Title: Digital audio signal format hub circuit
Inventor: HATFIELD ROBERT JAMES
IPC: G11B20/00
Filed: 2009-07-24
Abstract: An integrated circuit or method, for transferring audio signals between audio transducers and circuits that supply or receive digital audio signals, comprises at least two sets of interface connectors 40a, 40b, 40c for connecting to digital audio links for communicating digital audio signals with external circuits. At least one digital audio interface circuit 43, 45 is provided for converting the audio signals between the format used by the data link and a format used within the integrated circuit. A routing system 74 is connected between the interface connectors 40a, 40b, 40c and the digital audio interface circuit or circuits 43, 45. The routing system 74 is operable to route signals passing through a first set of interface connectors 40b so as to pass through one digital audio interface circuit 45 or another digital audio interface circuit 43 prior to being issued on a further set of connectors or alternatively it may bypass the digital audio interface circuits 43, 45 to directly link a first set of connectors 40b with another set of connectors 40c. Each set of connectors 40a, 40b, 40c may likewise be subject to a plurality of different route arrangements. The integrated circuit or method may provide a digital signal format hub for use in a portable, battery powered telecommunications device.

Title: Adjustable bicycle simulation apparatus
Inventor: MIYAMARU YUKIO
IPC: A63B22/06
Filed: 2009-09-11
Abstract: A bicycle simulation apparatus 10 has a simulation bicycle 12 including a saddle or seat 24, a steering member or handle bars 28 and a front control unit 14 disposed forwardly of the saddle 24. The steering member is separate from the frame of the simulation bicycle, and is connected to the control unit. The control unit has a monitor 82 for displaying moving scenery depending upon the operation of the simulation bicycle. The monitor and steering member can be jointly moved up and down with the upwards movement also proceeding forwards (arrow B). The saddle may also be adjustable up and down with the upwards movement also proceeding backwards (arrow A). This makes it possible for the apparatus to be sized for users of differing heights.

Title: Chain tensioner with a sensor that detects excessive chain elongation
Inventor: LOSANO FIORELLO
IPC: F16H7/08
Filed: 2009-11-09
Abstract: A hydraulic chain tensioner 14, for a valve train chain 11 of an internal combustion engine in a vehicle, comprises a piston 15 that presses a blade on the chain 11 so as to maintain the chain 11 in tension. A sensor 16 detects an axial position of the piston 15 proportional to chain elongation and transmits an alert signal if the chain elongation is excessive. The alert signal from the sensor 16 is transmitted to an electronic control unit (ECU) 20 of the vehicle. Sensor 16 detects micro-displacements in order to evaluate a velocity of the piston 16 and thereby a vibrational state of the chain 11. A method for monitoring the chain elongation is also disclosed, the method includes a phase in which the alert signal is sent if chain elongation is above a predetermined threshold and a corrective action impacting on an ignition fuel strategy is performed. The method uses a computer program product comprising control apparatus in which a computer program having computer-code is stored.

Title: Preventing writeback race in multiple core processors
Inventor: VISHIN SANJAY
IPC: G06F12/08
Filed: 2008-06-20
Abstract: A processor prevents writeback race condition errors by maintaining responsibility for data until the writeback request is confirmed by an intervention message from a cache coherency manager. If a request for the same data arrives before the intervention message, the processor core unit provides the requested data and cancels the pending writeback request. The cache coherency data associated with cache lines indicates whether a request for data has been received prior to the intervention message associated with the writeback request. The cache coherency data of a cache line has a value of modified when the writeback request is initiated. When the intervention message associated with the writeback request is received, the cache lines s cache coherency data is examined. A change in the cache coherency data from the value of modified indicates that the request for data has been received prior to the intervention and the writeback request should be cancelled.

Title: Improvements in or relating to spray-guns for paints and other liquids
IPC: B05B7/04
Filed: 1945-04-24
Abstract: 604,678. Spray-producers. REINHOLD, C. April 24, 1945, Nos. 10276, 10277 and 10278. Convention dates, April 24, 1944, April 24, 1944, and Jan. 6, 1945. [Class 69 (iii)] A trigger-operated portable spray-gun comprises a two-part casing 1, 2 which forms a frame for an atomiser 13, 20 and an electric blower 3, 4 and an air-tight removable cover for the liquid container 9. The part 2 also is extended to form a handle 6. Air enters an aperture 36 in the handle 6, in which impurities are trapped by a felt 39, and passes over the motor 3 through the blower 4 to be forced through semicircular passages 24, 29. The air in passage 24 is ejected through an aperture in a diaphragm 27, into the atomiser tube 20 while the air in the passage 29 builds up pressure in the receptacle, thus aiding the flow of the liquid 11 up the pipe 31. To give a horizontal or vertical flat jet, the atomiser tube 20 has a revolvable cap 21 with diametricallyopposite channels 32, 33 which communicate through vents 34, 35 with the air in the tube 20. The trigger 17 actuates a lever 19 which moves a rod 14 to open the tube 13 normally closed by the head 15 of the rod. A washer 10 hermetically seals the gun and the receptacle which may contain heaters. Fig. 5 shows a modification, of the nozzle in which a cap 72 having webs 76 supporting a nozzle 77 is closed at one end by a liquid-tube 84 and a triggeroperated valve 80. The tube 84 has a flexible extension 85 for liquid and can move to provide a gap at 86 for air to clear out any drops remaining in the nozzle when the trigger is released. The cap and nozzle are removable for cleaning. Alternatively, Fig. 3 (not shown), the cap is held by a bayonet-catch and flexibly retains the nozzle supported by webs on an insert in the mouth of the air-tube. The nozzle may produce a flat spray.

[Class 110 (i)] The suction of a centrifugal pump comprises a U-shaped box with interconnected pivoted vanes for imparting pre-whirl to the fluid. The vanes 8-11 are moved in one direction and the vane 12 is the opposite direction by a hand lever 28 and linkages 24-18 and 25-27. The hand lever 28 is held in any desired position by a bolt 30. In a modification, the pivots of the vanes are off-set from the planes of the vanes. In a further modification which permits the vanes 8-11 to reverse the direction of the pre-whirl, the lever arms 24, 25 are replaced by gearing.

Abstract: 315,729. British Celanese, Ltd., and Dreyfus, H. April 10, 1928. Addition to 165,519. Apparatus for making filaments. - In the method for the downward dry spinning of artificial filaments or threads described in the parent Specification, the filaments or threads are given an extended travel in the spinning cell, that is, they travel a distance of more than three yards therein, but preferably not more than six yards. By reason of the extended travel threads of greater regularity are obtained, while more complete recovery of the solvent is ensured. The extended travel mav be obtained by increasing the height of the cell, or by leading the threads downwardly to a guide or roller in the lower part of the cell around which they pass before ascending to the outlet orifice, or by providing the cell with a lateral or horizontal extension through which the threads pass. The guide or roller within the cell may be used as a stretching device, the threads being if necessary lapped round the roller so as to ensure that the peripheral speed of the roller is imparted to the threads. The cells may be provided with the devices or arrangements described in Specifications 198,023, 203,092, and 300,998.
