Filed: 1990-07-31
Granted: 1994-11-01
Abstract: A palletized container is provided which includes a collapsible receptacle section supported and subtended by the upper surface of a pallet section.  The receptacle section is adjustable relative to the pallet section between set up and collapsed modes.  The receptacle section includes pairs of foldably interconnected outer wall panels.  When the receptacle section is in a set up mode, the pairs of wall panels assume upright opposed relation.  Each panel of a first pair of wall panels includes a pair of foldably connected panel segments which are adapted to assume a planar relation when the receptacle section is in the set up mode.  When the receptacle section is in a collapsed mode, the panel segments of each panel of the first pair assume a folded face-to-face relation and are sandwiched between a second pair of outer wall panels whereby both pairs of outer wall panels overlie the pallet section upper surface.  Each panel of the second pair has a flap connected by a foldline to the bottom edge thereof.  One of the flaps is affixed to the pallet section upper surface.  The edge of each flap opposite the foldline interfit with one another and restrain lateral relative movement therebetween, thereby maintaining the receptacle section in the set up mode.

Title: Wood patch
Inventor: MURPHY DAVID L
IPC: B27C5/00
Filed: 1990-09-21
Granted: 1994-04-05
Abstract: Abstract of the Disclosure An improved wood patch, in combination with a slot formed in a blemished wooden surface, and apparatus and method of manufacture thereof. The improved wood patch has, where the wooden surface to be repaired is horizontal, three faces:  a flat horizontal exterior face, a flat vertical interior face, and an angled arcuate interior face. The patch has both a larger vertical radius of curvature and a larger angle between the flat vertical interior face and the angled arcuate interior face than the slot. Apparatus for manufacture includes a router utilizing a double router bit having a straight cutting edge oriented perpendicular to the axis of rotation of the bit and an angled cutting edge oriented at an angle to the straight cutting edge.        Both relative longitudinal and transverse movement between the wood stock and the double router bit are created by the router being installed on a pneumatically actuated pivoting platform attached to a carriage which is engaged to a longitudinal track, with the router having a cam follower which engages a cam having a series of lobes formed in the shape of the curved intersection of the flat interior face and the arcuate interior face of the wood patch. A series of curved scallop-like protrusions are created on the wood stock which protrusions are subsequently removed by a separate cutting blade, mounted on the carriage behind the double router bit. Utilizing the proper cam, an elongated patch may be formed for a longitudinal series of blemishes on a wooden surface.

Title: Control valve for a hydraulic elevator
Inventor: PELTO-HUIKKO RAIMO
IPC: B66B1/26
Filed: 1990-12-17
Granted: 1995-04-04
Abstract: Control valve for a hydraulic elevator provided with a speed regulating plug which moves in response to the flow of the hydraulic fluid and whose position determines the flow of hydraulic fluid into the actuating cylinder of the elevator.  At each end of the speed regulating plug, there is connected a system of hydraulic channels in which the hydraulic fluid flows, and which communicates with the main hydraulic circuit.  An additional channel is connected to the hydraulic channel system, the additional channel being provided with a flow resistance component comprising a capillary throttle and a pressure compensated reservoir, such  that  the  flow  of  hydraulic  fluid  through  the additional channel is varied in inverse relation to the viscosity of the fluid.  By this means, the closing speed of the speed regulating plug, and thus the deceleration rate of the elevator, is maintained constant throughout the operating temperature range of the hydraulic fluid.

Inventor: IPPONMATSU MASAMICHI
IPC: G01F1/704
Filed: 1992-02-26
Granted: 1999-03-16
Abstract: The disclosed method of measuring the flow of a fluid with a porous particulate ceramic tracer and an optical instrument is characterized in that spherical particles having diameters in the range of 0.5 to 150 µm are used as the tracer.  Inasmuch as the tracer particles for flow measurement are spherical, the sectional area of scattered light to be detected by an optical sensor means is constant regardless of the orientation of particles.  Furthermore, spherical particles have no surface irregularities that might cause concatenation so that individual particles are not agglomerated in tracking a fluid flow, thus contributing to improved measurement accuracy.

Abstract: The present invention is to provide a circuit for detecting humidity in which occurrence of the temperature drift can be inhibited by a simple means and therefore which is able to detect humidity precisely without regard to the temperature of the atmosphere. In a humidity detection circuit including a bridge circuit containing temperature elements, the bridge circuit is connected with a series of a third resistance R3, a current controlling element and a power supply in this order, while a series of fourth and fifth resistances R4 and R5 is arranged in parallel with the series of the R3 and the bridge circuit. In addition a junction between R4 and R5 and another junction between R3 and the bridge circuit are connected separately to a voltage comparing circuit, the output of which is inputted into the current controlling element. In this arrangement, a control section is provided to detect the potential of the junction between the bridge circuit and the third resistance R3. The humidity detection circuit, based upon the detected potential, changes the resistance value of resistance R5 to an optimum level at which the temperature drift does not occur.

Filed: 1993-03-03
Granted: 2002-04-23
Abstract: Disclosed is a karaoke-type entertainment system that allows a participant to sing along with a prerecorded song. The system includes a microphone for producing an input vocal signal that corresponds to the singer's voice, and a pitch corrector samples the input vocal signal and determines its pitch. The pitch corrector shifts the pitch of the input signal to correspond to the pitch of a reference note which in turn corresponds to the correct pitch at which the melody is to be sung. The pitch corrector thereby alters the pitch of the input vocal signal to correspond to the pitch of the reference note so that the participant is singing "on pitch" with the melody.
