Abstract: Devices are described that reduce pain associated with menstruation and other conditions and that operate by pressing upon the sacral/parasacral regions of a woman's lower back. In preferred embodiments a tensioning apparatus applies pressure onto a generally flat part that distributes force into the sacral and parasacral regions but avoids the lumbar region. The devices may assume a variety of forms such as belts, straps and foundation garments that can exert high pressures and may exceed 100 torr in some cases.

Abstract: A media feed mechanism includes a picking device, a first feedroller and a second feedroller. The picking device picks a sheet of media from a media source. The first feedroller moves the sheet of media along a feed media path. During a skew correction phase, the first feedroller rolls in a forward direction feeding the sheet of media forward and the second feedroller turns in a reverse direction preventing the sheet of media from progressing past a nip of the second feedroller. This results in skew correction. After skew correction is performed, the second feedroller turns in the forward direction advancing the sheet of media for printing.

Abstract: The disclosure provides a breast supporter which can be worn or held to a person's breast to provide protection and comfort, and particularly to reduce discomfort during or following breast implant surgery. The breast supporter can provide one or more depressions or cups for resting of breasts, wherein the breast supporter can be inflatable, and wherein the size(s) of the depression(s) or the cup(s) or the opening(s) is/are adjustable.

Abstract: In order to reduce discomfort induced by menstruation, a panty girdle or the like type of foundation garment is provided with an extensible bladder or a non-extensible element which is arranged to apply pressure to one or both of the sacral or parasacral areas of a female body. In the case of the extensible bladder, the pressure can be varied through the manual manipulation of a squeeze pump that may be built into the waistband of the garment. The garment is additionally provided with an elastic foundation panel that is shaped and designed to reduce bloating and create a trimmer appearance.

Abstract: In order to reduce discomfort induced by menstruation, a panty girdle or the like type of foundation garment is provided with a distensible bladder which is arranged to apply pressure to one or both of the sacral or parasacral areas of a female body. The pressure can be varied through the manual manipulation of a squeeze pump that may be built into the waistband of the garment. The garment is additionally provided with an elastic foundation panel that is shaped and designed to reduce bloating and create a trimmer appearance.

Abstract: A catalyst composition is disclosed that is useful for the dimerization of a normal 1-alkene containing 3-8 carbons. A supported alkali metal is employed as a catalyst and is combined with about 10-100 mol %, based on the amount of alkali metal catalyst, of an oxide of sodium, potassium, rubidium, and/or cesium as a co-catalyst. In preferred embodiments of the invention, the alkali metal is potassium or a potassium or a potassium alloy, and the co-catalyst is sodium oxide.

Abstract: An alkene selected from ethene, propene, and mixtures thereof is coupled with an aromatic hydrocarbon having an active hydrogen on a saturated alpha-carbon in the presence of a supported potassium or potassium alloy as a catalyst and cesium oxide as a co-catalyst. In a preferred embodiment of the invention, the active hydrogen-containing aromatic hydrocarbon is an alkylbenzene, such as toluene.

Abstract: A normal 1-alkene containing 3-8 carbons is coupled with itself, another such alkene, or ethene in the presence of a supported alkali metal as a catalyst and about 10-100 mol %, based on the amount of alkali metal catalyst, of an alkali metal hydroxide as a co-catalyst; the support being a silica having a surface area not greater than 5 m.sup.2 /g. In preferred embodiments of the invention, the alkene is propene or a mixture of propene and ethene, the alkali metal is potassium or a potassium alloy, and the co-catalyst is potassium hydroxide.

Abstract: A catalyst composition having enhanced effectiveness in coupling an alkene with an aromatic hydrocarbon having an active hydrogen on a saturated .alpha.-carbon is obtained by dispersing an alkali metal onto a supported oxide of sodium, potassium, rubidium, cesium, barium, strontium, calcium, or magnesium in the absence of a diluent.

Abstract: A controlled air incinerator includes a primary and secondary combustion chamber. Combustion by-products from the primary chamber are exhausted to the secondary chamber. In the secondary chamber a source of auxilliary heat is provided to maintain the temperature in that chamber at a point which is sufficiently high to fully combust any particulate and unwanted gaseous matter. The secondary combustion vessel is provided with a baffle means for increasing the residence time of combustion by-products in the secondary chamber. The baffle means comprises an arch preferably oriented concave downwardly, the inlet to the secondary chamber being situated beneath the arch. The baffle means means increases residence time and increases the turbulence of gases passing through the secondary chamber.

Abstract: Vinylidene olefins are selectively removed from a mixture of olefins containing vinylidene olefins by reacting the mixture with either hydrogen sulfide or a hydrocarbyl mercaptan and then distilling the resultant mixture to obtain a substantially vinylidene olefin-free product.
