Title: Improvements in dishwashing machines
IPC: A47L15/06
Filed: 1960-06-28
Abstract: 876,839. Dish-washing machines. GENERAL MOTORS CORPORATION. June 28, 1960 [July 27, 1959], No. 22606/60. Class 138(1). [Also in Group XXV] A dish-washing machine comprises an apertured spray tube 30, Fig. 1, rotated by a reversible electric motor 42 which also drives an impeller 152, Fig. 11, within a sump housing 136, the impeller when rotated in one direction pumping liquid to the spray tube 30, and when rotated in the opposite direction pumping liquid to a drain 168 and also functioning as a waste communicating device, a valve 174, 178 being provided which in one position prevents flow to the drain 168 and in another position prevents flow to the spray tube 30. Before the dishes are placed in the machine the strainer 126 above the sump is raised and retained in an upper position by spring tabs 132 on the tube 30, whilst waste is scraped from the dishes into the sump, and the strainer is again lowered. The machine is then operated under the control of an electrical timing mechanism 200 which first opens a solenoid valve 216 to admit water into the washing chamber through a pipe 218, and energizes the motor 42 to rotate the impeller 152 in a direction such that it co-operates with the edges of the apertures 150 in a shoulder ring 144 to function as a waste communicating device. In this direction of rotation the spray tube 30 raises, through a nut 190 secured thereto, a screw 182 which is restrained from rotation and carries the valve members 174, 178. The member 174 is thus raised to close the inlet-end of the spray tube 30, and the member 178 is lifted to allow the liquid containing the comminuted waste to pass to the drain 168. After a predetermined period the timing device 200 reverses the rotation of the motor 42 and of the spray tube 30 to lower the valve members 174, 178, thus closing the entrance to the drain 168, whilst the valve 216 remains open for a time sufficient for the supply of the required amount of washing liquid, to which detergent may be dispensed by an automatic device during said time. After closure of the valve 216 the motor 42 continues to rotate the impeller 152 to circulate the washing liquid through the rotating spray tube 30, the filter 126, and the sump housing 136. The washing cycle is terminated when the motor 42 is again reversed to raise the valve member 178 to allow the washing liquid to pass to the drain 168. A rinsing cycle may then be initiated, followed by a drying operation effected by an electric heater (not shown) within the washing chamber. Arrangements for hingeing the doors of the cabinet of the machine are described (see Group XXV).
Patent GB-373490-A (GB)
Title: Improvements relating to the manufacture of coumarin
IPC: C07D311/10
Filed: 1931-08-11
Abstract: Crude coumarin is purified by forming an addition product of coumarin with a sulphite or bisulphite, separating the impurities from the addition product, and then decomposing the product.  The reaction of coumarin with a sulphite or bisulphite yields a water-soluble non-volatile product, the aqueous solution of which can be boiled, distilled with steam or under reduced pressure, or extracted with organic solvents, without decomposition.  The addition product is decomposed by heating with strong mineral acids.  In an example, crude coumarin is heated with an aqueous solution of sodium bisulphite, and the solution is filtered and boiled, whereby insoluble and volatile impurities are removed; further purification is then effected by steam distillation, and the solution is cooled, treated with concentrated sulphuric acid, and reheated, whereby the coumarin is liberated.  The process may be effected by passing sulphur dioxide into an alkaline solution containing the crude coumarin.

Title: Improvements in ball and float supply valves for water-waste preventers
IPC: F16K31/26
Filed: 1938-08-02
Abstract: 517,634. Ball-and-float valves. PALSSON, B. Aug. 2, 1938, No. 22869. [Class 135] A cistern supply valve particularly adapted for use in water waste preventers is arranged so that the final closing movement of the valve is independent of the float. A hinged float 17, 18, 19 acts with lost motion directly on a lift valve member 7 closing against the flow and overbalanced against inlet pressure by a piston 15. This piston which is slightly larger in diameter than the inlet passage works in a cylinder 14 connected to the inlet by an axial passage in the valve member and piston. A still larger piston may be employed, in which case some. form of braking device such as a roll packing is fitted. The valve casing may also house a loose ball valve normally held to its seat by water pressure but adapted to open and admit atmosphere should suction occur in the inlet conduit. To avoid shocks an air chamber may be fitted to the cylinder 14 or the cylinder may be extended and an additional spring-loaded piston fitted.

Patent GB-736673-A (GB)
Title: Process for the manufacture of artificial sausage casings from animal fibrous material
IPC: C08L89/00
Filed: 1950-09-19
Abstract: In the manufacture of artificial sausage casings from fibrous animal material such as skin or muscle tissue by comminuting the material to form a paste or dough and extruding this through annular nozzles, the comminution is carried out while the material is still fresh and has undergone no chemical changes since the slaughter of the animal from which it was obtained, and the material is not treated with any chemicals effecting a degradation of the protein substances of the material before comminution. The material may be kept fresh between slaughter and comminution by refrigeration or storage in vacuum or in an atmosphere not containing oxygen.  The material may in addition be subjected to a very moderate degree of drying which does not chemically change the proteins present.  The material may be moistened with a little water before comminution, and water may also be added after comminution.  Instead of water, glue liquor, liquid extracts from fresh skin material, or liquid containing elastins, keratins or other protein substances in an unmodified form may be added.  The comminuted mass may be additionally homogenized before extrusion, and tanning or softening agents, such as glycerine or tricresyl phosphate, may then be incorporated in the mass.  The elasticity of the comminuted mass may be adjusted by the addition of chemical swelling agents, the pH value of the mixture indicating its elasticity.  A mass having a pH value of 2-5, preferably 3.5, and a dry weight content of 8-10 per cent is particularly suitable for producing extremely thin sausage casings.  The elasticity of the paste may be adjusted by mixing the slaughter-fresh material before comminution with old material which has been swollen by chemical agents.  Alternatively the old and fresh materials may be comminuted separately before mixing them.  The extrusion apparatus need not be equipped with devices for orientating the fibres in several directions.

Title: Apparatus for indicating or controlling the level of liquids
Inventor: MEJEAN JACQUES G
IPC: G01F23/60
Filed: 1957-07-23
Abstract: 818,906. Indicating liquid levels. AEROTEC CORPORATION. July 23, 1957, No. 23340/57. Class 123(1) [Also in Group XXXVII]. A device for indicating a high or low level of liquid in a container, for example, fuel in the tank of an aircraft, which is unaffected by surging or the presence of foam, consists of a float 16 carrying a rod 18 having a ball contact 19 and sliding within a cylinder 15 having apertures 17 for liquid flow. The cylinder 15 is, mounted in a: porous metal cup 14 having walls of about 1/16 in. thickness and formed of mesh or preferably of sintered spherical particles of metal, for example; stainless steel, brass or bronze. The rimof the cup: is welded to a ring 13 which is screwed into an upper cylindrical part 10. A pairs of contacts 24, 25 are mounted in insulating material 26 in the part 10 and have opposing faces spaced apart so that they are bridged by the ball 19 as the float is. lifted by the liquid on reaching its maximum permitted level. The ball 19 closes an electric circuit of an indicator or high level alarm. To use the device to give a warning of a low level it is fitted at that level in the inverted position or the circuit is arranged so that the warning is given when the ball 19 leaves the contacts. The porosity of the cup walls is chosen so that liquid can flow therethrough, with sufficient rapidity to establish a level in the cup corresponding to the true or average level in the tank whilst preventing, sudden entrance or exit of liquid due to surging. Suitability the porosity is such that particles of sizes down to 0.002 ins. are filtered out. Spray, foam or solid particles cannot enter the cup, whilst flame from an explosion therewithin due to sparking at the contacts is prevented from passing into the tank. In a modification, an additional pair of contacts is provided on the float switch which are bridged by the ball whilst the float is in its lowermost position to complete a circuit (see Group XXXVII) through a solenoid to hold the moving contact of an alarm relay actuated when the upper contacts are bridged against displacement by vibration.
