Title: Illuminating apparatus
IPC: G03B15/02
Filed: 1965-06-24
Abstract: 1,047,603. Illuminating apparatus. S. H. HINE. June 24, 1965, No. 26809/65. Heading G2A. [Also in Division F4] An illuminating apparatus comprises a first light source, supported from a wall 10, which is a planar arrangement of annular fluorescent tubes 18, either in the form of separate concentric circles or a continuous spiral. The turns are closest together at the centre, where they surround an opening 12. Through this opening projects the lens system 36 of a camera 34. Also comprised is a second light source 44, projecting a beam of light 54A which is generally divergent after passing through a cross-over point 54. The divergent beam is partially reflected by a semi-relective mirror or beam-splitter 30, set at 45 degrees to the axis of the beam. The mirror 30 is set in a hermetically sealed, preferably evacuated, housing 24 secured to a flanged part 14 of wall 10 surrounding opening 12. The housing has a window 26 and two further windows 28. The optical geometry is such that the reflected beam 54A appears to originate at a virtual source 58 at the centre of the camera diaphragm 38. The beam falls on a retro-reflective screen 60, so that all the light is reflected back to the virtual source 58. At the same time, the screen is also illuminated by light from source 18. Thus any object, such as a ball 66, in front of the screen, is illuminated in such a way that its outline shows up on a photograph sharply and clearly, and free from penumbral shadows which would be produced by random reflections from the surface of the ball itself (Fig. 4a, not shown). If source 18 were extinguished, and source 44 used alone, the ball would show up on a photograph as a black circle having a sharp clear outline against a white background. A drawing which is to be reproduced may be made directly on the retro-reflective screen, or on a transparent overlay placed against it. The illuminating system of the invention is not considered as limited to the photographic application described.

Title: Improvements in and relating to the manufacture of paints
IPC: C09C3/00
Filed: 1921-10-11
Abstract: 195,996. Gardner, D. Oct. 11, 1921. Pigments; incorporating paint ingredients.- In a process of paint manufacture, pigments comprising compounds of metals of the fourth, fifth, and sixth groups of the periodic system are used. The pigments consist of a base and a filler, both being compounds of metals of the same group, that have been calcined at a temperature not exceeding 600‹ C. All ingredients must be free from moisture, and the pigment is preferably mixed, while still hot, with the vehicles, driers, &c. Impurities are removed from the oxide or salt chosen as base, and moisture is removed by calcining. The base is then mixed with the calcined filler, or the mixing may precede the calcining. The pigment is crushed and sieved, and is mixed with the other ingredients such as oils, chlorinated or aromatic hydrocarbons, turpentine, turpineol, dipentene and in a mill. In making pigments, equal parts of bases such as titanium oxide or zirconium hydroxide or silicate- and fillers such as keiselguhr, silica, and silicates. may be used. Equimolecular amounts of antimony oxide is preferable as a filler for bases of the fifth group, and molybdenum oxide for bases of the sixth group. For heat-resisting and waterproof paints, moisture is eliminated by stirring equal parts of pigment and an oil such as linseed, maize, castor or menhaden oil, in an autoclave under 5-8 atmospheres pressure. In an example, a pigment comprising zirconium oxide as base, and titanium oxide as filler is treated with boiled linseed oil. Pigments comprising oxides of cerium, thorium, vanadium, niobium, tantalum, tungsten, uranium and molybdenum may also be treated in this manner. The Provisional Specification also describes a pigment comprising a mixture of zirconia and thorium oxide (from sulphate) with silica or a silicate, and states that chromium oxide may be used as a base with molybdenum as a filler.

Abstract: 206,504. Etablissements E. Belin. Nov. 4, 1922, [Convention date]. Type-composing. - In an optical receiver for type-printing telegraphy in which as described in Specification 9556/11 the image of each character illuminated on a screen in accordance with the received signals is reflected by a mirror system on to a photographic strip, a system of rotating mirrors is provided, each mirror reflecting to a point on the strip in advance of the point to which the preceding mirror reflected. Figs. 1 and 2 show two optical arrangements for illuminating the signs. A lens L<1>, Fig. 1, produces at S<11> an image of a source of light S, the convergent beam traversing a rectangular aperture in a diaphragm D and a lens L<2> before reflection by the mirror M of the receiving galvanometer. The reflected beam traverses a cylindrical lens L<3> producing a condensed image of the aperture at D" in the plane of a screen to illuminate a sign on the screen corresponding to that transmitted Alternatively, a lens L<1>, Fig. 2, produces at S<1> an image of the source S, a lens L<2> placed at its focal distance from S<1> produces a parallel beam which falls on the mirror M, and the reflected beam is received on the appropriate sign on the screen G. Figs. 4 and 5 show the arrangement for bringing the images into lines on a sensitized strip. Mirrors m<1> to m<50> in number corresponding to the number of signs per line of print, in this case fifty, are spaced in spiral relation along a shaft x arranged at 45‹ to the screen G and rotated in synchronism with the illumination of the signs. A lens l in front of the screen brings the rays to a focus at y, and the resultant images are produced at r<1> to r<50> in line on the sensitized strip. An alternative arrangement, for. use when the signs on the screen G have a wide range, is shown in Fig. 6. Lenses l l<1> in front of the screen produce an image of the screen at G<1>, and the beam is intercepted by a mirror Á made up of elements Á<1>, Á<2>, &c. of a number equal to that of the signs on the screen, arranged to bring the images of all the signs to a focus at gamma, and the spiral arrangement of mirrors is interposed between the mirrors Á<1>, Á<2>, &c. and the point y.

Title: Improvements in and relating to the manufacture of pellets or granular material

Abstract: 803,823. Pelletizing clay &c. STRUCTURAL CONCRETE COMPONENTS, Ltd., and SAINTY, C. L. Sept. 14, 1956 [Sept. 27, 1955], No. 27457/55. Class 87(2). Pellets, &c. of clay or like plastic material are manufactured by extruding continuously strips of the plastic material onto the upper edges of spaced blades 48 travelling in substantially the same direction as the strips and disposed transversely to said direction, pressing the strips with roller 49 to cause the blades to enter and at least partially divide each strip to produce uniform sections, at least partially drying said sections, and discharging them as separated pellets. The strips are fed onto an endless webbed conveyor belt 41, which carries a plurality of the upstanding uniformly spaced blades 48, and beneath the transversely disposed roller 49 rotatably mounted above the blades. The sections on the belt then pass (by means of airlocks) through a preliminary drying chamber 66, a drying chamber 71, and a cooling chamber 77, so that the outer layers of the sections are dried and the sections are discharged from the diverging blades as they pass the driving roller 45 with the aid of extractor roller 83 (not shown) and an air blast. In the first instance the moist clay is fed to an accumulator vessel 5 by a pump 2, said vessel having a resiliently loaded piston 6 to vary the rates of discharge to a screw pump 18a. The clay is fed from the vessel 5 to a pressureregulating cylinder 17 feeding the pump 18a, via a regulating valve 18 which has a by-pass passage 26 (not shown). The valve 18 is automatically regulated by the height of the clay in cylinder 17 below a resiliently loaded piston 20. The pump 18a feeds the clay to extrusion nozzles 39, and thence the strips are fed via guides 40 to said blades 48. These blades move faster than the extruded strips and the resulting loops are periodically cut by wire 100. On discharge from the blades, the partially dried sections are fed into a heated rotary cylinder 88 internally threaded at .the entry end, wherein said sections form spherical pellets. Roller 49 and blading 48 are continuously lubricated.
