Patent CA-2145266-C (CA)
Inventor: BOTTS CHARLES R
IPC: F16L55/10
Filed: 1995-03-22
Granted: 1999-10-12
Abstract: A device for holding an IV tube in a pumping apparatus and for selectively occluding the tube when the door of the pumping apparatus is opened, to prevent free flow of fluid in the tube.  The device consists of a base member to which the IV tube is attached or through which it passes, and a slide clamp which slides relative to the base member and relative to the tube.  The IV tube is passed through an elongated aperture in the slide clamp, and the slide clamp is slidingly mounted on the base member.  The aperture in the slide clamp has a relatively open hole at one end, through which the tube passes when the slide clamp is in one position, allowing fluid to flow through the tube.  The aperture also has a relatively constricted slot at the other end, through which the tube passes when the slide clamp  is  in a  second position,  preventing fluid flow through the tube.  A flexible cantilevered arm on the base interlocks with a locking projection on the slide clamp to lock the slide clamp in the second position to maintain the tube in the occluded state.   The door of the pumping apparatus interacts with the slide clamp to move the slide clamp from the first,  flowing position to the second, occluding position when the pumping apparatus is opened. The door also interacts with the slide clamp to move the slide  clamp  from  the occluding  position  to  the  open position when the door is shut.

Title: Method and system for establishing voice communications using a computer network
Inventor: DEZONNO ANTHONY J
IPC: H04L29/08
Filed: 1996-04-02
Granted: 2003-04-29
Abstract: A method and system (100) establishes voice communications between a computer operator (102) and an agent (104) of a business over a computer network, such as the Internet (108).      Using an operator computer (106), the computer operator (102) views advertisements of the business' products or services on the Internet (108) via customized home pages (200). When the operator (102) wishes to order a product or ask additional questions about a product, the operator (102) activates a "call me" button (210). A return call screen (300) is then presented to the operator (102) with areas to insert a name (302), a telephone number (304) and a time to call (306). This information is packetized in a call request which is transmitted over the Internet (108) to a telephone switching system (112) associated with the business. The telephone switching system (112) subsequently dials the telephone number (304) at the time to call (306). When the operator (102) answers an operator telephone (120), the telephone switching system (112) connects the operator (102) with the agent (104) via an agent telephone (118). The telephone switching system (112) may be comprised of a telephone computer (114) and an automatic call distributor (116).

Abstract: A system for feeding wood chips entrained in cooking liquor to a high pressure feeder connected to a continuous digester includes a vertical treatment (e.g. steaming) vessel, a metering device connected to the discharge from the steaming vessel, a generally vertical chip chute extending downwardly from the metering device, and a slurry pump having an inlet. The slurry pump pumps the slurry from an outlet thereof to a high pressure feeder low pressure inlet. In order to minimize the effect of changes in liquid volume upon the operation of the system, and to provide separate control of liquor volume and chip volume, a substantially vertical liquor tank having a top and bottom the bottom including a discharge opening above the slurry pump inlet is provided. A conduit directly connects the liquor tank discharge opening with the slurry pump inlet. A pressure isolating device may be used in the system if it is to operate at superatmospheric pressure rather than atmospheric pressure.

Title: Method and apparatus for decoding bar code symbols using independent bar and space analysis
Inventor: SMITH CHRISTOPHER E
IPC: G06K7/14
Filed: 1994-08-29
Granted: 2000-07-11
Abstract: A bar code reader decodes a bar code symbol, one character at a time, by analyzing the spaces of each character independently from the bars of each character. The reader determines the widths of each space and each bar. The reader then determines a space-width threshold based on the widths of the spaces and a bar-width threshold based on the widths of the bars. The reader then classifies each space as being either narrow or wide by comparing each space to the space-width threshold. The reader also classifies each bar as being either narrow or wide by comparing each bar to the bar-width threshold. The reader then decodes the character according to the narrow/wide classifications.

Abstract: A mask for use in delivering gas to a user and which accommodates relative movement of a connecting gas supply line. The mask has a face contacting portion which is shaped to define a chamber through which gas is delivered to the respiratory tract of the user and, in a preferred form of the mask, the face contacting portion is formed with a convex end region which is arranged in use of the mask to be depressed by and to accommodate facial features of the user. A gas supply port is formed integrally with a wall portion of the chamber and the port provides for connection of a supply of pressurised gas to the interior of the chamber. The mask is characterised in that the wall portion that contains the gas supply port is formed to exhibit a degree of flexibility that is greater than that of adjacent regions of the mask, whereby any movement that is referred to the mask by the connecting gas supply line will be accommodated, at least in part, by flexing the wall portion that contains the gas supply port.
