Abstract: The windmill or fan of very light construction has a streamlined hub (27) attached to a rim (1) by pairs of spokes (2,3). The rim is made of plastic or from a light metal tube. The spokes are attached to the rim by a fixing plate which permits limited angular movement. The other ends of the spokes are attached to plates (4,5) inside the hub housing (27). These plates can be forced apart by a turnbuckle (7) in order to exert the necessary tension on the spokes. The spokes form supports for the blades which are built up from sections of plastic foam or light metal. Guide rollers (23,24) are fitted in the outer housing (21) and support the rim in both directions against the axial force exerted by the wind.

Abstract: A laser enhanced electroplating system or etching system or conventional electroplating or etching system includes a continuous electrochemical processing system with a sheet of material to be treated electrochemically passed from a supply roller to a plating bath and out over an exit roller with the plating system under automatic control. A rinse-tank is also proved in series with the plating tank. The sheet to be treated electrochemically is coated in tank (21) with a protective film which prevents electrochemical action from occuring where it is present, but which sheet can be removed in a predetermined location. The protective film is removed where desired to provide a mask by means of a laser (27) which is scanned under automatic control. Then the plating or etching operation occurs through the openings in the mask. A rinse-tank contains a solvent capable of removing the mask from the sheet subsequent to the plating or etching operation. An array of lasers can be employed. An array of lasers can be multiplexed, synchronously activated or pulsed. The electrochemical operation can be performed with the concomitant application of energy from the laser in order to enhance the chemical action in areas from which the masking (protective) film has been removed. The laser can be scanned by means of a mirror, which oscillates or can be fixed. The masking material is composed of an organic material such as glycol phthalate, paraffin, photoresist, gelatin, etc.

Abstract: System and apparatus for the controlled intermixing of hydrogen/oxygen gasses with non-combustible gasses to reduce the burning temperature and velocity of the hydrogen gas in a burner. The system utilizes a non-electrolysis hydrogen generatorfor developing the hydrogen/oxygen gasses. The hydrogen gas with non-volatile gasses are intermixed in a controlled air intake chamber. The exhaust gasses of the burner are returned as the non-volatile gasses to the mixing chamber in a closed loop arrangement. Upon attaining the proper burning temperature and velocity of the hydrogen gas the ratio of hydrogen/oxygen and non-volatile gasses is maintained. To effect a practical utilization, the generation of the hydrogen/oxygen gasses are controlled in start-up and in quantity. The control of the generation of gasses is effected by one or more variable parameters; such as varying the voltage applied to the plates. varying the pulse rate of the voltage on the plates, varying the spacing between the plates, switching the number of plates, and plate configuration. The hydrogen/ oxygen generation is on demand; that is the hydrogen/ oxygen generation on start-up is only on demand and thereafter generation is controlled in quantity by the need much in the same manner as an accelerator.

Abstract: Phase-locked loops for signal frequencies of approximately 100 MHz using a ring modulator are known. Difficulties can arise when an active loop filter is used with an operational amplifier if a positive and a negative operating voltage are not available. According to the invention, a phase-locked loop containing a ring modulator with push-pull output is proposed, in which the two push-pull outputs are connected via a symmetrical filter and a symmetrical arrangement for reference potential superimposition to a symmetrical loop filter, and via the latter to an amplifier with push-pull control. Phase-locked loops according to the invention are employed in particular for generating the clock pulse for digital signal regenerators. <IMAGE>

Abstract: Molecular sieve carbons of tailored pore aperture size are prepared by sorbing a hydrocarbon, preferably propylene, in a degassed micropore-containing carbon substrate at an intermediate temperature, removing the physically held hydrocarbon while retaining at the pore apertures irreversibly fixed (chemisorbed or polymerized) hydrocarbon, and cracking the retained hydrocarbon at significantly higher temperature to deposit pyrocarbon at the pore apertures. To protect these molecular sieve carbons and other gas-sorbing carbons from loss of capacity and/or selectivity by exposure to moisture and/or oxygen, these carbons are treated with hydrogen at superatmospheric pressure.
