IPC: C25B1/26
Filed: 1971-07-07
Abstract: 1346656 Recovering chlorine and hydrogen electrolytically BADISCHE ANILIN - & SODA - FABRIK A G 7 July 1971 [8 July 1970] 31858/71 Heading C7B In a method of recovering chlorine and hydrogen from aqueous hydrochloric acid in a diaphragm cell, the acid has a concentration of 18-28 wt per cent and during its passage through the cell the acid is consumed by not more than 2 wt per cent. The near temperature is 75-90C and the current density 2000-5000 A/m<SP>2</SP>. A high rate of flow of acid through the cell lowers the bubble overpotential.

Abstract: 1466751 Cooling glass forming moulds EMHART (UK) Ltd 8 July 1975 [22 July 1974] 32311/74 Heading C1M [Also in Division F4] The forming mould in a glass forming system is cooled by cooling means comprising a chamber through which a cooling fluid flows and a fluidized bed, between the chamber and the mould. In Fig. 1 the blow mould 1 is surrounded by a cavity 8, supplied with a bed of particles 11  (e.g. of iron or brass shot, graded sand or glass ballotini) which may be fluidized by gas (e.g. air) from pipe 12 and diffuser 13, and a cooling chamber 5 supplied with coolant (e.g. water or possibly other liquid or gas) through pipes 6 and 7. When cooling is required the solenoid valve 16 allows gas to enter tube 12 under the control of electronic timing unit 17 or in response to signals from temperature sensors in the mould block 2. The cooling rate may be increased by cooling pipes in the fluidized bed or fins on the mould block or decreased for selected parts of the mould by the introduction of shielding plates to the mould block surface. Reference is made to the use of the invention in glass bottle moulds in an I.S. machine.

Title: Improvements in thermionic valve amplifiers

Filed: 1946-10-31
Abstract: 628,601. Valve amplifying circuits. YARBOROUGH, E. H. COOKE-. Oct. 31, 1946, No. 32365. [Class 40 (vi)] A thermionic valve amplifier for obtaining an output voltage across a load in the anode circuit which is in phase with the input voltage comprises a valve having two control grids biassed at or near earth potential; the cathode circuit contains a resistance having a value which is large compared with the reciprocal of the control grid mutual conductance, and is connected to a negative supply terminal, and the input is applied to that control grid which is nearer the cathode. In the Figure the input is applied between terminals 5, 6 and the output taken from terminal 4, terminal 9 is connected to a negative potential and terminal 8 to a positive potential with respect to earth. As the input voltage increases the cathode potential follows and the potential of the suppressor grid 3 is thus reduced with respect to cathode, there is thus a reduction of current flow to the anode and its potential rises. Additional negative feedback may be obtained by coupling the anode to suppressor grid.

Abstract: 1470492 S-substituted sulphonylethyl cellulose RIEDEL-DE HAEN AG 5 Aug 1975 [5 Aug 1974] 32728/75 Heading C3A Ion-exchange materials have groups of the formula bound to a cellulosic matrix. R is a residue containing the ion-exchange group or groups. The ion exchange groups are preferably found in a residue of a known metal-ion complexing agent such as 8-hydroxyquinoline, salicylic acid, 4,5-dihydroxyphenol-1,3-disulphonic acid, alizarin S, morin or chromotropic acid. The group may also be in an aromatic amine residue. These functional-group-containing residues may be directly linked to the -SO 2 - group (i.e. they may be R) or there may be a linkage between them and the -SO 2 - group. In this case R is preferably in which R<SP>1</SP> represents the functional residue. Two methods of preparation of these materials are disclosed. In the first a compound of formula R-SO 2 -CH=CH 2 , or a compound yielding such a compound under the reaction conditions, is reacted with the cellulosic compound. This is exemplified by the reaction of cross-linked, amorphous cellulose with under alkaline conditions. Sodium sulphate splits off, leaving the vinyl sulphonyl compound to react with the cellulose. Example 1 illustrates the linkage of salicyclic acid to cellulose by this process. The second method, a p-aminophenyl derivative p-H 2 NC 6 H 4 -SO 2 CH 2 CH 2 OSO 3 Na is reacted with cellulose as above then diazotized and coupled to the residue containing the functional groups. Example 2 describes the attachment of 8-hydroxyquinoline in this fashion. The preferred cellulosic materials are microcrystalline and amorphous cellulose, preferably cross-linked with formaldehyde.

The fibrous sheets may be of paper, cardboard, cellulose pulp, fabric or asbestos and the synthetic resin may be a phenol-, cresol- or urea-formaldehyde resin. The synthetic resin used for filling the cavities may contain a filler, e.g. paper, asbestos, textile or wood fibres, silica or mica. The structure may comprise an imperforate sheet 7, Fig. 3, between perforated sheets 9, 10 with outer imperforate sheets 6, 8. The perforations in sheets 9, 10 may be staggered in relation to one another. The cavities formed by the perforations may be of different axial section. The product may be used in making an electrical heating unit (Figs. 9, 10) in which the resistance wire 64 is wound in a flat helix on strip 63 formed from sheets of fibrous material impregnated with synthetic resin similar, but perforated, sheets 65, 66 are arranged on opposite sides of the strip 63 and together with further superposed sheets 69, 70 enclose terminal bars 67, 68.
