Patent DE-2501150-A1 (DE)
Title: Eccentric press device with releasable coupling of piston rod and stam - has compressed medium interflow driven by plunger piston and which ceases during stamp upward movement
Inventor: SCHUSTER GERHARD
IPC: B30B1/26
Filed: 1975-01-14
Abstract: An eccentric press is constructed such that it has a releasable coupling between the piston rod and the stamp. The coupling element is a push rod having a band or tie and acts as a plunger piston. This plunger piston compresses a medium from one space into another space during stand-still of the stamp during the upward motion of the system. The compressed medium is then fed back into the first space (9) during the stamp upstroke by means of which the connection between the spaces is broken to move the stamp (4) upwards. The upward movement results from the contact of the band or tie with a muff or sleeve connected to the stamp.

Title: Solar energy collector for house roof - has large number of mirror plates reflecting radiation onto common collector
Inventor: RADONS ULRICH ING GRAD
IPC: F24S23/77
Filed: 1975-03-18
Abstract: The collector is mounted on a south facing sloping roof. It is built from a large number of rectangular reflecting mirrors (2) which are placed between the roof joists (1). Each mirror is mounted on a lever arm (3) and all the arms are moved together from a motor (4) in unison with the movement of the sun. They are arranged to reflect incident radiation onto a collector tube (7) through which water is circulated. The energy from all the reflectors is concentrated on a single collector which is thus raised to a higher temperature and occupies less space than a collector receiving radiation directly. The tilting of the mirrors ensures that radiation is concentrated on the same spot at all times of day.

Title: Steam condensation by blowdown into water as small bubbles - created by water sucked into steam flow by ejector effect
IPC: F28B3/06
Filed: 1975-03-18
Abstract: A nozzle for the direct condensation of steam or steam-air mixtures comprises a dip-pipe immersed in water (b) and possessing >=2(3, 4 or more) narrow outlet openings, these produce a corresponding number of separate streams of small bubbles having a large total surface area, the bubbles being produced by an injector effect as the steam flow (downwards) sucks in water (horizontal arrows) from around the pipe. The method is used in process technology and in pressure-reducing systems in nuclear installations. By avoiding large exit areas, the tendency to form a large steam bubble followed by collapse and an inflow of water is reduced. This reduces shock loading. The blowdown system is well adapted to a wide range of steam flows.

Title: Flamed pralines from marzipan and chopped roasted almonds - mechanically moulded to simulate hand made Bethmannchen pralines
Inventor: STIEL DIETRICH
IPC: A23G3/48
Filed: 1975-05-22
Abstract: Prodn. of flamed pralines from marzipan and almonds is improved in that a mixt. contg. marzipan and chopped roasted almonds in mechanically moulded to form comes with three almond-like side protrusions, and the cones are browned in a flame furnace. The mixt. pref. contains (in pts. wt.): raw marzipan preparation 10, icing sugar 1-3, and chopped roasted almonds 1-3. The pralines can be glazed in the conventional manner. The pralines obtd. have the shape of Bethmannchen pralines (RTM) which, however, cannot be shaped mechanically as a whole almond's or halves must be manually inserted into a marzipan cone. Thus, the cost of the prodn. of the original Bethmannchen is high, whereas the mechanical shaping of the pralines as described above is much cheaper. Moreover, the use of chopped roasted almonds improves the taste of the product.
