Title: Improvements in light sensitive colour photographic materials
IPC: G03C7/392
Filed: 1954-06-02
Abstract: 2-Caprylylhydroquinone is prepared by passing boron trifluoride gas into a slurry of hydroquinone, n-caprylic acid and tetrachloroethane. The product is reduced in acetic acid solution by hydrogen under pressure and in the presence of palladium on charcoal catalyst to give 2-n-octylhydroquinone.  A second caprylyl group may be introduced in a similar manner to give 2 - caprylyl - 5 - n - octylhydroquinone and this may be similarly reduced to give 2:5-di-n-octylhydroquinone.  Similarly, 2 - n - dodecylhydroquinone is treated with lauric acid and boron trifluoride to give 2-n-dodecyl-5-laurylhydroquinone and this is then reduced with hydrogen to give 2:5-di-n-dodecylhydroquinone. 2-Caprylyl-4-methoxyphenol is prepared by passing boron trifluoride into a mixture of p-methoxyphenol and caprylic acid. Reduction as above with hydrogen and palladium on charcoal catalyst yields 4-methoxy-2-n-octylphenol.  Introduction of a second caprylyl group in similar manner gives 2-caprylyl-4-methoxy-6-n-octylphenol and reduction gives 2:6-di-n-octyl-4-methoxyphenol.  2:6 - Di - n - octylhydroquinone is prepared by refluxing 2:6-di-n-octyl-4-methoxyphenol in glacial acetic acid with hydrobromic acid.  It may also be prepared by reducing 2:6-di-n-octylquinone with zinc dust in acetic acid. 2:6-Di-n-octylquinone is prepared by oxidizing an aqueous acetone solution of 2:6-di-n-octyl-4-aminophenol with aqueous sodium dichromate.  2:6 - Di - n - octyl - 4 - aminophenol is prepared by reducing the nitro compound using Raney nickel catalyst.  2:6 - Di - n - octyl - 4 - nitrophenol is prepared by refluxing a mixture of 10-nonadecanone, sodium nitromalonaldehyde and potassium hydroxide in aqueous ethyl alcohol.

Title: Method and Apparatus for Carrying Out Chemical, Electrochemical and Exchange Reactions
IPC: H01M8/0662
Filed: 1967-04-10
Abstract: 1,183,356. Chemical contact apparatus; contacting gases with liquids. SIEMENS A.G. and VARTA A.G. 10 April, 1967 [16 April, 1966], No. 16373/67. Headings B1F and D1R. [Also in Division C2] A chemical or electrochemical reaction or mass transfer is effected between incompletely miscible phases of different wetting properties or between substances dissolved therein by contacting the phases in the pores of a porous reaction body possessing a system of pores of various sizes, the more readily wetting phase being introduced into the porous body at a pressure lower than the other phase whereby a part at least of the smaller pores of the body is filled with the more readily wetting phase and a part at least of the larger pores is filled with the other phase. The less wetting phase may be a gas and the other phase a liquid, or both phases may be liquid. In apparatus for effecting this process, one zone of the porous reaction is disposed between porous covering layers in which the pores are on average smaller in size than those of the porous reaction body, the remaining surface area between the covering layers being covered with an impermeable layer. For catalytic reactions, the porous reaction body may consist of catalyst, or the catalyst may be embedded in the body or in the walls of the pores. In Example 1, an H 2 /CO 2  mixture is scrubbed with 8-normal diethanolamine solution to remove CO 2  in the apparatus of Fig. 2. The diethanolamine solution circulates around the apparatus absorbing the CO 2  in porous reaction body 22 and releasing it to a stream of air in porous reaction body 12. H 2 /CO 2  mixture enters at 24 and the scrubbed mixture leaves at 26, while air enters at 8 and leaves together with entrained CO 2  at 14. Porous bodies 12 and 22 and layers 13 and 23 of finer porosity are of nickel. In example 2, the countercurrent extraction of bromine from aqueous solution with chloroform using the apparatus of Fig. 1 (not shown).

Title: Improvements in or relating to fabrics for the production of collars and analogous articles
IPC: D06M17/00
Filed: 1941-12-22
Abstract: 556,519. Laminated fabrics with skewed wefts. WALL, C. L. Dec, 22, 1941, Nos. 16479/41 and 6085/42. [Classes 42 (i) and 140] A flexible laminated fabric for making-up into waterproof sheets or covers or for the manufacture of semi-stiff collars is produced by securing together by adhesive two layers of fabric in which the weft is set in weaving or on a stenter &c. to make plus and minus angles respectively (e.g. 45 degrees) with the warp, the warps being parallel in the two layers. In a modification a third layer having the weft at right angles to the warp is interposed betwen the other two. The twist of the fibre in the skewed weft may be such that on the face of the cloth the fibre is parallel to the warp. Specification 218,911, [Class 140], is referred to.
Patent GB-797778-A (GB)
Title: Connector and valve assembly for central suction plants
IPC: A47L5/38
Filed: 1956-05-29
Abstract: 797,778. Valves. HALLSTRON, O. H. May 29, 1956, No. 16560/56. Class 135. [Also in Group XXVIII] Each connector 4, Fig. 1, which opens at one end into a central suction duct, not shown, consists of a tapering socket 5 surrounded by a flanged collar on which is hinged a lid 1 embodying a freely mounted insert 6 of either flexible material, such as rubber, or metal; the insert is retained in the lid by an annular ring 7, a number of circumferentially located parts, springs or wires (not shown). Sealing of the socket 5 is effected by suction drawing the insert on to the end thereof. The insert may be suspended by a pair of diametrically disposed pivots 9 mounted in slots 10 in the lid 1, such a suspension facilitating a tilting as well as an axial movement of the insert. Upon removing the suction hose from the socket 5 the lid assembly falls by gravity and the insert seals the socket. A protrusion 11 on the lid interior holds the insert 6 against the socket mouth so that even weak suction effects a satisfactory seal between those parts. The suction hose may engage a larger area socket 4b, and if the socket 5 is removed or reduced in length the insert 6 is provided with a sealing lip 6a. In a modification, the lid is positioned flush with a floor surface and in order to relieve pressure on the insert in the event of the lid being trodden-on, the lid is formed with lips which rest on an annular gasket in the socket flange. The lid hinge is mounted in a ring adjustably fitted in the socket flange which latter may have lugs to enable it to be secured to the floor; the lid is hinged so that it always tends to close. In another modification, the socket is inserted into the elbow and held therein by screws to enable the connector to be vertically mounted on a wall, the elbow and socket flanges being on opposite sides of the wall; the other end of the elbow is inserted into a vertical pipe and secured thereto by a stop screw.

Title: Improvements in the treatment of aluminium sulphate-containing minerals and salts
IPC: C01F7/04
Filed: 1933-06-09
Abstract: Aluminium sulphate-containing materials in admixture with alkali chlorides, nitrates or carbonates are roasted in the presence or not of water vapour, e.g. at 600 DEG  C., and the solid product, admixed with alkali sulphates or carbonates or both, alkaline earth oxides or carbonates, and carbon, is roasted. Alkali aluminate is leached from the melt.  In a modification, the aluminium sulphate-containing material, previously calcined or not, is mixed with alkali sulphates or carbonates, alkaline earth carbonates or oxides, and carbon and roasted, e.g. at 1000 DEG  C. The melt is leached.  During the roasting, hydrochloric, nitric or carbonic acid and some sulphur dioxide are evolved.  The alkali aluminate solution obtained is purified, preferably by oxidation with air, and alumina precipitated therefrom by the Bayer process, or by treatment with carbon dioxide. In the latter case, alkali carbonate for reuse may be obtained from the solution by evaporation, but preferably the solution is treated with alkaline earth oxide or hydroxide.  The resulting caustic alkali solution may be used at its boiling point to decompose further aluminium sulphate materials.  Alumina is deposited from the solution by the Bayer process or by treatment with carbon dioxide.  When, for example, alunite has been calcined with potassium chloride, &c., the solution at this stage may contain potassium carbonate and sulphate. It may be evaporated to produce a mixture of these salts for reuse in the roasting operation, or treated with lime sufficient to precipitate only the carbonate.  The liquid is concentrated, and potassium sulphate separate by crystallization. The caustic lye obtained may be used for treatment of fresh material.  When impure aluminium sulphate material is employed, it is previously purified by dissolution, the solution after removal of iron and other impurities, being evaporated to dryness or semidryness.

Title: Improvements in and relating to variable-speed gearing
IPC: F16D31/06
Filed: 1936-06-15
Abstract: 478,643. Hydraulic transmission of power. BUCKLE, J. A. June 15, 1936, No. 16631. [Class 69 (ii)] In a piston-and-cylinder hydraulic clutch, a single control valve is provided, which is actuated automatically in accordance with the speed of the driving shaft in such manner that as the speed of the driving shaft increases the valve moves from its open position towards its closed position, and a manually adjustable member is also provided which can be set to limit the automatic closing movement of the valve and which can also be operated at any time to move the valve towards its open position thus over-riding the automatic adjustment. The driving shaft b, Fig. 2, is provided with a flywheel a, connected to a hollow shaft c carrying radially disposed cylinders d, each containing a piston e having a gudgeon pin f the ends of which project through slots g in the cylinder wall and carry arcuate blocks h, preferably mounted on ball or roller bearings and engaging eccentrically disposed circular grooves i in the inner faces of the driven casing m, n. Said casing contains oil, being provided with a filler 21 ; the pistons are cored out and carry disc non-return valves e<1> held to the piston by springs e<2>, so that on the outstroke of the pistons, oil can pass from the casing through the valves to replenish the cylinders. The latter intercommunicate through ducts p under the control of an axially-movable valve q which is moved in the closing direction by centrifugal masses 5 pivoted to the flywheel and acting against tension springs 7. The other end of the valve member abuts at s<1> against a member s<2> movable axially by a hand-lever t. The cylinders may be carried by the driven shaft and the casing by the driving shaft, the centrifugal masses being carried thereby and the flywheel dispensed with. The hydraulic clutch is applicable to motor-cars, and is followed by epicyclic reversing gear, Fig. 4, comprising a sun wheel 9 on the driven shaft of the clutch, a ring-gear 13 carried by the output shaft 14, and planet-wheels 12 carried by a member 11 which is movable axially so as to hold the planet carrier stationary to give a geared reverse drive or to connect the planet carrier to the output shaft to give a locked one-to-one forward drive.
Patent GB-1456603-A (GB)
Title: Apparatus for monitoring the state of discharge of a battery
IPC: G01R31/36
Filed: 1974-04-16
Abstract: 1456603 Monitoring battery charge; ELEKTRON FABRIK FUR PHYSICALISCH - TECHNISCHE GERATE KERBER & CO 16 April 1974 [26 April 1973] 16632/74 Heading G1U To measure the state of charge of a battery, the internal resistance of the battery is monitored by comparing the battery terminal voltage on load with the volt-drop across a shunt resistance in series with the battery. The terminal voltage is applied across terminals 11, 12 and thus supplies a current through resistors 24, 26, 25. The shunt resistor (15,) Fig. 1 (not shown) is connected to input terminals 13, 14 of a differential amplifier 16 having variable negative feedback 17. The amplifier output drives current through resistors 22, 26, 25. The voltage at point 23 is thus proportional to the sum of the terminal voltage and the amplifier output, which is itself proportional to the load current. By adjusting the amplifier gain using potentiometer 17, the drop in terminal voltage due to an increase in load current is equalized with the increase in the voltage across the shunt (15). Thus if the internal resistance of the battery remains constant, the voltage at point 23 remains fixed. As the battery discharges to an unsuitable level (about 80% charge) the voltage at 23 changes and this change is detected by positive feedback amplifier 43 whose output is displayed on a meter 55. The voltage at 23 is also monitored by threshold detectors 45, 44 (after filtering 38 and buffer amplification 48, 48a) which operate respectively at 80% discharge and more than 80% discharge. Detector 45 when triggered charges capacitor 67 through resistor 66 until the voltage of Zener diode 68 is exceeded at which point transistors 65, 70 conduct and energize relay 51 which operates an audible alarm. Detector 44 triggers immediately at a level below 80% discharge to energize relay 50 which shuts off the machine driven by the battery.

As shown in Figs. 2 and 3, the plate 2 is grooved at 7 and slotted at 8 and the bar 9, which is secured by a clamp 10 and screw 12 to the edge of the lower panel 11 of the windscreen, is cranked so that its upper end is received in the groove in which it fits to prevent relative turning of the parts, The plate is clamped to the bar at the desired height by a headed screw 14. The antidazzle screen 1 is of any desired shape and material and is hinged to a rod 4 secured in a sleeve 3 formed from the plate 2. In use, the screen 1 is held down by a catch 15 against the action of a spring 5 which tends to raise it to inoperative position against a stop 6, also formed from the plate 2. The cranking of the bar 9 holds the screen 1 away from the upper panel of the windscreen so that the usual wiper may operate. In modifications, the bar 9 extends downwards and may be clamped or hooked to the upper edge of the windscreen, or may be screwed to a cross-bar above the windscreen, or the arm 9, Fig. 8, may extend horizontally and be provided with lugs 18 for securing it to the side of the windscreen and a part 19 for engaging the groove in the plate 2. The screen 1 may be fixed rigidly to the plate 2, or it may be mounted on the bar 9, the plate 2 being secured to the windscreen or other support.
