Title: Highly water-soluble hydrated glycosides - produced by freeze-drying aqueous glycoside solutions
Inventor: MCNAUGTHON ANDREW R L
IPC: C07H15/18
Filed: 1973-10-12
Abstract: A highly soluble, unstable form of a hydrated glycoside is produced by (a) dissolving the stable form of a hydrated glycoside in sufficient water, (b) rapidly freezing the aq. soln. to convert the whole compsn. into the solid state, and (c) removing the water by sublimation so as to form a highly soluble, unstable form of the glycoside. The aq. soln. is pref. frozen at below -40 degrees C and the sublimation is pref. carried out at a pressure of below 100mu Hg. Pref. glycosides are mandelonitrile glucosides (esp. amygdalin) and phlorizin. Certain mandelonitrile glycosides (esp. amygdalin) have been used as palliatives in the treatment of certain types of cancer. Other glycosides such as phlorizin have been used experimentally to produce glycosuria in animals, and were also formerly used as antimalarial agents. The process gives the glycosides in highly soluble form. Although unstable, the solns. are stable enough for use as parenteral injection formulations.

Title: Photoelectric scanning of typed or printed characters - derives binary electronic matrix patterns for individual characters
Inventor: ERHARDT RAINER DIPL ING
IPC: G06V10/28
Filed: 1973-11-27

Title: Thin component with thermoplastic front surface - made in mould with shape of finished article e.g. shoe toecap
Inventor: HARDY HENRY
IPC: B29C35/08
Filed: 1973-03-08
Abstract: Mfr. of relatively thin components e.g., a toecap for a shoe with a thermoplastic front surface is carried out by forming a mould with a surface shape corresp. to the shape to be imparted to the front surface. The material of the front surface in contact with the surface of the mould is pressed and heated so that it melts at the front surface and takes on the shape of the mould. While the material is melted, flow of material at the periphery of the mould is controlled, and the material is cooled to render the shape which the material has acquired permanent. Pref. flow of material at the periphery is controlled to form a bead-like edge. Heat may be conducted away from the mould rapidly immediately after heating, and the assembly may be cooled under pressure of deformation to effect bonding.
