Abstract: 1,154,802. Photographic cameras. PRONTOR-WERK ALFRED GAUTHIER G.m.b.H. June 2, 1967 [June 18, 1966], No.25577/67. Heading G2A. A photographic camera has a diaphragm setting mechanism of the follow-up type wherein an exposure meter needle 4 is engaged by sensing member 6 upon depression of release button 2, and an electronic shutter timing circuit controlled by a photo-resistor 20, Fig. 5 subject to ambient illumination. The photo-resistor 20 is in circuit with meter 5 when switch S 3  is in the position shown. Needle 4 is clamped by a yoke 8 in a position dependent upon the ambient illumination. Sensing member 6 actuates a diaphragm blade setting ring 13. The shutter has blades 24 within a ring 25 engaged by a pawl 27. A stop lever 28 co-operating with a release lever 29 actuated by button 2 engages a spring operated disc 26. In operation, film sensitivity is taken account of by adjustment of a grey wedge (34 Fig 2 not shown) or a diaphragm in front of the photo-resistor 20. Depression of the button 2 causes diaphragm blades 12 to open from the smallest aperture to an aperture appropriate for the illumination, the setting being indicated on a scale 32, Fig. 4, by pointer 4. Switch S 2  closes to make transistor T 2 , Fig. 5, conductive. Switch S 3  is operated to switch the photo-resistor 20 into the shutter timing circuit, and a switch S 4  switches in capacitor C. Driving disc 26 rotates until projection 26a engages lever 50 held by an armature lever 46. After a delay, depending on the charging time of capacitor C, an electromagnet 37 is de-energized, thereby releasing lever 46 and allowing disc 26 to return the shutter blades 24 to closed position. A calibration mark 58, Fig. 4, is provided to test the voltage of battery 15, Fig. 5, when photoresistor 20 is short circuited by closure of switch S 1 .

Title: Protective coating of semiconductor bodies
IPC: H01L23/29
Filed: 1957-08-19
Abstract: 864,297. Semi-conductor devices. HUGHES AIRCRAFT CO. Aug. 19, 1957 [Sept. 4, 1956], No. 26113/57. Class 37. A semi-conductor signal translating device such as a transistor, rectifier or photo-cell comprises a semi-conducting crystal of Si, Ge of one conductivity type having therein a region of opposite conductivity type separated therefrom by a rectifying PN junction, and a thin external coating of a hydrolysed organo-substituted silane material including a mono-functional organo-substituted silane, the silane material being polymerized into a silicone coating. The coating takes place after a preliminary etching step. After the crystal is cut and lapped it is preliminarly etched by known methods, e.g. by immersing in a solution of equal parts of HNO 3 , HF, and acetic acid, it is then rinsed in distilled water, boiled in a 5/50 mixture of acetone and methyl alcohol and rinsed in absolute methyl alcohol. It is now immersed in water to moisten it by adsorption, surplus water being removed with a filter paper. The Si crystal is now immersed in the silane solution mixture for one minute, the solution being agitated, e.g. ultrasonic agitation. The silane solution mixture may be a 1: 1: 2 mixture of methyltrichlorosilane, dimethyldichlorosilane and trimethylchlorosilane, the first two being polyfunctional organo-substituted and the third being monofunctional organo. Alternatively the first two can be phenyltrichlorosilane, diethyldichlorosilane (both polyfunctional) and the third, which is monofunctional, trimethylethoxysilane. In the hydrolysis HCl is split off and a polymerization chain forms, the reaction ceasing when the monofunctional silane joins a molecule of the other silanes present. The thickness of the protective film is 6 x 10-<SP>5</SP> cm. or less. If it is to be thinner than 6 x 10-<SP>5</SP> cm. the silane solution mixture is diluted with up to 90% of organic solvent, e.g. trichloroethylene. After removal of the crystal from the silane solution mixture it is baked, e.g. for 2 hours at 100‹ C. or 1 hour at 300‹ C., to drive off volatile materials and to complete the polymerization. The final product can be used in Si PNP fused junction transistors. Instead of immersing the crystal in the silane solution mixture, a silane vapour mixture can be passed over the crystal. The crystal may be irregularly shaped. A prior art device is also referred to in which the crystal is coated with silicone varnish and baked for 4 hours at 300‹ C. U.S.A. Specification 2,708,646 is referred to.

Filed: 1956-08-28
Abstract: 807,287. Tanks. ESSO RESEARCH & ENGINEERING CO. May 28, 1957 [Aug. 28, 1956], No. 26257/56. Class 69 (1). In a storage tank containing liquid of specific gravity less than water, a water seal is surrounded by a container comprising a perforated screen, whereby turbulence occurring in the stored liquid is not transmitted through the perforated screen in sufficient degree to cause displacement of the water 9 in the water seal. As shown in Fig. 1 the water seal comprises a downcomer 7 from the roof 4 of the tank projecting into water 9 contained in a tray 8. When water floods the roof of the tank it falls through the downcomer 7 into the tray 8 and slops over the side to descend through the liquid of less specific gravity, such as gasoline, in the tank. A gasoline inlet 2 is provided in the tank and a nozzle 3 is provided for the introduction of liquids to be blended with the gasoline. The nozzle is adapted to introduce these further liquids in such a way as to cause turbulence in the liquid contents of the tank and thus achieve maximum blending. The perforated screen may comprise a sheet of metal containing a series of holes or it may comprise a wire gauze. In both cases the total area of the perforations is not less than the cross-sectional area of the downcomer 7. The screen may be as shown in Fig. 3 or it may be spherical. Alternatively a perforated screen may be affixed to the top of the container 2.

Filed: 1922-09-30
Abstract: 207,656. Jackson, J. E. Evans-, (Hesser Maschinenfabrik Akt.-Ges., F.). Sept. 30, 1922. Paper tubes.-Paper and like tubes having one end closed are formed from rhombic-shaped blanks which are cut from an intermittentlyfed roll of material by a severing device disposed obliquely to the axis of the mandrel at the desired distance therefrom. The leading corner of the blank is secured to the mandrel by grippers, and after winding one end is folded in and the tube stripped off. The web of paper P, Fig. 1, is fed forward the desired amount by the intermittently driven rollers 1, 2 and a movable knife 6, Fig. 2, pivoted on the bolt 8 and operated through a system of levers by a cam on the main driving shaft A, co-operates with an edge on the table T to form the rhombic blanks B, a holding down device, not shown, being employed to hold the paper in position. A printing device may be used to imprint matter and consecutive numbers on the blanks, as at S. The leading corner of the blank B is engaged between the mandrel 20, which is supported at one end in a bearing 35, and a finger hinged within a recess in the mandrel, and held in position to grip and release the blank by a spring operated by a lever oscillated from the driving shaft. The blank is then wound on the mandrel 20, which is driven intermittently in one direction only by the gear shown in Fig. 1. A toothed sector 142 is oscillated about its axis 42<1> by a pin 43 running in an inclined circumferential slot in a barrel 108 keyed on the main shaft A, to turn the gear wheel 41 backwards and forwards. The forward motion only is transmitted to the gear wheel 37, by means of the pawl and ratchet 38, to drive the mandrel by a wheel 36 keyed to it. After winding the blank on the mandrel, the gripper finger is operated to release the blank, and a brake-shoe carried on a spring arm rides upon a disc 30 and brings the mandrel to rest. The bottom of the tube is then formed by four folders cam-operated from the driving-shaft A, one acting from above, another from below, and the other two from opposite sides, against the projecting end of the tube. A convex-headed punch 100 also drives from the driving shaft A by a linkage, next presses in the folded end of the tube against the concave end 210<1> of an ejecting rod 50 concentric inside the mandrel 20, and forms a tighter closure. A cam driven from the main shaft A reciprocates the ejector rod 50 through a system of levers to eject the finished tube from the mandrel when the process is repeated.
