Title: Improvements in and relating to sound records
IPC: G11B3/70
Filed: 1931-10-30
Abstract: Condensation products are manufactured by condensing polyvinyl alcohols with aldehydes in the presence of acids or substances having an acidic reaction.  In an example polyvinyl alcohol is dissolved in ice-cooled alcohol and condensed with aqueous acetaldehyde in the presence of sulphuric acid.  The product after stirring with cooling for 6 hours is neutralized with caustic soda and the excess aldehyde and alcohol are steam-distilled.ALSO:Flexible unbreakable sound records are made from polyvinyl alcohol-aldehyde condensation products.  In an example of such a condensation product, 100 parts of polyvinyl alcohol are introduced into an ice-cooled mixture of 750 parts of alcohol, 25 parts of sulphuric acid and 200 parts of 50 per cent aqueous acetaldehyde.  This is stirred while cooling, becoming highly viscous, and after neutralization of the sulphuric acid with caustic soda, the excess acetaldehyde and alcohol are steam blown out.  The product is then repeatedly washed with water and dried in vacuo.  A high-boiling plastification agent is preferably added and the records are moulded under heat and pressure.  Thus, for example, 90 kilograms of polyvinyl-aldehyde condensation product are gelatinized at 80 DEG  C. with 10 kilograms of p-toluene sulphamide and 60 litres of alcohol and 30 litres of benzine, and the mixture is further worked up as in the case of celluloid.

[Also in Group XX] In an optical multiplexer which comprises a plurality of field lenses and which serves for the selective establishment of an optical path from any one of a plurality of image sources to a single television camera, the said field lenses are so disposed that the centres of some at least of said lenses lie approximately in a first plane containing the axis of said camera while the centres of others of said lenses lie in at least one further plane also containing the axis of said camera, and a revoluble mirror is arranged to effect deflection of said optical path from one to the other of said planes. As shown, the optical mutiplexer includes a rotatable mirror 9 and two pivoted mirrors 7, 8 whereby selection can be made of any one of six optical paths proceeding from a 16 mm. film projector 1, a 35 mm. film projector 2, two slide projectors 3, 4 and, two episcopic devices 5, 6 to a single television camera 11. Field lenses 10 are disposed in each of these light paths. The mirror 9 is rotatable by a handle 12, through any multiple of 90 degrees into positions in which it is secured against accidental rotation by a locating device. As shown in Fig. 2, this mirror 9 may be mounted on a shaft 16, rotatable by the handle 12 and having a collar with marginal notches 17 for co-operation with a spring loaded locating device. In one of the indexed positions, a contact 18a of the switch 18 connects with a contact 18c of the switch through a contact plate 19 insulated from the shaft 16. Closure of these contacts energises a relay, not shown. This relay may invert the polarity of the vertical deflection currents supplying the deflector coils of the pick-up tube of the camera 11 and effect corresponding alterations to the circuits providing the spurious signal compensating voltage and the circuits controlling the vertical position of the raster. When the mirror is turned into its other operating positions further switches 21, 22 and 23 operate to supply current to a further relay by means' of which, for example, there may be effected an alteration of the target bias.
