Title: A process for avoiding inadmissible tension conditions in switched off circuit portions of alternating current electric supply systems
IPC: H02P9/10
Filed: 1925-06-09
Abstract: 235,869. Siemens - Schuckertwerke Ges. June 18, 1924, [Convention date]. Protective arrangements for wattless current compensated systems; systems depending on the use of two or more machines.-In alternating current systems to which are connected machines or apparatus for supplying wattless currents means are provided to ensure that the interruptions of the connection with the power source is accompanied by the automatic limitation of the production of wattless currents so that undeeirable rise of pressure in the disconnected circuit are prevented. Acording to Fig. 1, a resistance 7 is inserted in the field circuit of a synchronous machine 4 by a relay 6 where the switch 1 is opened to cut off the power supply. A condenser battery 11 which furnishes wattless energy compensation to circuits 3, 9 and 10, Fig. 2, is shunted by a resistance or choking coil 14 when the switch 12 opens the resulting rise of tension acting through a relay 13 which is also arranged to cancel the condenser action when the tension falls below a given value to avoid undesirable conditions when the switch 12 is re-closed. An asynchronous motor 14 coupled to an exciter machine 15, Fig. 3, has its exciting circuit opened by a relav 18 when the current in this circuit rises due to the opening of switch 1. A " Kramer set " comprising a flywheel motor 20 excited by a rotary converter 21 and exciter 22 coupled to the motor may be disconnected from the system bv a relay 25 when the switch 1 is opened, this relay being controlled by means responsive to the speed of the set. A frequency relay 27 may replace the governor shown in the Figure. Relays placed in suitable parts of the disconnected system may be made responsive to the changes in direction of the wattless and watt currents produced for example in the system according to Fig. 5, in which two wattless current sets 31, 32 and 33, 35 are provided in the positions shown, one being fitted with a flywheel 34.

Abstract: 144,307. Nicoson, L. C. Aug. 30, 1916, [Convention date]. Benches, work, and bench fittings.-A motor-vehicle holder comprises a pair of track supporting-rails 22 mounted on crossbars within U-shaped frames 11, 16 adapted to rock on rollers 5, 6 whereby a vehicle may be supported and tilted into any desired position for facilitating inspection and repairs. A crane 91 pivotally mounted at 81, 85 in bearing members supported by arms 83, 86 secured to the upper and lower cross-bars of the frame 16, provides means for readily removing and replacing the engine and associated parts, and a hand-winch 95 serves to enable the vehicle to be drawn into position within the support.

Title: Improved method of distilling liquids, such as mineral oils, alcohol, and the like
IPC: C10G7/00
Filed: 1920-06-03
Abstract: 154,558. Granger, L., Mariller, C., and Soc. GÚnÚrale d'Evaporation (Procedes Prache et Bouillon), (formerly Soc. Anon d'Exploitation de ProcÚdÚs Evaporatoires, (SystÞme Prache et Bouillon)). Nov. 26, 1919, [Convention date]. Generating by indirect contact of heated gases.-The condensation of vapours in apparatus for distilling crude mineral oils, volatile hydrocarbons, alcoholic liquids &c. is utilized to generate steam which may be used for heating or power-producing. When distilling liquids with a boiling-point lower than water, steam is generated under reduced pressure and may be compressed. As applied to a continuous apparatus for distilling crude mineral oil, the oil is passed by a pipe 1, through a dephlegmator D, a water separator E and a preheater F to a column A in which petrol vapours are driven off and condensed in the dephlegmator D. The oil passes from the column A through a pipe 9, heater I and pipe 14 to a column B. The oil passes from the base of the column to a boiler C, the residues from which pass to the preheater F. Vapours pass from the column B by three pipes 11, 12, 13. The heavy vapours from ripe 13 are condensed in the heater I. The vapours from the pipe 12 pass to a steam-generator K of the type in which water is circulated rapidly through a number of tubes, either by heat action in inclined tubes or by a pump or impeller, so that steam will be generated when the temperature of the vapours is only slightly above the boiling point of water under the pressure maintained in the generator. The light vapours from the pipe 11 pass to a second steam-generator L of the same type. The steam from the generator K may be used in the heater G, the condensed water from which is returned to the generator K by a pump P. Residual steam and the steam from the generator L pass to a cylinder M, from which the steam may pass for the production of motive power, or may be compressed by a device T and used for heating purposes. The various oil condensates pass through a refrigerator J to the test glasses H. In non-continuous apparatus the vapours from a still are passed on their way to a condenser through a steam generator which is kept for example under a pressure of 6 atmospheres, so that steam is generated at about 150‹ C. by vapours at a temperature slightly above this, namely, about 163-165‹ C.

Abstract: 635,917. Radio receiving apparatus; generating high-frequency oscillations. GENERAL ELECTRIC CO., Ltd., and LAMONT, H. R. L. June 16, 1947, No. 15867. [Class 40 (v)] [Also in Group XL (b)] Apparatus for rectifying, mixing or generating harmonics of high-frequency energy comprises a hollow cylindrical resonator and a crystal contact arranged along the axis of the resonator, one element of the contact being connected to each end wall of the resonator. The crystal contact, Fig. 1, comprises a crystal element 1 soldered into a recess in a metal disc 3, and a wire whisker 4 carried by a metal rod 5. The rod 5 fits into a thick-walled tube 6 surrounded by a flanged tube 7. The flange 8 has a skirt 9 one quarter-wavelength long, concentric with the rod 5, and is secured to an insulating spacing tube 10. The rod 5 and tubes 6, 7 are extended to form a plug. The disc 3 forms the end wall of a cylindrical resonator 13, Fig. 2, drilled in a metal block 14. A socket member 19 for the crystal capsule is insulatingly carried by a cylinder 17 which screws into a collar 15 on the underside of block 14. The block 14 is of reduced thickness inside the collar 15, and the disc 8 of the crystal capsule fits into a circular hole 16, leaving an annular gap. An input guide 23 and a tuning stub (not shown) are formed as rectangular channels in the block 14, and a cover-plate 25 forms their fourth sides. The crystal capsule is held in place by a clamping ring 27. The rectified output is taken across the gap between the skirt 9 and the bottom wall of the resonator. For use as a mixer, the second high-frequency input is fed through a third wave-guide channel formed in the block 14, and the output taken across the impedance gap if the frequency is sufficiently low, or a fourth wave-guide channel is formed in the block 14. In the latter case the impedance gap is not necessary. The arrangement may be modified for harmonic generation by providing a third output waveguide channel of smaller dimensions than the input channel. The impedance gap may be omitted in this case unless a biassing voltage or impedance is required in the crystal circuit. The input and output wave-guide channels may be replaced by separate guides or coaxial lines coupled to the resonators by loops, and the tuning stub may be replaced by one or more screws projecting into the resonator. The Specification gives suitable dimensions for an arrangement for use as a detector of oscillations of wavelength 6 mms.
