Patent DE-1947801-A1 (DE)
Inventor: VOESTER SITTMANN GEB
IPC: E05D15/526
Filed: 1969-09-20
Abstract: The actuating fitting is used for holding windows or doors at a required opening position. It is used especially for combined tilting and rotating windows. The mechanism has a locking bolt placed behind a locking wall plate in closed position of a panel. - This bolt blocks automatically the adjusting arrangement against actuation when the panel is opened. The moving panel is prevented from simultaneous rotating and tilting movement even if the opening positions for this purpose are arranged side by side for the adjusting movement of the lever system. - The locking bolt (21) for adjusting mechanism (12) becomes effective only after a certain idle movement angle alpha. A partition wall (17) has two openings (19, 20) directly side by side for the locking bolt. This wall projects so far in closing direction that the locking element must be pulled back to or almost into the closing position on changing over the locking element from one opening position into other opening position.

Patent DE-2346528-A1 (DE)
Title: Variable time base for switching - on-off switching of power circuit controlled by input transducer with pre-selected on-off periods to a given sequence
Inventor: TESCH KLAUS
IPC: G05B19/07
Filed: 1973-09-15
Abstract: A precise time base is for on-off switching of power circuitry to a fixed sequence dependent upon the state of a measuring transducer e.g. temperature sensor. This is provided by bistables operated by a variable pulse generating circuit. In the specific example, the sensor contacts are coupled to switching relays, the contacts of which are connected to bistable relays connected in series across the pulse generating circuit. The pulse generator consists of two coupled bistables controlling the switch on and off points. When the supply to the circuit is connected, delay relays across the input lines ensure a preferential start-up state for the bistables. As soon as the input transducer switches the first bistable is set and an output order is generated for a period determined by the signal generator. At the same time the second bistable is put to a state of readiness. This procedure repeats each time the sensor contacts operate, with each bistable in the chain actuated in sequence.

Title: Textile fibre bundle packaging machine - has radial lugs on thruster heads acting against inside of package former
Inventor: SIEGLEN ROLF
IPC: B65B13/20
Filed: 1974-01-28
Abstract: The fibres are tied in position after compression onto a central cylindrical package former and held together by devices acting against the ends of the cylinder during the tying operationand subjected to pressure in the axial direction from the thruster heads. The holding devices are in the form of pressure lugs, extending radially outwards and pivoting in the respective heads. When the heads are pulled apart, they swing inwards and are thus extracted from the packet. The lugs can be joined by a U- or L-shaped portion to their pivot points, this portion being situated roughly level with the midpoint of the respective lug. The thruster head can have an auxiliary mandrel extending inside the packet, with slots in it into which the lugs retract, and acting as guides for the latter.
