Title: Apparatus for continuously shaping the wall of a pipeline of thermoplastic material
IPC: B29C33/20
Filed: 1988-03-30
Granted: 1989-04-27
Abstract: In an apparatus for continuously shaping the wall of pipes of thermoplastic material by means of a travelling hollow mould, which is made up of successive pairs of mould halves respectively at the beginning of the hollow mould, the two mould halves at the beginning of the hollow mould are connected rigidly to each other by means of safety bolts.

Title: Method for the electronic, force-controlled, computer-assisted recording of the depth of gingival pockets
IPC: A61C19/04
Filed: 1988-07-16
Granted: 1989-10-26
Abstract: For diagnosing disorders of the periodontium (periodontopathies), determination of the depth of gingival pockets is necessary. This is to be effected in a force-controlled fashion by the probing process without reading-off a scale or adjusting a reference point. The measured value is to be made available directly for further data processing. On probing of the gingival pocket the measurement process is triggered by an electronic control logic when a predetermined force level is reached. Depending on the penetration depth of a probe tube a different number of outflow openings of a probe tube are covered by the gums, so that a gaseous or liquid medium which escapes under a slightly superatmospheric pressure from the outflow openings is counteracted by a different flow resistance which is indirectly determined with a pressure sensor in the media-supplying system. The measured value of the pressure sensor is processed in an electronic circuit such that it can be transferred via an interface to a personal computer. Diagnosis of periodontopathies and check of the success of dental treatment measures.

Title: Regenerative braking arrangement for electronically regulated motor - modulates transverse control DC of three bridge circuits carrying control AC
IPC: H02P3/18
Filed: 1989-11-21
Granted: 1991-07-04
Abstract: The arrangement is for feedback into the public three-phase a.c. mains of the electrical energy available as d.c. in an intermediate store and resulting from regenerative braking of electronically controlled three-phase a.c. motors. As an example, one bridge circuit is given, three are used in a practical circuit design, and a control a.c. voltage (Us) of 12V is applied to the horizontal inputs of the bridge circuit (R1, R2, D1, D2). The positive half-wave (Iw1) flows across the resistor (R1) and the diode (D1), while the negative half-wave (Iw2) flows across resistor (R2) and diode (D2). The vertical terminals of the bridge circuit are the d.c. voltage terminals. ADVANTAGE - Provides safe and reliable electro-energy recuperation, even during negative half-waves of a.c. voltage.

Granted: 1992-07-16
Abstract: An intra-ocular artificial lens for replacing the lens of the eye has a lens body (2) arranged in the posterior chamber (15) of the eye and preferably two substantially spiral haptic fasteners (4) secured to the lens body. The haptic fasteners go from the posterior chamber (15) into the anterior chamber (13) of the eye over a through-section (18) that extends perpendicularly or angularly to the iris (9) each through a peripheral iridectomy (12). In the posterior chamber (13), they are supported by an anterior chamber section (19) on the surface of the iris or in the angle (14) of the anterior chamber. Their support in the anterior chamber ensures that the lens is reliably attached. In addition, the lens can be supported in the Sulcus ciliaris (5) by means of a supporting segment of the posterior chamber section (17), so that the lens is reliably supported in both chamber. Also disclosed is a process for producing this lens, according to which the haptic fasteners are first formed with all their three sections on a plane, for example by cutting, then the sections take their working positions at least by deformation by rotation of the through-section.

Granted: 1995-10-19
Abstract: In a furnace the pressure P1 at the end of a zone B (a firing zone) and the pressure P2 at the beginning of an adjacent zone K (a cooling zone) are measured. These measured pressures are used to control an extractor 20, 24, 26 (located in the vicinity of the point at which the second pressure is measured) and so the pressure at the beginning of the zone K. When the ratio P1:P2 is less than 1 valve 26 is opened up by motor 24 to reduce the value of P2. When the ratio P1:P2 is greater than 1 the valve 26 is shut down by motor 24. A second extractor 38, 40, 42 may be provided. The measured pressures are fed to a computer 18 which in turn controls the extraction. Gas is supplied to the furnace by a supplier 28, 30, 32 remote from the point at which P2 is measured, and is controlled in accordance with signal from a temperature sensor 34. <IMAGE>
