Abstract: RD-20,425 ABRASION METHOD OF FORMING FILAMENT REINFORCED COMPOSITES                 ABSTRACT OF THE INVENTION         A method for forming a reinforced metal structure having a filamentary reinforcement evenly distributed therein is taught.  The structure is formed by the plasma spray deposit of matrix metal onto and about a filamentary reinforcement.  A plurality of layers of filamentary reinforcement are embedded in the structure.  Between each layer an abrasive grinding and smoothing operation is performed to render the surface of the spray deposited metal smooth and even and to permit the even spacing of filament reinforcement on the spray deposited surface.  The abrasive grinding of the spray formed surface does not have deleterious effects on the property of the composite reinforced structure which is formed.

Filed: 1991-08-26
Abstract: ABSTRACT         A compensated amplitude comparison monopulse receiver (10) having an angular measurement capability substantially unaffected by mismatches in channel transient response and target range tracking inaccuracy is disclosed herein.  The inventive monopulse receiver (10)  includes a first receiver channel  (24)  for impressing a first output voltage S1 on a first output port (28) thereof in response to excitation by a sum signal.  A second receiver channel (26)   impresses a second output voltage S2 on a second output port (30) thereof in response to excitation by the sum and a difference signal.  In a calibration mode, a calibration source (22) provides a series of calibration pulses to the first and second channels (24, 26) which induces first and second calibration voltages to appear on the first and second output ports (28, 30) thereof.  Sampling gates (32, 34) sample the first and second calibration voltages subsequent to application of each calibration pulse to the first and second receiver channels (24, 26). In a tracking mode the sample gates (32,  34)  are operative to sample the first and second output voltages i present on the first and second output ports (28, 30). The inventive receiver 10 further includes circuitry (48, 50) for calculating the angular location of the first object from the sampled first and second output voltages. A compensation network (36) then adjusts the calculated angular location on the basis of the sampled calibration voltages.

Title: Device for measuring the time which a removable medical device has been in place
Inventor: KUMMEL DIETMAR
IPC: G04F10/04
Filed: 1990-07-13
Abstract: ABSTRACT            Wearing time measuring device for a removable medical apparatus A medical apparatus to be worn in the mouth comprises a battery-fed measuring unit (15) including a clock gen-erator (18) and a counter (20) for counting the pulses of the clock generator. Accuracy of the time measure-ment decisively depends on the precision of the oscil-lating frequency of the clock generator. In the inven-tion,  there is used a clock generator (18)  wherein frequency precision is low. When the counted value of the counter (20) is read into an external evaluating unit, the measuring unit supplies a reference time re-quired by the clock generator  (18)  for generating a number of pulses. The evaluating unit calculates the time corresponding to the counted value under consid-eration of the length of the reference time. Thus, the evaluating unit measures the cycle length of the pulses of the clock generator, and this cycle length is multi-plied by the number of the counted clock pulses.  In this manner, time measurement is performed in a precise manner without requiring a highly precise clock gener-ator.            (Fig. 2)
