Title: Camera assembly with adapter for percussive flash bulbs
IPC: G03B15/03
Filed: 1971-04-26
Abstract: 1335912 Photographic cameras PRONTOR-WERK ALFRED GAUTHIER GmbH 26 May 1971 [10 July 1970] 17201/71 Heading G2A A camera 1, having a shoe 7 for receiving percussive type flash bulbs such as flash cubes, is provided with a detachable adaptor 8 which can receive a percussive flash bulb e. g. a cube 9, there being a flexible cable 12 for transmitting force from a point 11 of the camera to the adaptor 8 or to the flash cube 9 so as to release a tensioned torsion spring associated with a bulb 10 to be fired. The camera may also have a conventional contact arrangement for electrically ignitable flash bulbs. In one embodiment, Fig. 4, a disc 16, mounted on a shaft 15 which opens and closes the shutter blades, forms part of a spring drive for supplying force to the point 11. On depression of the camera release button 5, the shaft 15 rotates anti-clockwise (as seen) thus displacing a locking lever 22 and allowing the disc 16 to rotate due to spring 18. Pin 17 on the disc 16 raises a slide 26 which thus transmits force to the point 11 via a cable 25. The disc 16 and slide 26 are returned to the positions shown during cocking of the shutter drive mechanism. In another embodiment, Fig. 10, a rigid plunger 33 is provided for transmitting movement of the slide 26 to a pin 39 to displace a cocked torsion spring. Normally the plunger 33 is retracted wholly inside the camera, Fig. 8 (not shown), but insertion of the adaptor 8 pivots the plunger 33 into the position shown. A locking device 41-45 is provided to prevent operation of the shutter if the bulb 10 in the firing position has already been used. In a further embodiment, Figs. 13-15 (not shown) the force transmitting point (11) is provided directly on the shutter casing (48), and a lifting pawl (56) is mounted on shutter driving disc (50), which pawl acts on the cable (12) to supply force thereto. In another embodiment of the adaptor, Fig. 16, spring drive 61-66 tensioned by rotation of the flash cube 9 is provided for releasing the torsion springs thereof. The spring drive is released by movement of a plunger 126 of the cable 12 in response to force supplied to the point 11 or (11'). A further embodiment of the adaptor, Fig. 19 (not shown), contains means for testing whether the torsion spring (88) of the bulb to be fired is in the tensioned position or not, and for providing a visual indication of the spring state on the side of the adaptor.

Title: Improvements in and relating to the production of slow acting calcium phosphate fertilizers
IPC: C05B1/02
Filed: 1944-09-08
Abstract: A slow-acting fertilizer is obtained by heating a mixture of phosphatic materials, such as ground rock phosphate or bones, with sulphuric acid, say of 77-78 per cent. concentration, at 250-600 DEG C. employing 0.6 to 1.6 mols. acid per mole P2O5, with additional acid to react with impurities. Before the heating step, the mixed rock and acid may be preliminarily heated to a temperature below 250 DEG C.  The material to be heated may also be prepared by adding to phosphate rock, rock which has already been reacted with the requisite amount of sulphuric acid to give the correct P2O5 acid ratio in the final mixture.  The calcining may take place in a rotary cylinder in an atmosphere of air, waste gases, or steam.  The product may be granulated by mixing it with ammonium or sodium nitrate in the presence of water.  According to the Provisional Specification, the best treatment may take place at any temperature above 200 DEG C. and the mixture of phosphatic material and acid may stand for 12 hours before being heated.ALSO:A mixer fertilizer is obtained in granules by mixing sodium or ammonium nitrate with a slow-acting phosphatic fertilizer in the presence of water, such phosphatic fertilizer being prepared by subjecting a mixture of phosphatic material (e.g. rock phosphate) and sulphuric acid in the proportions of between 0.6 and 1.8 mols. acid per mol. P2O5 to a temperature between 250 DEG  and 600 DEG  C. (see Group III)

Title: Automatic frequency control circuit
IPC: H03J7/04
Filed: 1963-05-03
Abstract: 1,029,853. Automatic frequency control- STANDARD TELEPHONES & CABLES Ltd. May 3, 1963, No. 17540/63. Heading H3A. In a superhetrodyne receiver the input or anode impedance of the mixer valve is varied by an A.F.C. voltage to control the local oscillator frequency to produce a constant mean I.F. The output of local oscillator 12 is applied via capacitor 60 to the anode of mixer valve 25 and thence via the anode-grid capacity of the valve to the signal grid where it mixes with an input signal applied via R.F. amplifier 10. The anode-earth impedance of the mixer valve is varied by an A.F.C. voltage, derived from discriminator 15, and applied to the mixer grid. This variable impedance in parallel with the local oscillator tuned circuit varies in turn the oscillator output amplitude, the automatic bias supplied to the oscillator grid, the input capacitance of the oscillator valve and hence the oscillator frequency. In a second arrangement, Fig. 2 (not shown), the output of the local oscillator circuit is connected to the mixer grid and the variation in input capacitance of the mixer valve with variation in A.F.C. voltage provides the frequency control. Furthermore, since the anode current of the mixer is also varied by the A.F.C. voltage, these variations can be applied to the anode circuit of the oscillator by the use of a common resistor producing variations in oscillator output amplitude and a frequency control of the type initially described.

Filed: 1919-07-17
Abstract: 143,095. Balch, E. G. July 17, 1919. Lamp signals.-A device for giving coloured light signals, particularly suitable for use on aircraft, comprises a lamp in a casing provided with a number of windows so that light is simultaneously emitted in a corresponding number of directions, a colour-changing screen being situated between the lamp and each window. The apparatus is arranged to show the same colour through all the windows, and to change the colour, simultaneously. An electro-magnetic step-bystep device is described for controlling the colourchanging mechanism from a distance. As described, the casing 10 containing a lamp 16 has four windows 14 spaced round the sides, and a fifth window 15 on top. Between the lamp and the windows are corresponding rotatable disks 23, 28 provided with apertures carrying transparent material of the required colours. Condenser lenses 30 may be mounted between the lamp and disks. The disks are simultaneously rotated through gearing from a crown-wheel 19, on the spindle of which is a wheel 51 gearing with a wheel 50 secured to a rotatable arm 48, the outer end 47 of which acts as an armature attracted by one or other of a number of electro-magnets 43, corresponding with the coloured apertures in the disks. The electro-magnets are energized singly, the circuits being controlled by a handle 34 moving a contact-arm so as to bridge one or other of a number of pairs of fixed contacts 40, each pair being in circuit with a corresponding electro-magnet. The fixed contacts are within a casing having segments of transparent material corresponding in colour with the colour signals and bearing, if desired, suitable word indications. The desired signal is given by setting the pointer end of the handle 34 to the corresponding segment. The segments may be continuously illuminated by a lamp within the casing, and the lamp 16 may be illuminated continuously. Alternatively, arrangement may be made so that the lamps are lit only when a pair of contacts 40 is bridged. In this case, tell-tale lamps may be provided in the controller casing, so that only the segment corresponding with the order given is illuminated, and as the circuit of lamp 16 is broken when the handle 34 is midway between adjacent pairs of contacts 40, the signal lamp gives flashes as the colour is being changed, calling attention to the change.

Title: A process for preparing liquid saturated hydrocarbons
IPC: C07C2/62
Filed: 1937-07-01
Abstract: Saturated liquid hydrocarbons are obtained by condensing one or more of the alkenes containing 3 or 4 carbon atoms with isobutane in the presence of 90--100 per cent sulphuric acid at about -10 to 30 DEG C.  Intensive mixing, e.g. rapid stirring, is essential. Inert gases may be present; for example cracking gases containing isobutane and the alkenes may be employed.  The isobutane and alkene are preferably present in equimolecular proportions and may be in the gaseous or liquid state.  The process may be effected continuously at normal, reduced or raised pressure.  In examples: (1) an equimolecular mixture of isobutane and propene is introduced with stirring into 96 per cent acid at 20 DEG  C.; (2) and (3) normal or isobutenes are used in place of propene, the temperature being 0 DEG  C.
