The devices of the simulation include several individual driving simulators of the same kind, disclosed in U.S. Pat. No. 4,077,138 Foerst issued Mar. 7, 1978 being connected to each other via signal lines; each one including computing devices, computing the speed, the parallel track position, the track angle, the sloping position in case of the vehicle being a bike, and the centrifugal acceleration; an interface device transferring the computed data into video signals; a road picture generator; ...

A driving mechanism for driving a moving handrail of an escalator and the like. The driving mechanism include driving rollers and guiding rollers which are disposed to confront with each other through the moving handrail interposed therebetween. The driving rollers are secured to a movable plate, while the guiding rollers are attached to fixed plates. The movable plate is adapted to be moved in the direction perpendicular to the moving handrail, while the fixed plates are firmly secured to a par...

This invention relates to a driving control for a tracked vehicle of the kind steered by its tracks comprising a control lever which is displaceable in a forward and rearward direction to operate both driving motors together in the forward or reverse direction, the lever being mounted so that it can be turned about its axis to differentially affect the driving motors and steer the vehicle.

A cutter member for use in cutting a hole in plastic pipe having a thick wall or a thin wall. The cutter member is rotated and advanced with a positive predetermined lead against the pipe, the cutter member being so designed that after it has cut the initial chips off the outside curvature of the pipe, it cuts a continuous chip by a peeling action and the initial chips and continuous chip are discharged inwardly of the cutter member above the coupon being cut. The cutter member may be repeatedly...

An apparatus for driving a tunnel, the apparatus having a knife shield composed of a circular array of elongate knife implements supported by a frame and attachable to a drive frame which can be moved to cause the implements to penetrate into a working face in order to excavate material therefrom. To the rear of the knife shield there is an advanceable temporary lining composed of tube sections arranged end-to-end and designed to support the newly-formed tunnel. This advanceable lining extends i...

The driving tool for installing fasteners in workpieces includes a motor operated driver, a clutch mechanism engageable with the driver, and an adapter including a wrenching mechanism and which connects to the driving tool and cooperates with the clutch mechanism to effectuate rotation of the wrenching mechanism. The adapter includes means to engage the clutch before the fastener engages the workpiece. The preferred means is a detent assembly which is secured to the main body of the adapter and ...

Driving hollow piles by utilising a hollow drive tube inserted in the tube and applying hammer blows to an abutment at the bottom of this tube.

Disclosed is an apparatus for increasing the effectiveness of hammer-type pile drivers by making possible the use of higher hammer velocities without damaging the pile or the equipment. The apparatus includes a pair of aligned cylinders of unequal diameter, the smaller of which contains an anvil piston and the larger of which contains a driving piston, connected to a pile cap engageable with a pile. Means are provided for applying a deadweight load to the apparatus and for maintaining the space ...

A device for simulating a ride of a road. The device comprises several range wedge generators, each of which generate two rows of spots on the screen of the monitor, meeting at the horizon and being symmetrical to the middle of the road; ceiling area pair generators, plate area pair generators, wall area pair generators for the representation of equidistant rectangular or nearly rectangular areas in the road picture; control devices for these area pair generators; random access memories which st...

The devices for the simulation include Several video signal generators each of which brightening on a monitor one light spot pair representing two road border posts, An analog deflection voltage generator for the horizontal and vertical shifting and for the width and height alteration of said light spots, using an evaluation matrice, integrators, and digitally actuated electronic switches, An analog computing device for the computation of the speed signal, simulating a decreasing rotation-torque...
