Abstract: An apparatus for inverting and returning sheets from a printer (1) for large-sized paper comprises an inlet area (11) where the sheet is received from the printer (1), and an outlet area (12) where said sheet is returned to the printer (1). The apparatus comprises a frame (16) mountable on the support of the printer (1), and a guiding slit (18) in the inlet area, said guiding slit being defined by an upper wall (13) and a lower wall (17), where the lower wall (17) extends from the inlet (11) to a clamping slit (22) between a first pair of roller means (23, 24) for receiving and temporarily retaining the front edge of a sheet when seen in the advancing direction, said sheet being received through the inlet area. The lower guiding wall (17) is tiltable and adapted to be moved about a substantially horizontal axis from a sheet-supporting position to a downward sheet-releasing position.

Abstract: A heating element (4) is arranged between two temperature sensors (5, 6) in order to measure the mass flow of a liquid or a gas. The mass flow is determined from the temperature difference of the temperature sensors (5, 6). The heating element (4) is operated by pulses in order to reduce power consumption of the device. A further reduction of the power consumption is reached by means of a monitoring circuit (12), which switches the actual measuring section (11) on only if the signals from the temperature sensors (5, 6) fulfil a threshold condition.
Abstract: A system for selection by a user and delivery to the user over an internetwork transmission channel of selected audio data files at a delivery rate of at least twice the delivery rate for normal, audibly perceptible playback of an audio data file. The user registers the user's selection of audio material with a central library of audio and/or text data files, and a digitized and optionally compressed omnibus file containing the user's selections is prepared and transmitted to the user at a high data transfer rate. The user receives downloads the selected data files to a personal computer or to a portable storage and playback unit (SPU) that may store and play back digitized text or audio data, using a docking station. The user carries this SPU until the user has an opportunity to audio process and play back the text or audio data files in audibly perceptible form.

Abstract: The object of the present invention is to prevent the encroaching and the seizure between the bolt and the female screw caused by an oblique screwing of the bolt into the female screw when the bolt and the female screw are fastened together. Another object of the present invention is to manufacture the bolt in a low cost, by using said bolt, the encroaching and the seizure between the bolt and the female screw caused by a oblique screwing of the bolt into the female screw are certainly prevented. Said objects may be attained by a bolt consisting of a column part and a polygonal pillar part extending from an end of said column part wherein a complete thread is formed on said column part and a screw blade continuing to said complete thread is formed on said polygonal pillar part.
Abstract: The object of the present invention is to provide a molded plastic article having high accuracy. To attain this object, the present invention provides a method of manufacturing a column or panel shaped molded plastic article having a desired molding shape on at least the circumference face of said molded plastic article comprising; manufacturing a column or panel shaped mother mold by using a material having high rigidity and heat resistance, the circumference face of said mother mold has a shape corresponding to the molded shape of the circumference face of said molded plastic article, manufacturing a cylindrical or ring shaped glass mold by the glass molding method, the inside face of which has a shape transferred from said shape of the circumference face of said mother mold, and molding a molded plastic article, circumference face of which as a shape transferred from said shape of the inside face of said resulting glass mold.
Abstract: A self-sacrifice type metal corrosion inhibitor is prepared by dispersing one or more kinds of metal powder having a greater ionization tendency than that of a metal to be treated and a water-insoluble thermoplastic resin powder in water containing a water-soluble anticorrosion agent, a surface-active agent and a thickener to from a treatment solution. The treatment solution is applied to the surface of the metal to be treated, which is heated to melt the thermoplastic resin powder and form a thermoplastic resin layer fixed to the surface of the metal. It forms a metal corrosion-inhibiting layer fixed to the surface through the thermoplastic resin, which acts as an adhesive layer.

Abstract: First pivot bodies are received for rotation in first recesses in the housing member. A piston member is mounted in a eccentric portion of the drive shaft such to orbit in operation. Second pivot bodies are received for rotation in second recesses in the piston member. Dividing vanes are inserted at their ends in slots, formed in the first and second pivot bodies in a free floating manner such to reciprocate in operation of the engine. These vanes define a number of combustion chambers. The ends of the vanes received in the first pivot bodies of the housing member perform pivoting movements and the ends received in the second pivot bodies of the piston members perform orbiting movements. Thus, only small frictions and wear at the vanes in and the pivot bodies occur and the engine can be designed with small dimensions.
Abstract: A masking member is provided that can be used repeatedly even for surface treatments at a high temperature. The masking member includes a plastic produced by polymerization using a metallocene compound as a catalyst or a polymer alloy containing such a plastic.

Abstract: The object of the present invention is to prevent the sticking of the heat sensitive transfer recording film without generating head refuse and further to prevent transfer obstruction. More particlarly, the present invention provides a compound comprising a polydimethylsiloxane copolymer and one or more synthetic resin(s) selected from a group consisting of polyvinyl acetate derivatives, polyamide, acrylic resin, epoxy resin, unsaturated polyester resin and precursor of unsaturated polyester and/or cellulose derivatives; and sticking proof agents containing said compound; and a heat sensitive transfer film having a sticking proof layer formed by using the agents.
Abstract: An assembly for processing blanks comprises a first endless conveyor (1) with locations for holders for the blanks and at least one stationary processing station as well as optionally a second conveyor (6) arranged next to said first conveyor (1). The first conveyor (1) comprises a number of self-propelled vehicles (2), where each vehicle carries a tool (4) and a holding device (3) for the blank device. The first conveyor (1) comprises at least one guiding line (19) marked on the running surface (18).

Abstract: The drum of the drum unit has a plurality of jacket walls. One jacket wall is designed as a freely pivotable lid. A cam disk is located in the drum. In certain positions the lid rests at its free end on the cam disk such that it is controlled by same. When the drum rotates in one direction, the cam disk blocks the lid in its open position such that an automatic discharging of the drum takes place. At a rotating in the opposite direction the lid remains closed due to its force of gravity, so that neither a manual manipulation nor operating apparatuses for a moving of the lid are needed.

Abstract: An antenna comprises a signal radiator, a ground plane spaced apart from the radiator, and a dielectric separator between the radiator and the ground plane. The separator comprises at least two positions having different dielectric constants. In a preferred embodiment, it comprises a material such as FR-4 that has a dielectric constant and a loss tangent substantially higher than those of air and is formed with at least one void reducing the loss tangent of the separator. The antenna strikes an effective compromise between the dielectric constant and loss tangent and is well suited to transmit and receive GPS signals.
