Patent NO-174327-C (NO)
Inventor: KOLSET EINAR
IPC: A63C5/00
Filed: 1992-03-30
Abstract: This invention relates to a jumping ski which is particularly adapted to the so called V-style. The ski according to the present invention has a cross-section with a flat base and longitudinal running grooves and a smooth curved upper side, which, together with the underside, forms an aerodynamic wing profile having its maximum camber nearest to the centre line (S). Additionally the cross section of the ski is twisted in towards the centre line (S), such that the angle of attack of the ski tip towards the air is reduced, in order to avoid stalling whilst in flight. The ski boots are fastened to a flat area where the cross section of the ski is rectangular and, in a plan view, makes a skew parallelogram. <IMAGE>

Title: Improvements relating to the administration of pharmaceutical agents
Inventor: EDGAR BO
IPC: A61K31/44
Filed: 1990-11-27
Granted: 2003-01-28
Abstract: The bioavailability of pharmaceutical agents susceptible to oxidation by cytochrome P-450, particularly anti-hypertensive dihydropyridines such as felodopine or nifedipine can be increased by administering, before, during or after the administration of the pharmaceutical agent, a flavonoid in the aglucone or glycoside form. This conjoint administration has the effect of prolonging the bioavailability of and so reducing the amount of pharmaceutical agent that needs to be administered.      Grapefruit juice has been found to be a suitable source of the flavonoid.

Abstract: Transmission series with a variable gear stage (variation stage) consisting of a pair of gearwheels. Within the series, the variation stage encompasses a range of permissible sizes (Bi = B1... Bm) which in each case have the same centre distances (Ai = A1 ... Am). The same range of permissible transmission ratios (Ii = I1... In) is provided for all sizes, so that the centre distances (Ai) and the transmission ratios (Ii) form a matrix (M). The number of components required is substantially reduced by correlating the graduation of the centre distances (Ai) and the graduation of the transmission ratios (Ii) in such a way that the same gearwheel is used in a variation stage sequence (S) comprising a number of variation stage sizes.

Title: Cryogenic distillation process for the production of oxygen and nitrogen
Inventor: HA BAO
IPC: F25J3/04
Filed: 1993-02-08
Granted: 2003-10-07
Abstract: According to the invention, an intermediate column having its lower end in heat exchange with the top of the high pressure column, and its upper end in heat exchange with an intermediate location above the bottom tray of the lower pressure column is used. This intermediate column separates the oxygen rich liquid produced at the bottom of the high pressure column into two liquid fractions which are then introduced as feeds to the low pressure column, which still has it's lower end in heat exchange with the top of the high pressure column, therefore, its pressure will be essentially the same as the low pressure column of a classical double column process operated at the same air pressure.
