Abstract: TITLE OF THE INVENTION                 "MICROWAVE PREAMPLIFIER"                ABSTRACT OF THE DISCLOSURE      An input matching circuit for a first stage amplifying element of a microwave preamplifier comprises at least one capacitive open-ended stub which is located in the vicinity of an input terminal of the first stage amplifying element so that the structure of the input matching circuit is simple.  Input impedance of the first stage amplifying element is designed to assume a state of impedance matching for minimum noise, while the distance between the first stage amplifying element and a second stage amplifying element is appropriately determined with an input matching circuit of the second stage amplifying element being appropriately set.  With this arrangement input VSWR of the preamplifier is set to a value smaller than an input VSWR of the first amplifying stage, and therefore it is possible to provide a microwave preamplifier which shows satisfactory input VSWR characteristic and noise figure such that the input VSWR of the preamplifier is improved when compared with the input VSWR exhibited on impedance matching for minimum noise while the noise figure is less deteriorated compared to the noise figure exhibited on impedance matching for minimum noise.

ABSTRACT OF THE DISCLOSURE        A  method   is   disclosed   for   controlling simulated moving bed system of a type including at least four  series-arranged  beds  each  packed  with a  solid adsorbent,  with  the downstream end of each bed and the upstream   end of the next succeeding bed being connected by conduits to form an endless loop, and in which a fluid is caused to circulate through the beds in one direction, a  feed  stock  and  a  desorbent  are  introduced  into  the system while a raffinate and a sorbate are withdrawn from the  system,   and  the  positions  of introduction  and withdrawal of  the  four  kinds of  fluid  are periodically shifted in the direction of the circulating  fluid flow.          In accordance with the invention, two or more circulating pumps,  provided  with  variable  speed  controllers  and pressure detectors for detecting the suction pressure of each of the circulating pumps,  are disposed between two beds.    The  flow  rates  of  three  of  the  four  fluids introduced into or withdrawn from the system are adjusted to predetermined values,  and the flow rate of the other fluid  is controlled  in  such  a manner  that  the  suction pressure of one of the circulating pumps or the average of the suction pressures of two or more of the circulating pumps is held constant, and a rotational speed of each of the circulating pumps is controlled independently so as to control  the  flow  rate  of  the  circulating  fluid  and  to maintain the suction pressure of each circulating pump at a low level.

Abstract: Abstract of the Disclosure A peripheral interface system is disclosed.  An input-output processor is provided to receive input-output commands  from  a  central  processing  unit.   Up  to  four multiplexing units may be connected to the input-output pro-cessor, with each multiplexing unit providing an interface for up to  four controller units,  which may be used to control a peripheral device.  The multiplexing unit includes a pair of data buffers, each with its own addressing cir-cuit, and each functionally divided into four storage areas, each storage area providing four registers to store four parcels of data.  Data is transferred between the input-output processor and the controller units by filling the storage area in a buffer from the local memory of the input-output processor in a serial fashion over a DMA channel pro-vided between the multiplexer and the local memory.  Data transferred from the storage area in the multiplexer to a controller is sent one parcel every four clock periods, according to a scanner/time slot synchronization scheme bet-ween the multiplexer and the up to four controllers which may  be  connected  thereto.   Similarly,  data parcels  are transferred from the controller to the multiplexer on a scanner/time slot basis,  and from the storage area of the multiplexer to the memory in a serial, consecutive fashion over the DMA channel.   In operation,  the buffers of the multiplexer are alternately filled and emptied such that one may be filling while the other one is emptying.  A pair of buffers are also provided in the controller unit, which also may  be  alternately  filled  and  emptied  as  between  the peripheral device and the multiplexer.

Abstract: ABSTRACT OF THE DISCLOSURE            A speech recognition method and apparatus in which a trajectory drawn by a plurality of time-sequential acoustic parameters obtained from segmented speech signals in the parameter space thereof time-normalizes the segmented speech signals and this trajectory is matched with a standard time-normalized trajectory, which was previously registered, to perform the speech recognition.  A silence acoustic parameter can also be added to the time-sequential acoustic parameter produced from the segmented speech signals to obtain the trajectory thereof.  The length of the trajectory formed from the segmented speech signals is determined and is used to select the previously registered standard trajectory to be matched.  Therefore, in addition to checking the distance between the segmented speech trajectory and the registered standard trajectory to obtain a match, the lengths of the two trajectories are also taken into account, thereby increasing the recognition ratio.

Abstract: ABSTRACT OF THE DISCLOSURE     A method of injection of wire into molten steel wherein a coil of the wire is positioned around a mandrel, and the wire is pulled from the coil in the axial direction of the mandrel and is fed by transport means into the molten steel.  To avoid the need to rotate the coil and yet to achieve smooth uncoiling and also to permit two coils to be uncoiled successively without interruption the coil is a self-supporting parallel-wound coil, which is resiliently clamped around at least part of its outer surface over its whole axial length.  The axial length of the mandrel is greater than that of the coil and, at the start of uncoiling of the coil there is a gap of at least 5 cm between the inside surface of the coil and the mandrel.  The wire is pulled from the inside of the coil from the inside of the coil through a ring which is mounted around the mandrel axially spaced from the coil and which has a slot-shaped radial extension open to the interior of the ring.  The wire end on the outside of the coil is connected to the wire end on the inside of a further such coil through the said slot-shaped radial extension.

Abstract: ASSEMBLY WITH SEPTUM FITTING FOR CONNECTING ADAPTOR AND FLUID TUBE                                         BY: CRAIG M. WHITEHOUSE     DANIEL R. SNYDER RONALD B. LUTHER            ABSTRACT OF THE DISCLOSURE:      An assembly for connecting needles and catheters in I.V. applications, chemical analysis, etc., includes a leak proof, sterile, self-sealing septum from which the needle is inserted. When the needle is retracted  from   the septum, the septum will reseal and thus maintain a seal-proof, sterile seal. The assembly is therefore reuseable, and this represents a considerable cost saving for patients who require continuous therapy such as with diabetics, cancer patients, and the like.      The assembly includes a distal end haying an outlet bore through which a catheter is inserted.  The proximal end of the assembly is connected to an external adaptor to which is attached a needle.  The septum is positioned between the distal end and the proximal end to provide a self-sealing seal between the needle and the catheter.  This external adaptor with needle may be part of a syringe or shaped to accommodate any standard connector such as a luer lock.      Depending on the application, the fittings may be manufactured from a wide range of materials including plastics and metal. For example, as an inexpensive disposable item, the fitting would preferably be manufactured from molded plastic.

Abstract: ABSTRACT A chimney cap has a roof, a screen beneath said roof and legs extending downward beyond said screen when the cap is in an upward position. Preferably, there are four legs on each cap and the legs are bendable and sufficiently resilient so that said cap can be installed by forcing it downward on a flue.  In this position, the legs exert sufficient outward pressure against interior walls of said flue to retain said cap on said flue.  The screen occupies a space between the roof and an upper edge of said flue.  The cap is removable by exerting an upward force on said cap so that the legs will slide relative to the interior walls of said flue.  Thus, the cap can be readily installed on or removed from the flue without the use of tools.
