Latest Patents

Ebrahim Parekh holds two significant patents:

1. **Threaded Split-Bushing Fastener Assembly**: This assembly is crafted for high temperature applications. It consists of a pin with a standard countersunk head at one end and a tapered end at the other, accompanied by a tubular threaded split-bushing, a nut, and a washer. The installation process involves inserting the pin through the parts to be fastened, followed by attaching the washer and split-bushing on the tapered end, and finally securing the nut onto the split-bushing. By tightening the nut, preloading of the fastener assembly is achieved, ensuring a secure and reliable fastening solution.

2. **Tapered Split-Bushing Fastener**: Similar to the above, this fastener is also designed for high temperature applications. The structure includes a pin with a standard countersunk head and a tapered end, along with a split tapered bushing, a washer, and a sleeve featuring an internal taper. Installation requires inserting the pin in the parts to be fastened, adding the washer and split bushing on the tapered end, and pushing the sleeve onto the split bushing. The sleeve's action compresses the split-bushing against the washer, generating axial preload. To lock the fastener in place, a high-temperature adhesive is then injected.
