Title: Arrangement for regulating a quantity to a periodically determinable constant maximum value
IPC: B03C3/68
Filed: 1964-07-06
Abstract: 1,076,221. Automatic control of current and voltage. SIEMENS-SCHUCKERTWERKE A. G. July 6, 1964 [July 6, 1963], No. 27832/64. Heading G3R. [Also in Division H2] An electrostatic precipitator N is supplied . from a transformer 1 by way of magnetic amplifiers 5, 6 which maintain the precipitator voltage at a desired maximum value and which have biasing windings, control windings connected to a triode 3, the grid voltage of which is kept at a desired voltage by means of a capacitor 7, and further control windings connected to a triode 4 the grid voltage of which is determined by an arrangement 8 responsive to the actual operating voltage of the precipitator. The maximum desirable operating voltage varies with different operating conditions, and the precipitator is enabled to give an optimum performance by applying the actual operating voltage to the capacitor 7 by way of a switch 9 controlled by a supervisory device U. The arrangement is such that operation of the device U results in a continuous increase in the voltage on capacitor 7, and hence in the operating voltage, until an optimum value is reached, this optimum being determined by a flash-over in the load. If too many flash-overs occur, a switch 11 is actuated briefly to discharge capacitor 7 through resistor 14 whereby the desired value is correspondingly lowered. A current-dependent arrangement 2 supersedes the voltage control arrangement and effects regulation at constant current when conditions are such that operation at the desired maximum voltage would result in an overload.

Title: Labyrinth packing for rotating parts of machinery, particularly parts of steam and gas turbines
IPC: F16J15/44
Filed: 1934-10-02
Abstract: 445,036. Stuffing - box substitutes. ESCHER WYSS MASCHINENFABRIKEN AKT.-GES., Escher Wyss-Platz, Zurich, Switzerland. Oct. 2, 1934, No. 28183. Addition to 444,814. [Class 122 (v)] In shaft packing as claimed in the parent Specification in which rotating annular teeth 14 co-operate with stationary segmental carbon rings 5, the teeth are made of material having a greater coefficient of expansion than the parts of the machine between which sealing is effected. The teeth may be clamped between distance rings 15. The surface 17 of the carbon ring may be cylindrical or conical. In the latter case the radial clearance between the teeth and carbon may be varied by axial adjustment of one of these parts. When the packing warms up in use the higher expansion of the teeth causes them to cut grooves in the carbon thereby increasing the throttling effect on leakage.

These crenellations may take many forms e.g. rectangular or curved (Figs. 2 to 11, not shown). Pads EB, EB<SP>1</SP> against which the end card is pressed, may be located (Fig. 2, not shown) to bow the card to be fed in the concave direction with respect to direction CP<SP>1</SP> to aid feeding and separation. Flexible cards of greater thickness than the nominal gap i.e. the minimum distance between projections on opposite reference edges normal to those edges, may be fed by furrowing of the card, the actual minimum distance between edges being effectively greater than the nominal gap (Fig. 10, not shown).

The rod extends through the stem 6 and is pressed downwardly by means of a spring 16. If the mirror is accidentally struck the spring acts to restore the mirror to its original position, unless the part 9 is twisted through more than 45 degrees with respect to the base member, in which case the mirror will take up a different position, but can then be twisted by hand back to its normal location. In a modification the universal joint 23 may be replaced by a flexible cable. In another modification the universal joint is connected to one end of a tension spring, the other end being secured to the rod of the stem 6. In a further arrangement the ends of the spring are fixed respectively to the part 9 and the base member 5, whereby the spring resists twisting of the mirror from its normal position.
