Abstract: A method of controlling formation of a bale includes: forming a bale from crop material by rotating the bale in a bale chamber; receiving with a controller of a control system at least one operating condition value corresponding to at least one operating condition sensed by a sensor when the bale is forming; automatically determining with the controller a power take-off speed of a drive mechanism responsive to receiving the at least one received operating condition value; and applying with the control system the determined power take-off speed to the drive mechanism.

Abstract: A method of controlling formation of a bale includes forming a bale from crop material by rotating the bale in a bale chamber and applying an amount of density pressure to the rotating bale. The method also includes receiving at least one operating condition value corresponding to at least one sensed operating condition when the bale is forming. The method further includes automatically determining the amount of bale density pressure applied to the bale responsive to receiving the at least one received operating condition value and controlling formation of the bale by causing the determined amount of bale density pressure to be applied to the bale.

Abstract: A twine brake device is so controlled that during an initial period in which the bale chamber is not filled with harvested material, the average tension in the twine, wire or cord is higher than during a second period in which the bale chamber is completely filled with harvested material.

Abstract: A screen for a skylight which is mounted on a substantially flat roof and which includes a frame having spaced apart vertical walls extending upwardly from the roof. The screen includes a plurality of longitudinal bars and a plurality of transverse bars secured thereto so as to form a plurality of rectangular openings. The transverse bars having a central portion forming an arch that is adapted to overlie the skylight. The transverse bars also include end portions having a substantially vertical section merging into the central portion and a substantially horizontal end section extending outwardly. The end sections are adapted to act as a foot allowing said screen to rest on and be supported by the roof. The transverse rods also include an intermediate section between the vertical section and the horizontal section that is spaced from the corner formed between the roof and each of the vertical walls of the skylight frame.

Abstract: A baler has a bale chamber and a needle movable through the bale chamber to pass a strand of twine from one side of the bale chamber to a knotter located on the opposite side, the twine being engaged by a tip of the needle. In the invention, pressurized air is directed at the needle tip. The supply of pressurized air may be discontinuous and timed to coincide only with certain phases of the needle operating cycle. The air stream avoids crop material being caught up in the knots formed by the knotter.

Abstract: In an example embodiment, a magnetic sensor has a magnet and a magneto-resistive, arranged on a substrate such that magnetic field lines through the magneto-resistive element are substantially parallel to a plane of the substrate. Movement of a movable magnetically permeable element MMPE near the substrate is detected as it alters the number of field lines through the element. The MMPE can be more sensitive than devices arranged with perpendicular field lines, and can be easier to manufacture and integrate. Applications include analog pointers, pressure sensors and microphones. The MMPE can use magnets placed either side of the element to detect changes in size of a gap above the element. As the gap closes, less of the parallel oriented field passes through the magneto resistive element.

Abstract: A round baler comprises a mechanism for encircling a bale after it has been formed with a wrapping material drawn from a web on a supply roll. A guide mechanism is provided for adjusting the width of the web of wrapping material as it is offered to a formed bale, so as to selectively enable and disable the wrapping of the edges of the bale.

Abstract: A round baler, having a pair of spaced side walls mounted on a main frame, is supported on wheels and adapted to be pulled across a field. A crop confining apron is mounted between the side walls for defining an expandable chamber that is adapted to rotatably form a cylindrical package of crop material between the side walls. A pickup picks up crop material and conveys it into the chamber through a generally transverse crop infeed opening operatively associated with the pickup. A transverse starter roll extends between the side walls to provide the upper limit of the infeed opening. A crop severing device extends into the expandable chamber in the vicinity of the starter roll to cut crop material on the surface of the cylindrical package as it is being formed.

Abstract: A filter holder for coffee cartridges, comprising a cartridge-receiving portion (4) with a closed bottom and a lateral extract passage (9), a by-pass (5) which has its inlet (6) spaced above the cartridge-receiving portion (4) and terminates adjacent the extract passage (9), as well as an upper supporting rim (7) which is so inclined relative to the axis of the closed bottom, that when the filter pan is arranged by the supporting rim (7) thereof on the upper edge of a receptacle for brewed coffee, the outlets of the by-pass (5) and the extract passage (9) are disposed substantially at the lowest point.

Abstract: A device for attaching a water jet device to a concentrate container or a reservoir by means of a clamping device or a foot, comprising a connecting piece, in which the foot is arranged to be fixed and put into sealing abutment with the insert piece in one movement, for which purpose the connecting piece is provided externally with threaded parts designed to cooperate through a bayonet catch with a complementarily designed part of the foot. The container, which is designed as a flexible bag, may be provided with a base plate at the position of the connecting piece, said connecting piece being designed as an insert piece, so as to ensure that the outlet opening of the insert piece remains open.

Abstract: A process and apparatus for monitoring and ensuring safe operation of unvented kerosene heaters in indoor spaces detects the hazard of incomplete combustion and the concomitant reduced O.sub.2 and increased CO.sub.2 levels in the indoor air. CO.sub.2 level in the indoor air is monitored quickly and accurately, - regardless of the burner's flame height. This is achieved by sensing O.sub.2 level in the burner exhaust which is used as a measure for monitoring the CO.sub.2 level in the indoor air and as a control signal. During burner operation outside a predetermined flame height range, the O.sub.2 detection is used both for restoring a normal heating condition and for monitoring operation at minimum flame height and to generate a warning signal and a delayed automatic shut-down of the burner.

Abstract: A method and an apparatus for making beverages, such as coffee, soup, tea, or the like, wherein a starting product, such as ground coffee, is supplied to a cavity and is enclosed therein by a piston. After this, through an opening provided in the piston, a quantity of fluid, in this case water, originating from a water system is pressed into said cavity. Hereafter, the fluid, after extraction of the starting product contained in the chamber, in this case filling chamber, is discharged through an opening near the end opposite the piston, the control of this process taking place electronically. The method is characterized in that use is made of an apparatus having at least two filling chambers of different size and mounted on a movable holder and that the various steps are performed during a single cycle of the holder.

Abstract: A method and an apparatus for withdrawing liquid from a reservoir, such as concentrate container, by means of a water jet device received in a clamping device. The reservoir is provided with an outlet opening having a valve mechanism fitted with a lip seal. The water jet device connects on the one hand to a water supply hose and on the other hand to a drain spout. The method and apparatus are characterized in that the reservoir is a flexible bag fitted with a connector or insert. The bag is received in a reservoir box whose underside has an opening for the passage of the connector or insert, as well as a plurality of passages for receiving the attachment elements of the clamping device.
