Title: Blowing mandrel for extrusion blow-moulding machines
Inventor: FERGER EBERHARD
IPC: B29C49/04
Filed: 1982-08-04
Abstract: The invention relates to a blowing mandrel for extrusion blow-moulding machines, having a mandrel upper part with tubular shank and connections for the feed and removal of cooling water, a calibrating sleeve, a cutting sleeve, a cooling pipe surrounding the shank and the calibrating sleeve at a distance to form a cooling inner jacket on the inside, and a blowing tube leading through the mandrel for feeding the blowing air. The blowing mandrel according to the invention is characterised in that the cutting sleeve is arranged between the shank of the mandrel upper part and the calibrating sleeve and is in direct contact on its inside with the cooling water flowing through the cooling inner jacket. The blowing mandrel according to the invention improves the heat dissipation from the cutting sleeve and thereby permits an increase in the operating rate of the blow-moulding machine. The cutting sleeve can be used on both sides and therefore has, overall, a longer life than cutting sleeves that can be used on only one side.

Patent DE-3241221-A1 (DE)
Inventor: REGENBOGEN KURT
IPC: A63H1/28
Filed: 1982-11-08
Abstract: Die Kreiselsirene als Spielgerät ist ein kompakter Gehäusekreisel mit akustischem Effekt und wird mit Hilfe eines Bandaufzuges aus einem Haltebügel gestartet.  Der akustische Effekt kommt dadurch zustande, daß der innere Rotationskörper zwei rotierende Luftströme erzeugt, die auf die mit kleinen Öffnungen versehene, sich langsamer drehende bzw. stillstehende Gehäusewandung treffen.  Die Kraftübertragung vom Gehäuseschaft, an dem der Bandaufzug wirkt, auf den inneren Rotationskörper erfolgt durch eine Mitnehmervorrichtung im Gehäuse und einer Fliehkraftmechanik im Rotationskörper.  Durch diese mittelbare Kraftübertragung werden größere seitliche Belastungen auf die Lagerpunkte der Rotationsachse während des Aufzugsvorganges vermieden.  Im Haltebügel mit Ver- und Endriegelung wird der Kreiselsirene mittels Bandaufzug ihre Rotationsenergie zugeführt und kann dann mit rotierendem bzw. abgebremstem Gehäuse freigegeben werden.

Patent DE-3307351-A1 (DE)
Title: Pedal drive with a vertical action
Inventor: PRASSO THEODOR
IPC: B62M1/24
Filed: 1983-03-02
Abstract: A foot-operated drive which does not rotate in circles like customary pedal drives but is rather adapted to the anatomy of the legs is characterised in that it converts, perpendicularly and in the direction of the force, the linear movement into rotating movement via two corner gears, the chains being provided with symmetrically arranged pedals and sliding over an asymmetrical work path provided by means of a suitable chain guide, and the two dead-centre points in the working range of the legs being thus avoided. It is also important that the chain transmits the force generated via the foot-operated drive to the wheel pinion via corner gears or deflexion gears. Both chain systems leading via a frame which is adjustable in height <<h>>, in length <<L>> and by the angle << alpha >> and being capable of being fastened in the desired position via a clamping device. The deflexion gears which serve to tension the chain and are fixed after installation. The upper corner gears are force-transmitting and the lower corner gears rotate loosely with them. Both chain systems are guided via the corner gears and their course is thus flush. They are matched to the sizes of the corner gears of the chain guide and to the requirement of the driver. <IMAGE>
Patent DE-3312917-A1 (DE)
Title: Frame table
Inventor: HEINEN NORBERT
IPC: A47B13/04
Filed: 1983-04-11
Abstract: In contrast to the newly developed frame table, all hitherto known table forms have a plane, flush plate which rests on an underframe. They cannot be changed in basic construction. The frame table consists of a frame which can be assembled together and forms the table in combination with push-in bases. Table plate and underframe are no longer separate units. In this arrangement, the push-in bases can be attached at various levels, as a result of which the table plate itself is given planes of different height. In addition, storage cases can also be pushed in at the location of the push-in bases. Furthermore, the shape of the table can also be changed; two or more tables can also be formed depending on the number of frame parts which can be used in the table. These changes in the frame table, which can be carried out with considerable ease, guarantee the greatest possible adaptation and use in home and public furnishings.
