Abstract: A haulm cutting apparatus includes lateral and vertical guiding means or surfaces and a first, rotatable shear rotatable around an axis of rotation extending in a direction with a vertical component. The apparatus further includes a counter shear for cooperation with the first, rotatable shear, and the first, rotatable shear and the counter shear are positioned in a side-by-side relationship relative to a direction of travel during operation.

Abstract: An object is first wrapped with a strip of thermoplastic film such that upper edges of the strip project upward past a top face of the object and fold inward onto outer edge regions of the top face of the object. Then a cover sheet is laid on the top face over the folded-in edges of the strip with outer edges of the cover sheet projecting outward past and hanging down around the wrapped object outside the film strip. A heated plate is then pressed down against the cover sheet and hot air is blown against the strip on the side faces so as to shrink the strip against the side faces and such that the hot air rises and welds the outer cover-sheet edges sheet to the strip around upper regions of the side faces.

Abstract: In order to improve the use of a medical support and compression stocking, it is proposed that the stocking (10) shall comprise a woven- or knitted-fabric-type base element (20) that is substantially tubular and that can be pulled over the lower leg of the wearer. Moreover, the stocking comprises at least one air chamber (30) that can be filled with air. The air chamber (30) is designed in a tubular shape along the length of the support and compression stocking. The stocking further comprises an electronic unit that is equipped with a micropump and a valve for the air supply, the micropump being provided with a valve, a current source, preferably a rechargeable battery and control electronics including a wireless data transfer unit. The pressure values of the at least one air chamber can be regulated by means of the data transfer unit and a software stored in the electronic unit.

Abstract: The invention provides a modular system that includes a composite tile, with or without integrated photovoltaic cells, a track system for assembly of the tiles to a structure, and a wiring system for the photovoltaic tile. The track and tiles are made of composite material. Molding and extrusion processes can be used for the manufacturing of the tile and track, including the integration of photovoltaic cells. The track lengths are fastened to the structure. The track and tile have mating features, such that the tile can be interlocked with the track. Adjacent tiles are installed with overlap. Photovoltaic cells can be molded into or assembled with the tile. A busbar or wire harness is assembled to the track. When the photovoltaic tile is interlocked with the track, the connectors of the photovoltaic cells engage the busbar or wiring harness to provide an electrical connection.

Abstract: The invention provides a charging device that uses switched capacitor voltage converters to charge a battery using solar power. The charger uses boosting topology to efficiently use solar module photovoltaic power. The boosting topology enables a lower voltage to be used resulting in reduced cutting and soldering of photovoltaic cells. The battery charger has overcharge protection and uses inductor-less circuitry.

Abstract: A tie plate is provided for securing a rail to a railway tie. The tie plate has a base with a tie face opposite a rail face, opposite end faces extending between the tie and the rail faces, a gauge side opposite a field side with said gauge and field sides extending between the opposite end faces and the rail and tie faces. A rail support section runs across the rail face between the opposite end faces and along the gauge and field sides. The tie plate further has a respective clip hold down housing adjacent the rail support section on the field side and the gauge side, each clip hold down housing having a rail abutting face proximal the rail support section and a longitudinally extending receptacle for receiving a spring clip. A respective rail locating shoulder extends from the rail face on either side of the rail support section. Locating ridges extend from the tie face for embedding into a tie.

Abstract: A twisted wire tie for concrete forming has an elongate loop with a single strand of wire on one side and a twisted double strand on the opposite side. Two stops on the tie are formed at opposite ends of the twisted double strand and engage the twisted strand and the single strand so as to prevent unwinding of the twisted strand when the tie is placed in tension.

Abstract: A water filter including an inlet assembly which comprises a prefiltering foam tip. The inlet hose includes an adjustable float and a weight on the end of the hose which allows a given length at the end of the inlet hose to extend below the surface of the water being filtered. The water filter further includes a check valve assembly to relieve pressure buildup inside the pump. A unique lever-action handle, in combination with a rocking piston, allows efficient filtering with few moving parts. The filter components are easily replaceable. The main filter assembly is suspended resiliently at its periphery to provide shock-absorbing characteristics. The filter also includes an adaptor base which allows for a direct connect between the vessel into which water is filter. The water filter also provides a unique method of storing the inlet hose to render the water filter easy to carry and prevent foreign objects and debris from entering into the area of working parts.
