Abstract: ABSTRACT A wind machine turns a shaft to activate a multistage positive dis-placement pump having intake and discharge valves respectively coupled to intake and discharge fluid lines in a recirculating hydraulic system.  A controller regulates the operative positions of the intake valves, discharge valves or separate idling arrangement to remove selected stages from effective pumping while at the same time fluid passes into and from the selected stages.  The stages can be of different capacities and selected groups or all of them may be periodically idled by a common or individual idling arrangement.  A constrict-ing valve is located in the common discharge line from all stages and can be additionally located in each discharge line from each stage.  Automatic control of torque on the wind rotor shaft by the idling and constricting means permits the rotor to start to rotate, continue to rotate at a speed for maximum efficiency conversion of the wind power into hydraulic power over any desired range of wind speeds, rotate as limited to any specified maximum rates rotation during high wind speeds, and to stop and lock if the wind speed becomes excessive.  The hydraulic system can parallel-connect a number of wind machines to drive a single turbine installation to produce useful power.

Abstract: TURN-OFF CONTROL CIRCUIT FOR SELF-CLEANING OVENS  Abstract of the Disclosure In a cooking oven which is cleaned by pyrolyzation of soil within the oven cavity and has a smoke eliminator duct extending through the oven wall, with a smoke eliminator heater disposed adjacent to the duct inlet, a reducing gas sensor is mounted either adjacent to the oven end of the smoke eliminator duct or within the smoke eliminator duct near its discharge end.  An electrical relay or microcomputer control is coupled between the gas sensor and the heater to initially heat the oven interior and to later deenergize the heater when the reducing gas sensor output indicates a desired oven condition.  The oven heaters are temporarily deenergized when the gas sensor output indicates a smoke eliminator overload. If the gas sensor is mounted in the smoke eliminator duct, the smoke eliminator heater may be deenergized toward the end of the cleaning cycle, so that the effluent is not affected by the smoke eliminator heater before reaching the gas sensor. Plural smoke eliminator heaters are also disclosed to enable increase of heater power during the early cleaning stages and reduction of the heater power during the later cleaning stages.

Abstract: OPTICAL PROJECTOR             ABSTRACT OF THE DISCLOSURE     An invention is disclosed for optically determining the position of an object in spacer using a single lens for triangulation, wherein an indexing light beam is projected to a lens on one side nonparallel to the optical axis of the lens.  The lens focuses the indexing light beam at a known point on the other side of the lens at or near which reflection occurs by the object.  Reflected light is captured by the lens and focused toward a photodetector which generates a signal indicating whether reflection occurred at the known point, thus indicating whether the object is present at the known point.  If laser light is used, provision is made for, in effect, positioning the laser light source on the optical axis to reduce the effects of laser pointing instabilities. The invention can be used to measure the radii of rotating gas turbine engine rotors.

Abstract: Abstract of the Disclosure Video control circuitry for controlling the video format presented to the cathod ray tube or screen and capable of providing a combination of character generation and cell generation along with other video types of control.  The video controller may comprise a video memory means for controlling writing into and reading therefrom and means defining both a memory address and a memory data.  There is a video data bus coupled to the video memory means and a processor address bus. A cathode ray tube controller has address lines and the address lines are connected to multiplexer means for selecting either the the controller address lines or the processor lines. Control means are provided for controlling the multiplexer means so that in one state thereof the video memory means is addressed from the cathode ray tube controller means and in the other state the video memory means is addressed from the central processing unit address.  This occurs on an interleaved basis with the CRT clock basically operating at the normal refresh cycle rate.  However, in accordance with the invention the CRT clock is essentially divided so that one half of the clock cycle is used for communication from the CPU to the video memory means.  This provides for improved screen display.

Abstract: Abstract A bit compression multiplexer for a pair of time division multiplexed digital bit streams each one of which includes a plurality of PCM encoded signals deposited in separate and distinct channels and signaling bits multiplexed therewith.  The encoded signals are bit compressed, and then multiplexed and grouped into clusters. Each of the multiplexed compressed signals occupies a separate and distinct channel of a repetitive frame that includes a plurality of clusters and a corresponding number of additional channels, called delta channels, each one of which is associated with a given cluster and is proximate thereto.  The signaling bits are extracted from the pair of digital bit streams, reformatted and then placed in predetermined bit positions of the delta channels.  The signaling bits in a given delta channel are associated with the compressed signals of a cluster proximate thereto.  The combination of a cluster and its related delta channel comprise a bundle.  A framing bit pattern is developed for each bundle and the framing bits are placed into a predetermined bit position of each of the delta channels.
