Title: Improvements in mixing valves for hot and cold fluid
Inventor: LESOVSKY RODIN VOLTAIRE
IPC: G05D23/13
Filed: 1955-12-14
Abstract: 799,232. Thermally - actuated valves. ROBERTSHAW FULTON CONTROLS, CO. Dec. 14, 1955 [March 23, 1955], No. 35938/55. Class 135. In a mixing valve for hot and cold fluids, thermally responsive valve means controls the flow of fluid through only one of the inlets. The casing 10, 16, Fig. 2, has hot and cold fluid inlets 12, 14, respectively and an outlet 18. The inlet 12 ends in a wall 26 having two or more orifices 30. One end of a cylindrical valve member 32 is urged by a spring 52 against the wall 26. The other end of the valve member 32 has three inwardly bent fingers 34, Figs. 2 and 4, which engage a thermostatic actuating device 38 carried by a screw 44 adjustably located in a central tubular extension 28 of the wall 26. The casing 10 and the valve member 32 define an annular chamber 48 surrounding the mixing chamber 24. The inlet 14 is connected to the chamber 48 by a throat 50. The orifices 30 cause turbulence and a pressure drop within the chamber 24. In use the hot fluid passes from the inlet 12 into the mixing chamber 24 and when the fusible material in the device 38 expands the valve member 32 is moved to the right, Fig. 2, away from the wall 26, whereupon the cold fluid in the chamber 48 flows radially into the mixing chamber 24. The reduction in temperature of the fluid in the chamber 24 results in contraction of the fusible material and the spring 52 returns the member 32 towards the wall 26. The thermostatically actuated member 38 thus controls the amount of cold fluid entering the mixing chamber 24 and the temperature of the fluid from the outlet 18.

Title: Pumps and motors
IPC: F04B1/26
Filed: 1972-08-02
Abstract: 1395190 Fluid-pressure servomotor systems SPERRY-RAND CORP 2 Aug 1972 [22 Sept 1971] 36081/72 Heading G3P [Also in Division F2] In a pump displacement control system for a hydrostatic transmission wherein the reversible pump displacement is varied by differential area servopistons 112, 114 respectively connected to the delivery of an auxiliary pump 102 and to a pilot valve 116, the pilot valve 44 is controlled by pressures developed at intermediate points of two bleed circuits from the transmission high pressure line 106 (or 104). The bleed circuits are duplicated to provide both forward and reverse control. The first bleed circuit constitutes a command circuit and has fixed and variable restrictors 142, 144 (or 138, 140). The pressure intermediate the restrictors 142, 144 (or 138, 140) is applied to one end of the pilot valve 116. The second bleed circuit constituting a feedback circuit has two variable lamina flow restrictors formed by a plunger 132 (or 134) within a cylinder. The pressure at a point 141 (or 143) intermediate the restrictors is applied to the other end of the pilot valve 116. The plungers 132, 134 are connected by a linkage 136 to the pump displacement control member so that the laminar flow restrictors are varied equally and oppositely in response to variations in pump displacement. The pressure in the line 141 (or 143) is proportional to input torque and acts on the pilot valve 116 to maintain the torque constant for a predetermined setting of the command circuit. Variation of the command circuit variable restrictors 140 (or 144) varies the input torque to the transmission. If the pump delivery pressure exceeds a predetermined value it acts to change over an over-ride valve 150 which supplies circuit pressure to the servopiston 114 to effect a reduction in pump displacement. The maximum input torque may be limited by providing a pressure responsive relief valve between the restrictors in the command circuit. The system may additionally control a spring applied hydraulically released brake and a spring released hydraulically applied clutch through a valve 154 which, in the position shown, vents the clutch and brake hydraulic lines 160, 162. When the transmission pump is operative it supplies pressure liquid through a line 156 to change over the valve 154, and supply pressure liquid to the clutch and brake lines 160, 162. In Fig. 1 (not shown) a non reversible pump is controlled by command and feedback circuits similar to those described.

Abstract: 1,235,114. Releasable fastenings. BROOKHIRST IGRANIC Ltd. 18 July, 1968 [7 Aug., 1967], No. 36140/67. Heading E2A. [Also in Division H1] A latching push-button assembly comprises a base 10, a push-button 11 and a sleeve 12, the sleeve being partially rotatable relative to the push-button, when the push-button is depressed, to latch it in the depressed position. As shown, in a self-latching push-button assembly, the shaft 21 is secured against rotation and has, riveted to it, a latch plate 24 with the two slots sildable over projections 34, 35 on the inside of sleeve 12. Sleeve 12 normally tends to be rotated by a torsion spring 32 but is prevented from rotating by the slots in plate 24 engaging projections 34, 35. When pushbutton 11 is depressed, projections 34, 35 are disengaged from the slots and sleeve 12 is rotated by spring 32 until arrested by a stop. The absence of alignment between the slots in plate 24 and projections 34, 35 prevents retraction of the push-button. Sleeve 12 must be rotated by hand until the slots and projections are again in alignment before the push-button can retract, under the action of spring 26.

Title: Method of preparing metal oxides
IPC: C01B13/22
Filed: 1960-10-26
Abstract: <PICT:0972131/C1/1> A process for the production of oxides of metals (including silicon) by the vapour phase oxidation of the corresponding metallic halides comprises establishing a hot gaseous stream of an oxygen-containing gas, a separate annular stream of hot metallic halide vapour surrounding the oxygen-containing gas stream and a separate intermediate annular stream of an inert gas, introducing the oxygen-containing gas stream into an introduction zone, introducing the inert gas stream into the introduction zone from points surrounding and adjacent to the oxygen-containing gas stream, introducing the hot metallic halide vapour into the introduction zone from points surrounding and adjacent to the point of introduction of the inert gas into the introduction zone, the halide vapour stream being introduced inwardly towards the oxygen-containing gas stream and in a direction transverse to the direction of the oxygen-containing stream, and projecting the oxygen-containing gas, inert gas and metallic halide vapour into a reaction zone having a cross-sectional area greater than that of the introduction zone.  A further inert gas stream is preferably introduced into the reaction zone from points surrounding and adjacent to the point of entry, and substantially in the direction of flow of the mixture of oxygen-containing gas, inert gas and metallic halide vapour. This inert gas stream is preferably introduced in a plane perpendicular to the direction of flow of the reactants but with a mass velocity which has a radial component which is low in comparison with to the mass velocity of the reacting mixture so that on impinging on the reactant mixture its direction of flow becomes substantially that of the reactant stream.  A metal oxide and an organic compound may also be introduced into the reaction zone, the metal oxide preferably being produced in situ by adding a metal chloride to the oxygen-containing stream.  As shown in Fig. 3, a furnace B is equipped with a burner D comprising four vertically disposed and concentrically arranged tubes 200, 400, 600 and 800 which are spaced from each other to provide annular passages 1400, 1600, 1800 and 2000, respectively.  An oxygen-containing gas, an inert gas and a metallic halide are fed into annular passages 2000, 1800 and 1600 respectively, the gases being brought into contact with each other in introduction zone 3400.  The reactant gas mixture is then projected into reaction zone 3800 where it is contacted at the upper end with an outer stream of inert gas introduced through passage 1400.  The invention is illustrated by reference to the production of titanium dioxide, but other oxides, e.g. zirconium, tin and silicon oxides may be produced.
