Abstract: A ground-engaging paired row furrow forming tool includes a tool body having fore and aft ends with an outer edge defined on each of two opposing sides of the tool body. A furrowing wing is located adjacent each of the opposing sides and protrudes from bottom portions of the tool body. The tool body has lower surfaces including a central front surface portion which is angled upwards towards the fore end and a center passage is defined between the furrowing wings. This passageway is in part defined by a central rear surface portion which is adapted to be substantially aligned fore to aft in a direction of travel T during operation of the ground engaging tool. This paired row opener works well without compromise in a broad range of soil conditions without fouling and enables planting of seed rows spaced widely apart while minimizing soil surface disturbance.

Abstract: An injection mold for use with a molding press has four mold levels in axially stacked relation, permitting a substantial doubling of output for a given size of press as compared with a back-to-back two level stacked mold. The mold feeder flow path extends axially from the injector head to a flow distribution block located at the centre of the stacked mold block series. The centrally located distribution block is connected, in use isolation, sealed relation with the injector head, being axially displaceable therefrom in contin-uing sealed relation upon the opening of the mold. A drool prevention valve system, located at two of the mold inter-faces, to preclude drooling of fluid plastic stock upon open-ing of the molds includes pressure fluid actuators for operat-ing the valves, wherein the pressure fluid may comprise the fluid plastic stock. The valve system also includes a de-pressurizing valve provision, wherein, upon opening of the mold interfaces the stock distribution passages are substan-tially depressurized, to thereby reduce any tendency to drool.      The mold includes axial adjustment means to compensate for differential variations in overall mold length within the press, due to changes in effective mold temperature.

Abstract: A wearable, self-contained drug infusion device is disclosed that achieves the precise flow rate control needed for dose critical drugs. Valve or pump structures may be used with thermal flow sensors and closed-loop control circuits for providing the desired flow rate control. The device may have a two-part construction, where the electronic components are housed in a reusable portion and the fluid delivery components are housed in a separable disposable portion. This reduces the effective cost of the device to the user, assures sterility of the drug, and prevents fluid communication of the reusable portion by confining the fluid flow path to the disposable portion. The invention may include a wireless unit for controlling the operation of the drug infusion device. The wireless unit may communicate with the reusable portion using radio frequency (RF) methods, optical infrared (IR) methods, or other methods.
