Abstract: 867,344. Measuring electrically. STANDARD TELEPHONES & CABLES Ltd. Jan. 12, 1959, No. 1031/59. Class 40 (1). In a system for transmitting the readings of a synchroscope, the alternating current developed in coil 12, whose alignment relative to the magnetic field produced by A.C. in coil 5 is controlled by the indicator of the synchroscope, is rectified and applied to a device 7 which generates impulses at a frequency proportional to the amplitude of the applied current, a suitable device being described in Specification 629,254. The impulses are then applied, via signalling channel 8 to a device 9 which delivers an output current proportional to the frequency of the applied pulses, e.g. the device described in Specification 629,245. The output current of this device is fed to a milliammeter 10 the reading of which is a function of the phase difference between the two inputs, 1 and 2 of the synchroscope.

Title: Apparatus for the Manufacture of Styluses for Sound Reproducing Machines.
Inventor: MOYER WILLIAM WALTON
IPC: B21G3/00
Filed: 1918-01-21
Abstract: 119,786. Moyer, W. W. Jan. 21, 1918. Forging needles.-Styli for talking-machine records are made by inserting a fine tungsten wire 173, Fig. 13, into a hole in the end of a metal shank 170 and then swaging the end to cause it to grip the wire. The shanks are fed from a detachable shoot 96, closed by a spring-pressed lever 98, Fig. 7, by means of a bar 90 having a thin tongue 93 to separate the lowest two blanks. The bar 90 carries the blank till it falls into a recess 114 t in a slide 62 and there holds it. The ejector fork 109 is moved down into grooves in the slide 62, Fig. 5, before the shank reaches the recess. The slide 62 then moves the shank till it enters the die 76, and the tungsten wire 173 is fed into the hole 172 through an adjustable friction device 160 by a spring gripper 145 on a lever 136. A' spring hammer 52 then strikes the back of the slide 62 to swage the end, and a shear-blade 149, Fig. 16, moves down to sever a short length from the wire. The slide 62 then returns and the slide 90 is withdrawn, allowing the fork 109 to be actuated by a spring 115, Fig. 7, to throw the stylus into a receptacle. The various movements are obtained from a clutch member 9, Fig. 6, feathered to slide on a shaft 4 which is constantly driven by a motor 8, Fig. 2. The member 9 is pressed by a spring 11 to engage and drive the clutch member 12 loose on a shaft 13, but twice during every revolution it is withdrawn by a fixed bowl 20 engaging the cams 18. While the member 12 is being driven, the cam 83 moves the lever 87, against a spring 86, thereby advancing the slide 90. The projection 119, Figs. 2 and 6, on the lever 87 also operates the lever 123 to set the ejector 109 against the action of the spring 115. Then a pin 49 on the member 12 engages the face 50 of a lever 23 rigid on the shaft 13 which is thus rotated against the action of a spring 32, Fig. 5, connected to the lever 23, the cam face 128 of which actuates the levers 129, 136 to feed the wire. A cam 43, Figs. 1 and 6, on the shaft 13 first moves the hammer 52 against the spring 59 by means of engaging projections 44, 61, and the projection 63 allows the lever 64 to rise under the action of a, spring 66, Fig. 1, thereby causing the arm 69, on their common shaft 65, to allow the springs 72, Fig. 5, to move the slide 62 towards die 76. Then the projection 159 operates the shear-blade 149 through lever 156 and link 152, and finally the projection 44 releases the hammer 52 which strikes the slide 62. After this, the clutch member 9 is withdrawn and the spring 32 rapidly returns the lever 23, shaft 13 &c., the projection 44, by reason of an inclined back 48 and spring support 43<1>, Fig. 1, yielding and passing under the projection 61 and the projection 63 withdrawing the slide 62. The slide 90, shear-blade 49, and ejector 109 are returned by their "springs."

Abstract: 970,833. Recovering heavy density liquid in solid classification processes. BAKER PERKINS Ltd. Jan. 14, 1963, No. 1621/63. Addition to 969,223. Heading B2H.  - Relates to the parent Specification in this Division which deals with recovery of heavy density separating liquid from entrained solid matter which is obtained as a sediment and a floated fraction respectively in a sink and float process.. The heavy density liquid and entrained matter are thoroughly mixed with water and allowed to stratify into an upper aqueous phase above a lower heavy density liquid phase which is allowed to remain quiet in regions near the interface whilst the upper phase is agitated near the liquid interface to free the heavy density liquid of solid matter. The present invention is characterized in that the means of agitation is by one or more jets of water directed into the upper phase in or near the interface. A heavy liquid, such as tetrabromoethane, is mixed with water by agitators 9, 10 in a vessel 1 and flows down a tube 4 into a separating vessel 2 fitted with a stirrer 11.  Air vents are provided at 16 and 17. The liquids separate into upper and lower phases in the vessel 2 forming an interface at 22 on to which water from an annular chamber 24 issues through a ring of inclined vanes 25 as jets ; solid material and water overflow into a circumferential launder 33 and are pumped to cyclones 39 which separate the material from the water. The heavy liquid is siphoned off at 29. The water supplied for the jets is freed from air by bends 28 and 40 in the supply pipe 23 and air valves at 26 to avoid frothing. A sight-glass for viewing the interface is provided at 32. Surface active agents may be added to stabilize the interface.
