Abstract: A fastener for installing barbed wire having a helical shaped eye portion that is attached to a threaded shank. The eye portion having gaps and clearances that allow for barbed wire to be locked to a fence post and properly tightened. Additionally, a driving mechanism that has a specially designed slotted cavity that receives the eye portion of the barbed wire fastener for easy installation of the barbed wire to a fence post.

Abstract: An extended male slipper servo pad provides an improved connection between the swashplate and a positioning mechanism in a variable displacement hydraulic unit. The swashplate assembly includes a swashplate having a socket formed therein and a male slipper servo pad pivotally attached to the swashplate at the socket. The male slipper servo pad has a ball end secured in the socket and a pad end having a substantially flat planar surface thereon directed away from the ball end.

Abstract: A pump housing assembly includes a housing, a hub portion, and a flange. The housing has an end cowling defining a transition from a central portion of the housing to a transverse end portion. The hub portion extends longitudinally outwardly from the transverse end portion of housing. The flange extends radially outwardly from the outward end of the hub and is in spaced longitudinal relation to the end of the cowling to create a space to receive a head of a mounting bolt. The flange has an outer periphery with a pair of tangentially extending slots having an open end. The space for receiving a head of a mounting bolt is less than the length of a shank of a mounting bolt, to minimize the length of the housing. The slots have a width sufficient to receive the movement of a shank into and out of the open ends of the slots.

Abstract: A lathe cut sealing ring includes a substantially cylindrical ring of elastomeric material formed about a central axis. The ring includes a rectangular cross-section and has an inner diameter, an outer diameter, opposite planar upper and lower surfaces, and a plurality of angularly spaced positioning ribs protruding inwardly from the inner diameter. This sealing ring and the groove in which it is located can advantageously be formed with simple and cost-effective lathe cutting operations.
