Abstract: A magnetic self-latching device for a gate has a main body with handles on either side for operation or has an arrangement to be remotely actuated, for example electrically. A latching body has a high strength magnet usually provided at the bottom of a cavity which defines a latching shoulder. The latching body is adapted to be fixed to a gate post. The main body, with its housing, can be mounted on the gate frame and incorporates a latch pin which, in the door-closed position, is displaced by magnetic attraction to an extended latching position and against the biasing of a return spring. The gate cannot be opened until actuation of the mechanism occurs, for example by rotating a handle to retract the pin against the magnetic force; the gate can then be swung open. When the handle is released, the biasing spring retains the latch pin in a retracted position.

Abstract: The present invention provides a wheel-immobilizing device that does not require holes or indentations in the wheel in order for the device to be secured around the wheel or caster being immobilized. Additionally, a wheel-immobilizing device according to the invention is configured such that it may be placed on the ground in front of a cabinet, and the cabinet simply rolled into position with one of its casters between side walls of the device. The wheel-immobilizing device is then secured around the caster by passing a cross member or, in some embodiments, two cross members through the side walls on either side of the caster stem and then securing the cross member or members in position, thereby locking the wheel-immobilizing device to the caster of the cabinet and hampering rolling movement of the cabinet.

Abstract: A latching device (1) particularly for installation such as swimming pool gates may have an automatic magnetic latch with a child resistant device to control access. The child resistant device may include an operating handle (10) at an elevated location to be out of the reach of the child and an alternative operating device (11) is provided at a lower location with child resistance provided typically by a push button arrangement (12) acting through a cam and cam follower to raise a latching arm (3) against the biasing to the latching position. A simple pronged key (16) for a pushing action can be provided, but another aspect consists in a mechanically actuatable key pad (20) which can readily be operated by an adult even in a wheelchair, but which is resistant to child actuation. For example, a selected two of eight buttons may be required to be depressed to permit the key to actuate the push button.

Abstract: The present invention provides a blade driving mechanism for a table saw, wherein the table saw comprises a main frame and a saw blade mounted to and driven by the blade driving mechanism, and the blade driving mechanism comprises an electrical motor mounted to the main frame, with the motor being capable of sliding with respect to the main frame; a belt driving system for transferring the rotation of an output shaft of the motor to the saw blade; a center-distance setting means connected between the motor and the saw blade, for adjustably setting the center-to-center distance between the motor and the saw blade; and a saw-blade height adjusting device being operable to adjust the height of the of the saw blade.

Abstract: A process for the preparation of inhibitors of HMG-CoA reductase, such as simvastatin, from 4-silyloxytetrahydropyran-2-ones with triethylamine trihydrofluoride being used as the desilylation reagent is described. The reaction is performed in organic solvents, a mixture thereof or without solvents. It is characteristic of this reaction that no additional impurities are obtained and that it takes place without the use of additional catalysts and with low excesses of the reagent.

Abstract: The invention relates an electric sharpener, comprises a main frame, a main shaft, a motor, a transmission wheel, a grinding stone, and an electric control circuit. The motor is mounted on an angular frame which in turn is mounted on the main frame. The transmission wheel is fixed to an end of the main shaft, and the output shaft of the motor is tightly pressed against the periphery of the transmission wheel so as to drive it. A tool rest is fixed onto the main frame in a vertical or horizontal mounting orientation. A water vessel is fixed to the main frame, and the lower portion of the grinding stone dips into the water contained in the water vessel. Special clamps and attachments for grinding different tools are provided. The electric sharpener can be used for grinding various woodworking or household tools.
