Patent DE-2801306-A1 (DE)
Title: Positioning drive for machine component - has weight utilisation unit producing necessary force to move linkage
Inventor: NUSSER JOSEF
IPC: F03G3/00
Filed: 1978-01-13
Abstract: A weight (1) is guided in a track (2) which forms a continuous oval curve. The angular velocity of the weight varies inversely with the radius (3, 4) of the curve. A counterweight (1a) projecting from the weight (1) rotates the latter so that the arm between them is always radial. A spring mass system (5) or other device exerts a force on the weight (1). This force is controlled according to the requirements of the machine to accelerate or retard the weight. The mechanism can be attached to a machine element to produce any required movement and eliminates the use of electric drives.

Title: Determn. of surface tension of liq. - by formation of hemisphere of liq. at lower end of tube open at bottom
Inventor: KOPPE KONSTANTIN DR ING
IPC: G01N13/02
Filed: 1978-02-21
Abstract: The surface tension of a liq. is determined by producing a geometrical quantity which is dependent on the form of the hemisphere of liq. The pressure conditions in the vicinity of the head of liq. in the tube are measured. The tube may be positioned vertically or it may be arranged diagonally with its lower opening placed horizontally. Two measurements may be made when there are different hemisphere forms or when there is one hemisphere form and the other one is mixing.

Title: Liq. or fluid level indicator - has optic fibres bent in loops at various heights in container so that their light conduction depends on whether they are submerged
Inventor: SCHNEIDER WOLFGANG DIPL PHYS D
IPC: G01F23/292
Filed: 1978-03-07
Abstract: The level indicator has an elongated device extending in the container (3) upwards. It has light conducting properties and a light source, so that the level can be read from the received light flux. The device(4) consists of individual optic fibres (1, 2) which conduct the light in the vessel in accordance with the fluid level. The indicator lamp (5) can be a l.e.d. or incandescent lamp. If the level (6) reaches, e.g. the bend (7) of the optic fibre (2), the light from this fibre enters the liq. or fluid in the vessel (3). If the level (6) remains below, e.g. the bend (8) of the optic fibre (1), the light from this fibre is transmitted through a lens (10) at the other end.

Patent DE-2817656-A1 (DE)
Inventor: UEDA MAKOTO
IPC: H02P8/02
Filed: 1978-04-21
Abstract: An electronic timepiece including a dividing circuit for developing different output pulse signals having different respective pulse repetition rates, a stepping motor and a drive circuit responsive to control signals for driving the stepping motor at a normal rate and for applying a correction pulse to the stepping motor according to the control signals. A pulse combining circuit combines the different output pulse signals from the dividing circuit for generating control signals and for applying the control signals to the drive circuit. The pulse combining circuit normally generates a control signal effective to drive the stepping motor at a normal rate, and the pulse combining circuit is responsive to a correction signal to control the drive circuit to apply a corrective pulse to the stepping motor. A detection circuit detects rotation and non-rotation of the stepping motor rotor and generates a detection voltage signal indicative of the state of rotation of the rotor. A voltage comparing circuit compares the detection voltage signal with a standard voltage value and applies a correction signal to the pulse combining circuit when non-rotation of the stepping rotor is detected after a drive pulse is applied to the stepping motor.

Title: Spring friction damper for suspended conductor - has two-piece conductor clamp for attaching helical spring and inertial weight to conductor
Inventor: HAWKINS ROLAND GEORGE
IPC: H02G7/14
Filed: 1978-08-24
Abstract: The damper comprises at least on helical spring, at least a portion of the turn of which are close wound and a two piece conductor clamp for attaching the spring to a conductor in spaced relation to it. At least one inertial weight is mounted on or attached to the spring so that the weight can be resiliently suspended from the conductor by the spring and attaching. The inertial weight is effective to relatively translate and thereby provide sliding friction between the close wound turns of the spring in a direction perpendicular to the axis of the spring when an associated conductor undergoes vibration above a given magnitude. The weight bends the helical spring such that adjacent close wound turns of the spring separate from and impact against each other.

Inventor: TAKEDA RENZO
IPC: G21C19/20
Filed: 1978-09-12
Abstract: A method of refuelling a boiling water reactor consists of subdividing the central region of the core, amounting to 50%, into gps. of four adjacent fuel assemblies in each gp. one only of the fuel assemblies is replaced by a new assembly in each fuelling cycle. Pref., the four assemblies in each gp. are replaced by new ones at regular intervals, more specifically at intervals of one year; i.e. assembly (1) might be replaced at the end of the first year, assembly (2) at the end of the second year and so on, for each gp. Reduced refuelling times are obtd. A sufficiently low max. linear heat generation coefficient and effective and economic utilisation of the fuel are achieved. By compositing each gp. of four fuel assemblies, the optimum fuel life of four years can be achieved for each assembly by refuelling once a year. In addn., the gp. of four forms one unit around a central neutron detector.

Title: Flash butt welding machine - with sensors for all parameters affecting weld quality (OE 15.6.80)
Inventor: LIFSCHIC VIKTOR S
IPC: B23K11/24
Filed: 1979-04-10
Abstract: A butt welding machine is equipped with a minicomputer for the automatic control of the start of the upsetting operation and the upsetting distance.

A command shaper is controlled by the minicomputer output. The presence of sensors for all possible defects ensures a consistent high quality of the butt welded joints produced by this machine.
Patent DE-2923676-A1 (DE)
Title: Hydraulic synchronising mechanism for heavy vehicle gear box - has coupled hydraulic pump which acts to retard or accelerate lay shaft
Inventor: MAHLER HEINRICH DIPL ING
IPC: B60K17/00
Filed: 1979-06-12
Abstract: The application is to gear changing on heavy vehicles. The arrangement gives power assistance to the synchromesh equipment in order to give quick gear changes and reduce the physical effort required from the driver. A hydraulic pump is permanently connected to the lay shaft of the gear box. In steady state operation of the vehicle, the pump provides hydraulic power, and also keeps a pressure receiver charged. When changing to a higher gear, the pump acts as a brake on the lay shaft, reducing its speed by absorbing some of the energy in the rotating mass. If a lower gear is to be engaged, the pump is changed over to the motoring state by connecting it to a hydraulic supply. It then accelerates the lay shaft to the new operating speed, reverting to the pump mode again when the gear is engaged. Switching of the hydraulic circuits may be accomplished by an electromagnetic valve.

Title: Control system for pulse column - having logic arrangement which maintains all elements in same proportion if overall pulse frequency is altered
Inventor: DOEBELE RUDOLF DIPL ING
IPC: B06B1/20
Filed: 1979-08-04
Abstract: Pulsations are generated in a mass transfer column by intermittent application of compressed air to a branch at the side of the column which transmits a pressure pulse into the column. The control circuit has a timer which generates a rising potential, the rate of rise being constant over a certain time. The total duration of the period can be adjusted which thus adjusts the rate of rise. The rest of the logic circuit is triggered to certain voltages within the range. Thus the cycle can be extended or reduced in time with all events occurring in the same ratio to the total period merely by making one adjustment. Used to increase effect mass transfer in liquid contact columns and allows optimum air usage by maintaining the optimum time ratios within the whole cycle, the time of which can be varied.
