Title: An automatic start up and shut off controller for a voltage regulator of a current generator
IPC: H02P9/24
Filed: 1948-07-23
Abstract: 649,394. Automatic voltage control systems. BLACKBURN. & GENERAL AIRCRAFT, Ltd., (formerly BLACKBURN AIRCRAFT, Ltd.)., SAUNDERS, C. G., and PIPER, R. H. July 23, 1948, No. 19788. Drawings to Specification. [Class 38 (iv)] [Also in Group XXXVII] The polarity of the contacts of a vibrating contact type of voltage regulator is reversed each time that the A.C./D.C. converter that it is regulating is started up. A coil connected across the A.C. supply to the motor moves a ratchet one step each time it is energized (see Group XXXVII). The ratchet changes over a single pole two-way micro-switch from one position to the other alternately, thus energizing either one of two polarity reversing relays connected to the regulator. A further relay is in series with both polarity reversing relays and is arranged to complete the circuit when the generator voltage rises to 80 degrees of the normal value. In a modification, the relays are omitted and a double-pole doublethrow micro-switch effects the polarity reversal directly. If the generator is to run for long periods, a timing device may momentarily interrupt the motor supply at intervals of several hours so as to actuate the microswitch.

Title: Improvements in automatic regulation of turbines from which steam is removed at an intermediate stage
IPC: F42B19/18
Filed: 1920-07-09
Abstract: 147,845. Melms & Pfenninger K.ommandit Ges. April 16, 1917, [Convention date]. Void [Published under Sect. 91 of the Act]. Regulating .-Relates to steam turbines wherein steam for heating is tapped from an intermediate stage. The low-pressure valve g is adjusted by the centrifugal governor a in the same sense as the live steam valve d of the turbine, and a governor n actuated by the pressure of the heating steam controls the valve g independently by adjusting the sleeve m of the relay f. By this means, an abnormal quantity of steam may be tapped when required, and the consequential reduced power output of the turbine may be compensated by the increased output of a turbine connected in parallel.

Filed: 1924-08-25
Abstract: 241,339. Walker, W. L. Aug. 25, 1924. Plate and tube vibrators.-A soundproducing device comprises a thin resonant shell or casing containing within it a vibratory member which is situated close to the walls of the casing and communicates its vibrations thereto, the casing also containing means for setting the vibratory member into vibration. In the construction shown, a rectangular tubular brass casing 11 contains flat vibratory members 10 - - 13 clamped so as to lie parallel to and at a short distance from the walls of the casing. The members 10 - - 13 are set into vibration by electromagnets 5, 6 supplied with alternating current or pulsating direct current through leads 28 passing through watertight glands 31. The vibrations of the members 10 - - 13 are communicated to the casing by their free ends striking anvils 22. In modifications, the casing and vibratory members are cylindrical, the latter being formed either as a complete cylinder or as two semicylinders. The vibrations may be communicated to the casing through the intervening narrow air space instead of by direct blows. The device is particularly adapted for subaqueous use and a number may be arranged at intervals along a submerged cable to mark out a navigable course, the magnets being connected in series or parallel. By varying the length &c. of the casing and vibrators the device may be timed as desired and the electrical circuit may be similarly tuned.

Title: Process for the preparation of unsaturated aldehydes
IPC: C07C45/31
Filed: 1958-06-23
Abstract: Unsaturated aldehydes of the formula <FORM:0885587/IV (b)/1> are obtained by oxidising olefines of the formula <FORM:0885587/IV (b)/2> in which n is 1-3, by reacting the olefine with from 5% to 50% by weight of mercuric sulphate based on the amount of olefine to be oxidised in the presence of aqueous sulphuric acid having a concentration of 5%-30% by weight at a temperature in the range 90 DEG C.-120 DEG C. in the presence of a large excess of a diluent gas based on the amount of olefine to be oxidised.  Suitable inert gases are, for example, nitrogen, water vapour, gaseous saturated hydrocarbons, or the olefine which is being reacted.  Examples are given of the oxidation of isobutylene to methacrolein and of a mixture of 2-methyl-1-olefines obtained by dimerisation of propene to give a mixture of 2-methylenevaleraldehyde and 3-methyl-2-methylene-butyraldehyde.
Patent GB-635927-A (GB)
Title: Improvements in or relating to the preparation of organo-silicon resins
IPC: C08G77/02
Filed: 1947-07-28
Abstract: Organo-silicon resins are prepared by heating under reflux at atmospheric pressure a tetra-(p-alkylaryl)-silicate and finally distilling off the volatile products until a film-forming product, which can be hardened by stoving, is obtained.  The necessary water for this hydrolysis is obtained by exposing the tetra-silicate to moist air either during its preparation or the heat treatment.  Such silicates may be prepared by heating ethyl orthosilicate with an appropriate phenolic body.  In examples: (1) tetra p-cresyl orthosilicate was refluxed at atmospheric pressure for 12 hours and then distilled to give 2 fractions and a residue soluble in hydrocarbon solvents and in carbon tetrachloride to give solutions which may include pigments such as titanium oxide and be applied as a coating and stoved; (2) ethyl orthosilicate was heated with 2-methyl-4-di-isobutylphenol in a moist atmosphere, the liberated alcohol being distilled off during the reaction.  After refluxing for 123 1/2 hours, the product was progressively distilled to 265 DEG C., the residue having resinous properties.ALSO:Tetra-(p-alkylaryl)-silicates may be prepared by heating ethyl orthosilicate with an appropriate phenolic body.  In an example, ethyl orthosilicate was heated with 2-methyl-4-di-isobutylphenol in a moist atmosphere, the liberated alcohol being distilled off during the reaction.

Abstract: 1,021,833. Electric selective signalling systems. WESTINGHOUSE BRAKE AND SIGNAL CO. Ltd. May 24, 1963 [May 29, 1962], No. 20621/62. Heading G4H. In a signalling system for transmitting the changes that occur in the positions of a number of switches CS1, CS2 &c., at a control station to a remote station, each change of switch position is registered in one of a pair of triggers 1A, 1B; 2A, 2B; &c. of a main store MS, the main store is scanned continuously by a binary counter BC and a diode decoding matrix DD and each time a " one " bit is discovered in the main store (indicating that a switch has changed its position since the last scan) the scan is temporarily inhibited and the count: in the binary counter BC is transmitted to the remote station, this transmission is serial in groups of three bits under control of a sub-counter SCC and is characterized in that the data is transmitted at least twice differently coded each time until two items are received at the remote station which agree with each other whereupon a comparison circuit CD emits a signal causing the discovered "one" bit in the main store to be reset to zero and the corresponding stage of a register RS to be set to " one." As described, the transmission of the twelve bits in the scanning counter BC is effected in four steps. First bits 1 to 3 are transmitted using three different frequency generators CT 1 , CT 2 , CT 3 , and then the remaining groups of three bits 4 to 6, 7 to 9 and 10 to 12 are transmitted similarly. The second transmission of the contents of counter BC is similar to the first except that the way in which the bits of each group of three bits are associated with the three frequencies is altered. The circuit described only effects one alteration and then returns to the first association but it is stated that a sequence of several alterations could be used.
