Title: Ct quick change assembly and force transmitting spacer
Inventor: MCKEE JERE LEE
IPC: H01H71/12
Filed: 1990-10-05
Granted: 2000-08-22
Abstract: A molded case circuit breaker is provided with a quick change current transformer assembly.      The current transformer is used to sense overcurrent conditions and apply a signal to an electronic trip unit to trip the circuit breaker. The quick change assembly includes an insulated removable plate located adjacent an open cavity in the housing in which the current transformer is located. The current transformer is donut-type disposed about a load-side conductor located in a cavity in the housing rigidly fastened to the circuit breaker frame. In order to replace a current transformer, the insulated back-plate is removed. Next the load-side conductor is unfastened and removed from the circuit breaker housing.      The current transformer is then removed from the circuit breaker housing. In order to install a new current transformer, the steps are reversed. A force transmitting spacer is disposed adjacent a bight portion of a shunt, connected between a pivotally mounted contact arm and a load-side conductor.    The force transmitting spacer transmits magnetic repulsion forces generated between the load-side conductor and the depending leg of the shunt adjacent the load-side conductor to the other depending leg of the shunt. By disposing the force transmitting spacer into the bight portion of the shunt the compression action required between the depending legs of the shunt is eliminated or reduced, thus reducing the blow open time significantly.

Title: Multi-level probe and system for measurement of physical conditions in liquid-containing tanks
Inventor: CAMPBELL ERIC
IPC: G01M3/26
Filed: 1990-10-29
Granted: 2001-09-04
Abstract: A multi-level probe for sonic range measurements utilizes a plurality of parallel reflectors that each include an opening arranged coaxially about a beam of ultrasonic energy transmitted along a reference axis from an associated transducer. The opening in each reflector permits most of the sonic energy to pass to a subsequent reflective surface, while the periphery about the opening provides echo signals for determining physical conditions in the environment through which the sonic energy has passed. A novel system is used for determining physical conditions that are a function of time differences between signals from different reflectors, calculated with a highly efficient digital signal processing algorithm.

Title: Folder with belt speed control
Inventor: BRETON RICHARD E
IPC: B65H45/22
Filed: 1990-10-31
Granted: 1994-09-20
Abstract: An improved folder includes a first series of belts which grips and moves sheet material along converging deflectors to fold the sheet material.  As the space between the deflectors narrows, a second series of belts grips the sheet material and continues its movement between the deflectors.  The first series of belts includes a first plurality of tapes disposed on a first side of a fold line and a second plurality of tapes disposed on a second side of the fold line.  The second series of belts includes a pair of creaser belts which extend from between the tapes to an outlet portion of the folder.  The speed of movement of the tapes and creaser belts is coordinated by using speed signal generators which are driven at the speed of movement of the tapes and creaser belts.  A controller compares the speed signals and maintains a desired relationship between the speed of movement of the tapes and creaser belts.  It is believed that the creaser belts will usually be driven at the same speed.  However, the creaser belts may be driven at slightly different speeds in order to compensate for deformation imparted to the sheet material before it moved between the creaser belts.

Inventor: DIELACHER FRANZ
IPC: H04M1/58
Filed: 1991-01-28
Granted: 2000-08-29
Abstract: In a method and configuration for forming a line termination at two line terminals of a telephone line, alternating signals are separated from direct signals applied to line terminals, referred to a reference variable and added to a transmission signal from a transmission terminal to form a resultant actual-value signal. The resultant actual-value signal is compared with a reference signal at a gain-controlled amplifier. The reference signal is formed with an impedance transmission function corresponding to a given termination impedance by weighting the alternating signal at one of the line terminals being connected to a current sensor resistor. A current between the line terminals is determined with a control transistor associated with the current sensor resistor. The control transistor is controlled with the gain-controlled amplifier.

In the exemplary game of Bingo, for instance, light-weight plastic balls, each marked with a letter and a number, are randomly selected and deposited into apertures in a console, by which action they are automatically identified through the breaking of one row and one column infra-red light beam of a coordinate grid of such beams.  Through electronic encoding, transmitting/receiving, and decoding, the aforesaid letter-number combination is substantially instantaneously displayed in two places on a display board.  One of these locations is on letter-labeled rows by the sequential order of the selected letter-number; the other location is on a separate row where appearance is determined entirely by the sequence in which the letter-number combination is selected. The numbers are continuously selected and progressively displayed until a round of play has been completed in accordance with various rules of the game being played. When this occurs, the display board is cleared and all of the balls are reloaded to begin the next round of play.  The console contains manually operated controls which affect the game data stored in memory and thus the display board, also.

Title: Telecommunication system
Inventor: VERHILLE HENRI ALBERT JULIA
IPC: H04L12/56
Filed: 1992-07-21
Granted: 1999-06-29
Abstract: A telecommunication system for transmitting cells through switching nodes (N1- 3 ) interconnected by groups (LG12, LG23) of transmission links, each node including an asynchronous switching network (SN1-3) which comprises several switch elements.  At least one of these switch elements possesses a routing group possibility whereby the cells are distributed over its outlets and so further over the different transmission links of the link group to which the switching network is connected.  This distribution is performed in function of a self-routing tag which is derived from external routing data associated with the cell.  At the input ports of either each or only the first switching network (SN1) of the system, the external routing data is translated in a self-routing tag which is for instance added to the header of the cell, whilst at the output ports of each or of only the last switching network (SN3) of the system respectively, the self-routing tag is removed from this header.  Some switch elements possess a multicast possibility whereby the cells are transferred to several outlets thereof and thereby to several link groups to which the switching network is connected.
