Patent EP-0584649-A1 (EP)
Inventor: WALKER MICHAEL
IPC: H04R3/02

Abstract: In a circuit arrangement with means for echo cancellation by controlling the sidetone suppression for electroacoustic installations, particularly for a communication terminal (1) exhibiting a hands-free talking device (9), with transmitting and receiving branch (2 and 5) and gain-controllable amplifiers (VS, 4 and VE, 6), the sidetone suppression is set in such a manner that echo signals occurring during the speech phase are lowered to levels which do not interfere (simultaneous masking). According to the invention, means (10) are additionally provided or can be connected by means of which it is possible individually or automatically to cancel or to lower to non-interfering levels even echo signals which occur after the speech phase and the subsequent decrease in the hearing threshold of the human ear in time. As a result, a correct hands-free talking is also possible with the usual terminals (1) with little expenditure and therefore inexpensively when the connection is over long transmission paths, for example via satellites or via transmission links having a long propagation time. <IMAGE>

Abstract: The invention relates to a T-shaped deflection device (11) for a linkage, in particular for the actuation of at least one skylight (18,23,25a), having three coupling elements (2,3,4) which are connected to one another in terms of movement, are arranged at an angle with respect to one another in each case and can be displaced preferably in a common plane. Said T-shaped deflection device is connected, on its drive side (4), to a drive (12), whereas its driven coupling elements (2,3) are connected indirectly, for the most part via extension elements, to the sash which is to be actuated. Both in the case of the production of this T-shaped deflection device and in the case of the connection to the drive, on the one hand, and further-guidance elements, on the other hand, it is very advantageous for all three coupling elements (2,3,4), according to the invention, to be of identical design. In order to be able to use the deflection device both as a right-hand configuration and as a left-hand configuration, the device housing is equipped with a convertible guide part (5) for the at least one flexible deflection element (7). Moreover, two of the coupling elements (2,4) are drive-connected directly, but releasably, by means of one of the two connecting elements (6). At least the other connecting element (7) is a flexible deflection element. <IMAGE>

Abstract: A device for optically scanning a record carrier (1) with a recording layer of phase-change material is described. The radiation beam supplied by a radiation source (4) is focused on the recording layer by an objective system (5). Crystalline information areas may be written by means of the beam in the initially amorphous recording layer. The information areas are erased by means of pulses of the radiation beam, while according to the invention the erasing pulses have such a short duration that the areas of the recording layer heated during erasing to a temperature lower than the melting point of the recording layer remain above the crystallization temperature of the recording layer for a period of time which is shorter than the crystallization time.

Abstract: In the magnetic chuck disclosed herein, a pair of elongate pole members are arranged to provide magnetic contact with a workpiece along parallel lines and thus are somewhat in the nature of rails. Preferably, the ends of the poles are segmented and provide for height adjustment to accommodate workpieces which are not entirely flat. The pole members extend along the sides of an elongate base plate with a space therebetween. Interposed between each pole member and the base member is a relatively thin layer of permanent magnetic material which resists demagnetation. A switchable permeable magnet is provided between the pole members above the base plate and this latter permanent magnet is surrounded by a coil which allows the polarity of its magnetism to be switched so that it either aids or opposes the thin magnetic layer in polarizing the pole ends.

Abstract: A gas chromatography system featuring column bifurcation and pressure tuning. The system of this invention incorporates a bifurcated system in which samples eluting from a first separation column are directed selectively through one of two or more additional separation columns. Flow directing is achieved through the use of valves which switch carrier gas which are outside of the path of the analyte mixture. Effective tuning of the system is provided by adjusting the intermediate pressure which controls the effective lengths of the initial separation column and the additional final separation columns.
