Title: A telephone system with satellite exchanges or similar electric systems
IPC: H04Q3/58
Filed: 1954-04-27
Abstract: 757,051. Automatic exchange systems. LICENTIA PATENT-VERWALTUNGS-GES. April 27, 1954 [April 27, 1953], No. 12121/54. Class 40 (4). In a satellite exchange, having a common calling relay for all subscribers connected thereto, this relay is connected in common over associated rectifiers to the diagonals of a number of bridge circuits each having a subscriber's loop connected in one arm. By this method the effect of variations in insulation resistance of the loops can be minimized. As shown, subscribers T1 . . . Tn are connectible by a relay switch to the exchange line La, Lb. The calling circuit consists of a bridge comprising ratio arms composed of the resistances M and B (the latter being in fact a relay coil) and bridge arms comprising respectively the subscribers' loops T 1 . . . Tn and a set of resistances W1 . . . Wn in series with the relay D. As is seen each of the resistances is connected to its corresponding loop circuit, the point of connection being connected via rectifiers G1 . . . Gn to the common calling relay An. The resistances are arranged so that the bridge is balanced under almost the worst permissible insulation conditions for the line loops. Under better conditions the bridge is unbalanced in such a direction as to back-bias the rectifiers so that An does not operate. Under slightly worst conditions the rectifiers although slightly forward biased have still a high resistance and An fails to operate. When, however, a calling loop is completed the unbalance is sufficient to put one of the rectifiers in low-resistance condition and An operates. The latter connects low resistance earth through relay D to the wire Lb to effect switching operations at the main exchange. Relay D operates in this circuit and disconnects the normally operated relay A (not shown) from the wire La. A in falling back connects up the wire La to an impulsing circuit (not shown) for the relay switch. The temporary disconnection in the wire La serves as a signal to the main exchange to send im pulses over La to step the relay switch to find the calling line.

Abstract: 448,735. Diving - chambers ; raising sunken objects. ROMANO, E. J., 1102, East Denny Way, Seattle, Washington, U.S.A. April 24, 1935, No. 12298. [Class 68 (ii)] A submarine vessel, such as a closed diving-chamber for use in salvage operations, has one or more fluidactuated arms with gripping- members controlled from inside the chamber. Fig. 2 shows a pear-shaped chamber 14 normally suspended by a cable 16. It has lights 21, and cables 20 attached to a toothed ring 101, and gripping members 76 are on arms 23, 24 on pivot shafts 26. The chamber 14 may be rotated in the toothed ring 101 by a pinion 101a moved by a ratchet lever inside the chamber 14. Long-arms.-Fig. 8 shows the fore-arm and gripping devices, and Fig. 9 the upper arm of the parts 23, 24 shown in Fig. 2. The upper arm is pivoted on a shaft 26, round which is fitted a sleeve or shaft 29 ; these shafts, together with bevel-gears 50, 51 raise and lower the upper arm in the shoulder bearing 28, and similar bevel-gears 44, 45 move the fore-arm 23. The jaws 76 are moved about their pivots 77 by levers 79, anti-friction rollers 82, and a wedge 84 thrust out by a piston 87 in a pressure cylinder 92, to which liquid is supplied by a hose 93. The piston is retracted by a spring 88. The jaws 76 may be fitted with right-angled. depending fingers. To enable the fore-arm to be rotated, the part 42 may be fitted on a sleeve rotatable on the upper arm by means of gearing operated by a sleeve fitted between the shaft 26 and the sleeve 29. Liquid is supplied to the hose 93 and cylinder 92 from a reservoir to which highpressure air is supplied from a compressed-air flask. A hand-operated relief valve is fitted. Each shaft 26 is operated by a ratchet lever 52, Fig. 6, with a reversing-pawl 53 controlled by a bent spring 57. A pedal-operated pawl 60 serves as a setting-device. The shaft 29, Fig. 9, is moved by a power cylinder supplied with high-pressure liquid by a hand pump.

Title: Improvements in and connected with automatic machine tools
IPC: B23B7/12
Filed: 1918-07-29
Abstract: 138,134. Adams Pressure Tool Co., F. E., and Adams, F. E. July 29, 1918. Lathes.-In a lathe or other machine tool having control mechanism to start and stop the various parts of the machine and control the various adjustments and settings. the mechanism comprises a series of rods 23, Fig. 3, engaging with plates 13 perforated according to the controls it is desired to actuate, the rods 23 controlling the actuation of bars 25 connected by wires 30, levers, &c. to the clutches or controls of the machine. When the desired movement is nearly completed, the moving part may operate a tappet which, through a wire 30<a> and lever 70, may release an engaging pawl 71 of a one-revolution clutch, which operates through a cam 67, lever 65, and pawl 17 to revolve the square carrier 15 and bring the next perforated plate 13 into position to engage the rods 23. Such rods as are lifted disengage their bars 25 from cross-rods 26 on a frame 27, which is given a reciprocating motion through connecting-rods 69, so that the remain ing rods operate thin wires 30 and corresponding controls. In the example described, the changespeed gear 44, 45 for the latter spindle 2 is operated by the rods 31 actuated through levers 32 having at their opposite ends catches 34 controlled by the wires 30, so that the particular catch it is desired to operate is lowered to engage a striking- slide 35 operated by a connecting-rod 40 and crank 39 driven through a clutch controlled by another wire 30. The high-speed traversing-motions 41, 42 are similarly operated, and the low-speed cutting-traverse is operated through a shaft 7 engaging a nut 8 and driven through worm gearing 81, which is disengaged by trip mechanism when d'esired. When it is desired to stop the traverse of the saddle 5, a stop thereon engages adjustable stops 80 on the grooved drum 9, which slides longitudinally and first disengages the high-speed traverse through a control wire operating the control lever 70 and bringing into action the next plate 13 as explained. The cross-slide 6 has its movements similarly controlled. The tools 87 are carried in a revolving turret mounted in a casing 85 and rotated through a shaft 90, gearing 89, shaft 48, and selector mechanism 110, controlled by wires 30, to bring the desired tool into operating position.

Title: Improvements to magnet-eddy current-type devices for use in controlling vehicle drive means
IPC: F16H61/02
Filed: 1965-03-23
Abstract: 1,105,782. Change-speed gear control. REGIE NATIONALE DES USINES RENAULT. 23 March, 1965 [27 March, 1964], No. 12334/65. Heading F2D. Automatic shifts in a stepped transmission 30 of a motor vehicle in response to vehicle speed and engine accelerator depression, with synchronization by engine speed control, are controlled by a device wherein rotation, at a speed proportional to vehicle speed, of a permanent magnet 7 in a coaxial cup 12 on a shaft 13 generates eddy currents in the cup which apply a torque thereto to turn the shaft 13 against a spiral spring 14 to successively engage arms 15 with respective contacts 16 to initiate ratio changes, the magnet 7 being axially movable on a ball spline relative to the cup 12 by the engine accelerator pedal linkage acting at F to reduce the eddy current strength as the pedal is depressed. When an arm 15 engages its contact 16, a magnet associated therewith tends to retain the arm, in opposition to spring 14, so that downshifts will occur at lower speeds than the corresponding upshifts. Each arm 15 remains on its contact 16 while higher gears are engaged. For synchronizing shifts by controlling engine speed during shifts, vehicle and engine speeds are compared by a pair of cups 19, 21 secured on a common shaft 20 biased to a neutral position by a spiral spring 26, a permanent magnet 6 being rotated in the cup 19 at a speed proportional to vehicle speed, and a permanent magnet 22 being rotated in the opposite sense at a speed proportional to engine speed. The axial position of the ball-splined magnet 22 is set in accordance with the gear ratio to be engaged in the transmission 30. During shifts, with coincidental clutch actuation by means not described, this device acts to synchronize the new ratio. If the engine runs too fast, the torque on cup 21 predominates, and an arm 27 on shaft 20 is moved away from a fixed contact 28 to reduce engine speed, while if the engine speed is too low, the torque on cup 19 predominates, causing the engine to be speeded up. Clutch control may be as described in Specification 1,105,781, and automatic double-declutching by unspecified means may be provided. In a modification, the cups 12, 21 may be axially movable instead of the magnets 7, 22.
