Title: Fluid control valve
IPC: F16K1/24
Filed: 1972-09-29
Abstract: 1402004 Valves KOBE STEEL Ltd 29 Sept 1972 [30 Sept 1971] 45039/72 Heading F2V A valve comprises a valve closure disc member 3 freely mounted on an eccentric portion 2<SP>1</SP> of an operatng spindle 2, the closure member having blocks 4 which house a guide pin 9 urged outwardly, the operating spindle carrying a disc 7 having an aperture 15 and a second guide pin 8 therein, and the valve body having a groove 16 therein such that when the valve is closed (se Fig. 5) the pins 8 and 9 and groove 16 are out of alignment; on initial rotation of 90 degrees of the spindle, the pin 9 is carried into alignment with the groove 16 by virtue of the displacement of the closure member due to the eccentric portion of the spindle and the same rotation of the spindle causes the pin 8 to align with the pin 9 (see Fig. 6). The pin 9 urges the pin 8 into engagement with groove 16 so that the closure member 3 is locked to the spindle 2. Further rotation of the spindle causes rotation of the valve closure member to the open position (Fig. 7, not shown). The blocks 4 may also house pins 10 which prevent the valve member from rotating during the initial opening movement by co-operating with a groove 17 in the valve body

Patent GB-453238-A (GB)
Abstract: 453,238. Gyroscopic apparatus. BENDIX AVIATION CORPORATION, 105, West Adams Street, Chicago, U.S.A. May 4, 1935, No. 13343. Convention date, May 5, 1934. [Class 97 (iii)] Means are provided for adjusting an azimuth indicator, e.g. a card, controlled by a directional gyroscope independently of the gyroscope to set a predetermined course. In the form shown, the air driven rotor 6 is pivoted in a horizontal gimbal ring 14 pivoted in a vertical ring 16, pivoted in turn about a vertical axis in the air-tight casing 7 made of cast aluminium or a phenolic condensation product. Air is withdrawn from the casing 7 and is sucked through apertures 24 first into a chamber 26 formed by a cup-shaped member 27 on the vertical ring. Here the inrush of air tends to lift the member 27 and vertical ring and relieve the pressure on the thrust bearing 18. From the chamber 26 the air then enters the passage 28 in the vertical ring through apertures 29 and passes to a driving nozzle 21 fixed in the ring 14. The driving jet normally acts in the plane of the vertical ring 16 but if the ring 14 deviates from a position perpendicular to the ring 16 the jet exerts a reaction about the vertical axis of the ring 16 and precesses the gyro back to the normal position. An annular indicating card 31 with an upwardly extending flange 33 is attached by arms 34 to a bevel gear 35 journalled on the ball bearing support 20 of the vertical axis and normally rests in frictional engagement with an annular member 36 carried by the vertical ring. In this position the card 31 is carried by and turns with the vertical ring. In order to effect an adjustment a plunger (not shown), carrying a conical pinion and extending out of the front of the casing 7 is pushed inwards whereupon the pinion because of its taper causes the bevel gear 33 to be moved axially on the support 20 and the card 31 to be lifted clear of the annular member 36. The card may then be adjusted to a predetermined course independently of the gyro by turning the plunger. Alternative means for maintaining the ring 14 perpendicular to the ring 16 comprise oppositely directed air jet orifices 42, 43, Fig. 5, in the ring 16 normally closed by arcuate vanes 44, 45 on the ring 14.

Abstract: 991,749. Wiper assembly for a film evaporator; molecular stills. VITAMINS Ltd. Nov. 28, 1962 [Dec. 29, 1961], No. 46681/61. Heading B1B. Liquid is evaporated by distributing it in the form of a film on a heated surface where the film is repeatedly renewed by a plurality of moving wiper members mounted on a flexible conveyer belt. The wiper assembly is moved over the surface in a direction at right angles to the direction of motion of the conveyer belt, so that the wiper members agitate the liquid film in two different directions simultaneously. In the evaporator shown, the liquid to be evaporated is distributed as a film upon a horizontal annular heated surface 10 from a gutter 40 by three wiper assemblies. Each radial suport arm 108 carries a conveyer belt 102 fitted with wiper members 100, and is rotated about the vertical axis of surface 10. A spiral guide rail 118, mounted on surface 10, passes through the aperture between two adjacent wiper members on each conveyer belt, thus causing these wiper members, and the lower section of the conveyer belt, to move towards the outer edge of surface 10 when the support arm 108 rotates in the direction shown by arrow 120. During the movement of the film of liquid over the hot surface, some of it evaporates. The residual liquid finally flows from the outer edge of surface 10 into gutter 18<SP>1</SP>. The wiper members 100 are preferably made of a resilient material having a low coefficient of friction with the heated surface, such as polytetrafluoroethylene. Also described is an evaporator wherein the. single spiral guide rail on the heated surface is replaced by a number of short spiral guide rails. A downwardly-facing, horizontal condenser surface may be mounted above the evaporating surface, thereby forming a molecular still. Specification 991,747 is referred to.

The group R is preferably a C 3-8  cycloalkyl group or a monocyclic heterocyclic group having 5-7 ring atoms and one or more identical or different hetero atoms, for example groups of the following formulae wherein Z is O, S, in which R 1  is H, C 1-6  alkyl, aryl, aralkyl or aryloxy carbonyl. Reactive derivatives of the acid (VII) may be the acid halide, azide, anhydride, mixed anhydride or the reactive intermediate formed from the acid and a carbodiimide or carbonyldiimidazole. Esters of the compounds (I) include those wherein one or both of the carboxyl groups (i.e. the α-COOH and the 4-COOH group) are esterified. Benzyl hydrogen cycloalkylmalonates wherein the cycloalkyl group is cyclopropyl, cyclopentyl, cyclohexyl, and cycloheptyl are prepared by converting an appropriate cycloalkylmalonic acid to the acid chloride and reacting the latter with benzyl alcohol. The benzyl hydrogen cycloalkylmalonates are then converted to their acid chlorides by reaction with thionyl chloride. Benzyl hydrogen 2-tetrahydropyranylmalonate is produced by treating 2-tetrahydropyranylmalonic acid with an ethereal solution ofphenyldiazomethane prepared by reacting N-nitroso- N-benzyltoluene-4-sulphonamide and sodium methoxide in methanol and ether. Tetrahydrothiophen - 1,1 - dioxide - 3 - ylmalonic acid is treated with ethereal diazomethane to give benzyl hydrogen tetrahydrothiophen - 1,1 - dioxide-3-ylmalonate which is then converted to the acid chloride by treatment with thionyl chloride. 4-Tetrahydrothiapyranol is reacted in dry pyridine with benzenesulphonylchloride to give 4-tetrahydrothiapyranyl benzenesulphonate which is reacted with sodiodiethyl malonate to produce diethyl-4-tetrahydrothiopyranyl malonate. The latter is then hydrolysed with ethanolic NaOH to tetrahydrothiapyranyl-4-malonic acid which is converted to its acid chloride by treatment with oxalyl-chloride. Reference has been directed by the Comptroller to Specification 1,004,670.

Filed: 1973-10-10
Abstract: 1449637 Stop- and release-devices for rotary members; definite positions PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 10 Oct 1973 [13 Oct 1972] 47291/73 Heading F2E The invention in its broadest aspect is exemplified by the following description. Figs. 1 to 4 are underneath views of Fig. 5. As shown in Figs. 1 and 5, a knob 9 located on a mounting plate 1 has a control spindle 5 extending through the plate 2, the knob and spindle being rotatable with, and also rotatable relative to, a drum 3. The lower end of spindle 5 has lateral projections 35, 35<SP>1</SP> which retain a slide 13 and, as best shown in Fig. 4, can move the slide by stop surfaces 37, 37<SP>1</SP> (see below). The slide has slots 31, 33, 31<SP>1</SP> in which are located a pin 11 extending down from the drum, the spindle 5, and a further pin 11, respectively; it also has stepped arcuate surfaces (one shown at 19, Fig. 4) at one end which may be aligned with arcuate surfaces 21, Figs. 2, 4, formed in a cutaway portion of the drum. A latching pin 23 on a latching lever 25 pivoted at 27 is urged constantly into engagement with one or other of surfaces 19, 21, by a spring 29, and in the "off" position of Fig. 1, a stop roller 41 mounted by a spindle 53, Fig. 2, on a slide 43 is urged by a spring 47 into a cavity 39 of the drum. In operation, if knob 9 is rotated from the Fig. 1 position in the direction 49, Fig. 2, the slide, and hence the drum, rotate with it, and pin 23 eventually engages a latching cavity 51 formed at the right of the end of the slide. When the knob is released, the assembly is retained in the Fig. 2 position because though the drum is being urged by spring 47 clockwise via roller 41, whose spindle 53 lies within the angular extent of cavity 39 (see flank 55), the drum is retained by pin 23 engaging slide 13. The knob may be rotated further in direction 49 to the Fig. 3 position, where pin 23 engages a stop surface 61, and the knob is retained to hold this position. On release of the knob a spring, not illustrated, returns the assembly to the Fig. 2 position. To regain the "off" position, from the Fig. 2 position, the knob is rotated with increased force in direction 49<SP>1</SP>, whereupon the spindle 5 rotates relative to the drum so that one projection 35<SP>1</SP> retracts the slide against the force of the springs 15 by means of one stop surface 37<SP>1</SP> until surface 19 is aligned with drum surfaces 21, Fig. 4. Thereafter, the drum rotates also, bringing slide surface 19 into contact with pin 23 until stop roller 41 engages cavity 39. On release of the knob, springs 15 restore slide 13 to the Fig. 1 position. Similar actions occur on rotation of the knob in the reverse direction. The invention is applicable to record-player switches.
