Patent DE-4008790-A1 (DE)
Inventor: PEITZ ALBERT
IPC: H04L12/20
Filed: 1990-03-19
Abstract: Circuit arrangement for telecommunication switching networks preferably telephone switching networks, consisting of exchanges, in which mobile subscribers (MT1-MT9) each have access to an exchange (SC) through radio channels (F1-F9) and stationary subscribers (STa-STo) each have access to an exchange (SC) through cable channels (K1, K2), an individual identification being assigned to each mobile subscriber. Both the mobile and the stationary subscribers (MT1-MT9; STa-STo) are each assigned an individual identification with which the subscriber answers (identification signal) and is thereby identified and localized by the exchange (SC). The exchange (SC) then assigns a pair of communication channels to the subscriber (MT1-MT9) to establish a connection between the subscriber and the exchange (SC) or vice versa. The mobile and stationary subscribers have access to the same exchanges (SC) and the accesses of the stationary subscribers (STa-STo) pass through broad-band cables (K1, K2), preferably glass fibre cables, which run directly to the subscribers. The cables extend over the entire distance between the exchanges (SC) and the stationary subscribers without intermediate sub-exchanges and individual wire connections, and the same signalization (identification signal), channel allocation (pair of communication channels) and news transmission as between the exchange (SC) and the mobile subscribers (MT1-MT9) connected to it is carried out through the cables so that each subscriber, whether mobile or stationary, is reached from each exchange (SC) in the same manner through a through pair of continuous communication channels. To reach all subscribers, the number of pairs of communication channels provided is no greater than that necessary for the expected volume of traffic in the corresponding region.
Patent DE-4009912-A1 (DE)
IPC: G08B13/196
Filed: 1990-03-28
Abstract: Infrared light barriers or video control systems are used, as is known, in monitoring bounded, plane areas, for example a level crossing. However, both solutions have the disadvantage that they are unreliable or are of a very complicated design. The invention provides a video control system which permits reliable evaluation using simple means. For this purpose, a camera is used to take and store two fields in each case, one being taken without flash, and the other with. A differential image, now containing only signal components caused by the light of the flash is obtained from the two fields. Given the presence of a three-dimensional object in the monitored area, there is produced on the side of the object averted from the flash a shadow signal which is evaluated and, if necessary, fed to the alarm-triggering device. <IMAGE>

Title: Surgical clip application pincers - are made of sterilisable material and has tube between claws and grip halves
Inventor: LAZIC PETER
IPC: A61B17/128
Filed: 1990-08-03
Abstract: The tube is connected to one of the grip halves (4, 5), and holds the claws (9, 10) movably at its other end. It forms a hose-type covering (2) which is flexible, and can be  composed of a spring steel wire wound around a claw operating cable (7). When the cable is operated the tube remains stable.

Patent DE-4026444-A1 (DE)
Title: Variable low-pressure sequential-return force cap lift
Inventor: SMITH RODNEY P
IPC: B65D83/34
Filed: 1990-08-21
Abstract: The head has a lower bell which forms a seal with the upper end of the container when the head is lowered. While the bell remains stationary, other parts of the head are actuated so that vacuum is applied to the bell and the container while closure is lifted by vacuum from the mouth.  Afterwards, the head is actuated to shut off the vacuum and admit a metered quantity of fluid under pressure, such as aerosol propellant, into the bell and container.  when the pressurised fluid is admitted it lifts the closure from the container mouth and also acts to lift as a unit all parts of the head except the bell which remains stationary and engaged with the container. The combined weight of the lifted part augmented by a first hydraulic or pneumatic hold-down force resist the lifting action. After the desired quantity of propellant has been introduced, a second hold-down force is applied which in combination with the previously applied weight of the lifted parts and first hold-down force restores the lifted parts to their normal or lowered position.  The collet in the head is actuated to crimp the closure to the mouth of the container.
