Abstract: To provide a conveyor system for divergence and convergence, which is capable of always satisfactorily diverging or converging articles without regard to their size. When the roller axes 19 are orthogonal to the transport path 9, an article 60 to be transported is transported downstream by the rollers 16 without being sorted. When it is desired to sort the article 60, an angle changing device 30 is actuated to individually change the angles of inclination of the rollers 16, such that those rollers which are disposed in the upstream region are given a smaller angle of inclination, the angle of inclination being gradually increased. Diversion of the article can be effected such that it has its direction of orientation gradually changed from a smaller angle to a larger angle while it is gradually moved to one side by a smaller amount to a larger amount.

Abstract: Structure for and method of cooling or heating a space which is exposed to a natural heat influence. The structure includes a first fluid store buried in the ground so as to be at the temperature of the surrounding earth, a heat exchanger positioned in a space to be cooled and means for passing a fluid between the first fluid store and heat exchanger in a closed circuit. The structure of the invention may also include heat units for the space and hot water heaters connected in the closed circuit between the heat exchanger and first fluid store and a heat pump connected between the heat units and water heaters and the closed circuit. In a further embodiment of the invention, a second fluid store is provided in conjunction with the heat exchange structure which may also be buried so that waste heat may be utilized to heat the fluid in the second fluid store.

Abstract: A compound bow with primary and secondary pulleys at the distal ends of the flexible limbs designed to reduce the draw force at the end of the draw. Pulley shape is designed to alter the force-draw curve to provide a flat plateau at the maximum draw which drops off again to the holding draw force. Draw length is controlled by curvature contour at segments of the secondary cable pulleys to achieve short, medium or long draw lengths with selective pulley segments which can be attached to a base primary pulley. A draw string pulley has a first perimetric section which is circular and a second connecting curved perimetric section which has a progressively decreasing radii from each end to the center with radii less than that of the first section. In some embodiments, three or four zones are provided. These zones can be created with add-on plates secured to a basic pulley.
