Abstract: A light beam projector has a light source and a reflector arranged to have light generated by the light source converge into a light beam. The reflector has a hollow curved surface with a focal point where the light source is positioned, and a filter able to change the color of the light beam based on the angle of incidence of the beam on the filter. The filter has a plurality of filter elements arranged by sectors to form a diaphragm between the light source and the light beam outlet from the projector. In order to change the angle of incidence of the light beam on the filter elements, the sectors are able to rotate on their axes from a closed position, in which they fully intercept the light beam, to an open position, in which they do not intercept the light beam, as well as to all intermediate positions. The light beam projector has at least two filtering systems, one including at least one of the diaphragms, placed one after the other along the path of the light beam.

Abstract: Dispensing device of washing agents for a dishwashing machine, of the type comprises a body (2) to be fastened to a surface or wall delimiting a washing tub, having at least a portion of said body (2) protruding inside the washing tub; said dispenser (1) has at least a tank (11) for containing a liquid washing agent, means for dosing and/or dispensing a dose of liquid washing agent, a filling port (10) through which the liquid washing agent can be introduced into the tank (11), and closing means (15) of the filling port (10). According to the invention, the closing means (15) are capable of at least two different operating positions, where in one position they are apt to receive the liquid washing agent and direct it or convey it to the filling port (10), in order to fill the tank (11).

Abstract: A sheath is provided with a stationary deflector disposed on the path of the slider so that contact between the slider and the deflector causes the slider to be inclined and consequently causes the needle to be inclined inside the sheath. A return mechanism is provided so as to push the inclined slider back in the opposite direction so that the point of the inclined need is prevented from moving. This disposition ensures that the needle cannot escape from the sheath after it has been used.

Abstract: A centralized device for supply voltage control of a load with power factor correction condensers for lighting engineering applications has an array converter for obtaining a portion of power, with a plurality of switches located between the network sinusoidal supply and the load. The centralized device has controlling and regulating means for managing both the activation and deactivation states of the switches of the array converter so as to avoid sudden voltage changes across the load and provide for control of the load voltage.

Abstract: A fluid connector, for use in the medical field, has a tubular male socket and a tubular female socket. Each socket includes a fitting end for an end piece and a nesting end. The female socket has external notches for axially retaining a locking collar which is fixed on the male socket by penetration of lugs into ports on the collar.

Abstract: A telecommunications network for mobile users of the third generation has a user subsystem and a transport subsystem, associated with an access subsystem, which has a general user-access communication interface and a transport-access communication interface facing them, respectively, able to ensure information flow between the subsystems. The user subsystems can connect to the access subsystem through telecommunications cables.

Abstract: A method and apparatus for transferring/receiving audio and/or video signals for bridging synchronous and asynchronous networks and minimizing delay time over such networks including analysing the active network interface for determining the network interface that is receiving and/or sending data, taking a multiplexed synchronous-clock signal from the network and providing it to a bitstream analyser, analysing the format of a multiplexed signal obtained from another audio codec, analysing the audio format, adapting the ISDN network clock to the IP network clock for forming a clock-adapted digital signal, encoding the digital signal, adapting the encoded signal to IP datagrams, and, inserting the datagram signal in the IP network.

Abstract: A telecommunications network for mobile phone users comprising a user subsystem and a transport subsystem associated by means of an access subsystem, which connect to them respectively through a user access communication interface and a transport access communication interface suitable to allow the exchange of data flows between said subsystems, the access subsystem identifying a coverage area of the telecommunication network for mobile users characterized in that said access subsystem determines on the territory a separated cellular coverage for the transmission from the user subsystem to the network with respect to that from the network to the user subsystem, said access subsystem STA) being composed from, in addition to bidirectional base stations, as known, also from stations suitable to support monodirectional transmission in uplink or in downlink.

Abstract: A cock has an indexable rotating key. Indexing is achieved by a raised element on a shaped base of a housing of a barrel, and a ring which is formed at the end of the key and which is elastically deformable in a transverse plane. The raised element and ring form stubs and notches which cooperate to determine key blocking positions when the key is being rotated. The cock is suitable for use with medical instruments.

Abstract: A device is described, for dispensing washing agents for a household washing machine, in particular a dishwasher, said dispenser (1) having at least a space (3B) for containing an amount of washing agent necessary for performing a washing cycle, wherein the charging of said amount of washing agent in said space (3B) is performed manually and the dispensing of the washing agent is performed at least partially by gravity. According to the invention, the device comprises at least a dispensing body (3) capable of performing angular or rotary movements around a first axis and angular movements with respect to a second axis.

Abstract: In a lantern detachable cap, a clip part having a shape of circle is provided at a lower end of the extension portion formed at the connecting portion of the moving manipulate member, and a lantern is attached to and detached from the clip, the lantern has a shape of cylinder, a battery is loaded within the lantern, and an on/off switch is protruded from one side of the lantern. In addition, the clip part may comprise a pair of clips and be formed at the lower end of the extension portion of the moving manipulate member. According to the lantern detachable cap, since the lantern detachable cap has a clip part at a lower portion of a connecting portion of a moving manipulate member and a lantern attached to and detached from the clip part, the lantern can be freely attached and detached. In addition, since the detaching/attaching mechanisms of the lantern are simplified, production cost can be reduced.

Abstract: A device for dispensing washing agents is described, for a household washing machine, in particular a dishwasher, said dispenser having at least a tank for a liquid washing agent and an arrangement for dispensing a dose of said washing agent.
