Abstract: 1,101,883. Measuring position electrically. DRUCKMASCHINENWERK PLANETA VEB. Feb. 8, 1966, No. 5446/66. Heading G1N. The positions of the edges of each of a succession of sheets passing, for example, through a printing press, are measured while it is momentarily at rest by means of inductive sensors 1, 2,  3, Fig. 1, which supply their outputs via a selector switch 4 to an amplifier 5 and indicator 7, the circuit including means for averaging the signals obtained from any one sensor for a predetermined plurality of successive sheets. A unit 8 synchronized with the press ensures that measurements are made only when a sheet is at rest. The sensing units (1, 2, 3, Fig. 2 not shown) alternatively may have individual amplifiers (5/1, 5/2, 5/3) and individual averaging circuits each comprising capacitors (9, 11), a diode (10), and smoothing RC circuits (12, 13), with associated indicators (7). Associated with each sensor circuit there also may be provided a threshold switch (16/1, 16/2, 16/3) with an associated adjusting means (15/1, 15/2, 15/3) in order to provide a common storage unit (17) and indicator (18) with a signal when a given positional tolerance for a sheet or sheets is exceeded. A set of sensing units as described may be associated with each of a succession of presses in a colour printing process, each set having a respective indicator, or being switchable to a common indicator (18).

Title: Improvements in or relating to magnetisable iron oxides
Inventor: SOBY WILLIAM
IPC: C01G49/02
Filed: 1954-02-27
Abstract: Improved magnetizable ferrosoferric or gamma ferric oxides, suitable for magnetic recording tapes, are prepared from finely divided iron oxide which has been subjected to partial chemical dissolution.  The particle size, shape and distribution characteristics of the magnetic oxide, which are dependent on those of the starting oxide, must be such that the particles can be magnetically orientated on the recording tape and to this end, the initial iron oxide should exhibit an overall degree of shape anisotropy.  Acicular alpha ferric oxide is preferred and this may be subjected to partial dissolution with hydrochloric or sulphuric acid or ferric chloride solution, and thereafter converted in known manner to the magnetic oxide desired. According to an example, finely divided alpha ferric oxide in hydrated or anhydrous state is treated with 20 per cent hydrochloric acid solution containing a wetting agent at 80 DEG  C. for an hour, filtered, washed and dried.  Alternatively, a 20 per cent aqueous solution of ferric chloride is employed.  The partially dissolved alpha ferric oxide may then be treated in accordance with Specification 765,464, by precipitating ferrous oxalate thereon and heating to 400 DEG  C. in a neutral atmosphere to obtain ferroso-ferric oxide.  This may be oxidized to gamma ferric oxide by heating in air at 200 DEG  C.  Alternatively, the partially dissolved oxide may be heated at 400 DEG  C. in hydrogen and steam to form ferrosoferric oxide which can be oxidized to gamma ferric oxide as before.
