Title: Improvements relating to directional gyroscopes
IPC: G01C19/00
Filed: 1938-03-24
Abstract: 513,911. Fluid-pressure servomotor-control systems. ALKAN, R. March 24, 1938, No. 9026. Convention date, June 9, 1937. [Class 135] A directional gyroscope comprises a differential fluid-pressure relay coaxially arranged within a follow-up member and consisting of a fluid circuit divided into two parts by a deformable membrane and actuated in a manner known per se by means adapted to form a sort of pneumatic or hydraulic Wheatstone bridge, the deformable membrane being integral with the follow-up member controlled by the gyroscope and which is located coaxially with the axis of rotation of the gyroscope support. A gyroscope 1 has a differential fluid-pressure relay 25 arranged within a member 9 which follows up the movements of the gyroscope relative to its support and is actuated by a servomotor 10 the control or distributing valve 15 of which is actuated by the relay 25. The rotor 1 of the gyroscope is free to rotate about perpendicular axes 2, 3, 4 in a frame 5. The latter has a depending skirt or drum 6 with cut-away edges 7, adapted to obturate. differentially slits 8, 8<1> in the follow-up member 9 also formed as a drum. The slits 8, 8<1> communicate through cavities 27 and passages 26 with chambers 23, 24 on opposite sides of a flexible membrane 25 which constitutes the effective member of the relay. The membrane 25 is connected to a rod 28 passing through a gland in a trunnion on the follow-up member. A thrust bearing 29 on the rod 28 is engaged by a lever 31 connected to the piston valve 15 by a rod 16. The servomotor 10 operates a shaft 11 through reducing gear, the shaft 11 driving the follow-up member 9 through a pinion 12 and a crown wheel 13. The chambers 23, 24 also communicate through fixed orifices 21, 22 with a conduit 20 by which compressed air is supplied to the driving nozzle 34 of the rotor. The conduit 20 communicates by means of a cavity 19 and a rotatable union with a fixed supply pipe 17. To avoid " hunting," the transmission between the relay 25 and the valve 15 is provided with a spring 33. As shown this operates on the rod 16, so that a certain free movement of the drum 6 or dead space occurs before the member 9 follows this movement. By extending the shaft 11 of the servomotor 10, a drive may be obtained for various instruments which will follow the orientation of the gyroscope.

Title: Process for the production of inactive menthol (the racemate of natural menthol)
IPC: C07C35/12
Filed: 1927-04-04
Abstract: 285,394. Rheinische Kampfer-Fabrik Ges. Feb. 15, 1927, [Convention date]. Menthol and its isomers.-The liquid menthol mixtures obtained in the hydrogenation of thymol, menthone and isomenthone are shown to consist of inactive neomenthol, an unknown inactive neoisomenthol, and some remaining inactive menthol. The mixtures are subjected to freezing-out followed by fractional distillation, whereby inactive neomenthol is separated out by congelation and solid inactive menthol bv fractional distillation, the neoisomenthol being isolated by distillation from the remaining liquid product. The inactive menthol is purified by conversion into esters or ester-acids (see Specification 289,125). Inactive neoisomenthol is produced by the hydrogenation of thymol and isomenthone preferably at temperatures below 160‹ C. According to the - examples, thymol or menthone or isomenthone is hydrogenated under pressure in the presence of a nickel catalyst. The product is fractionated and the first distillate coming over at 212-215‹ C. is cooled to obtain neomenthol; the remainder is either fractionated with more hydrogenation product or again distilled and cooled to separate the inactive menthol from the neomenthol, leaving neoisomenthol in the residue. Specifications 189,450, 213,991, 231,827, and 238,314 are referred to.

Title: Improvements in and relating to control devices for magnetic sound record carrier appliances, particularly for dictation purposes
Inventor: PIEPLOW HANS-WERNER
IPC: G11B5/004
Filed: 1958-03-26
Abstract: 833,408. Magnetic recording apparatus. GRUNDIG, M. March 26, 1958, No. 9709/58. Class 40 (2). In a magnetic record apparatus in which a record sheet is wound on to a continuously rotating drum and a transducing head is shiftable parallel to the axis of the drum, a control device renders the apparatus ineffective for transducing in the absence of a record sheet on the drum, and upon the insertion of a record sheet the drive becomes effective, the sheet is automatically wound on the drum, and when completely wound on the actuation of control elements during the driving may release the operation selected, i.e. recording or reproducing &c. The insertion of a sheet 1, Fig. 3, into an inlet duct 2 depresses a feeler 64 and closes a contact stk to operate a forward run magnet VM, Figs. 1 and 2, and causes a drum 9 to rotate. When the sheet is fully wound on the drum, the end 4 of a feeler lever resting in a groove 5 in the drum is lifted so that the end 6 of the said lever breaks a contact EK to release magnet VM and interrupt forward drive. The drive may then be restarted, for reproduction, by operation of a, starter key st1 on the apparatus or a start-stop key ms1 on the microphone. For recording a key ma1 on the microphone is operated. The transducer is traversed on a rod 63 by means of guide grooves in the record sheet, the grooves being arranged slightly obliquely on the sheet to form a continuous spiral. Operation of forward magnet VM, Fig. 2, causes a surface 22 on a flywheel shaft 21, driven by the motor 7, to be coupled to a surface 30 of a wheel on the drum shaft 3. A fast rewind is effected by throwing over the reverse run contacts mw on the microphone to operate reverse run magnet RM which draws a jockey wheel 24 into contact with a surface 23 on the shaft 21 and a surface 37 of a wheel on the drum shaft 3. When it is desired to eject a record sheet, a magnet AM, Figs. 1 and 3, is energized and opens a gap in the guides 15 to permit the record sheet to run into an outlet duct formed by sheet members 49, 50. The entry and exit of the record sheets is assisted by a wheel, coupled by a belt 65 to shaft 3, acting in conjunction with rollers 68, 69 for entry and exit, respectively. In the absence of a record sheet on the drum a feeler 51 drops into the groove 5 in the drum and closes a switch AK to operate a relay S and render various circuits of the apparatus ineffective. A nose 53 on the lever 4, 6 prevents a further sheet being inserted until the previous sheet has been ejected.
