摘要:
For supplying production and packaging machines, in particular for supplying lines (10, 11) for producing and packaging cigarettes, an intermediate store (12) is provided for storing packaging material, to be precise for pallets (20) with reels (18) of web-like material. Pallets (20) with the packaging material are fed to the intermediate store (12) by a pallet conveyor (28). A separate reel conveyor (48) transports reels (18), as required, to the individual machines and subassemblies of the lines (10, 11).

A process and a device for severing wrappings (11) in each case surrounding a stack (10) of blanks and for removing the wrappings (11). To guarantee that they are held together better, stacks (10) of blanks are surrounded by a strip-shaped wrapping (11). In the region of a wrappings station (19), these are severed by a horizontally movable knife (23). The knife (23) enters into the upper area of an upright limb (12) of the wrapping (11), between upper blanks of the stack (10) of blanks, and is moved along a guide rail (25) whilst severing the wrapping (11). The latter is subsequently drawn away downward by a drawing force.

Stacks of blanks (10) comprising a largish number of pre-fabricated blanks made of (thin) cardboard are usually made available on pallets (12). The stacks of blanks (10), provided if necessary with a band label (11), are aligned on the pallet (12) in rows (13) and disposed in a plurality of layers (16) the one above the other. A pick-up head (18) serves to unload the stacks and is movable on a support structure (19), configured like a portal, in a vertical and in a horizontal direction. The pick-up head (18) grasps respectively one group of stacks of blanks (10) and sets same down on an onward conveyor (14).

The invention relates to water-insoluble polymers which promote cell proliferation, contain carboxylate and sulfonate groups and are obtainable by free radical copolymerization of one or more aliphatically unsaturated monomers containing carboxylate groups, or the correspondingly functionalized derivatives of the monomers, as component I with one or more aliphatically unsaturated monomers containing sulfonate groups, or the correspondingly functionalized derivatives of the monomers, as component II and a component III which comprises an aliphatically unsaturated monomer or several aliphatically unsaturated monomers, the correspondingly functionalized derivatives being converted into carboxylate and sulfonate groups after the copolymerization, and to a process for their preparation, wherein the polymers are useful for forming articles which promote cell proliferation.

A noise control method is provided for a cooling system having at least one refrigerant circuit. The refrigerant circuit includes a compressor, a condenser, at least one condenser fan, and an evaporator. Noise control is only performed periodically in response to requirements for reduced operation at predetermined times. The request for reduced noise triggers the commencement of the noise control method. The noise control method involves reducing the operating speed of the compressor, as well as reducing the operating speed of at least one condenser fan, to within a predetermined range of allowable reduced operating speeds. The noise control method temporarily overrides the ability of the cooling system to fully respond to increased cooling or heating demands. When the noise control method is terminated, such as by the end of the stated period of time requiring reduced noise generation, the system is restored to normal operation, and remains fully responsive to cooling and heating demand until commencement of the next period of reduced noise requirements.

摘要:
Antimicrobial activity is imparted to the surface(s) of an apparatus or article by a method, comprising: copolymerizing tertbutylaminoethyl methacrylate with at least one other aliphatically unsaturated monomer in the presence of said apparatus or article by which adhesion of the copolymer to said surface(s) is achieved. In an embodiment of the invention, adhesion of the polymer coating on the apparatus or article occurs by graft copolymerization.

A rear-view mirror wiper system for wiping moisture from a rear-view mirror includes a vehicle. The vehicle has a pair of rear-view mirrors. A pair of wiping units is provided. Each of the wiping units is coupled to an associated one of the rear-view mirrors. Thus, each of the wiping wipes moisture from the mirror of the associated rear-view mirrors thereby enhancing visibility.

The invention relates to water-insoluble, bacteriophobic and optionally cell proliferation-inhibiting polymers obtainable by free-radical polymerization of (a) at least one monomer of the general formula R—(A)a, in which R is an aliphatically unsaturated organic radical with the valence a, A is a carboxyl group —COOH, sulfuric acid group —OSO2OH, sulfonic acid group —SO3H, phosphoric acid group —OPO(OH)2, phosphonic acid group —PO(OH)2, phosphorous acid group —OP(OH)2, a phenolic hydroxyl group or a salt of one of the groups, and a is 1, 2 or 3, with the proviso that, if the monomer of the formula I contains a carboxyl group —COOH or a carboxylate group, either this monomer contains at least one further radical A having a different one of the definitions specified for A, or at least one further monomer of the formula I is also used in which A has a different one of the definitions specified for A; and (b) at least one other aliphatically unsaturated monomer, wherein the polymers are useful for forming bacteriophobic or cell proliferation-inhibiting articles.
