Title: Improvements in or relating to fluid pressure control valves
IPC: F15B13/04
Filed: 1961-06-20
Abstract: 985,308. Valves. G. HECKMANN. June 20, 1961 [June 21, 1960], No. 22278/61. Heading F2V. A main spool valve 17 controlling inlet, exhaust, and work ports 26-29, is moved between opposite end positions by the controlled fluid supplied to end chambers 21, 22, the pressures in these chambers being controlled by positioning of an auxiliary piston valve 2 housing a ball valve 4, under the control of an external pilot valve which may be pneumatically, or electromagnetically operated to open and close an outlet control conduit 1 from the auxiliary piston, the arrangement being such that successive opening movements of the control valve result in alternate movements of the main valve from one end position to the other whilst successive closing movements thereof result in positioning of the auxiliary piston alternately in one or the other end position to control the main valve. Pressure fluid is supplied to the end chambers through the interior of the main valve and orifices 15, 16 therein, and the chambers are selectively placed in communication with the control conduit 1 by the auxiliary piston, opposite end chambers of which are selectively placed in communication with the pressure supply or exhaust of the main valve through passages 10, 11 by movement of the main valve. In the position shown, the external control valve is assumed closed. The right-hand end of the auxiliary piston communicates with the pressure supply and the left-hand end with exhaust. Opening of the external control valve results in the main valve moving to the right, thus reversing the connections 10, 11. Ball valve 4 moves to the right past radial ports 7. On re-closing the external control valve pressure builds up on the left of the auxiliary piston moving it to the right in preparation for a reverse movement of the main valve on the next succeeding opening of the external control valve. The main valve may be controlled directly by shut-off valves connected at 30, 31 to the end chambers. In another embodiment, a plain piston auxiliary valve is used, the ball valve 4 being replaced by two ball check valves between the end chambers of the auxiliary piston and the control conduit 1. The device may be used, e.g. in the control of a remote-operated points-adjusting apparatus such as for a travelling train in mining work.

A spinning or twisting machine has the supply of material to be processed located at a lower level than the spinning or twisting elements, the thread drawing or advancing elements being intermediately located and the spindles suspended in a substantially vertical position and inverted with respect to the conventional arrangement. In a machine for spinning cotton yarns directly from slivers, the slivers are drawn from cans A, pass through drafting apparatus B and lappet-guides G to yarn packages P on spindles H. Traveller rings are carried by reciprocating rails N. A single drafting apparatus may serve both sides of the machine, in which arrangement the two rows of spindles may be close together to provide a narrow machine. A woollen spinning machine described has condenser bobbins mounted on rotating rollers located slightly above floor level, from these material is passed through twist tubes and reciprocating balloon control rings to a ring and traveller device and the yarn package. Guards fixed along the outer edges of the ring rails protect operatives from injury from broken travellers. The Provisional Specification states that the spindles may be horizontal or arranged at some angle between horizontal and vertical. Specification 706,054 is referred to.
Patent GB-761712-A (GB)
Title: Silica-alumina compositions and process for the preparation thereof
IPC: C10G11/04
Filed: 1954-08-03
Abstract: A silica-alumina composition suitable for use in catalysis is prepared by adding an acid (e.g. sulphuric or hydrochloric) to an aqueous alkali metal silicate (sodium or potassium ortho- or meta-silicate), adding an aqueous salt containing aluminium in the cation (e.g. aluminium chloride or sulphate) to the so-formed slurry to precipitate hydrous alumina, adding an aqueous salt containing aluminium in the anion (e.g. sodium or calcium aluminate), to precipitate a further quanitity of hydrous alumina, and recovering the solid product.  By filtering the final slurry and reslurrying or removing water from the final slurry, in either case to give a total solids content by weight of 8 per cent and spray-drying, microspheres of clear, glasslike structure are obtained which may be washed and dried for use in fluidized catalytic processes.  The compositions may be used alone or in association with oxides of other elements e.g. magnesium, zirconium, titanium, thorium, chromium and/or boron.  In comparative tests, the catalyst was steamed prior to use in a cracking process by dripping water upon it while a pressure of 40 lbs. per sq. inch gauge and a temperature of 1200 DEG F. were maintained.  The following specific details are given : (a) in the initial step the concentration of acid should be sufficiently low to prevent local reaction and heat generation; 25 to 35 per cent H2SO4 is suitable, and agitation is desirable especially with concentrations greater than this: (b) whilst the acidification of silicate can be completed at as low a pH as 5, it is preferably retained above 7, e.g. 8 to 10.5 (c) the quantity of salt having aluminium in the cation should be such as to render the mixture acid and precipitate alumina, e.g. by lowering the pH to below 2: (d) in examples, the sodium aluminate solution contains also sodium hydroxide and in some, sodium carbonate; the ratio water to salt in the aqueous solution of the salt containing aluminium in the anion is preferably at least 7.5 to 1, better 15 to 1 (as Na2Al2O4): (e) the quantity of said salt to be added may be only such as to precipitate alumina in acid medium e.g. at a pH of 5 to 5.5: (f) the temperature of the reaction mixture is preferably 40 to 140 DEG F.; if precipitation is performed in the cold, it is desirable to heat to 100 to 190 DEG F. preferably 110 to 150 DEG F. before filtration: (g) the slurry is preferably dried by passing a spray in the same direction as a hot gas at 200 to 1000 DEG F. to give a particle temperature of 150 to 300 DEG F., preferably 150 - 230 DEG F.: (h) the catalysts may contain 5 to 45 per cent by weight of alumina on a dry basis, and catalysts containing 13 per cent and 20 to 40 per cent of alumina, the latter of which are particularly stable to steam, are referred to: (i) the preferred particle size is 20 to 100 microns. Examples are also given.

Filed: 1969-05-02
Abstract: 1276382 Photographic processing apparatus CORDELL ENG Inc 2 May 1969 22629/69 Heading G2A A photographic film 158 passes from a loading box 13 through the various stations of a processing and drying apparatus, and is taken up on a spool 166. The transporting means is such that the speed of the film tends to be increased as it passes through the apparatus. The film is conveyed by passing between sets of rollers 66-67, 68-69, &c., which are themselves driven from a motor 35 and sprocket 36 via a chain 37, which drives each pair of rollers through a sprocket and gear connection. To prevent looping, roller 66 is driven at the slowest speed, and roller 68 at a somewhat higher speed (by means of a slip clutch). Each pair of rollers, or selected pairs only, may be driven at a higher speed than preceding rollers, and the final pair 90, 91 is driven at the highest speed of all. The various processing baths form part of a single moulded tank. The developer bath has an upper section 31 and a lower section 53, divided by a plate 57. Developer solution is pumped into the lower section through an opening 52, and heated to a thermostatically controlled constant temperature, whence it passes through nozzles 58, 59 to the applicator chambers 64, 65. These have slots in their upper surfaces (196, 197) Fig.8 (not shown) through which the solution is expelled to impinge on the film passing just above them. Splash plates 92, 93 are provided above the film. Spent solution passes out of the bath through a pipe 94, and can be replenished with fresh solution and re-circulated. A similar arrangement is provided for the fixing bath 32 and wash bath 33. In the drier section the film passes through three chambers 147, 149, 151 receiving heated air from a blower 145. Each of these three chambers has a serrated interior face, with slits 153 through which the heated air can circulate over both sides of the film (see also Fig.4A, not shown). The loading box 13 may have different compartments to accommodate films of different widths, which are fed out through opening 163 to the processing section.
