Abstract: Process for the manufacture, by a sol-gel route and compression with heating, of a composite material consisting of a fibrous reinforcement and of a vitro-ceramic or ceramic matrix based on silica. 
<??>The process of the invention is characterised in that the premature crystallisation of the matrix originating from the sol is delayed by the addition of a crystallisation-retarding agent to the sol. 
<??>This process makes it possible to obtain well-densified composite materials which have a residual porosity of less than 10%, this being done without adding new nucleating agents.

Abstract: A recliner mechanism is disclosed for rotating an automobile vehicle seat with respect to the automobile floor. The recliner mechanism comprises a first plate member that is constrained from rotating relative to the vehicle floor and a second plate member that is selectively lockable with said first plate member. The second plate member is rotatable relative to the vehicle floor when it is unlocked from the first plate member and the seat is attached to the second plate member to rotate with the second plate member. An actuator handle is pivotally connected to the second plate member so as to rotate with the second plate member and the vehicle seat. The actuator member actuates an arrangement of linkages to lock and unlock the second plate member relative to the first plate member. Since the actuator handle is connected to the rotating second plate member, the handle will rotate with the seat and second plate member and thus be easily accessible even at the new seat position. The recliner assembly is sturdily constructed and consists of relatively few moving parts and in addition is axially and vertically compact.

Abstract: CARRIER FRAME FOR A QUICK COUPLER                    ABSTRACT OF THE DISCLOSURE A quick attachment holder for connecting an attachment to the boom arms of a loader includes right-hand and left-hand end portions connected by a semi-rigid cross tube, without additional structural cross members.  A pin connection of the holder end portions to the tube causes the left- and right-hand end portions to generally move together while permitting several degrees of relative rotational movement between end portions to aid in the reconnection of the attachment even when there is slight misalignment between the holder and the attachment.  The cross tube is located on the pivot center of the holder so that only torque loads are applied to the tube. The pin connection will shear if the tube is accidentally over-torqued, and individual components of the holder are replaceable.

Title: Demodulating system capable of accurately equalizing received signals using error correction codes
Inventor: MIZOGUCHI SHOICHI
IPC: H04L27/00
Filed: 1991-03-05
Granted: 1996-04-30
Abstract: In a demodulating system for demodulating a modulated signal into decoded signals (S11'-12', S21'-22'), an error signal correcting circuit (55) is used in correcting discrimination error signals (Ep, Eq) supplied from a demodulator (52) in compliance with error location signals (Spl-2, Sql-2) supplied from an error-correcting decoder (54) and in producing corrected discrimination error signals (Ep', Eq') for supply to an adaptive equalizer (51) which is additionally supplied with polarity signals (Dp, Dq) from a delay circuit (53).  The modulated signal is equalized in accordance with the corrected discrimination error signals and the polarity signals, demodulated into demodulated signals and the discrimination error signals, and error corrected and decoded into the decoded signals.  The delay circuit delays P-channel and Q-channel polarity bits of the demodulated signal into the polarity signals.  The error-correcting decoder produces the error location signals by using P-channel and Q-channel error correcting code bits of the demodulated signals.          The modulated signal may be supplied first to the demodulator and then to the equalizer.

Abstract: A casement window locking system includes a rotatable locking cam mounted in the frame jamb with a window catch access opening on one side and a locking lever access opening on the opposite side.  The locking lever has a U-shaped inner end which embraces the locking cam when the two members are engaged and a tab on the locking cam engages a shoulder on the locking lever to prevent withdrawal of the locking lever until a tool is used to raise the locking cam when the tool is inserted through the catch opening. In an alternative embodiment, a spring clip may be placed on top of the locking cam and it includes a shoulder for engaging the shoulder on the locking lever.  The removable locking lever makes it possible to install and finish the window without the locking lever and change locking levers to color coordinate with the room interior.

Filed: 1991-10-23
Granted: 1995-11-28
Abstract: An in-mold label dispenser for a blow molding machine includes a dispensing head mounted on a base for movement along a first path from adjacent a label magazine to between the open sections of a mold and a label carrier mounted on the dispensing head for movement along a second path substantially transverse to the first path from a retracted to an extended position.  A drive mechanism is mounted in the base for moving the dispensing head along the first path and the label carrier along the second path in co-ordination with the opening of the mold.  The drive mechanism includes an elongated support extending between the base and the mold sections for supporting the dispensing head as it moves along the first path and means for oscillating the elongated support about an axis transverse to the second path.  A lever assembly is connected between the elongated support and the label carrier to provide movement of the label carrier along the second path for receiving a label at the label magazine and depositing it within the mold cavity.  An adjustable stop assembly is provided on the label carrier for stopping movement of the label carrier along the second path after the label carrier has moved a sufficient distance into the mold section to establish a gap of predetermined width between the label and the wall of the mold cavity.  The lever assembly includes a bias means which is so arranged as to permit continued movement of the oscillating support after the stop assembly has been engaged to stop movement of the label carrier, thereby preventing damage to the label carrier.

Abstract: The machining centre serves for grinding workpieces with complex shaped surfaces, such as turbines or jet engine blades.  One or several workpieces are clamped in a workpiece chucking device. The latter is displaceable along an X and a Y axis. Additionally, each workpiece is clamped rotatably around its longitudinal axis.  A support device is disposed on a stand, and is displaceable along a vertical Z axial direction.  One or several automatically exchangeable grinding attachments are inserted in support device.  Each grinding attachment comprises grinding means driveable from support device. The support device is inclinable around an axis of inclination, which runs parallel to the Y axis.  Each grinding attachment is rotatable by any angle around a grinding attachment longitudinal axis, which runs parallel to the Z axis when the support device is in the uninclined state.  All said axes are numerically controlled.  The machining centre is used to achieve surface improvements in the workpieces with simultaneous correction of production errors.  Thanks to the exchangeable grinding attachments placed ready in a tool store, automatic grinding with only very short stoppage times is possible.

Abstract: A 2-input/2-output directional coupler is arranged as an element coupler/splitter for a first stage, and 1-input/2-output coupler/splitters are used as element coupler/splitters for a second stage and its subsequent stages. Output ports of these element coupler/splitters are concatenated with input ports of other element coupler/splitters to form a 2-input/multi-output coupler/splitter.      An optical signal can be inputted through one input port of the first-stage 2-input/2-output directional coupler, and an optical signal for optical line monitoring can be inputted through the other input port. It is unnecessary, therefore, to use an optical wavelength division multiplexer/demultiplexer or other optical part which conventionally is connected at the time of optical line monitoring.
