Title: Self-watering air-pruning plant tray system
Inventor: HUANG BARNEY K
IPC: A01G9/10
Filed: 1992-07-08
Granted: 1999-09-21
Abstract: The present invention entails a plant growing tray system which includes a tray with a plurality of individual plant cells having an open top and bottom and a detachable screen or perforated bottom. Each tray cell is designed to contain and hold a plant growing medium such as peat cake or peat-soil mix. A detachable bottom secured to the bottom part of the plant tray provides air-pruning of plant roots to grow superior plants and can be conveniently removed from the plant tray for easy removal of the individual plants or seedlings from the tray bottom. Air-pruning of plant roots eliminates root binding or tangling and accelerates root branching resulting in enhanced root branching and accelerated plant growth in the cell and after transplanting.      The plant tray has a surrounding edge to hold a water level above the tray bottom so that it can uniformly water the plants from top of the tray cells or micro-feeding holes of each cell for self watering and to maintain uniform root zone temperature throughout the tray. The detachable screen or perforated bottom can be press fitted or slide fitted to the tray bottom to hold the peat mix and to provide effective air-pruning of the plant roots.

Filed: 1992-09-22
Granted: 2000-12-05
Abstract: A novel bayonet tube, heat-exchange reactor is provided herein. The reactor includes an outer tube with an inlet end for introducing a process stream therethrough and a closed outlet end. An inner tube, which is open at both ends, is coaxially-arranged within the outer tube and is spaced-apart from the outer tube. A catalyst is disposed within an annular space confined between the outer tube and the inner tube.  The reactor includes a sleeve which externally surrounds the outer tube and defines therebetween a conduit for passage of a heat-transferring medium between the sleeve and the outer tube. The sleeve includes a plurality of perforations extending over a portion of the length thereof from a region close to the outlet end of the outer tube to a region between the outlet end and the inlet end for introducing the heat-transferring medium into the conduit. The components are arranged in such a way that the heat-transferring medium is progressively-supplied to the conduit and flows through the perforated length of the sleeve and along the external surface of the outer tube, in counterflow and indirect heat-exchange with the process stream passing through the catalyst in the annular space between the outer and inner tubes of the reactor. The heat-exchange reactor has a structure which includes one or more of the following: a) the perforations in the sleeve have a diameter of between 1 mm and 3mm, the perforations being arrayed with a pitch of between 10 mm and 100 mm, b) the perforated length of the sleeve constitutes between 5% and 75% of the length of the sleeve extending from the outlet end to the inlet end of the outer tube, and c) the conduit has a width of between 0.01 and 0.08 times that of the internal diameter of the outer tube. By having such structure, the lifetime of the reactor tubes is increased through reduced wall temperatures in critical parts of the tubes.

Title: Scanning arrangement and method
Inventor: SHEPARD HOWARD
IPC: G06K7/10
Filed: 1992-12-01
Granted: 2004-04-13
Abstract: A scanning arrangement located within a scanning device which is operative for repetitively scanning indicia having parts of different light reflectivity, for example, bar code symbols, and more particularly, pertains to a novel scanning motor of the arrangement for enabling a scan element which is supported by a holder structure mounted on a mylar motor to implement angular oscillatory movements in a linear loan direction between a pair of loan end positions.      Hereby, pursuant to the structure of the scanning device, the scanning arrangement is preferably mounted on a single printed circuit board located within a lightweight scanning device of a hand-held housing of gun-shaped configuration which may be readily held and manipulated by a user of the scanning device. The structure of the scanning motor and of the scanning arrangement which are mounted on a printed circuit board is considerably simplified through the construction of the various components being essentially of molded plastic material, and through the utilization of a mylar leaf spring which limits the end scan positions of a scan element or mirror which is oscillated by a read-start device including a permanent magnet mounted on an arm of the holder for the scan mirror.

Patent CA-2114760-C (CA)
Title: Locking ring for an acetabular cup
Inventor: ROHR WILLIAM
IPC: A61F2/34
Filed: 1994-02-02
Granted: 2004-05-04
Abstract: The metal lock ring of the invention has an oblong exterior periphery which allows the ring to have a small "width" and a larger "height." The small "width" provides a strong locking mechanism on the poly liner and the larger "height" allows the ring to remain secure within the groove of the metal shell prior to and during assembly of the polyethylene liner. The ring has a chamfer on its inside leading edges defining its width to facilitate assembly of the liner. This optimizes the ease of assembly and is simpler and more economical to produce than a chamfer all the way around the oblong ring. In the preferred embodiment, the lock ring has a constant thickness such that the inner periphery and the outer periphery are oval.      In an alternative embodiment, the metal lock ring has a round inner diameter and a round outer diameter that are not concentric, thereby creating a thickening of the ring at one end. The shape of the alternative lock ring provides for substantial contact between the lock ring and the poly liner about the liner. The thickened area of the ring retains the ring within the metal cup prior to and during assembly of the poly liner. The thickened portion of the ring may have scallops or notches formed therein to increase the flexibility of the ring.

Patent CA-2139911-C (CA)
Inventor: YAMASHITA KAZUO
IPC: H03F1/30

Granted: 1998-07-07
Abstract: A class AB push-pull drive circuit has two NPN transistors Q1, Q2 and two PNP transistors Q3, Q4, the emitters of which are connected together. A constant voltage circuit maintains voltages between the bases of transistors Q1 and Q3 and between the bases of transistors Q2 and Q4 constant. A differential input voltage is applied across the bases of the transistors Q1 and Q2. The collector currents in the transistors Q1, Q3, Q2 and Q4 increase or decrease in an exponential and differential manner. When the collector currents are in their differential relationship, they are inverted and added to provide a class AB drive current and to increase the output amplitude. The symmetry can also be improved.          Since any difference between signal amplification path lengths is eliminated, a differential phase between paths is less likely to be generated in the high-frequency region. Since there is no feedback or the like for class AB drive, it is difficult for any abnormal oscillation to be produced. Since the constant voltage circuits are formed by diodes, the temperature characteristics of the transistors Q1 to Q4 can be compensated. Furthermore, the class AB push-pull drive circuit can be driven by a relatively low voltage. The bipolar transistors Q1 - Q4 may be replaced by FETs.
