Title: Process for the hydrogenation of carbon monoxide
IPC: C07C1/04
Filed: 1956-10-15
Abstract: In the catalytic hydrogenation of carbon monoxide at pressures greater than three atmospheres and preferably greater than 8 atmospheres the catalyst is extracted, without shutting of the synthesis or recycle gas, with an oil which has been synthesised by the hydrogenation of carbon monoxide and which has been treated before use with an alkaline material.  The process can be applied to any type of catalyst whether fixed bed, fluidised or as a slurry as described in Specification 845,559.  The alkaline material may be an oxide, hydroxide, carbonate or bicarbonate of an alkali or alkaline earth metal or ammonia.  The contacting with the oil may be by mixing or counter-current contact using an aqueous solution or, preferably, by trickling the oil over the solid.  The oil need not be totally neutralised but preferably the amount of alkali is 10-50 times the stoichiometric amount for neutralisation.  The neutralisation number, i.e. milligrams potassium hydroxide required to neutralise 1 gram of oil is preferably reduced to 3-20.

Abstract: 539,108. 17-Substituted androstanolones. SOC. OF CHEMICAL INDUSTRY IN BASLE Dec. 5, 1939, No. 31513. - Convention date, Dec. 10, 1938. Sample furnished. [Class 2 (iii)] Saturated or unsaturated androstanolones containing a substituent in the 17-position are prepared by the reaction of an organo-metallic compound on a 3-endate or a 3-acetal of a saturated or an unsaturated androstandione, with the exception of the reaction of 3-enolates of saturated or unsaturated androstandiones with metal salts of acetylene or of monosubstituted acetylenes as described in Specification 516,444. If desired the product may be saponified. Parent materials mentioned include the 3-enol ethers such as the 3-ethyl-, or 3-methyl-enol ethers, and the 3-acetals such as the 3-glycollates. Organo-metallic compounds mentioned include the alkali salts or the heavy metal salts of acetylene or a mono-substitution product thereof, an aryl-, aralkyl-, or alkylalkali compound, a magnesium organic .compound, such as a methyl-, ethyl-, aralkyl-, or aryl-magnesium halide, an acetylene magnesium halide, and a zinc alkyl compound. In an example, a toluene solution of androstandione-3- mono enol ether is added to an ether solution of methyl magnesium bromide and the reaction mixture worked up in the usual manner to give 17-methyl testosterone. Similarly, 17-methyldihydrotestosterone may be obtained from the 3-glycol acetal of androstandione. The mother liquors yield a small amount of the alcohol epimeric in the 17-position. A sample has been furnished under Sect. 2(5) of 17-ethinyl-testosterone prepared by the addition of acetylene mono-magnesium bromide to androstenedione-3-glycolacetal in ether solution or the working up of the product by the addition of dilute acid. The Specification as open to inspection under Sec. 91 includes also the use as parent materials of enol esters of saturated and unsaturated androstanediones, and also the reaction of metal salts of acetylenes or mono-substituted acetylenes with the 3-endates of saturated or unsaturated androstanediones. An example is also included in which a benzene solution of androstanedione 3-mono-enol-ethyl ether is added to a solution of potassium in amylene hydrate and acetylene passed in to give on working up the product 17-ethinyl testosterone. This subject-matter does not appear in the Specification as accepted.

Filed: 1945-11-23
Abstract: 604,067. Thermal switches. COLE, Ltd., E. K., and MOORE, F. J. Nov. 23, 1945, No. 31565. [Class 38 (v)] A snap-action, thermal-delay, switch with ambient temperature compensation, for protecting transmitter valves and starting discharge tubes, comprises a dished bimetal disc 5 carrying a contact 3, which snaps down from the co-operating contact 2 when the heater coil 4 is energized. The contact 2 is carried on a bimetal spring 1, arranged so that it tends to move away from the disc 5, with increase in ambient temperature, to vary the pressure it exerts on the disc and so maintain a constant delay period. The contact on the disc may alternatively engage a contact 8 in the base when operated, Fig. 1 (not shown). In addition a bimetal strip 11 may be arranged above the heater so that it releases a blade-spring 10, which lifts the arm 1, and holds the contacts open, until reset by button 13, if the lamp fails to start.

Abstract: 1,197,201. Photographic type-composing apparatus. VARITYPER CORP. 10 July, 1967 [8 July, 1966], No. 31731/67. Heading B6W. The invention provides, for a photo-composing machine of the sort described in U.K. Specification 981,657 (Division B6W), a device for advancing a light sensitive web stepwise through an exposure station of the machine in increments appropriate to selected fount characters the device having a drive means comprising a primary drive 102 reciprocable through a fixed amplitude, a drive train including a reciprocable slide 76 carrying a probe 91, a yieldable link in the drive train between the primary drive and the slide, the link moving the slide in a given direction when the primary drive is actuated; rotatably mounted drive limiting means 22, defining a series of circumferentially arranged stops (slots, in the embodiment shown) one stop being provided for each fount character, any one of these stops being positionable, by rotation of the drive limiting means 22, in the path of the probe 91 to thereby limit movement of the probe when the primary drive is actuated; continued movement of the primary drive after the probe encounters a stop being accommodated by the yieldable link and the movement of the probe being transmitted to the web advancing means for providing web advancing movement thereof. Depression of button 101, Fig. 3, and hence the swingable primary drive rod 102 also illuminates the exposure light. The movement of slide 76 is translated into rotation of a sprocket 27 (which advances the web) through lever assemblies 52 and 54 mounted on rod 30. The slide engages one of two pins 72, 73 fixed to levers 52 and 54 respectively, or passes between the pins, depending upon the position of carriage 86, Fig. 7, transmission gearing being arranged such that engagement of slide 76 with pin 73 produces twice the degree of sprocket rotation produced by engagement with pin 72. For interword spacing a simultaneous depression and rotation of rod 102 produces advancement of slide 77 to engage pin 72. Slide 77 is free of control by the character spacing disc 22, but its movement may be controlled by a cam for justification purposes.

Title: Analogue-to-digital converter
Inventor: PRICE JOHN CLIFFORD
IPC: H03M1/00
Filed: 1965-07-26
Abstract: 1,086,908. Selective signalling. STANDARD TELEPHONES & CABLES Ltd. July 26, 1965, No. 31805/65. Heading G4H. An electric analogue-to-digital converter comprises a series of interconnected bi-stable elements, each of which is connected to a constant current source and associated switching means arranged to connect it to a common impedance, means for applying to the common impedance an amplitude sample with a damped oscillation imposed upon it, the switching means being responsive to a predetermined voltage across the common impedance. In the form of Fig. 2A the unknown impedance signal I8 has a value increasing from zero. This current passes through R7 to 4V + line. There are two transistors, one for each output digit, connected in pairs T1, T2 and T3, T4. Initially T1 and T3 conduct so that the constant currents I1 and I2 are drawn through resistors R1 and R3. As Is increases the voltage V1 at the resistor R7 increases and voltage V2 decreases (Fig. 2B). When it equals the bias voltage B1 on transistor T1, this trigger switches to draw the current II through resistor R7. This causes V1 to decrease and V2 to increase, but with a further increase of Is it will come to equal the bias B3 on T3 so that this transistor pair switches, drawing current 12 (twice II) through the resistor R7. The transistor pair T 1, T2 then relapses until as Is increases further it sets again so that both II and 12 are drawn from resistor R7 to balanee Is. Instead of using a rising current, the oscillating signal is imposed upon the unknown sample. This overcomes the backlash of the individual stages and causes the bistables to set in their order of weight, the largest first. A four-digit system is described.

Title: Dyestuff bleaching preparation for the photographic silver dyestuff bleaching process
IPC: G03C7/28
Filed: 1969-06-24
Abstract: 1,255,857. Silver dye-bleaching preparation. CIBA-GEIGY A.G. June 24, 1969 [June 25, 1968], No.31834/69. Heading G2C. A dye-bleaching preparation for the photographic silver dye-bleach process contains an acid, a water-soluble iodide and optionally a dye-bleaching catalyst, wherein a reductone is also present. The reductone may be an aci-reductone which may be a cyclic or acyclic compound possessing a 3-carbonyl-endiol-(1, 2) group. The reductone should have a normal potential reductone/dehydroreductone which is more negative than the normal potential iodine/iodide. The preparation may contain reductic acid, α, #-dihydroxy-acrolein, ascorbic acid, isoascorbic acid, 3-hydroxy-5- phenyl-tetronic acid, 3-hydroxy-5-phenyl-tetronimide or 5-α-chlorophenyl-3-hydroxy-tetronimide as the reductone. The acid may be a strong acid or may be acetic or citric acid. The water-soluble iodide may be hydriodic acid, ammonium iodide, sodium iodide, or potassium iodide. The dyebleaching catalyst may be pyrazine, quinoxaline or phenazine. The preparation may be in the form of a dyestuff bleaching bath or in the form of a gel. The preparation may be introduced into an unexposed colour photographic silver halide material by, e. g. the application of protective layers or encapsulation of the active components so that the dye-bleaching action can only develop on processing the photographic material. These preparations are apparently stable and do not dissolve silver salts out of the materials, which would after their activity, and may be regenerated in extended operation.

Title: Improvements in or relating to arc lamps
IPC: H05B31/00
Filed: 1933-11-17
Abstract: 405,597. Arc lamps. ZEISS IKON AKT.-GES., 72, Schandauerstrasse, SCHERING, H., 61, Villacherstrasse, and GNAUCK, W., 24, Marsdorferstrasse, all in Dresden, Germany. Nov. 17, 1933, No. 32112. [Class 39 (i).] A carbon arc lamp with continuous automatic regulation and means for independent hand adjustment of the carbons when the regulating mechanism is disconnected, is such that spindles moving the positive and negative carbons respectively are coupled together by the same movement which couples the automatic regulating mechanism to them. In the example shown in Fig. 1, the shaft 1 carries a fixed spindle 3 having a screw gear on the outside which engages with a screw gear 4 driving a rack 5 carrying the negative carbon, and a loose spindle 11, threaded on the outside, engaging a threaded collar 10 carrying the positive carbon. The hand adjustment of the carbons is made by the knobs 2 and 12. When the handle 14 is thrown over, an axial movement of the shaft is produced so that the clutch surfaces 17, 18 are brought together, and the coupling part 15 engages the coupling part 16 which is driven by the motor as shown in Fig. 2. At the same time the switch 19 carried by the handle 14 closes the contacts and starts the motor. The regulating mechanism shown in Fig. 2 comprises an electric motor driving the chain of worms 26, 28, 30 and worm wheels 27, 29, 31, and a shaft 32 on which the worm wheel 31 and the toothed wheel 36 are rotatably mounted. The worm wheel 31 is geared to the toothed wheel 36 by the toothed wheel 33 and two other toothed wheels (not shown). The coupling member 37 is movable axially but not rotatably on the shaft 32 and may be shifted to engage with either of the members 30 or 36, thus giving two gear ratios to enable both high power and ordinary carbons to be used without alteration of the mechanism.

Title: Dithiophosphoric esters suitable for use as lubricating oil additives
IPC: C07F9/165
Filed: 1960-09-20
Abstract: The invention comprises mixed neutral esters of dithiophosphoric acid having the formula: <FORM:0958378/C2/1> wherein R1 is alkyl, R11 is alkaryl and R111 is a cycloaliphatic radical of the terpene type. They may be obtained by preparing, in a first stage, an alkyl alkaryl dithiophosphoric acid and then heating the latter with an excess of an unsaturated monocyclic or bicyclic terpene capable of providing the radical R111.  The alkyl alkaryl dithiophosphoric acid may be prepared either by heating two mols of an alkanol and two mols of an alkylphenol with one mol of phosphorus pentasulphide in the presence of a suitable solvent, e.g. toluene, and in an inert atmosphere, e.g. of nitrogen, or by heating four mols of an alkanol with one mol of phosphorus pentasulphide to form the corresponding dialkyldithiophosphoric acid and then heating the latter with two mols of an alkylphenol so as to effect transesterification and elimination of the appropriate amount of alcohol by distillation. The first type of reaction to form the alkyl alkaryl dithiophosphoric acid may be carried out in one stage at 112-115 DEG C. but is preferably carried out in two stages, the first stage being effected at between 80 DEG  and 95 DEG C. and the second stage at between 112 DEG  and 115 DEG C., both stages being carried out in a solvent and in an inert atmosphere, e.g. of nitrogen.  In the second type of reaction to form the alkyl alkaryl dithiophosphoric acid the transesterification step may suitably be effected at 150 DEG C. until the required stoichiometric amount of alkanol is distilled out. The reaction with the terpene is carried out with an excess of the terpene which may vary from 5 to 40% of the stoichiometric amount and after mixing the reactants at 35-40 DEG C. the mixture is heated to 110-220 DEG C. for 1 to 5 hours according to the reactants and finally freed of excess terpene by vacuum distillation. The radical R1 may be a primary, secondary or tertiary alkyl radical preferably containing 2-12 carbon atoms.  The aryl radical in the R11 radical is preferably a benzene radical and the alkyl substituent may be primary, secondary or tertiary and preferably contains 2 to 12 carbon atoms.  The terpenes used in the reaction are preferably bicyclic terpenes, e.g. the isomeric pinenes, the carenes and mixtures of natural origin which contain such terpenes, e.g. various essences of turpentine.  Examples are given for the production of (1) 2-ethylhexyl-ethylphenyl-bornyl dithiophosphate (derived from Portugese terpentine essence) and (2) a product obtained by heating isopropyl-octylphenyl-dithiophosphate and essence of Greek turpentine. Other specified alkyl alkaryl dithiophosphoric acids which may be used for reaction with a terpene are n-butyl-nonylphenyl-and 1,3-dimethylbutyl-nonylphenyl dithiophosphoric acids.  The products are useful as additives for lubricating oils.
