[Class 81 (ii).] The denture comprises a rigid plate in which the recess for the gums is lined with material, such as a soft - rubber composition, which is resilient at body temperature but deformable at 212‹ F., or at a temperature within 50‹ F. above, or slightly above, body temperature, so that the lined denture may be moulded on a plaster model of the gums, or in the mouth. A suitable rubber composition comprises 80 parts of purified balata with 20 parts of first latex crÛpe rubber, without sulphur or other vulcanizer. Guttapercha may be used in place of balata, and any clean crepe rubber in place of the first latex crepe. Pigments &c. may be added. In making the denture, a sheet of soft tin or of paper &c. is shaped over the plaster model, and the denture, Fig. 3, is formed on this plate 6 instead of on the model. The plate 6 is tried in the mouth whilst the teeth are in wax. The plate 6 is removed from the denture, leaving an oversized recess for the gums. The recess is coated with cement, the lining material 11, Fig. 5, also coated with cement is pressed in warm, and the denture is placed in the flask 12 which is filled with sand &c. and placed under pressure for 3 or 4 hours. The lined denture is finally heated and moulded on the model and then in the mouth. It may be re:fitted to the mouth after use if there is any change in the contour of the gums. Partial dentures may be made in the same manner. The flask and cover, Fig. 5, are formed with curved fillets 14a, 15a which reduce the volume of sand, direct the flow, and increase the pressure on the denture. The sand is worked down bv rotating the cover of the flask by means of the knobs 15b.

Title: Improvements relating to the production of crimped glass fibres
IPC: D02G1/14
Filed: 1939-08-03
Abstract: 533,032. Making glass fibres. ALGEMEENE KUNSTVEZEL MAATSCHAPPIJ N.V. Aug. 3, 1939, No. 22598. Convention date, Aug. 4, 1938. [Class 56] A method of making crimped glass fibres consists in flowing a stream of molten glass, applying tractive forces successively at intervals along the length and alternatively on each side of the stream, and causing the tractive forces to attenuate the stream and simultaneously crimp the fibres as they are produced. The tractive force is applied by rollers having teeth which intermesh but do not touch one another, so that threads of glass gripped between the teeth are drawn and crimped but are not crushed. The streams of glass flow from a " feeder " 10, Fig. 1, which may be of the kind described in Specification 471,838, and the attenuation of the glass may be assisted by a blower 11 as described in Specification 482,085. The crimping-rollers 13, 14 are driven in unison by a motor 30, and they can be moved to a predetermined vertical position by a rack 24 and pinion 25. The distance between the rolls can be adjusted by a screw 45, and the roll 13 can be held out of operative position by a latch 52. The crimped fibres may be wound on a drum, or collected in a rotating bucket, or deposited as a mat on a travelling support 60. A hood 61 may be used to direct the fibres on to the support and a belt 62 may be used to compress the mat of fibres. For producing fine fibres, the crimping rolls are driven at high speed by two electric motors of the synchronous type supplied with high frequency current. The rolls are mounted in a casing 100, Fig. 6, and air carried around by the rolls passes out through the top of the casing where it is directed on to the glass stream. Oil or other lubricant may be blown into the upper part of the casing, or a lubricant or binder may be directed on to the fibres by a sprayer 120. If the fibres are sufficiently hot before they pass between the rolls, they twist and turn and emerge with crimps lying in different planes, and they tangle and intertwine to produce an integral resilient mat.
