Abstract: 1,159,965. Riveting. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. 20 Oct., 1966 [20 Sept., 1965], No. 40086/65. Heading B3U. [Also in Divisions H1 and H2] A low-impedance connection between two terminal blocks 11, which are connected to main copper electrodes 1, 2 by way of copper bars 12, is established by forcing a rivet 15 of aluminium or copper through aligned apertures 13, 14 in expendable copper electrodes 3, 4, bolted to the main electrodes 1, 2 and deforming the ends of the rivet over the expendable electrodes so as to grip them tightly; during the riveting action the rivet 15 punctures an insulating sheet 10 of polythene which is disposed between the two sets of terminal block, electrodes, &c. Operation of a trigger circuit 26 renders a spark-gap 25 conductive, so causing a charged capacitor 24 to discharge through a solenoid 23; the consequent rise of magnetic flux induces in the adjacent alloy body 18 of a hammer 17 a current of such sense that the hammer 17 is repelled upwards. A steel protrusion 16 on hammer 17, and an aligned steel insert 21 in electrode 1, co-operate to expand the ends of the rivet 15. To break the connection, the riveted electrodes 3, 4 are removed; this, and the subsequent replacement of parts, may be effected automatically. The device may be used in parallel with the arrangement disclosed in Specification 1,094,192, which has a shorter connection time.

Abstract: 400,975. Boiler furnaces. CORBETT, L. W., 57, Lewis Road, Belmont, Massachusetts, U.S.A. March 4, 1932, No. 6579. [Class 51 (i).] Grates ; fuel, feeding.-A combustion apparatus for domestic heating purposes comprises, as shown in Fig. 1, a continuously-rotated conical grate 12 through which air passes from a chamber 66 separate from the ashpit, and means for continuously feeding fuel to the apex of the grate from a chamber 14 separate from the combustion chamber, so that a conical fuel bed, having, for example, a thickness of 3 ins. to 8 ins., is formed, which moves down the grate, from the base of which ash is continuously discharged into the ashpit. The grate is formed of interlocking sections 26 each having depending lugs engaging recesses in the section below, downwardly-directed air-channels 49 being formed between the sections. It is supported on ball bearings and slowly rotated in a stepby-step manner by an electric motor through a crank-and-ratchet gear provided with an adjustable masking device by which the rate of rotation may be varied, and which may be adjusted thermostatically or by hand. A substantially horizontal skirt 32 at the bottom of the grate controls the discharge of ash, and ribs 35 on the bottom of the combustion chamber wall co-operate with the grate to break up ash and clinker. Fig. 2 shows a modification in which the fuel is positively fed through a conduit 132 to the top of the grate 12 by a pusher 136 operated by an electric motor through an adjustable-stroke ratchet device. Ash is discharged through apertures in the bottom of a trough surrounding the lower part of the grate by scrapers attached to the latter (not shown). Air is supplied to the closed chamber below the grate through a conduit 166 surrounding the fuel-conduit 132, and passes in part through openings 170 in the upper end of the latter and also through an annular space 172 between it and the grate 12. A damper in the air supply conduit may be connected to the adjustable shield controlling the ratchet of the fuel-feeding mechanism in order to control the air and fuel supplies simultaneously.

Abstract: 976,386. Indicating the height of loose conducting material. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Nov. 8, 1962 [Nov. 9, 1961], No. 40183/61. Heading G1N. [Also in Division G3] The height of electrically conducting loose material in front of a gate 8 above a conveyer belt is measured by a rod shaped electrode 1, a current being driven from the electrode 1 to the gate 8 or bed 6 to give a signal which varies according to the amount of material 9 in front of the gate. The electrode 1 is preferably in series with an impedance which gives a voltage indication of the current. To compensate for changes in specific resistance of the material the driving voltage may be automatically adjusted to produce a constant current between two reference electrodes in the material. The output voltage may be composed with a reference voltage or used directly to control the rate of the conveyer or the rate of feeding of material thereto. The output voltage or the difference between the output voltage and the reference voltage may be amplified before being used to control the apparatus. Specifications 824,788, 867,865 and 873,899 are referred to.

Abstract: 897,194. Sorting letters; endless conveyers. TELEFUNKEN G.m.b.H. Dec. 17, 1958 [Dec. 20, 1957], No. 40748/58. Class 78 (1). Letters are diverted from a conveyer to one or more others by jets of air. In the arrangement shown in Fig. 1, letters resting on a conveyer belt 1a and prevented from falling off by side walls 4 either pass straight on a similar belt 1b or are deflected on to a similar belt 1c by a jet of air issuing from a nozzle 5. Air is supplied to the nozzle from a reservoir 8 through-a  pipe 7 provided with a magnetic valve 6. Some of the letters have been marked with code sign in ink which fluoresces when irradiated with ultra-violet light from the lamp 9. The fluorescence excites the photo-electric cell 10 the pulse of which after amplification by 11 actuates the relay 12 which opens the valve 6 for a short time to release a blast of compressed air. In a modification the scanned code signal is stored and the valve actuated by a beam barrier 23 when the edge of the letter reaches the junction of the conveyers. In the apparatus shown in Fig. 2, letters in channel a are fed to the junction by pairs of pressure rollers 13, 13<SP>1</SP> and 14, 14<SP>1</SP> which preferably are covered with soft, plastic, resilient material. Rails 15, 15<SP>1</SP> guide the letters between the rollers. A jet of air from the nozzle 5 urges a letter to be diverted against a more rapidly moving roller 16 which accelerates it so that it passes to the gripping rollers 17, 17<SP>1</SP>. If the letter is to be conveyed further, a pair of belts 18, 18<SP>1</SP> is provided. Letters on which the blast of air is not directed are guided by resilient wires or strips 19 to the channel b. The channel consists of belts 22, 22<SP>1</SP> running round pairs of end rollers 20, 20<SP>1</SP> and 21, 21<SP>1</SP>. Another channel similar to channel c may be disposed on the opposite side of the channel b and the channel b may be arranged to deliver to a similar set of 3 channels. This arrangement may be repeated indefinitely.

Title: Electrical identification system
IPC: H04Q3/00
Filed: 1958-12-19
Abstract: 902,172. Automatic exchange systems. STANDARD TELEPHONES & CABLES Ltd. Dec. 19, 1958 [Dec. 20, 1957], No. 41153/58. Class 40 (4). In a line identification system in which a plurality of line terminals are cross-connected by condensers to combinations of a plurality of identification terminals, the line terminal to be identified being energized by A.C., the identification terminals are connected to amplifierdetectors having an input impedance low compared with that of the condensers. It is stated that by this means so much power can be obtained at the identification terminal that only a single stage transistor amplifier is required for operating a relay in the amplifier-detector whilst at the same time substantially zero power is fed to the identification terminals not connected directly by a condenser to the energized line terminal. The invention is described with respect to a system having m<SP>p</SP> (=10<SP>3</SP>) line terminals and mp (=3x10) identification terminals each line terminal, which is fed with 20 kc/s. current when identification is required, being connected by a 0.02 ÁF condenser to one terminal in each of the three groups of ten. The line terminals are required to have substantially infinite impedance to earth and the identification terminals find earth through the input impedance of the amplifier detector which is of the order of 4 #. Fig. 3 illustrates a detector in which each point B corresponds to a different value digit, the digits being registered in a 2-out-of-5 code on relays such as Sar, Sbr. The incoming signal feeds a 14: 1 step-up transformer having a 1 K# shunt on its secondary side, equivalent to about 5# on the primary side. Rectifiers W operate in push-pull to feed transistors OC73, OC<SP>1</SP>73 whose emitter-collector currents operate relays Sar Sbr. The 2k# base resistors also in shunt with the secondary transformer winding reduce the input impedance to about 4#. The collectors of the transistors are fed via normally closed contacts of a relay Hr, which relay forms part of a potential divider. In the event of the earth side of the potential divider becoming disconnected Hr releases, thereby preventing the full source voltage from being applied to the transistors. Specifications 683,794 and 810,168 are referred to.

Abstract: 1,130,556. Automatic exchange systems. SIEMENS A.G. 29 Sept., 1965 [30 Sept., 1964], No. 41295/65. Heading H4K. In a T.D.M. system in which subscribers engaged in a connection over speech highway MS have their addresses circulating in a store Ua, a decoder Da being fed with the addresses to operate line gates once in each store cycle, an address generator AG produces a code indicating a group of subscribers, a comparator VGa determining which members of the group have their addresses circulating in Ua, the identity of these members being set up on bi-stable circuits K1-Km in a store Spa. Those stores K1-Km that remain undisturbed represent lines that are subject to inspection in the next store cycle to detect demands for service. The first undisturbed store of K1-Km is, therefore, used to identify a member of the group and, combined with the group address from AG, forms the full address of a subscriber which is applied to decoder Da during a first available time slot to connect the line circuit TS to a highway YM so that the state of the line can be detected by central control E. The identity of all lines in a group may be written direct into respective stores K1-Km in the same form as the identity circulates in store Ua. When a match is found with the group address the corresponding line address is erased from K1-Km. At the end of a cycle, those identities which remain indicate lines to be scanned. Each of the subscribers marked for inspection in store Spa is inspected in successive free time slots as indicated by gate Gf which opens gate Sc to decoder Da. If a line is found to require a connection it may be allotted the time slot in which it is tested.

Abstract: 414,140. Calculating apparatus ; games - scoring apparatus. PRIESTMAN, P. C., 15, Bridgwater Court, Bridgwater Road, Sudbury, Middlesex, and GRANT, P. L., 98, Boileau Road, Ealing, London. Feb. 2, 1933, Nos. 3256 and 18450. [Class 106 (i).] A stylus-operated games-scorer comprises a " tricks " totalizer and a "total" totalizer, each with its associated slidable actuators, and connecting means whereby amounts added to the "tricks" totalizer are entered into the " total " totalizer, but not vice versa. The device comprises a set of wheels 12<a>, 12<b>, ... for tricks " point and a set 30<a>, 30b, ... for total " points. Each set consists of two series of wheels, one for opponents' and the other for operator's scores. The total wheels 30<a>, .. are actuated by stylusoperated slides 35<a>, .. having teeth engaging ratchet wheels 32<a> and restored by springs 48b. The tricks wheels 12<a>, .. are actuated by similar slides 34b having hooked ends 39<b> which cause a simultaneous actuation of the corresponding total slides. When the tricks wheel 12<c> changes from 0 to 100 a lever 64, Fig. 9, moves a slide 60 to the right to expose a " vulnerable " indication in an aperture 63. The slide is locked in this position by a lever 68 but is released by a pin 71 on the highest total wheel 30<d> when this wheel is zeroized, the " vulnerable " indication then being cancelled. The declaration is indicated by stylus-set discs 75, 76 and " doubling " indications are given by a similar member 86. Transfer mechanism.-As a numeral wheel rotates anticlockwise, Fig. 3, a pin 20<a> thereon engages a projection 21 of a lever 15 pivoted at 16, rocking the lever clockwise against the action of a spring 17. The lever carries a pawl 23 which, when the lever is released from the pin 20<a>, actuates the next higher ratchet wheel. The lever also has an overthrow-preventing pawl 26. Zeroizing.-The numeral wheels rotating in a clockwise direction as viewed in Fig. 5 carry springs 55 projecting through apertures 54 in the wheel bosses. If the shaft 13 is rotated clockwise by a knob 51 a notch 53 in the shaft engages the end of the spring and resets the wheels.
