Title: Connection member for pipe ends
Inventor: HUESSELMANN WILHELM
IPC: F16L47/24
Filed: 1987-03-07
Abstract: The invention relates to a connection member for the sealed connection of one end of a pipe consisting of plastic, preferably of high-density polyethylene (HDPE), to one end of a pipe consisting of metal, preferably steel. In order to provide a connection member of the abovementioned type which is not only easy to produce and relatively rapid to mount, but also has a desired long-term sealing capacity, the invention proposes that said member be composed of an outer bush (1) and an inner pressing bush (2) which is arranged coaxially with respect to said outer bush, an annular space (3) being left between the outer peripheral surface of the inner bush (2) and the inner peripheral surface of the outer bush (1), which annular space serves to receive the connection end (4) of the plastic pipe (5) with a press fit. In its inner peripheral surface, the outer bush (1) exhibits a plurality of annular grooves (6) in the manner of a toothing arrangement. In its inner peripheral surface, the outer bush (1) is provided at least with one annular groove (7) in which an O-ring (8) is located. <IMAGE>

Title: Device for conversion of heat energy
Inventor: HOEVECKE WILHELM
IPC: F02G1/044
Filed: 1987-07-15
Abstract: The device for conversion of heat energy into mechanical work or into electrical or storable energy exhibits at least two heat reservoirs at different temperatures, each with a liquid medium and at least one heat exchanger. Arranged downstream of each heat reservoir is a device with a heat exchanger and with a piston displaceable under the pressure of an enclosed amount of gas, which device moreover is arranged in a closed hydraulic circuit with a hydraulic motor. The heat reservoir with the higher temperature alternatingly supplies heat to the devices, and the heat reservoir with the lower temperature alternatingly removes heat from the devices, the hydraulic motor producing work. The piston rods can also be directed towards the outside, exhibit a piston of ferromagnetic material, and in each case work together with a coil according to the immersion coil principle. A heat pump is also arranged between the two heat reservoirs. The heat reservoir with the higher temperature can be in radiation contact with the sun, in heat-conducting contact with waste water or used water giving off heat, and/or in radiation contact with a device giving off waste heat. An electric generator can be connected downstream of the hydraulic motor, and a device for electrolysis of water and a hydrogen reservoir can be connected downstream of the generator.

Title: Method for the production of sand cores for hollow ceramic parts
Inventor: EIGENFELD KLAUS DR ING
IPC: B22C9/10
Filed: 1987-07-31
Abstract: The invention relates to the production of the sand cores for hollow ceramic parts, which are held during the casting of the finished part in the casting mould. To avoid longitudinal cracks in the ceramic part due to the internal pressure in the mould during core production, the invention proposes to support the ceramic part in the core box via rubber-elastic material. In this arrangement, the rubber-elastic material exerts an external pressure on the hollow ceramic part which is at least equal to the internal pressure in the mould exerted during sand core production.

IPC: H03B5/36
Filed: 1987-09-12
Abstract: The described radio-frequency generator contains a crystal oscillator in a Clapp circuit (CO) in which a first transistor (T1) is coupled via a connection of its base and of its emitter to a first parallel tuned circuit (Q, C2, C3, C4). In order to obtain an oscillation of high spectral purity without any additional amplifier stage, it is provided that the collector of the first transistor (T1) is connected via a second parallel tuned circuit (L, C6) to one pole (+UB) of a supply voltage source, and that the second parallel tuned circuit (L, C6) is tuned to the nominal frequency of the first parallel tuned circuit (Q, C2, C3, C4). On the basis of such a sinusoidal oscillator (sine-wave oscillator), a radio-frequency clock generator can be specified which uses only one further transistor amplifier stage and whose clock has a 0.5 duty ratio. <IMAGE>

Inventor: HEICHLER JOHANNES DIPL ING
IPC: H04B14/02
Filed: 1988-02-15
Abstract: In a method and device for regenerating a PPM signal, an analog/digital conversion is carried out for each time slot and the resulting digital value corresponding to the amplitude is stored separately for each time slot, the values of each amplitude stage of the n stored values are logically combined with one another and in this way the digital value for the maximum amplitude is determined, the value for the maximum amplitude thus obtained is compared with the values for each of the n time slots and, if the value for the maximum amplitude coincides with the value of the amplitude for the time slot which has just been compared, a signal is emitted. <IMAGE>
Patent DE-3809514-A1 (DE)
Inventor: SCHMIDT THOMAS
IPC: F16J15/3204
Filed: 1988-03-22
Abstract: The means consists of a cylinder 10 having a drive piston 11 therein and a pressure store connected to the cylinder chamber 13, the drive piston 11 being connected to a cable 12 for transmitting displacement of the piston to the belt reeling means. The cable passes through the piston and is fixed thereto, at an end portion projecting from the piston, by means of a metal clamp 15. The piston 11 consists of a deformable plastics material and closes off the cylinder chamber 13 by forming a seal against the cable 12 passing therethrough. This sealing action is assisted by the cooperating tapers 16, 17 on the piston and clamp. The arrangement reduces the leakages in the piston area and at the same time simplifies the manufacture of the piston and cylinder. The piston may have a sealing lip at its lower end which is spread outwardly by the pressure in use against the cylinder (Fig 2) or which is trimmed by the metal cylinder wall to provide a close fit (Fig 3) or which instead cuts a sealing path into a plastics lined cylinder. <IMAGE>

IPC: A23L5/30
Filed: 1988-10-24
Abstract: The object was to create a device for improved application techniques for treatments using high-frequency oscillators with a predetermined frequency ratio of 2:3. The electrodes that have hitherto been conventional in this context are antenna electrodes without connection to reflectors. Tests have demonstrated that improved direction, metering, simpler operation and more favourable therapeutic use of the double-field energy are possible via the free antenna ends of the oscillators in conjunction with reflectors. The solution proposed by the invention is to provide the two free antenna ends of two high-frequency oscillators (4, 5) with a predetermined frequency ratio of 2:3 with an arrangement of elements (6, 7) connected to a reflector (8). The special applications for the invention are: medicine, water hygiene and foodstuffs technology. <IMAGE>

Title: Method and arrangement for utilising lamps which are no longer functional
Inventor: MAIER DIETER PROF DR ING
IPC: B03B9/06
Filed: 1988-12-20
Abstract: In the method according to the invention and in the arrangements for implementing the method, fluorescent lamps are surrounded at their ends by closed working containers and are thus closed off from the environment. Subsequently, the lamp ends are separated and the fluorescent coating and other materials contained as well as harmful substances are removed from the lamp body. By separating all components, these can then be supplied for recycling. As a result of the sealed encapsulation of all work processes in the working containers, no harmful substances, in particular no mercury, is given off into the environment in the utilisation method according to the invention.
