Abstract: 1500208 Etching INST POLUPROVODNIKOV AKAD NAUK UKRAINSKOI SSR 18 Dec 1975 51760/75 Heading B6J Irradiation of a structure comprising a metal layer 2, a barrier layer 3 and an inorganic layer 4 causes interaction between the metal and inorganic layers with the resultant formation of pockets 9 of reaction products. The barrier layer which normally prevents such reaction permits interaction in the areas struck by the radiation. The barrier layer may also react or become absorbed into the reaction products in the irradiated areas. A backing layer 1 is preferably provided. The unreacted portions of layer 4 are then removed, e.g. by chemical etching, Fig. 5, and the unexposed portions of the barrier layer removed by etching, mechanically or by thermal sublimation. An electric field may be applied to the structure during exposure to promote interaction of the layers. The metal layer 2 may then be removed by etching where not protected by the reaction products 9. The products 9 may then be removed mechanically, by etching or thermally. The layer 4 may be gaseous or liquid rather than solid as shown in Fig. 3. A further layer may separate the layers 1 and 2 and this layer may also be selectively removed by etching and the overlying areas of layer 2 also removed. Exemplified for layer 2 are silver, copper and metal alloys, for layer 3 are Au, Zn, Cd, Mg, Al, Ga, In, Tl, Si, Ge, Sn, Pb, As, Sb, Bi, Ti, V, Cr, Mn, Fe, Co, Ni, Mo, Ta, W, Os, Ir, Pt and their alloys, oxides, sulphides, tellurides, halides, and phosphides, polyethylene, polystyrene, polypropylene, polymethacrylate, polycarbonate, polyvinyl chlorides, polytetrafluoroethylene, epoxy resins, colophony and anthracene, for layer 4 are given sulphur and selenium and compounds thereof (specific compounds are listed).

Filed: 1975-12-18
Abstract: 1507572 Plastics bottles A R RAUSING 18 Dec 1975 [3 Jan 1975] 51915/75 Heading B8D [Also in Division B5] A disposable bottle is made by wrapping and lap-seaming a heat-shrinkable foamed plastics blank 3 to form a cylindrical tube, placing the tube over a mandrel 18 having a tapered or necked end 6, heat-shrinking the end portion of the tube located about the necked end into bottle-shaped conformity therewith, and sealing a closure disc 14 to a flange 12<SP>1</SP> formed on the other end portion of the tube. The blank comprises two heat-shrinkable layers 1 of foamed plastics, e.g. polystyrene, and a plastics, metal foil, glass, or paper reinforcing intermediate layer extending only over the intermediate part of the width of the blank forming the cylindrical bottle body portion 11. An impermeable layer 21 of polyvinylidene chloride or an acrylonitrile plastics is also provided over one side of the blank. The inturned flange 12<SP>1</SP> is formed by inserting a collapsible mandrel or former 13 into the open end of the tube after the latter has been removed from the mandrel 6, and heating the lower end of the tube so that it folds inwardly on shrinking. The former 13 is then collapsed and removed through the opening defined by the inturned flange. The disc 14, which may be formed of a laminate having the same construction as that of the intermediate portion of the blank 3, is heat-sealed or adhered to the flange. The rim 10 of the bottle is beaded and rendered planar by pressing a heated-tool 16 against the rim. The bottle is completed by a cap 19 attached to the bead and heat-sealed.

Title: A gas-turbine plant
IPC: F02C9/54
Filed: 1965-12-09
Abstract: 1,065,309. Gas turbine plant; turbines, axial-flow compressors. BROWN, BOVERI & CO. Ltd. Dec. 9, 1965 [Dec. 11, 1964], No. 52268/65. Headings F1C, F1G and F1T. [Also in Division G3] A gas turbine plant comprises a compressor 1, a combustion chamber 2 and a turbine 3 in which the fuel supply is controlled by a valve 10. A fluid control system adjusts the stator blades of the compressor and turbine and the valve 10 in response to changes in load to maintain the gas temperature before the turbine substantially constant. The fluid system has several supply inlets 11 and exhausts 13. The load on the plant is measured by a governor 15 which acts through a valve 16 to control the pressure in conduit 14, this pressure normally acts through a relay valve 18 on piston 20 to control the fuel valve 10. The pressure in conduit 14 also acts on a pressure ratio regulator 17 to provide a pressure in a conduit 21 proportional to the pressure in conduit 14, the pressure in the conduit 21 acting to adjust the blades 5, 6 of the compressor and turbine. The piston 7 of the blades 5 is actuated directly by the pressure in the conduit 21 while this pressure acts on a piston 27 of a relay valve 29 to provide a pressure to actuate the piston 8, this pressure providing a feedback by action on piston 26. The temperature of the gas before the turbine is sensed by a probe 45 which acts on a leak valve 46 to control the pressure in bellows 51. The bellows 51 actuates a valve 53 to provide a pressure in conduit 30 proportional to the temperature. Normally, the variation in load adjusts the fuelair ratio as above and maintains the gas temperature constant but if this temperature varies, the pressure in conduit 30 acts on the regulator 17 to adjust the pressure ratio of conduits 14, 21. The regulator 17 comprises a bellows (31), Fig. 2 (not shown), subject to the pressure in conduit 14 to adjust a leak valve (37) with a moving seat (38), to set the pressure in conduit 21. A fulcrum (35) of a lever (34) is varied with changes in pressure in the conduit 30 acting on a bellows 40 and cam (42). When the blades are fully open and the gas temperature continues to rise a valve 18, which normally connects conduits 14 and 19, is actuated by the pressure difference in conduits 14 and 30 to connect the conduit 30 to 19, thus the fuel valve 10 is then controlled directly by the temperature. Similarly a valve 22 which normally connects conduits 21 and 23 may be actuated by a manually controlled valve 62 to connect conduits 63 and 23 to provide a manual control of the blades. Safety relays 20, 65 are provided to exhaust the control systems by an excess-speed contact 66, a magnetic valve 67 or a manual valve 68.

Title: Combined circulator and mixer for hot water heating systems
IPC: F04D29/42
Filed: 1974-12-06
Abstract: 1487771 Mixers KLEIN SCHANZLIN & BECKER AG 6 Dec 1974 [13 Dec 1973] 52932/74 Heading B1C [Also in Division Fl] A combined circulator and mixer for a heating system comprises an impeller 3 drawing water from a mixing chamber 8 within the pump and casing 1 and discharging it via a heating flow spigot 10; a boiler return spigot 9 below the mixing chamber; and horizontally extending spigots 11, 12 which may serve for heating return and boiler flow respectively. Members 6, 7 which are screwed into the casing 1 to provide a restrictor 5 and a non-return valve 4 respectively can be interchanged to enable the roles of the spigots 11, 12 to be interchanged. A Y-shaped wall 13 having upper links separating the mixing chamber 8 from the spigots 11, 12 and a lower limb 14 dividing the spigot 9 into two parts communicating with the spigots 11, 12 respectively has an air-filled insulating chamber 19. The speed of the driving motor 2 is controlled by a temperature sensor. If there is no heat demand, so that motor speed and pump delivery are low, the non-return valve 4 stays closed and the impeller 3 draws cooled water from the heating return via the restrictor 5 into the mixing chamber 8 and delivers it back to the heating system. Water from the heating return, being cooler than water in the boiler and therefore of a higher specific gravity, settles in U-shaped passage 17 and blocks the flow of hot water from the boiler circuit. If heat demand rises, producing an increase of impeller speed and therefore of heating circuit flow, the pressure drop produced by the restrictor 5 increases and the pressure in the mixing chamber 8 falls. When the latter pressure has fallen sufficient below the pressure in the boiler circuit, the non-return valve 4 opens to communicate the boiler circuit with the heating circuit, the mixing ratio of the hot and cooled water in the mixing chamber 8 being determined by the valve 4 and the restrictor 5. The presence of the limb 14 within the spigot 9 provides an injector effect whereby some of the water from the boiler flow passes to the boiler return. The fixed restrictor 5 may be replaced by an adjustable throttle valve, Fig. 3 (not shown). The four-way mixer can be converted into a three-way mixer by means of a plug 20 which closes the spigot 9 and abuts the limb 14 to prevent communication between the spigots 11 and 12. The boiler return line is in this case connected to the heating return line.
