Abstract: A folding container has a base for carrying goods and end walls with corner posts articulated to the base by pins. Each corner post has a heel which just clears a bridge member above its arcuate path of movement. To lock each corner post upright, a locking member can be slid into the gap between the bridge member and the heel parallel to the axis of articulation to transmit compression forces directly from the heel portion to the bridge member.

Abstract: An apparatus is provided for manufacturing a cylindrical member utilizing a pair of dies each of which has a semi-cylindrical recess formed therein and which are adapted to be brought into abutment against each other to form a material disposed within the recesses into a cylindrical form. The abutting surfaces of the pair of dies are offset from a plane which includes the axis of a cylindrical member to be formed within the recesses of the dies and which is perpendicular to the direction of movement of one or both of the dies. In this manner, the formation of a bulge or flash on the outer periphery of the cylindrical member can be prevented which may be formed if the abutting surfaces lie in said plane.

Abstract: The present invention relates to an orthodontic appliance for the treatment of dental malocclusion. Brackets of the present invention, used for securing the orthodontic wire, are all bonded to the internal sides of the teeth, that is, the lingual or palatal side. The orthodontic appliance comprises a plate bonded to a tooth, which plate is connected to the main body of the bracket. The covering orthodontic cap for fixing the wire is connected to the main body of the bracket. The cap can be removed from the bracket since it is fixed and connected thereto with a connecting part and elastic connecting device. The bracket or the cap is provided with a shearing groove that prevents the caps from sliding off and provides for locking and removal of the cap by simple operations.

Abstract: A welding robot having an elongated arm pivotally mounted on an upright turret which is movable about the upright axis thereof. As a result, the arm is swingable about the aforesaid upright axis. A fine movement control device or commuter is mounted on an end of the air remote from the aforesaid pivotal attachment thereof to the upright turret. The fine movement control device has a welding gun mounted thereon with structure being provided in the control device for permitting the welding gun to move through a very fine pattern of movement independent of the movement of the arm. A preprogram is provided for moving the arm in a predesignated direction to coincide with the path of a welding seam. Variations of the welding seam from the preprogram can be controlled by the structure in the fine movement control device so that the welding torch will follow the actual welding seam even if it varies from the preprogrammed path thereof.

Abstract: An air-powered sander is made up of a housing with a compressed air motor within it and designed for driving a sanding pad. The sander has a system for clearing dust, produced on sanding, from the pad. This system is made up of an impellor wheel freely turning on a motor shaft in the housing. On the two sides of the impellor wheel two groups of blades are present. A nozzle, joined with the airway for supplying the motor with compressed air, is used for directing at least one air jet against one group of the blades on the wheel. The other group of blades, on the other side of the wheel, is designed for producing a dust/air current for clearing sanding dust from the pad. For this purpose a dust take-up space is present extending from the pad to a position near inner ends of the second group of blades on the impellor wheel.

The granulator may have an additional device such as an excess size-having particle-collecting means, a five particle treating means, a rectifying pipe member, a fuffer member and a hindrance and breakage member.

Abstract: The present invention relates to an orthodontic appliance for the treatment of dental malocclusion from the internal sides of teeth, that is, the lingual or palatal side. Brackets are used in the present invention for securing the orthodontic wire, and are provided with grooves so that the orthodontic procedure is carried out by means of the elasticity of the wire. A preshaped orthodontic wire is provided which is arch-shaped along the central incisors, side incisors and canines, linear along the molars and premolars, and where the canines and first premolars meet, it is bent in a crank-shape. Introduction of a crank in the orthodontic wire during manufacture simplifies the orthodontic procedure. Individual slight differences in orthodontic procedure that occur in different persons can be accommodated by slight adjustments of the wire of the invention.

Abstract: The invention is concerned with a magnetically coupled arrangement for a driving and a driven member, which arrangement is operable by a pressure medium and is used in a conveying system. A slidable piston (16) within a tube (10) has an arrangement of annular magnets (20) provided at each end with sealing and sliding members (24, 26). A driven assembly (18) slidable on the outer surface of the tube (10) has an arrangement of annular magnets (32) corresponding to the magnets (20) and provided at each end with a sliding ring (44). The members (24, 26, 44) prevent ingress of foreign bodies to the magnet locations, and consequently enable the spacing between the magnets and the tube (10) to be very small. A good magnetic coupling is achieved resulting in effective transmission of power. Several pistons (16) abutting one another can be used for conveying heavy loads.

Abstract: Individual separated pouches are supplied to the inlet station of an endless continuously-moving carrier provided with adjustable pouch-supporting mechanisms at uniform intervals therealong. Each mechanism supports the pouch adjacent the opposite upper corners thereof. The pouch is moved past an opening station which fully opens the pouch mouth. The pouches are continuously moved through a filling station having plural material-guiding funnels which are rotatably supported and move at the same speed as the pouches when positioned thereover. A control mechanism, synchronized with the pouch carrier, lowers opposed spring-urged fingers into the pouch mouth to center same under the funnel and securely hold same open. Thereafter the guide funnel is lowered into the open mouth and material is deposited through the funnel into the pouch. The funnel and fingers are then raised out of the pouch.

Abstract: A single-acting operating cylinder assembly includes a cylinder and piston of rectangular cross section and a spring arrangement for initially forcing the piston into one operating position. The piston has an axial recess with transverse end walls. A stop block is located within the recess and securable to the cylinder for movement of the piston with respect to the stop block. The spring arrangement is formed by a plurality of side-by-side lying helical compression springs supported between the stop block and the recess end wall opposite the stop block. In one embodiment, the stop block is positioned with respect to the cylinder by an eccentric disk adjustable for adjusting both end positions of the piston in the same direction while retaining a constant piston stroke. In a second embodiment, fixed pins and an adjustable disk connect a modified stop block with the cylinder for adjustability of the length of the piston stroke with one of the piston end positions held constant.
