Title: Biologically active fission products of the chorionic gonadotrophin
IPC: A61K38/24
Filed: 1951-07-25
Abstract: Dialysable biologically active fission products of the chorionic gonadotrophin are obtained by hydrolysing the gonadotrophin and simultaneously dialysing the reaction solution, the fission products being isolated from the dialysate.  The hydrolysis vessel is preferably a tube of flexible semi-permeable material e.g. "Cellophane" (R.T.M.), collodion or parchment, closed at one end, capable of being rotated, and arranged within a somewhat larger glass tube which is immersed in a water bath at a predetermined temperature (e.g. 30 DEG  C.).  The external liquid used for dialysis has approximately the same pH as the internal liquid. The external liquid is continuously renewed.  It is preferred to use the pure hormone; and the hydrolytic agent is preferably a proteolytic enzyme such as pepsin or trypsin.  In one example, a purified sample of chorionic hormone is dissolved in 0.1 N acetic acid containing pepsin; and in the other example, the gonadotrophin is dissolved in an aqueous ammonia solution of trypsin of pH 8.0.  The biologically active fission product is isolated from the dialysate by freeze drying.

Abstract: 664,867. Seaming non-metallic6 sheet material. BRITISH UNITED SHOE MACHINERY CO., Ltd. July 7, 1949 [July 8, 1948], No. 17934/49. Class 42 (i). [Also in Group XI] A dielectric sheet seaming machine comprises co-operating electrodes, a source of high-frequency energy, the voltage of which is substantially independent of sheet thickness variation, and a two-conductor transmission line between the said source and the electrodes, of an electrical length of an odd number of quarter wavelengths of the supply voltage. The electrode voltage is thereby automatically varied in proportion to the sheet thickness. In the embodiment, thermoplastic sheets are fed intermittently between electrodes 82, 210, and the electrode 82, which is carried on a rod 80, is reciprocated vertically into and out of engagement with the sheets. The reciprocating motion includes a shaft 30, driven by an electric motor 36, Fig. 3, carrying a cam 100 against which is held a roll 102 on a lever 106 which is pivoted on a pin 108. A spring 116 keeps the roll against the cam, and oscillatory movement is transmitted from the lever through a further lever 112 pivoted on a sleeve 109 fixed to a rod 44. When the sheet thickness increases, idler wheels 59, 64 supported from the rod 44 will rise, lifting the rod 80 and electrode 82 with it. A hand lever 122 may be used to raise the upper electrode and the idler wheels to allow the insertion of sheets, or this operation may be effected electrically by the depression of a pedal, not shown, and during this time high-frequency power is automatically cut off by a switch 132 operated by a leaf-spring 134. The material is fed intermittently between the electrodes by a wheel 74 on a shaft 70 which is rotated step-by-step via a shaft 140 and gearing, all driven from the motor 36. The motor speed is controlled by a pedal, not shown. The electrodes receive pulses of energy from an oscillator 240 during the engagement period and whilst the sheets are stationary. A variable capacitor 338, Fig. 2, in parallel with the transmission line conductors 334, 336 varies the electrical length of the line. To prevent arcing a part 180, Fig. 7, within a slot in the electrode 82 is urged by springs 186 towards the sheets. Alternatively, Fig. 8, the electrode supports by a nut and spring 194 an L-shaped member 190 which pivots about a point 193. Specification 649,038 is referred to.
