Title: Method and an apparatus for the production of pipes
Inventor: JAERVENKYLAE JYRI
IPC: B29C48/90
Filed: 1986-09-11
Granted: 1992-03-24
Abstract: Abstract of the Disclosure This invention relates to a method and an apparatus for the production of pipes. In the extrusion of plastic pipes, a circular mould cavity is formed of chill moulds (1, 2) which are semicircular in cross-section and the junction faces of which are pressed against each other. In order to keep the chill moulds tightly against each other, it is known to provide the edge area of the chill moulds (1, 2) with counter pieces (4) which have locking surfaces (5) whereon a press force is exerted by means of a rail of a U-shaped cross-section. In this known solu-tion, great friction forces are created between the locking surface (53 and the rail, and the diameter of the mould increases in a direction perpendicular to the junction faces. These disadvantages are avoided in the present invention wherein the apparatus comprises locking means (6) which follow the movement of the chill moulds (1, 2) and grip the locking surfaces (5) of the chill moulds.            (Figure 4)

Abstract: A FABRICATION PROCESS FOR ALIGNED AND STACKED CMOS DEVICES            Abstract of the Disclosure A process for fabricating aligned, stacked CMOS devices.  Following the formation of the lower FET device, conformal undoped and doped oxide layers are formed thereover so that the level of the upper surface of the common gate electrode is above the doped oxide as formed in the source and drain regions of the lower FET device.  A planarizing photoresist is then deposited and etched in conjunction with the oxide to the upper surface of the gate electrode.  The exposed gate electrode is covered with a gate oxide layer, and a polycrystalline silicon layer for recrystallization to an upper FET device.  Updiffusion from the residuals of doped oxide then creates an upper FET device with source and drain regions aligned to the gate oxide thereof and the underlying common gate electrode.

Title: Modular composite prosthetic foot and leg
Inventor: PHILLIPS VAN L
IPC: A61F2/66
Filed: 1988-03-10
Granted: 1992-05-05
Abstract: ABSTRACT A lower leg prosthesis comprises an elongated pylon formed from resin-impregnated, high-strength filament.  The pylon has an upper extremity, an intermediate shin portion and a lower forward foot portion formed integrally with one another.  The foot portion extends downwardly and forwardly of the shin portion so as to have substantially low energy absorption compliance in response to vertical loads thereupon.  A heel portion is secured to the forward foot portion and is fabricated from the resin-impregnated, high-strength filament.  The shin portion of the pylon has a cross-section with a high moment of inertia about an axis generally aligned with the fore and aft direction and a relatively low area moment of inertia about a horizontal axis perpendicular to the fore and aft direction, whereby the shin portion and the forward foot portion may flex in a vertical fore and aft plane and not in a vertical transverse plane.  The upper extremity of the pylon is rigid to restrict the length of the shin portion and provide for modular fitment of the pylon by being cut and adjusted to an amputee without affecting the compliant response of the shin and foot portions of the pylon.

Abstract: Abstract of the Disclosure The present cutter head assembly includes guide lever members engageable with the trunk of the tree so that the curved cutting and limb stripping blades are maintained parallel with the longitudinal axis of the tree as the tree is pulled through the cutter head assembly by the grapple of a knuckle boom loader or the like.  The cutter head assembly includes a rectangular support frame with a pair of curved cutting and limb stripping blades pivotally supported for movement toward and away from each other and adjacent one end of the rectangular support frame.  The stripping blades define a tree encircling cutting opening therebetween for longitudinal movement of the tree in one direction through the cutting opening.  A pair of curved guide levers is pivotally supported for movement toward and away from each other and adjacent the other end of the rectangular support frame.  The rectangular support frame is supported for a limited amount of pivotal move-ment in both vertical and horizontal planes so that the support frame and the curved stripping blades and guide levers are automatically maintained in alignment with the tree trunk so that the axial alignment of the cutter head is not dependent upon the skill of the operator of the knuckle boom loader.

Granted: 1991-11-12
Abstract: ABSTRACT OF THE DISCLOSURE    A parallel arithmetic-logic unit (PALU) controlled by a microinstruction sequencer and capable of executing conditional operations in a single pass is disclosed.  The PALU generally comprises first and second registers for storing data, a comparator means for continually comparing the values in the registers, and an arithmetic-logic core connected to the registers for performing arithmetic, logical and data move operations on the data in the registers.  The comparator is preferably an unsigned magnitude comparator which outputs flags indicative of the relative status of the values in the registers.          The flags are read by a microinstruction sequencer which then uses the flag information to determine what operation the arithmetic-logic core is to conduct.  Preferably, a shifter is also provided between one of the registers and the arithmetic-logic core.

Abstract: ABSTRACT OF THE DISCLOSURE A platen roll core has a plurality of roll elements, and a spacer interposed between adjacent roll elements for attenuation of propagated vibrations.  The core, if seen in terms of vibrating system, is equivalent to the sum of vibrating systems independent of one another and corresponding to the respective roll elements.  The axial length of each roll element is set to such a value that the natural frequency thereof in an axial flexural oscillation mode is greater than a frequency of vibration applied from a vibration source, thereby to avoid the resonance of the core in the axial flexural oscillation mode with the vibration source, which is a main cause of an increase in noise level.
