Title: Improvements in or relating to transmissions, more particularly for motor vehicles
Inventor: FESSLA ANTONIO
IPC: F16H61/14
Filed: 1951-11-09
Abstract: 710,439. Clutches; variable-speed gearing. DUCATI SOC. SCIENTIFICA RADIO BREVETTI DUCATI. Nov. 9, 1951, No. 26365/51. Class 80 (2) [Also in Group XXIX] In a variable-speed transmission the variation in transmission ratio is obtained by a hydraulic converter the driven and driving members 14, 15 of which may be coupled by a clutch 5, 6, in accordance with the speed of the driven member, and a reaction member 16 co-operating with the members 14, 15, is provided with means tending to prevent it from rotating in a direction contrary to that of the driving member. The driving shaft 2 and a driven shaft 3 may be coupled directly by a friction clutch having a casing 4 fixed to the driven shaft 3. Discs 5 are slidably mounted in the casing 4 and the discs 6 are splined to the driving shaft 2. The clutch is actuated by a pressure disc 7 through a sleeve 8. Centrifugal weights 10 carried by the shaft 3 have arms 13 bearing against the end of the sleeve 8. At low speeds the weights 10 bear on the periphery of the sleeve 8 and limit its axial movement in the de-clutching direction. When the centrifugal force on the weights overcomes the resistance of the spring 9 and the oil pressure within the sleeve 8 the clutch is engaged to give a solid drive. A snap engagement is ensured by spring- stressed catches 26, 27. The backward rotational tendency of the reaction member 16 is resisted by a gear pump 18, 19. The pump communicates on one side with an oil sump and on its other side with the inside of the casing 17 of the hydraulic converter and with the chamber 8<SP>1</SP> within the sleeve 8 through ducts 20 ... 25. When the driving member 15 starts to rotate the reaction member 16 tends to rotate backwards and the pump 18, 19 acts to fill the casing 17 and the chamber 8<SP>1</SP>. Rotation of the reaction member 16 in the forward direction will tend to draw oil from the casing 17 and chamber 8<SP>1</SP>. Thus the friction clutch is controlled in accordance with speed and torque. The centrifugal means acting on the sleeve 8 may be replaced by any other mechanical, electrical or hydraulic means which act automatically in accordance with the speed of the driven shaft 3. Manual clutch operating means overriding the automatic control may be provided. A gearbox may be connected to either the driving or driven shafts.

Title: Method of protecting meat and other perishable commodities from deterioration during storage
IPC: A23B4/10
Filed: 1932-09-26
Abstract: Beef, mutton, lamb, pork, fish, poultry, and other perishable commodities are preserved by coating with a protective film of a hydrogenated animal fat or vegetable oil or a mixture of the fats and oils which hardens or sets at ordinary temperatures, e.g. by dipping in or spraying with the molten oil or fat.  In a modification, paper or fabric is impregnated with the oil or fat and applied to the commodity before the oil or fat has set.  The following may after hydrogenation treatment be employed for the coating, artificial lard compounds, shortenings, beef, mutton or lamb fats, lard, whale oil, stearine, or peanut, cotton, coconut, sesame, soya or sheanut oils. A small amount of edible paraffin or glycerine or both may be added to give smoothness to the hardened film.  The commodity may be placed in a container which is then evacuated and the coating medium added by flooding, followed by removal of the excess of medium or by spraying and cold air admitted to harden the film.  An inert gas, such as carbon dioxide, under pressure, may be introduced into the container after evacuation and prior to adding the coating medium, or the evacuation may be omitted and the air in the container displaced by the inert gas.  Two containers may be used, one for the preliminary treatment and the other below it containing the coating medium into which the commodities suspended or carried in cages are lowered through an opening between the containers.  The coating may be applied to commodities to be stored in inert gas or to be frozen or chilled, or may be applied after freezing.

Title: Improvements in or relating to the continuous heat treatment of moving elongate ferrous material
Inventor: JENKINS WALTER NORMAN
IPC: C21D9/56
Filed: 1962-07-12
Abstract: Elongated ferrous material is heat treated by passing it through a liquid heat transfer medium, and heating it by induction between its entry to and final exit from the bath, the temperature characteristic to which the material is subjected being controlled in accordance with the hardness of the treated strip to maintain the latter uniform. In one embodiment Fig. 1 (not shown) the strip is preheated in a liquid bath, passed out of the latter and through an induction heater, and returned to a liquid quench bath, the liquid being circulated between the quench and preheat baths in closed cycle.  In another embodiment, Fig. 2 (not shown) the material remains in a circulating liquid bath throughout the heat treatment and is heated by induction while passing therethrough.  The hardness of the strip may be detected by magnetizing to saturation followed by magnetizing in the opposite sense, the coercive force or remanent magnetism giving a measure of hardness.  The heat treatment may be carried out in an oxygen-free atmosphere containing a predetermined amount of water vapour whereby the strip is slightly oxydized and dragout losses from the metal bath are reduced.

Abstract: 798,080. Imitation gems. SIMILI FABRIK FEINER SCHLEIFPRODUKTE ANSTALT. Sept. 20, 1955 [Sept. 29, 1954], No. 26872/55. Class 43 An imitation gem of glass, transparent plastics or the like has the rear portion 5, which is adapted to be located within a setting 17, provided with a continuous coating 6 of a material which reflects a portion of the light that is incident upon it and allows the remaining, preferably smaller, portion to be transmitted through it. In the example the gem is formed with a front face 2, facets 3, peripheral edge 4, and a facetted pointed lower part 5 which is coated with a semi-transparent layer of silver 6. Part of a light ray 7 which impinges on a facet of the lower part 5 is reflected along the lines 10, 13 and 16, whilst part is transmitted through the coating in the directions 11 and 14 and, upon casual examination, gives the effect of a genuine stone. Preferably the coating consists of a thin, highly reflecting layer of a metal such as silver, chromium, rhodium, or a metal compound such as an oxide, sulphide or fluoride, deposited for example by evaporation in a high vacuum, by cathode sputtering or by a chemical or physical centrifugal process. The coating may comprise a succession of several thin layers of the material, the optical thickness of the individual layers preferably being equal to one-quarter of the wavelength of the incident light or a multiple thereof. A transparent protective layer, e.g. of silicon dioxide is preferably applied over the semi-transparent coating material, the thickness of such protective layer preferably being equal to, or a multiple of, half the wavelength of the incident light. The setting 17, which holds the gem above the peripheral edge 4, is open at its lower portion 18, so that the light rays 11 or 14 are received by a viewer looking at the gem from below.
