Abstract: A novel solution for changing sweeps or knives on a cultivator or other soil working tool is the subject matter of the present invention. In today's farming world, where labor is at a premium and time is of the essence, a sole operator or farmer in preparing the fields for planting, summer fallow or other operations will sometimes need to change the sweeps or knives which till the ground several times for different crops or operations. The novel invention herein provides for an apparatus for quickly removing the sweeps on cultivator shanks and replacing them with other soil openers of different width or configuration. A simple press button releases the sweep from an adapter bolted to a standard cultivator shank. The present invention eliminates the problem of sweeps falling off shanks due to lack of friction or difficulty in removing sweeps because of over friction.

Title: Diagnosing malfunctions in materials handling vehicles
Inventor: GASKELL JAMES W
IPC: B66F9/24
Filed: 1998-09-28
Granted: 2006-04-04
Abstract: A diagnosis system for materials handling vehicles leads service personnel step-by-step through diagnosis and repair of malfunctions within the vehicle. Malfunctions are assigned corresponding event codes so that when a malfunction is detected, its corresponding event code is displayed. The event codes uniquely identify systems of the vehicle in which malfunctions have occurred by having the event codes for a given vehicle system all start with the same number. Thus, the technician knows from the event code what system needs to be diagnosed/repaired and what tools and probable parts will be needed. The eve nt code is used to access diagnosis information identifying the portion of the vehicle wherein the malfunction has occurred, the components which caused the malfunction and, preferably, provides a pictogram of that portion of the vehicle. The technician advances to the malfunctioning portion of the vehicle where another pictorial depiction of the components of that portion of the vehicle assists in locati ng the components.

Abstract: In the method for treating the surface of the web, liquid is added on the surface of a paper or paperboard web (W), possibly with other constituents. The absorbency of the surface of the paper or paperboard web is increased before liquid is brought on the surface of the web or simultaneously with bringing the liquid on the surface of the web. The method is used for wetting the surface of the web before calendering, or for coating the web in surface sizing or pigmenting. The absorbency of the surface is increased before bringing the liquid for example by means of a corona treatment, a flame treatment, an ozonization or by adding steam.

Abstract: A coil tubing injector assembly includes a frame structure and a pair of gripper chain drive systems mounted to the frame structure. The pair of gripper chain drive systems are disposed in a common plane and spaced apart from each other, and adapted to engage a first and a second coil tubing string to inject both of the first and second coil tubing strings into, and withdraw both the first and second strings from, a subterranean well. The first and second coil tubing strings may be injected synchronously or asynchronously depending on the structure of the injector. The coil tubing injector assembly reduces the time required to perform many downhole operations, and therefore reduces well completion, stimulation and re-completion expenses.

Abstract: A method and assembly (kit) are provided for use by propane tank service personnel to detect escaping gas in propane tank systems. In one embodiment, the standard connection between the regulator and tank service valve is replaced with a permanent valve arrangement including a main connection between the regulator and valve and a valve unit disposed in a branch connection of the valve assembly. In a second embodiment, a permanent valve assembly is screwed into a pressure port in the tank regulator system. A separate pressure gauge is individually assigned to tank service personnel and adapted to be carried by such personnel in testing the pressure in the propane tank. The pressure gauge is affixed, e.g., through a hose, to a valve unit connector including an actuator, e.g., a valve stem operator, for actuating the valve unit. When the pressure gauge is connected to the valve unit, the latter is actuated to provide an immediate reading of the tank pressure (depending, in the second embodiment, on the location of the pressure port). A determination is made from this reading whether the tank is out of gas, and if the tank is out of gas, the service valve is turned on, gas introduced, the service valve turned off and a further pressure check made to determine whether gas is leaking. In the second embodiment, the valve unit includes a valve housing with a restricted (0.054 inch or smaller) inlet.

Abstract: A method and automatic test system for determining qualification of a twisted pair transmission line to propagate data signals. The method includes measuring phase imbalance in the twisted pair transmission line. The phase imbalance is determined by resistance imbalance in the twisted pair transmission line. The resistance imbalance is determined by applying a common mode voltage to the twisted pair transmission line; and determining phase imbalance in the twisted pair in response to the applied common mode voltage. The method includes applying a common mode voltage to the twisted pair transmission line; determining phase imbalance in the twisted pair in response to the applied common mode voltage; detecting a peak in the determined phase imbalance; determining a frequency of the detected peak; determining line qualification in accordance with the determined frequency. Methods are provided using series resistive imbalance and phase measurements to discover the type of imbalance existing on a twisted pair transmission line which is unable to support data transmissions. Methods are provided using series resistive imbalance and phase measurements to determine where an imbalance occurs as well as the magnitude of the imbalance.

Abstract: Procédés et dispositifs servant à stériliser de petits objets. On introduit un petit objet dans une chambre située dans le stérilisateur. Une partie de ce petit objet épouse un mécanisme de verrouillage, ce qui met ce dernier hors service. Après la mise hors service du mécanisme de verrouillage, le stérilisateur produit au moins un éclair de lumière ultraviolette extrêmement intense émise par une source de lumière ultraviolette. Cet éclair de lumière ultraviolette détruit les micro-organismes de la surface du petit objet. La chambre du stérilisateur peut être doublée par un revêtement réfléchissant afin de disperser la lumière ultraviolette autour de la chambre, de sorte que la majeure partie, sinon la totalité, du petit objet placé à l'intérieur du stérilisateur est exposée à la lumière ultraviolette.

Abstract: The separation process is for separating a target component from a liquid incorporating the target component with other components. It comprises the steps of providing a bed of particulate packing medium; flowing liquid upwardly through the bed of particulate packing medium; through a restricted-permeability element and through a process outlet, to expand the bed in the bed space and effect separation of the target component from the liquid through retention by the particulate packing medium; opening a clearing outlet communicating directly with the bed space, at or adjacent the restricted-permeability element; and forcing a clearing flow of fluid relative to the restricted permeability element to disturb the particulate matter which has accumulated against it, and causing said matter to pass out of the bed space through the clearing outlet.

Abstract: A system and method for controlling an eye movement tracker includes monitoring a plurality of eye positions by following a feature using the tracker. An optical beam is sent into the eye, and an intensity of a reflected beam from the eye is sensed at each position. If the intensity of the reflected beam fluctuates from a predetermined acceptable intensity range, the tracker is returned to a frozen position. The frozen position comprises a most recent position at which the intensity lay within the intensity range. The tracker is also frozen if the noise in the signal exceeds a predetermined acceptable maximum noise level and for counting a number of times the tracker is frozen. The procedure is aborted if the tracker is frozen repeatedly and for a time exceeding a predetermined maximum acceptable time.
