Inventor: TIAN GANG
IPC: G05B13/00
Filed: 2014-06-24
Abstract: L'invention concerne une bande passante d'unité de commande à stabilisation robuste pour un système mécanique commandé, qui est déterminée en fonction de l'inertie estimée du système et de paramètres de système dominants qui définissent des contraintes sur la bande passante. Dans un ou plusieurs modes de réalisation, un modèle de bande passante est obtenu et définit une relation entre une bande passante d'unité de commande à stabilisation robuste et un gain de système sur une plage d'incertitudes de système raisonnables. À l'aide du modèle, une bande passante d'unité de commande appropriée peut être déterminée pour un système de commande de mouvement donné, étant donné que des estimations du gain de système et du ou des paramètres dominants limitent la bande passante. Dans un exemple de système à deux inerties, le gain de système et le paramètre dominant peuvent comprendre, respectivement, une inertie de système et une rigidité de couplage mécanique. Par conséquent, des estimations de l'inertie de système et de la rigidité de couplage peuvent être fournies au système, qui détermine une bande passante d'unité de commande appropriée pour le système de commande de mouvement caractérisé par les estimations.

Patent CH-673988-A5 (CH)
Inventor: BAIKER WALTER DIPL-ING
IPC: B62D21/18
Filed: 1987-04-29
Abstract: PCT No. PCT/CH88/00082 Sec. 371 Date Dec. 15, 1988 Sec. 102(e) Date Dec. 15, 1988 PCT Filed Apr. 26, 1988 PCT Pub. No. WO88/08384 PCT Pub. Date Nov. 3, 1988.For commercial and special vehicles, such as e.g. weapon transporters, mobile radar stations, mobile satellite control stations and mobile cranes, which must carry very considerable weight, very robust chassis are required. The inventive chassis (1) has a so-called box-frame construction. It comprises a lower and an upper carrier plate (2, 3), which are reinforced and joined by reinforcing elements (12) located between them. This construction leads to an enormous load bearing capacity and extremely high rigidity against twisting or torsion in the case of a reduced height of chassis (1). Unlike the case of conventional chassis constructions with an overall height of 30-40 cm, minimum heights of approximately 10 cm are possible here. Through covering the outer faces of the chassis with vertical cover plates, an additional reinforcement is obtained. These measures permit a configuration which, even when using large wheels, makes it possible to mount the chassis at a very low level. As a result of the inventive chassis, it is possible to use telescopic axle suspensions, such as are described in Swiss patent application 531/87. This makes it possible to adjust the vehicle position even when travelling and without using additional means. In addition, a construction with relatively low weight is obtained.

Patent CH-672833-A5 (CH)
Inventor: SOKOLEAN HELMUTH
IPC: F24F11/76
Filed: 1986-09-30
Abstract: The air conditioning system for rooms is based on regulating the fresh air volume fed to the room and extracting used inside air from the upper air layers of the room. In this process at least approximately fresh air isothermal to that of the room is introduced into the room in a laminar manner from the ceiling region (8). The rate of flow of the fresh air introduced supports the formation of partial flows having dynamic characteristics specific to the room. Preferably the fresh air in the ceiling region is introduced in the vicinity of internal walls of the room facing the facade walls (7). A volume flow regulator (3) is controlled by the temperature measured at the laminar diffuser (6). Preferably a heat exchanger (5) is connected to the fresh air duct (1) in the ceiling region, downstream of which is connected a diffuser (6). The fresh air, which is heated virtually to room temperature in the heat exchanger (5) flows into the room from top to bottom with an essentially laminar flow. The comfort of the air conditioning plant is very distinctly improved by adapting the temperature of the room air by means of the fresh air in the heat exchanger (5) and the introduction of isothermal fresh air into the room at a low speed.

Patent CH-680989-A5 (CH)
Inventor: BUETIKOFER WILLY
IPC: B23Q3/12
Filed: 1983-09-30
Abstract: A tool support, or an extension or reduction part holding a tool support, is held by its shank in an axial bore of a socket of the tool-holding device. The socket has one or more further bores, the longitudinal axes of which each form an angle of from 0 DEG  to about 5 DEG  with a straight line perpendicular to the longitudinal axis of the socket. A setscrew disposed in one such further bore cooperates by means of a beveled or faceted surface at its lower end with a chucking surface running on the outside of the shank at an angle to the longitudinal axis thereof. Another setscrew may cooperate with a second such chucking surface forming an angle of about 45 DEG  with the first chucking surface. Faultless force-locking and a bias are produced between the end faces of the socket and of the tool support, thus making it possible to combine even large, heavy boring tools with universally usable tool-holding devices inasmuch as there is sufficient resistance to torsional stress between the tool-holding device and the tool support.

Title: Process for producing mineral fibre slabs, device for carrying out the process, mineral fibre slab produced by the process and use thereof
Inventor: WYSS PETER
IPC: C04B14/38
Filed: 1977-06-08
Abstract: In the process a layer of mineral fibres (11) wetted with a binder is carried from a first conveying device (13) via a pre-press (19) to a more slowly running conveying device (17) in a through-type oven (35). During the conveying upstream of and in the through-type oven, the mineral fibre layer is compressed in its length and thickness. The fact that the mineral fibre layer, when entering the through-type oven (35), bulges out in alternate directions and is then compressed in its thickness means that mineral fibre slabs having flat surfaces and high compressive strength and tear strength transversely to the slab plane are produced. The mineral fibre slab is suitable in particular as roofing slab for insulating house roofs. <IMAGE>
