[Class 51 (ii)] [Also in Group II] Apparatus for the continuous treatment of finely divided material comprises a container and a helical coil mounted at both ends so as to rotate therein in close proximity to the wall of the container, or the lower part of it; the direction of rotation is periodically reversed by any suitable mechanism so as to prolong the treatment; and the helix presents projecting curved or inclined surfaces in cross section to the material to facilitate slippage thereof over the coils. Fig. 1 shows an electrically-heated furnace in which the material, fed from a hopper 28, is agitated by a coil 12 of circular cross section mounted at its ends on cooled bearings 11, 24, and is discharged by a shoot 34. The coil is supported by notched plates 44 and is driven by a pinion 37 and a gear wheel 36. The section of the coil may be approximately triangular with a curved base next to the periphery and straight or curved sides. The coil may be hollow for the circulation of fluids or their injection into the chamber which may be gas tight, or may be open at the top. Figs. 4 and 5 show another form in which the coil 53 is supported by an internal coil 52 and the charging hopper is provided with a power-operated sliding gate for regulating the rate of feed. The hopper has oppositely inclined staggered walls so that the material falls in a sinuous path, and the gate may be operated pneumatically 'in step with the direction of rotation of the helix. Means are provided for withdrawing liquid products without admitting air to the chamber. Specification 540,212, [Group II], is referred to.

Title: Improvements in or relating to the reproduction on a reduced scale of the voltage of a high voltage a.c. system
IPC: G01R15/06
Filed: 1930-05-05
Abstract: 354,236. Pressure meters. REYROLLE & CO., Ltd., A., Hebburn-on- Tyne, and LEBEN, H., 8, Queen's Walk, Harrow, Middlesex. May 5, 1930, No. 13791. [Class 37.] Relates t the true reproduction, on a much reduced scale, of the high voltage of a supply system for measuring the voltage by means of low-voltage instruments by connecting one end of the primary winding C of a transformer (the other end of which is earthed) through a capacity coupling, which may be an ordinary condenser-type bushing insulator, to the line A, connecting the secondary to a tuned circuit F, E and supplying the instruments from the tuned circuit. According to the invention the instrument L is supplied with a voltage derived from (i) part of the tuned circuit D, E, F (the inductance F in the Figure) and (ii) an additional voltage derived from the whole of the tuned circuit. The resulting two voltages are vectorially added through the small transformers G, H and J, K and the resulting voltage supplied to the instrument. In a modified arrangement, the additional voltage is derived from an additional secondary on the transformer C connected in series with the secondary H or in series with the primary G. The last arrangement is described in connection with a three-phase line, Fig. 4 (not shown), in which three low tension lines are obtained reproducing in miniature the high voltage three-phase line.

Patent GB-167027-A (GB)
Title: Improvements in electric bells or similar apparatus
IPC: G10K1/064
Filed: 1920-05-20
Abstract: 167,027. Fisk, A. May 20, 1920. Electromagnetic interrupters. - Electric bells and other electromagnetic apparatus are operated by current in one direction only, an auxiliary light armature opening the circuit when current of the other direction is applied. In the example shown, a permanent magnet M carrying a light flexible extension X is arranged so that the extension X comes between the extensions F, G, of the ordinary electromagnet pole pieces. When current passes through the apparatus in a direction to cause the extension F and the extension X to attract each other, the contact Z is maintained and the bell rings. Current in the opposite direction however, causes a rapid oscillation of the armature X which has a much higher frequency than the bell armature, and the bell remains silent.
Patent GB-630385-A (GB)
Title: Improvements in or relating to locks
IPC: E05B63/18
Filed: 1947-05-27
Abstract: 630,385. Locks and latches. CHAMBERS, N. May 27, 1947, No. 14024. [Class 44] In a spring lock, that part of the follower which' is in contact with the bolt or striker when the latter is withdrawn to or near to the end of its travel, or that part of the bolt or striker with which it is then in contact, or both these parts, is or are so shaped that the radius sector from the centre of rotation of the follower to the point of contact lies on the common normal at that point, or lies within the smaller angle made by the common normal with the direction of travel of the bolt or striker. Under these conditions, the force of the spring acting on the bolt cannot rotate the follower, and the bolt will remain withdrawn until the follower is turned slightly by the handle or key. As shown in Figs. 1 and 2, a piece of metal is shaped to fit round the striker 2 of the bolt tail, and having a gap 3 into which the horn of the follower falls when the latter is near the end of its rotation. In the form shown in Fig. 3, the shape of the end of the follower is modified at 10, and a part 9 of the striker 7 is cut away.

Patent GB-923744-A (GB)
Title: Improvements in automatic defect signalling systems
IPC: G08B23/00
Filed: 1961-04-18
Abstract: 923,744. Protective arrangements. COMPAGNIE DE CONSTRUCTION DE GROS MATERIEL ELECTRO-MECANIQUE. April 18, 1961 [May 24, 1960], No. 14045/61. Class 38 (5). [Also in Group XXXVIII] In a system in which one or more of p different faults may occur, each fault, when it occurs causing an associated fault indicating line to be marked, means are provided for recording and indicating the order in which the first n faults occur. As described, the order in which the first two of p fault-indicating lines 1, 2 ... p, Fig. 1, are marked is recorded and indicated. Each fault indicating line, e.g. p, has three bi-stable storage devices Mp1, Mp2, Mp3, associated with it. These storage devices are so arranged in column as shown, that if any device, e.g. Mp1 in the first column (extreme right-hand column) is " on a  column conductor Y 1 Y 1 <SP>1</SP> is earthed, via a diode Pp1, thereby preventing any other storage device in that column being turned " on." Similarly, any device " on " in the second column prevents any other device being turned on in that column by earthing a column conductor Y 2 Y 2 1. In operation, each storage device is first reset by applying a negative pulse to every row conductor. The first fault that then occurs marks its associated line, e.g. p, which causes the third storage device Mp3 to be turned " on." This in turn applies a negative pulse via an R-C coupling to the adjacent storage device Mp2 which goes " on," and similarly this storage device turns on the first storage device Mp 1. The turning " on " of device Mp1 however turns " off " the previous device Mp2. Thus, finally the result of the first fault-indicating pulse is that storage devices Mp3 and Mp1 are both " on " and an output is taken from device Mpl to an indicator (Fig. 2, not shown). The next fault-indicating pulse that occurs attempts to cause a similar sequence of events. However, since the first column is now blocked by the earthing of column conductor Y 1 Y 1 <SP>1</SP>, the second storage device is unable to turn the first storage device " on " and so it remains on. Thus, the second fault-indicating pulse causes its associated second and third storage devices to go " on." Any subsequent fault-indicating devices are then effective only to turn on their third storage devices. Thus the circuit described indicates which faults were the first two to occur, and also any subsequent faults but not their order of occurrence. The circuit can easily be extended to identify the first n faults. The actual visual indication of a fault is effected by lamps (Fig. 2, not shown), there being one lamp for each fault-indicating line 1, 2... p, the lamps being controlled so as to flash in distinctive ways to indicate whether a fault is the first, second or subsequent fault. Specification 923,743 is referred to.

Title: Control device for gaseous fuel burning appliances
Inventor: GARNER RUSSELL FREDERICK
IPC: F23N5/10
Filed: 1956-05-07
Abstract: 798,913. Controlling burners. ROBERTSHAW-FULTON CONTROLS CO. May 7, 1956 [Aug. 8. 1955], No. 14080/56. Class 75(1) [Also in Group XXIX] A gas control device for a main and pilot burner comprises a casing 10, Fig. 1 with inlet 12 connected by passage 16 to outlet 14, a safety cut off valve 22 in the passage controlled by pilot flame failure device, and timing means 24 for actuating a timer valve 20 in the passage. A plug 30 is turned by its knob 92 to allow gas to flow via passage 36 and filter 40 to a closed pilot burner valve 192, Fig. 3. On depressing button 178, an electromagnet 152 and its housing 148 are moved downwards against spring 150 to make the magnet contact an armature 164 biased downward by spring 172 to hold the valve 22 closed, and a pin 204, Fig. 3 carried by the housing, moves on to a cam 210 on the armature stem whereby the pin opens the pilot 192. When the pilot burner lights, a thermo couple energizes the magnet which lifts the armature, on releasing the button, and allows spring 133 to open valve 22. Pin 204 remains on the cam 210 and keeps the pilot valve open. Should the pilot flame go out, the magnet releases the armature and closes valves 22, 192. A knob 100 is now depressed against leaf springs 136, 138 to move two diametrical fingers 108 out of slots 120 and on to two concentric helical cams 118 on a fixture 112 in the knob 92. The knob 100 and fingers are carried by a rod 90 which contact valve stems 74 and lifts valve 20 off its seat on the plug valve against spring 84. Knob 100 is now turned to move the fingers over the helical cams and wind up a clock movement 130 through spring 138 on rod 90 engaging spring 136 on a pinion 134. The plug 30 is now turned to full on position allowing gas to pass both timing and safety cut off valves to the burner. The clockwork returns the fingers along the cam until they re-enter their slots and close the valve 20 after a time interval determined by the rotation of knob 100. The relation between the strokes of the helical cams is such that a small torque is needed to move the fingers against friction of the cam and is independent of the axial thrust of rod 90.

Abstract: 1283665 Four phase logic system PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 11 May 1971 [13 May 1970] 14142/71 Heading H3T In the two stages I, II of a delay element comprising PET's M 1 , M 2  and M 5 , M 6  the drains of M 1 , M 5  are connected to # 1  and 93 respectively and their gates to # 2 , # 4 , the drain of M 1  is connected to M 6  gate and to C 1 , and M 2  gate receives an input; and in addition M 2  and M 6  drains are connected, such as by M 4 , M 8 , to # 3  or # 4  and # 1  or # 2  respectively, and M 2  and M 6  sources are connected such as by M 9 , M 10  to # 1  or # 2  and 93 or # 4  respectively but not during # 3+4  and # 1+2  times respectively. The improvement over the prior art is stated to be that whereas M 8  (or M 4 ) which conducted in # 3  time (Fig. 1, not shown) to negatively precharge stray C 52  and undesirably tended to partially charge C 1  due to the stray C d , thus risking M 6  being turned on subsequently by the erroneous charge on C 1 , it is now ensured that M 8  charges Cd in # 1  or # 2  time while M 1  and M 2  are still operative. Thus, C d  is charged up fully and if V i  is low then M 1 , M 2 , M 9  hold C 1  at zero potential (that of # 1  line in # 2  time), and C 1  cannot be subsequently erroneously charged by C d  because the latter is charged to the full clock source voltage. If V i  is zero, then C 1  stores the whole negative clock level as normal.
