Patent CA-2177490-A1 (CA)
Inventor: STERMAN WESLEY D
IPC: A61B17/56
Filed: 1994-11-18
Abstract: The invention provides devices and methods for performing less invasive surgical procedures with an organ or vessel. One embodiment provides a method of closed chest surgical intervention within an internal cavity of a patient's heart. The patient's heart is arrested and cardiopulmonary by-pass is established. A scope (25) extending through a percutaneous intercostal penetration in the patient's chest is used to view an internal portion of the patient's chest.  The penetration is formed in a wall of the heart using a cutter (110) introduced through the percutaneous penetration.  An interventional tool is then introduced through a cannula (22) positioned in the penetration.  The interventional tool is inserted through the penetration to perform a surgical procedure within the internal cavity under visualization by a scope (25). A cutting tool is introduced into the patient's left atrium from a right portion of the patient's chest to remove the patient's mitral valve. A replacement valve (36) is then introduced through the intercostal space and through the penetration in the heart and the replacement valve is attached in the mitral valve position.

Abstract: A self-contained composite roofing batten bar has a layer of adhesive material secured to the bottom or undersurface portion of a roofing batten bar or strip. The adhesive material is tacky or sticky at room temperature and preferably comprises a butyl rubber composition. In view of the inherent tackiness or stickiness of the butyl rubber adhesive composition, one surface of the adhesive material layer is inherently adhered to the bottom or undersurface portion of the roofing batten bar or strip and the other lower or undersurface portion of the adhesive layer is covered by a releasable paper backing strip. When it is desired to use the composite batten bar in order to secure, for example, a roofing membrane to underlying roofing structure, the releasably paper backing strip is simply removed thereby exposing the lower or undersurface portion of the adhesive layer. The batten bar or strip is then able to be mounted upon or atop the roofing membrane at predetermined locations as dictated by the overall roofing installation requirements. The batten bar or strip may be provided with preformed apertures or holes for the reception of suitable fasteners such that the batten bar and roofing membrane assembly may be fixedly secured to the underlying roofing structure or decking.

Patent CA-2189440-A1 (CA)
Inventor: O'HALLORAN MICHAEL L
IPC: A01D34/80
Filed: 1994-05-20
Abstract: A crop harvester (10) is provided with a rotary type cutter bed (30) in which a series of rotary cutters (32a-32j) extend across the path of travel of the machine for rotation about individual upright axes. A hydraulic drive for the cutter bed includes a variable volume pump (210) driven by the output shaft of an engine (208) associated with the harvester. The operating circuit of the hydraulic drive pumps oil through the circuit at a certain rate of flow, depending upon the engine speed and the position of a swash plate (260) within the pump. A control circuit communicating with the operating circuit (228) is capable of sensing load in the operating circuit tending to lug down and reduce the speed of the engine (208), which would normally reduce the flow rate and hence the cutter speed. However, in response to detecting such increased load, the control circuit compensates by adjusting the position of the swash plate (260) so as to correspondingly pump more oil at the lower engine speed, thus maintaining the cutter speed essentially constant.

Title: Door, light, and method
Inventor: HERBST WALTER B
IPC: E06B5/00
Filed: 1997-04-03
Abstract: Disclosed is a primary door with window lights in the extreme upper portion. Optionally, the door can use a lowering window or a lowering screen self stored interiorly in a frame defined by the window track and the screen track and a lower stop in the upper half of the door. Thus the door can have a window, or a screen, or indeed can be left wide open for ventilation without diminishing the privacy afforded by the door since entire screen/window assembly is a plane well within the upper half of the door. In addition, replaceable decorative covers, such as muttons, are optionally on the outside and the inside of the door over the window area. The method relates to forming a door frame with a window opening defined by a frame and a cavity in the upper half of the door which contains the elements of vertical tracks for engaging the window and screen in a perpendicular horizontal stop for defining a frame for the window/screen assembly well within the upper half of the door. Optionally the door is formed as an inner and outer half, two halves being press-fittingly or otherwise secured to each other. Thereafter, the window and screen are inserted, and then decorative muttons or other coverings optionally applied.

Title: Method of making a diamond-coated composite body
Inventor: OLSON JAMES M
IPC: B23P15/28
Filed: 1997-04-07
Abstract: At least the surface region of a cutting tool substrate made of tungsten carbide in a cobalt matrix is carburized to chemically passivate the cobalt prior to deposition of diamond film on it. The passivation improves adhesion by preventing reaction of the cobalt with the diamond in the course of the deposition process. To further improve adhesion of the diamond, cobalt is removed from the exposed surfaces of the tungsten carbide grains by heat treatment in inert gas or by hydrogen plasma.
Patent CA-2202769-A1 (CA)
Title: Wide band radio-frequency converter having multiple use of intermediate frequency translators
Inventor: SCHMIDT KENNETH M
IPC: H03J5/24
Filed: 1995-10-12
Abstract: A wideband RF-to-IF frequency converter providing multiple use of frequency conversion components for many different types of RF input signals. In specific examples, many different types of signals for communication, navigation, and for interrogation are processed through at least partly common frequency-conversion channels. Such RF input signals in the range from approximately 2 MHz to 2,000 MHz are converted to output IF frequencies, such as 1 MHz and 30 MHz, for further processing in the common receiver. Some narrow band signals, after conversion to IF, are subjected to off-center filtering in relatively broadband IF filters. Input RF filters are not used.  Among several frequency conversion stages, only one of the local oscillator signals is tunable; but it is made tunable in relatively small, precise steps by using a double phase-locked loop arrangement in the frequency synthesizer.

Title: Centralized call control in a data access transport service
Inventor: MYERS ROBERT
IPC: H04L69/40
Filed: 1997-05-30
Abstract: In a Data Access Transport Service (DATS) wherein Data Service Providers (DSPs) share dial-in access (e.g. analog modem or Integrated Services Digital Network (ISDN) access)  resources from a common pool maintained by a Local Exchange Carrier (LEC)  (or potentially a DSP), each DATS subscribed DSP's virtual resources must have high availability.  A system is disclosed wherein an Internet Protocol Data Call Control server (hereinafter referred to as a "Network Controller" (NC) ) performs the role of DSP service partitioning, quota enforcement, and resource load balancing to ensure that a DATS provider DSP can provide a high quality of service (availability, response time & consistent bandwidth) to subscribed DSPs and their end-users.  The Network Controller will assist in the Internet Data call establishment and tear-down, with the ability to refuse calls when the associated DSP has exceeded its service quota.  The network controller will also assist in the routing of calls to one of the DSP's Network Gateways (or data routers), using a load balancing scheme that maintains a pre-defined relative load on given DSP Network Gateways.  The Network Controller will also provide an implementation that supports Multilink Point-toPoint Protocol (MLP) and 56 kbps data calls for ISDN BRI access. Additionally, the Network Controller will perform such functions as statistics collection, and network element administrative control.  Finally, the Network Controller can be positioned to provide similar service control functionality with higher speed access technologies such as Assymetric Digital Subscriber Loop (ADSL) and high-speed cable modems.
