Title: Swivel device for windows and doors, especially turn-and-tilt windows, doors or the like
Inventor: RIEDEL WERNER
IPC: E05D15/52
Filed: 1982-11-10
Abstract: Swivel devices are to be safeguarded against unauthorised opening from outside when the wing is in the tilted position. A suspension of the bearing member (11) is to be possible in any wing position and a removal thereof is to be possible only in the closed wing position or, according to the shape of the bearing bolt, in one or more further turning positions of the wing. This is achieved by means of a specially shaped bearing bolt (2) and a corresponding recess (12) in the bearing member (11). In specific wing positions, by means of the blocking nose (15) at least one safeguard element (13) prevents the possibility of pressing the bearing bolt (2) upwards axially (24). A further catchnose (16) of the safeguard element (13) retains the bearing bolt (2) when the bearing member (11) is to be inserted into the free space (10). A stop (14) formed on the safeguard element (13) prevents the possibility that the bearing bolt (2) will be lost. <IMAGE>

Title: Guide nut for gear-shift chains on bicycle gear hubs
Inventor: WEISSENBORN GERD
IPC: B62M25/02
Filed: 1982-11-12
Abstract: Despite the state of perfection and proven quality of known bicycle gear hubs, the associated gear-shift chain forms a weak point. Due to the friction against the rigid guide nut a sensitive gear-shift chain is gradually worn away and deformed; faults, difficulty in changing gear and total failures are the consequence. The guide nut with movable guide roller deflects the gear-shift chain in an extremely smooth manner and produces a gentle, sensitive actuation of the gear change. The protective cap protects the chain from damage and corrosion. Because, as is known, the end position of the guide nut, which serves simultaneously as wheel attachment nut cannot be determined in advance when fitting the guide nut, the swivel plate has the function of swinging in the guide roller into the correct position with respect to the gear cable.

Patent DE-3303537-A1 (DE)
Title: Locking spindle for pressure wheels, belts or the like
Inventor: DOTTER FRITZ
IPC: B41K1/12
Filed: 1983-02-03
Abstract: A locking spindle (1), preferably made of plastic, contains locking balls next to one another in a groove running in its longitudinal direction, which locking balls are held in the upper position by a resilient cushion, but cannot leave the locking spindle (1) on account of undercuts integrally formed onto the latter on the upper edge. Instead of individual compression springs for each ball and individual channels for these balls with their springs, in this arrangement it is possible to provide in an advantageous way a continuous groove into which a single continuous cushion for all the balls can be inserted. As a result, the advantages of the locking balls can be retained, but assembly and production can nevertheless be speeded up and simplified. <IMAGE>

Patent DE-3347549-A1 (DE)
Title: Method and device for forming a network-synchronous oscillation
Inventor: FISCHER ROBERT DIPL ING
IPC: H02M7/162
Filed: 1983-12-30
Abstract: A coordinate converter 3 forms the spatially-fixed orthogonal components of a vector which is allocated to the network. A vector rotating device 4 determines the direction of the vector in a reference system which rotates at a frequency. This direction and a corresponding desired value are predetermined to a regulator 6, the regulator output variable forming the control variable from which a control element 11 supplies the directional components cos  alpha , sin  alpha  of the rotating reference system. These components are on the one hand fed back to the vector rotating device 4 and on the other hand are picked off as network-synchronous voltages. Since brief network feedback effects of a connected load can lead to phase shifts, a detecting device 7 produces a signal for the regulation deviation if a limit value is exceeded, by means of which signal a switch 5 briefly connects the value zero to the regulator 6. <IMAGE>

Title: Self-generating two-key system for data access protection
IPC: G06F21/34
Filed: 1984-03-29
Abstract: Access protection by automatically generating a "password" unknown to the respective user himself, by using a random-number generator (or similar) in the user computer.   - Storage and provision of this password in divided form (two- or multi-key system) on at least two independent permanent memories, at least one of which must be portable. (The latter is always physically located with the user such as cheque card and cheque book). - When accessing a computer centre, the separately stored password information items are assembled again and checked for known. If known, a new password is generated in the user computer, supplied to the computer centre and again stored in separate form. - The password in each case only has validity for a single self-contained data session and is automatically renewed in each subsequent session if a computer centre is accessed in the latter.   The generation, maintaining and renewing of the password in connection with a necessary user number in the above system represents a data access protection which can be called 100%. It is only such protection which, for example, enables external tape transactions or similar to be performed.

Patent DE-3430023-A1 (DE)
Title: Electrical hand tool having a ventilation device
IPC: H02K9/04
Filed: 1984-08-16
Abstract: In the case of electrical hand tools, for example electric drills, cooling is carried out with the aid of a ventilation device. If the ventilation device is driven in the normal manner via the drive motor of the electrical hand tool, particularly with the intermediate connection of a transmission, this means that the impeller wheel or the like will run slowly if the electrical drive motor of the hand tool runs slowly. On the other hand, however, a low rotation speed of the drive motor can result in quite a large amount of heat being developed. In this case, the cooling is then inadequate and this leads to damage to the motor. If, in a manner according to the invention, the impeller wheel or wheels (9) or the like are driven with the aid of an additional motor (8), the impeller rotation speed can be selected independently of the rotation speed of the electric drive motor (2) of the hand tool and can hence always provide effective cooling. However, on the other hand, it is possible to dispense with driving the ventilation device, which drive is associated with noises, in all those cases in which no significant heating of the electric drive motor (2) is to be expected. <IMAGE>
