Title: Continuous polymerization method and apparatus
Inventor: IMAMURA TSUYOSHI
IPC: C08F2/00
Filed: 1992-01-31
Abstract: ABSTRACT OF THE DISCLOSURE    Polymer particles having a small particle diameter and a narrow particle diameter distribution are obtained by a continuous polymerization method which does not accompany an increase of cohering products attaching to an inner face of a reaction vessel and an air-bubble invasion and, in which stirring of a material solution for polymerization is easy. An emulsion polymerization reaction or a suspension polymerization reaction is carried out by supplying a material solution for polymerization continuously to a clearance between coaxial double cylinders, which have stretched toward a direction crossing a horizontal plane, from the end side of the cylinders, by rotating at least one of the double cylinders round the axis and thereby, causing Taylor vortices.  The polymer particles thus-formed are obtained by leading from the other end side of the double cylinders to an outside.

Inventor: CONSTEN FRITZ
IPC: H01J61/30
Filed: 1992-02-26
Abstract: To suppress undesired light peaks which arise at or close to the axis of symmetry of a single-ended electric discharge lamp, and projected away from the base of the lamp, a surface portion of the lamp adjacent the cap thereof, and near an exhaust tip is frosted or matted. Thus, lens effects due to accumulated glass adjacent the exhaust tip, and the curved dome-shaped portion at the end of the lamp, will no longer cause bundling of light rays which will be projected directly and provide axial light peaks or rings. Due to the matting or frosting, the transparency will be diffused and undesired light maxima due to bundled light rays are eliminated.

Abstract: Une orthèse pour le genou (10) comprend des maillons fémoraux et tibiaux (12a, 12b, 14a, 14b) et un mécanisme articulaire à quatre barres (18) au moyen duquel un côté latéral de l'un des maillons fémoraux (12a) est raccordé de façon pivotante à un côté latéral de l'un des maillons tibiaux (14a), et un mécanisme articulaire à quatre barres (20) au moyen duquel un côté médial de l'un des maillons fémoraux (12b) est raccordé de façon pivotante à un côté médial de l'un des maillons tibiaux (14b). Chacun des mécanismes articulaires comprend une plaque-pivot intérieure coussinée (23, 25) et une plaque-pivot extérieure (29), dont chaque extrémité est raccordée de façon pivotante en un point unique avec l'extrémité respective des maillons fémoraux et tibiaux. En outre, le coussinet situé sur la plaque-pivot intérieure du mécanisme articulaire du côté médial est porteur d'un coussinet du condyle fémoral à embout sphérique (24) au moyen duquel l'orthèse, en général, et le mécanisme articulaire, plus précisément, peuvent être positionnés adéquatement par rapport au genou du porteur. Les emplacements des points de pivotement (A, B, C, D) des plaques-pivots sur les maillons sont établis conformément à des paramètres qui sont conçus de manière à produire un mouvement multiaxial d'un point de référence (P) qui va obliger le tibia à glisser vers l'arrière par rapport au fémur selon une plage initiale de flexion du genou, à partir d'une position rectiligne de la jambe, pour ensuite pivoter par rapport à celle-ci le long d'une trajectoire arquée. Par ailleurs, l'angle entre les lignes imaginaires passant par les pivots de chaque plaque-pivot sera supérieur à une valeur minimale prédéterminée, ce qui conférera au mécanisme articulaire une force suffisante pour éviter qu'il se brise en cours d'usage lorsqu'une charge est imposée horizontalement en travers de l'articulation du genou.

Title: Bicycle mounting system
Inventor: DE SOETE ANDRE
IPC: B60R9/10
Filed: 1993-03-26
Abstract: UNITED STATES/CANADA                ABSTRACT OF THE DISCLOSURE           A bicycle mounting system has a base and a support to secure the pedals of a bicycle and a tongue for engagement with a trailer hitch. The support may be a hollow post or the like with vertical slots of different lengths. One slot, preferably shallower than the other,  receives the crank shaft of a bicycle, while  the  other  receives  the  pedal.  By  this construction,  the crank arm of the pedal  extends downward in the hollow support. A wedge is forced down against the pedal crank arm (which tends to extend outward) and locked into place to secure the pedal in the support. While this system adequately secures the bicycle, it is also desirable to prevent the entire bicycle  from  rotating  about  the  support,  which otherwise form a pivot. This may be accomplished by using fixed U-shaped supports that receive the wheels of the bicycle.

Title: Method of measuring the delay of ultrasound in the pulse reflection method
Inventor: STRIPF HELMUT
IPC: G01N29/38
Filed: 1991-12-12
Abstract: A delay time measurement method for ultrasound of the type wherein a testing head transmits an excitation pulse that is as close as possible to the shape of a shock wave and traverses a pretravel path until it reaches the object to be examined which has a front wall and a rear wall, with at least one reflected pulse being generated at its front wall as well as at its rear wall. To improve the above-mentioned type method so that delay time measurements for thickness determinations and abnormalities can be performed reliably even on rough surfaces and if reflected pulses are missing or falsified, a time window is determined for the recording of reflected pulses that follow the excitation pulse, within which window all successive reflected pulses are digitized. Then the reflected pulses that lie within the time window are digitally filtered and parametrized, and the filtered and parametrized reflected pulses are fed to a computer unit and are evaluated on the basis of variable criteria using a predetermined algorithm.
