Title: Nozzle assembly for hot air torch
Inventor: SESTRAP ARVO M
IPC: F23D14/48
Filed: 1988-09-27
Granted: 1992-10-20
Abstract: ABSTRACT OF THE DISCLOSURE           A nozzle assembly for use in a hot air torch wherein the hot air torch utilizes a source of compressed air and a source of gaseous fuel.  The hot air torch has a handle portion which holds a first pipe carrying pressurized air and a second pipe carrying propane under pressure.  The first pipe containing pressurized air splits into two passageways, each passageway having a valve with which flow can be regulated.  As propane travels through the second pipe to an exhaust outlet nozzle, pressurized air travels into a burner tube and an annular plenur surrounding the burner tube.  The burner tube has circumferentially spaced openings.  The compressed air from the plenum goes through the openings and travels radially inwardly toward the exhaust nozzle. The exhaust nozzle has a generally frusto-conical shaped exterior side surface to present a frusto-conical surface against which air jets from the circumferentially spaced openings in the burner tube impinge.  The frusto-conical side surface and the radially inwardly positioned air jets cause the air to converge with and impinge upon the nozzle.  Air in a swirling motion mixes effectively with the gaseous fuel providing rapid combustion at a position upstream from the nozzle.

Title: Method and apparatus for assuring pacer programming is compatible with the lead
Inventor: BAKER ROSS G JR
IPC: A61N1/372
Filed: 1989-04-10
Granted: 1995-04-04
Abstract: A series of test signals are generated by a microprocessor of a pacemaker to determine whether a bipolar or unipolar lead is attached to an implanted cardiac pacemaker restricting programming of said pacemaker to only an unipolar pacing mode unless the presence of an operational bipolar lead is detected.  Detection is accomplished by generating a series of low frequency high impedance pulses, applying them to lead contacts and sensing a return signal. If a return signal is detected, then that indicates either a unipolar lead is connected to the pacemaker or that the ring conductor of a bipolar lead is open and bipolar pacing must be inhibited.

Abstract: ABSTRACT: Pneumatic actuator with permanent magnet control valve latching.     A bistable electronically controlled pneumatically powered transducer for use, for example, as a valve mechanism actuator in an internal combustion engine is disclosed. The transducer has an armature including a piston which is coupled to an engine valve, for example. The piston is powered by a pneumatic source and includes pneumatic damping with a one-way return of air compressed beyond source pressure back to the air source as it nears its destination position. Air supplied to power the piston may be differentially controlled to compensate for asymmetric resistance to movement and the air damping may be differentially controlled to provide dissimilar damping at the two extremes of piston motion. The armature is held in each of its extreme positions by pneumatic pressure under the control of control valves which are in turn held in their closed positions by permanent magnet latching arrangements and are released therefrom to supply air to the piston to be pneumatically driven to the other extreme position by an electromagnetic arrangement which temporarily neutralizes the permanent magnetic field of the latching arrangement.

Abstract: Abstract of the Disclosure A reinforced eyeglass  frame assembly having a frame front and temple members, a pair of hinge members pivotally coupling the temple members to the frame front between open and  closed  positions,  and  a  pair  of  reinforcing  tubes slidably coupled to the temple members.  When the temple members are in their closed positions, the reinforcing tubes are located in their first positions spaced from the hinge members allowing for free pivotal movement of the temple members.  When the temple members are pivoted to their open positions, the reinforcing tubes are moved to their second positions surrounding the hinge members and locking them against pivotal movement. The tubes and hinge members are sized so that the tubes frictionally engage a part of the frame front and the hinge members, when in their second positions, to retain the tubes over the hinge members.  The reinforcing tubes are preferably formed of a polymeric mate-rial, such as polycarbonate, that is stronger and stiffer than the polymeric material  forming the  frame  front and temple members, such as cellulose acetate.

Granted: 1993-08-24
Abstract: ABSTRACT OF THE DISCLOSURE        A method is disclosed for restricting the delivery and receipt  of  electronic  messages  which  are  delivered  to selected recipients via a computer network. Each individual message  or  individual  component  of  a multiple  component electronic message is transmitted in association with an electronic message profile which may include restrictions designated  by  the  transmitter  with  respect  to  the recipient s security classification,  management level,  or address. Preferably the electronic message profile will also include identifying information with regard to the source and type of message associated therewith.  Each electronic message profile is then utilized to automatically control the  delivery  and  receipt  of  its  associated  electronic message by comparison with a recipient profile which was previously established.  In this manner a transmitter may specify that delivery of a selected electronic message or selected  component  of  an  electronic  message  should  be automatically  cancelled  unless the  recipient  meets  a specified  security clearance,  management  level,  or other criteria. Similarly, a recipient may select a profile which precludes  receipt  of  any  electronic  message  from  a particular source or of a particular type.
