Title: Inhibiting blood-clotting properties on, e.g., catheters and tubing - by treatment with soln. contg. basic peptide as enzyme inhibitor
Inventor: KUEHLEIN GEORG
IPC: A61L33/12
Filed: 1991-11-11
Abstract: Process for equipping medical materials (e.g. catheters, tubing, containers, formed parts, etc.) with blood-clotting inhibiting properties so that these materials obtain a layer of physiological clotting inhibitor in the areas of contact with bood or similar substances comprises treating the surfaces (which carry anions) with a soln. contg. a base peptide as enzyme inhibitor so that this is taken up by the surfaces immediately prior to the use of the medical material. The enzyme inhibitor is aprotinin (added to the soln. in wt. ratios of 20000-5 mio kalikrein inhibitor units) or a salt of a rare earth element, esp. Neodyminm (added to the soln. in wt. ratios of 0.05:10 wt.%). Also added to the soln. are 0.1-5.0 wt.% of the directly-active amt. coagulents sulphinpyrazon, dipyridanol, phenylbutazone or acetylsalicylic acid. USE/ADVANTAGE - Use of the process means that the medical materials are not recognised as foreign bodies by bood. The risk of thrombosis is also much lower than achieved by prior art processes

Title: Sewing neck-band around neck of garment including inside label - includes simultaneously dispensing neck-band material to sewing point and fitting together with garment w.r.t. automatic stitch count
Inventor: ADAMSKI JUN MAXIMILIAN
IPC: D05B35/08
Filed: 1992-06-02
Abstract: In a process to sew on a neck-band, around the neck of a garment, and to include an inside label beneath the back of the band, garment is placed on the machine, and at the same time the neck-band material is automatically dispensed to the sewing point. The fitting together coincides with the stitch count automatically, with the count beginning at a shoulder hem. The label is positioned and sewn in similarly. The sewing machine has a stitch mechanism (40) at one end, and a stitch counter at the other end. This works in conjunction with an electronic monitor which performs the calculation when the sensor unit (79) encounters the shoulder hem of the garment. Sewing then commences, and the neck-band material is guided and measured through (62,63), from a reel of material, working in conjunction with the sensor (79), the plate (67) with the hole (68) for the sensor light. The presserfoot (80) descends and stitching commences, with a calculated number of stitches and also a measurement of time. Progress may be monitored, and the operator has a control panel, so that the machine can be adapted to various sizes of garment. ADVANTAGE - The garment is quickly processed, with a considerable saving in operator supervision. The quality is enhanced by correct fitting and sewing, and the position of the label. The operator can see the machine in operation, and check the process.

Title: Moulding flat honeycomb sheet e.g. as core of sandwich material - by placing it on suitably cut e.g. metal plate, enveloping assembly twice in air-tight film, vacuum forming to shape and curing in oven
Inventor: EBERLE WALTER
IPC: B29C53/04
Filed: 1992-10-02
Abstract: Flat sheets of honeycomb material, such as a honeycomb core of sandwich constructions, are bent by loading in one position over a suitable profile using air pressure; in the process, the sheet concerned is positioned on a flat support which can be bent to the desired profile; it is then fixed by vacuum applied to an air-tight chamber enclosing the sheet; the combination of materials with the supporting plate is positioned over the shaped surface and given a second covering to form an air-tight space, after which a vacuum is applied to mould the support plate to the profile. The honeycomb sheet is positioned on a supporting plate which is divided into segments that are joined together at least at their centre; the honeycomb is then fixed by evacuating an air-tight film envelope round the honeycomb and the supporting plate. Typically, a circular flat sheet of honeycomb (e.g. phenolic-impregnated paper type) is first laid on a similar round plate (3) of 0.8 mm thick aluminium which is cut radially into a series of segments joined together at the centre. ADVANTAGE - The procedure enables a flat sheet to be moulded three-dimensionally, e.g. into a partly spherical shape.

Patent DE-4239178-A1 (DE)
Inventor: BECK ERHARD DIPL ING
IPC: B60T8/50
Filed: 1992-11-21
Abstract: A brake pressure regulator with an antilock system and/or drive slip control has one or several electromagnetic valves (3, 4), valve receiving bodies (1) which receive pressure medium channels (19, 30, 8), and a hydraulically actuated sliding valve (2) integrated into a reception bore (14) of the valve receiving body (1) which regulates the pressure medium volume between a pressure medium source (6) and a pressure medium consumer (16) depending on the switching position of the electromagnetic valves (3, 4). Pressure medium channels (19, 20) hydraulically linked through an inlet valve (3) to the pressure medium consumer (16) open into both front faces (17, 18) of the sliding valve (2). The sliding valve (2) has a ring-shaped groove (7) provided with a driving edge (9) which links the pressure medium source (6) to the inlet valve (3) through an inlet channel (8). The thought at the basis of the invention is to prevent leakage flows by an appropriate arrangement of pressure medium channels and sealing elements and to guide the pressure medium flow in the desired direction.
