Abstract: A bicycle helmet that allows ventilation to a cyclist head. The helmet comprises a hard internal shell, a hard external shell, and a shock absorbing foam insert located between the internal and external shells. The helmet consists of a generally open concave structure having a number of fore and aft extending structural arms, transversely spaced from one another and merging with an annular bottom edge rim at both their fore and aft ends. Each structural arm forms a U-shape in cross-section, for reinforcing the helmet structure. The shock absorbing foam of the insert engages with the grooves formed by these cross-sectionally U-shape structural arms. Air ventilation passages are formed in between each pair of successive U arms, extending through corresponding openings in the shock absorbing insert and through the open mouth formed by the annular internal shell. The radius of curvature of the structural arms is greater than that of the shock absorbing insert.

Abstract: The push actuator has a fixed base which rotatably carries a selectively rotatable rotor. A horizontal band has a lower portion stacked in a helical pattern and has an upper portion engaged by the upper portion of a vertical band, to form a telescopic column. The lower portion of the vertical band is stacked in a spiral, separately from the horizontal band, the horizontal band is supported on the rotor with a helical ball support track along which a number of balls can roll and slide, to allow substantially frictionless rotation of the rotor member while the horizontal band remains rotatably stationary. A ball re-circulation unit allows the balls to circulate between the top of the track and the bottom of the track.

Abstract: The disrupter (16) includes an elongated hollow barrel (18) having a cylindrical inner chamber (20), a closed rear (26) end and an opened front end (22), the latter closed with a front frangible seal (38). A channel member (46) partly surrounds an intermediate portion of the barrel, and is securely attached thereto. A pair of recoil channels (76, 78) extend from the barrel inner chamber, radially outwardly and rearwardly through the barrel and the channel member, and are linked to rearwardly oriented recoil tubes (52, 54) which have opened rear end portions (60, 62) closed with rear frangible seals (64, 66). In use, a cartridge (90) including an explosive charge (88) is to be inserted in the barrel inner chamber at its rear end, and the barrel, recoil channels and recoil tubes (52, 54) are to be filled with water. The frangible seals (38, 64, 66) prevent the water from leaking out of the disrupter while it is positioned near a bomb to be deactivated.

Abstract: The exerciser has a pair of arcuate posts having lower footrests for resting on the ground, and a U-shape spacer bar, mounted to the top ends of the arcuate posts for free abutting against an upright wall. The two posts therefore remain substantially parallel to each other and to the upright wall. The posts are provided with notches distributed along their length, in a horizontally registering pair of which a push-up bar may be inserted for support of the push-up bar at a selected height over ground. The exerciser takes minimal ground space, yet allows may different types of exercises to be performed by an individual.

Abstract: The power generator unit includes a container having a peripheral wall enclosing a power generating motor assembly.

Abstract: A conveyor conveys palletized articles to a loading dock. A bogie movable along rails between different loading docks, supports an independently movable carriage, which may roll out of the bogie once the latter reaches a desired loading dock. The carriage then loads with a forklift provided on the carriage, the articles from the conveyor into a semi-trailer located at the loading dock. The carriage is provided with a linkage pivotally installed on its main frame, the linkage carrying four lateral guide wheels which protrude laterally beyond all other structural elements of the carriage. The linkage integrally links the guide wheels into a common pivotal displacement, with the guide wheels remaining symmetrically disposed relative to the carriage frame. A hydraulic piston biases the guide wheels towards an outer limit position at all times, and the guide wheels are forcibly pivotable, against the bias of the piston, towards an inner limit position.

Abstract: A continuous thermoplastic wire is heated and fed into a coil forming apparatus having a rotative drum holding an injection nozzle so that it registers with and be linked in a common rotative movement to a threaded mandrel also supported by the drum. The wire discharged by the nozzle slidably engages the threads of the mandrel into a helical pattern, the mandrel being radially and coaxially surrounded by a cooled sleeve. The wire will thus solidify along the helical thread of the mandrel, to form a continuous plastic coil being discharged at the downstream extremity of the mandrel and sleeve assembly. Due to the fact that the drum, mandrel and nozzle all rotate in a common rotative movement, it is possible to select the direction and speed of rotation of the three last-mentioned elements so that the coil being discharged have an ouput discharge translational speed, while being exempt of any absolute rotational movement about its longitudinal axis.
