Title: Improvements in or relating to depth charges and like submarine explosive bodies
IPC: F42C5/00
Filed: 1924-10-03
Abstract: 248,416. Vickers, Ltd., and Pratt, H. B. Oct. 3, 1924. Projectile fuzes. - Relates to depth charges provided with a pistol set in action by the compression of air by a piston under hydrostatic pressure, and consists mainly in the provision of means for varying the volume of air trapped for compression according to the depth at which it is desired the pistol shall function. As shown in Fig. 1, the depth charge C has a central axial tube A containing at the bottom end a primer D and fitted at the top with a casing F, which is divided into four chambers f<1>, Fig. 3, and carries the detonator e<1> and the spring striker e<4>. A valve H rotatably adjusted by a head e<6> determines the number of chambers f<1> put in communication through ports h in the valve with the space G between the primer D and the detonator e'; this setting is performed over a clicking detent e<14> and is indicated by a pointer e<12>. Before the depth charge is dropped, a safety pin d<3> is removed from a stem d projecting out from the primer D. Hydrostatic pressure can then force the primer D up the tube A, compressing the air in the space G and in the chambers f<1> in communication therewith. A rubber ring d<4> seals the joint between the primer D and the tube A. At a depth depending upon the volume of air above the primer, the primer reaches the detonator e<1>, which enters a recess d<5> in the primer. Further movement of the primer lifts a sleeve e<3> and the striker e<4> against a spring e<7> until balls e<8> escape over a shoulder e', when the striker is released and fires the detonator. In a modification, the additional air chambers are contained in a tubular casing fitted into the top end of the tube A; and interengaging projections are provided between the valve stem and the casing, which lock the striker at safe when the valve stem is set to a given position indicated as safe by the pointer thereon.

Title: Improvements in and relating to automatic electric regulators
IPC: H02P9/18
Filed: 1930-08-05
Abstract: 360,465. Automatic regulation. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London.-(Assignees of Soc. Generale de Constructions Electriques et Mecaniques Alsthom; 146, Avenue des Champs Elysees, Paris.) Aug. 5, 1930, No. 23454. Convention date, Aug. 3, 1929. [Class 38 (iv).] To reduce the effects of delay in operation of electric regulators a regulator is adjusted to respond early, that is before the regulating datum is reached, and the transmission between the regulator and the regulating apparatus is arranged so that the regulation is interrupted and the regulating apparatus is restored to its normal condition if the controlled quantity fails to reach the regulating datum within a short and regulable time. The Figure shows the arrangement for controlling the slip regulator of a flywheel machine associated with a rolling mill, in which a torque motor 1, responsive to the load current of the flywheel machine, maintains a member 3 against a stop 6 so long as the load current is below a value, p<11>, less than that, p, to which it is desired to restrict the load current. Above the value p<11> a piston 7 of a fluid dashpot 8 operates through the fluid pressure against a strong spring 18 to cause any kindof reversible servomotor to increase the slip of the flywheel machine as by closing contacts 16. The fluid leaks past a valve 12 into a space in the double bottom of the dashpot, or through a cock in a pipe connecting the spaces at each side of the piston, so long as the load current is above the value p<11>, and the spring 13 becomes fully compressed at the value p. If the load current fails to reach this value in the time determined by the adjustment of the valve 12 the pressure on the fluid ceases and the spring 18 operates the servomotor to decrease the slip of the motor.

Abstract: 1,163,162. Packaging-machines. MARYLAND CUP CORP. 23 May, 1967, No. 23900/67. Heading B8C. [Also in Division F2] A valve for an ice cream dispenser has an inlet 77, a nozzle outlet 98 and a hollow piston slide valve member 91 with a side opening 94. Upward movement of the piston closes off the inlet and at the same time applies suction to the material remaining in the nozzle so that when the nozzle is lifted from the container 22 no " tailing " takes place. The piston slides within a sleeve 85 connected to the nozzle and having a side opening 86. The arrangement is such that the piston first moves upwardly to close the inlet and apply the suction and then the sleeve starts to move upwards to cover the inlet and retract the nozzle from the container. The reciprocations of the piston and sleeve are controlled by cam followers 53, 73 connected by bars 56 and plate 51, and plate 67, respectively to the upper ends of the piston and sleeve. The followers move in slots 52, 74 in cams 37, 45 mounted on shafts 26, 31 which rotate together but are axially movable relative to one another due to rollers 33 on shaft 31 engaging within slots 32 on the enlarged end of shaft 26. The plate 51 that is connected to the bars 56 on which the follower 53 is mounted carries cam 45 so that any upward movement of the follower 53 and thus the sleeve 85 is transmitted to the cam 45 and thus to the piston 91. The containers are carried in apertures of a rotary table 20 which is rotated to move a filled container to a capping station and an empty container beneath the nozzle each time the nozzle is lifted.

In an impedance relay having an operating coil 14 energized from current terminals 12a, 12b through a variable impedance 15, the restraining winding 18 is connected directly across voltage terminals 13a, 13b, whilst the polarizing windings 16 are connected between the voltage terminal 13b and the junction between the coil 14 and the impedance whereby the windings 16 are energized by a voltage equal to that across 13a, 13b minus the drop across the impedance 15, which drop is proportional to the line current. The arrangement has the offset characteristic denoted by circle F, Fig. 5, the degree of offset being adjustable by the impedance, but this adjustment does not affect the " reach." The windings 14, 16, 18 are arranged on a 4-pole core 11a . . . 11d to influence an armature 10. A capacitor 17 forms a resonant circuit with the windings 16 to maintain a transient flux should the voltage signal fall to zero. In a modified arrangement (Fig. 6, not shown), the impedance is replaced by the primary of a transformer, the secondary (shunted by a variable resistance) being connected in the circuit of the windings 16. In a modified form of Fig. 6 (Fig. 7, not shown) the transformer core is formed by the relay core limb 11a, the winding 14 serving as the primary and the limb having a further winding serving as the secondary and connected to the windings 16.
