Title: Tractor tractive effort control mechanism - regulates effort dependent on amount transmitted by front and rear wheels
Inventor: MEINCKE KLAUS
IPC: A01B63/112
Filed: 1979-03-15
Abstract: The tractive effort control mechanism is for the hydraulic lift of a farm tractor, particularly one with all-wheel drive, and having a pendulum-mounted front axle. The resistance encountered by a mounted plough acts on a spring measurement device working with a sensor. The latter generates electrical signals corresponding to movement of the device and which adjust the hydraulic lift control valve. Effort is regulated dependent on the amount by which the effort transmitted by the front (1) and rear (2) wheels deviates from the ideal value, and typically by the amount for which the front axle is relieved of load.

Title: Electromagnetic induction therapy - using single solenoid pulse generator and delay line, with pulse output fed to adder amplifier amplifier
Inventor: LUDWIG WOLFGANG DIPL PHYS DR R
IPC: A61N2/04
Filed: 1979-04-04
Abstract: The single solenoid for electro-magnetic induction therapy replaces the two separate solenoids, where one solenoids, where one solenoid was placed close to the brain and the other near the member to be treated. It was discovered that the magnetic induction was still effective with both coils placed close to the head of the patient and this led to the use of a single solenoid. The nerve impulse delay between organ and brain is reproduced by introducing a delay line (5). The output of the pulse generator (4) and the delayed pulse are fed separately to an adder amplifier or, alternately, trigger a second pulse generator, the two currents energising the single solenoid (7).

Patent DE-2930514-A1 (DE)
Title: Flexible sealing ring for rotary shaft - has lip which fits neck between different shaft diameters
Inventor: KRAEMER HERMANN
IPC: F16J15/3216
Filed: 1979-07-27
Abstract: A rotating shaft increases in dia. from a section in a higher pressure region to a section in a lower pressure region, giving a curved transitional portion. Against this portion abuts the corresp. shaped resilient lip of a sealing ring. The lip need only fully contact the transitional portion when subjected to pressure. The main body of the sealing ring may be gripped between two resilient backing rings. The sealing ring is for the shafts of pumps, fans, compressors, mixers, etc., and since the contact area between shaft and ring is greater than with known rings, the resultant wear is less. The sealing lip is unlikely to deflect into its reversed position, even under sudden pressure increases.

Patent DE-2947679-A1 (DE)
Title: Fabric cladding process - has cladding components applied separately but directly after each other
IPC: D06B19/00
Filed: 1979-11-27
Abstract: Where the fabric cladding material is composed of two components, they are kept apart from each other, but applied in rapid succession directly after each other to the material. The components of the cladding material are poured so that each develops a fluid film which falls on to the fabric. In the case of a backing for carpetings, a polyurethane foam is formed from separated polyol and isocyanate which are applied as equal films and then react together to give the foam. The polyol bath is augmented by filling material or a heavy oil to give the fluid film after they have been mixed together, and the polyol is applied to the fabric first. Alternatively, the cladding components can be applied in only one film flow. The process allows a cladding to be applied to fabrics moving at high speeds, without loss of cladding material outside the fabric width.

Title: Pulse-Doppler-radar appts. - has digital integration circuitry for video signals and threshold circuit for suppressing noise signals
Inventor: GUENTHER HEINZDIETER
IPC: G01S13/524
Filed: 1980-02-28
Abstract: The pulse-Doppler-radar appts. uses the analogue echo signals received, plus the receiver noise, and digitalises them in an analogue-digital converter (ADW) feeding them to a doppler filter (DF). The signals emanating from the moving target are the only ones at the output side of the filter (DF) and these are fed into a video rectifier (VG). These rectified signals are then integrated in an integrating circuit (NI), matched to the antenna function, in order to raise the signal-to-noise ratio. A threshold circuit (WS), discriminates them as to whether the output signals from the integrator (NI) should be suppressed as a noise signal, or fed to a visual display unit as signals received from a target. This circuitry suppresses any permanent echo and improves the signal-to-noise ratio, by its method of signal processing.
