Filed: 1972-11-13
Abstract: 1416875 Sorting sticks MARTIN ROBERTSON & BAIN Ltd 13 Nov 1972 52234/72 Heading B2H [Also in Division B8] Sticks e.g. asparagus shoots, celery, rhubarb, broccoli, carrots and fish, are classified according to their orientation and length by an apparatus comprising conveyor belts 29b, 52 and 95 and rollers 40b and 97. When an asparagus shoot A is launched tip first by the roller 40b and conveyor belt 29b and it is of sufficient length, the tip of the shoot is inserted into the gap between the discharge belt 95 and the roller 97 and the shoot is carried away by the belt 95. When a shoot A is launched butt first it droops in the manner shown in broken lines in Fig. 20 because of the more limber character of the tip portion of the shoot and falls onto a conveyor belt 52. If a shoot is too short to bridge the gap between the conveyor belts 29b and 95, it falls through the gap onto the conveyor belt 52.

Title: Process for the catalytic hydrogenation of block copolymers
Inventor: QUAM MYRON G
IPC: C08F8/04
Filed: 1964-12-24
Abstract: Block copolymers of conjugated dienes and vinyl substituted aromatic hydrocarbons are hydrogenated by contacting a solution of the polymer in an inert solvent with hydrogen in the presence of a catalyst comprising the reaction product of a compound of nickel, manganese, molybdenum or tungsten with an aluminium-containing reducing agent, e.g. an organoaluminium compound, aluminium hydride, lithium aluminium hydride and aluminium powder.  The catalysts may be used either in the form of a slurry or on a support, e.g. kieselguhr.  The resulting solutions of hydrogenated polymer may be used in the productions of films and fibres, or they may be converted into latices by the addition of water and the removal of emulsifier. Alternatively, the hydrogenated polymer may be recovered from the solution and used in the production of mouldings and adhesive.  The examples describe the hydrogenation of polystyrene - polyisoprene-polystyrene block copolymers using, as catalysts, cobalt acetate and octoate and nickel acetate and acetylacetonate reduced by aluminium triethyl.

Abstract: 1,086,440. Selective printing. SIEMENS A.G. Dec. 10, 1965 [Dec. 11, 1964], No. 52533/65. Heading B6F. Teleprinters having a movable type print or character selector quadrant carrier 1 movable along the printing line on a guide rail 2 which is displaceable vertically with the quadrant carrier are provided with a type fount or case shift mechanism for shifting of the carrier vertically into one of three type founts or case positions. Case shift is effected by an electromagnet 9 mounted on a guide rail 3 for concomitant movement with the quadrant carrier 1 and provided with an armature plunger 8 which operates a bell-crank lever 7 fulcrumed on a shaft 5a of one of the rollers 5 forming the carriage 4 for the electromagnet 9 and articulated to a coupling lever 10 which in turn is articulated to a locking selector quadrant 11 to displace the latter angularly which effects vertical displacement of the selector quadrant carrier 1 and its rail through one of the three type fount or ease shifts. Accurate adjustment is maintained by a second lever 13 which forms a parallel linkage with the lever 10. In another embodiment the coupling lever is articulated directly to the armature plunger of the electromagnet 18, Fig. 3 (not shown), and the lever 13 is articulated to the electromagnet core. In a further embodiment the lever 23, Fig. 4 (not shown), is provided with a guide slot 23a and its end terminates in an adjusting cam 23b to serve as a guiding system for the case shift mechanism.

Title: Voltage stabilizers
IPC: H02M5/27
Filed: 1975-12-05
Abstract: 1510644 Automatic voltage control ROBAND ELECTRONICS Ltd 5 Dec 1975 [5 Dec 1974] 52719/74 Heading G3R [Also in Division H3] A voltage stabilizing circuit includes A.C. input and output terminals between which there is connected a compensating arrangement which introduces an alternating voltage component dependent on the difference between the circuit output voltage and a reference voltage. The arrangement includes a solid state switching circuit, operating at a high frequency compared with the supply, which connects voltages of opposite polarity with a variable duty cycle. As shown in Fig. 2, a compensating circuit 10 is connected between terminals X, Y in one supply lead between input terminals L, N and a load R. A transformer 30 measures the load voltage and supplies a rectified signal to a junction point 35 for comparison with an output from a reference source 36. If only RMS or mean voltage stabilization is required, the reference may be a D.C. voltage, but if waveform stabilization is required, the desired waveform must be produced by the source 36 which is phase-locked to the supply by a loop circuit 40, Fig. 5 (not shown), including NAND gate circuitry controlling a frequency determining FET (68). The output from junction 35 is passed through a feedback amplifier 41 to a comparator circuit 43 which also receives an input from a ramp generator circuit 44, Fig. 6 (not shown). The frequency of the ramp generator may be 200 kHz, and the output of the comparator 43 will be a series of width modulated pulses at this frequency. The pulses are passed through a NAND gate control circuit 45, Fig. 7 (not shown), producing signals for switching alternately transitions 16, 19 which connect transformer windings 11b, 11c respectively to the supply terminal X. The duty cycle of the pulses determines the magnitude of the compensating voltage which aids or opposes the supply from source terminals L, N. A circuit (46) responds to excessive current in the compensating circuit to inhibit the production of switching signals by the control circuit 45, Fig. 7 (not shown). An overvoltage protection circuit (48), Fig. 8 (not shown), including a triac (235) fired by an inverse pair of Zener diodes (231, 232) may short the terminals, X, Y. A clamping circuit 47 limits the voltage appearing between terminal Y and the common lead 20 so as to protect the switching transistors 16, 19. The circuit 47 includes parallel branches each formed by a diode and opposed Zener diode.
