Title: Improvements in or relating to printing machines
IPC: G06K15/04
Filed: 1944-12-22
Abstract: 584,242. Typewriters &c. BRITISH TABULATING MACHINE CO., Ltd. Dec. 22, 1944, No. 25821. Convention date, Dec. 23, 1943. [Class 100 (iv)] [Also in Group XIX] A record card controlled printing machine with type carriers mounted for reciprocation, is characterised by each type carrier having two groups of type elements, one normally above and the other normally below a printing line, two actuators, one for elevating and the other for lowering the type carrier, an interposer normally connecting the type carrier to one of the actuators, means controlled by record cards for shifting the interposer to uncouple the type carrier from one actuator and couple it to the other, and means for moving the actuators concurrently, whereby the type carrier will be moved in accordance with the actuator to which it is coupled. Record cards, punched in accordance with the numerical code shown in Fig. 4, are sensed by a series of brushes 14, Fig. 3, under the control of a distributor 19 with an anti-clockwise rotating brush 20. As the brush 20 reaches the KH segment, perforations in this position on the card cause the energisation of corresponding electromagnets 22. Subsequently, magnets 21 are energized at times in accordance with the positions of the other perforations in the card. The type carriers 25, Fig. 1, are each moved by a member 46 connected by a link 44. An interposer 46 is hooked at 48 to normally engage a lever 50 attached by a spring 52 to an arm 32 which is rocked by cams 29 on the main shaft 28 through a link 31. In this way the interposer 46 is normally raised and so raises the type carrier 25 until the latter is arrested by a pawl 61 rocked into engagement with one of the teeth 60 on the carrier when the electromagnet 21 is energized and rocks a latch 65 clear of the spring- urged pawl. The presence of a KH hole, however, causes energization of the magnet 22 and this rocks a latch 57 allowing a spring-urged bell-crank 47, to which the interposer is pivoted, to rock anticlockwise and so disengage the hook portion 48 from the lever 50 and engage a hook portion 49 with a lower lever 51. The lever 51 is arranged to move in the opposite direction from the lever 50, being attached by a spring 54 to an arm 38 which is rocked by the arm 32 through a link 35 (shown dotted). Thus, after energization of the magnet 22, the interposer 36 moves the type carrier downwards until it is arrested by engagement of a pawl 63 with teeth 62. During the movement of the type carrier the arm 38 rocks an arm 74 into engagement with the bell-crank 47 to keep it in its set position. Bail arms restore the magnet latches &c. in the usual manner.

Abstract: 977,901. Air cushion vehicles. HOVERCRAFT DEVELOPMENT Ltd. July 13, 1961 [July 26, 1960], No. 26017/60. Heading B7K. A vehicle is supported by a gaseous cushion formed and contained by a gaseous curtain, at least part of which is recovered by recovery port or ports having means controlling the flow of gas to these ports. A vane 9, Fig. 1, in supply port 1 detects change in the efflux angle of flow from port 1 to operate a valve 12 controlling actuators 8 which are normally biased to move flaps 6 to close recovery port 4. Should an edge of the vehicle approach the ground, a greater part of the curtain flows outwardly to atmosphere and closure of flaps 6 prevents flow of air from the cushion into ports 4. Auxiliary air intakes supply the fans on closure of flaps 6. The flaps may be replaced by an inflatable member or a sliding flap and a pressure-sensing head between ports 1 and 4 may be used instead of vanes 9, Figs. 3, 4 (not shown). In Fig. 5 (not shown), the flaps are in the recovery duct close to the fan intake and an auxiliary intake duct also has controlling flaps. In Fig. 6 the intake to pump 30 positioned at the vehicle periphery, is controlled by a flap 37 which opens auxiliary supply duct 35 as it closes the recovery port 34. In the vehicle in Fig. 7, the recovered air is not re-energized and forms a further curtain issuing from port 49. Air is supplied from propeller 41 to supply duct 45 and to ports 52 which divide the cushion into sections. Specifications 935,823, 935,824, 935,826, 944,502, 944,503 and 944,504 are referred to.

Abstract: 246,592. Robinson, J., and Walker, N. Cox-. Nov. 1, 1924. Thermionic amplifiers and defectors.-Relates to thermionic amplifiers utilizing the autoquenching or squegger effect, and tuned to oscillate at the same frequency, or at some harmonic of the frequency of the received waves, and consists in employing, in place of the usual non- inductive grid leak, an iron-cored or air-cored inductance, or a low-resistance conductor. As shown in Fig. 1, the grid condenser 3 is bridged by an iron-cored inductance 9, the value of which may be varied by means of a movable core or bv a short-circuited auxiliary winding. The receiving telephones 7 may take the place of the inductance 9, as shown in Fig. 3. In Fig. 5, the shunting inductance is replaced by one winding 16 of an iron-cored transformer, the other winding of which is connected in the plate circuit, so that an additional reflex action is obtained. The telephones may be in series or parallel with the winding 17, and a separate plate battery may be dispensed with. Fig. 8 shows a modified arrangement in which an air-cored inductance 21 forms the grid leak, the effect of the usual grid condenser being obtained from the self capacity of the windings and the batteries. A tuned lowfrequency circuit, such as a transformer 22, 23 and a shunting condenser 24, or a shunted chokecoil, may be inserted in the plate circuit to increase the desired effect.

Title: Process for the desalination of sugar solutions by electrodialysis
IPC: C13B20/18
Filed: 1972-06-07
Abstract: 1351910 Purifying sugar solutions; electrodialysis TAITO K K and ASAHI KASEI KOGYO K K 7 June 1972 [7 June 1971] 26624/72 Headings C6B and C7B A sugar solution is desalinated by electrodialysis between cation exchange membranes K and non-selective ion-permeable membranes P made of a polymer having a vinyl alcohol structure in which the mole fraction of vinyl alcohol groups is from 10 to 100%. The apparatus shown has concentration and dilution compartments C, D, respectively, and electrodes E. The electrodialysis may be used in addition to a conventional sugar refining process, e.g. carbonation. Production of the material for the P membranes is by a copolymerization process, e.g. an emulsion or suspension polymerization carried out in a closed vessel at a temperature of from 0 to 120 C, using at least one vinyl ester, at least one monomeric compound copolymerizable therewith, an initiator, and a solvent. Suitable vinyl esters include vinyl formate, vinyl diethyl acetate, vinyl t-butyl acetate, vinyl benzoate, vinyl 2, 4-dimethyl pentanoate, vinyl laurate, vinyl isocaproate, vinyl salicylate, vinyl palmitate and vinyl sulphonate, and suitable compounds that are copolymerizable therewith include vinyl halides, unsaturated mono- and di-basic acids and their esters, and unsaturated aliphatic and vinyl-substituted aliphatic and aromatic hydrocarbons. Suitable initiators are those employed for free radical copolymerizations, e.g. organic and inorganic peroxides, and azobisnitriles. After the membrane has been formed, e. g. by casting, and some or all of the ester groups have been hydroxylated or saponified to hydroxyl groups, it may be heated and partially esterified to provide it with dimensional stability in aqueous solutions. In one example the P membrane is reinforced by a woven fabric of polypropylene fibres.

Abstract: 980,413. Forced flow steam boilers. HEAD WRIGHTSON & CO. Ltd. Oct. 23, 1962 [July 24, 1961], No. 26804/61. Heading F4A. A forced flow, once through boiler heated by the CO 2  coolant of a nuclear reactor and generating steam at high and low pressures, comprises a plurality of tubes arranged vertically within a casing and carrying the working fluid in one direction whilst the heating fluid flows through the casing in the other direction, the overall heat transfer coefficient required in each section of the boiler being achieved by providing the tubes in the region of that section with appropriate internal and external heat transfer promoting means. Figs. 1a and 1b show the boiler heat exchanger which is disposed within a casing (not shown) through which the heating gas flows downwardly. It consists of a bank of vertical tubes 1 including H.P. and L.P. economizer, evaporator and superheater sections and a reheater section. The H.P. and L.P. tubes, H, L respectively extend between inlet headers 2 and outlet headers 3 whilst the reheater tubes R extend between inlet and outlet headers 4, 5, space for the reheater tubes being provided by bifurcating the L.P. tubes L at 6 whilst dummy tubes 7 are inserted below the lower bifurcations to balance the arrangement. The various sections of the H.P. and L.P. circuits are shown on the drawing. Where the tubes pass through these sections they are provided internally and externally with fins &c., arranged to provide the required heat transfer coefficient for the particular section. For example, as shown in Fig. 3, the tube has a series of multi-start helical fins 8 on its outer surface and splitter plates 9 which assist the fins in effecting turbulent gas movement between the tubes whilst the inside of the tube has spaced splines 15 formed thereon. Alternatively, Fig. 4, the tube contains a core 12 on which is mounted a helical guide plate 10 which engages with circumferentially spaced splines 14 which increase the turbulence of the working medium flow.
