Title: Coupling device for connecting an implement to a working machine
Inventor: SONERUD AKE
IPC: E02F3/36
Filed: 1997-02-17
Granted: 2005-11-15
Abstract: The invention relates to a coupling arrangement for coupling a working implement to a working machine and being of the kind in which the two coupling parts are mutually connected both mechanically and hydraulically with no manual handling of the coupling arrangement. The machine-mounted coupling part includes drive means (10, 24) for moving associated hydraulic coupling connection means into coupling engagement with hydraulic coupling means (19) on the implement-mounted coupling part, when coupling the machine and implement. According to the invention, the hydraulic coupling connection (19) on the implement-mounted coupling part is movable in the direction of maneuvering movement of the hydraulic coupling, and is moved by the drive means (10, 24) via the hydraulic coupling connection (14) on the machine-mounted coupling part until coming into abutment with an abutment means (6) on the machine-mounted coupling part. The arrangement includes springs that function to exert a pressure that is opposed to this movement. The arrangement ensures that the clearance required for this mechanical coupling will not prevent effective and positive connection of the hydraulic couplings.

Title: Disposable test strips for determination of blood analytes, and methods and compositions for making same
Inventor: HALL GEOFF
IPC: G01N33/49
Filed: 1997-02-11
Granted: 2008-09-02
Abstract: An improved disposable glucose test strip for use in a test meter of the type which receives a disposable test strip and a sample of blood from a patient and performs an electrochemical analysis is made using a working formulation containing a filler, an enzyme effective to oxidize glucose, e.g., glucose oxidase, and a mediator effective to transfer electrons from the enzyme. The working formulation is printed over a conductive carbon base layer to form a working electrode. The filler, for example a silica filler, is selected to have a balance of hydrophobicity and hydrophilicity such that one drying it forms a two- dimensional network on the surface of the conductive base layer. The response of this test strip is essentially temperature independent over relevant temperature ranges and is substantially insensitive to the hematocrit of the patient.

Title: Method of compensating the dispersion of fluoride-based fibre lasers in the second optical window
Inventor: PEUPELMANN JENS
IPC: H01S3/098
Filed: 1997-09-13
Granted: 2004-11-16
Abstract: The invention concerns a method of manipulating a compensation fibre such that it can compensate the high negative dispersion of a fibre laser in the second optical window. According to the invention, the active fibre of the fibre laser is linked to a compensation fibre which consists of a step-index quartz glass core with a sheathing. By doping the compensation fibre sheathing with fluorine in a targeted manner, a positive value is set for the dispersion of the compensation fibre. Subsequent dimensioning of the length of the compensation fibre increases the set dispersion value to the positive dispersion value necessary for complete compensation of the dispersion of the fibre laser.

Granted: 2008-04-08
Abstract: Electrical switching apparatus such as a power circuit breaker, network protector or switch has a self-supporting operating mechanism module including a cage formed by a pair of side plates rigidly clamped in spaced relation by spacers. The cage supports all of the operating mechanism components including a helical compression close spring mounted fully between the side plates and coupled to a cam member through a rocker in a manner which maintains the forces longitudinal to the spring. The cam member has a charging cam with a charge profile for compressing the close spring and a close profile through which the spring drives the cam member to effect a controlled release of stored energy to close the contacts of the apparatus. A close prop, spring biased to an unlatched position, is latched to secure the close spring in the charged state by a latch assembly reset by a reset lever separate from the close prop which in turn is reset by rotation of the cam member during charging. An interlock prevents release of the close spring when the contacts are closed or the trip release is actuated. An indicator actuated by a driver pivoted against the cam shaft snaps from a DISCHARGED to a CHARGED indication as the close spring becomes fully charged and the driver drops into a notch created by a flat on the cam shaft. A snap action open/closed indicator for the switch contacts is also provided. Both indicators are pivotally mounted in a face plate pinned to the side plates and are connected to the operating mechanism by wireforms. The close and open push buttons snap out to a common shaft and have actuating fingers which trigger releases in the operating mechanism. The close rotating shafts are journaled solely in confronting apertures in the side plates. The cam shaft is captured between bushings seated in non-circular openings in the side plates thereby eliminating the need for any fasteners. Likewise, other parts mounted between the side plates and joined by pins having enlarged heads retained by the side plates do not need retainers. Various shafts extending between the side plates have reduced diameter ends of progressive lengths for successive insertion in one side plate to aid in assembly of the operating mechanism.

Granted: 2003-08-12
Abstract: The invention provides a system for recording and displaying a time sequential scene on a computer. The digital camera transmits a sequence of digital image frames to the timer representative of the image of a body passing a plane in space. Each frame represents a line object of the body, thus forming a fractional part of the scene. Once the frame reaches the image timer, it is digitally marked with a time reference and buffered into a block of information. The main control computer stores blocks of information from the image timer for a variety of processing and features available to the user. The invention also provides a selected memory, preferably a virtual memory subsystem, or hard-disc drive. Preferred constructions for adjusting camera pixel processing of light values, time-marking the images, creating colour palettes for interactive viewing of colour images, and video data coding to accommodate the high volume of line image data are described.

Abstract: A tea infusing device comprises a cup body, a filtering net, a buckling disk, and a water stopping device. The water stopping device is received in the center through hole of the cup body, and is formed by a metal rolling ball and a soft water stopping pad, or a water stopping block and a rod. A filtering net is installed thereon. A circular protruding ring portion with a proper height extends downwards from the bottom of the cup body. The buckling disk has a rod at the center thereof and is movable upwards and downwards. When the tea infusing device is arranged on a plane, the buckling disk will drop down naturally so that the water stopping device will close a through hole. Thus, the tea can be soaked in the cup. However, when the tea infusing device is located at any proper container. The buckling disk will be ejected by the container so as to eject the water stopping device so that tea water may flow to the container successfully. The improvement of the present invention is that the outer diameter of the buckling disk is smaller than the inner diameter of the protruding ring portion so that it can be completely received in the inner space thereof and longitudinally moves therein. Thus, water will not drain out due to an error contact to the buckling disk.

Granted: 2005-12-06
Abstract: A meat encasing machine has a looper horn (12), linking chain (24) and conveyor (14) which, prior to production, have home positions which are determined. A pulsed signal is generated as the looper horn (12) rotates and is transmitted to an amplifier (36) from an encoder (34) on the servo motor (32) for the looper horn (12) and the conveyor (14). The output pulse signal is then reduced in frequency so that it can be read by a PLC (40). The PLC (40) counts the pulses in the signal and can determine the relative position of the looper horn (12) based on the count and can therefore minimize the rotation of the looper horn (12) in the home position at the beginning of each new cycle. The meat encasing machine may also be controlled such that the linking chain (24), looper (12), and conveyor (14) have no direct mechanical or electrical interaction between each other. By driving the components with separate servo motors (26, 32), each can be precisely controlled in the desired ratios with respect to each other.

Title: Abs modulator solenoid with a pressure balancing piston
Inventor: HO THANH
IPC: B60T15/02
Filed: 1998-08-21
Granted: 2008-04-15
Abstract: An ABS modulator solenoid valve (10), having one electric so-lenoid (12), in which the valve con-trol piston (14) has a passage (16) therethrough for balancing the pneu-matic pressure on both ends (34, 36) of the control piston (14). One end (34) of the piston (14) is disposed in a closed piston chamber (32) while the other end (36) is positioned to contact and position a valve spool (40). The passage (16) extends between the ends (34, 36) of the piston (14). Piston (14) is biased by a spring (50) to a position within the piston chamber (32). When the so-lenoid (12) is de-energized, the pis-ton (14) remains in this position and variable air pressure, from an opera-tor controlled brake valve (126), can be supplied through the valve (10) to a brake chamber (128) for operat-ing the vehicle service brakes. Dur-ing an ABS application, the solenoid (12) is energized to overcome the in-let spring (50) bias and the piston (14) moves into engagement with the valve spool (40). The spool (40) is biased by an exhaust spring (52) to a position wherein the exhaust port (24) is isolated from the supply port (20) and the delivery port (22). When the solenoid (12) is fully energized, the piston (14) engages the spool (40) and moves it to the exhaust position. When the solenoid is energizedwith a selected hold current, the piston (14) engages but does not move the spool (40) and t he valve (10) is then in a hold position. Since the pressure on the ends-(34, 36) of the piston (14) is balanced, the force required to move the piston (14) to the hold position is relatively constant and not greatly effected by the pneumatic pressure at the supply port (20) or th e delivery port (22).

Abstract: A method and system for transferring information using an encryption mode indicator (EMI).      The present invention provides several secure information communication modes in which data (e.g., representing an audio/visual work) can be transmitted from a source device to a sink device (receiving station) in a number of secure modes. In one secure mode, EMI mode A, the information of the transmission is not allowed to be copied as a whole work; this is the highest level of copy protection. In second secure mode, EMI mode B, the information of the transmission is allowed to be copied once and once only by the sink device.      In a third transmission mode, no encryption is used and free copying is availabe. Depending on which secure mode is selected between mode A and made B, a different encryption process is used by the source device to encrypt the transmission. Further, depending on which secure mode is selected between mode A and mode B, a different decryption process is used by the sink device to decrypt the transmission. The present invention is particularly useful for transmissions between a source device and a bit stream recorder which does not have the capability to extract certain encryption information from a packet header. By using different encryption processes for each transmission mode, an unauthorized device placed between the source and the sink devices that alters the EMI code will be unable to thereafter render or record the audiovisual work because the decryption process selected will differ from the encryption process used.

Abstract: The present invention provides a method and apparatus for securing cryptographic devices against attacks involving external monitoring and analysis. A "self-healing" property is introduced, enabling security to be continually re-established following partial compromises.   In addition to producing useful cryptographic results, a typical leak-resistant cryptographic operation modifies or updates (330) secret key material in a manner designed to render useless any information about the secrets that may have previously leaked from the system. Exemplary leak-proof and leak-resistant implementations of the invention are shown for symmetric authentication (350), certified Diffie-Hellman (when either one or both users have certificates), RSA, ElGamal public key decryption (303).
