Title: Apparatus for the sensing of refrigerant temperatures and the control of refrigerant loading
Inventor: GREGORY CHARLES
IPC: F25B5/02
Filed: 1989-11-29
Abstract: Abstract of the Disclosure A new device is provided for sensing refrigerant temperatures in refrigerator systems, and for the control of refrigerant loading in a plurality of refrigerator evaporator circuit coils connected in parallel.  Such evaporator coils are supplied with refrigerant through a thermostatically controlled flow control valve, which is controlled by a sensor to ensure a predetermined amount of superheat.  The usual minimum superheat is about 5.5°C (10°F) and to reduce this value the refrigerant is passed through the device in which it is rendered thoroughly turbulent and mixed, the device intercepting the entire refrigerant flow just before the sensing of the superheat, thus ensuring that the temperature is accurately measured.  In one aspect of the invention the device consists of a series of three chambers connected together by two similar sets of holes, the first and third chambers being similar so that it is completely reversible.  In another aspect of the invention the part of the device wall intended to receive the sensor is provided with a groove into which the sensor fits snugly to increase the heat exchange contact between them.  Grooves of different sizes can be provided in the same device.  The heat conductive contact can be increased further by sandwiching a layer of pasty heat conductive material between the sensor and the groove wall that fills the space between them.

Patent CA-2014320-A1 (CA)
IPC: B65D6/12
Filed: 1990-04-10
Abstract: ABSTRACT OF THE DISCLOSURE    A dental floss holder is in the form of a box with a drawer in it.  The bottom of the drawer includes a hub which is spring biased to push a bobbin mounted thereon toward an opposite side of the box.  The bias is such that the bobbin drags with a predetermined force on an opposite side of the box to maintain tension in the floss.  A result is that the bobbin does not unwind while in the holder, thereby precluding a snarled floss line.  Also, the tension gives a smooth "pull" which adds a "feel" of quality to the floss.  The "feel" does not change as the diameter of the bobbin changes with either an exhaustion of floss or changes in the diameter of a full bobbin.  The hub is mounted on a dome having sides with a shape which guides and directs any floss falling off the bobbin back onto it.
