Title: Improvements in formwork elements
IPC: E04G17/06
Filed: 1989-06-26
Abstract: An assembly of water stop (10) and threaded tie bar 
(12) for use in the casting of concrete to provide 
concrete walls subject to water pressure is provided 
wherein the water stop (10) comprises a moulded 
elastomeric annular flange portion (14) of greater 
overall diameter than an integral boss (16). The water 
stop (10) may be initially slid onto the tie bar (12) in

axially of the tie bar under the action of water pressure 
induced axial forces acting on that face (20) of the 
flange portion (14) in a direction opposite to the 
direction of thread advancement. Water pressure induced 
axial forces acting on the face (20) cause compression 
and radially inward contraction of the boss (16) sealing 
and locking the water stop to the tie bar thereby 
preventing water penetration past the water stop.

Patent EP-0393314-A3 (EP)
Title: High data rate asynchronous communication method and apparatus
IPC: H04L1/18
Filed: 1990-02-07
Abstract: A method of communicating between a primary station 10 
and a secondary station 20 wherein variable sized 
packets of information are transferred asynchronously 
(or in start/stop mode) between the primary station 
and the secondary station. A communication control 
(e.g., "BREAK" in the preferred embodiment) indicates 
the end of each packet. To permit the high speed 
transfer of data, the secondary station receives a 
high-speed clocking signal externally, from the 
primary in the preferred embodiment. The primary 
station generates and transmits a sequence number in 
connection with each packet, and the secondary 
responds to each packet with a status, but without 
generating a sequence number of its own or trans­
mitting a sequence number. The primary station 
responds to the lack of a response from the secondary 
station by resending a transmission, while the 
secondary station responds to a duplicate trans­
mission by ignoring the second transmission, and 
responds by resending the status from the previous 
transmission (which may not be the current status). 
This method using a minimum of overhead insures that 
the secondary station only proceeds after it has 
successfully transmitted its last status to the 
primary, thus guaranteeing that dynamically changing 
status will not be lost.
