Patent DE-2622680-A1 (DE)
Title: Sprinkler installation with permanently open alarm valve outlet - has water closing flap operated by fault monitoring control system
Inventor: BUESSEM RUDOLF DIPL PHYS
IPC: A62C37/36
Filed: 1976-05-21
Abstract: The alarm valve (10) is connected to the layout in such a manner that on one valve connection the water inlet (11) and the outlet end the riser (12) of the Sprinkler distributing grid is fitted. The distributing grid side including the chamber (14e of the valve (10) is under gas pressure. The water supply into the chamber is closed up by flap (13) held in closed position by lug (16) of toggle lever (15) which is part of a locking mechanism. The arm of the toggle lever rests against rod (19) on the end of which diaphragm (20) is fitted. Lug (27) fitted on the rod works together with toggle lever (26) operated by solenoid (25). The solenoid is permanently energized as long as the fire alarm system is intact. In case of a faulty alarm system and fire, the solenoid causes the release of the entire blocking leverage and the flap (13) opens admitting water into the riser (12).

Title: Milling cutter under cutting mechanism - has main spindle gear driving shaft with cam disc acting on differential
Inventor: WAGENZINK GUENTER
IPC: B23Q11/00
Filed: 1976-07-12
Abstract: The mechanism is for the undercutting and grinding of milling cutters with unevenly-spaced chip grooves, the lifting disc for the undercutting slide being driven from the main spindle via differential. Between the spindle and the disc is a shaft on which a cam disc is fixed, and the spindle drives the disc via gears whose ratio is a whole number. The cam disc peripheral surface acts on the differential via a inkage and preferably a worm drive. Thus the axial movement derived from the rotating disc in conjunction with the differential imparts an additional rotary movement to the lifting disc corresponding to the cam disc profile.

Title: Vehicle braking characteristic direct display method - uses X-Y plotter receiving braking torque signals to provide continuous record of braking
Inventor: BECHTOLD HORST ING GRAD
IPC: G01L5/26
Filed: 1976-09-23
Abstract: A method and device for determining the braking characteristics of a vehicle are partic. used for evaluation of the relations between wheel braking torque and time, speed and/or deceleration. While conventional methods enable only average value measurement, this method provides continuous information. An electrical signal representing the braking torque is combined with its corresp. independent variable on an x-y recorder display to directly show the characteristic required. The torque signal is input to the dependent variable connection and a time, speed, or deceleration signal to the independent variable connection. The torque signal may be derived from strain gauges fitted to measurement wheels and connected in a bridge circuit.

Patent DE-2647118-A1 (DE)
Inventor: MIYAKE TAKAO
IPC: B65H69/00
Filed: 1976-10-19
Abstract: An automatic knotting machine (10) is arranged opposite the winding appliances (1-1 to 1-10) so as to be displaceable along a rail (11). When knotting is to be carried out on a winding appliance, the knotting machine stops at the respective winding appliance and carries out the yarn knotting. Each winding appliance possesses an inert-gas switch (12-1 to 12-10), which switches react to a magnet (14) arranged on the knotting machine. The signals generated by the inert-gas switch are fed to a signal converter in order to convert the said signals into signals coded according to the individual winding appliances. A timing circuit supplies to a computer only those coded signals which last longer than a time determined by the timing circuit. Only these longer-lasting signals are recorded and counted. In this way, the number of knots of a large number of winding appliances can be determined quickly and without a high material outlay. <IMAGE>

Title: AF control system for power distribution networks - sends switching commands partly via control lines separate from power network
Inventor: JUNIOR HANS DIPL ING
IPC: H02J13/00
Filed: 1977-03-11
Abstract: The AF control system, is for power distribution networks. It sends out switching commands to local receivers partly via a control line (6) separate from the power network. The switching commands and control signals are sent via a completely separate line for the high voltage (1) and medium voltage (2) levels of the network, whilst at the low voltage level (3) they are sent via the power lines themselves as AF signals. The advantage lies in simplifying the sending and receipt of commands and signals.

Patent DE-2809110-A1 (DE)
Inventor: KUBIK FRANTISEK
IPC: E21B19/16
Filed: 1978-03-03
Abstract: Process and device for connecting in a tight manner the end of a pipe presenting a cone thread to a corresponding tubular sleeve and subjected to high torques. The holding forces generated by the clamp chucks create some deformations in the pipe which make a tight screwing more difficult. Further, the speed changes of the massive clamp chucks require slow rhythm of work and drive powers which are not compatible with a rational mounting system. The invention provides for a two-step process, wherein an auxiliary spindle (19, 20) is screwed into the sleeve (14) which will be screwed to the extremity of the pipe (5) by means of said spindle (19, 20). This auxiliary spindle (19, 20) is then removed and the end of the pipe (5) and the sleeve (14) are further tightened one against the other under high torque by two rotating clamp chucks (2, 9). The clamp chucks are disposed in such a manner that they allow eccentric and angle variations to take up the mounting tolerances of the pipe sections (5, 14). The clamp flanges (26) are hydraulically operated and hold the pipe sections (5, 14) substantially around the whole contour thereof. The device is preferably used for the preassembly at the factory of pipes aimed at being engaged in oil-well drillings.
