Patent SE-7703734-L (SE)
Inventor: AATINEN E
IPC: F16C13/00
Filed: 1977-03-31
Abstract: A roll, of the type used in papar machines, is manufactured by rotating an inner roll body around its axis while simultaneously winding onto the outer surface of the inner roll body an elongated metal strip the convolutions of which press against each other so as to cover the outer surface of the inner roll body at the area of this outer surface onto which the strip is wound.  This strip has an inner edge surface engaging the outer surface of the inner roll body, an outer edge surface distant therefrom, and opposed side surfaces extending between the inner and outer edge surfaces.  At each of the wound convolutions of the strip the opposed side surfaces thereof respectively engage, over their entire areas, the adjoining side surfaces of adjoining strip convolutions over the entire areas of these adjoining side surfaces.  At any instant during the winding of the strip onto the inner drum body, the strip has an end convolution an inner side surface of which presses against the immediately preceding convolution and an outer side surface of which is exposed at one end of the series of convolutions which have already been wound.  A compressive force, which is directed parallel to the axis of the inner roll body, is applied against the outer side surface of this end convolution, during winding of the strip onto the inner roll body, at a location extending inwardly from the outer edge surface of this end convolution along the outer side surface thereof toward but terminating short of the inner roll body.  The magnitude of this compressive force is sufficiently great to deform and elongate the end convolution at the location thereof to which the compressive force is applied.

Abstract: A sack-formed package is constituted by a cover 10 comprised of flexible material and a string-shaped device 13 that extends from a bottom part of the cover, up through the packaging space formed by the cover and out in a manner that allows displacement relative to the upper part of the cover through an opening in the same, from which device 13 the packaging can be supported, whereby the stresses that arise from the act of support are essentially completely absorbed by the lower part of the cover. In order to facilitate filling, and where relevant, emptying, an arrangement 23 that can be controlled from the outer surface of the package is provided to temporarily prevent displacement of the upper part of the cover relative to the string-shaped device in the direction of the bottom part of the cover. <IMAGE>

Abstract: The invention relates to a dosing pump for a car washing machine. Dosing of detergent and similar in such machines has previously been done by injecting detergent into the water being applied to the vehicle. This has demanded relatively large amounts of diluted detergent in order to obtain a satisfactory admixing. In order to reduce the amount of detergent and thereby enable use of concentrated preparations, use is according to the present invention proposed of a system comprising a simple and uncomplicated double pump, which is inserted such that the outlet 19 of one pump chamber may be connected to a choked pipe 32 conducting the detergent into a water supply pipe, while the outlet 20 of the other pump chamber may be connected to a return pipe 31 and vice versa, resulting in the piston feeding out liquid from one of the pump chambers to the water pipe relatively slowly, while the return movement takes place quickly. <IMAGE>

Abstract: The present invention resides in the manufacture of an AlMg alloy sheet with zinc addition which is readily deformable in the soft condition and especially suited for shaping into motor vehicle body components. The alloy sheet has a strength of at least 250 N/mm2, a grain size of less than 50  mu m and, after deformation has occurred, remains free of surface defects such as orange peel effect and Luders bands and also, after a possible influence of heat, remains insensitive to stress corrosion cracking. The zinc addition produces a widening of the working range so that after the last cold rolling operation the alloy can be soft annealed above the recrystallization temperature without coarse grains or Luders band appearing. The zinc addition produces an insensitivity with respect to stress corrosion cracking after a heterogenization annealing subsequent to the soft annealing, even after a sensitization at 150 DEG  C. on a sheet which has been deformed with a cold reduction of 20% and more.

Abstract: A conduit-break valve for a double hose or conduit is designed to operate under a higher pressure between the hoses or conduits than that prevailing in the inner hose or conduit and than that of the ambient atmosphere. The valve has a valve member (16) which is urged by a spring (24) towards its valve seat (15). A diaphragm or piston device (18) normally maitains the valve member (16) in open position by the action of the pressure in a pressure chamber (22) which is connected to the space between the hoses. At a break of the inner and/or the outer one of the hoses or conduits the pressure in the pressure chamber (22) is reduced and the valve is closed by the action of the spring (24).

Abstract: Communication between portal units and identification tags is accomplished by continually radiating an interrogation signal consisting of a code pattern from each portal unit followed by a listening interval. Tags within range of such interrogation signal test the incoming signals for frequency, bit duration, bit rate, a preamble code and a facility identifying code. If the tag receives a valid signal to which it has been preprogramed, such signal synchronizes and initiates a plurality of tag responses within a given overall response interval and with each response transmitted during randomly selected time slot. Each tag is provided with its own pseudorandom binary sequence generator and reply counter with the pseudorandom generator sequenced by a signal derived from the carrier signal radiated by the tag. The portal units also test incoming signals for frequency bit rate and bit duration as well as for a preamble code generically indicative of a tag. If the test is passed, the remaining tag response consisting of an identifier and an error correcting code is accepted and passed on to a CPU.
