Patent NL-90051-C (NL)
IPC: C08J3/02
Abstract: Polymers containing at least 80 per cent of acrylonitrile are dissolved in aqueous nitric acid of 46 to 68 per cent by weight concentration at temperatures below 80 DEG  C., and the solutions produced are processed at temperatures up to 180 DEG  C. into shaped structures such as films and fibres.  In a modification the acrylonitrile polymer is dissolved in a mixture containing 15 to 95 per cent of nitric acid and 85 to 5 per cent of nitromethane. Polymers of acrylonitrile specified are polyacrylonitrile and copolymers with vinyl pyrrole, vinyl chloride, vinyl acetate, styrene, butadiene, methacrylonitrile, and acrylic and methacrylic acids.  The process is preferably applied to polymers having a molecular weight between 10,000 and 90,000 which have been prepared with the assistance of organic catalysts.  The methods by which the solutions are prepared may be varied according to the temperatures and concentrations of nitric acid employed; when using a mixture of nitric acid and nitromethane the polymer is preferably first suspended in nitromethane and the suspension converted to a solution by the addition of nitric acid.  Reference has been directed by the Comptroller to Specification 701,652.

Abstract: 1450427 Spring door closers with fluid damping G K N-STENMAN AB 12 Dec 1973 [21 Dec 1972] 57685/73 Heading E2M [Also in Division F2] A spring door closer, of the type in which door shaft 4 provided with a pinion 3 drives a piston 6 within a fluid filled cylinder 5 against a closer spring 9 and a fluid channel 11 links both sides of the piston, is provided with means located in the channel which constricts fluid flow during an initial section of the door closing movement but which widens this constriction during the final portion of the door opening movement. As shown an adjustable valve spindle 13 has a conical end portion 13a which engages in a seat 14a in a slidable sleeve 14 biassed toward the spindle by a spring 16. When the door is opened the piston moves to the left from the door closed position shown in Fig. 1 expelling fluid firstly via channels 11c, lid then, as the piston covers lid, through 11c alone. In this final stage the fluid forces sleeve 14 to the right to widen the constriction between 13a and 14a (Fig. 4). For the first portion of the closing movement i.e. before the piston uncovers channel 11d fluid is drawn into the cylinder through channel 11c forcing the sleeve 14 to the left to narrow this constriction. The slow movement of fluid through this narrowed constriction delays the closing of the door until channel lid is uncovered and provides an alternative passage for the fluid. Final damping of the door occurs as the piston covers exit passage 11a and fluid must flow through a passage 11b regulated by screw 12. A plate 24 resting against a washer 23 provides a safety valve to relieve pressure should the door be closed too quickly, though this may be replaced by a ball valve (Figs. 5-8 not shown). Fig. 9 shows a modification of the constriction means in which the spring 16 acts on a check valve 25 which seats into the sleeve 14 and has a slot 27 for the restricted passage of fluid in its closed position. This check valve provides overload protection during the opening of the door, enabling a larger fluid flow to pass.

Abstract: The required heat is generated by an electric arc. The heat generated by the electric arc is conducted through at least a portion of the connection piece (4) and caused to melt a brazing metal (5) provided between the connection piece and the metal surface (7). The heat conducting portion of the connection piece (4) prevents direct contact between the electric arc and the metal surface (7) and the brazing metal during melting thereby preventing disadvantageous thermal actuation of the metal surface (7). When the current to the electric arc has been disconnected, a mechanical force is applied to the heat conducting portion of the connection piece (4) pressing the latter against the metal surface (7). A portion of the brazing metal (5) underneath is thereby pressed out under the remaining joint-forming surfaces of the connection piece also.

Abstract: A self-locking panel assembly for use as ceiling panels comprising a plurality of panel units. Each panel unit is formed out of one or more panel elements and a rail extending across the panel elements. The rail is formed out of a lower section and an upper section that are offset from each other such that at one end of the unit the lower section forms a tongue sticking out, and at the opposite end, the upper section, in combination with the panel element, forms a slot dimensioned to receive the tongue. The ends of the rail are complementary and nonlinear such that they fit together. The panel units of this invention are installed in place. The rail of a first panel locks in place with the rail and panel element of the adjacent panel. The edges of the adjacent panels are thus restricted from movement so as to limit the individual free movement of separate panels.

Filed: 1992-10-16
Granted: 1999-09-21
Abstract: ABSTRACT     Control systems are described that permit access to certain buildings or rooms only to authorized persons.     The control systems comprise data carriers (transponders), which are carried by these persons and brought into local proximity to a reading device, so that the data of the data carrier can be transmitted wireless to the reading device.  The reading device transmits the authorization data received into a central evaluating unit, where said authorization data are checked.  If the authorization data correspond with the check data, the evaluating unit causes the release of a door, so that the authorized person can enter a room.  Only the data carrier is programmed with the customer-specific authorization data, whereas the associated reading devices are initially unprogrammed.  The reading devices are programmed in due course by the data carrier, which, for said purpose, contains, in addition to the authorization data, corresponding control data.  The latter are transmitted to the reading device as well.  In this way, costly programming of the reading devices can be dispensed with.

Abstract: Wind-driven electric generator apparatus has a generator head supported on a tower for free-yaw movement and for free-pitch movement within predetermined limits.  The generator head has a downwind rotor with a pair of elongated blades mounted on a hub that is rigidly attached to a rotor shaft driving an electric generator.  The blades are flexible and have a coning angle therebetween that varies with wind velocity.  The generator head is capable of aligning itself with the wind direction azimuthally and elevationally. A yaw brake prevents an excessive yaw rate.  In a most preferred embodiment, pitch movement and yaw movement beyond small angular ranges are regulated, and an electrohydraulic yaw drive system corrects gross azimuthal misalignment with respect to the wind direction.

Granted: 2001-07-24
Abstract: A method and system for determining the minimum number of rearrangements for connecting an input gate to an output gate through a rearrangeably blocked communications matrix represent the communications matrix by a square matrix having a first dimension that represents the input stage switches of the communication matrix, and a second dimension that represents the output stage switches of the communications matrix, and wherein the square matrix has cells each representing an intersection of the first dimension with the second dimension and indicating a possible center stage switch connection through of the communications matrix. The method and system identify a blocked center stage switch of the communications matrix in terms of the first dimension and the second dimension and identify a pair of center stage switches, where one of which does not have the same output stage switch as the blocked center stage switch, and the other of which does not have the same input stage switch as the blocked center stage switch. In parallel, the number of rearrangement steps necessary for a rearrangement sequence through the communications matrix that uses the first center stage switch and, then, the number of rearrangement steps for a rearrangement sequence that uses the other center stage switch are determined. The method and system terminate these number determining functions upon first determining the rearrangement sequence requiring the smaller number of rearrangement steps.
