Title: Improvements in apparatus for controlling discharge of materials from hoppers and like receptacles
IPC: B65D90/58
Filed: 1938-03-29
Abstract: 508,732. Delivering material from hoppers. AMERICAN ENGINEERING CO. March 29, 1938, No. 9592. Convention date, Jan. 5. [Class 78 (i)] Apparatus for attachment to hoppers and like receptacles for controlling the discharge of material, comprises a dust-proof casing within which a gate is reciprocated by rack-and-pinion mechanism arranged in dustprotected recesses at the sides of the hopper exit, the opened gate being movable into an extension of the casing. In the illustrated form, a horizontally-sliding plate valve 21 has upwardly-stepped flanges 22, 23 at each side, the flanges 22 carrying racks on their under surfaces engaged by pinions 30 on a shaft 29 revolved by the hand-operated chain-wheel 31, while the flanges 23 rest on anti-friction rollers 18 which are mounted on stub-shafts 20 in the wall of the valve chamber and lubricated from the exterior of the chamber. The depending flange 15 all round the hopper exit diverts the material from the rollers and the rack-and-pinion mechanism. In a modification, the front edge of the valve projects over a drip channel in the closed position, and one of the fixed flanges 15 while preventing the escape of material, allows the moisture to drain thereunder to the drip channel. In a further modification, the valve moves in an inclined plane, which necessitates braking-means to prevent the opened valve being closed accidentally by gravity. Fig. 5, for example, shows a hand or chain-wheel 131 fitted with two spaced discs 159 which are pressed by springs 161 against the opposite sides of a non-rotating friction disc 158 with sufficient force to prevent the wheel rotating under the gravity pull on the valve. A casing 154 serves to lubricate the bearings 156 and the packing ring 152 prevents escape of lubricant.

Title: Improvements in and relating to electric heating elements and methods of making same
Inventor: BEESON ERIC JOHN GEORGE
IPC: H05B3/00
Filed: 1953-04-09
Abstract: 731,208. Electric heating resistances. BRITISH THOMSON-HOUSTON CO., Ltd. April 1, 1954 [April 9, 1953; Sept. 3, 1963], Nos. 9665/53 and 24412/53. Class 39 (3). [Also in Groups XXII and XL (a)] An electric heating resistance comprises a single strip conductor 1 wound into a single flat volute spiral having the width of the strip parallel to the plane of the spiral. The turns are so closely spaced as to present a substantially unbroken face when energized to red heat. The centre of the spiral may be upwardly or downwardly biased out of the plane of the spiral to allow closer spacing. Metal pins 2 welded to the lower face of the strip 1 are surrounded by insulating beads or sleeves 5 sunk into a mounting base 3, which may comprise a cylindrical refractory block 3 having a glazed concave or convex upper reflector surface 4. The pins may be of equal length and parallel to each other or may be perpendicular to the curved surface 4 ; but when the surface 4 is flat, the pins may be of different lengths to bias the turns out of a flat plane. Alternatively, the pins 2 are inserted in holes drilled in the strip, both the upper and lower ends of the pins, which pass through ceramic insulators 5, being deformed to hold the strip against vibration or expansion. The ceramic insulators 5 may be mounted in a reflector comprising a thin disc of metal spun to a conical or dish-shaped form, the contour of which is shaped to control the degree of diffusion or concentration of the radiation. The metal reflector is of nickel or has a gold surface and a second similar reflector is mounted behind it by spaced metal tubes or straps. The elements may be mounted in an evacuated glass or silica vessel, and may be made by feeding a conducting strip edgewise between the cheeks of a former, said cheeks being spaced apart a distance only slightly greater than the thickness of the strip. The former is rotated to wind the strip into a flat spiral, which is annealed before removal from the former to prevent the strip from unwinding. The turns of the spiral when mounted may be separated from each other only in a direction parallel to the axis of the pins.

Title: Process for producing stable pharmaceutical compositions comprising 3-(hydroxymethyl)-5,5-diphenylhydantoin-disodium phosphate ester
Inventor: HERBRANSON DALE E
IPC: A61K31/16
Filed: 1990-05-24
Abstract: Described is a stable pharmaceutical composition of 3-(hydroxymethyl-5,5-diphenylhydantoin disodium phosphate ester, the prodrug of 5,5-diphenylhydantoin (phenytoin) a commonly used drug for the treatment and management of epilepsy and other types of convulsive states. It has been found that degradation of the prodrug to phenytoin can be controlled by controlling the pH of the composition. Controlling the pH to between 8.3 to 9.4 results in the production of diphenylglycinamide as the primary degradant and minimization of degradation to phenytoin. If the pH is maintained at a lower or higher value, then the degradation pattern changes, with earlier than expected product failure.
