Title: Method of preparing a therapeutic agent effective against malaria
IPC: A23L27/40
Filed: 1953-11-10
Abstract: A therapeutic agent effective against malaria comprises table salt coated with an anti-malarial organic compound, e.g. 2 : 4-diamino-5 - p - chlorophenyl - 6 - ethylpyrimidine ("Daraprim," Registered Trade Mark), 8-(4-amino - 1 - methylbutylamino) - 6 - methoxyquinoline (Primaquine), 7-chloro-4-(4-diethylamino - 1 - methylbutylamino) - quinoline (chloroquine), which may be present within the limits 1 : 500-5000 parts of table salt.  A layer of wax-like material e.g. polyethylene glycol having molecular weight in excess of 1000 may first be applied to the table salt and the antimalerial coated to this.  The coating operation occurs in a revolving pan, the table salt being wetted with a solution in an organic solvent of the wax, if used, dried, and then with a solution of the antimalarial salt, and then dried.

Abstract: 1,272,019. Rail vehicles. SOC. D'APPLICATIONS GENERALES D'ELECTRICITE ET DE MECANIQUE. 20 June, 1969 [31 July, 1968], No. 31334/69. Heading B7L. In rail vehicles, in which the angle of tilt # (to counteract the centrifugal forces arising on curves) of the body 1 relatively to the bogie 3 is structurally limited to a maximum # max  = I M , which is less than the value of the angle of tilt I, required for complete counteraction of the centrifugal forces, the tilting action is damped, so that the attainment of the maximum available angle of tilt I M  is postponed until the point Q, on the curved track, at which the radius of curvature becomes constant. A first detector 7 of the accelerometer type gives a signal proportional to I and a second detector 8 gives a signal proportional to #. The signal I is fed to a threshold device 9 whose output is proportional to I, but does not exceed I M . These outputs are fed into comparator 10, whose output is propor. tional to the error E (= I - 0). A differentiating device 12 and a regulating device 11 provide the input signal to an electro-hydraulic distributor, which effects the necessary tilting motion.

In the case of orifices the cross-sections of which consist of one central straight portion and two terminal straight portions, the length of the central portion of each extrusion orifice is greater than that of either terminal portion of the cross-section of the same extrusion orifice. When the slot cross-section is in the form of a central straight portion and two terminal straight portions the angle between the terminal portions and the central portion may be from 15 degrees to 150 degrees. The terminal portions of the slot cross-section may be parallel to each other. At least two of the orifices may be either orientated or disorientated with respect to an imaginary line joining their centres. Filaments formed by melt spinning a polymer such as polyethylene terephthalate through a spinneret plate having extrusion orifices according to the invention have crosssections corresponding to those of the extrusion orifices.

Indicated substituents for A and B are halogen, alkyl, alkoxy, nitro, trifluoromethyl, alkyl-, aryl- and aralkylsulphonyl, and carbonamide and sulphonamide groups, the last two of which may be N-substituted, and an additional substituent for A subject to the above proviso, is a phenylazo group in the para position to the azo link the phenyl group of which may contain the substituent indicated for B. Preferred dyes are those where B is unsubstituted and Y is NH2.  The dyes, previously dispersed, may be used at ordinary pressures in the presence of carriers, or under pressure, with or without carriers. They may be used in frame or roller printing processes or in the Vigoureux process.  Alkylaryl sulphonates, and condensation products of sulphonated aryl derivatives with aldehydes, may be present.

Fig. 1 shows part of a mimic diagram with 4 members A, each rotatable manually using a diametral bar B to control a respective valve. Fig. 2 shows one such member A, its valve F and 2 limit switches G of the valve. The member A contains 4 lamps L (two shown) visible by virtue of A being transparent or translucent, A also having an upstanding peripheral rim acting as a lens to permit observation from the side. Manual rotation of A operates a switch SW1 using a cam J, and pressing A against a spring K closes a switch SW2. Circuity M (Fig. 2) is shown in Fig. 3 including the limit switches G at MS1, MS2 and the lamps L at 20, 21, 22, 23. When the valve is fully open or fully closed, MS1 is open or MS2 is closed respectively, to give an open or closed circuit respectively via a Zener barrier ZB, to energize a relay RLA or RLB respectively, via a thresholding amplifier AMP1 or AMP2 respectively, the relay energizing a green "open" lamp 21 or a red "closed" lamp 23. If the valve is to be moved to its other position, switch SW1 is reversed, thus de-energizing lamp 21 or 23, energizing a white "opening" lamp 20 or a white "closing" lamp 22, and supplying a control voltage via 10 or 11 to the valve. As the valve moves from its fully open or fully closed position, MS1 and MS2 take the positions shown to connect resistor R10 into the circuit whereby neither amplifier AMP1, AMP2 is producing an output and both relays RLA, RLB are de-energized so neither of lamps 21, 23 is lit. When the limit is reached (fully open or fully closed) MS1, or MS2 produces the state first mentioned with 21 or 23 lit. In case of a short or open circuit in connection with MS1, MS2, switch SW2 is provided to de-energize relays RLA, RLB to permit control using SW1 irrespective of MS1, MS2.

Title: Apparatus and method for winding cores
IPC: B21C47/04
Filed: 1960-09-15
Abstract: 907,725. Making magnetic cores; winding and reeling; unwinding. WESTINGHOUSE ELECTRIC CORPORATION. Sept. 15, 1960 [Sept. 25, 1959], No. 31815/60. Classes 83 (2) and 83 (4). A method of making a wound type core from magnetic strip material comprises the steps of introducing a predetermined curvature into said strip material at each point along said strip material, and winding a plurality of turns of said strip material on a rotatable member to form a closed core loop, and so controlling the radius of said predetermined curvature during the winding operation that it is always less than the effective radius of the corresponding turn of strip as it is wound on the rotatable member. A coil 42 of magnetic steel is supported on a turntable 46 about a collapsible mandrel 70 secured to the turntable and comprising segments 74 moved outwards against springs 75 by the rotation of a cam 73 by hydraulic or pneumatic means. Suitable braking means is mounted beneath the turntable 46. Strip 44 from the coil 42 passes over a guide roll 128, on a spring-urged lever arm 126, over a flanged guide roll 134 between edge rolls 148, over a flanged guide roll 334, Fig. 3, in a housing 310, and between deburring rolls 284, 384, pressed on the edges of the strip by releasable spring means 298. The strip then passes under a microswitch assembly including a projecting member 278 normally bearing against the strip, but, if tension therein should drop, the switch is actuated to cut off the drive to a mandrel for winding the strip. The strip is then given a set by passage over a cam 272 on which slides an endless flexible belt 274 of which the tension is adjustable by screw means 398, the belt serving to protect the cam and the strip. The strip then passes to the winding-up mandrel which has an upper flange 176 and a slot into which the end of the strip is secured by turning a clamping handle 178, the lower edge of the wound strip being supported on horizontal rollers 144 in a winding table 142. In order to vary the set or radius of curvature imparted to the strip 44 by the cam 272 as the number of turns of strip wound on the mandrel increases the cam 272 is slowly rotated by adjustable linkage means 244, 256, 254 and 262 carrying a roller 264 bearing on the wound core. When the wound core attains a predetermined diameter it actuates a micro-switch 180 to stop the drive to the mandrel, whereupon the core is severed from the supply. A hinged clamp arm 162 is then closed around, but spaced from, the wound core to co-operate with a fixed clamp arm 167. The mandrel is then rotated slowly in the direction opposite that of its first rotation until the outer diameter of the wound core increases to the inner diameter of the clamp arms 162, 167. The clamp arms are then opened, the winding table 142 lowered, slipping the core off the mandrel, and the core is pushed away by an arm 152 moved by an hydraulic piston rod 154. The wound core may be shaped to have a yoke and legs and finally annealed. Specification 804,412 is referred to.
