Abstract: There is proposed a novel furrow opening apparatus (10) that includes toothed discs (12 and 14) that are able to penetrate the soil thereby creating a furrow (114). The teeth (20) of the apparatus (10) are configured to prevent hair pinning of plant material within the furrow (114). The edges of the teeth (20) slice any plant material as teeth (20) penetrate the soil. Uncut straw is wedged between the teeth (20) and broken by tension as the discs (12 and 14) diverge and any uncut straw is removed from the furrow (114) by teeth (20). Any soil and plant material that adheres to the teeth (20) is cleared by a scraper (48) and deposited back on the soil surface. The apparatus (10) may further include a seeding device (142) that is configured to follow the toothed discs (12 and 14) and create a seeding furrow (166).

Abstract: A project management system for development of land is provided. An embodiment includes a project management engine interconnecting a plurality of workstations. Users at each workstation can select lots on a subdivision proposal. When the project management engine determines a sufficient number of lots are selected, provision of services for those lots commences in conjunction with a second project management engine.

Abstract: The invention provides a process and anal seal for sealing the anus of the carcass (10) of a slaughtered animal. The anal seal includes a plug (15) for insertion through the anus so that tissues (11) contract behind the plug, a clamp (20) movable towards the plug to clamp the tissues behind, and retaining means (40) to hold the clamp in its clamping position. The plug (15) is conical and has a back end (17) so that the clamp which is in the shape of a clamping disc (22) clamps against periphery (18) of the back end of the plug. The clamp (15) can slide on a stem (32) extending from the back end of the plug. The retaining means (40) can comprise biasing means (48) or a latch (41) to hold the clamp in its clamping position. An applicator tool (60) can mount the anal seal during insertion of the plug into the rectum and move the clamp from a retracted position to its operative clamping position.
