Title: Closure for vat used for tanning, dyeing etc. - has curved lid running spring loaded on rollers coupled to counterweight
Inventor: DOSE WERNER
IPC: C14C15/00
Filed: 1977-03-07

Title: TV camera aperture control - closes aperture if measured beam current is below normal operating range for tube protection
Inventor: BRAEUER REINHARD DIPL ING
IPC: H04N5/238
Filed: 1977-08-01
Abstract: The control circuit for the aperture setting of a television camera uses a control signal derived from the signal electrode of the camera tube. The circuit ensures that the camera is ready for operation immediately it is switched on, and overexposure leading to possible tube damage is prevented. A circuit (R1, SV, P1) provides a measurement of the beam current of the tube, and is connected to the aperture drive (BA) so that with low beam currents the aperture is closed, and with beam currents of normal operating level the control signal becomes effective in determining the aperture.

A constant resistor and a variable resistor are connected in series. The constant resistor is a nozzle (5) and the variable resistance an annular gap between the nozzle outlet opening and its baffle plate. A plate (2) is provided which becomes elastic due to applied pressure difference. Deformation of this component is transmitted to teh baffle plate (4) so that its distance from the nozzle outlet opening can be varied in relation to the pressure difference.

IPC: C07D303/04
Filed: 1978-08-17
Abstract: Prodn. of bicyclic terpene oxiranes by epoxidation of unsatd. terpene hydrocarbons with peracetic acid/acetic acid mixts. still contg. water, H2O2 and (possibly) small amts. of H2SO4 in the presence of acid binding agents, the epoxidation is carried out in an inert 1-3C aliphatic hydrocarbon, having -CCl3-, -CHCl2-, -CH2Cl-, -CHCl- or -CCL2- gps. The acid binding agent is pref. an alkali (bi)-carbonate used in solid form in an amt. of 0.3-0.7 or 0.6-1.4 mol per mol acid acid content of the peracetic acid mixt.

Hydrolysis of alpha-pinene epoxide gives sobrerol, a therapeutically active substance which can be used in pharmaceutical compositions. Conversion of the terpene is high, and the terpene oxiranes are obtd. in excellent to almost quantitative yield.

Title: Three colour electronic raster scanner - uses digital raster signals to operate laser writing head and thus control projected image
Inventor: BOSSE ROLF DIPL ING DR
IPC: H04N1/405
Filed: 1978-12-04
Abstract: The document is scanned in the three colours by a point-to-point scan and the separate colour densities recorded as a digital signal pattern, after passing through an analoger-to-digital converter. The digital signal allows simple modulation of the pattern for colour correction and serves to control the writing laser projected onto the copy. Different colour densities are simply reproduced by varying the spacing of the raster points so that only one type of point is used. This allows simple control of the writing laser. The screen angle may be varied to minimise the Moiree effect.
