Patent EP-0309728-A2 (EP)
Inventor: BERTHOLD HEINZ
IPC: F01B3/00
Filed: 1988-08-22
Abstract: In a piston (1) for axial-piston engines, the piston (1) being designed as a hollow body with an axial cut-out (2), on whose circumferential wall there are arranged at least two annular shoulder surfaces (6), which run in the circumferential direction, face away from one another and are spaced apart from one another, and which engage with light-alloy material (4) cast into the cut-out (2), it is intended to improve the attachment of the light-alloy material (4) in the hollow body, while ensuring a simple design. This is achieved by the shoulder surfaces (6) extending essentially at right angles to the longitudinal axis (7) of the piston (1), and by the light-alloy material (4) being clamped in a force-fit manner onto the shoulder surfaces (6), with shrinkage. <IMAGE>

Abstract: A connector between tube parts (2, 3) which enables the parts to be connected easily and reliably is specified for rods, especially for a diamond core bit with tubular part and threaded connection. The connector contains an extension (8) with slots (12) for one tube part and an extension part (35) with projections, pins or the like (11), which project beyond the extension part (35), for the other respective tube part. Upon connection, the projections (11) engage in the slots (12). The extension part (35) fits into the tubular opening of the extension (8) and, to provide a special seal on its outside, has a groove (17) with an O-ring (16) inserted in it. A clamping ring (25) is rotatably mounted on the tube part (3) with the projections (11). One end wall (14) of the clamping ring (25) is supported in a sealing manner against an end wall (9) of the extension (8). As a result, the projections (11) are clamped in place in the slots (12) and at the same time the tube parts (8, 3) are firmly connected to one another. The connector parts containing the clamping surfaces, in particular the clamping ring and the extension provided with slots, are made of plastic. In the area of its end wall, the extension has projections (91), e.g. an encircling crest (91). In the area of its corresponding end face (14), the clamping ring (25) is formed at its inner wall in such a way that, upon connection, its inner wall encloses the projections (91) from outside and limits their deformation. This also enables flexible materials to be used. <IMAGE>

IPC: B65D51/20
Filed: 1988-11-14
Abstract: A pour spout construction particularly adapted for longer shelf life barrier paperboard containers, such as containers of the gable top type. Barrier containers often carry products and the interior surfaces of the former are lined or covered with a barrier layer (34). According to this invention a dispensing opening (30) is formed in the paperboard (21) and the major barrier layer extends across and covers this opening. An externally threaded pour spout (40), attached to the container, carries a threaded cap (52, 54, 60) which normally closes the pour spout. This cap carries an innermost annular skirt (60) whose lower edge is adhered to that barrier layer portion which spans the dispensing opening. When the cap is unscrewed from the spout, the innermost annular skirt carries a part of the barrier layer away from its normal, sealing position, thus rupturing the barrier layer and permitting dispensing of the container contents.

Abstract: High speed readout is achieved in a triangulation ranger by a coded aperture light detector (17) which provides a direct digital representation of the range or height of a surface (12) from the ranger. A light spot (19) reflected from the surface (12) is optically spread (20) into a line segment (21) so it can be shared among a number of light detection channels (26-1 to 26-4). The line of light falls on a coded aperture (26) in front of a segmented fiber optic bundle (28-1 to 28-4) and the light transmitted by each channel is led to a separate photomultiplier or solid state detector (29-1 to 29-4). Every coded channel (26-1 to 26-3) is constructed to give one bit of the digital address of the range position, and a reference light value is obtained from another channel (26-4). Background and secondary reflections may be filtered out by focusing light scattered from the surface to a spot and passing it through a slit aperture (45, Fig. 8) oriented in the plane of triangulation before being spread to a line segment.

Abstract: According to an illustrative example a gas spring comprises a cylinder (10) and a piston rod (11) axially movable with respect to the cylinder. The piston rod is guided through a guiding and sealing ring (13) adjacent one end of the cylinder. A piston (12) is fastened within the cylinder with the inner end of the piston rod. The piston is provided with an axial passage (20) connecting the two working chambers on both sides of the piston. A pressurized gas is provided within both working chambers. One of the working chambers is connected with a pressure reservoir (2). The pressure of gas within the pressure reservoir is larger than the pressure within the working chambers. A shut-off valve (5) is pro­vided between the pressure reservoir and the respective working chamber. This shut-off valve is automatically controlled such as to admit pressurized gas from the reservoir to the respective chamber when the pressure value within the respective working chamber falls below a predetermined pressure value. The shut-off valve is closed again when the pressure within the respective   working chamber has risen again up to a determined pressure value. Such it is warranted that the pressure within the working chambers does not fall below the predetermined value as long as the increased pressure within the reservoir exists.

Abstract: A method for estimating vehicle reference speed and acceleration utilising an adaptive filter for providing periodically updated reference values given by a currently extrapolated value plus a correction term which is a function of current wheel slip, wheel acceleration and wheel velocity. The method may be successfully employed over a wide range of road friction coefficients and may be used for traction control as well as anti-skid braking, since the approach does not assure a fixed limiting wheel acceleration. The method avoids the necessity of maintaining low slip values on preselected wheels in order to obtain suitable reference speed values.

Abstract: The invention describes a method and arrangements for connecting a new cast strand to a preceding strand during continuous casting in a continuous casting plant. …<??>The continuous casting plant has a tundish with a closeable outflow opening. Arranged underneath the outflow opening is a cooled continuous casting mould in which the connection of the new cast strand takes place. The method for connecting two cast strands in a continuous casting mould in the case of a change of charge makes it necessary to close the mould outlet briefly, this being achieved by opening the mould outlet, casting a strand, attaching connecting means to the end of the strand and connecting the leading end of the new strand to the connecting means for the purpose of further processing the two strands jointly. As connecting means, the arrangements for connecting either a cold strand or a preceding, still hot cast strand use a stub tube-like body which, in the simplest case, comprises a tube whose cross-section is geometrically similar to the cross-section of the mould. A frictional connection is formed in this tubular body due to the shrinking on of the strand shell as it cools. …<IMAGE>…

Abstract: A two-channel error-tolerant clock generator arrangement contains two clock generators (TG1, TG2) which in each case contain an oscillator (Q1, Q2). The frequency of the oscillator of one clock generator (TG1) is lower than that of the other synchronised clock generator (TG2). The latter compares the phase difference between its output signal and that of the other one. If the phase difference exceeds a predetermined amount, a pulse is gated out of the output signal of the oscillator (Q2). The invention is used in redundant process control systems. <IMAGE>
