Abstract: A tamper-evident closure construction for a container with a neck having a discharge opening therein includes a base cap having a base wall and a nozzle portion projecting from the base wall and an annular flange projecting radially outwardly from the nozzle portion adjacent to the base wall and having a frustoconical first cam surface thereon and a flat planar first stop surface thereon. The construction also includes an overcap with a cylindrical, flexible and resilient skirt connected to the base wall by a circular array of frangible webs, and having a flat planar second stop surface at the distal end thereof and an annular groove mateably receiving the annular flange and defining a frustoconical second cam surface engaging the first cam surface. When the overcap is moved from the initial position along the nozzle portion and away from the base wall the frangible webs are broken, the cam surfaces flexing the overcap skirt until it clears the annular flange, whereupon it returns to an unflexed condition wherein the stop surfaces are engageable with each other to prevent return of the overcap to its initial position.

Title: Key telephone system and interface unit for key telephone
Inventor: NIIYA NORIMASA
IPC: H04M1/71
Filed: 2001-01-12
Granted: 2003-04-08
Abstract: An interface unit connected between a telephone and a telephone network sets a data transmission speed to an optimum speed. The interface unit transmits a type query signal to the telephone terminal at a first speed. The telephone terminal transmits a type signal to the interface unit at the first speed in response to the type query signal. When the interface unit receives the type signal from the telephone terminal, the interface unit changes a transmission speed to a second speed higher than the first speed if the received type signal indicates that the telephone terminal is capable of transmitting data at the second speed. The interface unit also transmits a speed change request to the telephone terminal at the second speed.

The awareness co-presence clients communicate with the co-presence server (22) and define an awareness state of the client. The co-presence server (22) opens a communication channel (52B) or an observation channel (52A) with each client depending on the awareness state of each client per retrieved data object. For observation channels, the co-presence server (22) indicates to each client which other clients have retrieved the same data object.

Title: Controlled phase delay between beams for writing bragg gratings
Inventor: SCEATS MARK
IPC: G02B5/28
Filed: 1999-05-28
Granted: 2009-12-22
Abstract: At least two beams of light form an inter-ference pattern (39) for writing a grating structure on a photosensitive waveguide (38), where the in-terference pattern (39) is controlled by modulat-ing the relative phase of the beams. The modula-tion may be via an electro-optic, magneto-optic, or acousto-optic phase modulator (34), or via a mechanically driven phase modulator (34) com-prising a wedge, waveplate or phase mask. In the latter case the phase mask can also act as a beam-splitter (33) for forming the beams. Extended gratings can be written by moving the waveguide (38) while controlling the relative phase shift, and can comprise chirped, apodized and arbitra-try grating profiles. Noise can be reduced via an optoelectronic feedback loop. In one embodi-ment the relative phase is modulated via an elec-tro-optic modulator (32) acting on a polarized beam, which is then split into two beams by a polarisation beamsplitter (33) such that one beam passes through a half-wave plate (34), to form interference pattern (39).

Abstract: A circuit board (26) is wave soldered as it is carried by a conveyor (30) through a solder wave (16) established in a solder reservoir. Disposed on both sides of the solder wave are gas plenums (240, 250) which discharge shield gas. Each gas plenum includes a top wall (245, 255), a side wall (246, 254), and a bottom wall (243, 253). The side wall is spaced horizontally from the wave, and the bottom wall is submerged within the solder (11). The side and (optionally) top walls include orifices (245, 255) for directing shield gas: (i) at high velocity toward the solder wave to protect the solder wave with an atmosphere of shield gas, and (ii) upwardly toward an underside of the circuit board to strip entrained air therefrom. Instead of being submerged within the solder, the bottom wall could be spaced above the solder and provided with orifices to emit shield gas downwardly between the plenum and solder reservoir to create an inert atmosphere above the solder. A divider (70, 270) disposed within the plenum forms sub-chambers communicating with orifices in respective walls of the plenum so that different gas velocities can be entitled from the orifices. The gas plenums can be rotatably adjustable and further adjustable either vertically or horizontally.

Each attachment member, which normally assumes a louver attachment position, and which is moveable to a louver insertion position, has a leg with base leg part extending from the bar member, an outer leg part extending from and aligned with the base leg part and a head portion transverse to both the outer leg part and the base leg part when the attachment member is in the louver attachment position. The outer leg part is more flexible than and bendable relative to the base leg part which enables the attachment member to be moved to the louver insertion position where the head portion of the attachment member is at least somewhat generally aligned with the base part while remaining at generally transverse of the outer leg part of the attachment member. The plastic material of the attachment member has sufficient memory to cause the outer leg part to realign with the base leg part in moving the attachment member away from the louver insertion position back to the louver attachment position.
