Title: Improvements in and relating to control valves
Inventor: HODGSON ROBERT FRASER
IPC: F15B11/05
Filed: 1969-11-26
Abstract: 1293550 Valves COMMERCIAL SHEARING & STAMPING CO 26 Nov 1969 [4 Aug 1969] 57871/69 Heading F2V A valve of the kind in which movements of a spool 12 selectively connect the ends of double acting motor (not shown) via chambers 15, 16 with either an inlet 100, feeding chambers 17, 18, or an exhaust 65, 73, connected to chambers 13, 14, is characterised by the provision of a spool 50 which is positioned by the pressure differential between chamber 52, connected to inlet 100, and a chamber X which is fed with fluid at outlet pressure. Spool 50 thus effects a variable by-pass flow from inlet 100 to exhaust via chambers 44, 14 and 73, and thereby maintains a constant flow rate to the motor under all loading conditions. Spool 12 is provided with ball check valves 24, 25 which control the flow to chamber X via channels 21, 21a, 49 and 56. The Specification describes in detail the operation of the valve in controlling a pair of hydraulic motors.

Title: New diphosphonic acids, derivatives thereof and detergent compositions containing them
IPC: C07F9/38
Filed: 1966-12-28
Abstract: 1,140,980. Hydroxymethylene diphosphonic acid and salts thereof. PROCTER & GAMBLE CO. 28 Dec., 1966 [28 Dec., 1965], No. 57932/66. Heading C2C. [Also in Divisions C1 and C5] The invention comprises diphosphonic compounds of the general formula in which each of the radicals G which may be the same or different is hydrogen or a cation giving a water-soluble salt. They may be obtained by reacting phosgene with an alkali metal dialkyl phosphite in which the alkyl groups have 1 to 6 carbon atoms at 0 to 35 C., water-washing the reaction product and subjecting the water-washed product to hydrolysis or pyrolysis. The cation G may be an alkali metal, NH 4 , substituted ammonium e.g. mono- or di-ethanol ammonium. In carrying out the reaction the phosgene is generally dissolved in an organic solvent free of active hydrogen e.g. toluene, benzene, xylene or hexane and added to the alkali metal dialkyl phosphite or the phosgene may be bubbled into a solution of the alkali metal dialkyl phosphite in the solvent. In an example phosgene is added dropwise to sodium diisopropyl phosphite at 0 to 10 C. and the resulting sodium methane phosphate diphosphonate R 2 O 3 POC(Na)(PO 3 R 2 ) 2 , where R is isopropyl is recovered and then treated under reflux with an excess of concentrated aqueous HC1 and the product converted to the aniline salt HO.CH(P0 3 H 2 An) 2  which is then treated with NaOH solution at pH 7.5 to form disodium methane hydroxy diphosphonate. The products are useful as builder components in detergent compositions and for sequestering polyvalent metal ions in aqueous solution.

Abstract: 1293574 Semi-conductor devices ASSOCIATED ELECTRICAL INDUSTRIES Ltd 1 Dec 1970 [1 Dec 1969] 58526/69 Heading H1K [Also in Division C7] A semi-conductor microwave diode of planar form comprises a wafer 2 of N-type germanium, a coating 1 of silicon dioxide containing an aperture overlaying which are successively deposited layers of aluminium 4, titanium 5 (e.g. by evaporation) and gold 7 (by electroplating). The configuration of the gold layer may be such as to provide an electrode or a beam lead. The structure may be treated to cause diffusion of aluminium from the layer 4 into the germanium to form a P-type region. In alternative embodiments the aluminium layer may be omitted, or a metal other than gold may be used for the layer 7, and the titanium layer be deleted, the completed device being of the metal-to-semiconductor junction type. A plurality of devices may be produced on a single wafer which is subsequently cut up to form single devices.

Title: Calendar timepiece
IPC: G04B27/02
Filed: 1972-12-21
Abstract: 1376696 Calendar timepieces DAINI SEIKOSHA KK 21 Dec 1972 [28 Dec 1971] 59083/72 Heading G3T A stem 16 has three axial positions, viz. (i) an inner, winding, position Fig. 1 in which a clutch wheel 10, which is slidably mounted on and rotatable by the stem, engages a winding pinion 19; (ii) a middle calendar-correcting, position Fig. 2 (not shown) in which rotation of wheel 10 rotates, via a setting wheel 12, an intermediate wheel 13 and a gear 7, either date dial 15 or day wheel 8; (iii) an outer, hand-setting, position Fig. 3 (not shown) in which wheel 10 engages wheel 12 which engages a minute wheel 11, the arrangement being such that, to avoid unintentional rotation of the minute wheel during the movement of the stem, the wheels 10, 12 are disengaged before wheel 12 engages wheel 11, wheels 10 and 12 being subsequently re-engaged. Axial movement of stem 16 rotates a setting lever 2 having a dowel 2d, which positions a spring 17, and projections 2e, 2f which respectively engage a clutch lever 18 in positions (ii) and (iii) of the stem. Lever 18 is in engagement with clutch wheel 10 and is biased counter-clockwise by spring 17. Lever 2 has an aperture 2a which is engaged by a pin 1a on a setting wheel lever 1, on a resilient arm 1e of which are mounted wheels 12 and 13. As the stem is pulled out from position (ii) to position (iii), firstly projection 2e disengages from lever 18 which is urged by spring 17 to disengage wheel 10 from wheel 12; secondly spring 17, urged by dowel 2d, engages a projection 1g of lever 1 to bring wheel 12 into engagement with wheel 11, and finally projection 2f engages lever 18 to bring wheel 10 back into engagement with wheel 12. The gear 7 of the calendar correcting mechanism is mounted on one end of a swing lever 14, the other end of which frictionally engages the shaft of wheel 13, and can move along the length of an aperture 1d in lever 1. Clockwise rotation of stem 16 causes wheel 6 of gear 7 to engage a wheel 9 which corrects the day wheel 8. Upon counter-clockwise rotation of the stem, wheel 6 engages date dial 15 which is thus corrected.

Abstract: 1449208 Vibrators T S WADENSTEN 27 Dec 1973 [30 April 1973] 59823/73 Heading F2X An air-actuated, turbine-type vibrator comprises a rotor 34, the periphery of which is formed with small transverse serrations 36, e.g. gear teeth or saw teeth, mounted on a fixed shaft 23 via a ball bearing 32 and eccentrically balanced by heavy members 38, e.g. dowels or rods, mounted to one side of the rotor 34. These members 38 may be of steel, sintered heavy metal or lead and be mounted as by a press fit or threaded retention into holes in the rotor 34 which may be a die casting of zinc or aluminium. Alternatively, plastics may be used for both the rotor 34 and its housing 10. The housing 10 is formed with legs 12, 14 for mounting on a device to be vibrated and includes a rotor chamber 16 closed at one end by an integral wall 26 and at the other end by a removable cover 20 to which the shaft 23 is secured. The distal end of the shaft 23 is threaded at 24 to receive a nut 25 on assembly of the vibrator. An air inlet 44 and an air outlet 43 are formed in the housing 10, the diameter of the inlet 44 being 30-55% that of the outlet 43 and being arranged to direct the incoming pressurized air tangentially against the teeth 36 on the rotor 34. The tooth profile is of such small size that the driven rotor under normal operating conditions provides a noise level below 85 db. (Hertz). Preferably this noise level is at or below 72 db. which is much below the accepted tolerance level.

Abstract: Movable members 9 to 11 carrying knives 6 to 8 are positioned at selected positions on a support by a bar 16 to which the members are coupled by a pin 29, carried on each member, and which engages in one of a number of holes 21 equi-spaced along the bar. The bar is reciprocated, by motor 36, so that the members may be moved, in either direction, by successive increments equal to the hole pitch. The members are moved in this manner until they each reach the nearest and most expedient hole to the new position. The bar is then moved one more pitch and as each member is determined to be at its new position its pin is withdrawn from the hole and it is clamped to the support. Mounted on the bar opposite each hole is a switch 22 arranged for operation by the pin and connected to a central micro-processor which continuously monitors and controls movement of the knife supports. <IMAGE>
