Title: Improvements in or relating to photographic cameras employing interchangeable lens mounts
IPC: G03B3/02
Filed: 1957-09-18
Abstract: 822,423. Photographic cameras. KODAK Ltd. Sept. 18, 1957 [Sept. 22, 1956], No. 29401/57. Class 98(1) In a photographic camera having means for attaching an interchangeable lens mount with a' between-lens shutter, released by mechanism on the body, and a movable cover within the camera for shielding the film from light when the lens mount is removed, an actuator for the cover carries a part which blocks the shutter release mechanism when the lens mount is detached, the blocking part being automatically movable to an inoperative position by part of the lens mount when attached to the body. As shown in Figs. 1, 2, the lens mount 2 has a bayonet connection with the camera body 1, and carries a between-lens shutter. The shutter is set through aligned shafts 6, 7 operated by the film wind. A shutter release shaft 8 is slotted at 9 to engage a lip 11 on a shaft 12 (see also Fig. 3) which also carries a member 13 engageable by a shutter release plunger 14. When plunger 14 is depressed, it also actuates a double exposure prevention device of the kind described in Specification 533,878. As shown in Fig. 4, a pivoted flap 19 is spring-urged to close the film gate when the lens mount is detached. When the mount is re-attached, a lug 36 thereon passes through a slot 37 in the camera body (Fig. 1), and, on rotation of the mount to lock it in position, moves a slidably mounted member 26 against action of a spring 34; so that an arm 27 of member 26, acting on a roller 28, raises the cover 19 from the film gate. A lug 38 on member 26 engages a recess 39 in member 13 while the mount is detached to prevent actuation of the shutter release; this lug is disengaged when member 26 is moved as the mount is reattached.

Title: Improved method for manufacturing heating oil
IPC: C10G69/14
Filed: 1952-11-24
Abstract: A mineral heating oil composition, boiling within the range 300-750 DEG  F., having little tendency to deposit carbon when burnt and also useful as a diesel fuel, is prepared by contacting a virgin heating oil with hydrogen in the presence of a hydrogenation catalyst, under temperature and pressure conditions such that the consumption of hydrogen is not more than 60 cubic feet per barrel, and blending the product with a heating oil obtained in a cracking operation.  A process is described in which crude petroleum is fractionated by distillation to yield a virgin heating oil fraction, a gas oil fraction and other fractions.  The virgin heating oil fraction is partially desulphurized by hydrofining with the above-mentioned hydrogen consumption, for example at 400-700 DEG  F. and 50-250 lbs./sq. in. pressure using a cobalt molybdate or molybdenum oxide catalyst supported on a carrier such as alumina.  The hydrofined fraction may be steam stripped or washed with caustic alkali to remove traces of hydrogen sulphide before blending with the cracked heating oil mentioned below.  The gas oil fraction is passed to a cracking zone wherein it is subjected to thermal or catalytic cracking, particularly catalytic cracking in presence of a fluidized catalyst, and the cracking products are fractionated to yield a heating oil fraction and other fractions.  This heating oil fraction may be washed with caustic alkali before blending with the hydrofined virgin heating oil mentioned above.  The blend prepared according to the invention is compared with other blends of sweetened virgin heating oil and cracked heating oil wherein the virgin heating oil is sweetened by (i) doctor treatment, (ii) treatment with lead sulphide and sulphur, (iii) treatment with air and caustic soda, (iv) hypochlorite treatment, or (v) treatment with methyl alcohol and caustic soda.

Title: Process for the manufacture of extracts of egg yolk and for the production of baked goods therefrom
IPC: A21D2/26
Filed: 1937-10-30
Abstract: Extracts of egg yolk more particularly for use in baking are prepared by forming an aqueous suspension of the yolk, adding an ether thereto, agitating and allowing to stand on which the mass settles into an upper yellow layer containing ether-soluble material, an intermediate aqueous-ether protein-containing layer, and a lower aqueous layer, the layer being then separated and the upper and intermediate layers preferably freed from ether as by distillation. The amount of ether used may be equal to the combined volumes of the egg yolk and water which may be present in equal volumes.  The intermediate layer yields on distillation an aqueous suspension of a white protein substance which when added to bread dough increases the volume of the loaf, and may be K  employed when flours deficient in protein are used, and the upper layer gives a yellow-orange coloured oil, which imparts to baked goods the yolk colour and may be separated further into two portions, one primarily a liquid oil and the other a mixture of oil and a solid substance.  The extracts may be added to the dough batch as an aqueous suspension or, when dried in the form of a powder, mixed with the flour.  The various fractions may be combined and used in the dough.  The protein fraction may be used with hydrogenated oils or other shortening compositions or with a phosphatide such as lecithin in making the baked goods.  Examples are given of the preparation of white bread by the sponge and straight dough processes employing the protein fraction and incorporating as a bread improver a mixture of calcium sulphate, sodium chloride, ammonium chloride, potassium bromate and wheat flour, other ingredients of the dough including malt syrup, milk powder, shortening and sugar.ALSO:Hydrogenated oils or other shortening compositions for use in baking are mixed with a protein-containing extract which is obtained by forming an aqueous suspension of egg yolks, adding an ether, agitating, allowing to stand on which the product settles into three layers, the intermediate aqueous-ether protein-containing layer being distilled, giving the protein-containing extract in the form of an aqueous suspension.

Title: Improvements in or relating to bistable circuits
Inventor: BRIDSON IAN
IPC: H03K3/42
Filed: 1964-07-30
Abstract: 1,094,871. Bi-stable circuits. AUTOMATIC TELEPHONE & ELECTRIC CO. Ltd. July 21, 1965 [July 30, 1964], No.30449/64. Heading G1A. A bi-stable circuit employs two similar electroluminescent-photo-conductive devices each consisting of at least one electro-luminescent element and at least two photo-conductive elements. The first device has a photo-conductive element P1a connected between one terminal of an electroluminescent element P1 and one terminal of a fluctuating voltage source V, the other terminal of which source V is connected to a reference potential, e.g. earth. The other terminal of element P1 is connected through a resistor R1 to the reference potential. A second photoconductive element P1b is connected between that terminal of element P1 connected to the resistor R1, and that terminal of the electro-luminiscent element P2 of the other device which is connected to the first photo-conductive element P2a of the other device. If element P2 is radiating, elements P2a and P2b are in the low impedance state, and element P2a permits element P2 to continue radiating by connecting it to source V. Element P2b prepares a path over which element P2 can be shunted from input A. If the source V is now connected to A, element P1 radiates and element P2 is shunted. As radiation from element P1 increases, the impedance of element P1a decreases enabling element P1 to continue to radiate irrespective of the condition of input A. The impedance of element P1b also decreases but, since the radiation from element P2 decreases, there is no tendency for element P1 to be shunted. When the change of state is complete, element P1 is radiating, element P1a, having low impedance, supplies current to element P1, and element P1b, also having low impedance, prepares a shunt for element P1 when a voltage is applied to input B. The change of state from element P1 radiating to element P2 radiating takes place by connecting input B to source V. If the voltage at input A or B is removed when impedances P1a and P2a are equal, both elements P1 and P2 do not radiate for a long time. Further photo-conductive elements (not shown) may control output signals.

Abstract: 1278255 Fuel elements UNITED KING- DOM ATOMIC ENERGY AUTHORITY 19 Sept 1969 [26 June 1968] 30498/68 Heading G6C A nuclear fuel element is made by successively introducing into at least a region of a container particulate fuel components of successively smaller sizes, the first component comprising spheres having a diameter so related to the cross-sectional dimensions of the region to be filled that the spheres are located in layers in this region, each sphere in a given layer contacting the adjacent spheres in the layer and the container wall. The container is continuously vibrated to compact the particles. Where the region is annular in section, the spheres contact both the inner and outer walls of the container. The sphere diameter may be less than the diameter of the inner wall and the second component may have a mean diameter which is greater than <SP>1</SP>/ 6.5  of the sphere diameter. The second component may be irregular and a third irregular component may have a mean diameter which is not greater than 1/10 of the mean diameter of the second component. The components may be UO 2 , for example. Annular spaces provided with cut-away portions at their inner and outer peripheries may be inserted in the container at intervals along the fuel element. The spacers are introduced after specified numbers of spheres have been loaded and the second and third components are then infiltrated via the cut-away portions. The spacers are crimped or otherwise secured to the container. The inner boundary of the annular region may be constituted by the surface of a rod which is withdrawn after the loading of the spheres, the container and the spheres being so dimensioned that the spheres do not fall into the centre of the container. The resulting central hole can, if desired, be filled with spheres or cylindrical pellets of a different material from the outer spheres. The interstices are then filled by infiltration of further components. In this way a fuel element having, for example, a PuO 2  core and a UO 2  annulus can be produced.
