There may also be copolymerized (d) 0-48% by weight of ethyl, n-propyl, isopropyl or n-butyl acrylate or methyl methacrylate; and (e) 0-25% by weight of 2-ethylhexyl acrylate or methacrylate or a higher alkyl ester such as octyl, decyl, dodecyl or octadecyl acrylate or methacrylate.  Examples of monomer (b) are 2-hydroxyethyl, 2-hydroxy-n-propyl and 6 - hydroxy - n - octyl acrylate, and 2 - hydroxy - n - propyl, 4 - hydroxy - n-hexyl and 6-hydroxy-octyl methacrylate.  Copolymerization is effected by heating the monomers in a solvent such as toluene and preferably in the presence of a polymerization catalyst, e.g. 2,21-azo-bis-isobutyronitrile, benzoyl peroxide or di-tert.-butyl peroxide.  The copolymer may be mixed with a magnetic pigment, e.g. gamma ferric oxide, by ball milling but in a preferred procedure a finely divided magnetic material, e.g. cobalt, is incorporated into the copolymer by reacting the latter with an appropriate carbonyl compound, e.g. [Co(CO4)]2 in toluene.  After admixture with, or incorporation of, the magnetic material, the polymer product can be cross-linked by treatment with an organic isocyanate in the presence, if desired, of an amine or tin-containing curing catalyst. The treated product is then applied to a magnetic tape backing, e.g. polyethylene terephthalate.

Abstract: 1469576 Elevator emergency mechanism HITACHI Ltd 8 Oct 1974 [8 Oct 1973] 43582/74 Heading B8L A system for automatically bringing counterbalanced elevator cage CA to a floor level upon failure of main power supplied to a drive sheave motor M and an electromagnetically disengaged brake MB, comprises a first detector N for detecting electrical power failure, an emergency power supply E, and a second detector for detecting whether an unbalance load imposed on the sheave S is above or below a predetermined value, a supply path from the emergency power supply E to the electromagnetic brake MB being established when power failure is detected and the unbalance load is detected below said value, and being blocked once the cage reaches a normal deceleration starting point on approaching a floor level. With the elevator cage running at normal speed and not in deceleration when a power failure occurs, the cage continues running due to brake release effected by the supply E, until it reaches the normal deceleration starting point for the next floor in the direction of movement, when the brake MB is applied to the elevator in accordance with an elevator speed related signal from a tacho-generator TG passing through a function generator F to a current controller CI. If there is unbalance between the cage and the counterweight, the unbalance moves the cage towards the deceleration starting point for the nearest floor, in the direction determined by the unbalance, the speed of movement during this time being restricted by an on-off sequence of operations of the brake MB being supplied with power from the source E. If the cage is substantially balanced, the brake MB is energized for release, from the source E, before the brake has reacted due to main power failure, whereafter the cage coasts under inertia to the next floor deceleration starting point. If main power failure occurs just as the cage is leaving a floor level, the cage is immediately stopped for the passengers to vacate substantially at that floor level, whereafter the resulting unbalance in the system can be used to move the cage into proper alignment with an appropriate floor.
