Abstract: OXIDATION-INHIBITED CARBON-CARBON COMPOSITES     ABSTRACT OF THE DISCLOSURE        Carbon-carbon composites consisting of graphite fibers reinforcing a carbon matrix are protected from oxidation by a B2O3 glass coating which includes a refractory oxide to stabilize the viscosity of the glass. Precursors of B2O3 and the refractory oxide are dispersed into a resin, the resin is used to impregnate fibrous graphite or fibrous graphitizable material, the sheets are laid up as plies and the laid-up plies are carbonized and graphitized using heat and pressure to form a carbon-carbon composite structure. The composite structure is then coated with an additional mix of resin and precursors, and the coated structure is heated to carbonize the resin and leave a seal coat on the structure.   Then an outer shell of a refractory material is deposited on the structure.  Oxygen which seeps into the structure at high temperatures is initially scavenged by the RO and B2O3 precursors, converting the same to a B2O3-RO glass which protects both the internal pore surfaces of the composite as well as the outer structural surfaces from oxidation.

Title: Aircraft cabin noise control apparatus
Inventor: ELLIOTT STEPHEN J
IPC: B64C1/40
Filed: 1987-06-22
Granted: 1994-03-22
Abstract: ABSTRACT            Aircraft Cabin Noise Control Apparatus In propeller or fan driven aircraft, cabin noise levels may be reduced by adjustment of the phase relationship between a reference propeller or fan and some or all of the other propellers or fans.     An aircraft cabin (1) contains four microphones (2, 3, 4, 5) and two loudspeakers (6, 7) which form the active elements of a noise control system.  The microphone outputs are fed via amplifiers (12, 13, 14, 15) to a digital signal processor (11) having an adaptation algorithm in a memory store.  The processor generates an error signal which is used to adjust the synchrophase angle between the reference propeller (10) and a synchrophased propeller (9), controlled by a synchrophaser (8).  Thus the synchrophase angle is varied dynamically during flight to minimise propeller noise in the cabin over a range of flying conditions.

Title: Apparatus for recording and reading an optical disc, having reduced offset in its tracking error signal
Inventor: ARAI SHIGERU
IPC: G11B7/085
Filed: 1987-12-02
Granted: 1992-01-07
Abstract: ABSTRACT         Push-pull type tracking error signal produced by the reflected light from pits in ID area of an optical disc is aver-aged and sampled over a period while the spot scans the ID pits, and is held for each sector, thus named as a first sampled track-ing error signal.  The tracking error signal is also sampled while the light is scanning over a vacant zone having no pit in a data area, thus named as a second sampled tracking error signal.  This vacant zone to be sampled is located either before or after a sequence of data bits in each sector.  The first sampled tracking error signal is smaller than the second sampled tracking error signal, because of the AC component therein produced by the pits.          Thus, when an offset of the tracking exists, though the tracking error signal is almost zero by the servo control the first sampled tracking error signal is not zero.  Therefore, difference of two tracking error signals indicates amount of the offset.  This offset signal may be visually monitored for adjusting the offset of the apparatus, or may be fed back for the tracking servo.  The invention can be applied to a disc format having no mirror mark.          The circuit of the invention can be simple and inexpensive, because no high frequency need be output therefrom.

Title: Article transport apparatus
Inventor: HARTNESS THOMAS S
IPC: B65B21/06
Filed: 1988-01-22
Granted: 1991-12-24
Abstract: ABSTRACT In a case packing machine, an article transport apparatus for transporting groups of containers from a continuously-running infeed conveyor of the case packing machine to a case loading station.  The article transport apparatus includes a reciprocating carriage having longitudinally extending bladders which are inflatable for gripping a group of containers to the carriage.  The reciprocating carriage moves upstream to encompass a group of containers, and upon inflation of the bladders, the bladders grip the group of containers to the carriage.  The carriage then moves downstream, and upon deflation of the bladders, deposits the group of containers at the loading station.  As the reciprocating carriage moves away from the infeed conveyor towards the loading station, a space free of containers, or gap, is created temporarily on the infeed conveyor, through which a pivoting stop bar arrangement pivots upwardly from below the infeed conveyor to a position above the infeed conveyor for restraining the containers on the infeed conveyor.  The pivoting stop bar arrangement restrains the containers on the infeed conveyor until the reciprocating carriage returns to grip another group of containers. Individual lane containers are provided between conveyor lane dividers which allow the conveyor lane dividers to be supported from lower portions thereof.
