Patent DE-2540636-A1 (DE)
Title: Safety belt variable strap brake - produces braking force acting directly on strap without use of prestress or deforming elements
Inventor: MUESSELER PETER DIPL ING
IPC: B60R22/28
Filed: 1975-09-12
Abstract: The variable strap brake is suitable for use on safety belt webbings as retaining device at sudden decelerations. It consists of two half-bushings seated in PTFE on two side dishes. The strap is inserted between the gaps of the half bush such that while the forming loop emerge from one of the gaps, the two free ends of the strap emerge from the other gap pointing in opposite directions. When tensile force is applied at these ends, the half bushes swivel in opposite directions and the gap through which the loop part of the strap threaded, closes to prevent the loop from being spent. A pin serves for producing an initial friction for keeping the loop in the original size.
Patent DE-2541405-A1 (DE)
Title: Preventing collision of moving parts - using transmitter and receiver for alternating electromagnetic fields to provide contact-free end switches
Inventor: BORN HEINZ DR
IPC: G01V3/08
Filed: 1975-09-17
Abstract: To prevent e.g. mobile bridge cranes which run at different levels from colliding, electromagnetic transmitters and receivers are used. When the two mobile elements approach each other, a spherical, alternating magnetic field is emitted from the transmitter. The receiver is such that it responds to spherical shaped magnetic fields. When the limit of the safe distance between the two mobile structures is reached, the receiver produces a command signal which stops the two driving motors. To avoid the possibility of coinciding sensitivity lobe characteristics both transmitter and receiver can be provided with two coils with their longitudinal axes positioned at right angles to each other.

Title: Flame welding, cutting and metallizing torch - has afterburning gas port after central cutting and peripheral heating gas ports
Inventor: ZELEY J ANTONIO
IPC: F23D14/52
Filed: 1975-10-23
Abstract: Torch is equipped with a central oxygen channel for cutting and peripheral channels for heating gas and heating oxygen. An additional port is arranged on the end face in the direction opposite to the direction of motion through which heating gas emerges to effect an after combustion. This produces a soft flame which has a smoothing effect during welding and flame metallizing. During cutting operations, the after burner gas can be introduced at a rate and pressure to ensure a reliable ignition flame.

Title: Push button combination lock with electronic coding - is powered by capacitor returning combination to zero after charge dissipation
Inventor: WILLACH HORST DIPL ING
IPC: G07C9/00
Filed: 1976-06-29
Abstract: The push button actuated combination lock has electronic coding. The electronic coding is complemented to ensure that it is foolproof and can be used with high degree of security. Only a few push buttons are used for ensuring relatively wide coding range. Each actuation of a push button, including multiple actuation, triggers an associated pulse or switching process. A capacitor is charged on actuating the first combination pushbutton. This charge supplies the power for opening procedures, and ensures that actuation of push button returns to zero value after short time when charge is spent and electronic system blocks the lock automatically.

Title: Circuit converting finely and coarsely quantised signals - has digital filter accepting noise components and supplying compensation with quantised stage
Inventor: KITA YASUHIRO
IPC: H03M7/00
Filed: 1976-12-03
Abstract: The circuit is used for transforming digital signals. This is done by transforming a finely quantised signal and a coarsely quantised signal. This applies for example in a combination of a differential pulse coding system and a delta modulation circuit. A digital pulse code modulation device transmits a digital pulse code modulated signal to the input (1) of the conversion circuit. The bits of the coded signal consist of higher and lower order bits. The higher and lower order bits of the coded signal are fed to a buffer register (9) and an accumulator (3) respectively. There is a digital filter which accepts the quantised noise components as an input signal and supplies a compensation signal which has a quantised station stage with a period equal to that of the coarse quantisation.
