Abstract: 1,227,520. Making corrugated tubing. UNIVERSAL METAL HOSE CO. 17 Oct., 1969, No. 51101/69. Headings B3A and B3E. Annular corrugations 115, Fig. 4, are formed in tubing 24 by apparatus comprising a forming head 22 with rotatable die-rings 110, 112 which encompass the tubing and are movable so that their inner peripheral portions indent opposite sides of the tubing and generate a single annular groove. The die rings 110, 112 are rotatable in bearings 120 which are mounted in adjacent carriers 114, 116 rotatable with a hollow shaft 34 for generating the corrugations. Shoulders 150 on the carriers 114, 116 bear against a bevelclosing ring 100 which is moved endwise, against a return spring 164, for causing the dies to indent opposite sides of the tubing, Fig. 10. Rotation of the shaft 120, with the dies in this position, generates a groove 115. Drive.-A pulley-shaft 42 drives the shaft 34 through gears 48, 50, and drives a further shaft 64 through a pinion 68 engaging gear 50. Wormgears 70, 72, 74, 76 on the shaft 64, through worm-wheels 78, 80, 82, 84, rotate cam-shafts 86, 90, 92, 94 driving cams 88, 58, 60, 62. Cam 88, through a bell-crank 168 or one on each side of the machine, operates the bevel-closing sleeve 100, cam 62 closes further dies 272, 274, 276, and cams 58, 60 operate these dies for compressing the corrugations and advancing the tubing in steps. Tube feeding; corrugation compressing.-A clamp 186 operated by an hydraulic cylinder (210), Fig. 2 (not shown), grips the tubing 24 at one end of the machine and is slidable along rods 192. The feeding and compressing head 22 is at the other end of this machine and comprises a spring-closed, scissors-type carrier 234 (236), Fig. 3 (not shown), opened by the cam 62, and vertically-split supports 254, 256, 258 for the divided dies 272, 274, 276. The support 256 is movable, against biasing springs 262, along bolts 260 fixed to the support 254, the support 258 being movable in a bore 264 in support 256 against biasing springs 266. Operation.-The tubing is advanced by hand or automatically between corrugating steps until it reaches the die-rings 272, 274. With the head 22 closed, Fig. 4, the indenting dies 110, 112 are closed by the cam 88 so as to generate a groove 115 before they open. The cam 60 holds support 258 stationary, while cam 58 moves the supports 254, 256 towards support 258 for partially compressing a corrugation between the dies 272, 274 and completing the compression of an adjacent corrugation between dies 274, 276. The cams 58, 60 then act together to advance the tubing as the carrier 234 (236) slides along its pivot 242. Opening of the carrier by the cam 62 follows and return by the cams 58, 60.

Abstract: 1,228,280. Keyboards giving coded outputs. GENERAL ELECTRIC CO. 14 May, 1969 [4 June, 1968; 9 July, 1968], No. 24518/69. Heading G4H. In a keyboard each key when pressed is adapted to bring an upper member 10B, Fig. 1, into contact with a lower member 10A to modify the magnetic circuit, a first group of leads 21- 27, Fig. 2, being linked or not linked in different combinations with each of the lower members so as to provide a coded representation of the symbol associated with the key pressed, and a second group of leads linked so as to provide the complement, corresponding leads of the two groups being gated together in Exclusive-Or gates 51-57, Fig. 5, so as to give a signal only if the leads of each pair have different signals, the outputs being combined in diodes 91-97 to provide a signal enabling And gates 121-127 to pass the coded pattern. If more than one key is pressed signals appear on both of at least one pair of true and complementary leads and the corresponding gate 51-57 gives a zero output instead of the normal output of- 13 v. The output of diodes 91-97 is then also zero and gates 121-127 remain closed so that no output is given on leads 141-147. With correct operation output signals on leads 141-147 are detected by Or gate 199 and a pulse applied to lead 201 to indicate that a coded symbol is available on the output leads. The input is held briefly by trigger circuits 31-44. The signal from Or gate 199 is also differentiated and applied to a circuit which generates an audible indication that a symbol has been properly keyed. The audible indication may be adjustable in frequency, volume and duration. The keyboard may be used as input to a printer, the coded signals being entered in turn in a circulating memory under the control of timing signals derived from output 201. Successive timing signals are counted to obtain a column number for each symbol. The printer generates a pulse for each character position through which the type drum moves. These pulses are counted to obtain a coded representation of the entire type font at each instant and this number is added to each column number in turn and is compared with the symbol codes in the memory. Upon agreement the column number is gated to a column decoder and the appropriate hammer is operated through a hammer drive circuit, to print the character present at that particular instant in that column.

A method of preparing protamine sulphate from fish sperm (milt) includes the steps of treating the fish sperm or cell nuclei obtained therefrom with a mixture comprising an alcohol and sufficient water and a strong acid other than sulphuric acid to make the mixture a solvent for protamine, the amount of the strong acid being just sufficient to break the protamine-nucleic acid combination but insufficient to degrade the protamine, whereby the protamine is dissolved and the nucleic acids are precipitated, separating the alcoholic solution of the protamine and treating it with sufficient sulphuric acid to precipitate protamine sulphate. In examples, the strong acid is hydrochloric acid and the alcohol methanol or ethanol.

Two rods 14 of plastics material, e.g. nylon, are butt welded by axially aligning the rods 14 so that the end faces 19 to be welded are spaced apart and facing one another, directing a stream of hot inert gas against each face 19 until the ends of the rods have melted sufficiently to form a weld, and axially displacing the rods 14 until the faces 19 are in contact so as to form the weld. The ends 13 of the rods 14, which are to be butt welded to form a mandrel for use in the manufacture of braided hose, are positioned each in a V-slot 12 in a block 11 slidable in rails 15 on a base 16 of a jig 10, the faces 19 projecting beyond the blocks 11. The ends 13 are held by clamps 17. A gas supply device 18 comprises a T-shaped metal tube 20 connected by a tube 21 to a source of inert gas, e.g. nitrogen. The gas is heated by an element 22 which may comprise a resistance wire helically wound on a ceramic core. Preferably, the openings at the ends of the cross-bar of the tube 20 have the same crosssection as the faces 19. After heating, the tube 20 is swung out of the way and the blocks 11 are moved together, by a system of levers or a screw-threaded rod, to bring the faces 19 into light contact to form a slight ridge of melt around the weld. After cooling, this ridge is trimmed off. In modifications (not shown), the hot inert gas may be supplied through separate tubes to each end face 19 or nitrogen gas is heated by passage through a coiled metal tube over which a coal gas or butane flame plays.
