Filed: 1931-07-31
Abstract: 376,522. Master control of A.C. motors ; controllers. SEEGER, E. W., Wauwatosa, Wisconsin, U.S.A. July 31, 1931, No. 21944. Convention date, Aug. 4, 1930. [Class 38 (iii).] Combination of resistances.-The motor 1 of a printing press has its rotor resistance R arranged in sections the values of which are in geometrical progression, the combinations of the sections being preselected by a switch 13 controlling electromagnetic switches 10, 11, 12. Depression of " run " button 18 causes relays 14, 15 to pick up. Relay 15 completes a maintaining circuit for itself over "stop" and " reverse " buttons 16, 17 and also energizes forward contactor 8. Relay 14 short-circuits sufficient of the rotor resistance R to give the motor the necessary starting torque. Release of " run " button 18 causes relay 14 to open, but completes a circuit, over the maintaining contacts of relay 15, to the switch 13, so that switches 10, 11, 12 are effective to adjust the resistance R to a value selected by the switch 13. If the "run" button 18 is locked in an intermediate position, the circuit for switch 13 is not completed and and the motor runs at low speed with all resistance R in circuit. "Inch" button 19 when depressed causes closure of relay 14 and forward contactor 8, but opens both upon release. Similarly "reverse" button 17 controls relay 14 and reverse contactor 9.

Abstract: 1509906 Temperature controlled systems T I DOMESTIC APPLIANCES Ltd 15 July 1975 [17 May 1974] 22042/74 Heading G4N [Also in Division H1] A tumbler dryer includes means for storing a signal representing the exhaust temperature reached after a preset interval following energization, means for sensing when a predetermined temperature rise has been reached, equivalent to the articles in the tumbler dryer being in a "damp dry" condition, and means for switching off the heater at this stage. In an electronic embodiment (Fig. 9) the exhaust temperature is sensed by, e.g. a thermistor or thermocouple 14 and fed to a memory device 15 through a switch 16. After a preset time delay set in at 17, switch 16 is operated to feed the output from sensor 14 to a comparator 18, together with the last signal stored in memory 15. When the difference reaches a value set in at 19, a trigger 20 operates to cut off heater 21. In a mechanical embodiment (Fig. 5) a phial 2 sensing the exhaust temperature of the dryer varies the pressure in a bellows 1 to displace a rod 3 attached to a lever 4, pivoted at one end to a slide 5 and attached by magnets 9, 9<SP>1</SP> to a pivoted second lever 8. Initial expansion of bellows 1 as the exhust temperature rises moves the slide 5 along a guide 6 against spring 11. After a preset time delay a solenoid 7 is energized to lock slide 5 on guide 6. Further temperature rise pivots both levers 4, 8 about slide 5 until lever 8 butts up against an adjustable stop 13 and further expansion of bellows 1 moves lever 4 away from lever 8, separating switch contacts 10, 10<SP>1</SP> to de-energize the heating circuit.

Abstract: Tars, mineral oils, and their hydrogenation products are cracked to obtain products of lower boiling point in presence of catalysts comprising metals or their compounds of Groups 5 to 7 of the periodic system, in the form of fine grains of size less than 1 mm. together with acid substances, particularly acids or acid salts or substances forming same under the reaction conditions, but in the absence of carriers for said catalytic substances. Vanadium, chromium, molybdenum, tungsten manganese or their sulphides, halides, or carbonates in amounts up to 5 per cent are specified while the acid substances include halogen hydracids, sulphuric, sulphurous, nitric, phosphoric and organic acids, e.g. acetic acid or sulphonic acids, acid phosphates, sulphates and bisulphites, organic halogen compounds, e.g. chloroform, iodoform, bromoform, halogen compounds of benzene, methylene, and ethylene. The acid substances are added preferably after the materials have been heated to reaction temperature which may be from 300--700 DEG  C. with a reaction time of 5 minutes to 1 hour.  Topped crude oil mixed with 0,08 per cent finely pulverulent metallic chromium, recovered by electrolysis, is heated to 450 DEG  C. in a coil preheater under a pressure of 30 atmos. and then led after addition of 0,4 per cent ethylene chloride into a reaction vessel.  The products are passed into a separator in which 26 per cent of the products are separated in the form of an oil boiling above 325 DEG  C., while the remaining vapours are condensed to give 32 per cent benzines and 42 per cent middle oil.

Abstract: 1536211 Electrowinning manganese UNIVERSITE LIBRE DE BRUXELLES 27 May 1976 [27 May 1975] 22105/76 Heading C7B Ferromanganese is contacted with an iron chloride in the presence of molten electrolytically inert chloride(s) (e.g. of Na and Ca) to obtain a liquid rich in Mn chloride and a solid Fe-containing precipitate, the liquid being optionally contacted with more FeMn and then electrolyzed. The liquid may pass through the cathode compartment and the solids through the anode compartment whereby Fe chloride is anodically regenerated. The contacting may be effected in the anode compartment by adding FeMn whereby the Fe chloride is generated in situ, the anolyte obtained being freed of solids and passed to a non-electrolytic contacting step where more FeMn is added to remove excess Fe chloride and the final liquid used as catholyte. Alternatively C12 generated anodically may be used externally of the cell to regenerate Fe chlorides from the Fe-containing solids.
