Title: Improvements in or relating to carburettors for internal combustion engines
IPC: F02M1/16
Filed: 1947-08-14
Abstract: 655,426. Spray carburetters. CARBONARO, M. C. Aug. 14, 1947, No. 22646, 22647 and 22648. Convention dates, Aug. 14, 1946, Oct. 1, 1946, and July 22, 1947. Addition to 652,671. [Class 7(iii)] In a modification of the carburetter of the parent Specification, which comprises a nozzle 19a delivering emulsified fuel into a byepass 11a connected to Venturis 6a, 8a, above and below the throttle valve 7a and containing restrictions 12a, 13a, the delivery of the nozzle 19a is reduced at partthrottle operation. In Fig. 1 the orifice 13a is controlled by a needle 17a actuated by a capsule 16a subjected to the suction in a Venturi 18a coaxial with the Venturi 8a. The high suction below the throttle valve when it is closed causes the needle 17a to obstruct the orifice 13a, thus reducing the suction at the nozzle 19a and hence the delivery therefrom. The needle 17a may control the fuel jet 9a, and may be operated mechanically from the throttle valve 7a, Enrichment at starting is produced by a valve 22a actuated to obstruct the upper orifice 12a by hand or by means of a thermometric member sensitive to the temperature of the engine or of the cooling water. The valve 22a may also be actuated from the throttle valve to produce enrichment at full power. In Fig. 3 the Venturi 18c is fed by a compressor 21c and the float chamber 7c is connected through a cock 24c with a chamber 17c connected by restrictions 16c, 20c with the inlet pipe and atmosphere respectively so that a suction is produced therein. The emulsifying air for the nozzle 19c is obtained from the float chamber through a pipe 23c. The fuel jet 9c is fed through orifices 25c, 26c, a valve 27c connected to the throttle valve closing the orifice 26c to reduce the fuel supply at slow running. Temporary enrichment at starting is obtained by turning the cock 24c to disconnect the float chamber from the suction in chamber 17c. In a modification the cock 24c is omitted and the chamber 17c is connected to the throat of the Venturi 18c, enrichment at starting being obtained by obstructing the upper orifice 12c as in Fig. 1.

Title: Improvements in or relating to amplifying circuits having automatic gain control especially for picture signals in television receivers
Inventor: GODIER IVAN
IPC: H04N5/50
Filed: 1953-08-18
Abstract: 756,951. Automatic gain control. ELECTRIC & MUSICAL INDUSTRIES, Ltd. Aug. 9, 1954 [Aug. 18, 1953], No. 22709/53. Class 40 (5). In a television receiver having automatic gain control (A.G.C.) means are provided for transiently reducing the gain when the receiver is switched on. The receiver comprises a detector 4 direct-coupled to a video-frequency amplifier 6, to the anode of which the cathode of the picture-tube 12 is directly connected. Composite video and sync. signal, the latter component being positive-going, is fed via condenser 15 to the anode of a diode 16. The sync. pulse peaks are thereby clamped at approximately the cathode potential of the diode 16, and a stabilized composite signal appears across resistor 21. It is smoothed by a resistance-capacity network 22-25 to give an A.G.C. voltage on line 26 proportional to the average value of the composite signal. Such a system is liable to be overloaded if a strong signal is present when it is switched on, since an appreciable time must elapse before an A.G.C. voltage builds up across network 22-25; in the meantime the valve 6 may limit and so produce a waveform which is unsuitable for the generation of an A.G.C. voltage. Such overloading is prevented by deriving the cathode potential of the diode 16 from a condenser 20 connected to a potentiometer 19 between the screen grid of valve 6 and a point of negative potential. As described, the latter comprises the grid of line output valve 31. The screen grid of valve 6 is fed through a series resistor 28 ; upon overload its potential falls, so that a negative pulse is communicated via diode 16 to the A.G.C. line 26. The gain is thus momentarily reduced, removing the overload on valve 6 and permitting proper operation to ensue. A diode 34 ensures that the potential of the A.G.C. line 26 can never become positive.

Title: Improvements in or relating to the pulverising of coal
IPC: B02C4/02
Filed: 1932-08-13
Abstract: 407,316. Roller mills. CAREY, W. F., BRAWN, E. F., Norton Hall, The Green, Norton-on-Tees, and IMPERIAL CHEMICAL INDUSTRIES, Ltd., Millbank, London. Aug. 13, 1932, No. 22763. [Class 59.] A process for pulverizing coal to particles less than one twenty-fifth of an inch in size consists in crushing the coal in a .multi-stage roll crusher in which the individual stage reduction ratios, with the possible excepttion of the ratio for the last set of rolls, lie between 2.0 and 3.6, or in which the average stage reduction lies between these limits. As shown, coal of about “" size is passed over a magnetic pulley 9, which rejects tramp iron &c. down a shoot 10, and enters rollers A direct or after passing through a screen. It then passes through rolls B onto a screen 8 having a mesh about two or three times as wide as the gap between the preceding rolls which removes flakes to a shoot 12. After passing through rolls C, D the ground material is discharged through the bottom of the mill, preferably by a screw conveyer 7. The reduction ratio through A and B may be 3.16, C 2.0, and D 5.0. The R.P.M. assuming 10-inch rolls for A is 72.5 and the speed of the other rolls is in proportion to the reduction ratio. The critical stage reduction ratio lies between 3.1 and 3.6 according to the kind of coal used as above these limits wear of the pulverizing surfaces increases very rapidly whilst below these limits the amount of wear is nearly independent of the stage reduction. A lower limit of 2 is preferable as below this figure a large number of rolls &c. is required. The coal, distributed to the first set of rolls, leaves about 65 per cent free space in the gap so that the particles are presented singly and separately to the rolls. Each pair of rolls runs in the opposite direction at the same peripheral speed and the rolls are made, or surfaced with, nickel-chrome steel. The distance between the rolls may be adjusted by screws 14.

Title: Improvements in or relating to the treatment of hydrocarbons
IPC: C07C9/00
Filed: 1939-08-11
Abstract: 535,813. Hydrocarbons. STEVENS, A. H. (Phillips Petroleum Co.). Aug. 11, 1939, No. 23212. Drawings to Specifications. [Class 2 (iii)] In the production of saturated hydrocarbons of higher molecular weight from paraffins of lower molecular weight the paraffins are converted to olefines by de-hydrogenation; the olefines are polymerized, the polymers are separated into fractions of higher and lower molecular weight, the higher fraction being depolymerized and passed to the previous polymerization step or to a previous separating step, and the lower fraction is hydrogenated with the hydrogen produced in the dehydrogenation step. The separation of the hydrogen from the dehydrogenation may be effected before or after the polymerization. The invention is described with reference to the conversion of paraffins of 2-5 carbon atoms to a product boiling in the gasoline range. Suitable catalysts for the dehydrogenation and hydrogenation steps are gels containing chrommium oxide with the addition of other oxides, an example being chromium aluminium and magnesium oxides in the molar ratio 6 : 3 : 1. In an example the dehydrogenation of a mixture of propane and butanes is effected at 475‹ C., the products being liquefied and then passed over an acid alumina gel containing some silica at 250‹ C. ; a 5 per cent. fraction of the polymers boiling in the gasoline range is hydrogenated as described above and the remaining 15 per cent. having a higher boiling- point is de-polymerized at 380‹ C. with a silicaalumina catalyst, yielding 25 per cent. of olefines suitable for adding to the polymerization step, and 36 per cent. of hydrocarbons boiling in the gasoline range. A part of the hydrogen produced in the de-hydrogenation step may be removed from the system or additional hydrocarbon may be added at the hydrogenation stage.

Title: Circuit for impulse frequency division
Inventor: HULIK ZDENEK
IPC: H04Q1/50
Filed: 1954-08-10
Abstract: 773,214. Counting apparatus. TESLA NARODNI PODNIK. Aug. 10, 1954, No. 23238/54. Class 106 (1). [Also in Group XXXIX]  In an impulse frequency division circuit, each impulse causes the discharge of a condenser, the first discharge being fed first to an operating winding of a relay, which then locks over a second winding, and a subsequent discharge being fed either to the operating winding or to another winding in such a manner as to neutralize the flux due to the holding winding. As shown, Fig. 1, the first discharge of condenser C1 (due to operation of contact i) operates A over its left-hand winding, whereupon A locks over its right-hand winding and changeover contacts of A ensure that the next condenser discharge takes place in the opposite direction through the left-hand winding so releasing the relay by differential action. Condenser C2 ensures that the operating winding receives operating current during the transit time of the relay contacts. In a modification, Fig. 2 (not shown), the condenser is continuously charged over a resistor. In a further modification, Fig. 3 (not shown), the operation of the relay transfers the next discharge to a third winding wound in opposition to the holding winding. In a variant of this, Fig. 4, when the relay is operated over its left-hand winding by the first discharge the relay locks over its two left-hand windings in series. These are wound in opposition, but the current in the upper winding over-rides that in the lower. The second discharge not only increases the current in the lower winding, but, by lowering the potential applied to the lower end of the upper winding reduces the current therein so facilitating its release. In a scale-of-5 counter, Fig. 6, the first discharge operates A which locks, and the second operates B which also locks. The third discharge now passes through the left-hand winding of A in the opposite direction, so releasing A. The fourth discharge now operates C and the first discharge passes through the lefthand winding of B in such a direction as to release B, whereupon C releases so that the circuit is again normal. A scale-of-three counter is also described, Fig. 5 (not shown).

Abstract: 1,178,219. Laying pipes. SOC. DES GRANDS TRAVAUX DE MARSEILLE SOC. ANON. 16 May, 1968 [31 May, 1967], No. 23303/68. Heading F2P. Pipe lines being laid from a pontoon on to the sea bottom are relieved of bending moment induced by swell by the use of a pivoted laying beam 1 having a power operated clamp 8 secured to the beam by long rods 16 to the beam at 20, and also having a pair of frames 21, 22 which include adjustable sets of four rollers by which the inclination of the cable can be adjusted (Fig. 8, not shown). The lower end of the beam forms a downwardly curved ramp (Fig. 5, not shown) provided with adjustable rollers 29 and fixed ones 32a ... 32d. The weight is counterbalanced by weight 10 connected over pulley 13 to the clamp 8. The inclination of the beam is set by rod 4 and rack 7. In order to lay pipe, a new section is mounted at the top of the beam and welded or screwed to the pipe line, rollers 33, 34 being power adjusted to give alignment. Other power adjusted rollers are also provided. A pipe laying trolley 38 rides up and down the beam from top position 39 to lower position 38<SP>1</SP>. This trolley clamps the pipe, and with clamp 8 released, it is fed down the beam as the pontoon moves forward, by winch 46 through irregular amounts dictated by the swell conditions. The tension rods 16 which hold clamp 8 are provided with lostmotion slots 17 at their top ends, so that it can easily be seen when the winch cable has fully taken up the pipe tension and clamp 8 can be released. In very bad weather, the pipe line is sealed by a stopper 50, Fig. 7, to which the winch cable 45 is secured. Rollers 29 are lowered and pulley 37 is raised to guide the pipe and cable as the pipe is lowered to the bottom while the pontoon moves forward. The cable winch, once again feeds at a variable rate to accommodate swell.

Title: Telecommunication exchange
IPC: H04Q3/00
Filed: 1967-05-19
Abstract: 1,128,555. Automatic exchange systems. INTERNATIONAL STANDARD ELECTRIC CORP. 19 May, 1967 [21 May, 1966], No. 23395/67. Heading H4K. In an exchange system comprising a multistage reed relay switching network through which paths are selected by means of a route simulation network, route selection consists in sending an offering signal through the simulation network from a particular inlet (junctor) to all free outlets (subscriber lines) selecting one of the latter (calling or called), blocking all nodes in the last stage of the simulation network and then successively unblocking these nodes oneat-a-time until the offering signal reappears at the selected outlet and thereafter performing a similar blocking operation at each stage in turn until finally only one free route remains. The offering signal appears at the indicator AA on the "outlet" side of the simulation network shown in the Figure. Whenever AA is operated it seizes a common control circuit V which couples a pulse generator RZ to the particular node blocker AKAA-AKAB which is next to be used. A node blocker automatically blocks all the nodes in its associated stage and then unblocks them successively and one only at a time under the control of RZ until an offering signal reappears at AA. The blocker then "stands" on the node which has just been unblocked so that at the end of route finding the relevant cross-points in the corresponding matrix can be actuated. The network shown corresponds to a sectionalized switching network (Str1-Strn) so that before the node blockers can be brought into operation, a similarly operating section blocker AKSA must first be actuated in order to enable the nodes AV in one section only, the node blockers being common to all the sections. If the switching network comprises many stages, a free node in the centre stage of the simulation network is first chosen, after an outlet has been selected, and thereafter an indicator similar to AA is connected to this node and route finding then proceeds simultaneously in the two halves of the network (Fig. 3, not shown). This method may be extended by further subdivison of the network. Several control circuits and their associated ring counters (clocks) may be provided. If one ring counter fails its functions may be taken over by the counter associated with another control circuit. In order to increase the speed of route finding the indicator can be connected to the just selected node in each stage so that signals are not unnecessarily delayed by having to traverse selected nodes in the preceding stages (Figs. 4 and 5, not shown).
