Title: Improvements in or relating to the manufacture of synthetic resins and compositions containing the same
IPC: C08G8/28
Filed: 1936-12-17
Abstract: Oil-soluble heat-hardening resins are produced from phenols by reacting with an aldehyde in the presence of a mild acid catalyst in the presence of a completely volatile non-gumforming solvent selected from the class of monohydric aliphatic alcohols and mononuclear aromatic hydrocarbons.  Suitable catalysts include zinc or copper acetate or boric acid.  Suitable solvents include di-isopropyl carbinol, iso-propyl carbinol, iso-butyl carbinol, amyl carbinol, iso-amylcarbinol, toluene, benzene and xylene. The resin solutions obtained may be combined with drying oils, semi-drying oils, cellulose derivatives (ethylcellulose, nitrocellulose or benzylcellulose), natural or synthetic resins such as rosin, kauri, vinyl resins, other phenol-aldehyde resins, acrylic or methacrylic acid ester polymers, oil-modified polyhydric alcohol - polybasic acid resins, hydrogenated natural and synthetic resins, hydrogenated phenol-aldehyde resins, hydrogenated rosin, hydrogenated rosin-modified phenol-aldehyde resins, hydrogenated ester gums, pigments, fillers, driers or solvents.  The products may be used in the manufacture of coating, impregnating, sizing, moulding and adhesive compositions.  In examples: (1) phenol and paraformaldehyde are condensed in the presence of ethyl alcohol, butyl alcohol, diethyl carbinol 2 - methylpentanol - 1, 2.4 - dimethylpentanol 3 and di iso-propylcarbinol as solvents and zinc acetate or boric acid as catalyst, the product being worked up if desired with chinawood or castor oil to yield coating compositions; (8) o-cresol, paraformaldehyde, di-iso propylcarbinol and zinc acetate are condensed.

Title: Improvements in or relating to frequency changing apparatus
IPC: H03C1/52
Filed: 1936-12-18
Abstract: 484,017. Modulating and frequencychanging apparatus. GENERAL ELECTRIC CO., Ltd., and GEORGE, E. P. Dec. 18, 1936, No. 34840. [Class 40 (v)] In frequency-changing apparatus of the type comprising one or more non-linear impedances, the impedances consist of the discharge paths of gas-filled thermionic valves, which approximate closer to ideal non-linear resistances than do diodes or dry rectifiers. When the non- linear impedances are ideal the only products of modulation are of the form pf2Œf1, where p is zero, or any odd integer. In the circuit shown, the gas-filled valves G1, G2, are included in a normal push-pull circuit, the signal being applied to terminals 4 and 5, the carrier to terminals 6 and 7, and the wanted products of modulation with the carrier frequency suppressed are taken from terminals 8 and 9, through filter L. The control grids 1, 2, are adjustably biassed by battery 11 and potentiometer 10, so that the striking voltage of each valve may be independently controlled. A battery B2 maintains the anode potentials at such a value that the valves strike and conduct immediately the carrier voltage is positive. British Specification 218,335, [Class 40 (v)], and U.S.A. Specification 1,999,686 are referred to.

Abstract: 454,743. Walls; bricks. SODDY, F., 131, Banbury Road, Oxford. Dec. 16, 1935, No. 34910. [Classes 20 (i), 20 (iv), and 87 (i)] The vertical columns or pillars between the window openings of a building are of rhomblike or trapezoidal form in horizontal crosssection, one or both pairs of opposite sides being parallel and two diagonally-opposite angles being obtuse. The pillars E shown in Fig. 3 have both pairs of opposite sides parallel, and those in Fig. 4 have only one pair of opposite sides parallel. The pillars may be arranged, as shown in Figs. 3 and 4, so that the window spaces are alternately splayed from within outwards and from without inwards, thereby forming alternately external and internal embrasures. The pillars may be built up of standard trapezoidal bricks G, the angles of which are respectively 45, 135, 67¢, and 112¢ degrees. Such bricks may be arranged to form pillars as shown in Figs: 6 and 7, or they may be subdivided and built up with ordinary rectangular bricks K as shown in Fig. 9. The interior rectangular bricks K shown in Fig. 9 may be replaced by reinforced concrete. The pillars may be arranged to constitute the external walls of a chemical laboratory as shown in Figs. 12 ,and 13, the benches Q being aligned with the outwardly-splayed windows P which are continued in vertical lines across one or more floors. The window openings P may be glazed with single panes, preferably co-planar with the inner wall face, and the alternate windows N may be co-planar with the outer wall face. Pillars at wall corners and other bends in a wall may be formed solely of bricks of the standard trapezoidal cross-section.

Abstract: 283,151. Miller, W. J. Jan. 5, 1927, [Convention date]. stream-cutting machines; extrusion machines; flower-pot and like machines; presses.-A machine for the manufacture of pottery comprises means for extruding plastic material in or on to moulds, means for severing charges of material, means for shaping the charges and jiggering means. As shown, the moulds A, supported in trunnioned trays 96 carried by endless chains, are brought in turn beneath a container 5 for the plastic material then under a shaping plunger 41 and finally under a profile 77. The material is extruded from the container 5 through an orifice 11 and is severed by a wire or blade 53. A feed shaft 13 within the container is driven intermittingly from a shaft 59 through a cam 65 lever 62 ratchet gear 28, 26 and bevel gears 20, 19; a slight return movement is imparted to the shaft at the end of such operation by a spring- controlled brake band 29. The plunger 41 is surrounded by a loose sleeve 44 adapted to embrace the mould and held down by a spring 45. A cam 24 depresses the plunger against the action of a spring 48. The plunger is furnished with a chamber 42 adapted to contain lubricant or to receive heating or cooling fluid. The profile 77 and associated cutter 80 are depressed into operative position by a spring and are disengaged by a rod 93 operated from a shaft 112 through a cam 111 and lever 110; the rod 93 also raises the moulds into operative position through members 105 adapted to engage reduced portions of the mould spindles 101. Rotary movement may be imparted to the spindles 101 from a motor 103. The shaft 59 is driven from the shaft 112 through a belt. The cutter 53 is carried by a lever 56 rocked by a cam 69 on the shaft 59. A cam 113 on the shaft 112 advances the mould trays through a lever 117 and finger 121 adapted to engage the trunnions 97. Fig. 4 shows a modification in which the extrusion orifice 10<a> is furnished with a sleeve 131 adapted to be rotated through a ratchet bar 134 connected to lever 56, a cutter 133 being secured to the lower end of the sleeve. Fig. 7 shows an orifice furnished with. a chamber 10<c> through which heating or cooling fluid may be circulated by connections 10<d>; or the chamber may receive lubricant, which is extended through apertures on to the plastic material.

Near the ends 6, 7 of the lower leaf 1 interleaving packs 13, Fig. 4, of rubber or plastic are inserted, and retained by a peg 14 projecting into a hole 15 in the lower leaf. If the thickness of the upper leaf at the eyes 11, 12 is sufficient for the eye, the taper may continue to the end of the leaf. Alternatively the tapered portion 9 may be followedby a thicker portion of uniform thickness to provide more material for the eye. A further alternative is for the taper to be followed by a portion of uniform thickness the thickness being that of the smallest portion of the taper. The lower leaf may be tapered in width as well as in thickness.

An annular electrical component, e.g. a transductor core, is sealed by toroidally winding on it, with overlap, a thin tape of unsintered perhalocarbon polymer, and thereafter sintering the polymer. The core of a transductor consists of iron tape 14, e.g. of super mu metal wound spirally in a groove 12 in the periphery of a ceramic former 10. An aluminium ring 16 may be press fitted over the former. To prevent seepage of impregnant from the winding into the iron core, with resultant changes of permeability, the former is covered with a single toroidal winding of thin tape of unsintered perfluorocarbon polymer, having at least 65% overlap between adjacent turns. The assembly is heated at 350-370‹ C. to sinter the tape, which shrinks to a largely homogeneous covering about two thicknesses deep. Suitable polymers are polytetrafluoroethylene and polytrifluorochloroethylene. U.S.A. Specification 2,685,707 is referred to.
