Title: Manufacture of cheese
IPC: A23C19/068
Filed: 1955-01-31
Abstract: In the manufacture of Swiss type cheese, the curd is subjected to vacuum before it has lost its ability to knit together and before it has become firmly knit, preferably after shaping.  The vacuum, which is applied for sufficient time to remove a substantial portion of occluded gases, is preferably at least equivalent to 20 inches of mercury e.g. 25-27 inches and mechanical pressure, preferably 0,2-0,65 lbs/sq. inch may be applied to settle the curd into a compact mass.  The vacuum may be applied stepwise.  The treatment is preferably carried out promptly after separating out the whey, which may be by mechanical agitation.  Examples of Swiss type cheese manufacture are described in the Specification.  Specification 715,500 and U.S.A. Specifications 2,494,636 and 2,494,637 are referred to.

Filed: 1970-01-21
Abstract: 1292216 Rolling lined cylinders and rings F D TIMMERMANS 21 Jan 1970 2823/70 Addition to 1262160 Headings B3A and B3M A method of rolling a cylinder of one metal 13 internally lined with a softer metal 12 comprises rolling it between internal and external rolls 15, 14 respectively to stretch the internal layer to such an extent that when the rolled cylinder is cut longitudinally it opens out to a substantially flat configuration. The roll pressure on the inner surface is smaller than that on the outer and this is achieved by making the diameter of the roll 15 larger than that of the roll 14. The cylinder, which is of steel lined with lead-bronze, is heated to 500-600‹ C. and the roll 15 is maintained at a lower temperature than the roll 14 by water or oil cooling. The lined cylinders may be transported in pairs by electromagnetic grabs on to a pair of inner rolls and after rolling, the pair of cylinders are placed by the grabs on to a conveyer belt. The rolled cylinders are cut along any weld that may be present and the sheet obtained may be used, either with or without further hot rolling, to make bearing shells as described in parent Specification.

Abstract: 556,154. Electrostatic separators. ROSIN INDUSTRIAL RESEARCH CO., Ltd., DR., and DEUTSCH, W. March 17, 1942, No. 3533. [Class 72] In an electrostatic separator the material to be tested passes through a corona field formed by a corona electrode and a counter-electrode opposite to it, in which it is first electrically charged in a suspended state and then through a coronaless field formed by two -electrodes which do not ionize the air between them in a suspended state in the surrounding air and in which the separation takes place. The mixture may be allowed to fall freely under the action of gravity through the coronaless field or may be thrown upwards continuously on a member along which it is conveyed, by subjecting the member to continuous up and down transversal oscillations. The material a is fed from a hopper b and falls through a corona field produced between the wire d and a counter electrode e surrounding the latter. The wire d is connected to the hopper b and to a central rod electrode f surrounded by a number of concentrically superposed annular receptacles g<SP>1</SP>, g<SP>2</SP>, g<SP>3</SP>. between the inner surface h of which and the rod f, the coronaless field i is formed. The receptacles g' &c. are insulated from, and support, the corona field preferably by insulators j, being themselves supported on, and insulated from. an earthed base k by insulators. The receptacles g<SP>1</SP> &c. are connected by insulating supports g and the rod f is secured to the base k on a receptacle m. Annular openings n are left at the top of the inner surfaces h of the receptacles g' &c. for the reception of separate components of the mixture, the last component separated being received in the receptacle m. The hopper b, electrode d, the rod electrode f and the receptacle m are all earthed through the base k and a high tension current is applied both to the electrode e and the receptacles g<SP>1</SP>, g<SP>2</SP>, g<SP>3</SP> which form one electrode of the field i. The receptacles g<SP>1</SP>, g<SP>2</SP>, g<SP>3</SP> are each provided with a hinged door o for the removal of the material collected therein. In another form, the material is fed by a hopper into an open-ended trough and then on to a vibrating plate, the corona field being formed between the trough and a pointed electrode above it. The material then passes into the coronaless field formed between the metal plates arranged over the vibrating plate and then into a receptacle provided with a number of compartments and arranged under the latter plate. An endless belt, the surface of which is oscillated up and down, may be substituted for the vibrating plate.

Abstract: 303,292. Heyl, G. E., and Hycolite Liquid Wallpaper Manufacturing Co., Ltd. Feb. 7, 1928. Single coatings; compound fabrics. - In the manufacture of linoleum, finely disintegrated dry oil-resistant paper or fibrous pulp such as wood pulp is used in place of cork, together with a mineral lubricant such as china clay or plaster of paris. The paper is rendered oil-resistant by being soaked in varnish or in a drying oil such as oxidized linseed or kapok oil and dried prior to final disintegration. The paper or pulp may be soaked in the varnish or oil prior to disintegration, paper for instance being dipped as sheets and hung up to dry, or the paper or pulp may be drenched with oil or varnish after disintegration, and the resulting cake of material finely disintegrated after drying. Disintegration may be effected in a high speed impact beater for acting on dry materials. The proportions may be 60 to 50 per cent of paper or pulp and 40 to 50 per cent of mineral lubricant. The linoleum mixture and the process of manufacture are as usual, the mixture consisting for instance of cork, paper or fibrous pulp, mineral lubricant and a drying oil, with colouring matter, but the proportion of cork is reduced from 10 to one per cent.
