Title: Roll-driving mechanism for a napping machine
Inventor: DOURDEVILLE THEODORE ALBERT
IPC: D06C11/00
Filed: 1955-12-05
Abstract: 799,281. Fabric napping machines. GESSNER CO., D. Dec. 5, 1955, No. 34844/55. Class 42 (1). A planetary type napping machine has a set of pile rollers R, Fig. 1, and a set of counter pile rollers R<SP>2</SP>, hydraulic motors H, H<SP>2</SP> driving the two sets of rollers R, R2 respectively, first adjustable means to regulate the supply pressure of one motor and second adjustable means to regulate the discharge pressure of the other motor. As shown, cloth C passes around a front feed roller 41, over the napping rollers and around a rear feed roller 42. The heads 12 carrying the napping rollers are mounted on a driven main shaft 11 which also drives rollers 41, 42 so as to feed the cloth through the machine at a predetermined rate. A pump P, Fig. 3, with a constant volume output delivers liquid as shown to motors H<SP>2</SP> and H and thence to a tank T. The counter-pile rollers R<SP>2</SP> exert a pull on the cloth, but the pile rollers R are driven by the cloth so that motor H acts as a pump and provides a braking effect on rollers R. Supply pressure to motor H<SP>2</SP> is regulated by a by-pass valve V and indicated on a gauge G<SP>2</SP>. Discharge pressure from motor H is regulated by a valve V<SP>3</SP> and indicated by a gauge G. The back pressure in pipe 52 connecting the two motors is controlled by a reducing valve V<SP>2</SP>. The two sets of napping rollers are thus independently torque-controlled. If it is desired to operate motor H or H<SP>2</SP> at a constant speed, an automatic speed control device may be provided to adjust valve V or V<SP>3</SP> in response to slight variations in motor speed.

A filter network whose input is derived from between two points on a first inductance, includes a second inductance coupled to the first inductance in such a manner that the voltage induced by the coupling is 180 degrees out of phase with the voltage which would otherwise appear across the second inductance. The circuit shown is a push-pull audio amplifier for an A.M. transmitter, the anodes of valves 2 and 1 being respectively connected to one end of the primary winding 9 of an output transformer and to a tapping-point on the winding. The other end of the winding 9 is connected to an inductor 11 constituted by a winding on the same core as winding 9. This is combined with capacitors 12, 13 to form a low-pass filter network. The anode power supply for the power amplification stages is fed from a constant voltage source 10 through winding 11 to the output terminal of the filter. The current supplied to the power amplifier thus varies with the filtered signal frequency so that the output of the transmitter is amplitude-modulated.
