[Also in Group XI] A smooth seam is produced between two thermoplastic sheets, or an existing seam is smoothed, by means of a pair of smooth flat high-frequency electrodes which press the material at the seam to a thickness substantially equal to that of a single sheet of the material, the operative face of at least one of the electrodes having a covering sheet of flexible, low dielectric loss, heat resistant insulating material. As shown, Fig. 1, the overlapping edges of sheets 14, 15 are welded between electrodes 1, 2 having covering sheets 5, 6 of woven fabric made of " Terylene " (Registered Trade Mark) impregnated with a synthetic resin varnish or of woven glass fabric impregnated or coated with a silicone resin or silicone rubber. The apparatus is provided with means for pressing the electrodes together and an adjustable stop to prevent the electrodes approaching closer than about the combined thickness of the cover sheets and one of the sheets 14, 15. Instead of the sheets being overlapped as shown, they may previously have been seam welded face to face by an electrode which simultaneously trains off the waste material at the seam. The sheets are then opened out flat and the upstanding seam placed between electrodes 1, 2 which operate to smooth the existing seam.

Filed: 1991-03-19
Abstract: An antenna construction with a rod-shaped antenna element is adapted for use preferably in portable telephones. The rod-shaped antenna element is adapted to be slidably moveable in a tube between a first position in which substantially the entire rod-shaped antenna element protrudes from the tube and contributes to radiation, and a second position where just part of the rod-shaped antenna element protrudes from the tube and contributes to radiation. The rod-shaped antenna element is adapted to be received in the tube to provide a coaxial transmission line. The coaxial transmission line is adapted such that in the second position where part of the antenna element is received in the tube, it has a length and is terminated in a manner such that the impedance of the transmission line is high seen from the protruding part of the antenna element and thus does not affect this part. The coaxial transmission line may e.g. be an open half-wave transmission line. However, the transmission line may also be realized in the form of a short circuited quarter-wave transmission line or an open, shortened half-wave transmission line.

Patent GB-654850-A (GB)
Title: Improvements in or relating to methods of making stable silica sols
IPC: C01B33/145
Filed: 1948-01-06
Abstract: Stable silica sols are obtained by reacting an acid with an aqueous inorganic silicate and cooling the resultant sol, whereupon the greater part of the inorganic salt formed during the reaction is precipitated and is subsequently separated.  More complete removal of the inorganic salt is effected by adding a small amount of a water-miscible organic liquid, e.g., ethyl or propyl alcohol, acetone or 2-methoxy-, 2-ethoxy- or 2-butoxy-ethanol, to the sol before or after, but preferably prior to cooling.  To facilitate precipitation of the salt, when sulphuric acid is the mineral acid employed, the aquasol may be partially cooled and then seeded with sodium sulphate crystals prior to the addition of the organic liquid or the application of the final cooling.  The sol is preferably cooled to 0 DEG  C.  The aquasols so prepared may be converted to organosols by adding a high-boiling water miscible solvent such as 2-methoxy-, 2-ethoxy- or 2-butoxy-ethanol, and subjecting the mixture to vacuum distillation to remove the water.  Specification 649,896 is referred to.
Patent GB-366987-A (GB)
Title: Improvements in the manufacture of solutions of fibroin
IPC: D01F4/00
Filed: 1930-09-10
Abstract: Fibroin is dissolved in cuprammonia solution containing not more than 4 molecules of ammonia to one atom of copper, and preferably the solution is cooled during its preparation where practicable and during its storage, if any, to a temperature below 0 DEG  C. and preferably 0 DEG  to -15 DEG  C.  A solution is thus obtained of high viscosity suitable for the production of artificial silk.  To reduce the degradation of the fibroin it is preferable to remove a part of the ammonia so that the solution contains not more than 2 molecules of ammonia to one atom of copper.  This may be effected by suction or by passing through the solution a current of an inert gas, in which operation it may be necessary to raise the temperature to 25 DEG  C.; or the fibroin complex may be precipitated from the solution by salt solutions such as ammonium sulphate, sodium sulphate or sodium chloride or by organic liquids soluble in water such as methyl or ethyl alcohol or acetone, the precipitate being then redissolved in water.  The quantity of copper hydroxide should be not more than 30 parts copper to 100 p  parts air-dry degummed fibroin.  This avoidance of an excess of copper allows the solution to be filtered through a cellulose filter such as wadding without causing the filter mass to swell. If copper salts are used for the production of the solutions, there must be used sufficient alkali to convert all the copper into hydroxide, but excess of alkali should be avoided.  In examples, (1) a paste of copper hydroxide containing 330 parts copper is kneaded at -2 DEG  C. with 1000 parts degummed silk waste and 981 parts of 22 per cent ammonia; 2360 parts water are added and the solution after filtration is ready for spinning; (2) a paste of copper hydroxide containing 45 kilos copper is mixed with 165 litres of 22 per cent ammonia and 150 kilos of air-dry fibroin at -3 to -4 DEG  C.; 150 litres of water are added during the introduction of the last half of the fibroin, and the mixture is stirred while slowly adding a further 350 litres of water and filtered; the solution is placed in a closed vessel having a stirrer or in a rotary drum, and the pressure is reduced to 12-15 mm., the temperature being raised by a water jacket, but not above 25 DEG  C.; if the solution contains less than 2 molecular proportions of ammonia, it is again filtered before being spun. Specification 366,963 is referred to.
