Title: Improvements in or relating to variable speed gears
IPC: F16H61/662
Filed: 1928-11-02
Abstract: 322,605. Flint, F. P., and Flint, A. V. Nov. 2, 1928. Variable-speed friction gearing comprising discs secured to the driving and driven shafts engaged by rollers rotating on a shaft which is arranged to slant automatically with respect to the load to allow the rollers to move across the faces of the discs is characterized by the method of connecting the rollers and of controlling their position. The driving disc and the driven disc J are rotated by rollers K' - - K<4> mounted on a shaft M supported by springs 0<1>, 0<2> and are connected in pairs by sleeves L<1>, L<2> sliding on the shaft M. A lever P engages the sleeve L<1> at R and the sleeve L<2> at T through an arm W connected to a sleeve U mounted on a control shaft V, and is arranged to shift the rollers to preserve equal speed ratios between the inner and outer rollers. The control shaft has came V', V<2>, and rotation of the shaft disengages the rollers from the discs; a stop V<3> on the shaft V necessitates the gear being placed in neutral, before the lever P is operated to shift the rollers for the reverse. The automatic operation of the gear may be supplemented by the addition of a bell-crank lever which varies the tension of the springs according to the position of the rollers. An alternate construction shows the outer rollers K<1>, K<4> secured to the shaft M, which is arranged to slide through its end bearings to vary the position of the rollers on the discs.

Title: Footwear sewing-machine, especially for welting
IPC: D05B85/00
Filed: 1947-12-05
Abstract: 634,482. Sewing-machines. PEDERSEN, V. Dec. 5, 1947, No. 32124. Convention date, Feb. 10, 1940. [Class 112] A hydraulically operated presser foot 2 is periodically locked, pressed onto the work 23, and released by an arrangement comprising two pistons 6, 12 working in communicating cylinders 30, 31, the piston 6 being connected to a lever 4 carrying the presser foot and the piston 12 being moved from the machine drive shaft 19. The piston 12 is connected to a cam 9 on the drive shaft to move within the cylinder 31 which is connected to an open reservoir 14 by a port 13. Immediately the piston 12 passes the port on its inward strokes the presser foot is locked and further inward movement of the piston increases the pressure of the foot on the work. On the return strokes of the piston 12 the pressure of the foot decreases and is released as the piston reaches the port. Thick work pivots the block 7 containing the cylinders about a pin 16 to lower the piston 12 in the block and to increase the travel of the presser foot. The pin 16 is eccentrically mounted to permit adjustment in the relative positions of the piston 12 and the block and thus to vary the presser foot travel.

Patent GB-600888-A (GB)
Title: Means for modifying abrupt voltage changes in electric arc or discharge converter valves
IPC: H01F38/02
Filed: 1945-11-29
Abstract: 600,888. Converting. ALLMANNA SVENSKA ELEKTRISKA AKTIEBOLAGET. Nov. 29, 1945, No. 32252. Convention date, Dec. 23, 1944. [Class 38 (ii)] In a converting arrangement of discharge valves, to reduce the rate of increase of reverse voltage across the valves during the blocking interval, a saturable reactor is connected in series and a capacitor or resistor is connected in parallel with each valve, their dimensions being such that, upon a sudden voltage change, such a current flows through the parallel impedance and series reactor that the flux change in the reactor is at least “ of the change from total positive to negative saturation, or that the voltage across the reactor takes at least 15 degrees electrical to sink to zero. Saturable reactor 3 and capacitor 8 are connected respectively in series and parallel with a valve 2 forming part of a three-phase rectifier group. The reactor 3 has a D.C. winding 4 the current in which magnetizes the core in the same direction as the load current. At point t-shown in the anode voltage (referred to cathode) curve in Fig. 1-when upon commutation load current ceases in valve 2, the anode voltage would immediately rise to a large negative value but for capacitor 8. This discharges through reactor .3 a current which opposes and possibly reverses the magnetism due to the auxiliary winding 4 the anode volts following line b to reach the transformer volts more slowly at tx. Without unidirectional conducting valves 6, 7 the negative rise in anode volts would increase, as the current through reactor 3 and capacitor 8 are maintained by the current in winding 4 again reversing the reactor magnetism. When this reversal ends, the flux change d being equal to flux change c, the current again suddenly reverses to discharge capacitor 8 through the now saturated reactor. With valves 6, 7 the same voltage path is followed to time tx since the reactor flux change maintains current in winding 4 but thereafter, resulting from the direction of flux change, valve 6 short-circuits winding 4, the current is not maintained through winding 3 and anode volts remain constant at e until flux change f equals flux change c and the anode immediately goes to the transformer voltage. The auxiliary current may be introduced directly into winding 3. Valves 6 and 7 may be omitted and the auxiliary winding 4 reduced or omitted if the reactor is designed to have appreciable hysteresis and eddy currents or a short circuited secondary. In an inverter with large grid phase displacement, the effect of parallel capacitor 8 and series reactor 3, is that the anode voltage follows the path k, l instead of the path h as shown in Fig. 6. Hence the anode will remain negative after the transformer volts are positive and the allowable grid shift can be greater. In these conditions the capacitor 8 may be replaced by another impedance such as a resistor. The properties of suitable reactor cores are discussed, they may for example be of two different magnetic materials.

Abstract: 1,197,622. Data signal processing. TEXAS INSTRUMENTS Inc. 14 July, 1967 [18 July, 1966], No. 32448/67. Heading G4G. [Also in Division H4] In the time-domain filtering of a seismic trace (record) (see Division H4), different filter functions respectively optimum for filtering the trace at different record times are applied in turn to the trace by analogue apparatus. Time-delayed versions of the trace are reproduced by playback heads 20a from record drum 20 and applied to sets of summing resistors 32, 42 &c. which are selected by ganged switches 31, 41 &c., whereby resistors 32 and adder 33 apply a first filter function to the trace, then resistors 42 and adder 43 apply a second filter function to the trace, and so on. Smooth changeover between filter functions is achieved by means of timevaried resistors 34, 44 &c. for weighting the filter outputs. The filter outputs are combined in adder 36 and recorded at 23. Instead of resistor networks, voltage-controlled multipliers and gate circuits may be used for weighting and combining the outputs of heads 20a (Fig. 4, not shown).
