Patent EP-0087743-A2 (EP)
Inventor: PIERRAT MICHEL A
IPC: F16H1/32
Filed: 1983-02-23
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.

Abstract: The present invention relates to a defrosting device, for a refrigerator with a number of cooling compartments, which only supplies heat to the evaporator in the fresh food compartment when strictly necessary, that is, when fast defrosting is required, whereas it provides for natural defrosting as long as this is sufficient. In a first arrangement, fast defrosting is performed each cooling cycle but only for part of the time the compressor is off and only after a given temperature threshold has been exceeded by the evaporator in the fresh food compartment or by the freezer. In a second arrangement, fast defrosting is only performed for one out of "n" number of cycles. Both these arrangements provide for energy saving as compared with known technology besides improving fast freezing performance by reducing food freezing time again as compared with known technology.

Abstract: Pyridine is prepared by ammoxidation (= reaction with oxygen or an oxygen-containing gas and ammonia, optionally in the presence of water vapour) of cyclopentadiene in the presence of a (precipitating) silica gel as a catalyst, which in particular has a lower Al2O3 and/or TiO2 content in regions close to the surface and a solid acid strength corresponding to a pKa of < +4.0. The silica gel catalyst should additionally have a surface area between about 200 and 800 m<2>/g and a pore volume between about 0.2 and 2.0 cm<3>/g; the reaction temperature is between about 200 and 400 DEG C. The process without exception gives pyridine selectivities between about 40 and 60 % and no pyridine homologues which are difficult to separate from the pyridine.

Abstract: @ A fluid deflecting assembly is disclosed primarily for use in an outlet port of an air conditioning unit for controlling the direction of an air flow discharged from the outlet port. The fluid deflecting assembly comprises a tubular body having a flow passage for passing a fluid flow axially therethrough, a nozzle body mounted on the tubular body and having a nozzle disposed downstream of the flow passage in a direction of the fluid flow, a restriction surface extending downstream of the flow passage in surrounding relation to the nozzle, and a guide wall surface extending downstream of the nozzle and flaring radially outwardly from the nozzle in surrounding relation thereto, and a bias flow shield disposed in the flow passage upstream of and radially outwardly of the nozzle for adjustably blocking a portion of a bias fluid flow directed by the restriction surface toward the nozzle. A fluid flow discharged out of the nozzle is defected by the bias fluid flow as modified by the bias flow shield so as to be attached to the guide wall surface. The discharged fluid flow can be deflected in desired three-dimensional directions through a wide angle by rotating and/or axially moving the bias flow shield.

Abstract: In a color imaging apparatus, an optical image is focused on a photoelectrical conversion target (6) of a color image pickup tube (1) through a color stripe filter having a plurality of successively arranged recurrent groups of different color stripes and converted to an electrostatic image which is scanned in rectangular raster form by an electron beam to generate a color-multiplexed video signal. Prior to normal imaging operation, the target is illuminated uniformly with light of a predetermined color to generate a reference "carrier". To reduce the amount of information on the nonlinearity of the beam deflection system, frequency variations of the reference carrier are detected by a frequency discriminator (21) and stored in a field memory (23) as a representation of the beam's nonlinear characteristic. During read mode, frequency and phase comparators (41, 48) detect frequency and phase differences between the output of the target (6) and an output signal from a variable frequency and phase oscillator (28, 29). The outputs of the comparators (41, 48) and the field memory are combined to control the oscillator to cause it to generate a reference carrier synchronized with the output of the target (6). A color demodulator (16-18) combines the outputs of the oscillator and the target to generate color difference signals.
