Inventor: GUSTAFSSON ALF
IPC: H01F27/42
Filed: 1986-05-16
Granted: 1993-05-14
Abstract: The invention relates to a method and to an arrangement for controlling the respective conduction times of two directionally opposed electrical devices (9, 10) which are mutually connected in parallel and permit current to pass therethrough solely in one direction, and which also permit current (l<sub>2</sub>) to pass through the primary winding (2) of a transformer during a respective half-period of an A.C. voltage (U,) applied to the primary winding, this control being effected so that the magnetizing current through the transformer can be advantageously minimized and/or held beneath a given limit value when an asymmetric load (4, 5) is applied to the secondary side (3) of the transformer. A magnetizing current in the primary winding corresponding to the load (5) of the secondary winding (3) is controlled through the agency of different conduction times of the two directionally opposed devices (9, 10).

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.

Title: Method of preraring ribonuclease dimers
Inventor: HERRMANN PETER
IPC: A61P31/04
Filed: 1990-01-08
Abstract: A method for preparing purified ribonuclease dimers is provided which comprise the steps of dimerizing monomeric ribonuclease with a suberimidate coupling reagent, filtering out undimerized monomers and oligomers from the dimer solution using a series of ion exchange resin chromatography steps, monitoring the progress of the reaction through gel electrophoresis, and collecting the purified ribonuclease dimer product. The method is advantageous in that large amounts of the dimeric product can be obtained efficiently and relatively inexpensively, and the ribonuclease dimers so produced can be employed for their beneficial effects in combatting viral and bacterial infections without the cytotoxic effects normally associated with the ribonuclease monomer.
