Patent SE-7703226-L (SE)
IPC: B29B13/00
Filed: 1977-03-21
Abstract: There is provided a mold comprising a male and a female mold member fabricated from thermoplastic polymeric materials which, in very thin sections are flexible under polymerization conditions, but, under said conditions are sufficiently inflexible in thick sections to retain their shape and surface characteristics. Said mold is provided, on either the male or the female member with a thin rim which, during the polymerization process, flexes and permits the old members to approach each other and compensate for the shrinkage that occurs during polymerization. Said thin rim further forms the edge of the finished lens.

Abstract: The invention relates to three-dimensional carriers consisting of inorganic porous material and 0.001-95% of unextractably sorbed reactive polymer of the general formula I:    <IMAGE>   I.  where R1, R2, R4 respectively are hydrogen atom, alkyl with 1-5 carbon atoms, or aryl, and R3 is the group -COO-(CH2)n-, and to a method for its preparation. The three-dimensional carriers may be prepared by coating the inorganic porous material with a monomer, which is left to polymerize under the conditions of solution polymerization, while the soluble polymer, which is not bound on the surface of the inorganic material, is removed by extraction. The three-dimensional carrier may also be prepared by depositing a solution of a polymer of general formula I and with a degree of polymerization lower than 103 on the inorganic porous material, leaving the two materials in contact with each other, and separating the unbound polymer by extraction. The carriers of inorganic porous material-reactive polymer combine good properties of the inorganic material with the high reactivity of the polymeric coating. An advantage of the carrier is not only the combining of inorganic porous materials with a polymer containing epoxy groups, but also an ample opportunity of modifying the carrier by chemical reactions of the epoxy group. This opportunity may be employed in bonding biologically active compounds, dyes, complex-forming compounds and other low-molecular and high-molecular weight compounds to the carrier.

Abstract: An internal combustion engine having in the piston crown or cylinder head a combustion chamber in the shape of a body of revolution with a constricted throat. At the end of the compression stroke, the combustion chamber accommodates substantially all of the air for combustion which is imparted a rotation about the longitudinal axis of the combustion chamber. Taking into account the respectively specified combustion chamber volume, the maximum combustion chamber diameter, the combustion chamber depth, the inclination or curvature of the combustion chamber wall, and the inclination or curvature of the transition from the combustion chamber wall to the combustion chamber bottom are matched in such a way that, utilizing the friction occurring between the combustion chamber wall and the rotating air, a boundary layer or interface flow is produced, resulting in velocity components of a predetermined intensity extending in a direction at least substantially perpendicular to the rotating motion of the air, the velocity components in turn generating secondary turbulence.

Abstract: A solution containing cellulose dissolved in a tertiary amine N-oxide solvent containing a nonsolvent for cellulose such as water is shaped by extrusion or other shaping process to form a shaped cellulose fiber, rod, plate, tubing or film. The extruded shaped article is stretched in air while still a solution to impart improved physical properties thereto and the cellulose is precipitated from the shaped solution to set the properties without additional drawing. The solution may be prepared by dissolving cellulose in the tertiary amine N-oxide solvent in the barrel of an extrusion apparatus, extruding the solution, orienting by stretching the resulting product in air while still a solution and then precipitating the cellulose from the shaped article before significant degradation of the cellulose. The cellulose and tertiary amine N-oxide may be ground to substantially the same particle size before charging the extruder barrel. The tertiary amine N-oxide is recovered and recycled to avoid environmental pollution problems. The resulting cellulose fibers or films can be used to make fabrics, wrapping or packaging materials or nonwoven products.

Abstract: A binary multiplier circuit wherein the product is expressed in coded form as soon as the linear (or non-coded) product is produced. When a twelve-bit binary number in a register 10 is multiplied by another twelve-bit binary number in a register 12 a twenty-four bit binary number is produced in an accumulator register 15. The twenty-four bit product can be coded into an unsigned seven-bit binary number ( mu -255 code) as follows. The number 33 x 2<11> in binary form is preset in accumulator register 15 which at the end of the multiplication contains an augmented product. The number of leading zeroes in the augmented product is counted by a counter 23 which counts clock pulses and is reset by each 1 fed to accumulator register 15, and the base-minus-one complement of the count is formed by inverters 32, 33, 34 and used as the three most significant bits of the coded product. The four next most significant bits of the augmented product, after the most significant logic 1, are, at the end of the multiplication, stored in a latch 26, which is loaded by each 1 fed to accumulator register 15, and four least significant bits of the coded product. A sign bit for the coded product may be supplied at 37. <IMAGE>

Abstract: There is disclosed a hand-held label printing and applying apparatus having an impression control mechanism. The apparatus includes a pair of relatively movable slides. A first slide is driven in response to movement of a manually operable actuator and a second slide which carries the print head is slidably mounted on the first slide. During the initial actuation of the actuator, the first and second slides move as a unit until the second slide is stopped by a shoulder of a latch. Continued movement of the actuator and travel of the first slide causes energy to be stored in a spring arrangement. Upon further movement of the actuator and continued travel of the first slide the latch is tripped and the spring arrangement drives the second slide and causes the print head to be driven into a straight line into printing cooperation with the platen. There is also enclosed an arrangement by which the print head can be releasably connected to the second slide. The apparatus also includes an improved spring assembly.

Abstract: A vortex cleaner for the particular division of paper pulp suspensions into fractions comprising of a continuous two-section circular vortex chamber (1), which over part of its length tapers towards one of its ends. At the further end of the vortex cleaner there is a tangentially directed inlet (2, 6) for the suspension that is to be treated and an axially directed outlet (8) for a lighter fraction. At the more tapered opposite end of the vortex cleaner there is another axially directed outlet for a heavier fraction. The above mentioned first outlet for the lighter fraction is constructed as a coaxially overlapping pipe (8) in the vortex chamber. Through this pipe (8) the light fraction flows out from the vortex chamber as a spiral-shaped eddy current. At the outer end of the pipe (8) there is a device (11) arranged to deflect the spiral-shaped eddy current through the pipe in a radial direction out to a ring-shaped column (9), arranged coaxially relative to the pipe (8) and mainly radially directed, which is fitted in the inner wall of a ring-shaped chamber, arranged coaxially relative to the pipe (8), which is fitted with an outlet that is mainly tangential to the outer wall of the chamber. In this way, a significant part of the kinetic energy of the flow of the fraction travelling through the above mentioned pipe (8) is converted into a pressure in the above mentioned ring-shaped chamber (10), so that the pressure in the pipe (8) becomes lower than that of the ring-shaped chamber (10). Therefore, the input pressure at the inlet (2) to the vortex chamber can be lowered correspondingly, which results in a lower energy consumption for the pump used to input the suspension to the vortex chamber.<IMAGE>
