Title: Improvements in or relating to hats of woven or knitted fabric
IPC: A42B1/02
Filed: 1925-04-28
Abstract: 243,980. Heusen, J. M. van. April 28, 1925. Making.-Hats of woven or knitted fabric are made by providing a blank having a raised or bulged centra.l portion, treating the blank with a shrinking agent, fitting the treated blank while wet to a hat form, and drying it thereon. As applied to hats of knitted fabrics a curved tube 4, Fig. 2, is knitted on a machine of the type known as a " footer." The tube is cut along the line 2 and dipped in sulphuric acid of 75 per cent strength. After immersion for one minute it is washed in water and the central bulge placed over the crown portion 7 of a block 5. The female block 6 is placed in position and the fabric is firmly pressed between the members 5. 6. The whole is then heated in an oven and the hat is finished as usual. The sulphuric acid acts also as a stiffening agent, and prevents the fraying of the edges of the brim after this is pared. As applied to woven fabrics, a blank which has been provided with a central bulged portion by varying the tension on the threads during the weaving, or by other means, is used.

Title: Method of growing semi-conductors
IPC: C30B15/18
Filed: 1955-04-25
Abstract: <PICT:0779383/III/1> A method of growing semi-conductor crystals comprises immersing a seed crystal in a melt of semi-conductor material containing P, N or both types of impurities and withdrawing the seed crystal slowly to permit the material of the melt to freeze on the crystal, and includes the further step of applying an electric field across the combination of the melt, the freezing interface, and the partially grown crystal to control the spatial distribution of the impurities in the finished crystal.  In operation, the crucible 1, Fig. 1, mounted upon an insulating block 2 contains for example a melt 4 of germanium or selenium with impurities, and is heated by an induction coil 6, the seed crystal 8 being raised from the melt by a cable 10 passing over pulleys 11 to a member 12 slidable in the frame 3 by an electric motor 15.  The electric field across the crystal, interface, and melt is provided by a D.C. through a variable resistance 27, a change-over switch 19, an electrode 21 engaging the material 4 at the bottom of the crucible, and a terminal on the crystal holder 9.  As the crystal is grown the switch is closed in one direction or the other, and the field intensity may be varied by altering the resistance 27.  This variation of field direction and or intensity produces a change in the distribution of each impurity in the growing crystal so that P and N type regions may be produced alternately and the crystal may be grown with any desired specific resistance.
