Title: Foldable telephone set
IPC: H04M1/03
Filed: 1967-03-22
Abstract: In a telephone handset (Fig. 2) comprising a mouthpiece 22 and a receiver 20 hinged together, the mouthpiece 22 includes a microphone, and a dial 38 is recessed in a cavity in the receiver 20. The handset may be closed, the mouthpiece 22 fitting into the dial cavity (Fig. 1, not shown). On opening the handset, two sets of switch contacts 46, 48 (Fig. 3a) are operated by a lever 50, 52, respectively, and a concave wedge 56 on each outer spring contact ensures that interruption of contact does not occur by minor relative oscillation of the two parts 20, 22. A helical spring 60 aids maintenance of the handset in the open position. Cable 76 between the two parts 20 and 22 runs from one side of part 20 to the other side of part 22 through an insulating tube 78 parallel to the axis of rotation 64. The receiver 20 comprises a base-plate 26 and a cover-plate 30. The mouthpiece 22 comprises a base-plate 28 and a cover-plate 32. The underside of the mouthpiece 22 has a U-shaped rubber pad (150), Fig. 13 (not shown), for ensuring sufficient grip of the base when placed on a horizontal surface and for absorbing shock when putting down the apparatus. A latch (156), Fig. 14 (not shown), provides stable closure and may be opened against spring action by pressing a bolt (160). A printed circuit board (88), Fig. 4 (not shown), has at opposite ends a choke (96) and a transformer (94) between which is fitted a circuit sub-assembly (86). The sub-assembly is fixed to the rear of the receiver 20 by two U-shaped brackets (100) one of which accepts the transformer (94) while the other accepts the choke (96). The receiver transducer and microphone are held by metal straps also described in Specification 1,151,785.

Title: Process for producing shrink-resistant wool by treatment with hypochlorous acid and cationic hydrophilic resinous condensation product
IPC: D06L4/24
Filed: 1967-07-29
Abstract: Wool, e.g. in the form of top, wool serge or knitwear, is shrink-proofed and rendered antistatic by substantially uniformly treating it with an aqueous solution of hypochlorous acid at an acid pH to modify it to such an extent that there is a reduction in shrinkage, when compared with art untreated control which is subjected to the same washing test, of at least 15%, then substantially uniformly impregnating it with a water-soluble cationic hydrophilic resinous condensation product which is obtainable by (a) reacting a mono-and/or polyfunctional derivative of a polyalkylene oxide with a polyamine in such proportions that the resulting polyamine contains a plurality of reactive hydrogen atoms each of which is attached 'to a nitrogen atom and (b) then reacting the product with at least one bifunctional compound containing at least one epoxide or alpha-halo-betahydroxyalkyl group, at least the latter part of the treatment with the cationic hydrophilic resinous condensation product being carried out under alkaline conditions, and then heating it e.g. at 70 -120 C. The aqueous solution of hypochlorous acid may be obtained from an aqueous solution of an alkali metal dichloroisocyanurate to which an acid has been added, a solution of dichloroisocyanuric acid in aqueous tetrasodium pyrophosphate which has been acidified or an acidified solution of a hypochlorite, and the treatment with hypochlorous acid is preferably applied from a short liquor bath having a pH of 3-6 to which permonosulphuric acid or an alkali metal salt thereof and a wetting agent, e.g. a condensation product of trimethyl nonylphenol with 6 moles of ethylene oxide, may be added. After treatment with the hypochlorous acid the wool may be treated with an aqueous bath containing sodium sulphite. The cationic hydrophilic resinous condensation product may be prepared by the reaction of ethylene diamine, diethylene triamine, triethylene tetramine, dipropylene triamine, paraphenylene diamine or 1,4- diaminio-cyclohexane with a polyethylene oxide or polypropylene oxide having 3-70 ethereal oxygen atoms and a molecular weight of 400- 2,000 the terminal hydroxyl groups of which have been reacted with phosgene, chlorosulphonic acid, epichlorohydrin or a compound forming a sulphuric ester grouping, in the presence of boron trifluoride or stannic chloride, the resulting product then being reacted with epichlorohydrin, dichlorohydrin or polyalkylene glycol bis-chlorohydrin ether. The cationic hydrophilic resinous condensation product may be applied to the wool from a bath having a pH of 7-10 which may contain an anionic wetting agent, e.g. the sodium salt of a sulphated fatty alcohol.

Title: Start-up system for combined circulation steam generator
IPC: F22B29/12
Filed: 1967-12-02
Abstract: During start-up of a forced through-flow boiler with partial recirculation, throttle valves BT, BE are closed and the increase in volume of the heated working fluid is relieved through a by-pass 44 leading from a point between the feedwater heater 28 and economizer 30 to a point, such as the deaerator 26, in the low pressure part of the feed circuit. Throttle valves 46 and throttling orifices or capillary devices 48 are arranged so that the pressure drop thereacross does not produce flashing until the fluid reaches the deaerator 26. One valve 46 may be controlled by the passage at the inlet to economizer 30. At a later stage of start-up, the valve BE is opened to allow the fluid from the evaporator 32 to flow to a separator 36, the water from which is returned to condenser 20 whilst the steam flows through pipe 37 to the superheater 34. In Fig. 2 the high pressure feed pump 18 is provided with a return by-pass 54 leading back to deaerator 26 and the pipe 58 relieving the excess fluid during start-up is connected to the by-pass 54.

Title: Converter for coded electrical signals
IPC: H03M1/66
Filed: 1968-02-10
Abstract: A non-linear digital-to-analogue converter comprises input terminals 1, 2 for the least significant digits and a linear decoder A for producing a proportional voltage V A , input terminals 3, 4, 5 for the most significant digits, a pedestal voltage generator B providing a fourunit pedestal voltage V B when any of the input digits at 3, 4, 5 are " 1 ", a decoding matrix E controlling a multiplier D in accordance with the numerical value of the digits at 3, 4, 5 and a summer C adding the outputs V B and V A and applying the sum to the multiplier. The conversion characteristic comprises seven straight line segments giving an approximation to an exponential curve. The multiplier comprises a series of resistors any one of which may be connected by a switching signal on a corresponding output from the matrix E. The first two resistors are equal so that the first two segments of the characteristic curve have the same slope. Successive segments after the second each have twice the slope of the one before. Instead of using a separate switch and resistor for each digit value, a combinational arrangement may be used. The digits on terminals 3, 4, 5 control the pedestal generator B through OR gate G. An offset signal equal to half a step may be added to output by being applied at a third input to the summer. The code is symmetrical for positive and negative values, the polarity of the signal being indicated by a further digit.

Title: Foundry moulding composition
IPC: C04B28/26
Filed: 1969-07-24
Abstract: Foundry moulds are produced by adding to particulate materials coated with an alkali metal silicate from 10 to 100%, preferably 40-60%, by weight, based on the weight of the alkali metal silicate of a hardening agent selected from sodium formate or an hydroxide of an element of Group II of the Periodic Table or any combination thereof before or during the shaping operation, and hardening the finished article in the absence of added carbon dioxide.
