Abstract: 1,205,706. Hot water supply systems. SOC. GENERALE DE FONDERIE. 5 April, 1968 [14 April, 1967], No. 16397/68. Heading F4A. [Also in Division F2] An instantaneous water heating coil S supplying a hot water system 2 is in parallel with a water storage tank B through which water from the coil 5 is circulated by means of a pump 61 at least when water is not being drawn off. The coil 5 is heated by water in the chamber 4 of a central heating boiler 3. A thermostatically controlled valve R may be provided in the pipe connection 16 between the tank B and the system 2. The connections c and f of the valve R are connected to the tank B, and the pipe 63 to connection c is of reduced cross-section. The thermosensitive cell 91 controls the position of the valve member 73 relative to the sleeve 71 and therefore the flow to the connection m through the valve orifices Oc and Of. With water being drawn off from the system 2 and with hot water in the tank B, hot water from the tank flows through the orifice Of and the connection m to the system 2. When cold water starts to flow from the tank B the cell 91 operates the valve member 73 to open the orifice Oc and a reduced flow of water is supplied to the system through the pipe 63 and the valve R. A non-return valve may be provided in the pipe 63 to prevent flow to the system 2 through the valve R.

Abstract: 264,122. Holfert, M. W. Jan. 9, 1926, [Convention date]. Three-colour and like apparatus.- In a process for reproducing a coloured design or pattern, and determining the best correct colours therefor, black and white drawings representing each of the coloured parts of an original design, Fig. 1, are made by hand on paper or cardboard. Figs. 2 and 3, for example, represent the parts a, b. From these black and white drawings, negative transparencies are made and projected on to a screen in superimposition the colour or luminosity used for projection being varied to ascertain the correct or best colours. Specifications 206,037 and 227,072 are referred to. In the Specification as open to inspection under Sect. 91 (3) (a) alternative processes were included as follows. Where a particular colour is specified for the groundwork or any other part or parts of the design, a sketch is made, Fig. 2 (Cancelled), in which that portion for which a colour is prescribed (e.g. say the groundwork a), is white, and a duplicate is also made, Fig. 2, in which the groundwork m is black and the remainder white. A three-section (colour-filter) -photograph is made of Fig. 2 (Cancelled), three partial negatives made from this, and three colour printing blocks made from these negatives. A printing block is also made from Fig. 2. The sketch of Fig. 2 (Cancelled) can thereby be produced in various colours and with any prescribed or desired groundwork a. If more than one component part of the original sketch, Fig. 1, is to be in a prescribed or varied colour, e.g. parts a and b, separate black and white reproductions, Figs. 2 and 3 (Cancelled) are made for these parts and a sketch, Fig. 4 (Cancelled), of the remainder, sets of printing blocks being similarly produced and used. Separate black and white copies of all the parts a, b, c<1>, c<11>, d, e may be similarly made if desired or necessary. Alternatively to printing from printing blocks, separate diapositives may be produced of any part or parts of the complete pattern for which a colour is prescribed, or a variation of colour is desired and in which diapositives the outside area is completely opaque. Colour component diapositives are also made of the remainder of the pattern. The recomposition of the complete design is obtained by additive projection through selected filters or by means of a chromoscope. This subject-matter does not appear in the Specification as accepted.

Title: Improvements relating to the heating or cooling of canned foodstuffs ready for use
IPC: A47J36/28
Filed: 1940-11-18
Abstract: 546,118. Heating or cooling canned foodstuffs. ELLIS, S. S. C., and GLAZEBROOK, C. Nov. 18, 1940, Nos. 16624/40 and 14780/41. [Class 64 (ii)] A can containing foodstuffs is soldered in an opening in a sheet which constitutes the closure of an outer vessel, so that it is almost surrounded by the latter. The outer vessel contains a chemical to which water can be added after puncturing the vessel, thereby generating heat by chemical action to heat the foodstuff. In a modification the closure and can are removable so that the outer vessel can be recharged and used again. In Fig. 2, the outer vessel 17 is used as the food receptacle and the chemical container 18 is soldered to the closure member 19. A perforated tube 20 extends through the container 18, to which water is admitted after perforating at 21. The perforated tube distributes the water to the chemical. Radial struts or vanes 22 may be provided to centralise the tube 20. In a modification, Fig. 4, the chemical container 24 may be oval or flat to increase its heating surface, or in another alternative, the container may have external radial ribs for the same purpose. In another modification, the chemical container may be provided with a separate dished lid which forms a measure for the water to be added. The lids for both the food and chemical containers may be screwed on, with packing, and may be at the same or opposite ends of the device. Alternatively, lever lids may be used The chemical container 36, Fig. 10, may be made as a separate unit applicable to a food can or a cooking pot. The container is pointed at 37 so that it may be used to pierce a food can. The chemical may in all cases be chosen so that, on addition of a liquid, it absorbs heat and cools the foodstuff. Reference has been directed by the Comptroller to Specifications 13716/98, 9853/04, 16822/04, [all in Class 64], and 17713/07, [Class 28].

Patent GB-495887-A (GB)
Title: Improvements relating to the production of alcohols of the cyclopentanopolyhydrophenanthrene series
Filed: 1937-06-17
Abstract: Trans-alcohols of the cyclopentanopolyhydrophenanthrene series are converted into compounds which are their isomers in respect of the steric position of the hydroxyl group, by saponifying a sulphonic acid ester of the alcohol, if desired after previous re-esterification.  Parent materials for the process of the invention mentioned include the sulphonic acid esters of sterols, and in particular cholestanols and coprosterol; androsterones, androstanediols, androstane-17-ol-3 ones, hexahydro-oestradiols, oxy - bisnorcholanic acids, oxy - aetiocholanic acids, pregnanolones, and pregnanediols.  The sulphonic acid esters may be conveniently prepared by the action of a sulphonic acid halide on the hydroxy compound or by the action of a sulphonic acid salt on a halide of the cyclopentanopolyhydrophenanthrene series.  The saponification is preferably conducted by prolonged heating with alkali hydroxide in aqueous or alcoholic solution.  In cases where re-esterification is used, it is preferred to heat the sulphonic acid ester with an organic carboxylic acid in glacial acetic acid solution, and then saponify the ester so produced.  In examples: (1) cholestanol-para-toluene sulphonic acid is saponified with alcoholic caustic soda to give epi-cholestanol.  The methane sulphonic ester may be substituted for the p-toluene sulphonic ester; (2) cholestanol-p-toluene sulphonic acid ester is saponified with N-sulphuric acid to give epi-cholestanol; (3) a glacial acetic acid solution of cholestanol-p-toluene sulphonic acid ester is heated for 10 hours in the presence of sulphuric acid, and the sulphur-free product saponified with alcoholic caustic soda to give epi-cholestanol; (4) a glacial acetic acid solution of cholestanol methane sulphonic acid ester is heated with potassium acetate for 60 hours and the sulphur free product saponified with alcoholic caustic soda to give epi-cholestanol; (5) transandrosterone-p-toluene sulphonic acid ester is heated in glacial acetic acid solution with potassium acetate for 4 hours, and the cisandrosterone acetate so produced is saponified with alkali to give cis-androsterone.
