Title: Manufacture of water-soluble compounds of the androstane and pregnane series
IPC: C07J1/00
Filed: 1936-11-25
Abstract: Water-soluble compounds of the androstane and pregnane series which contain at least four substituents containing oxygen of which at least three are hydroxyl groups are obtained, (a) by attaching a pair of hydroxyl groups either directly or through the intermediary of an oxygen bridge to the double linkage or linkages of a mono- or poly-unsaturated compound of the androstane or pregnane series, or (b) by reducing the keto group or groups in a saturated or unsaturated oxyketone or polyketone of the androstane or pregnane series.  The compounds treated as above may contain free or substituted, for instance, esterified or etherified hydroxyl groups and/or keto groups.  The methods which are used for the treatment (a) above are those described in Houben-Weyl, "Methoden der organischen chemie," Volumes II and III.  The preferred methods for attaching hydroxyl groups are by the action of hydrogen peroxide, if desired in the presence of a catalyst such as an acid, a salt, or osmium tetroxide, or by osmium oxide alone, or by an oxidizing agent such as permanganate. If the procedure is by way of an oxygen bridge, this may be opened by treatment with water, if desired in the presence of an acid. The reduction process (b) above may be carried out in acid, neutral or alkaline medium.  Parent materials for use in carrying out the present invention which are mentioned are the dehydroandrosterones, androstene-diols, testosterones, androstene-diones, pregnenolones, pregnendiols, progesterone, 17-vinyl-androstene-3 : 17-diol, 17-vinyl-androstane-3 : 17-diol, bis-dehydro-compounds of the androstane and pregnane series, 7-oxy-, or 7-keto-dehydroandrosterone, and oxygen, halogen, or halogen-hydrin addition products of correspondingly unsaturated compounds, as well as esters, enol-esters, or ethers of these compounds, and their stereoisomerides.  In examples: (1) a glacial acetic acid solution of D 5-trans-dehydroandrosterone acetate is treated with hydrogen peroxide, and then after the removal of the solvent is saponified with methyl alcoholic potash to give 3 : 5 : 6-trioxyandrostanone-17. Instead of the D 5-transdehydroandrosterone, the D 4-compound or an ester thereof may be used; (2) a chloroform solution of trans-dehydroandrosterone is treated with a chloroform solution of perbenzoic acid for 40 hours at 5 DEG  C.  The oxide so obtained is heated with water under pressure at 110-115 DEG  C. to give 3 : 5 : 6-trioxy-androstanone-17; (3) a glacial acetic acid solution of D 5-androstene-3 : 17-diol-diacetate is treated with hydrogen peroxide, and after removal of the solvent, the product is saponified to give 3 : 5 : 6 : 17-tetroxy-androstane.  The same compound is obtained by starting with androstene-diol and its mono-esters, or by reducing with aluminium isopropylate the androstane-trione-(3 : 6 : 17)-ol-(5) which is obtained by oxidation of D 5-androstene-diol with chromic acid.

Title: Improvements in or relating to hydraulic valves
Inventor: ERICSON DONALD WALLACE
IPC: F15B13/043
Filed: 1960-09-21
Abstract: 895,543. Fluid-pressure servomotor-control systems. PEGASUS LABORATORIES Inc. sept. 21, 1960, No. 32372/60. Class 135. An hydraulic control valve 42 is provided in a casing 22 housing an input device formed by field coils 31, 32 and an axially movable armature 33 mounted on a shaft 34 between a pair of leaf springs 35, 36 ; movement of the armature 33 is proportional to the electric signal applied to the coils 31, 32 or the difference between separate signals fed to each coil. The valve 42 comprises a spool with lands 44-47, the spool having a central axial bore 48 embodying a pair of filters 50, two internal orifices 51, 52 and two discharge nozzles 54, 55 extending into chambers 56, 57, respectively. Fluid is supplied to the casing 22 via a port 60 and is exhausted therefrom through a port 61 ; a port 62 in the spool enables fluid from the inlet to enter the bore 48 where it divides and flows equally through the orifices and nozzles to chambers 56, 57. The spool which controls the flow of fluid to either of two outlet ports 66, 67 is positioned by the armature through the action of two closures 70, 71 which regulate the flow from the nozzles 54, 55 and hence the pressure in the parts of bore 48 between each orifice and the associated nozzle, which pressure is conducted via ports 83, 85 to act on the end surfaces of the outer lands 44, 47, respectively. The closures 70, 71, which are each adjustably secured by a flexible member or wire 76 to a different one of the ends of shaft 34, are each pivotally mounted by a plane or reinforced metallic diaphragm 80, which also prevents fluid from entering that part of the casing housing the input device. Return movement of the armature is assisted by springs 88, 89 acting on the closure 70, as well as by the leaf springs 35. The closures 70, 71 are arranged with variable fulcra and with parts which cooperate with the nozzles which are adjustable relative to the latter without altering the closure positions.

Title: Improvements in or relating to telegraph printing systems
IPC: H03M7/40
Filed: 1919-12-29
Abstract: 160,916. Automatic Telephone Manufacturing Co., Ltd., Harrison, H. H., and Smith, S. R. Dec. 29, 1919. Type - printing telegraphs. - Relates to means whereby messages transmitted over a highcapacity system employing either the Morse or five-unit alphabets may be automatically retransmitted over a secondary, low-capacity system employing, for instance, step - by - step printing telegraphs, and vice versa. The method of interlinking the two systems comprises a storage device, such as a tape, for receiving and recording signals from one system, and a translating-device, controlled by the tape, for effecting the generation of signals in the code appropriate to the other system. As shown in Fig. 1, messages recorded on a tape in the five-unit code are converted into corresponding signals in a step-by-step printing system. The passage of the tape through feelers 10 actuates a series of setting-magnets 11 - - 15 to select a particular one of a series of cross-bars 22 through the medium of the permutation bars 16 - - 20 in the usual manner. A universal bar magnet 23, in series with the setting-magnets, causes the chosen cross-bar to close a contact at 25 and thereby energize the corresponding segment 31 of a distributor 28. Coaxial with the distributor are (1) a cam-wheel 26 which causes a contact 33 to send a successive series of positive and negative impulses to line 34 from the batteries 35, 36, and (2) a detent wheel 29. When the rotating arm 27 of the distributor passes over an energized segment 31 it completes the circuit of a relay 39 and causes the arm 41 to arrest the detent wheel 29 and consequently the cam-wheel 26, so that a prolonged impulse is sent to line 34. This prolonged impulse operates the magnet 37 to close a circuit through the feed-magnet 42, so as to advance the tape one step and to re-set the bars 22 through the magnet 23. The successive series of positive and negative impulses sent to line through the contact arms 33 oscillates the tongue 44. Fig. 2, of a polarized relay 43, and thereby actuates the escapement arm 49 of two escapement wheels 50, 51 on a shaft 52 carrying the type wheel 53. A prolonged impulse causes (1) a printing-magnet 47 to swing the hammer 66 against the selected letter on the type-wheel 53 and (2) a relay 48 to close the circuit of a punch magnet 67. If it is desired to convert the stepby-step signals from the line 34 into signals on the five-unit code, this is effected by means of commutators 54 - - 58, each of which controls corresponding punch-selecting magnets 59 - - 63, through circuits which comprise a battery, brush 64, slip-ring 65 and the unshaded segments of the commutators. When the punch magnet 67 is actuated, a tape is punched according to the particular arrangement of the magnets 59 - - 63 selected by the commutator and determined by the incoming signals.

Abstract: 245,150. Deutsche Gasgluhlicht-Auer- Ges. Dec. 24, 1924, [Convention date]. Void [Published under Sect. 91 of the Acts]. Switches, quick-action; thermal switches.-A tumbler switch is moved " on " or " off " by the movement of a bimetallic strip. The bimetallic strip carries a contact e which when the strip is heated, bears against a contact on the operating arm b of the tumbler switch, moving the arm about a pivot c and a spring d over deadcentres to cause a quick break. The strip may carry an extension member to return the switch to its " on " position or the strip may be longitudinally split and arranged so that one part will move the switch " off " and the other " on " or the switch may be moved " on " by a press button. Several bimetallic strips may be combined together as to cause a bigger displacement of the operating portion for a given change of temperature.

Title: Sheet feeding mechanism
IPC: G03G15/30
Filed: 1961-12-23
Abstract: 1,015,636. Feeding sheets. RANK XEROX Ltd. Dec. 23, 1961 [Dec. 23, 1960], No. 32534/65. Divided out of 1,015,633. Heading B6B. [Also in Division G2] In an electrophotographic apparatus (see Divisions G2-G3) sheet material is fed into contact with a xerographic drum at an image transfer station. A supply of sheets 301, Fig. 5, to be fed one at a time to a sheet conveyer 43, is positioned in a slidable tray 41 mounted on drawer slides such as 302. The tray 41 has a platform 304; Fig. 13 (not shown), side walls 305, and an end wall 306. To provide sheet separation of the topmost sheet, sheet separators e.g. 308, Fig. 14, act at adjacent sheet corners. Each separator has a vertical stop 311 with an inturned lip urged into contact with the topmost sheet by a spring 313. Cam followers 314 secured to the separators are lifted by cams 315, Fig. 13 (not shown), thereby facilitating the introduction of a new stack in the tray upon withdrawal of the tray on the drawer slides. A gate 316 aligns the sheets prior to the engagement of the separators. The gate is swung downwards by a cam 319 upon advance of the tray. A driven separator roller 42, Fig. 21, of rubber is secured to a core 323, Fig. 12 (not shown), mounted by a slip clutch 324 on a driven shaft SH-9, Fig. 21. Shaft SH-9 is driven by a belt 326 from a shaft SH-8 within a tube 333 oscillated by a lever 335 to bring the roller 42 into contact with the topmost sheet to feed this sheet to sheet guide 39, Fig. 5. The leading edge of the fed sheet is arrested by a pivotally mounted gate 355, Fig. 14, thus causing buckling of the sheet. A sheet gripper 44 actuates the gate 355 to release a sheet so held to permit the sheet to be gripped by the gripper. Conveyer 43, Fig. 5, includes two endless roller chains 361, Fig. 11 (not shown), passing around drive sprockets 362, 365, Fig. 5. The chains carry the sheet grippers 44 as described in Specification No. 1,015,634, equally spaced from each other along the length of the chains. The chains are driven in synchronism with the xerographic drum 20 by the drive mechanism of Fig. 6 (not shown). After receiving a powder image from the drum 20, Fig. 5, sheets are passed through a heat fuser 46 and are delivered by rollers 48, 47, Fig. 11 (not shown). Similar rollers 49 feed a sheet inadequately gripped by grippers 44 out of the apparatus to a guide 50.
