Filed: 1958-06-06
Abstract: 887,333. Valves. VAILLANT, H., [trading as VAILLANT KOMM.-GES., JOH.]. June 6, 1958 [Aug. 23, 1957], No. 18088/58. Class 135. In a water deficiency safety device for gas water heaters in which the gas valve is operated by e.g. a diaphragm one side of which is connected to a stagnation point, e.g. a Venturi in the water supply channel, a slow ignition valve is built in the connection, this valve adjusting the cross-section of the connection automatically by an adjusting element acted upon by the water supply pressure against a spring. The lifting of the diaphragm to operate the gas valve is retarded by the water above the diaphragm being forced into the left-hand passage 9 and moving a check valve 24 in the form of a washer on to its seat 16<SP>1</SP>. Supply pressure at 18 acting behind piston 14 moves a needle 15<SP>1</SP> into the seat orifice 22 and washer orifice 25 to further restrict the flow of water through passage 9 whereby the opening of the gas valve is retarded. On closing the water outflow valve, flow through the Venturi ceases and the diaphragm moves down to close the gas valve, the downward movement occurring quickly as the needle valve is retracted by its spring 20 and the washer is moved to the left against a stopper and needle valve guide 23 to fully open the seat orifice 22. In a second embodiment the lower passage 9 is connected to the space above the diaphragm, the washer is dispensed with and the needle becomes a blunt plug valve.

Title: Improved oxidation resisting hydrocarbon and rubber compositions
IPC: C07F15/06
Filed: 1940-12-27
Abstract: 551,852. Hydrocarbon oil compositions; rubber compositions. STANDARD OIL DEVELOPMENT CO. Dec. 27, 1940, Nos. 18153 and 18154. Convention dates, Dec. 27, 1939, and Dec. 30, 1939. [Class 91] [Also in Groups IV and V] Oxidation resisting hydrocarbon compositions, such as lubricants, fuel oils &c. or natural or synthetic rubber compositions contain a small proportion of a polyvalent metal salt of a dihydroxy-dialkyl-diaryl sulphide or polysulphide or a polymer thereof, or a selenide or telluride analogue, one at least of the valencies of the metal being connected to an alkoxy group. Thus the type compounds for divalent metals comprise OH-AR-Sx-AR-O-M-OR or OR-M-O-AR-Sx-AR-O-M-OR, where OR is the alkoxy group and the other letters have the significance of Specification 547,972. For trivalent metals, additional series of compounds are possible including salts comprised by the type compound The aryl group may include more than a single benzene ring, such as diphenyl, or condensed rings, such as naphthalene, and phenanthrene. The alkoxy group is preferable methoxy or ethoxy, and the metal is preferably Fe, Ni, Co, Mg, Ca, Ba, Sr, Al, Cr, Mn, Pb, Sn, Zn, Cu, or Cd. The methoxy nickel salt of tertiary amyl phenol sulphide is specified. This salt may be obtained by adding a dry methanol solution of anhydrous nickel chloride to a methanol solution of tertiary amyl phenol sulphide to which has been added a solution of metallic sodium in absolute methyl alcohol. The precipitate obtained is separated and the filtrate then stripped of alcohol leaving a solid which is combined with the precipitate, the total solids being finally warmed with naphtha, cooled and again filtered The resulting solution is freed of naphtha and the desired salt of formula is obtained. The compounds or mixtures thereof, alone or in admixture with corresponding alkyl phenol sulphides, are preferably added to lubricating oils in the proportion of 0.01-2 per cent. by weight of the oil, 0.1-1.00 per cent. being generally sufficient. The additives inhibit oxidation, sludging, and ring- sticking, and also reduce carbon, lacquer, and resin formation; in greater concentrations they improve oiliness. The function is somewhat. selective according to the metal of the salt used. Other additives may be incorporated in the compounded oils, such as other anti-oxidants, dyes. soaps, pour inhibitors and sludge dispersers.

Void [Abridged as open to inspection under Sect. 91 of the Acts, June 28, 1932]. [Class 111.] House refuse before conversion into fertiliser is sterilized by the addition of a disinfectant and heat treatment at a temperature of 100‹ to 200‹ C. With apparatus as shown in Figs. 1 and 2, the refuse, mixed with disinfectant such as hypochlorite of lime, potassium permanganate or quicklime, is charged into wagons 7, having lattice or perforated walls, which move on rails through closed chambers 1, 8 successively. Superheated steam is supplied to the chambers 1 through a pipe 9 from a boiler 10, from which also air or hot gas is supplied through a pipe 11 to the chambers 8. Greasy condensation liquors separating in the chambers 1 are passed to a reservoir 12. A fan 13 draws the hot gas from the chambers 8 and returns it to the ashpit of the boiler. After leaving the chambers 8 the wagons are tipped into a ditch 15 from which the refuse is lifted by a bucket conveyer 16 to a classifying drum 17. From hoppers 18, 19, 20 below the drum 17 the refuse is passed by belt conveyers 21 to crushing apparatus 22. With the apparatus shown in Fig. 3 the process of treatment is a dry one. The refuse mixed with disinfectant is fed by a conveyer 44, crusher 45 and hopper 46' to a rotary sterilizing cylinder 27, heated by furnace 26. After treatment it is passed through a screen and disintegrator as with the other apparatus. Gas drawn from the cylinder 27 by a fan 40 may be passed through a cyclone separator 41. To permit of incineration of the refuse, a burner arranged near the end of the cylinder 27 is supplied with pulverized coal or liquid fuel from a tank 42. Combustible portions of the refuse may be used for heating the boiler 10 and in the furnace 26.

Abstract: 695,605. Press filters. HOFFMANN, J. Aug. 2, 1951 [Aug. 5, 1950], No. 18332/51. Class 46 Liquid is separated from mashes and solid.liquid mixtures of similar consistency such as fats, oils, and juices from vegetable or animal raw materials using press-filter hydraulically actuated pressure filter plates 5, 6, Fig. 1, firstly by a preliminary operation stage without movement of the filter plates 5, 6 and then by subsequent pressurefiltration stage in which the filter plates approach each other there being suction applied to the filter plates in both the stages. The suction is uniformly distributed over the full area of the plates. The solid-liquid mixture may be supplied to the filter chamber 9 under gravity from an elevated chamber 12 or from a compressedair loaded chamber. The pressure feeding the mixture into the chamber is less than the suction. The mixture is fed tangentially into the filter chamber 9. When the solid-liquid mixture is used at a high temperature the vaporized fluid extracted from the filter plates through the conduits 7 by suction created by a pump 15, is liquified in a condenser 16. The filtering medium of the filter plates, e.g. nickel mesh is supported on a ribbed surface forming channels 18, Fig. 2, which are closed at their ends by an annular ring 20 and communicate at one end through slits 21 in the ring 20 with a semi-annular duct 22 in communication with an air intake pipe 8 and similarly on the opposite half of the plate the ducts 18 communicate with a similar semiannular duct and with the suction pipe 7, Fig. 1, so that after each pressing stage, air can be drawn through pipes 8, duct 22, slits 21 into the channels 18 over the back surface of the filter plates for discharge through the pipes 7 carrying therewith any fluid particles adhering to the ribbed supporting surface and filtering medium.

Abstract: 1,187,516. Detectors. TEXTRON Inc. 19 April, 1968 [1 May, 1967] No. 18639/68. Heading H3Q. [Also in Divisions G1 and G6] A signal proportional to the magnitude E of that component of a complex electrical signal which has the same frequency as a reference signal, but unknown phase displacement # relative thereto, is obtained by producing from said reference and complex signals first and second signals V 1 , V 2 , proportional in magnitude to Ecos# and Esin# respectively, and from these producing a signal at least approximately proportional to V 1 cos# + V 2 sin#. In the embodiment described a signal in phase with the reference is induced in a centretapped secondary 18 of a transformer 13, a signal proportional to the complex signal is induced in a secondary 26a of transformer 35, and from these phase-sensitive diode detector circuit 31 produces at 44 a D.C. voltage proportional to Ecos#. A second similar circuit 32 produces at 47 a D.C. voltage equal to that at 44 but of opposite polarity and a diode OR gate 43, 46, selects that one of the voltages at 44, 47 having required polarity to constitute V 1 . A similar arrangement, supplied by a transformer 17 whose primary is excited 90 degrees out of phase with the reference, produces at 45<SP>1</SP> a second D.C. voltage V 2  proportional to Esin#. The signals V 1 , V 2  are applied to at least two summing circuits, each comprising a pair of input resistors, as 48a, 48b, connected to a summing junction, as 51. As shown, three summing circuits 48-50 are provided, the conductances of their input resistors being the ratios cos 15 degrees: cos 75 degrees, cos 45 degrees: cos 45 degrees and cos 75 degrees: cos 15 degrees. It is stated that the signal at the summing junction having the highest potential will, to a good approximation, be proportional to V 1 cos# + V 2 sin#. This signal is selected by diode gate 54-56 to provide Ecos<SP>2</SP># + Esin<SP>2</SP># at the output 57.
