Title: Lamp unit with improved push-in type bulb holder
Inventor: AHRONI JOSEPH M
IPC: F21V19/00
Filed: 1998-09-16
Abstract: A light set has multiple light units mounted on a multi-wire insulated cord, each light unit comprising a plastic push-in lampholders containing a bulb with two lead wires, a socket member receiving a pair of push-in contact elements and lampholder, and a base unit which snaps together with the socket member over the cord preparatory to insertion of the contact elements and lampholders. The contact elements pierce the cord insulation on opposite sides of a cutout through a selected one of the cord wires and establish positive contact with both parts of the severed wire by straddling respective of the wire parts with a pair of sharp prongs. Positive positioning of the bulb leads with respect to the contact elements is established by flexible leg extensions on the lampholders which interfit at their free ends with the leads and swing back to a position in the socket member pressing the leads against the contact elements.

Abstract: An air flow rate measuring apparatus includes a casing having opposite open ends, a flow rectifier mounted within the casing at an upstream-side portion thereof with respect to a direction of flow of fluid to be measured, and at least one fluid pressure detector which is mounted within the casing, and is disposed downstream of the flow rectifier, the fluid pressure detector including at least one differential pressure detector member.  The differential pressure detector member includes a pair of tubular members of an identical configuration, and each of the tubular members has a flattened shape having opposed narrow side walls and opposed wide side walls, and at least one pressure-measuring port is formed through one of the opposed narrow side walls.  The differential pressure detector member further includes a pair of plug members mounted on and closing opposite open ends of each of the tubular members, respectively, one of the pair of plug members having a pressure outlet port.  The at least one pressure-measuring port in one of the pair of tubular members is directed toward an upstream side with respect to a direction of flow of fluid to be measured, thereby forming a total pressure-measuring port, while the at least one pressure-measuring port in the other tubular member is directed toward a downstream side, thereby forming a static pressure-measuring port.

Abstract: An anchor for a mine roof bolt incorporates a single large rib at the top of a segmented shell. This single large rib is forced into the wall of the bore hole by the downward movement of an associated threaded camming nut during the first few revolutions of the roof bolt. The remainder of the outer surface is generally smooth or unserrated and provides a large bearing surface which is urged against the bore hole wall upon further rotation of the bolt. The camming nut has a specific shape flaring substantially near its upper end such that a relative large area of the bore hole wall below the rib is forced into compression.

Inventor: YOUNG JAMES V
IPC: A61H23/02
Filed: 1998-11-13
Abstract: A hand held massage unit used for therapeutic purposes such as to loosen and mobilize bronchial secretions in patients, to improve blood circulation, and to relax muscles. The massage unit includes a vibration-free motor unit having a rotating output shaft directly connected to a vibratory headassembly. The rotational motion of the output shaft is transformed into oscillating orbital motion about the shaft centerline in the adapter portion of the vibratory head assembly by means of an offset cam integrally formed as part of a counterbalanced eccentric. Counterweights within the eccentric reduce the vibrations transmitted to the user's hand and isolate the oscillating vibration of the vibratory head assembly. Undesired rotation of the vibratory head assembly is prevented by a mounting construction between the oscillating adapter components and a stationary portion of the vibratory head assembly secured to the motor unit.

Title: Method and device for microinjection of macromolecules into non-adherent cells
Inventor: DAVIS BRIAN
IPC: A61K48/00
Filed: 1997-12-19
Abstract: The present invention is directed to a method of incorporating foreign material into cells that exist in a non-adherent state. In some embodiments, the method employs a microinjection needle together with an adhesive molecule or apparatus capable of immobilizing cells that exist in a non-adherent state onto a substrate or other surface capable of supporting cell attachment to permit introduction of a desired material, such as nucleic acid, into the cell. The non-adherent cells can be genetically altered by the microinjection of nucleic acid sequences (DNA) of sufficient size to permit direct introduction of said nucleic acid into the chromosomal DNA of the cell, without the use of a retrovirus, adenovirus, or other carrier molecule. The invention also thus provides a method of gene therapy insofar as cells modified according to the defined method, particularly undifferentiated cells such as stem cells, may be created to include a gene or fragment thereof sufficient to replace a deficiency or correct an abnormality or deficiency in the cell, and used in a patient by injection of the cells. The corrected nucleic acid then gives rise to genetically corrected differentiated cell species, and hence an approach useful in treating a number of physiological disorders.

Abstract: The rocker arm cover on a diesel engine can be formed of a rigid molded plastic material to minimize the transmission of noise into the atmosphere. Sonic vibration of the cover can be reduced by reducing the cover material stiffness. The reduced stiffness of the cover material allows the roof area of the cover to be momentarily displaced away from the cylinder head in the presence of an acoustic wave, so that the roof area is not able to develop the restoring force that is necessary for vibrational motion.

Title: Methods and apparatus for handling maintenance messages in extended superframe t1 telephone circuits
Inventor: BARTHOLOMAY WILLIAM G
IPC: H04L12/56
Filed: 1999-09-27
Abstract: An apparatus for handling back-to-back maintenance messages in extended superframe t1 telephone circuits includes a FIFO, a byte counter, and a message length register. According to a method of the invention, when messages are placed in the FIFO, the byte counter counts the message length and places the message length in the message length register. A host controller is required to read the message length register in the time interval following complete receipt of a first message before complete receipt of a second message, but is only required to read the contents of the FIFO before it overflows. According to a presently preferred embodiment of the apparatus, a second register is provided for indicating the current depth of the FIFO. The second register sends an interrupt to the host controller when the contents of the FIFO exceed a threshold.
