Title: Improvements in Radio Signalling Apparatus.
IPC: H04B1/12
Filed: 1919-05-28
Abstract: 129,625. Marconi's Wireless Telegraph Co., (Assignees of Weagant, R. A., and Waterman, F. N.). July 12, 1918, [Convention date]. Directive wireless signalling; aerials.-In a wireless receiving system, atmospherics are eliminated by employing a plurality of vertical directive loop aerials of extreme length compared with their height, connected by short leads to an apparatus by which currents due to atmospherics are balanced out, while currents due to signals produce a cumulative effect. The distance between the central points of the aerials is of the order of half a wave length, and the capacity and inductance of the aerials per unit of length is constant or uniformly graded, so that no refiecting points are formed. Alternatively, reflecting points may be formed by inserting concentrated capacity or inductance, or by leaving a gap in the aerial, at a selected point. In the construction shown in Fig. 1, two rectangular aerials D are connected by short leads G and a reversing-switch O to fixed goniometer coils H, the movable coil J being connected, also through a reversing-switch R, to the receiver which may comprise a thermionic valve V. The aerials are tuned by variable inductances I and variable capacities P placed either in series or in shunt across the coils H. The manner in which the aerial oscillates is determined by the insertion of concentrated inductance, or combinations of inductance and capacity, preferably at or near the middle point of the top wire F. The aerial may have a gap either at its outer end, or near 'its middle point, or a condenser may be inserted at the outer end. The aerials may comprise two or more complete loops, or smaller auxiliary loops such as 15, Fig. 9, may be employed at any desired point. The length of each aerial may vary between 1,000 and 9,000 feet, the height between 1¢ and 16 feet, and the lower wire may be from 6 inches to 12 feet above the ground The aerials may be of substantially triangular form with the base 22, Fig. 16, outwards, and the apex 23 towards the receiving station. The upper or the lower wires of the triangular aerials may be horizontal or each may be curved and convex to the other. Specifications 132,548 and 138,586 are referred to.

Filed: 1971-05-10
Abstract: 1276488 Fuel elements COMMISSARIAT A L'ENERGIE ATOMIQUE 10 May 1971 [22 May 1970] 13998/71 Heading G6C In a fuel element in which a column of fuel pellets 24 is supported within a leak-tight can on a bearing member 16 pierced by an axial duct 21 opening into a fission-gas collection space 22, an intermediate component 26 (Fig. 2) is slidably mounted within the can 12 between the pellets 24 and the bearing member 16. Longitudinal grooves 30 are cut in the cylindrical wall of the intermediate component 26 so as to provide communication between radial grooves 29 cut in the flat end faces of the component. As shown in Fig. 1, the bearing member 16 is formed by an intermediate plug joining two tubular sections 12, 14 of the can which is closed by end plugs 18, 20. The intermediate plug is pierced by an axial gas-flow duct 21. The fuel column is thrust towards the plug 16 by a retaining spring 28 placed in an expansion space 31 so as to permit swelling of the fuel during irradiation and maintain the pellets in position during transportation and handling operations. The component 26 may be formed of sintered stainless steel. The advantage of the component 26 is that it provides the fission gases with a number of leak paths which are not likely to be obstructed. If instead of one axial duct in the plug 16, there are a number of uniformly spaced bores around the axis of the plug, it is necessary for the radial grooves 29 of the bottom face of the component 26 to be supplemented by a circular distribution groove having a radius equal to that of the circle on which the bores of the plug 16 are disposed. The fuel element (Fig. 3, not shown) may alternatively comprise a plurality of columns of fuel pellets, e.g. one column of pellets of fertile material and one column of pellets of fissile material, each carried by a bearing member via an intermediate component with a single fission-gas collection space beneath the lowermost bearing member, the pellets of each column other than the uppermost being pierced by an axial duct to allow passage of the fission gases to the collection space.

Patent GB-143358-A (GB)
Abstract: 143,358. Efandem Co., Owen, W., and Cutler, F. E. April 9, 1919. Lighting systems; regulation, automatic systems and apparatus for; systems of charging galvanic batteries.-In a motor-vehicle lighting-set comprising a dynamo D, the voltage of which is controlled by a vibrating regulator, which periodically inserts a resistance R in the shunt field circuit, overcharging of the battery B, when the lamps are disconnected is prevented by inserting this resistance in the field circuit independently of the regulator. This insertion is effected by the lamp switch A, which, in the position shown, disconnects the head, tail, and pilot lamps H, T, P and connects the dynamo to the battery; if the dynamo speed is sufficient, the cut-in switch C closes and charging is effected, the resistance R being in circuit, as the contacts a<5>, a<6> are not bridged. If the switch is then moved clockwise to the next position, the insulated plate g bridges the contacts a<5>, a<6>, and the resistance R is then under the control of the series regulator coil M and its contacts K; the lamps H, T are in circuit. A further movement, used when the vehicle is standing still and lights are required, connects the tail and pilot lamps T, P to the battery, the dynamo being disconnected. A fourth neutral position open-circuits all the devices. The cut-in switch C may be combined with the regulator M, and a switch consisting of a squaresection bar with suitable contacts on its faces may be used instead of the switch A. The armature of the vibrating regulator is in the form of a bar carried by a leaf spring, and the attraction of the electro-magnet is opposed by a compression spring, the resistance of the spring increasing at a greater rate than the increase of attractive force; the coils of the spring close and prevent the armature from reaching the magnet.

Title: Photographic camera
IPC: G03B15/03
Filed: 1976-04-09
Abstract: 1498607 Flash firing mechanism EASTMAN KODAK CO 9 April 1976 [10 April 1975] 14590/76 Heading G2A A camera has a Piezo-electric generator for firing a flash unit, in which the striking means for the generator moves from a standby position to a striking position, and a pair of terminals for conducting the generated energy to the flash unit, these terminals being shorted together when the striking means is in the standby position. Thus the terminals are shorted at all times except when the flash ignition takes place, so minimizing the possibility of premature firing of the flash by electrostatic discharge. Fig. 2 shows the mechanism with the shutter actuator 80 in the tensioned position, and the firing spring 20, which acts as the striking means, also in the tensioned position. One end of spring 20 carries a hammer 26, and a lug 28 which latches with the face 44 of an arm 40 forming part of a latch 30 pivotally mounted on a pin 32. A lug 34 of latch 30 is engaged and biased anti-clockwise by a spring 76 forming part of a contact strip 70, 74 which is joined to the flash terminals 62, 64. The contact strip end 74 is urged by its resiliency into contact with spring 20. A third flash terminal 60 has a resilient portion 68 which is biased into contact with the lower anvil 15 of the Piezo-electric generator 10. Another resilient portion 69 of terminal 60 is biased into contact with another portion of latch 30 in the Fig. 2 position. Thus in this position a shortcircuit is established between terminals 60 and 62 through contact strip 70, spring 20, latch 30 and resilient portion 69. When it is desired to take a flash illuminated picture, the shutter actuator is released to move downwards. This strikes an arm 36 of latch 30, and pivots it clockwise until arm 40 disengages from lug 28 of spring 20. This end of the tensioned spring is now free to move downwards so that the hammer 26 can strike the upper anvil 14 of the Piezo-electric generator 10, so producing the firing pulse. At the same time the clockwise movement of latch 30 causes it to disengage from resilient portion 69, which is held by a stop 71. This disengagement, and also the disengagement of spring 20 from latch 30, opens the circuit between terminals 60 and 62. The electrical pulse from the generator 10 is now presented across these terminals and hence across the flash unit, which is thus fired. After firing, latch 30 is pivoted by spring 76 into the Fig. 4 position, in which a pawl 48 of the latch engages a rack gear 54 on a slide 52. Moving slide 52 to the right advances the film, and re-sets the shutter actuator 80 back to the Fig. 2 position. Return movement of the slide is prevented by pawl 48. The continued movement of actuator 80 back from the Fig. 4 position to the Fig. 2 position returns all the parts of the mechanism back to the stand-by position of Fig. 2.
