Abstract: A drag-type drill bit for boring an earth formation having a plurality of cutting elements (20) formed thereon. Each cutting element includes a cutting surface (30) having a cutting edge (34) formed thereon. During boring, the cutting edge is embedded into an earth formation (36) so that the formation is received against a portion of the cutting surface. As the cutting surface advances against the formation, a chip forms. The chip has a first surface (62) directed generally toward the cutting surface and a second surface (64) directed generally in the direction of cutting element travel. A number of different embodiments are disclosed which include means formed on and in the cutting surface for communicating drilling fluid pressure via slots or discontinuities (42) to a location on the cutting surface relatively close to the cutting edge. Drilling fluid pressure across the chip is thus equalized thereby preventing the chip from being urged against the cutting surface due to the difference between the formation pressure and the drilling fluid pressure.

Abstract: An AC-powerable portable computer has an interior sheet metal chassis portion (30) within which computer operating components are operatively disposed. The chassis has a removable metal access wall portion (40) and is positioned within a plastic outer housing (12) of the computer having a removable access wall (18) that outwardly overlies the sheet metal access wall portion. A key-operable security locking system (80) incorporated in the computer has a pawl portion (88) positioned within the sheet metal chassis. The pawl is selectively movable to a locking position in which it interlocks with each of the plastic and sheet metal access walls and precludes their normal removal from the computer. When the plastic and sheet metal access walls are locked to the computer in this manner, entry into the chassis interior requires that the plastic access wall be broken, and that the metal access wall be forcibly bent away from the balance of the chassis structure. Accordingly, the access walls cannot be reinstalled on the computer without leaving readily visible evidence of the forcible entry into the computer. The locking system thus provides a dual barrier to unauthorized physical entry into the chassis, and visually alerts the legitimate user of the computer that a break-in has been attempted or achieved.

Abstract: To ensure that only liquid helium is delivered to a cryostat during liquid helium refill, the arrangement automatically diverts hot gas which is produced during cooling of the transfer tube, away from the cryostat. The arrangement comprises a three way valve (4) which is operated by pressure variations as a result of cooling part of an enclosed volume of helium gas (7,15) to a temperature near the normal boiling point of the liquid at atmospheric pressure. The arrangement provides the advantage in that the transfer of helium to a cryostat now becomes very much a less skilled operation.

Abstract: A liquid-vapour contact column includes an array of vertically spaced horizontal liquid-vapour contact trays having generally circumferential sides and arrangement of downcomers to conduct liquid from each tray in the array to the tray below. Each tray has gas passages to enable gas to pass into contact with the liquid. A weir 46 is disposed on the floor of at least one downcomer. Each side of the weir 46 is spaced from the corresponding side of the downcomer. This arrangement counteracts a tendency for liquid flowing along the floor of the downcomer to become detached from the sides of the downcomer, such detachment leading to maldistribution of liquid on the tray and hence to less efficient operation of the column.

Abstract: L'invention concerne les tubes intensificateurs d'image, et plus particulièrement les intensificateurs d'image radiologique. Pour obtenir une répartition plus uniforme de brillance de l'image de sortie pour une illumination uniforme d'entrée, l'invention propose d'intercaler entre la couche scintillatrice (12) et la photocathode (16) une couche intercalaire (14) d'épaisseur radialement variable (en pratique plus épaisse au centre) réalisée en un matériau qui modifie les propriétés émissives de la photocathode en fonction de son épaisseur. En pratique la couche intercalaire peut être tout simplement l'électrode d'In2O3 déposée sous la photocathode, l'épaisseur de cette couche étant variable radialement pour obtenir la compensation de profil de brillance désirée. <IMAGE>

Abstract: The method relates to active antennas having electronic scanning and consisting of an array of radiating elements (Eo,...Em) excited on emission by individual power amplifiers (Ao,...Am) arranged in active modules (M'o,...M'm) placed as close as possible to the radiating elements (Eo,...Em). It consists in reducing the level of the harmonics emitted by dividing the power amplifiers (Ao,...Am) into at least two groups and by impressing upon the power amplifiers (Ao,...Am) a non-zero common value of phase shift  phi  which is added to the individual values of phase shift which are required by the electronic scanning and which is obtained, for one of the groups, at the input of the power amplifiers and for the other group at the output of the power amplifiers. The common value of phase shift  phi is advantageously taken equal to  pi  in order to reduce the even harmonics or  pi /2 in order to reduce the odd harmonics. The reduction in the level of the harmonics is due to the fact that the latter no longer add together in phase in the signal from the active antenna but with a phase difference equal to (n-1)  phi , n being the order of the relevant harmonic. <IMAGE>

Abstract: Un circuit de minimalisation de distorsion, avec alimentation vers l'avant reçoit un signal d'entrée (200) et l'achemine le long de deux parcours de signaux. L'un des parcours, celui du signal principal, comprend un générateur de distorsion, tel qu'un amplificateur de puissance (202), qui produit un signal de sortie comprenant un élément de distorsion. L'autre parcours, celui du signal à alimentation vers l'avant, comprend une ligne de retard (215), (207) sensible au signal d'entrée et servant à injecter le signal d'entrée (200) vers l'avant, sans distorsion. Le signal de sortie provenant du générateur de distorsion est combiné avec un signal d'entrée injecté en aval pour produire un signal d'erreur représentant l'élément de distorsion. Un circuit de réaction est utilisé pour détecter un courant continu proportionnel à la puissance du signal d'entrée et pour régler l'amplitude et la phase des signaux dans les parcours du signal à correction en aval ou du signal principal afin de réduire le rapport porteur/distorsion du signal d'erreur. Après ceci, le signal d'erreur est soustrait du parcours de signal principal pour annuler tout élément de distorsion qui s'y trouve.
