Title: The Assessment of Impurity Inclusions in a Material
Inventor: COAD ERNEST CHARLES
IPC: G01N23/203
Filed: 1966-06-03
Abstract: 1,174,565. Pulse circuits. VICKERS Ltd. 15 June, 1967 [3 June, 1966], No. 24951/66. Heading H3T. [Also in Divisions G1 and G4] In an electronic circuit for classifying pulses representative of impurity inclusions in the surface of rolled steel, various pulse selection circuits are provided. In a pulse height separator, Fig. 8 (not shown), comprising two Schmitt triggers (14, 15), two AND gates (17, 18) and an INVERTER (16), incoming 1V and 3V pulses on the same input line are separated into respective output channels. A circuit for passing only pulses less than 3À1 Ás in length, Fig. 9, comprises a 3À1 Ás delay line, AND gates 20, 21 and a bi-stable circuit 24. An initial setting pulse for bi-stable 24 is provided on line 25 so as to open AND gate 21. Subsequently, any input pulse less than 3À1 Ás is delayed by line 19 so that AND-gate 20 remains closed and bi-stable 24 cannot be switched back to its initial state. Amplifiers 22 (transistor) 23, 26 are provided. The circuit of Fig. 10 passes only pulses which arrive a certain duration after a previous pulse (which are a result of an inclusion spaced more than 80Á from a preceding inclusion). A first pulse entering this circuit is passed by AND gate 27 to output transistor amplifier 29. Also it causes the discharge of capacitor 32 through a transistor 31. The trailing edge of this first pulse causes switching of bi-stable 28 to its initial state and discharge of capacitor 32 to stop. The latter then continues to charge at the time constant of the circuit and the fourlayer diode 33 will strike at a time thereafter equal to the above-mentioned duration causing switching of bi-stable 28 and opening of gate 27 to any following pulse. However, a pulse arriving too soon causes discharge of capacitor 32 once again. A pulse standardiser, Fig. 11 (not shown), includes a PUP transistor (36), a delay line (37) determining the length of output pulses.

Abstract: 940,918. Carrying liquefied gases. CHANTIERS DE L'ATLANTIQUE PENHOET-LOIRE. July 10, 1961 [July 12, 1960], No. 24957/61. Headings B7A and B7S. [Also in Division F4] A vat 3, Figs. 1 and 2, for the storage of liquefied gas is surrounded by a wall 2 which is spaced from the vat 3 to provide a chamber 5 containing pulverulent insulating material, ramming of the latter being prevented or eliminated by the injection thereinto of an inert gas, e.g. nitrogen, for the purpose of stirring or fluidifying the material. The wall 2 forms part of a ship having a main hull 1. The nitrogen is supplied under pressure by way of a vertical pipe 8 to a manifold 7 leading to pipes 6, 6<SP>1</SP>, 6<SP>11</SP> which are disposed in the chamber 5 beneath the vat 3. Overlying the vat 3 is the deck 12 of the ship, Fig. 4, and disposed above the deck is a space 13 which contains a reserve of pulverulent insulating material and is connected to the chamber 5 by a duct 14 which is controlled by a valve 20 operable by means of a rod 21; any reduction in the volume of the insulating material in the chamber 5 due to ramming of the material can be compensated for by supplying the chamber with material from the space 13, or when the nitrogen is being injected into the chamber 5 any expansion of the volume of material in the latter can be allowed for by opening the valve 20. The insulating material may be fed to or extracted from the chamber 5 by pumping. An inspection manhole is provided in the wall 2, Fig. 3 (not shown), the manhole being closed by a plate which is welded in position. The inside of the wall 2 is covered with an insulating wall 19, the manhole being covered with a local layer of insulating material.

Class 38 (1) An interlocking switch and plug in which the plug cannot be removed when the switch is " on " and the switch cannot be closed when the plug is removed, comprises a locking member 36 having side limbs 40 which engage over a flange 35 on a skirt 27 of the plug 22 when the latter is in its socket 18 and the switch closed. The locking member 36 is rigidly connected to a bracket 37 which is pivotally connected by a link 38 to a bracket 39 on the switch contactoperating shaft 13, whereby rotation of the latter to open the switch slides the member 36 to the chain-line position in which it is clear of the flange 35. The socket 18 comprises a pair of spaced cylindrical members 24, 28 between which the plug skirt 27 and flange 35 are received. The outer member 28 has slots 29 through which the limbs 40 of the locking member 36 may extend, and tubular housings 42 accommodating spring plungers 41, Fig. 4 (not shown). On removal of the plug 22 the plungers 41 rise and come adjacent the ends of the limbs 40 so that closure of the switch is impossible until the plug is replaced and the plungers 41 are returned into their housings 42 by the plug flange 35. The socket member 28 has a flange plate 30 whereby it is attached to a switch box 10 by brackets 31. The plug 22 comprises a cover 32 connected to the skirt 27 by a ring 34.

Title: Improvements in and relating to the milling of flour
IPC: B02C7/17
Filed: 1929-08-16
Abstract: 337,496. Triggs, W. W., (Vitimin Milling Corporation). Aug. 16, 1929. Disc and like mills.-A process for the production of flour comprises grinding the whole grain in a buhr mill through which a draught of cooling air is caused to flow, passing the ground material to a bolting device, regrinding the tailings in a second buhr mill through which a current of cooling air is caused to flow and mixing the re-ground tailings with the ground products from the first mill by means of an air blast, the operations being carried out continuously and simultaneously. The grain enters the mill A through a pipe 39 and the ground products are discharged by a fan 12 into the bottom of the bucket conveyer 14b from which they are raised by the buckets and emptied into a shoot 15 for delivery to a bolt 16. The sifted material from the bolt is discharged through a pipe 20 by a screw 18 whilst the tailings fall into a hopper 21 and are delivered to a mill B through a pipe 22. The tailings ground in the mill B are discharged through the pipe 11 to a fan 12 where they are mixed with the material discharged from the mill A. A cyclone 24 is mounted on the bolt so that the air passing through the latter enters the cyclone through a pipe 25 and escapes by a vent 40, the deposited material being discharged through a pipe 26 on to the outside of the bolt. The fan 12 may discharge the air to the cyclone 24 either through conveyer 14<b>, pipe 15 and bolt 16 to pipe 25 or by a pipe 23 or by both. Air from outside the buildings is supplied to the mills by a pipe 34<a> from which branches 34 lead to the mills. Each mill is enclosed by a casing 33, Fig. 2, and a horizontal casing 35 forms a substantially airtight partition between the stones. The upper stone 28 revolves and a stationary feed hopper 37 is suspended over the centre of the stone. The upper edge of the hopper adjoins the casing 33 so that substantially the whole of the air entering at 34 passes through the hopper and leaves in a radial direction between the stones, thus carrying off the ground products through the pipes 10 or 11.

Title: Improvements relating to remote control systems for electric substations
IPC: H02J13/00
Filed: 1923-10-09
Abstract: 221,658. Metropolitan-Vickers Electrical Co., Ltd., (Westinghouse Electric & Manufacturing Co.). Oct. 9, 1923, No Patent granted (Sealing fee not paid). Selective distant control systems; tell-tale apparatus.-The apparatus units, e.g. rotary converters such as R, at a substation are controlled and send-back signals over a four-wire trunk 150- 153 by means of distributors on synchronouslyrotating shafts 58, 83. To start or stop a particular unit, the corresponding key K is operated, energizing one of two relays 10, 11 which connect positive or negative potential to a segment of the distributor 55. When the brush 50 engages this segment, a circuit is completed over the wire 150, brush 80 and corresponding contact of the distributor 199, dash-pot relay 200, polarized relay 92 and the return wire 153. These relays-energize and operate one of two relays 90, 91 which control the circuit breaker C to effect the desired operation. The dash-pot relay 200 is released at the brush 80 and restores the relays 90, 91. The change in condition of the contact breaker C connects positive or negative potential to a segment of the distributor 84, so that a polarized relay 12 at the control station becomes energized over the wires 151, 153. The relays 10, 11 are thereby released, cutting out the monitor lamps 30, 31, and the lamps 32, 33 are changed over to indicate the new condition of the circuit breaker. Since the relays 10, 11 are locked until the check signal is received, the sending operation is repeated until the desired operation is performed. The signalling operation described above also takes place when the condition of the circuit breaker C changes under automatic control. The armatures of the polarized relays 12, 92 are controlled so as to remain in the position to which they were last operated. Means are. described for maintaining the shafts 53, 83 in synchronism.
