Title: Method and apparatus for concealing the enablement of a device by modifying a status word
Inventor: JERRIM JOHN W
IPC: G06F13/00
Filed: 1990-09-17
Granted: 2000-01-25
Abstract: A status word modification device. A serial communications device (11) contains two universal asynchronous receiver transmitters (UARTs) (14, 15). Each DART contains a first in, first out (FIFO) buffer (14a), two status buffers (14b, 14c), and a FIFO control register (14d). If the applications program in the host (10) is an enhanced application program which supports the use of the FIFO buffer (14a), then the program will cause FIFO enablement instructions to be written into the control register (14d). In this case, the interface circuit (22) allows the status words to pass unaltered whenever the host (10) reads the status buffers (14b, 14c). However, if the applications program is a standard applications program which does not support the use of the FIFO buffer (14a), then the program will not write to the control register (14d). In this case, the interface circuit (22) will alter the value of selected bits of the status words if the user has enabled the FIFO buffer (14a) and the host reads the status buffers (14b, 14c). The alteration of the status word prevents the standard applications program from treating the FIFO-related bits in the status words as data errors.

Title: Automatic oiling device
Inventor: WILHELMSEN ARNE
IPC: F16N7/12
Filed: 1991-05-31
Granted: 1995-03-28
Abstract: An automatic oiling device for delivering oil to a bearing comprising a sealable container defining a reservoir for oil with a central opening in which a hollow tube is fitted.  One end of the hollow tube communicated with the interior of the sealable container and the other end is open.     Wicking material is located in the hollow tube and extends into the interior of the sealable container at one end and extends from the other open end of the hollow tube for contact with a bearing to be oiled.  The hollow tube and the wicking material co-operating to function as an automatic valve to release oil from the sealable container as needed by the bearing.  The wicking material is packed into the hollow tube to a density sufficient to allow for an automatic valving cycle that controls the flow of oil.  The automatic valving cycle involves capillary flow of the oil from the reservoir through the wicking material to the bearing, the flow of oil lowering pressure in the sealable container which eventually results in the capillary flow being curtailed, whereupon the lowered pressure in the sealable container is sufficient to draw air through the wicking material and into the sealable container to increase the pressure in the sealable container such that capillary flow resumes and the automatic valving cycle is repeated.

Title: Intensity dividing device
Inventor: JENKINS RICHARD MICHAEL
IPC: G02B6/28
Filed: 1991-12-02
Granted: 2002-11-26
Abstract: An intensity dividing device (10) incorporates a rectangular multimode waveguide (20) connected to an input waveguide (18) and a set of four output waveguides (22). The input waveguide (18) provides a fundamental mode input excitation of CO2 laser radiation to the multimode waveguide (20). The input waveguide (18) is offset from the multimode waveguide longit-udinal axis (24). Consequently, both symmetric and antisymmetric modes of the multimode waveguide (20) are excited. Mo-dal dispersion along the multimode waveguide produces electric field intensity maxima of differing magnitude centred on respective output waveguides (22). This provides division of the input radiation into a range of differing intensity outputs.

Title: Absorbent article with improved elasticated flaps
Inventor: PALUMBO GIANFRANCO
IPC: A61F13/15
Filed: 1992-07-28
Granted: 2002-10-01
Abstract: A disposable absorbent article such as a diaper provided with a continuous upper layer (5), an absorbent element (6), an impermeable plastics sheet (9), elastic parts (10) positioned along the lateral edges to either side of the absorbent element (6) and two elasticated flaps (11) positioned inwardly of the elastic parts (10). Each flap (11) is formed out of the continuous upper layer (5) by use of an elastic element (14) fixed along its entire length to the inner surface of the continuous layer (5). The continuous upper layer (5) is liquid-permeable in the zone between the two elastic elements (14) of the flaps (11) and impermeable in the two adjacent zones located between the elastic elements (14) and the lateral edges of the absorbent article. In use, the elastic elements (14) contract, lifting the continuous upper layer (5) off the underlying surface, at least at the crotch area, forming two longitudinal barriers which are impermeable on the side facing the lateral edges of the absorbent article, thus ensuring a more efficient con-tainment of lateral leakage of liquids and solids in an absorbent article of simplified structure.

Patent CA-2116720-C (CA)
Inventor: KAUFHOLD HORST T
IPC: B61G7/10
Filed: 1994-03-01
Granted: 1998-12-22
Abstract: A railway coupler system can include either a fixed or rotatable coupler, a yoke casting, a follower block, a draft gear. When a railcar is initially constructed, a small amount of controlled lateral movement in the coupler system components, known as controlled slack, is provided for ease of system installation. However, upon operable use, wearing of the coupling components will develop small gaps or spaces between components, known as free slack. When free slack initially develops, its growth is accumulatively accelerated, especially between the center sill side walls and the follower block side walls. This accumulative free slack development is the result of the harder cast steel follower block abrasively wearing its side walls against the construction grade steel center sill side walls. Means is attached to each of the follower block side walls in order to prevent metal-to-metal contact between the follower block side walls and the center sill side walls. The preventative means comprises an elastomeric wear pad attached to a base plate, a base plate being anchored to each of the follower block side walls. The pads are made of a softer, low-friction material, compared to the carbon steel side walls.          Since the elastomeric wear pads are softer than the center sill side walls, only the restrictive means will wear, thereby preventing destruction of the center sill side walls no matter how much slack has been developed in the coupling system. The structure is also adaptable to either E or F type couplers.

Title: Image scanner measuring the motion of reader and light source on a test chart
Inventor: IMAGAWA TAKASHI
IPC: H04N1/193
Filed: 1994-04-19
Granted: 1999-07-13
Abstract: A scanner is so arranged that a quantity of light reaching a CCD sensor can be kept constant with a change in reading position.  In cases where a light source and a reading optical unit are driven independent of each other, variations in feed amount inevitably occur.  To deal with it, a test chart of a specified length is first read to measure amounts of movement of the light source and the reading optical unit. Then, the reading optical unit is moved by a predetermined amount.  The light source is moved to effect a correction based on the amount of movement initially measured.  Then, a one-line reading process is carried out to scan an image on a document.
