Patent GB-392571-A (GB)
Title: Manufacture of new compounds from terpene alcohols and hydroaromatic alcohols
IPC: C07C35/29
Filed: 1931-10-15
Abstract: Addition compounds are manufactured by reacting a monohydric terpene alcohol or monohydric hydroaromatic alcohol (other than a menthol) with orthophosphoric acid.  The reaction may be carried out in the presence of an organic solvent indifferent to orthophosphoric acid, the product being isolated by crystallization or by expelling the solvent.  Examples describe the reaction of orthophosphoric acid with (1) cyclohexanol in the presence of benzene; (2) fenchyl alcohol in the presence of petroleum ether; (3) borneol, in the presence of petrol; (4) terpineol in the presence of petroleum ether.  Homologues of cyclohexanol, e.g. methylcyclohexanol, are also specified as starting materials.  In the case of the borneol compound, one molecule of alcohol combines with each molecule of acid, but in the other cases the products contain three molecules of alcohol p  per molecule of acid.  The products decompose on heating into their constituents, in some cases with dehydration of the alcohol.

Abstract: 898,580. Discharge lamp circuits. GENERAL ELECTRIC CO. Ltd. Sept. 2, 1960 [Aug. 21, 1959], No. 28681/59. Addition to 854,206. Class 38 (4). [Also in Group XL (c)] In an arrangement as disclosed in the parent Specification wherein a discharge lamp 14 is supplied from a D.C. source through a transistor oscillator, the oscillator is modified for use on higher D.C. voltages by connecting the collectors and emitters of at least one pair of transistors 1, 2 serially across the D.C. source 3. The mid point of the transistors is connected through the primary winding 9 of a transformer 10 to a voltage divider comprising equal resistors 6, 8 and capacitors 5, 7 also across the D.C. source 3. Positive feedback is provided by secondary windings 19, 20 connected to the transistors through CR circuits 21-24. The discharge current is provided by a secondary winding 11 resonated by a capacitor 12. The transistors 1, 2 conduct alternately in push pull thus causing currents in alternate directions through the winding 9. The transistors operate under class C conditions giving a square-wave output before the lamp strikes and a sinusoidal waveform after. The arrangement is stated to operate reliably in the range of 50 to 40 volts D.C. for the source 3. In another embodiment (Fig. 2, not shown) for operation on 110 volts D.C. each transistor is replaced by two seriesconnected transistors with a CR potential divider connected across each transistor, the centre point of the array being connected through the primary winding 9 to another potential divider in the same manner as shown in Fig. 1. Typical component values and winding details for the transformer are given in the Specification. Specification 856,105 also is referred to.

Abstract: 1286148 Apparatus for wrapping coils BRITISH STEEL CORP 1 June 1970 [6 June 1969] 28728/69 Heading B8C Apparatus for wrapping a coil 32 comprises a wheeled carriage supporting a roll of wrapping material 31 and having means 6 for supporting the coil 32 on a bed plate 28, whereby, when the wrapping material 31 is attached to the coil 32 and the carriage 1 is moved along the bed plate 28, the coil 32 is rolled along the bed plate 32 to cause the wrapping material 31 to be wrapped therearound. The coil-support means 6 comprise mandrel housings 18 slidably supported in elongate openings 5 in side panels 2 of the carriage 1, so as to be adjustable for various coil-diameters. Each housing 18 slidably supports a rod 19 carrying a roller 20 which engages the inner periphery of the coil 32. The side panels 2 also have elongate openings 7 which slidably receive carriages 21 slidably carrying rods 23 which support folding heads 22. After wrapping, a bar 16 carried by slides 15 is lowered to clamp the wrapping material to the coil, the wrapping material is severed and taped or bonded to the coil, and the bar 16 then retracted. The folding heads 22 are then moved to a position adjacent the coil so that further movement of the carriage 1 causes wrapping material which protrudes from the sides of the coil to be folded against the faces of the coil by the heads 22. The rods 19 are then retracted, excess wrapping material is tucked into the coil, and the rods 19 reinserted. A metal sheet 33 is then placed on the bed plate 28 and the carriage moved to roll the coil on to the rear end of this sheet, which is then taped or bonded to the wrapped coil. Further movement of the carriage 1 then causes the sheet 33 to be rolled about the wrapped coil. During this movement guillotines 25 snip the protruding metal sheet to enable this to be folded on to the faces of the coil by the heads 22, the guillotines 25 being carried on rods 26 slidably supported in carriages 24 received in elongate openings in the side panels 2. The clamping bar 16 is then lowered, the sheet 33 is taped or bonded to the wrapped coil, the clamping bar 16 and the rods 19, 23, 26 retracted, and the carriage 1 moved to expose the packaged coil. Covers are then applied to the faces of the coil and banding applied to complete the wrapping.

Abstract: 390,746. Weft-feeler arrangements for looms. POLLAK, J. E., 20, Holborn, London.- (Eta blissements Benninger Soc. Anon.; Uzwil, Switzerland.) Oct. 14, 1932, No. 28733. [Class 142 (iii).] A weft - feeler arrangement adapted to reduce the pressure of the feelers on the yarn is arranged on a stationary part of a two-shuttle loom on the change-box side, and is provided with two feelers each adapted to make operative connection with a knife having a constant throw, and one of which makes a contact through a hole in the swell with the weft of the inoperative shuttle. The feelers 14, 15 either pass through holes in the swells 4, 5 or engage a plate 12, 13 on the shuttle-box, are guided in holes in a casing 16, and are pivoted to levers 18, 19 on the casing. The levers have projecting parts 32 each in the path of a knife 30 operated by a cam 28. When the lay moves to the back centre, the plate 12 or 13 moves one of the feelers so that its projection clears the knife. If there is sufficient weft on the bobbin, the other feeler will also be operated. If the weft is exhausted, the projection 32 controlled by the feeler of the inoperative shuttle is engaged by the knife 30 whereby the lever 18, Fig. 3, and the casing are moved to the left against the action of a spring connection with a plate carried by a lever 20. When the projection 32 has been moved a small distance, it engages a counter-stop 31 on the lever 20 which is then moved against the action of a spring 25 and without any further pressure on the pivot 18<1> of the lever 18. On the return movement of the lever 20, after producing the change of shuttle or bobbin, or stopping the loom, the counter stop 31 remains in contact with the projection 32 till shortly before the lever 20 engages a stop 26, when the casing 16 is moved by a weak spring 24 to the right over the plate carried by the lever 20.

IPC: C01B33/46
Filed: 1938-10-04
Abstract: 519,808. Catalytic agents. HOUDRY PROCESS CORPORATION. Oct. 4, 1938, Nos. 28782 and 28783. Convention dates, Oct. 23, and Nov. 17, 1937. [Class 1 (i)] Contact masses particularly for treating hydrocarbons are obtained by forming a zeolite from solutions which contain an alkali metal cation and a controlled amount of an anion of a non-amphoteric element, and treating the zeolite with a solution containing a volatile or unstable cation until the alkali metal is reduced to 1 per cent. or less. This solution is preferably an ammonium or amino salt such as ammonium chloride, sulphate, nitrate, and carbonate and methyl and ethyl amino hydrochlorides. The non-amphoteric anion may form part of the reactants producing the zeolite, or it may be separately added to them during mixing, or after mixing to act as a coagulant. In the last two cases it may contain a volatile cation and may be one of the above-mentioned ammonium salts. The pH value at the time of precipitation should be below 11. After the treatment with the base-exchanging solution the body may be heated to drive off the volatile anion leaving only the nuclear substance. Active metallic oxides may be introduced by base exchange. Specification 478,216 is referred to.
