Title: Single or multicore cable with synthetic or rubber insulation - has moisture sensitive tracer which exhibits permanent colour change when exposed to water
Inventor: PATRIKAINEN HANNU
IPC: H01B7/32
Filed: 1980-12-02
Abstract: Along the cable core (1), for example a dry type telephone cable, a tracer thread or strip (9) is included which lies between the core and the outer insulation sheath (2). The tracer incorporates a hygroscopic material, typically a die, which changes its state permanently when affected by the ingress of moisture between core and sheath. The visual indication of the presence, or one time presence, of moisture is confined to the linear extent of the moisture penetration. The affected length can thus be established visually enabling the minimum amount of cable to be cut out and thereby avoiding waste. The hygroscopic material can be incorporated in the tracer used for cable identification, or in the binding ( for individual conductor groups. It can be a material which, when wet spreads over and colours a considerable area of the affected length.
Patent DE-3101110-A1 (DE)
Title: House/room heating with a heat pump in the monovalent mode
Inventor: WILHELM VONHOFF JUERGEN
IPC: F24D3/12
Filed: 1981-01-15
Abstract: In conventional high-temperature heating (90-70 DEG C), the heat is transferred via radiators/convectors to the room to be heated. If such a system is to be changed over to a heat-pump mode (60-40 DEG C), the dimensions of the radiators have to be increased considerably, but the corresponding space for this is normally unavailable. However, even for floor heating which would be appropriate, in old buildings the disadvantages are considerable. The existing building is unsuitable for the installation or the costs are too high. Consequently, according to the invention, the installation of radiant ceiling heating, which works in parallel with the existing radiator heating, is provided. The radiant ceiling heating and the radiator heating are coordinated with one another in such a way that unpleasant draught phenomena occurring in radiant ceiling heating near the windows are eliminated by the radiator heating under the windows. Comfort in a room can be adjusted individually by regulating the two heat sources (radiant ceiling heating/radiator heating) relative to one another.

Filed: 1981-02-19
Abstract: The device for compensating for undesirable changes in length on spindle drives can be used in all equipment and machines in which a spindle imparts an exactly defined movement to a sub-assembly under different temperatures. With minimum cost, the intention is to achieve precise elimination of the temperature effect over the entire spindle length in proportion to the distance of a nut from the fixed bearing of the spindle. To this end, a lever is pivotably arranged on the fixed bearing. The lever is orientated parallel to the spindle in the zero position. The nut is connected to the lever in an articulated manner via a driver. The lever is pivoted in accordance with the temperature effect by a plunger which is displaced in a passage of an expansion chamber.

Title: Disturbance warning device for a sewing machine
Inventor: TAKIGUCHI MICHITAKA
IPC: G08B21/00
Filed: 1981-05-16
Abstract: The occurrence of such disturbances or states deviating from the nominal state, in which the stitch forming devices are prevented from generating a desired stitch pattern, is determined by a number of detectors arranged in the sewing machine, each of the number of detector devices generating a detector signal in accordance with the state determined. In a storage device, a number of groups of speech data are permanently stored and each of these groups is predetermined in such a manner that it vocally reproduces one of the states deviating from the nominal state. A selection device selects one of the number of groups in accordance with the detector signal and, on the basis of the group selected, an electrical signal is generated on the basis of which an electroacoustic device arranged in the sewing machine pronounces one of the states deviating from the nominal state.
