Abstract: 752,969. Irradiation of blood. WEHRLI, F. July 6, 1954 [July 7, 1953], No. 19711/54. Class 81(2). In an appliance for treating blood, oxygen or ozone is introduced into the blood in order to produce a foam and the blood is irradiated with ultra-violet light while in this condition. The apparatus comprises two graduated containers 5, 6 of which one 5 receives blood through a connection 7 and this passes upwards into the interior of a central tube 11, through holes in its lower end, and it is mixed with oxygen or ozone received through a central connection 8. As a result of this mixing, the blood is formed into a foam which emerges from the flared top of the tube 12 on to an inclined plate 13, whence it drops into the second vessel 6 in the liquid form, to be finally drawn off at a connection 16. The top of the apparatus comprises a cover having a quartz partition 26 through which ultra-violet light passes from a lamp 25 to the foamed blood. A complete outfit is described with reference to Fig. 1 (not shown) and comprises a trolley having cylinders of oxygen or ozone feeding through pressure reducers into the apparatus described above, from which the treated blood passes through a filter to a tube for introduction to a patient. It is also proposed to employ a pump to circulate the blood continuously, so as to give it repeated treatments and also to receive blood from a patient and then treat it and return it to him.

Title: Process for the preparation by melting of moulded bodies of a difficultly fusible alloy, and a product obtained by this process
IPC: C22C1/10
Filed: 1935-07-13
Abstract: Moulded bodies of a difficultly fusible alloy comprising a hard carbide, an auxiliary metal acting as a solvent on the carbide or as a flux, and another metal to increase the elasticity of the alloy, are formed by placing a mixture of the alloy constituents in a closed mould maintained in vacuo and heating until the constituents are melted, a light pressure being exerted on the constituents during heating which pressure is increased when fusion occurs.  The pressure may be exerted by means of graphite pistons sliding in a channel or channels in a graphite mould.  The heating may be stopped suddenly or diminished gradually and cooling may be effected in a current of hydrogen.  The mixture may comprise 85 per cent of tungsten carbide, 12 per cent of cobalt and 3 per cent of nickel or molybdenum. Copper, gold, silver and platinum may also be employed as the third constituent.
