Title: Apparatus for improving a golfer's putting stroke
Inventor: LEWIS JOHN F
IPC: A63B69/36
Filed: 1993-11-22
Abstract: ABSTRACT OF THE INVENTION      A simple, reliable and effective apparatus for assisting a golfer in improving their putting stroke is disclosed.  The apparatus includes a guide attachable to the waist of the golfer and an extension attachable to the putter grip.  The guide includes a narrow slot which is horizontally oriented when the guide is attached to the waist of the golfer.  The extension includes a top end which terminates in a thin, wide guide member which slides in the slot of the guide.  The extension is preferably a longitudinal section of a cylinder which will clip over the putter grip.  The putter grip is preferably covered with the loop portion of a hook and loop fastener. A strip of hook fastener is bonded to the extension so that the hooks engage the loops when the grip of the putter is forced into the bight of the extension.  This provides a strong effective attachment.  The advantage of the apparatus is that it provides a reliable guide which permits the user to relax and learn the motions required for an ideal putting stroke.  The same principle of attachment can also be used to provide an extension for use with a normal length putter in pendulum stroke putting.
Patent CA-2112802-A1 (CA)
Title: Production of pulp by the soda-anthraquinone process (sap) with recovery of the boiling chemicals
Inventor: GORDON OTTO
IPC: D21C11/12
Filed: 1993-04-30
Abstract: A process is proposed for the production of cellulose out of wood and annual plants, in which the digesting liquor contains free caustic soda, eventually sodium salts of alkyl benzenesulfonic acids, of aromatic or aliphatic carboxylic acids.      By addition of anthraquinone or its derivatives to the digesting liquor, the delignification is improved. The limitation of quantities for price reasons is eliminated, because anthraquinone is resistant to wet oxidation and can be reintroduced into the digesting process. The solubility and therefore the effectiveness of anthraquinone is improved by the use of sulfonic acid salts.      For the recovery of the digesting chemicals contained in the black liquor, it is proposed that the solubilized lignin is precipitated with mineral acid or carbon dioxide, that eventually the hemicelluloses are separated by ultrafiltration and the resins by extraction and that the residual organic compounds, except the sulfonates and the carboxylates, are burned in an aqueous phase with air and/or oxygen. The solution of chemicals, containing no more wood decomposition products, can by caustification of the carbonates be re-transformed into caustic soda and after partial crystallization of the aliphatic carboxylates be used for the cycle of pulp production. The sodium acetate isolated by crystallization can by means of membrane electrolysis be split in acetic acid and sodium hydroxide. The caustic soda is reintroduced to the digesting process, the acetic acid is treated separately.

Title: Process to improve the color of sulf(on)ated surfactants without bleach
Inventor: KHAN VAJIH A
IPC: C11D1/28
Filed: 1992-08-28
Abstract: A process for improving dark-colored sulf(on)ated surfactant compositions, and particularly alpha-sulfo fatty acid alkyl ester compositions, without the need for bleaching. The process comprises the steps of (1) forming a solution of a sulf(on)ated surfactant containing dark-colored impurities, in a suitable solvent and (2) separating the dark-colored impurities from the solution. Methyl ester sulfonates and methanol solvent are most preferred.  Treatment of the solution with an adsorbent, preferably activated carbon, enhances separation of the dark impurities. The surfactant is thereafter recovered from the solution by known processes, for example, precipitation of the surfactant and/or evaporation of the solvent. After processing in accordance with the invention, the sulf(on)ated surfactant has improved color, odor, and physical properties.
