Title: Improvements in and relating to dimming devices for stage electric lighting regulation
IPC: F21S8/00
Filed: 1936-05-11
Abstract: 457,439. Variable resistances. SIEMENS - SCHUCKERTWERKE AKT.-GES., Siemensstadt, Berlin. May 11, 1936, No. 13344. Convention date, Aug. 27, 1935. [Class 37] In a dimming device for stage electric lighting regulation, which comprises regulating resistances arranged side by side, each having a current collector appropriate thereto carried by an adjustable member, all of which members are arranged to be coupled with driving rollers or discs driven by a common shaft or to be adjusted by hand, each regulating resistance is in the form of an arc and is mounted directly adjacent the adjusting member which is allocated thereto and to which is directly attached the current collector so that the latter during the adjustment process slides over the resistance. The potential for the lighting lamps is controlled indirectly by the resistance variation through the medium of a grid controlled thermionic valve or a direct current polarization of a choking coil. Each resistance is mounted on an arcuate support 30 concentric with the shaft 11 which supports the adjusting members, these being in the form of discs 18 carrying projecting arms 25. Each disc carries a current collector 31 and is adapted to be operated manually or driven in either clockwise or anti-clockwise direction upon the clockwise rotation of the shaft, according to the position of its arm 25 which serves as a selector member. The shaft 11 carries a gear disc 12 which drives a second similar gear 13 mounted freely on the hub of the disc 18 through gears 14, 16, whereby the gears 12, 13 rotate in opposite directions. The disc 18 is free on the shaft 11 but can be coupled to either of the geared discs 12, 13 or left free by means of the arm 25. This arm is notched at its inner end and this notch co-operates, according to the position of the arm which can rotate about its longitudinal axis, with one or other of two pins 26 carried by spring-tensioned levers 23. When the notch is brought opposite one of the pins 26, the lever 23 moves about its pivot and forces a roller 22 between a disc 12 or 13 and a projection 24 on the disc 18, whereby the disc 18 is coupled to the disc 12 or 13 and driven in the appropriate direction. When the notch is in an intermediate position, neither roller 22 is displaced to a position in which it locks the disc 18 to a driven part and the disc can then be manually adjusted by means of the arm 25. The rollers 22 are automatically moved out of locking engagement to free the disc 18 at the end of its movement, by engaging stops 35, adjustable relatively to the disc 18 in a slot 34 in the supporting frame.

Title: Improvements in or relating to devices for the cathodic protection of metal structures
IPC: C23F13/04
Filed: 1961-04-17
Abstract: 979, 509. Automatic control systems for cathodic protection. SOC.D'ETUDES CONTRE LA CORROSION. April 17, 1961 [April 15,1960], No. 13754/61. Heading G3R. In a cathodic protection system for a buried metal structure 1 in which current derived from a rectifier 3 is passed between the structure 1 and an electrode 2, a time switch 5 having contacts 13 controls the energization of the rectifier from an A.C. supply 7 for a given time interval from the moment when a voltage-responsive relay 4 gives a signal for closing the switch contacts. In operation, with the contacts 13 closed, the rectifier 3 is energized to supply the protection current and a coil 8 associated with the relay 4 and fed over a rectifier 10 is also energized whereby contacts 15 in the "make" coil circuit of the switch 5 are maintained in the open position. When the time switch de-energizes rectifier 3 and coil 8, the voltage between the structure 1 and a reference electrode 6 at first causes sufficient current to flow through the relay 4 to keep the contacts 15 open so that the switch 5 remains inoperative. As this voltage decreases a spring (not shown) overcomes the action of the relay 4 and closes the contacts 15 to start another cycle. A regulating resistance 9 is included in the circuit of the coil 4. A modified circuit including a voltmeter is described with reference to Fig. 2, (not shown).

Title: Improvements in engine plants such as power plants, machines, ships and the like for counterbalancing or reducing the vibrations occurring in their stationary parts
IPC: F16F7/116
Filed: 1929-05-03
Abstract: 334,521. Kjµr, V. A. May 3, 1929. Balancing.-The vibrations in power plants are counterbalanced by oscillating masses, set to vibrate by the engine &c. to be balanced at a frequency identical with the frequency of the vibration to be damped, the natural frequency of the balancing system being also equal or approximately equal to the frequency to be damped; the phases of the opposing forces are opposed. To balance the forces on the crossheads of internal-combustion engines a weight 5, Fig. 1, is carried by a springy steel bar 4; the weight bears on a lever 15 pivoted at 16 on an adjustable link 18. A second lever 11 is oscillated by cams 9 driven by the engine and causes the weight to vibrate. The position of the lever 15 is adjustable through the rod 17 and hand-wheel 21 to suit load conditions. The link 18 has a spring action to allow for excessive movement at starting. In another arrangement for balancing the reciprocating masses in an internal-combustion engine, the weight is supported by heavy springs and moves vertically between guides; it is caused to vibrate by cams, a spring link such as 18 transmitting the movement from a lever. Specification 9746/95 is referred to.
