[Also in Division G4] A method of tabulating a platen, type-carrier or the like to any position in a line from any other comprises a device which compares a new tabulating position as represented by a binary or similar code with the old tabulating position and decides the direction of the movement of the drive mechanism to move the platen &c. to the new position. The new position is determined by the operation of electromagnets M 0 , M 1 , M 2  &c. one of which is situated in each possible tabulation position together with parallel operated relays R 0 , R 1 , R 2  &c. These relays, in turn operate a relay R 10  having a contact r 10  in the platen, or type-carrier, operating circuit. A further relay R 11  having openable contacts r 11  in the electromagnet circuits M 0 , M 1 , M 2  &c. is operated when R 10  is operated. These contacts r 11  can open the input lines so that no further signals can be fed in. At the same time the direction of rotation of the motor which drives the platen &c. is determined by means of change-over contacts D 1 , D 2  associated with the mechanical attachments to the electromagnets, Fig. 1 (not shown). The motor is stopped when the electrical contacts operated by the electromagnets M 0 , M 1 , M 2  &c. compares with contacts A 0 , A 1 , A 2  &c. operated when the platen &c. reaches the determined platen &c. position, Fig. 2 (not shown).

Filed: 1927-02-01
Abstract: 289,564. Carpmael, W., (I. G. Farbenindustrie Akt.-Ges.). Feb. 1, 1927. Triarylmethane dyestuffs are produced by joint oxidation in alkaline solution of a p-methylated aromatic oxycompound such as p-oxydiarylmethane or the corresponding hydrol and an oxyaromatic compound. In an example methylenedio-cresotinic acid and 2-oxynaphthalene-3 : 6-disulphonic acid are oxidized by means of air in the presence of an oxygen carrier such as copper sulphate. The resulting dyestuff dyes wool with after chroming a reddish-blue shade. Instead of methylenedi-o-cresotinic acid other p-oxydiarylmethanes may be used, such as methylenedi-ocresol, methylenedisalicylic acid, p-monooxydiphenyl methane, 4<1>-diethylamino-3-methyl-4-oxy- 5-carboxydiphenylmethane or 4<1>-oxy-3<1>-carboxynaphthyl - 3 - methyl - 4 - oxy-5-carboxyphenylmethane or hydrols thereof. Instead of 2-naphthol : 6-disulphonic acid other sulphonic acids and also carboxylic acids of 2-naphthol may be used. Phenols, alpha- and #-naphthol, polyoxynaphthols and polyoxyphenols may be used. According to a further example, p-cresotinic acid and ocresotinic acid are oxidized jointly whereby a dyestuff dyeing wool with after-chroming a reddish violet shade is obtained. p-Cresol or its derivatives may replace the p-cresotinic acid and instead of o-cresotinic acid, phenol, cresols, or their derivatives, oxyaromatic acids or mixtures thereof, for example a mixture of o-cresotinic acid and 2-oxy-3-naphthoic acid may be used. 4<1> - Oxy - 3<1> - carboxynaphthyl-3-methyl-4-oxy- 5-carboxyphenylmethane is obtained by condensation of o-cresotinic acid, alpha-oxynaphthoic acid and formaldehyde.

In an energy converter according to the parent Specification in which a capacitor having a dielectric whose permittity changes with temperature is charged at a low temperature and high capacity and then discharged through a load after heating the dielectric to cause a decrease in capacity and a consequent increase in stored charge. The initial charge on the capacitor is provided either by radiation-sensitive devices or by poling the capacitor, i.e. by heating the capacitor to a temperature above the Curie point then cooling to below the Curie point while maintaining a potential across the capacitor, then removing the potential and shorting out the capacitor to remove excess charges. If after poling a capacitor in this way it is heated again to above the Curie point bound charges are released and transformed to charges free to flow as an electric current. Fig. 2 shows a modification of the circuit described with reference to Fig. 4 in the parent Specification in which the initial charge in the capacitor la is provided by " poling " or by radiation-sensitive devices and in which the flow of current from the capacitor after the heating cycle is controlled by the time constant of the capacitive inductive circuit rather than the Zener diode as disclosed in the parent Specification, the time constant of the circuit being related to the heating cycle time so that charge only flows from the capacitor when the capacitor is at its maximum energy condition. Fig. 4 shows a modification of the A.C. generator described with reference to Fig. 12 in the parent Specification using a transformer to serve as an inductive load offsetting the phase shifts introduced by the converting elements C1 and C2 and having a feedback arrangement including the transformer and diode 205 which replenishes the dissipated charges, utilizing energy stored in the magnetic field of the primary winding.
