  • Barb clamp with smooth bore
    Patent number: 8662542
    Abstract: Disclosed herein are embodiments of a barb clamp for fluid connection to a flexible tube, the flexible tube having an inner bore defined by a predetermined inner diameter for providing a fluid flow path. The barb clamp includes a barb connector having the same predetermined inner diameter as the flexible tube and a tapered end insertable into the tube. A sleeve and collet lock over the tubing and barb connector to prevent liquid material entering between the barb and tube. The tapered end of the barb connector terminates at a point so that there is no transition between the inner diameter of the tube and the inner diameter of the barb connector to provide no pressure differential in the tube between the outside and inside of the barb clamp.

  • Assembly of a shaft and a housing assembly
    Patent number: 8424184
    Abstract: A shaft is held in place within the bore of a housing by a band of resilient material that is located between the shaft and the housing and has a series of projections extending radically inwards. The shaft surface has a first part that lies closer to the longitudinal axis of the bore than a second part, when the shaft and housing are assembled. The shaft is initially inserted into the resilient band, which is held within the bore, such that the first part of the shaft surface is oriented towards one of the projections of the resilient band. In this orientation of the shaft, the projection is not compressed. By orienting the second part of the shaft surface the projection, the projection is brought under compression and the shaft is held firmly within the bore.

  • Light weight electrochromic mirror stack
    Patent number: 8416486
    Abstract: A light weight electrochromic dimmable mirror stack (300, 600) is presented that is composed only of solid-state layers (315, 615) with a total thickness of less than 50 micron and a reflector (310, 610). Normally such a kind of layered device suffers from iridescence due to interference of light waves reflecting at the interfaces between the layers of the electrochromic device. The solution provided by the invention is to pattern at least one of the layers (315, 615) in the device such that the interference effects are smeared out and a more neutral color is obtained. Various possible configurations are described and also the method to produce such a device.
