Patent EP-0369302-A3 (EP)
Title: Method of and apparatus for producing halftone image
IPC: G03F5/00
Filed: 1989-11-07
Abstract: An image signal (PS) or a screen threshold value (D) is 
converted by a plurality of conversion functions (F i , G i , f i , 
g i ). The number (N ST ) of reference solid pixels, which should 
be exposed to attain a halftone area rate specified by a given 
image signal, is calculated for each quarter block (QB) which is 
a quarter of one unit block for one halftone dot. The numbers 
(N RS ) of virtual solid pixels, which would be exposed if the 
converted image signal or the converted screen threshold value 
were used, are calculated concerning respective conversion 
functions for each quarter block. The number (N RS ) of virtual 
solied pixels which is the closest to the number (N ST ) of 
reference solid pixels is selected and the conversion function 
corresponding to the selected number (N RS ) is also selected for 
each quarter block (QB). Photosensitive film is exposed on the 
basis of the converted image signal or the converted screen 
threshold value converted by the selected copnversion function, 
whereby the halftone area rate specified by the given image 
signal is attained, and the line portion is prevented to be seen 
broken.

Title: A process for the construction of hollow monolithic elements of composite material, particularly carbon fibres
IPC: B62K19/16
Filed: 1989-11-21
Abstract: The process makes use of a lost core of polystyrene, on 
which are wrapped and compacted, in successive stages, 
various sheets or mats of carbon fibre, of known type; a 
first compaction is effected in an autoclave after having 
sealingly wrapped the core, before lamination of the 
carbon fibre layers, in a first polythene envelope, and 
after having sealingly wrapped the partly finished product 
constituted by the core wrapped in the first polythene 
envelope and some of the carbon fibre sheet or mat in a 
second polythene envelope, by creation of a vacuum within 
the interior of the second envelope, whilst maintaining 
the interior of the first envelope in communication with 
the outside of the second envelope; a second compaction, 
after removal of the second envelope, following lamination 
of further sheets or mats and possible mounting of metal 
inserts on the core and insertion of the partly finished 
product thus obtained between a pair of mould halves, is 
effected in an autoclave by wrapping the two mould halves, 
preliminarily fixed together, in a third polythene 
envelope connected in a fluid-tight sealing manner to the 
first envelope and within which is created a vacuum, 
whilst the interior of the first envelope is left 
 
 
connected to the interior of the autoclave; there follows 
a polymerisation and curing in the autoclave of the 
laminated sheets or mats in a known standard cycle.

Title: Extraction tool
IPC: B25B31/00
Filed: 1992-01-31
Abstract: The extraction tool (1) for expanding sleeves (2) of anchors consists of a shank (1a) which has a conical external thread (1b) tapering towards one, free end and carries a force-application means (1c) at the other end. The shank (1a) has a central passage bore (1d), extending in the longitudinal direction, for receiving anchor bolts (4). After relieving the expanding sleeve (2) by axially driving in the anchor bolt (4), the extraction tool (1) can be screwed, by way of its external thread (1b), into the gap between the anchor bolt (4) and the expanding sleeve (2). By screwing in the extraction tool (1), the external thread (1b) cuts into the internal wall (2b) of the expanding sleeve (2) and thus forms a positive connection. By applying an axial force to the force-application means (1c), the expanding sleeve (2) can be extracted from the drill hole (9) of the receiving material (3).

Abstract: An osmotic bursting device for dispensing a beneficial agent to an aqueous environment. The device comprises a beneficial agent and osmagent surrounded at least in part by a semipermeable membrane. Alternatively the beneficial agent may also function as the osmagent. The semipermeable membrane is permeable to water and substantially impermeable to the beneficial agent and osmagent. A trigger means is attached to the semipermeable membrane (e.g., joins two capsule halves). The trigger means is activated by a pH of from 3 to 9 and triggers the eventual, but sudden, delivery of the beneficial agent. These devices enable the pH-triggered release of the beneficial agent core as a bolus by osmotic bursting.] <IMAGE>

Inventor: DUFF PAUL JOSEPH
IPC: G05D23/19
Filed: 1994-05-09
Abstract: A system controller (32) reacts to conditions that may 
arise in a plurality of discrete chiller units (10, 12, 
14) all individually controlled by dedicated control units 
(26, 28, 30). The system controller (32) reacts to 
temperature conditions of the coolant when it enters and 
when it leaves the chiller units (10, 12, 14). The system 
controller (32) normally supervises the manner in which 
the chillers (10, 12, 14) are allowed to individually 
increase or decrease chilling capacity, and overrides this 
control when the coolant entering the chiller units (10, 
12, 14) drops below a threshold value. The chilling 
capacity of all running chiller units (10, 12, 14) is 
decreased when this latter condition occurs.
