Abstract: HIGH PRESSURE FEEDING                 ABSTRACT OF THE DISCLOSURE           A high transfer pressure device, and method, especially adapted for continuously conveying hard particulate material such as coal; and a screen specifically for use in such conveying.  The high pressure transfer device includes a pocketed rotor containing a pair of diametrically through-going pockets perpendicular to each other, a housing enclosing the rotor and having four ports spaced around the periphery thereof, and a screen operatively associated with the rotor or the ports for screening out particles above a predetermined size that are conveyed in liquid passed through the device. Preferably the screen is associated with one of the ports of the housing and fluid injection nozzles are associated with the screen for injecting liquid under pressure toward the screen to effect dislodgement of any particles that may be lodged in the screen and thereby prevent damage to the screen.  The operation of the fluid injection nozzles is timed to the rotation of the rotor.  Alternatively, a particularly designed screen made from bars that are square or circular in cross-section may be located in an enlarged middle portion of each of the pockets.

Abstract: ABSTRACT OF THE DISCLOSURE        A pipelined multiprocessing system including a main core memory and a shared write-through cache memory that maintains readily accessible copies of data in the main core memory.  A com-mon control unit (CCU) receives commands from the processors in a pipelined fashion thereby to control data transfers between the cache memory and the multiple processors, as well as between the cache memory and the main core memory in an ordered pipeline se-quence.  The CCU also performs updating and allocating operations of the cache memory located therein.  To improve data through put while sharing the cache memory, each processor connects to the CCU via a split-phase, bifurcated synchronous bus that carries address control signals in one phase and memory data signals in a differ-ent phase.  Since write commands do not immediately alter the cache memory, the CCU also includes a Processor Index RAM (PIR) for tempor-arily storing addresses sought to be written by each of the respect-ive processors.  When a processor issues a read command, it checks the contents of the PIR, and if the address sought to be read is one for which there is a write in progress by another processor, the CCU queues the read command for a subsequent access to the main core memory.  The CCU also includes a duplicate tag store that maintains a copy of the cache memory tag addresses so that the cache memory can be updated without the necessity to pipeline all write returns through the CCU to update the cache memory when writing data to the main core memory.

Abstract: ILLUMINATING DEVICE FOR PHOTOGRAPHIC COPYING APPARATUS            ABSTRACT OF THE DISCLOSURE    An illuminating system has as main components: a light source comprising four low voltage lamps and, as-sociated therewith, reflectors and condenser lenses, a filter unit, an image-producing pair of lenses, a deflecting mirror and light-mixing element made of glass. The condenser lenses produce images of the coils of the low voltage lamps in the central horizontal plane or the filter unit. Images of the condenser lenses are produced by the image-producing lens pair in a light entry face of the light-mixing element. This light entry face is provided with ribbings constituting cylindrical lenses of special dimensioning which effect homogenization of the light in the light-mixing element. In order to reduce light losses, the light-mixing element is composed of two frusto pyramidal element parts and has its smallest cross-sectional area in a middle region in which the smaller end laces of the frusto pyramidal parts are joined to an interposed diffusor disc. The filter unit comprises a pair of interference filters for each filter color. The filters of each pair can be driven by means of a stepping motor and cam disc to move symmetrically with regard to the optical axis. The illuminating device is of high light in-tensity and affords a particularly homogeneous light distri-bution.

Abstract: LOW VOLTAGE SENSOR FOR DRYER  ABSTRACT OF THE DISCLOSURE A fabric treating apparatus, such as a domestic clothes dryer, is provided with a microcomputer controlled circuit and a sensor system which cooperates to terminate a fabric treatment operation when the fabric reaches the desired condition.  A conductivity sensor senses the moisture content of the fabric within the drying zone.  A sensing circuit electrically connected to the sensor generates a voltage level proportional to the moisture condition sensed.          The microcomputer reads the voltage level at spaced intervals in time and generates a valid wet signal whenever a given consecutive number of readings indicate a wet condition of the fabric within the drying zone.  A counter within the microcomputer counts pulses from a source of timing signals and is repeatedly terminated and restarted whenever a valid wet signal is generated.  The fabric drying operation is terminated upon the accumulation of a preselected count in the counter such that the termination coincides with an optimum dryness condition.

Abstract: ABSTRACT         A limiter amplifier suitable for use in a paging receiver is described.  The amplifier does not use coupling capacitors and can therefore be manufactured as a monolithic integrated circuit.  Furthermore, it is capable of obtaining a favourable saturation characteristic even when operated by a low-voltage power source such as a single dry battery.  Finally temperature variations have virtually no effect on the new amplifier.  The amplifier comprises a power supply, two or more cascade-connected differential amplifiers for amplitude limiting and input.  Each differential amplifier has a first constant current circuit.  A biassing circuit is connected to an input of the cascaded differential amplifiers to supply thereto a biassing voltage. The biassing circuit has a second constant current circuit.  A third constant current circuit is provided for activating the first and second constant current circuits.  A voltage regulator is connected to the power supply a constant voltage to the three constant current circuits.  The voltage regulator has the same characteristic with respect to temperature variations as the three constant current circuits.
