Abstract: A cassette blind with a weighting profile at the lower end of a set of blinds and a blind drive, in which coupling elements with a winding shaft mounted in the cassette profile. Complementary coupling elements with a drive member and complementary coupling elements at a pin which can be stationarily fastened are arranged, wherein coupling elements of the drive member and of the winding shaft mutually engage each other during a rotary movement of the drive member in the winding-up direction of the blinds, and coupling elements of the winding shaft and of the pin mutually engage each other in the opposite direction. The coupling elements at the winding shaft are arranged rotatably over a predetermined angle against spring action in the winding-up direction of the blinds in order to achieve a torsionally elastic tensioning of the weighting profile at the cassette profile at the end of the winding-up movement of the blinds.

Abstract: A respirator with a delivery device, which draws in ambient air via an inlet line and pumps it into an outlet line, with a discharge opening, which branches off from the outlet line and via which a partial flow of the gas being delivered, which can be set with a discharge valve, escapes. Oxygen is added with the smallest possible loss of gas and with good constancy of the concentration by: providing the inlet line with a buffer volume, via which the ambient air drawn in can flow; providing a return line which introduces the partial flow into the buffer volume is present between the discharge opening and the buffer volume; and providing the oxygen source connected to the inlet line and/or to the buffer volume.

Abstract: A multistep spindle drive is provided for converting a rotary movement into a linear movement with different speeds of withdrawal and extension. The spindle drive includes at least two threaded spindles, which telescopically mesh with each other and are in threaded connection with one another, and a nut. The inner threaded spindle is connected to a crank, and the nut is connected to a support wheel via a pipe. The internal threaded connection existing between the threaded spindles has a smaller diameter and a lower pitch than the external threaded connection existing between the outer threaded spindle and the nut. The speeds of withdrawal and extension are changed over based on the greater frictional force. A friction-increasing coupling member is arranged between the threaded spindles. The coupling member is spring-loaded and can be set for changing the friction.

Abstract: A method of aligning a bi-refringent optical fiber with a polarisation sensitive component positioned within a package so that the bi-refrigence axes of the fiber are set in a pre-defined relation to a light guide within the component. The fiber is inserted through an aperture in the package and is approximately aligned with the light guide of the component. An optical probe having a tip provided with an optical polariser is positioned with the tip between the end of the fiber and the component, to collect light from the fiber. The free end of the fiber is manipulated and the output from the probe is monitored until the desired polarisation alignment is achieved whereafter the probe is removed from the package whilst the rotational relationship between the fiber and the component is maintained. Then, the fiber end is moved to optically couple wish the component and the fiber is secured in position. The package may thereafter be completed in the usual way.

A layer having a characteristic foamed structure is formed under the surface layers lying in the gripping area of the user, whereby the thickness ratio between the thicker surface layer and the foamed structure is 1 at the most.

Abstract: In an arrangement of a vehicle auxiliary heater with an integrated regulating device in the region of the floor in the vehicle cab and a control unit remote from the auxiliary heater, e.g. in the region of the dashboard or on an inner wall of the vehicle, it is proposed that the control unit be operationally connected to the regulation device wirelessly via a bidirectional radio link in which use is made of an r.f. unit with a first r.f. module on the operating side with a transmission and reception section and a second r.f. module on the control device side with a second transmission and a reception section. This obviates the need for the complicated laying of prior art wired connections between the control unit and the regulating device of the auxiliary vehicle heater, making the heater particularly suitable for subsequent fitting in commercial vehicles.
