Abstract: A pedal crank drive comprises two independently freely rotatably mounted pedal cranks 1', 1" which as they move downward from the top dead centre position are engageable over a predetermined turning angle range with arms 5', 5" which are nonrotatably connected to the chainring spindle. It is proposed that the chainring shaft 3 has nonrotatably mounted on it the chainring 7 and arms 5 with projections 6 and that the axis 15 of the chainring shaft is parallel to and spaced apart from the axle 16 of two coaxial hollow cylinders 2', 2" on which the pedal cranks are independently freely rotatably mounted. As a result the catch plates 4 of the pedal cranks - each pedal crank being equipped with such a catch plate - each engage with the protections 6 on the arms over a certain turning angle range. <IMAGE>

Abstract: Hardmetal lamina (15) are cut, by a process known as electrical discharge machining, from a block of hardmetal (10) using a wire electrode (12). The laminae so formed may then be attached by adhesive or epoxy resin to a suitable base (16) in order to form a hard metal surfaced tool. Provision is made for preventing this hardmetal from shearing from its mounting, and also to remove any heat generated within the hardmetal. Reference is made especially to using the above construction for a 'slipper' within a tile producing machine. The word 'hardmetal' is used to denote powdered carbides of the transition metals, cemented into solid masses by a matrix of a metal of a lower melting point.

Abstract: A method and apparatus (10) for selectively sintering a layer of powder to produce a part comprising a plurality of sintered layers. The apparatus includes a computer (40) controlling a laser (12) to direct the laser energy onto the powder to produce a sintered mass. The computer either determines or is programmed with the boundaries of the desired cross-sectional regions of the part. For each cross-section, the aim of the laser beam is scanned over a layer of powder and the beam is switched on to sinter only the powder within the boundaries of the cross-section. Powder is applied and successive layers sintered until a completed part is formed. The powder may consist of a plastic, metal, ceramic, or polymer substance. In the preferred embodiment, the aim of the laser is directed in a continuous raster scan and the laser turned on when the beam is aimed within the boundaries of the particular cross-section being formed. Preferably, the powder dispensing mechanism includes a drum which is moved horizontally across the target area and counter-rotated to smooth and distribute the powder in an even layer across the target area. A downdraft system provides controlled temperature air flow through the target area to moderate powder temperature during sintering. <IMAGE>
