Abstract: An apparatus for winding-up croissant dough pieces is provided. It comprises a conveyor (1,3), a pair of pressing boards (11,12), and a spacing mechanism (61,62,71,72,91,92,29,30) having a dough-piece detecting means (4). A triangular croissant dough piece (2) is fed between the conveyor (1,3) and the pair of pressing boards (11,12) and is wound up, while each of the pressing boards is moved laterally outwardly of the conveyor by the spacing means, thereby lengthening both ends of a dough roll as it is being wound up, to shape it into a long and slender croissant dough roll (16). After shaping it, the pressing boards (11,12) are caused to approach each other. The dough-piece detecting means (4) is effective in synchronizing the actuation of the pressing boards with the winding-up operation, so that the wound dough roll (16) is precisely lengthened in its axial direction. <IMAGE>

Abstract: The converter has a three decision range conversion algorithm using ternary values. The converter has a single unipolar reference voltage source (Vr) and computing method (MC) to establish a voltage value. The voltage value is determined by determining a sum value from the voltage calculated during the previous iteration, and a value which is the product of the ternary value during the preceding iteration and the reference voltage. Computing is by switched capacitors (Cr, C1, C2) connected to a single operational amplifier (11). This provides a more compact circuit with less surface integration having a smaller current requirement whilst having a good conversion quality for applications such as hearing aids.

Abstract: A conveyor/cooler of hot loose materials produced by fluid bed boilers and various industrial processes includes one or more feeding channels, which are substantially vertical or at any inclination. Because of gravity, the material leaves the combustion chamber of the boiler. A metallic container is connected to the downstream end of the discharging channels. A metallic conveyor belt driven by a motor is placed within the container, and the material from the downstream end of the channels is laid on the conveyor belt, thus forming a travelling continuous bed. The belt therefore constitutes a regenerative heat exchanger which absorbs heat from the material during the forward run and gives it back to the air during the backward run.

Abstract: A release agent for rolls, particularly rolls in paper making such as press rolls is described which comprises one or more release active components and optionally conventional additives and which is in the form of a microemulsion. Suitable compositions include those which are essentially free from water and to which water is only added before actual application. The microemulsion or the microemulsion, which upon water dilution is at least intermediately formed, is unstable upon dilution with water to the application concentration which results in a good and homogeneous application of the active ingredients to the press surface. In this way the efficiency of the release agent and the release properties of the rolls are improved. Further, less deposits are formed on the roll surface.

Abstract: A process is described for forming a body of whole untreated rice hulls by mixing with a heat setting binder. The mixture is formed into a generally desired formed shape of the body, e.g. in a mold or die. The temperature throughout the formed shape is raised until a parameter indicative of or associated with the start of setting of the binder reaches a predetermined level or is observed. The setting of the binder is progressed beyond the start of setting, preferably under different process conditions, until the binder has substantially fully cured. To raise the temperature of the body, an RF field can be applied to cause dielectric heating within the mixture until condensing steam is seen emerging from the body, whereupon application of the RF field is stopped. Another heating process suitable for a porous body comprises creating a pressure differential through the mass and introducing a heated fluid so that the heated fluid passes through the porous mass. To make a denser body, the heated porous mass can be compressed until setting of the binder has occurred, yielding a stable shape having the increased density.

Abstract: Optical network for signal transfer from a central station to subscriber stations. The signal to be distributed is split in at least two stages, with the signal being amplified by optical amplifiers. The Erbium Doped Fiber Amplifiers (EDFAs) to be used for this purpose are fed by an optical supply signal. By building up the supply signal from various signals with wavelengths lying closely together, Stimulated Brillouin Scattering (SBS) is avoided. As a result, by utilising centrally supplied EDPAs more splitting stages may be applied, as a result of which many more subscribers may be reached from one signal source than before. The subscribers may utilise inexpensive, low-sensitivity receivers. The optical network is particularly suited to form, in conjunction with a conventional non-optical (twisted-pair) network, a hybrid bi-directional transmission system. In this connection, the optical network is intended for the distribution of wide-band signals (CATV) and the non-optical network for bi-directional transfer of narrow-band signals. <IMAGE>

Abstract: A system for generating a liner tube for an underground pipe while material is flowing through the pipe, incorporates a liner winding assembly, a carriage assembly connected to the liner tube being formed, a towing device for generating a pulling force on the carriage assembly and the liner tube being formed, and a liner hub assembly fixedly connected to the liner tube for operatively connecting the carriage assembly with the liner tube. The liner winding assembly includes a feeding and driving device for feeding liner material into the underground pipe, a device for forming the liner material into a liner tube, and a mounting device for fixedly mounting the feeding and driving device and the forming means in the underground pipe. The feeding and driving device generates a driving force to move the liner tube into and through the underground pipe as the liner tube is being formed. The carriage assembly is operatively connected to a front end of the liner tube, and includes a structure for movably supporting the carriage assembly as the liner tube moves into and through the underground pipe. The carriage assembly further generates a torque on the liner tube as the towing device is pulling the carriage assembly. The liner hub assembly is fixedly connected to the liner tube, whereby the pulling force of the towing device translated into the torque of the carriage assembly is operatively exerted on the liner tube releasing the liner tube from obstructions.

Abstract: A method and arrangement for computing and regulating distribution of linear load in a multi-nip calender. A material web is passed through the nips in a set of rolls including a variable-crown upper roll, a variable-crown lower roll and intermediate rolls positioned between the upper and lower rolls. The rolls in the set of rolls are supported so that, when the nips are closed, the bending lines of the rolls are curved downwards. When computing and regulating the linear loads, one or more of the physical properties affecting the bending of each intermediate roll under load, such as bending rigidity, mass, shape, and material properties, are taken into account. The ratio of the linear loads applied to the intermediate rolls, the weight of the rolls per se, and/or the support forces applied to the rolls are regulated so that the set of rolls is in a state of equilibrium and a predetermined state of deflection.
