Abstract: A propeller according to the invention has a hub centered on and rotatable about a hub axis and formed with a bore extending along the axis and with a plurality of identical, radially outwardly open, and angularly equispaced sockets centered on socket axes extending at least generally radially of the hub axis. Respective identical blades each have a base complementary to and snugly fittable in the respective socket and an outer part extending radially outward from the hub along the respective socket axis when the respective base is fitted therein. Respective locks are provided in the hub for releasably fixing the bases in the respective sockets against relative movement between the respective blades and the hub. The sockets and bases are normally complementarily cylindrical and both centered when the bases are in the sockets on the respective socket axes. Thus the blades can turn about the respective socket axes on the hub when released by the respective locking means. In addition each socket is formed with an annular groove open inwardly radially of the respective socket axis and each base is formed with a similar annular but outwardly open groove confronting the respective inwardly open groove when the base is fitted in the respective socket and forming with the respective inwardly open groove an annular chamber. The system for locking includes a respective plurality of balls generally filling the chamber and something that can press the balls tightly against the respective grooves.

Abstract: The invention relates to preventing oil damage in open water. The invention is based on the fact that the viscosity of oil changes as a function of temperature. Fig. 1 shows the operating principle. The catamaran-type vessel is provided with two cylinders (2) which are kept at a lower temperature than the water, using cooling units (5). The oil (7) floating in the water comes into contact with the cylinder (2), congeals and adheres to the surface of the cylinder. As the cylinder rotates, the oil is transported on the surface of the cylinder until it reaches a heated collection gutter (8) where it is collected. From the gutter it is directed into a collecting tank which is located in the vessel. The dimensions of the vessels, of the cylinders, and of the cooling unit can be chosen freely according to the conditions.

Abstract: Processing and apparatus are provided for upgrading the octane of a mixed hydrocarbon gasoline feedstock by an integrated adsorption-isomerization process which catalytically isomerizes normal paraffinic hydrocarbons and concentrates non-normals in a product stream, in both the reactor-lead and absorber-lead configuration. The process includes passing an absorber feed stream comprising hydrogen as well as hydrocarbons to an absorbent bed to absorb normal hydrocarbons. The hydrogen is preferably obtained from a hot hydrogen-containing process stream which is not cooled or separated into component parts prior to forming the absorber feed. In some embodiments, the hot-hydrogen containing stream comes from reactor effluent and in others from desorption effluent. According to the invention, the only hydrogen which will require cooling and separation from a hydrocarbon component is that which is recycled for desorption. The invention provides improved energy efficiency and can reduce equipment size and complexity.

Abstract: A method for preparing graft polymer dispersions having broad particle size distribution without wildly fluctuating viscosities is disclosed. The method comprises:   (a) preparing intermediate graft polyol dispersions containing 30 percent by weight or less solids to achieve a broad distribution of partial sizes in a continuous process by feeding a sufficient amount of an ethylenically unsaturated monomer and a free radical initiator into a flow reactor at a temperature sufficient to promote polymerization, and (b) charging the intermediate graft polymer dispersion of (a) to a semi-batch reactor as seeds for further grafting to increase the solids content of the dispersion to above 30 percent by weight by feeding an effective amount of an ethylenically unsaturated monomer and a free radical initiator into the semi-batch reactor at a temperature sufficient to promote the growth of the seeds, whereby the seed particles generally grow larger but retain the characteristic of broad size distribution. The graft polymer so formed is useful in the production of polyurethanes. n

Abstract: A number of devices are known in the prior art for determining the number of drops passing through a drip chamber. However, one disadvantage of these devices which has been noted is that the desired drop rate cannot always be maintained and must be corrected manually by the operating personnel. The device according to the invention provides a remedy to this problem, by means of a control mechanism with a housing (3), which has in a vertical direction a bore (13) with a widened recess (7), into which, in the use state, the roller clamp housing (4) with roller clamp wheel (5) is introduced, while the tube (6) is held by the bore, and the roller clamp wheel (5) being held, at its part projecting out of the housing slot (16), approximately positively by a guide segment (11) which can be moved up and down vertically in the housing (3) and which is connected to a drive (10), and the control mechanism having a keyboard (14) for setting the drop rate or intended drop number/time unit and an electrical cable (15) with which it is connected to the drop counter (2), and the intended drop number/time unit being stored in a microprocessor which is contained in the control mechanism (3) and which, in the event of a deviation with respect to the actual drop number shown on the display (12), activates the drive, which leads to a vertical upward or downward movement and, consequently, to a reduction or increase in the drop rate or the liquid quantity to be applied/time unit, and to the compensation of desired and actual values of the drop number. <IMAGE>

Abstract: A broadband measuring system for network analysis exhibits a sweep generator (1) and a network analyser (3) which exhibits a reference signal input (4) and measurement channel inputs (5, 6). A circuit arrangement (7) is connected with coaxial connecting elements between the output (2) of the sweep generator (1) and the network analyser (3) and exhibits a distributor circuit, the input (9) of which is connected to the output (2) of the sweep generator (1) and which is connected via output connections to the network analyser (3). The circuit arrangement (7) furthermore contains a measuring bridge with directional characteristics, the inputs and outputs (21, 22, 23) of which are decoupled in different manners. To improve such a measuring system in such a manner that the quality of the reference branch becomes independent of the matching of the object to be measured, the distributor circuit is formed by a further measuring bridge (30) with directional characteristics, the high degree of decoupling (24) of which is located between the two output connections (10, 12). The advantageous result of this is that the return loss of the wave reflected from the object to be measured when the matching is not optimum is improved by at least two orders of magnitude in the reference branch. <IMAGE>
