Title: Amphoteric ceramic microwave heating susceotor compositions
Inventor: SEABORNE JONATHAN
IPC: B65D81/34
Filed: 1988-04-25
Granted: 1998-12-01
Abstract: Disclosed are improved ceramic compositions which are useful in the formulation of microwave susceptors and to the susceptor articles fabricated therefrom for disposable packages for the microwave heating of food items.  The compositions include a novel microwave absorbing material and a binder.  The novel microwave absorbing materials comprise selected ceramics in both their native and amphoteric forms.  Such ceramics are those with residual lattice charges or an unbalance of charge in the fundamental framework or layers such as vermiculite, bentonite, hectorite, selected micas including Glauconite, Phlogopite and Biotite and mixtures thereof.  These ceramics are activated to their amphoteric form by treatment with either acids or bases.  The compositions provide good heat generation and a predeterminable upper temperature limit which is higher in the amphoteric form than in their native form.  The ceramic materials are common and inexpensive. Preferred compositions additionally include a temperature profile moderator which can be common salt.

Title: Power saving refrigeration device
Inventor: KANN DOUGLAS C
IPC: F25B40/00
Filed: 1988-08-16
Granted: 1992-02-04
Abstract: ABSTRACT OF THE DISCLOSURE      A subcooling condenser/receiver is provided upstream of and proximate to an expansion device in a refrigeration loop, the condenser/receiver having an inlet for receiving cooled refrigerant,  a receiver for accumulating the refrigerant,  an integral suction line to subcool the refrigerant, and an outlet for discharging the accumulated refrigerant to the expansion device.  Because the suction line is integral to the receiver, the cooled refrigerant is in thermal communication with the spent refrigerant. In order to condense and accumulate refrigerant in the receiver the subcooling condenser/receiver has a flow restricting structure which produces a pressure drop between the subcooling condenser/receiver inlet and the receiver.   A liquid seal is formed at the subcooling condenser/receiver in the high pressure line extending from the  compressor to the expansion device.   This arrangement reduces pressure losses in the high pressure line thus  improving the volumetric flow efficiency. Accordingly,  a smaller load is placed on the compressor and the system's power requirements are reduced.

Title: Lighting fixture with diffuser for light and air
Inventor: BURKARTH JACK
IPC: F21V11/00
Filed: 1989-09-28
Granted: 1995-01-03
Abstract: A fixture for a fluorescent lamp includes a diffuser panel.    The  diffuser  panel  has  a  frame  and  longitudinal elements  supported by the frame and spaced apart  from one another.   At least some of the elements are constructed of a material to allow diffusion of impinging light.   Preferred materials  are translucent or transparent,  such as glass or plastic.  The diffuser panel also functions as an air diffuser. Provision of a nozzle in the base of the fixture allows air to flow through the panel by a sucking effect created by high velocity forced air flowing through the nozzle.  This results in fixture cleaning and temperature equalization.  The fixture is particularly adapted to be mounted in a moving vehicle.  For this purpose, the panel is designed to be tamper-resistant and to provide easy maintenance.  The diffuser panel, when a latch is opened, may be lowered by rotation to provide access to the lamp and ballast. When the fixture is installed in a public vehicle, a handrail is provided which forms part of the panel lowering  mechanism.    Other  arrangements  provide  a  fixture having a diffuser with a central open portion and a pair of side panels extending across the ceiling of a vehicle.  A pair of nozzle elements are disposed above each side panel.  Again, high velocity air directed through one portion of a nozzle element will cause air to be drawn through the open central portion of the fixture.  Either the entire diffuser or the side panels may be lowered to clean the fixture or replace the lamps.
