Title: A projector for projecting slides of differing format
IPC: G03B23/04
Filed: 1967-12-20
Abstract: 1,204,720. Magazine slide projectors. BRAUN A.G. Dec.20, 1967 [Dec.22, 1966], No.57944/67. Heading G2A. A slide projector for projecting slides of differing size has for the reception of any magazine 5 carrying slides of a given size, a single magazine guide 2, there being a slide-feed device in the form of a pivoting claw 1 whose span and fulcrum position can be adjusted to suit any of the differing format sizes, for a given magazine. Each of the different sized magazines has a base formation which will engage the runner 2.1 and guide strip 2.2 of the guide 2. Claw 1 is formed in two parts, 1.1 and 1.2 each pivoting on spindle 3 and inter-connected through pin 6 and slot 7 to allow the claw to clear the magazine on the return stroke before indexing of the magazine along guide 2 takes place. Spindle 3 may be shifted by an eccentric wheel device from position K for small slides to a position M for larger slides wherein the stops 11, 12 on arm 1.1 are manually replaced by smaller, similar stops. The magazine indexing and slide-feed are motor operated. In a modification, stops 11, 12 are a permanent part of arm 1.1, and are adjustable dependant on the spindle 3 position. Reference has been directed by the Comptroller to Specification 909, 029.

Title: Improvements in or relating to methods of manufacturing components employing a high-energy beam of electromagnetic radiation
IPC: B23K26/14
Filed: 1969-12-01
Abstract: 1,255,374. Making electrical components; cutting by lasers. SIEMENS A.G. 1 Dec., 1969 [2 Dec., 1968], No. 58563/69. Headings B3A and B3V. [Also in Division H1] A method of manufacturing components e.g. resistors, thin film circuits and capacitors, comprises providing a carrier body with an overall layer of a material and a further coating having a non-reflective characteristic with respect to a beam of electromagnetic radiation which is used to burn off required areas of the layer of material, the coating having a thickness equal to or an odd multiple of d, where d is defined by the equation n.d= #/4 and n is the refractive index of the coating material at the wavelength # of the radiation used. A cylindrical ceramic body 1 has a carbon layer 2 and a varnish coating 3. A laser beam is focused to a point 8 on the carbon, the component body being rotated and moved axially so that a helical groove 9 is burned into the carbon. An air blast from nozzle 10 blows the molten parts of the component away from the point of burning. The coating 3 reduces the reflection of the radiation and thus accelerates the burning process. Chrome/nickel is a suggested alternative to carbon, and the coating may be of a solid fluorohydrocarbon or a phenolic resin polyesterimide varnish. The method may be used for metal, metal oxide, metal glaze layers and thin and transparent non-metal layers, e.g. of an insulating type.

Title: Improvements in or relating to processes for increasing the conductivity of insulating film

Filed: 1969-12-10
Abstract: 1285744 Modifying insulating films by coating with metals UNITED KINGDOM ATOMIC ENERGY AUTHORITY 19 April 1971 [10 Dec 1969] 60407/69 Heading C7F [Also in Division H1] The electrical conductivity of a thin insulating film is increased by superimposing a thin metallic film thereon and bombarding the metallic film with ions to sputter metallic ions into the insulating film. The insulating film may be an oxide or nitride, for example SiO, SiO 2 , Al 2  O 3  and may be deposited by evaporation or RF sputtering on to a substrate such as glass. The metallic film may be of Al, Au, Ag, Cu, Ni, Cr or Pb and may be formed by evaporation. An insulating film may be sandwiched between two metallic films on a substrate. The bombarding ions may be of Ar or Xe and are preferably as close in mass to the metal atoms as possible. The sputtering may be performed by sweeping a narrow beam across a workpiece or a slit mask and plasma source may be used. Surplus metal may be removed by etching or by sputtering but in some applications it may be left to form a contact. Contacts may be embedded in the substrate. The invention may be used to produce a resistor and capacitor in parallel and to make electrical terminal contacts for example through the insulating SiO 2  film on silicon transistors.

Abstract: 1,249,427. Colour television tubes. SONY CORP. 23 Dec., 1969 [7 March, 1969], No. 62733/69. Heading H1D. In a colour television tube wherein three coplanar beams pass through the centre of a common main focusing lens L M , Fig. 6, the source of the centre beam is located further from the lens than the sources of the outer beams to compensate for the different focusing effect of the lens on the beams so that all beams may be focused correctly at a common point on the screen. In Fig. 6 the centre cathode K G  is further away from the lens L M , and the grids G 1  and G 2  are shaped to provide the same cathodegrid spacings for the three beams. The protruding part of grid G 2  forms an auxiliary lens 13 for the centre beam and provides additional focusing for the centre beam, so reducing the distance by which the centre cathode must be displaced. The three beams are converged at the centre of lens L M  by an auxiliary lens formed by grids G 2  and G 3 . In modifications, Figs. 7 and 8 (not shown), the cathodes are directed towards the intersection point instead of lying parallel to the axis, and each cathode is surrounded by an individual cylindrical control grid G 1 . In these modifications the end surface of grid G 3  adjacent the grid G 2  may be shaped to be perpendicular to the axis (Fig. 8) or perpendicular to each of the three beams (Fig. 7).

Abstract: A heat pump (17) in combination with an air solar energy collector (2) has its evaporator (9) located in a duct (8) to which air heated by the solar collector (2) can be fed. The air is drawn past the evaporator (9) by a fan (10) driven by a motor (11) and is recirculated along duct 33 past the collector (2). The evaporator (9) can be excluded from the circuit by valve (6) directing the heated air along bypass duct (13). Heat storage devices (4) can thus be charged by being fed the heated air either along bypass duct (14) or through the solar collector (2). Fresh air can be fed to the duct (8) to prevent the evaporator reaching too high a temperature by opening throttle valve (16). The heat derived from the air circuit by the heat pump (17) can either be fed direct to a heat delivery system (29) for space or water heating or it can be stored, until wanted, in a heat storage device (25). <IMAGE>
