Patent CA-2261321-A1 (CA)
Inventor: BARFUSS JACK E
IPC: F01C1/10
Filed: 1999-02-11
Abstract: This invention pertains to the fully rotary, internal combustion engine capable of building up the compression in the sealed compartments. This design, which has all advantegeous attributes of a conventional gas turbine like fully rotary motion, continuity of Otto cycle, independency of working surfaces adds the best feature of the classic reciprocating engine -compression in sealed compartments. In this way, this engine-turbine called the Sealed Compression Turbine Engine or simply the SCOT Engine is expected to be much more efficient than any reciprocating or partially reciprocating engine and, unlike the classic gas turbine, be fully controllable in the range from as fast as the maximum speed of the gas turbine down to the idling speed of the piston engine. A wide scope of both terrestrial as well as marine applications is open to SCOT  as a result of its speed adjustability.

Inventor: AMSE ROBERT
IPC: B65B27/08
Filed: 1999-03-02
Abstract: Two per se known cross-strapping devices (10, 11) to which packages or bundles (1, 2 ... 5) to be strapped are supplied in a conveying direction (F) in which one package or bundle at a time is positioned and crosswise strapped and out of which strapped packages or bundles are conveyed in the same conveying direction (F)) are arranged in direct succession and are operated as a "tandem" by supplying two packages or bundles (1, 2), one to each one of the devices, by simultaneously strapping them and by conveying them array again simultaneously. For this purpose, a mutual control mode is necessary in which mutual control mode, in the two devices conveying steps (b) are carried out alternating with strapping steps (a) whereby the conveying stroke (2h) of the conveying steps is twice as long as when operating one only device.      Compared to a single cross-strapping device, the arrangement has an increased performance and requires a minimal amount of additional space.   Furthermore, it offers a limited performance also for the case of one of the devices not being operative in which case the other device is operated as a single device without substantial additional effort. The arrangement is suitable also for other processing devices which can be operated in alternating processing and conveying steps.

Title: A tonometer system for measuring intraocular pressure by applanation and/or indentation
Inventor: ABREU MARCIO MARC AURELIO MART
IPC: A61B5/00
Filed: 1997-09-04
Abstract: A tonometer system for measuring intraocular pressure by accurately providing a predetermined amount of applanation of the cornea, and detecting the amount of force required to achieve the predetermined amount of applanation. The system is also capable of measuring intraocular pressure by identing the cornea using a predetermined force applied using an indenting element, and detecting the distance the indenting element (16) moves into the cornea when the predetermined force is applied, the distance being inversely proportional to intraocular pressure. Also provided is a method of using a tonometer system to measure hydrodynamic characteristics of the eye, especially outflow facility.    The tonometer system includes a contact device for placement in contact with the cornea and an actuation apparatus (6) for actuating the contact device so that a portion thereof projects inwardly against the cornea to provide a predetermined amount of applanation. The system further includes a detecting arrangement (8) for detecting when the predetermined amount of applanation has been achieved, and a calculation unit responsive to the detecting arrangement (8) for determining intraocular pressure based on the amount of force the contact device must apply against the cornea in order to achieve the predetermined amount of applanation. An indentation distance detection arrangement is also provided for use when intraocular pressure is to be deteced by indentation. In carrying out the method, the system is used to detect intraocular pressure between successive steps of forcing intraocular fluid out from the eye.

Title: Viscosity control for molten plastics prior to molding
Inventor: IBAR JEAN-PIERRE
IPC: B29C48/14
Filed: 1997-12-12
Abstract: Controlling viscosity of molten polymers, such as polycarbonate, prior to a molding operation such as injection molding, extrusion, thermoforming or blow molding, involves a reduction of viscosity in the plastic melt at constant temperature, by the action of a vigorous mechanical extensional shear vibration, with minimum or no external pressure, at a constant amplitude and frequency, causing the melt to become highly elastic and simultaneously fatigued for a certain time at that temperature, maintaining this high elastic state until the macromolecules have partially or totally disentangled, in a controllable manner, at which stage the melt is ready for a molding operation such as a simple quenching operation or an extrusion process followed by quenching to produce pellets or compounds with a better mix or a lower viscosity when remelted, or an injection molding operation where the melt viscosity has been greatly reduced allowing a better processability of the injected part.

Title: Z-chromosomal markers derived from chicken (gallus domesticus) and use thereof in chromosomal mapping
Inventor: SMYTH J ROBERT JR
IPC: C12Q1/6876
Filed: 1998-01-02
Abstract: We have developed a chicken (Gallus domesticus) Z-chromosome-specific DNA library in a phage vector, by means of chromosome microisolation and microcloning. The chromosomal origin, specificity and purity was evaluated by fluorescent in situ hybridization (FISH) on chicken metaphases. Heterologous chromosome painting, using this Z-chromosome-specific probe on turkey (Meleagris gallopavo) metaphases identified its homologous Z-chromosome, under the same stringent conditions as that used in the chicken, indicating a high degree of Z-chromosome sequence homology among these two species. This chicken Z-chromosome library will facilitate the development of Z-chromosome-specific DNA markers that will be useful for genetic mapping in the domestic chicken and related avian species. The Z-chromosome-specific DNA probe will also be useful for studies pertaining to the sex chromosome evolution in avian species.
