Abstract: An injection sleeve molding machine having a rubber injection section and a sleeve molding section, in which the sleeve molding section includes a barrel with a mold cavity for receiving uncured rubber material, and two mandrels having a forward and rearward end inserted axially and alternately into the cavity of the barrel for a molding operation. The rear end of the mandrels are mounted on a pivoted member on a carriage which travels parallel to the axis of the mandrels for inserting the mandrels in the cavity of the barrel. When the molding operation has been completed, the carriage withdraws the mandrel from the cavity, and the pivoted member for the mandrels is rotated angularly to place a mandrel in position for insertion in the cavity. When it has been inserted in the cavity, the second injection operation is performed and, while that second operation is being performed, the previously formed molded sleeve is stripped from the first mandrel, thus preparing it for the next succeeding molding operation.

Abstract: A cat box filler system in which two layers of litter are provided in the container in which the material is shipped and sold. The container is provided with a place to be opened when the filler material is to be discharged in a cat box. The layer in the bottom or farthest from the opening in the container contains a substantial amount of odor suppressant and the other layer contains little or no odor suppressant. When the container is to be used the end of the container farthest from the layer with the odor suppressant is opened and the container is held with a hole at the bottom so that the first layer with little or no odor suppressant flows into the cat box, and the layer with the odor suppressant flows over the first layer, forming the top layer of the material in the cat box. The invention also includes the method involving the steps of emptying the container into the cat box to form two layers therein.

Abstract: A gear coupling for a pair of rotatable shafts disposed in end-to-end relation, in which a pair of hubs is mounted on the shafts and sleeves are secured to the inboard side of the hubs and contain internal teeth. A spacer extends between the two sleeves and is provided with gear teeth at each end for meshing with the internal gear teeth in the sleeves. A separate plate is mounted on the inner end of each hub and an element is secured to each end of the spacer for engaging an annular shoulder inside each sleeve, for minimizing the end play of the spacer relative to the hubs and to eliminate or minimize the end play of one shaft by utilizing the stability of the other shaft to control the end play of the first shaft.

Abstract: A clothes drying rack having a vertically elongated cabinet with a rack set disposed in the upper end thereof moveable from a vertical position in the cabinet to a horizontal position extending therefrom. The rack set is disposed in the upper end of said cabinet and is supported by the door when the rack set is moved to its horizontal position and the door is closed thereunder. The rack set includes a plurality of arms pivoted to a fixture and moveable angularly with respect to one another. The drying rack may also include a second rack set disposed in the bottom of the cabinet and moveable from a vertical position to a horizontal position beneath the door when it is closed. The lower rack has a fixture pivoted in the cabinet and a plurality of arms pivotally attached to and extending from the fixture, the arms being adapted to pivot angularly with respect to one another.

Abstract: A variable speed belt drive having a sheave with an axially moveable flange connected to the drive shaft by a flexible element which performs the function of transmitting the torque from the shaft to the axially moveable flange, and which defines a fluid pressure chamber for applying a variable pressure to the moveable flange for moving the flange axially on the shaft as the pressure in the chamber is varied by the operation of a control device. The fixed flange of the same sheave is mounted on a hub and bushing of a flexible coupling connecting the sheave to a drive motor. A belt connects the first sheave to a second variable pitch sheave which is responsive to the load on the drive for maintaining the pitch of the sheave in any preselected position.

Abstract: A modular V-belt sheave which, in a specific embodiment, has two end modules and a hub connected to at least one of the modules and may have one or more intermediate modules and the modules are secured together by a plurality of tying members extending through aligned holes in the modules, the members preferably consisting of cast metal, such as aluminum, with heads on the opposite ends of the elements. The members are cast into the aligned holes and, as the members cool, they contract, holding the modules firmly together. A hub may be used which preferably has a radial member seating between two of the modules and having a plurality of holes for alignment with the holes in the modules and for receiving the tying members so that the members will rigidly secure the modules to the radial member.

Abstract: A brake system for a vehicle in which a pair of brake discs are mounted on two opposed shafts in alignment with one another and pucks are disposed on opposite sides of each of said discs. The pucks between the discs are supported by relatively movable support members, and an adjustment device is disposed between the support members to vary the spacing between the pucks and discs to compensate for wear occurring in the pucks from braking operations. The brakes are operated by a hydraulic actuator which presses the pucks onto the respective discs and urges them toward an abutment, the abutment being either a fixed member or the head of a mechanical brake which can apply a braking force in the direction opposite to the hydraulic actuator, to apply the brakes.

Abstract: A strawberry variety characterized by large plants bearing late-ripening, large fruit.
