Title: Interconnecting structure for releasably securing successive panels in a relocatable wall
Inventor: JACKSON FRANCIS G
IPC: E04B2/74
Filed: 1990-05-28
Abstract: ABSTRACT OF THE DISCLOSURE The present invention is directed to an interconnecting structure (10) for a relocatable wall. The successively adjacent wall panel assemblies (11) arejoined in a linear intersection (12) by a cam key block (35) secured to the vertical frame members (21) of the successive wall panel assemblies (11A and 11B). Cam surfaces (55) and lateral locators (65) are presented from the cam keyblocks (35). The lateral locators (65) are of such configuration that when the cam key blocks (35) are disposed in opposed pairs, the lateral locators (65) effect lateral alignment of the cam key blocks (35), A cam key (75) presents at least two pair of locking bolts (80 and 81) which extend transversely outwardly from said disk portion (78) of the cam key (75). The lock bolts (80 and 81) are disposed in diametric opposition and are complementary to the cam surfaces (55) on the cam key blocks (35). The cam key (75) is rotatable with respect to the cam key block (35) selectively to position the locking bolts (80 and 81) in engagement with the cam surfaces (55) on the cam key blocks (35). The present invention cam also be employed to join converging wall panel assemblies (11) by the interposition of post arrangements (20) which are adapted to present the requisite cam key blocks (35) for interaction with the cam key blocks on the wall panel assemblies (11). An alternative cam key block (125) is also disclosed, and a variation of the cam key block concept is incorporated in the end cap clip (155).

Abstract: ABSTRACT OF THE DISCLOSURE        A  compact,  high efficiency  heat  exchanger  for a fuel-fired forced air furnace has horizontally spaced apart inlet   and   outlet   manifold   structures   which   are innerconnected by a horizontally spaced series of vertically serpentined, relatively small diameter flow transfer tubes.          Larger diameter inlet flow tubes are positioned beneath the balance  of  the  heat  exchanger,  extend  parallel  to  the transfer tubes, and have upturned discharge ends connected to the underside of the inlet manifold.  The heat exchanger is configured so that its total vertically facing peripheral surface  area  is  considerably  larger  than  its  total horizontally   facing   peripheral   surface   area,   thereby significantly reducing undesirable outward heat loss through the vertically  extending furnace housing  side walls upon burner shut off and increasing the overall efficiency rating of the furnace.   To reduce the manufacturing cost of the heat exchanger its components are assembled using a weldless fabrication process which includes swedging the tubes to the manifolds and forming each manifold from two sections which are edge rolled and crimped together.

Title: S02 control using moving granular beds
Inventor: DOWNS WILLIAM
IPC: F23J15/02
Filed: 1990-12-28
Abstract: A method and apparatus of scrubbing acid gas from flue gas comprises slats which define a moving bed of scrubbing material which is capable of reacting with the acid gas to form reaction products on particles of the scrubbing material. Flue gas from a boiler or other sources of flue gas is passed through the moving bed of scrubbing material. The scrubbing material is sprayed with water to the. saturation point for increasing the rate of reaction between the reaction gas on the scrubbing material. The scrubbing material leaving the bottom of the moving bed is subjected to a separation step which removes the reaction products as fine dust which is discarded, and returns the now regenerated particles of scrubbing material to the top of the moving bed.

Title: Particulate trap regeneration apparatus and method
Inventor: BAILEY JOHN M
IPC: F01N13/02
Filed: 1990-08-13
Abstract: Abstract of the Disclosure Particulate Trap Regeneration Apparatus and Method Prior art trap regeneration devices employ one or two relatively large ceramic trap cores, and a regeneration cycle that burns off the soot in a direction that subjects the porous walls to excessive temperature spikes.  Moreover, during regeneration it is normal to bypass dirty exhaust gas directly to the atmosphere.  In a first embodiment the subject trap regeneration apparatus (10) includes an electrical heating element (82) and a reverse flow device (92) for each of a plurality of relatively smaller trap cores (61) arranged in a housing (12), with each reverse flow device (92) constructed for directing a source of air (180) at a controlled rate toward the normal second end (63) of the trap core (61), heating the air, forcing the heated air through the trap core (61) to the first end (62), and to controllably burn out particulate matter while the remaining trap cores (61) are functioning to filter the exhaust gases in the normal flow direction.  In a second embodiment a heater and reverse flow device (226) is movably positioned before a selected one of the smaller trap cores (61') and a reverse flow burnout method employed similar to the first embodiment.  Preferably, the reverse flow device (92,226) includes a choking orifice (112) for controlling the rate of flow of the air to the selected trap core (61).

Title: Positive displacement pumps
Inventor: BARAN MARK E
IPC: F04C14/28
Filed: 1991-12-23
Abstract: ABSTRACT OF THE DISCLOSURE    Improvements in screw pumps, and especially positive displacement pumps, are disclosed.   The clearance between the screw flight and the bore is increased over an increased period.  The screw is balanced at preferred locations on the flight.   Wear hard material such as tungsten carbide is emplaced on a portion of the outer surface of the screw flight.   A wear measurement port extends from the outside surface of the pump to the inner surface of the bore. Pressure regulating ports and controls provide an active pressure feedback control system to control the feeding of pressure from the outlet end of the screw back toward the inlet end of the screw.  Pump wear, and pressure pulsations in the operation of the pump are thus reduced.   The wear measurement port enables a method of monitoring wear on the pump screw during operation without disassembling the pump, namely by manipulating a wear measurement device through the port.  The wear measurement device can be a proximity sensor which can be connected to a monitor.  The wear measurement port can be sealed with the proximity sensor in place in the port, such that wear of the screw can be monitored while the pump is operating.

Title: Air booster for deflated pneumatic tires
Inventor: PASS JOHN
IPC: B60C29/06
Filed: 1992-06-11
Abstract: ABSTRACT OF THE DISCLOSURE   The  "AIR  BOOSTER  FOR  DEFLATED  PNEUMATIC  TIRES"  is  a  device  for increasing the pressure of partially deflated tires, when driving an affected vehicle become unsafe. The device transfers air from a normally inflated tire or gradualy from more tires including the tire of a volunteering vehicle to the deflated tire. When pressurized air is transferred from the inflated tire to the deflated tire,  the pressure  in both tires  equalizes in seconds, with enough pressure in both to continue the journey to the nearest convenient repair point. The device comprises a flexible hose and two adaptors attached to the hose.The first adaptor with no means for pushing a core of a valve, is attached to the valve of the deflated tire and the second adaptor with elements to push the valve core in and for attaching the adaptor to the valve is attached to a normally inflated tire. At this moment pressurized air overcomes resistance of the valve core in the deflated tire thus inflating it. This device can also equalize pressure between any two tires,  pressurize tires of bicycles,  inflatable toys or other products. The air booster is ingeniously simple, very easy to use, inexpensive, safe;  it works  in  seconds,  require minimum storage space and can replace or complement other existing devices. The devices, such as portable compressors, pressurized tanks, foot or hand pumps and pressurized bombs, require substantialy more space, weight more, are more expensive and some require much more inflating time. The pumps also require hard physical work while a throwaway bombs contain noxious gas.
