Abstract: A menses collector adapted to be used during coitus for the collection of uterine discharge at the cervix thereby to isolate the same in a pocket retaining absorbtive material and preventing the same from entering into the vaginal vault. A removeable cover of supple material is attached to a pliant diaphragm, there being a yieldable opening in the cover to seal with the cervix opening therethrough into said pocket, and there being a rim at the perimeter of the diaphragm to seal with the vaginal walls and stabilizing the device between the fornix and the pubis symphysis.

Abstract: A low velocity high torque gas turbine, using the Brayton Cycle, and having a high velocity compressor with a separation of the working fluid into two columns, one external for cooling and the other internal for primary fuel injection and combustion. A feature is the recycling of a proportion of the combustion gases that is then combined with the external column of heated cooling air for secondary fuel injection and combustion. The primary and secondary combustion fluids are comingled, the diffused and separated column of cooling air being advantageously employed to supply an excess of oxygen in the working fluid to adequately support combustion. The tubular turbine shaft for recycling combustion gases, and the working fluid distributor that combines the primary and secondary working fluids, and the speed increasor for the compressor, all characterize this invention.
