This fan-blade wheel is driven by a drive shaft that passes through the cone and out in the area between the pipes. The drive shaft is driven directly by a motor or through a belt or gear-train drive system.

Abstract: The invention relates to a cooling device having an evaporator, a blower with an outlet connecting piece, a condenser, and a compressor. A condensate collecting pan is positioned below the evaporator. The collected condensate water flows from the condensate collecting pan through a discharge pipe. In order for relatively large quantities of accumulating condensate water to be removed from the cooling device, the condensate water flows from the discharge pipe into a condensate collecting pan positioned below and downstream of an outlet connecting piece of the blower which discharges a warm air current. The warm air current of the blower flows to an outlet hole through an air channel which is connected to an outlet connecting piece of the blower.

Abstract: An arrow rest for an archery bow which is quickly and easily replaceable and laterally adjustable in the field without any need for tools. The arrow rest has an arrow support arm which pivots upon movement of the arrow shaft and fletching across it and by a resilient arm hinge automatically returns to an initial predetermined position after discharge of the arrow. The arrow rest mounts on the end of an adjusting screw which extends through a hole in the handle portion of a bow. This invention provides easy lateral adjustment and complete replacement of the arrow rest in the field, without any need for tools, while maintaining the precise position and alignment of the arrow rest. This invention also provides an arrow rest that creates very little noise when an arrow shaft and fletching move across the arrow support arm.

Abstract: This invention relates to an air turbulence massage device having a control device with a blower unit and a turbulence matting which can be placed in a bathtub. The turbulence matting can be connected with the blower unit outlet by means of an air tube. The turbulence intensity, using a preset program, can be adjusted and changed between a lower and an upper value by varying the rotational speed of the blower unit. To achieve siultaneous switching times with the turbulence process, this invention provides that the lower value is preset as a minimum pressure value which is enough to overcome a counter-pressure predetermined by a normal water level in the bathtub. The upper value is preferably preset as an adjustable maximum pressure value.

Abstract: This invention relates to a control device for an air turbulence massage device having a housing. The housing accommodates a blower unit which can be driven by an electrical motor. The housing has a connecting piece for an air tube that is in communication with a turbulence matting. The housing accommodates a check valve device which, when the control device is shut off, prevents water from flowing back from the turbulence matting to the electrical motor and the blower unit. The housing comprises an external housing and a separate internal housing. Air flow is separated from a water discharge path leading from the internal housing such that the blower unit and the electrical motor never contact the water flowing into the housing and the water can flow out of the control device.

On both sides of the film hinge, tension bands are positioned, which, in the closed position, are tensed. The tension bands are held, with their ends, in recesses (11) in the casing walls, and have, over their entire length, an approximately uniform cross section. The outermost surfaces of the tension bands align with the casing external surfaces.

Abstract: A device for determining the temperature of a glass ceramic plate heated using heat coils or halogen lamps with a temperature sensor which emits a signal for a control circuit corresponding to the temperature of the glass ceramic plate. The heat coils or the halogen lamps are positioned in the internal space of a cylindrical vessel-like insulation support, and in which the surrounding wall of the insulation body, under spring tension, abuts on the glass ceramic plate heated by the radiation of the heating coils or the halogen lamps. Adequate control precision can be achieved by having the temperature sensor positioned in a recess in the surrounding wall of the insulation body, and is in a thermally-conductive connection with the lower side of the glass ceramic plate. The recess for the temperature sensor is positioned at a distance to the internal space of the insulation support and thus the dynamics of the control behavior can be adjusted to low hysteresis and optimized.

Abstract: A trapped-vortex pair flowmeter having a body with an inlet and an outlet. The inlet has a nozzle which forms a fluid jet having two primary counter-rotating vortices. The body has a chamber between the inlet and outlet through which the fluid jet flows. Two wedges are secured within the chamber. Each wedge has an inner side and an outer side. The inner sides of both wedges form a converging channel between the upper portions of both wedges. Both wedges have a gap between the inner sides of the wedges through which the converging channel passes. The inlet nozzle directs the fluid jet into the converging channel. A small portion of the fluid jet flows through the gap within the converging channel, but the majority of the fluid jet flows back over the top sections and down the outer sides of the wedges. Pressure sensors located within the chamber detect alternating high and low pressures at various points within the chamber.
