Abstract: 484,411. Imbibition printing films. BROOKES, N. E. (Technicolor Motion Picture Corporation) Nov. 4, 1936, No. 30040. [Class 98 (ii)] Gelatin film blanks for imbibition printing are prepared by treating the blank in a solution of a hardening agent, the pH of the film and of the hardening bath being previously adjusted to produce a pH value corresponding to the isoelectric point of the gelatin during the hardening process. The film may be subsequently washed in a bath maintained at the isoelectric point. The process may be used for films for imbibition printing in colours, on which a sound track has been formed in developed silver. For example, the sound track is developed in a non-hardening metol developer, the film is washed in water at a pH of 7, fixed in neutral hypo solution and again washed in water at a pH of 7. It is then hardened in a solution of chrome alum of 50-52À5 gms. per litre having a pH value adjusted to 3À45 by addition of ammonia and again washed.

[Also in Division H1] Electrically driven apparatus such as a razor, coffee mill, mixer &c. for use on two voltages is automatically adapted for use on the higher voltage by a change-over switch operated by the magnetic attraction of the stator. Fig. 1 shows an oscillating motor having a pair of stator poles 3, 4 with a switch arm 13 pivoted to the pole 3 at one end and having its other end normally urged away from the pole 4 by a spring 18 on a switch 16, e.g. a microswitch. In the position of the arm, switch 16 connects two sections of the exciting winding 1 in parallel for use on the lower of the two voltages but as soon as the apparatus is connected to the higher voltage, the increased attraction of pole 4 pulls the arm 13 into engagement with a stop 12 and actuates the switch 16 to connect the winding sections in series. After the change-over, the attraction of pole 4 is sufficient to maintain the arm in engagement with the stop 12 until the apparatus is switched off. Fig. 5 shows another embodiment in which the motor has a rotary armature 24 and the arm 13 is pivoted on a frame part 25 attached to the pole 3 and the switch 16 is carried by another frame part 26 on the pole 4. The switch in this case comprises a leaf spring carrying a contact 28 movable between two fixed contacts, the leaf spring providing the bias for arm 13.
