Inventor: TRIBBETT KEVIN NEIL
IPC: F16H25/24
Filed: 1997-01-29
Abstract: The actuator includes a housing (12) and a gear nut (64) within the housing (12). A leadscrew (78) on which the gear nut (64) is threaded traverses the housing (12). As the leadscrew (78) moves axially, the gear nut (64) rotates.  To prevent misalignment between the gear nut (64) and leadscrew (78), the gear nut's outer walls (74 and 76) and bearing surfaces (30 and 46) within the housing (12) permit the gear nut's axis of rotation to pivot in any direction along with any pivoting of the leadscrew (78), while allowing the gear nut (64) to rotate about the leadscrew (78). Therefore, if the leadscrew (78) is not aligned with the housing (12), the leadscrew will pivot the gear nut (64) so that the gear nut (64) remains aligned with the leadscrew (78) and movement of the leadscrew (78) can continue.

Abstract: The invention relates to 2 device for settin~ .he length of a top link of an attaching aevice of a trac~or, with there being provided a piston/cylinder unit 14 for length setting purposes. The piston/cylinder unit 14 is pro~ided with  a  displacement  sensor  20  which  records  the respective actual length setting of the top link 7 and generates a a~tual length signal which is pro?ortional thereto.  Furthermore,  there is provided a lift position sen~or 13 which generates an electric signa~ representing the re~pective actual lift position of the lower steering arms 4. A no~inal length setting of the top link 7, which re~ers to the respective actual  lift position,  can be stored in the stoxage unit 33. When a new actual lift position  is  reached  ~u~ing  the  automatic mode of operation,    it  is  possible  to  generate  an  electric control signal which corresponds to the nominel length setting of the top link and which is transmitted to the comparator of a control unit 34. Said comparator compares the  control  signal  with the  actual  length  si~nal  and controls the piston/cylindex unit 14 as a ~unctio~ of the deviation o~ the  signals  from one  another,  towards  a nominal  length  settin~.  In  this  way  it  is  possible, auto~atically,  to  achie~e  optimum  kinematics  for  an implement attached to the tractor,  without any outside interference.

Abstract: A dispenser for rolled sheet media comprises a frame, for mounting to a surface, hawing a front side for dispensing the rolled sheet media and an opposite back side.  The frame defines facing slots on each end thereof, the slots spaced apart to accommodate the length of the roll between them and the slots oriented at an angle to the vertical. A roll pin is inserted into the roll of sheet media, and then is slidably engaged in the slots. Free rotation of the roll is retarded by a retarding member on which the roll rests when the roll and pin are installed. The roll rotates substantially freely when the sheet media is pulled from the roll in a horizontal direction and retardation of rotation increases when the sheet media is pulled from the roll in a downwards direction, the degree of retardation increasing as the degree of pull below the horizontal direction increases. A downward vertical pull causes the retardation of the roll to increase to the point where a perforated sheet media may be torn off, allowing one-handed operation. A cutting member, may be provided for un-perforated sheet media.

Filed: 1997-12-18
Abstract: A computer system executable method is provided for managing resources in an automated workflow system for manipulating a work item, the work item being stored in a database of work items for subsequent execution by an operator and meeting a predetermined criteria. A first definitional data item is stored in a memory, the first definitional data item affecting how the workflow system processes work items meeting the predetermined criteria. A directive is received from an administrator to remove the first definitional data item from the memory. A mark is set, the mark being associated with the first definitional data item to indicate that the first definitional data item is to be removed from the memory. If a second definitional data item is normally able to be made dependent on the first definitional data item, the mark is used to prevent the second definitional data item from being made dependent on the first definitional data item after the mark was set. The mark is used to prevent the first definitional data item from affecting another work item if the other work item failed to meet the predetermined criteria until after the mark was set. The work item is processed until the work item no longer meets the predetermined criteria. It is determined whether any other definitional data items are dependent on the first definitional data item. Depending on the outcome of the determination, the first definitional data item is removed from the memory.

Inventor: RYAN JIMMY DON
IPC: E21B21/10
Filed: 1998-10-27
Abstract: A downhole cutting separator is disclosed. The separator can be mounted anywhere on the drillstring. The separator employs a seal (35) which directs the normally circulating fluid during the cutting or milling operation in through an internal passage (60) in the tool. The cutting-laden fluid passes through a slotted liner (16) where the cuttings drop out and are collected in a compartment (24) within the tool. The circulating fluid exits the tool into the annulus. The tools can be used in series so that the lowermost tool takes out the large cuttings, while an upper tool takes out the finer cuttings. Provisions can be made to bypass the tool should it become plugged with cuttings by using rupture discs or movable sleeves responsive to pressure differential. A portion of the body assembly (30) can be magnetic to further assist in removal of cuttings as the circulating flow passes through the tool.
