Title: Metering pipette with exchangeable ends - having piston which protrudes into pipette to reduce dead space
IPC: B01L3/02
Filed: 1975-03-25
Abstract: Metering pipette which can such up and deliver a constant preuse volume of liquid and which can be immediately reused for a second different liquid has an exchangeable element which is made without relatively close or precise tolerances. Into this the liquid is drawn by means of a piston device and subsequently expelled. The liquid does not touch this piston to contaminate it yet only a negligible dead space remains between the piston and the exchangeable element. The piston is tubular in form and extends down into the pipette element. In order to reduce the dead space, the element is virtually filled by the piston, the top end of which however runs in a separate cylinder. For the accurate repetitive measurement and dosing of small quantities of liquid esp. where several different liquids are being handled. The design combines the advantages of the two main types of replaceable automatic pipettes already known.

Title: Analysis of power station feed water and condensate - simultaneous and continuous verification of ammonia and salts contents
Inventor: MOSTOFIN A A
IPC: G01N27/06
Filed: 1975-10-20
Abstract: In a device for analysing samples of power station boiler feed water and condensate, the choke valve at the steam/gas outlet of the first of a series of vapourisers, arranged one behind the other in the line of motion of the fluid phase of the sample, has a smaller opening for the passage of the steam/gas mixture, than the chokes of the other vapourisers. The opening is of such a size that a height of fluid is maintained sufficient to ensure that largely only the CO2 is removed. Between the first and the following vapourisers there is a conductivity monitor the output signal of which corresponds to the ammonia content of the fluid phase. Considerable savings can be made annually, especially in large installations. The number of samples taken is halved, one analysis only being necessary for both salt and ammonia contents.

Title: Hot working large refractory alloy blanks - by enclosing in a sheath before deforming
Inventor: DECOURS JACQUES
IPC: B21C37/02
Filed: 1976-04-14
Abstract: Large parts made of refractory alloys are plastically deformed by placing the part in an sheath of thickness >0.5 mm, the sheath having a lower resistance hot plastic deformation than the part, and plastically deforming the alloy in the heated state. The sheath is subsequently removed. Refractory alloys normally difficult to hot work are shaped into tubes, wires, bars, etc. The composite part/sheath is easier to deform than the part on its own. The sheath retains the heat ensuring that the part is practically at a uniform temp. Defects in the refractory alloy are avoided. In the case of drawing the sheath transmits the pressure to the part and the process is almost hydrostatic.
