Patent GB-633093-A (GB)
Title: Improvements in the production of dull lacquer finishes
IPC: C09D101/18
Filed: 1947-02-06
Abstract: Dull lacquers are prepared by incorporating an alcohol-soluble or aqueous alcohol-soluble polyvinyl resin in a solution of nitrocellulose containing alcohol to form an homogeneous solution and adding a precipitating agent for the nitrocellulose to produce a dispersion of discrete particles of nitrocellulose.  The polyvinyl resin may be a modified polyvinyl alcohol such as polyvinyl butyral. The nitrocellulose may be alcohol-soluble or alcohol-insoluble, but it should have a nitrogen content (as N2) of 12.3 per cent or less. The lacquer may be prepared by mixing solutions of polyvinyl butyral and nitrocellulose, or by adding dry polyvinyl butyral to a solution of nitrocellulose, followed by a suitable solvent.  In the former method the nitrocellulose solution should not contain more than 35 per cent, and in the latter less than 20 per cent.  The concentration of polyvinyl butyral should be not less than 10 per cent.  The precipitating agent may be alcohol or aqueous-alcohol.  In an example (all parts by weight), a solution of 25 parts alcohol-insoluble nitrocellulose is prepared in 25 parts acetone and 50 parts industrial spirit.  A second solution of 25 parts polyvinyl butyral in 75 parts industrial spirit is prepared.  100 Parts of the first solution are mixed with 120 parts of the second solution and substantially 100 parts industrial spirit added to precipitate the nitrocellulose.  Softeners (5-50 per cent of the weight of polyvinyl butyral) such as castor oil, tricresylphosphate, dibutyl phthalate and ethylene glycol butyl ether phthalate may be added if desired.

Title: Improvements in or relating to the generation of short electric pulses
IPC: H03K5/07
Filed: 1940-02-27
Abstract: 580,801. Impulse generators. STANDARD TELEPHONES & CABLES, Ltd., and BEATTY, W. A. Feb. 27, 1940, No. 3621. Drawings to Specification. [Class 40 (v)] A train of impulses of short duration compared with their spacing and occurring within small limits, at fixed time instants, is obtained by generating a succession of damped trains of high frequency oscillations and separating out a peak of each train by amplitude filtering. The damped trains may be generated by using a continuous wave to shock excite a tuned circuit or trigger a valve oscillator as described in Specification 579,126. The duration of the impulses is determined by the high frequency which may be 1 m.c. and the pulse frequency by the continuous wave which may be 15 k.c. If each damped train commences with, say, a positive half-cycle, a train of positive impulses is produced, but the trains may commence with positive and negative half-cycles alternately to produce an alternating train of impulses.

Abstract: 1504741 Ionization detectors RADIOCHEMICAL CENTRE Ltd 21 Jan 1976 [28 Jan 1975] 3742/75 Heading G1N [Also in Division H1] An ionization detector, e.g. an electron capture detector for gas analysis, comprises two electrodes across a gas passage and a radio-active source of Fe 5   5  emitting electrons to ionize the gas. Auger electrons of approx. 5À5 KeV from Fe 5  5 will produce the same ion current as a weaker conventional Ni 63  beta source (67keV) but the more numerous electrons give improved signal to noise statistics. In a cylindrical chamber with wall cathode 22, central rod anode 20 and insulating - e.g.Bn-ends 16, 18, Fe containing Fe 55  is co-deposited with 20-30% Ni on the inner wall to an activity of 1-15mCi, the alloy tolerating up to 300C in use. Up to 150V may be applied between the electrodes in an electron capture detector or 300V in a crosssection detector, either continuously or pulsed, e.g. 8Ás in every 80Ás, or pulse frequency modulated to maintain constant current, drawing ion current of the order of 1nA. Electron absorption by fluorinated or chlorinated hydrocarbon in 10<SP>-10</SP> concentration in air causes a detectable current fall of a few pA, with signal/noise e.g. 64 and 17 respectively.

Abstract: 1528081 Extruding variegated soap PROCTER & GAMBLE CO 30 Jan 1976 [31 Jan 1975] 03757/76 Heading C5D [Also in Division B5] A soap bar comprising a variegation of at least two colours, is stamped from a piece of variegated column 33 of the soap extruded from a plodder 3, the variegation being effected by delivering soap of each colour from separate plodders 1, 2 to a vacuum inlet 21 of the plodder 3, as noodles 8 and 12, which are cut at the outlets of the plodders 1, 2, the noodles blending together in the inlet and comprising pieces of 1/8 inch or less maximum transverse dimension from one of the plodders, and pieces of at least twice as great a transverse dimension from the other plodder. The difference between the sizes of the noodles, enhances association of the smaller noodles with the larger in the inlet 21. The stamping may produce a variegation of an orientation which is curved and/or diagonally of the bar. Preferably the base colour, e.g. white comprises the smaller noodles, present in a weight amount of 3 to 5 times the weight of the larger noodles, e.g. of blue colour. The larger noodles are preferably not greater than 16 times, and preferably are 8 to 12 times the transverse dimension of the smaller noodles, which may be <SP>1</SP>/ 32  inch or less, but is preferably not below <SP>1</SP>/ 16  inch. The noodles 8 and 12 may be of a section which is circular, rectangular, oblong, or star shaped, and each of the noodles 8, and 12, are preferably of the same length, and the smaller and larger noodles may all be of the same length, with the smaller noodles being of a length of  to 5 inches. The soaps preferably each comprise weight ratios of tallow to coconut soap of 95:5 to 5:95, and preferably 40% to 90% tallow and/or 10 to 60% coconut soap. The blending of the noodles in the vacuum inlet 21 may be effected by positioning of the plodders 1, 2 but is preferably effected by shoots 16, 18 adjustably mounted at hinges 15, 17 which direct each stream of the noodles 8, 12 to a confluence, from which they are directed to the upstream end of the inlet 21, by a shoot 20 also adjustably mounted at a hinge 19. The noodles preferably form a layer in the base of the inlet to avoid "starve feeding", the layer being of a depth which is even, or is greater at its upstream end, and feeding to the screw 25 of plodder 3 may be enhanced by a portion of the screw core tapering in the downstream direction in the region of the inlet, e.g. at 10 to 30 degrees effected by fixing sheet metal around the worm shaft 28. Each soap is fed to the plodders 1, 3 and may comprise waste soap, plodded and mixed with colour and additives in a stated processing sequence, Fig. 2 (not shown). The variegation is enhanced by cooling of the plodders, 1, 2, 3, and maintaining the moisture content differential of the soaps within 3% by weight.
