Abstract: 421,201. Discharge apparatus. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., Marconi House, Strand, London.- (Assignees of Essig, S. F. ; 334, Milne Street, Philadelphia, U.S.A.) July 31, 1933, No. 21524. Convention date, July 30, 1932. [Class 39 (i)] An electrode structure supported in the container of an electrical apparatus, for example, a photo-electric mosaic screen in a cathode-ray tube for television transmission, is oxidized uniformly and to a desired degree by producing a high-frequency field exteriorly and independently of the container and varying the intensity of the field with respect to different parts of the structure. The field may be produced by an electrode 30 on an insulating handle 32 and connected to a source 38 of high-frequency, high-voltage oscillations. The container 10 enclosing the mosaic screen 14 of silver globules on a mica sheet 16 is supported on an insulating block 20 and is evacuated and filled with oxygen at 1500 microns, the electrodes of the gun 12 being isolated. The field ionizes the oxygen and the electrode 30 is moved about until even oxidation of the screen produces an even colour change thereon. The oxygen is finally evacuated and the screen is photo-sensitized with caesium.

Title: Process for the manufacture of anti-rachitically highly active irradiated products of ergosterol
IPC: H01K3/02
Filed: 1932-08-03
Abstract: In the process described in the parent Specification wherein maleic or citraconic anhydride is used to remove inactive material from irradiated ergosterol, the initial irradiation is effected with unfiltered light from a magnesium spark.  The ergosterol is irradiated in benzene solution with exclusion of oxygen, unaltered ergosterol is separated in a known manner, and the remaining benzene solution is left to stand for six days with the addition of a slight excess of citraconic anhydride such as 1\ba1/2\be molecules of anhydride to 1 molecule of the irradiated product; at the end of this time 30 per cent of the material has combined with the anhydride. The benzene is distilled off with exclusion of oxygen, the residue is dissolved in alcoholic potash, and the solution diluted with water and shaken repeatedly with petroleum ether.  The extracts are dried and evaporated and the residue is dissolved in acetone and left to stand at 5 DEG  C. to crystallize; the crystallization may be assisted by cooling to -20 DEG  C.  The crystals are washed with cooled methyl alcohol and may be recrystallized from acetone or alcohol.  From the first mother liquor more crystals may be obtained by prolonged standing at a low temperature, if desired after repeated treatment with citraconic anhydride and further treatment as described above. Instead of removing unchanged ergosterol before the treatment with anhydride, the ergosterol can also be separated from the crystalline product in a known manner.

Title: Improvements in or relating to the treatment of wool and wool goods to reduce their tendency to felt or shrink
Inventor: SLASKI KAZIMIERZ ANTONI
Filed: 1955-08-02
Abstract: Wool or wool goods are treated with a dispersion of a plasticized or unplasticized synthetic resin which contains a cationic dispersing agent and has a pH less than 7, and are then treated with a solution of a halogenating agent at a pH of less than 7.  The synthetic resin may be polymethyl methacrylate, polybutyl methacrylate, polyvinyl chloride, polyvinyl acetate, polyvinylidene chloride, copolymers of vinyl chloride and vinyl acetate or urea-formaldehyde or melamine-formaldehyde. Plasticizers specified include dibutyl phthalate, dioctyl phthalate, dioctyl adipate, dioctyl sebacate and dihexyl sebacate, selected according to the resin used.  The dispersing agent may be cetyl pyridinium bromide, cetyl trimethyl ammonium bromide, tetradecyl pyridinium bromide or dimethyl-phenyl benzyl ammonium chloride.  The halogenating agent may be sodium or calcium hypochlorite, chlorine or bromine, Prior to the resin treatment, the goods may be treated with sodium sulphite.  The resin solution may be at 70 DEG  to 75 DEG  C.  The pH of either resin or halogenating solution may be adjusted with formic acid.  The goods may be after-treated with sodium sulphite or sodium bisulphite and may be rinsed.  Examples relate to the treatment of wool half-hose, yarn, knitting wool, fully-fashioned garments and fabric.  In Example 13, wool half-hose is scoured with an alkylphenol - ethylene oxide condensate solution which also contains sodium sesquicarbonate and sodium sulphite at a pH of 9-10.  After rinsing, the wool is brought to a pH of 5 with formic acid and is then treated with an aqueous dispersion at a pH of 5.0 and temperature of 70 DEG  to 75 DEG  C., of polymethyl methacrylate plasticized with dibutyl phthalate containing cetyl pyridinium bromide and formic acid, followed by treatment with a solution at a pH of 5.0 of sodium hypochlorite containing formic acid and afterwards with sodium sulphite and rinsing.  In a similar process in Example 22, wool garments are scoured, prior to the resin treatment, with a solution containing soap and the sodium salts of a mixture of sulphated higher secondary alcohols to which is added sodium sulphite.

Title: Magnetic memory system
IPC: G11C17/02
Filed: 1962-06-08
Abstract: 995,153. Magnetic date storage apparatus. AMPEX CORPORATION. June 8, 1962 [June 12, 1961], No. 22234/62. Heading H3B. A non-destructive memory matrix is formed by superimposing on the matrix of Fig. 2 part of the matrix of Fig. 1. The store of Fig. 1 is formed by placing drive conductors 12, 14 and 16 in one set of grooves in a magnetic plate and by placing sense windings 18 and 20 in an orthogonal set of grooves. To store information the junction of two wires is bridged by ferrite blocks 32, 34 and 36 the direction of which determines the polarity of an output pulse if a drive conductor is pulsed. The matrix elements may be considered to have three stable states as no pulse is produced if the corresponding bridge member is removed. The storage elements of the matrix of Fig. 2 are formed by the space between four apertures in a plate of magnetic material 40 to which drive conductors are coupled by threading through opposite corners of the elements. Information is stored by the direction of the flux as shown in Fig. 5, winding 60 being used to set " zero " and windings 70 and 82 being used to set " one." When the two matrices are superposed the storage elements of the Fig. 2 matrix acts as the bridge member of the Fig. 1 matrix and the remanent flux distorts the flux sufficiently to allow the reading system of the first matrix to be used to read nondestructively the information of the second. Specifications 937,267 and 995,154 are referred to.

Title: An improved arrangement for eliminating atmospheric and other interferences in radio-telegraphy and radio-telephony
IPC: H04B14/00
Filed: 1927-08-26
Abstract: 283,190. Plebanski, J. Jan. 7, 1927, [Convention date]. Atmospherics, eliminating; selective signalling; modulating systems.-Two modulated side bands of a single carrier-wave are phase-shifted at the transmitting end and are separately detected and differentially combined in the receiver; or several carrier-waves are simultaneously modulated by out-of-phase signalling currents, which are separately detected at the receiving end and combined together so as to form a rotary field, from which the desired signal is fed by means of a gomometer pick-up coil to the input of the receiving set. This eliminates atmospherics and similar disturbances. As shown in Fig. 3, three transmitting aerials V1, V2, V3 radiate carrier-waves which produce in the circuits of the receiving valves a rotary field. The coil a is then adjusted to a position in which the currents due to atmospherics are balanced out. Instead of using separate aerials, both carrier-waves may be radiated and received on a single aerial of the type . described in Specifications 211,151 or 271,414. The signal components may be split into several phases transmitted on one or several aerials, and similarly recombined in reception so as to produce a. rotary field from which, by suitable adjustment, atmospheric disturbances are eliminated. When only one carrier-wave is used, one side band is inverted or given a phase-displacement of 180. This may be done by first eliminating the carrier, and then adding a similar wave displaced in phase by 90. By using filters of the type described in Specification 211,151, the two side bands are separated and the signal components added cumulatively after detection. Or a frequency of 1,000 cycles can be used to modulate a frequency of 10,000 cycles and the resulting wave imposed upon a frequency of 100,000 with phase displacement and then applied with or without inversion of the side band, to a carrierwave of one million cycles, the audible component being separated out in stages at the receiving end.
