Abstract: ABSTRACT OF THE DISCLOSURE          A cutter for picture frame mats is provided herein.          It includes a rectangular cutter base having a planar mat-supporting surface.  The cutter includes a novel clamping frame having a pair of transverse lateral hinge bars and a novel cutter head guide bar assembly secured thereon, i.e., the cutter head guide bar assembly is pivotally mounted with respect to the transverse, lateral hinge bars.  A cutter head is slidably mounted along the guide rod by means of a replace-able bearing block formed, e.g., of OILON, the cutter head having a pair of cutting blades movably carried by the cutter head.  A pair of spaced-apart, longitudinally adjustably movably detachable stop means is mounted on the cutter head guide bar assembly to limit to-and-fro slidable movement of the cutter head along the guide bar.  The transverse, lateral hinge bars thus enable a user to rotate the cutter head guide bar assembly and the clamping frame between and upright position (at an angle of from 92 - 96°  to the plane of the cutter base), and a lowered position (in which the bottom surface of the guide plate is flush with the mat-supporting surface).  The clamping frame is selectively deformable to enable downward pressure to be exerted on the guide plate, thereby to grip the picture frame mat.  A mat guide system is also mounted on the cutter base to enable duplication and repeating of the same cutting procedures through a series of three steps in a duplic-ation, repeater and groover mounted on a wide rigid central bar is also provided.

Abstract: ABSTRACT OF THE DISCLOSURE           Disclosed is a two wire frequency division multiplex system.          The system comprises two kinds of multiplex stations connected by two wire lines and distinguished by two different predetermined frequency basebands each of which consists of predetermined frequencies for dividing the multiplex channels.  The multiplex stations are provided with conversion means in their respective transmit paths such as to convert their own basebands to the different ones of the other multiplex stations connected and vice-versa.  The system preferably provides generalized units in both kinds of multiplex stations and is simpler than a known one which uses the same basebands in all multiplex stations and converts the baseband before and after transmitting.

Abstract: ABSTRACT OF THE DISCLOSURE     An identity band which comprises an elongate strap and a latch portion which forms a slot through which the strap is pushed to form the band into a loop.  The strap has a series of apertures therein providing a series of transverse stop surfaces alternating with a series of transverse camming surfaces.  Within the slot there is a latching element.  As the strap is pushed through the slot to form the loop, the camming surfaces in turn cam the latching element out of the path of the strap to permit passage thereof through the slot.  The stop surfaces are arranged so that, if an attempt is made to pull the strap in the opposite direction through the slot, one of them engages with the latching element to prevent such movement of the strap.  Both the stop surfaces and the camming surfaces meet the upper and lower faces of the strap portion at angles other than right angles.  The latch element is wedge-like and mounted at its thicker end.  The band is formed so that it can carry information identifying the person wearing the band.

Abstract: APPARATUS FOR INTERCONNECTION OF A MULTI-CHANNEL COMMUNICATION NETWORK                               ABSTRACT The present invention is directed to an apparatus inter-connecting a plurality of individual stations, such as telephone stations, to individual channels of a multi-channel communication network.  Prior art apparatuses are either relatively complicated, having multiple panels at which manual switching may be necessary, or have required that connectors which are subjected to repeated mating cycles be made up in the field, thereby adversely affecting network reliability.  The present invention provides a relatively simple termination module having a plurality of connector members each of which is identifiable with a given station and has a mating portion and a terminal portion.  The mating portion of the connector members mate with any one of a plurality of relocatable connectors coupled to and identifiable with a given communication channel.  The terminal portion of the connector members terminate the individual information transmission cables routed to the various stations.  The connector members are configured and mounted so that their  mating and terminal portions are accessible from one side of the module to facilitate field termination of the transmission cables and mating of the relocatable connectors with their respective connector members.

Abstract: WATER INJECTION PROFILING         (D#76,535-F) ABSTRACT OF THE DISCLOSURE         Water injection profiling of a well by nuclear log-ging is disclosed.  A dual detector sonde with a high energy neutron source and a spinner flowmeter is oriented and positioned above and below perforations in the casing of an injection well to monitor upward and downward flow, respectively, of injection water.  The water is irradiated by the neutron source and resulting gamma ray production is sensed as the activated water flows by the spaced detectors.  Count rate data is reduced and analyzed in terms of two energy windows to obtain linear flow velocities for water flow behind the casing.  Fluid flow within the casing is measured by means of the spinner flowmeter.  Volume flow rates are determined for upward and downward flow, and horizontal volume flow into the surrounding formations is calculated.

Abstract: ABSTRACT            A tuned acoustic directional transducer for transmitting and receiving airborne sound, which provides enhanced efficiency and reduced cost without undue narrowing of bandwidth, makes use of an acoustic transducer element coupled to a plate having a higher order flexural mode resonance at approxi-mately the desired frequency of operation, the plate being coupled to the air through low-hysteresis acoustic propaga-tion material having an acoustic impedance much less than that of the plate and much greater than that of the air.  The material is disposed so that in the desired direction of pro-pagation there is no substantial reduction of sound intensity in the far field resulting from cancellation occasioned by. interaction of sound radiated from adjacent antinodal zones. Preferably the thickness of the material is such that it acts as an efficient acoustic impedance matching transformer. Preferably, the transducer element is piezoelectric and coup-led to the centre of a circular plate to which the coupling material is applied in rings.

Abstract: LEVEL CONTROL CIRCUITRY FOR TWO WAY COMMUNICATION SYSTEM     ABSTRACT OF THE DISCLOSURE      Signals carried over a multiplexed transmission medium between first and second stations suffer transmission losses such that the signal one station generates has a substantially greater magnitude than the signal it receives from the other station.  A differential amplifier is utilized to extract and amplify the weaker signal thereby establishing signal balance.  Following the differential amplifier is an automatic gain control stage which includes novel sample and hold and activity checker circuitry.  The activity checker responds to the frequency of input signals to either allow variable gain control action or, when the frequency is representative of noise, to hold the gain control at its instantaneous value prior to the onset of noise.

Abstract: Abstract A stationary or mobile receiving bunker, which can be fed with bulk material by means of industrial trucks, for example dumpers, and which is provided with a delivery conveyor arranged under the receiving bunker, which draws the bulk material out of the receiving bunker.            Two bunker walls (8), which enclose the bunker chamber on the side awayfrom the direction of delivery (A), are so arranged, that the straight lines running through their top edges (11) and projected onto a horizontal plane each form an angle ?<c90°  with the longitudinal axis (12) of the delivery conveyor (2) also projected onto the horizontal plane.          This solution provides the advantage compared with known bunkers, whichcan be fed from more than one side, for example by means of dumpers, and which must therefore rest below the travelling floor of the dumpers, that the dumpers no longer have to drive in the immediate proximity of the edge of the slope and that the receiving bunker is distinguished by good manoeuvrability.

Abstract: MULTIPORT MEMORY ARRAY     Abstract of the Disclosure Dual port capability in a memory array is achieved by an arrangement of the memory cells such that for each cycle of the memory operation two accesses may be performed.  This result is achieved by taking advantage of the bit line precharging interval.  A second bit line accessing pair is added to each memory element, and each cycle is split so that when one bit line is in the accessing mode, the other bit line is in the precharging mode. The speed of the memory is effectively doubled by using this technique.
