Abstract: ABSTRACT     Four-wing, non-intermeshing rotors are optimized for synchronous rotation to be driven by synchronous drive means at a constant 180° phase angle, there being two long wings and two short wings on each rotor.  A first long wing and first short wing originate at a first end of each rotor, and a second long wing and second short wing originate at the second end of each rotor, the helix angle "A" being the same for all wings on both rotors, and being in the range from about 10° to about 50°.  The axial length 11 is the same for all long wings, the axial length 12 also being the same for all short wings.          Each rotor has a transition zone opening between the termination of a short wing and the termination of the next succeeding long wing relative to the direction of rotation, the next succeeding long wing originating at the opposite end of the rotor from the short wing.  Thus, there are two transition zone openings on each rotor, and all four of the transition zone openings are the same; that is:  Q1=Q2=Q3=Q4   The axial and rotational forces are the same for all the long wings.  Also, the axial and rotational forces are the same for all the short wings.  The axial forces on each rotor advantageously are balanced as well as the rotational and axial forces of both rotors.

Abstract: ABSTRACT OF THE DISCLOSURE      A cartridge for a typewriter typing ribbon comprises a container for accommodating the typing ribbon which can be of correctable or non-correctable type.  A corrector cartridge  can be removably fixed on the lower part of the container by engagement means.  The corrector cartridge  accommodates a correction ribbon which can be of the lift-off type suitable for the typing ribbon of correctable type, or of the cover-up correction type which is suitable for the typing ribbon of non-correctable type.  Coupling means on the cartridge and the corrector cartridge permit the engagement means removably to fix the corrector cartridge to the container only when the cartridge houses the typing ribbon of correctable type and the corrector cartridge houses the correction ribbon of lift-off type or alternatively when the typing ribbon is of non-correctable type and the correction ribbon is of the cover-up type.  In the event of a different choice, the coupling means prevent the engagement means from operating when the ribbons are not compatible with each other.  Fixing means removably fix the container to a support of the typewriter either by itself or with the corrector cartridge attached and the fixing means do not co-operate and interfere with the engagement means and the coupling means.

Abstract: TIME MULTIPLEXED CONTROL OF AIR CORE GAUGES    FROM A MICROPROCESSOR ADDRESS/DATA BUS                  ABSTRACT OF THE DISCLOSURE          An instrumentation system in which air core gauges are adapted for use with a microprocessor that provides data for the gauges in digital form via an address/data bus.  One of the principal features of the invention is that minimum circuitry interfaces the microprocessor with the air core gauges.  Each gauge is assigned to a particular output device on the microprocessor memory map.  The microprocessor addresses a particular gauge via the address bus at the same time that data for the gauge is present on the data bus.  Each gauge comprises a sample and hold circuit and an air core driver circuit which operate the gauge's air core meter.  The sample and hold circuits share a common digital-to-analog (D/A) converter which is interposed between the digital data bus and the sample and hold circuits.  A meter selection logic circuit receives address information from the microprocessor and causes the analog information from the D/A converter to be sampled and held by the particular gauge that is identifed by the particular address being supplied to the meter selection logic.  Each sample and hold circuit holds the information that has been multiplexed to it to thereby provide a continuous output signal to the associated driver circuit which in turn drives the air core meter movement to a corresponding deflection that indicates the value of the data that is in its sample and hold circuit.

Abstract: Methods and apparatus are disclosed for reducing discontinuities between frames of sinusoidally modeled acoustic waveforms, such as speech, which occur when sampling at low frame rates.  A Fast Fourier Transform-based overlap-add technique is applied to amplitude, frequency and phase components of sinusoidal waves after frame-to-frame sine wave matching has been performed.  Matched sine wave amplitudes and frequencies are linearly interpolated and a mid-point phase is estimated such that the mid-frame sine wave is best fit to the most recent half-frame segments of the lagging and leading sine waves.  Synthetic mid-frame sine waves are generated using the interpolated amplitude and frequency and estimated phase values.  Synthesized acoustic waveforms of high quality from original source waveforms can be produced in sinusoidal analysis/synthesis operations at coding frame rates of 50 Hz and lower.  The methods and devices disclosed herein are particularly useful for computationally efficient coding and synthesis of speech waveforms.

Title: Method of forming a thermostatic switch with a narrow operating temperature range
Inventor: GIVLER OMAR
IPC: H01H11/00
Filed: 1989-06-23
Granted: 1994-05-03
Abstract: ABSTRACT OF THE DISCLOSURE The present invention provides a method of forming a thermostatic switch having a calibrated operating temperature range that is defined by a calibrated actuation temperature and a calibrated reset temperature. In accordance with this method a snap action thermostatic switch is provided having a bimetal blade with a snap acting depression.  The blade is formed to have a range of actuation temperatures above the desired actuation temperature and a range of reset temperatures below the desired reset temperature.  The actuation temperature is calibrated in a heated temperature environment that has an initial temperature that is equal to the desired actuation temperature by a fulcrum-like calibration projection.  The reset temperature is then calibrated in the heated temperature environment, after the temperature has been lowered to equal the desired reset temperature.  In a preferred embodiment, this is accomplished by bending a terminal strip mounting the bimetal blade, towards a fixed contact of the switch while the blade is in a deformed state.

Granted: 2001-04-10
Abstract: An apparatus and a method for profiling the intensity of a beam and thus measuring the overall intensity and power of a beam are disclosed that have particular use in stereolithography. A beam sensor comprising a pinhole in a plate and a photodetector behind the pinhole measures the intensity of portions of a beam as the beam is moved over the beam sensor. Software associated with the sensors in a computer controls the scanning mechanism for the beam so that the beam is shifted to find the pinhole and move across it in order to develop the intensity profile. The invention can be used to detect drift in the scanning mechanism, determine the focus of the beam, and predict the depth and width of photopolymer cured by the beam. A related apparatus and method for calibrating and normalizing a stereolithographic apparatus is described, and a related apparatus and method for correcting for drift in production of objects by stereolithography, is also described.
