Title: Anti-armour spin-stop projectile
Inventor: BONGERS HERMANN DIPL ING
IPC: F42B12/12
Filed: 1988-01-15
Abstract: In the case of spin-stabilised shaped-charge projectiles, in order to eliminate the reduction in the penetration power of the shaped-charge projectile resulting from the influence of the spin, the projectile is formed (pyramids or ogives with toothed ribs fitted to them) such that, when the projectile penetrates into the armour, a toothed system on the projectile engages with the armour and the projectile rotation is stopped. The shaped charge is detonated once the projectile rotation has stopped. In an advantageous refinement of the invention, the shaped charge can be designed as a core projectile (penetrator) and can be mounted in the projectile casing such that it can be displaced axially and can rotate. One or more hard-metal or heavy-metal penetrators can be arranged from the nose of the projectile head in order to increase the penetration performance.

Title: Post/crossmember system for building facades provided with infilling members
Inventor: BROSI MANFRED
IPC: E06B7/14
Filed: 1988-03-16
Abstract: The invention proposes a post/crossmember system for building facades provided with infilling members, which system essentially comprises posts (10) which are to be arranged vertically and parallel to one another and between which crossmembers (11), which open, on the end sides in each case, on the side surfaces of the posts, are to be arranged in an essentially horizontal manner. Abutment and retaining elements (14) for the peripheral sides and front-side border regions of infilling members, e.g. windows, which are to be introduced are arranged in each case on the central region (13, 26) of the front sides of the posts (10) and crossmembers (11). The lateral regions adjoining the central region (13, 26) on either side are configured as abutment surfaces for the rear-side border regions of the infilling members and are provided, at their outer border region (21, 27), with sealing strips (23). The outer border regions (27) of the crossmembers (11) terminate, in the mounted state, on the side surfaces of the posts (10), whereas regions (28), of the crossmembers (11), which are adjacent to these border regions (27) on the inside are arranged in a plane which is offset towards the front and engage over the outer border regions (21) of the posts (10). In this manner, water is reliably prevented from penetrating into the interior of the building, it being possible to use the same sealing strips (23) for the posts and crossmembers, and no milling into the posts, for the purpose of receiving crossmembers, being necessary. <IMAGE>

Title: Complex of at least one lipophilic acid and mitoxantrone and/or bisantrene
Inventor: SCHWENDENER RETO
IPC: C07F9/10
Filed: 1988-07-26
Abstract: The invention relates to a complex of at least one lipophilic acid and mitoxantrone (1,4-dihydroxy(5,8-bis{{2-{2-[(hydroxyethyl)amino]-ethyl}amino}}-9,1-a nthracenedione dihydrochloride (NSC-279836)) and/or bisantrene (9,10-anthracenedicarboxaldehyde bis(4,5-dihydro-1H-imidazole-2-yl)hydrazone dihydrochloride (NSC 337766)), to a composition of a biologically tolerable organic excipient and the previously mentioned complex, and to a remedy containing the complex or the composition. Mitoxantrone has been hitherto administered in the form of an aqueous solution. Administration in the doses necessary for cytostasis, however, causes serious side effects. The cytostatics mitoxantrone and/or bisantrene should therefore be made available in a form which leads to an increased absorption in the intracellular space and thus to an increased activity of the medicaments. A complex of at least one lipophilic acid and mitoxantrone and/or bisantrene as well as a composition of a biological tolerable organic excipient and the previously mentioned complex as well as a remedy which contains the complex and/or the composition are made available. The complex of a lipophilic acid and one of the cytostatics has a substantially increased cytotoxic action in comparison to the free preparation and therefore enables the doses to be administered to be drastically reduced. The complex according to the invention can be employed for the therapy of carcinomas, for example of breast cancer, acute leukaemia and lymphomas.

Title: Method of founding a structure by lowering
Inventor: AICHER MAX DIPL ING
IPC: E02D27/52
Filed: 1989-03-11
Abstract: To found a structure (20) with a continuous base plate (21), it is proposed to make the structure (20) above the foundation horizon (4) and to lower it onto the latter by the in-situ soil under the structure (20) being loosened, conveyed and discharged at the side of the structure (20) into recesses (16) by means of earthworking tools movable in a reciprocating manner under the base surface. The earthworking tools are fastened to a flexible tension means (9) which is movable by means of a drive (24) in a reciprocating manner as well as in a direction at right angles thereto. Thus a structure can be made in a readily accessible manner above its foundation horizon (4) and lowered without impairing the groundwater level by continuous excavation of the soil in thin layers. <IMAGE>
