Title: Improvements in or relating to installations for detecting the presence of suspendedmatter in fluids
IPC: G01N21/53
Filed: 1931-08-25
Abstract: <PICT:0369514/III/1> An installation for detecting the presence of suspended matter in fluids comprises an electric commutator controlling valves whereby samples of fluid are drawn successively from a number of sources and passed through a common detector.  When suspended matter is present a switch operated by the detector disconnects the commutator and maintains all the valves in their existing positions.  A visual or other signal may also be operated showing which valve is open.  In the illustrated arrangement the commutator g energizes successively the magnets e<1> . . e<4> opening the valves a<1> . . a<4> connecting the several sources of fluid with the detector i.  Associated with each magnet are two contacts a<9>, a<10> which are closed when the magnet is energized.  The detector comprises a photo-electric cell i<3> connected through a thermionic amplifier 16 with a relay h, which becomes energized when suspended matter passes through the detector.  The action of the relay breaks the commutator circuit at g<62>, but the open valve a<3> is maintained open by the closing of contact g<66> which through wire g<67> supplies current to the magnet e<3> through its contact a<10>. The other valves remain closed.  The circuit of the visual indicator a<92> corresponding to the valve a<3> is also completed through the corresponding contact a<9>, the wires f<1>, a<93>, and the relay contact a<94>, and an audible alarm g<73> is also actuated by the closing of the contact g <71>. Specification 360,246 is referred to.

Filed: 1936-09-09
Abstract: 473,725. Disintegrating and mixing materials. KINGS PATENT AGENCY, Ltd. (Internationale Tobis Maatschappij N. V.) Sept. 9, 1936, No. 24586. [A Specification was laid open to inspection under Sect. 91 of the Acts, March 10, 1937.] [Classes 59 and 86] [Also in Group XX] In the production of multicolour screens for colour kinematography by mixing coloured powders and applying them to the film, the fineness of granulation of the powders is increased, and their mixture is rendered more uniform by the application of ultra-sonic waves, which cause the particles to vibrate at frequencies beyond or at the limit of the highest audible frequency. The oscillations may be applied to the powders before dyeing, and/or to the powder mixture before its application to the film. The powders may comprise mechanically-ground particles of rice-flour or colophony, dyed in batches red, green and blue. The powder, or mechanical mixture of powders may be put into a container k dipping into an oil bath a to which ultra-sonic oscillations are applied by immersing in the oil a quartz plate b enclosed between two electrodes d, e connected to the poles of an amplifier f connected to a generator of electric oscillations which are tuned to the natural frequency of the quartz plate by a condenser h. The Specification as open to inspection under Sect. 91 states also that advantage may be taken of the fact that mechanically-ground particles become charged electrically, to produce the ultra-sonic vibrations in the powder by placing the powder container between the electrodes of a generator of electrical oscillations, or by passing the film between the electrodes and blowing the powder mixture continuously on to it in the space between the electrodes. This subject-matter does not appear in the Specification as accepted.

A series of injection units (280), Fig. 1 (not shown), are movable in a circular path which coincides partly with the oval-shaped path of a series of injection moulds 206 connected together by links (262). Material is fed to the injection cylinders 40 by a screw pump 30 through passages 56 in a plate 26, and openings 52 in the cylinders 40. During injection, the cylinder 40 is moved downwardly to close the openings 52 and the supply of material is fed into an auxiliary cylinder 64. When the openings 52 are reopened a piston 66 is forced to the right against the bias of a spring (74) by means of a cam 90 (see also Fig. 1) and roller 88 and the injection cylinder 40 is recharged with material. Downward movement of the cylinder 40 and an injection piston 106 is effected against the bias of springs 104, 126 by means of a cam 150 and roller 148. Each mould comprises three portions 208, 212, 216 mounted on rollers 230, 232, 234 engaging in grooves 236, 238, 240 in side walls 202, 204 of a mould guide 200. The grooves 236, 238, 240 are arranged as seen. in Fig. 4 (not shown) -to open and close the mould parts at the appropriate positions. The upper. part 208 is raised before the lower part 216 is lowered and then the moulded article is removed by compressed air through an opening in the side wall 204. During injection the moulds are supported on rollers 252 carried by a frame 250 biased upwardly by springs 258. The walls 202, 204 combine with an intermediate wall 242 to form grooves 244, 246 receiving a cooling liquid. Pumps 264 draw liquid from one groove, pass it through passages in the moulds, and return it to the other groove. The pump 30 may be replaced by a number of pumps each connected to one or more of the injection cylinders, whereby articles of different materials or colours may be produced in different moulds.

Abstract: 1,061,378. Steam turbines. C.A. PARSONS & CO. Ltd. May 31, 1965 [June 15, 1964], No. 24780/64. Heading F1T. [Also in Division G3] A speed governing system for a steam turbine provides a linear relationship between percentage speed change and load. As shown, a governor valve 1 transmits a pressure signal proportional to turbine speed to a bellows 15 which actuates a pilot valve 13 controlling a servomotor 6. The servomotor 6 controls the pilot valve 20 of main servomotor 3 via floating lever 22 and is connected by lever 23 to a spool 16. The spool 16 controls the pressure within a bellows 14 abutting the upper end of pilot valve 13. In operation, a rise in pressure in bellows 15 moves pilot valve 13 to admit fluid to servomotor 6. The latter moves spool 16 to increase pressure within bellows 14 to return pilot valve 13 to its neutral position and at the same time actuates pilot valve 20 to move servomotor 3 to increase the opening of steam valve 2. The shape of port openings 18 controlled by spool 16 are such as to provide a non-linear relationship between governor valve pressure and movement of servomotor 6 which compensates for the non-linear relationship between steam valve opening and steam flow. Diaphragms may replace bellows 14, 15.
