Patent ZA-846348-B (ZA)
Title: Apparatus for assembly and disassembly of a filter construction
Inventor: COOPER ROYDON BRUCE
IPC: B01D35/30
Filed: 1984-08-15
Abstract: A filter assembly incorporates a system for jacking a fitter canister (13) into and out of engagement with a filter head (11). A threaded jackscrew (15) is mated to a threaded portion of the filter head and rotatably mounted on the filter canister, but longitudinally confined near the canister top. The assembly can accommodate a second class lever (46) the fulcrum of which lies in a notch or other recess (44) in the filter head. The jackscrew includes a plurality of circumferentially-spaced lugs against which a portion of the lever can act. The manual application of force to the free end (46B) of the lever creates a mechanical advantage of the jackscrew lugs (48) such that a torque sufficient to free and turn the jackscrew can be generated. Repeated pivoting of the lever against successive lugs of the jackscrew in a ratchet-like manner unscrews the jackscrew, and the captive canister, from the filter head.

Title: Prosthetic heart valve
Inventor: GABBAY SHLOMO
IPC: A61F2/24
Filed: 1985-05-13
Abstract: An improved prosthetic heart valve comprises a support body or stent covered by a layer of biological tissue having only the smooth surfaces thereof presented outwardly. The stent has a cutaway section and a flexible cusp (11) sewn thereto for opening and closing the valve. The valve cusp is made of pericardial tissue which has been doubled over such that the rough side thereof is folded inwardly. A sewing ring (12) is secured around the base of the stent and is made of pericardial or other biological material, so as to increase the likelihood of the sewing ring becoming covered with epithelium. The smooth-surfaced biological construction of the valve is highly durable and reduces the risk of thrombogenic or infection sites.

Title: Communications systems and methods
Inventor: BAKER DAVID
IPC: H04B1/69
Filed: 2003-07-18
Granted: 2006-03-29
Abstract: A receiver of ultra wideband (UWB) pulse samples incoming signals via an analogue-to-digital (A/D) converter (518) and correlates it (514) with a received reference signal (518) in order to compensate for distortion and multipath reflections (fig. 4b). Digitising the received UWB signal allows the use of digital techniques which decrease the cost, size and power consumption of the receiver. A pattern generator further controls the stored signal in order to provide reference signals for two or more successive pulses with interleaved multipath components, allowing communication over eg. power lines. The received signal can be adjusted in response to the reference signal. The data can be encoded according to both the position and the phase of the pulse.
