Title: Improvements in or relating to dishwashers
IPC: A47L15/06
Filed: 1954-12-14
Abstract: 768,004. Dishwashing machines. AVCO MANUFACTURING CORPORATION. Dec. 14, 1954 [Oct. 22, 1954], No. 36204/54. Class 138(1) [Also in Group XIII] A method of drying dishes in a dishwashing machine having a unitary vat 18, Fig. 1, comprises confining the dishes in the vat thereby providing a space sealed against the entrance of outside air, heating air within the space, circulating the heated air within the space to pick up moisture from the dishes, condensing moisture from the circulated air within the space at a point remote from the dishes and draining the condensed moisture from the space. The machine comprises a cabinet 12 with a top 10, housing the vat 18 for dish racks 46, 48. which vat has a front opening 20 closable by a door 14, hinged along its lower edge. Centrally of the vat sump 36 is an impeller 40 rotatable by a motor 38 and a heating element 42. Mounted in the top of the vat is a pressure relief valve 50, Fig. 3, comprising an annular rubber member 52 having a flanged rim 54 secured in an opening in the vat top and a rubber disc member 56, the members 52, 56 being bonded at intervals near their peripheries. Water is supplied to the bottom of the vat via a solenoid-operated inlet valve, a pipe, a vacuum-breaking air gap and a U-shaped trap pipe, as described with reference to Fig. 2 (not shown) whilst used washing liquid is removed from the sump 36 through a solenoidoperated drain valve 44, Fig. 1. A timed. sequence of washing and rinsing and drying operations is performed in known manner on operation of a timer control 16. During the drying operation the vat is sealed from the outside atmosphere since the relief valve 50, the door 14 and the drain valve 44 are closed and also the water inlet connection is sealed by the U-shaped trap. The air contained in the vat is circulated in the directions shown by the arrows in Fig. 1, and heated by the element 42 so that moisture is removed from the dishes and condensed on the vat side walls, which are not provided with heat insulation. The condensed water runs down the sides and collects in the sump 36 and at the end of the drying cycle the valve 44 is opened to release the water. The valve 50 is provided in order that pressure will not initially build-up in the vat sufficient to blow water out of the trap, the valve members 52, 56 being normally biassed together to maintain a pressure in the vat which must be less than that necessary to force water from the trap.

Title: Emulsified lubricating oil of water-in-oil type
Filed: 1958-11-11
Abstract: An emulsified lubricating oil composition of the water-in-oil type comprises at least 1% of aqueous phase based on the total weight of the composition, the aqueous phase containing 5-20% by weight of calcium hydroxide in the form of particles having a diameter of 0.2-0.5 m .  The lubricating oil may be mineral oil, but blended oils including synthetic hydrocarbon oils and fatty oils may also be used. The emulsified composition may be prepared with the aid of emulsifying agents, which may be anionic (e.g. the polyvalent metal salts of higher fatty acids, resin acids or naphthenic acids, the polyvalent metal salts of the sulphonation products of such acids, the polyvalent metal salts of sulphonic acids derived from hydrocarbon lubricating oils or calcium alkyl sulphonate) or non-ionic (e.g. polyoxyethylene sorbitan esters of the higher fatty acids, especially the mono-, di- or trioleate and the corresponding esters of linoleic or stearic acid) or mixtures thereof.  In the case of alkyl sulphonate emulsifying agents, an alkyl sulphonic acid may be blended with the lubricating oil, or a mineral lubricating oil which contains alkyl sulphonic acids as the result of sulphuric acid refining may be employed, the calcium alkyl sulphonate being produced by reaction with a portion of the calcium hydroxide.  The emulsified lubricating oil composition may also contain emulsion p  stabilizers (e.g. agar-agar, carboxymethyl cellulose or sugar) and lubrication improvers.  In the examples, emulsified lubricating oil compositions are prepared from mineral lubricating oil and calcium hydroxide, the lubricating oil being one that has been treated with sulphuric acid so that calcium alkyl sulphonate is formed in situ.  In some examples additional emulsifying agents (i.e. calcium petroleum sulphonate or a blend of polyoxyethylene sorbitan mono-oleate and sorbitan mono-oleate), agar-agar or cetyl phenol are added.  Specification 781,487 is referred to.

Abstract: 962,010. Zone-melting. CENTRE NATIONALE DE LA RECHERCHE SCIENTIFIQUE. Oct. 10, 1961 [Oct. 14, 1960], No. 36345/61. Heading B1S. In the passage of a molten zone produced by induction heating through a rod held at each end, the width of the molten zone is maintained constant throughout its passage by means for controlling the degree of heating actuated by change in the sum of the temperatures at each end of the rod. In the case of the simultaneous passage of a plurality of molten zones, control of the outer zones only is necessary. The temperature of the ends of the rod and the molten zone may be measured by resistors, thermistors, photoelectric cells or thermocouples. The temperatures may be measured as voltages. The temperature of the molten zone may be measured by a thermocouple placed in an auxiliary solid directly subjected to the induction heating. The temperature of the molten zone may alternatively be produced as a voltage which varies directly as the heating power. As shown in Fig. 4, thermocouples 8, 9 and 10 produce a current in a potentiometer 4 and variation in the voltage effects corresponding variation in the strength of the heating means 3. Other electrical circuits are illustrated in Figs. 6-10 (not shown). Means for effecting variation in the heating means is illustrated in Figs. 11 and 12 (not shown).

Abstract: 1437323 Extruding striped soap PROCTER & GAMBLE Ltd 10 Aug 1973 [11 Aug 1972] 37561/72 Heading B5A A soap or synthetic detergent bar is extruded with a stripe, or stripes, of a distinctive colour or colours, by injection of an aqueous solution or dispersion of the colourant into the soap at a location or locations in a tapering chamber 7, upstream of the outlet from which the soap is extruded. The colourant is injected from one or more injection nozzles 13 which are connected, by a pipe 12 through which the colourant is delivered, to a stainless steel plate 6 at the inlet to the chamber 7 and which comprises either a plurality of openings 16 through which the soap is delivered Figs. 3 and 4 (not shown), or a plurality of radially extending webs, Fig. 5 (not shown). The supply pipe 12 is aligned along the flow lines of the soap, and the upstream end of the nozzle 13 is at a distance "D" from the plate 6 of at least twice the width of imperforate regions of the plate 6, to be out of the region of eddy currents in the soap flowing from the plate 6. The cross-sectional diameter of the nozzle 13 is at least twice that of its supply pipe 12 to generate a high static pressure in the soap passing across the nozzle 13 and thereby prevent upstream flow of the colourant. A spring loaded run-return valve is included in the nozzle 13, which also has a perforated, sintered metal, or mesh outlet 14. The chamber 7 includes a perforated plate or mesh 15 functioning to mix the colourant into the soap. The colourant is delivered to the nozzle by a metering pump, the output of which is automatically related to the extrusion rate and pressure of the soap. The soap with which the colourant is injected may be transparent, white, or a pale non-white colour, and the example relates to a titanium dioxide soap composition into which is injected eight green stripes. By using vanes within the tapering chamber 7, spiralling stripes can be produced. The outer layer of the extruded bar may be removed by skimming. The soap is extruded by a worm 5a, to which it is delivered from a further extruder, via a perforated outlet, at which it is cut by a rotating knife to fall through a vacuum chamber on to the worm 5a. The bar extruding from outlet 8 is cut transversely by a knife.
