Title: Method and apparatus for transporting viscous material
Inventor: TAMPER JUHA
IPC: F04C2/107
Filed: 2013-12-04
Granted: 2021-02-09
Abstract: Apparatus and method for transporting nanofibrillar cellulose in the form of viscous liquid dispersion. The nanofibrillar cellulose is unloaded from a container (3) through a discharge point (3b) which is the lowermost point with respect to the volume of nanofibrillar cellulose in the container at least at the time of unloading and is transported to a target location along a pipe (2) using a progress- sive cavity pump (P2). The discharge of the nanofibrillar cellulose is ensured by selecting the distance (L) of the suction side of the pump (P2) from the discharge point (3b) so short that the nanofibrillar cellulose flows from the container (3) by the effect of the pump suction, or pressurizing the nanofibrillar cellulose in the container (3) to such a pressure (p) that it will flow at the selected distance (L) of the suction side from the discharge point by the common effect of the pressure of the nanofibrillar cellulose and the pump suction.

Abstract: A security element (9) for a security document (10) comprises a first, second, third and fourth line grid (R1, R2, R3, R4) which contrasts in each case with the substrate surface (0) and is assigned in each case to a pattern (M1, M2, M3, M4) comprising an embossed structure (P1, P2, P3, P4) of the substrate (9). A first, second, third and fourth pattern angle (phi1, phi2, phi3, phi4) differ from one another. A first security information item (I1) is coded as a localized distribution of the first and the second pattern (R1, R2), and a second security information item (I2) is coded as a localized distribution of the third and the fourth pattern (R3, R4). The first and the second security information item overlap here. By way of an arrangement of the first and the second pattern (R1, R2) in first grid cells (RZ1) and by way of an arrangement of the third and the fourth pattern (R3, R4) in second grid cells (RZ2), and by way of an alternating arrangement of the first and second grid cells, specific intensity distributions which can be used for examining the authenticity result from different viewing directions (A, B, C, D) of the security document.

Abstract: Examples of a pressure wave generator configured to generate high energy pressure waves in a medium are disclosed. The pressure wave generator can include a sabot carrying a piston. The sabot can further comprise a locking means to lock the piston in a fixed position when the locking means are activated. When the locking means are in a deactivated position, the piston can be released and can move at least partially away from the sabot. The sabot carrying the piston can be disposed within an inner bore of a housing of the pressure wave generator and can move within the inner bore of the housing from its first end toward its second end along a longitudinal axis of the bore. A transducer can be accommodated in the second end of the housing. The transducer can be coupled to the medium and can convert a portion of the kinetic energy of the piston into a pressure wave in the medium upon impact of the piston with the transducer. The sabot carrying the piston can be accelerated by applying a motive force to the sabot. Once accelerated within the inner bore of the housing the sabot can be decelerated by applying a restraining force to the sabot while the piston can be released at least partially from the sabot to continue to move toward the transducer until it impacts the transducer. Examples of methods of operating the pressure wave generator are disclosed.

Title: Variable transmission window system
Inventor: ASH KEVIN L
IPC: B60J3/04
Filed: 2007-06-11
Granted: 2020-12-15
Abstract: An electrical control system is disclosed for controlling a variable transmittance window. The electrical control system comprises a slave window control circuit coupled to the variable transmittance window and a user input mechanism for supplying control signals representing desired transmittance levels for the variable transmittance window to the slave window control circuit. The slave window control circuit controls the transmittance of the variable transmission window in response to control signals from the user input mechanism. The user input mechanism includes lights which provide information, such as current state and/or selected state of the variable transmittance window, whether the variable transmittance window is currently changing states, whether the user input mechanism is being overridden, and whether the system is operating properly. By providing such user feedback through the lights, user experience is much less complicated when attempting to control the transmittance of the variable transmittance window.
