Title: Thermostatic mixing valve
Inventor: SCOTT TONY MARK
IPC: G05D23/13
Filed: 2006-07-18
Abstract: A thermostatic mixing valve 10 includes a valve body 11 having a first fluid inlet 12, a second fluid inlet 13 and a mixed fluid outlet 14, a mixing chamber 16 being located between the respective fluid inlets and the fluid outlet. A thermostatic element 15 is located for exposure to mixed fluid and a piston 17 is arranged for movement within the valve body in response to expansion or contraction of the thermostatic element 15. The piston 17 throttles flow of fluid through the first fluid inlet 12 into the mixing chamber 16 by varying its position relative to a first seat 33, and through the second fluid inlet 13 into the mixing chamber 16 by varying its position relative to a second seat formed as a bore 35 into which the piston 17 can progressively enter. Progression of the piston 17 into the bore 35 initially results in a substantial throttling of the flow of fluid from the second fluid inlet 13 into the mixing chamber 16, while further progression results in engagement between the piston 17 and the second seat 35 to terminate the flow of fluid from the second fluid inlet 13 into the mixing chamber 16.

Title: Method and apparatus for handling dynamically linked function calls with respect to program code conversion
Inventor: BROWN ALEXANDER BARRACLOUGH
IPC: G06F9/455
Filed: 2006-10-02
Abstract: A technique is provided for handling dynamically linked subject function calls arranged pass subject control flow to an intermediate control structure such as a procedure linkage table, then to subject linker code for modifying link information associated with the subject function calls during translation of subject code into target code in a dynamic binary translator. The subject code for execution on a subject processor is received by a translator, and corresponding target code for execution on the target processor is generated. The translator is arranged to build a function linkage table containing an entry giving the location of each function called by the subject code, so that code can be generated by the translator in which subject function calls are associated with code for performing the function, without generating target code corresponding to the intermediate control structure.

Title: Closure valve
Inventor: DOCHERTY PETER MARTIN
IPC: F16K39/02
Filed: 2006-04-06
Abstract: A valve device (10) for closing a drainage duct to avoid spills causing contamination to groundwater comprises a body (12) having an inlet (14) and first and second outlets (16, 18), a shaft (20) located in the body, with first and second plugs (22, 24) located on it, one for each outlet, and a support element (26) inside the body for axially guiding the shaft.

Title: Combining range information with images to produce new images of different perspective
Inventor: HARTMAN RANDOLF G
IPC: G06T15/20
Filed: 2009-11-06
Abstract: Method and system 100 for combining range information with an optical image, comprising: capturing a first optical image of a scene 108 with a camera 102; capturing depth information of the scene with a ranging device 104 (LIDAR, RADAR, SONAR, time of fly camera, or DOPPLER), wherein the field of view of the camera 102 and the range device 104 is substantially the same. Range values are then correlated to at least a portion of the pixels of the first optical image.

Title: Brush holders for electric machines
IPC: H01R39/38
Filed: 1935-04-01
Abstract: 443,810. Brush-holders for dynamoelectric machines. RINGSDORFF-WERKE AKT.-GES., Mehlem, Rhine, Germany, and STOPPANY, A., 11, Via Desciplini, Milan, Italy. April I, 1935, No. 10117. [Class 35] In a brush-holder of the type in which pressure is applied simultaneously to the top and to a side of the brush, one end of a rotatably mounted lever 2 presses upon a casing or hood 8 which through a spring 7 acts resiliently upon the top of the brush 10 while the other end of the lever presses on the side of the brush near the commutator. The upper end of the lever 2 is forked and bears in depressions 8a in the hood on each side of an aperture 8b through which passes a guide rod 6 secured to the brush by clips 5. The clips 5 also serve to limit the travel of the brush which is held when the position 5a is reached. The lower end of the brush is pressed against a spring 3. The brush is guided in slots in the hood 8 and the lower ends of the slots terminate in feet 8c which guide the brush and also prevent the spring 7 from dropping out of the hood during removal of the assembly. Electrical connection is made through the pivot pin 4 which may be in the form of a split tube. The groove 6a in the guide rod reaches the top of the hood 8 when the brush is worn out and the brush is changed by tilting the lever into the position shown in broken lines. The guide pin may be omitted, in which case the upper part 2<11> of the lever is pivoted at 14 to swing sideways as shown in Fig. 7. In order that the tension of the spring 7 may remain substantially uniform throughout the travel of the brush, its unloaded length is approximately nine times the length when a new brush is inserted and about five times greater than when the carbon is entirely worn away.
