  • Publication number: 20090110029
    Abstract: A temperature probe, such as for a respiratory system in which breathable gases are supplied to a patient, includes a housing having an external wall and an internal cavity defining an end and an internal cavity and further includes a temperature-responsive device in an area of the cavity near the end, such as in thermal communication with the external wall. A first potting compound that is deformable and/or has a relatively high thermal conductivity holds the temperature-responsive device in the cavity and a second potting compound having a relatively low thermal conductivity may be in the cavity behind the first potting compound. The housing may be made thin to enhance thermal conductivity, at least in the area containing the temperature-responsive device.

  • Publication number: 20090110378
    Abstract: A temperature probe, such as for a respiratory system in which breathable gases are supplied to a patient, includes a housing having a cavity sized to snugly receive therein a generally cylindrical container within which is secured a thermistor, with the container adapted to provide a barrier to moisture. The probe provides a quick temperature response but minimizes migration of moisture to the thermistor notwithstanding the high temperature and heat levels encountered in normal operation of the respiratory system.

  • Patent number: 7120967
    Abstract: A pet door hinge adapted to accommodate potentially damaging forces. The hinge mechanism includes a shaft that is received by a shock-absorbing bearing. The bearing is received by a sleeve. The bearing rotates within the sleeve to allow pivoting of the flap. In the event of potentially damaging forces, a resilient and deformable material forming the core of the bearing gives to prevent damage to or destruction of the hinge mechanism or the pet door.

  • Patent number: 6959511
    Abstract: A pet door offering ingress or egress through a structural member. A lock mechanism in the pet door allows the pet owner to restrict ingress and/or egress as desired. The pet door features a dual control system that simplifies the setting of the lock. Each control corresponds to movement of the flap in one direction. The dual control system is also designed to be easier to access than a conventional pet door lock mechanism and to be less susceptible to unintentional adjustment resulting from incidental contact with the controls.

  • Patent number: 6477807
    Abstract: A door hinge system and door assembly allow a door in a wood veneer dryer to be pulled directly away from its associated door frame before being allowed to swing open in the normal fashion, thus reducing wear on the seal between the door and the door frame. The door assembly allows the tightness of the door to be easily adjusted without the need for shims, and allows the tightness to be adjusted even when the dryer is in operation.
