Title: Ink jet printing-plotting appts. - has heated fixing unit following printing stage to improve throughput
Inventor: IWATA KAZUYA
IPC: B41J11/00
Filed: 1990-06-19
Abstract: An ink jet printer-plotter has the facility to vary the ink fixing time to suit the specific conditions associated with  different characters, etc. The printer has a head (6) mounted on a carriage (7) that moves along guides relative to a sheet of material (1). A feed roller (4) moves the paper relative to the head. After passing over the head, the paper moves across a fixing unit (8) that has a heating surface (8a). This accelerates the drying of the ink and allows faster processing. ADVANTAGE - Improves fixing process for improved handling.

Title: Two stage telescopic hydraulic cylinder - has stages operating in controlled sequence via valving
Inventor: BRAECKELMANN GERD
IPC: F15B15/16
Filed: 1990-07-05
Abstract: The two-stage telescopic hydraulic cylinder has an outer cylinder (11) in which a first piston (12) operates. This first piston has a hollow upper part which forms a second cylinder for the second piston (13). - Hydraulic fluid is supplied through a valve (17) to the outer cylinder (11) and acts on the first piston. When the first piston has reached the upper end of its stroke, the radial hole in the piston is aligned with the port (161) in the outer cylinder wall. Hydraulic fluid then flows to the underside of the second piston which is pressed upwards. The two parts of the telescopic cylinder are thus operated in a controlled sequence.

Patent DE-4028592-A1 (DE)
Inventor: MAUCH MICHAEL
IPC: B65G1/04
Filed: 1990-09-08
Abstract: The invention concerns a vehicle-parking system (1) with a number of vehicle pallets (4) which can be displaced on a planar network of tracks running at right angles to each other. Each pallet has its own drive unit which drives rollers which move the pallet (4). In order to enable the direction of travel of the pallet to be selected exclusively by means of fixed control means, the invention proposes that the drive unit simultaneously drives the rollers for both the mutually perpendicular directions of travel (6, 7). Located along the tracks are fixed rails (8, 9) which can be selectively brought into contact with the rollers for either one or the other of the two mutually perpendicular directions of travel (6, 7).

This complex, after contact with a suitable enzyme substrate, will produce a difference between the specified symbol and the rest of the test zone which can be detected by the eye. Also new is a kit comprising, apart from the dipstick, a soln. of Ab and a soln.  of substrate which generates an insoluble coloured product in contact with Ab. (I) is an antigen, hapten or antibody. The base is made of plastic or glass, and the test zone of nylon, (nitro)cellulose, fibre glass, polysulphone poly(vinylidene fluoride) or polyester.  The reaction zone may also include an enzyme inhibitor (II; not in the region representing the symbol) and a polyol (III). USE/ADVANTAGE - This device obviates the need for a washing step generally required in dipstick assays, and can be used successfully by relatively untrained personnel. It can be used to assay antibodies, antigens or haptens, or for gene screening and for detection of genetic sequences (using immobilised complementary seuqences and labelled nucleii acid probes). The presence of (II) and (III) intensifies the colour difference between symbol and the rest of the zone.
