5/04
Filed: 1928-09-10
Abstract: 322,769. Turner, H. Sept. 10, 1928. Testing coins.-In a coin testing device of the kind having upper and lower pivoted members adjustably balanced and arranged one to cause an overweight coin and the other to permit a normal-weight coin to drop through, the tilting levers j, k, Fig. 2, bear at their face ends j<2>, k<2> against the underside of fixed plates c, d, which have inclined top surfaces, so as to prevent the free ends from rising above a position in which the top surfaces of the levers are aligned with the tops of the fixed plates, the tilting levers being independently supported from the underside by pivoted controlling members m. The levers j, k are pivoted at j<1>, k<1> between a plate a and a cover plate, the plates c, d and a guide plate b being also secured between the two plates. The supporting arms m are carried by brackets pivoted on the spindles j<1>, k<1> and have cranked ends, extending through slots q, q<1> in the plate a and its cover, to come beneath the levers j, k. The carriers for the arms m are provided with bob weights o adjustably secured to the carrier by screw-threaded stems p. A coin of correct weight inserted at g runs over the lever and around a bend d', the end j' of the lever reducing its velocity. It then runs over the lever k, which it depresses against the action of the bob weight d, and passes through an outlet h. If the coin is too heavy it tilts the lever and passes out through an opening i. A light coin fails to tilt the lever k and also passes through the outlet i.

Abstract: 937,835. Blanks transferring; stamping. S.A. DES USINES CHAUSSON. July 26, 1960, No. 25977/60. Classes 83 (3) and 83 (4). Apparatus for continuously transferring workpieces from a machine 1, Fig. 1, to a machine 2 includes a pivoted pincers device which automatically grips all the workpieces in the space between the machines, moves them along a distance equal to the forward stroke of a reciprocating table, releases them while the table returns and then continues so that there is a continuous succession of workpieces passing between the machines. The invention applies more particularly to transfers between machines used in the manufacture of cooling radiators to effect the transfer between two stamping points of the water boxes of these radiators. The apparatus is mounted on a movable carriage 3 and comprises a framework 6, 12, Fig. 4, which is provided with guide rails 14 for the reciprocating table 19 and brackets 15 to support a drive housing 16. A motor 7 drives a vertical spindle in the housing 16 and a clutch 10 transmits motion to a crank 32. The end of the latter is connected by a pin 34 to the middle of a connecting-rod 35 one end of which engages a pin 36 coaxial with the drive-shaft and rotatable in a bearing in the table 19. The other end of the connecting-rod carries a roller 39 which, during part of the rotative cycle of the crank, engages transverse slots 17, 18, in a fixed part of the frame and thus becomes a fulcrum to give reciprocating movement to the carriage 19. Arms 43, 44, pivoted to the frame, are interconnected by rods and cranks and moved in timed relation with the table by a cylinder and piston device so that the arms are moved inwardly and outwardly to grip and release the workpieces. Beams 45, 46, secured to the ends of the pivoted arms carry work-gripping members 47, Fig. 1, spaced along the beams at intervals equal to the stroke of the carriage. Stationary rails or tubes 53, 54, support the workpieces when released by the pincer members 47. When a workpiece reaches the final stroke position, adjacent machine 2, fingers 56 on the ends of the beams 45, 46, push it into the working position of the machine.

Title: Method for the production of silicate melts opacified with zirconium oxide
IPC: C03C4/00
Filed: 1938-09-06
Abstract: 507,823. Enamels and glazes; glass manufacture. AUERGES. AKT.-GES. Sept. 6, 1938, No. 26095. Convention date, Sept. 14, 1937. [Class 56] Relates to silicate melts, such as glasses, glazes, or enamels, which are opacified by zirconium oxide and are subjected to prolonged heat treatment during manufacture. According to the invention, the composition of the melt is so selected that the zirconium oxide is not absorbed, or does not form double compounds with constituents of the melt, under the prolonged heating. In particular, with aluminous silicate melts, the proportions of silica and alumina should not exceed seven to one. The zirconium oxide can be pro-' duced during fusion from double compounds which yield the oxide under heat, for example, sodium-zirconium silicate or lead zirconate. The materials of the melt may be fused with an excess of zirconium oxide, and the resulting product pulverized when cold and added to a melt of different composition to secure the desired final product.

Abstract: 1326261 Treating fibrous goods with solvents CIBA-GEIGY Ltd 29 May 1970 [2 June 1969 20 June 1969] 26151/70 Headings D1L and D1P In a method of treating fibrous goods in a container with an organic solvent having an s.g. greater than 1 and which is partially immiscible with water and forms at least partially an azeotrope therewith, the vapours evolved during processing are condensed and returned to the container via a pump or similar emulsifier, after removal of any undesired water. Fabrics of polyester or polyamide may be dyed in this manner using perchloroethylene as solvent. Excess vapour pressure may be avoided by using a closed, valved treatment vessel or by controlling the condensation capacity of the condenser. After processing, the fabric may be immersed in water (e.g. to dissolve out ionic substances present) and then heated to recover the solvent azeotropically. The treatment liquor may be non-aqueous, in which case any water absorbed from the goods during treatment is removed during recycling, or may be an aqueous emulsion in which case the water is also recycled. Conventional rotary drum apparatus, but incorporating a pump and condenser, may be used.

Title: Method of recovering sodium salts in the manufacture of cellulose by digestion according to the sodium sulphite and/or sodium bisulphite methods
Inventor: LARSSON ERIC JOHAN
IPC: D21C11/00
Filed: 1948-10-08
Abstract: In recovering sodium salts in the manufacture of cellulose by the sulphite or bisulphite method by combustion of the evaporated liquor, the molten mass thus obtained is dissolved in a suitable solvent, e.g. water, and carbon dioxide is introduced in one or more steps to a point near or slightly beyond the limit of solubility of the bicarbonate, the solution is heated and the hydrogen sulphide formed is boiled off, preferably under reduced pressure, and carbonation is continued till bicarbonate crystals form, which are then separated from the liquor.  The hydrogen sulphide boiled off may be converted into sulphur dioxide which may then be reacted with the bicarbonate for the preparation of new digestion liquor with consequent evolution of carbon dioxide which may be used for carbonating further quantities of the dissolved molten mass.  The condensate from the washing of the gases from one or more soda-furnaces may be used for dissolving the molten mass, and the solution from the last step may either be used for the same purpose or be supplied, wholly or in part, to the liquor intended to be burned.  The solution obtained during carbonation may be freed from silicic acid, e.g. by filtration.

Filed: 1961-07-26
Abstract: <PICT:0929929/III/1> <PICT:0929929/III/2> <PICT:0929929/III/3> In a process for the continuous manufacture of titanium di- and tri-chlorides from titanium tetrachloride using hydrogen as the reducing agent, the hydrogen is preheated to above 1000 DEG C. and 1,2 to 20 times the theoretical amount is mixed rapidly in the gaseous phase with titanium tetrachloride in a mixing zone which is kept at temperatures between the boiling point of titanium tetrachloride and 500 DEG C.  The reaction products are chilled in the absence of air on a moving cooled surface from which the resultant deposit is continuously removed and collected under an inert atmosphere.  Preferably the chloride is vaporized under such a pressure that the vapour is brought into contact with the preheated hydrogen at a relatively high speed.  To increase this speed additional hydrogen may be admixed.  In the apparatus shown, see Figs. 1 and 2, hydrogen introduced at 13 is preheated on its passage through an electric arc between cathode 4 and anode 5 and is then mixed in nozzle 6 with gaseous titanium tetrachloride introduced radially through feed pipe 14.  Alternatively the chloride vapour may be tangentially introduced.  The reaction products strike the moving cooled roller 1 surrounded with casing 2 provided with cooling jacket 10, the roller being cooled by spraying water or oil at a temperature of 50 DEG C. to 300 DEG C. from perforated pipe 7 against that segment of roller 1 which is nearest to the mixing nozzle.
