Title: Oscillator circuit with an oscillating crystal
Inventor: JANSSEN GERT DR ING
IPC: H03B5/32
Filed: 1981-05-11
Abstract: The invention relates to an oscillator with an oscillating crystal which is connected in series with a resistor which is small in comparison with the series resonant impedance. The series circuit is located in a feedback-type oscillator circuit and is driven by a low-impedance voltage source. The voltage picked up across the resistor is supplied to the transfer element following in the oscillator circuit. A controllable attenuator in the oscillator circuit is also included in an amplitude control loop. In addition, the oscillator circuit contains an electronically controllable phase rotator, with the aid of which the oscillator frequency can be pulled. This results in a relatively large pulling range with high spectral purity of the output signal.

Title: Protective canopy for cars and camper vans
Inventor: RIEDEL SIEGFRIED
IPC: E04H6/02
Filed: 1981-08-18
Abstract: The protective canopy for cars and camper vans serves to avoid damage and to protect against the effects of the weather on cars and camper vans and requires a smaller installation area than do conventional garages. For simpler production and mounting, the protective canopy is produced from a plurality of parts, prefabricated from lightweight, rupture-resistant material, and screwed together. The very simple and reliable opening and closing operation of the protective canopy is effected by two gas-pressure lifting mechanisms. It is secured by a closing device. The possibility of application for cars and camper vans of different widths and lengths is achieved by simple adjustment of the guide rails for the track width of the vehicles. Owing to the rounded-off form of the protective canopy - see drawing, Figures 1, 2 and 3, position 1 - there is no risk of injury. Due its simple anchoring method (precast concrete foundations), the protective canopy can be easily erected. It should be further emphasised that expensive, complex mechanics and hydraulics for the actuation of the protective canopy are completely dispensed with; functioning is ensured in all weather conditions. <IMAGE>

Title: Dirt deflector for motor vehicles
Inventor: BUTZ EUGEN OTTO
IPC: B62D25/18
Filed: 1981-09-15
Abstract: The invention relates to a dirt deflector (10a) for motor vehicles, with an attachment bead (11a) which is matched to the contour of a mudguard cutout, is composed of elastically flexible material and has an attachment groove (13). By means of this groove, the attachment bead can be pushed onto a flange (16), projecting towards the interior of the mudguard, of an angled mudguard fold (14) limiting the mudguard cutout, and can be attached to the mudguard (15) by means of at least one attachment element (124). Known dirt deflectors are disadvantageous because their screw attachment elements require additional holes in the flange of the mudguard fold which make installation more difficult. The invention achieves the object of providing a dirt deflector which can be installed in a particularly simple, secure manner and does not require any additional vehicle-body attachment holes, as follows: with its groove bottom (23) extending parallel to the flange (16), the attachment groove (13) is of U-shaped design and is bounded on the inside of the mudguard by a support web covering the outside of the flange narrow side (38) and on the outside of the mudguard by an abutment rib (22) pointing away from the mudguard cutout. The flange (16) can be wedged into the groove bottom (23) via at least one attachment element (124) and via a clamping attachment part (20) connected to the attachment bead (11a). <IMAGE>

Patent DE-3202740-A1 (DE)
Title: Front wheel suspension for motor bikes
Inventor: DEPREE MANFRED
IPC: B60G15/00
Filed: 1982-01-28
Abstract: Modern motor bikes have high breaking decelerations (up to 9.5 m/sec<2>) and have comfortable suspensions, that is to say large spring paths with a low spring constant. The resulting severe dipping of the customary telescopic fork due to displacement of the axle load onto the front axle during braking brings about a change in the vehicle geometry. In order to counteract this, in previous solutions which have already been used by the motor bike industry for some time, the through-flow cross-section of the throttle in the damper elements is reduced during braking and thus the damping forces increased. In the present invention, as an alternative the spring force of the spring damper system is increased during the braking process. This can be achieved by means of different, suitable devices by increasing the spring constant (c) and/or the spring path (f). This permits the vehicle geometry to be maintained irrespective of the duration of the braking process.
Patent DE-3206561-A1 (DE)
Title: 3-D rotary toy
Inventor: LIEKE MICHAEL
IPC: A63F9/08
Filed: 1982-02-24
Abstract: 3-D rotary toys, consisting of rotary bodies which can be rotated in relation to one another about axes of rotation and which, fastened on guide bodies, are held and guided in guide rails (corresponding to Fig. 45b: FS = guide rail, FK = guide body, DK = rotary body, IK = inner sphere). These guide rails intersect; at the intersections, the rotary bodies of one path of rotation can be transferred into another path of rotation. The inner body is spherical. In it, the guide rails are preferably designed as cutouts, in which the guide bodies are held and guided. The rotary bodies are all geometrical bodies: cubo-octahedra, spheres, octahedra, hexakisoctahedra, tetrakisoctahedra, icosahedra etc. The rotary bodies can be designed as spherical shell bodies and, in the case of onionskin-shaped arrangement, made extensively transparent. On rotating the outer shell about given axes of rotation, the rotary bodies of the inner shell(s) are rotated in their paths of rotation or - according to position - not rotated. The outer shell can also be formed by the geometrical bodies described above. The whole arrangement of the rotary bodies which can be rotated in relation to one another represents an intelligence toy. As a result of the onionskin-shaped arrangement with extensive transparency of the outer shell(s), the degree of difficulty for refinding a previously clearly marked position and combination of the rotary bodies in relation to one another after multiple previous rotation is increased. <IMAGE>

Title: Device for laying and at the same time filling a fabric casing used in hydraulic engineering with heavy, free-flowing materials or material mixtures such as mortar, sand or the like
IPC: E02D15/10
Filed: 1982-03-04
Abstract: The invention relates to a device for laying fabric casings of large volume to be filled with heavy, free-flowing materials or material mixtures such as mortar, sand-water mixtures or the like, with a folding magazine for the empty fabric casing, at least one filling tube leading into the fabric-casing part drawn off in each case from the folding magazine, and a covered retaining means for the fabric casing to be drawn off from the folding magazine, which retaining means is arranged behind the folding magazine in the laying direction of the fabric casing. So that higher retaining forces can be produced, provision is made according to the invention for the retaining means to be a deflecting device arranged in the fabric-casing draw-off path running from the folding magazine to the depositing and laying location. This results in the advantage that tensile forces in the fabric casing can be resolved into several components at the deflecting elements of the deflecting device, which components act in different directions according to the degree of deflection. The force component continuing in the fabric casing ultimately as a pure tensile force can here become so small that in the ideal case it is neutralized by the oppositely acting friction between fabric casing and the surface of the deflecting element.

Title: Process and apparatus for determining the exchange state of an ion exchanger
Inventor: NAUJOKS REINHARD
IPC: B01J49/85
Filed: 1982-03-30
Abstract: The invention concerns small ion exchanger plants which are fitted with exchanger cartridges. Such plants cannot be economically monitored, and discharge of unpurified or badly purified waste water therefore often occurs due to the exhaustion of the exchanger cartridge. To prevent this, it is proposed according to the invention to insert a beam balance (4) on which the exchanger cartridges (2,3) are installed on both sides, so that the exhausted exchanger cartridge becomes evident by sinking, or this sinking can be used to give a signal or to shut off the feed. <IMAGE>

Title: Digital filter circuit with a second-order transfer function
Inventor: LUEDER ERNST PROF DR ING
IPC: H03H17/04
Filed: 1982-04-07
Abstract: The invention relates to a digital filter circuit with a second-order transfer function (H(z)), using two delay sections (unit-delay sections A, B), adders and digital shift circuits (V gamma ) for shifting the data word by a predeterminable number of places (bits). The invention has the object of specifying those circuits in which only sums or differences occur in the individual multiplier coefficients. This object is achieved by the input line (xo) being followed by a first input adder (1) and the output line (yo) being preceded by an output adder (O) and a shift circuit (Vo) being located therebetween, by the entire circuit being constructed as a recursive (D') circuit structure (C) and being subdivided into four substructures (I, II, III, IV) extending in parallel with respect to their topological arrangement, in the first (I) of which the shift circuit (Vo) is located, and by the two delay sections (A, B) and further adders (2, 3, 4) and further shift circuits (V1 to V11) being arranged in the individual substructures (I, II, III, IV) in such a manner that the coefficients (a gamma , b gamma ), to be allocated to the transfer function (H(z)), can be essentially represented by sums and differences of the shift circuits (V gamma ). <IMAGE>

Patent DE-3230223-A1 (DE)
Title: Method for operating a circuit arrangement with two MOS field-effect transistors series-connected to a voltage source, and monitoring circuit for carrying out the method
Inventor: BRAJDER ANTONIO
IPC: H02M7/5387
Filed: 1982-08-13
Abstract: In the method according to the invention, the voltage present at the drain-source path of each MOS field-effect transistor (1-4) is monitored by means of a monitoring circuit. Each MOS field-effect transistor receives a drive pulse when the voltage present across it is reversely directed. A reverse current which would otherwise flow through the diode (1a-4a) integrated in each MOS field-effect transistor is thus conducted via the drain-source path of the MOS field-effect transistor. This prevents a storage charge from being built up in the diode which would lead to high reverse currents on reversal of the voltage present across the MOS field-effect transistor. <IMAGE>
