Abstract: Dans une série de plaques (5, 6) d'échange de chaleur, chacune étant rectangulaire avec des orifices (7, 8, 9, 10) dans ses parties d'angle, des plaques alternées (6) sont entièrement obturées et coopèrent avec des plaques intermédiaires (5) pour définir deux groupes de passages allongés à travers lesquels s'écoulent les fluides d'échange de chaleur respectifs (A, B). Chaque plaque intermédiaire (5) n'est que partiellement obturée et définit avec une des deux plaques (6) adjacentes entièrement obturées une région communiquant directement avec l'atmosphère, l'obturation partielle consistant en des moyens d'obturation (7a, 8a, 9a, 10a) des orifices, interconnectant les paires respectives d'orifices en regard afin de former des canaux à travers lesquels les deux fluides (A, B) s'écoulent sans pénétrer dans ladite région. Les régions forment des chemins à travers lesquels toute fuite de l'un ou de l'autre fluide (A, B) peut s'échapper vers l'atmosphère, empêchant ainsi la contamination d'un fluide par l'autre.

Abstract: The invention relates to a protection device for electrically operated appliances, particularly for appliances used in humid environments, such as domestic appliances for bathrooms, kitchens, cellars, gardens or the like. The protection device consists of an electronic circuit, e.g. having moisture sensors, which responds to conductive fluid penetrating into the appliance housing, and a protection switch (10) which is triggered thereby. In this case, the protection switch is designed as a destructive element (14), especially an explosive element, which directly or indirectly interrupts at least one conductor of the power supply to the appliance being monitored. The advantage of such a switch is an extremely short reaction time. …<IMAGE>…

Abstract: To extract and purify polyunsaturated fatty acids, particularly EPA and DHA, without cis-trans conversion, from naturally occurring oils, such as marine animal oil and various vegetable oils, a mixture of free fatty acids is first extracted from the oil. The resulting mixture of pure fatty acids is then sub­jected to separation by means of urea complexing to remove saturated fatty acids and most mono-unsaturated fatty acids. Remaining solvent and urea are then re­moved from the filtrate which is then subjected to low temperature fractional crystallization in the presence of an organic solvent such as acetone. Substantially pure polyunsaturated fatty acids, especially EPA and DHA, can be separately precipitated by reducing the temperature of the filtrate in two steps. Alternative­ly, the volume of the filtrate is is reduced in two steps and cooled to form precipitates, which are re­moved. The final product is a mixture of substantially pure DHA and EPA.

Dosage errors are determined, with the conveyor (17) shut down or empty, on the basis of the residual filling weight of the storage container (1), and the set values of the individual dosages are corrected by lead values for the next feeding procedure. <IMAGE>

Title: Method for manufacturing a mineral fibre panel.
Inventor: IZARD DAVID GRAHAM
IPC: D21H13/36
Filed: 1988-01-12
Abstract: Method for the manufacture of structural mineral panels on a foraminous support wire (40) forming a dilute aqueous dispersion of mineral fiber and/or lightweight aggregate with some fiber and binder solids in water. A small amount of cationic flocculant such as polyacrylamide is added sufficient to effect coating of the binder solids onto the mineral fiber materials and the slurry is passed to a first flooded section (42) of the support wire (40) to form an open, entangled, structural mass having water in interstitial spaces of the entangled mass. Water is stripped from the mass and the mass dried substantially without collapse of the open structure, first by application of brief pulses of high vacuum (44) followed by further vacuum (46) and passing heated dry air (49) through the open entangled structure. This produces a very uniform homogeneous panel core with very evenly spaced and uniformly sized voids in the open cored structure.

Abstract: The invention relates to a device for tilting a body arranged tiltably on a vehicle, by means of at least one lifting press (2) which can be extended by feeding a hydraulic fluid into a lifting line (12a, 12b).

Abstract: Disclosed is a broadly applicable method for making an article that comprises a superconductive oxide body, including a thin layer on a substrate, or powder particles. In a preferred embodiment, the method comprises forming a precursor melt and contacting at least a part of the melt with oxygen such that the concentration of oxygen in the part of the melt increases to a critical concentration, resulting in formation of the desired oxide, substantially without drop in temperature. The precursor melt comprises at least one metallic element M, and at least the part of the melt is at a temperature T, with T m  < T < T o , where T m  is the freezing temperature of the melt and T o  is the melting temperature of the superconductive oxide. In an exemplary embodiment the melt consists essentially of Yb, Ba, and Cu in 1:2:3 atomic ratio, T is about 900°C. A layer of superconductive oxide on a SrTiO₃ substrate is formed by dipping the hot (900°C) substrate into the melt, exposing the melt-coated substrate to oxygen such that oxygenation and solidification of the coating results, and furnace cooling the coated substrate in oxygen. The thus produced coating has composition YbBa₂Cu₃O 9-δ  (δ ∼ 2.1), is essentially single phase, strongly textured, has T c  of about 85K and J c  of about 3x10⁴ A/cm². An aspect of the invention is the fact that the precursor melt need not be stoichiometric. For instance, we have formed a layer of composition YbBa₂Cu₃O₇ from a melt of composition Yb₂BaCu. The ability to practice the inventive method with non-­stoichiometric precursor melts makes it possible to produce Y-containing bodies (e.g., YBa₂Cu₃O₇ films on a copper substrate). The inventive technique can produce compositionally essentially homogeneous material. It is readily adaptable ro produce ceramics (including high T c  superconductors) and other materials (e.g., AlN) in a variety of shaped (including wire, tape, and powders) by a variety of techniques (including continuous processing). The inventive method can also be used to form a superconductive bond between two pre-existing ceramic superconductive bodies.

Abstract: A latching mechanism used to couple external devices (14) to marine seismic streamer cables (12) is disclosed. The latching device universally couples to collars (18) predominantly used in the seismic industry. A mounting bracket (40) or shank is provided which is coupled to the external device (14). The shank has a lug (66) or finger fixed therein which extends from a mounting surface. Adjacent the lug is a latching device (72) which is comprised of a cylinder having a cam (78) defined at the upper end. The cylinder is recessed within the shank so that the cam (78) and the lug (66) are engaged with an aperture (34) defined in the collars attached to the streamer cable. A lever (82) extends from the cylinder through the exterior of the shank so that an operator may rotate the cylinder, turning the cam (78) in the aperture (34) to a locking position. A spring applies a tensile force to the cylinder, drawing the cam down against the aperature, and pulling the shank tight against the collar. The shank (40) and external device (14) may be uncoupled by simply rotating the lever in the opposite direction which disengages the cam with the aperature, allowing the cam and lug to fall free from the collar. The instant invention provides a device which does not require tools to couple, uncouple or adjust the mechanism. Another advantage is that debris cannot accidentally uncouple the mechanism. Additionally, the design provides a streamline, low noise coupling device.

Abstract: A vehicle having a steerable wheel has a mechanism for retracting the wheel into a compartment in the vehicle. The mechanism comprises a pillar 23 mounted to the vehicle within the compartment at two spaced positions, preferably at the top and bottom of the pillar. A steering arm 26 fixed to the pillar is movable to rotate the pillar 23 about its own axis. A collar 22 is slidably mounted on the pillar 23 but rotatable with the pillar. The collar 22 carries wheel forks 21 on which a pair of wheels is mounted on stub axles. The wheels are turned by rotation of the collar as a result of the steering action on the pillar, and their height is altered by raising and lowering the position of the collar on the pillar. The mechanism is applicable for use in an amphibious craft.
