Title: Improvements in or relating to motorcycles
IPC: F02N3/04
Filed: 1954-06-16
Abstract: 766,907. Brakes for motor-cycles. KREIDLER, A. June 16, 1954 [June 17, 1953], No. 17646/54. Classes 136(1), 136(2) and 136(3). In a motor-cycle including a pedal crankshaft 3 operatively connected through a free wheel clutch 4 to the engine crankshaft 8 and a brake adapted to actuate by foot pressure through a ratchet clutch 19-22, one pedal crank 14 is adapted optionally to be fixedly or rotatably mounted on the crankshaft 3 and to be operatively connected to the brake in either of the optical mounting conditions, whereby when the pedal crank 14 is fixedly mounted on the crankshaft 3 by a cotter pin 16 the brake acts on backpedalling and when rotatably mounted actuation of the brake is independent of the crankshaft rotation. The freewheel brake actuating clutch 19-22 comprises a clutch housing 20 and a clutch hub 19 on which a spring loaded pawl 21 is mounted for co-operal ion with a complimentary internal ratchet on the housing 20. A tension rod 23 which leads to the rear wheel brake is hinged to a lug 22 on the housing 20, Fig. 5. The clutch hub 19 is provided with serrations 24, 25 on its respective side faces for co-operation with serrations 26 on the inner face of a boss 27 on the crank 14. Pedal cranks 13, 14 are connected to the crankshaft 3 by cotters 15, 16. The cranks are of identical construction and are interchangeable. When the vehicle is to be converted into a motor-cycle, the pedals 17, 18 are converted into foot rests by unscrewing them from the ends of the cranks 13, 14 and screwing them into holes 32, 33 arranged eccentrically to the axis of the pedal cranks. The right hand cotter 16 is then removed, the crank 14 drawn off and after disconnecting the tension rod 23 the ratchet clutch 19-22 is removed. The latter is then slipped on the shaft 3 in the reverse manner and a circlip 36 is fitted. The crank 14 may then be used as a toe-brake. On removal of the cotter 16 the free wheel clutch 4 causes the crank 13 to hang vertically downwards as shown in Fig: 4. The crank 13 is used as a kick starter.

Title: Apparatus for discharging loads from aircraft
IPC: B64D1/02
Filed: 1928-06-19
Abstract: 292,513. Rohrbach Metall-Flugzeugbau Ges. June 20, 1927, [Convention date]. Dropping bombs and other articles from a height.-Relates to apparatus comprising a number of independent discharging appliances each with its own control lever, and consists mainly in the provision of means for coupling any of the levers together when desired. As shown, the levers 20, Figs. 1 and 2, are pivoted on a tube 82 on a fixed spindle 83. Each handle is connected by a member 16 to its discharging appliance (not shown), and is provided with a catch 21 controlled by a spring 89 and adapted to engage a notch 22 in a sector 23 to hold the lever in the position of rest. Each lever is in addition provided with a catch 93 adapted under the action of a spring 91 to engage a hole 94 in the tube 82. When a catch 93 is thus in engagement with the hole 94, the lever 20 is locked to the tube 82; and all levers locked to the tube 82 are simultaneously operated by action on any of them. The catch 93 is provided with a projecting tongue 95 by which the catch can be pulled away from the hole 94. The tube 82 has a slot 85, Fig. 5, which limits the movement of the tube by its engagement with a fixed stud 84; and a spring 86 between the tube 82 and the fixed spindle 83 serves to return the tube 82 to the position of rest, where the holes 94 are not in line with but in near reach of the catches 93 when the levers are in their positions of rest.

Title: Improvements in or relating to fuzes for practice projectiles
Inventor: KAISER PAUL
IPC: F42C1/08
Filed: 1965-04-27
Abstract: 1,106,789. Projectile fuzes. GEBRUDER JUNGHANS G.m.b.H. 27 April, 1965, No. 17764/65. Heading F3A. A fuze for a practice projectile to be fired from a rifled gun comprises impact-operated firing means mounted in the nose Sp of the fuze, the pressure wave generated travelling along an axial passage to operate the main firing means which is situate in the body of the fuze. Into the nose Sp is screwed a plug 48 housing a primer pellet 124 aligned with a firing pin which is supported by a striker 120 engaged by two centrifugal members 121 held together by a coil spring 122. On firing the projectile, the members 121 move apart and free the striker for operation on impact. Due to the acceleration of the projectile, striker pins 12 and a retaining cover 14 set back shearing safety pins 11 and a disc 13. The pins 12 strike primers 17, which in turn ignite delay trains 18 housed with their respective primers and firing pins in bores extending longitudinally through the wall of the fuze casing. When disc 13 is sheared, the cover 14 moves rearwardly and allows a spring 110 to expand. Segments 19 supporting the top 111a of a striker 111 then move outwards due to centrifugal force and free the striker. Striker 111 extends through a socket 42 forming part of a core 41, 40 and housing clockwork 112, through which extends a firing pin 113 aligned with the striker 111. Pivotally mounted within the core is a primer carrier 46 locked in the safe position by a latch 118 depending, from the clockwork. Centrifugal force starts the clockwork and after a certain time latch 118 releases the carrier 46, which then pivots to the armed position in which primer 117 is aligned with firing pin 113 and a relay charge 126. The fuze is then ready for operation on impact. In the meantime, carriers 43 pivot about their axles 44 until primers 114 are aligned with the delay trains 18 and relay charges 134. Thus if impact does not occur within a given time, the delays 18 ignite primers 114, which fire the relays 134 and hence charge 49 to bring about self-destruction. Should the projectile strike the target obliquely, the mass comprising the core 40, 41 and its contents and pellet 126 move forwards under their momentum against the action of spring 128 until pellet 117 hits the firing pin 113. A hammer 132 surrounding the striker 111 and supported by centrifugal weights 130, 131 may also bring about self-destruction. To equalize the pressure developed by the delays 18, a slotted sleeve 35 is introduced into each bore and a guide S surrounding each striker 12 has a certain amount of play, so that gas can escape to an annular groove 37a in a cover cap 37 overlying each bore.

Title: Resonant quadrupole pump structure for an electron-beam parametric amplifier
IPC: H01J25/49
Filed: 1963-05-07
Abstract: 980,149. Electron beam parametric amplifiers; resonant structures. ZENITH RADIO CORPORATION. May 7, 1963 [May 18, 1962], No. 17942/63. Headings H1D and H1W. A resonant quadrupole pump structure for use in an electron beam parametric amplifier has a pump signal source 19 of a predetermined frequency, the structure comprising four similar conductors 25, 26, 27, 28 constituting the principal distributed capacitance of the structure and enclosing a path for the electron beam, at least one conductive disc 30 having four fingers 33a, 33b, 33c, 33d, directed radially inward and circumscribing the conductors with the fingers of the disc conductively and mechanically connected respectively to the conductors, and constituting an inductance for establishing with the capacitance a resonant frequency for the pump structure corresponding to the predetermined frequency, and means 35, 36, 37 adapted to couple space-opposed pairs of the conductors to opposite-polarity terminals of the pump signal source. Each disc has four cut-out portions 32a, 32b, 32c, 32d simulating singleturn inductors which terminate in the inwardlydirected finger portions, and the pump energy may be connected by two conductors 38, 39 to one of the portions. In the degenerate mode of operation the conductors are elongated straight parallel rods, and the input and output couplers are of the Cuccia. type; alternatively, a twisted structure, Fig. 6 (not shown), may be used, the frequency of the pump source being either above or below twice the signal frequency, depending on the direction of twist and the input and output couplers may be distributed structures such as transmission lines. The structure is tuned by varying the distance between flexible electrodes 40, 41 which alters the capacitance of the structure. If the length of the quadrupole is very small compared to one-quarter of the free space wavelength corresponding to the pump frequency, the pump source may be connected at any location along the length of the structure, e.g. one disc 30 may be used positioned at the centre (Fig. 4, not shown). As the length approaches a quarter wavelength, voltage nodes are avoided by positioning two discs at either end of the structure, as shown in Fig. 2. In the case where the length is in excess of a halfwavelength, discs are placed so that there are no nodes along the quadrupole, being positioned less than half a wavelength apart. The structure is preferably supported by axially extending rods (not shown) passing through holes 42 cut in the discs; the couplers 14, 16 and the electrodes of the gun 10 may also be supported from the rods. A longitudinal magnetic field 20 is provided. Specification 929,015 is referred to.
