Abstract: A perch for infants or handicapped persons employs a support member which is designed such that an individual can be laid on it in a prone, generally fetal-like position. The support member has an upper end adapted to support the individual's head such that the head can be picked up and moved from side to side, a lower end adapted to support the individual's buttocks and a midsection adapted to support the individual's trunk. Cutouts in the midsection near the upper end of the support member permit the individual's arms to hang freely on opposite sides of the support member. Similarly, cutouts in the midsection near the lower end of the support member permit the individual's legs to hang freely on opposite sides of the support member. A base positions the support member above a support surface such that the individual's legs and arms are freely suspended above the support surface. By interchanging various different bases, the perch can be converted into a rocker, a car seat, a swing or a stroller.

Abstract: A game makes use of top-like game pieces in order to test the manual dexterity and mental acuity of a player who must keep as many game pieces as possible spinning simultaneously on a playing surface. The game pieces are spun by twirling them between the thumb and finger of the player, who then projects them onto the playing surface as they continue to spin. In playing the game, the period of play can terminate upon the expiration of a preselected length of time or when one of the game pieces stops spinning or after a predetermined number of game pieces have been put into play.

Abstract: A garbage disposal unit is treated by a device which, in response to the activation of the garbage disposal unit, is propelled against a wall of an interior chamber of the unit. Due to its natural elasticity, the device ricochets off of the wall, thereby randomly striking and treating a plurality of areas on the wall. Ingredients, such as detergents, degreasers, scouring agents, disinfectants, foaming agents, sterilizers, etc., can be added to the device prior to or during operation in order to facilitate such treatment.

Abstract: Polygonally-shaped blanks useful in making products such as can parts are formed by dividing a relatively wide web of material into a plurality of relatively narrow strips, each strip having longitudinal edges delimited by scroll lines formed from a plurality of straight scroll line sections. The strips can be arranged parallel to a longitudinal axis of the web or at an angle relative thereto. It is also possible to divide the strips into individual blanks at a scrolling station or at a remote can making station. The polygonal shape of the blanks permits them to be designed so as to compensate for earing caused by the anisotropy of the material from which the web is made. Various punches and slitting arrangements can be employed to perforate the web and to longitudinally and laterally cut it so as to form the strip and/or blanks therefrom.

The skimmer is also provided with isolating means for isolating the entraining stream of water from the rest of the water flowing through the skimmer. The isolating means includes actuating means for selectively actuating and deactuating the isolating means such that the skimmer can be operated at a normal flow rate when the isolating means is actuated and at an increased flow rate when the isolating means is deactuated.

Abstract: Disclosed herein are a method for removing liquid from a permeable material, such as slurries, sludges, porous solids and permeable foams. The method involves constraining the material to be deliquified such that the material interfaces with at least one surface which is permeable to the liquid to be removed and then heating the material at one or more locations remote from the permeable surface or surfaces. Such constraining and heating of the material causes the in situ vaporization of the liquid in the vicinity of the remote location or locations. The vaporized liquid expands and forces at least some of the remaining unvaporized liquid through the permeable surface or surfaces.

Abstract: A coupling sleeve (3) pushed onto the plastic pipe (1) and provided with barbs (3a) is drawn over a driving shoulder against the connecting piece (2) by a union nut (4). The opened-out pipe end (1a) is clamped between a curved end face of the connecting piece (2) and the coupling sleeve (3). Possible leakages caused by the flow of the pipe material are prevented by a spring (6), and the pipe (1) is prevented from turning during assembly by a sliding ring (5). The device used for assembling the pipe connection has grips (13) for fixing the pipe in position with a toggle lock (16) and a press ring (26), which can be displaced in sliding manner on a stop (25) acting as a centering arbor, and can be actuated by a hand lever (31). With only a few manipulations, the coupling sleeve (3) can be pushed onto the centrally held plastic pipe (1).

Abstract: A pendulum frame (2) is suspended on a fixed stand (1) by means of four pendulums (16). The amplitude of each of the pendulums (16, 17) is limited by a plate (24) provided with an orifice (23). The plates (24) carry locking projections (28), into which detent pawls (26), arranged on the pendulum frame (2) can engage. When only one of these detent pawls (26) is in the locking position, the bedding furniture can swing about this detent pawl which functions as a pivot pin. When two detent pawls (26) located behind one another in the longitudinal direction of the bedding furniture are locked, the pendulum frame (2) is blocked and is held outside its mid-position on one side. A free-swinging mid-position, four pendulum positions locked at one point and two fixing positions locked off-center are therefore available for each piece of bedding furniture.The bedding furniture can be adapted to meet individual sleeping requirements and is also characterized in that bed care becomes considerably easier.

Abstract: A device for interconverting rectilinear and rotary motion is designed so as to reduce side thrust exerted on a frame by a slide as the slide reciprocates linearly relative to the frame and such rectilinear motion is converted into the rotary motion of a crank or vice versa. More particularly, an elongated opening, which receives a crankpin of the crank such that the crankpin moves back and forth along the elongated opening, is provided in a swing mounted for oscillatory movement relative to the slide. At least one arm is pivotally attached to the frame and to the swing so as to effect the oscillatory motion of the swing relative to the slide as the slide reciprocates relative to the frame. As the slide reciprocates relative to the frame, the orientation of the elongated opening relative to the slide is constantly varied.
