Abstract: 638,826. Granulating metals. AMERICAN FOUNDRY EQUIPMENT CO. Oct. 30, 1946, No. 32206. Convention date, Nov 1, 1945. [Class 82(ii)] In the making of metal particles, a pulsating blast of dispersed liquid particles is directed at high velocity against a molten stream of the metal. The apparatus may be employed in an inert or reducing atmosphere. As shown, molten metal from a tiltable furnace 10 is supplied by an adjustable trough 11 into a metering dish 12 having a comparatively wide and thin rectangular orifice 26 surrounded by a U- shaped wind guard 57, the trough 11, dish 12 and orifice 26 being made of refractorylined metal. A pump supplies water and/ or oil to a blast wheel 13, similar to that described in Specification 441,466, [Group XXVI], and comprising substantially radial blades 39 removably mounted in recesses in side plates one of which carries a central stationary but adjustable control cage 41. The circumferential wall of the latter has a discharge opening 43 making a close fit with the inner edges of the blades 39 which are partially surrounded by a shroud 54. The blades deliver the liquid in a rapid succession of ribbons or layers 60 forming a substantially tangential downwardly-directed and slightly flaring arc 15 and striking the molten metal stream 23 at an acute angle close to the orifice 26 to disintegrate it into particles 23. The Specification as open to inspection under Sect. 91 states also that the orifice 26 may be of square cross-section. This subject - matter does not appear in the Specification as accepted.

Title: Improvements in matrix read-out devices
IPC: G11C11/06
Filed: 1955-11-11
Abstract: 780,689. Electric digital-data-storage apparatus. INTERNATIONAL BUSINESS MACH. INES CORPORATION. Nov. 11, 1955 [Nov. 16, 1954], No. 32288/55. Class 106 (1). [Also . in Group XXXIX] A magnetic core storage matrix of the type wherein read-out is effected by coincident current technique, includes means for energizing separately at least one read-out line within a short time of a read-out operation and generating a threshold level signal resulting from cores half-selected, and means for applying said threshold level signal to the output obtained upon read-out to obtain a resultant output signal substantially unaffected by the outputs of half-selected cores. The preferred embodiment employs a 10 x m X n three dimensional matrix having 10 X-windings, winding Xi passing through every core having a co-ordinate Xi, m Y-windings and n V-windings, winding Vk being connected between earth and one control grid of a double triode I, Fig. 4, and uses a seven-period read-out cycle, Fig. 5. In the first period, T1, an X read-out pulse is applied to the matrix inducing a signal (a) in the winding Vk which is amplified and inverted and passed via the right-hand cathode, (b) of tube I to charge a condenser 17, diode 51 being blocked. In the second period, T2, a further X pulse is applied, but of opposite polarity, restoring the matrix to its original condition just prior to the application of the first X pulse. During this second period the potential across the condenser 17 remains constant because diode 16 is blocked. In the third period, T3, a Y pulse is applied and it is assumed that the output produced by Y-half-selection is less than was produced by X-half-selection. In the fourth period a further X-pulse is applied causing reading proper, the read-out signal (assumed to be a 1) induced in winding Vk having subtracted from it the signal due to half-selections previously stored on condenser 17 and the difference being applied to a triode II to give a resultant negative output-substantially free from unwanted signals-at a terminal 25. During the remaining three periods the bit read-out is re-read in, and the circuit is re-set triodes III, IV and VI being controlled by synchronizing pulses. In a second embodiment (Figs. 6 and 7, not shown), read-out proper is effected before the output due to half-selection is sampled. A suitable pulse generator (Fig. 3, not shown) is described for driving the X and Y windings.

Title: Electric fences and voltage generators therefor
IPC: H05C1/04
Filed: 1971-07-09
Abstract: 1395498 Supply systems for electric fences P M ADORIAN and L P LEARNEY 7 July 1972 [9 July 1971] 32341/71 Heading H2H [Also in Division H3] A voltage generator for an electric fence 8-10 comprises a step up transformer 2, 3, a low frequency pulse generator 11 and a high frequency pulse generator 12, the pulse generators enabling bursts of D.C. pulses to be supplied to the transformer primary winding. Each low frequency pulse gates open a transistor 13 to supply the high frequency pulses via an emitterfollower transistor 14 to a transistor 15. A capacitor 16 charged from a D.C. supply terminal 7 is therefore discharged through the primary winding 2 each time a high frequency pulse switches on the transistor 15. The bursts of pulses are stepped up by the transformer and fed to the fence. In the absence of a load on the fence, i.e. in the absence of the fence being touched, the high voltage at the fence is detected by a winding 4 to switch on a transistor 29 thereby discharging a capacitor 32 and reducing the mark period of the low frequency pulses so that the transistor 13 is gated open for only a single high frequency pulse thereby reducing the drain on the D.C. supply. The pulse generators are supplied via a voltage stabilizer including transistors 27, 28. A modified form of the circuit for reducing the drain on the supply during no-load conditions is also described. A loud-speaker may be provided to give a warning when the fence is "on load".

Title: Safety contact device for electrically controlled lifts, particularly for hatchway and cage gates
IPC: B66B13/22
Filed: 1934-11-20
Abstract: 432,160. Looking lift and well doors. INVENTIO AKT.-GES., Hergiswil, Nidwalden, Switzerland. Nov. 20, 1934, No. 33354. Convention date, Dec. 24, 1933. [Class 78 (iii)] Safety-mechanism for well-doors of lifts is arranged so that the contacts for establishing the main starting-circuit for the lift cannot be bridged improperly when the gate or door is open. When the switch-arm B, Fig. 5, on the gate post bridges the contacts T the lift can be started, but when it bridges the contacts L a light signal is shown and starting cannot take place even if the contacts T are bridged improperly. The closing of the gate causes the bolt P to be moved to its gate-locking position, this movement also swinging the bell-crank K sufficiently to break the contact L. A shortcircuit is thus removed in a circuit including a hand-controlled device, such as a pushbutton on the cage so that by pressing the latter, the bolt R can be made to move outwards and rock the lever W, thus forcing a sliding key r inwards and releasing a system of levers whereby the arm V is moved upwards to bridge the contacts T. When the desired floor is reached, the floor switch initiates the movement by which bolt R is moved rearwardly; its coned end contacting with a projection H on the rod V and effecting a positive breaking of the contacts T, with a consequential movement of the levers to their original position. The sliding key r and associated levers are shown in detail in Fig. 1. Three levers a, b, c are loosely pivoted on the shaft g. Lever c carries a lever d pivoted thereto at and having a pin-and-slot engagement with a fixed point e. The sliding of the key r tends to swing all three levers about the pivot g, but the mounting of the lever d is such that it must rock during this process about point e and it is prevented from rocking by a spur on the lower end engaging the peripheries of the levers a, b. Thus the initial movement of the key r causes wards on its outer end to move levers a, b only by regulated amounts until slots in the periphery register with the spur on the lever d. After this, all three levers are swung simultaneously so that the angular movement of lever d is transmitted to the rod V as previously described. When the contact T is broken by the coned end of bolt R, the lever d is moved to free the levers a, b which return to their initial position under the action of springs. Since the contacts T and L are in a closed casing, the only access to which is through the sliding bolt holes, it is impossible for them to be tampered with by unauthorized bridging.
