Abstract: Described is a filter apparatus (10) which is designed for filtering solid, liquid or gaseous, electrically uncharged or electrically charged particles out of a gaseous flow medium as it flows through the filter apparatus (10). The filter apparatus (10) has filter elements (18) which are spaced from each other in the direction of flow of the gaseous medium to the apparatus. Each filter element (18) has a plate-like carrier element (20, 46, 48; 64) and a substrate (22) which are provided with spaced-apart openings (26). The substrate (22) serves for the storage of a filter medium. Each opening (26) in the filter element (18) has a sleeve-like guide element (24) for the flow medium, wherein the guide element (24) extends around the edge of the corresponding opening (26). The guide elements (26) which project at least at the upstream side prevent filter medium at the individual substrates (22) from being unintentionally entrained through the openings (26), even at high flow rates in respect of the flow medium.

Abstract: A method of inserting a rivet having at least a body portion and a mandrel having means for cutting and peeling back the rivet into portions which curl back on the rivet body into a solid substance. The rivet and mandrel are inserted into the solid substance without completely piercing through the solid substance. The rivet is then cut and peeled back into portions which curl back on the rivet body within the solid substance. The invention is also directed to a product comprising a solid substance, and a material fastened to the solid substance by at least one rivet which extends through the at least one material and into the substance without completely piercing through the substance. The at least one rivet has been cut back into portions which curl back on the rivet body, thereby attaching the material to the solid substance.

Abstract: A process is disclosed for treating water or solids contaminated with a nitro- or nitroso- substituted compound comprising reducing a nitro- or nitroso- substituted compound in the presence of an effective catalytic amount of at least one of a corrin- or porphyrin- metal complex. The present invention is particularly useful in treating waste water or soil contaminated with nitro- or nitroso- substituted compounds.

Abstract: A system for adding and withdrawing solids to a high pressure reactor wherein there is provided improved control of flow and concentrations of a slurry of solids in a transport oil for introducing and withdrawing solids from the reactor. In addition, there is provided for improved heating and cooling of the solids.

Abstract: An electrical outlet box having a ring portion which is fitted within the outlet box and a cover which has a downwardly depending circular portion which mates with the ring. The downwardly depending circular portion has outwardly extending tabs which fit into grooves in the inner wall of the ring. Each tab has a groove which interlocks and mates with a protrusion extending from a wall of the groove included in the ring. The interlocking provided which enables the cover to be secured to the outlet box as well as enabling the cover to be easily removable from the outlet box. Thus, an outlet box is provided which enables one to remove and replace the cover easily, and also provides for interchangeable covers.

Abstract: A method of treating a fruit-based or vegetable-based beverage to remove chill haze components therefrom which comprises contacting the beverage with an effective amount of an amorphous hydrous precipitated synthetic magnesium silicate which has been treated to reduce the pH thereof to less than about 9.0. Such a method is particularly applicable to the treatment of beer and related beverages and provides for improved removal of chill haze components from such beverages.

Abstract: A process for treating water or solids contaminated with at least one chlorinated phenol which comprises oxidizing the at least one chlorinated phenol in the presence of an effective catalytic amount of a corrin- or porphyrin-metal complex. A preferred catalyst is a complex of Fe.sup.3+ ion with protoporphyrin known as hematin. Chlorinated phenols which may be oxidized include those found in hazardous wastes such as chlorophenols, dichlorophenols, trichlorophenols, tetrachlorinated phenols, and pentachlorinated phenols.

Abstract: A process for the manufacture of alkylbenzenes wherein a feed of fresh and recycle benzene and fresh olefin are reacted in the presence of an alkylation catalyst in an alkylator having at least two reaction stages wherein each stage is adiabatic. Essentially all of the olefin is completely reacted in each stage of the alkylator. Fresh olefin is fed into each stage of the alkylator. Preferred alkylbenzenes which are produced by this process are ethylbenzene and cumene.

Abstract: An apparatus for dispensing a predetermined amount of a sample into a fluid. The apparatus comprises a chamber which may be inserted into a cuvette. The chamber comprises a membrane or filter ball for dispensing a predetermined amount of a sample into a fluid upon contact of the membrane or filter ball and the sample by the fluid. The fluid is brought into contact with the sample by vortexing the fluid with a vortex mixer.

Abstract: An air intake installation for the carburetor system of an outboard motor is in the form of an elongate duct e.g. 9, 13a, so configured, located or equipped as to prevent water reaching the carburetor system even if the vessel capsizes. Preferably, a tube 9 (flexible to permit steering or tilting the motor) communicates with rigid under-deck elongate buoyancy spaces forwardly open at 14 and optionally gravity-valved at this open end to close on capsizing.

Abstract: A display article including a display portion and a support portion. The display portion includes folding panels which are movable from a first position to a second, or display, position upon contact of the folding panels with the support portion, with the support portion retaining and supporting the folding panels in the second, or display, position.

Abstract: A vaccine for protecting against a disease caused by a microorganism which does not synthesize nucleic acid precursors such as a Micoplasma organism, which contains nuclease and/or a nuclease fragment or derivative which produces antibodies which recognize nuclease secreted or available on the surface of the microorganism against which protection is to be afforded. A vaccine may also be prepared from an antibody or fragment or derivative thereof which recognizes such nuclease of such microorganism.

Abstract: A process for producing coke from a combined feed. The combined feed is initially provided as a first portion which comprises easily cokable components and a second portion which is essentially free of easily cokable components. The first portion is heated to a temperature lower than that normally employed by a coking heater in a delayed coking process. The second portion is heated to a temperature at which a combination of the first and second portion provides combined feed at coking temperatures. The combined feed is then subjected to coking conditions.The first portion, in one embodiment, may be comprised of a fresh feed and the second portion may be comprised of a coker recycle. In another alternative, a fresh feed and a coker recycle are combined and fractionated to produce the first portion and the second portion. The first portion may include components which boil above a temperature of about 900.degree. F., and the second portion may be essentially free of easily cokable components.

Abstract: An improved process for the alkylation of benzene in the presence of an alkylation catalyst. The catalyst bed may be caused to move in a direction countercurrent to the movement of the benzene and olefin, or a portion of the catalyst bed is periodically removed and replaced. A regeneration step, whereby the catalyst is heated in a controlled oxygen atmosphere in order to reactivate the catalyst, is also described.
