Title: Method of improving catalytic actions
IPC: B01J37/34
Filed: 1931-03-16
Abstract: The action of a catalyst is improved by exposing it to an electrical excitation, by means of direct or alternating current.

Title: Improvements in hinged stays more especially those used to extend the hoods of vehicles, baby carriages and the like
IPC: B62B9/14
Filed: 1920-03-19
Abstract: 155,159. Battey, A. P. March 19, 1920. Stays.-In hinged stays of the type wherein two links such as E, G, Fig. 1, are pivoted together as at F and at their free ends are pivoted to the framework of a collapsible hood for a vehicle, baby-carriage &c., the second link G is pivoted at H to a third link J which is pivoted to the frame A at K. This link is provided with a lever and handle L for operating it. The hood is shown fully extended. To lower, the lever L is swung in a clockwise direction, thereby decreasing the effective length of the stay and causing the hood to collapse. In extending the hood, the action of the link J is to give a further extension to the stay beyond its main extension. Modifications involving the use of an eccentric, or of an arrangement involving the use of pins sliding in slots are described. The third link may alternatively be pivoted at F or D. A stop N on the lever arm of the third link engages with a lug M on the link G to prevent the stay-bar from moving past its fully extended position.

Title: Improved manufacture of organo-siloxanes
IPC: C08G77/00
Filed: 1944-05-02
Abstract: Liquid interlinked siloxanes suitable for use as hydraulic, insulating, water-proofing or thermal expansion fluids, or after further polymerization as coating and impregnating agents, are obtained by reacting in presence of a watersoluble alkali at least two organo siloxanes which are soluble in a common solvent and one of which at least is completely dehydrated, i.e. free from hydroxyl groups, the reaction temperature being below that under which decomposition or further polymerization of the siloxanes occurs.  One of the siloxanes may have a structural unit of the formula RR1SiO and another the formula R112SiO, where R and R11 represent alkyl radicals and R1 and aryl radical.  Solvents specified are water, alcohol, dioxane, ether; sodium and potassium or quaternary ammonium hydroxides may be used as alkali.  (1) Equal parts of dimethyl silicone (prepared as described in Specification 572,331 and having a viscosity of 450 centistokes and containing less than 0.2 per cent hydroxyl groups) and phenyl ethyl silicone (300 centistokes) are warmed in presence of one-eighth part by weight of solid sodium hydroxide; a homogeneous liquid is obtained; (2) a mixture of diphenyl silicone, and dimethyl silicone was similarly reacted in presence of potassium hydroxide; (3) bisphenyldimethyl silicyl oxide and bis-trimethyl dilicyl oxide reacted in presence of potassium hydroxide in alcohol to give a single phase.  On standing 24 hours it was distilled after neutralization and washing and the unsymmetrical phenyldimethyl silicyltrimethyl silicyl oxide distilled over; (4) bis-trimethylsilicyl oxide and dimethyl silicone; (5) bis-phenyldimethyl silicyloxide and dimethyl silicone were similarly reacted.  Specification 583,875 also is referred to.

Title: Improvements in and relating to vibro-gyratory finishing machines
Inventor: CUNNINGHAM-SMITH D
IPC: B24B31/073
Filed: 1969-02-15
Abstract: 1,267,971. Finishing. WILLIAM BOULTON LTD. 8 Jan., 1970 [15 Feb., 1969], No. 8324/69. Heading B3D. A method of unloading a charge of workpieces and finishing media from a vibratory finishing mill comprises inserting a dam 32 effective to block the progress of the charge and to cause it to rise up and over the dam to a high level separating zone 20, separating the workpieces from the finishing media in said zone, returning the finishing media to the mill and discharging the workpieces. The mill has a finishing chamber 7 lined with rubber or other material 9 and is supported by springs 6 on a base 5. A sleeve 10 secured to the chamber 7 supports a motor 8 driving adjustable eccentric weights 15, 16 which impart to the chamber a high frequency rotary oscillation about the axis of the chamber together with an upward and downward component. The chamber includes a high level separating zone 20 and washing zone 21 having a perforated floor 23, the separating zone being covered by a perforated screen 25 and the washing zone by a flat plate 26. The floors of the separating zone and washing zone are provided with steps 23a which cause tumbling of the workpieces to assist in removing trapped media. Sprays 33 are mounted in the washing zone and for wet processing liquid may be supplied to the chamber from an arcuate spray pipe 38 connected to a pump 36. The dam 32 can be moved from a position above the chamber, in which it does not impede the movement of the charge around the finishing chamber, by piston and cylinder devices 31 to a position in the chamber in which it causes the charge to climb over the dam into the separating and washing zones. In another embodiment the dam is fixed in position and a further dam is provided to slow the passage of the charge through the finishing chamber. In a further embodiment separation of ferrous workpieces may be effected magnetically.

A pair of wings 13, 14 are adjustably mounted on the rods 12. The wing 14 is provided with projections 15 having openings wider in diameter than the rods 12 and formed with a squared upper end to engage a notch 17 on each rod when it is in an upright position, and carries a transverse anchoring-pin 18 which passes loosely through an elongated opening 20, Fig. 4, in each of two check members 19, arranged parallel to the side walls 8. so that movement of the wing 14 into the displaced position shown in broken lines in Fig. 1 may be effected by raising the wing to disengage the notch 17 and then inclining it to rest on the brackets 10. The wing 13 is adjustable along the rods by means of a transverse lock 23, comprising a spring-actuated member 50 normally inclined and permitting movement of the wing 13 towards the wing 14, but preventing reverse movement unless the member 50 is rendered vertical. The wing 13 has also a pivotal movement limited by a pin moving in an arcuate slot. The check members 19 are provided with inclined top walls 24 to guide the sheets into position, and the sheets are held in place by a central guide-bar engaging a notch in the sheets. the guide-bar being clamped in position by transverse strips 26. The parts 7, 19, 26 and a foot 31 are secured in assembled relation by a bolt 29 and sleeve 30 at each corner..

Patent GB-747808-A (GB)
Title: Improved method for the preparation of hormone materials and hormone materials so produced
IPC: A61K38/35
Filed: 1954-03-23
Abstract: Adrenocorticotropin and oxytocin are recovered from the same batch of pituitary material e.g. hog pituitaries, by extraction with an aqueous acidified acetone solution of pH below 4 e.g. using a strong mineral acid such as hydrochloric acid, and containing 50 to 85 per cent by volume of acetone.  The acetone concentration of the extract is adjusted to between 86 and 95 per cent to precipitate the adrenocorticotropin and the separated supernatent phase is distilled under reduced pressure to remove the bulk of acetone e.g. to a concentration of less than five per cent, thus obtaining a concentrated aqueous solution of oxytocin and vasopressin.  Oxytocin may be separated from vasopressin by extraction e.g. by counter-current contact, with butanol or any isomer thereof, after adjusting the pH to between 2 and 4,5 e.g. by addition of sodium or potassium hydroxide.  The oxytocin may be recovered from the butanol phase by extraction with aqueous acetic acid e.g. 0,25 per cent acetic acid, to yield an acidified aqueous oxytocin solution which may be sterilized by passage through a Seitz filter.  The butanol solution may be prepared for the acetic acid extraction by washing with a suitable buffer e.g. 2M phosphate buffer, until neutral and then drying with a suitable agent e.g. anhydrous sodium sulphate.
