Foaming is reduced during the preparation of beer by adding to wort or beer a silicone antifoam material, followed by removing the antifoam material by contacting the beer with an adsorbent whereby foaming capability is restored to the beer.

A device, including a base, adapted to be adjustably and removably secured on a horizontally disposed operating table. An upwardly inclined support will support the leg bent at an angle, preferably less than 45.degree. at the knee, with the knee elevated and both the upper and lower legs in a substantially vertical plane and free from obstruction to clear visibility, and access to the lateral sides of the knee, and also free from obstruction to lateral movement of the leg. The support is also ad...

The addition of a mixture of alkali metal sulfite and thiosulfate to a drycleaning solvent containing a bleaching agent destroys any excess bleaching agent, thus preventing degradation of the textile fabric being drycleaned, without detrimental side effects.

An appliance for protecting edge portions of floor coverings, for example carpets, during the painting of adjacent parts of walls, skirting boards and the like is described. The appliance consists of a generally rectangular thin aluminum plate whereof one long edge is flanged through 90.degree. to form a narrow lip for insertion between a carpet edge and an adjacent skirting board. On the plate, adjacent each end of the lip, stops projecting oppositely from the lip serve to prevent over-reaching...

An early warning detection method for predicting abnormal formation pressure, generally geopressure, in subterranean rock strata before it is drilled. The technique is to measure the concentration of the bicarbonate ion in the formation being drilled, while the well is being drilled in the normally pressured rock strata existing above the abnormally pressured formations. When variations are observed in the degree of change of the amount bicarbonate ion present with depth, drilling procedures are...

A device adapted to be fastened to slab saws or the like for holding stones or similar objects during cutting, said device comprising a generally vertical back plate, a pair of horizontal, spaced support arms extending outwardly from the back plate and adapted to cradle the object being cut, and a hold-down member pivotally connected to the back plate avove the support arms and including a pair of spaced fingers in biased engagement with the object to be cut to hold it firmly in place.

A fetal extractor comprising a first plate member defining a front concave surface adapted to be adhered to part of the head of a fetus by means of an adhesive previously placed on the head of the fetus or on said surface, a second plate member substantially parallelly positioned with respect to said first plate member, bearing balls, a ring retaining said plate members and said bearing balls assembled to only permit relative rotary movement of one plate member with respect to the other about an...

Gas shielding is employed to prevent metal plating on contacts during electroplating to reduce particulate contamination and increase thickness uniformity. In another embodiment, gas shielding is employed to prevent deposition on the backside and edges of a semiconductor wafer during plating.

The cooling device comprises a supply chamber disposed around a vertical duct and having a front wall which at a spacing intimately follows the shape of the vertical duct, and an evacuation chamber disposed around the supply chamber and separated therefrom by an intermediate wall. The front wall is formed with a number of passages extending towards the vertical duct. Some of these passages open into the supply chamber and the remainder of the passages are connected to tubes which extend through ...

The present invention involves a method of producing cellulose. This method comprises inoculating a quantity of nutrient medium comprising a polysaccharide derivative such as carboxymethylcellulose (CMC) with a cellulose-producing microorganism. The inoculated medium is then aerobically incubated to facilitate the production of cellulose. The step of substantially drying the cellulose may be added for certain products. Substantially dried cellulose resulting from this procedure is highly absorbe...
