Title: Seat, in particular motor-vehicle seat
Inventor: MORISHITA ISAO
IPC: B60N2/70
Filed: 1986-12-29
Abstract: A seat, in particular for a motor vehicle, has a seat frame, a main seat spring in zig-zag form and coiled auxiliary seat springs which are arranged between the seat frame and the main seat spring, the seat spring arrangement being formed at a relatively large clear height with respect to the constructional height of the seat, between the surface of the seat spring arrangement and the seat frame and being deformed by pressure to the design or constructional height. In this manner, the seat can essentially compensate for the spring constant of the seat spring arrangement, even in the case of a low loading as someone sits down on the seat or in the case of a high loading as the person leaves the seat, with a relatively simple construction and without changing the basic construction so that the performance in respect of the comfort when travelling is improved.

Title: Pharmaceutical preparations
Inventor: PARADIES HENRICH H PROF DR MED
IPC: C09K23/18
Filed: 1987-08-06
Abstract: A pharmaceutical preparation is disclosed which is constructed either from unilamellar or multilamellar vesicles or from a micelle, consisting for both geometric forms of a cationic surfactant having a monovalent anion and an antiviral pharmaceutical active ingredient directed against reverse transcriptase, dispersed in a solvent whose pH is between pH 7.0 and 8.0, the critical micelle concentration (CMC) - even for the vesicular forms - being in the range from 1.0 x 10<-7> to 1.5 x 10<-5> mol/litre. The preparations disclosed in particular have the advantage that the antiviral active ingredients can cross quantitatively (passively) into the cytoplasm after dissolution of the inhibited membranes by the N<+> surfactants (vesicular structure). They therefore make possible, among other things, long-term therapy in the case of the ARC or AIDS complex.
Patent DE-3727053-A1 (DE)
Title: Electronic multiplier
Inventor: WINDSHEIMER KLAUS DIPL ING
IPC: G06G7/161
Filed: 1987-08-13
Abstract: In conventional electronic multipliers, long-term drift and temperature drift of the integrating capacitor affect the measuring accuracy. It is the object of the invention to make the multiplier insensitive to long-term drift and temperature drift of the integrating capacitor. Additionally, the number of electronic components is to be reduced. A signal proportional to a first input variable is fed to the electronic multiplier, which works according to the time-division method, at a first input of an integrator (2). A square-wave reference signal from a pulse generator (10) is additionally fed to this input via a resistor (8). The integrator (2) integrates the square-wave reference signal, by means of which this is simultaneously used as a triangular wave generator. The second input of the integrator (2) is connected to a reference potential. The output signal of the integrator (2) is led to a first input of a comparator (3), the second input of which is connected to the reference potential. A signal, the pulse-space difference of which is proportional to the first input variable, appears at the output of the comparator. With this signal a switch (6) is activated, via which a signal proportional to a second input variable is fed to a resistor (7). The time-average of the voltage at the resistor (7) is proportional to the product of the first and second input variables. <IMAGE>

Patent DE-3732596-A1 (DE)
Title: Plastic dowel
Inventor: FISCHER ARTHUR PROF DR
IPC: F16B13/06
Filed: 1987-09-28
Abstract: As fastening elements, which can be introduced into bores of a masonry structure, use is made of plastic dowels which have legs which can expand to a great extent in the region of cavities. In this arrangement, the shaft part located at the end of the dowel is drawn in the direction of the dowel head by means of the fastening screw which has been introduced. In order to obtain a guiding aid on the introduction of the fastening screw, there are arranged, along the longitudinal bore of the dowel, preferably a plurality of screw guides in the form of flash, which mechanically connect the mutually opposite legs before expansion. When the legs expand in the cavities, said screw guides rupture and thus do not hinder the expansion procedure.

Abstract: An aircraft (1) includes a radar reflector (2) arranged so that the radar signature of the combination of aircraft (1) and reflector (2) is different from that of the aircraft (1) alone. This confuses enemy radar either by removing or folding flat the reflector (2) when on a combat mission so that the aircraft (1) on its own has to the enemy a surprisingly low radar cross- section; or, alternatively by making the radar signature of the combination correspond to that of an aircraft of a potential enemy.
