The polymer chains derived from (II) are pref. crosslinked by (III), depending on the degree of derivatisation (number of unsatd. gps./mol.). (III) is modified protein, pref. gelatin, esp. pref. hydrolysed gelatin of mol. wt. 500-10,000, derivatised with 2-40 unsatd. gps./mol. A mixt. of modified materials (III) can also be used. Polymerisation is initiated with azo cpds., peroxides, peroxy cpds., or initiators for electron beam or UV curing. The reaction mixt. can be made in batches or continuously, and then polymerised. Hydrolysed gelatin can be derivatised by reaction of the OH gps. with allyl or acryloyl chloride, or by reaction of the aminoacid units with epoxy-acrylates such as glycidyl acrylate. USE/ADVANTAGE - Provides superabsorbers with improved biodegradability, without adversely affecting the excellent water-binding properties of polyacrylate-based materials.

Title: Analogue optical transmission from laser sources to common destination - modulating laser current within range lying entirely under sloping portion of emission intensity characteristic
Inventor: AFSAR ERDAL DIPL ING
IPC: H04B10/25
Filed: 1992-06-12
Abstract: In each of several semiconductor laser sources (Q) connected to a return signal path, the quiescent current (I'B) of the laser (LS) is preset (ST) to a value near the midpoint of the sloping portion of the optical power/current characteristic. In the absence of modulation (UM) a rectifier (GL) provides a control signal (UST) holding the laser current below the threshold at which lasing begins. The control characteristic is chosen so that negative peaks of the modulation drive the current down to, but not beyond, the zero emission level. USE/ADVANTAGE - For video and audio signal distribution, network ensures optimal signal to noise ratio of all return path signals at input to detector.

Title: Capture fork pivoting device for waterski cableways, skijoring cableways and slalom ski lifts
IPC: B61B12/12
Filed: 1993-05-10
Abstract: In order to reduce the final speed of the capture fork and increase the overall speed, in particular for waterski cableways, a predominantly horizontal push/pull cylinder is provided so that the necessary curved vertical control of the capture fork by a transverse link does not influence the pivoting speed, and thus the rotational speed is slowed down instead of multiplied by five. The overall speed can be further reduced by means of a second, predominantly horizontal lifting cylinder, in particular also by virtue of the fact that the lifting cylinder contains a rapid venting device.

Patent DE-4331736-A1 (DE)
Title: Apparatus for the positioning of small textile pieces
Inventor: KOEHLER EBERHARD PROF DR ING
IPC: A41H43/02
Filed: 1993-09-19
Abstract: Known apparatuses position blank pieces, already prepositioned according to two coordinates, according to a third coordinate by means of sensors and stop strips to be adjusted according to size. The new apparatus executes independently of size a symmetrical orientation of small blank pieces according to the third coordinate, without adjusting work being necessary. The essence of the invention according to Figure 1 is that two linear photosensors (5) fixed to the frame are at a distance (8) from one another in parallel with the stop edge (6), and a positioning plate (1) is transparent in the sensor region and is moved by an actuating drive (14) together with the blank piece (12) to be positioned. At the same time, the sensor distances (8) and (10) correspond to the smallest and largest blank edge lengths (13) to be positioned. By means of the controlled actuating drive (14), all the blank edges (13) to be positioned in the size range are oriented centrally without mechanical readjustment. The size range can be varied by displacing the sensors (5) parallel to the stop edge (6) by means of suitable actuating drives. The sector of use is the automatic processing of blank pieces in the textile industry. <IMAGE>

Patent DE-4343301-A1 (DE)
Title: Sintered metal particle filter
Inventor: SCHEIDLING MATTHIAS DIPL ING
IPC: B22F3/11
Filed: 1993-12-18
Abstract: Process to produce sintered metal particle filter comprising channels closed on alternate sides,where the medium to be filtered flows through the porous walls of the filter so that the particles are sepd into the open pores of the filter wall. The filter (1) is produced from a suspension of a carrier-fluid with binders, structure binders and emulsifiers, as well as sintered metal or metal-matrix composite materials. These are charged using over/under pressure into the body mould (5) through openings (2) at the guide plates (3). A stopper (4) is later attached, enabling simultaneous prodn of the filter channel structure with alternately arranged stoppers (4), and formation of mountings, recesses or packing elements (7) for fixing the filter in a casing. The body mould (5) has movable guide plates (3) with mountings (8) to centre the channel mould body (6). The filter (I) has chambers (21) above and below the guide plates (3) to store the sinter material suspension, with the rheological behaviour of the suspension-binder-system tuned to keep the sinter materials in suspension until the forming process, ensuring a homogeneous particle distribution. The carrier fluids and binder systems are extruded from the filter (1), after which a highly sintered material is procured on the outside of the filter during sintering. A porous filter is formed with alternating closed channels, a gas-tight outer skin (11) and a defined pore structure on its channel walls (10).
