Title: Method and apparatus for coding messages
IPC: H04L9/18
Filed: 1970-11-26
Abstract: 1318921 Cyphering systems CIBA-GEIGY AG 26 Nov 1970 [29 Nov 1969] 56274/70 Heading H4P A cyphering system comprises a secret code generator providing an encoding programme and a supplementary non-secret generator having parts of its output selected in accordance with the encoding programme which parts modify through a gating means the secret code, the resultant being recorded on, say, 5 or 8 channel punched tape, such tapes being transported physically to a remote destination for decoding. A clear message 1 is mixed with a cypher proprogramme 3 which may be a pseudo-statistical series of long periodicity. Secret generator 5 is controlled by a secret basic code 6 generated at 17 which may be a pseudo-statistical series of long periodicity and a supplementary code generator 8 which may be a random sequence of numbers or letters. The secret code may remain the same for a major number of messages but the supplementary code is freshly generated for each message or part thereof, its function being to prevent different messages or different parts of message from being encoded by the same cypher programme. The resultant is recorded at 9 on a medium 10 which may be alternatively of magnetic type. The de-cyphering arrangement is carried out in a reverse manner to the cyphering. In a modification, Fig. 2 (not shown), a gate (14) passes only a selected portion of the supplementary code which is applied to generator 5 also receiving secret code 17. The supplementary coding information is recorded on medium 10 and is extracted at the remote end.

Abstract: 1359867 Soaking hides and skins ROHM GmbH 3 Dec 1971 [3 Dec 1970] 56309/71 Heading C6C Non-soaked hides, skins, &c. are processed in a soaking liquid having a pH of from 10 to 12 in the presence of a proteolytic enzyme which is active at that pH level to effect soaking without substantial loosening of the hair. Preferably the liquid temperature lies in the range 23‹C to 25‹C or higher and the pH is adjusted by use of caustic soda. Sodium sulphide, sodium carbonate, calcium formate, sodium sulphite or mixtures thereof may be used instead of or in addition to caustic soda, and a polyglycolether may also be added. Suitable enzymes, bacterial and fungal proteinases, may be obtained from cultures of Aspergillus niger, Aspergillus flarus, Penicillium cyanofulvum, Paecilomyces proscinus, Streptomyces sp., Serratia sp., or Bacillus subtilis. After the soaking, liming may be effected in the same liquor. The soaking may be preceded by a dirt removal presoak process which leaves the hides &c. still in a substantially non-soaked condition.

Title: Process for producing Beers of Low Carbohydrate Content
Inventor: GREEN JAMES WILLIAM
IPC: C12C12/02

Abstract: 1,174,618. Beer of low carbohydrate content. A.B.M. INDUSTRIAL PRODUCTS Ltd. Nov.26, 1968 [Dec. 13, 1967], No.56584/67. Heading C6E. A process for the production of beer with a predetermined low residual carbohydrate content involves adding a quantity of the enzyme amyloglucosidase to yeast-fermenting beer wort, allowing fermentation to proceed until only the predetermined amount of residual carbohydrate remains in the beer and then inactivating the enzyme by heat-treatment. Amyloglucosidase produced by a species of the mould Aspergillus is added to the fermenting wort immediately after the bulk of the fermentation yeast has been separated, fermentation proceeds until a predetermined residual carbohydrate concentration not exceeding 1% by weight remains in the beer and the enzyme is then inactivated by heating at 180‹ F. for 15 seconds. The enzyme breaks down glucose oligosaccharides to glucose which is largely fermented.

Patent GB-684381-A (GB)
Abstract: 684,381. Making metal tubes. BUNDY TUBING CO. March 15, 1951, No. 6229/51. Classes 83 (ii) and 83 (iv). [Also in Group XXVIII] In a continuous method of making a metal tube, strip stock is bent into tubular form, the overlapping or abutting edges are tackwelded, brazing metal is applied and the tube passed through a heating zone to braze the seam between the welds. Strip 1 is drawn by feed rolls 31 from a reel 2 through tube-forming rolls 3 and the seam is tack-welded between roller electrodes 10, 11. Brazing metal in the form of a wire 13 is applied to the seam from a reel 14 by a metallizing gun 15 which sprays molten metal on to the seam. The tube then passes through a resistance heating furnace 20 to braze the seam and finally passes through a jacketed cooler 28. Non-oxidizing gas is fed through a pipe 26 to the furnace and to the interior of the tube through a pipe 34 at the forming rolls 3. In modifications of the apparatus a strip of brazing metal is fed directly to the seam from a reel and may be tack-welded by a roller or fusion-welded by an electrode to locate it on the tube before entering the furnace. The strip of brazing metal may alternatively be fed inside the tube at the forming rolls 3 so that in addition to brazing the joint it forms an internal coating to the tube. In a further modification the brazing metal is in powdered form mixed with a mineral oil and is fed as a paste to the seam.

Title: Tyre mould
IPC: B29D30/00
Filed: 1978-07-28
Abstract: A segmental mould which is a part of a tyre-curing or vulcanizing press, comprises an upper sidewall- shaping member (12), a lower sidewall- shaping member (2) and an annular array of radially movable tread-shaping segments (10). A linkage mechanism (18, 20, 21) actuated by a piston (29) which is mounted under the lower sidewall- shaping member, is provided to move the segments radially in respect to the lower sidewall-shaping member. A locking ring (9) attached to the piston and collaborating with shoulders (35) arranged on peripheral sides of the segments prevents the segments from being moved when the mould is closed. The unlocking of the segments is achieved, when the upper sidewall- shaping member is raised, due to the vertical movement of the lower sidewall-shaping member which is caused by springs (7) interposed between the lower sidewall-shaping member and the piston. With the mould closed the upper and lower parts of the press are clamped together by a closure (33). <IMAGE>
