Tub sizes for paper, containing aqueous or aqueous-alcoholic alkali metal, amine or ammonium salt solutions of copolymers of maleic anhydride and diisobutylene and, if appropriate, a vinyl monomer of the formula ##STR1## in which R designates H, --CH.sub.3, --C.sub.2 H.sub.5, --OR.sub.2, --OCOCH.sub.3, ##STR2## --CH.sub.2 OH or --CH.sub.2 --O--COCH.sub.3, R.sub.1 designates H or --CH.sub.3 and R.sub.2 designates alkyl, the anhydride groups of the copolymers being bis-esterified to the extent of ...

A stapler includes a base having a first end portion and a second end portion, a first staple magazine having a first end portion pivotally connected with the first end portion of the base and a second end portion formed with a closed face and containing a staple ejection slot on the bottom portion thereof, a second staple magazine received in the first staple magazine and having a first end portion connected with the first end portion of the first staple magazine and a second end portion, a plu...

New aqueous sizes, in particular paper sizes, are made available which contain (a) ketene dimers of the formula ##STR1## in which R.sub.1 and R.sub.2 can be identical or different and represent hydrocarbon radicals having 6 to 30 carbon atoms, (b) amine-modified starch, (c) hydrophobic compound(s) which contain(s) one or more functional groups which are reactive towards OH groups within a pH range of 2 to 6, and (d) if desired further auxiliaries.

Novel sizing compositions comprise an aqueous mixture of the reaction product of urea with selected Lewis acid, and a rosin that is modified with from about 5 to 50 percent based on the weight of the rosin, of an organic acidic compound selected from the group consisting of an .alpha.,.beta.-unsaturated organic acid, an anhydride thereof, and their mixtures. The selected Lewis acids which can be employed are sulfuryl chloride, chlorosulfonic acid, thionyl chloride, benzenesulfonyl chloride, benz...

A size for textile fiber which comprises a modified polyvinyl alcohol type resin obtainable by the alkali saponification of a copolymer comprising a vinyl ester and an ethylenically unsaturated dicarboxylic acid substantially free from the monoester, diester and anhydride as essential and predominant copolymeric units. The size has excellent adhesive and cohesive strengths with respect to textile fibers as well as superior desizing properties and workability.

For measuring the sizes of particles in the falling state, electromagnetic waves having different frequencies are transmitted from a transmitter/receiver onto the particles in the falling state and reflected electromagnetic waves having different frequencies reflected from the particles in the falling state and received by the transmitter/receiver. Data of the distribution of sizes of the particles and the average size of the particles are derived from the detected intensities of the received re...

The invention relates to a process for measuring particle size by measuring the attenuation of radiation after its passage through a defined measuring section containing a disperse system. According to the invention the temporally fluctuating transmission signal is recorded with variable time or spatial resolution. The transmission signals recorded then undergo a non-linear operation. The result of that non-linear operation is represented and analyzed as a spectral curve, i.e., as a function of ...

A reusable case for storing, transporting and merchandising bottles of alternatively first and second different sizes. The case has opposing open first and second ends and a shelf secured therein and midway between the ends. First and second different divider structures are formed on opposite respective sides of the shelf. The first divider structure, with the first end oriented up, defines within the case and on the shelf a first plurality of pockets for retaining bottles of the first size. Alt...

A basket style article carrier having bottom, side and end walls together with telescoping medial and handle panels forming a medial longitudinal strut is provided with transverse partition panels interconnected between the medial longitudinal strut and the side walls, the transverse partition panels being spaced so as to form end cells of the same size and form a center cell of a different size on one side of the medial strut and which on the opposite side of the medial strut transverse partiti...
