摘要:
In a swather formed by a tractor and attached heeder for cutting standing crop to form a swath, reel speed and optionally draper speed are controlled relative to ground speed by a control system including a manually operable input and display available to the operator. The control system acts to calibrate” the control output so that the control module has a secondary reference point as to how the PWM valve should function in the event of a speed sensor failure. Instead of using the speed sensor signal as a reference, the control system now compares the set point with the stored table (which may in one example provide 256 values) containing the PWM voltage/current values. These values correspond to a set of actual speed sensor values taken during the profiling procedure, plus extrapolated values equalling 256 points.

A tractor has hydraulically driven wheels at a cab end and castor wheels at an engine end. It can be driven cab forward in a working mode with a header on the forward end. It is rotated to engine forward in the transport position for more stable higher speed travel. The driver's console is rotated in the cab with the steering and speed control elements moved with the seat for the driver to face forwards and its position is detected by switches. In the engine forward position for transportation, the control system detects the seat position and operates the controls for higher speed drive and to prevent operation of the header. A vehicle emblem SMV is located on the back of the driver's seat so that it is visible to a person behind regardless of the direction of travel.

In a swather formed by a tractor and attached heeder for cutting standing crop to form a swath, reel speed and optionally draper speed are controlled relative to ground speed by a control system including a manually operable input and display available to the operator. The control system can be used in an automatic mode to set an index value for an actual difference in reel speed relative to ground speed and to vary reel speed accordingly. In this mode a manually operable control varies the index. The control system can be switched by the operator to manual in which case the same control varies the actual reel speed. Minimum reel speed can be set by the same control and when operative the automatic system does not allow reel speed to fall below the minimum set value despite the values of index and ground speed. A crop-lodged switch is also provided which when operated acts to move the header to a lowered position and the move the reel to a forward most and lowermost position in a single operation controlled by the single switch.

A system for collecting and disposing of liquid medical waste includes a fluid collection cart and a draining and cleaning station. The fluid collection cart includes a pair of containers, each of which includes a draining port and a cap. Each cap includes an outer portion having a flushing port and a bore formed therein and an inner portion having vacuum and patient ports formed therein. The inner cap portion is disposable and removably positioned within the bore of the outer cap portion. Liquid level detectors also communicate with each container. The cart also includes a regulator so a low vacuum level may be pulled on one of the containers while a full vacuum level is pulled on the other container. Fluids are collected in the containers via suction tubes connected to the patient ports. The flushing and drain ports of the containers are connected to corresponding flushing and drain connectors on the station when the containers are full so that they may be drained and flushed. The cart liquid level detectors communicate with the station microprocessor so that the draining and flushing cycles may be properly sequenced. The station may also clean suction canisters.

Methods and compositions for improved ruminant diets are disclosed. The invention relates to the use of metal ion/metal ion salts in ruminant feed, at levels from about 0.25 to about 1 g/kg dry matter, in any ruminant diet, for improvement of bypass protein content, as well as to influence the rate of rumen starch digestion and the flow of starch to the duodenum.

The present invention relates to a pocket knife having a rotation type can opener for opening a can. The rotation type can opener has a crank, a shaft, a gear and a cutting blade; the upper rim of the can is put to be infixed between the cutting blade and the gear, with the top end of the can holding the cutting blade; the crank is rotated to drive the rotation of the shaft, the rotated shaft further drives the rotation of the gear, and the rotated gear engages the upper rim of the can and drives the rotation of the can; the top end of the rotated can produces a pressure against the cutting blade so that the cutting blade first penetrates and then rotationally cuts apart the top end of the can.
摘要:
The present invention is based on the discovery that moist heat treated ruminant animal feed compositions comprising a fermentation biomass, have increased amounts of proteinaceous matter that escapes fermentation within the rumen. The ruminant animal feed compositions may further comprise, alone or in combination, one or more of an isolated enzyme, an organic acid, a gluten protein, at least one divalent metal ion and at least one plant extract. The proteinaceous matter may then be digested or metabolized in the post-rumen portions of the ruminant digestive system, thereby providing further increased energy and protein levels for ruminant animals during times of increased productivity. Compositions and methods of manufacture of the compositions of the embodiments of the present disclosure are disclosed.
摘要:
A bipolar transistor with raised extrinsic base and selectable self-alignment between the extrinsic base and the emitter is disclosed. The fabrication method may include the formation of a predefined thickness of a first extrinsic base layer of polysilicon or silicon on an intrinsic base. A dielectric landing pad is then formed by lithography on the first extrinsic base layer. Next, a second extrinsic base layer of polysilicon or silicon is formed on top of the dielectric landing pad to finalize the raised extrinsic base total thickness. An emitter opening is formed using lithography and RIE, where the second extrinsic base layer is etched stopping on the dielectric landing pad. The degree of self-alignment between the emitter and the raised extrinsic base is achieved by selecting the first extrinsic base layer thickness, the dielectric landing pad width, and the spacer width.

The invention relates to a device for managing battery packs by measuring and monitoring the operating capacity of individual battery modules in a battery pack. A programmable logic controller directs the selective closing of relays to allow individual battery modules to be load-tested using a variable discharge load unit, without compromising useful battery pack capacity. A battery module whose useful capacity falls below a predefined threshold may be connected to a battery charger for replenishment and then electrically realigned with the remaining modules in the pack for continued operation. Alternatively, an alarm may be triggered which alerts the user that the module is due for replacement. This sequence of events is performed on all cells in the pack at a predetermined interval.
