Title: Means and method for enhancing nucleic acid hybridization
Inventor: HOGAN JAMES J
IPC: C12Q1/6832
Filed: 1988-11-23
Granted: 1996-11-23
Abstract: The binding of a nucleic acid probe with its complementary sequence in a targeted, single stranded nucleic acid is affected by the secondary and tertiary structure of the target nucleic acid. The rate and extent of hybridization of the probe with the targeted nucleic acid can be increased by the use of "helper" oligonucleotides. Helper oligonucleotides are selected to bind to the target nucleic acid and impose a different secondary and tertiary structure on the target to facilitate the binding of the probe to the target. The resulting hybrid of probe and target nucleic acid also exhibits a higher Tm than the hybrid which results from addition of the probe alone.

Title: Paging system employing designated frame commencing information service data message transmission
Inventor: SNOWDEN GREGORY
IPC: H04B7/00
Filed: 1990-10-29
Granted: 1995-10-21
Abstract: A paging system which provides both individual and information services includes a transmitter which transmits page call address and data periodically in batches to subscribing paging receivers. Each batch comprising a synchronization code followed by a predetermined plurality of sequential frames. Each paging receiver searches for both its individual service address and a first information service address in its corresponding assigned frame of each batch of a transmission period, and in response to reception of the first information service address, searches for a second information service address in a designated common frame of each batch of a transmission period. Individual and information service data messages are obtained from frames immediately subsequent the frame in which the respective individual and second information service addresses are found.

Abstract: 건물의 상용 바닥 마감재로서 염화 비닐 타일이나 석재 바닥재등이 사용되었으나 염화비닐 타일류는 천연대리석에 유사한 질감을 나타내는데는 제품으로서 한계가 있었고, 석재류는 가격적인 측면에서 바람직하지 못했다. 
     따라서 본 발명은 이러한 문제점을 해결하기 위해 2종 이상의 반투명 염화 비닐 수지졸을 교반장치를 이용하여 대리석 무늬를 형성하면서 일정두께로 코팅 및 겔링하여 얻어진 대리석 시트층과 염화 비닐 시트층을 합판하여 천연 대리석의 외관을 갖는 바닥장식재를 제조하게 되었다. 
     본 발명에 따른 바닥장식재는 천연 대리석과 유사한 외관과 질감을 나타내며 가격이 저렴하여 상응 건물의 바닥장식재로서 유용하다.

Title: Process for preparing a spherical catalytic component
Inventor: THUM GERHARD DR
IPC: C08F4/60
Filed: 1993-03-26
Granted: 2000-04-15
Abstract: The invention relates to a process for the preparation of a spherical catalyst component based on magnesium chloride for the polymerisation of olefins, which has high stability to mechanical stress during the polymerisation, so that considerable simplifications and advantages are achieved in the handling and processing of the polymeric products produced therewith. This is achieved by coating a specific component with a thin protective layer of polyethylene by prepolymerisation before the actual polymerisation.

Abstract: 본 발명은 전전자 교환기의 패킷처리 시스템에서 타임슬롯 할당에 관한 것으로,서브하이웨이(Subhighway)상에 패킷 데이타를 송신할 경우와 송신하지 않을 경우에 발생하는 타임슬롯 운용의 비효율성을 개선한 패킷 데이타의 시분할 전송방법에 관한 것이다. 본 발명은 타임슬롯의 할당을 동적으로 처리하여 많은 패킷데이타의 전송시 전송시간이 단축되고,전송되지 않는 타임슬롯을 두지 않기 때문에 타임슬롯 운용에 아주 효율적이다.
