Abstract: ABSTRACT OF THE DISCLOSURE      A memory subsystem which couples to a multiword bus for processing memory requests received therefrom includes at least a pair of independently addressable dynamic mem-ory module units.  Each memory unit includes a number of rows of random access memory (RAM) chips. The subsystem receives as part of each memory request an address, the least significant portion of which selects the row of chips to be accessed within one of the pair of memory units.  Address decode circuits include gating circuits which couple to both module units.  The gating circuits are interconnected so that the decoding of the least significant address bits results in the generation of a pair of row address strobe signals.  These signals enable simultaneously the rows of RAM chips for access within both module units for read out of information to a multi-word bus eliminating any delay in address incrementing.

Abstract: PRESSURE REGULATOR FOR INJECTION SYSTEMS OF CONTROLLED IGNITION INTERNAL COMBUSTION ENGINES                       ABSTRACT          The purpose of a pressure regulator for injection systems is to control the fuel feed pressure to the injectors by comparing it constantly with a set value, in order to keep the air/fuel mixture ratio correct under all engine operating conditions.       In general, it consists of an arrangement of various mechanical components which act in order to divide the fuel stream delivered by a pump into two unequal parts.          One part of this stream is made available to the injectors, which absorb that quantity required by the engine operating condition&. The remainder is returned to the vehicle tank.

Abstract: GAIN CONTROL CIRCUIT               ABSTRACT OF THE DISCLOSURE           A gain control circuit, which has particular utility in a compressor or expander of a noise reduction circuit, is comprised of first and second detectors for detecting the output signal from a variable gain amplifier and providing respective detector outputs for charging first and second capacitors, respectively.  Such first and second capacitors have discharge paths in which first and second resistors are respectively interposed, and the charge on the first capacitor is employed as a control signal for determining the gain of the variable gain amplifier.  Further, the first resistor is connected between the first and second capacitors so that the discharge current through the first resistor is dependent on the difference between the charge voltages on the first and second capacitors, whereby a relatively  long recovery time can be obtained without adversely affecting the attack time even when the input signal to the variable gain amplifier is of low level.

Abstract: ABSTRACT      A storage rack has vertical posts with vertically spaced apertures.  Rails extend horizontally between the posts and are locked onto them by means of mounting plates on the ends of the rails.  Each mounting plate has a pair of contiguous perpendi-cular planar surfaces that receive the edge margin of the post in the corner that they provide.  The rail extends from one of the planar portions of the mounting plate, while the other planar portion has apertures through it that are aligned with apertures through two parallel walls of the post.  The free ends of the legs of a generally U-shaped connector extend through these holes and are fastened at the exterior surface of the apertured mounting-plate portion by nuts.  Exteriorly of the opposite post wall, the U-shaped connector has an offset web portion that extends perpendicularly of the leg portions beyond the edge margin of the post and around a narrowed tongue por-tion of the mounting-plate portion from which the rail extends.          The connector web portion bears against the mounting-plate tongue portion at the same time that the nuts bear against the apertured mounting-plate portion, so tightening of the nuts causes fastening force on the mounting plate in two directions.

Abstract: DOWNHOLE STEAM GENERATOR HAVING  A DOWNHOLE OXIDANT COMPRESSOR   ABSTRACT OF THE DISCLOSURE Apparatus and method for generation of steam in a borehole for penetration into an earth formation wherein a downhole oxidant compressor is used to com-press relatively low pressure (atmospheric) oxidant, such as air, to a relatively high pressure prior to mixing with fuel for combustion.  The multi-stage compressor receives motive power through a shaft dri-ven by a gas turbine powered by the hot expanding com-bustion gases. The main flow of compressed oxidant passes through a velocity increasing nozzle formed by a reduced central section of the compressor housing.  An oxidant bypass feedpipe leading to peripheral oxidant injection nozzles of the combustion chamber are also provided. The downhole compressor allows effective steam generation in deep wells without need for high pressure surface compressors.  Feedback preheater means are provided for preheating fuel in a preheat chamber. Preheating of the water occur s in both a water feed line running from aboveground and in a countercurrent water flow channel surrounding the combustor assembly.  The countercurrent water slow channels advantageously serve to cool the combustion chamber wall.  The water is injected through slotted inlets along the combustion chamber wall to provide an unstable boundary layer and stripping of the water from the wall for efficient steam generation.  Pres-sure responsive doors are provided at the steam outlet for closing and sealing the combustion chamber from entry of reservoir fluids in the event of a flameout.

Abstract: Abstract A method for feeding a fibre suspension onto the wire of a web former through a guiding device consisting of a plurality of guiding channels through which the fibre suspension flows parallelly and which are connected to a slice chamber leading to a slice and extending across the wire of the web former. A means for separating the dilute border part of the jet of stock flowing in from every single,flow channel is disposed after upstream of the guiding device. The outer portion is deflected from the direction of flow of the thicker and more homogenous core part and by letting the latter proceed up to the lip substantially maintaining its direction, a situation is reached, whereby considerably less local consistency variations occur in the lip flow across the head box. Pre-ferably, this means is formed by a plate in which there are openings disposed coaxially with regard to the manifold tubes so that the diameter of the openings of the plate is smaller than that of the openings of the tubes.
