Abstract: An endoscopic aspiration instrument (100) suitable for use with a trocar sheath in laparoscopic surgical procedures is disclosed for aspirating fluid from an ovarian cyst without leakage of the fluid into the peritoneal cavity. The endoscopic instrument (100) comprises an elongated suction tube member (103) having a needle guide (120) positioned within the passageway (121) thereof. The suction tube (103) and needle guide (120) are connected at the proximal ends (115,125) thereof with the use of a three access port connector (111). The first access port (114) connects to the proximal end (115) of the suction tube (103). The proximal end (125) of the needle guide tube (120) is extended through the first port (114) and connected to the second port (113) of the T-type connector (111). An aspiration needle (117) is inserted through a sealing cap (118) positioned over the second access port (113) and into the passageway (123) of the needle guide tube (120). A centering device (126) comprising a sleeve (127) and a plurality of radially extending arms (128) is positioned about the distal end (124) of the needle guide tube (120) for centering the needle guide tube (120) within the passageway (121) of the suction tube (103). The centering device (126) is also located a predetermined distance from the distal end (108) of the suction tube (103) for preventing the ovarian cyst from being drawn too far into the suction tube (103) to engage the ovarian cyst.

Abstract: The logging apparatus comprises a plurality of detecting devices (42, 43, 44) in alignment on a pad (20) which is urged against the wall of a borehole (11) for investigating earth formation (13). The detecting devices are responsive to a plurality of physical parameters of the formation, such as resistivity, density, photoelectric absorption coefficient, and propagation characteristics of microwaves in the formation, for example. The detecting devices are suitable for providing measurement signals representative of substantially equal investigated volumes having dimensions selected to be of the order of magnitude of one inch in the longitudinal, radial, and azimuthal directions of the borehole. Displacement of the pad (20) is detected, and in response to said displacement, depth corrected measurement signals are produced which relate to the same small volume zone of the formation situated on one side of the borehole. By combining these corrected signals it is possible to obtain a coherent interpretation of small volumes of the formation in the vicinity of the borehole.

Title: Method and apparatus for providing uniformly distributed filaments from a spun filament bundle and spunbonded fabric obtained therefrom.
Inventor: ZELDIN LEON M
IPC: D04H3/03
Filed: 1990-11-01
Abstract: A method and apparatus for providing uniformly distributed filaments from a spun filament bundle and a process for forming spunbonded fabric having superior uniformity and a favorable ratio between machine and cross direction tensile strengths. The apparatus includes a fiber transfer tube and a pair of adjustable deflector plates. The deflector plates form a channel having a tapering width for transporting the filaments in a stream of high velocity air. The apparatus may also include an electrostatic charging means for applying an electrostatic charge to each individual filament after it exits the channel. The method for providing uniformly distributed filaments includes a first stage of separating the filament bundle by the high velocity stream of air and may also include a second stage of electrostatically charging the filaments to achieve a uniform filament separation. The process for forming spunbonded fabric enables a fabric to be produced having a machine direction to cross direction tensile strength ratio less than about 1.5.

Abstract: Un dispositif de mesure de l'accélération au moyen d'un transducteur piézoélectrique comprend de manière connue un support (14, 16) avec un axe principal parallèle au sens de mesure de l'accélération, une masse sismique (20, 22) retenue de manière mobile par rapport au support et des éléments piézoélectriques (12, 12') qui coopèrent deux par deux et sont reliés à la masse sismique de manière à assurer leur excitation. Leur agencement permet de compenser des effets pyroélectriques. Le support comprend une traverse (16) transversale à l'axe principal. Les éléments piézoélectriques excités par compression sont incorporés à cette traverse, sur ses côtés opposés par rapport à la direction de l'axe principal, entre la traverse et la masse sismique (20, 22). On obtient ainsi, outre une insensibilité thermique, une grande insensibilité à la dilatation du sol et à des accélérations d'un type ou d'une direction autres que ceux des accélérations linéaires parallèles à l'axe principal.

Abstract: Une soupape atmosphérique s'utilisant dans un pétrolier est conçue avec des moyens (11, 12, 13, 33, 35, 36) d'application d'une force de fermeture supplémentaire s'exerçant sur le corps de la soupape si la chute de pression à l'intérieur de celle-ci s'élève sensiblement au-dessus d'une valeur prédéterminée. Cette augmentation extraordinaire de la chute de pression sera causée par une fuite due à une avarie se produisant sous la ligne de flottaison, par échouage et, de ce fait, la force de fermeture supplémentaire fermera très rapidement la soupape et contribuera à maintenir un niveau de vide élevé dans la soute, s'opposant à une fuite continue.

Abstract: PCT No. PCT/GB90/01044 Sec. 371 Date Jul. 24, 1991 Sec. 102(e) Date Jul. 24, 1991 PCT Filed Jul. 19, 1990 PCT Pub. No. WO91/17680 PCT Pub. Date Nov. 28, 1991.In the technical field of known cardholders for devices such as cards with magnetic stripes on which is encoded information and or data in the form of patterns of magnetism, the known cardholders offer no method of 'keeping' (in magnetism terminology) the magnetic patterns. The present invention is characterised by incorporating into the cardholders, keepers in the form of sheets of magnetically soft ferromagnetic material with high resistance. The benefit of the invention is obtained when devices are placed with the reading surface of their magnetized stripes in close contact with the surface of the ferromagnetic material which, making use of known properties of the material, then acts as keeper of the magnetic patterns.

     Surprisingly, it has been remarked that such membrane, which may normally not be used for carrying out filtration processes of foodstuffs, and particularly of wine, may yet find an application in these processes by means of a simple constructive step consisting in:
     the membrane having a rated void fraction (discriminating layer) of at least 0,1 µ and, advantageously, of 0,2 µ, and   the spacing mesh (15) disposed between the various windings having a thickness of at least 1 mm.

Abstract: A distributed control system including a control station that takes charge of control operation, and a remote input/output device that is connected to the control station through a remote input/output bus. In a normal state, cyclic scan transmission is carried out by using the remote input/output bus so that input/output data handled by the control station and input/output data on the remote input/output device side are maintained equivalently. The control station is provided with a continuation transmission service means that first performs transmission for urgent output only and then performs normal cyclic scan transmission service after the completion of the transmission for urgent output, an initialization start transmission service means that first performs cyclic scan transmission for input only, and an interruption duration measuring means that measures a period of transmission interruption duration of the remote input/output bus. When the result of measurement made by the interruption duration measuring means is shorter than a predetermined time, the continuation transmission service means is activated, whereas, when the result of measurement by the interruption duration measuring means is longer than the predetermined time, the initialization start transmission service means is activated. Thus, when the power supply recovers from a power failure, for example, the system can recover from the transmission interruption state rapidly and shift to the normal process control operation promptly.
