At a predetermined point in time Tc after the start of a pulse group, at least one of the interpulse interval TA, pulse width  tau  and pulse repetition period CA of the pulses in the group is/are charged. The predetermined point in time Tc corresponds to an estimated moment at which a molten droplet separator from a wire electrode. Alternatively, the welding apparatus may have a pulse waveform shaping circuit responsive to a droplet separation signal from a droplet separation detector (93), (Fig. 41), so that the envelope of each pulse group has a slope of a first inclination before droplet separation and of a second inclination after droplet separation (Fig. 44). <IMAGE>

Title: Ultra long electromagnetic wave therapeutic device
Inventor: CHENG CHI-CHAO
IPC: A61N2/04
Filed: 1994-07-21
Abstract: An ultra longwave therapeutic device consisting of an insulating outer case 1 with an internal plastic lower base 2, mounted upon which are two magnetic poles 3 made of silicon steel sections and coils 5 of enamel coated copper wire wound around the magnetic poles 3. A silicon steel bar 4 joins the underside of the two poles. A current is passed through the coils 5 and magnetic flux is produced through poles 3. When connected to the A.C. mains, an ultra long electromagnetic wave is generated with a wave length in excess of a million metres which is capable of penetrating any insulation material. Therefore, when a patient lies upon the outer case 1, electromagnetic waves are introduced into the body, creating a therapeutic effect. A pulsating steel bar 6, which lies on top of the poles 3, acts in a reciprocating motion when alternating current is applied to the coils 5 and thus vibrations are transmitted to the patient. The apparatus may improve circulation, adjust internal secretion mechanisms and relieve tendon and muscular stiffness. <IMAGE>

Patent GB-2287621-A (GB)
Title: High performance symmetric arbitration protocol with support for I/O requirements
Inventor: SARANGDHAR NITIN V
IPC: H04L12/403
Filed: 1995-01-17
Abstract: A system and method for providing a high performance symmetric arbitration protocol that includes support for priority agents. The bus arbitration protocol supports two classes of bus agents: symmetric agents and priority agents. The symmetric agents support fair, distributed arbitration using a round-robin algorithm. Each symmetric agent has a unique Agent ID assigned at reset. The algorithm arranges the symmetric agents in a circular order of priority. Each symmetric agent also maintains a bus ownership state of busy or idle and a Rotating ID that reflects the symmetric agent with the lowest priority in the next arbitration event. On an arbitration event, the symmetric agent with the highest priority becomes the symmetric owner. However, the symmetric owner is not necessarily the overall bus owner (i.e., a priority agent may be the overall bus owner). The symmetric owner is allowed to take ownership of the bus and issue a transaction on the bus provided no other action of higher priority is preventing the use of the bus. A symmetric owner can maintain ownership without re-arbitrating if the transaction is either a bus-locked or a burst access transaction. The priority agent(s) has higher priority than the symmetric owner. Once the priority agent arbitrates for the bus, it prevents the symmetric owner from issuing any new transactions on the bus unless the new transaction is part of an ongoing bus-locked operation. <IMAGE>

Title: Elastomeric vibration-damping bushing with hydraulic damping
Inventor: SCIORTINO GIACOMO
IPC: F16F13/14
Filed: 1995-02-18
Abstract: The bushing (10) comprises an inner sleeve (12); an outer sleeve substantially coaxial with the inner sleeve; a block (16) of resilient material retained between the inner sleeve and the outer sleeve, and shaped to define two working chambers (18,20) that are filled with hydraulic fluid. Each working chamber is defined in part by a pair of walls (19,21) of predetermined thickness (T 1 ,T 2 ) which extend between the inner sleeve and the outer sleeve and which curve outwardly from the inner sleeve to the outer sleeve. A channel (22) interconnects the two chambers for fluid flow therebetween. The thickness of the walls of one working chamber is different from the thickness of the walls of the other working chamber in order to improve the control of compliance characteristics for the bushing.

Patent GB-2296942-A (GB)
Title: Fluid circulation centrifugal cleaner
Inventor: PENNY STEVEN CHARLES
IPC: B04B5/00
Filed: 1995-12-12
Abstract: A centrifugal fluid cleaning arrangement 100 in a fluid circulation system includes a centrifugal cleaner 100' having passages 106,107 through which only a proportion of the circulated fluid is diverted and drainage assistance means 102 which consists of a venturi arrangement 111 through which non-diverted fluid is passed. The non-diverted flow passes through the venturi, developing locally a significant pressure drop in a region which is open to an induction port 108 connected to a clean fluid holding sump 101' whereby cleaned fluid is entrained into the non-diverted fluid and returned to the circulation. Whilst the pressure difference between inlet and induction ports is sufficient to drive the centrifugal cleaner rotor, the absolute pressures of the supply to, and drain from, the cleaner do not depend on the ambient atmospheric pressure. Also the overall pressure drop of the venturi arrangement is small permitting it to be included within a closed circulation system. A regulator may control the flow through the venturi arrangement by directing a proportion of the flow through a by-pass. The drainage assistance means may be separate from the centrifugal cleaner.

Title: Voltage converter dual capacitor ignition circuit for an airbag
Inventor: KINOSHITA KENICHI
IPC: B60R21/01
Filed: 1994-03-10
Abstract: An ignition circuit for ensuring the ignition of a squib for an airbag in a vehicle which uses a voltage converter and controls the timing of the discharge of a pair of capacitors. A first capacitor 12 and a second capacitor 13 are charged in parallel by a voltage converter 30 connected to the battery 11. In the event of a crash, sensor switch 17 is closed and the control circuit 10 makes the second transistor 31 active just after a collision is detected and the first transistor 19 becomes active a predetermined time after the collision has been detected thereby ensuring sufficient current flows for long enough through the squib 16 to allow ignition. In a second embodiment, the more the battery voltage falls the more the period between the discharge of the first and second capacitor is decreased so as to ensure ignition by controlling the timing of the discharge of the second capacitor.

Title: Cryopump with electronically controlled regeneration
Inventor: BARTLETT ALLEN J
IPC: F04B37/08
Filed: 1994-02-23
Abstract: In a partial regeneration process, the second stage of a cryopump is heated as purge gas is applied. In a test loop 104, the purge gas is turned off and the roughing valve is opened 108. If the cryopump is judged to be sufficiently empty of gases 110 from the second stage by being roughed to a sufficiently low pressure in a short period of time the system proceeds to a reconditioning phase. If the system fails the test, however, it is repurged with a burst of warm purge gas 112 and then retested. After passing the emptiness test, the pressure is further reduced by the roughing pump as heat is applied to the second stage 114. The heat is then turned off for cool down as the system continues to be rough pumped 118 to a base pressure, at which the roughing valve is cycled to maintain the cryopump pressure near to the base pressure. Where multiple cryopumps are coupled to a common roughing pump, they are processed through a partial regeneration sequence in lock step to avoid cross contamination.

Title: Drive mechanism
Inventor: COBB ANTHONY RICHARD
IPC: A61M5/145
Filed: 1996-02-02
Abstract: A lead screw drive comprises a lead screw (10) which is rotated by a motor. A traveller (40) is clamped at one end to a rod (14) parallel to the lead screw, the rod in turn engaging the plunger of a medical syringe. The other end of the traveller (40) has a U-shaped engaging element (42) with the two parallel arms (44, 46) thereof having grooves on their inner surfaces for engaging with the lead screw thread. The grooves also extend upwardly and downwardly of the region of engagement with the lead screw thread and radial movement of the engaging element (42) therefore moves the region of contact with the lead screw without causing disengagement. The device is particularly suitable for use with a medical syringe pump, to prevent inadvertent disengagement of the engaging element from the lead screw.
