Abstract: FRAME CONSTRUCTION OF A PRESS   SECTION IN A PAPER MACHINE                    ABSTRACT OF THE DISCLOSURE        Press section of a paper machine provided with a frame construction which comprises first a front frame and then a rear frame in a direction of running of a paper web through the machine.          Press rolls are mounted on the front and rear frames.  Between the front frame and the rear frame, and above the press roll combination, there is an at least partially open space through which at least most of the press rolls can be replaced.  The space also facilitates replacement of the upper press fabrics.  The press roll which forms the second nip is the press section is attached to a first intermediate frame part separate from the rear and intermediate frames and arranged to be pivotable by means of power units around horizontal articulation shafts in conjunction with the front frame.          This press roll is connected to the first intermediate frame part through a second intermediate frame part by means of horizontal joints.  The second intermediate frame part can be pivoted around the horizontal articulated joints by means of power units.  Between the first intermediate frame part and the front frame, there are openable and lockable intermediate parts by means of which the first intermediate frame part can be rigidly fixed to the front frame.  The intermediate parts can be opened so that the first intermediate frame part can be pivoted towards the front frame, at least when the suction roll in the press section is being replaced.

Abstract: NUCLEAR FUEL PARTICLES AND METHOD OF MAKING      NUCLEAR FUEL COMPACTS THEREFROM               ABSTRACT OF THE DISCLOSURE Methods for making nuclear fuel compacts exhibiting low heavy metal contamination and fewer defective coatings following compact fabrication from a mixture of hardenable binder, such as petroleum pitch, and nuclear fuel particles having multiple layer fission-product-retentive coatings, with the dense outermost layer of the fission-product-retentive coating being surrounded by a protective overcoating, e.g., pyrocarbon having a density between about 1 and 1.3 g/cm3.  Such particles can be pre-compacted in molds under relatively high pressures and then combined with a fluid binder which is ultimately carbonized to produce carbonaceous nuclear fuel compacts having relatively high fuel loadings.

Abstract: BUILT-IN VACUUM CLEANING SYSTEM WITH IMPROVED ACOUSTIC DAMPING DESIGN            ABSTRACT     An improved design for the central power and suction unit of built-in vacuum cleaning systems, which improved design provides significant-acoustic clamping to substantially reduce the noise level generated from the central power and suction unit. The design further permits the canister of the central power and suction unit to rest on the floor. The motors of the central power unit are enclosed within an interior chamber which  includes  at  its  lower end  a baffle  supporting an acoustic damper such as acoustic foam and the interior chamber is vented through exhaust ports. The tips of the armatures are separated from the remainder of the armatures and motors by the baffle and the tips of the armatures extend into another chamber which further includes a second acoustic damper within the chamber and further includes openings for permitting cooling air to enter the chamber. Through this design, the noise level generated from the motors is very substantially reduced while  the  motors  are sufficiently cooled.

Abstract: A circulating fluidized bed reactor comprises a separator including a vortex chamber adjacent the top of the reactor for separating solid material from the flue gases of the reactor. A channel directs flue gases discharged from the reactor and adjacent the top of the reactor in a downward direction. A main portion of the solid material is separated from the gases by a change of flow direction after which the solid material is returned to the lower part of the reactor. The main portion of the gases is directed, after the change of direction, to the vortex chamber where further separation of solid material is effected and the separated solid material is returned to the reactor.

Granted: 2001-08-07
Abstract: A helicopter engine speed reference (66) is increased (113, 103-105) in response to heavy rotor larding (108). The reference speed is faded up (113, 104) at a rather rapid rate to 107% of rated speed (114). After a fixed time interval (118), reduced rotor loading (119) will cause the reference speed to be faded down slowly (120, 103-105) to rated speed (121). If torque exceeds 111% of rated torque (117), the reference speed is similarly faded down. (120, 103-105).

Title: Dough-stretching roller apparatus
Inventor: HAYASHI TORAHIKO
IPC: A21C3/04
Filed: 1991-01-23
Granted: 1995-02-07
Abstract: A dough-stretching roller apparatus is provided to produce a continuous web of dough in a process to manufacture confectionery and bread.  The apparatus includes a pair of upper rollers, a sensor means that detects the width of dough at the gap between the upper rollers, and a controller that controls a motor driving the upper rollers in response to a signal from the sensor means.  The controller decreases the rotational speed of the upper rollers when the sensors detect that the width of dough is broader than a predetermined width of dough passing through the upper rollers, while the controller increases the rotational speed of the upper rollers when the sensors detect that the width of dough is narrower than the predetermined width of the dough passing through the upper rollers.  Thus, even if the amount of dough supplied from a hopper is unstable, production of a stretched web of dough having a constant volume per unit length can be stably continued.
