Abstract: ABSTRACT OF THE DISCLOSURE This disclosure depicts an arc-suppression means for use in cathode ray tubes having an electron gun and ancillary electrical circuits susceptible to damaging electrical arcing currents, and wherein getter means are used to capture residual gases in the evacuated envelope of the tube.  The arc-suppression means is electrically resistive and is connected in an electrical path between the gun and a high voltage source, and its surface is physically exposed to a deposit of getter material when the getter is flashed.  The arc-suppression means includes shadowing means for shadowing at least portions of the exposed surface from a deposit of the getter material to prevent the creation of an electrically conductive shorting path capable of permit-ting an arc to  bypass or substantially nullify the arc-suppression means.

Abstract: 1                      PHN. 9113 ABSTRACT:       The connector for connecting optical fibres in accordance with the invention in principle comprises three portions which operate independently of each other: a.  centring means for centring the fibre with respect to a housing in which the fibre has been inserted, b.  a profiled edge on each housing for centring housings with respect to each other, c.  fixing means for connecting two housings to each other, the edges being resilient with respect to the remain-ing part, so that reference faces of the connector can be pressed together by the springing back of the edges. It is not necessary anymore to align optical fibres after two connector portions have been connected, because each fibre is centred in its housing and two housings will centre each other.  During placement on each other of the housing, the reference faces do not connect yet, so wear due to movement of the reference faces relative to each other will not occur.

Abstract: TITLE            INDEPENDENT STEERING AND PROPULSION SYSTEM FOR OFF ROAD VEHICLE                 ABSTRACT OF THE DISCLOSURE   A high mobility wheeled vehicle for transporting long loads, such as trimmed tree trunks or whole trees, over roadless terrain.          The vehicle has front and rear quad wheel assemblies pivotally connected to a centrally disposed elongated bed frame so as to permit lateral rotation of these assemblies about a roll axis disposed below and parallel to the longitudinal axis of the bed frame.  A linkage type roll control means interconnects the quad wheel assemblies and the bed frame to proportionately control the relative angular movement of the bed frame with respect to the quad wheel assemblies.  The roll control means includes a plurality of interconnected links plus a pair of power extensible links for selectively adjusting the steady state position of the vehicle bed relative to the quad wheel assemblies in either direction.    The quad wheel assembly incorporates a unique mounting for each of the wheels of the assembly which provides for individually controlled motors for driving each wheel, individually controlled brakes, and individually controlled, power actuated extensible links for steering each wheel.  Sensors are provided on each wheel assembly which generate signals proportional to the rota-tional velocity and direction of the wheel and proportional to the turning angle of each wheel.  A microprocessor receives all such signals and compares same with a desired turning angle and rotational velocity of the wheels in accordance with one of a plurality of modes of operation of the vehicle selected by the operator, and generates appropriate control signals to the individually controlled wheels to adjust the turning motion and the rotational velocity to that required to effect the desired movement of the vehicle.

Abstract: PAVING UNIT OF PAVING BLOCKS     ABSTRACT OF THE DISCLOSURE                  A plurality of individual paving blocks are connected together to form a paving unit ready to be applied to a base surface for forming a paving surface.  The paving blocks are molded of concrete or a similar material.  The paving blocks are connected together by an adhesive material or by pressing the blocks together before they are completely set so that the material of the blocks affords the connection.  The strength of the connection between the paving blocks is sufficient to permit the handling and setting of the paving unit while maintaining the paving blocks together.  However, the strength of the connection is less than the strength of the material forming the paving blocks so that after the blocks have been set in place and a vibrating action is applied to the paving unit, the paving blocks will separate along the connecting surfaces without damaging the paving blocks.
