Title: Improvements in or relating to pistols, such as are used for slaughtering purposes
IPC: A22B3/02
Filed: 1919-02-17
Abstract: 139,284. Accles, J. G. Feb. 17, 1919. Breech actions, movable-barrel, other than dropdown.-Relates to slaughtering-pistols of the captive-bolt type, and consists in providing (1) a firing-pin adapted to be placed at half-cock when the barrel catch is released, (2) slip-lock firing- mechanism, (3) a pivotal bayonet-joint connexion between the barrel and the frame, (4) a hollow handle containing lubricant for the barrel, and (5) a frame with a slidable rear closure plate. In the form shown, the barrel a is secured to the frame b by a bayonet-jointed pivot t, and is locked in the closed position by a spring bolt e operable by a thumb-piece u. When this bolt is retracted, the barrel may be swung to one side for loading, and the empty case is ejected. A releasable stop on the frame limits the swing of the barrel, so that it may not be accidentally detached at the joint t. On retraction of the bolt e, a projection i engages a lug j on the firing-pin c and retracts this to its half-cock position, in which the lug k engages the bent l of the sear f, which is pivoted to a slidable spring-bolt g. On pulling the slidable trigger h, the bolt g is forced to the rear until an inclined surface n on the sear f strikes a stop o. The sear is thereby turned down, and the firing- pin released to fire the cartridge. The handle is hollow and contains lubricant adapted to be forced through a duct z into the barrel when a piston v riding on a screw w is advanced by rotating a winged nut x. The frame b is closed at the rear by a sliclable plate q.

Patent GB-415092-A (GB)
Title: Improvements in electrical power systems for mechanically propelled vehicles and other purposes
IPC: H02P9/00
Filed: 1933-02-10
Abstract: 415,092. Systems for transmitting mechanical power. CORBRIDGE, C., 7, Carlton Avenue, Old Trafford, Manchester, and ASSOCIATED ELECTRICAL INDUSTRIES, Ltd., Crown House, Aldwych, London. Feb. 10, 1933, No. 4181. [Class 38 (iv).] In an electrical power system wherein power is transmitted from a prime mover to a load by means of an electric generator 1 and motor 2, the generator 1 is provided with a self-excited field winding 9, a separately excited winding 4 and a reverse series field winding 10, and contactor means are provided so that when the load falls below a predetermined value the separate excitation and the effective ampÞre turns of the series field winding 10 are increased by determined. amounts to maintain the prime mover output substantially constant. The separately excited winding 4 is fed by an exciting machine 3 with a shunt field coil 7 and voltage regulator 8, and the excitation is increased by short circuiting a resistance 5 by a contactor switch 6. At the same time, the ampere turns of the series winding 10 are increased by opening a contactor switch 12 to cut out the paralleled resistance 11. The motor 2 is provided with a series field winding 13 shunted by a resistance 14 and switch 15, and alternatively to opening contactor switch 12, the ampÞre turns in the winding 10 may be increased by closing the switch 15. This lowers the back electromotive force of the motor and increases the current taken from the generator. Other suitable means of increasing the effective ampere turns of the windings may be used.

Title: Improvements in or relating to parametic amplifiers
IPC: H01J25/49
Filed: 1960-02-05
Abstract: 932,271. Space-charge wave tubes. SIEMENS & HALSKE A.G. Feb: 5, 1960 [Feb. 6, 1959], No. 4196/60. Class 39 (1). A parametric amplifier comprises an electron beam generating means and at least two parallel delay lines having the same delay as each other, wherein projecting portions of the delay lines form a series of capacitive couplings distributed along the length of, and between the delay lines, wherein one or more electron beams are passed through the space between the projecting portions and wherein means are provided for producing velocity or deflection modulation of the electron beam or beams in the space between the portions forming the capacitive couplings. Variable capacity couplings between the delay lines are thus produced by the one or more electron beams. Two ridged loaded waveguides for the signal and load respectively may be coupled together (forward wave-structure) or two waveguides 116, 117, Fig. 4, having two open sides and loading members 120, 121; 124, 125 are coupled together (backward wave structure) capacitively or one line supports a forward and the other a backward wave, and the electron beams travel perpendicular to the longitudinal axis of the delay lines. In Fig. 11, a plurality of electron beams go respectively through capacitors 41, 42, 43 of a double delay line. Pre-velocity modulation is effected by delay line 51 and maximum bunching occurs at capacitors 41, 42, 43. The pre-velocity modulation may be replaced by deflection. The plurality of electron beams may be replaced by a single electron beam which goes parallel to the double delay line. Magnetic focusing is used. Dielectric members 52 can be pushed in and out to give fine adjustment of the phase velocity. Pump energy can be generated in the tube itself by feeding back energy from cavities 53, 54, 55 to delay line 51. To get a pump frequency of nf, n beams each modulated with frequency f are passed with a suitable phase displacement successively through a single capacitor 41, 42 or 43, an example of 3 beams being described with reference to Figs. 12 and 13 (not shown), the pre-delay line may be a helix, Fig. 13 (not shown). In a deflection control tube, Fig. 14, stated to produce frequency multiplication a deflection grid comprising two sets of rods is provided and the capacitors 72 are arranged behind apertures in a screen 71. In a modification, Fig. 15, not shown, a beam is deflected or velocity modulated and then passed across a plurality of capacitors. Feedback from the output to the velocity modulation means may be used as in Fig. 11. In a crossed-field device, Fig. 17, the beam is predeflected by plates 98. In all forms the pump frequency can be greater or less than the signal frequency.

Abstract: 380,094. Discharge apparatus. BRETTMON; J., 226, Rue de Rivoli, Paris. March 12, 1931, No. 4473. [Class 39 (i).] One terminal of a voltage source is connected to a main electrode p, Fig. 1, and the other terminal to one of two auxiliary electrodes e<1>, e<2> of pointed form so spaced that a voltage lower than that applied to the electrode p produces an auxiliary glow discharge between the electrodes e<1>, e<2>.
