Title: Measurement of distance from object to reference system - involves optical image correlator with at least one correlation structure
Inventor: SACK FRIEDRICH
IPC: G01S17/32
Filed: 1974-01-25
Abstract: A real image moves relatively to the image correlator. A structure is projected on the object within the field of vision of the correlator, whose azimuthal orientation is rigidly coupled with that of the correlation structure. Amplitude and fundamental wave of the photoelectric signals generated by the interaction of light fluxes are reflected from the object with the correlator, and are evaluated in order to obtain the distance to the object. A projector connected to the image correlator projects an image of the structure onto the tested object; this structure changes its shape only in accordance with a given spatial direction, and its shape and orientation correspond to the correlation structures.

Title: Active guiding mechanism for railway vehicle bogies - has compensating torque applying electromagnetic system on wheel set axle
Inventor: HERMANN PETER KONRAD PROF DR I
IPC: B61F5/38
Filed: 1974-03-25
Abstract: The active guide system provides additional torque on the wheel axles of the bogie to adjust the axle position relative to the symmetry axis of the rails. The sensors sense the instantaneous deviation of the bogie position from the symmetry position between the rails and the bogie. A rotating compensating magnetic system consists of a rotor held on the wheel axle and of the stator core of the compensating magnetic windings. Two such arrangements are used on an axle to provide equal and opposite torques on the wheel axle. The bogie relative deviation is sensed e.g. by inductive sensors in relation to the side faces of the rail head.

Title: Cigarette dispenser and lighter - current to ignition coil maintained after switching system opens
Inventor: FIELD MIKE
IPC: A24F15/10
Filed: 1974-04-09
Abstract: The cigarette dispenser and lighter has a mechanism operated by a button, which when pressed, activates the mechanism by which the cigarette is dispensed from the container, so that an electrical circuit is also operated to heat a coil against which the cigarette is held. Between the switch forming part of this electrical circuit, and the ignition coil is an electronic system for ensuring that the coil remains heated for a sufficient time after the switch has been opened. This switch is controlled by the button which activates the dispensing mechanism. The simple, one-handed operation is particularly suitable for use by car drivers etc.

Title: Monitoring lining wear in induction melting furnaces - by measuring change in voltage drop between each turn of the induction coil
Inventor: CHRISTOU SPYRIDION DIPL ING
IPC: H05B6/28
Filed: 1974-05-31
Abstract: The erosion, during use, of the lining of an induction melting or holding furnace contg. a conducting charge, is monitored by surrounding the position being monitored and the liq. charge with >=1 complete turn of an induction coil. The electromagnetic coupling, between the charge and the winding(s) round the position being monitored, is measured and compared with the value obtd. at an early stage in the life of the lining, or with a reference value. In the pref. process, the voltage drop between turns or groups of turns of the induction coil is measured and compared with a reference value. Indicates excessive erosion which might lead to a 'run-out' and damage to the furnace.
Patent DE-2432097-A1 (DE)
Title: Computer for digitisation of graphical information and drawings - adjusts scaling factor before transmission to reproduction machine
Inventor: KOEPPEL WILLY
IPC: G06K15/22
Filed: 1974-07-04
Abstract: A special purpose computer system provides a facility for the digitisation of graphical profiles relating to maps, drawings, articles etc., and permits reproduction with a change in scaling factor. Information from a drawing is digitised in an incremental "staircase" function form and is tied to specific co-ordinate reference positions. The information is then located in memory stages and any required changes in scaling for reproduction also entered. For example, a particular line may be either shifted along the 'y' axis or in regative direction. Defining a specific profile in terms of four quadrants, each quadrant may be reproduced with a different scaling factor. The digitised and modified data may be used to regulate step motors controlling the reproduction process.

IPC: C30B11/00
Filed: 1974-07-12
Abstract: In the prodn. of monocrystals, esp. AIIIBV monocrystals in the horizontal closed system, using a monocrystalline seed with definite crystallographic orientation, at reduced and elevated pressure, the seed crystal is fitted tightly in a boat having a flat wall, perpendicular to the axis of the boat, at the end next to the seed. The seed pref. is fitted in the boat so that the capillary gap between the seed and the wall of the boat is max. 300 mu. The boat pref. widens conically from this end for a certain length and then is of constant width, the conical part pref. being 10-100 mm long and increasing the cross-section of the seed up to a factor of 150. Method is esp. for the prodn. of GaAs and GaP monocrystals for luminescent diodes. The boat prevents the seed moving and gives a sharp monocrystalline solid/liquid phase boundary.
