Title: A rotatable joint
Inventor: WIRTH NICHOLAS JOHN PETER
IPC: F16H1/28
Filed: 2000-08-18
Abstract: A rotatable joint between external members comprises a stator incorporating a stator gear 1 and a rotor incorporating a rotor gear 2, these gears being engaged by pinion gears 3 and 4 which are coupled in a unitary structure. The arrangement is such that rotation of gear 3 around the gear 1 leads to a small movement of the gear 2 about axis O and so provides a gear arrangement of high reduction ratio. The stator and rotor are each provided with a connector structure 30, 31, to which external members 33, 34 may be connected. The gear 3 may be driven by a sun gear which, in turn, is driven by an electric motor. A potentiometer may measure the rotation between the external members which may be the arms of a robot.

Title: Reprogramming a microprocessor through a serial port
Inventor: OLIVER JAMES A
IPC: G06F9/445
Filed: 1997-09-19
Abstract: An administrative computer (14, fig. 1) is connected to a serial port 18 on a machine (12, fig. 1) containing a microprocessor 30 or some other memory device to be reprogrammed. A first sequence of signals is sent from the administrative computer to the microprocessor, via control grabber hardware circuit 28, to change the microprocessor from a normal mode to a bootstrap mode. A new program is then loaded from the administrative computer, and a second signal sequence is sent to reset the microprocessor. Both digital (fig. 4) and analogue (fig. 5) implementations of the control grabber circuit 28, which constantly monitors the state of handshake and receive data lines and identifies the proper sequence of signals, are described. In an alternative embodiment, a preinstalled program transfers functional control of the microprocessor to the serial port when the sequence of signals is received, and the new program is loaded into the microprocessor RAM.

Title: Welding construction
Inventor: NOISHIKI KOJI
IPC: F28F21/08
Filed: 2001-06-26
Abstract: A welding construction comprises two members 1,3 welded to each other by a welding part 5, wherein at least one of the members 1,3 together with the welding part 5 are formed from an aluminium alloy containing magnesium. A backing metal 4 is provided behind the welding part 5 and seal-welding material 6,7 is used to seal-weld the two members 1,3 to the backing metal 4, the magnesium content of the backing metal 4 and the seal-welding material 6,7 not being more than the magnesium content of the welding part 5. Preferably, the magnesium content of the backing metal and the seal-welding material is not more than 2.0 weight %, while the magnesium content of the welding part 5 and the two members 1,3 is not less than 2.0 weight %. The members 1,3 are preferably an apparatus body and a header respectively in a heat exchanger, but could also comprise two pipes (31,32; figure 4) whose ends are welded together. The heat exchanger or welded pipe construction is preferably used for cooling/transporting natural gas containing mercury. The backing metal 4 and seal-welding material 6,7 have a low magnesium content, which prevents the formation of a   b   layer (Mg<SB>2</SB>Al<SB>3</SB>) in, or around the periphery of, the welding part 5, therefore preventing stress corrosion cracking of the welding construction on exposure to the mercury in the natural gas.

Title: Waste material storage and volume reduction by crushing/shredding
Inventor: CHAPMAN PAULINE LESLEY
IPC: B65F1/10
Filed: 2002-10-14
Abstract: A waste material storage apparatus, such as a bottle bank 1, comprises a walled housing 3a-d with waste material receiving inlets (6a-c), an angled tray/conduit 8, a hopper 9 which connects the inlets to a crushing/shredding means 10 and a control means/sensor (such as a weight balance or a light sensor) which activate/deactivates the crusher/shredder when the amount of waste in conduit/tray or hopper reaches a pre-determined level (weight or height).
