Title: Process for the production of wood-chip panels or the like and a corresponding double-band press
Inventor: AHRWEILER KARL-HEINZ
IPC: B27N3/24
Filed: 1988-10-07
Granted: 1992-09-29
Abstract: ABSTRACT            In a double-band or similar press the pressure on the mat (10) that is being fed in is increased so rapidly as soon as this mat comes into contact with the heat-transfer surfaces (1, 2) that the outer areas of the mat (10) hardens under the great pressure, whereas the heat has still not penetrated into the interior of the mat (10).  This results in an enhancement of the surface quality of the panel (P).  As an example, to this end, a roller gap (17) can be provided before the feed gap (13).     (Figure 1)

Abstract: ABSTRACT OF THE DISCLOSURE     Described is photochromic particulate material comprising a photochromic substance within a matrix of a polymerizate of a polyfunctional acrylate monomer.  The photochromic particulate material may be produced by adding an organic photochromic substance to a polymerizable composition including a polyfunctional acrylate monomer and polymerizing the resultant admixture, e.g., by emulsion polymerization. in the case of emulsion or suspension polymerization, finely divided particulate organic photochromic materials are separated from the polymerization medium in the form of spheroidal thermoset photochromic particles of fairly uniform size.  If desired, the particles recovered from the polymerization medium may be further ground in conventional attrition mills to further reduce the size of the particulate product.          In the case of bulk polymerization, the polymerizate may be formed as a continuously cast sheet, which is then pulverized to a particulate material of pigmentary size.

Abstract: ABSTRACT      A paper transfer feed separator automatically separates paper-drive edge tear strips from paper forms along perforations.  The paper transfer feed separator may be hand-held and motor driven for removing the paper drive edge tear strips after the paper form is removed from a printer, or the like, or incorporated into a printer so that separation of the edge strips occurs simultaneously with printing on the paper.  The frame of the separator causes a divergence in the paths of the body of the form and the edge paper strip to cause separation thereby, eliminating the need for knife blades or other elements requiring maintenance.

Abstract: Gem-disubstituted cyclohexadienone in which the gem substituents are a perfluoroalkyl group and a trihydrocar-bylsiloxy group are prepared by perfluoroalkylating a quinone with a perfluoroalkyltrihydrocarbylsilane in the presence of an active catalyst under essentially anhydrous conditions, preferably in a suitable liquid phase reaction medium, most preferably in a dipolar aprotic solvent.          These gem-disubstituted compounds are readily convertible to perfluoroalkyl-substituted aromatics and thus provide a means of circumventing the traditional need for photo-chlorination followed by halogen exchange in the prepara-tion of such products.

Abstract: Abstract DNA probes to detect Campylobacter jejuni and Campylobacter coli were prepared from a bacteriophage .lambda.gtll library by screening using an antiserum directed against a C. jejuni 46 kilodalton major outer membrane protein (MOMP).  Two DNA fragments (MOMP DNA probes) were identified, cloned into pUC13 and characterized by restriction endonuclease digestion (Figure 1).  One MOMP DNA probe (pDT1720) hybridized only to C. jejuni strains, whereas the other (pDT1719) hybridized to both C. jejuni and C. coli strains.  The invention DNA probes can be used to specifically identify the aforementioned bacterial species when the species designation is in doubt and can also be used to identify the microorganisms directly in stool specimens, as disclosed herein. 28  Claims,  1 Drawing

Abstract: A computing system is presented which includes an application object, a computer based training instruction object ("INSTRUCTION object") and an agent engine. The INSTRUCTION object runs concurrently with the application object. The application objects includes a first action processor and a first command processor. The first action processor receives messages which indicate syntactic actions taken by the user and generates semantic commands based on the syntactic actions. The first command processor receives the semantic commands from the first action processor and executes the semantic commands.      The INSTRUCTION object receives input from a user through syntactic actions and displays information on a monitor. The information instructs a user as to operation of the first application. The INSTRUCTION object may include an INSTRUCTION action processor and an INSTRUCTION command processor. The INSTRUCTION action processor receives messages which indicate syntactic actions taken by the user and generates semantic commands based on the syntactic actions. The INSTRUCTION command processor receives the semantic commands from the INSTRUCTION action processor and executes the semantic commands.      The agent, running a task language program, sends semantic commands to the INSTRUCTION object which direct the INSTRUCTION object as to what information to display.      The agent also monitors the application object and the INSTRUCTION object, intercepting semantic commands before they are executed.

Abstract: In one of the methods, connecting elements made by using concrete are produced by first pouring a fluid mortar, on the inside of a wall (1), into openings (5) of a template (2), with the addition of an adhesion promoter. A bell- or disc-shaped casting mould, which is filled with earth-moist concrete and is centred by the openings, is then placed upon this fluid mortar. The form elements thus produced can be stacked for hardening, with the interposition of thin plates, and subsequently joined to form form-element halves, for example by adhesive bonding. Modified methods produce the form elements by using dumbbell-shaped connecting elements made with the aid of axially separated mould halves. Form elements produced according to the method permit numerous modifications. <IMAGE>
