Abstract: La présente invention concerne un procédé de manipulation des couteaux de machines hache-bois, chaque couteau étant pourvu d'une lame. Le procédé de l'invention comporte les opérations suivantes: la lame (6) étant munie d'une lisse d'appui (8) d'une largeur fixe sur la partie arrière, le couteau (1) adopte une largeur qui restera en vigueur pendant sensiblement toute la durée d'utilisation de la lame de couteau. Pendant l'affûtage de la lame de couteau (6), l'ensemble du couteau (1) est déposé de la machine hache-bois, ce qui permet un examen visuel de la lame du couteau et une évaluation du niveau d'affûtage à réaliser. La lisse d'appui (8), une fois en place, est déposée, et une nouvelle lisse d'appui, dont la largeur correspond à la largeur de l'ancienne, augmentée du niveau d'affûtage, est fixée sur la partie arrière de la lame de couteau (6), à la suite de quoi, la lame de couteau subit un nouvel affûtage et le fil du tranchant subit un ébavurage. Après finition, le couteau (1) est soit directement remonté dans la machine hache-bois, soit rangé pour usage ultérieur dans un étui à couteau. L'invention concerne également un dispositif permettant la mise en oeuvre du procédé.

Title: Rock bit hardmetal overlay and process of manufacture
Inventor: DRAKE ERIC F
IPC: C23C30/00
Filed: 1998-09-17
Abstract: Methods of forming a new wear and abrasion overlay formed with the steel surfaces of components for earth boring bits, and the components formed by the methods are disclosed. The overlay comprises a hard material particulate containing a metal carbide and an alloy steel matrix. The volume fraction of the hard material particulate in the overlay is greater than about 75%, the average particle size of the hard material particulate is between about 40 mesh and about 80 mesh, and the thickness of the overlay is less than about 0.050 inches. The process of manufacture includes the steps of fixing a monolayer of hard material particulate to the surface of a flexible mold, filling the mold with materials and powders, and CIP densifying to form a preform. The preform is then forged to near 100% density in a rapid solid state densification powder metallurgy process. The resulting bit component has an integrally formed overlay with superior physical properties.

Title: Method and apparatus for measuring resistivity of an earth formation
Inventor: SEYDOUX JEAN P
IPC: G01N3/28
Filed: 1998-09-17
Abstract: The method and apparatus of the invention determines earth formation resistivity at extended depths into the formation by the use of telemetry transmission signals to measure the formation resistivity. The telemetry transmission signals carry measurement data from downhole sensors through the formation to an uphole receiver. The signal transmission is by means of induction telemetry. At the receiver, the signal is demodulated to obtain the transmitted measurement data. During the detection of the signal at the receiver, the signal amplitude is also extracted and is used to determine the formation resistivity. In addition, changes in the signal amplitude are also used to indicate formation boundaries for determining well location during directional drilling.

Patent CA-2249989-A1 (CA)
Inventor: CHAMBERS MARSHALL H JR
IPC: A63B53/14
Filed: 1997-04-25
Abstract: A golf club shaft (2) is described which has an upper grip portion (4) with significantly greater diameter than the largest diameter of the lower power portion (6), with the two portions joined by an S-shaped transition portion (8). The large diameter of the grip portion (4) permits recreational players or players with relatively weak hands to exert more power and greater control of the fine movements of the club shaft and golf club. The grip section (4) has a minimum diameter at least 35 ~  greater than the maximum diameter of the power section (6) and the transition section (8) has a length not greater than 15 % of the overall length of the shaft (2). The shaft may be made of any convenient material which can be formed into the curves of the transition section without imposing undue stresses in the curved portions. The shaft may be formed of metal or, preferably, a fiber/polymer composite material. The shaft permits the typical recreational player to improve his or her game by being able to obtain significantly better control of the alignment of club face and ball during the swing and shot, without requiring any increase in the player's normal hand and wrist gripping strength. It is also of utility for players who have arthritis or other debilitating conditions in their hands and wrists, in that it permits them to play better with their limited gripping ability, and in some cases permits resumption of limited play where to play at all had become unacceptably difficult because of the physical problems.

Abstract: The present invention relates to razor blade cutting edges which exhibit an improvement in the first shave. Conventional razor blade cutting edges exhibit surprisingly high initial cutting forces. Razor blades produced according to the present process exhibit significantly lower initial cutting forces which correlates with a more comfortable first shave. Improved blades according to the present invention involve treating conventional razor blade cutting edges having an adherent polyfluorocarbon coating with a solvent to partially remove some of the coating. Preferred solvents include perfluoroalkanes, petfluorocycloalkanes, perfluoropolyethers having a critical temperature or boiling point above the dissolution temperature for the polyfluorocarbon in the solvent. The present invention also relates to the method of producing these razor blade cutting edges.

Title: System for allowing i/o processor to operate under different transfer algorithms
Inventor: BLUMER MARC
IPC: G06F9/38
Filed: 1997-07-24
Abstract: A programmable DMA controller (110) that uses an instruction set dedicated to moving data efficiently over a bus (108), comprising a program memory (228), a program counter (226), a FIFO memory (222), a bus buffer (224), registers, an accumulator, and an ALU (220). The DMA controller instruction set comprises the following instructions: load, move, add, subtract, branch on zero, branch on not zero, lock, and interrupt. Another DMA controller embodiment uses a SIMD processor. In operation, a CPU downloads DMA programs to the DMA  controller. The DMA controller stores these programs in its program memory.  The CPU signals the DMA to begin a DMA transfer operation. The ALU and associated devices execute the program instructions to perform the desired DMA  transfer. The DMA controller then sends an interrupt to the CPU to indicate the DMA transfer is complete.
