Abstract: The moldboard support assembly for a motor grader reinforces the rear face of the moldboard by a series of vertical ribs. Upper and lower slide rails are secured to the ribs at a position outwardly of the rear face of the moldboard. This produces a series of gaps between adjacent ribs and between the rear face of the moldboard and the slide rails. These gaps allow material to clear away from the slide rails and thereby reduce bearing contamination of the slide rails.

Abstract: A car or other vehicle is prevented from crashing through a barrier along a driveway or other path. One or more bollards stands in the path, on a support in a recessed box that is flush with the surface and defines a pivot axis perpendicular to the path of the vehicle. The bollard can be temporarily detachable to permit passage. A vehicle striking the bollard pivots the bollard backward on the axis, preferably into a clearance space provided. Elongated pike structures are coupled to the bollard and are pivoted up from the surface at an acute angle, to pierce and arrest the vehicle. The pikes can be structural bars, for example of angle iron with flanges formed to barbed points. Preferably several pikes are provided, of which some are angularly fixed relative to the bollard and others are rotatable up to a maximum angle at which the pikes become angularly stopped, for example by engagement with the adjacent pikes. The pikes thus are deployed in a bristling array that engages with the vehicle.

Abstract: A cultivator shovel for mounting on one of the shanks of a conventional agricultural cultivator. The shovel includes a shank mount in the form of a channel for receiving the shank therein. A shovel body is supported on a lower end of the shank mount and includes a leading edge extending rearwardly and outwardly from opposing sides of a forward apex to respective rearward free ends of the shovel body. A pair of upright end plates are mounted on the shovel body adjacent the respective rearward free ends. The end plates prevent deflection of weeds about the free ends of the shovel body when the shovel is used for weeding, thus forcing the weeds to be broken on the leading edge of the shovel body or on the end plates for more effective weeding using a cultivator. Furthermore, soil disturbance is increased dramatically using the end plates, and as a result, shallow rooted weeds such as millet die.

Abstract: A corner support element for paving slabs has stackable plate elements to facilitate transport and for height adjustment. The guide and support elements for corner parts of paving slabs, namely plate elements, have cruciform upright support and distance providing projections. The projections are shaped as upwardly tapering elements with open cavities downwards for accommodating corresponding underlying projections. The elements are modular and can be separated along radial rows of projections to form semicircular segments for supporting two adjoining slab corners or quarter segments for supporting only a single corner. The elements are stacked in columns without turning each of the modular parts mutually between them.

Abstract: An adjustable manhole cover frame assembly suitable for mounting on a manhole basin upper section has an outer ring, capable of resting on the top surface of the upper section, and an inner ring engaging the outer ring by screw threads and having support for a manhole cover. The lower surface of the frame assembly has a part spherically curved surface resting on a similarly curved surface of the manhole basin upper section and which allows the orientation of the frame assembly to be adjusted. Also, the frame assembly itself may have parts with part spherical mating surfaces allowing an upper part to be adjusted for slope when the remainder of the frame assembly has been fixed.

Abstract: A motorized ice breaking apparatus has a housing with a power source connected thereto. A drive train is operatively connected to the power source. The drive train includes a drive shaft with a crank. A blade is disposed on a bottom side of the housing and extends laterally from a first side to a second side of the housing. A connecting rod is pivotally connected to the blade and pivotally connected to the drive shaft's crank. A pair of guide channels is connected to the bottom of the housing, one guide channel being proximate each lateral side. Ends of the blade are slidingly engaged in corresponding ones of the guide channels. The power source rotates the drive shaft and imparts a reciprocating motion to the connecting rod through the crank. The reciprocating motion of the connecting rod reciprocates the blade in a substantially vertical motion.

Abstract: A snow groomer includes a movable platform, a prime mover mounted to the platform and a grooming drum rotatably driven by the prime mover for rotation in a direction opposite the traveling direction of the snow groomer. The grooming drum includes axially spaced apart and radially protruding ribs that extend circumferentially around the drum. The ribs include circumferentially spaced apart apertures and the apertures of each rib are aligned with the apertures of the other ribs. Elongated cutting teeth extend through the apertures of the ribs and have a cross-sectional area that is smaller than the apertures such that the cutting teeth are free to vibrate within the apertures as the drum rotates, thereby enhancing the pulverization of chunks of snow and ice.

Abstract: A protection barrier system for energy-absorption of impacts includes an elongated barrier defining a chamber therein. The barrier includes side walls having a plurality of connected non-vertical wall segments and a plurality of buttresses positioned vertically at spaced apart locations along each side wall. One or more guide channels are positioned on each side wall in horizontal alignment with similar guide channels on like-configured barriers. A coupling is disposed on each opposed end of the barrier for coupling of either barrier end juxtaposed in end-to-end nested arrangement with like barriers. A supplemental energy-absorbing system is connectable between opposed ends of end-to-end coupled barriers, providing energy-absorbing tubes removably inserted through each guide channel of each barrier. Cables are extendable through the tubes in the guide channels of the nested barriers, providing additional energy-absorption and deterrence from breaching of the barriers.
