Patent EP-0219426-A3 (EP)
IPC: C08B13/00
Filed: 1986-10-06
Abstract: A hydroxypropoxyl-containing cellulose ether, e.g. 
hydroxypropyl cellulose and hydroxypropyl methyl cellulose, 
is esterified into an acidic dicarboxylic acid ester useful as a 
enteric coating material of solid medicament forms. The es­
terification reaction of 100 parts by weight of the cellulose 
ether with phthalic or succinic anhydride optionally combined 
with acetic anhydride is performed in 200 to 700 parts by 
weight of acetic acid as a solvent in the presence of 50 to 150 
parts by weight of an alkali metal acetate, e.g. sodium acetate. 
The cellulose ether product is so tough and resistant against 
attack of a simulated gastric juice that the solid medicament 
forms coated therewith are imparted with highly reliable en­
terosolubility.

IPC: H04L12/18
Filed: 1987-07-22
Abstract: In a Local Area Network (LAN) comprising a 
plurality of stations having associated ports where each 
port has a unique address, an arrangement for providing 
selective broadcasting to a subset of the plurality of 
stations is disclosed. A transmitting one of the stations 
designates the subset by specifying two or more receiving 
stations. Thereafter, the transmitting station generates a 
single data message having a single specified address of 
only one member of the subset. A packet switch controller 
defines a mask that identifies which stations are included 
in the subset. The packet switch controller provides the 
appropriate mask to the transmitting station which then 
transmits a data packet comprising a data message, the 
specified address and the appropriate mask to the LAN. Each 
port decodes the transmitted specified address and the mask 
to determine if the transmitted message is intended for its 
associated station as a member of the subset.

Patent EP-0271329-A3 (EP)
IPC: C04B28/14
Filed: 1987-12-09
Abstract: A process is disclosed for the formation of 
hydraulic binders and building elements comprising 
from 70% ettringite and up to 30% calcium silicate 
hydrates. Ettringite is a very strong mineral and 
the product may be at least the equal in terms of 
mechanical properties of Portland cement while 
suffering shrinkage and expansion problems. The 
process comprises mixing powdered source materials of 
reactive CaSO₄, CaO and Al₂O₃ with or without 
SiO₂ and hydrating the intimate mixture at a ratio 
in the range of l part powdered source materials to 
0.35-l part water. Most conveniently, impure source 
materials such as industrial by-products are used as 
they have been found to catalyse the hydration 
reaction. Further if gypsum is a powdered source 
material, in a natural, pure or chemical form, it is 
preferably calcined since such material sets quickly 
and gives early mechanical strength. A clinker of 
calcium sulphoaluminate may be produced for use as a 
powdered source material.

Title: Automatic microprocessor fault recovery system
IPC: G06F11/00
Filed: 1989-03-15
Abstract: Telecommunications equipment used in outdoor environments are 
subjected to harsh electrical conditions. Circuits which utilize 
sequential components, such as microprocessors, can therefore become 
confused due to extraneous power surges which may occur in the harsh 
conditions existing around the equipment. Furthermore, maintenance 
of the equipment has become much more automated, often leaving the 
equipment unattended for extended periods of time. In accordance 
with the invention, a circuit which automatically and reliably 
recognizes the failure conditions in the microprocessor, and 
automatically forces the microprocessor to recover is described.
