Abstract: The present invention is a stabilizing strap for a cyclist helmet which comprises two flexible elongated strap members which are adjustably and releasably attached at their first end to the interior surface of the helmet rim portion, at the rear end of the helmet, by means of hook and loop fasteners. The strap members are adjustably and releasably attached at their second end to one another also by means of hook and loop fasteners. The curved strap is destined to bear on the occipital bone of the head, to prevent the helmet from accidentally tilting frontwardly, especially as a result of an impact. The flexibility and the several adjustments of the stabilizing strap allow it to fit heads of different sizes and shapes.

Abstract: The present invention relates to a tray for carrying a plurality of pallets loaded with several concrete blocks. The tray is a rectangular frame defining an upper surface, front and rear ends and upwardly-projecting flanges at both front and rear ends. The tray is adapted to receive the loaded pallets on its upper surface between the flanges. The invention further relates to a system adapted to carry the loaded tray through a block curing kiln. The kiln is composed of a plurality of longitudinal cells, as is already known, and the pallet-loaded trays are inserted in a consecutive linear abutment fashion in the cells. The relatively high flanges of each tray thus abut on one another, which prevents the overlapping of the trays, and thus prevents the damaging in this way of the concrete blocks.

A tubular coupling member has an inner end portion of a shape complimentary to that of the top wall of the collector box, for releasable interlocking engagement therewith, and an outer end portion, for releasably coupling with a complementary flexible air suction conduit for discharge of the lint to a waste container. The chute consists of: an elongated tube, having an enlarged transversely opening mouth at one end, and a smaller axially opening outlet port at the opposite end.

Abstract: The invention discloses a humidifying device which consists in a thermally conductive casing which is adapted and correctly dimensioned to fit over a conventional electrical radiator without preventing it from heating the ambiant air simultaneously. The casing is destined to be at least partially filled with water, and upon the radiator generating heat, the water temperature will gradually increase and water will evaporate into the ambiant air through outlets in the top of the casing due to the heat being conducted through the radiator and casing to the water. The water vapor outflow rate can be selectively adjusted by means of a pivotable heat deflector or alternately by adjusting the distance between the radiator and the casing. A sponge member filled with bactericide is inserted into the casing and is submerged in water.

Abstract: A swing arm is pivoted to the pedal housing of the bicycle frame and extends rearwardly from the seat post. The rear bicycle wheel is carried by the rear end of the swing arm. A follower is guided and is moveable along the seat post for up and down movement. A brace arm interconnects the swing arm rear end and the follower and an elastic tension cord biases the follower towards the pedal housing. The bicycle has also a front suspension. The front wheel carrying fork of the bicycle is telescopic and upward movement of the front wheel causes elongation of an elastic tension cord. A stabilizer system is also provided whereby upward movement of the front wheel causes upward movement of the rear wheel and vice and versa. Finally, a damper prevents any up-and-down oscillation of the bicycle frame.

Abstract: This jig-saw puzzle holder comprises two co-extensive work panels hinged together at their inner edges to take a closed folded position and an open coplanar position with their inner edges forming a smooth joint. A liner sheet covers and is secured to the panels and serves as a work surface upon which puzzle pieces can be assembled. To each panel is associated a generally co-extensive flexible cover sheet to cover puzzle pieces on the liner sheet. The liner and cover sheets are hook-and-loop fastener fabric so that the cover sheets can adhere to the liner sheet to surround the partially assembled puzzle pieces and thus prevent shifting of these pieces. When the pieces are being assembled, the cover sheet is rolled up and retained in an out-of-the-way position. Each panel is provided with a drawer to store individual puzzle pieces. Each panel is used to assemble half of the completed puzzle and the two halves are assembled across the smooth joint of the two open coplanar panels.

Abstract: The scaffolding comprises a post having a plurality of vertically aligned and equally spaced studs protruding on one of its surfaces. A frame supporting a work platform can move along the post, a sleeve being attached to the frame for guiding it along the post. The sleeve, the frame and the work platform partially surround the post. A lifting apparatus, installed on the sleeve, comprises a rotatable endless screw which is parallel to the post and which has a peripheral and helical flange which bears on the studs. An engine, an electric power drill or a manual handle will rotate the endless screw via one or two speed reducers. The rotation movement of the endless screw will result in the axial displacement thereof along the post, carrying the frame and work platform along with it. Another embodiment of the invention comprises a work platform which is supported at both of its ends by a lifting apparatus movable along a post.

Abstract: The protective fence of the invention comprises a first and a second arms that are pivoted at the opposite ends of a frame member that is placed in lieu of the bumper of a school bus. When children are entering or exiting the school bus, the bus driver can activate the arms that alternately pivot into an outwardly-projecting extended position. The arms are linked at their outer ends by a foldable band that is stretched between the two arms. The area directly in front of the school bus hood is circumscribed by the arms and the foldable band, and is thus not readily accessible by any of the children. Consequently, it is much less likely that a child will stand in this area in front of the school bus hood when the bus driver drives off, and disastrous accidents can be avoided.

Each lens element: is of generally spherical shape; is thickest in its center portion and gradually thinner towards its edgewise portion to control the optical distortion brought about by a curved plastic lens; is adapted to register with a corresponding one of the two eyes of a wearer; defines an interior surface in facing register with the wearer's face and an exterior surface; includes an inturned web interconnecting the top and inner sides of each lens element to the lip and bridge part, respectively, the lens element being outwardly offset relative to said lip and bridge part.

Abstract: A suction source is connected to the upper end of a vertical suction tube; a plug member slides upwardly within the tube under the action of the suction source and moves down by gravity when the suction source is cut off The suction tube has a bypass port above the plug member and a valve is operated by the movement of the plug member to close and open the bypass port when the plug reaches its lower and upper limit positions respectively. Therefore, the plug continuously reciprocates up by suction and down by gravity upon sequential closing and opening of the valve. The system is incorporated in a central vacuum cleaning apparatus which provides the suction source and has a filter. The reciprocating movement of the plug drives a hammer or brush to continuously remove the dirt accumulating on the filter.

Abstract: The window unit of the invention comprises four peripheral channel members linked with corner members to form a window frame. Two glass panels are spaced by this frame to form an inner chamber, the louver blind structure of the invention being located completely therein. The louver blind structure comprises a plurality of horizontal slats pivotally supported at both their extremities and each having an integral toothed wheel engaging a complementary rack on an actuator bar, the latter positioned adjacent to a side peripheral channel member and being free to move upwards or downwards along it. This upward or downward movement imparts a pivoting movement to the slats. The louver blind structure further comprises a support channel member supporting a reversible electrical motor having a driving shaft. This shaft has an eccentric stud which engages the actuator bar and must therefore be kept properly alined so as to resist radial forces exerted thereon.

Abstract: The compound of the invention comprises a combination of four ingredients: a superabsorbent polymer, particularly sodium polyacrylate; a chemical disinfectant, particularly potassium peroxymonosulfate; an organic deodorant, particularly from herbal extracts; and a chelating agent, particularly malic acid.
