Patent NO-158562-C (NO)
Inventor: JUNGKIND ROLAND
IPC: A63C9/20
Filed: 1985-10-21
Abstract: A cross-country ski binding for use with a ski boot having a front extension portion on its sole, with the front end portion providing a hooking area on its top surface, has a double-armed retaining lever whose arm which faces towards the rear of the binding forms a hook for engaging behind the hooking area on the extension portion of the boot. The second arm of the retaining lever can be secured in the closed position of the binding by a locking lever pivotally mounted at the front end of the binding. The locking lever is spring-loaded towards the position of locking the retaining lever in the closed condition of the binding. The binding also has a release button which is disposed pivotally coaxially with respect to the retaining lever and which is limitedly pivotable relative to the retaining lever, against the force of a retaining spring, thereby to displace the locking lever into a position for releasing the retaining lever. The retaining lever also has an abutment which is engaged by the first extension portion of the boot upon insertion thereof into the binding to pivot the retaining lever into the binding-closing position.

Abstract: The invention relates to a method and apparatus for detecting specific target cells in a simple and time-saving way, using paramagnetic particles, antibodies recognizing the Fc portions of target-cell associating antibodies and target-cell associating antibodies directed to specific antigen determinants in the target-cell membranes. Incubation of the cell suspension with detergent and/or second antibodies or antibody fragments, prelabeled or not with fluorescent agents, metallocolloids, radioisotopes, biotin complexes or certain enzymes allowing visualization, dramatically increase the specificity of the method. The method and apparatus described provides a solid support and permanent record which is easily viewed by microscopy, permits viewing and quantification of the whole specimen rather than small fractions thereof and allows the use of large specimen volumes to be analysed, the device may also be scanned automatically by conventional densitometric technology. The method and apparatus can be used for isolation of the target cells by magnetic field application, and a kit and apparatus for performing the method according to the invention is described.

Abstract: An echo canceller is described comprising an adaptive filter (15). The adaptation rate of the adaptive filter (15) is controlled by means of a control unit (29) determining the appropriate control signal in response to its input signals (x(k), u(k), e(k)). If the described echo canceller is inserted, for example, in the subscriber set of a telephone network, the adaptation process is to be effected only when the far-end subscriber is talking and the near-end subscriber is silent. If such a decision is automatically made with the associated signals (x(k), u(k)), an erroneous decision may at least temporarily considerably degrade the quality of the telephone communication.      For this reason, the adaptation rate of the adaptive filter (15) is provided to be controlled in a gradual manner by means of the control unit (29) in response to suitably chosen mean values of its three input signals (x(k), u(k), e(k)), when the far-end subscriber is talking.

Abstract: SPLIT SCROLL FOR CENTRIFUGAL BLOWER                  ABSTRACT OF DISCLOSURE          A split scroll diffuses and directs air upwards from the circumference of a forwardly-curved centrifugal fan to a discharge plane to one side of the fan.  The scroll has a first monotonically increasing curved wall that extends from a cutoff point near the circumference of the rotor, in the direction of rotation, to the discharge plane.  A second monotonically increasing curved wall extends in the opposite direction from the cutoff point up to the discharge plane.  The first and second curved walls are mirror images of one another taken at the plane corresponding to the air flow tangent that passes through the cutoff point.  A curved cover above the fan at the exit plane blocks line of sight noise from radiating directly from the fan rotor into the work space or living space.

Abstract: An optical waveguide plug connection for the transmission of high continuous wave light powers from an incoming optical waveguide (5) into an outgoing optical waveguide (15) comprises a metallic plug housing (1) equipped with a metallic centering element (2). The incoming optical waveguide (5) and the outgoing optical waveguide (15) project into the centering element (2), the end faces (13, 23) of the two optical waveguides (5, 15) being arranged opposite each other. The width of the gap (24) is approximately in the range of from 5 to 30 micrometres. The core diameter of the outgoing optical waveguide (15) is approximately one third larger than the core diameter of the incoming optical waveguide (5). The gap (24) is filled with gas. The plug housing (1) is connected to a housing (25) of large surface area which dissipates heat. Using this plug connection, continuous wave powers of up to some 100's of watts in the case of visible to infrared laser light can be transmitted with a high degree of coupling without danger to the end faces (13, 23) of the coupling connection.

Abstract: In a communications system, a base station has a memory for storing interval control values representative of time-varying traffic pattern of the communications system. A time-keeping circuit recalls a stored interval control value from the memory according to different time of day and a battery-saving command signal is sent from the base station at variable intervals as a function of the value recalled from the memory. Power supplies of a remote station are interrupted for a constant brief interval in response to the battery-saving signal, so that the remote station is powered for a shorter interval during a light traffic period and for a longer interval during a heavy traffic period. In a preferred embodiment, traffic data is automatically collected from the communications system and the stored interval control values are updated according to the collected traffic data.

Title: Impedance synthesis multiple loop using filtering means
Inventor: WILLOCX EDDIE L M
IPC: H04Q3/42
Filed: 1991-05-10
Granted: 1995-05-30
Abstract: To supervise a telephone subscriber line (v'2, v'1) and provide it with adjustable AC and DC termination impedances from the exchange (v1, v2), these are supplied by an impedance synthesis multiple loop split into separate DC and AC loop parts by filters at the output of a sense amplifier in the common loop part and fed (e) through a Herter bridge.  The amplifier AC output has however to be limited to avoid saturation by a larger DC signal. It now includes a Miller effect integrator output stage (A2) with a low pass frequency response supplying the DC loop and also feeding back an input stage (A1) so that the latter exhibits a high pass frequency response with a DC free output to drive the AC loop and the consequent ability to supply a larger AC output.  Further circuits improve dial pulse detection (LP), reduce external capacitances (C1) and limit power consumption (PG5 and PG6).
