Abstract: A cutting and mowing apparatus comprising a continuous sickle chain assembly (8) utilizing cutting knives (10). The sickle chain assembly is confined within channel (29) formed by stationary guards (28) by means of alternating chain members (12), knives (10), and links (14). The sickle chain assembly is motivated by drive assemblies (31), which possess an integral protective slip clutch assembly (45). The sickle chain assemblies tightness is maintained using spring loaded tensioner assemblies (89). On the rearward return path, the sickle chain assembly slides in the return channel (144). The drive assemblies (31) are powered from the hydraulic system of the parent machine, such as a combine, tractor, or mower/conditioner. This unit, while being designed to retrofit existing cutting machines, can also be used for new production models.
Abstract: A control system, method and apparatus are provided in which a rotatable wedge portion which is solidly mounted on a rotatable base engages piston and cylinder assemblies as the base rotates. The wedge is rotatable through various positions relative to the base, thus providing an adjustable tilt angle and different strokes for the pistons. In another embodiment, the single wedge is replaced by a double wedge assembly.
Abstract: A fractional-power electric motor is provided to generate varying amounts of output torque supplied to a driven member over a wide range of RPM speeds so as to reduce power consumption on a battery-powered source. The electric motor includes a rotor and a stator assembly. The stator assembly is disposed around the rotor and is inductively coupled to the rotor. The stator assembly further includes a plurality of poles, each having a main winding and at least one fractional-power winding. The main winding and associated at least one fractional-power winding on each of the stator poles are wound so that the magnetic fluxes generated therefrom are added. Power switching circuits are provided for independently energizing the main and fractional-power windings on each of the stator poles. A controller is used to control selectively the frequency and duty cycle energization of the power switching circuits to vary the rotational speed of the rotor and the amounts of torque supplied to the driven member.
Abstract: An adjustable rotor and/or a radial piston machine which may utilize an adjustable rotor.

Abstract: The present invention relates to a thruster for propelling a mass using a propellant gas which is repetitively converted to a pressurized plasma by pulses of electrical energy.
Abstract: A digital phase lock detector for determining the periods of an incoming signal for use in measuring rapidly and accurately the relative speed or velocity of vehicles according to the Doppler-radar principle includes a micro-controller based processor unit operated under a stored program to perform period determination. A bandpass filter is provided for generating a periodic signal which has a frequency which is varied in accordance with the velocity of the target vehicle in response to a difference Doppler signal. A comparator is responsive to the periodic signal for generating a rectangular pulse signal which is a digital representation of the periodic signal. The processor unit includes a microprocessor for determining the period of the pulse signal by integrating a number of consecutive cycles to produce a synthesized Doppler frequency signal having a frequency which is proportional to the velocity of the target vehicle.

Abstract: A method and apparatus for producing nanodrops which are liquid drops with diameters less than one micron and producing therefrom solid nanoparticles and uniform and patterned film deposits. A liquid precursor is placed in an open ended tube within which is a solid electrically conductive needle which protrudes beyond the open end of the tube. Surface tension of the liquid at the tube end prevents the liquid from flowing from the tube. Mutually repulsive electric charges are injected into the liquid through the needle, causing the surface tension to be overcome to produce a plurality of liquid jets which break up into nanodrops.

Abstract: A corn head with a pair of parallel counterrotating harvesting rolls is disclosed. Each roll has primary flutes and secondary flutes extending longitudinally which oppose flutes of the other type on the other roll. Improved ear stripping and stalk processing by crushing result.
Abstract: A garment for use by a patient after surgery for breast removal which alleviates post-operative pain and discomfort and facilitates normal activities during the recovery period. A padded vest-like garment is adapted for applying comforting pressure to the sites of removal of breast and other tissues and for holding pain relieving packages. A detachable arm support provides further comfort in a similar manner.
Abstract: An intelligent interface arrangement is provided for controlling and sensing operation of one or more random access slide projectors from a host computer or intelligent terminal. The interface arrangement includes a first microprocessor controlled communication section and a second microprocessor controlled receiver section. One of the receiver sections is provided for each slide projector to be controlled. The communication section bidirectionally communicates with the host over a first communication interface and bidirectionally communicates with the receiver section over a second communication bus structure. The receiver section communicates with the controlled slide projector over a control bus including predetermined signal points in the slide projector and keyboard control lines.

Abstract: Random access slide projector apparatus is provided for the random access presentation of slide programs. The random access apparatus is responsive to an encoded program tape or to input signals from a local or remote keyboard. The encoded program tape includes predetermined slide address signals as burst format signals corresponding to desired slide positions in the slide tray. The random access apparatus decodes the encoded slide address signals and generates appropriate control outputs to move the slide tray to the desired programmed slide position and project the desired slides. The random access apparatus also provides for the recording of slide address signals in accordance with keyboard entries to prepare random access program tapes. The program tape includes one track for the recording of encoded slide address signals and a second synchronized track for narrative program information to accompany the slide program.
