Patent DE-2457757-A1 (DE)
Title: Bottle packaging and handling - containers lifted from dispatch container and placed on discharge surface
Inventor: MNILK REINHOLD
IPC: B65B21/18
Filed: 1974-12-06
Abstract: A bottle handling system includes placing the bottles in or removing them from a dispatch container moved to an off-loading position at which the bottles are lifted from the dispatch container and after being positioned on a run-off surface are removed from the off-loading position. The dispatch container brings the bottles in the off-loading position above the run-off in which the bottles are lifted from the dispatch container and the dispatch container removes from the off-loading position. Subsequently, the bottles are lowered through the support surface of the dispatch container onto the run-off surface. In the meantime, a further dispatch container or a group of dispatch containers is moved in the off-loading position above the run-off surface and a loading cycle takes place in a reverse order.

Title: Electronic oscillator having control and regulating circuits - is applicable to energy or standby power supply units
Inventor: UDVARDI-LAKOS JANOS DIPL ING
IPC: H02M7/517
Filed: 1975-07-17
Abstract: The electronic oscillator has a regulating and control circuit and there is an unclamping circuit between it and its power stage. There is a receiver circuit which is connected, via a filter and the wiper contact of a switch, to a voltage source or to the output stage of the oscillator which is supplied from a battery d.c. source.

Patent DE-2550940-A1 (DE)
Inventor: JAUNICH GERD
IPC: G01M3/16
Filed: 1975-11-13
Abstract: In order that it is possible to locate moist points accurately and without any influence from interference voltages and temperature influences and in order that a plurality of moist points can be detected simultaneously, measurement points (3) are inserted at intervals between two longitudinally running, insulated, twisted copper cables (1, 2). The cables (1, 2) and the measurement points are embedded in the heat insulation of the pipeline. The measurement points (3) each consist of two electrically conductive plates (6, 7) between which an electrically insulating material (8) is arranged which absorbs water, for example blotting paper. If moisture is present, a shunt path is produced between the two cables (1, 2), which shunt path can be located precisely as a reflection point by connecting a pulse-echo test set (reflectometer). <IMAGE>

Title: Stepless variable speed friction coupling - has radially adjustable rollers within resilient band linked through universal joints
Inventor: WUERTH GUSTAV DR
IPC: F16H37/08
Filed: 1976-02-06
Abstract: The coaxial shaft coupling transmits infinitely variably between zero and one-to-one. Radially adjustable friction surfaced rollers link with planet gears axially, through universal joints. The rollers rotate on a transversely tightened band. For heavier duty the band is a roller chain, engaging with sprockets instead of rollers. The input spider shaft carries four or more equispaced driving rollers, telescopic universal jointed links, and planet gears. The radially movable rollers engage a semicircular steel band. At a set minimum radius the rollers and planets revolve without driving. Increased radius, and friction, rotates the sun wheel output.

Title: Handling system for wet and preheated coking coal - permits conversion of existing plant, eliminates risk of explosion
Inventor: OLESCH HELMUT ENGELBERT
IPC: C10B31/00
Filed: 1976-02-21
Abstract: The parent patent describes the mechanical handling of coal between the storage tower and the preheating plant for its preparation for charging into the coke ovens. In this addn. a transporting installation for coking coal between the preheaters and the storage tower, has batteries of hot coal storage and metering bunkers arranged on each side of the tower for loading the oven charging wagons. The storage tower has in addition to the chutes for filling wet coal into the charging wagons, metering valves feeding the conveyors transporting the wet coal to the preheaters. From the preheaters the self-compensating conveyors return the hot coal to a junction on the tower where ancillary belts distribute it to the laterally positioned hot coal bunkers. The ancillary belts may be erected inside or outside the tower. Excess gas from the preheaters is fed into the enclosed hot coal conveyor system and fills all the otherwise unoccupied space. It flows through the hot coal bunkers and the metering hoppers and finally through cyclones for the collection of fines before being vented to atmosphere. The transporting of the preheated coal is effected by way of conventional coal towers and charging wagons which function as normally, but at the same time take over the transport of preheated coal. Coking installations which were not planned for use with the preheating of coal, can in many cases by converted.

Title: Frequency bands changeover transceiver - uses several varactor-tuned oscillators with capacitors
Inventor: FRANKE MANFRED
IPC: H04B1/50
Filed: 1976-02-25
Abstract: The transceiver has its oscillators switched with no delay from transmit to receive frequency bands. Each frequency band has its own oscillator and each oscillator has a varactor diode and fixed capacitor. The varactor diodes have values such that the same change in the magnitude of the control voltage for all oscillators causes roughly the same absolute change in the frequencies of the oscillators. The series-coupled varactor and fixed capacitor are shunted by the inductor belonging to the that oscillator's resonant circuit.

Title: Automatic production of sweet water utilising marine energy - by harnessing waves to drive pumps and refrigerate vapour
Inventor: JUGL KURT
IPC: C02F1/18
Filed: 1976-03-12
Abstract: Sweet water is produced by using the energy of the waves; sea water being pumped by appropriate means to a height where it is heated by the sun's rays and then vaporised in a container filled with stones. The vapour condensing on the walls of a distillation arrangement is collected and pumped away to a reservoir for consumption. Pref. the plant consists of a large bell of synthetic material arranged at the surface, possibly between projecting pieces of land. Above, it has a pressure valve and a nonreturn valve, connected by lines to a bellows operating a rocking level. The lever moves a double rack with two ratchet wheels side by side which turn a dish rapidly in one direction driving pumps to lift the water into large containers. Similarly, a large plastic globe may be used to pivot a rocking lever directly. Distillation takes place in a large container housing a series of devices. There is a stack of stones on the floor of the container and there is a drain for the undistilled salt water. Collectors gather the condensate, and the housing is cooled by a compressor.
