Patent DE-2435106-A1 (DE)
Title: Motor-mower device saving energy and increasing performance - rotational axis of cutter-blades angled at less than right angle
Inventor: ALAMOUTI NASSER DR
IPC: A01D34/63
Filed: 1974-07-22
Abstract: A mower usually has blades rotating parallel to the ground's surface. The energy lost through friction on the grass already cut, by grass collecting in the centre of rotation, and by stalks being cut through several times, can be conserved by altering the angle of the blades from the usual one of right angles to the ground. If the blades are positioned at an angle of less than ninety degrees to the ground, only the outer ends touch the grass in the front cutting semi-circle and the friction with the already mown grass is reduced to a minimum. The desired slanting angle of the cutter blades can be produced by, for example, a pair of wheels with different diameter.

Title: Photoelectronic testing of filled bottles - in bottle filling plants, involves comparing ray deflection by full and incompletely filled bottle
Inventor: MUELLER PAOLO
IPC: G01N33/00
Filed: 1974-08-06
Abstract: The difference between ray deflection by a properly filled, and insufficiently filled bottle serves as the criterion for the latter rejection; equipment carrying out the method comprises at least one test light beam generator and a corresponding light reciever which is coupled with a bottle rejecting device; A device for generating a light beam directs its beam onto a non-cylindrical bottle part near the neck. The beam of light may be oblique or parallel to the liquid level. The light receiver is able to determine the difference between bubble free drink mixture and foam. Several light beam generators and light receivers may be used for thorough testing of the bottle and its contents.

Title: Vertical shaft furnace for calcining lime - which is fitted with tiers of peripheral burners and bottom axial burner
IPC: C04B2/12
Filed: 1974-12-24
Abstract: Shaft furnaces for calcining lime, employ liq. or gaseous fuels which are sprayed periodically into several zones located one above the other, and with pauses between the spraying periods. The spraying sequence is arranged so that the pauses coincide periodically and, during the coincident pauses, liq. or gaseous fuel is fed upwards from beneath the lowest zone. The zones pref. contain horizontal burners, an additional burner, directed upwards, being located in the furnace below the bottom zone and fitted with a baffle cone. Normally, when peripheral burners are used, the shaft dia. is restricted to 2.5-3 m, because if larger dias. are used the central zone of the shaft is not properly heated. By using a central vertical burner, the invention permits the use of larger shaft dias.

Title: Ferrite parts strength testing method - uses electromagnetic eddy currents in round or strip shaped parts
Inventor: DRECHSLER GUIDO
IPC: G01R33/12
Filed: 1975-12-15
Abstract: The eddy current method is combined with a known comparison method. One or two parts with the same geometry and with the same or nearly the same pretreatment, but annealed, are placed for comparison of identity in one or two coil systems (4, 5) or placed for saturation on or in an electro-magnet yoke, so that the permeability of the workpiece practically disappears, owing to saturation. The system eliminates existing differences of permeability of workpieces so that remaining differences point to properties which cannot be detected in the annealed state, and the property of interest esp. the mechanical strength, can be determined.

Title: Grip assistance for vehicles on icy roads - has heated air jets supplied with excess engine heat and directed in front of wheels
Inventor: MUEHLEISEN HANS
IPC: B60B39/00
Filed: 1976-01-20

Inventor: GRUZLEWSKI HEINZ
IPC: G01R31/28
Filed: 1976-02-27
Abstract: The fault-finding test jig for colour T.V. servicing comprises a fault simulator using an identical type of set to that under test. Each individual functional module (integrated circuit etc.) of the set under test is also fitted in the simulator (19-24). Each of these modules or groups of modules is wired to a selector and light-emitting diode mimic display panel (26, 27) associated with the control monitor (18).
