| 4939527 | Distribution network for phased array antennas A distribution network for a modified space-fed phased array antenna consists of a planar array of radiating slots distributed along a coplanar wall in each of an ensemble of parallel waveguides. This waveguide ensemble is fed or excited by an orthogonal ... | 07/03/1990 |
| 4918409 | Ferrite device with superconducting magnet A ferrite device has a closed superconductor which encircles a ferrite element. The closed superconductor continuously circulates a current to produce a magnetic field for biasing the ferrite element.... | 04/17/1990 |
| 4908510 | Optical fiber coupled resolver having a reference signal An optical encoder produces a reference signal and compensates for any instability in intensity of a light source which reads the encoder. The optical encoder comprises a movable encoding element having an analog track of variable transmissivity, and a ch... | 03/13/1990 |
| 4898089 | Laminar flow work table with controllable ventilation of a work surface A laminar flow work table has a perforated work surface positioned and supported a predetermined distance above a floor surface. The perforated work surface is divided into sections. Each section communicates with a separate duct communicating with the pe... | 02/06/1990 |
| 4892376 | Optical backplane for circuit boards An optical backplane comprises a light source that transmits a light beam through apertures of aligned circuit cards. An optical modulator on each circuit card writes information onto the light beam. An optical demodulator on each circuit card reads infor... | 01/09/1990 |
| 4870426 | Dual band antenna element A radar antenna element comprises a lower band waveguide and an array of parallel, dual-polarized, higher band waveguides and dipoles mounted within or directly adjacent an aperture of the lower band waveguide. The lower band waveguide and each higher ban... | 09/26/1989 |
| 4861797 | Liquid ibuprofen compositions and methods of making them A clear, stable, and palatable liquid ibuprofen composition has ibuprofen, or a pharmaceutically acceptable salt or ester of ibuprofen, in an aqueous medium containing a methylcellulose composition. A process of making such an ibuprofen composition is sig... | 08/29/1989 |
| 4858616 | Blood pressure measurement system for filtering low-frequency, high-amplitude noise A noise-immune blood pressure measurement system filters out high frequency noise and blood pulses. The system also recognizes and filters out slow, large noise signals in the range of 0.5 Hz. Such noise signals result when a patient wearing the system ma... | 08/22/1989 |
| 4859704 | Water soluble ibuprofen compositions and methods of making them A novel water soluble alkali metal salt of ibuprofen is prepared by reacting ibuprofen and an alkali metal bicarbonate in a aqueous medium. The salt is useful in treating pain, inflammation, and fever in mammals. It permits the preparation of a number of ... | 08/22/1989 |
| 4825618 | Overlapping tile Tiles 60 inches long fit on a wall along the length of a standard bathtub, and when cut in half, fit on walls at ends of a standard bathtub. Each tile has a lip and flange that overlap adjacent tiles in a way that makes grouting unnecessay between adjacen... | 05/02/1989 |
| 4797518 | Braking indicator A fluid responsive switching mechanism is located on a brake actuator in a vehicle to signal impending brake actuation as quickly as possible to reduce the risk of accidents such as rear end collisions. Direct contact with the brake actuator by the driver... | 01/10/1989 |
| 4782904 | Electronic balance A microcomputerized electronic balance has a digital filter which filters the output of a weight transducer in the balance. The filter changes the amount of filtering in response to the resolution of a display in the balance, the desires of the user of th... | 11/08/1988 |
| 4769121 | Sintered pellet with biochemically active layer A sintered powder electrode has a biochemically active layer embedded in pores of the electrode.
