Title: Improvements in switches for bases for electric flat irons
IPC: D06F79/02
Filed: 1935-12-04
Abstract: 449,854. Retractive switches; thermal switches; magnetic switches. KIECHEL, R., and SOLHARDT, C., (trading as SOLHARDT & CO., C.), Bregenz, Austria. Dec. 4, 1935, No. 33583. Convention date, Dec. 6, 1934. [Class 38 (v)] A mercury-tube switch arranged in the stand of an electric iron is tilted to break the circuit or reduce the current when the iron is placed on the stand ; or alternatively, if desired, the current can be left on and the mercury tube then automatically tilted by the operation of a fusible device when the iron becomes too hot. In the form shown in Fig. 3, when the iron is placed on the upper plate g of the stand, it attracts upwards a magnet k causing the platform i carrying the mercury switch to tilt about a pivot h. If it is desired to leave the current on, a lever n is moved into a position 1 to prevent the magnet moving upwards. When the iron becomes too hot fusible material that holds a plate e fixed to another plate behind it, melts and the plate e swings downwards under the pull of a hook member which carries the pivot h, the hook eventually slipping off the plate e. The pull is due to the weight of the mercury switch or a spring and the mercury switch swings downwards to break the circuit about a pivot x. The plate e is automatically reset by a spring and the switch is reset by moving the lever n into position 2. In a modification, Fig. 5, placing the iron on the stand tilts the top plate g and with it the mercury switch. The top plate can however be retained in the tilted position shown by a catch r, and the fusible device e then releases the mercury switch as before when the iron becomes too hot.

Title: Improvements in or relating to textile twisting frames
IPC: D01H1/36
Filed: 1962-08-31
Abstract: 956,747. Hydraulic apparatus. NEUMUNSTERSCHE MASCHINEN-UND APPARATEBAU G.m.b.H., NEUMAG. Aug. 31,1962 [Oct. 31, 1961], No. 3606/62. Heading F1P. [Also in Division D1] In a twisting-frame having a hydraulicallycontrolled ring-rail, the speed of stroke of the rail is changed by tilting a pump by a movable spindle connected to the pump. Rails 4 on opposite sides of the frame are connected by a member 5' secured to the piston 52 of a valve 6 which is also connected to a switch 7. Upper and lower contacts of this are connected by leads 33, 34 to windings 32a, 32b of a magnetic switch 32. This controls pistons 35a, 35b of a valve 9 connected by pipes 17a, 17b to chambers above and below piston 52, and having chambers 9a, 9b, 9c defined by the pistons, the middle chamber being connected to the outlet side of a pump 10. When the rails complete their upward travel, the switch 7 engages the upper of two fixed members 8a, 8b so that the lower of its two contacts is closed to establish a circuit to the upper winding 32a, which then attracts the armature 32c and moves the piston upwardly to bring the pumpline 16 into communication with the line 17a leading to the upper chamber of valve 6 so that the piston moves down and lowers the rails. At the other end of its travel, the switch 7 engages the lower member 8b to close its upper switch and energize the lower winding 32b to reverse valve 9 to raise the rail. The stroke of the pump 10 varies according to its inclination to the driveshaft of motor 38. The pump is connected by a fork 40 to a block 41 on a shaft 42. The tilt can be varied in a number of ways to change either the basic speed of the ring-rail, or its speed during the build of the package, e.g. to accelerate the downward movement of the rail and slow its upward movement. For changing the tilt, (a) the rod 12 and block 14 are threaded and a rotary handle 14 may be connected to the rod by a clutch 13, (b) a motor 21 may drive the shaft through change-gears 22, 23, (c) the motor 21 may be connected to the shaft through a continuously variable transmission or through a cam on the motor spindle which rotates the spindle intermittently, the motor being reversed at the end of each traverse through switch 7, (d) the piston 42 of a valve is connected to the shaft 12 and branches 18, 19 with throttle-valves 53, 54 taken off lines 17a, 17b are connected one on each side of the piston; thus when there is pressure in the line 17a and the rail is descending, the piston 42, shaft 12 and block 41 move to the left.

[Also in Division F2] Web impurities, e.g. vegetable waste, nap and short fibres, are removed from a carded web by a cleaning device comprising a driving cylinder 1 and a hollow pressure cylinder 3 resting tangentially thereon. The hollow pressure cylinder 3 is positioned by retaining rollers 4. The retaining rollers 4 are positioned on that side of the plane containing the axes of cylinders 1 and 3 towards which the circumferential portions of the cylinders move directly after parting their line of tangency. The cylinders 1 and 3 and retaining rollers 4 occupy relative positions such that the line of tangency between cylinders 1 and 3 is on the same side as the retaining rollers with respect to the vertical line passing through the axis of the driving cylinder. The hollow pressure cylinder is traversed through its centre by an application bar 5 which is mounted (e.g. by pressure springs 7) on the machine frame so as to be movable transverse to its length. The bar 5 presses on the hollow pressure cylinder 3 exclusively via application rollers 6 which are suspended by elastic means 10. These rollers 6 are placed at intervals along the bar. The application rollers 6 are positioned so that their generatrix of contact with the pressure cylinder 3 is adjacent to the plane containing the axes of cylinders 1 and 3 on that side where the retaining rollers 4 are located. In operation the pressure cylinder 3 and the application bar 5 are able to move, in sequence, away from the driving roller 1.

In operation, the crossed loops are turned until a straight line indication is obtained upon the screen of the C.R.T., showing that the plane of the vertical loop is normal to the direction of the ground wave, i.e. that that wave is inducing no E.M.F. therein, and that both loops are receiving only the ionospheric wave, the E.M.Fs induced thereby being in phase. In a second embodiment (Fig. 2, not shown) means are provided for rotating the crossed loops through 90 degrees in the plane of the vertical loop, so that the originally horizontal loop becomes a second crossed vertical loop. In conditions where the ionospheric wave is not significant, the direction finder may then be operated in known manner, with the crossed loops stationary and with a direct bearing being given by the angular position of the trace upon the screen of the C.R.T. In a third embodiment (Fig. 3, not shown), a second vertical loop at 90 degrees to the first is provided with means for switching either it or the horizontal loop to the input terminals of the appropriate channel of the C.R.T., so that operation in either of the two modes described above is readily available.
