Title: Sliding door lock
Inventor: DAUGHERTY EUGENE F
IPC: E05C3/12
Filed: 1987-07-10
Granted: 1992-04-14
Abstract: ABSTRACT OF THE INVENTION    The lock assembly of the present invention is mounted in a lock frame.   A slide member is disposed for translation within the lock frame.   A lock bolt is pivotally mounted within the lock frame and extends through it for engagement with a door keeper in a door frame.  A lock bolt detent is pivotally mounted to the slide member for maintaining the lock bolt in a secure position when the door is closed.  Actuation of movement of the slide member results in movement of the lock bolt detent away from the lock bolt followed by pivotal motion of the lock bolt as a pin on the slide member engages the lock bolt and lifts clear of the door keeper.  The door is sprung open by a spring loaded plunger which extends out of the lock frame.

Abstract: An angiographic catheter includes a relatively soft, tip portion having a preformed curvature, and a resilient body portion extending therefrom having a preformed curvature in the opposite direction. A lumen extends through the catheter for the injection of angiographic dye therethrough to the right coronary artery.  The part of the body portion of the catheter which it in the aortic arch of the patient during use has an amount of curvature which is less than the amount of curvature of the aortic arch, so that the body portion of the catheter is resiliently deformed where it passes through the aortic arch.  The deformation results in the biassing of the tip portion of the catheter into the ostium of the right coronary artery.  Upon insertion into the aorta the preformed catheter is oriented so that the curvature of the body portion of the catheter corresponds in direction to the curvature of the aortic arch. the tip portion of the catheter being disposed above the ostium of the right coronary artery with the distal end of the tip portion touching the wall of the ascending aorta.  The tip portion of the catheter is moved down the wall of the ascending aorta until it reaches the ostium of the right coronary artery.

Title: Circuit board with cooling device
Inventor: SEIBOLD GERHARD
IPC: H05K7/20
Filed: 1989-02-21
Granted: 1993-03-23
Abstract: Abstract Circuit Board with Cooling Device The amount of heat produced during operation of a printed circuit increases with the component density of the cir-cuit. This heat must be removed without causing any damage to the semiconductor components. It is often not sufficient to remove the heat by conduction through the circuit board or by convection. Additional cooling of the circuit board is then necessary. It is known, for example, to attach the circuit board to a hollow copper plate which is traversed by cooling channels. The production of such a copper plate is very complicated and costly. The idea of the invention is to design the circuit board itself as a cooling device. It consists of two outer layers (2) and at least one inner layer (4) which are united by an adhesive or by compression molding using a prepreg. Slots are formed in the inner layer (4) by milling, stamping or cutting. After attach-ment of the outer layers (2), these slots form channels (5) through which a coolant flows.            (Fig. 1)

Abstract: Abstract of the Disclosure Apparatus, and a method for using the apparatus, for stripping solid material containing at least one volatile organic compound (VOC).  The apparatus is provided with a dryer having a heat source to heat the VOC-containing material to a first temperature, hot enough to volatilize the VOC, but below the cracking temperature of the VOC.  The VOC in the dryer is volatilized to form VOC gases.  A means for combusting the VOC gases (e.g. a kiln) heats the VOC gases with excess air to a second temperature, hot enough to destroy the organics in the VOC gases. Simultaneously the combustion means preferably can be used to treat a kiln processable material to form a desired product.  The kiln includes means for feeding the kiln processable material to the heating chamber, means for cooling and recovering the desired product, and means for providing heat for the VOC dryer.  The apparatus also includes a conduit for conducting the gases containing VOC from the dryer to the kiln.

Title: Jam reducing coin entry/way apparatus
Inventor: DOBBINS BOB M
IPC: G07F5/00
Filed: 1989-04-26
Granted: 1993-01-05
Abstract: ABSTRACT      Jam reducing apparatus for use in coin operated machines, such as telephones, acts to prevent the insertion of coins when the entryway is obstructed by foreign matter, assists in dislodging jammed coins and discourages vandals.  The apparatus comprises a coin entryway which includes an inclined surface as part of a flared end of a lid.  An entry slot in an entrance blocker, which is an integral part of the lid, is in substantial alignment with the coin insert slot of the front panel of the machine in normal operation.  The lid is connected to a torsion spring and is associated with a coin reject lever.  The inclined surface of the entryway lies opposite the blocker slot and is angled toward an exit of the coin entryway, which directs a coin into the machine.  In normal use, inserted coins pass through the entryway and are directed into a coin mechanism for coin testing.  Foreign matter inserted into the machine hits the inclined surface and exerts a camming force on the lid, rotating the lid about a torsion spring.          This moves the coin entry slot and the blocker slot out of substantial alignment, preventing the insertion of additional foreign matter or another coin.  Removal of the foreign matter allows the lid to return to its normal operating position under the force of the spring.
