Title: Weatherproof packaged straw bales - are wrapped in helically wound overlapping web of UV stabilised polyethylene
Inventor: SCHULZ HEINZ DR
IPC: A01F15/07
Filed: 1977-02-08
Abstract: Weatherproof wrapped circular straw bales are packaged following winding into a roll by helically winding an UV-stabilised polyethylene web 200-400 mm. wide and overlapping the coils by an amt. of 30-40 mm.

Title: Microcellular PTFE insert for venting nozzle - of moulding and/or vulcanising tool, facilitates removal of gases and vapours without risk of flash formation
Inventor: BECHER KLAUS
IPC: B29C33/10

Title: Water purificn. by air injected by wind power - from airscrew on mobile mast coupled direct to compressor
Inventor: KRAMPITZ JUERGEN ING GRAD
IPC: F03D15/10
Filed: 1978-06-01
Abstract: A quantity of oxygen which varies over a period of time is injected into water to purify the water. The energy of the wind is utilised and the feed of oxygen is made to pulsate. A screw with vanes is supported by a mast and supplies energy for driving a machine, esp. a compressor, which is connected to aerating lines laid in the water.

Title: Calculator indicating instantaneous speed of revolution - has microprocessor operating on time pulses counted during gating period
Inventor: STOCK HEINZ
IPC: G01P3/489
Filed: 1978-08-16
Abstract: A calculator indicates the instantaneous number of revolutions. It is easily mounted and gives precise measurement over the range 0.1 to 9,999 revolutions per minute. Only are initiator to measure the gating time has to be installed. A microprocessor uses a given formula to calculate the r.p.m. for the time pulses counted during this time. An inbuilt sliding decimal point permits an accurate reading at low revolutions. A quartz-controlled pulse generator supplies a frequency divider. these pulses are counted in an 8 digit binary code data counter. A potential change at the initiator - caused by a lug on the shaft passing it - is onverted to a pulse. The latter starts a command release counter pulsed by the frequency of the pulse generator.
