Title: Catapult with a curved butterfly and pivot pin
Inventor: WEBER MICHAEL
IPC: A63H27/14
Filed: 1981-01-29
Abstract: The invention relates to a catapult in the form of a plane clamp having a rail, which is suitable for catapulting an inserted flying toy in the form of butterflies or the like (boomerang, flying saucers) by thumb pressure and for setting these flying objects in rolling movements. The curve is critical for the rolling flight of the butterfly. Flying objects without a curve remain in a flat orbit during flight. The catapulting is based on a variation in the angle of the inserted flying object and therefore of the formed-on pin by means of an appropriate pressure intensity. By means of manually variable pressure intensities, it is possible to determine both the direction of flight and the flying distance.

Title: Fireplace with a waste gas flap lying in the waste gas path, and a ventilation flap coupled to the waste gas flap
Inventor: KUTZNER LUITPOLD DIPL ING
IPC: F23L11/00
Filed: 1981-03-03
Abstract: A fireplace is equipped with a waste gas flap lying in the waste gas path, and with a ventilation opening, having a ventilation flap, connected into the waste gas path downstream of the waste gas flap in the direction of flow. There is a time relationship between the closure of the waste gas flap and the opening of the ventilation flap, and vice versa. For this purpose, a mechanical coupling is provided. In the extreme open position of the waste gas flap, a signal emitter is activated and delivers a release signal for starting-up of the fireplace. In order to ensure that the ventilation flap is closed tight for the operation of the fireplace, the ventilation flap bears in its closed position against a closure limit stop; included in the coupling between the waste gas flap and the ventilation flap is an elastic transmission member, such that, after the ventilation flap has come to bear on the closure limit stop, the waste gas flap can still be adjusted further in the direction of its extreme open position. <IMAGE>

Title: Brake indicator lights (green)
Inventor: REINTJES HORST
IPC: B60Q1/26
Filed: 1981-04-22
Abstract: The field of application of the invention is intended to be at the front right-hand side and left-hand side of a car; yellow flashing light on the outside, green brake light on the inside, for the visual indication of the braking process. The advantage lies in indicating to other road users that the vehicle is being braked; predominantly to reduce the risk of accidents for pedestrians and cyclists and to increase the flow of traffic and consequently also to save fuel and produce fewer exhaust gases. The technical problems are to be solved in the following way: each car has yellow flashing lights at the front right-hand side and at the left-hand side. The reflectors are to be changed, instead of one lamp there are now two lamps, instead of a yellow lens there is now a green-yellow lens (two-coloured glass), green for brake indicator lights and yellow for flashing lights and as an additional fourth function these are to be connected to the operating lever of the flashing light system (see drawing). By virtue of the design, green lamps can be mounted in addition to the conventional flashing lights. <IMAGE>

Title: Portable speaking machine for people with impaired speech
Inventor: GUTWENIGER OTTO
IPC: G09B5/06
Filed: 1981-04-22
Abstract: The invention relates to a speaking machine which makes speech possible by the press of a button calling up from audio-tape cassettes not only sounds and consonants of a language but for the most part syllables, and by consequently achieving a comprehensible reproduction of speech. Since comprehensibility and speaking speed depend essentially on the number of stored syllables, 108 syllables have been provided, which along with the consonants and sounds resulted in 144 buttons, which are undoubtedly necessary for the German language. In the drawing, Fig. 1 shows how it is made possible to call up the desired syllable or sound from the audio tape immediately by pressing a button. If the button (7) is pressed, the first of four sound tracks of the four-track sound head (5) is connected. Further pressing moves the button link (2) and presses the pinch roller (8) onto the magnetic tape (20) and the running capstan (12) moves the magnetic tape (20) forwards, after which the sound head (5) presses onto the magnetic tape and the stud (4) pushes onto the cassette (1) and switches on the amplifier and loudspeaker. If the button is no longer pressed, the spring (11) takes the link into the starting position and the magnetic tape automatically rewinds. <IMAGE>

Title: Electronic time announcing unit
Inventor: FRIEDRICH GUENTHER
IPC: G04G13/00
Filed: 1981-06-09
Abstract: The time announcing unit at airports makes it possible for the police, fire brigade, DRK (German Red Cross), etc. to put onto the magnetic tape a time reference which can, without any auxiliary device, be recorded and remonitored, since it does not operate with any sort of code. The currently marketed, very expensive announcing or time-coding systems can be replaced by this unit with substantially lower costs. In addition, it is possible thereby to dispense with the expensive dedicated (leased) Post Office lines in favour of one's own time announcing units, which lines are used inter alia for these purposes. For the rest, the accuracy of a time announcing unit according to Claims 2, 4 and 5 cannot be achieved by any other clock or control unit; it amounts to 1 x 10<-13> per week.

Title: Stranding apparatus for stranding machines, especially pretwisting and drawing-off apparatus
Inventor: PREUSSNER THEODOR
IPC: D07B3/10
Filed: 1982-03-13
Abstract: In such an apparatus having a rotor carrier frame and a drawing-off disc mounted transversely to its axis of rotation, the effects of the gyroscopic and centrifugal forces on the rotor carrier frame are to be very largely avoided. For this, a rotational element (13) driven to rotate in the opposite direction is mounted on the rotary axle (12) of the drawing-off disc (10). The shape, dimensions, masses and/or rotational speeds of the drawing-off disc (10) and rotational element (13) and of the co-rotating constructional elements (26, 25, 14, 27, 28; 34, 33, 15, 35, 36) are selected so that the respective product of the mass moment of inertia and angular speed of the constructional units rotating relative towards one another is at least approximately equal. The drawing-off disc (10) and rotational element (13) are respectively mounted via a hollow shaft (28, 36) on the common rotary axle (12). The hollow shafts (28, 36) are supported (31, 32; 38, 39), in a manner mounted rotatably on the rotary axle (12), against the centrifugal forces directed to the rotor carrier frame (1). The product of the total mass of the constructional elements (25, 26, 14, 27, 28, 31, 32, 12, 24) assigned to the drawing-off disc (10) and the distance between their common centre of gravity and the longitudinal axis of the rotor carrier frame (1) is at least approximately equal to the product of the total mass of the constructional elements (33, 34, 15, 35, 36, 38, 39, 24, 12) assigned to the rotational element (13) and the distance between their common centre of gravity and the longitudinal axis of the rotor carrier frame (1). <IMAGE>
