Abstract: A MARKOV PROCESSOR FOR CONTEXT ENCODING           FROM GIVEN CHARACTERS AND FOR CHARACTER                DECODING FROM GIVEN CONTEXTS                  Abstract In an apparatus for generating variable length codewords c(aj) and c(aj) responsive to corresponding fixed length codewords b(ai) and b(aj), where ai and aj are source alphabet characters, ai.epsilon.Al and aj.epsilon.A2, ambiguity arises whenever any fixed length charac-ter to be encoded can instantaneously represent source characters aj and aj drawn from two or more dissimilar alphabets i.e., A1 or A2.  This is resolved by the inclusion of a Markov processor in com-bination with the apparatus.  The processor establishes the point in the sequence when transitions occur between fixed length char-acters in one alphabet to fixed length characters in another alpha-bet by the message context.  The processor includes a map of state and transition paths.  This map models certain statistical regulari-ties of runs of fixed code elements and the relative likelihood that an ambiguous fixed code character appearing in a first run belongs to a given alphabet.  The processor, starting from an arbitrary initial position, tracks any given run of fixed code characters applied to the encoder in terms of a succession of states and paths.

Abstract: ABSTRACT OF THE DISCLOSURE           A process for casting on a support the faithful shadow of a mask pierced with periodically distributed slits.  This process is particularly useful in photolitho-graphy.  In the process the wavelength of a flat incident wave is chosen so that there exist only two diffracted orders for each of the two half-spaces defined by each slit and which are situated on each side of a mean plane of the mask midway between the exterior surfaces thereof.  The angle of incidence of the flat wave is adjusted so that the reflected diffracted order which is not the specularly reflected order is propagated in the direction of the incident wave but in the opposite direction.

Abstract: RECORDING SYSTEM & METHOD               ABSTRACT OF THE DISCLOSURE      The invention pertains to a recording system and method for recording dictation on a recording medium including a recording device, wherein controlled motion of the medium is provided in either a forward or a reverse direction relative to the recording device.  Voice-generated dictation signals can be transmitted to the recording device for recording on the medium while the medium is moving in the forward direction, and voice-generated instruction signals may be selectively transmitted to the recording device for recording on the medium while the medium is moving in the forward direction. The termination of operation of the instruction signal transmission initiates a return by moving the medium in the forward direction until the farthest point along the medium at which dictation signals have previously been recorded is reached at the recording device. The dictation signal transmission is rendered inoperative during operation of the instruction signal transmission and during the return operation.

Abstract: RAISING AND LOWERING MECHANISM FOR FARM IMPLEMENT              Abstract of the Disclosure A tractor-drawn farm implement is carried at its front end on a tractor drawbar and at its rear end by trailing wheel means, and linkage of the so-called four-bar type is operative to selec-tively raise and lower the implement.  The body of the implement serves as one member of the linkage and front and rear lever arms are interconnected by a leveling rod so as to coordinate the front and rear arms as force is exerted against one arm by power-operated means on the implement.  During one phase of vertical movement of the implement as it is raised or lowered, the leveling rod is stressed in compression.  The invention provides yieldable means in conjunction with the rod capable of yielding as to prevent or at least minimize bending of the rod in the event of over-stressing.

Abstract: SOLAR HEATER SYSTEM AND VALVE A Solar Heater system including an absorber panel having an inlet and an outlet connected to a water supply tank. A valve is located in both the inlet and outlet connections and at least the inlet valve is temperature responsive so as to close when the temperature of the panel contents falls below a first predetermined temperature. The outlet valve may be temperature or flow responsive so as to close under the temperature or flow conditions prevailing when the inlet valve closes and thereby isolate the panel from the tank. A temperature responsive dump valve is connected to the panel and opens when the temperature of the panel contents falls below a second predetermined temperature which is lower than the first predetermined temperature and thereby empties the panel contents. The inlet and dump valves are preferably formed by a single combination valve having a temperature responsive element which controls both a primary valve member and a secondary valve member. The primary valve member controls flow between inlet and outlet ports of the valve and the secondary valve member controls flow between the outlet port and a dump port. The temperature responsive element has part thereof exposed externally of the valve body and is substantially insulated against the influence of the temperature conditions existing within the body of the valve.

Abstract: DATA SET NETWORK DIAGNOSTIC SYSTEM            Abstract of the Disclosure A voiceband data set network includes a control data set, a plurality of tributary data sets and a diagnostic control device.  User-provided data is communicated between the control data set and the tributary data sets via a primary channel within a four-wire private telephone line.  Diagnostic and control information is communicated between the control data set and the tributaries via a secondary channel within the private line.  Diagnostic and control information is communicated between the diagnostic control device and the control data set, with which it is co-located, via a control channel. Each data set includes a data set diagnostic unit, or DDU, via which it transmits and receives the diagnostic and control information.  Communications among the DCD, DDUs, and primary controllers within the data sets, are carried out on a link-by-link basis, with the DDUs serving as message switching nodes and with communications over each link being principally comprised of requests and reads. The DCD, DDUs and primary controllers communicate in a hierarchy in which requests and reads are always directed downstream.  The tributary data sets provided, however, with a way of directing request-type message texts upstream.

The two elongate members are hinged together at a pivot location which, when the elongate members are secured to the legs can be substantially aligned with the hypothetical pivot axis between the upper and lower leg.  A tension member is secured between a first location which moves with the first member and a section location which moves with the second member, the force of the tension member acting along a line which is spaced from the pivot location and which is such that tension in the tension member increases as the leg is flexed.  In this manner, the moment acting to extend the leg increases as the leg is flexed.
