Title: Grooved rotary piston valve - has widening grooves which offer continuously adjustable pulse width for transfer of pressure fluid
Inventor: FRIEDRICHS FRIEDRICH WILHELM I
IPC: F15B21/12
Filed: 1976-02-04
Abstract: The control piston (1) fits into a cylinder (4) with an inlet port (P) and a double outlet port (T). As the piston rotates its grooves connect the working port (A) alternately with the inlet (P) and outlet (T) and a second working port (B) operates in opposition to the first. The width of the piston's grooves differs at different positions and the piston slides longitudinally. Moving the piston further into or out of, its cylinder, alters the proportions of time for which a working port is connected to the supply and to the outlet. As the groove width varies continuousy the adjustment also is continuous.

Abstract: A synthetic zeolite with faujasite crystal structure and of formula Na2O.Al2O3(2.5 plus-or-minus 0.5)SiO2.nH2O (n = 0-8) is prepd. by pptn. and crystallisation of faujasite-aluminosilicate gel from a reaction mixt. contg. Na2O, Al2O3, SiO2 and H2O in molar proportions as SiO2/Al2O3, Na2O/SiO2, and H2O/Na2O of (a) 2.5-15.0, 0.7-1.2 and 25-100 respectively, (b) 2.5-15.0, 1.5-6.0 and 25-100 respectively, and (c) 5.0-15.0, 1.2-1.5 and 25-100 respectively. Crystallisation is carried out at a temp. 60-105 degrees C in the presence of zeolite A, of which over 30% of particles are smaller than 1 micron (radius). The process does not require a pretreatment and a hydrothermal crystallisation is effected directly after pptn. and by stirring mechanically, which reduces the synthesis time from the usual 30 hrs. to 2-6 hrs.
