Title: Multigear gearbox for motor vehicles
Inventor: FRIEDRICH KARL ING
IPC: F16H3/00
Filed: 1987-04-16
Abstract: In a multigear gearbox for motor vehicles immediately succeeding transmission gears (I-II, II-III, III-IV, IV-V, V-VI) are each respectively assigned to two different transmission ranges (1, 2). The input shafts (5, 6) of these transmission ranges (1, 2) are driven by means of two clutches (7, 8) shiftable under load, which are always operated simultaneously but alternately. In order to achieve a technical simplification and in order to make dimensioning of the two clutches, shiftable under load easier, two spur gear planetary transmissions (11, 12) are provided, which have a common planet carrier (13), which is rotationally fixed to the transmission drive shaft (14). The two sun gears (15, 16) of these planetary transmissions (11, 12) can be alternately braked by means of the two clutches (7, 8), shiftable under load, one clutch half of each of which is held so that it cannot rotate. The two internal gears (19, 20) are rotationally fixed to the input shafts (5, 6) of the two transmission ranges (1, 2). <IMAGE>
Patent DE-3715300-A1 (DE)
Inventor: GRAF LOTHAR
IPC: B65D47/34
Filed: 1987-05-08
Abstract: In a dispenser (1) for liquids, a section (39), which can be shortened by compression and thus serves for opening an outlet valve (15), of a piston shaft (11) which is associated with a piston unit (9), is protected against expansion in the original position and over a starting part of the pump stroke by means of a narrow rib routing and released in a part of the stroke subsequent to this starting part in such a way that it can be suddenly compressed by the pressure of the medium acting on the pump piston (10), as a result of which the outlet valve (15) then opens. However, at the start of this compression the section (39) which can be shortened carries out an idle motion after which it entrains the valve closing part (30) of the outlet valve (15) for the purpose of opening. Additionally, the outlet valve (15) can also be mechanically opened by a stop (14) at the end of the pump stroke. As a result, a particularly rapid dispensing of the medium as well as a simple evacuation of the air in the thrust piston pump (2) is made possible. <IMAGE>

Abstract: A cleaning solvent, e.g. trichlorotrifluoroethane, contaminated with chemical nerve agents, chemical blister agents, pesticides, toxins and/or biological agents is decontaminated by mixing with a neutralizing agent which is nonmiscible with the solvent to perform liquid/liquid extraction of the chemical nerve and blister agents present within the solvent. Any toxins or biological agents present in the solvent are rendered inert by the neutralizing agent. Particulate contaminants may then be filtered from the intermixed solvent and neutralizing agent at which point the solvent and neutralizing agent are allowed to separate. The resulting clean solvent exiting the separator is free of contamination and suitable for rouse in cleaning operations.
