Abstract: A pulse valve arrangement includes a valve housing on which is fixed a control valve The valve housing includes a circular cylindrical portion with a valve member movably arranged therein. The valve chamber has an inlet adapted to be connected to a pressure medium source for allowing pressure medium to flow into the valve chamber and an outlet through which pressure medium flows out of the valve chamber. The control valve may be closed in which the outlet of the valve chamber is moved to a closing position blocking the flow of pressure medium, or may be opened in which the outlet of the valve chamber is moved to an opening position allowing a pulse of pressure medium therethrough. The valve member within the valve housing is freely displaceable within the circular cylindrical portion of the valve housing based on the pressure within the valve chamber as controlled by the control valve.

Abstract: The present disclosure relates to a fabric filter system, which may be used for removing particulate matter from a gas, such as a combustion process gas. The filter system includes a fabric filter (3) which is placed in a filter compartment. From the filter, gas flows via a filter plenary space (5) to an outlet duct (7), where the gas exits. A flow control device controls the amount of air exiting through the outlet duct. The flow control device comprises a louver-type damper (17). This provides reliable and efficient control of the gas flow. A collar (21), connecting the plenary space (5) with the outlet duct (7), improves the gas flow into the duct.

Abstract: A method, system and device for communication establishes communications sessions between otherwise incompatible communication networks. A central unit is used to facilitate communication systems between objects, by referring to a database of communication attributes associated with different communication networks used by a calling part and a called party. Rather than have direct connections from one communication network to a next communication network, and having unique translators to support such direct connections, each of the communications is directed to a central facility, that identifies common protocols that are supported by the different communication networks to be employed when establishing a communication session between a first communication network and a second communication network.

Abstract: The invention relates to processing an electronic payment cheque that relates to a transfer of an amount of money from an account of a first user in a first banking institute to an account of a second user in a second banking institute, which processing includes generating digital signatures by means of asymmetric encryption. The method comprises the following steps:•in a first SIM card, creating an electronic payment cheque and signing the electronic payment cheque with a first signature;•transmitting the signed electronic payment cheque to a second SIM card in a second mobile equipment of the second user;•in the second SIM card, additionally signing the electronic payment cheque with a second signature;•transmitting the thus signed electronic payment cheque to subsequently initiate a deposit of the amount of money in the electronic payment cheque into the account of the second user.

Abstract: An arrangement for controlling microbial content or growth in a fluid, comprising a) a zeolite with micro-pores charged with an agent having affinity to the zeolite micro-pores and having antiseptic properties and b) the fluid, the zeolite and the fluid being enclosed by, at least partially in contact, or being arranged for being brought at least partially in contact. The fluid contains molecules being larger than the micro-pores of the zeolite and having less affinity, as defined, to the zeolite than the agent. The fluid may contain a therapeutically active compound or composition in a therapeutically effective amount and concentration and that the total amount of agent in the zeolite is larger than an amount corresponding to an antiseptic level for the fluid. Also disclosed are methods, uses and zeolites for control of microbial content or growth in a fluid.

Abstract: A new use of hydrophobic zeolites, viz. for removing preservatives from (poly)peptide solutions, e.g. solutions of pharmaceutical preparations. The use is of particular interest in connection with protein solutions, especially insulin solutions. The invention further relates to an injection syringe for such solutions, in which syringe a zeolite of the type at issue is placed for contact with the solution to remove preservatives therefrom.

Abstract: A lifting device comprising a tube (A) sealed at both ends or a pipe similarly closed at both ends. Both tube (A) and pipe are compressible in the axial direction. By regulating the vacuum in the space defined by the tube (A) or pipe, the length of the tube or pipe can be regulated, thus raising or lowering goods connected to the tube (A) or pipe. An arrangement is provided to permit rotation of the tube in relation to its support, and to act as a vacuum check valve.
