Title: Improved means for obtaining proportional regulation of the flow of liquids and/or gases
IPC: G05D16/12
Filed: 1928-04-28
Abstract: 316,344. Candy, F. P. April 28, 1928. Mixing fluids in flow.-A method of adding a liquid or gas at proportionate rates to water or other liquid flowing through a Venturi tube or other resistance consists in producing liquid under pressure proportional to the difference be. tween the throat and full bore pressures and bringing the added fluid to the said liquid pressure. The Figure shows a valve device for obtaining the said liquid pressure. The device comprises a valve 38 actuated by a pair of leaky pistons 36, 37, the first subject to upstream pressure on its lower face and the second to throat pressure on its upper face. Water leaking into the chamber 45 which is connected by a pipe 34 with the diaphragm chamber of the gas valve accumulates until its pressure equals the difference between the upstream and throat pressures, when the valve 38 opens to allow the excess to pass to drain by way of pipe 35. The weight of the pistons is counter-balanced by a float 42 arranged in a chamber 43 supplied with water through a leak 40 and maintained full by an overflow 44. Diaphragms and adjustable leaks may replace the pistons and the valve may be arranged to control the supply instead of the exhaust from the chamber 45. According to the Provisional Specification, the main stream may pass through a Venturi tube and the added fluid first reduced to upstream Venturi pressure or the same pressure minus a constant, then passed through a dosage orifice and finally reduced to the Venturi throat pressure or that pressure minus the same constant. The pressure-reducing valves may be actuated by diaphragms subject on one side to the pressure of the added fluid and on the other side to Venturi pressure. Closed air vessels may be arranged in the pipes connecting the Venturi tube to the pressure-reducing valves. For dealing with high pressures, reducing valves may be inserted in these pipes. A form of reducing valve suitable for this purpose comprises a small weight-loaded piston working through a dividing plate in a closed casing receiving Venturi pressure on one side. A diaphragm may replace the piston.

Abstract: 435,245. Type - casting machines. PIERPONT, F. H., Oakfield, Redhill, Surrey, and MONOTYPE CORPORATION, Ltd., 43, Fetter Lane, London. April 26, 1935, No. 12508. [Class 100 (iii)] A carrier for a single matrix for use with single - type composing and casting machines has means for clamping in position matrices of different sizes and for adjusting the position of the matrix in two directions at right-angles, so that it can be accurately centred relatively to the mould cavity. The matrix X, Fig. 1, is clamped in a holder A in the form of a rectangular frame having an opening A<1>, against one face A<3> of which the matrix is held by a clamping - piece A<2> and screws A<4>, A<5>. The holder A is adjustable in one direction in an aperture in a slide B by means of a bell-crank lever D, one end of which enters a slot in the holder. The other end of the lever rests in a grooved collar on a screw D<4>, which is mounted in a threaded opening in the slide and can be turned by means of a knob D<5>. A spring pin D<8> mounted in the holder bears against one side of the aperture in the slide. A ratchet on the knob D<5> is engaged by a spring pin D' to prevent accidental turning of the screw. The slide B has ribs engaging in grooves in the sides of a carrier C, and is adjustable in a direction at right-angles to the movement of the holder A by means of a nut F turning on a screw F<1> fixed in the carrier. The movement of the nut is imparted to the slide through a latch G, which is pivoted to the slide and fits into a grooved collar on the nut. When the latch is opened, the slide can be withdrawn from the carrier. A ratchet on the nut F is engaged by a spring pin F<3>. The carrier is guided into position on the machine frame by side ribs C', C', a ribbed extension C<2>, and a rib B<2>. To facilitate the setting of the matrix in the holder A, the holder is placed on a positioning-block J, Fig. 6, a part of the floor of which is depressed, to form a gauging- surface for the matrix, which projects beyond the face of the holder. A pin J<4> carried by a spring-pressed arm J<3> holds the matrix in position.

Abstract: 595,435. Storage conveyers. WELDALL & ASSEMBLY, Ltd., and CONACHER, H. H. May 19, 1945, No. 12664. [Classes 78(i), 78(iii) and 78(iv)] In a car storage conveyer of the type having a remov.- able bottom, trucks moving in a circuitous track carry the car on top of the platform, and the ear together with platform is raised by a jack or the like into a storage compartment. In Figs. 2, 3, 4 motor-car at loading point L is received on raised platform 3 which is supported on electric truck 4 by jack 5. Truck 4 moves along " live rails 9 (connected on the " block " system) to a platformless storage holder 1 and upon lowering the jack platform 3 carrying car is left inside container being retained by projections 6 co-operating with ribs 8 on platform. Appropriate holder from any storage conveyer is then selectively and electrically rotated into position and then the truck elevates jack to contact the platform with desired car and carry both to unloading point D. Car is then run off and truck is reversed on turntable T2 and returned on second track to turntable T1 to start again. In the modifications of Figs. _ 6, 7, 9, platform 62 is carried on ground conveyer 60 in frame 61, Fig. 9, supported by plate surface 66 till it is underneath the appropriate storage holder la empty at its lowest position, Fig. 6.. Latter has longitudinal rods 51 to which are affixed support members 52 and also end arms 53 cooperating with end catch slides 54. Elevation of platfrom 62 by static jack 63 into holder la in collapsed position, Fig. 6, (right-hand, holder), secures arms 53 against catch slides 54, Fig. 6, (left-hand side) and lowering of jack leaves platform plus car retained in holder 1a. Appropriate storage holder is then lowered by rotation of the conveyer into position, platform 62 (elongated by engagement with slide 59 during the lowering movement) is raised and, projection 57 engaging with catch slide 54, Fig. 7, the reverse action takes place and the platform and car are lowered by the jack on to the ground conveyer and transported to unloading point. A plurality of static rams may co - operate with a plurality of platforms and holders at the same time, or they may be worked singly. The movement of trucks or horizontal conveyer and the jacks and holders may be automatically controlled. Horizontal conveyer is driven by sprocket wheels 67 and engagement of links 64 therewith may be rendered more effective by the addition of a flexible strand or chains. Specification 587,195, [Group XXXVIII], is referred to.

Patent GB-577279-A (GB)
Title: Improvements in or relating to the manufacture of organic sulphur compounds
Filed: 1940-08-12
Abstract: Thiols are prepared by catalytic hydrogenation of organic compounds containing a cyano group in the presence of hydrogen sulphide or a compound yielding the latter.  The hydrogenation catalyst employed is sulphactive and is a sulphide, sub-sulphide or polysulphide of a heavy metal of the Groups I, IV, VI, VII and VIII of the Periodic Classification.  Sulphides and polysulphides of copper, lead, silver, molybdenum, manganese, iron, cobalt and nickel are specified.  They may be used in admixture or supported upon kieselguhr, alumina or other carrier.  The nitriles may first be reacted with hydrogen sulphide to give thioamides, which are then hydrogenated.  In examples: (1) hydrogen is passed into an autoclave containing sulphur, lauronitrile and cobalt polysulphide, prepared by precipitation of a solution of cobaltous chloride with aqueous sodium polysulphide, whereby dodecanethiol-1 is obtained; benzo- and oleo-nitriles yield corresponding thiols; (2) hexadecanethiol-1, together with some palmitic thioamide is obtained by hydrogenating palmitonitrile in the presence of sulphur and cobalt sulphide catalyst; (3) a catalyst prepared by treating a methanol suspension of finely-divided pyrophoric cobalt metal with hydrogen sulphide is used in the hydrogenation of caprylonitrile; (4) caproic nitrile is treated with hydrogen sulphide and the product, after removal of unreacted caproic nitrile hydrogenated in the presence of cobalt sulphide to obtain hexanethiol-1; (5) hydrogen is introduced into an autoclave containing sebaconitrile, sulphur, benzene and cobalt polysulphide; decanedithiol-1 : 10 and a small quantity of 10-thiolcapricamide are obtained; (6) hydrogen is introduced into an autoclave containing 6-acetaminocaproicnitrile, sulphur, acetic acid and cobalt polysulphide.  Of the many nitriles specified, the following are typical: propionitrile, hydrogencyanide, pelargononitrile, oxalonitrile, glutaronitrile, polyacrylonitrile, naphthoicnitrile, phthalonitrile, hexahydrophthalonitrile, abieticnitrile and hydroxy, amino, aldehydo, keto and halogen nitriles, e.g. levulinonitrile and aminocapronitrile.  Dithiols may be produced from a  : b -unsaturated nitriles and aldehydo and ketonitriles.  Preformed thioamides may be used as starting materials, e.g. N-isobutylthiolauramide, N-dodecylthio-benzamide and N : N1 - di - n - octyldithioadipamide.  When a solvent is not used, polymeric polythioethers and polydisulphides are first formed.  In order to generate the hydrogen sulphide, besides sulphur, carbonbisulphide and sulphurdioxide may be used.  The ammonia formed in the reaction is preferably neutralized, for example with acetic acid or methylformate.  By mild oxidation the products are converted into disulphides and by energetic oxidation into sulphonic acids. Specification 574,936 is referred to.

Abstract: 684,071. Thermal switches. DANSK AUTOMATISK BRANDALARM AKTIESELSKAB. June 5, 1951 [June 6, 1950], No. 13273/51. Class 38 (v)] A fire alarm switch which may be mounted on a ceiling comprises a socket 1 attached to the ceiling, a housing 2 projecting downwards from the socket, bimetallic coils 15, 16 mounted in lateral recesses 13, 14 of the housing and connected to a spindle 17 which, through a further bimetallic coil 18 situated in an insulating compartment 9 operates switch contacts in the lower part of the housing, and an oilcontaining sheath 31 of heat conductive material which is slidable along the housing into a position in which it covers the recesses. The sheath 31 has radial heat conducting ribs 32 so that rise in temperature due to a fire causes the bimetal coils 15, 16 to respond more quickly than the heat-insulated coil 18 with the result that a finger carried by the coil 18 tilts a lever pivoted at its centre by two coil springs. An armature on the lower end of the lever is thus brought near a magnet and is attracted to it with a snap, causing two spring contacts to be moved away from their co-operating fixed contacts. Specifications 647,359 and 648,983 are referred to.

Abstract: 456,152. Grinding processes and wheels. COVENTRY GAUGE & TOOL CO., Ltd., Earlsdon, and HARLEY, S. J., Long Bend, Old Leamington Road, Stivichall, both in Coventry. May 4, 1935, No. 13332. [Class 60] To diminish the " loading " of grinding wheels and prolong the working time before re-dressing becomes necessary a relative vibratory movement of the wheel and work is produced during the grinding operation; alternatively, or in addition to the vibratory movement, the operative surface of the grinding wheel may be formed with relieved segmental portions m, Fig. 3, similar to those of a milling cutter or tap. Fig. 1 shows a grinding machine in which the work is mounted between centres on a table d which by means of a cam i is caused to oscillate rapidly about a longitudinal axis on trunnions e against the action of a spring k, thus causing rapid variations of pressure between the work and grinding wheel a. The amplitude of the vibrations may be sufficient to cause complete separation of the work and wheel, or merely periodic variations of pressure. A similar effect is produced by the use of a wheel in which the operative surface is formed in segments which are relieved over a whole or part of their length, such as that shown in Figs. 2 and 3, which may be used with or without a vibratory movement between the wheel and work. The invention is intended more particularly for use in the production or finishing of screw threads by wheels having thread-form serrations on the operative surface.
