Filed: 1984-03-23
Abstract: The hearing aid, in particular a behind-the-ear hearing aid (1, 2) comprises:
 a first unit (1) comprising an amplifier (4), a part- the hook (3) - formed with a duct (16) and a space (8),
 a second unit (2) comprising an electro-acoustic transducer (12), which second unit is intended to be worn in the ear,
 A tubular element (15) for the mechanical connection of the two units (1, and 2, respectively), which tubular element accommodates connecting means (14) for electrically coupling the transducer (12) to (an output of) the amplifier (4). 
<??>The duct (16) has such a diameter that, if the element (15) has not been secured inside the hook (3), the element (15) is axially slidable inside the duct (16). This enables the hearing aid to be adapted to the size of the ear of the person wearing the hearing aid. The connecting means (14) have such a length that even in the case of adaptation of the hearing aid to a big ear the electrical connection is still in tact or can be made. When the hearing aid is adapted to a smaller ear, the connecting means (14) are in fact too long. The space (8) is intended for taking up the excess length of the connecting means (14).

When two detection systems are employed it is also possible to measure the surface roughness.
Patent NL-8600890-A (NL)
IPC: G11C19/28
Filed: 1986-04-09
Abstract: The invention relates to a CCD having a so-called diode cut-off input, in which the input diode is applied to a reference voltage and the input signal is supplied to the input gate located in front of the first clock electrode. More particularly if the electrodes are composed of a transfer part and a storage part with incorporated potential difference, it is possible that, when charge is transported from the input gate to the first clock electrode, a large amount of charge is left behind. In order to avoid this and/or to be able to enlarge the dynamic range of the input signal, a MOST switch controlled by the same clock voltage as the first clock electrode is arranged between the input gate and a reference voltage, for example earth. This switch becomes conducting when the charge is transferred, as a result of which the potential level below the input gate can be adjusted above the surface potential below the transfer part of the first clock electrode.

Patent NL-9201920-A (NL)
Title: Method for the preservation of wood
IPC: B27K5/00
Filed: 1992-11-03
Abstract: The invention relates to a method for the preservation of wood by the removal of loose material, such as insects, larvae, bore dust and rotten wood from wood affected by insects and/or fungi, with the wood being caused to vibrate. Because of the vibration, part of the loose material present in the affected wood leaves the wood via exit apertures, boreholes, cracks and other openings. The interior of the wood is thus more readily accessible to pesticides, synthetic resins, etc. The aforesaid method can be combined with the boring of holes into the wood before causing it to vibrate, as a result of which the method according to the invention becomes more effective because there are more openings through which the loose material can leave the wood.
