Patent CA-2219247-C (CA)
Title: Injection molding apparatus having a melt bore through the front end of the pin
Inventor: BABIN DENIS L
IPC: B29K23/00
Filed: 1997-10-23
Granted: 2006-12-05
Abstract: Multi-cavity injection molding apparatus for three layer molding having elongated pins for fixed pin gating or valve gating. Each elongated pin has a central melt bore extending rearwardly from its front end to a number of laterally extending bores. A low viscosity barrier material such as EVOH or nylon flows through these bores to the gate leading to the cavity. This allows coinjection with fixed pins and sprue gating in one embodiment and by valve gating in another embodiment.

Title: Removal of material by polarized radiation and back side application of radiation
Inventor: JOHNSON ANDREW W
IPC: B08B7/00
Filed: 1996-06-05
Granted: 2007-05-08
Abstract: An apparatus and method for selectively removing undesired material from the surface of a substrate provides a flow of inert gas over the undesired material substrate surface while irradiating the undesired material with energetic photons. The invention enables removal of undesired material without altering the physical properties of the material underlying or adjacent the removed, undesired material. Removal effectiveness may be enhanced by utilizing polarized energetic photons.  Directing a laser beam to the back side of a transparent substrate may enhance the effectiveness of removal.

Abstract: A silicon-based sleeve type chemical reaction chamber (41) that combines heaters, such as doped polysilicon for heating, and bulk silicon for convection cooling. The reaction chamber combines a critical ratio of silicon and silicon nitride to the volume of material to be heated (e.g., a liquid) in order to provide uniform heating, yet low power requirements. The reaction chamber will also allow the introduction of a secondary tube (45) (e.g., plastic) into the reaction sleeve that contains the reaction mixture thereby alleviating any potential materials incompatibility issues. The reaction chamber may be utilized in any chemical reaction system for synthesis or processing of organic, inorganic, or biochemical reactions, such as the polymerase chain reaction (PCR) and/or other DNA reactions, such as the ligase chain reaction, which are examples of a synthetic, thermal-cycling-based reaction. The reaction chamber may be used in synthesis instruments, particularly those for DNA amplification and synthesis.

Abstract: A dual injection system for selectively injecting a treating fluid in a predetermined treating zone (16) of a well bore hole (10) adjacent a productive zone (14) with a marker fluid injected from the annulus (36) outside a coiled tubing string (34). The coiled tubing string (34) is inserted within the well bore hole (10) and a sensor (40) is provided on the coiled tubing string (34) with a lower end portion (42) extending below the sensor (40) for the discharge of the treating fluid from the lower end (44) of the extending end portion (42). The sensor (40) senses a detectable material, such as a radioactive material in the marker fluid injected from the annulus (36) outside the coiled tubing string (34) and may be reciprocated within the well with the coiled tubing string (34) for determining the interface (46) between the marker fluid and the treating fluid so that the treating fluid does not enter the productive zone (18). In one embodiment (Figure 4) the productive zone (14A) is located below the treating zone (16A) and the treating fluid contains the marker to provide the marker fluid.

Abstract: Apparatus and method for monitoring a system in which a fluid flows and which is characterized by a change in the system with time in space. A preselected place in the system is monitored (14) to collect data at two or more time points (12) correlated to a system event. The data is indicative of a system parameter that varies with time as a function of at least two variables related to system wash-in and wash-out behaviour (15). A calibration map is made (20) on a calculated basis with each pixel or voxel representative of a color hue indicative of wash-out behaviour (19) and a color intensity indicative of wash-in behaviour (16). When a satisfactory map is obtained, the collected data is processed on the basis of the map to obtain an image of the preselected place with each spatial unit thereof correlated with a color hue and a color intensity. Software and a data processing system are provided to develop the calibration map. The calibration map and image of the preselected place are also novel implementations.

Granted: 2004-02-10
Abstract: An improved annular flow monitoring apparatus is described which improves fl ow monitoring accuracy by taking account of scale thickness when calculating flowrate measurement. This is achieved, in one aspect of the invention, by providing a flow restrictor insert (14) into the bore of a conduit or pipe (12) with the flow restrictor insert being arranged so as to create an annular flowpath around the insert, the flow restrictor insert having at least two substantially co-axia l portions (36, 40) of different diameters with sufficient pressure monitoring stations (P1, P2, P3) being provided so as to allow the calculati on of at least two pressure differentials. This can be implemented by providing three absolute pressure gauges which may be located at three appropriate locations (P1, P2, P3) in the bore of a carrier or by using two differential sensors connected to the monitoring stations to calculate pressure differentials from the three bores. The three pressure monitoring bores and two differential pressure sensors (43, 45) may be located within the flow restrictor insert (14), and the pressure sensors being located in respective co-axial portions. In another embodiment a multiple venturi flowmeter (5) is used to calculate scale deposition with the same type and number of measurements. Using standard flu id mechanics analysis, a mathematical model is derived which computes gross flowrate from the three pressure measurements (non- differential) in a scaling environment. For each embodiment, a value of scale thickness is a byproduct of the calculation and this is used as the basis for a downhole scale indicator.

Abstract: This invention relates to methods and apparatus for making and using node cuffs (14) on transcutaneous or intra-body prosthetic devices (20) such as catheters, to effect improved stability of the prosthesis/tissue opening site interface. In particular, the node cuff apparatus of the present invention provides for positioning of the tissue opening site in a manner which facilitates more rapid establishment of a stably bio-integrated and well healed prosthesis/tissue opening site interface. In addition, in accord with the methods of the present invention, non bio-integrated portions of the node cuff can be simply and easily removed from the underlying prosthetic device to facilitate maintenance of the stably bio-integrated interface. Preferably, this removal takes place after a period of time during which the interface has become stably established. In accord with the methods and apparatus of t he present invention, thus infections or healing difficulties at the prosthesis/tissue opening site interface are greatly reduced, and a more comfortable and stable interface is more rapidly established and more easily maintained.

Abstract: A radio communications device has a memory having stored therein a user application program (16), a telephony program (18) and an application programming interface (API) 30 between these. Various aspects of the API (30) are described. In one aspect, the API (30) has a command for establishing a call and the telephony program (18) accepts, as an argument of the command for establishing the call, an array identifying several terminal objects (54-58), thereby permitting establishment of a call for multiple terminal objects. In another aspect, groupings of events are described and an API (30) command defines an event class from one of the groups together with an ID defining an event within the event class. In a further aspect, a program in the telephony program (18) is called to create a call object (50). The call object (50) is created regardless of whether radio service for the radio communications device has been established.
