Abstract: A bimetal snap disc thermostat is disclosed in which a steel disc cup is provided for strength and/or environmental resistant properties. Positioned within the disc cup is a disc seat formed of aluminum. A bimetal snap disc is positioned in the disc seat and operates the thermostat switch through an axially movable bumper. A ring of rubber like foam material is positioned between the body assembly and the disc on the side of the disc remote from the disc seat. The aluminum disc seat reduces temperature calibration drift of the disc during the cycling of the disc which occurs during the use of the thermostat. The foam ring also tends to reduce bouncing and thereby tends to reduce temperature calibration drift. Also the ring functions to insure that the disc remains properly seated in its aluminum disc seat.

Abstract: Apparatus for sensing and measuring the torque output of a rotary device such as a gear reduction box by inserting an especially machined or configured ring between the shaft bearing and the bearing mounting housing. This ring will have strain gages mounted on it in spaced locations so that axial movement of the shaft will produce a deflection in the ring which will be detected by the strain gages. The strain gage signal then will be sensed, amplified and can be recorded on an analog read out type meter or monitored continuously on a pen-type recorder or other conventional instruments. The strain gage device can be calibrated so the output of the record will convert the signal so that a direct reading of the torque output of the shaft can be made.

Abstract: Disclosed is a clamping means for securing filter bags in a bag filter device. The bag filter device has a filter chamber separated from a plenum chamber by means of a partition having openings therein through which the filter bags extend from the plenum chamber into the filter chamber. Gas to be filtered is passed into the filter chamber and flows through the walls of the filter bags from the outside to the inside thereof and thence into the plenum chamber prior to being discharged from the filter device as cleaned gas. The partition has a stationary shoulder surrounding each opening on the plenum chamber side. The open end or cuff of each filter bag is clamped between the shoulder and a clamping ring so as to secure the filter bag in the partition and to effect a seal which prevents leakage of unfiltered gas into the plenum chamber from the filter chamber. The seal is maintained by the influence of gravity or by a seating or force-applying means.

Abstract: A capping machine turret has a number of circumferentially spaced screw-cap applying spindles with a cap engaging chuck at the lower end of each spindle. Each screw cap applying spindle of the capping machine is rotated by means which frictionally applies an accurately predetermined torque to the spindle and therefore to the cap engaging chuck at the lower end of the spindle. This is accomplished by providing a pair of pinions which are rotatably mounted on each spindle and are continuously rotated by drive means associated with the turret generally. Drive washers are provided at the outer radial faces of the two pinions and between the pinions and these drive washers have internal spline formations which interfit with external spline formations on the spindle.

Abstract: A detent device for a magazine cap on a tubular-magazine firearm, in which the magazine spring is employed to urge a detent member at the front end of the magazine into engagement with a detent surface inside the cap in order to prevent accidental loosening of the cap.

Abstract: A tap-driving chuck, having a driven shaft and a driving sleeve spaced co-axially from the shaft to provide an annular space closed at one end by an annular flange extending from the sleeve. Several circumferentially-spaced balls are positioned in the annular space and are urged by a spring into shallow depressions formed in the annular flange. The balls are each located in slots in a circumferential edge of a flange on the shaft. A driving torque applied to the sleeve is transmitted by the balls to the shaft only while the balls are urged by the spring into the depressions. The balls are lifted against the spring force out of the depressions when the torque being transmitted reaches an upper limiting value, the sleeve then turning idly past the balls.
