Title: Chaff cutter for comminuting haulm behind the grain-separator devices of a combine harvester
Inventor: JAKOBI WILHELM
IPC: A01F12/40
Filed: 1996-09-10
Abstract: The subject matter of the invention is a straw-cutting machine which is disposed behind the grain separating devices of a combine harvester and whose separating means cut up the stalks falling down from the straw walkers into short pieces.  In this process, thanks to an innovative, special disposition of the generally conventional deflector which, under the straw walkers, deflects the stalks falling down from these to the cutter tray at the inlet into the cutter, the receiving of the stalks by the cutting drum is made more secure and, on the other hand, thanks to an innovative, special design of the distribution hood following the cutter, the ejection and the distribution of the chopped up stalks over the field soil is essentially improved over existing designs.

Abstract: Inventive two-dimensional barcodes, each having encoded digital information in a bitmap representing preferably randomized encoded data bits, are printed onto a printed medium. Preferably, error correction codes are added to the digital information to ensure that the decoding process accurately reproduce the digital information. In one embodiment, the bitmap may further include "anchor" bits in each corner, which are used as part of the skew estimation and deskewing processes during decoding. In a second embodiment, no "anchor" bits are required. The encoded digital information is mapped into the two-dimensional barcode in such a way as to minimize the errors caused by damage to particular rows and/or columns, for example, row damage caused by faxing the printed barcode. To extract the encoded digital information from the printed medium, the printed medium is scanned, then the bitmap is located within the printed medium. The skew of the bitmap, if any, is determined, and the bitmap is deskewed if necessary. The bitmap is then cropped, and the randomized digital information is read from the bitmap. The digital information is derandomized and any error correction codes are removed, in the process correcting and/or recording any errors discovered, thereby reproducing the original encoded digital information.

Title: Safety mechanism for a firing pin
Inventor: FLUHR NORBERT
IPC: F41A17/64
Filed: 1998-01-23
Abstract: The present invention relates to a safety mechanism for the firing pin (5) of an anvil trigger system (5), said firing pin (5) being fitted with a spring (9) which, when in a position of rest, presses against a rear stop (13) while keeping at a distance of the cartridge primer which is located prior thereto and designed with a back taper (11) close to its back end. The safety device includes a spring-fitted mechanism (29, 31, 33) which, when in a position of rest, engages with a hammer spur (29) into the back taper, thereby maintaining the firing pin (7) in a position of rest.        This locking part enters the travelling path of the anvil (5) in such a way that the latter (5), by meeting with the back end of the firing pin (7), first meets with the chamfer (35), pushes it aside against the spring effect, thereby releasing the cartridge (3). The safety mechanism (21, 31, 33) is designed as a single-level leaf spring (21) and presents a spring leg (23) extending from the hammer spur (29) forwards and taking its bearing before the firing pin back end. The spring leg extends to the area of the firing pin (27) front end, designed as an extraction tooth.

Abstract: A versatile apparatus (2) for controlling the transmission of rotational forces between first and second rotatable members preferably takes the form of a clutch that can be activated by axially shifting an internal actuation member (140) through the introduction of either liquid or gaseous mediums. The clutch includes first and second transmission members (177, 281) which are rotatably mounted within a housing (5) and adapted to be attached to the first and second rotatable members respectively. A coupling assembly (226), preferably including first and second sets of axially spaced interface elements (252-254 and 274, 275), is interposed between the transmission members (177, 284) within the housing and axial movement of the actuation member (140) causes the interface elements (252-254 and 274, 275) to be frictionally engaged. In the preferred embodiment, the first and second sets of axially spaced friction interface elements (252-254 and 274, 275) are biased to a disengaged position by back-to-back arranged belleville washers (264-268), which maintain a constant disengagement force regardless of wear on the frictional surfaces thereof. To minimize associated manufacturing costs, the housing (5) is cast from aluminum. To assure that the clutch can work effectively with various fluid mediums, internal surfaces (19, 58) of the housing (5), against which seals (155, 170) of the actuation member (140) slideably abut, are coated with a hard coat anodize having a TEFLONTM and epoxy filler.

Title: Communication methods and apparatus
Inventor: MUDGE DAVID DENIS
IPC: H04B7/185
Filed: 1999-11-15
Abstract: In a bandwidth allocation protocol for a mobile communications network, mobile terminals report their bandwidth requirements to the network, while the network controls the amount of bandwidth that is used by the mobiles in reporting their bandwidth requirements. The mobiles indicate the total quantity of data awaiting transmission, the maximum delay time of the most urgent portion of the data and the maximum delay time of the least urgent portion. If a collision occurs between transmission by two mobiles, the mobiles wait for an interval controlled by the network before attempting another contention-based access transmission. The network periodically varies the contention-based access capacity available according to the observed usage level and/or collision rate in the previously allocated contention-based access capacity. The network analyses the forward traffic to individual mobiles and predicts the return bandwidth requirements which are likely to result from the forward traffic. The network stores associations between forward and return frequency channels, so that when a mobile receiving a forward frequency channel request return capacity, the network preferentially assigns return bandwidth to the mobile in one or more of the associated return channels.

Title: Laser system providing power ramp-up and method of operating same
Inventor: HERITIER JEAN-MARC
IPC: H01S3/102
Filed: 2000-04-03
Abstract: In a laser system which produces radiation which is highly absorbed by water, the pump voltage supplied to the laser rod is slowly increased between the lasing threshold voltage and the full operational voltage of the pump. As a result, the output energy and circulating energy of the system slowly increase, such that any water on the intracavity coatings is vaporized slowly, rather than explosively. The laser system and method of using same thus reduce or prevent damage to the intracavity coatings used within the laser cavity.
