Patent DE-3737511-A1 (DE)
Title: Triggered gripper trap, in particular musk-rat gripper trap, with an automatically engaging securing means, when the trap is set, and an automatically engaging release mechanism
Inventor: LEPRICH DIRK
IPC: A01M23/26
Filed: 1987-11-05
Abstract: The triggered gripper trap is used for combating musk-rats. It is used on terrain on which it is difficult to walk. The minimal weight necessary therefor is fulfilled by low outlay in terms of materials and individual parts. An environmental awareness which is important to us requires traps which trap the musk-rat securely and exclude the trapping of birds. This requirement is also fulfilled by the described trap in that a particularly uncomplicated, simple and unique release mechanism has been developed, which, when using bait for trapping, is only released when the pulling, feeding release movement, such as that effected by the musk-rat or the like, takes place. Since traps of this generic type permit metal frames to move together in a gripping manner, there are also dangers for the users. These are prevented, however, since the traps are immediately automatically secured during setting. The handling, which is necessary for setting traps, as is the case with other traps, with complex mechanisms is dispensed with. This trap is designed such that it is suitable only for trapping by bait. All traps which are suitable for various methods of trapping are not safe for birds because every passing animal can come into contact with the trap, thus releasing it.
Patent DE-3743582-A1 (DE)
Title: Single-ball lifting-out and row-grubbing appliance
Inventor: HEITZLER KARL
IPC: A01G23/04
Filed: 1987-11-30
Abstract: The invention relates to an appliance for separating and releasing the root system of plants in tree nurseries. So-called vibrating ploughs are known for this purpose. In these appliances, a grubbing cutter is set in oscillating movement and is drawn through under the root system. A disadvantage of these appliances is that only continuous rows of plants can be worked. The design according to the invention of a single-ball lifting-out and row-grubbing appliance now makes it possible to lift out the root balls of individual plants from the plant row, without cutting under the roots of the plants standing alongside. To generate a beating effect on the cutter, an eccentric shaft or an unbalanced shaft can be provided.

Title: Circuit-switching packet switching device
Inventor: BOETTLE DIETRICH DIPL ING
IPC: H04L49/111
Filed: 1988-05-17
Abstract: The invention achieves the object of devising a switching system which meets the requirements imposed on a modern packet-switching system and which simultaneously guarantees compatibility with a switching network. The basic notion is to apply the principle of virtual links, even in the case of packet links within the switching system, and to allocate a dedicated through-connected channel to each link. A packet switching device (11...16) with a demultiplexing or multiplexing function is in each case located at the input and output of the switching system. The switching per se is performed in a switching device (20). Compatibility with a switching network is achieved automatically. <IMAGE>

Title: Method for coding and checking information for safety- and security-related transmissions and device for carrying out the method
Inventor: KOEHLER KLAUS
IPC: H04L1/00
Filed: 1988-10-24
Abstract: To each information item of an information block consisting of a number of information items, two bit sequences corresponding to the two binary values of the relevant information item are allocated which are different from the other information items of the block of the associated bit sequences. In one binary value of an information item, one bit sequence and in the other one the other bit sequence is generated. The bit sequences are sent in an accurately defined order to which the receiving computer is also programmed. The bit sequences are provided by microcomputers (MC1, MC2) at the transmitting end which are controlled by binary input signals (E1 to En). The information items transmitted via a single transmission channel (Ü) pass to two microcomputers (MC11, MC21) at the receiving end, where they are evaluated in two channels. The transmitted information items are recognised only when the associated bit sequences are received in the defined order. Using complementary bit sequences for the two values of the information item and the arrangement of these bit sequences in a defined and checked order results in a large Hamming distance compared with unrecognisable corruptions of information items. <IMAGE>

Title: Sound-damping means for gears
Inventor: JOACHIM FRANZ-JOSEF DR
IPC: F16H57/00
Filed: 1989-03-06
Abstract: The sound-damping means for gears (1, 2) consist of annular discs (3.1 and 3.2) made of a sound-refracting but nevertheless mechanically dimensionally stable material which axially cover said gears only at the gear rim or in the region of meshing. The discs (3.1 and 3.2) have a radial width reaching above the tooth tip circle (7) and below the tooth root circle diameter (6) of the gear (1 and 2) carrying the friction disc (3), respectively. By means of an axial gap (8) between the gear rim end face (4 and 5) and inner surface of the annular disc (3), good ventilation and oil exchange in the radial direction from the respective cavities (14.1 and 14.2) forming in the meshing region are possible. By means of the annular discs (3.1 and 3.2) fastened on the gear rim under prestress, both the structure-borne sound and the airborne sound are retarded and refracted directly in the region of their occurrence. Since the gear webs can remain uncovered, their surface remains accessible to unhindered cooling. <IMAGE>
