  • Patent number: 5586732
    Abstract: The invention was developed in order to effectively crush and disperse various samples easily and efficiently without using any expensive device. By laminating a polyethylene film 3, a net member 7, a net member 9 and a polyethylene film 5 in sequence and welding these members to one another at weld portions 13a and 13b, a bag member 15 is formed. Further by forming a fastener 17 in the vicinity of an opening 15a, a crushing and dispersing bag 1 is completed. After a sample and a dispersing medium are introduced through the opening 15a, the bag is sealed with the fastener 17. Subsequently, when the crushing and dispersing bag 1 is squeezed, the sample is ground by the file-like irregularities formed by the net members 7 and 9 on the inner surface of the bag 1.

  • Patent number: 5585571
    Abstract: A method of, and apparatus for, measuring dynamic torque transmitted by a shaft having an axis of rotation is characterised by the steps of:1 locating on the shaft (S) a pair of transducers (T, T1, T2), each comprising an SAW resonator, as a complementary pair so that for a first direction of rotation (K) of the shaft (S) about the axis (A) one transducer (T1) is under compression and the other (T2) in tension and for a reverse direction of rotation of the shaft the one transducer (T1) is in tension and the other (T2) in compression, a signal input (C1) and a signal output (C2, C3) for either each transducer or a single signal output for a signal derived from both transducers, the signal input and signal output or outputs being located at discrete locations on or near the outside of the shaft (S) for rotation therewith,2 causing a driving signal to be applied to the signal input (C1);3 detecting at each or the signal outlet (C2, C3) at least an output resonant frequency of the transducer (T, T1, T2) when driv

  • Patent number: 5582905
    Abstract: A non-woven mat of fibrous thermoplastic insulation is produced by melt blowing recycled polyethylene teraphthalate (PET). The PET is melted, pressurized and extruded from an extrusion head into substantially continuous fibers that are subjected to turbulent high velocity air that attenuates the fibers. The fibers are then collected on a collection device building up a non-woven mat. The collection device is spaced from the extrusion device forming a flight path for the fibers that is sufficiently long that the fibers split apart under the force of the high velocity air, fibrillating into a plurality of very fine fibrils of under 15 microns in diameter. These fibrils are analogous to goose down and greatly enhance the loft and R value of the mat.

  • Patent number: 5569191
    Abstract: The invention concerns a device for the preparation of a medicinal solution from two components, one of which is in powder, lyophilisate or liquid form and the other a dilutant or a liquid solvent. These components respectively are charged in a rear container (11) and a front container (13), each of which has an opening closed off by a stopper-piston-dish, which is axially movable. Both these stopper-piston-dishes (19, 24) are connected by a conveyance shaft (15) adapted to ensure a rigid, tight and sterile coupling between the two stopper-piston-dishes (19, 24) when the device (10) is in a charging position, and to define a channel between both these containers (11, 13) when the device is in a position of use.

  • Patent number: 5562979
    Abstract: The method involves providing a powdered or granulated plastics paint material which is heated to a plastic condition to form a plastics coating material and injected into a mould. A plastics substrate material is also injected to spread the plastics coating material over surfaces of the mould so as to envelope the plastics substrate material. A moulding is then produced comprising a substrate having a surface coated by the injected plastics paint material. The method enables a moulding to be produced having a painted surface produced in the mould thereby avoiding the need to apply a subsequent paint finish.

  • Patent number: 5560401
    Abstract: A fabric having two images on a front surface thereof. The images are defined by a plurality of parallels, alternating, upper pairs and lower pairs of weft yarns. The upper pairs forming ridges defining the images and the lower pairs forming valleys between each adjacent pair of ridges. A first of the two images being visible when viewing the front surface at an angle from a first direction and substantially invisible when viewing the front surface at angle from a second direction. A second of the two images being visible when viewing the front surface from the second direction and substantially invisible from the first direction. The invention also provides a process for producing the fabric.

  • Patent number: 5560409
    Abstract: A method of resawing elongated radially sawn segments of timber so that bsawn boards are produced. Said wedges are sawn with the desired angle between the radial faces and are resawn so that the growth rings of the tree are basically parallel to the broad backsawn faces. The flared radial edges of the boards indicate the growth ring orientation and therefore the cupping tendency and the direction of bow. This enables a greater degree of consistency in the manufacturing process over conventional methods. Said backsawn boards can be used individually as conventional boards with the mentioned advantages or can be laminated together to make a range of laminates that balance or use the bowing and cupping tendency of backsawn timber.

  • Patent number: 5553576
    Abstract: A motorization unit comprising two internal combustion engines able to run alternately or simultaneously.The two engines (20, 40) each comprise their own cooling circuit (21, respectively 41). These two circuits are each provided with an expansion vessel (26, 46) and are connected to a heat exchanger (30). The purpose of this heat exchanger is to keep the cooling circuit of one of the engines not running, at the right temperature by means of the cooling circuit of the other engine which is running, when the unit is operating in alternate mode.This motorization unit can be adapted to road, rail and aquatic vehicles.
