Title: Thermally bondable fabrics, preparation and use
Inventor: KRUPP STEPHEN P
IPC: D04H3/16
Filed: 1990-10-29
Granted: 2003-02-25
Abstract: Thermally bonded fabrics having high normalized tensile strength are disclosed. Blends of high molecular weight linear ethylene polymers and low molecular weight linear ethylene polymers provide improved staple fiber-forming capabilities over that found with either polymer taken alone. Staple fibers formed from the blends have Q values above 4.5 and/or I10/I2 values above 7. The staple fibers formed from the blends of high molecular weight linear ethylene polymers and low molecular weight linear ethylene polymers have a broader thermal bonding window than either linear ethylene polymer taken alone. At least one of the linear ethylene polymers useful for blending for forming staple fiber can be a higher alpha-olefin in the C3-C12 range, preferably in the C3-C8 range.

Title: Stackable drum
Inventor: PRZYTULLA DIETMAR
IPC: B65D21/032
Filed: 1990-12-21
Granted: 1998-07-28
Abstract: The invention concerns a large-capacity stackable drum with a substantially cylindrical sidewall and top and bottom ends. To improve the stackability, in particular the long-term stackability, an internal hydrostatic pressure which supports the side wall is initially produced when stacking several drums one on top of the other, in the gas space above the content and in the contents, of the drums stacked underneath, by virtue of the elastic flexibility of the top and/or the bottom of the drum, until a reduced stacking load acting through the top rim or grip ring of the drum into the drumwall is produced or support is provided through the bottom rim or grip ring.

Title: Direct coal liquefaction process
Inventor: RINDT JOHN R
IPC: C10G1/00
Filed: 1993-02-26
Granted: 1995-01-17
Abstract: An improved multistep liquefaction process for organic carbonaceous material which  produces a virtually completely solvent-soluble carbonaceous liquid product.  The solubilized product may be more amenable to further processing than liquid products produced by current methods.  In the initial processing step, the finely divided organic carbonaceous material is treated with a hydrocarbonaceous pasting solvent containing from 10% and 100% by weight process-derived phenolic species at a temperature within the range of 300°C to 400°C for typically from 2 minutes to 120 minutes in the presence of a carbon monoxide reductant and an optional hydrogen sulfide reaction promoter in an amount ranging from 0 to 10% by weight of the moisture- and ash-free organic carbonaceous material fed to the system.  As a result, hydrogen is generated via the water/gas shift reaction at a rate necessary to prevent condensation reactions.  In a second step, the reaction product of the first step is hydrogenated.

Patent CA-2095698-C (CA)
Title: Telescoping wall joint system, especially for seismic applications
Inventor: NICHOLAS JOHN D
IPC: E04B1/68
Filed: 1993-05-06
Granted: 1995-06-06
Abstract: A telescoping wall joint system is disclosed,  for connecting adjacent sections of an architectural structure, while accommodating substantial relative movement, such as might result from seismic activity.   Extended motion is provided in the joint system while avoiding the use of excessively wide components,  which are both costly and aesthetically undesirable.   A center cover plate, which spans the open space between two adjacent structural units, is received along one or both sides in a tubular sleeve. The cover plate is slidably extendable within a predeter-mined range in the tubular sleeves to accommodate normal movements of the structural units, such as may result from thermal  expansion  and  contraction,  for  example.    The tubular sleeves themselves are slidably received within fixed housings mounted on the respective structural units. When the separating movement of two adjacent structural units becomes so great that the cover plate reaches a limit condition in its slidable extension out of the tubular sleeves, the sleeves themselves slidably extend in relation to the housings in which they are carried.  The capacity of the  system  to  accommodate  separating movement  of  the structures is thus greatly increased.

Abstract: A sports ball comprises a hollow spherical-shaped inflatable tube; a covering layer comprising a thin rubber pouch and covering the tube; a reinforced layer which is adhered on the surface of the covering layer with a solution of an adhesive agent and an outer layer formed on the surface of the reinforced layer.  The covering layer is made of a material which does not permit the solution of the adhesive agent to pass therethrough and an inorganic lubricant is disposed between the tube and the covering layer, so that adhesion between the tube and the covering layer is prevented.  A method for making a sports ball includes the steps of: inserting an inflatable tube into a covering layer which comprises a thin rubber pouch and is made of a material which does not permit the solution of an adhesive agent to pass through the covering layer; injecting a powder of an inorganic lubricant into the covering layer; and inflating the inflatable tube into a spherical shape.  A reinforced layer is attached on the surface of the covering layer with the solution of an adhesive agent, alignment guides are formed on the surface of the reinforced layer by molding, and an outer layer is attached on the surface of the reinforced layer along those alignment guides. Alternatively, a method includes the steps of: spreading a powder or a suspension of an inorganic lubricant on an inflatable tube; inserting the tube into a covering layer which comprises a thin rubber pouch and is made of a material which does not permit the solution of an adhesive agent to pass through the covering layer; inflating the inflatable tube into a spherical shape and attaching a reinforced layer on the surface of the covering layer with the solution of an adhesive agent.  Alignment guides are formed on the surface of the reinforced layer by molding, and an outer layer is attached on the surface of the reinforced layer along those alignment guides.

Abstract: Un appareil ou module (10) de traitement de tranches à semi-conducteurs destiné à un groupe d'outils est équipé d'un suscepteur rotatif (40) de tranche unique qui amincit la couche limite gazeuse afin de faciliter le transfert de la matière vers la tranche (44) ou à partir de celle-ci dans, par exemple, le procédé CVD (Déposition en phase gazeuse par procédé chimique) pour couche de couverture ou dépôt sélectif de tungstène ou de nitrure de titane, et pour les processus de dégazage et de recuit. De préférence, une pomme d'arrosage (35) regardant vers le bas dirige un mélange gazeux à partir d'une chambre de mélange refroidie (30) sur une tranche (44) tournant à haute vitesse, par exemple, entre 500 et 1500 tours/minute, amincissant une couche limite pour l'écoulement du gaz radialement, vers l'extérieur, depuis un point de stagnation (198) au niveau du centre de la tranche. Les surfaces internes du réacteur nivelées comportent des chicanes (90, 101, 102) et des électrodes d'épuration du plasma (80, 90) afin de minimiser la turbulence. Des gaz inertes émanant de l'intérieur du suscepteur rotatif (40) minimisent la turbulence en remplissant les vides de la structure, empêchent la contamination de pièces mobiles, conduisent la chaleur entre le suscepteur et la tranche (44), et assujettissent par le vide la tranche au suscepteur (40). Le rebord (162) du suscepteur entoure la tranche (44) et peut être retiré pour le nettoyage, afin d'adapter des tranches de tailles différentes, et permet de modifier les matériaux du rebord par différents processus, tels qu'un processus qui résistera aux dépôts lors du procédé CVD, ou un processus qui balaye les gaz inutilisés dans le procédé CVD de couverture. Le rebord nivelle l'écoulement gazeux et réduit les gradients thermiques au niveau du bord de la tranche.
