Abstract: VEHICLE BRAKE SYSTEM WITH TRANSMISSION AND INTERNAL BRAKE                 Abstract of the Disclosure A vehicle brake system having service brakes and a transmission with internal brakes in the transmission includ-ing an output brake and a gear reaction brake system providing friction braking of the transmission output.  The transmission has planetary gearing in a housing and a first ratio fluid-operated reaction brake for braking a reaction gear for first ratio drive, and second and third ratio fluid-operated friction devices for establishing second and third ratio drives.  The service brake system engages the service brakes and provides an output brake pressure increasing with brake demand to engage the output brake to brake the output shaft in all ratio drives.  The first ratio reaction brake and the output brake have a common movable backing plate, so engagement of the output brakes moves the common backing plate in second and third ratio drives to engage the first ratio reaction brake in addition to the engaged second or third ratio drive friction device to provide increasing total internal braking, including friction braking by the output brake and by the gear reaction brake system, increasing with brake demand.  At constant brake demand, the total internal output brake power increases with speed in a constant proportion in one arrangement, and in steps at each upshift in another arrangement.

Abstract: INK DROP COMPENSATION BASED ON                    PRINT-DATA BLOCKS                           Abstract The invention relates to an ink jet printer and in particular to correcting the flight path of drops from the printer to reduce print position error on the print media.  It has been found that drops as far as 30 drop positions ahead of a drop in the ink stream can have an effect on the flight path of that drop to the print media.  Using a memory to store 230 compensation values to correct the flight of the drop for all possible combinations of drop patterns in the ink stream is not practical.  Disclosed herein is a method and apparatus for using a smaller number of compensation values to correct the flight path for all possible combinations. This is accomplished by grouping the drops remote in position from the drop being compensated into blocks of drops and treating the entire block of drops as contributing one effect on the flight of the drop. Accordingly, drops close to the compensated drop are treated as having an individual effect on the flight path while drops remote from the compensated drop are grouped into one of more blocks and each block is treated as having a single effect on the compensated drop.

Abstract: LABEL ROLL AND METHOD OF MAKING SAME          Abstract of the Disclosure There is disclosed a composite web of labels in a supply roll, method of making a label roll and method of dispensing labels.  The composite web has a web of supporting material and labels releasably adhered to the supporting material web.  There are groups of slits in the supporting material web and in the labels at longitudinally spaced apart locations.  The slits are shown to be in a generally Y-shaped configuration.  Each group has a generally longitudinally extending slit and two slits disposed at an angle with respect to the transverse direction across the web.  The two slits extend at an angle to the transverse direction from a generally V-shaped flap or flap portion.  The slits are shown to be spaced apart by a land or frangible portion.  The labels are dispensed from the roll by drawing the web about a delaminator in a direction that the flap portions trail across the delaminator.          A toothed driver engages the web downstream of the delaminator and enters the longitudinal slit at a position upstream of the flap portion, severs the frangible portion and folds the flap portion out of the plane of the web.

Abstract: "SMOOTHING TINE ASSEMBLIES FOR CULTIVATORS" ABSTRACT OF THE DISCLOSURE           A plurality of resilient ground smoothing tines are pivotally secured behind a cultivator and are raised and lowered with cultivator shovels.  As the smoothing tine assembly is raised with the cultivator shovels, the top links between the smoothing tine frame and the cultivator frame are forced to jack-knife thus causing the smoothing tines to be lifted clear of the ground for clearance pur-poses and to dump any straw or trash which might be engag-ed thereby.  The tines  are shaped and are resilient so that they vibrate as they pass over the rough ground left by the cultivator shovels, not only smoothing and breaking up the rough soil, but vibrating vertically which assists in dumping straw which may have been picked up by the tine ends.  The tines also incline downwardly and rearwardly which also facilitates straw dumping and prevents the straw from bunching up and climbing the tines.

Abstract: TIME DIVISION SWITCHING SYSTEM CONTROL ARRANGEMENT          Abstract A time division switching system having distributed control processors is disclosed.  The distributed processors exchange control messages and cooperate in the completion of talking paths between subscribers.  Each control message includes an address portion defining the destination for the control message and is transmitted to a time-shared space division switch on the same time multiplex lines that speech representations are transmitted.  Control messages are routed by the time-shared space division switch to a control distribution unit where the address portion is interpreted.  When the address portion defines a distributed processor which controls the time-shared space division switch, the control distribution unit transmits the associated control message directly to that processor. Alternatively, when the address portion defines one of the other distributed processors, the control distribution unit transmits the associated control message to the defined processor via the time-shared space division switch.  The switching system also includes arrangements for utilizing the control message communication features in the completion of communication paths between subscribers.

Abstract: ABSTRACT OF THE DISCLOSURE A tractor locking differential (12, 18) is controlled by a solenoid operated hydraulic valve (34).  The solenoid valve is in turn controlled by a logic circuit (36) which is responsive to signals received from a differential lock floor switch (32), application of brake lights (26) through the closing of a contact (28 or 30), and also from powering up the tractor.  When the ignition (20) is turned on a flip-flop (50) within the circuit (36) will be cleared by action of a power up to clear circuit  (58, 60, 64, 66) to dispose valve (34) in its unlocked position. After power up the operator can selectively lock or unlock the differential by application of momentary contact switch (32) which causes flip-flop (50) to toggle.  When a brake light switch (28 or 30) is closed the flip-flop (50) will be cleared causing valve (34) to be disposed in its unlocked position.     Docket 5450
