Patent DE-3719107-A1 (DE)
Title: Flow control valve
Inventor: RIDDER JOSEF
IPC: B67C3/28
Filed: 1987-06-06
Abstract: A quick-opening and quick-closing flow control valve consists of a three-part valve body, in which a sealing cylinder is clamped. A piston, having a plate-shaped piston rod corresponding to an oppositely arranged piston, acts approximately concentrically on the sealing cylinder so that the latter is so deformed, i.e. compressed, in this area that the flow cross-section is effectively closed. After the pressurised medium supply is shut off, the product to be metered, which occupies the flow cross-section fully, reopens the sealing cylinder automatically so that it can then pass freely through the valve body. <IMAGE>

Title: Method of lowering a tubular foundation element as well as apparatus for carrying out the method
IPC: E02D7/24
Filed: 1987-08-08
Abstract: To lower a tubular foundation element (1) having a circular cross-section at least in the foot area, the soil is removed from the inner space of the foundation element by jetting. The jetting medium is fed through an inlet line (4) running along the foundation element (1) and having a jetting device (15) arranged in the foot area, and the jetted material is delivered to the outside likewise by an outlet line (5) running along the foundation element (1) and having an entry opening (16) arranged in the foot area and a discharge opening lying above the surface of the ground. The inlet and outlet lines (4 and 5 resp.) are provided at uniform distances from one another with closable feed and discharge openings (6 and 7 resp.) so that in the course of the lowering of the foundation element (1) jetting medium or jetted material can in each case be admitted to the feed and discharge openings (6 and 7 resp.) lying nearest to the surface of the ground. This enables work to be carried out in a timed sequence in each case at ground level. Since the extraction of the soil is effected by jetting in the tube interior, the soil surrounding the foundation element is not disturbed. <IMAGE>

Title: Waveguide arrangement for low-attenuation transmission of microwaves of the dominant mode
Inventor: KAFFENBERGER ERNST DIPL ING
IPC: H01P3/12
Filed: 1988-10-26
Abstract: It is intended to specify a waveguide arrangement which transmits microwaves of the dominant mode with as little attenuation as possible, using means of little complexity. A transition waveguide (HL2), which consists of a plurality of sections (A1...A7) of graduated cross-section, is connected to at least one end of a multi-mode transmission waveguide (HL1). Arranged at the side of the transition waveguide (HL2) is at least one chamber (K11, K12, K21, K22) which is at least partially filled with an absorbent material (A3) and is coupled to the transition waveguide (HL2) at a point where it is possible to output only at least one higher mode and not the dominant mode. Those sections (A1) of the transition waveguide in which other higher modes are capable of existence, for which no output is provided, and those sections (A2) which are adjacent to these sections and cause periodic attenuation of the said modes are dimensioned in terms of their length such that forward-running and backward-running wave elements which occur in these sections (A1, A2) of each mode are superimposed in antiphase. This waveguide arrangement is particularly suitable for the transmission of the dominant mode at frequencies which are greater than twice its cut-off frequency. <IMAGE>
