Title: Portable radio telephone
Inventor: MARTENSSON NILS ERIK
IPC: H04M1/724
Filed: 1991-03-04
Granted: 2000-05-30
Abstract: A portable radio telephone has a keypad including a plurality of externally accessible keys.  The keys can be disabled (i.e. the keypad can be locked) to prevent accidental actuation thereof by performing a predetermined order of keystrokes using two of the keys which ordinarily have an alternative function associated therewith.  Thus, for example, depression of the # key followed by the ON/OFF key temporarily enables the keyboard lock.  The lock can be disabled simply by repeating the same keystrokes.

Title: Methods and apparatus for providing dynamic invocation of applications in a distributed heterogeneous environment
Inventor: TRAVIS ROBERT L JR
IPC: G06F9/48
Filed: 1991-08-13
Granted: 1996-08-13
Abstract: A method and apparatus providing for the interaction of processes in an object-oriented manner by which a system manages "classes" of data instances and applications rather than managing the data itself.  The names of classes may be stored in a data base which also contains other information about the classes, such as certain common attributes of applications or instances which are supported by the classes.  Applications can remotely invoke other applications by sending messages with parameters.  Using the message names, as well as information about the classes of certain parameters and certain preference information, a reference to a specific method is selected from the data base.  That method will perform the operation specified in the message.  Other information in the data base is then used to locate and execute the actual code to implement the referenced method.

Title: Flareless compression fitting
Inventor: DEWITT PAUL R
IPC: F16L19/12
Filed: 1991-09-13
Granted: 1995-01-17
Abstract: ABSTRACT OF THE DISCLOSURE      A tube connector for sealing a flareless tube to a fitting having a flat sealing face perpendicular to the fitting axis.  The tube connector incorporates a ferrule engaged by a sleeve mounted on the end of the tube and having a flat radial surface for engaging the fitting sealing face.  The ferrule is deformable and establishes a primary wedge type metal-to-metal sealing engagement with the tube by a compression nut threaded upon the fitting.          The  ferrule  radially  bows  under  axial  and radial compression and this deformation suppresses vibration while the shape of the ferrule end engaged by the nut increases the radial forces on the ferrule as the nut is tightened to provide firm tube support remote from the seal region.          The sleeve is provided with an internal undercut adapted to outwardly flare the end of the tube to lock the tube to the sleeve, and radially support the tuba end as the tube is compressed during connection.

Abstract: Disclosed is a galvanized steel sheet which has a tensile strength of not less than 80 kgf/mm2 and a yield ratio of not more than 60%, and which is applicable to members of an automobile body, particularly those requiring strength.  By appropriately controlling the amounts of C within the range of 0.08-0.20 wt%, Mn within the range of 1.5-3.5 wt%, Al within the range of 0.01-0.1 wt%, P 0.01 wt% or less, S 0.01 wt% or less, and one or both of Ti and Nb within the range of 0.01-0.1 wt%, the structure of the steel sheet is formed into a dual-phase structure having a second phase structure.  The steel sheet is recrystallization-annealed, galvanized while it is maintained at a temperature range near 500°C, and then is cooled.  By controlling the rate of cooling the steel sheet, the second phase structure generated is prevented from hardening more than necessary.          The galvanized high-strength steel sheet has a low yield ratio and excellent stretch-flanging properties.

Abstract: A single continuous dough sheet (12) is conveyed by a conveyor (20) up an incline to a dough tension and drive system (38). In the system (38), the dough sheet (12) passes around a lower drive roller (40), around an intermediate drive roller (42), and around an upper drive roller (44). The dough sheet (12) extends at a downward angle to an idler roller (80) which directs the dough sheet (12) generally vertically downward in a flat condition. A  whishbone pushing element (82) having a rounded V-shape forms the first face of the dough sheet (12) into a generally V-shape having two wings. The wings of the V-shape are then guided by an aligning element (96) such as laterally spaced rollers (98, 100) which roll on the opposite face of the wings to form a folded, two-ply continuous dough sheet (14). The angular relationship of the legs (84, 86) of the pushing element (82), the lateral spacing of the rollers (98, 100) of the aligning element (96) and the three dimensional positioning of the pushing element (82) and the aligning element (96) can be adjusted to insure that the free edges in the folded continuous dough sheet (14) are aligned relative to each other.
