Title: Automatic apparatus for projecting films
IPC: F16F9/02
Filed: 1959-07-13
Abstract: 899,326. Kinematographic juke - boxes. PRAT, L. F., and BENEDIC, E. July 13, 1959 [July 31, 1958; March 24, 1959], No. 23909/59. Class 40 (2). [Also in Group XX] In apparatus for selectively projecting any one of a plurality of sound-and-picture films contained in individual magazines spaced about common sound-and-picture transducing means and in which the sound is preferably played back from magnetic record tracks on the films, the selected magazine is moved independently of the others into the projection position firstly, by a pivotal movement about an axis lying on an arc generally containing the pivotal axis of all of the magazines and secondly, by a translational shift following the pivotal movement, and means are provided for returning the magazine to its initial position after projection of the film. As shown in Fig. 3 the magazines 9a, 9b, 9c (this latter is shown in the projection position, the inoperative position being 9c<SP>1</SP>), 9d are pivotable, by means of motor 14, worm 15 and pinion 16 (Fig. 2) associated with each magazine, about axes 11 lying generally along the curve 12, in the manner of typewriter letter bars. When the pivoting movement is completed the electrically-operated push-member 13 pushes the magazine against the projecting system 7 whereby the drive-shaft is caused to enter an aperture in the magazine wall and engage the film feed sprocket 19 (see Fig. 4) in the magazine 9 and, via gearing 22, 23 and 24, the claw mechanism 25, 26. Depression of a key (maintained by a spring-loaded locking-bar) energizes motor 14 to pivot the selected magazine into the projection position whereupon motor 14 becomes deenergized and a further motor is started driving a commutator constituted by a number of cams and switches during one revolution of which the following steps occur: the push-member 13 is operated; the main film-driving motor is started; a projection lamp becomes illuminated, its light being introduced into the magazine by a prismatic rod entering an aperture in the magazine wall. The commutator mechanism is at rest at this time to allow projection of the film. Further apertures are provided in the magazine wall for the introduction of a sound head 29 and, at 28, for a lamp co-operating with a photo-cell at the beginning and end of each film (a transparent gate in an opaque strip being provided on the film at each end) to cause the following operations. At the end of the filmrun, light incident on the photo-cell produces an impulse whereby the commutator motor is restarted; the projection lamp is extinguished, and a high-speed re-wind motor started, the commutator thereupon remaining idle until, at the end of the rewind, a further photo-electric pulse re-starts it thereby causing motor 14 to be driven in a reverse direction to return the selected magazine to its inoperative position. At the same time, an electromagnet is energized to release the selector keys.

Title: Improvements in control devices for electric illuminating signs
IPC: G09G3/00
Filed: 1924-10-09
Abstract: 244,854. Ostermayer, W. Oct. 9, 1924. Stencil switches.-Comprises control mechanism for flashing signs of the kind in which electric lamps arranged in a uniform field are selectively illuminated under the control of an electric switch of the stencil type. The stencils consist of rigid plates 4, Figs. 1 and 2, made of metal or of strong insulating material and carrieu by an endless chain 5 which travels over rollers 18, Fig. 1, and is provided at intervals with inwardly projecting pins 8, Fig. 2, which engage under sleeves 7 attached to the stencils and so lift these in succession off the lower end of the rails 6 on which they are stored. The stencils 4 are then drawn through the switching device to the top of Fig. 1, and on their downward movement are caught by the upper end of the rails 6, down which they then slide. Several pairs of rails 6 may be employed, the chain being deflected by manually or automatically operated guides so as to select the pair of rails which is to be brought into operation. The upper part of the chain is inclined to the vertical as shown so that the stencils 4 only need to be tilted through an acute angle during their passage. In a modification, instead of being detachable for storage on rails 6, the stencil plates may be linked together at their edges and folded concertina-wise for storage in containers, from which they are lifted by a chain similar to 5. In the form shown in Fig. 3, the stencils 4 are pivoted on their carriers and engage a rack 21 while passing through the contact device, so that they are caused to revolve in order to give a revolving design on the lamp panel. The stationary contacts 2 are connected to their respective lamps and comprise pivoted arms carrying rollers at their lower extremities, these rollers being adapted to pass through the gaps in the stencils. When the stencils are made of metal they are connected to the return conductor during their passage through the switching device but they are insulated from the chain by the sleeves 7 so that they may be electrically dead when not in action. In this case the plate 1 beneath the stencils is of insulating material. Alternatively the stencils may be of insulating material and the plate 1 may be connected to the return conductor. In a modification the arms 2 may by their rocking action open and close electric switches controlling the lamps, so that no current passes through the parts shown in Fig. 1.

Title: Growing crystals on a substrate
IPC: C30B19/08
Filed: 1971-04-19
Abstract: 1315298 Crystallizing from a melt WESTERN ELECTRIC CO Inc 19 April 1971 [16 March 1970] 24033/71 Headings B1G and B1S In order to improve crystal growth, e.g. of an epitaxial layer of Ga P from a solution in a mixture of Ga, Ga 2 O 3  and Zn, on the surface 73 of a substrate 64, the substrate is shielded from impurities, by a cover plate 72, which is held down over it, while the melt is being heated and only raised at the crystal growing temperature. During crystal growth a heat sink 79, through which cooling gas may be passed, maintains a vertical temperature gradient in crucible 61, having horizontal isotherms, so that a uniform crystal layer is produced. When the desired thickness has been reached growth may be stopped by returning the plate 72 on tilting the furnace 74, thereby tipping the melt off the substrate. Confining the substrate in a closely fitting recess (62) out of contact with the melt, is stated to limit thermal degradation (by volatilization of an element) to one monolayer of the surface 73. This effect may be enhanced by making plate 72 of the same material as the substrate, whereby it also serves to maintain saturation of the melt. Alternatively, it may be made of an inert material, which may be the same as that from which the crucible 61 is made, e.g. pure graphite, alumina, quartz, boronitride or an inert ceramic material.

Abstract: 1,107,054. Continuous casting machines. COMPAGNIE FRANCAISE THOMPSONHOUSTON HOTCHKISS BRANDT. 8 June, 1965 [9 June, 1964], No. 24294/65. Heading B3F. A continuous casting machine comprises an annular mould member 2 carried on an annular support member 28, the mould and support member being supported in a horizontal or inclined plane on frusto-conical rollers 52, and the mould being rotatably driven by a drive roller 60 located inside and in frictional contact with the support member, co-operating with a spring loaded support roller 66 engaging the outside surface of the support member. The mould 2 is formed with a head portion which contains a casting groove 4 and an integral downwardly depending flange portion 26, which is supported on shims 30 on the support member 28. Side members 38, and 40 are attached to the member 28 so as to form an annular channel on the support 28 into which the flange 26 of the mould 2 extends. Cooling liquid is circulated in the channel and means are provided for controlling the level of the coolant and so control the solidification of the casting in the groove 4. Positions around the casting groove annulars are predetermined for the supply of molten metal to and the removal of the continuous casting from the groove 4 respectively. The mould groove may be lubricated by spray means 22 with colloidal graphite to facilitate the easy removal of the casting. Prior to casting, the inner surfaces of the groove 4 are coated with a layer of heatinsulating and refractory substance such as any of various silicates, Aluminates or Bentonite which prevents over heating of the mould and over cooling of the casting. It may be desirable for the casting to solidify in controlled atmospheric conditions, in which case, an annular hood 48 of inverted channel section may be suspended from a supporting structure 49 the sides of the channel projecting into the coolant trough thereby forming an annular gas-tight tunnel enclosing the mould member 2. A stationary wedge member 16 located in the casting groove 4 facilitates the removal of the solidified casting which is carried immediately to a hot rolling stand 20. The tundish 12 from which the molten metal is poured into the casting groove 4 may be movably mounted, Fig. 8 (not shown), and adapted by means of a roller follower 90 to always remain in the same position relative to the groove 4 irrespective of the changes in dimension of the annular mould due to expansion and contraction, Fig. 5 (not shown).

Patent GB-599757-A (GB)
Title: Improvements in or relating to the production of fat-soluble vitamin concentrates
IPC: A61K31/59
Filed: 1945-09-24
Abstract: Vitamin concentrates are obtained by the partial saponification with alkali of a vitamin-containing marine oil, separating the soap formed from the unsaponified residue by the use of a non-polar solvent and treating the latter with a polar solvent, e.g. methanol or ethanol to remove that portion of the said residue soluble therein, the reaction mixture of alkali and oil being cooled sufficiently during the saponification, e.g. below 35 DEG  C.  Concentrates of greater potency may be obtained by retarding the saponification further by means other than temperature control, e.g. by adding 1/2 to 1 per cent of a polar catalyst such as isopropanol.  The examples describe the concentration of soupfin shark liver oil, ling cod oil and halibut liver oil by the process above.  Specification 585,573 is referred to.

Abstract: 430,867. Colour photography. OPTICOLOR AKT.-GES., Glarus, Switzerland. Aug. 28, 1934, No. 24772. Convention date, Sept. 4, 1933. [Class 98 (ii)] To avoid unsymmetrical diffusions in projecting colour-record lenticular films, a filter is used in which the zones are substantially symmetrical about their centre lines parallel to the lenticular elements, these lines being so spaced that their images projected by any lenticular element onto the picture layer are equidistant from one another and from the images formed by an adjacent element, the distances apart being equal to the width of a lenticular element divided by the number of filter zones. The filter is also such that on projecting a blank lenticular film the sums of the fundamental sensations of the human eye excited by the zones are the same for each zone. Original films in which these conditions are not fulfilled may be reproduced so that this condition is fulfilled in the copy. Suitable forms of filter are shown in Figs. 3 and 6. The zones 4, 5, 6 may be bounded by curved lines as in Fig. 3 or by straight lines as in Fig. 6, in which additional zones 41 and 61 corresponding in colour to the zones 4 and 6 are used. A mask having an opening 10 is arranged separately from the filter so that the part within the rectangle 10 is visible from the central image on the film under a lenticular element whereas the part visible from a lateral image is bounded by the rectangle 10<1>. Opaque strips 11 are arranged between the zones.
