Title: Improvements in or relating to electric discharge tubes
IPC: H01J25/32
Filed: 1951-07-03
Abstract: 701,308. Velocity-modulated tubes. PHILIPS ELECTRICAL INDUSTRIES, Ltd. July 3, 1951 [July 6, 1950], No. 15745/51. Class 39(1) In an electron discharge tube in which an electron beam interacts with standing waves on a Lecher resonator 3, Fig. 1, so as to become velocity modulated, each of the mutually external parallel conductors 5 of the resonator has a gap 7 located at, or not further away than #/10 from, a voltage antinode, the parts of the conductors remote from the gaps being secured to an insulating body, such as the tube envelope, which is not directly heated by the discharge. The interruption allows for thermal expansion of the resonator parts, which is large relatively to that of the insulating body, and so prevents undesired frequency drift. The tube may contain more than one Lecher resonator and more than one electron beam may be used. As shown the resonator comprises two strips 5 in a rectangular box 3 which are apertured at 13 for passage of the beam and interrupted at 6, 7. The parts secured to the envelope are strips 5, supporting disc 2 and leads 8. The device functions as a brake field oscillator, electrode 11 being at cathode potential and electrode 12 still more negative. 10 is an auxiliary focusing electrode, the main focusing being effected by a magnetic field,

Title: Improvements in projectiles to be launched by means of a firearm and including an auxiliary propulsion motor
IPC: F42B30/04
Filed: 1960-05-04
Abstract: 872,588. Ammunition. BREVETS-AEROMECANIQUES S. A. May 4, 1960 [May 21, 1959], No. 15788/60. Class 9(1). A projectile 2 launched from a firearm barrel 1 is provided with an auxiliary propulsion jet motor 4 characterized in that the said motor is axially slidable with respect to the projectile between a front abutment 9 and a rear abutment 7, both carried by the projectile, in such a manner that only the projectile is initially accelerated when the firearm is fired and thus is the only part to give rise to recoil. The propellant is housed in an annular chamber 5 closed at the front and having at least one annular exhaust nozzle 6 at the rear. The rear abutment 7, on the tubular extension 3 of the projectile, limits the rearward movement of an abutment 8 that projects inwardly from the chamber 5, though preferably the thrust of the motor prevents these abutments from coming into contact. In operation, when the firearm is fired the powder gases thrust the projectile forward, a conduit 11 in the projectile extension 3 soon becomes aligned with a conduit 12 in the motor housing, the gases thereby ignite the propellant and the motor comes to bear on the abutment 9 of the projectile and transmits its thrust thereto. If the propellant fails to ignite, when the projectile has moved a distance Y the firearm and extension 3 are no longer gastight, due to an increase in the internal diameter of the latter, and the gases escape, thereby preventing a sudden increase of the recoil when the motor is drawn forward by the projectile. The projectile cannot burst until the abutment 10 of the motor depresses a plunger 14 in the projectile, which operates the electric fuze. Stabilizing tail fins 15 are mounted on the motor and a gas deflecting shield 16 is mounted on the firearm barrel 1.

Filed: 1954-10-01
Abstract: 783,874. Typewriters. BURROUGHS CORPORATION. Oct. 1, 1954, No. 16499/55. Divided out of 783,869. Class 100(4) Differentially settable type bars 149 of an accounting machine vary in their spacing from a common impression hammer 44, according to their individual settings, and means are provided for aligning them at equal distances from the hammer prior to the printing stroke, in order that a uniform record shall result. The invention is applied to the machine described in Specification 783,869. The type bars print amounts during calculating operations and normally lie below the printing line to give clearance for conventional type levers with which the machine is also provided. The printing hammer normally overlies the unset type bars and incorporates the type lever guide 43. The type bars are pivoted at their lower ends to individual slides 151 engaged by bell-cranks 154 by which they are raised into differentially set position, Fig. 3, at the commencement of an operating cycle, the hammer 44 being retracted in preparation for the printing stroke. A comb 204 guides the type bars in their upward movement and this results in the type bars falling rearwardly and out of transverse alignment. Re-alignment of the raised type bars is effected, according to the invention, by imparting a forward movement to the comb 204. For this purpose the comb is mounted to rock about the edges of a pair of plates 207 against which it is held by a spring (not shown). An arm 221 extends downwardly from the comb and is connected by a link 224 with a lever 227 pivoted at 228. A cyclic actuating member 169 of the calculating mechanism is adapted to rock the lever 227 which rocks the comb 204 counterclockwise to align the set type bars 149 in a vertical plane prior to actuation of the hammer 44. If an excessive thickness of a record material is introduced between the type bars and platen 58, the comb 204 lifts off the pivot edges of the plates 207 and a spring 234, interposed between a pivoted arm 230 through which the member 169 drives'the lever 227, yields.
