Title: Analysis of power station feed water and condensate - simultaneous and continuous verification of ammonia and salts contents
Inventor: MOSTOFIN ALEXEJ ALEXEJEVITSCH
IPC: G01N33/18
Filed: 1975-09-01
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: Hinged brake roller pair for hose drawing machine - is located between supply reel and draw rollers
Inventor: HEINRICH HARRY ING GRAD
IPC: B65H23/10
Filed: 1976-03-02
Abstract: Continuous strip material (1) which is drawn off a supply reel, is guided by roller cylinders (7-9) before it reaches the draw rollers. When a break of the strip (1) occurs, the strip movement has to be stopped suddenly. Since the inertia of the rotating supply reel is usually to great, the strip (1) between the guide rollers (7, 8) is stopped. A pair of brake rollers (2, 3) is located between the guide rollers (7, 8) and the ribbon (1) runs between the two rollers without being in contact with either one. The two brake rollers which are located parallel by two mounting bars (5), are able to swivel about a central pivot point (6). Thus when a torn ribbon is detected, the brake rollers pivot about point (6) and the ribbon between the rollers is forced to follow an S-shaped path which slows its speed.
