Abstract: INK RIBBON CARTRIDGE, CARTRIDGE REFILL AND METHOD OF LOADING SAME    ABSTRACT OF THE DISCLOSURE This specification discloses an apparatus and method for transporting, loading, and reusing an inking ribbon in a printing means such as a wire matrix data printer.  The invention reduces jamming and binding of the inking ribbon and promotes easy and effective loading, and it thus improves the operation of the overall printing device itself.  The disclosure includes a ribbon cartridge which has a narrow and configured outlet opening which provides an exit from a central storage area which ideally allows only a single thickness of ribbon to exit from the cartridge.  Thus, ribbon can be loaded into a cartridge as a circular spool, stripped from the spool within the cartridge, removed from the cartridge through the exit and stuffed back into the cartridge to form a rectangular ribbon pack within a generally rectangular storage area within the cartridge.  If desired, the rectangular ribbon pack can be removed from one ribbon cartridge and shipped in that form, for loading into a second ribbon cartridge at some other location.

Abstract: PIVOTING DUAL LAND WHEEL FOR A PLOW              Abstract of the  Disclosure A land wheel assembly including dual wheels pivotally mounted on a vertically positionable arm of an implement such as a plow.          When the arm is lowered and the plow is in the transport position the wheels can rock in a castering fashion about a pivotal axis having a substantial vertical component so that as the implement is turned around a corner, the wheels caster to reduce tire scuffing and stresses in the assembly.  When the arm is raised to lower the implement to the ground-working position, the pivotal axis shifts, approaching a generally horizontal attitude and allowing the wheels to pivot up and down with respect to each other about the axis to provide an even plowing depth and reduce stresses throughout the assembly on uneven ground.

Abstract: PEN.9419                  20 ABSTRACT         A method of manufacturing an IGFET device in an entirely self-registering manner, in which on the semi-conductor body a narrow silicon nitride strip is formed which cover  only the active region of the body and the width of which is substantially equal to that of the transistors to be manufactured and possibly other circuit elements.  This nitride strip is used as a mask for providing the channel stopper zone and as an oxid-ation mask for providing a first oxide layer.  The nitride strip is then etched in which the strip is locally removed over its entire width and only parts remain above the channel region and contact regions which form a second oxidation mask and, in cooperation with the first oxide layer, a doping mask.  The source and drain zones of the transistors and possibly further zones, for example underpasses, are formed via said doping mask after which by oxidation a sunken oxide pattern 18 formed over the whole surface with the excep-tion of the channel regions and the contact regions. After the oxidation the remaining nitride may be removed by means of a maskless etching treatment after which the gate dielectric with the gate electrodes can be provided in a simple manner above the channel regions and the contacts, possibly preceded by the provision of contact zones, can be provided in the contact regions.

Abstract: ABSTRACT           Cassette changer apparatus for a machine for recording and playing back information on magnetic tape contained in a cassette when located in an operative posi-tion.  The cassette changer apparatus has a cassette storage magazine and cassette loading apparatus for transporting cassettes between the magazine and the operative position in the machine.         A turntable supports the magazine for rotation about an axis extending through the inverting axis for a cassette in the magazine, so that operating the turntable to rotate the magazine one-half revolution inverts a cassette therein and positions both sets of recording tracks on tape in the cassette upon transport to the operative posi-tion for use with a mechanism providing playback and/or recording upon a single direction of tape movement.  The magazine in preferred embodiment has a plurality of compart-ments and is translatable to bring any compartment and cassette therein to loading position.  Coded elements in a band on the outer surface of the magazine are scanned by optical pick-ups to produce output signals, and control circuits use such output signals to control the magazine movement and locate a selected cassette compartment in loading position.

Abstract: ABSTRACT The specification discloses a mobile home heater taking combustion air from the outside and operable selectively as a stove and a fireplace and being double-walled in its back sides and bottom.  In operation as a stove, combustion air flows into a bottom passage covering the bottom of the fire chamber, up a back passage covering the back of the fire chamber and down a preheating passage in the back passage and into the lower portion of the fire chamber, secondary air also flowing from the back passage into the upper portion of the fire chamber.  For fireplace operation, a door is opened to the fire chamber and also opens ports from the bottom passage to supply air through the door opening, a thermostat controlled damper to the preheat-ing passage closing.  An injection tube leads from the back passage into a stack to minimize condensation in low combustion operation and a second air injuction tube in the upper portion of the stack has a thermostat controlled inlet valve closed when the stack is hot.

Abstract: ABSTRACT A modular terminal system employs a CPU module connected via a bus to at least one slave module.  An error condition is detected if a slave module fails to respond to a command by generating an operation acknowledge signal within a predetermined period of time associated with the time requir-ed for the slave module to execute the command.  A memory mapping device is utilized to decode CPU address signals and generate related signals on a greater number of output lines coupled to the system bus thereby increasing the number of addressable locations otherwise accessible by the CPU.  Im-proved prioritized bus communication is provided by way of a vectored inter-rupt scheme in which a priority line is coupled in a daisy chain fashion to other slave modules in the system.  In the preferred embodiment the system employs distributed CPU modules employing an interprocessor interrupt tech-nique utilizing a pair of commonly accessible storage devices.  One of the processors may be used as an emulator and a programmable logic array is advantageously utilized in the emulator processor.

The whole transmission is directly couplable to the drive engine (1) by way of a clutch (3). Engines with differing r.p.ms and outputs can be reduced to the same r.p.m. by means of the back-gear stage (6,7). The power take-off stage (10,11) arranged on the layshaft(6) of the back-gear stage (6,7) and having a clutch device (9) drives a reduction gear (14), at which the drive pinion shaft (15) and the output gear shaft (16,17) are led outside the housing of the reduction gear (14). In this way these shafts (15; 16,17) rotating at different r.p.m. can drive different working devices, which can be driven whether the vehicle is travelling or stationary by virtue of the controllable power take-off (10,11).
