Title: Protective refractory shield for a gasifier
Inventor: BROOKER DONALD D
IPC: C10J3/46
Filed: 1999-07-28
Abstract: The protective refractory shield (10) for a gasifier includes a refractory attachment (70, 140) that is mechanically secured to a protectable surface (60) of the gasifier. The refractory attachment (70, 140) includes a plurality of attachment members (70, 140) of predetermined angular sector. The refractory attachment (70, 140) is provided to cover a downwardly facing horizontal surface (60) of the gasifier or to be positioned upon a vertical surface thereof. Latching means for the attachment include a projecting formation that projects from the protectable surface (60) that engages a complementary shaped recess in the attachment (70, 140) to mechanically secure the attachment to the protectable surface (60). The latching means do not form recesses in the protectable surface (60) nor do the refractory attachments (70, 140) form recesses in the protectable surface (60). Thus the integrity of the protectable surface (60) is maintained while it is protected.

Patent CA-2345645-A1 (CA)
Inventor: ANDERSEN MORTEN KJELDSEN
IPC: H04M1/02
Filed: 1999-10-04
Abstract: An electroacoutic communications unit with a receiver transducer in a housin g. The communications unit has accoustic connections both from the front side o f the diaphragm of the transducer and from its rear side to the area inwardly of the face of the unit for engagement with a user's ear as well as to the area  outwardly of this engagement face. These four acoustic connections constitut e the four branches of an acoustic balance bridge with the transducer as a generator. This configuration is particularly expedient, as it is hereby possible to reduce the inner air volume in the communications unit behind th e diaphragm of the transducer to a size which is without importance for the si ze of the telephone in practice. Furthermore, variations in the degree of tightness of the engagement of the communications unit with the user's ear will only influence the frequency characteristic to a very limited degree.</ SDOAB>
Patent CA-2345690-A1 (CA)
Title: Improved pushbutton lock
Inventor: BURLEIGH CHARLES E
IPC: E05B37/00
Filed: 1999-09-30
Abstract: Various enhancements are provided to a pushbutton lock to enhance its security. One is the provision of button tips that are mounted on the ends of the button assemblies and spring-loaded to protrude from the face of the lock, regardless of whether the underlying button is "in" or "out". By this arrangement, a bystander cannot readily see the button combination by the pattern of depressed buttons. This arrangement also reduces tactile feedback between the underlying button assembly and the externally available button tips, increasing resistance to pick attacks. A further enhancement is the provision of button bars between adjacent pairs of button tips. Whenever any of the button tips is manually depressed, the corresponding button bar is pressed into engagement with, and prevents movement of, a member that must be moved in order to unlock the lock. This arrangement further increases lock security by preventing an attacker from experimentally pressing buttons and judging the tactile effect thereon in attempted unlockings of the lock.

Patent CA-2352224-A1 (CA)
Title: A method and a circuit for retiming a digital data signal
Inventor: CHRISTENSEN STEEN BAK
IPC: H03L7/087
Filed: 1999-11-23
Abstract: By application of a method and a circuit for retiming a digital data signal (Din) consisting of a number of successive bits, wherein the data signal is sampled by an internal clock signal (Ckint) generated from an external clock signal (Ckref), the internal clock signal (Ckint) is phase locked to the data signal (Din) so that the latter is sampled approximately in the centre of every bit. By generating the internal clock signal from the external clock signal, and at the same time phase locking it to the dta signal, the internal clock signal will automatically adjust itself so that the data signal is sampled at the appropriate point in time, i.e. in the centre of the bit period. As a result, there are no strict requirements as to the synchronisation between the data signal and the clock signal, and an individual adjustment of the synchronisation in preceding circuits is thus avoided.

Title: Low vision panning and zooming device
Inventor: BETTINARDI EDWARD R
IPC: G06T3/40
Filed: 2000-04-05
Abstract: Disclosed are several embodiments of panning and zooming devices that may assist individuals with low vision. The present invention employs imaging devices that capture an image and then select a smaller portion of the image for full display. The size of the selected portion of the captured image determines the magnification that is achieved. Further, different portions of the captured image can be selected to provide for panning of the image. In this fashion, a stationary mounted camera can be used which allows an image to be both panned and zoomed. Further, automated techniques can be used for panning and zooming control. Small aperture optics are used so that images can be focused for a large depth of field which allows the present invention to be employed without the necessity for using expensive optical focusing techniques. Also disclosed is an electronic telescope/microscope that provides a bright image that can be zoomed to provide different magnifications. Another embodiment utilizes eyewear having displays mounted in front of the users' eyes and a camera mounted on the eyewear.
