Title: Microcrystalline 3-(alpha-acetonylbenzyl)-4-hydroxycoumarin(warfarin)compositions thereof and methods of making and utilizing same
IPC: A61K31/37
Filed: 1975-08-13
Abstract: 1513399 Microcrystalline 3 - (α - acetonylbenzyl) - 4 - hydroxy coumarin (warfarin) CARTER-WALLACE Inc 13 Aug 1975 [13 Aug 1974] 33672/75 Heading C2C Microcrystalline warfarin (3 - α - acetonylbenzyl - 4 - hydroxycoumarin), a novel form thereof, may be prepared by buffering warfarin in aqueous solution at a pH of 7 to 10, removing insoluble impurities to obtain a clear aqueous solution of the buffered warfarin, and adjusting the buffer system to bring the solution to a pH in the range of 5 to 7, at which microcrystalline warfarin precipitates. The microcrystalline form of warfarin is a more effective anti-coagulant both in pharmaceutical compositions and in rodenticides.

Title: Compaction and expansion of data
IPC: H03M7/30
Filed: 1972-07-19
Abstract: 1363810 Compacting and expanding data INTERNATIONAL BUSINESS MACHINES CORP 19 July 1972 [22 July 1971] 33677/72 Heading G4A Data consisting of m bytes of data, each having n bits is compared by eliminating bytes consisting of all zeros, compaction information being formed consisting of m bits, each associated with one of the bytes and each bit having a "zero" level when the associated byte consists of all zeros. This enables the compacted data to be expanded by introducing n zero bits into the data at positions corresponding to the zeros in the compaction information. The invention is used in keyword registers of computer controlled documentation systems in which the non-compacted data comprises, for each keyword, a vector of dimension m x n, each dimension being associated with a document number and having a "one" in the associated vector position if the keyword corresponding to the vector is relevant to the document number. As described m = n = 8 and the vector is sectioned into eight hexadecimally coded bytes. To derive the compaction information from the non-compacted information in a register (1, Fig. 3, not shown), the eight bits of each byte are connected to a common OR gate (11-18) so that an eight bit byte is formed in a register (19) having a "one" bit where any of the bits of the associated byte are "one" and a "zero" bit otherwise. This byte is decoded into a signal on one of 256 leads connected to a selection circuit (Fig. 6, not shown). The inputs of a selection circuit are connected by diodes to selected ones of 36 output leads which represent the positions of the eight bytes of the uncompacted data in the compacted data. (The connections are represented in the table of Fig. 7 (not shown) by two digits, the first representing the byte in the uncompacted data and the second its possible position in the compacted data.) The outputs of the selection circuit control AND gates (35-58, Fig. 9, not shown) through which the bytes of the uncompacted data in the first register (1) are transferred to form the compacted data in a second register (2). The data is processed in its uncompacted form but stored in its compacted form.

Abstract: 1352585 Impact wrenches NIPPON PNEUMATIC MFG CO Ltd 19 July 1971 [20 July 1970] 33834/71 Heading B3N A pneumatic impact tool comprises an air inlet port 21 having an air inlet valve 24 operable by a control member 19 and, an air passage 23 communicating with the inlet port 21 via the inlet valve and communicating with the inlet port 64 of an air motor 15 via a time delay valve 32. Control member 19 is operable via control piece 16 to open port 22 and allow air to pass into air passage 23. When control piece is released and member 19 is biased upwardly by spring 25, air passage 23 is connected to atmosphere via ports 27, 28 and 29. The time delay valve 22 is positioned in a chamber 30 and is biased to one end of the chamber by spring 35. Passage 23 is connected to the motor inlet port 64 via ports 38, 39, annular groove 37 and passage 40. In operation port 22 is opened to allow air to enter passage 23 and pass via ports 38, 39 to inlet port 64. Air also passes from passage 23 to air receiver 52 through a port 53. An adjustable needle valve 55 controls the rate of flow of air to the receiver 52. Port 54 connects receiver 52 to one side of valve 32. As pressure builds up the valve is moved against the pressure of spring 35. When the end of valve 32 passes port 52 the pressure acting on the valve rapidly increases to cause the valve to move quickly to an opposite end position in which air flow to the motor is stopped. A changeover valve 66 enables the motor to be driven in either direction.

Title: Improvements in the preparation of paper pulp from hemp and like annual plants
IPC: D21C5/00
Filed: 1957-10-30
Abstract: Paper pulp is made from hemp and like annual plants by cutting the stems thereof into pieces 5-10 mms. in length, submitting them to light leaching in sodium sulphite solution under such conditions of time and temperature that the final yield is between 70 and 85% by weight based on the dry raw material, stirring the leached material in a stream of running water until the undecomposed but loosened chlorophyllian pigments are substantially detached and carried along by the running water, and grinding the washed material.  The leaching step may be effected with a 2-3% sodium sulphite solution at 100-140 DEG C. for 1-3 hours, or 150-160 DEG C. for half an hour.  If desired small quantities of sodium hydroxide, carbonate and dithionite may be added to the sodium sulphite solution.  Alternatively the raw material may be impregnated with a concentrated solution of sodium sulphite, drained and thereafter leached either with a liquid which serves only as a heating medium or with steam.  After grinding, the washed material may be screened so as to separate long fibres from short.  The material to be pulped, either before or after the leaching step, may be submitted to a crushing operation by means of apparatus operated by impact, so that a portion of the long fibres is released, which may be mechanically separated.  Examples are given.

Abstract: 894,442. Flower pots. THOMSON BROS. Ltd., OFFLOW, T. G., and FINCH, R. A. Oct. 4, 1960, No. 33993/60. Class 6(2). In making flower pots of the type comprising one blank of flexible, self-sustaining material rolled to form a frustoconical body portion, and a second blank secured thereto to form the base of the pot, the blank 5 forming the body of the pot is obtained by making curved transverse cuts 6a in a parallelsided web of cardboard, fibre board or other material having a cellulose base and treated to resist deterioration when in contact with moisture. The cuts are defined by arcs of equal radii whose respective centres of curvature are spaced longitudinally along the web, and may therefore be effected by moving the web past a vertically reciprocating, curved cutter. The base of the pot comprises a square-shaped blank having its corners 11 bent upwards for securing to the body portion.
