Title: Improvements in or relating to compressors and turbines
Inventor: GRIFFITH ALAN ARNOLD
IPC: F01D5/06
Filed: 1949-02-15
Abstract: 678,085. Boundary layer control. ROLLSROYCE, Ltd. May 15, 1950 [Feb. 15, 1949]. No. 4171/49. Class 4. [Also in Group XXVI] An axial-flow compressor or turbine has blades with convex and concave surfaces and comprises a slot or slots or the like extending chordwise of the blade adjacent to the root or tip or both on the convex side of the aerodynamic surface, through which slot fluid can be sucked away, or through which a jet of air can be blown so as to prevent intrusion of fluid into the boundary layer on the convex surface of the blade. The rotor blades 15 have platforms 16, the surfaces 16a and 16b extending circumferentially from the convex and concave sides of the blades respectively, the surface 16b being stepped above the surface 16a and being cut away at 20 to permit overlapping of the surfaces, a slot being left between the convex side 15a of each blade and the edge 21 of the adjoining surface 16b through which fluid is drawn off into the crescent-shaped recess 23, through the channels 24 into the space between the blade fixing lugs 17. From here the fluid is drawn through the channels 25 and 26 in the lugs 17 and rotor disc flanges 18 respectively and thence through the ports 27 in the rotor spacer rings 14 to the spaces between the discs 13. The stator blades 11 have similar arrangements for drawing off fluid both at the radially outer and inner ends. At the radially outer ends, the stator blade platforms 12 are of parallelogram shape and have portions which overlap, the fluid being drawn off through a slot formed between a platform extension and the convex surface of a blade, through the channels 33 into the spaces between the casing flanges 10a, 10b. At the radially inner ends, the stator blades are spigoted into a shroud annulus 35 and inserts are provided between each pair of blades, fluid being drawn off through a slot between each insert and the convex surface of each blade and thence through the ports 27 into the spaces between the discs 13. Fluid sucked away from blades in a high pressure region of the turbine or compressor may be used for blowing away the boundary layer at a lower pressure region. In the case of hollow rotor blades, fluid sucked away from the root may be caused to flow through the blade and be employed to blow at the tip. Specification 621,544, [Group XXVI], is referred to.

Abstract: 463,344. Adhesive sheet materials. VORWERK, W. Feb. 12, 1936, No. 4228. Convention date, Feb. 12, 1935. [Class 140] [Also. in Group XXII] An adhesive material comprises a strip or sheet of non-fibrous cellulose, smooth on one side and coated with a non-drying adhesive mass on the other side which is grooved or patterned to increase its area so that tearing of the adhesive from the support, when unwinding from a coil, is obviated. As shown, the base material b is transversely grooved on one side and is coated on that side with a coloured or uncoloured, non-drying adhesive, e.g. rubber solution, the coated material being wound upon a cardboard tube c. The Specification as open to inspection under Sect. 91 describes also supports of metal foil and the use of a support of corrugated or zigzag shape, or a support roughened by a sand blast, wire brushes or etching; further, the use of fibrous material, the fibres on the non-adhesive side being covered, and of a support containing embedded fibres, the fibres on the adhesive side being partly released by roughening. This subject-matter does not appear in the Specification as accepted.

Title: Process for laying submarine pipeline
IPC: B29C48/09
Filed: 1974-01-30
Abstract: 1489186 Laying submarine pipe-lines BRITISH PETROLEUM CO Ltd 30 Dec 1974 [30 Jan 1974] 04241/74 Heading F2P [Also in Division B7] A process for laying a submarine pipe-line adapted to bring ashore crude oil which comprises forming a fibre reinforced pipe from a thermosetting resin within a submerged submarine vehicle capable of moving over the sea bed, weight coating the formed pipe within the vehicle and passing the coated pipe from the submerged vehicle. The fibre reinforcement is glass fibres and/or metal wire and the thermosetting resin is an unsaturated polyester or a polyepoxide. The weight coating consists of an aggregate bonded together with a thermosetting resin, preferably that used in the preparation of the pipe. The pipe may be surrounded by an outer collar thus defining a cavity between the pipe and collar in which the weight coating material is formed. The collar is of a plastics material having an Izod impact strength of greater than 2. There are a series of collars positioned and designed so that the coating material does not have uniform thickness along the pipe so that the coated pipe has increased flexibility. The collar may have internal ribs or projections and adjacent collars may overlap and form a protective cover over the weight coated pipe. In an alternative arrangement an outer cover formed from high density polyethylene is rolled over the pipe and weighting material is introduced between the pipe and the cover. The figure shows a submarine vehicle for laying submarine pipe-line and which is capable of controlled movement on or closely above the sea bed and comprises means 6 for forming a fibre reinforced plastics pipe, means 10 for weight coating the pipe and means, compression chambers 11, 12, for passing the weight coated pipe from the submerged vehicle. There is also means so that the extruding pipe can be directed upwards to the sea surface. The vehicle could be driven by nuclear power and has docking parts 14-17 to which supply pipes or supply submarines can be attached. A mandrel can be provided within the pipe that can be expanded to seal the pipe-line.

Title: A headlighting control system
IPC: B60Q1/14
Filed: 1967-01-30
Abstract: 1,124,863. Car lighting system. J.P. HAYDEN. Jan. 30, 1967 [Oct. 7, 1966], No. 4409/67. Heading G1A. In an arrangement for positioning a screen in the beam of each of the headlamps of a car to produce an unilluminated area in the front of an oncoming vehicle detected by the presence of its lights, the positioning of a screen is affected by a reversible motor having separate respective input circuits for the two directions and is adjusted in accordance with the position of the detected light. The motor may be of the step-by-step type. A chopper may be included in the path of a detected light beam to avoid response to static lights, and the pulsed sensor output is rectified to provide a control signal to a Schmitt trigger circuit whereby pulses from a multi-vibrator are directed by emitter-follower stages to one or other motor input drive circuit corresponding to a direction of desired screen movement. The multi-vibrator pulse frequency is controlled in accordance with the average rectified sensor output and enables rapid response to cars appearing suddenly by, for example, coming over a hill. Adjacent pairs of motor coils are sequentially energized to step the screen in correspondence with steps required to keep an aperture, in a graded opacity apertured vane, in the beam of an oncoming vehicle. The multi-vibrator pulses are applied to control the energisation of respective adjacent pairs of field coils through bi-stable transistor circuits described with reference to Fig. 13 (not shown). Motors having four coils are described, but multiple poles and coils, or gear chains may be used. The arrangement is made to fail safe if the chopper ceases to operate, and over-ride for flashing an oncoming undipped car may be provided.

Abstract: 354,703. Spray carburetters. SOC. ANON. DES CARBURATEURS ET APPAREILS CLAUDEL, Levallois - Perret, Seine, and VAUTHIER, M. E., Paris, both in France. Feb. 10, 1'930, No. 4467. Convention date, Feb. 27, 1929. Void [Published under Sect. 91 of the Acts]. [Class 7(iii).] In carburetters wherein an additional supply of fuel for acceleration purposes is obtained by air pressure produced by a pump actuated from the throttle valve, the air pressure is transmitted to ah auxiliary well or reserve chamber which feeds the nozzle. Fuel from a well c open to the atmosphere at 8, passes through orifices in a tube 5 to a main sprayer 2 at the lower end of a tube 4, the upper end of which carries a slow-running sprayer 3. The normal and slow-running mixtures are fed to the main air conduit 10 through ducts 9, 11 respectively. A small air pump 13 has a piston 14 adapted to be actuated against the action of a spring 15 by a tappet 17 on the throttle valve spindle. The space below the piston communicates through ducts 19, 20, 12 with the upper part of the well c. As the throttle is opened to accelerate, air is forced into the well and extra fuel is delivered to conduit 10. The air pressure may also be applied to the float chamber.
