Title: Method of conveying particulate material
IPC: B65G53/22
Filed: 1954-05-13
Abstract: 751,162. Pneumatic conveyers. POLYSIUS GES. May 13, 1954 [April 5, 1954], No. 14089/54. Class 78 (1). In apparatus for discharging finely-divided material from a container 1 and conveying it through pipes 2, 8 by compressed air admitted through a porous base 3, excess air is discharged through a pipe 6a disposed above the material and connected to the upper end of the pipe 2. The flow of air through the pipe 6a is regulated by a valve 7 which is adjusted in accordance with the readings of the pressure gauges M<SP>1</SP>, M<SP>2</SP> and M<SP>3</SP>. The pipe 2 may be connected to the base 3 and disposed below the container.

Title: Improvements relating to vacuum electric tube devices
IPC: H03B5/10
Filed: 1924-06-11
Abstract: 239,299. Robinson, E. Y., and Metropolitan-Vickers Electrical Co., Ltd. June 11, 1924. Thermionic generators. - The grid biassing-voltage of an oscillating valve is obtained by rectifying alternating current provided by a separate thermionic oscillator; and failure of the grid biassing-voltage is caused to interrupt the plate current of the main oscillator. As shown in Fig. 2, a back-coupled valve 1 supplying oscillatory current to the aerial 11 has its plate current supplied by a dynamo 4, and its filament energized from an alternator 22 through a transformer 20. The auxiliary back-coupled valve 14 has both its filament and plate circuits supplied from tho alternator 22 through the transformers 21, 25 respectively. The grid circuit of the oscillator 14 includes a condenser 18 and leak resistance 19, and the potential arising from the flow of grid current through the resistance 19 is applied to the grid of the main valve 1 across a condenser. Undesirable inter-action between the two grids may be prevented by a choke coil in the connecting lead. A relay winding' 27 is also included in the grid circuit of the auxiliary valve 14, and if this valve fails to oscillate, the relay 27 is deenergized and closes a contact in the circuit of a battery 28 and coil 29, thus opening the switch 30 in the plate circuit of the main valve and preventing overheating thereof. The switch 30 may also be arranged to be opened on failure of the generator 22. The filaments of the two valves 1, 14 may be connected in series.

Title: Improvements relating to coiler head for drawing frames
Inventor: MACKIE JOHN KAY PRINGLE
IPC: B65H54/80
Filed: 1964-04-07
Abstract: A hinged inspection hatch in the cover of a coiler-head provides access to the sliver delivery rollers and is held closed by a catch which is interlocked with mechanism for separating the rollers against spring loading so that the rollers can be moved together only when the hatch is closed and the hatch can be opened only when the rollers are separated.  Operation of the catch to open or close the hatch automatically separates e.g. by a camming action, the rollers (whereupon delivery ceases and a blockage may be safely cleared) or permits the rollers to move to their operative position in which they may be secured by the cam until the catch is released and the hatch opened.

Abstract: 1532093 Magnetoresistive heads PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 12 April 1976 [15 April 1975] 14770/76 Heading G5R A magnetic head has an elongate magnetoresistive element 1 with an easy axis of magnetization M parallel to its length, a middle contact 21 midway between end contacts 5 and 6, a strip, or a pattern of parallel strips, 11 to 15, of readily electrically conductive material on the portion 2 of element 1 between contacts 5 and 21 with the or each strip at an acute angle of 30 degrees to 60 degrees to the axis M, and a similar strip, or pattern of parallel strips 16 to 20, of readily electrically conductive material on the portion 3 of element 1 between contacts 6 and 21 with the or each latter strip at an obtuse angle to the axis M, the obtuse angle being the supplement of said acute angle. Each strip 11 to 20 forms a respective equipotential surface so that with current sources 7 and 8 connected as shown and with strips 11 to 15 at 45 degrees to axis M and strips 16 to 20 at 135 degrees to axis M, the equipotential surfaces cause the current I 1  in element half 2 to be at 135 degrees to axis M and the current I 2  in element half 3 to be at 45 degrees to axis M. A differential amplifier 9 subtracts the voltage across contacts 21 and 6 from that across contacts 21, 5.

The under surface 9 of the jewel or the base 3 of the plate recess in which the jewel is housed is slightly coned to prevent surface contact. The plate recess in which the jewel is housed is shown as having its peripheral wall cylindrical for a short length 4 corresponding with the height of the lower outer edge of the coned undersurface 9 of the jewel but thereafter is slightly flared to permit tilting of the jewel.

Title: Improvements in electric signalling systems
IPC: G01F23/44
Filed: 1938-05-20
Abstract: 515,212. Electric signalling systems. KENT, Ltd., G., and COOKE, G. P. May 20, 1938, No. 15138. [Class 40 (i)] In a device for transmitting values such as liquid levels, the movement is made to store energy in a spring which is then released suddenly to operate a magneto which transmits an impulse.. In the form shown in Fig. 1 a counterbalanced float 1 rotates a wheel 6 toothed at 7. One of these teeth engages and moves an arm 9 so rotating a shaft 10 against the action of a spring 14 which presses on a cam 13. On sufficient rotation the tooth 7 becomes disengaged from the arm 9 and the energy in the spring is released thus turning the shaft 10 rapidly and causing the magneto 11 to transmit an impulse along the wire 21. The rotation of the armature is limited to an angle under 180 degrees so that impulses may be semidirectional, but their sign will depend on the direction of rotation. In the receiving device rectifiers are arranged so that current flows through either coil 17 or coil 18 according to the size of the impulse so that an armature 19 is attracted to one side or the other. This motion is transmitted via the shaft 20 to the ratchet and pawl device 27 and 28 which operates the pointer 29. In the modification of the transmitter shown in Fig. 2, the pulley 3 is fast with the disc 32 which has a pin 33 carrying a roller 35 urged by the spring 34 against a fixed face cam 36, which is provided with equally spaced recesses. The unrecessed parts of the cam 36 hold the forward end of the pin between one of three pairs of lugs 37 on a disc 38 connected to the armature spindle 39 of the magneto. On rotation of the pulley 3 the magneto spindle rotates until the roller moves opposite a recess in the face 36 whereupon the pin is freed from the lugs 37 and springs 40, 41 bring the magneto spindle back to its normal position causing an impulse to be transmitted and the forward end of the pin 33 moves between another pair of lugs 37.
