Patent EP-0097873-A3 (EP)
Title: Tape cassette and spring element therefor
IPC: G11B23/04
Filed: 1983-06-15
Abstract: A tape cassette, in particular a video cassette, comprises two flanged reels and, between the flanges of each reel, a spring member as a biassing means to prevent the tape from slipping off the roll or folding over. The spring members can be attached to the side walls or rear wall of the housing, and their free ends constantly bear against the peripheries of the tape rolls. In specific embodiment the spring member advantageously includes the braking spring for a reel-braking device. By using a conductive material on one or both sides of the spring member and appropriately arranging the spring member relative to a tape guide element or to an element grounded on the tape recorder, it is possible to directly prevent tape loop formation, which is a cause of tape slippage and folding-over. Moreover, tape winding and unwinding are improved.
Patent EP-0103887-A3 (EP)
IPC: C12P7/00
Filed: 1983-09-20
Abstract: Disclosed are novel DNA sequences susceptible to 
expression in a microorganism in the form of synthesis of 
one or more enzymes participative in the microbiological 
oxidative degradation of a selected aromatic hydrocarbon 
substrate to a selected oxidized compound which is an 
intermediate in a multiple enzyme-catalyzed degradative 
pathway for total mineralization of said substrate. The DNA 
sequences are characterized by being substantially free from 
operative association with DNA sequences susceptible to 
expression in the form of synthesis of one or more enzymes 
participative in oxidative degradation of said selected in­
termediate compound. Illustrative of the invention is a 
plasmidborne DNA sequence of Pseudomonas putida origin 
which codes for expression, in a host microorganism such as 
E. coli, of enzymes participative in the oxidative degradation 
of naphthalene to salicylate. Cultured growth of stably 
transformed host cells in a medium including a naphthalene 
substrate results in quantitative naphthalene degradation 
and accumulation of isolatable quantities of, e.g., salicylate 
products.
Patent EP-0089086-A3 (EP)
IPC: C08F2/22
Filed: 1983-03-10
Abstract: Polymer coagulum formation during emulsion/emulsion 
polymerization procedures for forming polymeric material 
containing rubbery and relatively more rigid polymer com­
ponents is reduced by conducting the polymerizarion of the 
rubbery component in two stages. The initial stage involves 
polymerization of only a portion of the monomer charge in a 
reaction medium containing adequate surfactant so that the 
resulting polymer particles do not coalesce. The second 
stage of the polymerization involves addition of the remain­
ing monomer without the aadition of additional surfactant to 
complete polymerization of the rubbery polymer product.
Patent EP-0117940-A3 (EP)
Title: Expandable blood clot filter
IPC: A61F2/02
Filed: 1983-09-09
Abstract: A blood clot filter which is particularly suited for filtering emboli from blood circulating through the inferior vena cava. The filter is comprised of a number of strands of shape memory wire which are interconnected and wadded together to form a curly wire mesh (10). The wire strands may be substantially straightened in order to permit insertion of the filter within the lumen of an angiography catheter (40). The filter includes a number of projections (24) which serve as an anchoring means for anchoring the filter at a suitable body location within the inferior vena cava (65). One of the strands of wire includes a zig-zag which permits the attachment of the filter to the stretched distal end of a helically formed wire guide (36), thereby permitting the filter to be urged longitudinally through the lumen of the catheter (40) for positioning within the inferior vena cava. In order to implant the filter, a percutaneous catheterization is made using a femoral approach. Once inside the inferior vena cava, the filter is pushed out of the catheter using the wire guide. The filter automatically expands to fill the passageway of the inferior vena cava without causing substantial occlusion thereof.

Patent EP-0144927-A3 (EP)
Title: Method of and apparatus and machine for applying tape to a mould
IPC: B65H16/00
Filed: 1984-11-30
Abstract: An improved method and apparatus for compacting a composite tape tail which is formed by making a cut along an oblique line across the tape (2) and manipulating first and second compaction means (20,33). The cut, however, severs only the tape (22) while it is adhered to the backing (24) but does not sever the backing (24) or subjacent support (which is usually a strip of paper). The backing is then peeled away from the strip at a location between the first compaction means (shoe. blade or pad (20)) and a second compaction means (preferably a roller (33)) and conveys the discarded portion of tape to storage, disposal etc. The first compaction means (20) bears down on the assembly (2) of the tape and backing. The second compaction means (33) engages the tape (22) after the peeling away. hence bears down on only the tail (18). Only one compaction means is used at a time. The second compaction means (33) compactingly engages the tail (18) not later than the arrival of the tail leading edge (52) at said second means by which time the first compacting means (20) has stopped compacting. Power means, such as an air cylinder (44,144) move or switch the two compaction means into and out of respective positions for compaction so that the full width tape is compacted by the first compaction means and the tail (oblique strip without any backing) is compacted by the second compaction means.
Patent EP-0114748-A3 (EP)
Title: Road and engine speed governor
IPC: B60K31/00
Filed: 1984-01-19
Abstract: A governor (20) governs engine and load speed and is especially adapted for use with motor vehicles. It comprises an overriding throttle closing device (36) with a linear actuator (64) for moving the device to a position for limiting the engine speed and load speed to governed values. An electronic control circuit (66) comprising a microprocessor operating under program control produces motor control signals for a reversible electric motor (62) which drives the actuator through a gear train (92, 94, 96) and lead screw (84). An engine speed signal generator provides an electrical speed signal to the control circuit and a road speed signal generator supplies a load speed signal to the control circuit. When the speed signal exceeds a predetermined value, the control circuit produces motor control signals for operating the motor at full speed to move the actuator to a reference position causing operation in a reference point governing mode. In this mode when the speed signal exceeds the governed value, the control circuit produces motor control circuits for operation of the motor at slow speed in the close throttle direction. When the speed signal is less than the governed speed, the control circuit produces motor control signals for operating the motor at slow speed in the wide open throttle direction.

Filed: 1986-04-25
Abstract: A system for controlled release both in vivo and in vitro 
of entrapped substances, either at a constant rate over a 
period of time or in discrete pulses, is disclosed. Biologically 
active substances, such as drugs, hormones, enzymes, 
genetic material, antigens including viruses, vaccines or 
inorganic material such as dyes and nutrients, are entrapped 
in liposomes which are protected from the biological en 
vironment by encapsulation within semi-permeable micro-­
capsules or a permeable polymeric matrix. Release of the 
entrapped substance into the surrounding environment is 
governed by the permeability of both the liposome and 
surrounding matrix to the substance. Permeability of the 
liposome is engineered by modifying the composition and 
method for making the liposomes, thereby producing lipo­
somes which are sensitive to a specific stimuli such as 
temperature, pH, or light; or by including a phospholipase 
within some or all of the liposomes or the surrounding 
matrix; or by destabilizing the liposome to break down over 
a period of time; or by any combination of these features.
