Patent DE-2426921-A1 (DE)
Title: AC mains operated battery charger - has two time detectors operating connecting switch, one used as safety device and one for final charging
Inventor: MEYER-STAUFENBIEL TORSTEN
IPC: H02J7/00
Filed: 1974-06-04
Abstract: The battery charger, fed from alternating current mains, has a switch for connection of the supply voltage, a transformer, and a rectifier in the charging circuit. The control circuit switch is actuated by two time detectors, one monitoring the total charging period and serving as a safety disconnector, while the other one determines the final charging period after the charged battery has attained its gassing voltage. This second time detector is formed by a combination of a pulse generator and an electric counter, actuable by voltage dependent threshold switch. The counter actuates the switch of the charge circuit after an adjustable final charging period. Preferably the output of the counter is connected to the charging circuit switch via an amplifier.

Title: Platform hoist for boats - with hydraulically moved rollers to compensate for different cable movements
Inventor: BERKE HANS DIPL ING
IPC: E02C5/00
Filed: 1974-09-18
Abstract: The ship is raised from the water by a special platform suspended from the supporting raft, or dockside by an array of cable winches. The raft is braced by cross frame members and in order to ensure an even loading, or rather even strain on the platform, the winch cables are each looped over fixed rollers on the supporting platform and are taken in horizontal loops over special rollers which are moved horizontally by hydraulic rams. The rams are all set coaxial on one side of the structure. The rams are easily balanced so that an even strain is possible with a minimum of complexity.

Title: Carbon monoxide reducing fitting for inlet manifold of engines - admits water satur air through fine bore
Inventor: WYMAN CURT R
IPC: F02M25/022
Filed: 1974-11-08
Abstract: The CO concentration in the exhaust gases of IC engines is reduced by screwing into the wall of the inlet manifold, a threaded fitting with a thin longitudinal bore, which introduces atmospheric air which can first be passed through a water trap, with an addition of methanol or ethanol. Provides an almost complete combustion of the fuel, particularly when coasting downhill with the butterfly valve nearly closed. The air stream causes improved turbulence and the cool moist air increases the volumetric efficiency of the engine. The fitments are easy to make and to install.

This arc lies in a plane passing through the passage centre line and at right angles to its base, and the wheel can be brought to bear against the end of the row of items. In its two end positions the lever can actuate feelers dependent on whether items have accumulated in the passage, or are absent from it. In the former eventuality the feed of items into the passage is halted, and in the latter the wheel is stopped.

Title: Support frame for inside of horsebox - has frame sections deformed in collision to absorb impact and lessen injury
Inventor: ULLSTEIN HANNS
IPC: B60P3/04
Filed: 1975-05-09

Title: Yarn winding onto cross and cone bobbin - at constant speed from texturising machine without rewinding
Inventor: WROCLAWSKI ZBIGNIEW DIPL ING
IPC: B65H54/10
Filed: 1975-11-07
Abstract: Yarn is fed at constant speed onto a conical shaft to form a cross-and-cone wound bobbin. A pair of yarn take-up shafts feed yarn at constant speed. A vacuum receptacle receives yarn and temporarily accumulates it. This receptacle consists of a holding chamber, suction chamber, a device that measures the filling in the holding chamber and a sepg. wall between the two chambers. The wall has two rows of yarn loop forming parts. A conical support shaft receives yarn from the holding chamber and conical drive shaft winds the yarn on the support shaft. The shafts have axis at an acute angle to each other and a controller displaces the conical support shaft relative to the drive shaft to compensate for the varying dias. of the conical bobbin yet still maintain the same feed rate. Yarn is wound at constant speed from a non-spinning frame in a yarn texturising machine into a cross-and-cone bobbin. Ordinarily in this operation it would have wound into a cross-and-cylinder bobbin and then rewound. Thus by this method rewinding is avoided and good quality bobbins are obtd.
