IPC: G01D4/02
Filed: 1938-02-18
Abstract: 491,202. Switches held set and freed mechanically ; momentary - contact switches. LANDIS & GYR AKT.-GES. Feb. 18, 1938, Neo. 5144. Convention date, March 18, 1937. [Class 38 (v)] A measuring device such as an electricity meter 1 sends, as its shaft 2 rotates, a series of current impulses through a switch 9 con. trolled by a secondary source of power 13 and escapement, mechanism. The source of power 13 may be a motor, and tends to rotate through gearing 11 a casing 10 connected by a spring to a shaft 5 carrying arms 3, 4, one of which engages the shaft 2 so as to prevent the shaft 5 rotating till a flat on the shaft 2 frees the arm. The shaft 5 then rotates through 180‹ being then stopped by the other arm 4, which is released in turn when the shaft 2 has turned further. Each 180‹ rotation of the shaft 5 tilts a mercury switch 9 causing the momentary closing of the circuit. In a modification, Fig. 2, the auxiliary source of power is a spring 32 which through a lever 22 and gearing drives the shaft 5. The spring 32 is re-energized by a magnet 24 when it contracts sufficiently for contacts 27, 28 to close.

Title: Manufacture of new derivatives of compounds of the suprarenal cortex hormone series
IPC: A61K38/22
Filed: 1939-02-17
Abstract: 525,307. Cortical hormone saccharides. SOC. OF CHEMICAL INDUSTRY IN BASLE. Feb. 17, 1939, Nos. 5309 and 5310. Convention dates, Feb. 23, 1938, and Jan. 23, 1939. [Class 2 (iii)] Saccharide derivatives of compounds of the cortical hormone series are prepared by treatment of compounds of the above series by methods which are in themselves known for converting hydroxy compounds into saccharide derivatives. The parent materials are characterized by possessing a cyclopentanopolyhydrophenanthrene nucleus with a ketol group in the 17-position. As saccharides there may be used mono-, di-, or tri-saccharides such as glucoses, galactoses and galactose-glucoses. Starting materials specified include #<SP>4</SP>-21-oxypregnene-dione-3 : 20, #<SP>4</SP>-3 : 21-dioxy-pregnene - one-20, #<SP>4</SP>-11 : 21-dioxy-pregnene-dione- 3 : 20, #<SP>4</SP> - 11 - keto - 21 - oxy - pregnene - dione - 3 : 20 #<SP>4</SP> - 17 : 21 - dioxy - pregnene - dione - 3 : 20, #<SP>4</SP> - 11 : 17 : 21 - trioxy - pregnene - dione - 3 : 20, #<SP>4</SP> - 11 - keto - 17 : 21 - dioxy - pregnene - dione - 3 20. The saccharide derivatives may contain one or more saccharide groups together with free or esterified or etherified hydroxyl groups. In examples (1) #<SP>4</SP> - 21 - oxy - pregnene - dione - 3 : 20, acetobromo : glucose and silver oxide are shaken together at room temperature for 60 hours, filtered and crystallized to give a tetra-acetylglucoside. This is hydrolyzed by sodium ethylate in alcohol solution to give #<SP>4</SP>-21- (#-glucosido)-pregnence-dione-3 : 20. The saponification may be conducted with sodium hydroxide. The same product may also be obtained by the reaction of oxy-pregnenedione with penta-acetyl glucose in presence of para-toluene sulphonic acids. Similarly starting from #<SP>4</SP>-3 21-dioxy-pregnene-one- 20 there is obtained a corresponding derivative having two glucose residues in the molecule. (2) #<SP>4</SP>-21-oxy-pregnene-dione-3 : 20, acetobromolactose and mercury acetate are refluxed in benzene solution. The reaction mixture is worked up as in example (1) to give the corresponding hepta-acetyl lactoside which by saponification yields #<SP>4</SP>-21-(#-lactosido)-pregnene-dione-3 : 20. In a similar manner by reaction of oxy-pregnene-dione with acetobromo - (6 - genitobiosido - d - glucose) then is obtained the corresponding trisaccharide.

Title: Improvements in or relating to devices for indicating the presence of two pulses having a preselected time interval between them
IPC: G01S13/10
Filed: 1955-02-24
Abstract: 769,474. Pulse circuits. TELEFONAKTIEBOLAGET L. M. ERICSSON. Feb. 24,1955 [Feb. 26, 1954], No. 5570/55. Class 40(6) A circuit for indicating the presence of two pulses having a predetermined time interval (To) between them comprises a first tuned circuit which is set into oscillation by the first pulse at a frequency fo # 1/2To so that the second pulse coincides with the second half period of the oscillation and an indicating voltage is produced, subsequent cycles of the oscillation are attenuated. Fig. 1 shows a circuit for indicating the presence of a pulse pair 19, 20 (Fig. 2a), in a train of pulse pairs 19, 20; 21, 22 &c. only the pair 19, 20 having a predetermined separation To. The incoming positive-going pulses are applied at 3 to the control-grid of a normally non-conductive pentode tube 1 and since the suppressor-grid is heavily biased the pulse 19 causes heavy screengrid current to flow and tuned circuit 11, 12 to be set into oscillation, diode 13 also conducts and tuned circuit 14, 15 similarly "rings". When pulse 13 terminates, diode 13 is blocked and the potential of the suppressor follows that of the screen grid so that when pulse 20 is applied tube 1 conducts to its anode and an output pulse V8 (Fig. 2c) is produced at the anode. The resonant frequency of circuit 11, 12 is approximately equal to 1 the voltage 2 To across it varying as shown in curve V10 (Fig. 2b) and is some three times greater than that of circuit 14, 15. Thus if the pulse 20 has terminated diode 16 conducts and short-circuits 14, 15, diode 13 also conducts so that circuit 11, 12 is also shorted by diode 16. When a pulse pair such as 21, 22 which has an interval greater than the predetermined spacing To is applied the diodes 13, 16 have time to conduct and short tuned circuits 11, 12; 14, 15 before the second pulse 22 is applied.

Title: Improvements in the manufacture and production of alcohols of high molecular weight
IPC: C07C27/04
Filed: 1934-02-21
Abstract: Aliphatic alcohols of high molecular weight are produced by condensing aldehydes containing at least two carbon atoms by means of organic nitrogen-containing catalysts and simultaneously or subsequently hydrogenating the products in presence of a hydrogenating catalyst.  Suitable aldehydes are acetaldehyde, propionaldehyde, butyraldehyde, stearic aldehyde and crotonaldehyde, and aldehydes containing halogens, and suitable condensing agents are secondary amines such as diethylamine, dibutylamine, piperidine, hydrogenated quinoline compounds such as decahydroquinoline and hydrogenated naphthoquinoline, piperazine, morpholines, and pyrroles, for example, proline and pyrrolidines.  The condensing agents may be activated by oxides and hydroxides of metals of the second and third groups of the periodic system such as calcium strontium, magnesium or aluminium hydroxides or salts having a basic action such as disodium phosphate, sodium carbonate and sodium acetate.  When only organic nitrogen containing condensing agents are employed the alcohols corresponding with the initial aldehydes proponderate as compared with the alcohols of high molecular weight, but when metal oxides are also used the alcohols of high molecular weight preponderate. p  The reaction may be effected in presence of inert solvents such as cyclohexane.  In examples: (1) crotonaldehyde is condensed by means of hydrogenated b -naphthoquinoline and calcium hydroxide, and the product is then hydrogenated with a cobalt catalyst at 150 DEG  C. and 200 atmospheres; the product contains butyl and octyl alcohols and about 55 per cent of monohydric and polyhydric alcohols of high molecular weight; without the use of the calcium oxide only 39 per cent of alcohols of high molecular weight are produced; (2) a mixture of acetaldehyde, decahydroquinoline and a nickel catalyst or silica gel is hydrogenated, yielding a product containing 49 parts ethyl alcohol, 21 parts butyl alcohol and 30 parts of higher alcohols.  The Provisional Specification is not limited to the use of aldehydes containing at least two carbon atoms, and mentions aliphatic hydrocarbons as suitable diluents.

Abstract: 1,168,735. Valves. GENERAL ELECTRIC CO. 7 Feb., 1967 [27 May, 1966], No. 5803/67. Heading F2V. [Also in Divisions F1 and G3] A viscosity compensating valve comprises a spool 60 having a land 74 controlling ports 76 connecting an inlet 70 with an outlet chamber 78. The latter also communicates via filter 86 with passage 88 formed in the spool. A jet of fluid from passage 88 enters passage 92 to generate a total pressure head in chamber 93 which acts on the spool to oppose the action of spring 62. The static pressure is communicated to the chamber at the opposite end of the spool via passages 96, 48 and the spool is thus responsive only to the velocity head which in turn is a function of the viscosity of the fluid The spool thus moves to restrict flow when the viscosity falls and vice versa. As shown, the valve is controlling the supply to a jet tube servo valve 10 (see Division G3).
