Title: Method of flash-butt contact welding of a pair of workpieces
Inventor: KUCHUK-YATSENKO SERGEI I
IPC: B23K11/04
Filed: 1989-12-28
Abstract: METHOD OF FLASH-BUTT CONTACT WELDING OF A             PAIR OF WORKPIECES Abstract of the Disclosure A method of flash-butt contact welding of a pair of workpieces including flashing and upsetting of the workpieces to be welded. In the process of flashing the workpieces are stopped as soon as the actual value of the welding current attains a preset value of the stopping current; the stopped workpieces are put into vibratory motion. As the actual value of the welding current of the vibrating workpieces drops down, the workpieces resume their translation towards each other and stop vibrating.
Patent CA-2007626-A1 (CA)
Inventor: RUDY MARION FRANKLIN
IPC: F16F1/36
Filed: 1990-01-11
Abstract: A product in the form of a cushioning device made from thermoplastic film containing crystalline material inflated to a relatively high pressure and sealed at the time of manufacture. The product maintains the internal inflatant pressure for long periods of time by employing a form of the diffusion pumping phenomenon of self-inflation in which the mobile gas is the gas components of air other than nitrogen.          Improved and novel cushioning devices use new materials, for the film of the enclosure envelope which can selectively control the rate of diffusion pumping, thereby permitting a wider latitude flexibility and greater accuracy in the design of such new cushioning device, thus improving the performance and reducing cost of such devices while eliminating some of the disadvantages of the earlier products. It is possible to permanently inflate certain types of new devices using readily available gases such as nitrogen, or air in which case nitrogen forms the captive gas.

Title: Process for the comminution of materials
Inventor: KAPPEL JOHANNES
IPC: D21B1/06
Filed: 1990-08-07
Abstract: The invention relates to a process for treating high consistency fibrous materials. The fibrous material, a reaction agent and a carrier gas are contacted in a comminuting zone under a closed system, to separate the fibrous material into smaller segments and react the material with the reaction agent. The segmented fibrous material, reaction agent and carrier gas are passed to a reaction zone for further reaction between the segmented fibrous material and the reaction agent. The process includes separating the reaction agent in a liquid phase from the carrier gas to produce a remaining gaseous fraction including vapors of the reaction agent, separating the gaseous fraction of the reaction agent and the carrier gas from the reaction zone, and recycling the gaseous fraction to the comminuting zone for further reaction. The reacted, segmented fibrous material then is discharged from the reaction zone.

Title: Methode et dispositif pour stimuler une zone souterraine par injection differee de fluide provenant d'une zone voisine, le long de fractures faites depuis un drain fore dans une couche intermediaire peu permeable
Inventor: GADELLE CLAUDE
IPC: E21B43/26
Filed: 1990-12-28
Abstract: : La zone souterraine et la zone voisine sont par exemple l'une un gisement pétrolifère et l'autre une nappe aquifère sous-jacente à une pression supérieure à celle régnant dans cette zone. La méthode consiste essentiellement à percer au moins un drain dévié (horizontal ou presque, de préférence) dans la couche intermédiaire qui est par exemple une zone rendue peu perméable en raison de la présence de produits hydrocarbonés lourds et visqueux et à relier les deux zones par des fractures de la couche intermédiaire faites depuis le drain. Le drain peut être équipé d'une conduite percée d'orifices sur une partie de sa longueur, de blocs d'obturation permettant le confinement total ou partiel du drain et de moyens de pression pour provoquer des fractures dans la couche intermédiaire au niveau de ces portions confinées. Par des fractures faites en cours de production, on peut injecter de l'eau sous pression de la zone dans la zone pétrolifère et mieux drainer la formation. Application à l'exploitation des gisements pétroliers par exemple.

IPC: B30B11/02
Filed: 1991-03-20
Abstract: ABSTRACT OF THE DISCLOSURE      A  method  of forming a cylindrical  compact  for  a cylindrical magnet is improved by moving a core pin and a die  of  a  mold  at the same  time  of   pressing  maget materials with a pressing punch in the same direction  as that  of the pressing punch at travelling speed Vc and Vd indicated by following equations :              Vc=m?Vp(0.5 ? m ? 1.0) Vd=n?Vp(0.5 ? n ? 1.0) where Vc is the travelling speed of the core pin,  Vd  is the  travelling  speed of the die and Vp is the  pressing speed of the pressing punch. According to this invention, it  is  possible to form the thin-walled  and  long-sized cylindrical  compact  by  utilizing the frictional  force caused  between  the  mold and the magnet  materials  for forming the compact very effectively in order to obtain a thim-walled   and  long-shaped  cylindrical   magnet   as compared with the conventional one.

Title: Stabilizing cylinder for a rough terrain forklift

Abstract: STABILIZING CYLINDER FOR A                ROUGH TERRAIN FORKLIFT     Abstract of the Disclosure A stabilizing device for use with a vehicle such as a rough terrain forklift.  The stabilizing device employs a cylinder with a movable piston mounted therein, with upper and lower piston rods extending from the piston,  The cylinder is fixed to the frame of the vehicle, and an end of the lower piston rod is fixed to the rear axle of the vehicle, which is pivotably mounted to the underside of the frame.  A fluid communication system including restrictive orifices provides communication between upper and lower chambers of the cylinder so that, during upward or downward movement of the piston within the cylinder, fluid is forced to pass through the restrictive orifices to provide damping of oscillations, and thereby a firmer feel and more stable handling to the vehicle.  A valve is movable to varying positions in response to the position of the boom relative to the frame, so that a more restrictive orifice is employed when the boom is moved above a predetermined angle, to increase the stability of the vehicle.  When a larger predetermined angle is attained, the valve is moved to a lock-out position to prevent fluid communication between the cylinder chambers, providing a four-point stability stance to the vehicle.  Alternatively, the valve can be moved to its lock-out position by operation of a manual toggle switch by the operator.

Title: Moisture-impermeable stranded electric conductor
Inventor: DOWNIE IAN
IPC: H01B13/32
Filed: 1991-05-24
Abstract: ABSTRACT      In the manufacture of a cable core comprising a moisture-impermeable multi-wire conductor, the conductor is stranded in a conventional manner and, after a fluid-impermeable layer of plastics material has been extruded over the conductor to form the core, the core is wound around the hub of a cable drum in such a way that each end of the wound core is exposed and accessible.  One exposed end of the wound core is sealed and air is evacuated from the conductor interstices by a vacuum pump cemented to the other exposed end of the wound core.  A source of semi-conductive moisture-impermeable compound in a liquid or semi-liquid state is then connected to the exposed end of the wound core and moisture-impermeable compound is drawn into and flows along the evacuated conductor interstices until the interstices are filled throughout the length of the core.  The moisture-impermeable compound in the interstices is then permitted to solidify or thicken to such an extent that it will not readily flow from the conductor.

Filed: 1991-03-12
Abstract: A method of and apparatus for testing the chamber of a test part (P) for leaks in which the chamber is filled with gas under pressure and the differential pressure drop over a predetermined interval of time is determined. The temperature of the part being tested is determined, and a storage table (60) of correction values corresponding to the estimated differential pressure drop attributable to the temperature of the part is provided. The correction value for the temperature of the part is selected by a correction value selector (84) from the storage table and substracted from the measured differential pressure drop by a calculator (80) to obtain a corrected differential pressure drop. If the corrected differential pressure drop is within a range below a predetermined amount, a fraction of it is summed back to the storage table to adjust the selected correction value.
