Patent DE-2264744-A1 (DE)
Title: Underwater trench digger with pulsating pressure jets - has hydraulically operated water supply valve
IPC: E02F5/10
Filed: 1972-05-17
Abstract: The valve head is supported in a bracket co-axially with the nozzle. The valve body houses a spring which normally keeps the valve open. The upper end of the valve body is linked by a bell crank lever to the piston rod of a hydraulic ram mounted on a pivot. By supplying fluid at pressure to the ram the valve can be opened or closed, thus controlling the volumetric flow and velocity of the jet to suit varying conditions of excavation. Rapid motion of the ram gives a pulsating flow when required, by difficult excavating conditions.

Patent DE-2413250-A1 (DE)
Title: Heat exchanger for e.g. recuperative oven - contains wire mesh inserts in tubes carrying heating gas to promote turbulence
Inventor: SCHMIDT THEODOR DR ING
IPC: F28F1/10
Filed: 1974-03-20
Abstract: The heat exchanger consists of concentric tubes forming a central cylindrical passage for the gas to be heated and an outer annular passage which is traversed by the heating gas in parallel flow or counter flow to the gas being heated. Heat transfer takes place by conduction through the intermediate cylindrical wall between the two spaces. An insert is placed in the outer annular passage. The insert consists of a metal gauze or wire mesh arranged in a helical or concertina like spiral. It has the effect of promoting local turbulence and thereby increasing the rate of heat transfer which in turn reduces the metal temperature of the intermediate dividing wall between the two gases.
Patent DE-2415586-A1 (DE)
Title: Sinter-granulation and heat treatment of solid particles - in fluidised beds with countercurrent flow of solids
Inventor: STEFFEN EGBERT DIPL ING
IPC: B01J8/00
Filed: 1974-03-30
Abstract: In the granulation by sintering (followed by subsequent heat treatment where appropriate) of the solid particles in a fluidised bed, in which the product is extracted through orifices in the bed distributor plate, the product is extracted through the orifices provided for the inlet of the fluidising gas. The orifices are sized according to the required size of the product particles, which flow out in a direction opposite to that of the fluidising gas. Used in cement mfr. and similar processes. The temp. and residence time of the particles can be accurately controlled. Very finely powdered material can be processed, since the particles remain in the bed until the required degree of agglomeration has been achieved. In cement production, strongly alkaline raw material can be processed.

Title: Hydraulic seat mounting for smooth adjustment - fitted with spring loaded safety valves for absorbing impact forces
Inventor: RUEHMANN BERNHARD
IPC: A47C1/024
Filed: 1974-04-01
Abstract: The seat position is adjusted by releasing the shut-off valve in the hydraulic piston of the damper fitted between the seat mounting and the floor. A further connecting line between the two sides of the piston takes the form of a restricted flow line with a pressure sensitive valve. This valve opens when the pressure difference across the piston exceeds a set value, i.e. during a collision. The damper then acts as a shock absorber, without elastic spring back. For normal use the hydraulic cylinder enables a fine adjustment to be achieved for the seat position.
