Abstract: 323,031. Wade, H., (Syntheta Akt.-Ges.). July 13, 1928. Apparatus for making filaments; cellulose acetates, processes for making filaments from.- To permit the employment of winding speeds of the order of 600 feet per min. or higher in the arrangement of artificial silk by the dry spinning method, the air in the spinning cells is heated to a temperature substantially higher than the normal, for example, to 140‹ C. in the case of acetone solution of cellulose acetate, and precautions are taken to prevent the spinning solution being heated to a temperature above the boiling point of the solvent before its passage though the spinning nozzles. In order to ensurethat heating of the solution shall not occur, both the spinning nozzles 3, Fig. 2, and the wall 13 of the cell in which they are located, should be water cooled, the air in the cells being heated by a band of steam pipes 12. In the construction shown, the nozzles 3 are mounted at the extremities of hinged arms 24 provided at the end adjacent the nozzle with a plug 9 adapted to enter loosely a correspondingly-shaped socket in the water-cooled roof 13 of the cell; the filter chamber 39 is mounted on the arm 24 and is also water cooled. The spinning element may comprise a solid body 18, Fig. 5, provided with a hollow collar 14 constituting the cooling- member and serving also to hold the nickel spinning nozzle 16 in place; or, alternatively, the body 32, Fig. 6, may be hollow, so constituting the cooling-member, and in this case the spinning nozzle 16 is mounted independently in a capsule 29 which is held in position by the collar 25. The walls of the cells are lagged with cork 41, and in the bottom of the cells are provided sliding doors 49, Figs. 2 and 4, with notches 10 on opposite edges to furnish an outlet opening for the thread. At starting, the cells are heated to suitably high temperature, the spinning arms are lifted to expose the underside of the spinning nozzles, the bead of solution formed on the nozzle is removed by pincers, and the nozzle wiped in order to enable the filaments to be extruded.

Abstract: 436,810. Drilling-machines. ARCHDALE & CO., Ltd., J., and JEWSBURY, J., Ledsam Street, Birmingham. July 16, 1934, No. 20785. [Class 83 (iii)] In a radial-arm drilling-machine of the kind wherein the arm is vertically slidable but not rotatable on a sleeve, the arm is locked to the sleeve by a weight or spring and is released by a fluid pressure cylinder, an electric motor being provided for raising or lowering the arm and for driving a pump to supply the cylinder and means being provided whereby a clutch connecting the motor to the raising &c. mechanism is under control of the fluid cylinder. The machine, which may be of the kind described in Specification 395,463, comprises a vertical shaft a for locking the arm to the sleeve which is actuated in the locking direction by a weight or spring acting on a lever b through a link. c. The lock is released by a hydraulic cylinder g whose piston f carries a rack e acting on a pinion d on the shaft a. The cylinder g is supplied with oil from a pump m driven from an electric motor through gearing k. A screw for raising and 'lowering the arm is driven through gearing l and a clutch i from the motor j. In operation, to raise or lower the arm, the motor is started and the pump m supplies oil, irrespective of its direction of rotation, to the cylinder g to release the arm. After a predetermined travel an extension of the piston f acts on a bell-crank lever h to move the clutch i and connect the gearing to the motor, a lost motion connection being provided to ensure that the arm is released before the clutch is moved. When the piston f reaches the limit of its travel, the oil supplied by the pump returns to the sump through an adjustable valve n, and when the motor is stopped, the weight or spring rotates the shaft a to locking position, the cylinder g discharges through the valve n and the clutch i is disconnected. In an alternative construction the cylinder g is connected to the shaft a and the piston f is fixed.

Two similar groups of electric motors 1, 2 and 3, 4 have associated series resistors R1,2 and R3,4 respectively, each of which is subdivided-and has an intermediary point IM1 or IM2 connected over contactors JR2 or JR1 to the motor circuit of the other group to provide resistor portions for individual correction by a notching operation of a common controller. For starting, main switch L, earthing contactor E and contactors JR1, JR2 are closed, contactors P and G between the resistors and the supply remaining open, to provide series operation of the motors and parallel operation of parts of the resistors. Contacts 1 to 9 are then closed sequentially by operation of the controller. During bridge transition the contactors P, G are closed for parallel operation of the motor groups and series correction of resistor portions, and contacts 10 to 19 are then sequentially closed for short-circuiting those resistor portions not used for series motoring. For rheostatic braking, contactors B1, B2 in a connection between the motor groups are closed together with contactors P, G so that the armatures of one motor group are in circuit with the field windings and resistors associated with the other group, portions of the resistors then being short circuited in exactly the same sequence as used for the motoring operation. Reversing contactors J1, J2, J3 and J4 and field short resistors SR1 and SR2 are also provided.
