Title: Improvements in and relating to telephone systems
IPC: H04M15/10
Filed: 1926-06-10
Abstract: 277,115. Marks, E. C. R., (American Telechronometer Co.). June 10, 1926. Metering systems. - A substation meter is operated by periodic reversals in the line current produced by compressing alternately pairs R1 R2, and R3, R4, Fig. 1, of carbon pile rheostats connected as shown in Fig. 6. Metering begins when the cut-off relay 13 pulls up in response to the insertion of the answering plug. A clock controlled cam 117, Fig. 2, controls with the aid of relays 120<1>, 121, 110, 111 a pair of electromagnets 105, 106 which operate through links to admit compressed air to one of a pair of cylinders 73, 74 and release it from the other. These cylinders are arranged to compress the resistances R1 - - R4 in pairs. The magnet operated interrupts its own circuit and prepares that. of the other. The rate at which the current reversals take place is controlled by back-stroke drive distributors 151, 152 driven by impulses from the cam controlled springs 114, 115 and arranged normally to connect up the relays 120<1>, 121 at every step. During slack times however, an arm 187 which rotates once in 24 hours energizes a relay 185 which disconnects the relays 120<1>, 121 from alternate terminals. Testing and adjusting. Measuring instruments 61, 64 are connected as shown in Fig. 6 for indicating want of balance in the rheostats. A switch 216 is provided for connecting a voltmeter 215 to individual rheostats. The pressure in the cylinders 73, 74 is indicated by gauges and may be adjusted by valves 83, 84. The degree to which the individual rheostats are compressed is varied by moving the operating shoes 79 along the rods by which they are carried. Switches- 210, 212 short circuit the contacts 176, 177 respectively on relay 185. Metering at different rates in accordance with the zone of the calling party, and with the timeof day. As shown in Fig. 4 the same clock controlled contacts 275, 276 control separate pairs of relays 260, 260<1>, &c, corresponding to the relays 120<1>, 121 through distributors 280, 282 which are arranged to deliver impulses to the several pairs at different rates. The relay 262 is operated through a further distributor 290 which halves the rate when 'the wires 298, 299 are not bridged by a clock contact such as 187, Fig. 2.

Title: Process for the treatment of pickle bath liquor
Inventor: BLACK GEORGE HENRY
IPC: C23G1/36
Filed: 1959-04-30
Abstract: <PICT:0877066/III/1> Pickle liquor is withdrawn continuously from the pickle bath and fed to an evaporator operating at reduced pressure in which a slurry of hydrated ferrous chloride crystals is formed.  This slurry is removed, the crystals separated, and the mother liquor returned to the evaporator.  The vapours from the evaporator are passed to a condenser, preferably via a separator to remove entrained liquid which is returned to the evaporator, and the condensed vapours, together with make-up hydrochloric acid, are returned to the pickle bath.  The vacuum in the evaporator may be maintained by extracting the uncondensed gases from the condenser.  In the drawing, an evaporator 10, consisting of a steam heated calandria, is fed with pickle liquor from tank 16. The slurry therein formed is passed to separator 11, and from thence to filter or centrifuge 29, the ferrous chloride crystals being withdrawn at 30 and the mother liquor being recycled to the evaporator via 31.  The vapours pass through a vapour/liquid separator 33, from which the liquid is returned to the evaporator, and the vapour enters condenser 36, from whence the liquid is returned to pickle bath 16.  A vacuum is maintained in the system by means of an air ejector 40 or other suitable device, for example a pump.

Filed: 1966-04-04
Abstract: 1,091,067. Control of A.C. motors. ZAVODY PRESNEHO STROJIRENSTVI GOTTWALDOV NARODNI PODNIK. April 4, 1966 [April 23, 1965], No. 14798/66. Heading H2J. An asynchronous motor M1, which drives the clamp of a machine tool, is de-energized when the clamping force reaches a predetermined value, a control circuit which comprises a relay B1 for disconnecting the motor being connected by way of transformer T1 in one supply conductor of the motor. The clamping operation is started by actuating a push-button to close contactor S1, the motor current rising to an nitial peak after which it is stabilized at a steady value. At time t1 the current increases slightly, a relay being timed to respond at this instant so that, at time t2, a contact 1B3 connects capacitor C1 through rectifier U1 across the whole of potentiometer R1. If the current exceeds the value I 0 , discharge tube X1 breaks down to energize relay B1 and disconnect the motor. If the current remains below the value I 0 , contact 1B4 is closed at time t3 to shortcircuit a pre-set portion of potentiometer R1 As soon as the chucks of the clamp engage the workpiece, the motor current rises to the value I 1  at time t4 and relay B1 is energized to disconnect the motor. The workpiece is released by actuating a push-button to energize contactor S2 for reverse drive, the motor being stopped when the push-button is released. Signal lamps may be provided.

Title: Improvements in automatic telephone systems
IPC: H04M3/12
Filed: 1919-06-13
Abstract: 149,816. Relay Automatic Telephone Co., and Johnson, B. B. June 13, 1919. Addition to 112,650. Automatic and semi-automatic exchange systems.-A line on becoming faulty prepares circuits so that when it is called a faulttone is given to a subscriber or a lamp-flashing signal to an operator. When a line A becomes faulty, its line relay L is energized and causes one of the switching-relays C to connect it, in known manner, to an idle junction line, the relay C locking up in a circuit 3 including the cut-off relav CO and a fault relay F. The impulse relay IR of the selected junction is energized over the faulty line, and after an interval, determined by a timing-device T, opens the circuit 3. The relay F, being slow to de-energize, locks up over a circuit 5 including the faulty line, but the cut-off relay CO is de-energized. When a line A in normal condition is called, one of the relays C is energized over the marking lead 66 and locks up over circuit 3. When the line becomes faulty, the lead 66 is extended over the front contact of relay F and the back contact of relay CO to the relay R6 (or R11) of an idle fault-indicating unit. When the faulty line is called, the relay R6 (or R11) is energized over circuit 6 (or 11) and a relay R7 is energized over circuit 7 to connect the calling-line to the fault tone circuit 8. The relay R7 locks up over a circuit 9 energizing relays F9, C09 which extend the circuit 6 to the relay R11 &c. of a second faultindicating unit. The fault tone set includes an interrupter so as to give a flashing signal to a calling operator. In a modification, the fault tone set is associated with each of the trunks to which a calling line is connected at the pre-digit stage. A switch may be provided whereby a faulty line may be connected either to the fault tone set or to a fault test disk or manual operator.

Title: Improvements relating to garment pressing machines
IPC: D06F71/34
Filed: 1932-05-27
Abstract: 396,522. Lift valves. JONES, G. E., 131, Glenarm Road, Clapton, London. May 27, 1932, No. 15059. [Class 135.] The steam valve e, h in an ironing-press is actuated by the handle q by which the head y of an ironing-press is raised and lowered. The handle, pivoted at r, carries a roller v which bears on the cam surface of a lever t acting on the end of a spring-pressed plunger i which opens the valve against its spring f. An adjustable abutment w limits the movement of the handle in one direction and a spur x on the handle limits movement in the other direction. The resistance ot the spring l which acts on the plunger is such that the press head can be lowered by the handle q without the valve being opened. When the press is closed, further downward pressure on the handle opens the valve by an amount determined by the setting of the abutment w. The valve may be opened when the press is open by a counterclock movement of the handle. The plunger i may be integral with the valve stem and the spring f which presses the valve to its seat c is then omitted.

Title: Improvements in Speed Gears particularly for use on Motor Cycles.
IPC: B62M25/00
Filed: 1916-10-24
Abstract: 110,581. Triumph Cycle Co., and Stanley, G. E. Oct. 24, 1916. Variable-speed toothed gearing -A sliding toothed wheel in a variable-speed gear for motorvehicles is formed with dogs on both sides to engage splines on the driving-shaft after the wheel has moved into mesh with the appropriate wheel on a countershaft. A wheel E on the driven shaft D, and a wheel I running loosely on the driving- shaft A are in permanent mesh with wheels F, H on the countershaft B. A wheel J sliding on the shaft A is formed on both sides with dogs or teeth so as to clutch the wheel E to the shaft for direct drive, to mesh with the wheel G for the second speed, or to clutch the wheel I to the shaft for low speed. The clutch teeth on the wheels and the splines L on the shaft A are alternately long and short to facilitate engagement. If, in changing speed, the long teeth or splines come into contact end on, the parts are so arranged that the wheels J, G will be slightly in mesh as shown, so that the teeth are rotated relatively to enable proper engagement to be effected. In a modification, the wheel I and its clutch teeth are replaced by a wheel fixed to the sliding wheel J and adapted to mesh with the wheel H or with a wheel cn a second countershaft to give a reverse drive. To facilitate the meshing of the toothed wheels, the teeth may be staggered

May 24, 1935, No. 15167. [Classes 39 (i) and 40 (v)] A multiplier comprises a source of primary electrons, two opposed plate-like secondary emitting electrodes and an output electrode, and means are provided for applying an alternating potential across the plate-like electrodes having a half-period equal to the time of flight of electrons between the two plates, and further means for applying a magnetic field having a component perpendicular to the electric field and inclined so that electrons travelling from one plate to the other move also towards the output electrode. As shown, the plates 8, 9 which are secondary emissive are connected across a parallel tuned circuit Vsin pt to the centre point of which is connected the output electrode through an output impedance and a source of positive potential. The angle of inclination of the magnetic field may be variable to vary the number of stages of amplification. The primary electrons may be photo-electrons. The Specification describes but does not claim a device in which one of the plates is not secondary emitting and has maintained upon it a steady positive potential and an alternating potential, the arrangement being such that electrons travel in curved paths, returning to the secondary emissive plate at another point, and devices having a number of coplanar secondary emissive electrodes opposite a single accelerating electrode.
