Title: Internal combustion engine with injection
Inventor: BRITSCH HEINZ DIPL ING
IPC: F02B23/10
Filed: 1981-07-18
Abstract: The internal combustion engine (2) has one injection nozzle (15, 25) per cylinder (4), which injects through an opening (14) in the wall (13) of the cylinder (4) in the direction of a cylinder head (3). The opening (14) is passed over by a piston capable of moving up and down in the cylinder (4) and is located at a distance of at least 30% of the lift height of the piston (5) from the top dead centre of an upper limiting edge (12). The injection nozzle (15, 25) injects fuel or coolant such as water and/or alcohol or the like in the direction of the cylinder head (3). Due to the large distance of the opening (14) from the top dead centre of the piston (5) the injection nozzle (15, 25) is protected for a long time from hot gases. The large distance also results in improved mixing of injected liquids with air or with gases to be cooled, the risk of lubricating oil dilution being at the same time reduced. <IMAGE>

Abstract: In a unit, consisting of a device (6) which can be inserted in an opening in a container (1), for example a bottle, for the meterable removal of contents from the container (1) and of a covering cap, in particular a screw cap (17), which interacts with said container, it is proposed, to improve the seal between the container interior and the outer surroundings, that the cap (17) has at least one sealing ring (21) which extends downwards from the inner underside of its upper termination (26), that the cap (17) has a step (20) with a diameter which corresponds to a mean diameter of a sloping surface (11) on a sealing flange (10) of the insert (6), and the sealing ring (21) has a diameter which corresponds to the inner diameter of the sealing flange (10) in such a way that, with the cap (17) mounted on the container (1), the step (20) exerts a sealing-force component perpendicular to the sloping surface (11) and the sealing ring (21) exerts a radial support force on an inner surface (12 or 28) of the sealing flange (10). According to a preferred exemplary embodiment, the sealing ring (21) consists of two sealing rings (21 and 22) which are separated by a gap (23). For the further improvement of the seal, the sealing ring (21 or 22) bearing against a dropping space (15) of the insert (6) has ribs (25) on its inner wall. To compensate for the differing diameters of the dropping channel (15), axially parallel longitudinal ribs (16) are expediently provided on the insert (6) so that the overall diameter remains constant and allows uniform caps (17) to be used. <IMAGE>

Title: Arrangement for testing contact lenses and progressive lenses
Inventor: DIETRICH KLAUS DR
IPC: G01M11/02
Filed: 1982-01-04
Abstract: The invention "arrangement for testing contact lenses and progressive lenses" describes a method for testing the material homogeneity and surface geometry of optical components. The method works according to the basic arrangement of Fig. 1. The test object (TL) is transilluminated by a wave front (WF) generated by the laser and expanded. The emerging wave front is transformed by means of the lens (FL1) into the Fourier plane (FE), multiplied there by an amplitude filter (AF), and transformed by means of the Fourier lens (FL2) into the image plane (BE). The amplitude filter consists of a large number of concentric, alternately transparent or opaque circles. There is then produced in the image plane (BE) an image of the test object on which is superimposed a system of alternately bright and dark curves. Each curve indicates for the test object sites with a constant gradient of the optical path length, from which the geometry of the test object can be determined. Typical applications:     - Determination of the lens centre point,   - Inspection of contact lenses,   - Inspection of progressive lenses.   <IMAGE>

Title: Metering device for emptying preferably plastic bottles with liquid contents
Inventor: LEPPAK WILHELM
IPC: B65D47/20
Filed: 1982-06-04
Abstract: The invention relates to a metering device for emptying preferably plastic bottles with liquid contents, which device can be fixedly connected to the actual liquid container, i.e. with the bottle or the canister or the like. In many areas (domestic, chemical, pharmaceutical and the like), it is necessary for particular liquids to be applied in a metered manner. The subject matter of the present invention is a metering receptacle which can be fixedly connected to the liquid container and can always remain on the container until the latter is completely empty. The special advantage of this metering device lies in the fact that this metering device according to the invention does not have to be screwed onto and unscrewed from the liquid container over again after the respective use, as in previously known metering devices, with the result that, once connected to the liquid container, it can remain thereon until the liquid container is completely empty. This metering device therefore offers the further advantage that, regardless of the dexterity of the user, an even, complete metering can always be undertaken, it also being ensured that hazardous liquids, in particular, such as corrosive liquids, cannot cause bodily injuries and material damages. This metering device cannot cause contamination because it is completely tightly sealed in itself. Handling is very simple and inevitable. Metering errors are ruled out. <IMAGE>
