Title: Method of distinguishing nucleic acids on the basis of nucleotidic difference between them
IPC: C12Q1/68
Filed: 1991-02-12
Abstract: A process is provided for detecting polymorphisms on the basis of nucleotide differences in random segments of the nucleic acid by performing a primer extension reaction on the nucleic acids and comparing the extension reaction products. The random nucleic acid segment can be amplified by first dissociating the extension product from the template and contacting the dissociated extension product with a primer under conditions such that an amplification extension product is synthesized using the dissociated extension product as a template. Differences in the extension product are useful as markers in constructing genetic maps and as markers to distinguish or identify individuals.

Title: Medical valve with a space for collecting escaping fluids
Inventor: LOPEZ GEORGE A
IPC: A61M39/10
Filed: 1996-12-16
Abstract: A medical valve has a body which includes a wall structure defining an internal cavity having an inside and an outside. The body also has a proximal end and a distal end. The proximal end has an opening sufficiently large to receive a tip of a delivery end of a medical implement which transfers fluid through the delivery end. The body has a fluid escape space in its wall structure. The valve also has a spike with a tip and at least one hole located at or near the tip. The spike has a passageway in communication with the hole that allows fluid to flow through the spike. A resilient seal in the cavity surrounds the spike. This seal is adapted to be moved into a compressed state upon insertion of the tip of the medical implement into the opening. The seal is sufficiently resilient to return to a decompressed state upon removal of the tip of the medical implement from the opening. The fluid escape space is in fluid communication with the outside of the cavity when the seal is in its compressed state.

Title: Structurally supported resilient tire with bias ply carcass
Inventor: THOMPSON RONALD HOBART
IPC: B60C9/07
Filed: 2001-04-16
Abstract: A resilient tire (100) that supports a load without internal air pressure includes a ground contacting tread portion (110) and sidewall portions (150) extending radially inward from said tread portion and anchored in bead portions (160) adapted to remain secure to a wheel (10) during rolling of the tire.

Abstract: Przedmiotem wynalazku jest sprężarkowa pompa ciepła z akceleratorem termicznym, gdzie czynnikiem roboczym jest gaz propan- butan, który w temperaturze dolnego źródła, wynoszącej 5°C, ma prężność par na poziomie 4 barów. W obiegu czynnika roboczego, pomiędzy parownikiem (1), a sprężarką (10), umiejscowione jest urządzenie Vortex Tube (4). Czynnik roboczy w fazie ciekłej w parowniku (1) pobiera ciepło z dolnego źródła, paruje, co powoduje podniesienie ciśnienia w parowniku (1) do poziomu 4 barów. Czynnik roboczy w fazie gazowej o temperaturze 5°C i ciśnieniu 4 barów trafia za pośrednictwem zaworu regulacyjnego (2) do wejścia (3) urządzenia Vortex Tube (4), gdzie jest rozdzielany na dwa strumienie o niskim ciśnieniu, ciepły (5) o temperaturze 62°C i zimny (6) o temperaturze -35°C (stosunek objętości strumienia ciepłego do zimnego wynosi 4/6). Strumień zimny (6), poprzez zawór regulacyjny (7) i za pośrednictwem wymiennika ciepła (8) jest ocieplany do temperatury 5°C (korzystając z energii dolnego źródła), a następnie mieszany (9) ze strumieniem ciepłym (5), co w konsekwencji daje strumień czynnika roboczego trafiającego do sprężarki (10) o temperaturze 22°C. W kolejnym etapie czynnik roboczy trafia do skraplacza (11), gdzie jest skraplany i oddaje ciepło, a następnie, już w fazie ciekłej, poprzez zawór ekspansywny (12) trafia do parownika (1).
