The outer hub of the opposed path joint has at least two elements that are located one behind the other on the outer hub axis and jointly center the cage.

Abstract: The invention relates to a glass-metal connection, in particular for a vacuum-tube solar collector, comprising a metallic connecting part (1), which connects a heat recovery tube (3) and a enclosing tube (2) of glass in a vacuum-tight manner, one end (5) of the enclosing tube (2) being inwardly deformed in a flange-like manner in such a way that it encloses an outer edge portion (7) of the metallic connecting part (1) in a vacuum-tight manner on both sides by fusing. This edge portion (7) is expediently formed in a rotationally symmetrical manner and/or the enclosing tube (2) is produced from a soda-lime glass. The connecting part (1) is connected in a vacuum-tight manner to one or more heat recovery tubes (3).

In order to provide advantageous plug-in connections it is proposed that the plug-in noses (3) each comprise a guide tube (17) with at least one rubber-elastic clamping ring (18) which encloses the guide tube (17) on the outside, rests on an axial abutment (23) and can be subjected to axial pressure with the help of an actuator (22) penetrating the guide tube (17).

Abstract: Annular cornea implant for inserting into a cornea pocket of the human eye via a narrow, tunnel-shaped access, with the end shape of the cornea implant depending on the shortsightedness or astigmatism to be corrected. The aim of the invention is to enable the cornea implant to be implanted in the cornea pocket in a simple manner and in an optimum position. To this end, the implant has a shape memory which is impressed on the basis of the geometry and/or material of the implant, and is designed in such a way that the deformability from a starting shape enables the insertion of the cornea implant into the cornea pocket via the narrow access, and the cornea implant has an adjustment force in the end shape thereof, which enables an essentially independent unfolding of the cornea implant in the cornea pocket.

Abstract: The invention is directed to a turbine (3) for generating power in a drill string (2), including a turbine rotor (10) drivable by a fluid and a bypass device having a first bypass channel bypassing the turbine rotor (10). For varying the volumetric flow through the bypass channel, provision is made for a valve (28) and a control device driven by the fluid and having a drive element (24) by means of which the valve (28) is movable anywhere between a first and a second position. The drive element (24) produces a flow resistance in the fluid flow path downstream from the turbine rotor (10) and downstream from the valve (28) and in the flow direction takes support upon a spring (26).

Abstract: A pair of tongs with two tong limbs are connected rotatably to each other in a joint in which they are inserted and which has an axially fixed joint pin. The tong limbs are only rotatable with respect to each other. A working region and a handle region are formed in each case on one tong limb. A receiving tong limb is designed with an insertion slot which has a slot width in the region of the joint and through which the other inserted tong limb is inserted. The working regions of the tong limbs have a greater width, at least in part, than the slot width. The handle region of the inserted tong limb has a width and, if appropriate, a thickness which corresponds to the slot width. The handle covering has a reinforcing element.

Abstract: Voice recording used for authentication is transmitted to the voice portal of the service provider not by way of the voice channel, but rather by way of a data channel. In this connection, the voice recording is sent not synchronous to speech and subject to loss, but rather asynchronously and loss-free, in an extra data package (for example advantageously as a Multimedia Messaging Service (MMS) data package). For this purpose, the resources that are available as standard items in most mobile phone terminals, such as digital voice recording and MMS transmission, can be utilized. Preferably, the subscriber's identification module or SIM card in the mobile phone terminal can store and implement the corresponding control program.

Abstract: The invention relates to electroacoustic engineering, in particular to methods for converting electric signals into acoustic oscillations and to electroacoustic transducers. The method for converting electric signals into acoustic oscillations comprises exposing an oscillating system that is a gas medium pre-structured by a static electric field to an electric/electromagnetic field modulated in strength by an alternating electric signal in accordance with the shape and frequency of the modulating signal, and converting the energy of the field into acoustic energy to be released thereupon into the ambient. An electric gas-kinetic transducer developed to perform this method comprises a dielectric working element and at least two current-conducting plates that can be connected to the pole terminals of a direct voltage source and to a source of alternating electric signals.
