Title: Retrievable bridge plug apparatus for sealing a pipe bore in a pipe string
Inventor: WINSLOW DONALD W
IPC: E21B33/12
Filed: 1991-06-03
Abstract: The   apparatus   comprises   a  packer  mandrel assembly having a  longitudinal mandrel bore  defined therethrough.   A packer  is  disposed on  the  packer mandrel  assembly,  for  sealing  between  the  packer mandrel assembly and the pipe bore in the pipe string upon engagement of the packer with an internal upset of the pipe string and subsequent application of upward force to the packer mandrel assembly.   A selectively positionable bypass is provided for preventing fill-up of a work string attached to the bridge plug apparatus as the work string and the bridge plug apparatus are run into position in the pipe string; communicating the pipe bore below the packer with a low pressure zone above  the packer through the mandrel bore prior  to sealing the packer against the pipe bore; isolating the pipe bore below the packer from the low pressure zone above the packer after sealing the packer against the pipe bore; and re-communicating the pipe bore below the packer with the  low pressure  zone above  the packer through the mandrel bore to balance pressure across the packer prior to unsetting said packer.

Title: Detection of malignant and premalignant conditions
Inventor: JONAS SONJA K
IPC: C12Q1/30
Filed: 1992-09-25
Abstract: A method of testing for a malignant or pre-malignant condition of the cervix by examination of a cervical cell sample, in which the test is performed on a fraction of the sample consisting predominantly of epithelial cells, which have been separated by a buoyant density method such as a discontinuous density gradient centrifugation. Following separation of the epithelial cells the cells are tested for an abnormal level of an enzyme associated with proliferating cells. Typically, the enzyme tested for is one selected from the group consisting of pentose phosphate shunt enzymes, ornithine decarboxylase, thymidine kinase, and ribonucleotide reductase, e.g. glucose-6-phosphate dehydrogenase and/or 6-phosphogluconate dehydrogenase.
Patent CA-2121132-A1 (CA)
Title: Automatic clutch control method and associated automatic transmission device
Inventor: ANTONOV ROUMEN
IPC: F16D43/09
Filed: 1992-10-14
Abstract: The epicyclic gear train consists of a driving shaft and pinion (1,3), satellite pinions (4), unidirectional crown wheel (7) and clutch (14,15). The clutch operates between the crown wheel and a satellite bearer wheel (5) attached to the output shaft (6). At high speeds increasing centrifugal force acting on plates (31) opens the clutch, lowering the gear ratio which is restored to direct drive at lower speeds. Heavy accelerator pressure operates an electromagnet (123,124) which delays clutch opening as does high input torque through an axial force (FAC) at the helicoidal gears (7). <IMAGE>

Abstract: A network system includes a wavelength-multiplexing transmission path for multiplexing and transmitting a plurality of wavelengths, and a plurality of terminal equipments connected to the transmission path.  A transmission wavelength and a reception wavelength are assigned in advance to each of the plurality of terminal equipments.  When data must be transmitted between the terminal equipments, and when a transmission wavelength of a transmission source terminal equipment as a transmission source of the data is different from a reception wavelength of a destination terminal equipment as a destination of the data, wavelength conversion is performed such that a terminal equipment located between the transmission source terminal equipment and the destination terminal equipment temporarily receives the data, and transmits the data at another wavelength.

Abstract: A system for playing card games remotely includes both a multimedia communication system that allows players located remotely from each other to seeand hear each other, and a "card toaster" and associated image recognition system at each game site which receives and manages a physical deck of cards at every site at which the game is being played. The toaster has the capability of (1) reading cards, for example, by scanning them, (2) finding particular cards, and, if necessary, sorting them, and (3) distributing cards, such as by dealing them. The system enables the players to deal and then play a game, such as the game of bridge, in a manner which closely approximates the manner in which a game is played when all players are co-located. Thus, once play is started, the image recognition system reads the cards played on a table at any site, and transmits information regarding those cards to the other sites. At the other sites, the card toaster is signaled and arranged to distribute the same cards, face up on the table. (Fig. 1)

Title: Web cleaner apparatus and method
Inventor: POLLOCK RODNEY E
IPC: B08B5/02
Filed: 1994-09-29
Abstract: ABSTRACT OF THE DISCLOSURE     An apparatus and method for cleaning a moving web of sheet material. The apparatus includes a Coanda nozzle having an elongated, curved foil and a slit for directing gas at a high rate of speed along the foil.   The gas from  the foil impacts a layer of air entrained by the web of sheet material flowing in an opposed direction.  Impact occurs within a gap formed between  the foil and the web which becomes increasingly restricted in the direction of movement of the web.  The entrained layer of air is caused to reverse direction within the gap and is mixed with the gas from the nozzle under turbulent conditions to clean the web and remove particulate material such as dust therefrom.

Abstract: Abstract 1.   Live vaccine having an increased stability 2.1  The safety of bacterial live vaccines is guaranteed by deletions, the stability of which with respect to in vivo repair lying in the range of about 10-12. The high requirements of the World Health Organisation and the wide-spread opinion about the alleged instability in the use of live vaccines under practical conditions let it appear to be necessary to enhance the already existing safety buffer by yet another increase of at least the factor 10-7.   2.2  The stability of a live vaccine produced from at least one metabolic drift attenuated, immunogenic, stable single or multiple marker live vaccine with or without envelope mutation and an optimal attenuation level adapted to the sensitivity of the host species is increased by using as vaccine strain its revertant, as a suppressor mutant still having the attenuation or/and envelope markers.   2.3  Different variants of the live vaccine as well as of a special live vaccine for chickens and chicks and of their production are provided.
