Title: Omnidirectional drive and steering unit.
Inventor: KISS GEORGE ROBERT
IPC: B62D11/04
Filed: 1993-04-08
Abstract: A vehicle or conveyor is driven by one or more drive units each having a pair of wheels 3 which are driven independently eg by respective electric motors 2 and gearboxes 4. The motors 2 may be mounted on plates 5 via telescopic suspension elements 6. The or each drive unit is thus rotated about a steering axis 7 by the torque resulting from the differential drive forces. A control system monitors the rotation of the drive unit about the steering axis, and other relevant variables, in order to control the motion of the drive unit relative to the driven surface. The analogue or digital motion control signals can specify instantaneous motion parameters or higher-level, macro-motion commands for specific path types. <IMAGE>

The socket may include an annular member 32a and the element may be bonded in the selected orientation or frictionally, but adjustably, held in position. The bottom portion 23 may comprise two separate parts, the connection between the parts passing through the sockets, (Figure 12). Alternatively, sockets may be circumferentially spaced (Figure 12), both portions 23 and 21 being of plastics material. The coupling 22 may include headed pins extending through a rubber isolator bonded to the top portion into a mounting member (52, 47, 49, Figure 17). <IMAGE>

Title: Soldering method
Inventor: OCHIAI MASAYUKI
IPC: H05K3/34
Filed: 1993-03-19
Abstract: A method of soldering in which a solder is applied to a first part to be soldered and any oxide film on the thus formed presoldering is removed by, for example, a flux is characterised in that the solder is then coated with an organic solvent to prevent further oxidation and a second part to be soldered is contacted with the first part. The resulting assembly is heated so that the solder melts and bonds the first and second parts together and so that the organic solvent evaporates. Thus soldering can be carried out without the need to clean any flux away after soldering. The solder may be Au-20Sn; Pb-3.5Ag-1.55n or Pb-55n and the organic solvent may be tetraethylene glycol. The first part may be a semiconductor chip and the second part may be a printed substrate for mounting the semiconductor chip. <IMAGE>

Patent GB-976481-A (GB)
Abstract: 976,481. Controlling burners. W. OERTLI A.G. Jan. 13, 1961 [Jan. 14, I960], No. 1620/61. Heading F4T. [Also in Divisions G1 and H2] An apparatus for controlling an oil burner (not shown) comprises two change-over switches A, B actuated by a common slide 8 actuated by a bi-metal element C heated by an electrical heating coil 6. Each switch comprises a bearing element 9, a switching element 12, stationary contacts 10, 11 and a coil spring 13 extending from the switching element 12 to the slide 8. The latter is mounted on rockable levers 14, 20 extending from the bearing elements. Heating the bi-metal element C causes the slide 8 to move to the right from the neutral position 0 of the levers 14, 20. When position I is reached switch A changes its contacts with snap action and later when position III is reached switch B does likewise. At the return movement of the slide 8 the switch A changes its contacts at position II and the switch B changes its contacts at position IV but position IV cannot be achieved by the cooling of the bi-metal element C but is achieved by the use'of a manual device G comprising a member 27 mounted on a leaf spring 28 and having a sloping face adapted to engage the lever 20. The slide 8 can be pre vented from returning to the neutral position O from position I by the hooked end of an armature H of a relay D energized by a photoconductive resistor or a photo-voltaic cell P exposed to the burner flame. At starting the switches A, B are in the positions shown in Figs. 2, 4, and a lamp E is energized. (The lamp current is insufficient to rotate a motor M for supplying a fuel/air mixture to the burner.) When a thermostat T closes its contacts current is supplied to a transistorized amplifier V for the photoconductive resistor P and to an ignition transformer Z and to the heating coil 6 of the bi-metal element C. After 20 seconds switch A changes its contacts and the burner motor M is energized. If ignition is successful relay D is energized by the photoconductive resistor P and opens contact d to de-energize both the ignition transformer and the heating coil 6. The switches A, B are held in this position by the hooked end of the armature H. If ignition does not occur the contact d remains closed and the coil 6 continues to heat the bi-metal element until switch B changes its contacts to de-energize the amplifier V, the ignition transformer Z and the motor M and to energize lamps F, F<SP>1</SP>. The bi-metal element then cools and the slide 8 therefore returns to the neutral position O. The switch A but not the switch B changes its contacts on this return of the slide. The bi-metal element C consists of a bi-metal strip 3 serving to compensate for fluctuations in ambient temperature and a parallel bimetal strip 5 around which the heating coil 6 is disposed.

IPC: G06F9/46
Filed: 1998-01-07
Abstract: In a client/server computing system for processing a transaction, the client/server computing system being of at least a three-tier process type, where a first tier process 31 initiates the transaction and contacts a second tier process 32 to further the transaction which in turn contacts a third tier process 33 which contains local data to be updated in the transaction, a server, which runs the second tier process, has a means for receiving a transaction context from the first tier process requesting that the second tier process be registered in the transaction and a means for passing on the transaction context to the third tier process informing the third tier process that it should register itself into the transaction directly with the first tier process without going through the second tier process. This greatly reduces the required number of cross process flows.

IPC: F04B33/00
Filed: 1998-06-26
Abstract: A gas or vapour pump, such as a bicycle pump, comprises a pump housing 1 with an internal bore 2 which tapers inwards towards an outlet 3. A radially compressible piston 4, which may be made of a deformable elastomer, synthetic foam or rubber material, is cup-shaped and has an annular inclined side wall 6 which maintains sealing contact with the internal surfaces of the tapered bore 2. A piston rod 7 is supported within the bore 2 by a guide 9, which comprises a series of elements or fingers (10, Fig 3) in contact with the internal surfaces of the bore 2. In use, there is a reduction in the relative force required to move the piston 4 as is moved towards the outlet 3, due to the decreasing cross-sectional area of the bore.
