Title: Improvements in or relating to light-operated controllers
IPC: H01H37/32
Filed: 1923-05-25
Abstract: 198,370. MedÚn, E. H. May 25, 1922, [Convention date]. No Patent granted (Sealing fee not paid). Light and heat radiations, controlling and actuating apparatus by.-The supply of electric current or of gas or other fluid is controlled by the differential expansion of two tubular members under the action of light rays. One member absorbs the light rays and converts them into heat, whilst the second or compensating member is shielded from the rays. The relative movement of expansion is caused to make or break an electric contact, or to open or close a valve, automatically in accordance with variations of light, provision being made to render the apparatus independent of ordinary atmospheric temperature variations. If desired " flashing " apparatus may be combined with the device for the purpose of rendering its action intermittent instead of continuous. The light-absorbing expansion member 30 consists of a tube of copper coated with lamp black mounted within a glass casing 101 surrounded by a wire screen 116. A compensating tube 15 of aluminium is located inside the member 30 so as to be shielded from the light-rays but is connected to it through a short rod 25 which engages with an end plug 28 on the member 30 and also screws into a plug 18 which, in turn, is connected to a rod 20 forced downwards by a spring 24. The lower end of the member 15 rests upon a fixed abutment 10, whilst the member 30 is supported upon a ring-shaped element 40 provided with two diametrical pins 42 which rest upon a Cardan ring 45, supported in turn upon pins 55. Two other supporting pins 46 carried by an annular element 50 are arranged at right-angles to the pins 55. The pins 42 are displaced relatively to the pins 55 and so set up a leverage which is transmitted to the lowest annular member 50, which carries the movable element 65 of the contact to be controlled. The pull of the spring 24 is partly counterbalanced by a spring 60 which is seated in the fixed base plate 7 and presses against the annular member 50. The fixed contact member 80 is adjusted relatively to the movable member 65 by means of a screw fixed in the base plate 6 so that in daylight the contact is maintained open. As daylight fades the part 65 is moved towards and makes contact with the fixed member 80, thereby closing the electric-supply circuit through the leads 70, 85. Fig. 6 shows a modified form of device in which the pivotal movement of the annular member 50 is similarly caused to actuate a spring-pressed valve 142, 140 so as to open or close a passage 134 connnecting a supply pipe 127 with a service pipe 130. The Specification as open to inspection under Sect. 91 (3) (a) comprises also an arrangement in which the tubular member 30 is replaced by two bars or columns of metal connected together at their upper and lower ends, a special screening- member being interposed to shield the compensating member from the impinging light-rays. This subject-matter does not appear in the Specification as accepted.

Filed: 1920-05-20
Abstract: 143,561. Scholz, V., and Tiedemann, C. [Firm of]. May 16, 1918, [Convention date]. Fibrous plastic compositions.-In a process for working up linoleum scrap into new linoleum by treating with organic solvents, only sufficient solvent is used to soften the scrap and enable the jute fibres to be separated by mechanical means from the softened mass of binding cement, ground cork, colouring matter, &c. For example, 1000 k.g. of broken up linoleum scrap are treated with 500 k.g. of alcohol in an autoclave for about 2 hours at a temperature of 80‹-140‹ C., resulting in the reduction of the scrap to a soft crummy pulp. The alcohol is then distilled off, and the pulp is fed on to vibrating sieves to separate the jute fibres from the linoleum pulp. The regenerated substance is finally heated to a temperature of 100‹-120‹ C. to restore the qualities of toughness and glutinousness of the binding cement, which had been depolymerised during the treatment with the solvent.

Title: Improvements in or relating to food products
IPC: A23J3/34
Filed: 1955-05-16
Abstract: An aqueous suspension of a vegetable protein, preferably containing at least 15 per cent by weight of protein, is digested with a proteolytic enzyme, e.g. papain, trypsin, and the digestion is arrested when 10-40 per cent by weight of the protein nitrogen is in a form which is watersoluble at the isoelectric point of the protein. 1 per cent or less enzyme by weight of dry protein is preferably used, together with enzyme activators or inhibitors. Preferred conditions for papain are pH 7 and 60-70 DEG  C.  Oilseed proteins such as soya bean are preferred.ALSO:A food suitable for babies or invalids is prepared by digesting with a proteolytic enzyme, e.g. papain or trypain, an aqueous suspension of precipitated vegetable protein, the digestion being arrested when 10-40 per cent by weight of the protein nitrogen is in a form which is water-soluble at the isoelectric point of the protein.  According to an example steam was introduced into a dispersion of soya bean flakes in 0.003 molar solution of calcium hydroxide until a temperature of 60 DEG C. was reached and the heated suspension was pumped through a basket centrifuge; the clarified extract so obtained was heated to 100 DEG C. and adjusted to pH 5 by 3N hydrochloric acid, and the resulting suspension centrifuged; the cake of precipitated protein, of 31 per cent solids, so obtained was suspended in sufficient water to lower the protein concentration to 16 per cent, and the pH was adjusted to 7 with sodium hydroxide, 0.3 per cent papain, calculated on the dry weight of protein, was added, the suspension was held at 60-70 DEG C. for 30 minutes and was then adjusted to pH 6.5 by addition of hydrochloric acid, 22 per cent of the nitrogen in the protein having been converted at this point to a form soluble at the isoelectric point.  To enhance the nutritive value of the product, there was added a mixture, amounting to 5 per cent by weight of the suspension, of 22 per cent cottonseed oil, 72 per cent soya bean oil and 6 per cent cotton seed oil stearin hydrogenated to an iodine value of 75, the protein concentration being thus decreased to 15 per cent.  The product was made smooth and uniform by milling.  Flavouring agents, colouring agents, vitamins and minerals may be incorporated in the product.  The product may be sealed in cans or jars.
