Title: Method for stabilising the package end regions
Inventor: SCHIPPERS HEINZ DIPL ING DR
IPC: B65H54/28
Filed: 1988-08-01
Abstract: To prevent thread bolsters in the end regions of cross-wound bobbins which are formed in a winding machine having flyer traversing devices for guiding the thread to and fro along a straightedge, a method for stabilising the end regions of the cross-wound bobbins is proposed. A temporary displacement of at least one of the stroke ends within a predetermined total-stroke range is achieved by varying the position of the entire straightedge (26) transversely relative to the thread running plane at predetermined time intervals. For this purpose, the straightedge (26) can at predetermined time intervals be shifted perpendicularly to the traversing direction and parallel to itself or else be pivoted about a pivot axis into the thread running plane. <IMAGE>

Title: Single control for temperature-dependent heating elements
Inventor: GILLIG THOMAS DIPL ING
IPC: G05D23/24
Filed: 1988-09-07
Abstract: A single control for temperature-dependent heating elements is described, in which a voltage-regulating circuit is provided which controls an ignition circit as a function of a set desired value and the actual value of the heating element, the heating element being connected to the operating voltage by means of the ignition circuit via an electronically controllable power switch. It is the object, in particular when the electronically controllable power switch and the ignition behaviour connected therewith are heated, to regulate the heating element precisely. For this purpose, it is provided that the voltage-regulating circuit increases to a constant-current source fed by direct voltage, and that the ignition circuit is decoupled by means of a further electronically controllable power switch, in particular by means of a buffer thyristor.

Title: Telescopic sight mounting
Inventor: KEPPELER DIETER
IPC: F41G1/387
Filed: 1989-03-14
Abstract: The pivoting foot of the telescopic sight is inserted from the side, by means of a cone which is flattened on the sides and is tapered upwards, into a corresponding recess in a weapon rail mounted on the top of the shooting weapon (gun or bow), and is locked by turning it through 90@. Since the recess is incorporated over the entire width of the weapon rail, a large contact surface is produced for absorbing the recoil forces, with the consequence that a line of sight which is located correspondingly lower and, in consequence, improved aiming accuracy are made possible. A spring-loaded clamping slide is provided for play-free mounting, which clamping slide clamps the cone of the pivoting foot in the recess in the weapon rail. The rear foot of the telescopic sight is likewise constructed as a cone and is clamped in a recess in the weapon rail by means of a spring-loaded bolt part.

Title: Method for operating a ring-spinning machine and service robot for carrying out the method
Inventor: CITTERIO GIORGIO
IPC: D01H13/14
Filed: 1989-03-23
Abstract: A method for operating a ring-spinning machine by the use of a service robot patrolling along a row of spinning stations is characterised in that the service robot, in a first movement along the row of spinning stations, stores the spinning stations at which a thread break has occurred, and in that only in a further movement, preferably in the next movement along this row, does the service robot attempt to rectify the thread breaks previously detected and, after this attempt, it checks whether it has been successful, and, if this is not so, classifies the thread break as not repairable by it and indicates or communicates this fact to the attendance crew. Only in the event of a failure to eliminate a thread break is the slubbing stop device provided at the respective spinning station actuated. <IMAGE>

Inventor: SCHIERAU KLAUS DIPL ING
IPC: G08B17/12
Filed: 1989-07-21
Abstract: A fire detector contains at least one sensor element (16) which detects the heat emanating from a fire. The sensor element is constructed as a thermocouple (16) whose reference junction is thermally connected to a heat sink (18) which stores the heat and whose temperature corresponds to the mean temperature of the room. The temperature of the measuring point of the thermocouple is influenced both by absorption of radiant energy and by heating due to heat conduction. In the event of a fire, energy components of both types of heat transmission are detected by the thermocouple, so that the fire detector reacts to fires with a high sensitivity. In one embodiment of the invention, a test sensor (82, 84) which receives a test radiation (94) is arranged near the thermocouple (16). The test sensor (82, 84) generates a test signal with the aid of which the degree of pollution of an upstream protective glass (80) is detected.   <IMAGE>
