摘要:
An apparatus for extracting organic compounds from plant materials using subcritical or supercritical carbon dioxide is described. The apparatus has a sealable pressure chamber into which carbon dioxide dry ice and the plant materials are inserted, the pressure chamber, once sealed, self-pressurizing as the container and contents are warmed to a chosen temperature, converting the solid CO2 to liquid, or to a super-critical fluid as the temperature and pressure are raised above the Critical Point. The chamber can be rotated when subcritical CO2 liquid is employed to improve mixing between the liquid and the plant material. After a suitable extraction time, the carbon dioxide solvent containing the extracted material is directed into a separator such that the carbon dioxide and extracted material can be effectively separated, thereby avoiding significant quantities of viscous and waxy extracted materials remaining in the chamber and valves after the carbon dioxide solvent is warmed and allowed to exit the chamber.

A device for marking a location. The device coming in two separate pieces, namely a ground stake and a marking post. The ground stake configured for insertion into a ground surface. The marking post configured for attachment to the ground stake. The post is preferably removable from the stake so that when livestock are present, if they uproot or displace the marking post portion of the device, the ground stake remains in the ground still marking the location. If a survey crew or other individual is at the marking location after the post has been removed, they can replace the post (or insert a replacement post) to return the device to its full functionality.

A towline fuse device for use in a towing system with a towing vehicle and a towline is provided. The towline fuse device comprises a fuse mechanism for failing at a predetermined level of tensile force, the fuse mechanism mounted between the towing vehicle and the towline wherein the predetermined level of failure of the fuse mechanism is less than the towing ratings of the towing system. The strain energy in the towline is then harmlessly dissipated in the towline fuse device.

During the process of binding a bale of crop material with binding twine in a crop baler, malfunction of the knotter is checked once upon completion of the binding sequence for one bale, and then a second time after the twine has been prepared by the knotter for formation of the next bale. The monitoring system is particularly appropriate for a double knotting mechanism in which each knotter operates through two complete operating cycles during each actuation thereof, a first cycle to complete a knot associated with the just finished bale, and a second cycle to complete a knot in two separate strands of twine to prepare the same for the next successive bale. The position of a slack takeup arm moved by the binding twine between a number of positions during the double knotting sequence is monitored by the electronic portion of the system, including a computer, so that if the takeup arm is located improperly at one of the critical checking times in the sequence, such condition is reported to the operator through a visual display in the tractor which tows the baler.

A combustion apparatus has an exhaust system, a fuel-supply system, and an air-supply system. The ratio of fuel-to-air supplied to the apparatus is adjustable in either direction in response to control information. A temperature signal is developed which has a value proportional to the combustion-produced temperature. A first sample of that temperature signal selected during a first time interval is compared with a second sample of the temperature signal developed during a later time interval. The comparison serves to produce the control information that causes adjustment of the fuel-to-air ratio in the direction seeking a maximum of combustion-produced temperature. Digital logic circuitry is specifically utilized for the purpose of producing the desired control information.

Bales emanating from the discharge end of a baler are received on an accumulating trailer provided with a weighing scale that, in combination with an electrical system, automatically determines the weight of certain of the successively issuing bales and conveniently displays such weight to the operator in the cab of the towing vehicle so that the operator can monitor the quality and condition of bales prepared by the machine on an ongoing, non-stop basis. An onboard computer preferably forming a part of the electronic system controls the process and assures its accuracy, while also providing information such as the average weight of bales weighed since last resetting the system.

摘要:
A viewing device synchronizer includes a viewing mechanism for viewing an object and a linking mechanism for linking a plurality of viewing mechanisms so that each is capable of viewing the object simultaneously. A movement mechanism moves a single viewing mechanism in any direction in order to view an object. A control mechanism moves any of the plurality of viewing mechanisms if the single viewing mechanism is moved. A directional pointing mechanism controls one or a plurality of the viewing mechanisms. A communication mechanism sends directional information for controlling the operation of the plurality of viewing mechanism from a single viewing mechanism.
