Title: Process for the Manufacture of Tubular and Flat Prostheses from Animal Tissue.
IPC: A61F2/06
Filed: 1967-08-08
Abstract: 1,195,992. Surgical implants. B. BRAUN INTERNATIONAL G.m.b.H. 8 Aug., 1967 [22 Aug., 1966], No. 36378/67. Heading A5R. [Also in Divisions B5 and F2] A prosthetic implant, such as a tube or a patch of tissue, is sterile and comprises three or more layers of animal tissue (e.g. submucosa or serosa from animal intestines) united together, for example, by a collagen paste or by treatment with lactic acid. In particular, a tubular implant is formed 'by covering a tubular former with a tube of the animal tissue, coating the tissue with collagen paste, and then applying a second tube of the animal tissue. The tubular former is of a plastics or glaca material and is smooth surfaced or is formed with a screw-thread so that by temporarily winding a filament over each layer of tissue into the thread the implant is crimped. To facilitate removing the former from within the implant, the former may be heated and stretched so that it can be ramoved from the implant as a filament (Figure 2, not shown). Exemplified therapeutic substances may be added to the collagen paste and the tubular implant may be reinforced by synthetic material or by a metalic spiral and may vary in diameter conically along its length. The animal tissue may be bleached with hydrogen peroxide before being used to form the implant and the implant, or each of its layers in turn, may be hardened with an aldehyde.

Up to four diffractometers are controlled by a programme written on a 5-hole punched tape. Each diffractometer is associated with a separate channel having a tape reader 10 feeding a teleprinter 11, equipped with a reperforating attachment, keyboard and transmitting contacts to a digital computer, (not shown), which are connectable by a switch 13 to an order decoder 12. Timing clock pulses are derived from a fission chamber monitor 14 and fed through an amplifier 15 to a programmecontrolled variable scaler 16 for each channel, controlling a measuring sequence circuit 17. Each channel has a detector 7 feeding a counter chain 18 which is connected to a read-out scaler 19, controlled by the circuit 17, passing its output to the teleprinter 11. Relays 21 are associated with a setting circuit 22 to retroactively control gratings and pick-up heads 23, and, directly, to control ancillary units, (not shown).

Title: A process for obtaining methanol by the hydrolysis of methyl acetate
IPC: C07C29/80
Filed: 1962-09-26
Abstract: Methanol and acetic acid are produced by the hydrolysis of methyl acetate in the presence of water and a non-volatile acid catalyst, wherein an aliphatic or alicyclic hydrocarbon or hydrocarbon mixture boiling at 10 DEG -90 DEG C. is added to the boiling hydrolysis mixture, and a quarternary mixture, of constant boiling point, consisting of methanol, methyl acetate, hydrocarbon, and water is driven off by distillation.  On condensation the mixture separates into an upper layer containing mainly hydrocarbon, and a lower aqueous layer containing most of the methanol which is then distilled off from this layer.  The hydrolysis and distillation of the quaternary mixture are carried out at 0.1 to 3 atm. gauge and the temperature in the distillation column is regulated by the supply of hydrocarbon, so that below the boiling point of the methyl acetate/methanol azeotrope and above the boiling point of the quaternary mixture. The quaternary mixture may be cooled to 0 DEG  to -30 DEG C. and the hydrocarbon layer recycled. Acetic acid which collects at the bottom of the distillation column may be concentrated up to 60% for further use. Specification 826,240, U.S.A. Specifications 2,636,050, 2,671,052, 2,916,512 and German Specification 1,070,165 are referred to.
