Abstract: 512,468. Antiseptics ; medicines ; emulsions; making. DEUTSCHE HYDRIERWERKE AKT.-GES. Feb. 4, 1938, No. 3638. Convention date, Feb. 4, 1937. [Class 81 (i)] [Also in Group III] Clear stable aqueous solutions of phenols, naphthols, menthol, and substitution products of these for use as antiseptics or in medicine are prepared by using, as solution promoters, cation active substances having a soap-like action which contain high molecular alkyl groups and are derived from weak cyclic organic bases. Suitable solution promoters are quaternary ammonium compounds having a high molecular alkyl group attached to the nitrogen atom, such as alkyl pyridinium hydroxides, similar compounds derived from quinoline, isoquinoline, pyrrole, aniline &c., and the halides, sulphates, nitrates, acetates and other salts of these. According to examples (1) a mixture of chlorxylenol, p. chlor-m-cresol, chlorthymol and chlorcarvacrol is mixed with alkyl pyridinium chloride (the alkyl residue corresponds to the alkyl residue of coconut oil fatty acids), water and alcohol, to give a solution to be largely diluted with water for use ; (2) p-chlor-m-cresol or chlor-m-xylenol is formed into a solution with water and alcohol with addition of alkyl pyridinium chloride, alkyl quinolinium sulphate or alkyldimethyl phenyl ammonium bromide. Specification 393,276 is referred to. The Specification as open to inspection under Sect. 91 relates also to the preparation of aqueous solutions of insoluble or difficultly soluble substances in general, specifying camphor rotenone, pyrethrine, derivatives or substitution products thereof and vegetable extracts. An additional example relates to a solution containing camphor, lauryl-quinolinium chloride, water and alcohol. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to blast furnaces and like shaft furnaces
IPC: C21B5/00
Filed: 1950-02-13
Abstract: 678,530. Blast furnaces. LEONE, O. J., and LEONE, D. P. Feb. 13,1950, No. 3677/50. Class 72 [Also in Group XXXV] In a method of controlling a blast furnace the static pressure is measured near the bottom and near the top of the'stack and the pressure drop is controlled'to a value below that at which the furnace has a tendency to generate slipping conditions by selective variation of the temperature, pressure and rate of flow of the gases at the top and bottom of the stack. As shown, the static pressure may be measured at point 11 in the blast pipe and at point 12 in the exhaust pipe, these pressures being fed into a controller 10, which may or may not be recording, and which operates a valve 19 in the exhaust pipe to control the static pressure in the stack. The temperature of the blast may be measured by a thermostat 30 in the blast pipe, controlling the amount of air which byepasses an air heater 7. The points of measuring the pressure may be in the stack and the blast pressure may be regulated by varying the speed of the fan or by a valve in the blast pipe, Fig. 2, (not shown). The temperature of the exhaust gas may be controlled by a thermostat operating a water spray at the top of the stack, Figs. 2 and 3, (not shown). The temperature and pressure readings may be co-ordinated giving a very fine control of the static pressure in the stack. The charging bell controls may be connected to the controller so that the latter does not operate during charging periods.

IPC: G05B13/02
Filed: 1969-01-23
Abstract: 1,262,711. Optimising control. FOXBOROYOXALL Ltd. April 9, 1970 [Jan. 23, 1969], No.3975/69. Heading G3R. In a system for automatically maximising or minimising a process variable, a step change is made in the value of a controlling variable and, after a delay, the new magnitude of a controlled variable is stored and compared with its previous value so that the controlling variable is correctively adjusted in dependence on the difference, the step change being removed or retained as appropriate before the next control sequence. In atransistorized control system, Fig. 1, a multivibrator 6 periodically controls a logic circuit 5 so that an adjustable step signal is applied through a lead 14 to a control unit 9 to produce a step change in a variable MV controlling a process P. After an interval sufficient for the change to become effective, logic circuit 5 operates switches in a measuring unit 2 so that the value of a dependent process variable CV, filtered and capacitively stored at 2, is compared with its previous value similarly stored. The difference, stored at 3, is applied to control unit 9 to change the controlling variable by acorresponding amount in a corresponding sense. A discriminator 4 determines whether the difference exceeds a predetermined adjustable value, in such sense as to approach the maximum or minimum value desired and, if so, prevents, through a line 17 or 18, removal of the step change until the improvement is insufficient or negative. The step change is finally applied and removed alternately to maintain the system oscillating about the maximum or minimum. Detailed circuits which include manually adjustable controls are described.

Abstract: 490,591. Vehicle brakes. SVENSKA AKTIEBOLAGET BROMSREGULATOR. Feb. 9, 1938, No. 4113. Convention date, Feb. 11, 1937. [Class 103 (i)] In a device for automatically adjusting the braking effort applied to a vehicle according to the load on the vehicle, separate means are provided for adjusting the device from the two ends of the vehicle whereby only the means operated from that end of the vehicle which is the less heavily loaded is effective for adjusting the device, skidding of the wheels which might occur when the load is unevenly distributed being thus avoided. In Fig. 1, the lever 12 which operates a variable leverage mechanism is biassed by a spring 11 towards stops 7a, 9a on rods 7, 9 which are respectively displaced against the action of springs 10, according to the load on the respective axles B at each vehicle end by bell-cranks 6 pivoted on brackets 5, and connected to the links 4 of the springs b. The arrangement is such that if the load is unequally distributed, the lever 12 is positioned by the rod which is associated with the less heavily loaded end of the vehicle that is, as shown that of the axle B. In Fig. 2, the pivot of the lever 18 which controls the variable leverage. device is slidable in a slot 20 in the frame and the lever, which reacts against a spring 19, is connected by rods 23, 24, and bell-cranks 16 to the links 14 of the springs b. If due to unequal load on the two axles, the forces applied to the lever 18 by rods 23, 24 are unequal, the lever and rods are displaced towards the vehicle end that is more heavily loaded so that the bellcrank at that end abuts on a stop 17 and the lever 18 is then turned only by the bell-crank at the less heavily loaded end of the vehicle.

Title: Collimator for high energy radiation beams
IPC: G21K1/04
Filed: 1961-02-06
Abstract: 912,084. Collimators for high-energy radiation beams. AVIATION ELECTRIC Ltd. Feb. 6, 1961 [Feb. 8, 1960], No. 4333/61. Class 98 (1). A collimator for high-energy beams consists of an inner and an outer ring of leaves, each ring comprising at least three leaves, the leaves extending in a direction away from the source and of adjustable inclination thereto, and the rings being so arranged that gaps between leaves of the inner ring are covered by leaves of the outer ring. The form shown has four inner leaves 6 and four outer leaves 5 mounted on a base 1, the adjustment of the leaves being effected by a milled ring 2. Fig. 7 shows one form of mechanism by which the leaves can be moved. As ring 2 turns, rack teeth on it rotate a bevel gear 17 on a shaft 18. The other end of the shaft is threaded, as at 21, engaging in a threaded hole 20 in a housing 31 ending in a bar 11. As the threaded part 21 screws into and out of the housing 31, the bar portion 11 pushes against the leaf 6, causing it to swing about its pivot 25. A similar arrangement moves the leaf 5 about its pivot. Fig. 8 (not shown) is an alternative form of mechanism for linking the ring 2 with the leaves 5 and 6. The construction and shape of the individual leaves are shown in Figs. 5 and 6. The outer leaves 5 have extended edges 45, 46, and the inner leaves have extended edges 47, 48, so that they may overlap in all but the most open positions. At the end farthest from the radioactive source 40 the leaves 6 have an extended tongue portion 58, and the leaves 5 a relieved surface formation 71 into which this tongue portion may fit. The inner surface of the leaves may be plated with chromium or copper to minimize the production of secondary electrons.
