Abstract: The invention relates to a process for producing a tubular glass membrane with wall thicknesses between 5 and 30 microns and reproducible pore sizes between 11 A and 50 A. Alkali borosilicate glass is drawn into discrete hollow tubes and immediately cooled. The tubes are thermally treated to effect a phase separation into a coherent silicon dioxide phase and a boron oxide phase rich in alkali borate. The boron oxide phase is leached out with mineral acid. The tubes can be subsequently treated to give enlarged or reduced pores, asymmetric pores and coated surfaces.

Abstract: A structural member comprises a soil-retaining sheet having two antipodal edges, means for joining the two antipodal edges when proximately positioned to maintain the sheet in a tubular configuration, and a column of soil retained within the tubular configuration of the sheet. One or more of the structural members when positioned substantially upright can be used to form a pillar. A plurality of horizontally-adjacent pillars can be used to form a wall which together with other walls can be used to form a building particularly adapted to desert location.

Abstract: A stereophonic pickup cartridge includes both a rod-shaped armature and a disk-shaped armature, both of which magnetically interact with the pole pieces of coils to improve the magnetic efficiency of the cartridge.

Abstract: A visual or audible indicator to indicate the absence of an additive ordinarily added to the rinse or wash water of a commercial dishwashing machine is disclosed. The dishwashing machine includes a separate reservoir containing an additive, a supply line connecting the reservoir to the point within the dishwashing machine where the additive is normally added, and a pump in the supply line for pumping the additive from the reservoir through the supply line. The pump includes a check-valve for retaining the additive in the supply line when the pump is not pumping. The indicator includes a vacuum operated switch and a connecting line connecting the vacuum operated switch to the supply line between the additive reservoir and the pump. The pump, switch, and connecting line are physically located above the maximum possible level of additive within the additive reservoir.

Abstract: A system for correcting color balance of a color television picture to remove tinges of color caused by unbalance. Control signals for color correction are derived and stored from data available in those periods when luminosity is below a lower limit of about 7% or above an upper limit of about 95% and when chroma-saturation is below a prespecified level, for example 20%.

Abstract: The present invention relates to an improved getter device with a reduced tendency towards the formation of loose particles and lifting of getter material from its container. One embodiment provides an improvement in the distribution of evaporated getter metal.

Abstract: A structural laminate comprises at least one planar facing sheet with a rigid foam attached to one surface of the facing sheet. The rigid foam may be any polymeric material which is capable of being foamed. Distributed substantially evenly throughout the foam is a mat of long straight glass fibers arranged in layers substantially parallel to the facing sheet. The process for producing this structural laminate comprises the steps of contacting a thin, substantially incompressible yet expansible mat of long straight glass fibers with a foam-forming mixture on each face of the mat, and passing the facing sheets having the mat and the foam-forming mixture there between through the nip of two rotating rolls.

Abstract: An apparatus adapted to be used in conjunction with a conventional cotton harvester for gleaning cotton missed by the harvester consists of a pair of independently suspended, parallel, opposed intake manifolds. Each manifold comprises a floor member having frontward and rearward end wall members fixed at opposite ends of the floor member. An outside wall is fixed to an outside edge of the floor member and extends from the frontward end wall to the rearward end wall. An inside wall having a height significantly less than the outside wall is fixed to the floor member parallel to, but some distance from, the running edge of the floor member. A downfall sheet is fixed to a top edge of the outside wall and to the inside wall so as to be spaced from and inclined with respect to the floor member. The inside wall contains a plurality of apertures leading to forwardly- and upwardly-inclined ducts leading to the flue comprising the inside of the manifold.

Abstract: A method for the formation of inserts in the edge of footwear or shoe soles made by means of injected plastic material, in which either the edge of the sole or the whole sole of the footwear is first moulded by injection, and successively at least a lateral recess is obtained in said edge of the sole itself, and thereafter a differently colored plastic material is injected into said recess for forming a lateral insert in the previously moulded edge of the footwear sole.

Abstract: Oligomeric organo metallic resins which are divalent metal acylates of the formula: X M D M X, wherein each X is an acyloxy ligand of a monobasic acid containing at least 7 carbon atoms; D is a diacyloxy radical (ligand) of a dibasic acid containing at least 6 carbon atoms; and M is a divalent metal atom other than calcium are provided. These novel oligomeric resins are particularly suitable as coating compositions and when they contain oxidizable divalent metals are especially rapid drying.
