Patent CA-2195886-A1 (CA)
Title: Multicylinder boxer crankshaft assembly
Inventor: BARSKI WOJCIECH GRZEGORZ
IPC: F16C3/06
Filed: 1997-01-24
Abstract: In typical internal combustion engines and compressors, etc., it is known to have a piston, moving in a cylinder, connecting rod and a crankshaft, as a crankshaft system.      The gas and inertia forces press the piston against the cylinder side wall and produce bending stresses in the connecting rod.    With increased speed the effect of inertia forces may exceed this of gas forces. The second harmonic inertia force may cause bigger stresses than its first harmonic. This puts heavy demand on all components, posing limitations to speed and power.      Balancing is also difficult.

Abstract: La présente invention fait état d'un raccord novateur pour câbles coaxiaux. Le raccord comprend un corps ayant un passage débouchant dans lequel sont insérés deux adaptateurs isolant chacun étant doté d'une rondelle élastique dont le centre est percé d'un trou d'insertion. Une pièce de contact tubulaire est interposée entre les deux trous d'insertion, et un trou poinçonné interne de forme carrée se trouve sur au moins une des extrémités, dans des sections supérieure et inférieure de la pièce de contact. Une extrémité du trou carré n'est pas séparée du corps de la pièce de contact et forme deux parties opposées inclinées, ainsi que des parties arquées se prolongeant vers l'intérieur. Les pièces de contact sont formées dans un matériau en forme de plaque, qui est enroulé, et dont les deux bords ne se touchent pas, mais forment une fente étroite. Une fente étroite correspondante se trouve du côté opposé. Ces fentes permettent de connecter des composantes conductrices d'un câble coaxial, dont les dimensions peuvent couvrir une large gamme allant de 0,6mm à 1,3mm. Grâce à la fente étroite, la pièce de contact peut s'agrandir vers le haut et vers le bas lorsqu'un conducteur ayant un diamètre de 1,2mm à 1,3mm est inséré, ce qui permet de prévenir la fatigue du matériau et d'obtenir de l'espace libre.

IPC: A47C27/12
Filed: 1997-10-03
Abstract: This  is  a  furniture  upholstery  in  which  a  number  of compression spring elements 2 are made in the form of a cushion and joined to form a wide-stretched flat composite and in which, in every cushion-shaped compression spring element 2, web material 6 from threads is produced by meshing and folded 8 repeatedly to form the spatial element.   It is thereby  desirable  if  the  construction  of  the  furniture upholstery can be simplified with respect to additional layers and is improved with respect to softness and heat insulation. This is attained thereby that the thread of the web material is a loose textile thread twisted from partial threads and thereby that the partial strands are spun from fibers.  The furniture upholstery does not require softness-promoting and heat-insulating layers if the individual cushion-shaped or packet-like compression spring elements consist of a soft material and each have a number of distributed, very small empty hollow spaces, i.e. are heat insulating.

IPC: H03M7/40
Filed: 1998-01-06
Abstract: A multiple description coder pairs two samples and transforms the samples prior to quantizing and entropy encoding to improve coding efficiency while simultaneously achieving satisfactory performance with regard to distortion. For the N-Sample case, the multiple description coder pairs the samples using two different algorithms, and then performs the pairing transformation of the two variable case. One method assigns the lowest energy coefficients with the highest energy coefficients and so on until the middle coefficients are paired with each other.Another method assigns the highest energy coefficient with coefficients having energy below some predetermined value. Image coders and decoders are also included. A method for classifying the coefficients prior to performing the pairing transform is disclosed, which classifies the coefficients according to the amount and location of their energy.

Abstract: The present invention relates to a process for the manufacture of a plastics product from a polyolefin resin using a plasticiser monomer system which is substantially non-polymerisable under the product shape forming, conditions used in the product manufacturing process and which acts as a plasticiser or processing aid under said shape forming conditions, whilst being substantially polymerisable subsequently so as to produce a product substantially free of liquid plasticiser. The plasticiser monomer is mixed with the polyolefin resin; and the mixture formed into a desired product form. Polymerisation of the plasticiser monomer then provides a final product substantially free of liquid plasticiser.
