Patent CA-2217508-A1 (CA)
Title: Connector assembly
Inventor: D JURIC GORAN
IPC: F16L37/00
Filed: 1997-10-06
Abstract: A connector assembly comprising a retainer mounted axially to tubing, conduit, rod, cable or other axially loaded components behind a male insert having an annular ring or bead or an expanded end portion. Upon assembly of the male insert and retainer into a female receptor, the retainer arm's spring extensions compress to permit entry into the female receptor and once past an annular protrusion in the receptor, resume their normal state. This prevents the female receptor and the male insert from disengaging by the interference between the annular ring, the annular protrusion and the retainer arms and also prevents debris from entering into the joint connection, thereby affecting the operation of the retainer and any sealing means.

Patent CA-2221829-A1 (CA)
Title: Method for protecting software
Inventor: UMKEHRER ALFRED
IPC: G06F21/22
Filed: 1997-11-21
Abstract: For safe-guarding that a software package produced by a manufacturer can be used only by someone acquiring it together with an individual device ((g1;gz) of the same manufacturer and for inhibiting the device owner to acquire further devices of the same type without assuming the obligation of also having to acquire the software package which is necessary for each further device, the following software protecting method is disclosed: The software (sw) is installed in a computer (pc) of the owner. Each device (g1;gz) is assigned by the manufacturer an individual identification word (iw1;iwz) which differs from the respective identification words of all the other devices. This word is stored in a nonvolatile memory (m1;mz) of the device. By means of a processor (pz), a key word (kw1;kwz) is formed by the manufacturer from the identification word (iw1;iwz) using an encryption algorithm and the key word is stored in the memory (m1;mz) of the device. The identification words are listed, together with the associated key word, in a database (dbb) of the device owner and in a database (dbh) of the software manufacturer. Whenever one of the devices is started up the software checks, whether the identification word stored in its memory is present in the owner database and, if so, whether the key word associated with this identification word is present in the owner database, if the identification word is not present therein, whether a correct key word is stored in the device memory. If so, the software stores the key word and the associated identification word in the owner database and enables the electronic control of the device. If not so, the software creates an error list of those identification words with which an incorrect key word is associated and does not enable the electronic control of the device.

Title: Apparatus and method for redundant write removal
Inventor: STILES IAN J
IPC: G06F13/00
Filed: 1996-06-20
Abstract: A method and apparatus for combining writes and avoiding redundant writes are disclosed. Based on values such as overhead message size, largest message size, packet round trip time, cache block size, dirty cache region size and separation, channel throughput, and the identity of cached data values, a write region (60) containing cached data (68) is selected and (if non-empty) is written across the network (10). Depending on conditions, the selected write region includes either two dirty regions (62, 68) and an intervening clean region (70) or only one dirty region. In the latter case, the other dirty region is flushed by a subsequent write operation. The goals of avoiding network congestion, updating the cache promptly, and utilizing available network bandwidth are balanced according to conditions in the cache (60) and on the network (10).

Patent CA-2228646-A1 (CA)
Title: Method and apparatus for controlled small-charge blasting of hard rock and concrete by explosive pressurization of the bottom of a drill hole
Inventor: WATSON JOHN DAVID
IPC: F42B3/00
Filed: 1996-08-02
Abstract: Rock and other hard materials, such as concrete, are fragmented by a controlled small-charge blasting process. The process is accomplished by pressurizing the bottom of a drill hole in such a way as to initiate and propagate a controlled fracture or propagate any pre-existing fractures near the hole bottom. A cartridge containing an explosive charge is inserted at the bottom of a short hole drilled in the rock. The explosive charge is configured to provide the desired pressure in the hole bottom, including, if desired, a strong shock spike at the hole bottom to enhance microfracturing. The cartridge is held in place or stemmed by a massive stemming bar of high-strength material such as steel. The explosive can be initiated in a variety of ways including by a standard electric blasting cap. The cartridge incorporates additional internal volume designed to control the application of pressure in the bottom hole volume by the detonating explosive. The primary method by which the high-pressure gases are contained in the hole bottom until relieved by the opening up of controlled fractures, is by the massive inertial stemming bar which blocks the flow of gas up the drill hole except for a small leak path between the stemming bar and the drill hole walls. This small leakage can be further reduced by design features of the cartridge and of the stemming bar. The stemming bar is preferably connected to a boom mounted on a carrier. A preferred embodiment incorporates an indexing mechanism to allow both a drill and a small-charge blasting apparatus to be used on the same boom for drilling and subsequent charge insertion and firing operations. The major features of the method and apparatus are the relatively low-energy of the flyrock and the relatively small amount of explosive required to break the rock.

IPC: D06C21/00
Filed: 1996-09-13
Abstract: A mechanical compressive shrinkage machine, especially for tubular and open width knitted fabrics, and of the type comprising feeding (11) and retarding (12) rollers cooperating with entry side (18) and exit (35) blades forming a compressive shrinkage zone between the rollers, is provided with novel and improved adjusting mechanisms. For each of the blades, there is a separate adjusting mechanism, each comprising, at each side of the machine, an in-line fluid cylinder (50, 70), a technician-accessible independent adjustment, and a rotatable eccentric (54, 74). The rotatable eccentrics on each side are carried by a common shaft (55, 75), which is accessible externally and provides an operator-controlled adjustment. The limits of production operator control are such, by design of the eccentric portions of the shaft, as to be within a safe range, to avoid damage of the equipment through careless operator action. The in-line fluid actuators, incorporated into the adjustment linkage, enable rapid, gross movement of the elements for the purpose of reconfiguring the machine in a wide open condition for cleanout.

Patent CA-2249154-A1 (CA)
Inventor: CRUICKSHANK BRIAN
IPC: H04M7/00
Filed: 1998-09-30
Abstract: To reduce telephone toll costs to a user, a PBX preferentially establishes a call to a destination number (DN) over a WAN or the internet. The PBX determines the available connection types available by querying look-up tables for the particular DN. If no alternatives to the PSTN are available, the call is routed over the PSTN. Where a WAN or internet connection is available, the call is then routed over this alternative service. If the Quality of Service (QoS) over the computer network connection falls below a specified threshold, a second parallel connection is made over the PSTN and the call is then transferred to the PSTN. The user is notified of this change in service. During the PSTN connection, the PBX polls the alternative service and, upon the QoS rising above a specified threshold, the call is then routed back to the alternative service and the PSTN connection is torn down. The user is again notified of this change in service.
