Patent DE-2237170-A1 (DE)
Title: Fluidized bed heat exchanger - for efficient purificn of gases
Inventor: LINNEBORN HANS DIPL ING
IPC: F23G7/06
Filed: 1972-07-28
Abstract: The heat exchanger features a combustion chamber to which is attached an inlet for the gases to be purified and a blower for the supply of air. The gases are heated to a desired temp. in the combustion chamber and pass through a central tube into the fluidized bed consisting of small spheres of inert materials e.g. glass, porcelain etc. The central tube forms the inner boundary surface of the fluidized bed. The high fluidization velocity and the disintegration caused thereby of the limiting layer in the fluidized bed causes a higher heat transfer which aids making the impurities harmless. The purified gas is either let out to atmosphere or made use of in further processing units, e.g. filters, coolers, absorbers etc.

Title: Side-discharge tracked bucket excavator - twin buckets on transverse slide sideways under hydraulic pressure
Inventor: MATZEN UWE
IPC: E02F3/40
Filed: 1973-12-21
Abstract: Side discharge bucket excavator consists of two buckets (1) on a transverse rotating arm (2). The buckets are guided in identical slots (7) by pivots (8). When the buckets have been filled, they slide to the sides and the soil is discharged to the right and left of the excavator instead of behind. This is achieved by means of a hydraulic cylinder (3) mounted between the pivot of each bucket and the pivot of the transverse arm, thus making the bucket move towards the outside until each bucket pivot reaches the end of its slot. Each bucket cannot be pivoted to empty out contents until the end of the slot is reached.

Title: Cylinder lock door mounting - is protected against breaking-in by hardened insets inside door plates
Inventor: HUEBNER ROLF
IPC: E05B15/16
Filed: 1974-05-13
Abstract: Cylinder locks fitted in door plates can be relatively easily burgled by drilling around the cylinder perimeter and removing the cylinder. The inset plates cast into the outer lock plate and made of hardened material prevent this partly by offering a considerable resistance to drilling by the hardness of the material and partly by being provided on the outside face with a number of humps with tapered sides and arranged in such a way that the drill bit, after having penetrated the outer skin of the door plate tends to slip-off without being able to bite into the material of the hardened inset. Apart from this the surround of the cylinder lock in the door plate is made in the shape of a sturdy shoulder.

Title: Thermostatically controlled flow valve - has two way spool biased to regulate hot and cold water supplies
Inventor: BANKSTAHL NORBERT
IPC: G05D23/13
Filed: 1974-07-11
Abstract: A thermostatically controlled flow valve regulates output flow temperature by mixing hot and cold water and discharges flow back to the boiler when the reference is attained. The boiler is supplied with cold water and transfers hot water to the inlet of a mixing valve. The mixing valve combines hot and cold water supplies dependent upon the setting of the thermostat controlled by a knob. Outlet flow at the required temperature is transmitted to output loads. Return flow is passed through the valve and is combined with flow from the mixing process before returning to the boiler. The thermostat element in the valve moves a two way spool against a spring bias to regulate inlet flows.
