Patent CA-2178981-C (CA)
Title: Heat exchanger and heat pump circuit
Inventor: AMBS REX K
IPC: F25B30/06
Filed: 1996-06-14
Granted: 2000-01-11
Abstract: A heat exchanger and heat pump circuit having an operating subcircuit and a pump down subcircuit each including a liquid line and a heat transfer tube. The heat transfer tube of the pump down subcircuit surrounds the liquid line of the operating subcircuit. During the heating cycle, the heat pump circuit circulates refrigerant through both subcircuits to abstract heat from the heat source/sink. However, during the cooling cycle, the heat pump circuit circulates refrigerant only through the operating subcircuit. Also during the cooling cycle, the heat pump circuit places the pump down subcircuit at low pressure to thermally insulate the operating subcircuit liquid line.

Abstract: Down pressure-structure for providing an adjustable down force on a rig of row crop implement such as a cultivator includes an overcenter toggle connected to the rig for pivoting about a toggle axis between a first and second positions.  The toggle has a protrusion that contacts the edge of a rig plate at two different locations corresponding to a light and a heavy down pressure position.  A down pressure spring is tensioned between the frame and the toggle and maintains the toggle in a selected one of two overcenter positions corresponding to the two different spring tension positions.  A hex projection on the toggle receives a conventional wrench for moving the toggle between the first and second positions.  A second toggle and down pressure spring combination provide additional spring adjustments so that at a numerous easily determinable down pressure settings are available.
Patent CA-2183286-C (CA)
Inventor: FLOCKHART ANDREW DEREK
IPC: H04Q3/545
Filed: 1996-08-14
Granted: 2000-08-08
Abstract: A call-center ACD switch (105) is modified to respond to an arriving call by determining, for those splits (110-111, 106-109) that could handle the call, the present values of a parameter that defines what is a best split for handling the call, determining from those present values which one of the splits is the best split for handling the call, and then enqueuing the call in the call queue of the best split. Alternatively, the call-center ACD switch is modified to respond to a call that overflows the call queue (130) of its primary agent split (110) by determining which one of the backup splits (111, 106-109) in which call center (143-145) is the best backup split for the call, and enqueuing the call in the call queue of the best backup split. Any desirable criterion or criteria may be used to determine which split is best for the call. A preferred criterion is queue waiting time: the best split is the one whose call queue offers the shortest in-queue waiting time. The waiting time may be either the real estimated waiting time (EWT), or the EWT weighted for other factors (WEWT) -- the cost of facilities involved in connecting the call to the split's corresponding queue, for example, or a desire to retain the call for the preferred split unless its waiting time can be improved elsewhere by a predetermined minimum amount. A queuing control function (207) is implemented as an an administratively-programmable executable script, and it directs the ACD switch to obtain, for each call, the EWTs of the splits, to weight these EWTs in order to obtain the corresponding WEWTs, to compare the WEWTs with each other in order to find the split with the shortest WEWT (the best backup split), and then to enqueue the call in the queue of this best split.

Title: Network access to internet and stored multimedia services from a terminal supporting the h.320 protocol
Inventor: BRUNO RICHARD FRANK
IPC: H04L29/06
Filed: 1996-08-27
Granted: 1999-10-05
Abstract: Internet access is provided to a multimedia terminal (101, 102, 103, 104) supporting the H.320 protocol through a gateway server (125) that is connected to the Internet. The data stream of the H.320 bearer channel (ISDN phone line or switched 56 kbps facilities) is used for the exchange of data between the accessing terminal and the gateway server, which outputs and receives such data onto and from the Internet, respectively. The gateway server is implemented to function to directly exchange on the H.320 data stream information requests and responsive data in the TCP/IP format used for Internet transport. Alternatively, the gateway server is implemented to function as a proxy to which requests are passed from the terminal over the H.320 data stream, and where function calls are made and locally converted to TCP/IP format for transport onto the Internet. For responsive data received from the Internet, the proxy gateway server removes the TCP/IP formatting and transmits the resultant data back to the terminal over the H.320 data stream.

An axial extension of the layers extends beyond an end of the wire and along the exterior of the second section. The ferrule is mounted on the hose end and extends around an end section of the wire and the axial extension of the layers which are clamped between the ferrule and the end fitting.

Title: Improvements in or relating to call handling
Inventor: UKENA RICHARD
IPC: H04M3/436
Filed: 1997-06-30
Granted: 2007-06-12
Abstract: A method for routing a call to a called party who may be located at any one of plural sites which avoids delays in connecting the called party to the received call. When a call is received at a switch, a controller at the switch uses an embedded data base to identify plural sites where the called party may be located from among a multiplicity of sites to which the switch can be connected and causes the switch to initiate parallel connections from the switch to the identified sites. Another method of operating a telephone system in which a called party receives a telephone call from a calling party which is not to be answered and in which the called party is free to use its telephone while continuing to provide a ring signal to the calling party. Upon receipt of one or more rings at the called party's telephone, one or more key strokes are entered at the called party's telephone to provide a refusal signal to the telephone system which is providing a ring signal to the calling party. A further method of routing an incoming telephone call to a called party having plural telephone numbers in which a telephone call for the called party is received at a switching system, and automatically screened to determine where the received call is to be routed among plural devices with different telephone numbers for accessing the called party, where the devices may include a wireless telephone and a pager.

Abstract: An intravaginal set and a method of treatment of prolaps of urogenital organs and urinary stress incontinence or in the period of intervals in women when the intravaginal therapeutic insert for treatment of static disorders of the urogenital organs and urinary stress incontinence is not currently inserted, said method being realised by means of an intravaginal set of inserts, characterized by selecting the appropriate size of corrective insert from a subset of intravaginal corrective inserts, consisting of at least two balls with step increase in diameter, ranging between the minimal and maximal woman vaginal diameter, each ball being preferably hollow, each ball has the loosely hanging string and each ball is made preferably of medical material, such as polycarbonate or methyl methacrylate, said selecting being realised by means of an intravaginal measuring subset comprising at least two metal or plastic balls having graduated diameters corresponding to graduated diameters of the balls from the subset of the intravaginal corrective inserts, which balls instead of the loosely hanging string have a rigidly mounted linearly scaled slat for measurement of optimal diameter and depth of localization of the corrective insert in the vagina, depending on actual and individual anatomical conditions of urogenital organ of the woman being treated, by the selection of appropriate optimal diameter and depth of localization of the corrective insert in vagina by approximations with using the balls from the measuring subset, so that contraction of the levator ani muscle will cause the elevation of the insert and the elevation of the insert will cause the elevation of the uterus and/or correction of the cysto-urethral angle, and during the progress of said treatment the sizes of successive applied corrective inserts are adjusted by analogic selection of appropriate optimal diameter and depth of localization of the measuring ball in the vagina, and advantageously by carrying out the exercises of the pelvic floor muscles of treated woman lying in prone or genucubital position in the intervals between successive replacements of the corrective inserts.
