Abstract: Abstract Provided are an apparatus and a method for re-cording on a recording medium images from a fiber-optic CRT.  The apparatus includes a recording medium transport system, control electronics and a first in, first-out memory.  The use of the first-in, first-out memory permits incremental recording which is not limited by relatively long mechanical transport set-tling times.  In operation, N lines of data are input to the memory, line-by-line, as the transport system increments the position of the recording medium and during settling time.  When the recording medium has come to rest, these N lines of data are output se-quentially from the memory in a first-in, first-out basis, with the CRT incrementing each line vertically on the recording medium for the total of N lines for each increment of the recording medium by the transport system.

Abstract: Abstract Disclosed is a method of forming in a monocrys-talline silicon body an optimum recessed oxide isola-tion structure with reduced steepness of the bird's neck.  Starting from a monocrystalline silicon body, there is formed thereon a layered structure of first silicon  dioxide,  polycrystalline  silicon,   second silicon dioxide and silicon nitride,  in that order. The  layers  are  patterned to  form openings  in  the structure at the areas where it is desired to form the oxide isolation pattern within the silicon body.  The exposed areas of the silicon body are anisotropically reactive  ion  etched  to  an  initial  portion  of  the desired depth obtaining the corresponding portion of the trench having substantially vertical walls.  Then by chemical etching the trench is extended to a final portion of the desired depth obtaining inwardly sloped walls in the final portion.  The body is then thermal-ly oxidized until the desired oxide isolation pene-trates to the desired depth within the silicon body.

Abstract: TTL TO CMOS INPUT BUFFER            Abstract A TTL to CMOS input buffer is disclosed which prevents static current flow when the TTL input signal is at a relatively low voltage logic "1" state.  A transition detector (44) responsive to the input TTL logic signal and a voltage boosting circuit (50) connected between a positive power supply (VDD) and the input to a first CMOS inverter (30) are utilized to sense an input signal "0" to "1" transition and boost the TTL logic "1" signal to a voltage level which will prevent the p-channel transistor (32) included in the CMOS inverter from turning "on".  The voltage boosting circuit is subsequently disconnected from the input to the p-channel transistor to prevent the input from being fully charged to the positive power supply. (FIG. 3)

Abstract: PNEUMATIC PRESS CONTROLLER AND METHOD                ABSTRACT OF THE DISCLOSURE         A controller and method are provided for con-trolling pneumatic presses, and similar machines.  The controller comprises a gauge to measure increments of stock length passing through the press, a length recorder to set the desired piece length, and a length comparator which compares the readout of the gauge with the preset recorder piece length, and when equal, generates a stroke initiate signal.  The stroke initiate signal opens an air valve portion of the pneumatic press to communicate pressurized air with the power side of an air actuated ram, which in turn converges the press platens to perform the desired press function, such as punching holes, notching, cutoff, or the like.  The controller also includes a timer to measure time beginning from the stroke initiate signal, a time recorder to set the time the air valve is to remain open, and a time comparator which compares the readout of the timer with the preset valve open time, and when equal, generates a stroke halt signal.  The stroke halt signal closes the air valve to cease extension of the ram, and permit the platens to automatically diverge by means such as return springs, or the like.  The stroke of the press is varied in accordance with each selected press operation and application to minimize press cycle time, and to increase production speed.

Abstract: ABSTRACT          A metering valve (20) for supplying a turbine engine with a fuel at a substantially constant flow rate in response to operational conditions evaluated by a computer (28).  A signal from the computer (28) in the form of voltage pulses is supplied to a solenoid (30).  The solenoid (30) regulates the flow of fuel from a control chamber (54) to produce a fuel pressure Px therein.  The fuel enters a supply chamber (46) and the fuel pressure P1 thereof acts on the effective area of a first diaphragm (42) to move face (70) on plunger (68) away from seat (38) in opposition to a closing force generated by the fluid pressure Px acting on a second diaphragm (48).          A feedback valve (90) regulates the flow of fuel from supply chamber (46) to control chamber (54).  By making the size of the first diaphragm (42) one half the size of the second diaphragm (48) when Px is equal to one half of the sum of fuel pressures P1 and P2, an equilibrium condition exists and fuel is supplied to the outlet conduit (40) at a substantially constant rate for distribution to a turbine engine.

Abstract: ABSTRACT    The invention relates to a method for thinning a forest by means of a wheeled harvester and a wheeled forwarder comprising a driver's cab and a load carrier located behind the cab. The harvester (3) is caused to advance in existing forest stands (1) in routes optimally selectable with regard to the characteristics of the stand, between main haul roads or strip roads close to each other, and is parked on suitable places along the routes for felling trees on each parking place. The trees are limbed and placed underneath the harvester between the wheels thereof, and the forwarder (4) is caused to follow the harvester in the same route as this and take care of the tree stems placed underneath the harvester and left behind it. This is achieved in that the felled trees lying in front of the forwarder are lifted by it and moved over and rearwards past the cab of the forwarder to the load carrier situated behind the cab. As the for-warder is advanced along the route, it collects the tree stems for landing them at a suitable main haul road.            Fig. 1 elected for publication

Abstract: ABSTRACT OF THE DISCLOSURE           A method and apparatus for determining electrochemically active components in a process stream.  The method comprises the steps of providing a sample in which the components are contained, and depositing the components onto a working electrode, altering the environment of the working electrode so that it is immersed in a supporting electrolyte by effecting a matrix exchange and stripping the deposited electrochemically active components from the working electrode into the supporting electro-lyte.  The method and apparatus utilize a measurement cell which comprises a vessel for containing the supporting electrolyte and a mercury drop electrode. A flow injector is used to inject a flow of a sample electrolyte which contains the electrochemically active components into the vessel so that the sample electrolyte surrounds the mercury drop electrode and then sinks away from the mercury drop electrode to the bottom of the vessel where it is removed via an outlet to thereby leave the mercury electrode immersed in the supporting electrolyte.  The deposited impurities are stripped from the supporting electrolyte using variable time domain transient electrochemical stripping volt ammetry.  The sequence of steps including the deposition of the impurities from an injected flow of electrolyte sample are repeated under microprocessor control.

Abstract: An apparatus for feeding of two different webs of material, for example, film strips, which can be brought up to a cutting station H each from their own feed roller F, G and their own set of feed elements A1, A2, D1, D2. The two feed rollers A1, D2 which lie between the two webs of material are idler rollers, and between them is placed an intermediate wheel M, such that an active portion of the wheel's periphery just touches the two idler rollers, whereupon a forward feeding by the one set of feeding elements gives rise to a backward feeding by the second set of feeding elements. Since the periphery of the intermediate wheel M is divided into an active and inactive part, there is a relatively short back feeding of the material web which is not cut. In this way, one can prevent the one web during its forward feeding pulling the other web somewhat into the cutting station. <IMAGE>
