Title: Variable-speed transmission featuring circular translation
Inventor: ARNDT FRANZ MARTIN
IPC: F16H3/04
Filed: 1988-03-08
Abstract: The variable-speed transmission according to the invention featuring circular translation has, by virtue of the pairing of a relatively large internal gear wheel with a smaller external gear wheel and of an adjustable eccentric circular translation vector in the opposite direction situated on the same radius, the characteristics of a variable torque converter, this being achieved by means of gear wheels which are displaced in circular translation, forming an envelope as they roll, with standstill and reversal of the direction of rotation of the output shaft with a constant and unidirectional input speed of the input shaft. The adjustment of the circular translation can take place in a stationary condition by means of a spindle or in operation by means of known drive means, mechanically in a remote-controlled manner by means of a gear train, electrically by means of a servomotor or hydraulically by means of a hydraulic motor. The adjustment energy is supplied by the rotating input shaft.

Title: Method and device for invalidity operation for address conversion buffers in computer systems
Inventor: ARA MARI
IPC: G06F12/10
Filed: 1988-07-22
Abstract: The invention concerns a method and a device for invalidity operation for address conversion buffers in computer systems. A virtual computer system has an address conversion buffer memory (2), which converts a virtual address into a real address, and a register (1), to store an identification number (VMID) of a currently running virtual machine. In the address conversion buffer memory (2), a bit (V) to hold the VMID is provided, and also a comparison circuit (4, 5, 6), which compares the VMID held in the bit to the VMID supplied by the register (1), and generates a signal on the success of the conversion from a virtual address to a real address, on the basis of a comparison result which indicates agreement. A management table (9) holds data which give VMIDs which are used for definition of virtual machines which have been run until now, and if an invalidity command for the address conversion buffer memory (2) is issued during a run of a virtual machine, a control circuit (12) selects an unused VMID as the first information for defining a running virtual machine on the basis of the contents of the management table (9), and puts the selected VMID into the register (1). <IMAGE>

Patent DE-3900871-A1 (DE)
Inventor: KEIL MICHAEL DR
IPC: G02F1/1337
Filed: 1989-01-13
Abstract: In an LC display device comprising transparent electrodes 2a, 2b, orientation layers 3, the LC material is of the ferro-electric-smectic type and a linearly polarised light from source 5 is introduced laterally into a rear glass plate 1a and emerges via a light scattering layer 6 on a front glass plate 1b whereby the device is operable independent of ambient light or visual angle, has high resolution capability, short switching times and low temperature dependency. Incident light 8 is either totally internally reflected or refracted in dependence upon the absence or presence of an applied electric field which alters the refractive index at the interface between orientation layer 3 and LC material 4. Instead of a separate layer 6, the surface of plate 1b may be roughened to provide the scattering. The display may be of the segment or matrix type. <IMAGE>

Title: Atomising fine grain powder - by using inert gas which is preheated prior to blowing onto free falling melt stream
Inventor: GRAF WOLFRAM DR
IPC: B22F3/22
Filed: 1989-04-26
Abstract: Melt atomising to produce metal powder in which the atomising gas is an inert gas which is heated to 370-910 disc before being decompressed as it leaves spray nozzles directed towards a free falling melt stream. The gas is pref. heated to 450-650 deg.K. The kinetic energy of the gas is determined by the compression of the gas and this pre-pressure is essentially maintained constant during atomising. The hot gas atomising stage may be preceeded with a cold gas atomising stage to give a grain size distribution which is controlled by the durations of the two stages. USE/ADVANTAGE - Producing Fe-, Ni- and Co-based alloy powders to be used in spray casting. By controlling the temp. of the gas prior to decompression the size of powder produced can be controlled to give a fine grain size. The additional energy required is more than compensated for by the reduction of the average grain size produced. The higher the temp. the smaller is the grain size.
