Abstract: The description relates to a device for air conditioning control in an air-conditioned room containing textile machines, especially circular spinning and spooling machines, with an air feed and an air discharge duct connecting the air-conditioned room to the air conditioning unit. A first set of sensors for measuring the temperature and relative humidity of the air in the room is connected for the control purposes to a first regulating circuit, and a second set of sensors for measuring the temperature and relative humidity of the feed air is connected for control purposes to a second regulating circuit. The first and second regulating circuits are connected in cascade, the first regulating circuit supplying a reference value to the second regulating circuit which controls the adjusting components of the air conditioning unit.

Abstract: A container, such as for delivering merchandise to retail stores has an internal space partly defined by a partition 22 which is movable to allow the size of the container space to be varied to suit different goods. For instance, when carrying eggs, the partition can be moved to allow different sizes of egg box to be held without movement, thus reducing vulnerability of the eggs to damage during transport.

Abstract: An automatic hunter's prop is adapted for quickly lifting a hunter lying on his back in a camouflage position to a ready position for shooting game. The hunter's prop includes a base frame for being positioned on a ground surface, and a launching frame connected to the base frame. The launching frame is pivotable between a tension-loaded condition wherein the launching frame extends generally parallel to the base frame, and a tension-released condition wherein the launching frame extends upwardly at an angle to the base frame. A pair of coiled springs increase tension in the launching frame when moved from the tension-released condition to the tension-loaded condition. A releasible catch and hook cooperate to releasibly set the launching frame in the tension-loaded condition. A trigger cord releases the catch from the hook and rapidly pivots the launching frame upwardly into the tension-released condition.

Abstract: A disposable cover for a stethoscope for being placed in a tensioned condition over and covering a patient-contacting portion of the stethoscope. The cover includes an elastomeric material defining a disc-shaped body, a raised rim integrally-formed with and surrounding the body, and a centrally-disposed, raised dimple integrally-formed in the body for being grasped and pulled away from the stethoscope when removal of the cover from the stethoscope is desired. The cover may include perforations or some other form of weakness area which tear the cover to facilitate removal when desired.

Abstract: A body protective garment is adapted for covering a hip region of a wearer to protect the wearer against femoral fracture resulting from a sudden impact. The body protective garment includes an elastic girdle having a waist opening and a pair of leg openings. A plurality of pad-receiving pockets are attached to the girdle and adapted for overlying the hip region on opposing anterior sides and a rear thereof. A plurality of removable body protective pads are carried in the pockets. Each of the pads includes a multi-layer foam composite capable of reducing a 5800 N impact force to less than 1200 N.

Abstract: A protective garment includes an abrasion-resistant fabric attached to an inside of the garment, and having a face side residing adjacent the garment and a back side for residing nearest the wearer. The fabric includes a body yarn, and an elastic yarn incorporated with the body yarn. A high performance yarn is incorporated with the body yarn and the elastic yarn, and terried to form loops extending from the face side of the fabric adjacent the garment. The high performance yarn has a tensile strength of at least 7 grams per denier.

Abstract: A method of reducing trash recirculation into the fiber formation stream of an open-end spinning machine yarn formation station of an open-end spinning machine of the type having a movable trash belt which collects trash removed from sliver during yarn formation, said spinning machine having a predetermined, relatively high, conventional trash belt speed, comprising the steps of moving the trash belt at a low speed determined by the type of trash contained in the fiber, the type of yarn being spun and the type of fabric to be formed from the yarn, but in no event more than 50 percent of the conventional trash belt speed. The low speed of the trash belt is between 15 and 40 percent of conventional trash belt speed, with the low speed increasing as the proportion of heavy to light trash in the trash mixture increases.

Abstract: A head assembly for a medical handpiece includes a head housing and a rotor spindle contained in the housing. The spindle defines a longitudinal through-bore with an internal screw thread. An adjustable chuck is received within the through-bore of the spindle and has a complementary external screw thread adapted for mating with the internal thread of the spindle. The chuck has a top opening forming a keyway and a bottom opening adapted for receiving and holding a bur. A chuck key is attached to the housing, and includes a hand grip at its top end for being manipulated by a user and a chuck engaging bottom end. The chuck key is axially moveable between an operative position and an inoperative position. Upon rotation of the chuck key in the operative position, the chuck threadably moves relative to the spindle to an open position for receiving and removing the bur.

Abstract: A stretch-forming machine of the type wherein a pair of opposed curving jaws grips opposing ends of a metal sheet to be stretch-formed in a curved configuration. Each of the jaws are formed of an array of adjacent grippers movable relative to each other by respective hydraulic cylinders to define a part of the curve of the jaw. The improvement to the stretch-forming machine which is the subject of this application comprises a closed-loop servo-control means for moving each one of the grippers into a predetermined position relative to each other. Each of the servo-control means comprises a hydraulic cylinder position controller carried by the hydraulic cylinder of the one gripper for controlling hydraulic fluid flow to the hydraulic cylinder responsive to stored data representing the desired predetermined position of one of the grippers. A motor is provided for actuating the position controller in response to the data received by the position controller to move the hydraulic cylinder.
