Title: Improvements in and related to yarn tensioning devices for textile apparatus
IPC: B65H59/16
Filed: 1951-06-01
Abstract: 718,371. Electro-magnetic yarn tensioning devices. CELANESE CORPORATION OF AMERICA. June 1, 1951 [June 3, 1950], No. 13079/51. Classes 120(2) and 142 (1) A yarn tensioning device comprises a wheel or pulley adapted to be engaged and driven by a yarn that is drawn past it, an electromagnet and an electric conductor that are rotatable relatively to one another by the connection of one of them to said wheel or pulley, said conductor extending into the field of said electromagnet so as to apply to said wheel or pulley a braking force whereby tension is imparted to said yarn, and means for adjusting the energizing current of said electromagnet so as to adjust said braking force. As shown, the yarn tension device 13 includes a magnet 18 comprising a coil 19 and pole pieces 21 fastened to a supporting plate 14 by screws 22. The ends of the pole pieces are bent to form an air-gap 23 in which a strong magnetic field is produced when an electric current flows through the coil 19. A sleeve bearing 24 extends up the centre of coil 19 and has mounted therein a wheel assembly 25 comprising a shaft 26 carrying a wheel 27 and a soft iron disc 28. The shaft 26 is supported on a screw 29 threaded through plate 14, the screw 29 providing means for adjusting the position of the disc 28 in the magnetic field of the magnet. A locknut 32 locks screw 29 in any adjusted position. Yarn 11 is directed to the wheel 27 by trumpet guide 36 and after passing around the wheel leaves it and passes through a guide 39. The yarn 11 causes the wheel assembly 25 to rotate, thereby moving the disc 28 in the magnetic field in the air-gap 23 thus generating electric currents in said disc which tend to oppose the rotation of the disc and exert a braking force on the wheel assembly to tension the yarn. The magnitude of the braking force may be controlled by varying the current in coil 19 or by varying the air-gap 23. Any number of such tensioning devices may be employed in,. for example, a beaming operation, in which case they can be connected in a common electric circuit and adjusted to exert the same tensioning force on each yarn. Arrangements are also described for textile apparatus incorporating tensioning devices as above, in which the braking force applied in each device is automatically varied as the apparatus is stopped, and for automatically changing the amount of this variation in accordance with the changes in the inertia of moving parts in the apparatus. Specification 669,964 is referred to.

Filed: 1959-04-17
Abstract: 881,572. Semi-conductor devices. MULLARD Ltd. April 17, 1959, No. 13178/59. Drawings to Specification. Class 37. A method of making a semi-conductor device comprises roughening a surface of a semiconductor body to produce a damaged layer extending into the body, applying a material to the damaged layer and alloying it to a depth greater than that of the layer. In one embodiment a monocrystalline wafer of 4 ohm. cm. germanium has its upper and lower surfaces lapped to produce damaged layer 10 Á thick. After etching in boiling hydrogen peroxide to remove the outer regions of the damaged layers, an indium sphere is placed on the wafer and the assembly heated to 600‹ C. for 5 minutes in hydrogen to provide on cooling a recrystallized P-type layer extending into the undamaged core of the wafer. The wafer is subsequently treated in a hydrofluoric-nitric acid etch and washed. After conductors have been attached to the body and residual indium mass the assembly is subjected to a prolonged drying before encapsulation. In an alternative arrangement the wafer is boiled in hydrochloric acid, to preferentially dissolve any iron particles transferred from the lapping wheel, instead of or before or after being etched in hydrogen peroxide.

Abstract: 1494049 Yeast SOC ITALIANA RESINE SIR SpA 2 April 1975 [19 April 1974] 13525/75 Heading C6F [Also in Division C3] A process for recovering protein material from live yeast cells involves growing a submerged culture of bacteria of the genus Cytophaga thereby to form a cellulolytic enzyme complex for the lysis of the live yeast cells, and directly utilizing the resulting culture filtrate including the enzyme complex for the lysis of the live yeast cells without subjecting the live yeast cells to any pre-treatment. The culture medium used for growing the submerged culture may comprise 0À5-2 wt. per cent dry matter of live yeast and 0À1-0À5 wt. per cent as dry matter of autoclaved yeast, the yeasts being of the same species as that to be subjected to the lysis. The lysis operation is carried out by contacting the culture filtrate with a suspension of the live yeast cells under agitation at a temperature of 40 to 45C for 2 to 4 hours. The Examples describe the microbiological production of the cellulolytic enzyme complex from a strain of Cytophaga and the lysing by the complex of cells of Candida Lipolytica, Candida vini, Candida utilis and Kloeckera sp., obtained from fermentation on paraffin, ethanol, beet or cane sugar molasses and methanol substrates, respectively. In each case the culture medium for the Cytophaga consisted of 0À2% of the relevant yeast autoclaved at 110C for 20 minutes plus 1À2% of the live yeast, in sterile spring water. The amino acid compositions of an initial yeast biomass from paraffin and of the lysate produced according to the invention are shown to be closely similar.

Filed: 1934-05-07
Abstract: 437,893. Grading eggs by weighing. BINGHAM, G. C., The Friary, Maldon, Essex. May 7, 1934, No. 13766. [Class 143] In machines for grading eggs a series of egg-weighing levers are supported between the rims of one or more wheels mounted on approximately horizontal axes. As shown in Fig. 1, the weighing levers A are pivoted between the rims of a single wheel D. Adjacent each weighing lever is pivoted a counterweighted locking lever B provided with a notched portion S. The wheel revolves in the direction of the arrow, due to the weight of the eggs or by power. As a weighing pan A1 arrives at or near its highest point, an egg is placed thereon. A counterweight B1 on the locking lever engages a stationary cam C1 thereby withdrawing the notched end of the locking lever from the knife-edged extremity A3 of the weighing lever and freeing the same. The weight of the egg depresses the weighing lever, but before completion of the weighing the lever is again locked as the locking lever passes beyond the cam. A second cam C again releases the weighing lever and the weighing is completed, after which the weighing lever is again locked to the locking lever by the appropriate notch therein. The weighing lever whilst still locked is carried round and the egg rolls off the pan on to one of the platforms N1 ... N4 according to the inclination of the weighing lever. In a modification, Fig. 3, the weighing levers E2 are mounted upon supports F pivoted on the rim of a wheel G and provided with tail rods F1 slidable in rotatable pins carried in the rim of a second wheel H coupled by chain gearing to the wheel G. Stops F2, F3 on the supports F limit the movements of the weighing levers. In operation, as the wheels rotate, each weighing lever picks up an egg from an inclined trough I. The weight of the egg presses the weighing lever onto the stop F2. As the wheels rotate, the weighing lever is tilted and the egg rolls gradually nearer to the fulcrum until the weighing lever overbalances and the egg rolls to the other end of the lever and is taken off by one of a series of collecting supports N5 (one only shown), appropriate to the grade. In a further modification, Fig. 5, the two wheels are pivotally connected by vertical links K on which the weighing levers L1 are mounted. The eggs are pushed by a stationary cam P towards the fulcrums of the levers as the wheels revolve until the levers overbalance and the eggs roll to the other end and are taken off as described above. The arrangement shown in Fig. 5 may be modified by reversing the weighing levers on their pivots and feeding the eggs on to the loaded ends.
