Abstract: Extension handle consists of a pair of telescoping handle parts made out of relatively thin-walled plastic tubing. A protrusion on the outer wall of the inner tubular member, formed as by inserting a pop rivet therethrough, frictionally engages the inner wall of the outer tubular member to provide some drag or resistance to axial movement of the tubular members relative to each other. The outer tubular member, being made of relatively thin-walled plastic tubing, will deform more or less according to the amount of interference between the rivet and inner wall of the outer tubular member. A rigid metal or plastic ring at the inner end of the outer tubular member acts as an abutment or stop for the protrusion on the inner tubular member thus preventing the telescoping handle parts from being completely pulled apart.

Abstract: A hand-held, manually operable gauge for measuring the gap between opposing surfaces of a pair of spaced parts includes a pair of reciprocable gauge fingers insertable into the gap and respectively shiftable into engagement with the parts by a lever pivotally mounted on a handle. One of the fingers is stationarily mounted on the handle while the other finger is secured to a plunger slidably mounted on the handle and driven by the lever. Linear displacement of the plunger is translated by a rack and pinion to rotary motion for operating a potentiometer whose setting corresponds to the magnitude of the gap. A switch carried by the handle and activated by the lever produces a signal proportional to the potentiometer setting, which signal is delivered to a device for visually displaying the magnitude of the gap. A lost motion mechanism permits continued displacement of the lever after the gauge fingers have contacted the parts.

Abstract: For continuously drying a cloth, the cloth is subjected to a drying process in which high pressure dry hot air is jetted against the cloth in a zigzag pattern from both sides thereof while transporting the cloth continuously through a cloth passage. The cloth passage is a gap formed between a pair of horizontally extending parallel endless net conveyors located one above the other.

When the drying process is effected by stepwise lowering the temperature of the cloth, or is repeated by cooling the heated cloth in the open atmosphere, the drying resembles natural drying, preventing the cloth from becoming fragile, and moreover, in particular heat energy is saved. A cloth in a ropy state can also be dried satisfactorily and effectively by inserting a cloth untwisting process and a cloth expanding process prior to drying.
