Title: Process and apparatus for packaging a stack of flat objects
Inventor: WINNEMOELLER ALOYS
IPC: B65B11/12
Filed: 1992-02-06
Abstract: To package a stack of flat objects, preferably a stack that is composed of bags provided with handles and has a height exceeding the width of a bag, the stack is wrapped by a section of a web of paper of plastic and the marginal portions of the web section which overlap on one side face of the stack are adhesively bonded to each other to form a tubular wrapper around the stack. The end portions of the wrapper which protrude from the ends of the stack are folded onto the end faces of the stack so as to form folded corner portions, which are folded onto and adhesively abonded to one side face of the stack. To permit a packaging by means of simple apparatuses, one side portion of each protruding end portion of the tubular wrapper is first folded onto the adjacent open end face of the stack about the longer edge of said end face, the adjacent ends of each protruding end portion of the wrapper are pulled out and flattened into the plane of the infolded side portion so that the apposite side portion of the protruding end portion is folded about the opposite longer edge of the adjacent end face of the stack onto said end face and folded corner portions protruding from the stack are thus formed. Folded corner portions are then folded onto and adhesively bonded to the wrapper on those side faces of the stack which adjoin the initially open side face of the stack.

Title: Resin kernels and foam-like material containing reactive media and method of making same
Inventor: WOOG MANFRED
IPC: C08J9/00
Filed: 1992-03-27
Abstract: ABSTRACT           A porous substance containing a reactive material and the related method for making the substance is pro-vided.  The method includes establishing a resin substance which is porous and inert to liquids in a vessel.  The resin substance is then impregnated with finer particles of a reactive material.  The reactive material is chosen such that an ionic exchange reaction will occur when a liquid to be treated is passed through the particles.  After the reactive material is added to the resin substance, the resulting mixture is cured by heating or by the addition of a catalyst or a combination of both heating and a catalyst.  Kernels may be formed which have a sponge-like configuration and which contain the reactive particles within the supporting resin substance.  Solutions may be passed through the kernels for filtration, purification, or reactive purposes.          Alternatively, the substance can be poured into a treatment vessel while still in liquid form and it is then allowed to harden in situ.

Patent CA-2077278-A1 (CA)
Inventor: ESCHBACH REINER
IPC: H04N1/405
Filed: 1992-09-01
Abstract: Gray pixel values, where the value of the pixel has one of a relatively large number of input levels, are directed through an error diffusion quantization process, for the conversion to one of a relatively small number of values. Each pixel of the gray level data is modified by a correspondingly weighted error correction term or terms from previously processed pixels, generating a modified pixel value. This modified pixel value is compared to a threshold value, the threshold value determined adaptively, based on 1) a dither pattern, having a dynamic range greater than 1, and 2) the value of the pixel to be thresholded, and optionally on its predetermined neighborhood, multiplied by a value representing an edge enhancement factor. The difference value between the modified pixel value and the output pixel value is distributed in accordance with a weighted distribution scheme to a set of neighboring unprocessed pixels, increasing or decreasing the gray values of such pixels.

Title: Process and device for manufacturing plastic mouldings
Inventor: EYERER PETER
IPC: B29C67/24
Filed: 1991-04-29
Abstract: ABSTRACT           In a process for manufacturing plastic mouldings from a reactive foam material such as polyurethane, at least two liquid reactants are mixed while incorporating finely dispersed air, and the resultant reaction mixture is injected through a gate into an assembled cavity of a mould, displacing the air in the latter and causing a build up in internal pressure in the mould which decreases as the distance from the gate increases, and hardens by chemical reaction in the cavity to form a moulding.  To improve the mechanical properties of prefabricated parts and to smooth the surface pores, the internal pressure in the mould in at least one region, preferably remote from the gate, already filled with reaction mixture is increased shortly after the end of injection and the reaction mixture, which is in a gel-like transition state, is compacted, the air inclusions being compressed and/or released.
