Title: Soln. for hydrophobic treatment of ink jet exit - has lower and higher b.pt. constituent to control evapn. rate and give better spreading with more uniform treatment
Inventor: SENGE CARSTEN DIPL ING
IPC: B41J2/16
Filed: 1992-03-06
Abstract: A surface, esp. the exit plane of an ink jet printing hed, is made hydrophobic by treating it with a soln. of long chain, halogen, contg. copolymers and a crosslinking agent. The soln. contains a second solvent with a different b.pt. so that the first solvent effectively evaporates while the second solvent only evaporates after a hydrophobic layer has formed. One solvent can be tert. butyl acetate while the other solvent is gamma-butyrolactone in the ratio 10-30, pref. 20:1. The soln. (30) is sprayed from a nozzle (40) on to the surface to be treated at time to at a low viscosity la and arrives at the surface at time t1, the delay depending on the process parameters. During this time the first solvent has virtually evaporated with a corresp. increase in viscosity. When the soln. reaches the surface, the viscosity is determined by the higher b.pt. solvent which then controls spreading on the surface until crosslinking is complete at time t2. USE/ADVANTAGE - The process achieves a more uniform coating and avoids the formation of islands where the coating has missed.

Title: Use of C1-inactivator - to combat complications e.g. generalised oedema and refractory hypotension resulting from bone marrow transplants.
Inventor: EISELE BERND DR
IPC: A61K38/57
Filed: 1992-08-24
Abstract: C1-inactivator is used to control complications arising from bone marrow transplants. USE - The C1-inactivator combats the symptoms such as generalised oedema and refractory hypotension produced by activation of the kallikrein system after therapeutically or prophylactically indicated bone marrow transplants, where there is not enough C1-inactivator produced naturally to control the kallikrein system. Suitable daily doses are 1-5000 (esp. 5-1000) units/kg. administered intravenously (bolus or infusion) intramuscularly or subcutaneously. Solid pharmaceutical forms contain 1-3000000 (esp. 50-60000) units daily, for use p.o. or rectally. In an example, the patients with therapeutically or prophylactically indicated bone marrow transplants were given C1-inactivator concentrate in doses as follows. Initial dose 6.0 units/kg after 12 hrs. 15 units/kg after 12 hrs. 15 units/kg, after 12 hrs 15 units/kg and after a final 12 hrs. 15 units/kg.

Title: Blind-stitch sewing machine - has feed belt mechanism in front of fabric advance with an adjusted feed rate for smooth movement
Inventor: KITAMURA HIDEO
IPC: D05B27/10
Filed: 1993-02-11
Abstract: The blindstitch sewing machine has an auxiliary mechanism to feed the fabric to a stitching position before the advance mechanism of the sewing machine body, through belts in friction contact with the lower surface of the fabric. A mechanism sets the fabric feed rate applied by the belts. Pref. the adjusted feed rate for the belts of the mechanism gives a synchronised fabric movement, by time, between the feed through the mechanism and the advance feed through the main body of the sewing machine. The feed rate can also differ from the fabric feed speed through the centre of the sewing machine advance mechanism. USE/ADVANTAGE - The blindstitch sewing machine is used for applications such as an edge seam for a garment. The fabric feed ensures that the material passes smoothly through the stitching point, from the start to the end, without bunching or excessive tension.

Abstract: PCT No. PCT/EP94/00832 Sec. 371 Date Sep. 14, 1995 Sec. 102(e) Date Sep. 14, 1995 PCT Filed Mar. 16, 1994 PCT Pub. No. WO94/21941 PCT Pub. Date Sep. 29, 1994The invention concerns a continuously variable transmission having a driving and a driven shaft (1, 9) and first and second intermediate shafts (10, 11). Power is transmitted to the driven shaft (9) through a transmission variometer with i2 arrangement. According to the invention, the input power of the transmission is transmitted to the driven shaft through a transmission branch with constant ratio and through the continuously variable transmission branch. This power distribution reduces the proportion of the power transmitted through the continuously variable transmission branch. The transmission efficiency of the whole transmission may, in particular, be thus improved. This continuously variable transmission is designed for use in private cars and light utility vehicles.
