Title: Passive joint movement device and method for using the same
Inventor: MORYKWAS MICHAEL J
IPC: A63B21/02
Filed: 1997-09-25
Abstract: A passive movement deivce for exercising a patient's joint is provided. The device includes a resilient foam section and a casing enclosing the foam section within a sealed chamber. The patient's joint is held in position relative to the sealed chamber by a suitable retainer. A vacuum pump is operatively connected with the sealed chamber to selectively provide application and non-application of a reduced pressure, i.e. below atmospheric, to the sealed chamber. The application of the reduced pressure causes the foam section to collapse thereby exerting a force on the joint which causes the joint to move or bend from a predetermined position. The non-application of the reduced pressure to the sealed chamber causes the foam section to expand thereby exerting a force on the joint which causes the joint to move or bend toward the predetermined position.

Title: System for fabrication of indirect dental restoratives
Inventor: ROETZER PATRICK LYNN
IPC: A61C5/77
Filed: 1998-02-13
Abstract: A process for the fabrication of indirect dental restoratives includes the making of a first, pre-operative impression of a tooth to be restored using a first polyvinyl silicone (PVS) material disposed in a clear tray, followed by the preparation of the tooth. A second, final post-operative impression of the tooth is taken utilizing a second PVS material. A tooth model is then made by pouring a low viscosity and suitably rigid, third PVS material into the final impression. Prior to the complete setting of the low viscosity PVS material, a higher viscosity, fourth PVS material is applied onto the model PVS material to form a completed model with base. The model is then fitted into the preoperative impression matrix made from the first PVS material. Layers of composite are packed onto the impression in the clear matrix. The model (with attached base) is then inserted into the composite disposed in the first PVS material and the resulting matrix is placed in a single apparatus for conducting both light and heat cure of the dental composite. The apparatus employs a thermister disposed in a composite material, the thermister/composite assembly being disposed in the curing chamber and connected to a control device which controls a heat lamp also disposed in the apparatus. Curing of the dental composite is performed by heating until the thermister reaches a selected temperature.

IPC: H03H7/06
Filed: 1999-07-29
Abstract: A base band signal is frequency limited by a band limiting circuit 1. The waveform of this output signal rises and falls smoothly against a time axis. A driving circuit 2 functions as a buffer amplifier with voltage gain of 1 between the band limiting circuit 1 and ASK modulation circuit 3, and the output voltage wave is equal to the output waveform of the band limiting circuit 1. The ASK modulation circuit 3 turns on/off a field effect transistor 61 by the output signal voltage from the driving circuit 2, thereby discontinuing the carrier of the microwave band to be externally entered and performing ASK modulation (binary ASK), and provides a desired ASK modulated waveform as a result.

Abstract: A halogenated butyl polymer having improved properties, the butyl polymer derived from a monomer mixture comprising a C4 to C8 monoolefin monomer, a C4 to C14 multiolefin monomer and a styrenic monomer with a catalyst system to produce the butyl polymer. The improved properties include faster cure, higher maximum torque, higher delta torque, relatively stable modulus over time, improved hot air aging properties and improved aged flexure properties. These improved properties are believed to result from direct interaction between the styrenic moieties in the polymer backbone with a crosslinking agent added to vulcanize the halogenated butyl rubber.

Title: Hypersensitive response elicitor fragments and uses thereof
Inventor: LABY RONALD J
IPC: H04N5/44
Filed: 1998-05-28
Abstract: The present invention is directed to isolated fragments of an Erwinia hypersensitive response elicitor protein or polypeptide which fragments elicit a hypersensitive response in plants. Also disclosed are isolated DNA molecules which encode the Erwinia hypersensitive response eliciting fragment. Isolated fragments of hypersensitive response elicitor proteins or polypeptides, which elicit a hypersensitive response, and the isolated DNA molecules that encode them can be used to impart disease resistance to plants, to enhance plant growth, and/or to control insects on plants. This can be achieved by applying the hypersensitive response eliciting fragments in a non-infectious form to plants or plant seeds under conditions effective to impart disease resistance, to enhance plant growth, and/or to control insects on plants or plants grown from the plant seeds. Alternatively, transgenic plants or plant seeds transformed with a DNA molecule encoding a hypersensitive response eliciting fragment can be provided and the transgenic plants or plants resulting from the transgenic plant seeds are grown under conditions effective to impart disease resistance, to enhance plant growth, and/or to control insects on plants or plants grown from the plant seeds.

Title: Packing protector
Inventor: BELIVEAU JEAN-LOUIS
IPC: B65D81/05
Filed: 1999-12-03
Abstract: The packing protector is formed from an elongated strip of flexible cushioning material having an L-shaped cross section defining a vertical wall and a vertical wall. Transversal folding lines are provided in the strip to fold it in the shape of the packing protector. The folding line is formed by a groove spanning transversally on an inner side surface of the vertical wall.      The groove is associated with a V-shaped folding cutout in the horizontal wall shaped to form two matching surfaces which are brought adjacent to each other when the strip is folded, thereby forming a unified wall. One of the two matching surfaces includes a male coupling interlockable with a female coupling in the other matching surface to keep the strip once folded in the form of the packing protector. A packing protector according to the present invention has the advantage of being easy and simple to ship to the user or purchaser in great amounts, as the unfolded strips can be easily piled up for the delivery. And once it is ready to be used, the strip has the advantage of being very easy and simple to be folded into the shape of the packing protector.
