Filed: 1988-01-04
Abstract: The one-piece snap closure made of plastic for the opening of a container is provided with a sealing lever (3) above a covering plate provided with an opening, which sealing lever is articulated to a spring hinge (2) which is connected to the upper side of the closure in an articulated manner via a swivel connection (16). The sealing lever (3) and the spring hinge (2) are of approximately rectangular construction and, in the closed position, fill a diametrical incision in the upper side of the closure together with guide cylinders (7) of the swivel connections of the spring hinge (2) in such a way that the upper side of the sealing lever (3) and of the spring hinge are in alignment with the upper side of the closure. The upper side of the closure extends tangentially above two guide cylinders (7) of the sealing lever (3) which are connected eccentrically along a line (17) of the outer surface to the swivel connection (15) between the sealing lever (3) and the spring hinge (2) and engage in insertion openings, which are open upwards, in support walls on the covering plate. In the swivel direction (8), the sealing lever (3) reaches the open position (10) only after overcoming a dead centre position (9), up to which point the spring hinge (2) curves in the direction (x) until it subsequently assumes an unstressed position below the upper side (at 23a). A sturdy closure is thus provided which does not project beyond the closure edge after being opened and completely covers the mechanism so that the function of the spring hinge is not or is hardly recognisable.

Title: Method for producing recombinant protein derived from the circumsporozoite gene of plasmodium falciparum
IPC: C12N15/866
Filed: 1989-02-17
Abstract: The baculovirus-insect cell vector system is useful 
as a high efficiency eukaryotic cloning and expression 
method for the production of the recombinant proteins. A 
major application of this system is in the development 
of rDNA vaccines for important human and animal diseas­
es. This system is also useful to express the circum­
sporozoite antigen of a parasite that causes malaria in 
humans,  Plasmodium falciparum . The resulting recombi­
nant protein consists of full-length circumsporozoite 
antigen. The results indicate high levels of expression 
into recombinant products which closely resemble the 
authentic product. Furthermore, it has been demonstrat­
ed to effect purification of the recombinant product to 
near homogeneity. The expression of this gene by the 
baculorvirus-insect cell vector system yields these 
desirable results because this gene is normally ex­
pressed by insects. Recombinant circumsporozoite pro­
teins produced in this manner have application as ingre­
dients for sub-unit vaccines to protect against malaria, 
and as an ingredient for malaria diagnosis.

Title: Space management system incorporating a software-operating environment
IPC: G06F9/44
Filed: 1989-10-20
Abstract: A space management system comprises a space management 
applications program, possibly executing concurrently with 
other applications programs, and an Operating Environment. 
The applications program comprises support files (including a 
structure file) and a functions file. An Operating 
Environment at a level of software between the operating 
system level and the applications program level controls a 
user's interface with one or more concurrently executing 
applications program. By forming a common data structure, the 
Operating Environment allows functions within the various 
applications programs to execute independently of the nature 
of the particular user interface. The common data structure, 
part of an aggregate applications program, arranges data so as 
to be concurrently accessible to the functions originating in 
the various applications programs. Conversely, the user 
interface remains substantially of the same character, 
regardless of the particular nature of the applications 
programs. Independence of the applications programs from 
particular input and output devices and batch data devices and 
formats is also enabled. High-level Batch Data System 
software modules are flexibly interconnectible with low-level, 
device-specific, format-specific modules. The flexible 
interconnectibility shields the user from the specifics of 
data storage formats, and easily accomodates new formats 
without changing high-level software.
