Title: Improvements in and relating to methods of insulating electrical devices
IPC: H01B3/18
Filed: 1949-11-30
Abstract: 669,158. Coated fabrics; electrical insulating compositions and processes. BRITISH THOMSON-HOUSTON CO., Ltd. Nov. 30, 1949 [Dec. 13, 1948], No. 30741/49. Drawings to Specification. Class 140. An electrical device is impregnated with insulating material by wrapping it with woven material which will permit the passage of fluid only under pressure, treating the wrapped device with a solventless thermosetting liquid insulating material under pressure to impregnate the device, and thereafter releasing the pressure and curing the insulating material. The wrapping may consist of a woven fabric, such as one made of nylon, cellulose acetate, viscose, wool, silk, cotton, glass, asbestos and other fibrous materials, coated with an elastic material, such as high viscosity polyisobutylene, uncured natural, Buna-S or Buna-N (" Buna " being a Registered Trade Mark) rubber, compounded - with tackifiers such as dibutylphthalate, high viscosity alkyd resins, highly plasticized high polymers such as polyvinyl chloride, polyvinyl acetate and their copolymers, polyvinyl formal, polyvinyl butyral, cellulose esters and ethers such as cellulose acetate and ethyl cellulose. The impregnating compositions may comprise (1) a polymerizable alkyd resin, especially one obtained by the partial reaction of ingredients including a polyhydric alcohol and an α-unsaturated, α,#-polycarboxylic acid, e.g. ethylene glycol fumarate or maleate, diethylene glycol itaconate, triethylene glycol maleate, propylene glycol itaconate, glyceryl itaconate, ethylene glycol maleate phthalate, diethylene glycol fumarate sebacate; and (2) a liquid monomer containing an ethylenic linkage that is co-polymerizable with such alkyd resin, e.g. styrene, polyallyl esters of polybasic acids, e.g. inorganic polybasic acids or polycarboxylic acids, for instance diallyl oxalate, malonate, sebacate, maleate, phthalate or itaconate, triallyl aconitate, or phosphate. A small amount of a catalyst for accelerating the thermosetting of the composition, e.g. lauryl peroxide, stearyl peroxide, ascaridol, benzoyl peroxide or acetyl peroxide, is preferably included. Varnishes as described in Specifications 547,328 and 592,400, [both in Group IV], and catalysts as described in the latter may also be used. The electrical device may be wrapped in the coated material in tape form, preferably with the coating on the inside, without leaving any gaps or interstices in the wrapping, and submerged in a bath of fluid impregnant in a pressure tank, the fluid being forced through the tape by applying gas under pressure. After releasing the pressure the impregnated device is removed to an oven to cure the composition, after which the tape may be removed.

Patent GB-434058-A (GB)
Title: Improvements in method of preparing whey concentrates
IPC: A23C21/00
Filed: 1934-10-27
Abstract: Whey is concentrated to give a product having a high vitamin G content by evaporating it at a pH value of not higher than 6 and not below about 5,5.  In an example, phosphoric acid is added to the whey to give the desired pH value prior or subsequent to its introduction into a vacuum pan in which it is then evaporated to a point at which it will set on cooling.  While it is still hot the free phosphoric acid is preferably neutralized by adding lime. After the whey has cooled and set it is subdivided and drying is completed in a drying tunnel at a temperature sufficiently low to avoid carmelization of the sugar, giving a substantially dry, non-hygroscopic product. Where the whey used is a by-product in the manufacture of casein by precipitation with hydrochloric acid, further addition of acid may not be necessary or an excess of acid may be present and may be removed by neutralizing with soda or magnesia or by treating in an electrolytic cell or cells.  The whey used may also have sufficient lactic acid present to give the desired pH value.  The reduction in the pH value reduces foaming p  during concentration of the whey in the vacuum pan.

Alternatively, each light may have its own strip on the drum F. The lights may be cut out by mounting their contacts on a rotatable shaft L that may be turned to lift the contacts from the drum, and, if desired, the shaft may be further turned to make the contacts cut in all the red lights. Individual lights may be cut out by mounting their contacts so as to be angularly adjustable on the shaft L, as shown in Fig. 4, a spring-pressed plunger 1f engaging a tail-piece 1<c> on the contact. The operating and controlling apparatus may be installed in a central refuge P, where it may be regulated by a point policeman.
