A method for determining the presence of an analyte in a fluid is described along with an apparatus specifically designed to carry out the method. The method involves taking a reflectance reading from one surface (15) of an inert porous matrix (11) impregnated with a reagent that will interact with the analyte to produce a light-absorbing reaction product when the fluid being analysed is applied t...

The subject of the invention is a window (1) provided with an elastically flexible profiled sealing strip (4). In order to fix the profiled sealing strip (4) to the window (1), a profiled bead (8) is adhesively bonded to the window (1), and the profiled sealing strip (4) is fixed to this bead. The profiled bead (8) consists of a hardened adhesive material and is formed by extrusion with the aid of...

A pharmaceutical combination consisting of dipyridamole or mopidamol and O-acetylsalicylic acid or the physiologically tolerated salts thereof is used for the specific prevention of thrombus formation.

In a pay television system a programme signal is transmitted scrambled to prevent its authorised reception, the scrambled signal being accompanied by authorisation codes, one for each authorised subscriber, a subscription key and a pay-per-view key. At a receiver if the appropriate authorisation code is received the receiver functions in the subscription mode in which mode the subscription key pro...

Cross heat exchanger comprises a number of square plates (2) arranged in a stock with reparator pieces and side pieces that permit a flow and a perpendicular flour (B), the two flow directions alternating through the stack. Each plate has a quadratic or wave shaped surface to control the movement of the air mass. There are sealing pieces which preferally are strips of glass reinforced polyester bo...

A recombinant virus characterised in that it contains all or part of the sequence of a specific antigen of a tumour and in that it is employed by way of prevention or cure, to cause the rejection of the corresponding tumour in man or in animals.
