Patent FR-2620886-A1 (FR)
Title: Discriminator of telephone calls
IPC: H04M1/665
Filed: 1987-09-17
Abstract: The invention relates to a system allowing the selection of telephone calls. To this end, the device is installed in series between the telephone line and the telephone. When the sound signal appears, the apparatus goes off hook and begins to listen. If the apparatus recognises the proper succession of programmed voice frequencies, it then rings a sound signal. Otherwise, the apparatus hangs up. In another configuration, the apparatus no longer requires the sending of a code but simply sends an attenuated ringing for a certain time before sounding the telephone itself. In another version of the invention, it will be possible to provide the apparatus for the purposes of recognising the caller. To this end, several codes will be programmed into the apparatus; each code capable of triggering a particular tune. The apparatus consists of a box 1 incorporating a socket 2 for connection to the national telephone network, a socket 3 enabling the telephone 4 to be plugged in, a position selector 5, means for programming the code 6 and a warning sounder 7.

Title: Laundry drier
IPC: D06F57/12
Filed: 1988-02-05
Abstract: The invention relates to laundry driers which comprise an assembly of wire-like laundry carriers, a rigid frame for supporting these laundry carriers in such a way that they are substantially parallel to one another, and suspension means for making it possible to mount this frame on a support, for example an apartment wall, so that it can pivot about an axis relative to this support. In a laundry drier according to the invention, the suspension means 9, 10 are designed so that, when the frame 1 and the laundry carriers 2 are mounted on the support 12, the pivot axis of the frame is substantially vertical and located outside the zone where the laundry carriers are then located. Such a drier makes it possible, in particular, to allow laundry articles arranged on the laundry carriers 2 to drip and dry above a bathtub 3 or a shower and to move the laundry carriers, together with the laundry which they carry, away from this bathtub or this shower if someone wants to use it.
