Patent DE-4028595-A1 (DE)
Inventor: BARTELS ROBERT-JAN DR ING
IPC: B25D9/26
Filed: 1990-09-08
Abstract: The object of the invention is to configure a percussion mechanism in such a way that the number of blows - and hence the return stroke and the individual impact energy of the percussion piston - is matched automatically to changing working conditions via an internal control system as a function of the contact pressure on the tool insertion end. 
<??>For this purpose the invention proposes to hold a contact-pressure control element (31) at least temporarily in contact with the insertion end (12) under the action of a resetting arrangement (31a, 22) acting in the striking direction (arrow 18) and, via this contact-pressure control element, to connect a control conduit (35) either to a pressure conduit (22) or to a balanced return conduit (25). 
<??>Via the control conduit, a switching element (30) can be actuated in such a way that the control device (4) alternately switching over the movement of the piston performs the reversing movement into the working-stroke position at an earlier or later point in time during the return stroke (arrow 19) of the percussion piston, thereby triggering the working stroke of the percussion piston in the striking direction.

Title: Plasticising unit for injection moulding machine
Inventor: HEHL KARL
IPC: B29C45/20
Filed: 1990-11-02
Abstract: Molten polymer is conveyed into the area in front of the screw and then forced by axial screw movement into a tool. Back flow of the polymer is prevented by a non-return valve which creates a high pressure zone in front and a lower pressure behind the valve. The plasticizing barrel comprises two parts, namely a barrel head which always and completely encloses the non-return valve and the high pressure zone and also a barrel which surrounds the screw and the low pressure zone. Even when the screw is in the farthest retracted position the joint between the barrel and the barrel head always lies within the low pressure zone.

Inventor: MARTIN JOHANNES DIPL ING
IPC: B01D53/58
Filed: 1990-11-08
Abstract: In the process for separating ammonia from gases, in particular exhaust gases from combustion processes, in which ammonia is formed or released, or in which ammonia or a substance forming ammonia under the action of heat is fed, a material from the group of the zeolites is added to the gas to be purified as a treatment medium in fine distribution, with good mixing with the gas. The added compounds here have the advantage that they not only remove the ammonia very effectively from the exhaust gases by adsorption but can also bind it very firmly in their internal structure, whereby renewed release of ammonia in permanent storage is avoided.

Filed: 1991-03-27
Abstract: A method and apparatus useful in the course of a milking operation in which the milk is intermittently conveyed in the form of separate milk slugs, to accurately determine the mass of the individual milk slugs and to thereby determine the actual milk flow rate. A measuring apparatus of this type is particularly suitable for use as an indicator operable to indicate a drop in the milk flow to below a predetermined value at the end of a milking cycle. An additional operation of measuring the travel speed of the individual milk slugs results in an extremely simple milk flow measuring device being obtained, which is capable of relatively accurately measuring the milk flow rate throughout the milking cycle.
