Abstract: A device for aligning a disk contained in a cartridge with a motor and transducer of a disk drive is disclosed.  A record disk contained within a rigid apertured cartridge is inserted into a disk drive for use with that disk drive.          Insertion of the cartridge into the disk drive causes engagement of a reference surface of the cartridge with a reference surface of a spicule member contained within the disk drive.  The spicule member carries the transducer and drive spindle of the disk drive.  The spicule member also contains a clamping device which ensures proper engagement of the cartridge reference surface and the spicule reference surface.          The result is the proper alignment between the disk contained in the rigid cartridge and the transducer and motor spindle carried by the spicule member.

Title: Pharmaceutical preparations containing iodine having a low water content
Inventor: RACKUR HELMUT
IPC: A61K33/18
Filed: 1988-03-31
Granted: 1993-07-20
Abstract: A b s t r a c t Known pharmaceutical preparations with iodine content in an (organic) solvent have high water contents.          They cannot be stored for long times and often produce high local iodine concentrations in the application area, which result in skin irritations.          They delay the operation due to their relatively slow evaporation, which is further uncomfortable for the patient due to the cooling effect. It is an object of the invention to overcome these disadvantages. The preparation according to the invention has only very small water content or is even completely non-aqueous. The preparation is storable for several years and evaporates very quickly on application without producing any excess local iodine concentrations. Unexpectedly, the non-aqueous preparation is thoroughly microbicidal in the 10-seconds range and further also kills spores quickly and with high efficiency.

Title: On/off control circuitry for television
Inventor: STANLEY ROBERT L II
IPC: H04N5/63
Filed: 1988-04-21
Granted: 1991-09-10
Abstract: Abstract A control circuit of a television receiver power supply is constructed using a plurality of transistors operating in a common base configuration. The base electrodes of each of the transistors is coupled to a common conductor that maintains the collector currents in the transistors temperature compensated over a wide range of operating temperatures during normal operation power-up mode of the receiver.  In a standby mode of the receiver, power dissipation in the transistors is reduced by applying an on/off control signal to the common conductor that prevents the flow of the collector currents in each of the transistors.  Consequently, the supply current requirement of the control circuit is reduced during the standby mode.

Cependant, les phases A, B et C de la troisième tension sont déphasées par rapport aux phases B, C et A de la quatrième tension d'un angle de 90.degree.. Les impédances réactives variables établissent entre chaque phase des première et seconde tensions et deux phases des troisième et quatrième tensions qui sont déphasées de 90.degree. deux liaisons de susceptances variables, respectivement. Les impédances sont manoeuvrées en fonction de paramètres reliés au fonctionnement des deux réseaux pour varier les susceptances des liaisons de sorte à établir un transfert désiré de puissance active, tout en maintenant la puissance réactives à un niveau désiré.
