Abstract: A hand-pushed mower of which blade height setter is provided with a sphere rolling on the ground, many small spheres holding the sphere as to freely roll, a semi-spherical receiving member forming a gap between an upper spherical face of the sphere to hold the many small spheres in the gap, and a scraping ring frame portion disposed to be parallel to and having a predetermined interval with a lower end edge of the semi-spherical receiving member. The scraping ring frame portion is disposed to be near the surface of the sphere as to scrape foreign matter on the surface of the sphere. A window portion for removing the foreign matter is formed between the lower end edge of the semi-spherical receiving member and the scraping ring frame portion.

Abstract: A caster device is disclosed for movably supporting a load. The caster device includes a wheel for supporting the load and a wheel support having a first and a second extremity. The first extremity of the wheel support supports the wheel for rotation of the wheel about an axis of rotation. The second extremity of the wheel support defines an aperture and the wheel support has a first surface and a second surface. A support stem has a first and a second end, the support stem extending through the aperture such that the aperture is disposed between the first and the second end of the support stem. The second end of the support stem is connected to the load for supporting the load. Also, a leaf spring is disposed between the aperture and the second end of the support stem such that the leaf spring resiliently contacts the load and cushions the load relative to the wheel.

Abstract: The safety support device of this invention includes a frame having a mounting section. A pair of forward legs are attached to a forward end of the mounting section and a pair of rear legs are attached to a rear end of the mounting section. Each leg has a distal end to which is attached a roller assembly that includes a roller member mounted so that with the weight of the user bearing down on the assembly the roller member is prevented from moving. In a second embodiment used to assist injured or elderly person stand erect, the legs are long and arm support members engage the arm pits of the user when the user is being supported by the device.

Abstract: The necessity for spontaneously transmitting each individual wager from a remote terminal or terminals to a host computer in a computerized lottery system is completely eliminated. As a result, the total amount of data transmitted between the remote terminals and the host computer is substantially reduced. This reduces the consequent cost of transmission and enhances the number of economically viable transmission alternatives. A total number of sequential plays is conveyed from the remote terminal or terminals to the host computer. Pseudo-random wager numbers and serial numbers associated with each of the plays is reconstructed at the host computer from the total number of sequential plays. The reduced data exchange facilitates novel methods of data transfer, such as satellite packet transmission and cellular service.

Abstract: A dual roller assembly adapted to simultaneously rotate along perpendicular surfaces. The roller assembly comprises a pair of telescopically engaging shaft members sized to rotate and move axially of one another. A first of the shaft member, mounts first and second interfitting cylindrical members receiving a rotary caster ball, where the rotary caster ball is supported for rotative movement within the roller unit formed by the interfitting cylindrical members, by a first ball bearing ring. The second shaft member mounts a cylindrical cap member for receiving a second ball bearing ring in rotary contact with the second cylindrical member, and finally, the second shaft member further mounts a fixed annular ring spaced from the cylindrical cap member, and an encircling compression spring on the second shaft member extending between the cylindrical cap member and the annular ring, to provide shock obsorbing features thereto.

Abstract: A grommet (1) is provided for sealing an opening in a panel, through which at least one cable passes, comprising a tapered hollow body which sealingly engages the cable at least at a first end (10) and the edge of the opening via a groove (30) formed on a second end (20), wherein at least one means for reducing stiffness, in particular a recess (12, 14, 16) is provided on an inner surface (5) and/or on an outer surface (6) of the hollow body, so that elastic deformation of the grommet (1), in particular of its second end (2) is facilitated.

Abstract: The Global Force Caster, acting as a multi-directional unhindered wheel permits an object, i.e. furnitures, shopping carts, mobility aids etc., resting on the global Force Bearer's threaded casing or in bored hole in the object's body, with instantaneous movements at will in any direction upon a negligible external lateral force without the jerking movement or hinderance of delays due to a dispositioning of the wheel in relation to the direction of the external lateral force, commonly found in conventional wheels assemblies. Additionally, the "Bearer" is free of extra efforts needed when a change in direction is unavoidable when changing elevations, as opposed to the typical wheel assemblies.

Abstract: A ball joint assembly comprising a base member, a spherical member, a ring of at least three rolling members mounted around the spherical member such that a point on a rolling surface of each of the at least three rolling members contacts a point on a first great circle on the surface of the spherical member, the ring of rollers being freely rotatable around the axis of the first great circle, at least two capture rolling members, one capture rolling member being mounted such that a rolling surface of the one capture rolling member is in contact with a point on the surface of the spherical member above the plane of the first great circle and another capture rolling member being mounted such that a rolling surface of the other roller member is in contact with a point below the plane of the first great circle.

Abstract: There is disclosed a weight transfer roller apparatus including a barrel type housing formed on one extremity with a radially inwardly projecting retaining flange forming a circular protrusion opening. A roller ball is received within the bore of such barrel, has one side projecting from such opening, and has its opposite side nested on an annular high lubricity plastic ring formed with a bearing seat defining a sector of a sphere corresponding with the spherical roller. The annular bearing ring rests on a retainer secured to such housing whereby the housing may be mounted in a weight transfer platform and loads passing thereover will weight downwardly on such ball to be carried by the bearing ring. Preferably, the ball, annular bearing ring, and retainer are telescopically received in the bore of the barrel with the retainer being selectively removable for removal of the bearing and ball for replacement thereof upon deterioration or damage.
