Title: Apparatus for and method of applying protective coating material to the inside of a pipe or the like
IPC: B05B1/30
Filed: 1948-01-08
Abstract: <PICT:0642777/III/1> <PICT:0642777/III/2> <PICT:0642777/III/3> <PICT:0642777/III/4> Apparatus for applying coating material to the inside of a pipe comprises an applicator head movable through the pipe and having a nozzle through which coating material can be sprayed, a conduit through which coating material can be circulated from the supply to the head and back to the supply, part of which conduit constitutes means for moving the head through the pipe, and means for circulating the said coating material under spraying pressure. Referring to the drawings, the coating apparatus comprises a tank 35 from which liquid is withdrawn by pipe 43 and passed through flexible hose 38b, rigid hose 38a, applicator head 10, rigid hose 39a, flexible hose 39b and so back to tank 35 which may be heated by burner 37.  Hose 38a is attached to bore 25 in applicator head 10 and communicates via port 27, chamber 12, port 28 and bore 26 with hose 39a so that when spraying 24a holds valve head 22 closed, coating liquid circulates freely through these lines. Adjustment of valve 42 on hose 39a serves to build up pressure in chamber 12. Conduit 20 leading to the spray head is brought into communication with chamber 12 by the backward movement of actuator wire 34 fitted in opening 32a of plate 32 spanning rods 30 which pass through the applicator head openings 31 to cross-head 29, which head then presses against valve stem 21 moving valve head 22 and opening entrance to conduit 20.  A spray nozzle 19 may fit into conduit 20 and the applicator head may be supported on shoe 51 for ease of movement.  In the modification of Fig. 9, no actuator wire is required.  Here spring 24a operates from outside the head to maintain valve head 22 shut, but as the pressure of liquid builds up inside chamber 12, piston 21x is forced backwards and spraying commences.

Title: Improvements in fuel systems particularly for gas turbine engines
Inventor: WHITEHEAD JOHN PARKIN
IPC: F02C9/16
Filed: 1959-01-07
Abstract: 907,324. Supplying liquid fuel to burners. DOWTY FUEL SYSTEMS Ltd. April 7, 1960 [Jan. 7, 1959], No. 652/59. Class 75 (1). [Also in Groups XXVI and XXIX] In a liquid fuel supply system for the spill burner of a gas turbine engine a throttle valve is arranged for hydraulically balanced linear movement and the valve or a member associated therewith is rotated to reduce frictional resistance to movement. In Fig. 2 (not shown) a valve member 8 is slidably mounted in a sleeve 37 mounted for rotation in a bore 38 and rotated constantly by a gear 35 on a layshaft 34 driven by the engine. A further valve member 9 is slidably mounted in a rotary sleeve 39 driven by a gear 36 on the layshaft. Fig. 1 shows the valves 8, 9 but without the rotary sleeves. The valves control the spill flow of fuel from a burner 3 to the inlet of a pump 1. The valve 8 slides in a bore 7 and is controlled by a flyweight governor 12 loaded by a spring 13 loaded by a rack and pinion 14 actuated by a throttle lever 16. A land 21 on the valve 8 co-operates with a port 19 to control the flow of spill fuel from a pipe 4 to a passage 28. The valve 8 carries a damper piston 17 having passages for the flow of fuel from one side to the other. The other valve 9 comprises a tube slidable in the bore 7 and provided with a pair of tapered ports 25, 26 adapted to overlap with ports 23, 24. The tube is moved by a lever 29 controlled by an evacuated bellows 31 and an opposed bellows 32 in connection with compressor output pressure or a function of compressor output and air intake pressures. For steady running the land 21 throttles the flow of spill fuel to the port 19 and thence by passage 28 to the tapered port 26. The spill fuel flows through the tube valve 9 to a pipe 6 extending to the inlet of the pump. When the lever 16 is moved to increase the speed, the land 21 cuts off the flow of spill fuel to the port 19 but spill fuel continues to flow along a by-pass pipe 27 to the other tapered port 25. The valves 8, 9 are connected by a spring 11 which transmits to the valve 8 a force dependent on the pressure sensed by the bellows 31, 32. In another arrangement the fuel is controlled by a pair of throttle valves ineluding rotary drive to reduce friction, the valves being connected either in parallel or in series for independent adjustment by different signals. Specification 813,939 is referred to.

Title: Improvements in the copying of sound records
IPC: F16N13/14
Filed: 1934-01-09
Abstract: 421,503. Photographic printing processes. PHILIPS - MILLER NAAMLOOZE VENNOOTSCHAP, Emmasingel, Eindhoven, Holland. Jan. 9, 1934, No. 801. Convention date, Jan. 16, 1933. [Class 98 (ii)] [See also Group XXXVIII] Relates to the photographic copying of sound records that are mechanically produced in such a manner as to be adapted for optical reproduction. According to the invention, in order to avoid halation or diffraction effects, such records are copied by photographic printing by means of ultra-violet light or rays in the extreme violet region of the spectrum (rays having wavelengths above 4000 Š being excluded). The use of the invention for copying a sound record made by cutting away, with a V-edged chisel, parts of an opaque top layer and an intermediate soft layer on a carrier made of celluloid or the like is described and shown. In the Figure, the print film 14, having a sensitized top layer 15, is shown in contact with an original record film in which a groove having width and depth variations has been cut in an opaque layer 11 and in a soft intermediate layer 12. The ultra-violet rays used for printing are shown as parallel vertical lines which indicate that no diffraction is caused by the sharp wedgeshaped edges of the sound groove. The invention is useful for obtaining, by successive copying from an original negative, another negative that can be used repeatedly for obtaining further copies.

Patent GB-596591-A (GB)
Title: Improvements in or relating to inorganic oxide particles of spherical shape and their manufacture
IPC: B01J21/12
Filed: 1945-01-11
Abstract: <PICT:0596591/III/1> Inorganic oxide particles of spherical shape are produced by passing a sol of at least one difficulty reducible oxide capable of forming a hydrogel in droplet form through a fluid suspending medium and regulating the pH of the sol and the suspension time of the droplets so that they set while still suspended to a firm hydrogel having a spherical shape, and subsequently ageing the particles for at least six hours before drying them.  The sols employed may be of silica, alumina, titanium oxide, zirconia, thoria or ceria, or of mixed oxides, e.g., silica-alumina.  The suspending medium may be liquid, the droplets moving upwardly or downwardly therein or constituting an emulsion with the liquid, or gaseous, and in this case, the sol may be sprayed into a rising air stream. Suitable suspending liquids are kerosene and the oil known under Registered Trade Mark "Nujol."  For emulsions, kerosene, or carbon tetrachloride diluted with a hydrocarbon, with an emulsification agent such as resin or pitch may be employed.  The pH varies from 6 to 10 for silica sols produced by the acidification of water glasses, from 4.3 to 7 for silica sol formed by the hydrolysis of say ethyl orthosilicate, and from 4.5 to 7 for alumina sols produced by the addition of aluminium amalgam to water, or by precipitation of alumina from aluminium salts, washing, and redissolving in say acetic or formic acid. Ageing may be for 6-24 hours, either in air or in water, or in a solution of pH 2 to 7, or 7 to 8, or in the organic suspending liquid.  Drying of the particles is generally below 350 DEG C., infra-red radiation being advantageously employed.  The particles are suitably calcined at 350-900 DEG C.  Catalysts suitable for cracking, reforming and dehydrogenation of hydrocarbons may contain other active compounds introduced into the sol prior to the formation of the spherical particles, or by impregnating the wet or dry spheres.  Thus, a compound of chromium, vanadium or molybdenum, e.g., ammonium molybdate, may be added to an alumina sol; or dried spheres of silica may be impregnated with an aluminium salt solution, and then heated.  Other catalysts mentioned are alumina-chromia or alumina-molybdena containing a small amount of magnesia, and silica-alumina containing zirconia, thoria or boron oxide.  A suitable apparatus comprises vessels 1, 5 for, for example, sodium silicate and hydrochloric acid, a mixing vessel 4 and a chamber 11 containing kerosene &c. through which the droplets fall.  The spherical particles are swept away by a current of oil from pump 13 to separator 16, the oil being recirculated.  Specification 576,058 is referred to.
