A phototherapy device includes a clothing item. Illuminators are secured to the clothing item and arranged to illuminate at least a portion of a patient wearing the clothing item. The illuminators include light emitting diodes (LEDs) mounted on at least one flexible printed circuit board (PCB). A temperature sensor is secured to the clothing item and positioned to measure a temperature proximate to the patient wearing the clothing item. A control circuit is connected to receive the temperature from the temperature sensor and operative to turn off the illuminators responsive to the temperature exceeding a maximum permitted temperature.

A temperature control system and a thermal valve for said system composed of a housing having a gas inlet port connected to the refrigerant return line and a gas outlet port disposed in a compressor interior. A helical thermostat metal coil is fixed within and at one end of the housing, the other end of the coil being free to rotate with change in temperature. The thermostat metal for the coil is preferably chosen so that no movement thereof takes place until some predetermined temperature is reached, at which temperature rotation of the free coil end commences. The free coil end, either along or in conjunction with a baffle or the like, normally blocks the gas inlet port and prevents refrigerant gas from entering the housing and passing therethrough onto the compressor motor. When the motor within the compressor heats up to the predetermined temperature, the thermostat metal helical coil proceeds to rotate and moves the end thereof or baffle attached to the end thereof away from the gas inlet port and permits refrigerant gas to enter the housing and pass therethrough to cool the motor therein. When the motor within the compressor is cooled below the predetermined temperature, the thermostat metal coil will have rotated in the opposite direction to again close off the fluid inlet port. In this way, the refrigerant gas is applied to the compressor motor only under conditions of overheating.

A motor protector having a can and internal electrical contact is hermetically sealed to a disk-shaped header of conductive material having a flattened edge for orientation during fabrication with spaced conductive pins sealed in and insulated therefrom. A heater-support with holes for fabrication is bonded to one conductive pin, a bimetallic element parallel to the axes of the pins having a contact element normally contacting the can contact. A heater without right angle bends is bonded to each of the electrically conductive pins, is spaced from the movable contact and rests parallel to the axes of the conductive pins. The motor protector is fabricated by providing a fixture having two depressions, one somewhat in the shape of the movable contact with upwardly extending pins for mating with the support apertures therein and the second for receiving the header in an upright position and adjacent the first. The support is placed on the fixture with the pins extending therethrough for support orientation. The header is then oriented in its fixture depression with one of the pins through the header resting against the support and is bonded to the support. The movable contact is then disposed in the proper depression and welded to the support. Slider brackets then receive the heater thereon and position it on the pins to which they are secured. The formed motor protector portion is placed in the cans and hermetically sealed thereto with the contact within the can disposed against the contact element on the movable contact member.

Hermetic motor protector

A motor protector having a can and an internal electrical contact is hermetically sealed to a disk-shaped header of conductive material, the header having a flattened edge for orientation in the can during fabrication of the protector and having spaced conductive pins sealed in and insulated from the header. A heater-support having holes for fabrication is bonded to one conductive pin, a bimetallic element on the support has a plane parallel to the axes of the pins and has a contact element normally contacting the can contact. A heater is bonded to each of the electrically conductive pins spaced from the movable contact and in a plane parallel to the axes of the conductive pins. In making the motor protector a fixture has one depression with pins mating with the support apertures and has a second depression receiving the header in an upright position and adjacent the first depression. The support is placed on the fixture with the pins extending therethrough and the header is oriented in its depression with one of the pins header resting against the support and is bonded to the support. The movable contact is disposed in its depression and welded to the support. Slider brackets receive and position the heater on the pins to which they are secured. The formed motor protector portion is placed in and hermetically sealed to the can with the contact within the can disposed against the contact element on the movable contact member.
