Title: Improvements in or relating to launching or ejecting tubes for automobile torpedoes
IPC: F41F3/08
Filed: 1925-06-11
Abstract: 256,741. Whitehead Torpedo Co., Ltd., and Jones, A. E. June 11, 1925. Launching torpedoes.-The front door B, Fig. 1, of a torpedo tube A is opened by a piston F, which, when the door is fully open, uncovers a port f<2>, allowing compressed air to pass from the cylinder F<2> of the piston F to the tube A for ejecting the torpedo. The launching gear is set in action by means of an electromagnet E<4>. When the circuit of this electromagnet is closed by the firing key, it deflects its armature E<3> from a lever E<2> which is moved by a spring and pulls a toggle mechanism e, e<2> out of the locking position shown. An escape valve E is thus released and causes the opening of the launching valve D, which admits compressed air to the front face of the piston F. This piston is connected to a floating lever F' pivoted at its ends to rods H<1>, G<1>. The first part of the rearward movement of the piston causes a rearward movement of the rod G', which rocks a bell crank G and turns a ring B<2>, unlocking the front door B. At the same time the rod G<1> opens a valve g<4> to equalize the pressure inside the tube with the external pressure, raises a stop bolt g<3>, depresses a starting bolt g<2>, and bars the path of a lug C<2> on the locking ring C' of the back door C thereby preventing the accidental opening of this door. When the front door is fully unlocked, a stop g<x> on the rod G<1> abuts against a fixed stop a<x> and the further rearward movement of the piston carries the rod H<1> rearward; this shuts a drain cock h<1>, Fig. 5, and opens the front door B about its hinge b by means of a bell crank H and a link h. When the door is open, the piston F uncovers the port f<2> as aforesaid. After the torpedo has been discharged, compressed air is admitted behind the piston F by a hand-operated valve F<3> and the parts are returned to the original position. The back door may now be opened for the insertion of a fresh torpedo. The opening of this door cocks the lever E<2> and toggle mechanism e, e<2> by means of a fork j at the front end of a rod J connected to a bell crank J<1> rocked by the unlocking rotation of the ring C<1>. While the door is open, the fork j locks the armature E<6> against accidental operation, and movement of the rod G<1> is prevented by the lug C<2>.

Abstract: 888,825. Feeding records in punching machines. INTERNATIONAL BUSINESS MACHINES CORPORATION. May 2, 1960 [May 4, 1959], No. 15289/60. Class 31 (2). [Also in Group XVI] A record feeding device for intermittently feeding a record past a punching station 118 comprises an outer disc 3, Fig. 1, having a flanged periphery 4, an inner disc 2 mounted for eccentric rotation against the inner face of said flanged periphery and driving a drum 120, Fig. 4, which supports and steps the record past the punches of the punching station 118. The records are first put on surface 111, Fig. 4, and when a pawl 110 is released they are fed by rollers 113, 112 on to the drum 120. Here they are gripped by an endless belt 121 guided around the drum 120 by rollers 122, 123, 124. The drive by the inner eccentrically mounted disc 3 effects an intermittent hypocycloid movement so that the record is substantially stationary for punching. After punching, the record is ejected by a rapid feed comprising a cone 138, Fig. 5, engaging the outer surface of the flanged periphery 4. The cone is driven by a pulley and belt and is shifted axially by an electromagnet 146. When the cone is returned a brake 137 engages the periphery 4.

Filed: 1924-06-26
Abstract: 224,827. Western Electric Co., Ltd., (Western Electric Co., Inc.). June 26, 1924. Solenoids.-The magnetic material of a continuously loaded conductor is demagnetized by passing the conductor through a localized magnetic field. The conductor is passed lengthwise through a field, produced by an alternating- current in the coil 17, which is sufficiently strong to saturate the loading material. The coil is wound in sections, the first two and the last four sections being in parallel, and the two groups are connected in series. Thus, the magnetic flux m the loading material is gradually reduced in magnitude while rapidly alternating in direction. Specifications 184,774, 184,782, and 188.688, [all in Class 36, Electricity, Conducting &c.], are referred to.

Title: Improvements in or relating to pulse-selecting circuit arrangements
IPC: G01R29/027
Filed: 1945-06-21
Abstract: 593,990. Pulse modulation. WEBLEY, R. S. June 21, 1945, No. 15908. [Class 40 (v)] A pulse-selecting circuit arrangement comprises means to produce shortened pulses from applied pulses of greater than a pre-determined duration, and means to resonate with those shortened pulses having durations substantially equal to half the natural period of the resonant means, an amplitude discriminator being provided to select from the output of the resonant circuit, voltage excursions which exceed a pre-determined amplitude. The invention may be used to reduce the effects of jamming and interference in pulse-echo system or to select line and frame synchronizing pulses in a television system. In the circuit described the capacity-resistance input circuit K1, Rl to the normally conducting valve V1 is of such a time-constant as to reject pulses of duration much longer than the required pulses, D.C. restoration being effected by using the diode characteristics of the control gridcathode space of valve V1. On reception of negative going pulses, curve (a), Fig. 2, V1 cuts off and the anode voltage rises exponentially to a limiting value set by diodes D1, D2, curve (b), if the pulse is of sufficient duration. The grid of valve V2 is connected to the anode of V1, so that V2 conducts when the anode voltage of V1 rises above a value stabilized by the gas discharge tube GD in the cathode circuit of V2, to produce the current pulses, curve (c), in its anode circuit. The anode circuit comprises a damped resonant circuit LC, the capacity being strong and/or self-capacity, and the resistance R3 being adjusted to give an output voltage waveform of the form shown in curve (d) due to shock excitation by the current pulses. The maximum positive excursion of the voltage at the anode of V2, due to desired pulses of correct duration is sufficient to overcome the cut-off bias v applied to valve V3 to produce the current pulse, curve (e) through this valve. The anode voltage waveform of V3, curve (f), is a lengthened pulse x given by a high anode load.

Abstract: 1,002,257. Transfers. E. PEREIRABORRAJO. April 26, 1962 [May 1, 1961], No. 15999/62. Heading B6C. A transfer for decorating pottery &c. is printed with an ink comprising a vitrifiable pigment in a vehicle consisting of a mixture of waxes and resins formulated so that it is fusible between ambient temperature and 150‹ C. and solidifies again on cooling, and so that at the firing temperature the change from solid to liquid to gaseous state occurs substantially simultaneously. The paper or other backing is first coated with a water-soluble gum and then printed with the ink which is liquefied by heating for this purpose. Before or after printing, a coating of a water-insoluble film may be applied so as to form a support for the design after the paper and water-soluble coating have been removed during the application of the design to an article. In examples given, beeswax, paraffin wax, carnauba wax, spermaceti and stearin, and WW resin, venetian turpentine and labdanum are employed as the waxes and resins. For the water-insoluble film, chlorinated caoutchouc, cellulose, synthetic latex, polyester or vinyl resins dissolved in organic solvents may be used.
