Patent DE-2834411-A1 (DE)
Title: Lead accumulator plate block support - with U=shaped plastics clamp securing sides and top
Inventor: EISENACHER WERNER ING GRAD
IPC: H01M10/16
Filed: 1978-08-05
Abstract: Lead-acid accumulator has in each cell a block, consisting of plates and separators, of smaller width than the clear width of the cell. A U-shaped clamp, made of a thermoplastic such as polypropylene, is in close contact (welded) with the underside of the cell lid and has elastic side legs which take up the space between the block and the side walls. The legs do not extend to the bottom of the cell. This is very beneficial effect on the resistance of the accumulator to shocks and vibrations. The U-shaped clamp is easy to assemble and its assembly offers no difficulties to mechanisation or automation.

Title: Isomerising hops extract to form iso-alpha-acids for beer - treating with strong acid before alkali isomerisation
Inventor: HUMPHREY ANTHONY MARTIN
IPC: C12C3/12
Filed: 1978-08-23
Abstract: Process comprises extracting the hops alpha-acids with an organic solvent and transferring the alpha-acids from a non-polar water-immiscible solvent to water to form a soln. of alkali metal alpha-acid salts. Before conversion to the salt form, the alpha-acids are contacted with sufficient aq. strong acid to give a pH in the aq. phase after contact of 1. A particular process comprises contacting a soln. of the extract in a non-polar solvent of b.pt. >100 degrees C with aq. acid as above, then contacting it with a substantially anhydrous base from hydroxides and carbonates of Na and K, then heating at 100-150 degrees C to form iso alpha-acids salts, then extracting with water at pH 8-9.5 and sepg. The product is used in beer making. The acid treatment results in higher and more constant yields.

Title: Plate spring vibrator loco absolute gas pressure meter - maintains constant amplitude or current and measures the other
Inventor: WILLWEBER ROLF
IPC: G01L9/00
Filed: 1979-02-12
Abstract: Device is described for measuring small absolute gas press. in the measurement range 0 to 1.7 Torr. A plate spring vibrator vibrates with a very small air gap inside a vacuum sealed capsule axially w.r.t. the capsule. The gas pressure can be measured in three ways. The first method involves maintaining a constant vibrator excitation current and measuring the pressure dependent vibration amplitude. The second method involves maintaining a constant amplitude of vibration and measuring the pressure dependent excitation current required to do so. The third method also entails maintaining a constant vibration amplitude and measuring the gas pressure dependent acoustic pressure using a microphone. The first method requires less costly electronic circuitry than the other two.

Title: Couch grass herbicide - contg. tri:chloroacetic acid, maleic hydrazide and sodium 2,2,-di:chloropropionate
Inventor: ROEMER HANS WOLFGANG
IPC: A01N43/58
Filed: 1979-02-21
Abstract: New agents for combatting couch grass contain 5-25 wt.% trichloroacetic acid (TCA), 5-30 wt.% maleic hydrazide (MH) and 20-40 wt.% 2,2-dichloropropionic acid Na salt (DCP-Na), opt. together with usual carriers or diluents. Rate of application is 25-35 kg of the combination per hectare, dispersed in 400-500 l. water. Application is carried out in spring by spraying onto the leaves of the couch grass in stubble fields. Absorption takes place over about 3 weeks, after which ploughing can be done in the usul way. Effect of the combination of TCA, MH and DCP-Na is greater than would be expected from the activities of the individual components, but the combination is without injurious effects on the crop palnts. Combination is suitable for use on all soil types, including moor soils.

Title: Straightening unit for drawn round metal bars - has line of dies alternately contacting opposite sides of bar rotated by rotary end dies
Inventor: BOCK ERWIN
IPC: B21D3/06
Filed: 1979-09-18
Abstract: Drawn round metal bars (1) are straightened by passing them through a line of straightening dies. The dies (6,7) are mounted in roller bearings so that they are free to rotate. The dies are so arranged that alternate dies are in contact with opposite sides of the bar. The bar is rotated about its longitudinal axis by rotating discs (2,3) at each end of the line of dies. The bar is subjected to forces which create a stress greater than the yield stress of the material during the straightening process. This method does not cause any change in nominal dimensions of the bar.

Title: Gyrocompass eliminates lengthy azimuth deflections - using rotor support mounted on floating sphere and rotating about gimbal axis
Inventor: CHRISTOPH PETER DR
IPC: G01C19/38
Filed: 1980-04-02
Abstract: A gyroscopic compass has a single neutrally suspended gyro rotor held in the horizontal plane by a torque generated by displacing a mass on the gyro rotor support in the direction of the rotor axis. It eliminates the problem of unknown long-term deflections in azimuth caused by unknown centre of gravity displacement associated with oil displacement mass arrangements and the extreme balancing requirements for different degrees of freedom. The rotor support, which carries the rotor bearing is mounted in a floating sphere so as to rotate about a gimbal axis. The gimbal axis intersects the rotor axis at the centre point of the rotor support and the parts resting on it. These parts include the displacement mass, its corresp. motor and a motor control accelerometer measuring along the rotor axis.
Patent DE-3014099-A1 (DE)
Inventor: STUMPF FRIEDRICH DIPL PHYS
IPC: G03B17/24
Filed: 1980-04-12
Abstract: A motion picture camera has a rotary shutter driven by a DC motor which is supplied from a battery. The camera also has an arrangement for making light markings for identification purposes on the film in the camera. This arrangement includes a light-emitting diode and a capacitor which is charged by the battery and discharges across the diode. The electrical circuitry is such that the capacitor is connected to the battery only when the motor is disconnected therefrom; inversely, when the motor is to be connected to the battery in order to operate the shutter (and also to advance the film), the capacitor is first disconnected from the battery before the motor is connected to it and then discharges across the diode. The circuit also suppresses afterglowing of the diode.
