Title: Increasing MW of thermoplastic polyesters - esp polytetramethylene terephthalate with flame retardant additive, by heating in solid phase with Gp V metal oxide
IPC: C08K3/22
Filed: 1975-04-21
Abstract: The MW of thermoplastic polyesters is increased by heating an intimate mixt. of the polyester and 0.5-10 wt. % (on polyester) of an oxide of a Gp. Vb metal to a temp.  the m.pt. of the polyester. Method overcomes problems of MW reduction encountered e.g. when making flame-retardant polyesters by melt compounding the polyester with a bromine-contg. flame retardant agent and a synergistic amt. of a Gp. V oxide, esp. Sb2O3, by melt compounding e.g. in an extruder. Lower MW base polyester which has lower viscosity and easier processing characteristics may thus be used.

Title: Making bags from folded thermoplastic film printed on two faces - to reduce unit printing cycles and utilise a simple welding unit
IPC: B31B23/00
Filed: 1980-05-09
Abstract: Printed sacks are made by preprinting the upper and lower faces of a double layer folded or tubular thermoplastic film so that each face carries two rows of printed patterns e.g. (A,A'). The film is then cut along the folded edge(s) (2) continuously and the two separated layers (3,4) of the film are parted. One layer (4) is led to a storage roll while the other layer (3) is itself continuously folded, with the print patterns (I,I') on the opposite external faces, and welded to form the bags. The first layer (4) is subsequently withdrawn from the storage reel, folded, and passed through the same welding unit. Simultaneous preprinting of the upper and lower faces of the double layer film, using a two-faced printer, halves the apparent printing unit cycle from processes which print one face. Only one single-station welding unit is reqd. Bags having two different print patterns can be produced from the same stock of double layer film.

Patent PT-94161-A (PT)
Inventor: HERBRANSON DALE E
IPC: A61K9/06
Filed: 1990-05-25
Abstract: Described is a stable pharmaceutical composition of 3-(hydroxymethyl-5,5-diphenylhydantoin disodium phosphate ester, the prodrug of 5,5-diphenylhydantoin (phenytoin) a commonly used drug for the treatment and management of epilepsy and other types of convulsive states. It has been found that degradation of the prodrug to phenytoin can be controlled by controlling the pH of the composition. Controlling the pH to between 8.3 to 9.4 results in the production of diphenylglycinamide as the primary degradant and minimization of degradation to phenytoin. If the pH is maintained at a lower or higher value, then the degradation pattern changes, with earlier than expected product failure.

Filed: 1991-10-22
Abstract: Frequency components are calculated from the STP-filtered speech signal. The amplitudes of these are combined in a manner such that the resultant values are associated with frequencies which are situated equidistantly on a linear Bark scale. Said components are quantised, possibly after scaling. In the decoder, the components are again distributed over the frequency spectrum. In the coder, the fundamental regularity D is determined with an LTP technique, after which it is transmitted. In the decoder the phases of the reconstructed signal at the spacing D in the past are determined. These phases are combined with the amplitudes already present in the frequency spectrum, after which transformation back to the time domain takes place. Inverse STP filtering is then carried out.
