Filed: 1957-12-19
Abstract: 861,153. Measuring displacement electrically. T. I. (GROUP SERVICES) Ltd. Dec. 18, 1958 [Dec. 19, 1957], No. 39438/57. Class 40 (1). [Also in Group XXXV] Movement is measured by positioning a conducting screen A between conductors, one of which is fed with an A.C. signal so as to vary the signal induced in the other. As shown in Fig. 2, coils P1, P2 are fed from a common oscillator O and coils S1, S2 are connected in opposition so that their combined outputs are zero when the screen is symmetrically positioned as shown and increases as the screen moves away from the central position, the phase sense of the combined output being determined by the direction of movement. The combined output is fed to the grid of V1 (Fig. 3), where it is amplified and phase compared at the grids of V3, V4 with a reference signal from oscillator O which is phase split, amplified at V2 and fed to the suppressor grids of V3, V4. The difference outputs on V3, V4 are measured by valve volt meter V5 which comprises a centre zero meter M. A tapered portion may precede the screen proper to ensure the production of an error signal of correct sign before the screen reaches the region of the coils (Fig. 5, not shown). The device may be used in a load cell for weighing.

Abstract: 1,101,197. Control of D.C. motors. MEFINA S.A. 5 Sept., 1966 [17 Sept., 1965], No. 39561/66. Heading H2J. A series motor M is supplied from A.C. terminals a, b through thyristor T1 whose gating circuit comprises transistor T2 associated with capacitors Cl, C2. When terminal a is positive, the capacitor C2 is charged through the motor armature and a network comprising resistor R10 which is adjustable manually. The transistor T2 becomes conductive to fire the thyristor T1 when the voltage across the capacitor C2 exceeds a reference voltage developed across the capacitor C1 The capacitor C2 is then discharged through a circuit comprising resistor R9 across which a voltage is developed which represents the motor current, the residual voltage at the end of the discharge period being increased if the motor current rises in value. The duration of the subsequent charging period of the capacitor C2 is thus reduced to advance the firing of the thyristor whereby the motor voltage is increased when the motor is subjected to a greater load. When terminal b is positive, the capacitor Cl is charged through circuit elements R1, C2, R6, D2 and D3, and discharges through resistors R1, R2 when the voltage across terminals a, b changes polarity. The ignition of the thyristor T1 is thus advanced when the mains voltage drops to avoid unwanted variations in the motor torque.

Title: Improvements in or relating to methods of jointing electric cables insulated with thermoplastic material
IPC: H02G15/196
Filed: 1959-11-23
Abstract: 916,521. Insulating cable joints. PIRELLI S.p.A. Nov. 23, 1959 [Nov. 26, 1958], No. 39621/59. Class 38 (1). A method of jointing a cable insulated with thermoplastic material comprises winding around the junction of the conductors a non- adhesive tape 7 whose characteristics are similar to those of the thermoplastic insulation of the conductors. Further tape 8, which may be of partially conducting cloth or a partially conducting material whose characteristics remain unaltered at the melting temperature of the thermoplastic tape 7, is then wound on the tape 7. The jointing zone is next heated, e.g. in a paraffin wax bath or in an oven, at a temperature higher than the softening temperature of the tape 7, and the taping 8 acts as a substantially non-deformable mould for the material of the tape 7. Subsequently, and after slow cooling, the taping 8 is removed or left in position and, after securing a screen 9 to the existing screen 3, an outer sheath 12 is applied in a manner similar to that used for the insulation immediately surrounding the joined conductors. Finally, a second winding of inextensible tape is applied and the whole is heated at a temperature higher than the softening temperature of the material constituting the sheath 12. After slow cooling, the second winding of inextensible taping may be wholly removed or left in position. Examples are given of the jointing of cables having P.V.C. and polythene insulation.

Title: Hydrogenation of carbohydrates
Filed: 1959-11-24
Abstract: Monomeric polyhydric alcohols are obtained from a saccharidic composition containing both reducing sugars and polysaccharides hydrolyzable to reducing monosaccharides wherein the ratio of available to potential reducing groups is at least 2 to 3 by hydrogenating said composition in substantially neutral solution under hydrogen pressure, e.g. 1000 to 3000 p.p.s.i., at from 125 DEG C. to 160 DEG C., in the presence of a hydrogenation catalyst, e.g. nickel on diatomaceous earth, until the bulk of the reducing groups are hydrogenated, adding from 0.05% to 1% by weight based on the original saccharides, of a mineral acid having an ionization constant of at least 10-3, e.g. phosphoric acid, hydrochloric acid or sulphuric acid, and subjecting the acidified solution-catalyst mixture to hydrogen pressure at a higher temperature, e.g. 1000 to 3000 p.p.s.i. at from 200 DEG  to 220 DEG C., whereby hydrolysis of the said polysaccharide ensues and the p  resulting monosaccharide is hydrogenated substantially as rapidly as it is formed, continuing the concurrent hydrolysis and hydrogenation until the sum of available and potential reducing groups is less than 0.7%, and separating the catalyst from the resulting monomeric polyhydric alcohol solution. The process is applicable to reducing disaccharides such as maltose or lactose which contain one available and one potential reducing group per molecule.  Also suitable are acid hydrolyzed starch products with a dextrose equivalent of at least 40.  The process may be effected continuously using 3 vertical tubular reactors, a slurry of sugar solution and catalyst together with an excess of hydrogen under pressure being conducted in upward direction through each in series and phosphoric acid being injected into the bottom of the second reactor.

Title: Improved process and apparatus for the continuous production of building elements of glass
IPC: C03B13/08
Filed: 1961-11-07
Abstract: In the continuous production of structural building elements of glass, two or more glass ribbons in a plastic condition from one or more planes are continuously fed to an assembly station and joined together by a constant heat <PICT:0992233/C1/1> <PICT:0992233/C1/2> <PICT:0992233/C1/3> <PICT:0992233/C1/4> <PICT:0992233/C1/5> <PICT:0992233/C1/6> supply, the assembly and joining of the ribbons being effected over deflector and support means without further alteration in cross-section of the ribbons and with substantially only rolling friction.  Before being fed to the assembly station, one or more of the glass ribbons may be pre-shaped.  As shown in Fig. 1, molten glass is fed from a furnace 1 through nozzles 2 to tanks 4, the glass being metered by plungers 3 and fed where necessary through heated tubes 5.  Electrodes 6 maintain the glass molten and glass ribbons are drawn from the tanks 4 by pairs of rollers 7, reinforcing wire, if desired, being fed into the glass over rollers 8.  The ribbons then pass over conveyer rollers 9 and deflection rollers 10 with heating elements 11 arranged to maintain the glass plastic.  The lower ribbon shown passes through pre-shaping means 12 to 15 to form the ribbon to a channel shape and then over conveyer rollers 16 to join a top ribbon over roller 18 on to a mandrel 17 which supports the assembled ribbons while they are joined together by heat from burners 19, 20.  As shown, the two ribbons will be formed into a hollow box-girder.  As shown in Fig. 2, unshaped ribbons 22 fed by rollers 21 pass over deflector rollers 23 on to a mandrel 17 with counter rollers 24 to 28, the ribbons being joined to form a box-girder.  Similarly, I-beams and Z-beams can be formed and, as in Fig. 20, the parts of the beams are held in position by rollers such as 114 to 117 which are mounted to rotate at the same speed as the glass ribbon or beam.  The internal mandrel 17 is similarly formed with rollers on all sides and as in Fig. 4, the rollers 70 are mounted in graphite bearings 73 in a casing 72.  The pre-shaping means 12 to 15 shown in Fig. 1 includes a ramp 12 similar to that shown in Fig. 9, in which the glass ribbon has its edges turned progressively up by the angled edges of the ramp 76 to form a channel shape, the ramp 76 being mounted on supports 74, 75 and the angle and position of the ramp 76 adjusted by raising or lowering a roller 77. As shown in Fig. 12, the pre-shaping means may comprise pairs of rollers 81 to 83, one pair at each end of a roller 90 so that a ribbon formed by rollers 81 passes over rollers 82 to the rollers 90 and the edges are progressively raised by the pairs of rollers to form a channel shape. The pre-shaped ribbon is then fed by guide rollers 92 to 99 with lateral pulleys 106 which enclose the glass channel, to the assembly station, not shown in Fig. 12.
