A seal kit for vehicle air conditioning systems and associated methods are provided. The seal kit includes a container and a set of a plurality of retrofit seals positioned in the container and adapted to retrofit a set of a plurality of existing seals of any one preselected group of different vehicle air conditioning systems corresponding to a preselected group of different vehicles. The seal kit simplifies and shortens the selling cycle by condensing multiple similar vehicles' seal requirement...

A method of manufacturing and supplying a net-moulded article of expandable syntactic material and a related shipping package are provided. The moulded article is formed at a manufacturing facility where the forming process can be controlled to ensure production of quality syntactic material articles. The moulded article is formed by dispensing the material into a mould having a cavity with a shape matching that of a desired syntactic article to be used in an assembly at a point of use. The moul...

An improvement in the process for producing acrylic or methacrylic acid by the vapor phase catalytic oxidation of a system containing acrolein or methacrolein, respectively, is provided. The improvement resides in the employment, in such process, of a novel catalyst prepared by admixing with a solution of the catalytic components an organic substance, for example from the group of organic acids, alcohols, amines, esters and quinones, drying the admixture and subsequently calcining the admixture ...

A thermal detector includes a transducer layer of semiconducting yttrium barium copper oxide which is sensitive at room temperature to radiation and provides detection of infrared radiation. In a gate-insulated transistor embodiment, a layer of ferroelectric semiconducting yttrium barium copper oxide forms a gate insulator layer and increases capacitance of the transistor or latches the transistor according to the polarization direction of the ferroelectric layer. The transducer layer may be for...

Disclosed is an oxidation catalyst which is particularly useful for the conversion of unsaturated aldehydes to the corresponding unsaturated carboxylic acid. The catalyst has the following empirical formula Mo.sub.a V.sub.b W.sub.c Mn.sub.d O.sub.e.

In a machine for filling and closing tubes, an endless conveying line has equispaced gripping members for loading tubes with vertical axis and with open bottoms turned upwards. The line is operated stepwise for transferring the tubes, one by one, to subsequent stations arranged along the line for carrying out operations of cleaning inside the tubes, orienting outer prints, filling the tubes with measured quantities of product, closing the bottoms, applying codes, and possibly trimming the tubes....

The present invention relates to a process for preparing acrylic acid by oxidizing acrolein and to an oxidation catalyst. More particularly, the present invention relates to a catalyst and a process for preparing acrylic acid by oxidizing acrolein or a mixed acrolein gas obtained by vapor phase oxidation of propylene with molecular oxygen in the presence of an oxidation catalyst of the empirical formula: Mo.sub.a V.sub.b T.sub.c A.sub.d O.sub.e Wherein Mo, V and O represent molybdenum, vanadium ...

The present invention relates to a catalyst composition consisting of oxide complexes of vanadium, molybdenum and copper plus an additional metal oxide selected from the group consisting of antimony and germanium or mixtures thereof. These catalysts are especially useful for producing acrylic acid from acrolein and for producing methacrylic acid from methacrolein.

A plastic pulsation bag for automobile gasoline filters and a method of making the same is disclosed. The bag comprises two opposing flexible membranes peripherally sealed together along their opposing sides. At least one of the opposing sides is recessed so that a pocket is formed by the sealed membranes for enclosing a gas which is preferably heavier than air. In a preferred method, a first step in forming the bag is to slopingly insert the membranes into an open-top chamber containing a body ...

A packaging system includes an outer bag having an inner bag suspended therein to define an expandable chamber between the bags and one either side of the inner bag. When the chamber is charged with a filler medium, such as pressurized air, the outer bag will inflate to suspend the inner bag at a fixed position therein. The inner bag defines a pocket adapted to receive and retain an article, prepackaged therein.
