Title: High voltage generator with insulating cover - has concentric layers of dielectric with different characteristics in pistol grip housing
Inventor: BRAUN FRANZ DIPL ING
IPC: B05B5/053
Filed: 1975-07-25
Abstract: The generator for high voltages has an insulating cover (3, 7) which consists of two contiguous insulating layers with different constants, of which the outer layer has the larger mechanical strength. The layers are concentric and are mounted in a pistol grip type of assembly (9). The inner layer is of tubular form, and a high voltage cascade is developed within it (5). The material of the inner layer is semi-platic. A more elaborate construction uses three layers of material in the inner core, all having different dielectric constants. The design is intended to maximise the generation of high voltages within the minimum volume and weight of generator.

Title: Vehicle operating parameters dynamic measurement - involves roller test stand with flywheel on which vehicle wheels can roll
Inventor: DINKELACKER WALTER DIPL PHYS
IPC: G01L3/24
Filed: 1975-09-11
Abstract: The measured parameter is esp. the power of the vehicle i.c. engine. A flywheel can be connected to at least one of the rollers, and is accelerated by the engine through the vehicle wheels. When the engine is unclutched, the flywheel drives the vehicle wheels and is decelerated. Power delivered to the vehicle wheels is determined during acceleration from the flywheel speed and its rate of change and from the moment of inertia of the test stand rotating components and possibly of the rotating vehicle parts. Power dissipation is determined during deceleration, and the i.c. engine power is calculated from the sum of the two values. A correction value is taken into consideration when the wheel power and dissipation power are determined.

Title: Acid gp. contg. acrylonitrile (co)polymers prepn. - using pulsing charging of monomers
Inventor: ENGELHARD HELMUT DR
IPC: C08F20/44
Filed: 1976-04-29
Abstract: Acid gp. contg. acrylonitrile (co)polymers (AP) are prepd. by continuous suspension polymerisation using a redox catalyst system at pH 1.5-5.0 and a reaction temp. 20-70 degrees C. The monomers are charged in periodically repeating time intervals during defined time, into a reaction vessel provided with an outlet (pulsing monomer charging). The individual time intervals amt. to 1.5 to 40 times the charging time. The redox system and opt. further polymerisation aids are charged steadily and in a constant amt. over the total polymerisation time. Pref. is not >15 wt.% of comonomers are incorporated e.g. olefinic un-satd. cpds. Pref. redox system is K2S2O8/Na2S2O5 (1:2 to 1:10) and pref. amt. of catalyst system = 2-7 wt.% w.r.t. the total monomer %. Pref. AP have a K value = 60-110 as required for fibre prodn., a U value-2-14 (U = Mv/Mn - 1; Mv = viscometric, Mn = osmometric mol. wt.) and a terminal acid gp. content = 80 pref 90-130 m equiv./kg of polymer. The pulsing monomer charging results in a higher % of acid gps. in the polymer, compared with a steady charging process without a lowering of the K value. The polymers may be used in fibre prodn. and have improved dyeability to basic dyestuffs.

IPC: D06P1/92
Filed: 1976-05-14
Abstract: Monoazo dispersion dye of formula (I) are modified to have lattice plane sepns. of 10.26 angstroms, 6.48 angstroms and 4.01 angstroms.

Used for dyeing of synthetic and semi-synthetic fibres, esp. polyesters, from organic solvents immiscible with water, opt. contg. small amounts of water, at up to 140 degrees C by exhaust processes. Formation of dye deposits in the bath, causing uneven dyeing and poor fastness to rubbing, are reduced. Thermal stability of the dye concentrates is improved, e.g. after 8h. storage at 50-80 degrees C their dispersion on dilution with solvents, esp. tetrachloroethylene is unchanged Crystal structure remains uncharged under usual dyeing conditions.

Title: Triggering circuit for polyphase static converter - produces triggering pulses by adding two phase shifted single phase voltages
Inventor: KOELLENSPERGER DIETER DIPL ING
IPC: H02M1/084
Filed: 1976-07-13
Abstract: The triggering circuit, for a polyphase static converter ensures that the conduction angle remains the same when the converter frequency is changed. This is achieved by limiting conduction angle changes to a given range. A first single-phase voltage (U3) obtained from the converter (6) input or output is added (15) to a second single-phase voltage (U1) derived in the same way as the first but shifted in phase. The sum is amplified (16) and passed to a zero detector (17) which produces a leading or trailing edge of a pulse each time the sum is zero. The pulses are amplified and used as triggering pulses for the converter.

Title: Air gun shooting competition target changing system - has strip carrying target markings unwound from on spool onto another
Inventor: GUENTHNER KONRAD
IPC: F41J1/10
Filed: 1976-11-09
