Patent EP-0354760-A3 (EP)
IPC: E21D20/02
Filed: 1989-08-08
Abstract: A roof anchor (10) for supporting an underground mine roof (12) 
has an elongated 
shaft (16) with a head (20) formed at one end. The head (20) supports a 
washer (23) and a roof supporting plate (24) that surrounds the mouth of 
a blind bore (14) formed upwardly into the roof. A resin capsule (32) 
is positioned within the blind bore (14) above the roof anchor (10). 
The shaft (16) of the roof anchor has an adjustably securable 
annular washer (26) surrounding the shaft. The annular washer (26) is 
fixed in a position so that when the resin capsule (32) is ruptured 
to release the resin to bind the roof anchor (10) within the bore 
hole, the resin completely fills the bore hole from the blind 
end of the bore to the rigid annular washer (26) fixed to the shaft 
of the roof anchor. By making the position of the annular 
washer axially adjustable, the roof anchor may be utilized with 
varying amounts of resin as conditions at the mine site require 
and still cause the resin to be subjected to a compressive 
force within the bore hole in the space between the end of the 
bore hole and the annular washer.

Title: Graft copolymers
IPC: C08F291/08
Filed: 1989-08-24
Abstract: A graft copolymer is made by grafting, by a free 
radical reaction mechanism in aqueous solution, water 
soluble ethylenically unsaturated monomeric material on 
to a water soluble substrate having hydroxyl groups, and 
the free radicals are formed on the substrate using an 
oxidising metal capable of being reduced by the substrate 
to a lower valency state (for instance cerium) and 
persulphate or other peroxy compound capable of oxidising 
the metal back to a higher valency state. The process 
is preferably conducted as a reverse phase polymerisation 
process and the invention includes also a novel reverse 
phase emulsion comprising a dispersion of reverse phase 
polymer particles of a graft copolymer of carboxymethyl 
cellulose, dextran or starch with acrylamide and acrylic 
acid and/or AMPS.

Patent EP-0401635-A3 (EP)
IPC: H01L29/84
Filed: 1990-05-28
Abstract: A first substrate (100) having a working region 
(110), a flexible region (120), and a fixed region 
(130) is prepared. Resistance elements (R) are 
formed within the flexible region on a first surface 
of this substrate. A portion of the first substrate 
is remove. Thus, the flexible region is allowed to 
have flexibility. A second substrate (200) is 
connected to a second surface of the first 
substrate. The second substrate is cut later into 
two portions of a working portion (210) and a 
pedestal (220). The working portion is connected to 
the working region of the first substrate, and the 
pedestal is connected to the fixed region of the 
first substrate. In order to control displacements 
in upward and downward directions of the working 
portion, control substrates (300, 400) are further 
connected. A force applied to the working portion 
by acceleration or magnetism is detected as changes 
in the resistance values of the resistance elements.

Title: Sphincterotomy device having controlled bending and orientation
IPC: A61B17/28
Filed: 1990-02-05
Abstract: A sphincterotome (21), such as a papillotome, is 
disclosed for surgical cutting using an electrically 
conductive cutter wire (33). The sphincterotome (21) 
includes a multi-lumen tubular member (27), with one lumen 
(55) having an electrical conductor (43) disposed therein, 
and the other lumen (57) having a reinforcing wire (45) 
disposed therein. The reinforcing wire (45) is preferably 
rectangular in cross-section, providing a greater moment of 
inertia in a resisting axis R than in a bending axis B. 
Accordingly, the cutting edge (53) of the cutting wire (33) 
may be oriented to the 12 o'clock position of the papillary 
orifice to avoid injury to the duodenal wall or pancreatic 
duct (69) in the patient, and to maintain the cutting edge 
(53) in a predetermined cutting plane P. Fluoroscopic 
indicating stripes (39, 41) may be provided at the distal

Title: Adjustable support device for surgery
IPC: A61G13/12
Filed: 1990-03-15
Abstract: An adjustable patient support which is 
particularly useful in spinal surgery, comprises a 
base (10), first and second support members (32,34) 
extending upwardly from the base and being slidably 
located in an elongate guide (26) in the base. A 
threaded bar (62) is mounted for rotation about its 
longitudinal axis which is aligned parallel to the 
longitudinal axis of the guide (26), and is provided 
with two portions threaded in opposite senses. Each 
threaded portion is received in a complementarily-­
shaped recess in a respective one of the support 
members (32,34), whereby rotation of the bar causes 
relative movement of the two support members along the 
guide groove. The support members each comprise a 
base portion and a patient engagement portion, and 
there are means for adjusting the height of the 
patient engagement portion.  
     The invention permits unobstructed access to the 
spine, and since the majority of the weight of the 
patient is supported on the device, the blockage of 
arteries and veins is alleviated or prevented. The 
device also allows an anaesthetist to check that the 
patient is still breathing, by feeling the movement of 
the patient's abdomen.

Abstract: The control system contains a sensor unit (18) with a dynamically synchronised gyroscope which contains two linear accelerometers allocated to orthogonal measuring axes and responds to azimuthal and pitching movements. The sensor unit is located in a housing (28) which is reproducibly guided in a running tube (16).
