Patent DE-2417493-A1 (DE)
Title: High speed chain printer for use with e.g. computers - has fewer printing hammers than symbols on chain
Inventor: BELGE DIETER
IPC: B41J1/20
Filed: 1974-04-10
Abstract: The drive unit for the stepwise powered print chain consists of a stepping motor controlled by an electronic impulse generator. These impulses are also fed to a counter whose output information is supplied to a shifting register in the form of codes corresponding to the position of the symbols on the print chain. A register is associated with the shifting register and is used to store the information which is to be printed out. Comparison logic is provided whereby a print command is generated when a coincidence is detected between the contents of the register and the information in the shifting register.
Patent DE-2419668-A1 (DE)
Inventor: GALATIS TELEMACHUS NICOLAS
IPC: G01M3/16
Filed: 1974-04-24
Abstract: The invention provides a method and apparatus for detecting impairment of the integrity of barriers used for the containment of fluid materials, particularly fluid materials at cryogenic temperatures, e.g., liquefied natural gas. The detection system employs electrical conductors which are in physical relationship to the barrier and undergo a change in current conducting function in the event of barrier failure. In the containment of fluid at low temperatures the detection system preferably comprises conductors which have temperature dependent resistances and are embedded within the thickness of the barrier. By distribution of conductors over different notional zones of the barrier area and provision of associated warning devices the location of leakage points within the barrier area can be automatically indicated.

Title: Low impedance flash-tube trigger circuit - permits rapid triggering of brief flash, especially for copiers
Inventor: RECH WERNER DR RER NAT
IPC: H05B41/32
Filed: 1975-11-24
Abstract: A circuit for triggering a gas-discharge flash-light with the flash-tube in parallel with a condenser across a voltage source together with a high tension triggering generatorgenerator (4, 5, 7) has such a low impedance, especially in respect of its inducatnace, that the triggering pulses which it supplies can heat the discharge plasma approximately adiabatically during ignition. The trigger pulses may be generated by a capacitor (4) charged from a source (5) with protection by a chain of blocking diodes (6) or by a piezoelectric crystal (7) with a suitable pressure device. The result is to avoid the normal-over-dimensioning required of the flash capacitor and supply with a high impedance trigger device to ensure reliable starting of the flash. The system is especially suitable for high speed copying machines requiring short exposures.
