Patent DE-3832099-A1 (DE)
Inventor: VESEI LASZLO DIPL ING
IPC: A01B23/06
Filed: 1988-09-21
Abstract: Such discs are normally made in one-piece and comprise an outer circumference which is chamfered to provide a cutting-edge and a central opening mounting them in a row onto the axis of the harrow. During ploughing work the cutting edges of the discs progressively wear away until the discs can no longer be used and must be replaced, leaving 80-85% of the original disc unused and wasted. The object of the invention is to provide such a disc in which the complete disc does not need to be replaced when worn away, and replacement can be effected quickly and easily. According to the invention such a disc consists of an inner carrier part (1) and an outer wear-ring (2) which is mounted on the outer circumference of the inner carrier part, preferably by screws (3) or rivets. The outer wear-ring may be made of one-piece, or of a number of segments. <IMAGE>

Title: Multitherm-temperature-time-controller-dip probes
Inventor: SACHSE RUDOLF DIPL ING
IPC: A23L3/16
Filed: 1988-10-04
Abstract: The multitherm-temperature-time (= Tt)-controller-dip probe invention relates to microelectronic measuring devices and control devices as well as to methods for energy supply and/or energy dissipation corresponding to product-optimal specifications and signal transmitters. The objects consist in controlling cooling units, heating units and/or hygiene-ensuring units as well as protective packing devices in the ranges from -35@C to 330@C and with set times between 30 seconds and 30 hours in such a way that temperature effects and time effects which are optimal with respect to reaction kinetics in each process phase are implemented product-specifically and with little operator attention on the outer layers and in the core layers of materials, devices and products which are being treated. According to the invention, these objects are achieved in that, for the control of the energy supply and/or energy dissipation corresponding to the specifications, measured signals are used which come from sensors, of which at least one is wrapped on the outside and others are wrapped in product-adequate inhibiting layers for the distribution of energy quanta. By means of a microcomputer, the following are guided according to program input and are actuated by means of power-electronic components: signal transmitters, drives for valves, switches, pumps.

Title: Microprocessor system with bus line system which is secure from interference
Inventor: NIESSNER GERHARD
IPC: G06F13/42
Filed: 1989-01-05
Abstract: Between the n-position address/data bus outputs and inputs (AD0 to AD7) of a microprocessor (MP), and a peripheral device (PE) which is equipped with a memory, line driver and intermediate memory devices (LTE, ZP), which can be controlled bidirectionally and switched to effective, are inserted in the bus connecting lines (BL). These are activated and switched to effective by control signals, which are formed in a logic device (LGE), a decoding device (DEC) and the microprocessor (MP). Insertion of the line driver devices (LTE) makes it possible to lengthen the bus lines. The intermediate memories (ZP) and line driver devices are controlled by the logic device (LGE), the decoding device (DEC) and the microprocessor (MP), in such a way that the bus lines (BL) are only activated, and a bus access cycle is only controlled, when data is to be interrogated by the microprocessor from the memory of the peripheral device (DEI), or stored in it. <IMAGE>

Title: Hydrostatic supporting bearing
Inventor: ABTHOFF JOERG DR ING
IPC: F16C32/06
Filed: 1989-03-21
Abstract: A hydrostatic supporting bearing is described, consisting of a supporting body and a counter-body, with a recess in the supporting body which is filled with a flow medium and into which there is inserted an annular body which is guided by guiding surfaces with respect to the supporting body and is pushed by the pressurised flow medium towards the counter-body and whose annular sliding surface forms a freely adjusting bearing gap together with the counter-body sliding surface. In order to save on the supply of pressurised flow medium in this supporting bearing and hence the pressure-generating pump, provision is made for a seal, which prevents the escape of flow medium through the guiding surfaces, and a collar as part of the annular body, which projects radially outwards beyond the recess without support on the supporting body and forms at least a part of the annular sliding surface.
