Title: Improvements in or relating to stereoscopic photographic cameras
IPC: G03B35/10
Filed: 1929-09-02
Abstract: 338,250. Rudall, C. A. Sept. 2, 1929. Stereoscopic kinemato graphy; stereoscopic systems. -In a camera of the kind in which the lenses are set so that the light rays passing therethrough fall upon reflectors, arranged one at each side of the camera, which cause the rays to converge towards the axis of the camera, the lenses are movable about vertical axes so that their optical axes may be caused to converge on a point at any desired distance in front of the camera. The two lenses may be moved simultaneously, and the reflectors may be fixed or be movable with the lenses. To avoid distortion of the images in the focal plane, (1) the two exposures may be made in succession, the plate or film being turned so that for each exposure it faces the corresponding reflector; or (2) in the case of a film, this may be guided so as to assume a parabolic cross-section, or may be passed through two exposure gates in succession each arranged at right angles to the corresponding reflected rays. In the case of kinematograph films, the images may be formed either in superimposition in one picture area, or in alternating sequence. In a modified camera, a single displaceable lens may replace the stereoscopic pair, and may be used in conjunction with a single displaccable reflector. As shown in Fig. 1, the lenses a, b and reflecting prisms e, f are rigidly connected by frames c, d adapted to turn on vertical pivots g, h. The sensitive plate or film j may be rotated into either of the dotted positions for the two exposures; or, if a film, may be curved as shown at j<3> by chain-dotted lines. In the modification shown in Fig. 2 for kinematography, the film o is passed over a guide m so that the left and right pictures may be taken with the film disposed at right angles to the rays forming them. A single lens and prism construction is shown in Fig. 4 in which the combination is mounted on a frame w rotatable about an horizontal axis x. Movement of the frame to displace the lens and prism combination into the chain-dot position may automatically produce rotation of the plate to the corresponding position normal to the reflected rays, and also actuate the shutter mechanism to effect the two exposures.

Title: Nitro and nitrito derivatives of organosilicon compounds
IPC: C08G77/00
Filed: 1960-08-02
Abstract: The invention comprises nitro and nitrito alkoxy silanes of the formula: <FORM:0948490/C3/1> where Z is the nitro or nitrito group, a is 3 to 18, R is a monovalent hydrocarbon group, R1 is alkoxy, n is 1 to 3, b is 0, 1 or 2, and n+b is not greater than 3, and also comprises the siloxanes containing the units <FORM:0948490/C3/2> The compounds are prepared as mixtures of nitro and nitrito derivatives by reacting a metal nitrite with the appropriate haloalkyl silane or siloxane in an inert organic liquid below 50 DEG C. Suitable metal nitrites are those of Group 1A or 1B, e.g. silver and sodium nitrites. The siloxanes may be cyclic, having 3 to 7 units, or linear, and may be copolymers containg other conventional siloxane units. They may also be prepared by hydrolysing the corresponding silanes.  In the examples: (1) silver nitrite is reacted with gamma-iodopropyltriethoxysilane in diethylether giving gamma-nitro and -nitrito-propyl-triethoxy silanes; (2) gamma-nitropropyltriethoxy silane is hydrolysed with 0.1N HCl to give the polysiloxane; (3) the nitrito compound is similarly hydrolysed; (5) 3-iodo-propyldimethyl-ethoxysilane is reacted with AgNO2 to give a mixture of 3-nitro-and 3-nitritopropyl dimethyl-ethoxy silane. Other examples describe the preparation of (4-NO2-Bu)-PhSi(OBu)2, (11-NO2-C11H22)-MeSi(OEf)2, (3-NO2-Pr) penta methylcyclotrisiloxane and 4-nitrobutylnonamethylcyclopentasiloxane, and the corresponding nitrito derivatives.

Abstract: 1,184,305. Reactor fuelling arrangements. COMMISSARIAT A L'ENERGIE ATOMIQUE. 6 June, 1968 [7 June, 19671, No. 26963/68. Heading G6C. In a storage coffin for a spent nuclear assembly the assembly is immersed in liquid sodium which is circulated by an electromagnetic pump. In the latter, a thermocouple generates an electric current in the sodium which reacts with a magnetic field to provide the pumping action. In the pump, the struts 2, 3 connect the radiator 4 with the sodium duct 1. The struts are of iron and constantin respectively and generate a current in the sodium due to the temperature difference between 1 and 4. The permanent magnets 5, 6 cause the liquid sodium to be circulated along the duct. The pump is mounted beneath the cell 16 to which it is coupled by the ducts 1 and the sodium circulates in the annular chamber 17 downwards through the fuel assembly 15. The heat released from 15 is transferred by the liquid metal to the walls of 16, from which it is dissipated by heat exchange with the surrounding atmosphere.

Title: Improvements in printing and producing kinematograph and other picture films
IPC: G03B27/08
Filed: 1927-10-12
Abstract: 286,568. Thornton, J. E. Oct. 12, 1927. Enlarging, copying, and reducing.-A method of printing from a single-width negative film or printing clichÚ bearing two component imageseries (for example, colour records) in alternating picture-sequence upon two parallel single-width strips, or a double-width strip of sensitive film material, so as to reproduce simultaneously the two image-series side by side in consecutive picture-sequence, consists in employing a printing aperture for each positive strip, the apertures being arranged one in advance of the other, and the distance between them being sufficient to permit the negative film to be curled into a loop without distortion in its passage from the first aperture to the second. The apertures c', c<2> Fig. 4, are formed in a mask under which the positive film strips B', B<2> are moved intermittently one picture space at a time along trackguides, a slack loop of film being formed between the apertures. The negative film A, which is similarly guided and fed two spaces at a time, is curled at a in its passage between the, apertures c<1>, c<2>, and it may also be twisted so as to reverse the images printed at the second aperture c<2>. A lens is disposed at each aperture between the negative and positive films. Separate registering pins are provided at each exposure aperture, the one-hole registration method of Specification 233,991, [Class 98 (ii), Photographic processes &c.]. being preferably adopted, and the registration holes are used as guides when the two positive films are subsequently cemented together to produce, for example, a natural colour picture series, and a set of feed perforations is formed in the finished film.

Title: Information storage apparatus
IPC: G06F17/30
Filed: 1974-06-19
Abstract: 1491706 Data processing; information retrieval INTERNATIONAL COMPUTERS Ltd 9 April 1975 [19June 1974] 27093/74 Heading G4A An input word I, e.g. the index of a record stored in a disc file 10, is transformed, 20, into a plurality of addresses J1, J2 for respective bit map storage areas 18 and a predetermined pattern of bits is written into the addressed locations, one bit at each address J1, J2. Application of a subsequent input word I to the system may be used to read the maps at the transformed address set J, read-out of the predetermined bit pattern indicating that the word I had been applied during the write-in phase, though such indication may be spurious. In an information retrieval system, a search key is compared, 14, with a field F1 of successive records 12, e.g. for equality or inequality relationships, each hit detected resulting in an all 1's pattern being written into the address set derived from the corresponding index I, and the total number of hits being counted, 32. A second scan of file 10 is then made to count, 42, 44 the number of recorded hits in maps 18, some of which may be spurious. If the two counts are equal, the counters are reset and the end of the search is signalled. If the counts 32, 44 are not equal the address transformation operation is modified and the process repeats until counts 32, 44 are equal after the two scans of file 10. The end of search signal enables a retrieve or combine operation to be initiated, the former gating out, S4, a selected field F2 of each record registered as a hit in maps 18 and the latter gating out, S8, a field F2 of each record registered as a hit in maps 18 which also satisfies an additional search criterion supplied to comparator 14. The address transformation unit may be formed by shift registers, the bits of the index I being shifted into different shift registers to form addresses J in dependence on the bits stored in selector registers. The unit may be modified by relative shifting of the selector registers. Modifications.-Spurious hits may be eliminated by registering them in further bit maps. Several searches may be performed simultaneously each using a different transformation unit and set of bit maps. The bit maps may be different areas of the same memory and may be sequentially accessed. A different transformer of I may be used when reading the bit maps from that used when writing.

Abstract: 359,143. Time switches. HENRY, W., 24, Sagimor Gardens, Bloomfield, Belfast. Sept. 11, 1930, No. 27191. [Class 38 (v).] A time switch for automatically switching on the tail lamp of a motor car half an hour before the head-lights are switched on comprises a drum 6 which is pressed by a spring 10 against the bent-round end 8 of the spindle 7 on which it is mounted, and is driven by the hour wheel of a clockwork mechanism (not shown). Once in twenty-four hours a step 21 coincides with the abutment 8 and the drum 6 moves to the right, moving with it a sleeve 24 slidable on a spindle 25 and carrying a pawl 26. A ratchet wheel 27 is thus moved on one step and in turn rotates a second ratchet wheel 31 to trip a pawl 33 thus allowing switch contacts 42, 43 to close under the action of a spring 35. A knob 41 is provided for switching off and at the same time resetting the switch. The abutment 8 slides up the slope 22 and resets the release drum 6. Two such mechanisms are provided, that is for side lights and tail lights, both geared to the hour wheel of the same clock and are set so that one releases at a fixed time before the other for all settings of the bevel gear mechanism 13, 14, 15 and pointer 19.

So that the suspension point 12, Fig. 2, of a container lifting frame can be adjusted to lie vertically above the centre of gravity of the container, it is slidably mounted on an arm 6 which is rotatable within a circular track 5, the latter being attached by struts 4 to a rectangular portion of the lifting frame. The arm 6 and subsidiary arms 8 carry guide rollers 7, 9 at their respective ends. One of the rollers 7 is driven by a motor 14 mounted on the arm 6 by a bracket 13. A motor 17 drives the suspension point 12 along the arm 6 by either a screw and nut or a rack and pinion. In a second embodiment, Fig. 4 (not shown), an arm 6 is moved along parallel rails supported above the lifting frame instead of being rotated. In both embodiments the movements may be produced manually, either through cranking handles or directly. Fig. 5 shows the suspension point 12 attached to a link 19 with a suspension eye 20. Four struts 21 are provided with transducers 22 which control the motors 14, 17 to adjust the lifting frame to any predetermined attitude.

Abstract: 1429936 Fuel injection pumps SIMMS GROUP RESEARCH & DEVELOPMENT Ltd 29. May 1973 [10 June 1972] 27231/72 Heading F1A A fuel injection pump comprises a plurality of fixed stroke plungers 15 reciprocable in respective bores 16 each having a spill port 23, and a plurality of rotory spill valves 21 each controlling the flow of fuel through a respective spill port 23, the valves 21 being axially and angularly adjustable to vary the quantity and timing of the fuel injected. The bores 16 are arranged in an in-line V configuration. The plungers 15 are reciprocable by cams 14 on a cam-shaft 13, the latter driving via gearing or belting a pulley 30 for driving the valves 21 and a centifugal adjusting device. The device comprises two pairs of weights 33 pivoted to a flange 31 fixed to the pulley 30. One pair of weights 33 has arms (40) which co-operate with a plate 39 to move axially a rod 38 against the action of an operator adjustable leaf-spring 41, the rod 38 being non-rotatably slidable in a member 34 helically splined to the pulley 30. The other pair of weights 33 has legs (37) which import axial movement to the member 34 against the action of a spring 35, the axial movement being converted by the helical spline into angular adjustment with respect to the pulley 30; This effects a change in timing. Each rotory valve 21 has an arcuate land 49 having a straight leading edge (47) and a sloping trailing edge (48) whereby axial movement changes the effective width of the land and hence the period of closure of the spill port 23. This effects a change in the quantity. A feedpump 43 delivers to a gallery 25 to which fuel spills and from which it enters the bores 16 during the suction strokes. Fuel in the gallery 25 assists springs 17 in maintaining the rollers 19 of the plunger tappets 18 in contact with the cams 14.
