Abstract: The spinal cannula 1 is provided with a grip part, which consists of transparent plastic and surrounds the rear end of the cannula in a substance-securing manner. A cerebrospinal fluid checking chamber, which tapers toward the rear end of the cannula and is visible from the outside, is located in it, and this cerebrospinal fluid checking chamber is joined on the rear side by a conical plug-type Luer bore for accommodating the Luer plug-type cone of a drug syringe in a positive-locking manner. On the outside, the grip part has, between two flange parts, at least two, radially recessed grip surfaces, which are arranged diametrically opposed to one another and symmetrically to a plane of symmetry located in the longitudinal axis, and between which the cerebrospinal fluid checking chamber is arranged. In addition, there is a stylet, which can be introduced into the cannula through the cerebrospinal fluid checking chamber.

Abstract: A device for vertically conveying coins including a lower horizontal guide path, a vertical guide path, an approximately arc-shaped deflecting path connecting the lower horizontal guide path and the vertical guide path. Each of the path conveys the coins in a lying fiat position. At least one conveyor belt is provided. Rollers are provided whereby the conveyor belt is led around the rollers. Deflecting rollers are arranged at space locations from the guide paths and the from the arc-shaped deflecting path. With this structure, an essentially constant conveying gap is formed by the thickness of the coins being conveyed between the guide paths and the deflecting paths and the conveyor belt. Structure for feeding the coins, conveyed lying flat one by one, is arranged at the beginning of the lower horizontal guide path. Structure for transferring the coins being conveyed is arranged at the top end of the vertical guide path.

Abstract: The present invention relates to a connector for high-speed networks of the voice and data transmission (CDDI connectors). The object of the present invention, namely to develop a CDDI connector with electrical properties which are improved and which guarantees that the requirements for high-speed network components are met, is achieved by the arrangement of the contacts on an inner and on a middle circle.

Abstract: A device for generating a test gas e.g., ethanol has at least two series-connected containers, which are filled with a calibration solution. A carrier gas, which is enriched with the calibration substance present in the solution corresponding to the vapor pressure of the calibration substance at the given temperature, is passed through these calibration containers. To prevent or to reduce the depletion of the components necessary for the gaseous calibration substance in the calibration solution, a defined amount of a stock solution is fed through the calibration containers in counterflow to the direction of delivery of the carrier gas.

Abstract: The process comprises the steps of creating three reference points at an object and taking a tomogram of the object such that the three reference points define a first set of positional data in the tomogram. The object is then non-rigidly placed on a support for operation thereupon by an instrument which is mounted at a flexible arm containing sensors for sensing the movements of an instrument tip. The instrument tip is placed at the three reference points in order to create a second set of positional data which are in a fixed relationship to the first set of positional data. When the instrument is inserted into the object placed on the support, the positional data of the instrument tip during the insertion movement are sensed and related to the first set of positional data via the fixed relationship between the first and second sets of positional data.

The terminal block includes a plastic casing and metal insulation displacement contact elements inserted pair-wise in at least two parallel rows into the casing with connected contact fingers forming spring contacts. The flat insulation displacement contact elements are formed at the narrow side webs including the contact slot therebetween and of the base web. The width of the spring contacts is small.

Abstract: The present invention pertains to a plain bearing for chassis parts in motor vehicles, in which a sliding layer, which is made of plastic and has lubrication bore reliefs on its outer jacket, is sprayed in a firmly adhering manner onto a metallic inner part in a mold, and an elastomer body arranged in a metallic receiving bush surrounds the inner part with the sliding layer in a slidingly movable manner. Recesses, whose side wall has a profile undercut in the direction of removal from the mold, are provided on the circumference of the inner part.

Abstract: A compliant mounting to attach a suction cup (11) to a support rod (10) is configured so that tilting movement of the cup occurs in such a way that translation of the mouth of the cup is minimised. The effective centre of the cup pivotal movement should lie within the confines of, or closely adjacent the cup. In the embodiment this is achieved by providing a sleeve (50) having an open lower end across which is stretched a resilient membrane (52). The membrane has a central aperture in which is secured the cup (11). Tilting movement of the cup occurring by subjecting the cup to a one-sided force A results in a complex pivotal cup motion by deformation of the membrane (52).

Abstract: The caseband (1) of the watch case comprises a central body (10) onto which a peripheral body (20) is secured in a detachable manner. In order to diminish the weight of noble metal of the case and thus its price, the peripheral body includes a hollow (21) around the circumference of the caseband. A framework (25) formed of a strong but inexpensive material is arranged within the hollow (21), when the two bodies are separated from one another, in order to assure good strength to the case.

Abstract: A ball joint and a work process for preparing such a ball joint are described, in which the housing is prepared in one piece by a sheet metal shaping process. An edge bead, which is used to close the housing by a cover, is prepared by material deformation on the outer circumference of the housing. A groove for receiving the sealing bellows, which groove is likewise located on the outer circumference of the housing, is formed during the shaping process, so that machining of the housing is not necessary.

Abstract: An anesthetic evaporator according to the bypass principle, in which a carrier gas system is partially led through an evaporation chamber, is enriched with an anesthetic vapor to saturation there, and is again fed into the bypass flow. The function of the elements that influence the metering are not impaired by the penetration of anesthetic in an unintentional position other than the position intended for operation, and that the anesthetic located in the mixed gas outlet is not influenced by anesthetic located outside the evaporation chamber. Either the evaporation chamber line leading to the evaporation chamber or the return line leading from the evaporation chamber to the flow regulating valve opens into an intermediate container, from which a channel communicates with the interior of the evaporation chamber.

Abstract: A geared multishaft turbocompressor with impellers arranged in series in terms of flow, are attached to two or more pinion shafts (6), which are arranged in parallel to one another and are driven directly via a central gear (5) or indirectly via pinion shafts at the circumference of the central gear (5). A plurality of impellers (8, 8a) are arranged in series, via the interstage diaphram of a disk-type diffuser (9) and of a return ring (10), on at least one pinion shaft end (6) in high-pressure stages following low-pressure stages (first pinion shaft or first and second pinion shafts) after the second or third pinion shaft (6). Reversing the direction of flow, i.e., admission of the gas on the high-pressure side and discharge of the gas on the low-pressure side, as well as with simultaneous reversal of the direction of rotation, a radial expander (turbine) is obtained with the same basic design.
