Title: Improvements in or relating to electric signal responsive equipment
Inventor: HELLIER WILLIAM HERBERT MORGAN
IPC: H02J13/00
Filed: 1952-03-14
Abstract: 715,651. Actuation of switches. STANDARD TELEPHONES & CABLES, Ltd. March 14, 1952, No. 6736/52. Class 38(5) A switch adapted to respond to two suitably spaced D.C. impulses superposed on an A.C. line comprises a contact 18, Fig. 8A, on a spring arm 21 fixed to a rocker 22 pivoted at 51 and controlled by a bowed spring 32. The switch is actuated by one of two cams 12a, 12b on a motor-driven wheel 5 which is caused to make one revolution on receipt of the first impulse. Actuation only occurs however when the second impulse causes a detent 48 to project from the face of the rocker 22 between the wings of the cam as shown in Fig. 8A. As the cam continues to rotate its trailing edge will then operate the switch, the bowed spring 32 snapping into its other position. Should the impulse occur at any other time the switch will not be operated, since, even if the impulse is long enough for the detent to be engaged it will be engaged by the leading edge of the cam and be moved slightly in the other direction. The detent 48 is normally flush with the face of the rocker 22 being biased into this position by a spring on the other side of the rocker, Fig. 7. An impulse energizes an electromagnet R which attracts its armature 41 and operates a lever 40 to depress the detent and cause it to project at the other side, irrespective of the position of the rocker 22. The armature also operates contacts r<SP>1</SP> which complete the circuit to the motor at the first impulse, the motor circuit being thereafter maintained for the revolution by contacts 16, 17 operated by a cam on the wheel 5. Specifications 495,057 and 528,790, [both in Group XXXVIII], are referred to.

Title: Improvements relating to telephone instruments
IPC: H04M1/08
Filed: 1929-03-04
Abstract: 326,655. Dunlop, S., (Fuld & Co. Telephon. und Telegraphenwerke Akt.-Ges., H.). March 4, 1929. Desk and table sets; wall sets.-A subscriber's telephone set in which the microtelephone is supported horizontally has all the components required for its operation arranged on a base-plate so that the casing may be removed and replaced without disturbing any of the components. The base plate 11, Fig. 1, runs parallel with the bottom and back wall of the casing, and has stamped and bent out lugs which support the components. Among these are the forks 12 for supporting the microtelephone, and the dial 33; the dial 33 is pivoted at 35 to enable the casing 10 to be lifted off vertically, and is supported solely by the casing. The base plate is provided with openings 46, Fig. 4, which serve for passage of the sound of the bells 45 and for suspending the instrument when used as a wall set. In this latter case the dial is set round through 180‹ and is re-pivoted, Fig. 4, and the microtelephone 62 is supported by forks which actuate the releasing switch horizontally instead of vertically. In the desk instrument, Fig. 1, the microtelephone is supported by two forks 12, provided with guide pins 13 passing through holes in the plate 11. Each fork has a longer pin 15, controlled by springs 19, and actuating the reversing contacts 16. Each fork 12 is independently movable 'so that the line is switched off even if the microtelephone is replaced on one fork only. In the wall set, Fig. 4, the forks are replaced by supporting members 53 provided with hooks 54, and the actuating rods 57, controlled by springs 58, bear against a stop 56. A guide 61 constrains the movement of the support 53 to be rotational about the hook 54. A fixed member 63, Fig. 5, provided with a slider 66, which actuates the switch releasing rods 67 when the microtelephone is used, may replace the device employed in the member 53 in Fig. 4. A further modification, Fig. 6, has the contact reversing rod 75 pivoted on the slider 72, Fig. 7, which is in turn pivoted at 71 to the member 70.
Patent GB-625880-A (GB)
Title: Device for reducing erosion in a gun barrel by cooling the expanding explosion gases
IPC: F41A13/04
Filed: 1947-03-13
Abstract: 625,880. Cooling guns. ETUDES ET CONTROLES INDUSTRIELS. March 13, 1947, No. 6989. Convention date, Feb. 12, 1940. [Class 92 (ii)] To reduce erosion in a gun barrel a cooling liquid is injected into points along the barrel to cool the explosion gases, injection commencing before the projectile leaves the barrel. In the form shown in Fig. 2, recoil of the gun carries back a piston 11 in a fixed cylinder 10, forcing cooling liquid from the space 13 through the telescopic tube 15 into the barrel through ports 1, 2 and 3 in the barrel wall. Control of the amount of fluid injected at any instant in the recoil of the gun is effected by actuating a needle valve 19 in the tube 15 by a cam 40 carried by the gun. The space 13 is refilled with cooling liquid by induction through a non- return valve 21 when the gun is run out. In a modification (Fig. 3, not shown), the piston carries a needle of varying diameter which restricts the neck of the conduit 15 and thus varies the rate of injection. The cylinder may be carried by the gun and the piston fixed when the fluid will be supplied to the cylinder through a flexible conduit. In one embodiment (Fig. 6, not shown), the piston is replaced by a heavy weight which exerts pressure on the fluid by virtue of its inertia. Fig. 4 illustrates a system in which the telescopic tube is replaced by a hollow piston-rod 12 which feeds the coolant to the bore. Control of the rate of injection of the coolant is effected by a valve box 33 carried by an extension 12<SP>1</SP> of the pistonrod. This box on moving longitudinally is caused to rotate by a fixed feather 34 which engages in a slot in it and the piston-rod 12 fixed to the box is caused to rotate on its own axis, thereby varying the passage area through valve faces X, Y and X<SP>1</SP>, Y', Fig. 5. A similar valve at another extension of this rod permits the escape of excess fluid which cannot pass to the bore. A device for spraying liquid on to the gases leaving the muzzle is also described.

Title: Improvements in or relating to apparatus for supplying air to the carburettors of internal combustion engines
IPC: F02M31/06
Filed: 1927-03-14
Abstract: 292,229. Ricardo, H. R. March 14, 1927. Spray carburettors.-The temperature of the air supplied to a carburettor is varied substantially in inverse proportion to the torque of the engine. The temperature control may be effected directly from the throttle lever or more conveniently, in accordance with the pressur in the induction pipe but in either case a dashpot or like device is provided to introduce a time lag in such a manner that the extent of the lag will be reduced automatically as the temperature of the engine rises. Air is supplied to the inlet A<1> of the carburettor A from a casing C having inlets C<2> for cold air and inlets C<3> for air heated in a casing F<1> around the exhaust pipe A<2>, or by other means. Formed integrally with the upper cover D of the is a cylinder D<2> containing a piston G which is subjected, at its upper face, through a pipe O to the pressure existing in the induction pipe B. The lower cover E comprises a dashpot cylinder E<4> the piston E<5> in which is loaded by a spring J and is connected to the piston G by a, rod H which carries a valve N having a disc-like portion N<2> and a coned portion N<1>. The hot-air pipe F is connected to or integral with a ring F<3> engaging walls C<3>, C<6> and forming a chamber C<4>. The cold air passes through the throat of a substantially Venturi-shaped member L, and the hot air through the throat M<1> of a member M. The cylinder E<4> is filled with a liquid which becomes less viscous as its temperature increases. With closed throttle and therefore small engine torque, the suction through pipe O is large, the piston G is raised, the cold air is cut off by disc N<2> and heated air only is admitted through M<1>. With throttle fully open and torque at a maximum, the cone N' closes hot-air inlet M<1>, and the throat in cold-air inlet L is fully open. With intermediate throttle positions, varying proportions of both hot and cold air are admitted. The dashpot prevents a too sudden reduction of air temperature upon sudden opening of the throttle, and the throat M<1> at the same time causes an increase of depression at the fuel orifice and a somewhat richer mixture to be supplied. The rod H may, alternatively, be connected through resilient means with the throttle valve.
