Abstract: A boar cart (10) for carrying a boar through alleyways of a sow insemination area for interaction with the sows during insemination is formed by a cage for containing the boar including a cage floor (17) on which the boar stands, two sides (50,51) each defined by vertical bars on a respective side of a longitudinal center line of the cage assembly for confining the boar so that the boar is maintained extending longitudinally of the cage, a front (52) and a rear (53) defined by vertical bars, at least one of which can be opened as a door to allow entry and exit.  The cage is mounted on rear driving wheels (22) and front steering/caster wheels (35,36). The cage is defined by a front portion (12) and a rear portion (11) connected together for pivotal articulated movement about one or two pivot couplings defining a vertical pivot axis (13) arranged substantially at the center line such that the cage can articulate to the left and to the right for navigating left and right corners in the alleyways while the boar is retained in the cage. The length of the cage is reduced by bowing the front and rear bars. The front steering wheels (35,36) can be set to direct the steering slightly to the left or right so as to tend to guide the cage along one or other side of the alley where it has rollers (43,44) to run along a rail and hold the boar close to the sows on one side.

Title: Method of blasting rock using air tubes charged in a blasthole
Inventor: KANG DAE WOO
IPC: F42D1/00
Filed: 2000-02-16
Granted: 2002-09-17
Abstract: A rock blasting method is provided in which a series of aligned boreholes a re charged with explosives and air tubes in a predetermined pattern. The air tu be is a cylindrical flexible tube having a predetermined width and length to be fitt ed with the borehole. In one preferred form, each borehole is charged with the explosives and detonator with one air tube installed above the explosives. A stemming material is installed above the air tube. For example, in a 45-millimeter diameter an d 2.5 meter long borehole, the length of explosive charging is 0.8 meters, the co- operating charge weight was 0.648 Kg, the total amount of explosives 3.24 Kg, the leng th of the air tube 1.0 meter, the diameter of air tube 40 millimeters, and the length of stemming 0.7 meters. The explosives and air tube may be alternately charged along the borehole. The use of air tubes, charged above at least one explosive lay er allows a quantitative air decking in every blasthole. A reduction in detonation velocity and noise is observed in the field test. Also, the air-deck effect can be easily  obtained: an increase in fragmentation rate with minimizing the production of boulders. A reduction in explosive usage is also achieved.

Abstract: A local area network using the telephone wiring within a residence or other building simultaneously with telephony signals. The local area network uses high pass filters to access the high- frequency band across the media, whereas the standard telephone service uses low pass filters to access the low-frequency voice / analog telephony band across the same media. The elec-trically-conducting media connecting telephone / data outlets are split , or separated at each outlet, and the outlets are modified to provide access to both ends of the resulting segments. The low pass filters at each segment end join the segments together, allowing analog telephony signals to travel throughout the network, thus supporting normal telephone service. The high pass filters at each segment end are connected to modems or other Data Communication Equipment, thus supporting data communication networks of various topologies, including point-to-point topologies.
