Abstract: 1434135 Television MATSUSHITA ELECTRIC INDUSTRIAL CO Ltd 20 June 1973 [20 June 1972] 29343/73 Heading H4F [Also in Divisions G4-G6] Video playback apparatus includes rotary heads whose output is supplied via rotary transformers 24-29 and which are sequentially switched under control of vertical synchronizing signals in the reproduced signal and a signal representative of the angular position of the heads, to produce slow-motion reproduction of fields on the tape. The transformers have fixed cores 27-29 and rotating cores 24-26 connected to the heads. The head signals are amplified at 32-34, combined at 38 and demodulated at 40 before the vertical synchronized signals are separated at 42 and applied to the trigger inputs T of J-K flip-flops 45-47 forming a ring counter 44. A reset pulse is applied to their set inputs 5 once every head revolution from a transducer 50 responsive to a magnet 48 on a disc 49 rotating with the heads. The flip-flop outputs are applied to transistors 35-37 to switch the head circuits as required. The distance between heads on the tape is slightly greater than two field lengths. The arrangement is similar to that of Specification 1,376,707.

Title: Improvements in or relating to electric motor controllers

Filed: 1931-10-27
Abstract: 378,265. Master control of D.C. motors. IGRANIC ELECTRIC CO., Ltd., 147, Queen Victoria Street, London.- (Assignees of Kuhn, C. W.; c/o Cutler- Hammer, Inc., 12th Street, Milwaukee, Wisconsin, U.S.A.) Oct 27, 1931, No. 29763. Convention date, Oct. 27, 1930. [Class 38 (iii).] Armature control. -Closure of switch 3 causes switch 1 to close, its winding being supplied through impedance r in parallel with armature A and winding 2a. As the motor accelerates, the current in winding 2a decreases, reverses, and increases in the opposite direction to a value sufficient to close switch 2 and exclude starting resistance R. Opening of switch 3 causes opening of switch 1 and closing down of the motor with gradual decrease of current in winding 2a to zero. It can be arranged that if switch 3 is reclosed before the motor has slowed down sufficiently, the switch 1 is not reclosed as its winding can only receive current through the impedance r. When however the motor has slowed down sufficiently the current in winding 2a can reverse and augment that through the impedance r to effect reclosure of switch 1.

Varying gear ratio of driving-gear according to tension of hoisting rope. - In cranes, derricks, &c. variable speed gearing is placed between the prime mover and winding drum and the gear ratio is varied automatically by the hoisting cable according to the load. The hoisting cable 4, 5 passes over pulleys 2, 3 at the head of the jib and is attached to the winding drum 7 and to a pivoted lever 18. An eccentric or crank 11 on the shaft of the prime mover 9 imparts reciprocating movement to a slotted link 12 which is pivoted at 13 to a longitudinally movable rod 14. The lever 18 bears against a stop 20 on the rod 14 and moves the rod to the left against the resistance of the spring 17 when a load is suspended from the hook 6. The lever 18 is held in the position of equilibrium by a ratchet rack 26 which is brought into engagement by the action of the cable on a jockey pulley 27. Slide blocks 21, 24 working in the link 12 and guide 23, respectively, are connected bv a stud 24 carried at one end of a link 25. The other end of the link is connected by a one-way clutch to a shaft 10 which is geared to the drum 7. The angular movement imparted to the shaft 10 varies inversely as the distance through which the rod 14 is moved, i.e. as the load. In order that the movement of the shaft 10 may be almost continuous, the shaft 9 may actuate a series of links 12 by a series of eccentrics, &c. set at equal angles around the circle.

Title: Improvements in or relating to calcium carbonate
Inventor: JR SAMUEL FLEMING CRAWFORD
IPC: C01F11/18
Filed: 1961-08-21
Abstract: The aragonite crystal form of calcium carbonate is produced by adding a continuous stream of sodium carbonate solution to an aqueous, continually agitated slaked lime slurry, which may contain caustic soda, until a concentration of 120-250 g./l. of caustic soda is formed, the temperature of the mixture being maintained between 150 DEG  F. (66 DEG  C.) and its atmospheric boiling point.  The sodium carbonate may be added from a plurality of sources to ensure rapid mixing with the slaked lime, which is present preferably as a slight stoichiometric excess, i.e. up to 5%.  Example 3 refers to lime being slaked in an agitated baffled area of a tank to which recycled caustic soda is added.  The resulting slurry flows under the baffle to the main part of the tank and then through an overflow pipe to the agitated baffled area of a similar tank where sodium carbonate solution is continuously fed in.  The mixture flows as before into the main part of the tank where further sodium carbonate is added until a concentration of 160 g./l. caustic soda and 151 g./l. calcium carbonate is formed, the temperature being maintained at 200-210 DEG F. The mixture then passes to a third agitated tank whence it is continuously withdrawn via an underflow pipe to a thickener where the aragonite calcium carbonate is separated from the caustic soda solution a portion of which is recycled to the slaker.

Abstract: 1,270,307. Drying apparatus. E. N. MAY Jnr. 16 June, 1969 [17 June, 1968], No. 30437/69. Heading F4G. Apparatus for drying particulate material with a gas has a drying chamber 2 with material inlet 27 and outlet 28 and gas inlet and outlet, and means for causing the gas to flow through the material after being dried by a desiccant in a removable cartridge 20 in a housing 4. Particulate material continuously enters the drying chamber 2 through a door 27 and leaves through a gate valve 28. In the chamber 2 the material is dried by heated, dry air which enters the chamber from a duct 14. The air is distributed evenly through the material by "spreader cone 13" and directing members 19, and leaves the chamber via duct 11. The humid air then passes to a filter 8 which removes any material entrained therein. After the filter 8 (or it may be before) is a blower 3 which circulates the air to the housing 4 which contains the removable desiccant cartridge 20. The air enters a space between two baskets 22, 21 in the cartridge, passes through the perforated sides thereof, is dried by the desiccant and passes out of the housing 4 into the electric heater 5. The dry, heated air then passes to duct 14 to be recirculated. The cartridge 20 has a window 40 through which an indicator can be seen which shows the degree of saturation of the desiccant so that it can be judged when the cartridge 20 is to be removed and the desiccant regenerated in a separate unit.
