Abstract: Rotating door systems and methods for rotating a plurality of rotatable doors between a closed position and an open position are provided. Each of the rotatable doors may have a height measured in a vertical direction between opposing horizontal edges, a width measured in a horizontal direction between opposing vertical edges, and an axis of rotation centrally located between the opposing vertical edges. The rotatable doors may be rotatably coupled to an upper support at the axis of rotation via an upper pivot shaft and rotatably coupled to a lower support at the axis of rotation via a lower pivot shaft. The rotatable doors may be at least partially transparent. The rotation of one or more of the rotatable doors may be controlled by a controller.

Abstract: The present invention is applicable to the technical field of decoration tools and provides a chisel. The chisel comprises a housing; a first guide device arranged in the housing; and a cam mechanism disposed in the housing, wherein the cam mechanism comprises a first end cam and a second end cam which are fixedly connected together and have cam end faces opposite to each other, a connecting device connected with a power device is arranged on one side, opposite to the cam end face, of the first end cam, and the second end cam is a hollow cam; a hollow portion capable of passing through the second end cam, wherein the hollow portion is in contact with and matches the cam end faces of the two end cams, to drive a driven member for movement of a chisel body.

Abstract: The present invention discloses an electric chisel capable of being matched with a domestic electric drill to be used. The electric chisel comprises an electric drill, a casing, a push rod and chisel head mechanism and a groove cam mechanism. The top of the casing is provided with an oil hole, and a rubber plug is arranged on the oil hole to be used for preventing dust; the two ends of the groove cam mechanism are provided with a first bearing and a second bearing respectively, and a first groove and a second groove are formed below the first bearing and the second bearing respectively and positioned in the inner wall of the casing. The groove cam mechanism is provided with a groove, and the push rod and chisel head mechanism is connected with the groove cam mechanism and performs reciprocating motion up and down in the groove of the groove cam mechanism.

Abstract: A casket assembly comprising a coffin base, an outer decorative casket configured to conceal the coffin base, a first support leaf, and a first operating handle. In one embodiment, the coffin base has a first side and a first ledge projecting outwardly from the first side. The outer decorative casket has a first panel and a first support leaf having first and second edges. The first support leaf is hingedly coupled along the first edge to the first panel and is configured to rotate around the first edge between a stowed position and a coffin-support position. In the coffin-support position, the second edge is proximate an underside of the first ledge. The first operating handle is coupled to the first support leaf and configured to positively lock the first support leaf in the stowed position or the coffin-support position. A method of manufacturing a casket assembly is also provided.

Abstract: A height of cut adjustment system for a reel type grass cutting unit includes adjustment screw mechanisms mounted at each corner of the cutting unit. Linkages between the adjustment screw mechanisms permit driving all of the adjustment screw mechanisms synchronously from a single adjustment point to change the cutting height. The linkages may be worm gear drives or other mechanical linkages.

Abstract: A rotor for a permanent magnet motor includes a rotor body and a plurality of permanent magnets carried by the rotor body. The rotor body has an outside rotor surface with a plurality of dovetail slots formed on the outside rotor surface. Each magnet is fit within one of the slots, protruding outward of the outside rotor surface in a radial direction. According to another embodiment, a rotor is provided having a rotor body that carries a plurality of magnets on its outside surface, and end caps that are fastened respectively to longitudinal ends of the rotor body. The end caps each have a angled rim surfaces that overhangs an end portion of the outer magnet surface of each of the magnets to retain the magnets onto the rotor body. The angled rim surfaces and the magnets can be configured such that by drawing the end caps tightly against the rotor body by use of fasteners, the magnets are wedged down onto the rotor body by the angled rim surfaces.

Abstract: The invention provides an electric motor drive for a reel mower. The drive includes an electric motor, a casing, an endless traction member and a secondary output shaft. Preferably the electric motor is a brush-less permanent magnet type electric motor. The electric motor includes a rotor, a stator, and a motor housing that carries the rotor and stator, the rotor having a rotor output shaft extending from the housing. The casing is mounted to the motor housing. The endless traction member is engaged to the rotor output shaft to be circulated by rotation of the rotor output shaft. The secondary output shaft is engaged by the endless traction member to be rotated by circulation of the endless traction member. The secondary output shaft extends from inside the casing to outside the casing to be operatively connected to the reel to rotate the reel.
