Title: Improvements relating to dynamo regulators
IPC: H02P9/22
Filed: 1936-03-03
Abstract: 471,422. Automatic control systems. C. A. V.- BOSCH, Ltd., GLASER, W. H., and WOOD, N. R. March 3, 1936, No. 6402. [Class 38 (iv)] Electromotive force.-Dynamo regulators, employing a carbon pile resistance, the pressure on which is regulated by an electromagnet responsive to variations in the output of the dynamo, are provided with means for giving greater control during increasing speed than during decreasing speed to compensate for lag in the action of the resistance. The carbon pile resistance C arranged in the exciting circuit of the dynamo is subjected to the pressure of the spring d, this pressure being varied by an opposed electromagnetic force due to the armature g acting through a lever f, and push rod e. When the speed of the dynamo is increasing, the rod e is raised by the electromagnet to reduce the pressure on the pile and contact j then engages contact l on a lever m held by friction. This short circuits resistance i so that the winding h of the electromagnet exerts its full effect. When speed is decreasing, rod e moves downwards so that contacts l, j do not engage and resistance i is then in series with winding h, thus reducing the electromagnetic effect. The contact may be held by friction in the end of the rod e. The electromagnet may be replaced or supplemented by an additional electromagnet which assists the action of the spring d, and is brought into action only when the contacts l, j are separated.

Abstract: 705,178. Resilient mountings. BRITISH THOMSON-HOUSTON CO., Ltd. Feb. 12, 1952 [March 16, 1951], No. 6429/51. Class 108(3) [Also in Group XXXV] A device for securing the relative location of two radially-spaced coaxial members 2, 3 comprises an intermediate resilient packing member 1 of closed configuration, having alternate portions nearer to and further from the axis of the members 2, 3, the shape of the portions being uniform along the whole axial length of the member, at least one of the members being recessed to accommodate the packing member 1 or part of it. The resilient packing member 1, Figs. 2 and 3, may be formed by uniting the ends of phosphor-bronze strip which has spaced slots 4. In the construction shown, the member 1 is disposed in an annular space formed by opposed channels 7, 8, is an outer housing 2 and the stator 3 of an electric motor. Instead of the recess 7 peripherally-spaced conical projections on the member 1 may engage an annular groove in the housing 2, Fig. 5 (not shown). The member 1 may, if it is of the same width as the stator 3, be locaeed either by an inwardly-projecting flange or by peripherally-spaced inwardly-projecting lugs, Fig. 6 (not shown). Instead of the member 1 being slotted to cause it to assume a polygonal configuration, it may be suitably preformed. It may be of corrugated instead of polygonal configuration. Specification 647,187, [Group XXII], is referred to.

Title: Improvements in and relating to a liquid atomizing apparatus
IPC: F23D11/00
Filed: 1949-03-09
Abstract: 670,787. Spray-producers. RYE, S. O. March 9, 1949 [March 16, 1948]; No. 6476/49. Class 69 (iii) [Also in Group XI] A rotatable atomiser head 1 has a closed liquid chamber 11 with an outlet orifice 13, and liquid is fed under pressure into the chamber at points 10. The head is carried by a hollow shaft 27 which is supported in bearings 26 and rotated by an electric motor 28. The liquid, e.g. oil fuel, is delivered at 48 and passes between the shaft 27 and a stationary tube 23 to a space 39 from which it passes through one-way suction valves to pumping spaces 3. From the latter the liquid is forced through passages 10 into the chamber 11 by pistons 5 held against an eccentrically mounted disc 20. Rotation of the head causes reciprocation of the pistons and opens one-way pressure valves leading to the passages 10. A needle valve 14 is withdrawn' from the outlet orifice by the pressure of liquid in the chamber 11 which acts against a plate 15 and spring 34. A hub 80 carries a blower impeller 35 which forces air through an annular passage 36, the quantity of air, which enters the apparatus at 32 and passes through an adjustable opening 47, being controlled in accordance with the quantity of liquid supplied by the pump mechanism. The eccentricity of the disc 20, and hence the stroke of the pistons may be adjusted by slightly turning the eccentrically positioned rod 22 which supports the disc.

Abstract: 1474652 Door handles and locks YOSHIDA KOGYO KK 18 Feb 1975 [20 Feb 1974] 6765/75 Heading E2A A door locking device has a pair of knobs rotatably supported on the inside and outside of a door and an actuator rod normally rotatable by both knobs e.g. to withdraw a latch bolt, the inside knob having a push button depressible to disengage the outside knob from the actuator rod so that the door is unopenable from outside unless a lock assembly in the outside knob is unlocked. As shown in Fig. 1, an inside knob 15 and an outside knob 16 are rotatably coaxially mounted on door 12. An actuator rod 19 passes through and is rotatable with knob 15 and carries part 26 of a first clutch 24 and a grooved part 36 of a second clutch 32. Rod 19 may be pushed inwardly by push-button 20 against spring 30, disengaging part 26 of clutch 24 from a part 25 thereof on the inner end of shaft 14 of outside knob 16. Button 20 is rotatable relative to rod 19 to retain it in its inner position by L-shaped slot 22 engaging pin 23 on the inside of knob 15. Outer knob 16 can no longer rotate rod 19 via clutch 24 to open the door.

Abstract: The invention comprises a process for the production of aromatic monocarboxylic acids by the catalytic oxidation of cumene or an aromatic hydrocarbon having the formula <FORM:0816420/IV (b)/1> where n=1-5, x=0-4, x not being more than 1 when n exceeds 1, the oxidation being conducted in a reactor, from which is obtained an effluent comprising the desired acid, undesired by-product and unoxidized hydrocarbon, the steps comprising contacting the effluent with an aqueous solvent having a pH of 5-9, thus to form a first aqueous phase, and a first organic phase, separating these phases, contacting at least a portion of the first organic phase with a second aqueous solvent having a pH of at least 10, separating the second organic and aqueous phases so formed, returning the second organic phase and the remainder, if any, of the first organic phase to the reactor as part of the aromatic hydrocarbon fed thereto, and recovering aromatic monocarboxylic acid from the first aqueous phase.  A third or half of the reactor effluent is preferably subjected to the second extraction step, the remainder being directly recycled to the reactor after the first extraction step.  Suitable solvents which may be used in the first extraction are solutions of alkali metal carbonates, bicarbonates, or hydroxides, especially sodium bicarbonate, and the amount of aqueous solvent used for the first extraction should be enough to neutralize and dissolve all the monocarboxylic acid in the reactor effluent being treated.  The aqueous solvent used in the second extractor is preferably sodium hydroxide.  The process may be carried out batchwise or continuously and the two extractor units should be effective liquid-liquid contactors, preferably adapted for countercurrent flow.  Examples are given of the oxidation of o-xylene and p-tert.-butyl toluene in the presence of cobaltous 2-ethyl hexoate, to toluic and p-tert.-butyl benzoic acid respectively.
