Patent DE-2357521-A1 (DE)
Title: Carburettor with mixture control for cold start - has air intake for slow running jet between choke and fuel nozzle
Inventor: AUGUST PAUL DIPL ING DR
IPC: F02M23/12
Filed: 1973-11-17
Abstract: The carburetor has a main fuel nozzle in a venturi section of the air intake. The accelerator throttle is downstream of the fuel nozzle. Upstream of the nozzle is a choke operated damper throttle for cold starting purposes. An air passage leads to a slow running jet at the level of the accelerator throttle. A further passage to provide additional air for slow running conditions terminates in a calibrated outlet below the accelerator throttle. The air inlet to this passage is placed downstream of the choke throttle but upstream of the main fuel nozzle. This avoids weakening of the mixture during cold starting caused by a higher inlet pressure for the secondary air passage than for the main flow.
Patent DE-2364203-A1 (DE)
Title: Battery with a rechargeable zinc electrode - using porous nickel mesh between anodes and cathodes to stop dendritic growth
Inventor: BENDA KLAUS VON DR
IPC: H01M10/24
Filed: 1973-12-22
Abstract: The parent patent described a cell with a rechargeable Zn electrode surrounded by at least one conducting frame which is wetted by the electrolyte and is electrically sepn. from the electrodes; the frame has coarse pores and is made of a material on which a macroscopically visible Zn deposit from the electrolyte is obtd. at more negative potentials than those where a deposit occurs on smooth Ni or sintered Ni, and the surface of the frame contains catalysts for the oxidn. of hydrogen in fuel cells using aq. electrolytes. In the present invention, the frame has pores with a dia. of 0.05-1 mm, pref. 0.1-0.5 mm. The pref. pore dia. for fine Zn deposits is 0.1-0.25 mm and 0.25-0.5 mm for coarse in opposite polarity and improves the rechargeability of the cell by preventing the formation of Zn dendrites which extend to the cathode, thus causing short circuits. The small pores stop fine Zn dendrites from reaching the cathode.

Title: Steam drive regulation for power generation unit - has steam throughput controlled by outlet pressure
Inventor: SUTTOR KARLHEINZ DR ING
IPC: F01D15/10
Filed: 1974-03-29
Abstract: Steam drive for large industrial machines or mains power generation, has a steam engine and an asynchronous motor coupled to the machine; below the synchronous r.p.m. the motor functions as a motor, and above it, as a generator. Preferably, the outlet steam pressure controls the steam throughput through the steam engine. An electrical power value of the connected user(s) may alternatively regulate this throughput. Energy losses are avoided which arise from differences in the throughput of steam through the steam turbine and the steam requirement of the low-press. network or low press. user(s).

Title: Loudspeaker cct. with motion negative feed-back - voltages from motion pickups combined in one feed-back voltage
Inventor: BACKES WOLFGANG
IPC: H04R3/00
Filed: 1974-04-23
Abstract: Pickups are provided on identical or similar loudspeakers and combined feed-back voltage is applied to an amplifier driving all loudspeakers. This feed-back voltage is picked up not from all; only from some of the loudspeakers. Permeable to sound counter electrode for the negative feed-back voltage derivation is in the form of several similar diaphragms arranged next to each other. The variable capacitors (C1.. C4) are the capacitative sensors for four equivalent loudspeakers. The constant voltage source (U) causes currents to flow through the small resistors (R) corresponding to the speed of suction of the membranes. The voltage drops across the resistors (R) are added in a low-noise pre-amplifier (V1).
