Abstract: An article retention apparatus includes a roller conveyor unit with a plurality of rollers arranged in a horizontal plane and a plurality of ladder-shaped rack units on which articles rest. The roller conveyor unit and rack units are configured such that the rack units may be moved above and below the plane of the conveyor unit rollers without interference between the conveyor unit rollers and the rack units. By lifting the rack units one by one from below the roller plane to emerge above the roller plane, the article is transferred from the roller conveyor unit to the rack unit. The articles are taken aside of a transport system and temporarily retained by the apparatus. A belt conveyor unit can be used instead of the roller conveyor unit.

Abstract: A brake apparatus applies a braking force from a stationary member to a moving member adapted to move relative to the stationary member. Magnets are arranged on the stationary member along the linear motion or rotational direction of the moving member and magnets are arranged on the moving member so that the stationary side magnets face the moving side magnets. When magnetic attractive/repulsive forces between the magnets on the moving and stationary members act in a direction to accelerate the moving member, the magnets on either one side are allowed to escape in the same direction. When magnetic attractive/repulsive forces act in a direction to decelerate the moving member, the magnets are restrained from movement in the same direction. This brake avoids any temperature rise due to local heat generation during braking.

Abstract: The invention provides a spring rod for a strap. A stationary member with a projection is inserted and fixed at one end of a cylinder with a longitudinal slit. A slider is slidably inserted in the cylinder with a spring interposed between the slider and the stationary member. The slider has a projection which has a tongue protruding through the slit of the cylinder.

Abstract: This invention provides a process for preparing artificial leather bands or belts, particularly those suitable for use as watch bands or straps which are characterized by bearing close resemblance to natural leather in the appearance, feeling and touch and toughness of the product, inexpensive production cost and easiness in the production control.

Abstract: A controlling apparatus for the driving gear of a suction cleaner equipped with a container accommodating a suction fan together with a motor for actuating said fan, a suction hose, and a device for the paying-out and hauling-in of said suction hose together with a reversible motor for actuating said device, both of said motors being supposed to be controlled by means of controlling circuits to be actuated by a switch disposed near the fore end of said hose through a couple of lead wires buried in the hose, wherein said controlling circuits for these motors are respectively provided with three relays for actuating the respective motor and three switches for actuating said relays as incorporated therein, two of three circuits thus combined with said relay and actuating switch corresponding therewith are respectively provided with AC half-wave rectifiers having opposite polarities while the remaining one circuit is provided with contacts to be controlled by two relays included in said two circuits.

Abstract: A suction cleaner, wherein the interior of a container thereof is divided into two chambers, namely, the first chamber and the second chamber, by a partition, and the first chamber accommodates a suction fan, a filter member and a dust-receiving box installed therein while the second chamber randomly stores a suction hose, the rear end of said hose being rotatably supported within an opening provided in said partition while the front end of said hose projects out of an opening provided on one side of said container; a device for the paying-out and hauling-in of the hose is installed adjacent the inside of said opening provided on the container; lead wires are provided for the hose along the whole length thereof, the front end of said lead wires being connected with a switch mounted on the hose while the rear end of the same being connected with a ring contact provided on the hose; said movable contact is devised to be in touch with a fixed contact provided on the partition; and said fixed contact is connected
