Abstract: CENTRIFUGAL SCREENING APPARATUS              Abstract of the Disclosure A centrifugal screening apparatus for scalping or sizing bulk materials in which an auger assembly conveys the bulk materials from an intake chamber into a cylindrical screening sleeve mounted within an enclosed screening chamber and subjects the bulk materials to centrifugal force for impingment against the screening sleeve, with the fines passing through the screen for gravity discharge from the screening chamber and the tailings being conveyed to a separate tailings chamber for separate gravity discharge therefrom.  The auger assembly within the screening sleeve is equipped with a cylindrical shell integral with the auger assembly and extending the ef-fective length of the screening sleeve that defines along the length of same uniformly spaced apertures thereabout that are separated by imperforate walling.  The shell apertures are proportioned to restrict bulk materials movement therefrom under the centrifugal forces involved so that the bulk material feeding action of the auger assembly longitudinally of the screening sleeve acts to distribute the bulk material lengthwise of the shell for uniform screening application of the bulk materials to the screening sleeve.  Tramp metal and other foreign materials are retained within the shell for removal when the apparatus is not operating, thereby protecting the screening sleeve against rupture during operation.

Abstract: ABSTRACT OF THE DISCLOSURE           A rotary fluid coupling for use with such devices as tracking concentrating solar collectors is disclosed which is capable of providing excellent sealing characteris-tics over a wide temperature range at relatively low inter-nal fluid pressures.  The coupling includes a stationary body member which defines an internal fluid passage operating in conjunction with a conduit member one end of which is received the stationary body member forming a con-tinuous passage therethrough wherein the conduit member is rotatable within the stationary body.  A dual sealing system is employed in which a pair of resilient radial seals are utilized spaced axially along the interface between the sta-tionary member and the conduit member.  Any leakage past the first seal is collected through a drain opening in the sta-tionary member between the two radial seals.  A container may be attached to the drain opening to indicate and collect any leakage at the rotary joint.  In this manner the second seal, then, becomes a pressure seal and the leakage container prevents any possible damage being done by the leakage of corrosive fluids from the system and serves to indicate required maintenance.  The rotary joint solves the problem of preventing leakage over a wide temperature range in a low-cost, simple manner.

Abstract: ABSTRACT   In the processing of garbage there is the technical problem of on the one hand exploiting to the fullest the energy content of the garbage whilst on the other hand disposing of the garbage with a minimum of pollution.     In contrast to the usual methods using extensive degasification or gasifica-tion or obtaining oil at low or medium temperature pyrolysis or by obtaining active carbon together with substantial degasification by using medium and high temperature pyrolysis, with low temperature pyrolysis of between approxi-mately 240° and 380°C there is produced 2 garbage containing sufficiently high carbon enrichment and conservation of carbon compound 5 in order to obtain a storable fuel suitable for domestic as well as industrial ovens.  This is achieved by directly heating and passing an inert heating gas through the garbage in a continuous reactor (1) provided with temperature control circuit (2,27,28).  The heating and flushing gas can preferably be obtained by burning the pyrolysis waste gases at (5) discharged by the reactor (1) in a burner (6) and a heat exchanger (13) for useful heating connected in series with the burner.(6).

Process for the concentration of fibrous material in a mixture thereof with non-fibrous material, by subjecting an aqueous suspension of the mixture to centrifugal force in a hydrocylone to obtain an overflow enriched in fibre and an underflow of reduced fibre content, the aqueous suspension which is admitted to the hydrocylone being the fibre-enriched fraction which results from a preliminary classification in which an aqueous suspension of lower fibre: non-fibre ratio is submitted to flow under conditions which bring about settling out under ordinary gravitational force of material reduced in fibre content and formation of a fibre-enriched fraction above it.            In the process, the underflow flow from the hydrocylone is incorporated in the aqueous suspension which is submitted to the preliminary classification.            The process, which keeps to a minimum the amount of valuable fibre lost, is specially applicable to the concentration of fibres in the fibrous products (mineral wool) formed by disintegrating silicate and like mineral melts, which commonly contain relatively high proportion of granular material ('shot').

Abstract: MICROCONTROLLER FOR DISK FILES        Abstract A microcontroller for controlling the bidirectional transfer of data between a control unit and a plurality of disk drives is disclosed.  The microcontroller has a fixed machine cycle time for executing each instruction and is arranged to fetch the next instruction during the execution of the current instruction.     The microinstructions are stored in an addressable memory and each addressed instruction is transferred to a control subsystem in response to the operation of a second subsystem whose function is to generate the address of the next instruction to be executed. A third subsystem is provided for executing the instructions which is also employed during branch type of instructions for assisting the second subsystem in generating the next address.     The second subsystem also functions to supply the third subsystem during execution of certain instructions, data to be stored for use during subsequent instructions.     The subsystem for executing instructions is characterized by a plurality of data sources which are selectively interconnected through the ALU to the ALU register during the input phase of a machine cycle and a plurality of data destinations which are selectively connected to the output of the ALU register during the output phase of a machine cycle.  One of these destinations is the subsystem for fetching the next instruction.       The subsystem for fetching the next instruction is characterized by a plurality of partial address generators which operate selectively with the other subsystem to generate the complete address of the next instruction.       The controller also employs a multilevel priority trap system for interrupting the normal sequencing of instructions in response to events occurring in the devices being controlled or events within the microprocessor.
