Title: Blow moulding of thermoplastic pipe bendsand elbows
IPC: B29C49/04
Filed: 1971-06-01
Abstract: A continuously formed thermoplastic resin tube of predetermined wall thinness is cut into predetermined lengths by shears or hot wires, each of which are lowered and suspended in a multipart blow mould and thereafter bent upwards by a dish-shaped pneumatically operated mould section as this closes off the blow mould and pinches off and seals the ends of the tube section, and finally the pre-form tube bend is expanded by compressed air against all the inner walls of the blow mould and after cooling the solidified pipe bend is released by opening the mould. This process is used to produce pipes for e.g. wash basins and is rapid with minimal material wastage.

Patent DE-2329279-A1 (DE)
Title: Biochemical sewage treatment using oxygen - at feed rate controlled by oxygen consumption of microorganisms
Inventor: KLEIN HANS-ULRICH
IPC: C02F3/04
Filed: 1973-06-08
Abstract: In a biochemical treatment plant for sewage, oxygen is introduced into a scrubber tank filled with a packing of lava slag, coke or brick granules. The oxygen feed rate is automatically controlled by a float switch as a function of the oxygen consumption of the microorganisms. The rise in acidity is compensated by a controlled admixture of alkaline solns. The admission of pure oxygen speeds up the reactions so that the plant can be smaller and its operating costs lower. This plant can deal both with fluctuations in the throughput and in the degree of contamination of the sewage.

Title: Detection of faulty capacitors - uses measuring of current noise in capacitor at low frequency with subsequent evaluation
Inventor: HEINRICH GOTTLOB
IPC: G01R31/18
Filed: 1973-09-13
Abstract: The process is intended for detection of faults undetectable by current electric measuring which could lead to later failures. The current noise of the capacitor is measured at a relatively low frequency, and the capacitor is then evaluated. A 50 Hz a.c. voltage may be applied to the capacitor and the current noise is measured at a frequency above 1 kHz. The measuring may be carried out between two and 20 kHz, with a bandwidth of 1 kHz. The tested capacitor may be connected in series with a resistor to a 50 Hz test voltage source. At the voltage input the capacitor is in parallel with the capacitor-resistor series circuit. The noise voltage is collected from the resistor and applied to a measuring device through an amplifier and high pass filter.

Title: Clamp for vehicle supply lines - with clips slid onto fitting strip for universal mounting
Inventor: GERBRACHT KARL
IPC: F16L3/22
Filed: 1974-01-24
Abstract: The supply pipes etc. for a vehicle are positioned inside the U-shaped chasis members for protection. The use of flexible plastic pipes gives a simple, economic construction but raises problems for mounting clips. In order to reduce the number of fitting holes to a min. a special mounting strip is moulded with a longitudinal slot, as well as two fitting holes. C-shaped clips are slid into the slot in the required order for the pipe assembly while the strip is secured to the chassis frame by only two bolts. The pipes are clipped into the C-clips for rapid assembly and are held securely. Clips and strip are of a strong plastic material with good temp. and impact properties.
Patent DE-2403556-A1 (DE)
Title: Overrunning trailer brake mechanism - has wedge-operated roller between chamfered brake shoe ends
Inventor: PEITZ SEN JOSEF
IPC: B60T7/20
Filed: 1974-01-25
Abstract: Without the use of a brake-override arrangement the trailer can be moved backwards by the reversing car without the brake shoes becoming effective. The brake shoe ends opposite the operating mechanism are chamfered to an angle widening towards the operating end. Between this angle a roller is placed and kept in place only by the pressure of a wedge sliding in a guide. The relevant actuating factor is the sense of rotation of the brake. The roller element revolves slightly along one side of the chamfer and due to the action of the wedge the brake shoes are expanded resulting in braking action or no braking action during reversing.
