Title: Erase head for magnetic tape - has triple erase gaps to enable high coercivity tape to be handled
Inventor: CHRISTIAN ERNST DR PHIL
IPC: G11B5/127
Filed: 1979-02-20
Abstract: An erase head is designed so that high coercitivity magnetic tape (He = 1000 Oe +) may be erased without variations. The main feature is that three gaps (8, 8', 8") are used. The unit has a winding (3) on a ferrite core (1) that has two proported pole arms (4, 4'). Between the pole ends are located pole insets (2, 2') of a ferromagnetic material. Experimental investigations indicate that optimum performance is obtained when the centre gap (8) is of the order of the 10 times the thickness of the magnetic tape used. With high coercivity magnetic tape with a thickness of 3 um to 4 um, a gap of 30 um is used. Both side gaps are slightly less than the centre gap. A practical design has the pole inserts formed on the tip of a central pole piece.

Title: Adjustable pedal lever abutment, in particular for bicycles
Inventor: DICHTL PETER PAUL
IPC: B62M1/24
Filed: 1981-04-27
Abstract: This invention concerns an abutment (6) which is attached to the bicycle frame (1) or axle (3) by means of an attachment piece (5). This attachment piece (5) has holes (7) whereby adjusting of the abutment (6) is made possible. Since in this invention extremely long pedal levers (4) actuate the wheel drive on both sides of the hub (8) by moving up and down or forwards and backwards, the abutment (6) prevents any overturning of the pedal crank (4) and thus any contact thereof with the ground. To make it possible, when part-way movements are employed in propelling the vehicle, to hold in place or determine the desired length of travel of the pedal crank (4), a bolt or angle (7) is attached to the attachment piece (5) in such a way that the pedal lever path (4) is determined as required, which is of advantage in the case of the physically challenged. <IMAGE>
