Patent DE-2332315-A1 (DE)
Title: Cranked pivoted leverage mechanism - used specified lever arms for force or load reduction or compensation for mechanical equilibrium attainment
Inventor: BERGMANN REINHARD
IPC: F03G7/10
Filed: 1973-06-26
Abstract: The lever arrangement comprises a horizontal force arm which, at the pivot point, is rigidly connected with a load arm. The load arm is upwardly inclined and preferably includes an angle in excess of 125 deg. and less than 180 deg. with the force arm, the arms preferably being of equal length. With load and force being in vertical direction equilibrium will occur between a given force and a greater load. A small increase of the force will disturb equilibrium in favour of the force. A mechanism may be provided to reduce the force arm in a predetermined way, so that, after a small angle of rotation, equilibrium is again achieved.

Title: Telescopic crane jib - rolling bearing guides at telescopic joints
Inventor: SCHARDT GEORG
IPC: B66C23/70
Filed: 1973-08-16
Abstract: The rolling bearing tracks at the telescopic joints of the crane jib are arranged in such a manner that the rolling bodies run in a direction parallel to the longitudinal axis of the jib.

The adsorbent is impregnated with CoO and Mo2O3 or W2O3 or NiO and Mo2O3 or W2O3, whilst (gas contg.) H2 is used for desorption. Pref. adsorption takes place between ambient temps. and 120 degrees C and desorption is at 200-450 degrees C. The adsorbent is pref. impregnated with not >10 wt.% of the metal oxides, with a molar ratio of CoO and/or NiO to Mo2O3 and/or W2O3 of ca. 1:1.5. The desorption gas, contg.

Provides a simple, effective and economical means of removing S from gases from any source. Redn. of the SO2 to H2S takes place during the actual desorption stage and not later in a separate redn. reactor. If the desorption cycle is reduced, a H2S:SO2 vol. ration of 2:1 can be obtd., as required for the Claus process.

Title: Drill guide for linked parallel holes - has second bore cut with aid of guide bar and bush to avoid wandering
Inventor: ROSE PETER ING GRAD
IPC: E21B19/24
Filed: 1974-12-24
Abstract: Long bores breaking into each other, are machined by cutting the second bore with the help of a guide bar and bush arrangement which follows the first bore. The alignment of the boring head is then not dependent upon the forces working on it whilst the second bore is being cut. The bores can be machines parallel without the deflection caused by differences in resistance to the cutters during their passage. In the first bore a comparatively short guide bar (4) has secured to it a sleeve (5) through which the boring bar (3) carrying the cutting head extends. Oil is fed directly to the cutters so that adequate lubrication is also available in recesses to give hydrostatic bearing protection against shock loading.

Title: Detection of short circuits between electrodes of electrolytic cell - by detectors which operate by magneto-motor force positioned by an automatically controlled overhead carriage
Inventor: KOBAYASHI TAKESHI
IPC: G01R31/02
Filed: 1975-06-02
Abstract: Detectors placed between the individual anodes and cathodes of an electrolytic cell each comprises a bladed commutator, which is kept normally open by an external magnetic field, linked to a permanent magnet by a shaft used to adjust the relative positions of the commutator and magnet. When a short circuit is detected the permanent magnet applies a force opposite that of the external magnetic field, closing the bladed commutator and lighting an indication light on the detector. The detectors are mounted on a horizontal bar connected to an overhead carriage travelling on rails which traverses a bank of cells. This carriage is connected to control circuitry which allows it to lift the detectors from the electrodes and move on to the next cell automatically if no short circuit is detected in a given time. The driving of the carriage along the rails and the raising and lowering of the detectors is done by separate motors positioned on the carriage. Sensors on the carriage stop it when it has moved to the correct position over the following cell and cut the motor lowering the short circuit detectors when it has lowered the detectors sufficiently. If a short circuit is detected the control circuitry keeps the carriage and detectors positioned at the short circuit.

Title: Motor vehicle fuel consumption meter - combines electrical signals of fuel flow rate and road speed transducers
Inventor: KNIRSCH ERICH
IPC: G01F1/28
Filed: 1975-07-15
Abstract: The vehicle petrol consumption meter comprises two transducers to measure fuel flow rate ad vehicle speed respectively. A transducer to measure fuel flow rate is placed in the fuel line between the pump and the engine. The measuring device can be either a potentiometric type or a magnetic transducer installed in the fuel pump.
