Abstract: A tractor vehicle (10) is provided with segregated engine (45) and heat exchanger compartments (64). The heat exchanger compartment (64) is supplied with ambient air from an intake grille (24) above the heat exchanger compartment. The process air from the heat exchanger compartment is exhausted forwardly through a front grille (40) location on the tractor. The engine compartment is ventilated by a forced air system induced by the heat exchanger compartment exhaust fan (80). Engine compartment process air is drawn to the downstream side of the primary heat exchanger (76) and is discharged along with the heat exchanger compartment process air, through the front grille of the tractor.

Abstract: The specification discloses a nestable transport table 10 having a table top 14. Front legs 20 and 22 extend downwardly from the under side of the table top 14 and are spaced inwardly from the lateral edges thereof. Rear legs 34 and 36 extend outwardly and then downwardly from the rear end of the table top 14 so that the rear legs 34 and 36 are spaced outwardly from the lateral edges of the table top 14. Telescoping members 38 and 40 extend downwardly from the lower ends of the rear legs 34 and 36 and are movable between a retracted position and an extended position. In the extended position, the telescoping members 38 and 40 may be locked to place the transport table 10 in a tilted nesting position. Wheels 26, 28, 42, and 44 are mounted at the lower ends of legs 20 and 22 and the lower ends of the telescoping members 38 and 40.
Abstract: A walking machine comprises two pillars 8 and 11 normally resting on the ground and supporting a load 22 on a platform 21 eccentrically between the pillars. A lifting leg 5 is connected by means of ball joints to a foot and the platform and can be moved by means of two double acting hydraulic jacks to alter its inclination in two planes. In use the platform is first tilted by extending the lifting leg towards the load and at an angle. One of the jacks is then actuated to get the lifting leg vertical so that the platform drags at one end. The platform is then levelled and the process repeated for as many times as are necessary.
Abstract: There is disclosed an apparatus for automatically maintaining the speed of a vehicle at a desired speed as selected by the vehicle operator. The apparatus includes one feedback loop for monitoring the actual vehicle speed and another feedback loop for monitoring the engine load. The engine load feedback loop enables the speed control to anticipate the effects of changes in road speed so as to minimize or eliminate undershoot or overshoot of the control system. A signal representing the actual vehicle speed is combined with a signal representing the engine load to generate a composite feedback signal to a comparator circuit. The comparator circuit compares the feedback signal with a signal representing the desired vehicle speed and generates control signals for maintaining the speed of the vehicle at the desired speed.
Abstract: A framework for removable attachment to a skate board is made up of longitudinal and transverse bars or rods fastened together in the form of a grid which is in the shape of a shallow channel.
Abstract: A wheeled frame is provided including a lower horizontal main portion having a pair of opposite side rear wheels journalled therefrom and a pair of opposite side front caster wheels. The frame includes an upstanding handle assembly supported from the rear of the lower horizontal main frame portion and the upper end of the handle assembly includes a horizontal transverse handle portion. A horizontal transverse brake bar generally parallels and is supported from the handle portion beneath the latter and is guidingly shiftable toward and away from the handle portion. A brake member is shiftably supported from the frame for movement between applied and released positions and the brake member includes wheel braking portions engageable with the rear wheels to frictionally brake the latter when the brake member is in the applied position.
Abstract: A device for the control of the traveling speed of a motor vehicle with a regulating member actuatable by the vehicle driver, the gas pedal emitting an electrical signal, the gas pedal being connected with the desired value input of an electrical controller, the output signal of which acts on a positioning actuator, the latter being coupled with the element, particularly the throttle valve, which influences the fuel-air mixture, the instantaneous setting position of the positioning actuator being transmitted as an electric signal to the actual value input of the controller. The actual value input or the desired value input of the controller is driven by a circuit which produces a signal for influencing the position of the throttle valve, which signal is dependent on at least one factor to be monitored.

Abstract: A support for securing a battery pack in a vehicle wherein the battery pack includes a plurality of batteries bound together between two end plates having threaded mounting studs affixed thereto and projecting outwardly therefrom. The support includes a horizontal tray having an upstanding peripheral rim, a retainer flange projecting outwardly from the rim along one side of the tray, an upstanding mounting plate on the side of the tray opposite the retainer flange, and a retainer bar positioned above the retainer flange and appropriately secured thereto. The upstanding plate and retainer bar have apertures for receiving the studs on the battery pack.

Abstract: A safety ski binding having an automatic heel release binding which releases when the skier suffers a frontal fall and a front jaw or front release binding which releases when the skier experiences a torsional fall. The automatic heel release binding is secured to the rear end of a release plate connected by means of a pivot pin with the ski and freely pivotable to both sides. The front jaw is anchored in spaced relationship forwardly of the release plate at the ski. At the region of its front end the release plate is provided with two, oppositely situated, substantially L-shaped entrainment elements, attached by one leg to be pivotable about a related shaft at the release plate. In the normal skiing position of the release plate the entrainment elements are retained in their effectual position, by bearing upon the ski, and the other leg of each entrainment element protrudes upwardly from the release plate and bears snugly at the ski boot which has been placed into the safety ski binding.
Abstract: An improved ski, having an upper surfacing material and a lower surfacing material, the two surfacing materials being separated by, and affixed to, a core material throughout substantially the entire length of the ski, the improvement comprising a continuous belt of fiber-glass reinforced laminate bonded to a polyethylene surface layer, which belt forms both the upper and lower surfacing material and which is bent around the core material so that the polyethylene layer forms the bottom running surface as well as the upper surface, the belt further forming an integral guard around the core material of the rear end of the ski.
Abstract: An improved truck or undercarriage for a skate and adapted for injection molding has an elongated plastic body and a pair of traverse plastic axle elements with grooved projections through which mounting bolts extend to flexibly clamp the elements against depending V-shaped projections on the body for limited axle pivoting.
Abstract: A semi-trailer having at its front end at least one landing leg (8) which may be supported in its operative position by a strut (12) which is mounted slidably and pivotally to the chassis by means of a mounting (16) and which leg(s) is(are) raisable by a power unit; the strut(s) (12) may be locked by pin or pins (22) engaging in holes (29, 52) in the strut and the pin(s) latched in at least a partially disengaged position for movement of the strut between the operative position of the leg and an inoperative position, the pin(s) being unlatched to engage in a hole (29, 52) by movement of the strut in the mounting.
