The control stick moves the control centre 11A of the propeller, this movement being mirrored by movement of a ball-joint 11 at said one end of the control stick which is pivoted centrally (Fig. 1). The transmitting member 14 consists of a bottom end 14A (Fig. 2) slidable in a top end 14B fixed to a spindle 18 which pivots in a ring 19. A casing of a potentiometer 21 is fixed to the ring 19, the spindle 18 being connected to the potentiometer. Pins 20, 20A of the ring 19 are mounted pivotally in a support 15 (Fig. 1) connected to the propeller casing 2, and pin 20 is also connected to a potentiometer 23 whose casing is fixed to the support 15. Pivoting of the control stick 10 causes movement of the control centre 11A and corresponding movement of the transmitting stick 14 which movement is sensed by the potentiometers 21, 23. In another embodiment, Fig. 3 (not shown), the top end of the top portion of the transmitting stick is clamped to the support (25) and the top portion is formed with a narrow portion (24C) which may bend. Above the narrow portion strain guages are mounted in two pairs, mutually at right angles in a plane perpendicular to the axis of the transmitting stick so as to sense bending of the stick when the control stick moves.

Title: Improvements relating to rotary box looms
IPC: D03D51/00
Filed: 1937-06-02
Abstract: 490,405. Rotary-box looms. BLACKBURN LOOM & WEAVING MACHINERY MAKING CO., Ltd., and WATSON, E. June 2, 1937, No. 15268. [Class 142 (iii)] The box is driven positively in both directions through a yielding safety device from a star wheel Q turned by rollers o<3> on a wheel o<2> driven by spur-and-bevel gearing o<1>, o, m<3>, M, m, l<1>, l, j<1> from a shaft J mounted in a bracket K on the swing rail L and a bearing d<5> in a bracket D. A bevel wheel j on the shaft extends between two bevel wheels G, G<1> slidably and loosely mounted on the tappet shaft E. By means of clutch fork levers F, F<1> operable by rods A, A<1> controlled by a dobby or card control mechanism, one or the other of the bevel wheels can be moved so that dog teeth on inner bosses thereon engage a dog clutch H rotating with the shaft E, the bevel wheel also being moved into gear with the bevel j, which is thus turned in one direction or the other. Studs or screws on the clutch levers may engage a slotted link whereby the simultaneous engagement of both bevel wheels with the dog clutch H is prevented. The bevel wheels are normally moved into inoperative position by a spring F<2>, and teeth on their outer bosses then engage dog teeth d2, d<3>, on the tappet shaft bearings d<4>. Spring-pressed balls or plungers on the bracket D engage notches in the boss of the bevel gear to prevent this and the shaft J from working out of position when the bevel wheel is out of gear with the bevel wheels G, G<1>. The loose star wheel Q has locking concave surfaces q<1>, engaging a boss o<4> on the wheel O, and arms q<3> projecting from a boss q<2> on the star wheel carry spring-pressed balls &c. q<4> engaging internal recesses S in a flange s<1> on a disc S fixed to the shuttle box shaft R, which can thereby thus be rotated. The drive yields in case the shuttle traps and also enables the box to be turned by hand in either direction. The bevel gearing from the swing rail may be replaced by a chain drive &c.

Title: Hydraulic checking and weighing gear
Inventor: EVANS GODFREY ARTHUR
IPC: G01L1/02
Filed: 1957-05-14
Abstract: 872,287. Weighing apparatus. HEENAN & FROUDE Ltd. May 12, 1958 [May 14, 1957], No. 15341/57. Class 143 [Also in Groups XIX, XXIX and XXXIV] An hydraulic checking and weighing gear comprises an hydraulic transmitter T and a receiver R each having a piston operating in a cylinder, fluid flow means connecting the respective cylinders whereby pressure generated in the transmitter is transmitted to the receiver, and pressure fluid bearings supporting the pistons for movement in their respective cylinders. The apparatus is shown diagrammatically in Fig. 1. A pump MP supplies oil to inlets H, H 1 , of the transmitter and receiver units T, R respectively. A pipe P interconnects the outlet ports N 1 , N 2  and ports S, S 1  are connected to the oil sump Weights W, W 1 , are placed on the transmitter and receiver, and when the system is balanced. these weights are in a predetermined ratio. Figs. 2 and 4 show the transmitter T. A piston E is freely slidable in the body of the unit and oil is supplied through restrictions r 1 , to pools G, thus forming upper and lower pressurised bearings, there being four such pools to each bearing. These bearings eliminate any metallic contact between the piston E and its housing. If the pressure of the oil in the pipe P is less than the pressure due to the weights W, the piston E falls and oil from the inlet H passes through a passage a 3  and ducts b 1 , b 2  to a passage J and then into the space K below the piston E. If the pressure of the oil is too great, the piston E rises and the passage J is opened to the drain connection S by way of an annular duct b 3  and a passage R. The pressure in the cylinder K thus balances the pressure due to the weights W, and this pressure is transmitted by the pipe P to the receiver R which consists of a piston of greater diameter supported by similar pressurised bearings in a closed cylinder to which the pipe P leads. Thus a larger weight W 1  is required to balance the weight W. Applications of the apparatus to the testing of weighing-apparatus, measuring the torque exerted by the carcase of a rotary dynamometer, and applying a known load to a strain gauge load cell or a hydrostatic capsule for testing are described. The apparatus may also act as a de-intensifier instead of an intensifier by making the transmitter piston of greater area than the receiving piston.

Title: Improvements relating to clarinets
Inventor: ACTON GEOFFREY ROY
IPC: G10D7/06
Filed: 1964-04-14
Abstract: 1,039,278. Clarinets. BOOSEY & HAWKES Ltd. March 31, 1965 [March 14, 1964], No. 15405/64. Heading G5J. In the usual Boehm system clarinet, pressure on any of the F, F# and E finger rings 11, 12 and 13 keeps the G valve which is coupled to them closed. Difficulties arise when playing F# because of the necessity to keep F covered in order to keep the G valve closed. The present invention removes this difficulty by providing an additional vent 24 in the F position, the valve 23 of which is opened by the release of pressure on the F# ring so that the tone is corrected although the F ring is covered to maintain the G valve closed. This is effected by making the shaft 15 hollow so that the F# ring rotates an inner shaft to control valve 23. A stop is also provided on ring 11 so that when it is pressed it rotates outer shaft 15 to close the G valve.

The apparatus may comprise a further operative combination of reels, platform, motor and cutting device so that two plies may be fed to the tyre building drum. Reel and guide arrangement.-The reels 28, 29 may be mounted on a carriage 35. The web from reel 28 is guided over rollers 31a, 31b, 31c to form a festoon 49 and over plates 34 and rollers 33, 141a, 1416-to the edge of platform 6. Platform.-Each platform 6, 7 may comprise an alternate arrangement of endless belts 14a-14d and fixed plates 15a-15d, Fig. 2. The former may be adjusted to a level lower than the latter, and the latter may be provided with air nozzles in order that the cord web may be floated on the platform. Cutting device.-A blade carriage 57, Fig. 2, is movable by motor 61 along tubes 56, 56<SP>1</SP> fastened to stands 58, the latter being displaceable in slots 54 located in portions 50, 50<SP>1</SP>. The latter may be displaced longitudinally of the platform along rods 51, 52. The blade may be double-edged, the edges being sickle-shaped, and it may be pivotally mounted on the carriage. Operation.-After insertion of carriage 35 with reels 28, 29 thereon into the apparatus, companion web 44 is separated from cord web 43 and fastened to reel 29 and cord web 43 is fed through the device to the edge of platform 6. Motor 16 is operated to move the cord web along the platform, the motor being stopped automatically when the leading edge of the web interrupts a light beam near the other edge of the platform. Motor 61 is then automatically started to move the blade carriage across the web, the web being cut so as to form a ply which is drawn off. Another operating cycle is then initiated. The length of cord web unwound from reel 28 is determined by the length of festoon 49, which is detected by means of light beams. Thus, when the festoon reaches a predetermined minimum length, the reel drive 125 is switched on, and when it reaches a predetermined maximum length, the drive is switched off.
