Patent DE-3371400-D1 (DE)
Title: Orbital speed reducer with compensation coupling
Inventor: PIERRAT MICHEL A
IPC: F16H1/48
Filed: 1983-02-23
Granted: 1987-06-11
Abstract: A speed reducer having an orbitally driven rotor, mounted for free rotation on a rotor drive wheel driven along a rotary path by a drive shaft, has a perimeter defined by an epitrochoidal curve that simultaneously engages each of a series of rollers arranged in a circle around the rotor, the number of lobes on the rotor being one less than the number of surrounding rollers. Rotation of the drive shaft causes the rotor to move orbitally and to rotate with a speed reduction equal to the reciprocal of the number of lobes.The rotor drive wheel is driven by a compensation coupler that prevents radial forces of the rotor and the rotor drive wheel, such as may be generated as a result of inaccuracies in machining, temperature changes, etc., from being transmitted to the drive shaft where they could be translated into large forces. With the present arrangement, the drive shaft provides only a rotary thrust on the rotor drive wheel and is shielded from reaction movements of the rotor and rotor drive wheel.The rotor drive wheel is driven along an orbital path by a variable-length crank arm that extends into a radial opening in the rotor drive wheel and makes sliding engagement with opposite faces of the radial opening. The driving surfaces that engage the faces of the radial opening form, in a plane perpendicular to the axis of the drive shaft, arcs of a circle equal in diameter to the width of the radial opening. The radial opening is long enough to permit the rotor drive wheel and the rotor to follow the requisite orbital path. The crank arm includes an expansion slot that divides it into two fingers that embrace opposite sides of the radial opening. For smaller units, the spring quality of the fingers is relied upon to maintain firm engagement between the fingers and the faces of the slot. In larger units, an adjustment screw permits changing the spacing between the fingers to precisely fit the width of the crank arm to the width of the radial opening. In either case, the only radial forces on the drive shaft are those generated by the torque of the drive shaft.

Title: An image receptor and method for producing an opaque print thereon
Inventor: KUEHNLE MANFRED R
IPC: G03G13/22
Filed: 1983-09-23
Granted: 1988-01-21
Abstract: An opaque reflective print copy is produced by transferring via heat and pressure, an electrophotographically formed toner image to a presoftened transparent thermoplastic thin layer carried bonded to an opaque substrate. The print is formed of at least one generally planar toner image layer embedded in the plastic layer near the outer surface thereof whereby light illuminating the print enters the thin layer and is reflected from the interface between said layer and said substrate, passing through the toner particles as well as being reflected from the toner particles themselves, whereby to provide an image having greater depth intensity and contrast than can be obtained using silver halide photographic film, all without distortion of the image, loss in density or loss in resolution. The substrate may have smooth or roughened surface, and may be selected from plain or coated paper, metal, stone, stretchable and/or inflatable media as well as irregularly shaped objects. Successive toner images may be applied superimposed one on the other in layers and in registry by softening the thermoplastic layer after transfer thereto of one toner image and applying the next toner image thereto. The intermediate heating embeds the toner image and readies the receptor to receive the next toner image.

Inventor: AICHELMANN JR
IPC: G06F12/16
Filed: 1983-05-27
Granted: 1990-01-04
Abstract: A method of operating a large fault tolerant semiconductor memory is described which increases the probability that data words read from memory will not contain uncorrectable errors. The method involves storing a data word at a location in memory that may have a defect in either the true form or compliment form depending on which form will be perceived by an error correcting system as containing no errors on readout. Each data word transferred to memory is tested to see if one form or the other results in an error on readout. If the true form results in an error indication, the data portion of the word is stored in compliment form and the check byte stored in true form. On a subsequent transfer of the word from memory, the ECC system indicates an apparent uncorrectable error resulting from both portions of the word being stored in a different form while in fact the uncorrectable error indication is a signal that the data portion was stored in compliment form. The arrangement allows the ECC system to correct soft or intermittant type errors even though they occur at a memory address having one defect.

Abstract: o A brake control system for a multiple unit train of mixed motor cars and trailer cars - of the type usually to be found operating as metro or mass transit trains - and in which the motor cars have dynamic brakes operation of which is blended with, but given preference over, the friction brakes of all units. A brake demand signal calling for a given level of train retardation is weighted on each vehicle, according to the load of the vehicle, and the level of dynamic braking effort invoked on each motor car is limited in accordance with a maximum adhesion level calculated in proportion to the measured load of that car. In a modified arrangement the adhesion level is calculated in accordance with the load of the lightest loaded motor car. Signals representing the amount of dynamic brake effort achieved by each motor car is supplied to a trailer car and subtracted from the load weighted braking effort for the trailer car and the result used to actuate the friction brakes of the trailer.
