Inventor: KUBIS HARALD
IPC: G03B9/06
Filed: 1988-04-26
Abstract: A diaphragm control device for a photographic camera includes a setting member (6) for the diaphragm blades (2) which is caused to move by a spring out of a cocked initial position for different distances corresponding to the diaphragm stops and determined by stepping members (13, 18, 23) which are lockable in sequence in such a way that the basic position of a stepping member kinematically nearer to the setting member (6) is variable by the position of a stepping member more remote from the stepping member (6). The stepping members are electro-magnetically unlockable individually or by groups by the digital outputs of an exposure control circuit. <IMAGE>

Title: Method and arrangement for monitoring the customer passageway at a checkout
Inventor: WANZL RUDOLF
IPC: G07C9/02
Filed: 1988-11-03
Abstract: The invention describes a method and an apparatus (1) for monitoring the customer passageway (7) at a checkout (2) equipped with a payment machine (5) and intended for self-service shops.

Patent DE-3919839-A1 (DE)
Inventor: ESCHER CLAUS DR
IPC: C09K19/42
Filed: 1989-06-17
Abstract: The liquid-crystal element described consists of a housing with transparent discs and electrodes, polarisation foils, orientation films, plus a smectic ferro-electric liquid-crystalline material. This FLC material is dielectrically positive (i.e.  DELTA  epsilon >0), with the result that the liquid-crystal element has a high contrast and, in addition, is switchable even when high voltages (e.g. greater than 15 V) are applied. Unlike LC elements with dielectrically negative material, no change in surface texture occurs under such conditions. The increase in the effective cone angle produced by applying an electric field to the element described above can also be used to produce so-called grey shades.

Patent DE-3942642-A1 (DE)
Inventor: NABI NURAN
IPC: A61K8/31
Filed: 1989-12-22
Abstract: A dentifrice or a liquid mouthwash, containing a substantially water insoluble non-cationic plaque-inhibiting antibacterial agent, such as triclosan, is packaged in a dispensing container or bottle of a solid polymeric material, such as polyfluoroethylene, which is compatible with the antibacterial agent so that loss of anti-plaque agent on storage is avoided. Alternatively, other polymers may be employed as container, which normally would cause excessive losses of anti-plaque agent but such action is countered by the presence of a terpene, e.g. limonene, as a stabilizer in the oral composition.
