Title: Improvements in or relating to bucket excavators
IPC: E02F3/348
Filed: 1959-07-16
Abstract: 900,697. Shovelling machines. LANDSVERK A.B. July 16, 1959 [Aug. 21, 1958], No. 24449/59. Class 68 (1). An excavating and loading machine particularly for use in tunnels and like confined spaces, and comprising a vertically swingable load boom and a bucket arm movably supported by the boom, is characterized by the upper part of the boom which carries the bucket arm being swingable relative to the lower part and by the swinging part of the boom and the bucket arm being operated by independent driving means. This enables the dumping position of the bucket to be higher than is the case with an integral boom, and a larger vehicle 15 than is usual may be used. The conventional wheeled or tracked vehicle 1, with turntable 2, carries a boom 3 which is pivoted at 4 and is adjusted by an axially adjustable tie-bar 19. The bucket arm 9 is racked to engage a pinion 8a driven reversibly on the shaft 8 by a chain 16. Pivoted on the shaft 8 is the upper part 17 of the boom, this part including a guide 14 for the sliding of the arm 9. A winch 11 has a cable 12 which passes over an idler sheave, or sheaves, 21 on a stationary structure 20, and over an idler, or idlers, 18 on the part 17 of the boom, to be attached at 10a to the bucket 10. The part 17 occupies the position shown in Fig. 4 when the bucket is gathering a load but swings over into the position shown in Fig. 3 when the bucket is positioned for dumping. In a modification, an idler pinion is interposed between the rack 9a and the pinion 8 so that the bucket arm is still further raised above the vehicle 15; and in another modification this effect is increased by driving the rack-engaging pinion from the shaft 8 by a chain and sprocket.

Title: Improvements in and relating to gramophones
IPC: G11B17/00
Filed: 1924-10-17
Abstract: 242,058. British Thomson-Houston Co., Ltd., Young, A. P., and Salisbury, A. G. Oct. 17, 1924. Driving.-In gramophones having the driving spring wound by an electromotor which is switched off automatically when the spring is sufficiently wound, a cut-out responsive to the increased current taken by the motor as the winding resistance increases operates to open the motor circuit. The motor switch may be connected with the brake lever. As shown, movement of the brake lever to stop the turntable swings a pivoted arm 6 from position A to position B thereby closing the circuit of the motor 3 which also includes a cut-out coil 10 and contacts 11 bridged by a part carried by a lever 13 movable on pivot 14. The motor is thereby driven until at a predetermined resistance of the gramophone spring the current in the circuit is sufficient to lift the lever 13, thus separating the contacts 11 to stop the motor and permitting a pivoted hook 15 to engage and support the lever 13. When the brake lever is moved to start the turntable the lever 6 is moved to the position A and a projection 11 thereon disengages the hook 15 from lever 13. A spring 17 on the boss of the lever 6 bears on the lever 13 during the initial movement of the lever 6 to close the circuit and prevent lifting of the lever 13 by the cut-out when a sudden rush of current at starting is set up.

Title: Improvements in or relating to electric arc welding systems
IPC: B23K9/073
Filed: 1920-08-27
Abstract: 159,488. Wilson Welder & Metals Co., Inc., (Assignees of Churchward, A.). Feb. 18, 1920, [Convention date]. Regulation, automatic systems and apparatus for.-In electric welding, especially with a metallic electrode, large and slow variations in the current are rectified by a step-by-step resistance 7, controlled by a solenoid in shunt across the arc, while small and rapid variations in the current are rectified by a carbon-pile resistance 5, controlled by a solenoid in series with the arc, both resistances being in series with the arc, between the electrode 11 and the work 12. The carbon resistance 5 is acted on by a lever 14. A spring 18 acts on the lever to compress the resistance, while the core 15<a> of a series solenoid 3 reduces the pressure of the lever on the resistance. The switch-lever 8 of the resistance 7 is pivoted at 9, and is acted on by a spring 21 which tends to cut out the resistances, while the core 22 of a shunt solenoid 23 tends to increase the resistance against the action of the spring 21. In order to prevent excessive resistance when the electrode is in contact with the work, the first step 20 of the resistance 7 is of high resistance. The shunt circuit of the solenoid 23 is controlled by a switch 25 on the handle of the electrode 11. The movements of the solenoid cores are damped by dash-pots 16, 24.

Title: Pulse Correcting Circuits.
Inventor: FRITSCHI WALTER WILLIAM
IPC: H03K5/13
Filed: 1967-05-31
Abstract: 1,193,111. Pulse repeating circuits; transistor pulse circuits. WESTERN ELECTRIC CO. Inc. 31 May, 1967 [8 June, 1966], No. 25084/67. Headings H3T and H4K. In a pulse correcting circuit (for D.C. pulses) having two timing circuits which are triggered simultaneously at the start of a pulse to be repeated, one timing circuit times out first and opens a gate through which the remainder of the pulse passes (if it has not already ceased) and initiates an output commencing when the other timing circuit times out. The initial delay in opening the gate eliminates retriggering of the timing circuits by contact bounce or other noise during this period. The circuit shown is for repeating dial pulses. Each of the gating circuits shown incorporates a transistor and gives a positive potential output when the sum of the potentials on all inputs is below or equal to earth potential. For each dial pulse, a contact A2 closes supplying an earth pulse to a gate TCS through a diode D1 The output of this gate goes positive simultaneously triggering two monostable circuits TC and NTC, which for periods determined by respective capacitors C8 and C9 raise their " 0" outputs from earth to positive potential. A gate PR connected to the "0" output of the monostable circuit NTC, which is the one with the shortest time constant, and to the "1" output of the monostable circuit TC, has a third input connected to the (earth) pulse input by a wire 119. If the received earth pulse continues after the time out of the monostable circuit NTC all three inputs of the gate PR are earthed. A positive potential appears at its output and charges a capacitor C2. This capacitor holds the output of a gate TO at earth potential for a predetermined period. When the monostable circuit TC times out both inputs of a gate PCA are at zero giving a positive potential output at this gate. This releases a relay PC repeating the pulse over an output loop TR. While the monostable circuit TC is triggered a feed back through gates LU and N blocks the TCS to prevent re-operation by a subsequent pulse, a capacitor C4 introducing a slight delay to allow full operation by the first pulse. When the capacitor C2 has been discharged the relay PC is allowed to re-operate unless the dial pulse continues. If the pulse continues a gate LU1 supplies the positive potential to the gate TO.
