Title: Turbine blade manufacture
IPC: F01D5/14
Filed: 1973-10-05
Abstract: 1440650 Making turbine blades GENERAL ELECTRIC CO 5 Oct 1973 [12 Oct 1972] 46709/73 Heading B3A A method of making a turbine blade having subsurface cooling channels comprises forming recessed grooves in the surface of a blade core, filling the grooves flush with an electrically conducting filler composition which includes a depolymerizable polymer vehicle whose monomer units have a boiling point of less than about 450‹ C., depositing a solid layer over the core and exposed filler surfaces to provide a blade skin, and removing the filler composition to leave clear channels. In an example, isobutyl methacrylate polymer is dissolved in toluene and a paste is formed by the addition of graphite powder of -325 to + 400 mesh size. After hardening of the filler in the grooves of the blade core the latter is prepared for electroplating, e.g. by ultrasonic cleaning. A layer of Ni is deposited on the core and the coated core is heated to 300‹ C. to depolymerize the polyisobutyl methacrylate. The graphite powder is then blown out of the cooling channels. Molybdenum, or other metal powder, may be used to make the filler conductive.

Title: Adjustable, Metered, Directional Flow Control Arrangement
IPC: F15B13/04
Filed: 1967-10-17
Abstract: 1,160,619. Valves. EATON YALE & TOWNE Inc. 17 Oct., 1967 [26 Oct., 1966], No. 47250/67. Heading F2V. [Also in Divisions F1 and G3] In an hydraulic system in which a pump 12 supplies fluid to one or other end of an actuator 10, 11 through a changeover spool valve 14, the velocity of the actuator is controlled by the degree of displacement of the spool 22 and a compensating valve 36 subject to the pressure drop across the valve 14 maintains the flow of fluid to the actuator constant by by-passing excess fluid through a port 56 and by restricting the flow through port 55 to the spool valve 22. The compensating valve 36 comprises a housing 42 having a bore 43 in which is slidable a valve piston 48 controlling communication between an inlet port 54 connected to the pump 12 and the ports 55, 56. One end of the piston valve 48 is urged by a spring 62 and by the pressure of fluid admitted to a chamber 63 connected through a line 35 and a shuttle valve 34 to whichever of the actuator inlet lines 30, 31 is pressurized. The opposite end of the piston 48 is subjected through passages 59, 61 to the pressure at the inlet port 54, whereby if the load on the actuator 10, 11 decreases or the pump outlet pressure increases the pressure drop across the spool valve 22 increases, causing the piston to move to the right. Movement of the piston to the right first connects the inlet port 54 to the by-pass port 56 and secondly a land 50 on the piston 48 restricts flow to the port 55. Fluid by-passed is utilized in a load circuit 57.

Title: Photographic reversal process
IPC: G03C7/28
Filed: 1962-12-19
Abstract: 967,036. Photographic reversal processes; dye-bleach processes. CIBA Ltd. Dec. 19, 1962 [Dec. 20, 1961], No. 47950/62. Heading G2C. A reversed image is produced in a photographic silver halide material of which the halide is predominantly bromide by developing the exposed material to a silver image, converting the silver to silver chloride and selectively removing the latter in a thiosulphate bath without removing the unexposed silver bromide, removal of the silver bromide being prevented by treating the material with a heterocyclic mercaptan at any time after the primary development but not later than during the action of the thiosulphate. The silver bromide remaining is then converted into a silver image in known manner. The mercaptan may be 2-mercaptobenzthiasole or 2-mercapto-benzimidazole. They may be used in a separate bath after the stop bath, or in the stop bath or thiosulphate bath or both. The stop bath may comprise acetic acid and sodium acetate. The primary silver image may be converted into silver chloride in a copper nitrate/ hydrochloric acid bath or in a potassium ferricyanide/sodium chloride bath. The invention may be applied to the silver-dye bleach process by including a bleachable dye in the light-sensitive silver halide material. After the formation of the reversed silver image according to the invention, the dye is bleached imagewise and the excess remaining silver removed by conversion into silver chloride in a copper nitrate/hydrochloric acid bath and fixing. An example is given of the production of a multi-colour image by the silver dye-bleach process.

Abstract: 1486893 Acoustic flow-detection HAUNIWERKE KORBER & CO KG 17 Oct 1974 [19 Oct 1973 23 March 1974] 48740/73 and 13020/74 Heading G1G [Also in Divisions A2 B8 and H1] The wrapping of a cigarette or other rod-like product of the tobacco industry is tested by applying sound waves to either the inside or outside of the cigarette or product and detecting any changes in the waves caused by faults in the wrapping. In the Fig. 2 system, cigarettes z held by suction on a conveyer drum 27 are brought in turn to a testing station at which sound from source 46 is passed via ducts 49, 52, 54 to the inside of a cigarette end. Sound from the other end is led by ducts 54, 52, 84 to a microphone 86. Flexible seals 38, 41 grip the cigarette ends and engage or disengage (under the action of cams 62, 67, camfollowers 61, 66, holders 56 and pistons 58) as the cigarette approaches or leaves the test station, respectively. Attenuation of the sound to below a level set by Schmitt trigger 89 is attributed to a faulty wrapping and causes air-jet 99 to eject the cigarette at a point downstream of the test station. The test and ejection are synchronized with the operations of a cigarette-making machine by use of timing pulse generator 80. In the Fig. 12 embodiment, a two-part enclosure 1003, 1004 temporarily surrounds a cigarette at the test-station, sound-waves from source 1036 are fed via ducts 1011, 1006 to the enclosure, and sound level is sensed by microphone 1043. In this case the sound waves are both applied and sensed outside the cigarette. Drum 1016 receives enclosure parts 1004 from drum 1038 and cigarettes from drum 1026. At B, parts 1004 and the cigarettes are transferred to drum 1027 where the test is made. At C the parts 1004 are removed and transferred, by drums 1017, 1038 including magnetic holders, back to drum 1016. At D the cigarettes are transferred to drum 1028. Modifications are described in which (a) sound is applied inside one end of the cigarette and simultaneously, in anti-phase, outside the cigarette to enhance sound energy transfer through the wrapping, (b) the sound is applied inside both ends and sensed outside or vice versa, (c) one end is blocked off and the sound is applied at the other and sensed outside or vice versa, (d) alternative end seals are used, (e) the sound source energizing signal is such that a standing sound wave is formed, the magnitude of which varies along the cigarette so that the test sensitivity is enhanced at critical regions, e.g. where a filter-tip is joined to the cigarette.
