Abstract: ABSTRACT OF THE DISCLOSURE           Apparatus for lifting oil off the surface of water comprises a vessel which is capable of sweeping back and forth through the floating oil.  The vessel is equipped with oil catching and storing equipment and also with an oil lifting mechanism having a plurality of pickup discs arranged in sets each rotatable about a horizontal axis extending transversely of the mechanism.  This lifting mechanism is operated to move each set of pickup discs in turn between a loading position at least partly immersed in the water and a discharge position adjacent the oil catching and storing equipment.  A drive for each set of pickup discs rotates the discs during operation of the mechanism at a first speed in the loading position to coat the discs with oil and at a second speed in the discharge position so that at least a portion of the oil adhering to the discs is thrown off by centrifugal force into the oil catching and storing equip-ment.

Abstract: ABSTRACT A method of providing access to a multiplexed data bus having a plurality of data processing units coupled thereto.  Each unit self-assigns sequence numbers thereto for identification purposes.  The unit having the lowest sequence number obtains immediate access to the bus and may relinquish the bus by transmitting a control word, or token, with an incremented sequence number.  All units receive the token but only the unit having the incremented sequence number gains access to the bus.  The token passing continues through the series of sequence numbers and then recycles when no unit accepts the token (bus timeout).  A newly added unit self-assigns a sequence number equal to the one transmitted prior to the bus timeout and thus acquires bus access on the next cycle.  If a unit in the cycle fails, a bus timeout occurs mid-cycle and the access loop recycles.  The units not gaining access to the bus during the cycle decrement their sequence numbers to close the gap, and hence gain access on the next cycle.  The method allows for continuous system operation if units are added or deleted, without interrupting bus operation.

Abstract: ABSTRACT            The invention relates to a method of achieving a con-tainer of polyethylene terephthalate or similar thermo-plastic material from a tubular blank of chiefly amor-phous material. A mechanical forming element moves a transitional zone between amorphous (thicker) material and thinner material stretched to flow during simulta-neous elongation of the blank in the direction of movement of the transitional zone. According to the invention the stretched and oriented material is heated to a temperature higher than the temperature of the ma-terial immediately before stretching. As a result, the internal stresses produced in the material during earlier stretching are relieved.  Heating causes the length of the material in the direction of stretching also to be  reduced. Each subsequent forming stage for shaping the container takes place at a temperature lower than the temperature at the immediately preceding forming stage.

Abstract: "ABSTRACT":            "Semiconductor device and method of manufacturing such a semiconductor device".     With the aid of anisotropic etching techniques. such as plasma etching and reactive ion etching, inter-connection patterns can be obtained having accurately de-fined rims. According to the invention, these rims are provided inter alia at the area of contacts to be formed.          The contacting zone thus formed, which has an accurately defined form, can be manufactured with rims of, for example, a refractory metal or polycrystalline silicon. In the latter case, a semiconductor zone (emitter zone, base contact zone, source, drain etc.) can be formed through the poly-crystalline silicon in the subjacent semiconductor body.          In this manner, very small structures can be obtained, whilst moreover different kinds of transistors can be manu-factured in the same semiconductor body.

Abstract: ABSTRACT The invention is a technique for injection-molding an insulating liner onto the surface of a metal spool to be included in an electromagnetic flowmeter in which the fluid to be metered is conducted through the lined spool.  The spool is composed of a cylindrical body having end flanges and a pair of diametrically-opposed circular bosses disposed midway between the flanges to receive the meter electrodes.  To carry out injection-molding, the spool is supported within a mold which defines a liner cavity conforming to the inner surface of the cylindrical body and to the faces of the end flanges, the liner cavity communicating with cavities conforming to the inner surface of the electrode bosses.  The molding material is injected into a sprue in the mold which runs along the longitudinal axis of the spool toward the hub of a runner extending radially toward an axisymmetric ring gate opening into the liner cavity at a point adjacent the boss cavities. The molding material passing through the ring gate then flows in opposite directions in the linear cavity to evenly fill this cavity as well as the boss cavities without creating weld lines therein.  Among the advantages arising from use of this technique is the avoidance of weld lines that weaken the liner structure.
