Patent DE-3034199-A1 (DE)
Title: Automobile speed regulating device maintaining correct vehicle spacing - monitors steering wheel movement to disconnect spacing control around bends
Inventor: ACKERMANN FRITZ DIPL PHYS
IPC: B60K31/00
Filed: 1980-09-11
Abstract: The speed regulating device adjusts the speed in dependence on the distance from the preceding vehicle. It also monitors the angular movement of the steering wheel and responds to movement through an angle outside a defined range to disconnect the vehicle spacing control until the steering wheel is brought back into the normal position. Pref. the vehicle spacing control is disconnected when the steering wheel is moved through an angle of more than 10 degs. in either sense. The cut-out device prevents the onboard radar responding to objects at the side of the road when the vehicle is negotiating a sharp bend and the preceding vehicle falls out of sight.

Title: Solid material transport speed measurement - using electrodes in pipe walls for conductivity measurement and obtaining cross-correlation
Inventor: KAZANSKIJ IGOR DR
IPC: G01P5/08
Filed: 1980-10-15
Abstract: The system measures the speed of solid material being hydraulically transported in pipelines. The system incorporates one or more sensors installed in the walls of the pipe. Typically these sensors may be electrodes connected in pairs to enable measurement of the conductivity between them. The electrodes may be connected into a Wheatstone bridge circuit. The measured conductivity fluctuates as the solid particles move along; several electrodes spaced along the length of the pipe may be used, and the cross correlation between the signals may be noted to obtain a reading for the speed of flow.

Title: Transformer iron core with improved cooling characteristics - is laminated spirally wound core with slots around outer periphery to increase cooling surface
Inventor: BARTL KARL
IPC: H01F27/245

Title: Means for preventing belts in belt-conveyor systems from being slit longitudinally
Inventor: TUESCHEN ALFRED
IPC: B65G43/02
Filed: 1981-03-21
Abstract: The invention relates to a device for preventing one or more conveyor belts in a belt-conveyor system from being slit longitudinally by objects which can be jammed at the charging points and/or transfer points for the goods to be conveyed. The device comprises in each case a monitoring member for each charging point and/or transfer point, which member transfers to a comparison unit characteristic values for the movement of the goods to be conveyed, e.g. the conveying rate, or for the loading of the drive, e.g. the motor power. Said comparison unit compares this value with a previously received characteristic value and, in the event of a deviation which exceeds a predetermined deviation, gives a switch-off command to the associated drive motor. <IMAGE>

Inventor: SCHMIDT SABINE DIPL ING
IPC: C04B35/80
Filed: 1981-07-01
Abstract: Heat insulation mixtures are employed both in the form of compacts and in the form of loose ballast. Heat insulating materials which contain an opacifier and thereby are impervious to the radiation which occurs possess extraordinarily good insulating activity. By using quartz powder of a specific particle size spectrum as opacifier, there can be attained optimal insulating properties preferred at high temperatures of use. This type of heat insulating material can be produced by mixing the individual components. It can contain known filler components and binders.

Title: Method and system for multizone imaging of objects
Inventor: ZIMAN YAN LVOVICH
IPC: G02B27/46
Filed: 1981-08-25
Abstract: The method for multizone imaging of objects consists in converting the object image into an image of the spatial frequency spectrum of the object, in which the information on the spatial object structure is contained. In this case, a selection is made in this spectrum of at least one zone whose radiative flux is integrated in real time to generate video signals which correspond to the relevant object image. In the multizone system, a space/time modulator (14) and an optical element (15) for converting the object image into an image of the spatial frequency spectrum are arranged in series upstream of the device (16) for the purpose of splitting up the spectrum. <IMAGE>

Title: Lever clamp
Inventor: KLIMACH HORST ING GRAD
IPC: B25B5/08
Filed: 1981-09-17
Abstract: Lever clamp with a guide rail, a first clamping strap fixed relative to the guide rail, and a sliding strap which is displaceably guided on the guide rail and can be secured to the latter by tilting. A pressure piece is held on the sliding strap in such a way as to be movable in the clamping direction and a clamping lever is linked to the sliding strap. The clamping lever has an eccentric for moving the pressure piece in the direction of the fixed strap and can be fixed by a releasable locking mechanism. Such a lever clamp with considerable functionability can be manufactured relatively cheaply when the sliding strap and clamping lever have stamped sheet-metal inserts which serve to absorb force and reduce wear and are each embedded in a cast part.

Title: Apparatus for conveying coal in underground mining operations
Inventor: PAURAT FRIEDRICH WILHELM
IPC: B65G19/20
Filed: 1981-01-24
Abstract: The invention starts from an apparatus for conveying coal and similar material to be conveyed in underground mining operations. In particular, the apparatus is a face conveying apparatus. In its basic construction, the apparatus consists of a conveyor trough with conveyor-trough base and conveyor-trough side walls, a means of moving the material to be conveyed, and a drive device. The material to be conveyed and the means of moving the material to be conveyed slide over the conveyor-trough base. The means of moving the material to be conveyed is run with a forward strand and a return strand in a revolving manner over deflection devices and is driven by at least one toothed drive drum of the drive device. In order to avoid a means of moving the material to be conveyed which has heavy haulage chains and scrapers and in order to also avoid the steel-on-steel friction caused by this, the means of moving the material to be conveyed is designed as a conveyor net. The conveyor net has net sections transmitting tensile force, net-section connecting elements, and conveyor-net mesh permitting penetration and/or passage of portions of the material to be conveyed. The conveyor net is made of a friction-reducing plastic, in particular an aromatic polyamide.

They have good biodegradability. The use concentrations are between 0.1 and 10 (1-3)% by weight, relative to the mineral oil base.
