Abstract: ABSTRACT       The present invention provides a process for carrying out analytical determinations by mixing and incubating a sample solution with at least one reagent solution and optical measurement of one parameter in the incubated reaction solution mixture, mixing, incubating and measuring being carried out during the action of a centrifugal force, wherein, under the influence of the centrifugal force, the sample solution is brought together with a soluble dry reagent, with at least partial dissolving thereof, and the mixture or the solution is forced centrifugally through a plurality of small hollow spaces, the centrifugal force and the flow resistance of the small hollow spaces being so adapted with regard to one another that a complete dissolving and mixing of the reaction components and possibly incubation takes place before the reaction solution passes from the small hollow spaces into a measuring chamber in which the measure-ment is carried out.     The present invention also provides an insert element for a centrifugal analysis rotor, wherein it comprises at least one analysis reagent in dry form and has a plurality of very small interconnecting hollow spaces which connect a sample providing chamber with a measuring chamber.

Abstract: ADDITION OF WATER TO REGENERATION AIR                        Abstract A process for economically converting carbo-metallic oils to lighter products.  The carbo-metallic oils contain 650°F and material which is characterized by a carbon resi-due on pyrolysis of at least about 1 and a Nickel Equiva-lents of heavy metals content of at least about 4 parts per million.  This process comprises flowing the carbo-metallic oil together with particulate cracking catalyst through a progressive flow type reactor having an elongated reaction chamber, which is at least in part vertical or inclined, for a predetermined vapor riser residence time in the range of about 0.5 to about 10 seconds, at a temperature of about 900 to about 1400°F, and under a pressure of about 10 to about 50 pounds per square inch absolute sufficient for causing a conversion per pass in the range of about 50% to about 90% while producing coke in amounts in the range of about 6 to about 14% by weight based on fresh feed, and lay-ing down coke on the catalyst in amounts in the range of about 0.3 to about 3% by weight.  The spent, coke-laden cata-lyst from the stream of hydrocarbons formed by vaporized feed and resultant cracking products is separated and regenerated in one or more regeneration beds in one or more regeneration zones by burning the coke on the spent catalyst with oxygen.   The bed density is in the range of about 25 to about 50 pounds per cubic foot and the bed or beds are sustained by fluidization gas containing combustion-supporting gas having a linear velocity in the range of about 0.2 to about 4 feet per second.  Liquid water is added to the bed or beds in a weight ratio of water to converter feed from about 0.01 to about 0.5 to at least partly absorb the heat produced by the burning coke.  The catalyst particles are retained in the regeneration zone or zones in contact with the combus-tion-supporting gas for an average total residence time in said zone of zones of about 5 to about 30 minutes to reduce the level of carbon on the catalyst to about 0.25% by weight or less. The regenerated catalyst is recycled to the reac-tor and contacted with fresh carbo-metallic oil.

Abstract: ABSTRACT OF THE DISCLOSURE      A portable power tool includes a manually actuable safety lever and an inertial safety system for activating a brake of the tool to provide a more effective safety ar-rangement.  A first spring applies the brake when the safety lever contacts the hand, wrist or arm of an operator during "kick-back" or like violent movement of the tool.  A second spring is operable independently of the safety lever for also releasing the first spring.  An inertia mass is dis-placeable effectively independently of the safety lever when the brake is in the inoperative condition.  This inertia mass releases the second spring, so releasing the first spring and applying the brake, upon occurrence of "kick-back" or the like.  Preferably, the second spring operates a hammer release mechanism for striking a locking lever re-leasably retaining the safety lever.  A band brake of a chain saw or circular saw may particularly be operated in this manner.

Abstract: ABSTRACT OF THE DISCLOSURE     Process for the preparation of fiber-reinforced flat bodies containing a hardenable binder A process for the preparation of fiber-reinforced flat bodies containing a hardenable binder is described, wherein a core layer containing the prepared, unhardened (liquid) binder is placed between a cover layer and a backing layer; in order to provide this three layer body with its own internal cohesion even in the unhardened condition and to improve the mechanical properties of the body in the hardened state, the three layers, at least one of the outer ones of which consists of fibers capable of active fiber bonding, are needle bonded together prior to the hardening of the binder, so that the layers will hold together in the deformable state, whereupon the binder is hardened, while the fibers provide the body with an elasticity different from that of the hardened core layer. Prior to hardening, the composite body may be provided with orifices or slits, without the loss of the mass of the core layer from the body. The mass of the core layer is held by holding fibers, introduced during the needle bonding process and connecting the cover layer with the backing layer through  the core layer.

Abstract: HIGH SPEED DATA BUS STRUCTURE            AND SYSTEM          ABSTRACT OF THE INVENTION           A very high speed data bus system for communication among the various functional units that may constitute a large computer system.  The functional units are mounted in immediately adjacent connectors on the backplane to define a populated section of effective characteristic impedance Z0' and one or two unpopulated sections of impedance Z0.  A popu-lated end of the transmission line is resistively terminated with a resistance corresponding to Z0' while the unpopulated end is terminated with a resistance corresponding to Z0.  The border between the populated and unpopulated sections is terminated with a resistance corresponding to 1/(1/Z0'-1/Z0), thus eliminating signal reflections.  Driver gating circuitry responsive to first and second data input signals, an enable signal, and a conditional inversion input signal performs multiple levels of gating with a minimum of propagation delay.  The preferred differential receiver amplifies a rela-tively low level differential input signal and performs an exclusive OR function with a conditional inversion signal with a minimum propagation delay between the signal input and an output line pair.  Each functional unit has an associated port which operates to accept all related information that makes up a communication, or if this cannot be done, to accept none of the information.  To implement the indivisi-bility of transfers, the control logic for each port includes screening circuitry responsive to the state of the port's input buffers, and further responsive to flags from the functional unit for selectively accepting or rejecting bus information, and further includes screening constraint cir-cuitry to ensure that the port accepts all or none of the information that makes up the transfer.  Depending on the flag, the rejection may be total, or may apply only to a designated class of transfers.

The gauging system employs quadrature phase discrimination to provide signals indicative of the position and direction of movement of that portion of the movable reflecting member within the analytical radiation path.  In a preferred embodiment, the quadrature phase discrimination system has an optical path that is generally coaxial with at least that portion of the analytical radiation path at the movable reflecting member.         Multiple quadrature phase discrimination systems may be employed to provide an indication of the position and direction of movement of three portions of a flat movable reflecting member, one of which portions may be within the analytical radiation path at the reflecting surface of the reflecting member.  The gauging system may further provide an initial reference indicative of the position of the movable reflecting member independently of the beam splitter and may include an additional quadrature phase discrimination system.  The reference system may be employed redundantly to provide an indication of position and direction of movement of the movable reflecting member.
