Title: Sterol compounds and processes for preparing same
IPC: C07J5/00
Filed: 1938-07-26
Abstract: 516,845. Sex hormones. PARKE, DAVIS, & CO. July 26, 1938, No. 22223. Convention date, Aug. 6, 1937. [Class 2 (iii)] The particular isomer of pregnanol-3-one-20 which melts at 149‹C. is prepared from isopregnandiol-3:20 melting at 174‹C. by protecting the 3-hydroxyl group by esterification followed by oxidation and hydrolysis. The preferred method of production is by acetylation. The parent material is made by catalytically hydrogenating pregnandione of melting point 120‹C., preferably in the presence of platinum oxide. In an example an acetic acid solution of isopregnandiol is refluxed with acetic anhydride for 3 hours and then oxidized with chromic acid. The reaction product is worked up by extraction with ether and reaction with betaine hydrazide chloride to remove the ketone compound from non-ketonic products. The final product' is then purified by formation of its acid succinate and by means of digitonine to the pure pregnanolone melting at 149‹C. It forms an acetate melting at 121‹C. and a semicarbazone melting at 245‹C. Specification 431,833 is referred to. The Specification as open to inspection under Sect. 91 describes generally the conversion of any pregnandiol or allopregnandial compounds into the corresponding pregnanolone compounds, and includes examples of the treatment of other pregnandiols than the ones described above by similar oxidation methods. This subject-matter does not appear in the Specification as accepted.

IPC: G05D3/18
Filed: 1951-09-24
Abstract: 750,294. Electric control systems. NATIONAL RESEARCH DEVELOPMENT CORPORATION. Sept. 18, 1952 [Sept. 24, 1951], No. 22303/51. Class 40(1) [Also in Group XIX] In apparatus for positioning a moving member relative to a number of contact segments the driving means is a moving coil fed by an amplifier whose input is a function of the timing of a pulse signal representing the relative position of the moving member and the bank of contact segments, and a signal defining a required positional relationship. As shown (Fig. 1). a carriage 6 rigidly coupled by rods 59 to a coil 7 movable in   a steady magnetic field 60 runs between guides 65 and carries a vane 8 capacitatively coupled at one end to a plate 9 and at the other end to a series of 45 spaced segments 11. Each segment is supplied from a generator 82 with a train of pulses p0, p1, &c. (Figs. 2a-2f), so that each segment receives a pulse in sequence cyclically from a generator 82 comprising 45 trigger and gate circuits 83 fed with pulses on lead 84 from an oscillator 87 and pulse squares 86, the pulses being directed through each gate circuit in succession to the individual segments 11. Thus, with the pick-up vane 8 mid-way between two segments, the input to an amplifier 12 is as shown in Fig. 2h. This signal is fed to a discriminator 14 together with a signal from a variable edge voltage generator 15 comprising a square shaped voltage of + 120v for one cycle followed by +80v for one cycle (Fig. 2i), repeated continuously, the position of the voltage change being determined manually or by 'means of a six-figure binary code signal derived from e.g. a digital computing machine. When the voltage in the pick-up vane 8 from the segments 11 is symmetrical with respect to the preadjusted edge of the output of the variable edge generator 15 the resultant current in coil 7 is zero, and the coil and attached carriage 6 comes to rest. The vane 8 may alternatively be brought to rest opposite a segment 11 by applying suitable delay to the variable edge voltage. As shown the carriage 6 is attached to a pick-up head 62 associated with a rotatable drum 64 furnished with 45 recording tracks 74.

Title: Improved process and apparatus for the automatic operation of the air-exhausting apparatus in mercury vapour rectifiers
IPC: F04F9/08
Filed: 1923-09-06
Abstract: 203,702. Akt.-Ges. Brown, Boveri, et Cie. Sept. 9, 1922, [Convention date]. Regulating or controlling action.-In a process for automatically controlling the exhausting apparatus of a mercury-vapour rectifier, the stopcock between the rectifier and the vacuum pumps is opened after the pumps have been running for some time. For this purpose a solenoid g opening the stop-cock h between the rectifier a and a high-vacuum mercury-vapour jet-ejector d is controlled by a delayed action relay o in the circuit of the heater e of the ejector, and by a similar relay r in the circuit of a motor b driving a low-vacuum rotary pump c. When the vacuum falls below a certain limit determined by a contact i in a vacuum meter f, the winding m is energized and closes the circuit of the heating-coil e and relay winding o. A period of 10 to 15 minutes necessary for heating the pump elapses before the contacts of the relay o are closed through a solenoid p controlling the switch p of the motor b. A relay winding r in the motor circuit closes its contacts after about 3 minutes and thereby energizes the solenoid g to open the stop-cock h. The arrangement may be modified so that the ejector and pump are started together. When the vacuum rises to a value determined b a contact k, a holding winding n is de-energized and the circuits of the solenoid g and winding e are broken and the pump b stopped. A switch s opens the circuit of the windings m, n if the supply of cooling water for the pump d fails.

Title: Improvements in or relating to heating filaments for indirectly heated electrodes
IPC: H01J1/22
Filed: 1957-07-18
Abstract: A heating filament suitable for an indirectly heated electrode, e.g. the cathode of a valve, has an insulating coating of aluminium oxide coloured by a relatively small quantity of metallic oxide additive which produces the coloration of the aluminium oxide by diffusion thereinto, the coloration being such as to increase the heat radiating efficiency of said filament compared with a filament having a pure aluminium oxide coating but the proportion of said other metallic oxide relative to the aluminium oxide being insufficient to reduce substantially the insulating efficiency of said coating. Metallic oxides which can produce coloration of aluminium oxide by diffusion thereinto are those which produce coloration in natural or synthetic precious stones of the corundum group, e.g. ruby and sapphire.  The additive may be 0.1 to 2% of an oxide of chromium, titanium or vanadium or 0.01 to 1% of oxide of iron or cobalt.  Thus the filament may be coated with a suspension of aluminium oxide (with a grain size of 1 to 35 microns) in a saturated solution of a chromium salt, e.g. chromium nitrate by spraying or dipping the filament or by spreading the suspension thereover.  The coating is fixed by heating the filament to 1600-1700 DEG C. whereupon the chromium oxide is formed and diffuses into the aluminium oxide crystals to colour them red.
