Title: Independently excited HF vibrator for agricultural machines - has controlled vibration frequency and force level control
Inventor: ALISCH KLAUS DIETER
IPC: A01B11/00
Filed: 1975-08-01
Abstract: High frequency vibrations are produced by vibrators which are hydraulically driven from the tractor hydraulic unit, or by the hydraulic system on the machine itself. In the case of directed vibrations, they can point in or across the direction of travel or at right angles to the soil. The source of energy can be hydraulic, pneumatic, electric or a combustion engine. The high frequency vibration is transmitted to the implements such as plough-shares, tines, rollers or sole plates, used for cultivating the soil. The static load of the implements is replaced by a dynamic load. The soil can be cultivated appropriately by altering the frequency of vibrations, the force applied, and the direction of the vibrations, in order to loosen cracked earth, remove roots from the soil, break up large clumps and compact crumbly and wet soil.

Title: Correlator for contactless speed measurement - uses 3 sensors and correspondingly increased processing circuitry to reduce false correlation extremes
Inventor: MESCH FRANZ PROF DR ING
IPC: G01P3/80
Filed: 1975-10-03
Abstract: A correlator used in the contactless measurement of speed of moving objects, e.g. moving material on a roller system, using three measurement sensors, is designed to reduce the effect of false correlation function extremes. The method eliminates switching between coarse and fine circuits and special coarse circuit integral regulator and voltage-to-frequency conversion circuits. The sensors produce signals delayed w.r.t. each other by the time taken to traverse the distance between them. The three sensor signals are combined with three reference time signals provided from three shift registers and processed in differentiators and logic elements to form three separate correlation function signals which are added and input to an integral regulator. The regulator output is converted to a frequency corresp. to the traversing time which may be displayed using a digital counter.

Patent DE-2555551-A1 (DE)
Title: Refractory tube production
Inventor: HAGGERTY JOHN SCARSETH
IPC: B23K26/067
Filed: 1975-12-10
Abstract: In the mfr. of a refractory tube starting from a preformed tube of refractory material round which a concentrated heating zone is arranged by means of radiant energy of uniform intensity in such a way that a molten ring of uniform height is formed in, and is displaced along, the tube, the height being such that the surface tension forces and gravitational force hold the molten ring connected to the solid parts of the tube on each side thereof while the relative translatory motion between the refractory tube and the heating zone is regulated so as to displace the molten ring along the tube, (a) the radiant energy is formed by laser energy and the heating zone is formed by a series of laser beams of semicircular form uniformly distributed round the tube and each beam is focussed on the refractory tube to form the molten ring therein, and (b) the focussing is carried out in such a way that the energy density distribution of each beam is adjusted to give equal absorption of the laser energy round the whole surface of the tube within the molten ring. Enables the virtually full theoretical density to be achieved by eliminating any porosity introduced by e.g. impurities. Also permits, when appropriate, the production of a tube as a single crystal, so that limitations arising from the presence of grain boundaries, e.g. chain of atmosphere during treatment, are no longer of importance. The technique is particularly suitable for the production of Al2O3 envelopes for sodium halide-especially NaI- lamps, which operate at high pressure and temperature.
