Abstract: 811,465. Ascertaining the form of propeller blades. THE COUNCIL FOR SCIENTIFIC & INDUSTRIAL RESEARCH. Sept. 13, 1957 [June 14, 1956], No. 18483/56. Class 114. Apparatus for tracing the section of a propeller 10 comprises a mounting for the propeller which enables it to be rotated about its axis without longitudinal movement in relational to a supporting framework 11, a follower 21 to contact the propeller blade at a desired radius and constrained to be movable only in a direction parallel to the propeller axis, a slide 26 movable in a straight line in a plane normal to the axis of the propeller, means for imparting a movement to the slide linearly proportional to the angle of rotation of the propeller, and an indicating member 34 to which the movements of the follower and of the slide are both imparted. The propeller is mounted on a shaft 14 in a bearing 13, the height of which in the stand 11 is adjusted so that the follower 21 engages the propeller at the desired radial distance. The follower is connected by a rod 19 to a carriage 18 running in guides 17 parallel to the shaft 14, a rod 31 from the carriage transmitting movement thereof via a roller 32 in guides 33 to a rod 29 carrying the indicator 34. The rod 29 slides in bearings 28 carried -by an arm 27 projecting from the slide 26. The shaft 14 is rotated by hand gear (not shown) and carries a disc 15 which drives by friction a wheel 24 lying in the plane of the follower 21 at the end of a shaft 23 carrying a wheel 25 in frictional engagement with the slide 26. Hence movements of the indicator 34 are made up of transverse movements imposed by the slide 26 due to angular rotation of the propeller and longitudinal movements imposed by the carriage 18 due to movements of the follower 21 parallel to the propeller axis. The indicating member 34 is located in the object plane of an optical system which projects the image upon a screen 39.

Title: Apparatus for fatigue testing specimens or test pieces
IPC: G01N3/38
Filed: 1946-06-20
Abstract: 627,501. Fatigue testing of materials. DE HAVILLAND AIRCRAFT CO., Ltd., HADWIN, R. N., and POLLARD, J. R. June 20, 1946, No. 18634. [Class 106 (ii)] In apparatus for testing specimens for fatigue, particularly those of metal or wood, and having welded or resin bonded joints, two substantially identical specimens are mounted side by side in a single mounting and vibrated in opposite phase so that the fixing moments of the specimens are opposite in direction but equal in magnitude. The specimens are maintained in vibration by a magnetic exciter fed by an amplifier, the input to the amplifier being supplied by a pick-up device in close proximity to the specimens, and the output of the amplifier is limited to a constant amplitude independently of the amplitude of the input to the amplifier from the pick-up. As shown, the exciter 4, specimen mounting 16, and pick-up 6 are mounted on a base 7. The exciter is built up of E-shaped laminations with the centre limb closely adjacent the tips of the specimens. Two sets of I-shaped laminations are arranged one at each tip 9 of the outer limbs to attract each of the specimen tips. Two coils 10 are arranged on the centre limb, one being coupled to the amplifier output and the other to a source of direct current to polarize the exciter. The specimens 11, 12 are in the form of strips having enlarged ends to fit the clamp 16, and a magnetic tip is attached to each free end. The electrical pick-up 6, which feeds the amplifier in accordance with the vibrations of the specimens, may be a crystal, microphone, photoelectric cell, electrical strain gauge, or contact breaker, and feeds the signals to a degenerative amplifier A from where it passes through a phase corrector B, an amplitude limiter C, a filter D, a power amplifier E, a condenser F, and then to one coil 10. The amplitude limiter C is substantially as described in Specification 627,543. The output current through the coil 10 coupled to the amplifiers ensures that the specimens are vibrated at their natural frequency.

Title: Improvements in and relating to circuit arrangements for supplying d.c. networks from an a.c. source
IPC: H02M7/08
Filed: 1955-06-28
Abstract: 770,614. Converting; transformers. METROPOLITAN-VICKERS ELECTRICAL CO., Ltd. June 28, 1955 [June 28, 1954], No. 18703/55. Class 38 (2). [Also in Group XXXVII] A three-wire D.C. system, to which may be connected two traction or rolling mill motors 11, 21, is energized from an A.C. source 1 through a supply transformer, the outer lines 16, 26 being connected to the anodes and cathodes respectively of a number of pairs of electron discharge devices 13, 23, the other electrodes of each pair being connected together respectively to one of the terminals 4, 5 of the secondary winding 3 of the supply transformer, which winding has a neutral point connected to the third D.C. line. The discharge devices may be grid controlled to alter the voltage output, and they may act as inverters, thus allowing regenerative braking. The neutral point may be the star point of a polyphase winding connected as shown, or the central tapping of an interphase transformer joining a number of star-connected groups of secondary windings, Fig. 3 (not shown). Alternatively, the anodes and cathodes connected respectively to the outer D.C. lines may be divided each into two groups, the lines then being connected to the centre tappings of interphase coils connected between the pairs of groups, Fig. 4 (not shown). Fig. 5 shows the connections for supplying parallel connected pairs of traction motors 311a, 311b; 321a, 321b from a single phase source 301. Voltage from a tapping in autotransformer 309 is supplied to the primary winding 302 of a transformer having a secondary winding 303, the two ends and centre tapping of which are connected respectively to the two outer and the inner D.C. lines. The connections to the outer lines are made through eight rectifiers connected in parallel pairs such as 312a, 312b, inductances 334a, 334b ensuring current division. Wheel slip may be indicated or controlled from a current sensitive member 360. The connection to autotransformer 308 may be made by way of on-load tap-changing equipment, but more efficiently the tap-changing is done on the secondary winding of the main transformer, Fig. 7 (not shown). In a further voltagecontrolling arrangement the secondary winding is divided into three sections 503, 513, 523. Windings 503, 513 connected by the centretapped inductance 508 have equal and opposite voltages induced in them. The voltage induced in winding 523, which may be varied by taps up to a maximum of twice the voltage induced in each of the windings 503, 513 is applied across the ends of inductance 508 in one or other direction determined by change-over switch 520, Fig. 8. In a further modification of the tap-changing arrangement, finer voltage steps may be obtained by adding or subtracting voltage developed in an auxiliary transformer to or from the voltage derived from a main winding tap, Fig. 9 (not shown).

Abstract: 887,427. Labelling machines. MEYER MANUFACTURING CO., GEO. J. May 31, 1960 [July 27, 1959], No. 19206/60. Class 73 [Also in Group XXX] In a bottle labelling machine one or other of members 69, 70 (Fig. 5), are adapted to engage a projecting spot Px of a bottle A as it is moving along a conveyer 59, the members 69, 70 then moving towards each other so as to grip the spot Px and thereby turn the bottle into the desired radial position for receiving the labels. The members 69, 70, are so shaped (Fig. 15, not shown) and supported, that they move towards one another when pressed against the peripheral surface of the bottle. As shown, a picker (Fig. 11, not shown) brings body, shoulder and neck labels into engagement with respective transfer pads P1, P2, P3. The latter are suction operated by connections T, T1. The pad P3 is rigid with an arm 22 pivotally mounted on a shaft K and rockable periodically towards and away from the conveyer 59 by cam mechanism (Fig. 11, not shown). The pad P1 is carried by an arm 29 pivotally mounted on a shaft 27 carried by the arm 22. The arm 29 can be deflected clockwise relative to the arm 22 (as viewed in Fig. 1) against the action of springs 55 (Fig. 2). The pad P2 is carried by an L-shaped arm 39 which is fulcrumed at 37 to the arm 29 and is connected by an adjustable link 200 to the arm 22. An arm 22m carrying an arm 29m and mounted on a shaft K1 may carry further transfer pads, or as shown carries reaction pads Z4, Z5. Also mounted on the shaft 27, against spring loading relative to the arm 22, is a member 52 on which are pivotally mounted spring loaded bottle centering fingers 60, 61 (Fig. 5). The spot engaging members 69, 70, are similarly mounted on a corresponding member 52m carried by a shaft 27m on the arm 22m. In operation, the arms 22, 22m move towards each other as the bottle approaches them in its movement on the conveyer 59. When the spotting projection Px is opposite the jaws formed by the members 69, 70, the arms 22, 22m, also commence to move along the conveyer path. The arm 39 carries an adjustable feeler 77 which engages the bottle and tilts the pad P2, into engagement with the shoulder of the bottle. A stop member 58 carried by the member 52 is adapted to engage the conveyer 59. After the bottle has been turned by the engagement of the spot Px between the closing jaws 69, 70, the pads P 1 , P 2 , P 3 , thus finally arrive in label applying position (Fig. 9) reaction being provided by pads Z4, Z5. At this stage pressure is maintained by the arms 22, 22m engaging rolls 98, 99.

Title: Improvements in or relating to automatic control apparatus for heating and/or ventilating systems
IPC: B60H1/00
Filed: 1947-07-18
Abstract: 636,054. Fluid-pressure servomotor-control systems. CLAYTON DEWANDRE CO., Ltd., and EDGE, S. H. July 18, 1947, No. 19361. [Class 135] An automatic control apparatus for use with an air heating and/or ventilating system, comprises a device operable by air pressure to regulate means for controlling the temperature of air passing through the system. Air circulates through a heater and the interior of a vehicle if the temperature is low or the vehicle may be supplied with fresh air through the heater from the atmosphere if the temperature is too high, according to the position of a flap valve controlling communication between two inlet conduits and the heater conduit and operated by a piston supplied with compressed air through the control apparatus shown in Fig. 2. A thermostat phial placed at the entrance to the heater communicates by the capillary tube 3 with the bellows 4, the end of which presses on the end of a bellows 10 communicating with a conduit 19 leading to the flap-operating cylinder. A compressed-air inlet 13 leads to a valve 15 having an operating stem 15a and carrying a slidable sleeve 14 with a valve 16-at one end for controlling a port 17 in the end of the bellows 10. On a rise in temperature the bellows 4 expands and compresses the bellows 10 so that the valve 16, 17, closes. Further expansion moves the sleeve 14 so that the valve 15 opens and allows compressed air to flow via ports 14b and conduit 19 to the flap-operating cylinder. The air pressure also elongates the bellows 10 and slightly compresses the bellows 4 so that the valve 15 closes when sufficient operating pressure is built up. On a fall in temperature the bellows 4 contracts to open the cylinder to atmosphere via conduit 19, and ports 17 and 20, the valve 16, 17, closing again when the pressure is reduced sufficiently. In a modification the bellows are arranged with their axes parallel and are interconnected by a lever. The invention is also shown applied to the control of the flow of hot water to the heater.
