Title: Method and device for putting so-called facing disks or spots into bottle caps
IPC: B21D51/46
Filed: 1934-02-23
Abstract: 433,959. Making bottle caps. JONSSON, A. J., Link÷ping, Sweden. Feb. 23, 1934, No. 6032. Convention date, Feb. 25, 1933. [Class 125 (iii)] In a machine for making bottle caps, the facing discs are cut out of a blank strip laterally and at a distance from the caps and sealing discs and are centred on and fixed to the sealing discs by an adhesive. A cap punching device 1 delivers caps through a groove 2 to a cork indenting tool 3. The cork discs are delivered from a tube 4 by a conveyer 5 which is reciprocated by gearing 6. A safety device 14a stops the machine when an imperfect disc or no disc is supplied. The facing discs are punched from strip delivered from a device 10. A conveyer 18 feeds the facing discs to the tool 3. The assembled caps are heated by an electrical heating element, and the adhesive, e.g. guttapercha is thereby caused to stick the discs to the cap.

Title: Method and apparatus for linearly conveying wheeled vehicles
IPC: B60S3/00
Filed: 1976-02-17
Abstract: 1534756 Reciprocating conveyers for moving wheeled vehicles J H GRAY 17 Feb 1976 [9 May 1975] 06130/76 Heading B8A A vehicle is conveyed through a car wash, or parking bay, by being run on to rails 18, 19, at least one of which is associated with a series of pawls 20. The latter are gravity-biased, by respective weights 26, to a position in which they engage behind a wheel or wheels of the vehicle. The wheel or wheels so engaged, is or are thereby prevented from rotation, and as the plate 18 is reciprocated forwardly by the action of an hydraulic jack unit 38, the vehicle is carried forwardly. As the plate 18 is reciprocated rearwardly, the vehicle remains in its forward position, and it is again pushed forwardly on the next forward movement of the plate 18. At first (Fig. 5a, not shown), only the front wheel is engaged by the pawls 20, but as the vehicle moves further on to the conveyer, the rear wheels are also picked up by the pawls (Fig. 5e, not shown). As shown, a rail 18 and associated pawls 20 are provided for the wheels on only one side of the vehicle. There may however be pawls 20 engaging the wheels on both sides of the vehicle. The pawls 20 may alternatively be spring loaded, but may be in the form of fixed wedge-shaped blocks, the wheel riding up over each block on the rearward movement of the latter.

Patent GB-847772-A (GB)
Title: An improved method of solvent dewaxing
IPC: C10G73/06
Filed: 1959-02-24
Abstract: A process for dewaxing mineral oil comprises diluting the oil with a solvent consisting of (by vol.) 20 to 40% methyl ethyl ketone (MEK) and 80 to 60% methyl isobutyl ketone (MiK).  The preferred MEK:MiK ratio is 30:70, particularly for an SAE 60 oil; the proportion of MEK is advantageously increased for a lighter oil and decreased for a heavier oil.  Process diagrams are given for the operation of the process with dehydration of the solvent and without complete dehydration.  Ketone distillation.  The ketone mixture is separated from the oil by steam distillation which yields a wet ketone mixture. In the subsequent distillation of the wet ketone mixture in a column a water-containing ketone stream is obtained overhead and a water-free ketone stream is withdrawn from a lower portion of the column.  The methyl isobutyl ketone acts as an extractive solvent enabling anhydrous methyl ethyl ketone to be obtained by distilling the mixture.  A process diagram and a phase diagram for the ketone dehydration are given. Specifications 602,271 and 709,732 are referred to.

Title: Improvements relating to the depolymerisation and hydrogenation of natural, synthetic and vulcanized rubber
IPC: C08C19/02
Filed: 1937-03-09
Abstract: Synthetic oils completely saturated with hydrogen and unattacked by sulphuric acid, which are suitable for mixing with lubricating, animal and vegetable oils, are obtained from rubber, vulcanized rubber scrap, balata, and like highly-polymerized unsaturated hydro-carbons by subjecting the crude materials in the liquid phase to high pressure and temperature in the presence of a ring-closure retarding agent, viz. caustic soda, hydrated lime, metallic sodium, or sodium hydride, preferably in the presence of a solvent, and subjecting the product to hydrogenation in the liquid phase in the presence of catalysts, e.g. copper chromite. The products from the first stage are preferably treated to remove combined sulphur before being subjected to hydrogenation, e.g. by further treatment in presence of metallic sodium.  In the example, 1 part vulcanized rubber (old motor tyres cut in pieces), 1 part tetraline or white spirit, and 0,1 parts solid caustic soda are placed in an autoclave and the temperature raised slowly to 200 DEG  C. at which it is maintained under a pressure of 200 atmos. for 6 hours.  After cooling, the contents are centrifuged, the solvent is distilled off, and the residual matter treated in a similar autoclave with 5 per cent metallic sodium at 230 DEG  C. for 3 hours under a hydrogen pressure of 200 atmos; re-treatment under the same conditions may be necessary to complete the desulphurization. The product is treated with hydrogen in the presence of 10 per cent copper chromite at 270-300 DEG  C., then diluted with solvent and centrifuged.  A 60 per cent yield of a saturated oil is obtained.
