Title: Process for preparing copolymers of monoethylenically unsaturated mono- and dicarboxylic acids (anhydride)
IPC: C08F220/04
Filed: 1983-09-06
Abstract: 1. A process for the preparation of a copolymer, having a K value of from 8 to 80 and containing copolymerized units of monoethylenically unsaturated mono- and dicarboxylic acids, by free-radical copolymerization of (a) from 10 to 60 % by weight of maleic anhydride, citraconic anhydride, itaconic anhydride or a mixture thereof, (b) from 90 to 40 % by weight of acrylic acid, methacrylic acid, vinylacetic acid or a mixture thereof, and (c) from 0 to 20 % by weight of another, carboxyl-free monoethylenically unsaturated monomer which is copolymerizable with (a) and (b), the percentages being based on the polymer, wherein the copolymerization is carried out as a precipitation polymerization in a C1 -C3 -alkyl-substituted benzene hydrocarbon or aliphatic halohydrocarbon as solvent other than benzene, in which solvent the monomers are soluble and the copolymer is insoluble, in the presence of from 0,05 to 4 % by weight of a protective colloid and from 2 to 5 % by weight of a free-radical initiator, the percentages being based in each case on the monomers, at least one third of the dicarboxylic acid anhydride to be employed being initially charged into the reactor and the remainder being metered in over not more than two thirds of the feed time of from 2 to 10 hours for the monocarboxylic acid, and the polymerization is initiated at from 50 to 100 degrees C and completed at from 130 to 180 degrees C.
Patent EP-0121008-A3 (EP)
IPC: A61L33/00
Filed: 1983-03-29
Abstract: A coating and integral treatment for improving the 
biophysical stability of bioprosthetic devices after implanta­
tion, particularly with respect to calcification, and, specifically, 
a method for treating animal tissues, such as heart valves, to 
provide improved biophysical stability in allograft and 
heterograft transplanations. The increased stability results, 
in-part, from the creation of a three-dimensional matrix of a 
primary structural component of the prosthetic device and 
covalently attached calcification inhibitors. Other materials, 
some having additional stabilizing effects, may be utilized to 
form additional bridges or fill the interstitial gaps in the mat­
rix. After implantation, the resultant modified device exhibits 
minimal surface for intramatrix growth of calcium phosphate 
crystals, and additionally, may inhibit platelet aggregation, 
enzymatic degradation and host rejection, while minimizing 
the risk of mechanical failure, in the host organism.
Patent EP-0106433-A3 (EP)
IPC: F02G1/02
Filed: 1983-06-20
Abstract: Engine powered by extracting heat from a flow of 
internal combustion engine exhaust gases or other fluid 
medium has input and output flow control gates (10,14) 
defining a controlled section of a duct (12) along which said 
flow passes, the gates operating to pass the flow continuous­
ly along that section while maintaining a pressure differential 
therein. A pressure drop or rise in that section is continuous­
ly provided by cooling or injection of fluid to be vaporised so 
as to extract heat from the medium and this pressure 
differential drives a motor (18) and/or itself drives the gates 
to provide useful work, for example driving an electric 
generator (25).
Patent EP-0109735-A3 (EP)
IPC: H01R43/01
Filed: 1983-09-19
Abstract: Machine for interconnecting wire-in-slot type terminals 
(32) in connectors (30, 42) mounted on a panel board (20) 
utilizes a wire feel wheel (70), rotatable insertion tooling (10, 
and an X-Y table (16). Wire (22) is fed vertically through a 
rotation housing (150) past wire inserters (170, 175) mounted 
above an aperture (53) in a rotary plate (52). Wires (22) are 
positioned for termination by wire feeding and movement of 
the X-Y table (16) on which the panel board (20) is mounted. 
Independently pivotable idler wheels (72) cooperate with the 
feed wheel (70) to engage one or two wires (22). Insertion is 
effected by downward movement of the rotation housing 
(150) which drives the inserters (170, 175) through the 
aperture (53) in the rotary plate (52). The rotation housing 
(150) is moved by pivoting a yoke (113) with a variable pivot 
point (114) to change limits of travel and therefore insertion 
depth. The plate (52), inserters (170, 175), and rotation 
housing (150) may be rotated to four orthogonal orientations 
to insert wires (22) in terminals (32) having four respective 
orientations. Through-wire type inserters (170) may be 
shifted laterally on the rotary plate (52) by solenoids (219) so 
that wire cutt-off type inserters (175) will be poised above the 
aperture (53) in the rotary plate (52), making the apparatus 
capable of threading a wire (22) through several connectors 
(30) prior to cutting it.

Abstract: A service tool to be fitted to a tractor to extract and 
support the cover 2 of the housing 2A of a hydraulic lift 
mechanism. The tool includes a hoist 9 by which the cover 2 
is lifted from the housing. The hoist 9 is supported on a 
pivotal structure comprising rigid links 4, 10 and the 
structure is swung bodily together with the hoist 9 and the 
cover 2 after it has been raised and secured to the hoist 9 in a 
clockwise direction, as viewed in Figure 2, to withdraw the 
cover 2 from a position beneath the cab 3 of the tractor. The 
pivotal movement of the links 4 and 10 is limited by a 
stop-pin 17 slidable in a slotted arm 14 also forming part of 
the structure. The hoist 9 together with the cover 2 is then 
swung about a pivot 7 to invert the cover, the arm 14 holding 
the inverted cover 2 displaced laterally from the housing 2A.

Abstract: The invention comprises of an anionic polyelectrolyte 
hydrogel reversibly cross-linked with a polyvalent metal 
cation having a valence of at least two. This hydrogel may be
