Title: Hypodermic syringe
Inventor: LUCAS DIETER
IPC: A61M5/20
Filed: 1990-08-20
Abstract: In a hypodermic syringe (10) with a hypodermic needle (20) which is adapted to be extended from a needle space (19) from a readiness position into an operative position by a force storage means (28), the invention seeks to make it possible to render the hypodermic needle (20) inaccessible after use.

Patent CA-2026809-A1 (CA)
Title: Haloperoxidase acid optimum chemiluminescence assay system
Inventor: ALLEN ROBERT C
IPC: C12Q1/28
Filed: 1990-10-03
Abstract: A highly sensitive chemiluminescent indicator system is disclosed for determining the presence or amount of an analyte in a liquid sample. The new acid optimum chemiluminescent indicator system comprises haloperoxidase (halide:hydrogen peroxide oxidoreductase), halide, oxidant and chemiluminigenic substrate. The indicator system acts as a synthesizer of highly reactive singlet molecular oxygen (1O2), which reacts with the chemiluminigenic substrate to yield an excited state, oxidized reaction product. The excited state reaction product then relaxes to a lower energy (e.g., ground) state with the emission of measurable light in an amount related to the amount of each of the reaction participants present in a reaction solution. Known, non-rate limiting amounts of three of the reaction participants are provided in an assay solution to determine the presence or amount of the fourth participant in a test sample. The fourth participant in the test sample may be the analyte of interest, or may be produced or consumed in the test sample through one or more preliminary reactions involving the ultimate analyte of interest, with the amount of the fourth participant being related to the amount of analyte in the test solution. Accordingly, the indicator system of the invention may be employed for the determination of a wide variety of analytes.     The indicator system operates most efficiently over the range from acid to slightly basic pH, e.g., at a pH of about 3 to about 8. Also described is a variety of illustrative assay formats in which the indicator reaction of the invention may be employed, as well as kits for use in carrying out assays utilizing the haloperoxidase/halide/oxidant/substrate indicator system.

Title: Electric drive for a rectifying segmented transducer
Inventor: CULP GORDON W
IPC: H01L41/04
Filed: 1992-10-23
Abstract: ABSTRACT      The continuous bipolar mechanical output of a nonrectifying transducer is synthesized when the electrical segments 2 of a rectifying transducer are alternately switched into and out of a resonant loop in synchronism with polarity changes of the alternating drive signal. The known extraordinary transduction efficacy of a diverse class of rectifying transducer materials is thereby advantageously applied, while the known high electrical efficiency of resonance is also applied.          Continuous bipolar transduction provides essential ingredients for the synthesis of nonsinusoidal mechanical output waveforms that afford extraordinary mechanical efficiency in a growing class of mechanical actuators, such as forcers, positioners and rubless walkers. Electrical resonance, in combination with nonsinusoidal mechanical waveforms, therefore provide a segmented rectifying transducer drive system of extraordinary efficacy.
