Inventor: GREEN CHARLES J
IPC: F16K17/36
Filed: 1982-04-19
Abstract: A tank venting, pressure and temperature relieving, and spill preventing valve for fuel tanks. The valve has a spin chamber (94), having generally circular cross sections and at least one side wall inlet opening (106) that is tangentially directed with respect to the circumferences of the cross sections. There is a circular outlet (80) at a normally upper and open end of the chamber. The chamber cross sections decrease in diameter upwardly of the inlet opening to below the outlet opening whereby gas venting through the chamber spins a light weight, buoyant ball (90) around the chamber so as to prevent the ball from closing during venting. The ball valve is adapted to be lifted to seat (88) on the outlet to close it when liquid enters the chamber to a predetermined level. A heavy ball (92) in the chamber holds the light weight valve ball on the seat when the chamber has been tilted a predetermined amount. There is a second heavy ball (84) externally of the chamber adjacent the outlet opening and adapted to move the light weight valve ball off the seat when the liquid is below a predetermined level and the chamber is not tilted, so that the outlet will be open for venting.

Abstract: The worms are fed in accordance with a continuously growing nutritional chain (28, 29) in a manner such that a migration of a work population following said chain is produced. At least once an accretion (5) of the worm population is separated therefrom, leaving a migrating stock population (6) in the nutritional chain (28, 29), whereas the accretion (5) migrates in the direction of an accretion nutritional chain which starts from the stock nutritional chain, and can be harvested therefrom. Means, e.g., inhibiting means (20), anti-creep means, supplying means, and heat-exchanging means, are described for raising the worm under conditions which are optimal for the farmer and depend, for instance, on economical and on season conditions. 
<??>The method and/or device can be advantageously used for producing work casting, since the worms can be maintained under conditions, whereby the nutrition conversion velocity of the nutrition offered to the worms is maximal over a long period of time.

A power supply for the beam gun is constructed to produce a series of successive, time-spaced groups of discrete, timespaced electrical pulses to produce the said series of the pulsed energy beams. A highly precise, subtle control of the energy flow of the beamed radiation onto the workpiece is achieved in this manner by controlling the time duration  T on and the time interval Toff of the electrical pulses, the time duration Ton and the time interval Toff of the groups and the numbern of the electrical pulses in each of the groups.
