Title: Actuators for fluid-flow control valves
IPC: F16K31/04
Filed: 1963-07-01
Abstract: 991,950. Valves. EDWARD VALVES Inc. July 1, 1963 [Aug. 2, 1962], No. 26035/63. Heading F2V. [Also in Division H2] An actuator for a valve 40, Fig. 2A, includes a reversible electric motor 38, Fig. 2B, having means repeatedly reversing its direction of rotation to operate an impact mechanism connected to the valve. The valve 40 is rotatably attached to a stem 52, Fig. 2A, which is threaded into a sleeve 104, in turn screwed into a backing member 55 held in the casing 32 whereby rotation of the stem is transformed into axial displacement. The valve position is shown by a magnetically attractable element 396, Fig. 2B, slidable in a scale 388 and coacting with a magnet 368 on an extension 370 of the motor shaft. Impact mechanism.-The stem 52 extends beyond the member 55 where it rotatably supports a hammer 140 and a plate 148 keyed to the motor shaft 54, the hammer 140 cooperating with an anvil 144 fixed to the stem and having lugs 198, 199 that are arranged to be struck by hammer lugs 201, 202. Electric motor.-The stator laminations 234 are held between flanges 239, 240 of an adjustable shell 238 which latter embodies cooling passages 250. Rotor laminations 288, which are secured to an axially-movable rotor-shaft 54, carry cast rotor bars 296; the rotor laminations are larger than the stator laminations by an amount at least equal to the length of valve travel. Energization of the motor is controlled by a programmed timing mechanism not shown. The windings may be coated with polyvinyl chloride or polyethylene and the motor is immersed in coolant, e.g. the fluid controlled by the valve and led to the motor via a tube 404, Fig. 2A, which tube also acts to equalize the pressure differential generated when the valve moves from the open to the closed position. Alternatively, a pressure equalizing passage may be provided directly through the member 55. In a modification, the entire electric motor moves axially to operate the impact mechanism, the stator shell being mounted on bearings in the casing; the supply leads which are coiled to accommodate movement of the motor, are contained in a telescopic housing. The motor part of the valve casing may be enclosed in a cooling jacket. In another modification, the motor part of the casing 730, Fig. 5, surrounds a sealed container 734 for the stator; a coolant in the container circulates about the stator windings 758 from a tube 762 extending to a pressure equalization chamber 770 and terminating in a bellows 774; the chamber 770 opens into the casing 730. The rotor is axially displaceable relative to the stator.

Title: Electromechanical safety locking devices
IPC: H01H27/00
Filed: 1974-06-12
Abstract: 1478028 Releasable fastenings CONDUXWERK HERBERT A MERGES KG 12 June 1974 [13 June 1973] 26056/74 Heading E2A [Also in Division F2] An electromechanical safety locking device for an openable housing wall or door (not shown) of an electrically operated machine (not shown), having rotating parts (not shown), permits the door to be opened only after the drive motor (not shown) of the machine has been switched off and the rotating parts have come to a standstill, and further, prevents the machine being started until the door is properly closed. The locking device comprises a bolt 1 on the door and a sleeve 2 on the machine body, into which sleeve 2 the bolt 1 penetrates on closing the machine door, such movement of the bolt 1 initially lifting a spring-loaded locking rod 3, connected to pivot a bell-crank lever 12, and then additionally lifting a spring-loaded switch pin 4 connected by a bell-crank lever 11 to an on/off switch 10 of the machine, which lever 11 is initially prevented from moving to close the switch 10 by the bell-crank lever 12 which via the raised locking rod 3 blocks movement of the lever 11. On further i.e. full penetration of the bolt 1 into sleeve 2, for complete door closure, the locking rod 3 is spring-urged downward into a locking recess 14 in the bolt 1 to securely retain the bolt 1, which movement of the rod 3 raises the bell-crank lever 12 to release the bellcrank lever 11 which via the spring-loaded switch pin 4 snaps over to close the switch 10 to complete i.e. close a control circuit of the machine drive motor which can then be started. After the motor is switched off, a time relay (not shown) receives a pulse, the switching time of the relay being manually preselectable and set to a time greater than the time required for the rotating parts of the machine to stop, the arrangement being such that at the end of the relay switching time the contact of the time relay is closed to release a switch (not shown) to energise a solenoid 5 which via a pivoted lever 13 lifts the locking rod 3 free of the bolt 1 for the machine door to be opened.

Title: Improvements in the production of fertilisers
IPC: B01J2/30
Filed: 1931-09-17
Abstract: The resistance to caking of granular fertilizing-salts such as sodium, calcium, or ammonium nitrate, or superphosphate is improved by agitating with the granules a preferably small quantity of dry powdered non-caking substance, e.g. 0,5-3,0 per cent of the weight of the granules, in the absence of binding agents and for a sufficient period of time to produce a smooth coating of non-caking substance on the surface of the granules. The non-caking substance may be rock phosphate, calcium carbonate, talc, asbestos or graphite.  Coloured granules may be produced by using a coloured non-caking substance such as red iron oxide or by mixing a coloured material, e.g. ultramarine with the non-caking substance.  If the granular fertilizers contain one or more non-caking constituents the non-caking substance applied as a coating may comprise one or more of the constituents, e.g. finely powdered chalk may be used to coat granules containing ammonium nitrate and calcium carbonate.ALSO:The resistance to caking of granular fertilizers is improved by agitating with the granules a preferably small quantity of dry powdered non-caking substance, e.g. 0,5-3,0 per cent of the weight of the granules, in the absence of binding agents and for a sufficient period of time to produce a smooth coating of non-caking substance on the surface of the granules.

Title: Improvements in ball-point pens
Inventor: SEYER FRANK HENRY
IPC: B43K7/00
Filed: 1957-08-19
Abstract: 819,297. Reservoir pens. PAPER MATE MANUFACTURING CO. Aug. 19, 1957, No. 26122/57. Drawings to Specification. Class 146(3) In a ball-point writing unit, including a tubular ink reservoir having an open end and a tip holding a rotatable writing ball at the other end, the ink reservoir and the ball are made from dissimilar metallic materials, and the inside of the reservoir is coated throughout the length thereof with a third metallic material which is chemically non-reactive with the ink and prevents electrolytic action in the unit. Where the ball is of steel and the reservoir tube of brass, the coating inside the reservoir may be of nickel or chromium. The inner surface of the tip in which the ball is housed, and the outer surface of the reservoir, may also be coated with nickel or chromium. The metal coating may be applied by electrodeposition, or by a purely chemical process wherein the metal is deposited by chemical reduction from an aqueous solution. In an inkfilled writing unit, the electrical potential between the steel ball and the nickel plating is negligible and there is no danger of the formation of a skin or layer in the ink reservoir, due to electrolytic action, when the writing unit is stored for long periods. In addition, the nickel plating reduces the tendency of the ink to flow out of the open end of the reservoir tube and to creep toward such open end when the tube is stored for long periods in a horizontal or inverted position.

Title: Improvements in or relating to the directing of automobile torpedoes
IPC: F41G9/00
Filed: 1920-07-02
Abstract: 173,722. Whitehead Torpedo Works (Weymouth), Ltd., Sodeau, W. H., and Chick, T. W. July 2, 1920. Launching torpedoes.-The directing-device of a launching-tube is provided with a number of elements adjustable in accordance with a number of data, whereby the aim is corrected to allow for the angular-deflection of the torpedo during its travel due to the precession of the steering-gyroscope according to latitude. As shown, the sighting-telescope C is attached to a bar E pivoted at e to the usual sight-bar D. A slide F is adjusted in a radial groove E' in the bar E by means of a rack-gear f<1> and a knob F' according to the time of travel of the torpedo, as indicated by a range scale e<1> for a given speed. Another bar G pivoted at f to the bar E is set at an angle thereto by means of a crank G<1> set angularly by means of a knob G<2> according to latitude as indicated by a scale g<2x>, the crank-pin g<x> fitting in a block g<1x> slidable in a radial groove G<x> in the bar G. Finally, another bar H also pivoted at f and formed with a radial slot h is set at an angle to the bar G by means of a worm-gear g<3> and a knob g' according to the precessional setting of the gyroscope; if the gyroscope is set to run true at the equator, this last setting is nil, i.e. the slots h, G<x> are in radial alignment. The sight-bar D carries fixedly a pin d'x provided with a roller d<1> fitting in the slot h of the bar H. The effect of the above arrangement is to set the telescope C and bar E at an angle to the sight-bar D, which can be read off on a scale e<x>, this angle being half the angle of precession for the time of travel of the torpedo. The torpedo may itself be provided with precession correcting means as described in Specification 173,541.

Filed: 1971-04-19
Abstract: 1346193 Fluid pressure braking; hydrodynamic and friction brakes KNORR-BREMSE GmbH 19 April 1971 [9 April 1970] 26700/71 Headings F2E and F2F In a fluid pressure braking system, particularly for rail vehicles, in which wheels 2 are braked by friction members engaging the rims thereof, and by a hydrodynamic brake mounted on a shaft 1 between a given pair of wheels, a valve 16 is provided between the line supplying fluid pressure to friction brake actuators 30 and a line 23 leading to the pressure chamber 24 of the hydrodynamic brake, to control slip of the wheel. During normal running of the vehicle a second rotor 6 rotates with a first rotor 4. When a valve 14 is actuated to admit pressure into a line 13 a motor cylinder 11, causes through an H-linkage 10, friction members 9 to brake rotor 6 and the hydrodynamic brake to retard shaft 1. Pressure from line 13 is also admitted to a chamber 15 of valve 16 thereby depressing a piston 17 and seating a valve 29. Fluid then passes through tubular valve stem 25, chamber 26 and pipe 19 into the actuator 30. When the pressure in line 23 is sufficient a piston 21 connected to piston 17 causes valve stem 25 to unseat valve member 27 thereby venting actuator 30 to atmosphere through a chamber 29. With decreasing braking action of hydrodynamic brake 5 as wheels 2 are retarded there is a correspondingly increasing pressure admission to pipe 19 and braking action of the friction members of the wheel rims. To release the brakes pipe 13 is vented by means of valve 14 so that admission chamber 12 of brake cylinder 11 is also vented thereby lifting shoes 9, freeing rotor 6 and releasing actuators 30. Coolers may be provided to dissipate heat from the hydrodynamic brake 5.
