Title: Vehicles travelling on air cushions allowing movement   of the latter over all types of terrain
Inventor: DUCHATEAU CLAUDE M
IPC: B60V1/16
Filed: 1982-12-20
Granted: 1985-08-06
Abstract: ABSTRACT    A vehicle travelling on air cushions comprises a lifted structure and a lift arrangement which comprises at least one multilobular skirt having a plurality of first lobes open towards the inside of the vehicle.  A lower part of each first lobe converges in a downwards direction with respect to the structure.          At least in the vicinity of the rear of the vehicle, each open first lobe has within it an anti-damage lobe which diverges in a downwards direction with respect to the structure at an inclination such that the values of the angles formed between the respective outermost generatrices of the first and anti-damage 2. lobes with respect to the vertical are substantially equal.  The side edges of the anti-damage lobe are each connected along a rectilinear connection to the opposite side walls of the first lobe which converge in a downwards direction with respect to the structure.          The anti-damage lobe is also at its lower part, and in a horizontal plane, connected to the base of the first lobe.    Since the slope of the anti-damage lobe is of opposite inclination to that of the first lobe, the lower part of the anti-damage lobe trails rather than leads when at the vehicle's rear.  So the anti-damage lobe slips more easily over projections from rough terrain and lifts the skirt.    An access or gap admits pressurized air into the volume between the first and anti-damage lobes.          From this volume lower openings may lead to discharge water from the volume.

Abstract: ABSTRACT     An abrasive scrubbing pad device combined with a wringer mop in which the scrubbing pad when not in use is automatically placed in a physical position which does not interfere with the normal mop function of the mop by an auto-matic pivoting action brought into operation by actuation of the crank handle of the wringer mop.  When the crank handle of the wringer mop is moved to the position where the mop head is functional for mopping purposes, the scrubber pad is pi-voted out of the way, and when the actuating handle is oper-ated to retract the mop head between the wringer rollers during a squeeze-out operation, the scrubber pad is pivoted into its operating position.  The scrubber pad may be incor-porated into the mop when originally assembled or may be added to the mop at a later time.  The scrubber pad struc-ture is formed  so that the scrubber pad itself may be re-placed in the support structure when the pad has been rendered no longer useful by virtue of wear.

Abstract: PACKET LOAD MONITORING BY     TRUNK CONTROLLERS            Abstract A trunk controller and processor arrangement for monitoring packet traffic from a high speed trunk through a packet switching network.  Within a packet switching system, packets comprising logical addresses and voice/data information are communicated through the system by packet switching networks which are inter-connected by high speed digital trunks with each of the latter being directly terminated on both ends by trunk controllers.  During initial call setup of a particular call, central processors associated with each network in the desired route store the necessary logical to physical address information in the controllers which perform all logical to physical address translations on subsequent packets of the call.  Each network comprises stages of switching nodes which are responsive to the physical address associated with a packet by a controller to communicate that packet to a designated subsequent node. Each trunk controller has a traffic monitoring circuit for measuring the amount of traffic occurring on the attached trunk.  The monitoring circuit notifies the associated processor via the network when traffic excursions increase or decrease in excess of a multitude of predetermined percentages of load.  At initialization time and as required during system operation, the processor determines the predetermined percentages of load which are the standards utilized by the trunk controller.

Abstract: "QUICK RELEASE MOUNTING FOR SEAT BACK TRAY TABLE"                  ABSTRACT           Improved constructions for mounting seat back tray tables to the frames of vehicle seats permit the tables to be quickly removed and replaced by authorized persons without the use of tools.  Small studs on each side of the seat pivotally support apertures in the lower ends of the tray table legs.  The legs may be deflected toward each other to release their mounting engagement with the studs but means are provided to prevent such release by unauthorized persons.  In one embodiment, release can only be accomplished when the seat back is in its forward "break-over" position.  In such position, the legs can be lifted so that a frame-mounted stud having a cylindrical end inter-rupted by a pair of opposed flats will pass from a small opening in the leg through a slot narrower than the small opening to a larger opening. In a second embodiment, a torsion tube joining the leg ends has a spring-loaded pin and slot connection to one leg so that the leg can be slightly axially retracted along the tube to accomplish release. The dress cover of the seat back includes a rear portion which overlies and conceals the torsion tube.

Abstract: ABSTRACT         The identity of a key in a scanned keyboard is deter-mined by the time during the scanning cycle that a particular depressed matrix key location is scanned.  The processing circuit, commonly a microprocessor with associated memory elements, is connected to the scanned keyboard conventionally to identify the scanned key.  The memory means which are employed have a low power inactive state.  The scanned keyboard will be in a low power state as long as no keys of the keyboard are depressed.  As long as any of the keys are depressed, however, a gate controls a power safe flip-flop which activates the memory, bringing them to a high power state and the memories remain in the high power state until the processor has completed its processing cycle at which time the processor triggers the flip-flop so that the memories are again allowed to go to their inactive state, thereby achieving a sub-stantial reduction of power in the keyboard which nevertheless remains available for instant activation.
