Title: New eucalyptol derivatives
Inventor: VALETTE RAYMOND
IPC: C07D311/00
Filed: 1963-07-18
Abstract: The invention comprises eucalyptol sulphonic acids and their salts. Eucalyptol disulphonic acid and its sodium salts are the preferred compounds.  They may be obtained by sulphonating eucalyptol with SO3 in the presence of dioxane, and an inert organic solvent at below 0 DEG  C.  This process may be carried out in three ways.  In all, the SO3 is initially in the form of a solution in an inert organic solvent. (1) the solution of SO3 is added to a mixture of dioxane and eucalyptol at below 0 DEG  C.  (2) A dioxane-SO3 complex is initially prepared from the solution of SO3 at between 5 DEG  and 10 DEG  C., and the complex is added at below 0 DEG  C.  (3) The method is similar to (2) except that the eucalyptol is added to the dioxane-SO3 complex.  The products have therapeutic properties and may be used in association with conventional carriers as pharmaceutical compositions. The compositions may be administered in a form suitable for oral, parenteral, or rectal administration, e.g. in aqueous solution.

Abstract: 464,476. Meshing-screw engines. AKTIEBOLAGET MILO. Oct. 16, 1935, No. 28618. Convention date, Feb. 12. [A Specification was laid open to inspection under Sect. 91 of the Acts, April 17, 1936.] [Class 110 (ii)] The engine or compressor has rotors 410, 412, geared externally by gears 442, 444, so that the helical threads on the rotor do not make contact with one another. The pressure side a of a convex thread has a smaller radius of curvature than the curve b on the suction side (in the case of a compressor). Roller bearings 416, 418, take up the radial pressure, and ball bearings 424 the axial pressure. Internal cooling of the rotors is secured by means of holllow shafts provided with concentric internal tubes 446, 448, respectively. Cooling liquid is introduced by nozzles 450 into the interior tubes, and returns outside these tubes into the spaces 460. Inlet and outlet ports 462, 464, for the compressor, are provided. Radial bores 466, 470, prevent suction of lubricant into the compressor casing, and penetration of compressed medium into the bearings at the H.P. end, respectively. The top circle 474 of the smaller rotor, and the root circle of the greater rotor, coincide with the pitch circle. The constructions of a thread T and a recess R are described, to secure efficient meshing of the rotors. The rotors may be made shorter than the pitch of the threads, and the inlet and outlet ports extended to embrace parts of the end plates. Fig. 5 shows a view of the pressure end with a plate 502 provided to limit the edge of the delivery port. The bounding line of the axial port is described in the Specification, and is developed to fit the shapes of the threads and recesses of the rotors. Similarly the inlet port may be extended to embrace part of the end plate in the L.P. end. To prevent fluid being trapped by a tooth in a recess R, a small passage may be provided, which leads to the delivery port. In Fig. 1 the portion of the rotors located to the left of lines 510, 514, 512, is completely enclosed by the casing, while that to the right is in communication with the inlet 462.

Filed: 1974-07-02
Abstract: 1450229 Stopping machines at definite positions ROCKWELL GOLDE GmbH 2 July 1974 [2 July 1973] 29262/74 Heading F2E A shaft 1, carrying a drive pinion 3 which operates a vehicle roof which is both pivotable and slidable for example, is journalled at 10, 11, in a fixed rosette block 7 for rotation by a crank arm 5 and crank foot 4, Fig. 1. An eccentric disc 14 integral with the shaft 1 whose axis is at a distance e, Fig. 2, from the shaft axis, journals a toothed ring 16, Fig. 1, having external teeth 15 two fewer in number than internal teeth 17, with which they mesh, provided in the rosette block 7. The tooth root radius of teeth 17 exceeds by approximately the eccentricity e the tooth tip radius of teeth 15. When the eccentric disc 14 is rotated, it causes toothed ring 16 to rotate, but only by a distance of two teeth for each revolution of disc 14, and in the opposite direction, in known manner. Abutment means associated with the toothed ring co-operate with abutment means connected to the rosette block for limiting shaft rotation after a predetermined number of revolutions as described below, and the invention is concerned with the lastmentioned abutment means, which comprises a locking pin 19, Fig. 2, slidable parallel to shaft 1 and controlling rotation and stopping of the toothed ring. As shown, (a) locking ring 28 is journalled on an annular projection 30 of the rosette block 7 and has an annular shoulder 33, Fig. 6, having a gap 34 normally occupied by one end of pin 19, as seen in Fig. 1, two peripheral steps 31, 32, together forming the first-mentioned abutment means, and a radial groove 35. The toothed ring 16 has a driver pin 36, Fig. 2 (not shown in Fig. 1, but extending leftwards in the orientation of that figure) always engaged in groove 35 of locking ring 28. The locking pin 19 is spring- urged leftwards in a guide sleeve 18 fixed in rosette block 7; the outer end of sleeve 18 is accommodated in an annular groove 42 in crank foot 4 to permit rotation of the latter. In operation, a catch bolt 39 is pushed inwards in a fixed catch sleeve 38, Fig. 7, whereupon arms 48 of a clip spring 47, Fig. 8, engage a second arrester recess 49 to retain the bolt temporarily. The locking pin 19 has been thereby pushed in so that a transverse recess 23 on it, Fig. 1, is aligned with shoulder 33 on locking ring 28, as seen in Fig. 9. As soon as rotation of crank assembly 5, 4, is begun, pin 19 is retained in the Fig. 9 position by shoulder 33, while bolt 39 is returned to the Fig. 9 (or Fig. 1) position by engagement with conical surface 57 in sleeve 18. Assuming shaft 1 is being rotated counterclockwise, as seen in Fig. 2, locking ring 28 is driven clockwise, until peripheral step 31 on it encounters locking pin 19, whereupon rotation of shaft 1 is arrested.

[Class 123 (iii).] To prevent overheating the superheater tubes 7 arranged along a wall of a boiler furnace and to regulate the superheat, the boiler steam is forced through the tubes by a compresser or turbo-blower 11, and the superheated steam main 21 is connected to the boiler steam space by a pipe 22. The speed of the turbine 17 driving the blower is controlled by a thermostat 9 in the superheater outlet header. The thermostat operates a valve 18 in the turbine steam supply pipe 15 which is branched from the steam pipe 10 leading from the boiler steam drum 3 to the blower. The steam returned to the boiler drum through the pipe 22 is discharged through a horizontal perforated pipe 24 arranged behind a baffle 26 extending below the water level in the drum and terminating short of the ends of the drum. Steam from another source may be supplied to the superheater through a pipe 27 while'the boiler is being started up. A valve in a byepass 14 is opened to allow steam to flow directly to the superheater when the turbo-blower is out of action. In a modification, the steam valve of the turbine is operated in accordance with the drop in pressure through the superheater, and the return-of steam through the pipe 22 is controlled by a valve operated by a thermostat in the superheated steam header 19.

Abstract: 435,649. Combined sound and picture films. SIEMENS & HALSKE AKT.-GES., Siemensstadt, Berlin. Oct. 12, 1934, No. 29289. Convention date, Jan. 15. [Class 40 (ii)] Relates to the use of lenticular films for the production of combined kinematographic and sound records, and particularly to films (suitable for the production of coloured, stereoscopic, and like pictures) in which cylindrical lenticulations are inclined at an angle to the longitudinal direction of the film. According to the invention, in order to prevent audible interference with the sound reproduction from being caused by the lenticulations, these are so arranged that the condition expressed by the formula cos alpha ##o/Nhn is satisfied, where alpha is the angle between a line extending transversely to the film and the axial direction of the cylindrical lenticulations, fo is the highest audible frequency in the sound to be reproduced, N is the number of pictures shown per second, h is the picture height in millimetres, and n is the number of screen lenses per millimetre. The sound-reproducing apparatus used is such as to suppress frequencies above 5000 to 6000 cycles per second, e.g. by the use of a suitable filter. The sound is preferably recorded by exposure of the film at the smooth side.
