Patent DE-3040198-A1 (DE)
Inventor: SPORLEDER HEINRICH DIPL ING
IPC: H03K5/26
Filed: 1980-10-24
Abstract: 1. A device for recognising the frequency drift of an oscillatory circuit (G1, T1), using a further oscillatory circuit (G2, T2) to predetermine a reference oscillation (f3), and using a phase comparison circuit connected to the output end of the two oscillatory circuits and which serves to establish the time relationship between the two oscillations (f2, f3), characterised in that the oscillatory circuit (G2, T2) for the reference frequency (f3) produces a frequency which deviates by a factor DELTA f2 from the frequency of the oscillation (f2) to be monitored, and that the phase comparison circuit (T3, K, SW; or U3, MK, SW as the case may be) checks whether and when the two oscillations (f2, f3) - commencing from an arbitrary phase relationship - experience a phase shift of 180 degrees or a whole numbered multiple thereof relative to one another, in that it presets a time window (Z in Fig. 3 and Fig. 4) within which this phase shift is to be expected for the two oscillations, where the phase comparison circuit triggers a message when the two oscillations have not experienced the prescribed phase shift relative to one another in each case after n/DELTA f2 periods of the oscillation (f2) to be monitored.

Title: Spray unit for row cultivations
Inventor: DORFI MICHAEL
IPC: A01G25/09
Filed: 1981-03-27
Abstract: Row cultivations are sprayed from spray nozzles which are moved between the rows and which are supplied with pressurized spray fluid by a pump. For this, the spray nozzles and pump are mounted on a driven spray unit. The operator moves through the rows with the spray unit and is therefore in the spraying range, that is to say is exposed to the effects of the spray fluid. Moreover, such spray units are single-purpose units which can be used only for one purpose and which are not simple to handle on a slope. The object of the invention is to provide a spray unit which is easy to operate and has a simple construction and which can be combined with other units which may be present. For this purpose, there is a platform which is equipped with a travelling drive and on which are arranged the spray nozzles connected by means of a hose to a pump set up in a stationary manner. Furthermore, the platform is connected to a stationary return device by a flexible pulling means and is designed for self-control between adjacent rows. The operator can therefore work from a fixed point and outside the spraying range of the unit. <IMAGE>

Title: Method and apparatus for depositing a continuously conveyed fibre tow into a spinning can
Inventor: LENK ERICH DIPL ING
IPC: B65H54/82
Filed: 1981-04-11
Abstract: For a method for depositing a continuously delivered fibre tow into a spinning can, in which the fibre tow is guided by a thread guide rotating on a horizontal circular path at the tow speed and the tow turns formed, which are circular, as seen in projection, are allowed to fall freely into a round rotating spinning can, it is proposed to deform the tow turns by means of shaping devices, in such a way that elongate curves closed on themselves are formed. Such curves are, for example, symmetrical curves contracted approximately elliptically, ovally or on both sides (Cassini's curves). The advantage in relation to a depositing of circular tow turns is the more uniform depositing of the fibre tow on the depositing surface and the better run-off properties when the fibre tow is extracted from the spinning can. <IMAGE>

Title: Fuel injection nozzle for internal combustion engines
Inventor: FUESSNER PAUL DIPL ING
IPC: F02M61/08
Filed: 1981-10-02
Abstract: A fuel injection nozzle for internal combustion engines is proposed, which has a valve needle (18), preferably opening outwards, which is acted upon by a closing spring (38) and by the fuel pressure counter to this. The closing spring (38) is designed as a torsion spring tube which is displaceable with the valve needle (18) but coupled so that it cannot rotate and constantly exerts a torque on the valve needle. The valve needle (18) is supported in the nozzle body (10) by way of an angled guide (50, 52) which derives from the torque of the torsion spring tube (38) a closing and recovery force acting axially on the valve needle (18). The torsion spring tube (38) has a high work coefficient and a favourable power-to-weight ratio. Owing to the friction produced in the angled guide (50, 52) the reciprocating movements of the valve needle (18) are also damped. In addition the valve needle (18) is simultaneously rotated when lifting off from the valve seat (16) as a result of which the valve seat (16) is automatically cleaned of deposits. <IMAGE>

Title: Photocell and process for producing it
Inventor: HEYES JOSEF DR PHIL
IPC: H01L31/04
Filed: 1982-03-26
Abstract: The invention relates to a photocell whose semiconductor layer is composed of powder which is embedded in conductive material in such a way that the surface to be irradiated with light is exposed. The electrical conductor to be connected to one region of the semiconductor particles is formed by the metal in which the semiconductor particles are embedded, while the other conductor, which is electrically insulated therefrom, is formed by a layer of electrically conductive material in contact with said region. In such a photocell, the electrical resistance is low for the charge carriers liberated during irradiation because the path through the semiconductor material to the electrical conductors is short and the cross-section of the conductors is large. In addition to this advantage in the performance of the photocell, there is a further advantage in its flexibility. <IMAGE>
