Title: Core locating pin forming and fitting machine; indented pin
Inventor: DODD ALEC GEORGE
IPC: B22C7/02
Filed: 2000-11-02
Abstract: A machine for forming and fitting core support pins into wax 70 surrounding a core 68 prior to covering the wax 70 with a frit includes one or more punch devices 30, (82 Fig 2) within its structure, so as to enable the forming of one or more indentations in each pin, intermediate its ends, thereby providing a designed weakness in the pin to cause it to more reliably follow slight relative movement which occurs between the pins and the part being cast, thus reducing stresses in the surface of the part. The indentation is so positioned as to lie entirely within the frit with one edge coinciding with the interior face thereof. The punch device is contained in a space formed between the end of a rod comprising part of a cylindrical body containing a pressure actuated piston. The rod has two bores. The punch device, when in use, passes through the second bore. A desired length of pin is obtained by loading pin wire into the first bore one then cutting.

Patent GB-2371690-A (GB)
Title: Gain control of a stage of a tuner in a radio frequency receiver based on a quality of the demodulated signal
Inventor: ARAMBEPOLA BERNARD
IPC: H03G3/30
Filed: 2001-01-24
Abstract: A radio frequency receiver for receiving digital signals comprises a tuner (3) for selecting a desired channel for reception. A demodulator (6-16) demodulates the signal in the desired channel and determines at least one quality of the demodulated signal, such as the bit error rate or the mean square error. An automatic gain controller (18) controls the gain of a front-end stage, preferably an attenuator 2, in accordance with the measured quality, for example so as to minimise the error or error rate or so as to reduce the front-end gain and hence tuner power consumption while maintaining an acceptable demodulator performance. Preferably the digital signals are quadrature amplitude modulated (QAM) signals. Further preferable features include the gain control being halted during an acquisition mode and reactivated (e.g. periodically) during a subsequent tracking mode or when a signal quality falls below a predetermined level. Disclosed are details of an algorithm (figure 7) for controlling the said automatic gain controller 18 along with other gain control elements 3,5 of the receiver front-end such that the order in which the different elements are controlled can be governed.
Patent GB-2360346-A (GB)
Title: Monobloc, eg for i.c. engines, having cylinder liners; method of machining and fitting the liners; arrangement of coolant passages
Inventor: WALKER PATRICK MICHAEL CRANSTO
IPC: F02F1/00
Filed: 2001-03-15
Abstract: Each cylinder of the monobloc, eg for an i.c. engine, is provided with a cylinder liner 28. Before insertion, an undercut 38 is machined, eg by boring, at one end of the inside surface 32 of the liner 28 to the finished bore size of the liner. The liner 28 is then fitted into the cylinder 16 with its machined end at the blind end of the cylinder and the remainder of the inside surface 32 of the cylindrical liner is then honed. The invention thus overcomes the problem of honing right up to the blind end of a cylinder. The undercut may have a depth of less than 0.5mm and an axial extent of 4-6mm. The profile of the blind end of the cylinder may be produced by spark erosion. The monobloc may have a bore/stroke ratio of at least 1.25:1. The monobloc may have two cylinders 16, 18 each having its own coolant jacket 80,82 with inlet 88 and exit 90 to provide independent flow of coolant around the cylinders. The monobloc casting may have at least one degree of reflective symmetry and may have a base (74; figs. 1,2) for attachment to a crankcase.

Title: Silencer for the air intake of a machine such as a turbocharger compressor
Inventor: KERR JOHN
IPC: F04D29/66
Filed: 2000-05-05
Abstract: The silencer comprises a housing 1 containing a plurality of axially spaced annular noise attenuating baffles 9-11. Each baffle 9-11 has an outer circumference and an inner circumference defining a central aperture, the central apertures collectively defining an axial outlet flow passage 16 to an outlet aperture 8. The baffles 9-11 define a series of axially spaced generally annular partial flow passages such that air flowing through the silencer is initially split and then merges into the axial outlet passage 16. Each of the annular flow passages curves radially inwards from its outer to its inner circumference in a direction towards the axial outlet 16. Additionally, or alternatively, the dimensions of the annular partial flow passages vary so that the velocity of air flow through the passages is greater for passages closer to the axial outlet aperture 16. A filter membrane 2 may be provided around the housing 1. As an alternative to the cylindrical configuration shown, the silencer/filter may be generally conical for greater strength (fig.3).

Title: Fail-safe tool activating mechanism
Inventor: PATEL DINESH R
IPC: E21B34/10
Filed: 2001-08-21
Abstract: A downhole valve 10 may be opened and closed by alternately pressurising and bleeding a first control line 18 which is in fluid communication with a first surface 14 of an activating member 12 and a second control line 20 which is in fluid communication with a second surface 16 of the activating member 12. The fluid within the control lines 18, 20 is the same as the fluid found in the annulus 7 of the wellbore 5. The development of a leak in the control lines 18, 20 therefore does not by itself result in the actuation or movement of the activating member 12 or valve member (11, fig.1c). The activating member 12 may be an annular piston 24 or a plurality of rod pistons (48, fig. 3a). An indexing mechanism (100, figs. 1b and 2) may also be provided which requires more than one pressure cycle to change the state of the tool.

Inventor: LINCOLN DANIEL J
IPC: H04L7/04
Filed: 2001-10-05
Abstract: A method and apparatus (fig. 5) is provided for passing an N bit wide data stream between two physical devices at high speed. The N bit wide data stream is transmitted in N parallel data streams on N of N+1 differential data lines (78). A predetermined serial sync detect pattern (88) is transferred on the remaining differential data line, referred to as the sync line. A sub interval clock phase is then determined for the sync line that will successfully extract the transmitted sync detect pattern during each half cycle of the clock. All of the N+1 differential data lines (78) are in turn designated as the sync line to determine a sub interval clock phase for each of the respective differential data lines. Data (92) is then extracted from the N data streams by sampling at the sub interval clock phase determined for each particular data line.
