Title: Lathe or the like having screw with oppositely threaded sections
Inventor: CHEN HSI-KUAN
IPC: B23B21/00
Filed: 2001-10-03
Abstract: A lathe comprises a frame 1', a work table 2' and a tool holder assembly 3'. The work table and tool holder assembly may be traversed towards and away from one another by means of a fixed rotatable screw rod 12' mounted along the length of the frame having two oppositely or counter threaded sections 121' and 122' and nuts 23' and 312' on the work table and tool holder assembly. The frame may include two parallel lengthwise rails 11' for guiding the work table and tool holder assembly through sliders 22' and 311'. The frame may be aligned vertically or horizontally (see fig 4). The screw rod may be reversibly driven by a servo motor M. The invention increases the speed of traversing the work table and tool holder assembly and, when used with a vertical screw rod, avoids the need for balance weights or the like to place a substantially constant load on the servo motor M and prevents the work table or tool holder assembly moving downwards when the servo motor M is not energised.

Title: De-activation of combustion chambers in a multi-combustion chamber i.c. engine
Inventor: TURNER JAMES WILLIAM GRIFFITH
IPC: F01N13/04
Filed: 2002-06-21
Abstract: A first throttle valve 17 controls flow of air to first combustion chambers 11,14 while a second throttle valve 18 controls flow of air to second combustion chambers 12,13. Fuel injectors 19,22 deliver fuel to the first combustion chambers 11,14 while second fuel injectors 20,2 1 deliver fuel to the second combustion chambers 12,13. Exhaust gas from the first combustion chambers 11,14 and the second combustion chambers 12,13 is passed through first and second catalytic converters 26,29, respectively. At high engine operating loads, fuel and air is supplied to all combustion chambers and both throttle valves 17,18 are effective. At low engine operating loads, the method comprises deactivating in turn the first combustion chambers 11,14 and then the second combustion chambers 12,13 in a cyclical fashion so that at any time during such operation some combustion chambers (11,14 or 12,13) are active while the other combustion chambers are deactivated by ceasing supply of fuel and opening wide the relevant throttle 17,18. The invention keeps the catalytic converters at their operating temperatures and is particularly applicable to V8 and V12 engines.

Title: Range hood above a cooking stove
Inventor: YEUNG PETER
IPC: F24C15/20
Filed: 2003-07-07
Abstract: A range hood (20) with a motor housing (22) having top and bottom surfaces and angled walls so as to facilitate the travel of entrained air drawn in through the air inlets by the operation of the fans. The top surface is larger than the bottom surface and angling of the walls is greatest towards the rear of the housing. A ventilation hole is located in the rear of the top surface. Because the ventilation hole is set more rearwardly in relation to the air inlets, the inlets may be positioned further forward in the range hood body as compared to the motor housings of the prior art thereby increasing the suction area over a cooking surface. The motor housing (22) may include an integral grease catcher catcher in the form of an upstanding wall (50, Fig 3).

Title: Method and apparatus for crack detection in railway lines
Inventor: YATES JOHN ROBERT
IPC: G01N21/89
Filed: 2004-03-25
Abstract: A system (100) and method for detecting flaws or cracks in rails (1) of a railway line/track, from a vehicle (3) moving along the railway line/track, comprises means (2,6,7) to transiently thermally load the rail of the track at a point along its length. The loading may be direct heating or by physical loading stressing the rail and temporarily raising its temperature.

Processing means (20) provide a map of the surface temperature of the rail along a line of the loaded points as the vehicle moves over the track. A second detector 5 enables the same point to be viewed again later and the change in surface temperature to be analysed and any characteristic or flaws or cracks in the rail to be identified.

Patent GB-2398427-A (GB)
Title: Contactors
Inventor: CONNELL RICHARD ANTHONY
IPC: H01F7/16
Filed: 2002-11-27
Abstract: A two-pole contactor includes a contact assembly (24) for making and breaking contact between a pair of fixed contacts (8, 10) at each pole. The contact assembly is a plastics moulding carrying a resiliently supported shorting bar and is coupled to a plunger of a solenoid. In order to make a contact, the plunger accelerates the contact assembly towards the fixed contacts, until the contact bar touches the fixed contacts. The plunger and the remainder of the contact assembly then continues to move through a predetermined distance, loading the resiliently supported shorting bar against the fixed contacts. To break contact, the procedure is reversed. The solenoid has two plungers slidable within a common bore and separated by a compression spring. Permanent magnets situated at each end of the solenoid core induce an attractive force between the plungers. When the separation between the plungers is smaller than a threshold separation, the magnetic attraction overcomes the spring force and the plungers latch together. When the separation between the plungers is greater than the threshold separation, the force exerted by the spring is greater than the magnetic attraction and so the plungers de-latch in a separated position, in which the contacts at both poles of the contactor are open.
