Title: Phosphine fumigation method and apparatus
Inventor: WINKS ROBERT GORDON
IPC: A23K3/00
Filed: 1990-06-25
Granted: 2000-08-08
Abstract: An economical, yet effective technique for fumigating grain and other particulate foodstuffs involves the continuous controlled passage through the grain or the like of a carrier gas containing phosphine. The concentration of the phosphine in the carrier gas is within the range of from 4 to 200 micrograms of phosphine per litre. The flow of the gas is at a constant linear velocity within the grain, and the gas leaves the grain mass at a velocity of from 0.5 x 10-4 to about 2 x 10-4 metres per second. This fumigation technique is applicable to the fumigation of grain in a storage facility having a plurality of grain silos (13) and a single source (10) of a gaseous fumigant. The single source of gaseous fumigant is connected, via a gas supply duct (11), to gas inlet ports of the silos. The connection between each gas inlet port and the duct is provided with a respective valve (14) and a respective orifice plate (15), which is adjusted so that the pressure drop across the plate into the silo is substantially greater than the pressure drop across any other component between the gas source and the silo.

Title: Restoration kit for communications cable
Inventor: ABERSON JAMES ASHLEY
IPC: G02B6/44
Filed: 1993-01-14
Granted: 1998-01-20
Abstract: In order to restore quickly service which has been interrupted by damage in at least a portion of a cable, ends of optical fibers on one side of a damage location are spliced to optical fiber end portions of a restoration cable (70) within first and second closures (22,23) of a restoration kit (20). The first closure is attached to a foamed polymeric mounting pad attached to one flange of a deployment reel (100) mounted rotatably on a payout spindle (135) which extends normally from one portion of a carrying case (21). Optical fibers of each end of the restoration cable are connected to splicing devices mounted in splicing modules (40,40) in the first and second closures. The second closure is moved from the case toward an opposite side of the damage location whereat fibers of the damaged cable on the other side of the damage location are extended into the second closure and spliced to the restoration cable therein. Because the first closure is attached to the deployment reel, the first closure turns with the reel as the reel is turned rotatably during payout of the restoration cable.

Title: Digital image processor for color image transmission
Inventor: FEIG EPHRAIM
IPC: G06T1/00
Filed: 1993-04-21
Granted: 1999-05-25
Abstract: The present invention improves either the processing speed or circuit complexity (or both) of a digital image processor by eliminating the conventional multiplication operation from the RGB to YUV and YUV to RGB transforms having NTSC compatible equation coefficients. In particular, the change of color-basis matrix for converting RGB data to obtain YUV data is factored into a scale factor and a coefficient matrix. The coefficient matrixcontains coefficients such that its product with the RGB input vector can be performed using only seven binary additions and five shirt operations. This process effectively removes the conventional multiplication operations from the RGB to YUV conversion. The scale factor is conveniently absorbed into the quantization of the YUV data before transmission. The quantization process includes a multiplication already and the two multiplication steps are folded into one step. Therefore, the absorption of the scale factor into the quantization step does not increase the processing time because no multiplication steps are added. This process of factoring the transform matrix is also applied to the inverse transform process. In the inverse transform process the change of color-basis matrix for converting YUV data to RGB data is such that its implementation reduced to five addition steps and two shift steps, again effectively eliminating the conventional multiplication operations. Also, the diagonal matrix is absorbed into the descaling process so that no multiplication steps are added to the inverse transform process.

The molten polymer is extruded and blown out of the die heads by high-velocity hot air to form two or more layers of melt blown fiber webs. The webs tend to extend to join together and a certain angle B exists between the extending directions of the webs. In the same time, the pre-equalized feather and/or down  is blown out of down slot jet positioned between the die heads in the laminated state and sandwiched and wrapped by the melt blown fiber webs.  Said fiber webs and said feather and/or down blown out of the feather and/or down slot jet twine and stick together randomly and they are condensed,  and collected on the receiving device to form the melt blown composite feather and/or down madding.

Abstract: A simulcast system capable of synchronizing and main-taining synchronization of a plurality of base sites (1602, 1604 1606, 1608). The base sites (1602, 1604, 1606, 1608) are cap-able of transmitting data at substantially the same time. A gen-erator generates time marks ( 1708) at a predetermined time pe-riod(T). A data divider (1812) divides packets to be interposed between at least a pair of time marks. The data packets (1704) and time marks (1708) are transmitted to the base sites. The base sites include base site receivers (1603, 1605, 1607, 1609) for receiving the data packets and time marks and clocks (1611, 1613, 1615, 1617) for measuring the time (T) between each pair of time marks. Base sites controllers (1612, 1614 1616, 1618) determine the variations in time between any pair of time marks and the predetermined time period (T). Timers adjust the delay time at each of the base sites in response to the variations at each corresponding base site, and delay re-transmission of data by a predetermined delay time for each of the base sites to enable the retransmission of data at sub-stantially the same time.

Abstract: An electrical control apparatus for the air bag system capable of inhibiting the diagnosis of back-up capacitors when a diagnosing routine is initiated by an extraneous noise. In a main routine executed by a microcomputer provided in an electrical control apparatus for an air-bag system, data stored in a specific address of a volatile memory is read out, and it is determined whether or not its value is the same as a fixed value. If the result is affirmative, it is determined that the main routine is started by an extraneous noise, an ignition flag IG is reset, and the diagnosis of the back-up capacitors is inhibited. On the other hand, if the data does not have the same value as the fixed value, it is determined that the ignition switch is turned on again after it has been turned off, the IG is set, and the diagnosis for back-up capacitors is carried out.

Abstract: An improved access control apparatus, method, and system are disclosed to enhance the security of information in cards of the type having data storage and functions which are not accessible without verification of the identity and the authority of a person requesting access. The card need not include identification information for others that may require access to information in a person's card. Several authorization profiles are provided in a card, but there is no need that a profile be identified to any one person in order that they each may perform required tasks using or adding information in another person's card. The identification card of a supervisor or doctor who requires access to another person's card contains secret information Xsup identifying the supervisor or doctor as having the authority of supervisor or physician and an encryption key. The secret authorization information is encrypted and transmitted through the reader to the other person's card where it is decrypted and compared with the X'sup secret value stored in the other person's card. If they agree, the supervisor is permitted to perform functions authorized to be performed by supervisors in accordance with the profile for supervisors in the other person's card. Each supervisor is identified by a supervisor's own card using a password, PIN, or biometrics that may be changed as often as desired without recalling the cards of others for update. The authorization information is not exposed outside of a secure environment.      Therefore, unlike PINS which are exposed during entry, it need not be changed or updated during the life of the card.
