Filed: 1955-09-15
Abstract: 784,266. Magnetic amplifiers. BENDIX AVIATION CORPORATION. Sept. 15, 1955 [Sept. 30,1954], No. 26463/55. Class 40 (4). Two single core resetting magnetic amplifiers 30, 31 are connected to form a balanced arrangement giving a differential output, and have common resetting and gating voltages ER and EG which are of the same frequency as the input signal ES. The input signal ES is applied to a primary winding 20 of a transformer 22 and is injected into the resetting circuit of each amplifier by means of a centretapped secondary winding; the injected voltages being in phase or in phase opposition to the voltage ER. During a reset half-cycle the voltage ES increases the firing angle of one amplifier while decreasing that of the other so that in the following half cycle the gating voltage EG produces a differential output. A modulation carried by the input signal ES will be rectified as only alternate half-cycles are used to reset the amplifiers.

Density separators.-Centrifugal apparatus for the separation of solid particles from fluid has a rotating cylinder 2 with radial fins 3 between which flows the fluid to be treated. Between the outer edges of the fins and the casing is placed a number of bodies which offer resistance to the axial movement of the fluid and therefore screen the solid particles thrown out from the flow of the fluid. In the form shown in Fig. 1, the bodies 4 consist of thin rings alternate rings being rotated with the cvlinder 2 while the others are stationary. In a modification, all the rings are attached to the rotating body. In other modifications, the rings form conical surfaces and may be stationary or rotary. In all the forms, a narrow space is left between the outer edges of the rings 4 and the casing 1 to enable the separated particles to drop. Extensions 6, Fig. 9, may hang from the edges of the rings so that the particles drop readily between the extensions.

Title: Novel interpolymers and a process for preparing the same
IPC: C08F279/02
Filed: 1964-06-26
Abstract: Transparent polymeric moulding materials are made by polymerizing methyl methacrylate and a vinyl aromatic compound with 3 to 15%, based on monomer weight, of a linear rubber, e.g. cis-1,4-polybutadiene, linear polycyclopentadiene, linear polyisoprene, linear copolymers of butadiene with styrene, acrylonitrile or isobutylene and linear block copolymers of styrene with butadiene and isoprene.  The vinyl aromatic monomers is preferably styrene, which may be replaced wholly or in part by alpha-methylstyrene, or styrenes substituted in the nucleus by chlorine or alkyl groups.  Also present in the monomer mixture may be 3 to 10% by weight of acrylonitrile.  Polymerization is carried out by dissolving the linear rubber in the monomer mixture, polymerizing the resulting solution to 10 to 45% conversion, then suspending the prepolymer in water and completing the polymerization. Polymerization is initiated by the use of monomer-soluble catalysts, e.g. benzoyl peroxide in the bulk polymerization stage and tert.-butyl perbenzoate in the suspension stage.  The aqueous medium in the suspension stage contains a small quantity of suspending agent, e.g. hydroxyethyl cellulose.

Title: Electrophoretic coating process and apparatus
IPC: C25D13/22
Filed: 1964-06-29
Abstract: Articles are coated by electrophoretic deposition by passing the articles in succession through liquid coating material by means of a power-driven mechanism and causing D.C. to flow through the material and article being coated only when the article is immersed in the liquid to the desired level required for coating. As shown, a tank 11 containing organic coating material which is anodically deposited is connected to the negative earthed side of a D.C. supply. Articles 15, 17 on hangers insulated from the earthed chain-driven conveyer 23 engage bus-bar 33 via brush contacts 29, 31.  The bus-bar has entry and exit segments connected to the supply negative, so that the article enters and leaves the liquid bath at the same (earth) potential as the tank, and insulating members as 36, 38, 42, 44 separating the entry and exit segments and other segments of which segment 41 is shown connected to the supply positive.  Limit switch contacts controlled by trips operated by the brush contacts provide for changeover of polarity of the articles when they are fully immersed in the bath, provision also being made for controlling the length of bus-bar which is held positive depending on the rate of travel of the article through the bath.  Auxiliary cathodes 77 are provided to assist in coating irregularly shaped articles and the bath is stirred by a propeller 73.

A large number of radicals R are specified, especially from the diaminobenzene and 4,41-diaminodiphenyl series but also including diamines of the naphthalene, anthraquinone and heterocyclic series.  The pigments may be employed to colour natural and synthetic resins, in spin-dyeing, coloured pencils and in laminated sheet material.
