Title: Improvements in or relating to flash light photography
IPC: G03B9/70
Filed: 1939-07-15
Abstract: 531,640. Cameras combined with flash lamps. ABBEY PHOTO CORPORATION. July 15, 1939, No. 20635. Convention date, April 1. [Class 98 (i)] Photographic flash-light apparatus comprises a shutter normally urged into lens-closing position, and opened by electrical means in series-circuit with which is the ignition element of the flash bulb, the ignition element initially passing sufficient current to open the shutter and thereafter, by increase in the resistance or by rupture, diminishing or interrupting the current so that the shutter closes. In the form shown, a pivoted-blade shutter 14 is normally held in the closed position by a spring 19, and is moved to expose the lens by the energization of an electromagnet 13 which is in series with the igniting filament 20 of a flash-lamp mounted on the camera. On closing a switch 10, or a remote control switch 21, the shutter is opened and the flash lamp ignited, the shutter then closing owing to the fusion of the filament which breaks the circuit of the magnet 13. Alternatively, a photo-flood bulb may be employed in which the filament does not fuse, in which case the apparatus is so adjusted that the rise of resistance in the filament due to the rise of temperature, results in the magnet being sufficiently de-energized to release the shutter blade. To prevent the possibility of the shutter re-opening a time switch may be substituted for the switch 10, which remains closed for only a sufficient period to complete the exposure. For daylight exposures a lamp may be substituted for the flash or photo-flood bulb, which either burns out or the resistance of which rises sufficiently for it to cause closure of the shutter as in the case of the photo-flood bulb.

Abstract: 1,192,771. Information transfer. TELEMECANIQUE ELECTRIQUE. 3 May, 1967 [6 May, 1966; 30 Sept., 1966], No. 20659/67. Heading B7N. [Also in Division G4] In a system for transferring information between a vehicle and apparatus disposed adjacent its track, a binary information store is provided on the vehicle and comprises a number of transparent units 1 each formed with an internal passageway 4 which allows movement of a magnetic mass, e.g. ball 7, from a stable position 5 (e.g. binary 1) at one end of the passageway to a similar position 6 at (e.g. binary 0) at its other end. In a second arrangement Fig. 8 (not shown), the ball is replaced by a cylindrical mass and the passageway is shaped as an inverted-V. Information is read into the store by the track apparatus shown in Fig. 4 comprising a magnet 11 attached to a shaft 12 which can be manoeuvred if required by a rack and pinion 13, 14, a spring 17 and electromagnet 16 to raise the ball 7 from one position and move it along the passageway to the second position. The position of the balls may be read at a trackside reading station either by means responsive to the presence of a magnetic mass or since the housing is transparent by photoelectric means. One of the units in the store co-operates with a detector at the reading station to initiate a read out. Magnetic means are also provided for restoring all the balls to the "0" position.

Abstract: 1,216,746. Shearing. DAINIPPON INK & CHEMICALS Inc. 2 May, 1968 [4 May, 1967], No. 20763/68. Heading B3W. Apparatus for shearing metal pipes, bars and other sections comprises a fixed die 5 mounted in a body 3 slidable on a frame 1 and a rotatable die 11 mounted in a fixed housing 4. Within an outer eccentric rotor 7 rotatable in a bearing 6 in the housing 4 is an inner eccentric rotor 8. A die supporter 10 in which the die 11 is centrally mounted is located by a bearing 9 within the rotor 8. The rotors are driven at high speed, 1500-300 r.p.m., by means of a pulley 12. When the eccentric rotors are in the Fig. 2 position the centre P of the die 11 coincides with the centre of curvature of the bearing 6. The die supporter 10 is prevented from rotating on its axis, but allowed to move in a circular path when the relative position of the rotors 7, 8 is varied, by a link 13 which is mounted on a pin 16 on the base means of a slot 15. The position of rotor 8 can be varied relative to rotor 7 by means of an hydraulic piston and cylinder 17 connected to the rotor 7 at 20 and to the rotor 8 at 17<SP>1</SP>. Hydraulic oil is supplied to and exhausted from the cylinder via inlet 23 and outlet 22 and conduits 24, 25 ,28, 29, 32 and 33 in the rotors. In use a pipe, bar &c. is placed in the dies in their Figs. 1 and 2 position, and whilst the rotors are driven the piston-rod 19 is extended causing the die supporter 10 and thus the die 11 to move in a circular path about the centre Q of the inner rotor to shear the pipe &c. A thin walled pipe may be supported on a core (35), (39) (Fig. 5, not shown) during shearing and bars of angle section, such as L and T (Fig. 6, not shown) are made up to a regular solid shape by reinforcing blocks (42), (44), (44<SP>1</SP>).

Filed: 1939-07-18
Abstract: 533,777. Rubber thread. SHEPHERD, T. L. July 18, 1939, No. 20822. [Class 70] Rubber thread which has a high modulus of elasticity and can be easily woven or knitted is prepared by stretching, drying and vulcanizing a rubber thread at a temperature below the annealing temperature, i.e. below 100‹C. The drying is done at about 65‹C., and the vulcanization at room temperature, being effected by the use of ultra acceleration. The treated thread undergoes a small retraction if heated to annealing temperature after vulcanization. The thread may be formed by extrusion or otherwise of latex into a coagulant or by cutting a sheet formed from latex or slightly masticated rubber. In an example, latex containing sulphur, sodium isopropyl xanthate, diethylammonium diethyldithiocarbamate, zinc oxide, antioxidant and stabilizer is spun into aqueous acetic acid. The coagulated thread is stretched 1000 per cent. and dried at 65‹ C. or 830 per cent. and dried at 80‹C. The dried and stretched thread is wound on bobbins and vulcanized by storage at 20‹C. for three weeks. Specifications 423,997 and 520,095, [Group IX] are referred to.

Abstract: 504,915. Two-part couplings; binding-posts; supporting conductors; clamps; fencing. WALLIS, D., and GRUBB, S. E. July 31, 1937, No. 21305. [Classes 36 and 38 (i)] [Also in Groups I and XXV] A gripping device for connecting wires electrically or mechanically comprises a block or plate 1 having a recess therein of wedge shape to receive a corresponding wedge 2 pressed by a spring 3 and guided by a pin-and-slot 6, 7 so as to hold the end of the wire or cable between parallel surfaces 8, 9 that may be grooved to fit the wire or serrated to grip it. A simple terminal as shown in Fig. 3 may be fitted to a fuse base, switch, &c. For multiple connections to a bus-bar, Fig. 5 (not shown), or in a distribution box, Figs. 9 and 10, plates having recesses of wedge shape cut therein house the clamping wedges which are retained by superposed plates. In the distribution box, insulating discs 15 carry metal plates 16 having recesses 17 for the wedges 18 that are pressed forward by springs 19. Several such plates are suparpossd within a housing 20 and serve to connect together several cables or to connect such cables to a plug member 21 the contacts of which enter holes in the plates 16 which are plain or bushed with insulation to produce the desired electrical connections. The cables whose ends are held by the wedges 18 are anchored by a slit resilient plate 22 secured within the housing 20 and engaging the cable sheathing which, if of lead, is thus earthed 'to the housing.

Abstract: 614,595. Television. PARTINGTON, G. E. July 16, 1946, No. 21316. [Class 40 (iii)] [Also in Group XL (c)] Picture signals corresponding to a chart or other pictorial representation of the area scanned by P.P.I. radar apparatus are reproduced, together with the normal target display, on the P.P.I. cathode-ray tube screen. The chart which may comprise a transparency 5 is arranged to be scanned by the luminous spot on the screen of a short persistence cathode-ray tube 1, the deflection circuits 3 being operated from the same scanning circuits as are employed for the P.P.I. tube (not shown) and the picture signals developed by the photo-electric cell 7 are applied to the input circuit of the P.P.I. apparatus after amplification and limiting in 8. The two sets of signals (i.e. picture signals and radar signals) may be strongly differentiated from each other by applying them with different amplitudes to the P.P.I. tube to produce a two-tone picture, or, if the screen in the P.P.I. tube is of the type in which the colour glow depends on the intensity of the electronic bombardment, a two-colour picture. Instead of the abovedescribed arrangement for producing the picture (i.e. chart) signals, the tube 1 may be replaced by a picture signal generating tube such as an iconoscope, in which case the chart need not be in the form of a transparency. Alternatively, mechanical scanning means may be employed to produce the picture signals. The arrangements may be utilized to generate artificial signals for testing a P.P.I. apparatus.
