Title: Exterior wall element for buildings
Inventor: SCHULZ HARALD
IPC: E04C2/54
Filed: 1995-11-04
Abstract: An outer wall element for buildings has an outer, solar radiation-permeable heat-insulating layer (5) arranged between an inner shell (1) and an outer, solar radiation-permeable shell (2). This heat-insulating layer (5) is adjacent to the outer shell (2) and is separated from an inner heat-insulating layer (3) that belongs to the inner shell (2) by an interface (6) that absorbs the solar radiation from the outer heat-insulating layer (5). At least the inner shell (1) is provided with marginal lining elements (8) that extend at least up to the interface (6) and convey heat to the inner side of the wall. The lining elements may be part of a frame, a metallic panel or the like. In order to protect the lining elements (8) from the high temperatures that result from the use of solar energy in the outer heat-insulating layer (5), the outer heat-insulating layer (5) and the lining elements (8) are mutually separated by poor heat-conductive insulating parts (12) that starting from the lining elements (8) cover the inner heat-insulating layer (3) along a marginal strip (13) located in the interface (6).

Title: Glycoprotein b of the rfhv/kshv subfamily of herpes viruses
Inventor: BOSCH MARNIX L
IPC: C12P21/08
Filed: 1996-09-26
Abstract: This invention relates to polynuclelotides encoding Glycoprotein B from the RFHV/KSHV subfamily of gamma herpes viruses, three members of which are characterized in detail. DNA extracts were obtained from Macaque nemestrina and Macaque mulatta monkeys affected with retroperitoneal fibromatosis (RF), and human AIDS patients affected with Kaposi's sarcoma (KS). The extracts were amplified using consensus-degenerate oligonucleotide probes designed from known protein and DNA sequences of gamma herpes viruses. The nucleotide sequences of a 319 base pair fragment are about 76 % identical between RFHV1 and KSHV, and about 60-63 % identical with the closest related gamma herpes viruses outside the RFHV/KSHV subfamily. Protein sequences encoded within these fragments are about 91 % identical between RFHV1 and KSHV, and < 65 % identical to that of other gamma herpes viruses. The full-length KSHV Glycoprotein B sequence comprises a transmembrane domain near the N-terminus, and a plurality of potentially antigenic sites in the extracellular domain. Materials and methods are provided to characterize Glycoprotein B encoding regions of members of the RFHV/KSHV subfamily, including but not limited to RFHV1, RFHV2, and KSHV Peptides, polynucleotides, and antibodies of this invention can be used for diagnosing infection, and for eliciting an immune response against Glycoprotein B.

Abstract: A telecommunications system (100) includes a service provider (200) providing a plurality of services to a plurality of terminals (400, 401, 402). A  controller (300) having a user identifier stored therein can be associated with a reader in the terminal for reading the user identifier. A selector in the terminal (400) selects one or more of the plurality of services to be associated with the user identifier. A transmitter transmits to the service provider (200) user-service information corresponding to the user identifier and information as to the selected services. The service provider (200) receives the user-service information and determines from which service provision area the user-service information was transmitted. A service provision controller determines that a particular service is to be provided to the user and a determining means determines whether the particular service is included in the first set of selected services. A paging message having paging information corresponding to the user-service information is then transmitted to the service provision area. The terminal (400) receives that paging message and responds to the service provider (200) if it can accept the service.

Abstract: An electrical sleeve heater has a tubular outer wall and a heating coil inside the outer wall.  An outer sleeve inside the heating coil formed with an axially throughgoing slot having angularly confronting edges is made of a material having a high coefficient of thermal expansion.  An inner sleeve inside the outer sleeve is formed with an axially throughgoing slot and with outwardly projecting lips engaged through the outer-sleeve slot bearing angularly on the outer-sleeve slot edges.  It is made of a material having a low coefficient of thermal expansion so that when the sleeves are heated the outer-sleeve edges press the inner-sleeve lips together and thereby decrease the radial inner diameter of the inner sleeve.
