Abstract: A daycare sleeper includes a mat, a pillow, detachable blanket that is non-confining, and an integral storage pouch. The preferred storage pouch is a pocket generally equal in width to the sleeping pad and is located at or near the foot of the sleeping pad on the top surface of the sleeping pad. The storage pouch may be used both as a foot pocket for the person resting on the sleeping pad and as a container for the pad and blanket during non-use. The storage pouch opens toward the top end of the sleeping pad and is closed on the other sides, so that the sleeping mat and blanket may be rolled together from the head of the sleeping pad toward the storage pouch and into the storage pouch. The preferred blanket attaches to the sleeping pad at or near the open end of the storage pouch, is loose on the sides, and is removable. A handle may be positioned on the outside of the pouch for easier carrying.

Abstract: A lip seal comprises resilient annular sealing means 2, 3, having a sealing lip 4 adapted for sealing engagement at an end 9 thereof with a relatively movable shaft and a valve lip 6, the lips being, in use, normally closed, and means 11, 13, for injecting fluid into a space 7 between the closed lips 4, 6 at sufficient pressure to cause the lips to open during use to allow the fluid to flow towards the end 9 of the sealing lip 4.

Abstract: In order to facilitate the formation of a plastic member with an aperture in a central portion thereof, a ring gating valve arrangement is provided with a multi-piston servo arrangement which enables a specially configured pin to be stepwisely reciprocated back and forth within a molding device. The pin is formed with a land at one end which is dimensioned and shaped to produce the required aperture. The pin further features a channel structure which includes an annular recess adapted to permit plastic to flow into the center of the mold cavity area when the pin is thrust to a predetermined location. After the cavity is filled with hot plastic, the pin is retracted to a position wherein the annular recess is located within a removable gate bushing and the shaped land is pulled up until it is appropriately located in the mold cavity area. As the injected plastic cools and solidifies, the shaped land acts as the aperture molding pin and forms a clean aperture in the molded part.

Abstract: A display and storage holder for tape cassettes is made up of at least one box-like housing having opposite side, top and bottom walls and a back panel, and being open at the front for receiving therethrough a plurality of the tape cassettes, connectors removably extending across at least the side walls of each housing and each having front and back end portions engageable with the housing for securing the respective connector thereto, a door panel separate from each box-like housing and having side edges and top and bottom edges dimensioned to extend across the front of the housing, dimples in the front end portions of the connectors extending across the side walls, ball-shaped projections on the door panel adjacent one of the side edges and which are relatively tightly engageable in the dimples on the connectors extending across the adjacent one of the side walls for defining a hinge for the door panel, and ball-shaped projections on the door panel adjacent the other of the side edges and which are relative

Abstract: A method and system for the contemporaneous delivery of data from a first location to a user at a remote location utilizes standard broadcast facilities as the transmission medium. The data and an identifier uniquely associated with the data are encoded and transmitted along with a first standard broadcast signal. An enabling cue signal corresponding to the identifier is encoded and transmitted along with a second standard broadcast signal. The first broadcast signal is received and demodulated at the user location, the identifier is decoded and the encoded data is stored in a memory location uniquely associated with the identifier. The second standard broadcast signal is also received and demodulated at the user location and is decoded to provide the cue signal. The cue signal is compared with the received identifier and if the comparison is positive the stored encoded data is recalled from the memory, decoded and printed at the discretion of the user.

Abstract: A position detector to detect the fully open position of a valve gate pin in a gate valve controlling the flow of molten plastic material to a die cavity includes a sensing member which has a DC voltage impressed thereon and which is electrically isolated from the valve gate assembly. An extension of the valve gate pin contacts the sensing member when the valve gate pin is in its fully open position to short the impressed voltage and thereby indicate a fully open condition.

Abstract: A needle threading device comprising a flashlight having a needle mounted on the side of the flashlight with the eye of the needle projecting above the lens of the flashlight. A magnifying glass has its handle mounted on the opposite side of the flashlight with the magnifying glass also extending above the lens of the flashlight. The axis of the magnifying glass coincides with the axis of the eye of the needle.

Abstract: A mining machine suitable for cutting roadways in coalmines comprises a cutting head, a conveyor for moving mined material rearwardly of the machine and a discharge conveyor for unloading the mined material to one side of the machine. As the machine advances the discharge conveyor can be used selectively to unload coal onto a stage loader and other material into packholes, thereby saving labor. The discharge conveyor may be pivotable about horizontal and/or vertical axes, longitudinally extendable or movable relative to the machine or cutting head to obtain maximum control over the area in which it discharges material.

Abstract: A dust control mat having a pile fabric upper surface and a bottom calendered rubber stock sheet which employs an anti-tear strip located perpendicular to the grain or calendered direction of the rubber stock sheet between the rubber sheet and a latex backing on the pile fabric. A novel method is employed to produce the mat in which the reinforcing tear strip is located in position prior to vulcanizing the rubber stock sheet in an autoclave.
