Title: System for monitorimg atm cross-connecting apparatus by inside-apparatus monitoring cell
Inventor: NAITO HIDETOSHI
IPC: H04L12/70
Filed: 1992-04-29
Abstract: A system for monitoring an ATM cross-connecting apparatus by inputting a test cell through a path for a main signal into the ATM cross-connecting apparatus, and examining the cell after the cell passed through the ATM cross-connecting apparatus. An initial value of a PN sequence and the PN sequence generated based on the initial bit sequence is written in the test cell before inputting to the ATM cross-connecting apparatus. When examining the test cell, the initial bit sequence and the PN sequence are read from the cell, a PN sequence is generated based on the initial bit sequence, and is then compared with the PN sequence read from the test cell to detect an error in the test cell. In addition, a bit pattern indicating a primitive polynomial to generate the PN sequence may be written in the test cell. In this case, the bit pattern is used for generating the PN sequence when examining the test cell. Further, the same VPI values may be written in both the header and the information field of the test cell before inputting the cell to the ATM cross-connecting apparatus, and the VPI value in the information field is compared with a VPI value in the header of the test cell when examining the test cell.

Title: Apparatus for reburning ash material of a previously burned primary fuel
Inventor: PIEKOS STANLEY J
IPC: F23J3/06
Filed: 1992-11-02
Abstract: Apparatus for reburning ash material of a pre-viously burned primary fuel includes a reburn combustion vessel having an inlet for receiving ash material from a primary combustion unit such as a boiler or furnace and an outlet for discharging the products of combustion from the vessel produced from burning the ash material. The outlet of the ash reburn vessel is connected to the primary combustion unit at an elevated height above the firing level.  The reburned ash material moves in a com-bustion path or loop that is in parallel with at least a portion of the combustion path of the primary fuel in the primary combustion unit.  A floor is provided in the ash reburn vessel for supporting a discrete bubbling bed of burning ash material and the floor includes a plural-ity of spaced apart openings distributed relatively uni-formly over substantially all of the area of the floor. Combustion air is introduced into the reburn vessel at a relatively low velocity to provide a source of underfire combustion air for the bubbling bed.  Combustion air is also introduced at an upper level in the vessel above the bubbling bed to provide an overfire source of com-bustion for the upwardly moving unburned components of ash material carried along with the products of combus-tion rising out of the bubbling bed.  The bubbling bed includes an air injector assembly in each of the floor openings comprising a central conduit that is open at its upper end above the level of the floor and a bubble cap is mounted over the end of the conduit for directing incoming combustion air downwardly towards the adjacent floor to form gas bubbles that tend to float or rise upwardly in the burning bed of ash material of the bub-bling bed.  A control system is provided for sensing the temperature of the products of combustion of the reburn vessel and for sensing the height of the discrete bub-bling bed of burning ash material above the floor so that the flow of combustion air is selectively control-lable in response to the sensory inputs.

Title: Arrangement for registering the instant grinding charge volume of a grinding drum
Inventor: PERSSON STURE
IPC: B02C17/20
Filed: 1992-06-17
Abstract: ABSTRACT            The invention relates to an arrangement for recording the instant volume of grinding charge in the mill drum of a rotary drum mill of the kind provided with an internal lifting device. In order to enable the volume of grinding charge to be used in a better way as a parameter for controlling mill operation, it is pro-posed, among other things, that the lifting device (7) is resilient and is provided with a load detecting device (12) which, during each drum revolution, detects when the lifting device comes into engagement with, and is in engagement with the grinding charge present in the drum (4) and leaves, or is caused to leave, engagement with the grinding charge. The arrangement also includes a tension sensing device (19) which registers the ten-sion on the load detector, this tension being contingent on the load to which the lifting device is subjected by the grinding charge.

Title: Method and apparatus for establishing voice and tone signalling communication in a trunked system
Inventor: BANE RONALD L
IPC: H04W84/08
Filed: 1991-09-03
Abstract: A communication system (100) is provided comprising a communication resource controller (110) wherein the likelihood of success for establishing synchronous digital communication with a communication unit (120) is substantially greater than the likelihood of success for establishing analog communication. The communication unit may establish analog communication after the communication resource controller receives a digital access code from the communication unit. The analog communication is deferred until the received signal strength from the communication resource controller is above a predetermined level which makes the establishment of analog communication substantially likely.

Title: Coatings for laser detector etalons
Inventor: SIEBERT EDWARD T
IPC: G01J3/26
Filed: 1993-03-12
Abstract: PATENT     IMPROVED COATINGS FOR LASER DETECTOR ETALONS                ABSTRACT OF THE DISCLOSURE           This invention provides embodiments of etalons (10, 14, 18, 22) that eliminate or minimize a falloff of relative  radiation modulation  as  a function of wavelength or FOV.  A first embodiment employs dispersive coating,  such as a rugate  (12a,  12b, 16),  to  correct  for the phase  shift across  an etalon step.   A  second  embodiment  employs  a dispersive coating,  such as a rugate  (20a,  20b, 24), that provides a stepless etalon in which the phase shifts are generated by the coating.  It is shown  that  in  a  rugate  the  phase  shift on reflection is directly related to the phase of a sinusoidal index of refraction profile within the rugate, while the frequency of the sinusoidal index of refraction profile determines the wavelength at which the phase shift occurs. By changing the phase of the sinusoidal index of refraction variation as the period of the sinusoidal index of refraction variation is changed,  a phase shift of incident radiation is produced that is a function of the wavelength of the incident radiation.

Title: Self-plugging blind fastener
Inventor: DENHAM KEITH
IPC: F16B19/10
Filed: 1993-07-23
Abstract: ABSTRACT            A self-plugging blind fastener (10, 74, 90) suitable for fastening apertured  sheets  together,  and of  the  type comprising a body (12, 78) having a shank (16), headed at one end, and an axial bore (20) in which is disposed an elongate stem (14, 76, 92) which, in use, is pulled to expand the shank (16) and lock part of the stem (14, 76, 92) in the body (12, 78), has improved means for locking the stem (14, 76, 92) in the body (12, 78).  The head end of the bore (20) is of reduced diameter and presents a stop-shoulder (30).  The stop-shoulder (30) is an annular skirt (34) partly separated from surrounding material by an annular cleavage (32), and presents a planar stop-face (31, 84) facing away from the head-end.   The stem (14, 76, 92) comprises a plug (42) which is connected by a breakneck (46) to a stem-tail (40) for pulling the plug (42) into the bore (20) of the body (12, 78). The plug has an annular locking recess (50) spaced from the breakneck (46), and is radially enlarged on the side of the locking recess (50) remote from the breakneck (46) to provide a plug-shoulder (62) and shank-enlarging means (66, 68, 69).  The plug-shoulder (62) presents a planar face (64, 94) for engaging the stop face (31, 84) of the body (12, 78) and deforming the annular skirt (34) into the locking recess (50) during setting of the fastener (10, 74, 90).  The planar face (64) of the plug (42) and the planar stop-face (31) of the body (12) may both be at right angles to the axis of the bore (20), or either the planar face (94) or the stop-face (84) may be inclined at an angle not greater than 10° to a plane at right angles to the axis, thereby enabling deformation of the skirt (34) to begin at a lower force than would be required if the faces (64 and 84 or 31 and 94) were parallel.
