Abstract: The invention relates to a piston (1), comprising a ring carrier (2) and a glass piston (3) for observing processes in a combustion chamber (B) of an internal combustion engine, wherein the glass piston (3) is placed upon the ring carrier (2) and is securely connected thereto in the region of an inner casing surface (8) of the ring carrier (2). In order to avoid overly high heat strain in the glass piston (3), the glass piston (3) is connected to the ring carrier (2) via at least one form-fit connection (20), and preferably via a force-fit connection (30).

Abstract: An automobile door lock having a lock mechanism, with a variety of levers, and lock elements, like a ratchet (1) and a pawl (2), whereby the lock mechanism has an outer actuation lever (6), cooperating with an operating surface (4) of an outer door handle (5), and a clutch lever (9), cooperating with an outer actuating lever (6). Between the levers, there is provided a bolt connection assembly (12) with a longitudinal slot (13), a retaining bolt (14), and a bias spring (15). With the retaining bolt (14) loosened, the outer actuating lever (6) is moved by means of the bias spring (15), until it contacts the operating surface (4). With retaining bolt (14) tightened, both levers are firmly connected to form a unit which is adjustable by the outer door handle (5).

Abstract: A combined shipping and optionally presentation package for holding flatly packed goods or flat containers. This package possesses at least two presentation trays (3 ) holding the plastic containers (24), a slipover cover (2) with two opposite downward extending sides (9a, 9b) placed on the presentation trays (3) as well as means for holding the slipover cover on the presentation trays. Each of the presentation trays can have a long and a short flank (13, 17) and therefore be L-shaped in side view and be arranged standing in a row on the short flanks under the slipover cover.

Abstract: A portioning machine and a method for filling containers with food material is disclosed. The machine is particularly useful for meat products which are packed in plastic containers having a lip or edge, and prevents the food particles remaining on this lip and hence interfering with the sealing of the package. The machine has at least two filling stations and a pumping means to supply food material, each filling station is adapted to hold a container.
