Title: Negative grid type plate for lead-acid accumulators - consists of copper grid tinned and plated with lead
Inventor: STEIG HANS
IPC: H01M4/68
Filed: 1974-01-31
Abstract: The negative electrode grid for Pb accumulators to obtain good conductivity, uses Pb covered Cu. The Pb grid or parts of it including the Pb frame and Pb head-bars, Pb crosss-bars and Pb flow bars are conductive and combined mechanical strengthening with Pb covered Cu conductors connected to a Pb-Cu compound body. A tinned and Pb covered Cu conductor at the upper edge of the grid extends as a cross-bar mainly over the full length of the Pb head-bar. The cross-bars have holes distributed over the length which match with corresponding Pb knobs producing a good contact between Pb knobs and cross bars. The connections may be rivetted. The weight of the Pb plates is reduced and their conductivity is improved.

Title: IC engine with crankcase suction pipe - has electric heater round crankcase suction connection to inlet manifold
Inventor: NONN MANFRED ING GRAD
IPC: F01M13/04
Filed: 1974-07-08
Abstract: An engine (10) has an inlet (11) with a suction pipe (16) leading to a fuel injection system (12). A branch pipe (19) leads from a point (17) in the inlet pipe to the crankcase sump (14). Gases collecting in the sump are sucked through this and join the fresh combustion air thus adding unburnt components from previous engine strokes to the entering mixture. At the point of connection (17) the joint is made by a coupling pipe which is surrounded by a concentric electric heating element with an outer covering. This raises the temperature and prevents condensation in the mixed gases. The heater is supplied from the engine battery through the ignition switch and has a rating appropriate to the minimum ambient temperature in which the engine is to run.

Patent DE-2440871-A1 (DE)
Title: Doppler radar navigation method for aircraft - determines ground speed by radiating A.M L.F test beams
Inventor: MAERZ KARL DR ING
IPC: G01S13/32
Filed: 1974-08-27
Abstract: The beams are radiated towards the ground, and keyed by coherent pulses. Aircraft speed is calculated from the Doppler shift scattered back and received in the aircraft signals. The coherent pulse keying is made by pseudorandom signals of a certain structure. These signals consist of periodically recurring pulse trains with 0, 1 pulses. Such pulse train duration is longer than propagation time of waves from aircraft at the highest possible altitude to ground and back. This arrangement avoids the appearance of high gaps in coherent pulse sensored navigation sensors thus obviating wobble installations changing the pulse repeating frequency which can produce ambiguities in the Doppler signal.
