  • Publication number: 20190316745
    Abstract: The invention proposes a lighting device, in particular an emergency lighting device. The lighting device includes a first housing (2), a lighting means (12), for example an LED arranged at the first housing (2) and an electronic circuitry accommodated in the first housing (2) for operating the lighting means (12). A second housing (3) of the lighting device accommodates an energy storage means (13) such as a rechargeable battery, wherein the first housing (2) and the second housing (3) are arranged spaced apart. An interconnecting means (4) mechanically connects the first housing (2) and the second housing (3) in an elastic manner and also connects electrically the electronic circuitry and the energy storage means (13). The interconnecting means (4) of the lighting device of a preferred embodiment comprises a cable which is overmoulded to provide compressive strength in an axial direction of the cable.

  • Publication number: 20190239557
    Abstract: A method of, and equipment for gathering fibres (12) entrained a gas stream, for example by melt blowing, comprises an enclosure (50) having an inlet (57), through which a gas stream carrying entrained fibres (12) may be directed into the enclosure (50), a fibre outlet (58) from which an assembly of gathered fibres (12) may be withdrawn from the enclosure (50) and an exhaust outlet (41) through which gas may pass out of the enclosure (50). The enclosure (50) is constructed to provide a pathway for the fibres (12) from the inlet (57) to the fibre outlet (58) in which surplus gas in the gas stream is separated from the entrained fibres (12) and directed to the exhaust outlet (41), thereby reducing turbulence in the fibres (12) in the enclosure (50) which may affect the quality of the finished assembly.

  • Patent number: 9744283
    Abstract: A peritoneal dialysis system is provided that includes a hardware unit, a disposable unit received by the hardware unit, and a controller. The hardware unit includes a recessed area, a piston having a contact surface, a pneumatic source for supplying a negative pressure, and an actuator configured to move the contact surface of the piston into and out of at least a portion of the recessed area. The disposable unit includes an outer member fitted at least partially within the recessed area of the hardware unit and a moveable membrane positioned between the contact surface of the piston and the outer member when the disposable unit is received by the hardware unit. The controller is configured to cause the pneumatic source to apply the negative pressure to the moveable membrane so as to conform the moveable membrane to a shape of the contact surface of the piston and follow the contact surface when the piston is moved towards and away from the outer member fitted at least partially within the recessed area.

  • Patent number: 8376999
    Abstract: A peritoneal dialysis system includes: a hardware unit including a piston having a contact surface, a pneumatic source for supplying a negative pressure, a stepper motor, a controller including a processor and memory programmed to control the pneumatic source and the stepper motor, and a video monitor operating with a touch screen for sending and receiving information to and from the controller; and a disposable unit including a moveable membrane positioned adjacent to the contact surface, the programmed processor and memory operable to (i) cause the pneumatic source to apply the negative pressure to the membrane so that the negative pressure moves the membrane to conform to a shape of the contact surface and (ii) control the stepper motor so that the membrane follows the piston as the piston is moved away from the disposable unit and moves with the piston as the piston is moved into the disposable unit.

  • Patent number: 7153286
    Abstract: The present invention provides automated peritoneal dialysis systems, methods of operating the systems and devices for performing same. A typical therapy performed by the present invention begins by draining dialysis solution that is already in the patient's peritoneal cavity. The system pumps fresh dialysate from one of a plurality of supply bags, through an in-line heater to the patient's peritoneal cavity. After a dwell period, the spent dialysate in the cavity is pumped out of the patient to a drain or other disposal means. The system then pumps fresh dialysate from the supply bags to the patient and the procedure is repeated as defined in the therapy protocol. The system can pump a last bag of dialysate to the peritoneal cavity for an extended dwell, such as a daytime dwell.
