Patent SE-8105180-L (SE)
Inventor: VALOIS R J
IPC: D03D51/34
Filed: 1981-09-02
Abstract: A precise, accurate and sensitive control method and system for actuating the stop motion mechanism of a weaving loom equipped with a weft yarn storage feeder unit is disclosed. The storage and feeder unit includes a device for applying tension to the weft yarn being delivered from a weft yarn supply to the storage and feeder device. The tension device is equipped with a switch which provides a first electrical signal when the weft yarn being supplied to the storage and feeder device becomes slack or interrupted. That switch is connected with the weft yarn storage and feeder unit motor circuit. The weft yarn storage and feeder unit may be intermittently driven as the need occurs for feeding a weft yarn length or pick into the loom. The loom is stopped only in the presence of two concurrent signals, namely (1) a signal generated upon the detection of slack weft yarn or the absence of yarn in the tension device and (2) a simultaneous signal indicating operation of the motor to drive the weft yarn storage and feeder device. By the operation of the loom stop motion mechanism only in the presence of the aforementioned simultaneous signals, short picks, i.e., insertion of weft yarn lengths less than that required to extend from one side of the fabric being woven to the other, is precluded. Further, false signals which might arise from simple slackening of the yarn in the zone of the tension device are not operative to halt the loom.

Abstract: A method and an equipment for wireless transmission of telephone calls between a stationary unit (1) connected to a telephone set (3) at a short distance from the stationary unit provides that all pairs of units (1, 3) have access to a plurality of common duplex radio speech channels for transmission of calls, and to a common radio signalling channel for transmission of signals referring to connection and disconnection of the speech channels. The radio speech channels are assigned after adaptive channel scanning in that they are listened to before a call, and a channel selected which is idle with respect to calls. The selection of an idle channel takes place automatically with the use of radio receivers (12, 25), channel selectors (15, 28) and circuits (16, 29) incorporated in both units.

Abstract: The invention refers to a method for neutralizing and utilization of surplus acid which is retained as a by-product from the production of chlorine dioxide through the reduction of chlorate with sulphur dioxide or chloride in an acid solution. This method is characterized by the fact that one carries out neutralization of the surplus acid with a base containing magnesium, preferably carbonate, possibly in a mixture with lime or limestone. The base containing magnesium can be dolomite or dolomite limestone but can even be magnesite, magnesium oxide, magnesium hydroxide or the like. The method is especially suited for taking care of surplus acid especially during the Mathieson process and the then obtained solution of magnesium and sodium sulphate can be directly transferred to the oxygen bleaching step in the pulp mill.<IMAGE>

Abstract: Engines having cylinders of noncircular cross section wherein the cylindrical curve is generated at a preselected constant outwardly normal distance from a closed curve. The closed curve is defined as including two spaced points on a major axis of symmetry of the cylinder with two continuously curved portions extending between these points and curved outwardly from the major axis. The closed curve about which the cylinder curve is generated is preferred such that there is a continuous change of curvature without discontinuity in that curvature in the cylindrical curve. The avoidance of discontinuity in the generating curve aids in mass production consideration and cutter life. A plurality of intake and exhaust port arrangements are disclosed illustrating four intake ports and four exhaust ports on opposite sides of the major axis of symmetry of the defined cylinder. In one embodiment, the outermost of the ports are smaller and are positioned closer to the major axis of symmetry. In another, the valves are oriented such that the stems thereof point to the centerline of the associated camshaft for direct actuation.

Abstract: The different layers can pref. be provided as a number of coloured formations, and can be arranged widthways to each other on e.g. a self-adhesive tape, so that each is clearly visible to the human eye. A tape strip with a length of 5 cms thus provides a personal identity number, in which 10 colours are clearly distinguishable, even where some are merely shades of others, having a width of 5 mm. A variant arrangement is where the layers are arranged one on top of the other, so that each part layer has to cover that beneath it. To render the layers visible to the naked eye, or with the aid of a magnifying glass or microscope, each layer constellation takes the form of small particles. To achieve this, the coloured layers are painted on to each other, after which they dry and harden to a decomposable layer, from which colour particles are mixed in a solvent medium. Such a solvent should pref. have etching characteristics, at least on plastics material.

Abstract: There is disclosed a fifth wheel trailer coupling comprising a saddle having a coupling plate 1, in which wearing members 4 are arranged on the coupling plate at least at surface regions thereof which are greatly exposed to abrasion in service. These wearing members increase the service life of the coupling plate by strengthening the regions which are exposed to considerable wear, as a result of continuous friction with the usual steel supporting plate, particularly in the vicinity of bearing pockets on the outer marginal region of the coupling plate. The wearing members are introduced into the most highly stressed regions in the top of the coupling plate, and may be cast into the coupling plate or mechanically joined thereto. The service life of the coupling plate is therefore extended, with consequent economies. <IMAGE>

Abstract: An apparatus for collecting fish eggs comprises a conveyor for transporting fish with the upper half of each fish inclined obliquely upward, a pair of upper and lower conveyor belts for holding the tail of each fish therebetween during transport, a pair of upper and lower conveyor belts for holding the trunk lower half portion of each fish therebetween during transport, trunk support portions and fish back restraining frames arranged alternately on the lower trunk holding belt, a head cutter disposed close to the terminal end of the conveyor, a member for pressing the abdomen of each fish after its head has been cut off, and an operating mechanism for the pressing member. During transport on the conveyor, the eggs in the abdominal cavity of each fish move toward the tail of the fish under gravity, and the head is thereafter cut off by the cutter. During the subsequent transport operation, the fish has its abdomen pressed by the member, is bent rearward about the portion thereof held by the trunk holding belts and is prevented from being further bent by the restraining frame in bearing contact with the back of the fish. The member therefore fully exerts its pressure on the fish to completely squeeze out the eggs from the head cut-off face for collection.
