Abstract: COMMON MODE SIGNAL DETECTOR            Abstract A common mode detector for producing an output voltage (VA+VB)/2 in response to input voltages VA and VB contains a pair of MOS transistors connected in series between a pair of input terminals to which the input voltages are to be applied.  A separate feedback path runs from each input terminal through a separate load device to a gate control terminal of the respective MOS transistor and a separate other feedback path runs from each input terminal through a separate other load device to a substrate terminal of the respective MOS transistors.  In this way, the respective feedback paths deliver to the respective gate terminals respective voltages equal to (VDD+VA)/2 and (VDD+VB)/2, respectively, while the other feedback paths deliver to the substrates of the respective MOS transistors respective substrate bias voltages equal to (VSS+VA)/2 and (VSS+VB)/2, whereby the common mode voltage (VA+VB)/2 is developed at a node between the pair of  MOS transistors.

Abstract: A BRIDGE CIRCUIT FOR INTERCONNECTING NETWORKS           Abstract of the Disclosure The present invention, in a preferred embodiment, employees at least first and second logic circuits respectively connected to first and second networks.  The first and second logic circuits monitor a message being transmitted thereto to determine if it is complete and simultaneously therewith the message is temporarily stored.  If the message is complete, the one of either said first or second logic circuits, which received the message, will send an interrupt signal to a microprocessor.  In response to the interrupt signal the microprocessor will fetch the destination address portion of the message from the temporary storage and it will be forwarded to a look up control logic circuit which will act to compare the destination address with destination addresses that are stored in a look up memory means.  Each destination address information, stored in the look up memory, will include information indicating which of the first or second networks owns the station represented by said destination address.  Hence when the microprocessor receives the results of the comparison, i.e. the comparison of the destination address of the message with the destination addresses in the look up memory, it will decide whether or not to send the message through the bridge to the network not sending the message.  If no match exists because there is not a destination address stored in the look up memory to match the destination address of the message, then the message will be sent to the non sending network.          In addition the present invention provides a means for comparing the source address of a message with the destination addresses in the look up memory, whereby if the source address is not present it will be added to the look up memory so that the system "learns" the locations of stations for future use.  In addition the present invention employees means to eliminate destination addresses from the look up memory if the stations represented by those addresses are not repeatedly used within a predetermined regular use parameter.  The present system operates with a single level of address protocol (flat addressing) which provides one basis for its flexibility.

Abstract: CLAMPING TYPE CABINET LOCK                         Abstract A lock includes interengageable assemblies for mounting on a cabinet door and its door frame for  clamping  the door closed.  In preferred practice, the lock includes 1) an operating unit that has strike-engaging formations in the form of rollers which are mounted on at least one projecting arm, and 2) one or more strike units, with each strike unit having a channel and being operable to receive and releasably retain in its channel such rollers as are carried on a separate one of the projecting arm or arms.   The operating unit includes a pivotally mounted handle  for  positioning  the  projecting  arm  or  arms.   When  a plurality of projecting arms are utilized,  the operating unit includes an operating member that moves the arms in unison.  The handle is movable between a nested position and an operating position.    Preferably  a  lost-motion,   toggle  type  linkage drivingly connects the handle and the operating member.   The linkage provides mechanical advantage to aid the operator both in opening and closing the door so that such resistance forces as may be offered to door movement by various forms of gasketing and/or emission shields can be overcome with ease.   When the handle is in its operating position, the arm-carried rollers are positioned  for  entry  into  and  withdrawal  from  the  strike channels.   Once the rollers have entered the strike channels, pivotal movement of the handle toward its nested position will cause the rollers to move in unison along the strike channels, thereby causing a wedging action that "draws" or clamps the door snugly toward the door frame.   The strike unit has a  spring biased track member that engages the rollers to bounce the door toward an open position if an attempt is made to close the door while the handle is  in its nested position,  i.e., while the rollers are out of proper orientation for insertion into the strike channels.

Abstract: ABSTRACT        "MINERAL CUTTER PICKS AND PICK ASSEMBLIES"         A mineral cutter pick (2) is mounted in holding means (6, 8) with passages (10, 12) in the pick and the holding means for supplying fluid to an opening near the pick cutting edge.  Respective sealing sleeves (16, 18) are provided in the adjacent ends of the passages in the pick and holding means and receive the opposite ends of a tubular connector (14).  At least one of the sealing sleeves has its outer face exposed to the fluid supply pressure so that sealing with the associated end of the connector is assisted by the pressure force. The ends of the connector are formed as spherical enlargements (26, 28) to allow free pivoting in their sleeves and at least one end is axially displaceable in its sleeve while maintaining sealing contact.  In this way axial and angular misalignments and movements between the pick and the holding means can be acommodated without disturbing the fluid supply.            (Fig. 2)

Abstract: ABSTRACT     A buried grid structure is produced in a semiconductor material particularly a silicon wafer, while using a metallic grid mask.  The buried grid is formed directly within the semiconductor material by contradoping ion implantation by means of a high energy accelerator through the metallic grid mask.  The bars or ribs of the metallic grid mask stop the ions passing there through so that two vertically separated and laterally offset buried grid structures are produced.  By beveling the periphery of the wafer, buried conductive structures are formed at the same time as connections between the buried grid structures and a control electrode provided on the back side of the wafer.

Abstract: ABSTRACT:         The fading circuit comprises first and second video signal inputs (1,12) for receiving 8 bit parallel digitally encoded video signals and first and second fading control signal inputs (5,16) for receiving 8 bit parallel fading control signals.  First and second multipliers (4,15) multiply the video signals by the fading control signals.  The outputs of the multipliers (4,15) are truncated to 9 bits and fed to first and second inputs of an adding arrangement (11).  A dither signal is fed from a dither signal generator (22) to the carry input (24) of the adding arrangement (11).  The output of the adding arrangement (11) is fed to a ROM (28) which is programmed to add 1/256th of the output of the adding arrangement (11) to the output of the adding arrangement (11) and produce an 8 bit output which is applied to the output (31) of the fading circuit.  By adding the dither signal amplitude transitions in the out-put signal at particular settings of the fading control signals are blurred and do not produce such a disturbing effect on the display screen.
