Abstract: This invention relates to a device at presses for dewatering materials such as peat, digested sludge and other fiber material, which device comprises a belt, which in cooperation with at least one press roll is arranged to apply a press pressure to a material introduced between belt an roll. Certain problems exist here in achieving a high and evenly distributed press pressure over the whole belt width, but this and other problems are solved according to the invention in such a way that the belt consists of a number of separate belt elements (19) located beside each other, each with a cross sectional form decreasing from the side (20) facing the material and with edge portions (23) being in contact with each other, which portions are so elastic that they are opened by the material exposed to the press pressure for discharge of water pressed out of the material.

Abstract: A method for preparing a glass container, and for sealing a glass mouth of a container and the seal are described. The sealing surface, or finish, of the container is subjected to a hot end treatment after forming and before annealing to enhance adhesion between the container finish and a thermoplastic membrane seal. The container is next annealed and after annealing is subjected to a cold end treatment in which the exterior container surface is coated with a material which enhances the lubricity and increases the abrasion and scratch resistance of the container. The container finish only is then subjected to a brief heat treatment sufficient to remove any lubricity enhancing material from the finish. A membrane comprising a thermoplastic film is pressed onto the container finish and heated causing glass-plastic adhesion and forming a closure.

Abstract: The carrier is usable on both straight line and angle posts, where the support insulator has a top clamp. It is fastenable on the top of the insulator in at least two different positions so that it can draw out a line above the insulator top and adsorb a vertical load, and also draw out a line around the insulator top, absorbing a horizontal load. It involves a line wheel rotatably suspended on a fixture which is clamped on the insulator top, and turnable so that the wheel can take up either vertical or horizontal loads. A pair of line wheels are positioned on opposite sides of the insulator top and joined by a yoke. The yoke is connected to a fixture clamped on the top of the insulator, permitting absorption of vertical and horizontal loads by the wheels. (Provisional Basic advised week 84/02)

Abstract: Wet ash removal apparatus comprises an endless conveyor having drive input means (5) driven by an electric drive motor (6) through an hydrostatic regulating gear (7), the conveyor being arranged to circulate in a trough (1) of the apparatus. The hydrostatic regulating gear (7) is provided with a pressure monitor (14), which acts on a setting drive (16, 17). A setting lever (17) of the setting drive is connected with a gear shift lever (13) at the hydrostatic regulating gear (7). On a change in the pressure of oil in the regulating gear, a change in the output rotational speed of the regulating gear is effected automatically through the setting drive. Thus, an increase in the quantity of ash causes increased oil pressure resulting in an adjustment of the displacement of the pump of the hydrostatic gear (7) so as to increase the speed of the conveyor. <IMAGE>

Abstract: A continuous feed, solid bowl centrifuge with intermittent rim discharge. The centrifuge has first and second members mounted in fixed positions relative to each other for rotation about a common axis. Each member has a peripheral edge portion extending about the common rotational axis with the portions being spaced from each other to create an annular gap therebetween. A third or rim member is mounted for rotation with the first and second members about the common rotational axis. The rim member has a cylindrical surface extending between the peripheral edge portions of the first and second members and is dimensioned to close the gap therebetween. The rim member is supported with its cylindrical surface substantially parallel to the rotational axis of the centrifuge; and, an opening-closing mechanism is provided that maintains the cylindrical surface substantially parallel to the rotational axis as it is moved to open and close the gap. The cylindrical surface is the only portion of the rim member exposed to the high, multi-directional fluid pressures of material being centrifuged. In this manner, the opening-closing mechanism for the rim member does not have to work against any force components generated by the centrifuged material other than radially directed ones which are uniformly directed against the cylindrical surface and offer relatively inconsequential resistance to the movement of the rim member. The rim opening means does not rotate with the centrifuge thereby simplifying the power transfer to it and adding no weight and imbalance problems to the rotating centrifuge.

Abstract: An arrangement for controlling the tension in the saw-blading (5, 6) of a bandsaw equipped with an electrically controllable blading-tensioning arrangement by means of which the blading can be stretched so as to adjust the tension therein to a desired level. To this end, the arrangement includes automatically operating devices (8-13) which are operative to determine whether or not the blading-tension is optimal during a sawing operation. These devices are intended to sense and determine mutually different parameters, such as specific blading-tension, disturbances in the movement pattern of the blading, the linearity of the saw cut, etc. The arrangement also includes a microprocessor (9) which is operative to process the electric signals corresponding to the sensed parameters. The microprocessor is programmed to send control signals to the blading-tensioning arrangement when the microprocessor establishes deviations from limit values programmed therein with respect to the parameters or fluctuations of these parameters, thereby to adjust blading-tension in a manner to reduce these deviations or fluctuations. The invention also relates to a method for controlling the tension of sawblading.

Abstract: The present invention relates to a method and apparatus for through-connecting data information in a digital selector. It is known to use selector memory devices in digital selectors for the purpose of through-connecting data information. When using selector memory devices in accordance with present day techniques, for instance in selectors of the T-S-type (Time-Space), a large number of selector memory devices are required, which results in problems relating to space and effect. The problem is solved by means of the inventive method and arrangement, since one single selector memory device according to the invention replaces several selector memory devices of known kind. According to the inventive method, data information enters a selector memory device distributed on time slots. Data information is written into the selector memory device during one write phase for each time slot. The data information written into the selector memory device is read therefrom during read phases belonging to the time slots, wherein for read-out purposes two or more read phases are arranged for each write phase. Read-out is controlled for each read phase by a separate control memory device.

Abstract: Channels contain programmes, access to which by viewers is controlled. The programme channels are fed into a distributer which divides the signals to six controllable down-converters which convert the frequencies of the channels to a mean frequency, e.g. 38.9 MHz. The down-converters are followed by a series of up-converters which convert the signals from the mean frequency to a number of distribution channels. Finally, the signals are reconnected together in a combiner, and transmitted into the distribution network, using cable and/or radio medium and/or optic fibre. A subscriber administration computer controls which programme channel is to be transmitted on the respective distribution channels. This can be changed so rapidly that no viewer has any possibility of manually following the channel shifting process.
