Patent DE-2942529-A1 (DE)
Title: Hair growth enhancing appts. - has AC generator for short wave frequencies and radiator for alternating electromagnetic fields
IPC: A61N1/40
Filed: 1979-10-20
Abstract: The appts. generates periodical pulses of electromagnetic alternating fields of low energy in the short wave range, without any considerable thermal effect. The alternating fields can be particu. directed onto the hair base and the adjacent regions. They promote a formation of substances, enhancing the natural hair growth, as well as the blood circulation, and act directly on the hair root cells. The periodic pulses pref. have a frequency of 400 to 420Hz and a duration period of about 40 microsec. The alternating field has typically a frequency in the 11m band, or in the 7.5m band, i.e. 27MHz, or 40MHz. An energy of 0.5W is involved. Poles of a dipole aerial of the appts. form a simple, individually adjustable and effective coupling to the user's body.

Title: Auto-pneumatic gas blowout circuit breaker - has screen screening rated-current contacts from high-power contacts to reduce adverse interaction
Inventor: MITTELBACH GUENTER
IPC: H01H1/38
Filed: 1979-10-22
Abstract: When the breaker is closed, the current flows between the upper (2) and lower (3) connection plates through the rated current path (16, 17) and the power current path (4, 5) and through the cylinder (6) and high-current contact (11). If the drive rod (9) is moved in the breaker's out direction, both current paths are broken and an arc appears between the power contacts (4, 5). The pumps (6, 7) compresses the insulating gas (e.g. SF6) and expels it through the insulating nozzle (12) upwards towards the arc. The plasma is thereby pushed out of the nozzle (13) into the space between nozzle (13) and the fixed contact.

Title: Hormone assay on body fluids - using hormone receptor immobilised by pptn.
Inventor: GUMBOLDT GERHARDT DIPL CHEM DR
IPC: G01N33/74
Filed: 1979-10-27
Abstract: Determn. of a hormone in a body fluid is carried out by incubating an immobilised hormone receptor witha sample of the body fluid contg. a labelled hormone ligand and determining the amt. of hormone in known manner. The immobilised receptor is prepd. by (a) isolating a homogeneous aq. extract of the hormone receptor from the corresp. organ; (b) precipitating the receptor onto a carrier surface using a specific precipitant, and (c) removing adhering liq. from the surface. The method is esp. useful for determn. of oestrogen, testosterone, progesterone or thyroxine using radio-labelled ligands.

Title: Transferring dangerous liquids from storage container - to user container, by forming pressure difference between the two containers
Inventor: HEILENZ SIEGFRIED
IPC: F04F3/00
Filed: 1979-11-16
Abstract: Liqs. are transferred from a first bulk container to a second smaller user container by redn. of the air pressure in the second container to below atmospheric pressure, using a suction pipe connected to a water flow line. The first container is subject to atmospheric pressure which drives the liq. through a dipping pipe reacting close to the container base and via a communicating extension pipe into the second container. Should the second container be filled, due to inattention, the surplus liq. arriving is held in a catchment container on its way to the suction pipe system. For strong acids, alkalis, poisonous or inflammable liqs. esp. in chemical laboratories. The risk of accidents, or dissemination of unpleasant or dangerous fumes is avoided.

Title: Green bricks continuous conveyor system - has bricks arranged in spaced groups by two belts giving uninterrupted support to entire brick surface
Inventor: LINGL JUN HANS
IPC: B65G47/31
Filed: 1980-03-07
Abstract: The bricks or blocks are fed by a conveyor in a continuous row, in a spaced group for transfer to another conveyor.

Title: Press for producing beams or sheets from rods
IPC: B27M3/00
Filed: 1981-05-26
Abstract: In order to be able to work safely with a press for producing beams or sheets from individual glued-together or bonded-together rods, the lateral pressing device is situated on the side of the press facing away from the operator, and the counter-holder which receives the pressure of the lateral pressing device can be moved, and in particular slid, laterally approximately parallel to the plane of the sheet or the like to be produced into a release position. The counter-holder is composed of a plurality of transverse supports, to each of which is opposed a pressing support on the rear-side of the sheet or the like to be produced, all the pressing supports together forming the lateral pressing device. The rods rest on a supporting device which takes up the force of the end face pressing device. The latter, like the lateral pressing device, is essentially composed of a number of operating cylinders which corresponds to the number of transverse beams. A plurality of, especially four, such individual presses are advantageously combined to form a rotor press.
