IPC: H02P5/695
Filed: 1959-09-04
Abstract: 966,078. Automatic speed control. GENERAL PRECISION SYSTEMS Ltd. Sept. 1, 1960 [Sept. 4, 1959], No. 30349/59. Heading G3R. [Also in Division H2] A servo-system has two motors coupled through a differential gear to provide a fast and a slow drive to an output shaft in dependence on the magnitude of an input signal. As shown, a motor 11 drives a shaft 15 through a differential gear 16 in a ratio K : 1 and a motor 12 drives the shaft 15 through the gear 16 in the ratio αK : 1 where α is of the order of 100. Tachogenerators 17, 18 are driven by motors 11, 12 respectively and apply velocity feed-back to an input of cascaded amplifiers 13, 14. The velocity feed-back signals are additive and the ratio between them is determined by resistance R in the feed-back path from the generator 17 and a resistance of α times R in the feed-back path from generator 18. The motor 11 is controlled by the output of the amplifier 13 and the motor 12 by the output of the amplifier 14. For low input signals the output from the amplifier 13 is not sufficient to cause motor 11 to rotate and the shaft 15 is rotated at a low speed by motor 12. At high input signal levels the motor 11 supplements the drive from the motor 12 which tends to a maximum value. It is stated that a third motor can be employed energized by the output of a third amplifier fed from the output of the second amplifier and driving through a multiple differential.

Title: A method and apparatus for contacting a liquid and a gaseous fluid
IPC: B01D47/02
Filed: 1945-11-13
Abstract: In a multiple-column fractionating apparatus wherein each column is fed at the base with vapour and wherein the reflux liquid flows down from each contact device, e.g. a plate, to the next lower contact device in another column, clogging and backflow of liquid is eliminated by providing conduits of narrow cross-section between the vapour spaces above the connected contact devices.  Columns 11 and 12 are each provided with superposed contact devices (cross - hatched rectangles) arranged so that the contact devices of one column are vertically offset with respect to those of the other.  The inlets 3 of the contact devices in column 11 are connected to the outlets 41 of the contact devices of column 12 by siphons 7; similarly, inlets 31 are connected to outlets 4 by tubes 6 and siphons 71.  Vapour streams A1 and A2 are supplied to the bottoms of columns 11 and 12 respectively.  Narrow conduits 8 connect the vapour spaces of the columns and permit a small amount of either vapour stream to pass from one column to the other so that the pressures above those contact devices connected by tubes 6, are balanced.  An embodiment having four columns connected in <PICT:0624615/III/1> series is also described.  In the case of several columns, the vapour spaces at a given level may be connected to a common tube.

Each disc 12 is fast on a shaft 14 and its periphery is formed with grooves 11. Each disc 12 is associated with an identical disc 16 which rotates therewith and is angularly adjustable with respect thereto to adjust the width of the grooves to the diameter of the tube. Bolts 17, 18 fixed on the disc 16 extend through slots 19 in the disc 12. The bolt 17 is connected to the disc 12 by a tension spring 21 and the bolt 18 extends through the free end of an adjusting spindle 23 mounted on the disc 12. A pointer 24 carried by the bolt moves over a scale 25 mounted on the disc 16. Each pair of discs 27 is mounted rotatably on a fixed shaft 28 which is mounted in bearings 29, Fig. 4. The bearing 29 is movable along spindles 30, one of which is threaded, mounted in brackets 31. The threaded spindles 30 of each pair are connected by a chain 34 so that they are moved simultaneously to vary the depth of the grooves 11.

Abstract: 153,259. Soc. IndÚpendante de TÚlÚ- graphie sans Fil. Oct. 28, 1919, [Convention date]. Void [Published under Sect. 91 of the Act]. Electric oscillations, producing; thermionic relays.-High-frequency oscillations for wireless signalling are produced by a three-electrode valve in a circuit consisting of an inductance across the grid and the plate, and are stated to result from the capacity of the electrodes. In an example, Fig. 6, the filament current traverses part of the inductance 11 and an additional coil 14 wound with it, the battery 4 being thereby excluded from the oscillation circuit. The fixed potential between the plate and the filament is furnished by a direct-current source 8, which is connected to the plate through a choking-coil 15, and is pre- ' vented from being short circuited by means of the condenser 16. Oscillations are produced in the circuit 2, 3, 11, 12. In a modification, the positions of the connexions of the grid inductance 12 and the plate 3 with the inductance 11 are reversed, the choking-coil 15 and the condenser 16 being then omitted. The double coil 14 may be omitted, the battery 4 being connected directly to the filament 1 and a tap from one of the leads being taken to a point on the antenna inductance 11. Further inductance &c. may be added for tuning purposes, the arrangement being applied to wireless telegraphy or telephony in any known way for transmission or reception.

In a machine for making envelopes, the envelope blanks are retained in a pile in a holder which is adjustable in a straight line transversely to the direction in which the blanks are separated from the bottom of the pile, and the stops which position the pile in the holder can be pivoted about a point situated on the centre line of the holder, so that the stops move together in a direction transversely to the direetion of sheet separation. As shown in plan, the base 1 of the pile holder is secured to two transverse rails 2, 3, the rail 2 having trunnions 4, 5 resting in open bearings in brackets 6, 7 secured to the frame 8, and the rail 3 is freely supported by the frame. The trunnion 4 is screw-threaded to receive a nut 11 having a groove 13 which is engaged by a fork 14 secured to the bracket 6. Thus, when the nut 11 is rotated, the base 1 is adjusted transversely. The stops 27, 28, 29 which locate the pile of envelope blanks 30 on the base 1 are all secured to a rail 17 pivotally mounted by a control bolt 18 to the base 1. A tension spring 22 arranged between a peg 23 on the rail 2, and a peg 21 on the rail 17, urges the rail 17 clockwise about the pivot 18, this movement being limited by a stop-screw 24 on a bracket secured to the rail 3. Thus, when stop-screw 24 'is adjusted, all the stops 27, 28, 29 are adjusted transversely. The stops 27, 28 are secured to feet 31, 32 which are slotted and secured to the rail 17 by screws 35, 36, and the stops 29 have slotted feet 33 secured by screws 37 to the feet 32.

A crossbar switch has a fixed frame GK with L-shaped guide holes FS through which coupling finger KF extends. The coupling finger rests in a slot in selector bar AS and can be moved laterally with the selector bar. The contacts are closed when selected by switching bar SS which moves forward and presses the coupling finger against contact operating block BK. In the rest position, slots Aa in the selector bar and As in the switching bar are in line. In operation, selector bar AS shifts coupling finger KF laterally to take it out of alignment with slot As and move it past edge VK in the guide hole. Switching bar SS is operated to close the selected contact which moves finger KF out of slot Aa so that selector bar AS can be released. Switching bar SS is now released leaving finger KF trapped between edge VK and the solid edge of selector bar AS and the contact is kept closed. The contact is opened by re-operation of the selector bar. Contacts KA are stated to plug into a printed circuit board.
