Abstract: A multi-layered packing material in the form of a web for use in constructing blanks to be erected into finished packaging containers comprises a relatively stiff base layer made of paper, cardboard or foamed plastic coated preferably on both sides with a layer of thermoplastic material, e.g. polyethylene. The laminated packing material may also include aluminum foil to establish a gas-proof barrier. At least one of the edges of the laminated packing material is provided with a narrow edge zone of a heat-activatable bonding agent of the same thickness as the web such as a mixture of solid hydrocarbons which is mechanically stable but elastic at normal temperature and has a relatively low melting temperature range. The edge zone consisting of the heat-activatable bonding agent is utilized in establishing a butt type joint between it and an adjacent panel or other planar part of the container when erected.

Abstract: This invention is applicable to display systems, such as in a helmet mounted display or a head-up display, utilizing a holographic lens operating at a relatively large off-axis angle in order to perform the dual function of a combiner glass and an eyepiece. The holographic lens is used in conjunction with more conventional optical elements (lenses, mirrors and prisms) to present a high quality collimated virtual image of an object, such as the face of a cathode ray tube, to an observer. The aberrations inherent in a holographic lens constructed to operate at a large off-axis angle and with a large field of view are corrected both by constructing the holographic lens with aberrated wavefronts and by the optical elements used in conjunction with the holographic lens during playback. Some arrangements of the playback systems of the invention include a relay lens having cylindrical surfaces and tilted and/or decentered elements used to compensate for the axial astigmatism and axial coma in the holographic lens. The holographic lens is constructed with aberrated wavefronts primarily in order to correct a large assymetric variation of astigmatism across the field of view which arises because of a difference in tilt of the two image fields corresponding to the two mutually orthogonal line focal surfaces. The tilts of the two image fields are adjusted relative to one another in such a way that they may both be matched by a single tilt of the object surface.

Abstract: Each of the two separate resonance chambers (8, 9) of the fresh gas line is connected on the one hand to an expansion chamber (10) connected to the compressor (7) of the turbocharger and on the other to the assigned cylinders (1-3; 4-6). Resonance pipes (11, 12) run from opposing ends of the expansion chamber (10) to the more remote end of the respectively more remote resonance chamber (8, 9). Expansion chamber, resonance chambers and resonance pipes are of elongated design and run in the longitudinal direction of the engine. The resonance pipes (11, 12) may also run inside the expansion chamber (10) or the resonance chambers (8, 9). In this way known measures for dimensioning the resonance chamber capacity and the resonance pipe lengths in order to increase the fresh air charge of the cylinder are achieved with a space saving, so that an engine with such a fresh gas line can also be fitted in road motor vehicles. <IMAGE>

Abstract: The machine can work as a pump or a motor. In the first case, the fluid flows from the low-pressure side to the high-pressure side. In the second case it is the other way round. The pressure difference between high pressure and low pressure attempts to push the conveyor worm (1) towards the low-pressure side (65). In order to compensate for this axial thrust, the conveyor worm (1) is provided with a compensation piston (2). In addition there are frictional forces which act in an axial direction. In a motor these forces act in the same direction as the pressure force due to the pressure difference; in a pump they act in the opposite direction. In the case of the pump, the piston area should be chosen to be smaller, and in the case of the motor to be greater than would be required for pressure equalisation. So as not to have to provide the conveyor worm (1) with different pistons (for pump or motor mode), the free end of the piston is given a smaller area (6, d2) than would be required for pressure equalisation, said smaller area being acted upon by the pressure (65) which prevails at the other end of the conveyor worm (1). The piston (2) further has a second area (d1) which is acted upon by an intermediate pressure between the high pressure (67) and the low pressure (65). The sum of the smaller area (6, d2) and the second area (d1) is greater than the area which would be required for pressure equalisation. The intermediate pressure arises in a chamber (9) which is bounded by piston (2) and its bearing (3) and which communicates with the high pressure and low pressure side (67, 65) via leak points (64, 66). The throttle effect of these leak points changes as the piston (2) moves. <IMAGE>
