Patent DE-3141167-A1 (DE)
Title: Loudspeaker arrangement with enclosure
Inventor: RINKOWSKI ALFRED
IPC: H04R1/26
Filed: 1981-10-13
Abstract: 1. The loudspeaker magnet with its frame mounting carries out the low-frequency oscillations of the system in proportion to the diaphragm oscillation. Their interaction lastly determines the resonant frequency of the loudspeaker system. An extension of the area of the magnet and selective radiation extend the frequency range: its oscillating strokes (1/10 mm), which penetrate deeply into infrasound, support not only the loudspeaker diaphragm but also compensate for the enormous losses due to resonance (due to enclosure installation). 2. Counterphases occurring between loudspeaker diaphragm, frame and magnet can be eliminated to only a limited extent, at least diaphragm and magnet oscillations can be acoustically separated and combined again corrected in phase (as required for point 1). The loudspeaker frame is given its own enclosure which has access to the loudspeaker enclosure. The free-standing magnet mechanically drives a relatively large passive diaphragm of the enclosure (drawing VII). 3. Counterphases occur inside and outside a loudspeaker enclosure due to the fact that the rear wall of the enclosure is excited into parallel oscillations. This is avoided by a further loudspeaker/ passive-diaphragm system as at the front but without high-frequency loudspeaker. Two-channel two-way loudspeaker boxes of a new loudspeaker generation are produced electrically isolated with separate frequency filters . <IMAGE>

Title: Lockable closure for the filling connection of a container, especially a fuel tank in motor vehicles
Inventor: WITTWER REINHARD
IPC: B60K15/04
Filed: 1982-03-19
Abstract: In a lockable closure for the filling connection of a container, a filling connection is equipped for bayonet-fastening purposes with a connecting socket which possesses, in addition to a seat surface, radial recesses in the filling orifice and a ramp-like run-on profile inside the connection. The closure itself consists of a cover having a formed-on axial sleeve serving for receiving a closing cylinder, of a sealing ring which is laid round the axial sleeve and which engages on the seat surface, and of its centring piece fitting into the filling orifice and having radial projections which, in the event of coupling, engage into the radial recesses. Underneath the radial projections there are holding bosses which are pressed against the radial projections as a result of axial springing and which are rotationally adjustable between an open position and a closed position in relation to the radial projections fixed in the socket. For easier handling and greater safety, the holding bosses are connected fixedly in terms of rotation to the axial sleeve, so that, together with the cover, they form a rigid constructional unit via the axial sleeve of the latter, the axial springing being arranged between the cover and the centring piece, and the centring piece carrying the sealing ring is movable axially and radially in relation to the constructional unit.
Patent DE-3211526-A1 (DE)
Title: Multiplexible field-effect liquid-crystal display
Inventor: KOHLMUELLER HANS DIPL ING
IPC: G02F1/1365
Filed: 1982-03-29
Abstract: To enable direct-current operation with a high degree of multiplexing in a liquid-crystal display employing a field effect, the following combination of features is proposed: in the liquid-crystal substance, a nonionogenic, reversibly oxidisable and reducible redox system is produced whose oxidation and reduction takes place in a potential range which is within the appropriate potential ranges of the remaining liquid-crystal mixture and also of the electrodes. Said redox system is preferably formed by an electron donor/acceptor component. In addition, each image element of the display is provided with a nonlinear series resistor in the form of a diode. A liquid-crystal display produced in this way is of simple construction, requires little expenditure on circuitry, has an adequate service life and, if commercial Zener diodes are used, permits a multiplex step number of much more than 10<2>. It is suitable, in particular, for twisted cells or "guest-host" displays. <IMAGE>

Patent DE-3230772-A1 (DE)
Title: PLL oscillator circuit for generating different frequencies belonging to a frequency raster
Inventor: POETTER MANFRED DIPL ING
IPC: H03L7/185
Filed: 1982-08-19
Abstract: A PLL oscillator circuit which does not create any selection problems in spite of the use of a mixer arrangement is proposed. The PLL oscillator circuit comprises a reference frequency oscillator (10), the frequency (fQ) of which is divided in a first frequency divider (11) with a fixed divider ratio to the reference frequency (fR). The reference frequency is available at a first input of a phase comparison circuit (14), which is followed by a low-pass filter (15) and a voltage-controlled oscillator (17). The output (18) of the oscillator forms the output of the PLL oscillator circuit and is connected to a second, programmable frequency divider (20). Between the output of the second frequency divider and a second input (40) of the phase comparison circuit (14) there is a mixer arrangement (21) having n mixers (27, 28, 29) and n frequency dividers (30, 31, 32). The last-mentioned frequency dividers each have a divider ratio of 2:1 and are connected in series. The input of the series connection is connected to the output (12) of the first frequency divider, and the outputs (33, 34, 35) of the frequency dividers (30, 31, 32) each lead to a second input (36, 37, 38) of the mixers, which are likewise connected in series and have first inputs (22, 25, 26). The comparison frequency is governed by the condition fv = 2<n>.fT, n corresponding to the number of mixer stages. <IMAGE>

Title: Tension strand for cone pulley belt transmission
Inventor: SCHOPF WALTER
IPC: F16G5/16
Filed: 1982-09-17
Abstract: Elements of this type are used preferably for the transmission of torques from one pair of friction discs in a torque converter to the other. Such designs without links consist essentially of a strip which can be loaded in tension having pressure pieces guided or mounted thereon, whose end sides are frictionally linked to conical friction surfaces. The major disadvantage of conventional designs is the high bending stiffness of the strips and cleat supports, which normally consist of a tension element, combined to form a fixed composite like a belt, or of layered steel strips, and cause high power losses. Furthermore, the mounting and guidance of the cleats is problematic. The main feature of the present tension strand is that it consists of easily bent tension fibres (2,3,4,5,6), preferably of aramide, which are wound, largely individually, continuously or in a specific sequence, around pressure pieces (12) or parts of such pieces and position said pieces thereon such that they transmit power. Said tension fibres can also be embedded in the region of plastically formed pressure pieces. The advantages of said tension strand are: low losses; low specific weight; low noise; economical manufacturing methods; dry running characteristics of some design variations. <IMAGE>
