Abstract: An apparatus for adjusting the height of a base cabinet having a table top thereon includes a bottom plate supporting a lifting assembly, the lifting assembly including a spindle unit with a spindle and a spindle nut mounted on the bottom plate, an upper end of the spindle unit providing a carrying surface, and a single electric motor for driving the spindle unit.

Abstract: Linear dual actuator for lying or sitting furniture having at least two sections (2,3), which with one end is rotatably embedded in the article of furniture and where each section (2,3) with an arm (5,7) secured to a pivot shaft (4,6) can be adjusted. The dual actuator comprises a housing (8) with a recess (10) in each end for each of the pivot shafts (4,6) on the article of furniture and where the arms (5,7) on the pivot shafts (4,6) after the dual actuator has been mounted on the article of furniture reach into the housing (8). Each end of the housing is furnished with a drive comprising an electric motor (11), which through a transmission (12) drives a spindle (13a) with a thrust element (18) having one end in engagement with the arm (5,7) for 'adjusting the sections (2,3). The electric motors (11) are located axis-aligned with the respective spindles (13a).

Abstract: An electrical actuator system for adjustable furniture, in particular height-adjustable tables (1), comprising at least one linear actuator (4), at least one operating unit (22) and a control box (12). By arranging therein at least one connector for cables into mutually opposing wall sections of the control-box cabinet for connection of linear actuators with cables, great simplification of the connection of the linear actuators to the control box is achieved, as when an uncoupling has been omitted, when the actuators have been wrongly connected during assembly, or if an actuator falls apart.

Abstract: An actuator system having at least one electrical linear actuator, wherein the actuator system comprises a controller and a power supply, wherein the noise reduction of common-mode noise in the input stage to the switch-mode converter is undertaken on the rectified and smoothed supply voltage.

Abstract: An off-mains switch (14) and a control box (15) for electrically adjustable articles of furniture, such as beds, chairs or tables, which automatically interrupt the connection to the power supply when the article of furniture is not adjusted, such that this will not constantly be under the mains voltage. These off-main switches require a multi-part cable which is rigid and thick. In the present structure (14, 15) a single two-part cable (13) is sufficient, as the off-mains switch (14) is configured such that the control signals between control unit/control box (15) and the off-mains switch are transmitted through a mains cable (13). A standard cable having two conductors is then sufficient. This means in turn that standard plugs may be used, and thus that the cable (13) may be connected to the power supply via an ordinary plug. Since, hereby, the off-mains switch may appear as a separate unit, production and logistics are facilitated.

Abstract: An arrangement for height-adjustment, preferably for kitchen tables with base cabinets is designed as a platform comprising a bottom plate (10), on which is mounted a lifting arrangement (13-18) with a carrying surface (11) for an object positioned thereon.

Abstract: By a linear actuator of the type comprising a driven spindle with a spindle nut, the outer positions and possibly also the intermediate positions of the spindle nut can be determined by a specially designed switch construction. This switch comprises an elongated conductor (8a), and next to this at least one other short conductor (8b), and where a connection element (10) for the spindle nut is equipped with an electric conductive element (9), for creating contact between the two conductors (8a, 8b). With two short conductors at the end of the elongated conductor end-stop switches for the nut are achieved and with more short conductors between the two end conductors the position of the spindle nut between its outer positions can be determined.

Abstract: A process for the manufacture of sustained release pellets comprising pelletizing a mixture containing the drug in finely divided form and a binder. The characteristic feature is that:(a) said binder is in particle form consisting of one or more water-insoluble wax-like binder substance(s) with a melting point above 40.degree. C., and(b) said pelletization step is performed by mechanically working said mixture, in a high shear mixer, under the input of a sufficient amount of energy for the binder to melt and pelletization to take place.

Abstract: An automobile cleaning system comprises a source of cleaning fluid and control apparatus connected to the source and responsive to a control input for pressurized output of the cleaning fluid. The system has also a source of pressurized medium, such as positively or negatively (vacuum) pressurized air. A portable unit for issuance of the pressurized cleaning fluid has a first channel with an input port connected to the control apparatus for receipt of the pressurized cleaning fluid and an output port for fluid issuance and has a second channel with an input port connected to the pressurized air source and an output port at a surface of the portable unit for closure upon blockage by a user of the system. A conduit is provided to conduct indication of second channel blockage to the control apparatus as the control input thereto.

Abstract: Apparatus for delivering hot water includes a vessel for releasably containing water and a heat generator compartment in heat transfer relation to the vessel.
