Title: Angular rate sensing apparatus and method
IPC: G01P3/26
Filed: 1981-11-11
Granted: 1987-08-26
Abstract: An output system (186) for a fluidic angular rate sensor (74, 314) or other device having two fluid pressure outputs is used to convert the dual outlet pressure signals to a pair of oscillating electrical signals whose relative frequency differential is very accurately indicative of the outlet pressure differential of the sensor or other device. The dual outlets of the sensor or other device are fluidically coupled to the control ports of the first amplifier (256) in a cascaded series of fluidic proportional amplifiers (256, 258, 260). The outlet ports of the terminal amplifier (260) are coupled to the inlet ports of a pair of fluidic oscillators (262, 264). A pair of microphone type-pressure-to-electric transducers (266, 268) are driven by the oscillators to produce the oscillating electrical signals. The system is applicable in the field of navigational guidance systems (10) for deriving pulsed electrical angular rate signals representing rotations about up to three control axes utilising fluidic angular rate sensors (74, 314) in place of conventional mechanical rate gyroscopes.

Abstract: A compact feeding module in the base portion of an electronic or mechanical sewing machine is driven via an input shaft provided with two cam disks (32, 33), one of which, the feeding cam disk, drives by a link a guide (37) in an oscillating movement. A block (40) journalled on a shaft secured to a slide (44) can be displaced in the guide by a mechanical or computer controlled electrical setting means. The slide is journalled in the feeder and displaceable perpendicularly to the working direction of the feeder. By a displacement of the slide the block will move into a corresponding  position in the guide thereby bringing about an adjustment of the feeding. The other cam disk, the level control disk, acts upon a link (50) connected to the transferring means to the feeder and is coordinated with the above said disk to guide the feeder in a rectangular movement.

Abstract: In the conventional discharge printing on polyamide fiber materials using acid dyes, above all, the very low wet and light fastness properties of the designs obtained in this manner are frequently an obstacle to the wide expansion of this interesting technique in practice. Applying this known patterning method for wool or nylon to resist prints made with reactive dyes being distinguished by better fastness level, does not always produce satisfactory white resist effects when, for example, sulfite compounds as the resist agent and reactive dyes having esterified  beta -hydroxyethylsulfonyl groups as the reactive radical are taken into consideration; colored effects having a bright hue are not even possible at all in various cases. It has now been found that, using sulfite compounds and reactive dyes of the vinylsulfonyl type, the above mentioned difficulties can be remedied when, instead of the ester derivatives of said dyestuffs, according to this invention such dyes which have been converted before they are applied into the free vinylsulfonyl form, are brought to interaction with the preprinted resist agent to become immediately and completely desactivated and thus resulting unobjectionable resist effects at the respective places of the textile material.
