  • Publication number: 20170260638
    Abstract: A method for manufacturing a composite part of polymer and metal utilizes a mold having a plurality of mold parts and forming a layer of metal on at least one inner or cavity-facing surface of the mold. Thereafter the mold parts are assembled to one another to form a mold cavity defined in part by the layer of metal. The mold cavity is then filled with resin material so that the resin material is in contact with the layer of metal. A curing or hardening of the resin material in the mold cavity is followed by an opening of the mold and the removal of a composite part having a metal shell or outer layer and a polymeric backing or inner layer.

  • Patent number: 9445877
    Abstract: A toothbrush has a frame, a bristle holder movably mounted to a distal end of the frame, and a power transmission assembly operatively connectable to a drive motor and operatively connected to the bristle holder so as to move bristle tips on the bristle holder along an oval path relative to the frame. In a single cycle of movement along the oval path, the bristles shift away from the frame and towards the teeth, then along and in contact with the teeth in a direction away from the gum line, then back towards the frame and away from the teeth, and subsequently along the frame and out of contact with the teeth.

  • Patent number: 8803682
    Abstract: In a system for protecting a user from injury sustained during sleep, a sensing device is operated to automatically monitor orientation or posture of a user during sleep of the user. A signal is transmitted from the sensing device to a control unit, which is operated to activate an appliance so that the appliance generates an alert signal upon detection by the sensing device and control unit of an undesirable orientation or posture of the user.

  • Publication number: 20120137444
    Abstract: An adjustable contour mattress is provided with a multiplicity of zones each having a mattress height independently adjustable by a respective electro-mechanical actuator. The actuators are disposed within the mattress between a lower panel member and an upper mattress layer. A control unit is connected to the actuators for operating them to alternately raise and lower respective zones of the upper mattress layer. A remote control is operatively connected to the control unit and includes command input elements enabling an individual user to selectively operate the actuators independently of other ones of the actuators, whereby the user can adjust heights of the zones independently of one another.

  • Patent number: 7172721
    Abstract: The invention provides a novel thermoplastic molding process useful in the manufacture of hollow, deformable thermoplastic articles such as hollow doll heads. In the process of the instant invention, a parison is formed at a first injection station and is transferred to a blow mold station. At the blow mold station, the parison is transformed into a hollow, deformable thermoplastic article through application of a vacuum and gas injection. Articles made by the process of the instant invention have a highly realistic appearance and texture.

  • Patent number: 5794296
    Abstract: An electric toothbrush is disclosed having a power driven rotary brush in which the direction of rotation of the brush is automatically controlled depending on whether the top or the bottom teeth are being brushed in order to brush any food debris present on the teeth and gums in a direction away from the gums. The toothbrush of the present invention utilizes a direction controller that is placed inside the mouth between the top and bottom teeth. The direction controller controls the direction of brush rotation and serves to stabilize the toothbrush relative to the teeth during the brushing operation. The movement of the direction controller operates a reversing switch to change the direction of rotation of the brush as required to brush in a direction away from the gums and towards the teeth without removing the toothbrush from the mouth.

  • Patent number: 4221454
    Abstract: A battery box, particularly for use in toys, is capable of establishing electrical contact with battery terminals. The battery box includes a housing which bounds a compartment for accommodating at least one battery, but preferably a plurality of batteries therein. A pair of contact members is provided for the battery or each of the batteries, each of the contact members having a contact portion located in the compartment and adapted to contact one terminal of the battery. A mounting portion of one of the contact members of the pair is slidably received in an opening of an end wall of the housing and a leaf spring biases the contact member towards its extended position in which a contact portion of the contact member contacts and presses against one terminal of the respective battery. The leaf spring is located adjacent the surface of the end wall which faces away from the compartment. The slidably mounted contact member is plate-shaped and the opening of the end wall has a corresponding configuration.

  • Patent number: 4003158
    Abstract: A fighting doll has a lower torso and an upper torso having freely movable arms rotatably mounted thereto. Actuating means within the doll when actuated causes the upper torso to pivot relative to the lower torso and simultaneously swings one arm upward and the other arm downward from a resting position in a fighting motion.In one embodiment, the actuating means is activated by a push button extending from the lower torso. The upper torso is pivotably secured to the lower torso and to a central shaft which is fixedly mounted to the lower torso. A stationary cup gear is positioned on the central shaft and is in communication with arm pinions secured to shafts extending from each arm. The push button has a rack formed at its end which is in communication with a pinion rotatable on the central shaft. Fixed to the pinion is a sleeve which is secured to the upper torso. By depressing the push button, the pinion and sleeve rotate on the central shaft causing the upper torso to pivot.
