Title: Actuating drive comprising two friction partners
Inventor: MICHEL PETER
IPC: E05F15/16
Filed: 1992-05-19
Granted: 2001-05-08
Abstract: The invention is used in an actuating drive comprising two friction partners, in particular a geared actuating drive with a toothed worm wheel which braces itself radially with a cup-shaped edge part against an outer rim part of a concentric slave disc which is driven over an at least tangentially elastic damping liner. The invention is designed to prevent squeaking noises between the friction partners when there is reciprocal relative movement, and to require minimal expenditure of time and energy for construction and assembly. The invention provides in each case for the one rim part to have an even edge surface and for the other rim part to have an uneven friction surface, with elevations only abutting on the one friction surface and with depressions situated inbetween. An application is particularly suited for motor-vehicle window-lifting drives and can be used between the worm wheel and over a tangentially elastic damping liner, giving a reciprocal, radial bracing of the slave disc which is in a slaving relationship.

Title: Apparatus for detecting relative movement
Inventor: MITCHELL DONALD K
IPC: G01D5/38
Filed: 1993-05-04
Granted: 2002-08-13
Abstract: The apparatus disclosed herein employs a grating or scale (13) which concentrates light at a preselected wavelength into the positive (33) and negative (35) first orders while minimizing the zeroth order (31). The scale (13) is illuminated with monoch-romatic light of the selected wavelength and a poly-phase periodic detector (25) has its sensing plane spaced from the scale a dis-tance less than W: 2 tan .THETA. where .THETA. = arcain [.lambda.: P], where W  is the width of the illuminated region of the scale. The period of the poly-phase detector is equal to P/2 so that each detector element (51) or phase responds principally to interference between the positive and negative first orders without requiring magnification or redirection of the diffracted light. Preferably, the distance of the sensing plane from the scale (13) is greater than W: 2 tan .PSI. where .PSI. = arcsin [3.lambda.: P], so that the detector response does not include substantial components from diffraction orders higher than the first.

Abstract: An encapsulated cable for a suspension bridge or a cable-stayed bridge, the cable (10) being encapsulated by a wrap (16) which is formed by spirally winding a flexible strand (5) of a synthetic rubber tightly therearound. The strand is wound with each wind thereof overlapping one-half the width of the preceding wind, thereby forming a uniform thickness, double layer wrap.      After the spiral winding step the wrap is heated to heat seal the superimposed layers to one another to thereby seal the seam formed therebetween and shrink the wrap into tight engagement with the cable. The strand, specifically the outermost layer of a laminated multiple layer strand, is precolored with a suitable colorant to eliminate the need for after painting the wrap to obtain a suitable color match between it and adjacent portions of the bridge structure. A joint between the cable and an annular opening in a support member (14) through which it passes is sealed before the spiral wrapping step by positioning an elastomeric annular member (20) around the cable in engagement with the cable and the support member, tightly circumscribing the annular member with a synthetic rubber sleeve (26) to ensure that its engagement with the support member and the cable is sealing engagement, and then by performing the cable spiral wrapping step beginning at the support member to cover the synthetic rubber sleeve as well as the portion of the cable extending therebeyond.

Abstract: A system for electronic imaging of a hemispheric field of view includes a camera for receiving optical images of the field of view and for producing output data corresponding to the optical images.   The camera includes an optical assembly for producing images throughout a hemispheric field of view for optical conveyance to an imaging device or photographic film. The optical system assembly has lens components that selectively emphasize the peripheral content of the hemispheric field of view.   An electronic imaging device within the camera or a film-to-digital data conversion system provides digitized output signals to input image memory or electronic storage devices.  A transform processor selectively accesses and processes the digitized output signals from the input image memory according to user-defined criteria and stores the signals in output image memory.  The signals in the output image memory can then be displayed according to the user-defined criteria.

Title: Bit rate reservation of switching nodes of a synchronous network
Inventor: SERVEL MICHEL
IPC: H04L12/56
Filed: 1995-07-20
Granted: 2000-02-01
Abstract: Bit rate reservation is effected by means of a reservation cell containing a requested bit rate transmitted from a calling terminal  to  a  called  terminal  via  switching  nodes  of  an asynchronous  network.    At  each  node,  a  bit  rate  increase request is at least partially satisfied even if the difference between the requested bit rate and the current bit rate is greater than the bit rate available at the node.   The node replaces the requested bit rate in the reservation cell by a new bit rate lower than the latter so that the called terminal receives the lower new adopted bit rate by the nodes.   An acknowledgement cell retransmitted with this lower new bit rate by the called terminal renders uniform the adopted bit rate at all the nodes.   If no acknowledgement cell has been received after a predetermined time-delay the nodes revert to their initial state, with the current bit rate preceding the bit rate reservation.
