said beams on a detector, said detector having a 
vertically extending axis representing the path of 
the vehicle to the target, said beams being focused 
on said detector at two spaced-apart points on 
opposite sides of the vertically extending axis 
wherein a difference in distance from the vertical 
axis of the detector of said two spaced-apart 
points represents a deviation from the proper path 
of the vehicle to said target and an equality of 
distance of two said spaced-apart points to said 
 
 
vertically extending axis represents the proper 
path to the target,

Patent EP-0335265-A3 (EP)
IPC: A23L27/30
Filed: 1989-03-23
Abstract: It is known to use parts of Stevia rebaudiana plants or extracts or isolates obtained therefrom and enzymatic transformation products as sweeteners. The introduction of these sweeteners is prevented in European and American cultural circles by an extraneous taste or aftertaste which is not sweet. All purification processes which have been developed to date and can be carried out on the industrial scale give products retaining this upsetting taste. It is possible according to the invention to remove the concomitant substances which have an upsetting taste from parts of the plant or known extracts and the further processing products thereof by extraction with a supercritical gas, carbon dioxide being the preferred extractant for practical reasons. Preparation of sweeteners for foodstuffs and beverages on a natural basis.

Abstract: A boat hull or part thereof is produced by applying 
layers of curable resin to a mould or former and curing the 
resin in the mould or on the former. A layer of a non-­
biocidal antifouling material is applied to the mould, or 
to the outermost layer of resin if using a former, so that 
the non-biocidal antifouling material forms the outermost 
layer of the boat hull. A non-biocidal antifouling 
material used as the outermost underwater surface of a boat 
hull has fine grooves extending in the longitudinal direc­

Title: Multivalent repressor of gene function
IPC: C12N15/49
Filed: 1990-05-23
Abstract: Transdominant repressors of viral gene phenotypic expression derived from the rev gene product of HIV-1 or the rex gene product of HTLV-1 and corresponding mutated genes are described', having the capability of repressing the Rev function in HIV-1 and/or the Rex function in HTLV-I and HTLV-II. Transient gene expression analysis of a series of missense and deletion mutants has been used. Some of the mutants found repress both the Rev and the Rex function and are thus active in more than one viral species. Transdominant viral mutants represent a promising new class of anti-viral agents. Cellular expression of these transdominant inhibitors may be used in such therapeutic approaches as intracellular immunization in order to protect cells against the deleterious effects of viral, e.g. HIV-1 infection.
