Abstract: A multi-level window shutter has a shutter frame movably supporting at least one first level external shutter panel via an external panel opening mechanism mounted on the shutter frame. The external panel movably supports at least one second level internal shutter panel via an internal panel opening mechanism mounted on the external panel and connected to the shutter frame and to the internal panel for simultaneous displacement of the internal panel upon displacement of the external panel relative to the shutter frame. The panels move between a closed position in which they are in a side-by-side configuration relative to one another in spaced apart parallel planes and an open position in which they are in an over-one-another configuration relative to each other in the spaced apart parallel planes.

Abstract: A rotary plant growing apparatus has a cylindrical structure rotatably mounted on a support base. The cylindrical structure consists of a plurality of baskets in which plants may be grown and rotates around a rotational axis such that the baskets are at least partially immersed in nutrient reservoir containing a liquid nutrient for nourishing the plants. A light source extending at least partially through the cylindrical structure provides light for growth of plants. The baskets are securely and removably attached to rims of the cylindrical structures by pins extending therefrom and which have heads which retaining the pins in apertures therefore on the rims. A motor and gear arrangement provides rotation of the cylindrical structure.

Abstract: A wheel spacer is provided for spacing a reinforcing rod for a cementitious structure away from an object during fabrication of the structure. The spacer consists of two substantially semicircular sections configured for connection together with the rod abuttingly retained in saddles generally situated at the center of the sections when connected together in an assembled configuration for the spacer. Each section has, on an inner wall thereof in which the saddles are situated, primary inserting arms for insertion into apertures for locking engagement with teeth on the inserting arms with teeth on receiving arms of the other section. Retaining arms having guide walls further facilitate retention of the rod and guiding thereof towards the saddles while the spacer is placed in the assembled configuration.

Abstract: An improved building panel is presented to make wall surface assemblies on structural building frames. The edge-sealed building panel includes with self-aligning features between adjacent horizontal edges for quick mating and assembly. The building panels have protuberant upper edges mate with grooves on the lower edges for improved sealing and weatherproofing, due to the interlocking shape and the use of compliant seals between the edges. The horizontal mating edge shapes enable pivoting assembly by engaging the building panel obliquely and swinging it onto the wall surface. Vertical mating surfaces with compliant seals are shaped to engage perpendicularly to the wall plane, so that the compliant seals clamp shut without in-plane relative motion, improving seal integrity.

Abstract: A windshield wiper snow removal and deicing device raises a windshield wiper blade away from a windshield, upon which the blade is otherwise maintained in contacting engagement therewith by a wiper biasing spring connected to the wiper arm, such that the blade falls down and impacts the windshield to remove snow and ice accumulated thereon while wiping on the windshield. In a first embodiment, a motor connected to the arm rotates a flap connected thereto to raise the blade above the windshield. In a second embodiment, a cover for a casing attached to the windshield is raised into an idle deployment configuration for engaging the arm and raising the blade above the windshield. In a third embodiment, a body on the arm has a pivoting member to engage an engagement stop on the windshield, with the pivoting member pivoting into a vertical configuration to lift the blade off the windshield.

Abstract: A board for opening an oyster has a cradle consisting of a support wall and a cradle portion sloping upwardly therefrom. The outer wall supports and anchors first end portions of the oyster which rest in abutment against, while the second end portions are disposed and elevated slightly on the cradle portion for opening of the oyster at the second end portions.

Abstract: The present invention provides an illuminated decorative item, a decorative item made of ribbon and an illumination circuitry for a decorative item made of ribbon. The illuminated decorative item comprises a decorative body created with at least one elongated strip of material, the body having a base; a light source disposed at the base; an energy source electrically connected to the light source to supply energy to the light source; and at least one optic fiber, each optic fiber comprising an elongated body having a base end and a free end, the base end being close to and oriented towards the light source, the free end being arranged to visually complement the decorative body; wherein the energy source supplies energy to the light source, at least some light emitted by the light source enters the optic fiber at the base end, propagates inside the optic fiber, and exits from the free end thus generating an illumination at the free end and creating a illumination effect for the decorative item.

Abstract: A toothbrush (1) including a handle (15) and a brushing head (2) with two brushing compartments (3, 4). The upper brushing compartment (3) is engageable by the teeth of the upper jaw and the lower brushing compartment (4) is simultaneously engageable by the teeth of the lower jaw. The handle of the invention can be pivotably mounted (16, 18) on an outer wall (17) of the brushing head.

Abstract: An electromagnetic motor includes a permanent magnet connected to a piston component of the motor and defining a linear reciprocating displacement path; and two electromagnets connected to the cylinder housing that periodically and alternately interact with the permanent magnet. The electromagnets are electrically connected to a power source for their selective activation. The electromagnets magnetically attract the permanent magnet over a respective first portion of the displacement path when un-activated and magnetically repulse the permanent magnet over a respective second portion of the displacement path when momentarily activated by the power source.

Abstract: A hand tool device incorporates a fluid operated mechanism actuable by a plunger pressurizing a reservoir to force fluid past a resiliently biased valve to a fluid filled cylinder accommodating a piston carrying a contact member for clamping a work piece in the manner of an adjustable wrench or pliers. Continued operation of the plunger increases the pressure applied to the work piece.

Abstract: An auxiliary vacuum device for a central vacuum cleaning system is location specific and comprises a housing mountable externally on an inlet of a mounting plate of the system, a dedicated flexible concertina hose is provided on the device and a cleaning tool mounting probe is registrable with a docking station. With the probe docked in the docking station the device is in the ‘off’ position and with the probe removed therefrom the device is in the ‘off/standby’ mode. A push on/off button is used to complete the procedure for starting the system and for stopping it in an ‘off/standby’ mode.

Abstract: A single leg support for sitting on by a user has a seat member adjustably connected to a post member, with the post member connected to a base member which contacts a ground surface. In typical use, the support axis of the support is between about five and twenty-five degrees relative to the vertical such that the user remains in equilibrium with most of his/her weight supported by his two legs at about five degrees from the vertical with the knees slightly bent. Thus, the support carries only a small portion of the user's weight for increased comfort. The support is adapted to be fitted into a bicycle. Additionally, the support may be used with a heavy base member having a flexible joint allowing rotating movement of the support while a user is seated thereon.
