Title: Novel method of progesterone delivery and affect thereof
Inventor: BOLOGNA WILLIAM J
IPC: A61K9/00
Filed: 1994-09-14
Abstract: The present invention teaches that relatively low levels of serum progesterone, 1 to 6 ng/ml, may be used to prevent endometrial cancer. The vaginal delivery of progesterone using a cross-linked polycarboxylic polymer produces this low serum progesterone level while also providing the full secretory transformation of the endometrium, indicating the efficacy of the progesterone. Such low levels of serum progesterone will decrease the risk of breast cancer experienced by women undergoing hormone replacement therapy ("HRT") and minimize the potential of other undesirable progesterone associated side effects.

Abstract: A vending machine for dispensing cups comprising a rotatable turret magazine (10) for supporting a plurality of upright columns of cups (14). A pair of part-circular guide surfaces engage the bottom surface of the lowermost cup (14) in each column, the guide surfaces rising uniformly above a horizontal base plate (26) from a region of minimum cup height to a diametrically opposite position of maximum cup height. A fixed, arcuate cam surface (34) is adapted to engage between the rims of the lowermost and next lowermost cups for stripping the lowermost cup from its column. The guide surfaces (20,22) and cam (34) co-operate such that, as the magazine (10) is rotated, the lowermost cup (14) from each column is stripped in turn, lowered to a discharge station (24) and then, if that cup is not required, re-joined to its original column. When a desired cup arrives at the discharge station (24), the rotation of the turret magazine is stopped and that cup is released downwardly to a dispensing station. There is also disclosed a mechanism for the release of selected quantities of a particulate material, such as sugar, to a cup when at said dispensing station. This mechanism comprises a rubber beak valve (40) having a normally closed mouth (50) defined at the junction of a pair of converging, resiliently flexible walls (46), and a plunger (56) which is adapted to be selectively displaceable to engage the beak valve (40) adjacent one end of the mouth (50) and to distort the flexible walls (46) such s to cause the mouth to open and allow the particulate material to flow through.
