Title: Solar energy collector absorption panel - mfd. by joining upper and lower plates and providing absorption coating
IPC: F24J2/04
Filed: 1977-07-01
Abstract: The panel is mfd by attaching two plates to each other. To achieve the bond between the two plates, a wire with a m. pt. below that of the metal of either of the two plates is distributed between the faces and the entire panel is then heated to a temp between that of the wire and that of the metal plates. Indented channels in one of the plates provide the flow passages for the heat transfer medium. A coating is applied to the upper side of the panel to increase the absorption of the collector. The plates may be mfd from (stainless) steel or copper. If stainless steel is employed, the absorption increasing layer is obtd by the oxidn of chrome to chrome oxide. The method of joining the two plates together is more economic than existing surfaces. Furthermore, the use of stainless steel enables the outer absorption layer to be achieved reliably and cheaply.
Patent NL-7801986-A (NL)
IPC: C23C14/00
Filed: 1978-02-22
Abstract: A method of producing gold-color coatings on substrates by evaporating a coating material comprising a metallic titanium or zirconium in a housing which has walls which define an evaporation space, comprises, maintaining a vacuum atmosphere containing N2 and argon in the space. The method is carried out using an anode connected to a power source to produce a low voltage arc discharge in the vicinity of the coating material which is arranged within the evaporation space and also maintaining a low voltage arc between the anode and the substrates. A potential difference between the anode and the substrates of a range of between 5 v and 100 v are maintained during the process and, in addition, the electrical potential of the substrates is maintained between 0 and 150 volts lower than the potential of the housing walls which define the evaporation space. The substrate to be coated is coated at a rate of from between 1 to 15 nanometers per second. The N2 and argon atmosphere is maintained so that a partial pressure of the N2-containing component ranges between 2x10-4 and 10-2 millbar. The potential difference between the anode and the substrates is reduced in the course of the process to release the sputtering threshold of the substrate and the housing wall. The partial pressure of the N2-containing components continuously increase in the course of the process.

Patent NL-8501912-A (NL)
IPC: B65G67/02
Filed: 1985-07-04
Abstract: A railroad freight car having a rotatable loading floor for transferring loads between it and a station platform. The railroad station has two platforms on opposite sides of the rail car. An edge of each platform is provided at each longitudinal end with a sloping beam which angles upwardly from the end of the platform towards its center. The lowest part of the beam, which is at the free end of the platform, is below a set of wheels carried on the chassis of the rail car. The center portion of the platform is at a height above that of these rollers. The rollers are arranged to extend laterally of the rail car and to overlie the beams. As the rail car pulls into the station, the rollers will engage the upwardly sloping part of the beams to thereby raise the chassis in relation to its wheels by virtue of extending the suspension as the car continues in its direction of movement. The chassis is, thus, brought into a suitable level to enable the loading floor to freely rotate to overlie the station platform and, thereby, enable the loading and/or unloading operations to take place.

Title: Windmill with vertical axis and vane assemblies on radial spokes - has vanes open and shut automatically
IPC: F03D3/06
Filed: 1988-12-02
Abstract: The windmill vane assemblies are mounted on radial rods (E) which protrude from the hub of the mill rotor. Each assembly has a horizontal bar (C) which carries two pivoting arms (B). The pivoting arms are interlocked by arcs of toothed bearings, in such a way that they move symmetrically and always have the same angle to the horizontal. Mounted on the ends of the arms are flat vanes (A). Mounted on the end of the lower of each pair of vanes is a counterweight (D). When the wind is in one direction, the vanes pivot together, forming a vee-shape to catch the wind. Otherwise, the vanes move to horizontal, parallel positions, where their resistance to the wind is minimal.

Patent NL-9301831-A (NL)
Title: Plastic floor grate for cattle
IPC: A01K1/015
Filed: 1993-10-22
Abstract: The invention relates to grates which are used in sheds for cattle raising. The problem with current grates is that the grate slats are rectangular in cross section, and consequently urine and manure can easily remain on the slats and build up in the gaps between the slats. The object of the invention is to reduce the emission of ammonia. The grate slat is T-shaped with a slightly convex surface, so that the urine and manure rapidly run off. The slats are positioned in a frame which holds the slats in place and, if necessary, increases the load- bearing capacity. In practice, it has been found that the cattle prefer plastic grates to, for example, hardwood grates. Tropical hardwood can no longer be used and is replaced by reprocessed plastic waste, which is therefore also environmentally friendly.

Patent PT-90529-A (PT)
IPC: B65D41/18
Filed: 1989-05-11
Abstract: A container closure (122) comprises a cylindrical molded unitary member defining a top panel (122h) and a skirt depending from the top panel to an open end for securement to the container, the skirt being interiorly tapered (122f) at the open end. The taper begins flush with the outer surface of the skirt (122g) and ends in a first circumference extending radially of the central axis of such cylinder. The skirt further defines a bead (122d) extending radially interiorly of the skirt to a second circumference radially closer to the cylinder central axis than the first circumference. The closure provides sealing retention pressure in accordance with the radially interior extent of the bead and exhibits evidence of an initial removal from the container. In one embodiment, the bead is generally of semispherical configuration and flow passages (122d-1) may exist in the bead, preferably over less than the hemispherical extent thereof. In another embodiment; said skirt further defines front and rear locking tabs (220, 220A, 226) respectively mutually spaced perimetrically at a location above said tapered surface and a bead at a location below said top panel and said locking tabs. The method for making the closures involves the use of a stripper plate (118) to participate in part in defining a mold cavity.
