Abstract: ABSTRACT OF THE DISCLOSURE     There is provided a new method for analysis of the size and/or distribution of particles emanating from a mother liquid by sedi-mentation in a rotating disc centrifuge, particularly a photosedi-mentometer.  The method is characterized in that the spin fluid or medium is  formed externally of  the  disc as distinct  from being formed  within  the  disc  while  it  is  rotating.   The  externally prepared spin medium is formed from at least two miscible liquids of different densities for example, methanol and water,  in a manner such  that  they  are  substantially  incompletely  mixed  whereby  a density gradient is established in the spin medium.  Thereafter the spin medium is injected into the disc while spinning at a given speed, and later the mother liquid is injected.  Results are closely comparable  to  the buffered  line  start method  described  in  U.S.          Patent 3,475,968.

Abstract: CIRCULAR SEISMIC ACQUISITION SYSTEM            Abstract of the Disclosure A marine seismic survey is disclosed in which a plurality of steerage centers are selected for circular traversal thereabout by a marine vessel towing a streamer cable.  While the vessel and the streamer are following a circular track about a steerage center, the feathering of the cable creates a separate concentric track line for each of the mid-points between the receivers included in the cable and the source.  In this manner an areal cover-age is assured which requires no reliance on unpredictable and uncontrollable currents for the desired feathering. An additional important feature of the current disclosure is that there is little wasted time in which the survey vessel moves outside of the overall surveyed area.  A preferred course tracking for the vessel is to move from the arc of one steerage course line to another in tangential fashion.

Abstract: Roller Suspension Apparatus for a Belted Vehicle Abstract of the Disclosure Roller suspension apparatus are useful for example in belted vehicles.  The heretofore known roller suspension apparatus impart a shear force to the spring due to the geometry and the relationship between the roller mounting arms, the walking beam, and the pivot pins to which the arms and beam are pivoted.  The subject roller suspension apparatus has a pair of arms and a force transmitting beam pivotally connected to a single pivot shaft.  The mounting surfaces to which a pair of springs are attached are then arranged relative to the pivot shaft such that substantially only compressive forces are imparted to the springs.  Thus, the full shock absorbing potential of the springs is fully utilized.

Abstract: Abstract of the Disclosure:  To control the inter-mittent movement of a conveyor belt or carousel, fitted with molds, in a unit for the manufacture of moldings from multi-component plastics, an intended/actual value comparison of the speed of the conveyor belt or carousel as a function of the distance of the molds from fixed devices for filling, demolding and similar operations of the molds is carried out so as to provide control signals for the electric motor.  The actual value is det-ermined from a signal voltage generated in correspond-ence with the rotary movement of the electric motor.  The signal voltage is additionally, and in parallel to the speed regulation, converted to electric pulses which are summed in their time sequence, as a function of the move-ment steps of the conveyor belt or carousel, and are compared with a predetermined master function which can be varied.

Abstract: ABSTRACT A VLSI chemical reactor includes a fluid flow guide spaced from the corresponding substrate in the form of a wafer for significantly reducing contami-nation in the processing of semiconductor wafers. Processing chemicals are introduced in a continuous process through a central tube and through the fluid flow guide which is substantially planar and which is parallel to the surface of the wafer. A predetermined gap is maintained between the guide and the wafer such that fluid is maintained in the gap at all times critical in the processing of the wafer. In one embodiment, the guide is optically transparent at predetermined portions to permit monitoring of the chemical reaction taking place on the surface of the wafer to permit control of fluid flow to the wafer. Because of the uniform gap, the fluid guide insures a constant thickness and composition of the optical path, and thus more accurate measurements. All drying steps are done directly and include the steps of replacing the working fluid with an inert gas and increasing the speed of rotation of either the wafer or the guide to remove any liquid or particulate matter by centrifugal force. Bubble reduction and fluid mixing apparatus, including different fluid guide configurations, gas relief orifices and offset rotational axes, are also described. Moreover, in one embodiment orthogo-nal and orbital vibrating arrangements are used in lieu of rotating motion.
