Patent CA-2092297-A1 (CA)
Inventor: HALE MICHAEL ANTHONY
IPC: H04B10/08
Filed: 1991-10-17
Abstract: A head-end station (1) for a passive optical network system arranged to transmit and receive TDMA frames comprising a header portion and a plurality of basic frames, each basic frame comprising traffic bits and control bits. The head-end station (1) includes a data transmitter which assembles and transmits downstream frames and also generates a diagnostic signal for transmission in a downstream frame, the station being switchable to a diagnostic mode in which it transmits the diagnostic signal in a downstream frame in the absence of other traffic, and also including a data receiver which receives upstream frames and detects a return of the diagnostic signal. In a preferred example, the head-end station (1) may transmit a diagnostic signal in the header portion (H) of each downstream frame. Also, in a test mode the transmit signal is looped back to the receiver to enable testing of the transmit/receive function. Loop back is provided at three levels, namely the transmitter drive level, the monitored output level and at the laser output/receiver input level.

Title: Office panel element configuration
Inventor: HELLWIG JOHN
IPC: E04B2/74
Filed: 1993-05-04
Abstract: ABSTRACT OF THE DISCLOSURE         An element of an office panel includes a back support member closed at either end by molded end pieces. The molded end pieces in combination with the back support member define a front opening recess into which a filler material is inserted.  A decorative facing material is applied over the filler material and attached to the back support member and the molded end pieces, whereby the facing material forms a finish face of the element.  With this arrangement, the back support member is more easily manufactured, as it is open at either end and the molded end pieces can easily be inserted within the back support member to effectively close the member and provide a complete support for the element.  According to an aspect of the invention, the molded end pieces include molded components thereon by means of which the element can be effectively supported by an office panel frame.

Patent CA-2108964-A1 (CA)
Title: Gabion system
Inventor: PILDYSH MIKHAIL
IPC: E02D29/02
Filed: 1993-10-21
Abstract: In general, conventional gabions include metal baskets filled with rocks.  These structures have several drawbacks including the susceptibility to destruction of the baskets under ice exposure conditions.  Other systems include concrete slabs with horizontal tie backs or vertical concrete slabs hinged between poles or columns attached to a basket formed of synthetic material filled with rocks.   The drawbacks of these systems include the requirement for labour intensive earthwork and heavy compacting equipment, and the expensive components.  A simple gabion which avoids the above problems includes a lightweight, polymeric concrete panel and a basket defined by a flexible mesh sheet, at least the ends of which are embedded in and retained by the panel for reinforcing the panel, the sheet extending from the end of the panel and defining a closed loop with the panel for receiving fill, whereby similar baskets can be stacked on each other to form a retaining wall.  The polymeric concrete mixture used in the gabion (and for other uses) includes approximately 16.9 to 24.04 weight percent portland cement, approximately 59.0 to 72.1 weight percent expanded shale or clay, approximately 5.5 to 13.0 weight percent water, approximately 3.3 to 7.4 weight percent polymer, and approximately 0.21 to 0.32 weight percent superplasticizer.

Abstract: The present invention provides a data processing system of the type which allows models of objects to be processed by interaction with an image representing the object in order to manipulate the model data; a method of operation a data processing  system  is  also provided.  The data processing system of the invention comprises a display device,  entry means for enabling a user to enter data representing lines or surfaces of a model,  such model data being stored in a storage device, and a retrieval means for retrieving model data  from  the  storage  device  and  displaying  the  image represented by such model data on a screen of the display device. The system is characterized by the combination of: a hand-held pointing device  adapted to  cooperate with the screen, for enabling the user to engage a particular point of the screen; a registering means for registering when the pointing device is engaging the screen and for determining the  particular  point  of  the  screen  that  is  engaged; association means for associating details of the particular point of the screen engaged with a corresponding point in the model data;  and a processor,  responsive to input from said  registering  means,   for  repetitively  applying  a smoothing function to the model data while the registering means indicates that the pointing device is engaging the screen,  the model  data  as  smoothed being  stored in the storage  device  after  each  application  of  the  smoothing function.  The  processor  is  further  responsive  to  the association means for adapting the  smoothing function so that its smoothing effect on a particular bit of model data is dependent on a distance measure between that particular bit of model data and the point in the model data identified by the association means. The retrieval means is employed to update the image on the screen at predetermined intervals with a new image representative of the new smoothed data.

Inventor: SIMPSON BRET A
IPC: B65B9/13
Filed: 1994-03-11
Abstract: An apparatus for compressing and containing a material in an elastomeric net (26). The apparatus comprises a compression chamber (12), a material compressor (16), a holding chamber (18), a net expansion and placement mechanism (42), and a bale advance mechanism (20). The material compressor is coupled to the compression chamber to compress a selected amount of the fibrous material in a direction transverse to the general lay of the material within the compression chamber to form a compacted bale (10). The holding chamber has an outlet and an inlet coupled to the compression chamber. The holding chamber also has an axis defined by a line extending between the center of the inlet to the center of the outlet. The net expansion and placement mechanism is for receiving the net, stretching the net to obtain a cross-sectional shape that is slightly larger than that of the holding chamber, and placing the net over the holding chamber with one end of the net slightly extending beyond the outlet. The bale advance mechanism is coupled to the holding chamber and compression chamber. Its function is to advance the bale from the compression chamber to the holding chamber and through the holding chamber outlet such that the bale contacts the end of the net that extends beyond the outlet and pulls the net onto the bale when the bale advances through the outlet.
