Patent GB-1301891-A (GB)
IPC: G05D3/12
Filed: 1970-02-24
Abstract: 1301891 Positioning systems ALLENBRADLEY CO 24 Feb 1970 [5 March 1969] 8695/70 Heading G4H [Also in Division G3] A numerical control system comprises a reference counter, the count in which establishes an absolute reference position, and, for each axis, a command counter storing a programmed end position and a feedback counter which has its count incremented by pulses from a slide transducer. The counters are cycled by a master oscillator and in the indicating system disclosed, the phase difference determined between the cyclic output of the reference counter and that of the appropriate feedback counter. A phase difference signal is derived, through AND logic, as a pulse having a duration representative of the difference which is converted to a clock pulse train which, by NAND-logic, is transformed to binary form and stored. The stored binary count is interrogated through a binary to decimal decoder to provide a visual indication of the actual position of the slide. Additionally, the phase difference between the output of a command counter and a feedback counter is derived to provide an indication of distance to be travelled to the end position and a count of the feedback pulses over a set interval is used to indicate slide velocity.

Title: Method for refining lead, tin and alloys thereof
IPC: C22B13/06
Filed: 1950-04-11
Abstract: A method for the collective removal of impurities, particularly Cu, As, Ni, Fe and bound S, from contaminated Pb or Sn or alloys of these metals is characterized by addition of a quantity of a mixture of alkali hydroxide and S to the molten metal or alloy with energetic stirring and without removal of the dross formed on melting, the quantity of reagent added being less than that stoichiometrically equivalent to the amount of impurities.  A mush is produced on the molten metal bath which consists of impurities and adhering metal. Energetic stirring is continued and a carbonaceous drying agent is added until adhering metal is separated from the mush which is transformed into a dry residue and removed from the bath.  The refining agent, which preferably contains 3 to 5 parts of alkali hydroxide to 1 part of S, may be added in a proportion of 0.1 to 1 per cent by weight of the impure metal or alloy charge.  Examples are given of the refining of Pb-Sn-Sb alloys.

Title: Production of s-acetyl glutathione
Inventor: BRICK ERIC CHARLES
IPC: C07K5/02
Filed: 1954-03-31
Abstract: S-Acetylglutathione is manufactured by treating glutathione with acetic anhydride in acetic acid solution in the presence of perchloric acid.  Advantageously the glutathione is dissolved in a mixture of glacial acetic acid and perchloric acid before adding acetic anhydride, preferably in molar excess, e.g. of about 40-70 per cent.  The perchloric acid may be added in the form of an aqueous solution of not less than about 70 per cent w/w concentration, and preferably in an amount sufficient to give a concentration in the reaction mixture of about 0.5-1.0 molar. The reaction is preferably effected below about 25 DEG  C. with cooling as necessary, and on its completion the excess of acetic anhydride may be decomposed with water and the perchloric acid neutralized (e.g. by adding aniline in about 30 per cent excess over the amount theoretically required) before isolating the product, e.g. by extraction with a liquid such as methanol from which it will crystallize on standing.  Detailed examples are given in which 72 per cent w/w aqueous perchloric acid is used.
