Abstract: 1,186,735. Automatic control systems for arc welding. AIR REDUCTION CO. Inc. June 22, 1967 [June 30, 1966], No.28916/67. Heading G3R. A control system for arc welding equipment using a non-consumable electrode provides an unvarying control signal to the arc length control equipment so long as a predetermined relationship is maintained between arc voltage and at least one other arc parameter, the control signal being obtained from simultaneous and continuous input signals. In the D. C. system shown, the arc length is made independent of changes in arc current by feeding to the automatic voltage control device 64, which controls the position of electrode 52 through a conventional adjusting means 56, signals representative of arc voltage and arc current which are opposed to one another and which provide a substantially constant resultant input to the device 64 over a desired operating range of arc currents. The Specification gives typical values of the resistor R and current ratio k of saturable inductors 58, 60 suitable to provide the required compensation of the two signals over the desired range, operation of the system for changes in arc current and/or arc voltage being discussed, Fig. 1 (not shown). The operation of the current signalproducing circuit comprising members 58, 60, 70, 74 is also described. In another arrangement, Fig. 3 (not shown), the current signal-producing circuit comprises a resistor (R) connected in the electrode-workpiece circuit and supplying an inverting amplifier (80) whose output, together with the arc voltage signal, is supplied to the automatic voltage control device. The invention may be applied to an A. C. welding system and to systems wherein the device for adjusting the arc length is of the automatic current control type, e.g. when the arc length varies more rapidly with changing arc current than with changing arc voltage. Compensation for parameters other than arc current may be achieved by providing for the arc length adjusting device additional control signals representative of these parameters.

Title: An improved electron discharge device
IPC: H01J21/36
Filed: 1954-10-08
Abstract: 758,234. Thermionic-cathode tubes. MINNEAPOLIS-HONEYWELL REGULATOR CO. Oct. 8, 1954 [Oct. 21, 1953], No. 29055/54. Class 39 (1). An electron discharge tube has two or more ceramic envelope parts, one of these parts having integral therewith two parallel ribs which locate the control grid and at least one other electrode. Fig. 1 shows two ceramic parts 10, 15 which fit together in a stepped joint 13, 14, 17, sealed by a metallizing technique. Integral with the base part 10 are the two parallel ribs 11, 12. The grid 23 consists of a parallel wire structure stretched across the ribs between two L-shaped springs 30, 31 ; these are clamped between the two ceramic envelope parts, and constructed so that they are deformed beyond the elastic limit, thus imparting a predetermined tension to the grid wires. The grid terminal pin 42 is brazed into a metallized hole 43 in the ceramic base, the metallizing being continued up the side of the rib 12 so as to provide ample surface contact with spring 31. The cathode 22 is supported from a pin 35 which slides through a sleeve 36 brazed into the base 10; during assembly, a jig spaces the cathode correctly from the plane defined by the top of the ribs 11, 12, i.e. the plane of the grid. The cathode is of the impregnated type, a porous nickel base being impregnated with a barium-strontium salt, dried, and impregnated again with a soluble carbonate; washing, heating, and activating completes its preparation. Alternatively, a single impregnating step may be used, in which the barium-strontium salt decomposes directly to the oxide; suitable salts are the acetate, formate, butyrate, propionate, or higher compounds. The anode 24 is secured in the upper ceramic part 15 via a crimped sleeve 26; the device is evacuated through the anode. A finned heat-dissipating cap 45 also forms the anode connection.

Abstract: 716,543. Valve amplifying circuits. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. Sept. 7, 1951 [Nov. 29, 1950], No. 29292/50. Class 40 (6) Frequency-conscious feedback is used to extend the response of an amplifier to frequencies at which it would otherwise be falling. As applied to an amplifier, Fig. 2, comprising a first stage 1 resistance-capacity coupled to a cathode-follower 7, loss of gain at the higher frequencies caused by stray capacitance Cl in shunt to the load resistance R1 is compensated by feedback introduced by a capacitor C2 interconnecting the cathode circuits. As shown, negative feedback is applied to the stage 1 by means of a resistance RF between anode and grid of the valve. Another embodiment, Fig. 3, comprises a four stage amplifier in which negative feedback is applied over the first three stages V1-3 by means of a resistance RF interconnecting the cathode circuits of the first and third valves ; a capacitor CF in shunt with the resistance RF extends the highfrequency response. The overall response is extended by means of a capacitor Cx between the cathodes of the first and final stages.

Title: Improvements in engine starting mechanism
Filed: 1933-10-23
Abstract: 432,710. Turning gear. ECLIPSE MACHINE CO., Elmira, New York, U.S.A. Oct. 23, 1933, No. 29308. Convention date, Oct. 24, 1932. [Class 7 (v)] [See also Group XXXV] In a control system for electric starters, the starter is operated by movement of the engine load clutch from the disengaged position towards engagement and remains so operative, as long as the clutch is so released, until the engine begins to run under its own power. An electromagnetic switch 8 in the circuit of the starting motor is controlled by a manual switch 15 also controlling the ignition circuit, and by a switch 16 which is closed by movement of the clutch pedal 3 from the disengaged position. The switch 16 is actuated by an arm 34 pivoted at 35 and serving also to move the starter pinion 37 into engagement with the engine gear 38. The arm 34 is biassed by a spring 20 to the off' position and is connected to a sleeve 22 through which passes a rod 19 connected to the clutch pedals. The sleeve is latched to the rod 19 by a spring-pressed plunger 25 therein which is connected by a Bowden wire 27 to a diaphragm 29 subject to pressure in the engine intake manifold and which co-operates with a notch 26 in the rod 19. Depression of the clutch pedal causes engagement of the latch and subsequent release of the pedal results in closure of the switch 16 thereby energizing the starter motor 11. When the engine starts, suction in the intake manifold releases the latch and the switch 16 opens and de-energizes the starter motor. A positive stop is provided so that the clutch does not engage fully until the engine has started and the latch 25 is released. The notch 26 in the rod 19 may be undercut or shaped so that release either takes place as soon as the engine starts, or is deferred until the clutch pedal is depressed slightly to relieve the pressure of the clutch spring 4. In a modification of this latter arrangement, the clutch may be power-controlled by suction in the engine intake manifold under the control of the accelerator pedal. The arrangement is such that the clutch is engaged when the engine is at rest, depression of the accelerator pedal and closure of the ignition switch 15 causing cranking. When the accelerator pedal is released, a valve 47 is operated to permit suction in the intake manifold to open the clutch by acting on a piston 43. Thereafter, depression and release of the accelerator pedal cause engagement and disengagement of the clutch. A check valve 51 controlled by a wedging needle 52 is provided in the connection to the intake manifold to delay closure of the clutch until the engine has come completely to rest after a stall.

Filed: 1930-09-30
Abstract: 361,053. force-feed lubricating. CHALMERS, R. A. and TECALEMIT, Ltd., Great West Road, Brentford, Middlesex. Sept. 30, 1930, No. 29339. [Class 12 (iii).] Apparatus for lubricating axles, rollers, pins, or the like such as the pins 50 of a chain conveyer 2 comprises a grease gun 8 on a bar 10 pivoted at 23, 24 to links 13, 14 which are journalled at 17, 18 to a base-plate 1. A trolley 28 is guided on rails 3, 4 for movement parallel to the conveyer chain 2 and has a trunnion 26 slidable in a guide 27 on the bar 10, a lug 47 for guiding the piston 46 of the grease gun 8, and axles 31, 32 to which are pivoted claws 33, 34. The claws 33, 34 are connected by toggle links 37, 40, the inner ends of which are pivoted to a crosshead 38 slidably guided on a rod 39 on the trolley 28. The grease gun 8 is supplied from a fixed container 5 having a branch 52 connected by a pin 53 to the gun 8. If the toggle links 37, 40 are in line the claws 33, 34 are closed and engage a pin 50 of the moving chain 2 causing the links 13, 14 to swing and the gun 8 to move circularly towards the pin 50. The nipple 48 of the gun engages the nipple 49 of the pin 50 and a charge of lubricant is delivered to the pin during movement of the trolley 28 to the left, Fig. 5. The claws 33, 34 then open due to a pin 68 on the crosshead or an extension of one of the toggle links engaging a fixed stop 59 and the apparatus under the action of a spring 20 returns to the initial position shown. The claws then close ready to engage the next pin by engagement of the toggles with another stop which may be adjustable. In the construction shown only every third pin 50 is lubricated. This is provided by star-wheels 56, 57 on a slidable and rotatable spindle 55. The wheel 56 has six radial arms which lie in the path of the pins 50 so that engagement of a pin and an arm rotates the spindle 55 one-sixth of a revolution. The star-wheel 57 has only two radial arms each of which is arranged to engage the pin 68 and straighten the toggle links once for each revolution of the spindle 55. The wheels 56, 57 are moved out of the path of the pins 50, 68 respectively to put the apparatus out of operation by manipulation of a screw 54 on a bar 60 having an upturned end 61 engaging the spindle 55. In a modification the claws and the associated parts are omitted and the apparatus is operated upon engagement of the pins 50 with a projection on a disc fixed to a spindle slidable with the trunnion 26 which is made hollow. The spindle has an arm which at the end of the working stroke engages a stop to rotate the spindle and disengage the projection and pin 50, and upon the return stroke the arm engages another stop to reset the projection in line for contact with the succeeding pin 50. In all constructions a stop 78 limits the return movement of the apparatus.

Abstract: 1438391 Tabulation printing CASIO COMPUTER CO Ltd 20 June 1973 [22 June 1972] 29344/73 Heading G4H A control device for tabulation printing comprises synchronously circulating registers 13, 14 which respectively store tab positions 10, &c. Fig. 3A, and the position of a print head 12, and a circulating register 15 which stores the number of characters to be printed in their correct positions between two selected tab positions (Fig. 3D). As described, the number "145" is to be printed between tab positions 10 and 20 with digit "5" in position 19. The tab positions (Fig. 3A) are entered in register 13 as follows: signal 52 from a keyboard 10 steps register 14 and print head 12 (signals 53a, 53b) through 10 positions signal S1 then enables gate 16 so that the bit circulating in register 14 is entered in position 10 of register 13. Tab positions 20, &c. are entered in register 13 in the same way, and 14 and 12 are stepped back to their initial positions by a signal S4. Next, tab position 20 is entered in register 15: head 12 and register 14 are stepped to position 10, when the outputs from 13, 14 are both "I" and enable gate 21. A flip-flop 22 is set, and its output delayed by 1 bit time at 23 then fed to gate 24. When the head reaches position 20, the output from 13 provides the second input to gate 24 whose output (together with a "head stopped" signal S6) enables gate 25 to enter a bit in position 20 of register 15. The number to be printed ("145") is entered (signal S7) from 10 and stored in a buffer 11, while a signal S11 is fed to gate 43 to establish a circulation path for register 15 so that 3 bits (corresponding to the 3 digits 1, 4, 5) are entered to the left of the tab position 20 bit in 15. A signal S8 is then sent to a control circuit 34, whereupon a signal I sets flip-flop 35 to produce signals S3a, S3b again. When the bit in 14 coincides with the first bit in 15, gate 37 is enabled, flip-flop 35 is reset and the head stops in the first printing position. A signal II then opens gate 33 and the character "1" is printed. A signal III shifts the head and the register 14 to the right, and a signal IV enables gate 38 since the "1" bits in 13, 14 do not coincide; S9 causes II, III and IV to be generated twice more, and "4" and "5" are printed. The last signal IV causes gate 39 to be enabled since the "1" bits in 13, 14 coincide at tab position 20, and a "print end" signal S10 is produced. Gate 29 is closed and gate 25 is opened so that the next tab set position 30 can be stored in register 15 ready for the next printing operation. Data may be input from a calculator rather than from a keyboard, and register 14 may be a counter. Provision may be made for moving the print medium rather than the print head.
