Title: Infinitely variable overdrive transmission mechnism
IPC: F16H37/08
Filed: 1972-03-08
Abstract: 1347931 Steplessly variable overdrive transmission FORD MOTOR CO Ltd 8 March 1972 [26 April 1971] 10772/72 Heading F2D A multiple ratio transmission, Fig. 1, comprises a frictional overdrive unit 60, an auxiliary gear unit 28 and an underdrive unit of two simple planetary units 24, 26 driven by an input shaft 10 through a torque converter 16. The underdrive unit is driven from the turbine shaft 22 through clutches 56, 58 and by selective engagement of these and brakes 50, 52 and an overrunning brake 46 gives low, intermediate and direct drive ratios. The turbine shaft is also connected to the carrier 62 of balls 64 and when a brake 72 is applied to the outer races 66 the inner races 68 overdrive the ring gear 74 of the auxiliary unit 28. During overdrive the clutch 58 is released and 56 is engaged and the sun 78 is braked at 80 so that the sun 34 of the unit 24 is driven above engine speed to give an overall overdrive ratio. The frictional overdrive unit 60 can be adjusted to give an overall speed ratio from near unity upwards to a set limit thus allowing ratio adjustment without hunting between direct and overdrive ratios. In a modified arrangement, Fig. 3, the carrier 62<SP>1</SP> of the overdrive unit 60<SP>1</SP> is driven by a direct mechanical drive from the input shaft 10 while the underdrive unit is again driven by the turbine shaft 22<SP>1</SP>.

Title: Liquid straining apparatus
IPC: B01D33/073
Filed: 1971-04-22
Abstract: 1357902 Liquid straining apparatus GLENFIELD & KENNEDY Ltd 21 April 1972 [22 April 1971] 10773/71 Heading B1D [Also in Division G3]  A filter apparatus comprising a continuously moving screen, e.g. in the form of a rotary drum, disc or a moving band, includes means for cleaning the screen, driving means to move the screen so that each portion of the screen is first brought into a liquid filtering position and then into a cleaning position, and manometer means which is coupled to the driving means to control the rate of movement of the screen in response to the -difference in hydrostatic head across the screen. Fig. 1 shows a rotary drum 1 driven by motor-3 the periphery of which is formed of screens, cleaning means 2 and a pair of capacitance electrodes 4 and 5 forming the manometer means, these electrodes being situated either side of a wall 7 separating liquid to be strained from liquid already strained. The electrodes which dip into the liquid are connected to a comparator 8 (Fig. 2) which generates a difference signal which depends on the pressure difference between the electrodes. This difference signal is passed to a process controller 9 which compares the difference signal with a control signal which it itself produces and which corresponds with the desired pressure difference across the screen, The controller then generates an output signal dependant on the difference between the control signal and difference signal and this is fed to servo-motor 10 controlling the operation of variable speed motor 3. A feed-back connection is provided from the motor 3 to the servo-motor 10 to stop the servo-motor when the speed of the straining screen attains a value maintaining the required pressure difference. A remote control unit 11 containing an amplifier 12 conected to the output of comparator 8 provides a difference head indicator 13 and an audible alarm unit 14.

Abstract: 389,287. Pressure-gauge for logs. STAR, R., 236, Pearl Street, Brooklyn, New York, U.S.A. April 15, 1932, No. 10857. Convention date, Oct. 9, 1931. [Class 106 (ii).] A ship's log of the Pitot-tube type actuates a speed indicator by means of a U-tube liquidpressure gauge having a floating piston in one limb to operate through a lever and flexible connection to the indicator, the other limb being subjected to the normal pressure of the water of flotation, a vent for trapped air being provided ; the liquid level gauge being journalled to keep the limbs vertical. The Pitot tube 3 is connected by a flexible pipe 6, 7 to the actuating gauge chamber 8 in which a piston 20 floats on mercury and has a stem 21 passing freely through a passage 22 into a lower chamber 19 and engaging a lever pivoted therein. The mercury fills the lower chamber and continues into a vertical pipe 11 up which is led a flexible member 13, attached to the free end of the lever and passing up to a speed indicator 14. The gauge chambers are swung by means of a bar 27 and the pipe 11 on journal pins 28, 30, the pin 30 being on an adjustable clamp 33 on the pipe 11, to maintain the U- tube chambers vertical when the ship rolls, a short tubular sleeve 35 of resilient rubber and tubular guide block 40 carrying guide pulleys 36, 37, Fig. 4, for the flexible member ensuring proper movement. The surface of the mercury in the pipe 11 is exposed to the pressure of water of flotation through a pipe 10 open to the orifice 2 surrounding the Pitot tube and a vent pipe 17 for voiding trapped air extends above water level.

Abstract: 1,172,001. Punching; stamping. W. BURROWS. 2 Feb., 1968 [9 March, 1967], No. 11039/67. Headings B3Q and B3W. An hydraulic tool, e.g. for punching or deforming eyelets, comprises a punch 1 detachably secured to the end of a piston-rod 2 extending through a die 3, a piston 4 on the rod and slidable in a cylinder housing 5 and a handoperable lever 6 coupled with a fluid-pressure pump 9 such that operation of the lever creates fluid pressure that displaces the piston to draw the punch towards the die. Upon operation of the lever 6, pressure fluid is pumped via a oneway ball valve 12 to the left end (as viewed in the Figure) of the piston, whereby the piston is urged rightwardly against the action of a compression spring 16. With each release stroke of the lever 6 fluid enters the pump 9 from the right end of the piston by way of a one-way ball valve 18. After the operation the piston is returned to the left end of the cylinder by opening a needle-valve (21) (Fig. 3, not shown), in a passage (20) interconnecting opposite ends of the cylinder, whereby under the action of spring 16 fluid is forced from the left end to the right end of the cylinder. In a modification (Fig. 4, not shown), the right-hand end of the cylinder housing is sealed with an expansible bellows (27). The external left-hand end of the cylinder housing has a stepped formation 19, whereby dies of different sizes can be fitted, corresponding to the size of the punch selected.

Title: Improvements in and relating to photographic processes
IPC: G03F7/04
Filed: 1942-08-15
Abstract: 559,394. Coloured photographic images. BOWEN, E. WINDSOR-, and GOWER, C. H. R. Aug. 15, 1942, No. 11460. [Class 98 (ii)] In a process wherein a dye or pigment image is produced on a support of aluminium or aluminium alloy having an anodised surface by photographically forming thereon resist areas and colouring the unprotected areas, the anodised surface is coated, before applying the lightsensitive colloid layer which is used in forming the resist, with an organic colloid inert to light which protects the anodised surface from the light-sensitizing agents in the superimposed layer. The colloid used for the layers may be gelatin, albumen, or gum arabic, and the coating solution is generally made weaker in colloid for the non-sensitive layer than for the light-sensitive layer. Bubbles in the non-sensitive layer are avoided by applying it in two stages, the second being wiped over the first after a short-interval to remove any bubbles which have formed therein. The light sensitive layer may be sensitized with bichromate, e.g. by adding ammonium bichromate and ammonia to an aqueous gelatin coating solution, or with ferric chloride; and the areas of the anodised surface laid bare during development of the layer are coloured, as with dyes. The anodised surface may then be sealed by treatment with a nickel salt followed by treatment in water at about boiling point, the hot water treatment serving also to remove the resist coating. If the anodised surface is dyed before applying the colloid coatings, a result in different colours is produced when the non-resist areas are subsequently dyed.
