Patent DE-3400232-A1 (DE)
Title: Apparatus for refuse comminution in large plants
Inventor: SCHWARZ WERNER
IPC: B02C23/02
Filed: 1984-01-05
Abstract: A slide unit 14 is fitted to one sidewall 13 of the supply hopper 11 of the apparatus, and its slider ram 16 can travel out towards the comminution unit 12. Bridges which hinder throughput are thereby overcome. Several blocking slides 18 are guided on the opposite sidewall 17 and can be pushed from outside into the inner space of the feed hopper 11. They form a barrier for the refuse situated above, so that a flap 23 in the sidewall 13 can then be opened. Refuse parts which cannot be processed by the comminution unit 12 are thereafter ejected to the side through this flap 23 by means of several ejector rods 22, these ejector rods being pushed in from outside through the gaps between the cutter discs on the feed side. The apparatus thus has a substantially higher throughput, and interruptions can be eliminated with a very small time penalty. <IMAGE>

Inventor: EWALD HANS
IPC: B60B30/06
Filed: 1985-02-13
Abstract: A method and apparatus for mounting pneumatic vehicle tires, the beads of which have pull and compression resistant bead cores, with the beads, in the mounted state of the tire, being disposed on the radially inner periphery of a wheel rim next to the essentially radially inwardly extending rim flanges of the latter. A mounting mechanism is brought into contact with the peripheral region of a tire bead portion that has been introduced into the rim. The mounting mechanism is introduced in such a way that a first section of the mounting mechanism rests against the tire axially outwardly of the rim flange, while a second section of the mounting mechanism rests against the tire at the level of the rim flange and/or axially inwardly of the rim flange. These two sections of the mounting mechanism define an angle of 80 DEG  to 120 DEG  relative to one another. While the introduced tire bead portion is held in place against the rim, the mounting mechanism is guided along the periphery of the tire. After the tire and rim have been turned over, the procedure is repeated for the other bead of the tire.

Patent DE-3525933-A1 (DE)
Title: Spiral compressor
Inventor: VESS KLAUS DIPL ING
IPC: F04C18/02
Filed: 1985-07-19
Abstract: Using spiral compressors for compressible media and liquids, which compressors have a wrapping angle of at most approximately 540 DEG , only a relatively low compression pressure can be achieved. In the case of spiral compressors whose generator poles associated with the individual spiral courses are at a distance from one another, considerable torques are exerted on the compressors. So as to largely eliminate said torques and to increase the compression pressure, it is proposed according to the invention to design a spiral compressor in such a way that at least two intermeshing external spiral-shaped pumping ducts, which have a wrapping angle of at least 360 DEG , communicate with at least one internal spiral-shaped pumping duct having a wrapping angle of at least 360 DEG . <IMAGE>

Patent DE-3531469-A1 (DE)
Title: Steam engine
Inventor: MUNZINGER FRIEDRICH
IPC: F01C1/352
Filed: 1985-09-03
Abstract: In a steam engine with at least one first planetary rotation machine operated for expansion of superheated steam into saturated steam and at least one second planetary rotation machine operated for compression of wet steam into saturated steam, the pistons of which are drive-connected to a common machine shaft in a tandem arrangement, a condenser provided for changing the state of the saturated steam into a further dry phase of the wet steam is formed by a plurality of jointly cooled nozzles, each designed in the nature of a Laval nozzle, through which the saturated steam flows parallel to the axis. The nozzles cause a lowering of the pressure level of the steam flow and conversely an increase of the rate of flow in order to reduce the oscillation energy of the steam molecules only to such a degree that no formation of condensate droplets occurs.
Patent DE-3535430-A1 (DE)
Title: Plant for recovering energy from flowing water
Inventor: RADEBOLD CLAUS
IPC: F03B9/00
Filed: 1985-10-04
Abstract: By means of the plant for recovering energy from flowing water, which plant acts as a hydroelectric power station, the flow energy is utilized in that the, usually two-blade, web is installed underneath the surface of the water in the flow of a river. The blades are mounted so as to be rotatable and capable of moving upwards and downwards in order to be able to assume the respective most favourable position for example for high water, low water, the formation of ice etc., under either automatic or manual control. The flow energy is utilized in that rotating rotor blades are folded out at the upper end of the machine all around in the individual vanes at short distances one behind the other, the said machine facing the flow, as a result of which they are moved along the longitudinal side of the machine driven by the flow in order to be folded together and moved back behind a wall into the initial position required for the folding out, as a result of which only a small expenditure of energy is produced. Under appropriate flow conditions, an excess of energy is produced with each complete rotation of the rotor blades.

Title: Firing of submunitions
Inventor: DUNN ALBERT
IPC: F42B12/62
Filed: 1985-11-25
Abstract: Submunitions (11) are catapulted forwards out of a carrier projectile (10) when a rocket motor (12) in the carrier projectile is no longer accelerating the submunitions. A catapulting force is produced on a piston head (43) by means of the pressure of gases from the rocket motor and acts on rear surfaces (26) of the submunitions, and becomes so great that it shears shear pins (34) which connect the submunitions to the carrier projectile, but only when the reaction forces of the submunitions (11) on the piston (43) decay as a result of the acceleration. The submunitions are preferably moved outwards from the carrier projectile at the time of separation, preferably by rotation of the load-bearing structure of the submunitions about the longitudinal axis of the carrier projectile. <IMAGE>
