Inventor: SCHULZ WOLFGANG
IPC: F02M25/08
Filed: 1998-07-28
Abstract: The invention relates to a device for testing the operability of a fuel system for an internal combustion engine with which the fuel vapors of a fuel tank are passed into an adsorption filter and into an induction pipe of the internal combustion engine via a tank ventilation valve or a regenerating valve, said ventilation or regenerating valve being able to be actuated between an opened position and a closed position.

Title: Concrete palisade for landscaping comprizes concave and matching convex sides plus straight sides as broken free line with convexly rounded palisade corners.
Inventor: ROTH REINER
IPC: E04C1/39
Filed: 1998-10-05
Abstract: The other side (2,3) of the concrete palisade should be straight in free or broken line so all corners (4) are interrupted at the same angle by the straight sides (2,3). The concave side of the palisade (5) is smaller than the convex side (6) and the remaining sector (9) up to the straight sides is formed by a convex sector (7) of the same radius and center as the main convex sector (6).

The palidade as such can be broken into several connected palisades with or without discard pieces, this giving rough break edges. The reinforcing steel stops short of the total palisade height to allow an upper discard or nonreinforced palisade part to be broken off to give the raw face.

Abstract: The lubrication system (1), for a number of lubricating points and especially at a knitter, has a distribution unit (7b) which is part of the pump unit (7a).  The cylinder (8) has a number of outlet channels, controlled by the piston (21). The cylinder (8) has a cylindrical wall, with the outlet channels passing through the wall. The piston (21) has at least one control channel at its mantle surface, which forms the distribution section (7b) by rotation of the piston (21) in alignment with at least one outlet channel, with the piston (21) rotating within the cylinder (8). The pump unit (7a) and the distribution unit (7b) are linked to a drive (33), which includes a rotating (55) and a sliding section both connected to the piston (21). The rotating section (55) has a setting motor, preferably as a step motor, to give the required rotary setting. The step motor is keyed to the piston (21) by a coupling with a fixed rotary play. The piston (21) has a locking unit (48) to give a keyed lock to the piston (21) to allow an axial movement in selected rotary positions, by acting on a locking wheel keyed to the piston. The lock (48) is moved in and out of contact with the piston locking wheel by a setting drive (51). The locking wheel is a ratchet wheel, and the lock (48) is a ratchet pawl. The sliding section is operated by the rotary drive (55), through a gearing which converts the relative rotary movement between the piston (21) and the rotary drive (55) into a piston (21) linear movement. The gearing has two threaded components where one is keyed to the piston (21) and the other is keyed to the rotary drive (55). At least one threaded component is connected to a magnet (62) to tense them against each other. A control sets the stroke movements of the piston (21). A sensor (66) monitors the piston (21) movements. An entry channel (12) leads into the cylinder (8), with the channels (5) linked to the outlet channels each with a non-return valve. An Independent claim is included for a lubricating action, to a number of lubrication points, with at least one pump. The lubricant is passed intermittently from the pump through the lubricating lines to the lubrication points, and the lines from the pump are subjected to variable pressures on a timed program. Preferred Features: The assembly gives a pressure modulated lubricating action. The lubricating operation contains a pressure pulse, which is a series of separate pulses with a pressure drop between them, which does not fall below the min. pressure level.
