A wiring appliance (18) e.g. a switch includes projections (22a, 22b) extending from its side. An attachment plate has an aperture for receiving the appliance (18) including upper abutment studs (13), a downwardly extending portion having a ledge (12) for engaging beneath the projection (22a) of the appliance and a downwardly projecting leg plate (14). The leg plate (14) is elastically deformable ...

An attachment device for a wiring appliance which is adapted to be located on the reverse side of a plate of the attachment device which is formed of molded plastics and has an aperture therein for receiving the appliance (23). The attachment device comprises a support (17), the lower end of which is able to be elastically deformed outwardly of the aperture, an engagement projection (18) provided ...

This invention is directed to tetrahydronaphthalene and indane compounds and processes thereto. These compounds are useful as tumor inhibiting agents, in the treatment of neoplasms and dermatological conditions.

A control circuit is configured to detect by an active filter white noise levels in detection outputs from an intermediate frequency amplifier in an FM stereo demodulation circuit so as to control the separation of outputs from the stereo demodulation circuit into left and right stereo channels, responsively to the white noise level, and is characterized in provision of a current detection circuit...

The present invention is directed to a dip tube and valve with a quick-disconnect coupling for use in combination with a collapsible bag to dispense a liquid product therefrom. The dip tube is extruded or otherwise formed from plastic or other suitable materials and includes at least one channel in the peripheral surface thereof extending along the entire length of the dip tube. As a vacuum or suc...

In an inertial system for sensing the angular rotation and translational motion of a structure utilizing a pair of accelerometers in a back-to-back arrangement vibrating substantially linearly along an axis normal to their force sensing axes, a mechanism utilizing a parallelogram structure is used to impart the vibratory motion to the accelerometers.

The game has a casing (1) which encloses counters (5,6), some of which have one colour, while the others are coloured differently. By position alteration, the counters are caused to move between a container (2) inside the casing (1) and a position where the form varying patterns with different colour structures. Such patterns can be observed through transparent parts of the casing.

In a sensor for indication of current heat demand inside a building and its various parts, the sensor consists of a housing divided in two chambers (3, 4) by a partition, whereby the partition is kept at a pre-determined temperature, for example 20 degrees. An additional temperature sensor (5, 6) is positioned in each chamber (3, 4) to detect the temperature of the air in that chamber, whereby the...

The panel (13) for at acoustic system is formed from fibre material and is covered on both sides by surface layers (14). The panel can be oscillated in a direction perpendicular to its major plane, for generating or damping sound travelling in the surrounding air. - The central part of the panel can be provided with e.g. surface stabilising layers of an air permeability greater than that of the re...

The seal is provided between screw-shaped surfaces on drive and running screws (1,2) which rotatably engage with each other in a screw pump. At least one (a) of the screw-form surfaces is lined with softer material than that for the screws. - The screws are rotated in their installation position, with superfluous material being worn off from the surfaces until they fit tightly against one another....
