Abstract: Method of restoring or making a conveyor channel or pipeline for medium under pressure, especially water, along an already existing cavity (1) formed of a section of a damaged and untight conventional pipeline or consisting of recesses in successively arranged elements, preferably of insulating material. The new feature resides in drawing in a hose-like lining (4) including a covering (5) of durable, pressure-absorbing, untight material which is generally unelastic and has no tendency to expand and contract axially but is elastic and expandible to a limited degree in the peripheral sense, said covering (5) including an inner layer (6) which is tight, elastic, soft and resistant to the material being conveyed.

Abstract: A valve arrangement which is especially designed for district heatign systems and can be laid in the ground comprises a valve (1) which it should be possible to open and close by rotary movements. The bonnet (11) of the valve body and the valve stem (8) have connections (13, 15-17) which are located above the insulation (18), as is the stuffing box (14). The valve is combined with a bonnet extension (20) and a stem extension (21) which can be attached via the connections and which form a pressure-free upper part. The valve is thereby given a structural height such that it can be actuated and its position indicated at the plane (36) of the ground by means (22) at the upper end of the pressure-free part.

Abstract: A mechanism to be utilized for winding wire on a spool in tight coils without space between them. The mechanism includes rotating devices (14) and (16) which when activated rotate the spool (12) about its longitudinal axis (13). A wire guiding unit is arranged to be automatically moveable in all directions to the side of the thus rotating spool. The unit comprises a pressure roller (2) or equivalent which with a predetermined force presses that section of wire which during winding runs inwards at an angle against that section of wire which comprises the previous coil of wire in the layer being wound. During winding the pressure roller (2) adjoins and presses the section of wire being wound against the last wound coil of wire and the mantle surface of the spool or the already wound underlying layer of wire.

Abstract: Apparatus for reducing the noise immunity of a tone selective receiver to prevailing noise conditions in a mains network, through which signalling takes place between a network unit and a plurality of terminal units subordinated to it, all of which are connected to the network. The tone selection circuit 3 sends a data flag signal DF, the duration of which is measured in a first time measurement circuit. If this duration is short relative the duration of the tone of the transmitted tone signal, more and more capacitors are connected into an intergrating circuit 7 included in the tone selection circuit. The integrating circuit 7 thus determines the noise immunity of the tone selection circuit, until short-duration DF signals are no longer detected. The invention includes the use of a large number of capacitors C1-C2n in the integrating circuit. In a corresponding manner the capacitors are disconnected stepwise each time a second time measurement circuit has determined that no interference has occurred during a given predetermined time period following the connection of a new capacitor into the integrating circuit.

Abstract: The type of transmitter used is of the broad band type, and comprises a local oscillator (10) and one stable (11), and a back-coupled shift register or so-called pseudo noise register controlled by the stable oscillator (11). A multiplier (13) partly receives the carrier wave from the local oscillator and partly the pulse signal from the pseudo noise register. An amplifier (14), and an aerial (15) for transmission of the phase-modulated signals produced by the multiplier are also provided. The oscillator frequency can be from 1-30 MHz and the pseudo noise shift register frequency can be 0.1 MHz, giving a pulse length of 10 micro-seconds. The shift register produces a pseudo-random pulse sequence of alternating positive and negative pulses. In the multiplier are multiplied the produced carrier wave and the PN register pulse sequence, the positive signal from the register signifying that the carrier wave is unaltered, whilst the negative signal shows that the carrier wave has been phase-switched through 180 degrees.

Abstract: The table (1), in the work position, is fixed relatively to the machine (7) and a movable input table (2) has its gables forming the front parts of a pair of levers (18) pivotably suspended on the fixed table around a first horizontal rotary axis (10). The levers are counterbalanced by a pair of hydraulic cylinders (20). A second horizontal rotary axis (35) is provided in the feed-in table front end, around which the blade unit (3) is suspended pivotably. A sensor emits impulses if the blade unit is turned upwards through a specific angle around the second rotary axis. Controls of receipt of the sensor impulses activate the hydraulic cylinders so that the levers are turned around the first rotary axis. The feed-in table is thus raised allowing the blade unit to move freely away from an obstruction.

Abstract: The present invention concerns a reinforcement unit 2 intended to be used for making a so-called top reinforcement. Reinforcement units according to the invention can be laid out quickly and ensure minimum use of steel. The reinforcement units are very simple to produce since no welding needs to be carried out, and for this reason the cost is kept low. Because there is no welding, there is no reduction in the stability of the reinforcement bars. A further advantage is that no so-called spreader bars are needed for holding the bars at the right level above the form face, and no special spacer members are needed on which to lay the bars. Projecting outwards from a reinforcement bar, or a similar reinforcement element extending along the intended reinforcement, and towards a casting form 1 or other bearing member, there is a bent reinforcement support 5 which is formed by the end 4 of the bar etc., which is angled 6 sidewards in relation to the longitudinal extent of the bar. The reinforcement support 6 is formed by a branch bent out horizontally from the bar, and extending between the said branch 6 and bar 2 there is an upright 5 which is at an acute angle in relation to the branch 6, and bent in towards the bar to form an acute angle 7 between the upright 5 and the bar 2. <IMAGE>

Abstract: The dimensioning of a ground water well is obtained by investigating the yield characteristics of the ground water region by conducting a series of pumping runs using an observation tube in stepwise pumping cycles of short time intervals (15 seconds to 20 minutes), and measuring the hydrostatic height of the water of each run, finding the yields as a function of the level drop. The yield of the production well, compared with the yield of the observation tube, is found from the ratio of the strainer sections and observation tube, using a predetermined empirical factor corresponding to the different sizes of the strainer. In the case of ground water deposits at very great depth, the yield may be explored by an inverted method in that water is pumped into the ground and the hydrostatic pressure is measured with different pumping rates.

Abstract: A method and apparatus are provided for increasing the efficiency of treatment of a paper pulp slurry with chlorine gas, such as in the bleaching or delignification of deciduous wood chemical pulps, coniferous wood chemical pulps, and non-wood fibrous chemical pulps. Chlorine gas is intimately mixed with the pulp in a fluidizing mixer (14), the pulp preferably having a consistency of about 7-12%, and then is passed to a retention vessel (20). The discharge of pulp from the mixer to the retention vessel, and from the retention vessel to other treatment structures, is throttled by valves (30, 31) so as to increase the pressure in both the mixer and the retention vessel to above atmospheric, and preferably in the range of about 15-150 psig (1 to 10 bar above atmospheric pressure). The chlorine gas is added to the mixer through one more discs (53) of porous materials having pore sizes in the range of about 5-175 microns, such as porous ceramic or sintered metal discs. The increased pressure during the chlorine treatment, and the introduction of the chlorine gas in the form of minute bubbles, improve the solubility of the chlorine in the pulp slurry and thereby increase the efficiency of treatment.
