Title: Improvements in or relating to devices for transmitting motion
IPC: F15B15/06
Filed: 1962-07-02
Abstract: 1,012,051. Toothed gearing. UNITED SHOE MACHINERY CORPORATION. July 2, 1962 [July 3, 1961], No. 25212/62. Heading F2Q. [Also in Division F1] In a mechanism wherein a low-speed hightorque output shaft 26, Fig. 1, is rotated by fluid power means in response to the continuous or pulsed rotation of a high-speed low torque input shaft 40 driven by a motor (not shown), the shaft 40 comprises a rotary valve which through a port 53, Fig. 2, distributes pressure fluid successively to fixed radial cylinders 59<SP>1</SP> whose pistons, in the form of single balls 60, act on a surrounding toothed flexible sleeve 22 secured to the shaft 26 and deflect the sleeve into an elliptical or other shape to mesh with fixed teeth in a tubular housing 20 at two or more spaced regions. The two sets of teeth differ by a number equal to or a multiple of the number of meshing regions so that rotation of the valve 40 effects a circumferential translatory movement of the meshing regions to cause a slow rotation of the sleeve 22 and shaft 26 in the manner of an epicyclic gear as in Specification 790,171. As shown the port 53, which is supplied with pressure fluid from an inlet 50 through an axial bore 48, is diametral so that diametrically opposed balls 60, acting through a race 61, deflect the sleeve 22 to an elliptical shape. The other cylinders 59<SP>1</SP> are interconnected through a recessed passage 55 in the valve 40 communicating with a low-pressure line 57. In a modification the valve 40 is formed so that at any moment some (e.g. two) of the cylinders 59<SP>1</SP> are connected to high pressure, some to intermediate pressure and some to low pressure. The valve 40 may be designed to deflect the sleeve 22 to a non-elliptical (e.g. three-lobed) shape. The arrangement of cylinders may be modified to act on the outside of an internally-toothed sleeve co-operating with external teeth on a fixed central member. The mechanism described is irreversible, i.e. so long as the fluid pressure is maintained the shaft 26 is locked in any position to which it has been driven. If the fluid pressure is cut off the toothed gearing is disconnected and shaft 26 is free to rotate. Specifications 878,948 and 911,120 are referred to.

Title: Measurement of compressive loads
IPC: G01L1/20
Filed: 1964-06-18
Abstract: 1,064,516. Measuring force electrically. SOC FIVES LILLE-CAIL. June 18, 1964  [June 18, 1963], No. 25258/64. Heading G1N. A load cell comprises a steel ring A (Fig. 1) inside which a block B of rubber or the like is fitted, the block being thicker than the ring so that an axial force compresses it and causes it to exert a radial force on the ring, the consequential circumferential strain in the ring being measured by strain gauges fixed on its periphery. The block B may be annular Fig. 2 (not shown) and have a further steel ring (F) inside it, the block being thicker than either ring (F or A'). Retaining rings C, (or C', G, Fig. 2) prevent the rubber block from flowing on to the plane surfaces of the steel ring(s), when a force is applied. A fluid tight housing D (or D') protects the strain gauges. Two gauges are mounted circumferentially, and two compensating gauges are mounted perpendicular to them, the four being connected in a bridge. The output signal may be used to control an apparatus which weighs out materials in given proportions, or the cell may be used to monitor the tightening of nuts.

Abstract: 694,476. Pneumatic tyres. BENDIXWESTINGHOUSE AUTOMOTIVE AIR BRAKE CO. Oct. 30,1951 [Oct. 30, 1950], No. 25368/51. Addition to 694,475. Class 144 (ii). In a tyre inflation control system a source of compressed air 16 is connected via conduits 18, 22, 24, 26 to an outlet chamber 38 of a control valve 28 carried by a wheel 10, said outlet chamber 38 being in constant communication with the wheel tyre 14 and housing a spring- closed check valve 56 preventing return flow from the outlet chamber to the pressure-air conduit 26 and housing also a further spring- closed check valve 58 normally preventing communication between the outlet chamber 38 and an exhaust chamber 44, of the control valve 28, which is constantly open to atmosphere, a manually operable member 66 being carried by the valve casing 36 to provide for opening the valve 58 to reduce the tyre pressure. A 3  shown, pressure air is supplied from a source 16 via a regulating valve 20 which may be set to provide any desired pressure of air in the conduit 22 feeding the control valve outlet chamber 38 or may be set to connect conduit 22 with atmosphere. The conduit 22 connects with an annular chamber 50 in a fixed axle-housing 13 having air-tight seals 52, 54. The annular chamber 50 communicates with a duct 24 in the axle 12 and wheel 10 which in turn connects via conduit 26 with an inlet 42 of the valve 28. The check valves 56, 58 are arranged with a common control spring 64 therebetween and on their adjacent faces each has a boss 72, 74 respectively which co-operate when either valve is opened to keep the other closed. The manually operable member 66 comprises a button-headed spring-urged rod 68 which is slidable in the wall of casing 36 against its spring 70 to engage the check valve 58. In operation with the regulating valve 20 set to a desired pressure, the check valve 56 is held open by the air pressure in conduits 22, 24, 26 until the desired pressure is built up in the tyre 14. The regulator 20 is then turned to exhaust  the conduits 22-26 to relieve the pressure on the seals 52, 54. To reduce the tyre pressure, the regulator 20 is set to the desired lower pressure and the push-rod 68 operated to exhaust the tyre via chambers 38 and 44 to a  pressure below that set on the regulator.  Release of push-rod 68 closes valve 58 and  allows valve 56 to open to build up the tyre  pressure to that desired. More than one wheel such as 10 may be connected to the pressure-  air conduit 22 as by conduit 76.

Title: Improvements in or relating to processes for the preparation of products smelling ofirone, to processes for preparing 6-methyl-ª‡-ionine and 6-methyl-ª‰-ionone, and to products smelling of irone
IPC: C11B9/00
Filed: 1947-09-19
Abstract: A mixture of 6-methyl-a -ionone and 6-methyl-b -ionone is prepared by subjecting #z-methylpseudoionone to a ring closing treatment with an acidic reagent.  The preferred acidic reagents are sulphuric and phosphoric acids, which are used in diluted form, but acidic salts and organic acids may also be used.  The treatment is carried out initially at reduced temperature and then allowed to rise to room temperature.  In a modification of the invention the above mixture of the ionones can be obtained by a simple admixture of the two compounds.  The a -compound which is alleged to be new may be isolated in the pure condition by fractional crystallization of a ketone derivative or by fractional distillation.  The smell of the mixture of ionones is stated to be very near that of natural irone. The best result is obtained with 60-95 parts of a -compound and 35-5 parts of the b -compound.  In examples: (1) #z-methylpseudoionone is treated with phosphoric acid at -4 DEG  C. rising to 50-55 DEG  C., and (2) with acetic acid at -10 DEG  C. rising to 20-25 DEG  C. #z-methylpseudoinone is prepared by treating g -methyl linalool with a mixture of acetic anhydride and acetic acid, fractionation and saponification to give e -methyl-geraniol which is then treated with aluminium isopropylate in acetone.
