Title: Improvements in or relating to circuits in which an oscillator is associated with a reactance tube
IPC: H03C3/14
Filed: 1948-10-08
Abstract: 654,202. Automatic frequency control systems. PHILIPS ELECTRICAL, Ltd. Oct. 8, 1948, No. 26276. Convention date, Oct. 13, 1947. [Class 38 (iv)] [Also in Group XL (c)] In an oscillator having its frequency determining circuit coupled to a thermionic reactance, an additional variable reactance controlled by the D.C. output of the reactance tube is coupled to the frequency determining circuit so as to extend the range of control. As shown, a voltage dependent on the frequency difference between the output of an oscillator 1 and a control oscillation fed to a discriminator 15 is applied to the grid of a valve 17 which is connected as a variable reactance across the tuned circuit 4 of the oscillator 1. The inductance of a cored coil 24, coupled to tuned circuit 4, is controlled by the anode current of the reactance valve 17 flowing through a premagnetizing winding 25. The current variable inductance may be replaced by a voltage variable condenser. The direct-current output of the reactance valve may also be used to control the direction of rotation of a motor-driven condenser in the tuned circuit. The arrangement may be used for frequency modulation.

Title: Improvements in and relating to machines for the towing of clay-ware articles
IPC: B28B11/18
Filed: 1948-10-09
Abstract: 652,965. Polishing clayware articles. WALLEY, J., and JOHNSON, J. A. Oct. 9. 1948, No. 26354. [Class 60] A machine for towing or polishing clayware articles comprises a towing element 43 of a flexible nature in the form of a strip or bar the edge of which is shaped to the contour of the article 16 and having a split centrally of its length, a head to support the article, means for bringing the article and the element into contact and means for creating relative rotation between them. The element is supported on a dovetailed slide from a shaft 20 slidably mounted in brackets 23, 24 and connected by links 26, 30 to a cam which presses the element into contact with the article. The support 15 has cushioning members 17 shaped to facilitate centering of the article and is secured to a shaft 11 rotated continuously or intermittently. The central split divides the element into two parts which flex in opposite directions during the relative rotation. The periphery of the ware is towed by a number of blocks 71 held by strips in dovetailed holders 73 on the ends of levers 61. These elements may not all be of the same shape ; e.g. if four equally spaced elements are used, one diametrically opposed pair may have a groove 75 while the other pair is formed to provide a greater area of contact with the underside of the periphery. The levers 61, which are spring- loaded and pivoted at 62, carry spring- loaded rollers 63 in contact with a cam 47 slidably mounted on the shaft 20 and connected by links 50, 53 with a second cam which may be mounted on the same shaft as the first cam and which is designed to bring the elements 71 into contact with the ware to centre the latter prior to its engagement with the element 43. All of the elements are of rubber or the like provided with an abrasive facing or a material such as flannel which will pickup clay particles and acquire abrasive properties. The machine may be equipped with a conveyer or an intermittently rotated carrier to feed the machine with articles, and, after towing, to carry the articles to a position in which they can be cleaned by air blast and suction. The support 15 may be a vacuum chuck.

Title: Improvements in and relating to casein plastics
IPC: D01F4/00
Filed: 1949-10-24
Abstract: A casein plastic showing improved resistance to water and moisture is obtained by forming a mixture containing casein, melamine and water and/or a water-miscible alcohol, said mixture containing between 2.5 and 25 per cent by weight of melamine (calculated on the weight of the casein) into a mass or article, subjecting the mass or article to a treatment with formaldehyde, drying the thus treated product and heating the dried product. Preferably the forming of the mixture into a mass or article is effected by extrusion.  The term melamine includes mixtures of substances containing melamine, e.g. the mixture obtained by heating melamine which in addition to unchanged melamine includes melon and melan.  The concentration of the formaldehyde bath is usually about 5 to 6 per cent by weight of formaldehyde.  The formalization may be effected in a similar manner to that employed for compositions not containing melamine.  A suitable plasticizer may be added to the initial mixture.  In examples: (1) a mixture of water, finely-melamine, and glycerine, is added slowly to rennet casein in a mixing machine and after mixing until the mass is homogeneous the mixture is allowed to stand and then extruded to form a rod.  The rod is cut into suitable lengths and immersed in a solution of formalin and left for 3 days at 65 DEG F.  The rods are then removed from the bath, dried at 100-120 DEG  F., and then placed in an oven and heated for 16 hours at 158 DEG F.  The rods are then allowed to remain ina humid atmosphere to regain normal moisture content; (2) a mixture of water, glycerine, dyestuffs, titanium dioxide and finely-ground melamine is added to rennet casein as in (1) and the moist mass extruded to yield a rod which is then cut into lengths and treated with formaldehyde solution for 7 days at 65 DEG F.  The rods are then removed from the bath, dried at 100 DEG  to 120 DEG F., and then heated at 210 DEG F. for 16 hours p  and the normal moisture content restored as in (1); (3) the ingredients used in (1) are mixed in the same way but after standing the mixture is worked on a two-roll mill with rolls heated to 60 DEG  to 80 DEG  C. until a homogeneous mass free from unplasticized particles of casein is obtained.  The rough sheet formed on the mill is then removed and pressed into a thin sheet in a steam heated hydraulic press and the sheet is cooled, formalized for a period of about 4 days, dried, and then heated as in (1).
