Abstract: An operator for a rolling door having a curtain barrel shaft rotatable for actuating the door includes a drive gear adapted for connection to one end of the curtain barrel shaft and a second gear (66) adapted for connection to one end of an idler roller. The idler roller in use engages one surface of the door and extends horizontally across the top of the door opening. A third gear (70) is rotatably mounted in the region of the drive gear and the second gear (66) and an electric motor is provided to rotate this third gear (70). In one version of the invention there is a moveable fourth gear (82) in meshing engagement with the third gear (70) and driven thereby. The fourth gear (82) can be swung from a first position where it is in meshing engagement with the second gear (66) to a second position where it is in meshing engagement with the drive gear. A chain loop (46) connectable to the door is driven when the second gear and the idler roller rotate and it is provided to close the door even under pressure. In a second version, a floating clutch drive system employing an endless chain is employed to selectively drive either the shaft about which the door is rolled or the chain loop.

IPC: A01G1/04
Filed: 1986-12-29
Abstract: The invention pertains to culturing ascocarps or fruitbodies of species of the genus Morchella. Mycelia are provided nutrients and subsequently produce sclerotia. Sclerotia store sufficient nutrient to supply the ascocarps that are developed later. The mycelia and attendant sclerotia are established in a nutrient poor substratum. The fungus is induced to give rise to ascocarp development by initially maintaining the fungus in an environment that is poor in exogenous nutrients, and by exposing the fungus to a high level of water. After induction, primordia appear. The period from primordia appearance until midway to maturation of the fruitbodies represents a critical period during which the fruitbodies are prone to abort. During this critical period, particular attention is directed to maintaining favorable conditions. The fruitbodies, which may be grown to maturation, are harvested.

Title: Heating apparatus
Inventor: YAMAGUCHI KIMIAKI
IPC: H05B6/68
Filed: 1990-04-18
Granted: 1994-10-25
Abstract: A heating apparatus such as a microwave oven in which thermal energy of high-temperature vapor generated by heating an object is detected by a pyroelectric element and a resulting detection signal is used to control (stop) a heat source such as a microwave source, etc.  Among AC voltages generated by the pyro-electric element due to heat exchange of the pyroelectric element, a voltage of a polarity generated at the time of heat discharge (temperature decrease) of the pyroelectric element is selectively eliminated through a circuit means.  A voltage generated by heat exchange between air moving slowly in a heating chamber and the pyroelectric element caused by the rotation of a turn-table or the like is eliminated by another circuit means.  A control section controls the operation of the heat source by deciding an output signal of the pyro-electric element by comparing it with a detection level determined in accordance with a noise level for a predetermined length of time after the start of the heating operation.  Erroneous detection is thus prevented which otherwise might be caused by a noise voltage generated in the pyroelectric element by the thermal energy of a hot air staying in the heating chamber after the energization of the heat source or a second heat source.

Title: Method of and apparatus for numbering and routing calls through a communication network
Inventor: FUNK MICHAEL W
IPC: H04Q3/02
Filed: 1991-04-24
Granted: 1996-06-04
Abstract: A communication network uses a network switch number (NSN) and a class-of-service classification (COS) code to route calls through the network. When a call is received at an originating switch of the network, the dialed number is used to select the NSN which identifies a network terminating switch which connects to the called party. The network uses received call signaling information and stored trunk information and possibly network database information to determine the COScode. The COS code is also used at the terminating switch to identify the type of service trunk to connect to the called party. In another feature, only the network switch number is used to route the call over the network. In accordance with yetanother feature, the COS code may be used to select specific network trunks without requiring the specification of the NSN.

Title: Digital signal recording/reproducing apparatus for use with digital signals having different transmission rates
Inventor: KUBOTA YUKIO
IPC: G11B5/53
Filed: 1991-07-02
Granted: 2000-03-21
Abstract: Digital signal recording and reproducing apparatus for recording digital signals in successive tracks of given pitch on a record medium and for reproducing digital signals therefrom. A rotary head assembly including two pairs of head subassemblies angularly separated by approximately 180°, with each subassembly comprised of a pair of heads displaced from each other in a direction parallel to the track pitch, is driven at a predetermined rotation speed to record digital signals selectively supplied at respectively different original transmission rates which exhibit a predetermined ratio. The digital signals are timebase modified to have substantially the same data rate even though their original transmission rates differ from each other; and are coupled to the rotary head assembly. The record medium is driven during a recording mode at respectively different speeds determined by the original transmission rate of the selectively supplied digital signal, whereby the number of tracks recorded on the record medium during a unit time period T (where T is the time for the rotary head assembly to make a predetermined number of rotations) corresponds to the original transmission rate. The record medium is driven during a reproducing mode at the same speed as was used during recording, whereby during the time period T the rotary head assembly reproduces digital signals from twice the number of tracks that had been recorded during that same time period T.      The reproduced digital signals axe recovered substantially without defects at their original transmission rate by way of a memory.

Filed: 1991-08-28
Granted: 2001-06-05
Abstract: A support arrangement for a blade of a construction machine is disclosed where the blade is located to one side of the construction machine. The support arrangement includes two support towers spaced in the length of the frame of the machine with these support towers accommodating variation in the elevation of the blade. The blade is pivotally secured at a forward end thereof to one of the support structures and secured adjacent the other end of the blade to the other support structure by means of two hydraulic cylinders which extend outwardly from the support structure. These hydraulic cylinders also include an arrangement for controlling the angle of the two hydraulic cylinders relative to the connected support structure. The arrangement for controlling the angle of the two hydraulic cylinders accommodates limited, rapid upward movement of the blade. This arrangement allows convenient adjustment of the blade to any desired operating position to one side of the construction machine while also providing an inherently strong support arrangement. This arrangement has particular application for snow wings normally secured to a motor grader or truck.

Abstract: A steering bearing assembly is provided for connecting the front wheel and handle bars of a bicycle to the frame.  The assembly includes a steerer tube, connected to the front wheel and passing through a head tube on the frame.  Bearing assemblies on the upper and lower ends of the head tube allow the steerer tube to pivot within the head tube.  The upper bearing assembly has a first race connected to the head tube and a second race having a tapered contact surface.  Above the second race on the steerer tube is a compression ring having a gap so the ring can be compressed against the steerer tube.  The connector of a stem is located on the steerer tube above the compression ring.  The handle bars of the bicycle are connected to the stem.  An adjuster nut is threaded into the upper end of the steerer tube, exerting a downward force on the connector and the compression ring.  The second race compresses the compression ring, locking the upper bearing assembly in place on the steerer tube.  The connector is then clamped onto the steerer tube.
