The rectangular frame is supported on the axle between two wheels by upright members pivotally connected to the two sides of the rectangular frame near the center. A handle extends from the axle and is joined to the rectangular frame at one end of the frame. The point of connection can be moved along the handle away from the axle to rotate the upright members to a folded position. Legs attached to the rectangular frame prevent tipping about the axle and wheels. The legs can be folded upwardly against the bottom of the container to fold the bottom of the container against the rectangular frame.

Abstract: A motor vehicle speed-control system includes a bellows chamber having a movable wall connected to the engine throttle. The pressure of the gas in the chamber is controlled by two electromagnetic valves, the first electromagnetic valve being energized with electrical pulses to repetitively connect the bellows chamber alternatively to atmosphere and vacuum, and the second electromagnetic valve being spring-biassed so that, when deenergized, it vents the chamber to atmosphere to ensure rapid closure of the throttle, and when energized, closes the said vent. An auxiliary fail-safe brake-pedal valve is provided. An audible signal is produced by a flow of air in the event of malfunctioning of the actuator device.

Abstract: An improved base construction for a wheeled nestable shopping cart is provided by forming the base primarily from two U-shaped members. The first U-member has a planar portion disposed directly under the basket for supporting same, which portion terminates in downwardly directed rear legs which have the lower ends thereof joined to the rear wheel assemblies. The second U-member has the bight thereof forming the toe end of the base. The leg portions of this second member incline rearwardly and upwardly from the bight such that the free ends thereof are fixedly engaged with the rear legs adjacent the upper ends thereof. Side braces rigidly join the planar portion to the leg portions of the second member. This arrangement effectively prevents storage of goods on the base.

Abstract: An assembly intended to eliminate the turbulence and pressure rise occurring inside a mudguard (1) due to the effect of the airflow, caused by the motion of the vehicle, passing over the inside of the mudguard and meeting the counter-directed airstream caused by rotation of the wheel (2) and the splash formed thereby. By introducing guide means (3,4) between wheel (2) and mudguard (1), these streams of air can be mutually separated and the wheel airstream redirected to coincide with the airflow on the inside of the mudguard without pressure rises and consequent turbulence occurring inside the mudguard. The assembly can have one or more vanes (4) or a body (3) forming a portion of a channel (9a,9) for the airflow along the inside of the mudguard and simultaneously redirecting a portion of the wheel airstream.

Abstract: A ski brake having a support plate secured to a ski and a combination of a support member and an operating plate pivotally secured to the support plate, which support member and operating plate pivotally support the brake arms therein for movement between a retracted position above the upper surface of a ski and a braking position wherein the brake arms extend beneath the lower surface of the ski. The pivotal movement of the support member and operating plate relative to the support plate, as well as the pivotal movement of the brake arms relative to the support member and the operating plate, is accomplished by a single spring.

Abstract: A safety system for motor vehicle steering lock incorporated in an ignition switch and including a steering lock bolt displaceable between a retracted position which it occupies when the ignition key is in the lock, and an extended position which it occupies when the ignition key is removed from the ignition switch. The safety system operates to lock the bolt in its retracted position whenever the vehicle is in motion, either by locking the ignition switch to prevent removal of the key or by directly engaging the bolt so that it cannot be displaced to the extended position even if the ignition key is removed from the ignition switch when the vehicle is moving. A detector device senses when the vehicle is in motion and supplies a signal to an electromagnet to effect locking.

Abstract: A ski pole having a detachable coil spring disposed substantially centrally whereby a top portion and bottom portion of the ski pole may be detachably connected to the ends of the coil spring. The coil spring is of such stiffness as not to flex during normal operation of the pole during skiing. However, on application of abnormal bending force to the pole, the coil spring will flex sufficiently to prevent permanent bending or breaking of the pole. The handle of the ski pole may also be detachably secured to one end of a stiff coil spring, the opposite end of which coil spring is detachably secured to the top end of the ski pole so that the spring will not flex during normal operation but will flex upon abnormal bending applied to the handle to prevent hand injury to the skier.

Abstract: Apparatus for attaching to a snow ski includes a retractable member for extending beyond the edge of the ski to provide a semi-circular engaging surface that a ski pole can be butted up against. The apparatus allows a skier to easily maintain his position on a slope or secure the position of one ski while moving the other forward to a new position. The apparatus is also balanced along the longitudinal axis of the ski so that when the member is retracted the skis are balanced along the longitudinal axis.
