Abstract: A turbomachine including a case, a rotor, a plurality of rotor blades on the rotor each having a blade tip, a shroud around the rotor blade tips, and means mounting the rotor on the case for rotation about a centerline of the case and for bodily shiftable movement in the direction of the centerline.  The rotor blade tips and an inside wall of the shroud flare radially outward in the direction of the centerline so that when the rotor moves in the direction of the centerline toward the shroud a clearance gap between the blade tips and the inner wall of the shroud decreases and vice versa.  An electromagnetic actuator on the case magnetically attracts a thrust plate on the rotor against a net dynamic force on the rotor.  A control system of the actuator controls the magnetic attraction of the actuator in response to signals from a position sensor measuring the actual magnitude of the clearance gap to maintain the actual clearance gap at a predetermined magnitude.

Title: Linerless thermal and thermal transfer labels
Inventor: STENZEL HERBERT J
IPC: C09J7/22
Filed: 1993-07-14
Granted: 2006-02-07
Abstract: Thermosensitive linerless labels (either thermal labels or thermal transfer labels) which can be used with food products contain a pressure sensitive adhesive covering one face of a substrate having a thermosensitive layer on the opposite face, and a release coat covering the thermosensitive layer. The release coating is preferably applied directly to the thermosensitive layer, and preferably is prepared by application and then drying of a formulation containing between about 5-25 parts chromium pentahydroxy (tetradecanoato) di-, and about 75-95% water or alcohol. Alternatively, the release coating may be a UV curable silicone with about 1-3% by weight photoinitiator. After the coatings are applied, the stock is dried in a manner that will not adversely affect the thermosensitive layer, e.g. by ultraviolet rays, or air drying at a temperature of less than 150°F. A web comprising the substrate may be slit into individual rolls, and perfing or die cutting is practiced to form individual labels.

Abstract: Distortion and instability due to echoes in conference communications is reduced through the use of an echo canceller disposed in a conference bridging circuit. This circuit includes a signal combiner which receives information signals from each of the parties in the conference communications and provides an outputsignal which is a combination of the received information signals and an echo compensation signal. The echo canceller provides this echo compensation signal in response to the combiner output signal. Advantageously, the echo canceller can be fixed or adaptive. In the latter case, the adaptation can be in response to the received information signals or to training sequences.

Abstract: A volume flow meter for displaying two-dimensional volume flow through a vessel, comprising an ultrasound instrument with scan head, a location and orientation sensor mounted to the scan head, and a computer connected to the ultrasound instrument and the sensor. The scan head is adapted to be positioned adjacent the vessel under investigation, for generating a raster of pixels which defines a colour image representing flow velocities in the vessel through an image plane of the scan head.      The sensor measures position and orientation of the scan head in three dimensions and generates a signal representative thereof to the computer. The computer receives said raster of pixels and the signal from the sensor and in response calculates the position and orientation of the vessel axis in three-dimensions responsive to orientation of the image plane longitudinally of the vessel. The computer then determines an angle a between this axis and the image plane responsive to orientation of the image plane transversally to the vessel. Finally, the computer calculates and displays the volume flow as a summation of the flow velocities scaled by the tangent of the angle e.

When only the chain is used, the door can be safely opened partially to preview the prospective visitor. The exterior component consists of a flanged plates wherein a flanged portion is designed to fit into a corresponding slot in the door jamb to inhibit forceful entry into the dwelling. The hinge screw components includes a screw having a threaded portion and a protrusion member.  The screw of a traditional hinge is replaced with the hinge screw to prevent a closed door from being removed from their hinges when the hinge pins are removed.  The door striker component reinforces the drive-in style of dead bolts by supporting the outer edge of the bolt collar.

Abstract: L'invention concerne un dispositif optique (3) non linéaire à semiconducteurs qui se compose d'un guide d'ondes actif avec une construction à puits quantique dans la région active. Ledit dispositif (3) est alimenté en courant d'attaque à un niveau entraînant la transparence du matériau par rapport à une pompe optique. Une non linéarité optique apparaît lorsqu'un rayonnement d'entrée présente une longueur d'onde inférieure à celle équivalant à la bande interdite de la région active (lambda<lambdag), l'effet étant atteint à des puissances d'entrée optiques relativement faibles. La non linéarité est suffisamment rapide pour qu'un dispositif de commutation muni du dispositif selon l'invention faisant office de démultiplexeur puisse être utilisé à des débits binaires de l'ordre de Tbits/s. Dans un mode de réalisation utilisant un multiplexeur, la non linéarité peut être exploitée dans un coupleur directionnel (40), une pompe optique étant utilisée de manière intermittente afin de réguler la transition d'un signal de données, multiplexé par répartition dans le temps de manière à détecter un canal sélectionné. D'autres applications prévoyant un dispositif optique logique sont décrites.

Abstract: A broadcast network, which may have multiple affiliated television stations each broadcasting in different geographic areas, is provided with one or more easy-to-use telephone numbers. The broadcast network, in turn, assigns one or more the these numbers to its affiliated television stations, each of which allows advertisers to prominently display one of its broadcast network's telephone numbers in direct-response television advertisements broadcast by the affiliatedstations in their respective geographic areas. Different advertisements broadcast on different television stations affiliated with that broadcast network may then display that same number, regardless of the geographic area in which the broadcast is received, and the time at which the advertisement is displayed.When a particular advertisement sponsored by a particular advertiser is displayed on a TV program, viewer/listeners can dial the broadcast network's telephone number in response to the advertising, in order to initiate a transaction. The call is routed based upon its "context", to a specific terminating telephone number for a transaction processor serving the advertiser associated with the advertisement. "Context" based processing is accomplished by using a call-routing database to uniquely associate each incoming call placed to the broadcast network telephone number with an advertiser's specific terminating telephone number, illustratively based upon the time period that the call is made, and the viewer/listener location where the call was originated, both of which together determine the particular advertisement to which the caller was responding. Ambiguities arising from (a) overlap of the geographic areas in which affiliated stations broadcast or (b) short time intervals between broadcast of different ads, are resolved by querying a caller using a voice response system.

Abstract: A system for encoding video frames in accordance with the MPEG standard, in real-time. Motion vectors are calculated during the forward prediction of B frames and P frames using a telescoping procedure. Similarly, a telecoping procedure is used for calculating motion vectors for B frames during backwards predictive coding. The use of telescoping for the backward predictive coding results in B frames being coded in the wrong order. The correct order for B frames is re-established by writing the frames to a buffer (97) in the order in which they are generated and then reading the frame data from the buffer in tbe order in which they are required for transmission or recording purposes. The use of the telescoping procedure reduces significantly the amounts of computation required for calculating motion vectors during predictive coding for frames which are displaced by more than one frame period. The use of a buffer to reorganise the frames does not add significantly to the overall hardware requirement because such a buffer would often be used for smoothing out irregular data rates.
