Title: Integrated circuit package and compact assemblies thereof
Inventor: TAI KING L
IPC: H01L25/04
Filed: 1991-07-04
Abstract: An integrated circuit package comprises a thermally conductive plate for receiving an integrated circuit and an open rectangular structure of conductor and insulator for surrounding the sides of the circuit and presenting one or more linear arrays of conductive connectors extending laterally through the rectangular structure. Preferably the rectangular structure also includes transverse contacts. Advantageously the plate includes extensions beyond the rectangular structure for acting as cooling fins on opposing sides of the rectangular structure. The linear arrays and cooling fins are preferably on different pairs of parallel sides. The integrated circuit package permits the aggregation of packages into assemblies and into clusters of assemblies rich in interconnections. Vertically stacked packages form a rectangular parallelepiped having a plurality of parallel planar cooling fins projecting from two opposing surfaces and another pair of planar surfaces providing rectangular arrays of contacts to the enclosed integrated circuits. In addition, transverse contacts permit electrical interconnection of the stacked packages. Linear clusters can be aggregated as a linear array of such assemblies with their contact surfaces interconnected either directly by an anisotropically conducting plane or indirectly by an intervening transformation plane. In a preferred linear cluster, successive assemblies are rotated by 90° with respect to the axis of the array. In such clusters each package in the rotated assembly contacts each package in the neighboring assemblies. In low power equipment, elimination of the cooling fins permits even higher levels of interconnection such as rectangular clusters of assemblies.

Title: Method for detecting and correcting reversing valve failures in heat pump systems having a variable speed compressor
Inventor: DUDLEY KEVIN F
IPC: G05D23/19
Filed: 1991-07-31
Abstract: METHOD FOR DETECTING AND CORRECTING      REVERSING VALVE FAILURES    IN HEAT PUMP SYSTEMS HAVING A VARIABLE SPEED COMPRESSOR               ABSTRACT OF THE DISCLOSURE            Temperatures in the inside heat exchanger or both the inside and outside heat exchangers of a reversible vapor compres-sion refrigeration system are sensed before and after a system startup or mode change.  If the reversing valve is positioned properly, the temperatures should change in a certain way because of the operating change, e.g., on a startup in cooling mode, the inside heat exchanger tempera-ture should decrease.  If the temperatures actually sensed do not change in the predicted way, it is an indication that the reversing valve is incorrectly positioned for the operating mode selected.  If the temperature changes indi-cate that the reversing valve is out of position, the variable speed compressor is operated at its maximum speed for a short time.  If the temperature change is now as expected, the valve has changed to the proper position.  If the temperatures still have not changed in the way predict-ed, the reversing valve is still improperly positioned.          This indicates a malfunctioning valve and the system is shut down.

Title: Luggage alarm foot
Inventor: JICKLING LES J
IPC: G08B13/14
Filed: 1992-01-06
Abstract: Abstract:             "The Luggage Alarm Foot" is a simple device designed to prevent the theft of idle luggage left unattended within earshot of the owner. This device would be most useful on second class sleeper trains, station luggage racks, airport lounges etc., or anywhere that luggage is not given immediate attention. The device is weight activated and secured as a foot to the luggage, such that anyone attempting to lift (i.e. remove surreptitiously) without first activating the override switch, would cause a high pitched electronic alarm to sound. The override switch would turn the alarm off at the owner's convenience to prevent unwanted sounding of the alarm (i.e. when the owner wishes to move the luggage), this same override switch would then be used to reactivate the alarm when left temporarily unattended. A spring loaded switch which when depressed by the weight of luggage is in the "off" position, but which with the removal of weight becomes engaged to the "on" position, would be the alarm trigger mechanism. Independent of the override switch, the spring loaded trigger switch would thus rest in the "on" position, and be shut "off" only with the weight of the luggage. (i.e. or of course with the override switch) The alarm would be of the small electronic variety powered by a dry cell battery.

Title: Compact liquid reservoir and metering apparatus
Inventor: SMITH TIMOTHY J N
IPC: G01F11/02
Filed: 1992-05-13
Abstract: Abstract A reservoir system and metering apparatus for dispensing liquid under pressure at a regulated rate.  The reservoir includes a resilient material walled container with sheet spring means which act on the walls of the container resiliently pressing them to reduce the internal container volume and to exhaust liquid from the container thereby.  The sheet spring means is prestressed by initial preforming in relaxed condition and the sheets are then rolled together and secured at their edges to exert continuous pressure on the container.  A hinged clip arrangement for the sheet springs is described as well as the initial preforming of the springs to a substantially semi-elliptical profile.  In some instances the sheet springs adopt a planar form in the empty condition of the bag.  In other instances the sheets are circular arcuate in that condition. Metering means for the reservoir is a capillary tube, a set of capillary tubes, a multiple orifice, a variable orifice including one with pressure regulating means, or a sequenced valve assembly which makes use of a metering chamber.

Title: Method and apparatus for dispensing a fluidic media onto a selected region of a workpiece
Inventor: KOVALETZ MARK P
IPC: B05B15/68
Filed: 1990-11-19
Abstract: A rigid stabilizer bar (36) is suspended from a quick-release cargo hook attachment point (14) of a helicopter, and a yoke structure (44) is releasably carried by the hook (12) in fixed relation to the bar for suspending a load (32), opposite ends of the yoke having flexible lines (58) connected to spaced apart locations (60) on the load. Opposite ends of the stabilizer bar are connected by bungee cords (40) to landing skid anchors (42) for stabilizing the yoke. The load is oriented by yawing and rolling maneuvers of the helicopter. In an emergency, the yoke, together with the lines and the load, can be jettisoned from the vehicle by releasing the hook. The load can be a dispensing module (70) for directing a fluidic medium such as crushed walnut shells in high-pressure air blast from a nozzle (94) that is located on a boom (96) projecting from the module, onto an elevated workpiece (76) such as an insulator of a transmission line tower (72) for cleaning the insulator. The cleaning module produces a stream (104) of particulate. The helicopter can fly with the module suspended beside the insulator, the nozzle being aimed relative to the workpiece horizontally by yawing the helicopter and vertically by rolling the helicopter. The nozzle is also movable, and the boom can be raised and lowered by remote control for effective access in a variety of workpiece configurations. The module also generates foam for fighting fires.
