Abstract: A system for monitoring the course and braking means of a vehicle are provided, which is freely movable and particularly inductively steered. The vehicles comprise drive means and at least one steerable driven wheel, braking means, and a sensor for scanning a guideline. The system comprises an arrangement (25, 27), in which an emergency braking operation for stopping the vehicle within an emergency stopping distance is generated in dependence on a signal which corresponds to the angle between the longitudinal axis of the vehicle and the guideline, and another signal, which corresponds to the lateral departure of the longitudinal center line of the vehicle adjacent to the sensor from the guideline. The emergency stopping distance is shorter than the distance which the vehicle would travel to collide with an obstacle. Limiting values for a maximum or changing steering angle, the contour of the vehicle, the speed of travel and the braking distance under maximum load.

Abstract: A detachable hinge assembly consisting of a generally L-shaped member secured to a movable structure and a second generally z-shaped member secured to a frame, the L-shaped member having openings in each of its leg portions through which leg portions the Z-shaped members extend. The relationship between the openings and leg portions is designed so that the upward and sideward member of the L-shaped member relative to the z-shaped member is restricted, while permitting the L-shaped member to be pivoted relative to the z-shaped member, so that the movable structure to which the L-shaped member is attached can be disengaged from the z-shaped member without the use of tools.

Abstract: A single large balloon tire bicycle wheel having a vertical frame attached to the axle extending upward to support handles is provided with a set of horizontal plastic tubes for holding a set of golf clubs. The plastic tubes are mounted in sheet metal brackets on either side of the wheel and have club head holding blocks disposed on the forward ends of the tubes. The tubes are staggered such that each club head is held in place by the holding block on the next lower tube. A tubular strut is attached to the lower end of each tube holder bracket and has a pair of short legs attached thereto. The caddy, when not being moved, rests on one pair of legs leaning slightly to one side. A broad handle may be folded forward when the caddy is at rest, contacting the tire, and usable as a seat.

Abstract: Recreation and work-type trailers are difficult to maneuver once detached from the towing vehicle even with the conventional dolley wheel in place. This device includes a horizontal main bar with a pair of plates one at each end being mounted to the underside of the main bar by a bolt and spring loaded to give a limited flexibility thereto. A central socket is pivoted to the upper side of the main bar and receives the stem of the trailer hitch. A handle socket is secured adjacent each end of the main bar also on the upper surface thereof and incline upwardly and outwardly therefrom and selectively receive an elongated handle so that the respective end of the main bar can be elevated by the handle and "walked" forwardly or backwardly or sideways as desired thus maneuvering the trailer readily and easily.

Abstract: A stacking cart for paper products, sheet material, or the like, is provided comprising a generally horizontally extending movable stand having four vertically oriented substantially identical, V-shaped troughs disposed thereon. The V-shaped troughs are each formed from a unitary sheet metal part with at least one wedge-shaped vertical flange. A plurality of generally horizontally extending shelves are disposed in the V-shaped troughs and fasteners extending through the vertically oriented flanges on the V-shaped troughs secure the troughs in a back-to-back relationship. Each of the troughs are inclined with respect to a centrally located vertical axis, with the tops of the troughs being disposed inwardly with respect to the bottom of the troughs so that sheets of material disposed on the horizontally extending shelves are gravity biased inwardly toward the centrally located vertical axis.

Abstract: A carrier for a pair of skis comprises on each ski, in the region of the center of gravity of the ski assembly (i.e. the combination of ski and binding) a stirrup-shaped or bail-shaped handle which is movable between a retracted position in which the handle overlies the upper surface of the ski in the region of the center of gravity of the assembly and below the ski boot, and a position in which the handle extends outwardly beyond a longitudinal edge of the ski. A pair of skis can be carried in a balanced manner by gripping both handles thereof although the device also enables balanced carrying of a single ski.

Abstract: An implement frame (12) is supported by two pairs of laterally spaced wheels (36, 37 and 38, 39) whose vertical position relative to the frame is controlled by a pair of parallel master cylinders (61, 62) connected to one pair of wheels (36, 37) and a pair of parallel connected slave cylinders (63, 64) connected to the second pair of wheels (38, 39). The master and slave cylinders are series connected to provide even raising and lowering of the implement frame. The parallel connections between corresponding ends of the master and slave cylinders (61, 62, 63, 64) provide a walking beam effect with resulting equal loading on the wheels (36, 37, 38, 39).

Abstract: An air induction structure is designed for an air cleaner on an automobile furnished with an engine compartment in its front body and a grille at its front end through which the engine compartment is open to the outside. The air induction structure includes an obstructing member, which is located in a position in which the obstructing member is across the substantially straight path connecting the opening of an air intake duct, connected to the air cleaner, and the part of the grille in the same vertical longitudinal planes, with respect to the automobile, as the opening of the air intake duct, so that the obstructing member prevents air, drawn into the engine compartment through the part of the grille, from travelling straight into the opening of the air intake duct.

Abstract: A device which is for handling refuse or the like material; which has a container having a bottom surface provided with a pair of intersecting and downwardly open grooves, a pair of wheel recesses disposed at the opposite ends of one groove, and a mounting recess and a latch recess disposed at the opposite ends of the other groove; and which has a dolly having an arm extended through the one groove, elements in the mounting recess mounting the arm on the container for movement of the arm between an upper position and a lower position, an axle mounted on the arm and extended between the wheel recesses, a wheel mounted on the axle at each wheel recess, and a latch mounted on the arm at the latching recess and adapted to latch the arm in the lower position, the wheels being within the wheel recesses when the arm is in the upper position and being extended therefrom for rolling support of the device when the arm is in the lower position and the mounting elements serving resiliently to urge the arm toward the uppe

Abstract: An ice skate that provides exceptional lateral stability includes a boot having a sole plate extending longitudinally between the toe portion and the heel portion of the boot. A pair of adjustable shock absorbing mounting assemblies is joined to the toe portion and the heel portion of the sole plate. A pair of ice engaging members is provided, each secured to one of the shock absorber mounting assemblies. The ice engaging members extend transversely with respect to the longitudinal axis of the boot to provide high lateral stability. Projecting downwardly from the lower surfaces of the ice engaging members is a plurality of laterally spaced, longitudinally extending ribs which are adapted to slide on ice.
