Abstract: At least one continuously arriving product stream of printed products is to be transferred to the infeed paths or lines of two or more processing stations. To ensure that the distribution of the arriving product stream can be accomplished as continuously as possible and accommodated optimumly to the requirements of the processing stations, the product stream is guided such that it crosses the infeed paths. At the crossings or cross-over locations the product stream is at least periodically delivered to a storage device and at the same crossings or cross-over locations printed products are simultaneously transferred out of the storage device and at a transfer location delivered to an infeed location of the associated infeed path or line. Thus, at each crossing there is present an intermediate store or buffer of products which, on the one hand, renders possible a continuous conveyance of the product stream and, on the other hand, affords a continuous mode of operation of the processing stations.

Abstract: The invention relates to a middle beam for a window frame having an inner metal profile insert and a facing spar which covers the latter on at least three outer sides, the profile insert being connected by means of screw connections in the region of its two front ends to frame elements of the window frame. According to the invention, such a middle beam is to be designed in such a way that it can be manufactured in a more cost-effective manner and be simpler to assemble and offer the possibility of subjecting the middle beam to substantially greater loading without altering the cross-section of said beam. This is achieved according to the invention in that the profile insert (1) consists of two identical profile halves (2, 3) but which are arranged in mirror image fashion to one another, these halves having the basic form of a "U" and being arranged relative to each other by the base limb, each base limb 2 having beads (4, 5) running parallel at a distance to one another in the longitudinal direction, which beads together form two screw channels (6, 7).

Abstract: For the controlled ventilation of a room a duct portion (8) with a quantity control and measurement means is provided in the ventilating duct. The duct portion (8) surrounds a tubular hollow body (25) in the form of a flow body, which has two pressure measuring chambers (29, 30) arranged successively in the flow direction. They are provided with rows of openings (27, 28), which produce a connection to the flow cross-sections with different flow speeds. The quantity is measured by means of a differential pressure measuring device (20), which is connected by means of ducts (32, 33) to the pressure measuring chambers (29, 30). The apparatus has low flow losses and a low flow noise. As a result of its favorable flow guidance the apparatus can be positioned directly adjacent to branches of the ventilation duct.

Patent NL-85708-C (NL)
IPC: C08F20/28
Abstract: The esterification product of a polymerizable alpha-beta unsaturated carboxylic acid and a polyglycol monoalkyl ether is polymerized in bulk with or without one or more copolymerizable vinyl compounds in the presence of a redox polymerization catalyst.  The polymerizable mix may also include preformed polymers, e.g. polymethyl methacrylate, dyes and fillers such as titanium, zirconium or zinc oxide.  The esterification product may be the methacrylate of diglycol monomethyl ether, or of polyglycol monomethyl ether made by reacting ethylene oxide with diglycol monomethyl ether in the presence of metallic sodium and esterifying the product with methacrylic acid.  Copolymerizable compounds mentioned are bis-diglycol monomethyl ether maleinate, diethylene glycol dimethacrylate, and esters of acrylic and methacrylic acids.  The catalyst may be a mixture of tributylamine, or p-toluene sulphinic acid with benzoyl peroxide. The process may be used in dental prosthesis.
Patent NO-151229-C (NO)
Inventor: PATTEE HARRY EDVARD
IPC: B23K20/08
Filed: 1980-05-09
Abstract: There is disclosed a method for the explosive welding together of sections of large diameter metal pipe of the kind used in the construction of high volume oil and gas pipelines. In the method, internal and external band charges of welding explosive are simultaneously detonated adjacent to overlapped telescoped pipe ends. The explosive band charges have a tapered or wedged shape in the width cross-section of the band and are placed so that the thicker edge of the band is closed to the narrow diameter of the female flared pipe area and initiation is made along the thicker edge. The velocity of detonation of the initiating explosive is selected so that welding charges are simultaneously detonated around the pipes while maintaining the detonation fronts at superimposed locations and at a large angle to the pipe axis. This avoids unbalancing forces on the pipes and minimizes the collision of circumferential shock waves thus preventing pipe damage and imperfect welds.

Abstract: A process has been developed for preparing the sodium, the monoethanolamine and the diethanolamine salts of piroxicam, in which the salt is deposited on a pharmaceutically-acceptable carrier. The compositions so obtained are useful for preparing pharmaceutical dosage forms of piroxicam, from which piroxicam is rapidly absorbed from the gastrointestinal tract after oral administration to mammals. These latter dosage forms are particularly suitable when it is desired to use piroxicam as an analgesic agent, where rapid onset of action is necessary.

Title: Lenses from polymeric derivatives of acrylic and methacrylic acids
Inventor: KRCOVA ZUZANA
IPC: C08F20/00
Filed: 1989-12-07
Granted: 1998-04-07
Abstract: An object of the invention is a lens made from a non-hydrophilic acrylate or methacrylate polymer or copolymer and designated for application in a water medium inside a human eye or on its surface, i.e. an intraocular or contact lens, the originally non-hydrophilic surface layer of which was additionally hydrophilized by a partial hydrolysis or sulfonation in such a way, that the gradient of swelling results where the swelling continuously changes from its maximum on the very surface to the minimum in the non-swelling core unaffected by hydrophilization. In this way, light reflexes are removed or at least substantially reduced as well as the tendency to the surface growth of cells, irritation of neighbouring living tissues, and the formation of pressure necroses.       Strong inorganic acids are most suitable for the surface hydrolysis. Their ability to swell and dissolve the employed acrylate polymer can be arbitrarily limited by dilution with water or by addition of well soluble salts. The thickness of hydrophilic layer is controlled in this way and also by the time of action.       The surface hydrophilic layer may be crosslinked by simultaneous esterification with multifunctional alcohols, in the molecule of which remains after esterification at least one additional free hydrophilic group.

Title: Time division multiplex system and method having a time slot reuse capability
Inventor: RODRIGUES MANOEL A
IPC: H04L12/52
Filed: 1990-07-30
Granted: 1998-10-06
Abstract: A multi-user Time Division Multiplex (TDM) system includes a plurality of stations and at least one erasure node located between groups of the stations. When a station reads the destination identification bits of a received time slot and determines that it is the destination for that slot, it sets the status of a slot-read bit, which follows the destination identification bits, to indicate that the slot has been read. When an erasure node detects a set slot-read bit it erases all or part of the associated slot, thereby enabling the reuse of that slot by subsequent stations. An interface apparatus, which enables the TDM system to connect the other TDM systems, filters intra-system communications from inter-system communications using the slot-read bit. When the interface apparatus detects a set slot-read bit it knows that the slot has been read and, therefore, is an intra-system communication which should be blocked or discarded. Since inter-system communications have notbeen read, the slot-read bit is not set and, consequently, the interface apparatus routes that slot to one of the other TDM systems as determined by the destination identification bits of the slot.
