Abstract: The present invention provides a transdermal spray drug delivery system which comprises: a therapeutically effective amount of a hormone; at least one dermal penetration enhancer; and at least one volatile liquid. The invention also provides a method for administering at least one systemic acting hormone which comprises applying an effective amount of the hormone in the form of the drug delivery system of the present invention.

Abstract: A vehicle includes front and rear sections which are pivotally connected to enable the rear section to articulate relative to the front section. A drive train connects a transmission on the front vehicle section to a differential on the rear vehicle section and transmits power between the transmission and the differential while allowing the rear section to articulate relative to the front section. The drive train includes a shaft of fixed length extending from the transmission to a universal joint and includes a shaft of variable length extending from the universal joint to the differential.

Abstract: The yoke of a driveline is formed with diametrically spaced and generally semi-cylindrical pockets for receiving the bearing caps of the cross of a universal joint. A notch is formed in each pocket and receives the shank of a pin whose head projects into overlying relation with the pocket and into engagement with the bearing cap to captivate the bearing cap axially in the pocket. The inner end portion of the yoke is formed on a spherical radius and is adapted to pilot into drive tubes of varying internal diameters.

Abstract: An interlocking seal assembly for a universal joint which acts both to seal the bearing assembly as well as to retain the bearing block from falling off the spider in the joint. This assembly includes a resilient sealing member engaging a trunnion and having a backing ring housing the seal and adapted to be press fitted into the bearing block on the trunnion and a loose fitting generally cylindrical shield adapted to be press fitted onto a diameter of the spider. The backing ring and shield have overlapping lips providing the interlock to retain the bearing block on the spider.

Abstract: A pressure switch including a housing 10, electrical contacts 16, 24 within the housing and a lever 26 movably mounted within the housing and operable to effect relative movement between the contacts. A biasing spring 70 biases the lever in a first direction and is settable through elements 74, 76, 78, 80 to determine the pressure level at which the switch will operate. An over center device 36, 38, 40, 42, 44, 46, 50, 52, 54, 56, 58 is located within the housing and is connected to the lever to provide snap action movement of the contact. A pressure port 96 is located in the housing and a fluid motor including a rolling diaphragm 116 is in fluid communication with the pressure port and acts in opposition to the biasing spring 70.

Abstract: A sectional liner for use on the interior of a ball mill liner or rotary pulverizer. The sectional liner has a rubber base that is undulating or sinuate in contour. Means are provided in the rubber base to facilitate the securing of the base to the shell of a ball mill. The rubber base may or may not be covered with a layer of fiberglass which in turn is covered with an exterior surface of polyurethane. Ceramic tiles are embedded in the polyurethane being aligned in rows with a clearance space between the tiles filled with polurethane. The ceramic tiles, polyurethane, and rubber are all bonded together during the cure cycle to form a one piece replaceable sectional liner for ball mills.

Abstract: Pharmaceutical compositions for treating potassium deficiency in monogastric animals comprising gelatin capsules containing mixture comprised of controlled release form of microencapsulated potassium salt and hydrophilic surfactant are disclosed.

Abstract: A liner member for rotary drum-type mills comprises a resilient portion of wear, abrasion and impact resistant elastomeric material with a rigid plastic portion bonded to each side thereof. The liner member is specially adapted for mills which employ spaced lifter bars along selected interior surface portions of the mill with the liner member fitted between the lifter bars such that the resilient portion of the liner is disposed to protect the walls of the mill from wear, abrasion and impact while the liner is held in position by the lifter bars which bear against the two rigid portions bonded to the sides of the resilient portion.
