An electrical radiator, particularly for fan-forced heaters, is provided which includes a resistance heating element disposed on an insulating element connected to the housing of the fan-forced heater. The coil winding of the resistance heating element is secured to the insulating element by means of clamping elements and is freely extending therefrom. A bimetallic switch in series with the resistance heating element serves as a heat protective switch and is disposed on a connector bar connected to the insulating element and carrying the electrical connectors for the coil winding. One end of the coil winding is secured on one side of the bar to a first bracket remote from the insulating element and which is rigid with the bar and connected to a first connector. The other end of the coil winding is secured to a second bracket disposed on the other side of the bar near the insulating element and which is rigid with the bar. The bimetallic switch is disposed on a side of the connector bar which faces that end of the coil winding which is, on one hand, connected to the insulating element and, on the other hand, is secured to the first bracket remote from the insulating element, so as to obtain exactly defined protective circuits.

An arrangement for connecting corresponding edge areas of thin-walled bodies together wherein each edge area is provided with bending sections and empty sections alternately disposed to each other with respect to the corresponding bending and empty sections of the other edge area. The bending sections of the other edge area are disposed through the corresponding empty sections of the edge area whereby the bending sections collectively define a common channel through which an elongate connecting member is inserted to secure the bodies together.

An air humidifier has an electric fan unit arranged in a housing for delivering a through-flow of air between feed-air and discharge-air openings in the housing; at least one filter device for the through-flow of air; and a device for releasing liquid to the through-flow of air. A first housing component accommodates the fan unit with filter strips and feed-air and discharge-air openings. A second housing component is a vessel for storing liquid. The two housing components form autonomous structural units which can be fixed to and detached from one another. It is possible for the first housing component to be utilized as a separate unit independently of the second housing component.
摘要:
A system for connecting corresponding edge areas of adjacent thin-walled bodies. Each edge area is provided with at least one bent notch portion which engages a corresponding bent notch portion carried by the other edge area, such that apertures provided in the notched portions are coaxially aligned to receive a common connecting member for securing the bodies together. A plurality of such notch portions may be spaced along the lengths of the corresponding edge areas to define a series of coaxial apertures through which an elongate connecting member is inserted for securing the bodies together.

Disclosed is a humidifier with an electrical ventilating unit arranged in a housing for supplying an air throughput stream between air inlets and air outlets in the housing, at least one filtering device for the air throughput stream, and a device feeding fluid to the air throughput stream. Humidifying the air throughput stream is optional by providing two autonomous, attachable or detachable housing components (2, 3), the first of which (2) can be used independently of the second one (3) as a separate unit. Said first housing component is provided with a ventilating unit (4), filtering devices (6, 8), and air inlets (9) and outlets (10), and said second housing component (3) is configured as a recipient for storing fluids.

A rotary switch for insertion in switch panel openings includes a housing (1), knob (3), a detent body (2) for limiting the knob position in the housing, a variable position coupling (7), a switch controlling cam member (8) and spring contact switches (13) retained in fixed position in the housing. Switch followers (12') engage the cams (12) of the cam member (8) to operate the switches in predetermined sequence and modes that can be varied by varying the cam arrangement on the inner and outer surface of the cam member. The switch program can also be varied by varying the relative angular position of the knob relative to the cam member through the variable position coupling.
