Abstract: A self supporting grate for a drain structure can be improved by including as part of the grate a mounting base sized and shaped to attach the grate to the drain structure. At least a portion of the grate is formed as a generally upwardly projecting wall attaching to and extending from the base. The wall includes a plurality of weirs capable of forming a variable flow fluid pathway to the interior of the grate for fluid disposal by the drain structure. The weirs are constructed so as to allow fluid at a first fluid level on the wall as measured from the base to flow at a first rate from the exterior of the grate into the interior grate and fluid at a second fluid level likewise measured along the wall from the base to flow at a second rate into the interior of the grate, with the second rate being different from the first rate. A guard lip is located on the mounting base peripheral to the grate to retard the flow of solid material over the guard lip and to prevent clogging of the grate.

Abstract: A toy arcade game has a housing with a motor located therein. The motor is connected via various drive trains to move a target through a target field, a target coordination member, and an attack mechanism including an attack coordination member. The target coordination member moves between an interaction position when the target is in its hit position and a non-interaction position when it is not. Under the influence of an initiator member the attack coordination member moves from a non-interaction position to an interaction position and back again to the non-interaction position. An interaction member is mounted on the housing to move from a first position to a second position when both the target coordination member and the attack coordination member are simultaneously in their respective interaction positions. An indicating mechanism located in the housing is capable of producing a sensory perceivable output, inter alia, in response to location of said interaction member in its second position.

Abstract: A rocking scale or weighing device can be constructed so as to include a body equipped with two separate, spaced, identical bowed supports or rockers which extend generally between the ends of the body. A holder capable of holding an envelope or the like perpendicular to the body is located at one of the ends of the body. Guides are provided on the body for use in holding a counterbalance member so that it may be moved towards and away from the holder. Indicia are provided for indicating the weight of an object held by the holder by the position of the counterbalance member on the body. Detents may be provided for use in temporarily securing the counterbalance member in a specific position.

Abstract: A magnetic recording disk is constructed wherein a disk substrate is overlayed with at least one non-recording layer. A recording layer is then overlayed on the non-recording layer with the thickness of the recording layer at those areas corresponding to the inner track zone located toward the central hub area of the disk being thinner than the intermediate track zone radially displaced outwardly from the inner track zone toward the periphery of the recording disk.

Abstract: A toy has a front body and a rear body which are connectable directly to each other, or connectable to each other utilizing a third body, such as a pencil or the like. Both the front and the rear bodies include appendage members which contact a support surface and allow the unified front and rear bodies or combination of the front and rear bodies and the third body to move across a support surface in a walking-like motion by individual movement of the appendage members. The appendage members on the front body are driven by a motor located in the front body to move the toy across the support surface, whereas the appendages on the rear body are moved in response to movement of the rear body by the front body.

Abstract: A toy which can be assembled in a non-permanent manner has a body which includes a first and second body section. Each of the first and second body sections includes a mating face. The mating face on each of the body sections is complementary to the mating face of the other body section, such that the sections can be positioned in association with one another by juxtaposing the respective mating faces. A motor capable of producing an output is held in a motor cradle formed in part in one of the sections and its remaining part formed in the other of the sections. The sections are maintained together utilizing a fastening mechanism which includes one of the sections having an opening in its mating face and the other of the sections having a first joining member which is capable of passing through the opening and a second joining member capable of frictionally engaging the first joining member.

Abstract: A device for organizing papers, files and the like for use in a business environment or other similar situations has a base on which one or more tilt plates are located. The tilt plates are capable of being oriented with respect to the base in a tilting mode and in a locked mode. In the tilting mode the tilt plates rotate about a bottom edge to tilt forward and backward. In the locked mode, the tilt plates are fixed in a set orientation with respect to the base. The tilt plates are easily shifted between the tilt mode and the locked mode by simply sliding them sideways a short distance on the base. Tabs on the bottom of the tilt plate maintain the tilt plate on the base and interact with a stop and lock member on the base to determine which of the modes the tilt plate is in.

Abstract: For use with a self-propelled object, a toy can be formed having a housing with a playing surface located thereon. The playing surface includes a circular depression having a member rotatably mounted in the circular depression and capable of rotating in the circular depression. An element and gear train are associated with the member to rotate the member in response to movement of the element. The member includes a surface which is in alignment with the playing surface such that the self-propelled object can be located on the playing surface and directed toward the member. When the object moves itself onto the member, the member is rotated, allowing the object to move off of the member in a different orientation with respect to the playing surface. A retaining rib is formed on the playing surface adjacent to the periphery of the rotatable member and partially surrounding it to inhibit movement of the object. Scoring depressions deep enough to retain the object are formed in the playing surface.
