Title: Digital phase locked loop
Inventor: KILLIAN MAVERICK MARTIN
IPC: H03L7/08
Filed: 1995-05-15
Abstract: A digital oscillator (11) is synchronized to a master clock by comparing the master clock to an output of the digital oscillator (11) by providing both to a first register (15) which enables a counter (16). The counter (16) increments while enabled until cleared. The output of the counter (16) is then compared with a stored signal. Depending upon the match with the stored signal, the output of the digital oscillator (11) is either slowed, advanced or maintained. The output from the digital oscillator (11) is then fed back to an input of the digital phase locked loop (10). <IMAGE>
Patent GB-2312496-A (GB)
Title: Pressure vessel assembly
Inventor: CHAN SEK KWAN
IPC: B60R21/268
Filed: 1996-04-26
Abstract: The invention provides a pressure vessel assembly 10 having a thermally weakenable closure element 12. A seal-breaking pyrotechnic charge 20, comprising portions of pyrotechnic sheet material 29 overlying each other and spaced apart to provide passage for flame and combustion products of the burning sheet, is located sufficiently close to the closure element 12 for the flame and combustion products to impinge thereon. The closure element 12 is thereby heated to a temperature at which it becomes sufficiently weak to burst under the pressure of gas stored in the pressure vessel 10. Rupture of the closure element 12 is rapid and reliable and the assembly is therefore advantageous for use in an inflator for an 'air-bag' in a vehicle occupant restraint safety system. The preferred pyrotechnic charge is a coiled charge of pyrotechnic sheet comprising a substrate of oxidizing polymeric film such as polytetrafluoroethylene (PTFE) coated with an oxidizable material, for example, magnesium.
Patent GB-2304973-A (GB)
Title: Interhead position offset compensation in disk drive/recording apparatus
Inventor: AHN YOUNG-SUB
IPC: G11B5/596
Filed: 1996-09-03
Abstract: Interhead position offset is compensated for in a data storage device such as a disk drive/recording apparatus having a plurality of heads and in which servo information is recorded on a data storage medium in an embedded sector servo mode. The servo information is sequentially sampled from a reference head and each other head. The servo information sampled from the reference head is used in track tracing and an offset value corresponding to the servo information sampled from each other head is stored. When head switching is required from a first head to a second head the position of the reference head is tracked off centre by an amount determined by the stored offset values for the first and second heads, before switching to the second head. By thus compensating for interhead offset prior to head switching, the head position settling time to the track centre line after switching can be minimised.

In an alternative embodiment a manually actuatable control cable is attached through suitable means to the drive shaft supported on the lawnmower housing between the drive wheel and the auxiliary trimmer apparatus to control engagement and disengagement thereof. Additionally, angular orientation adjustment means for the auxiliary trimmer assembly relative to the main rotation shaft axis of the lawnmower are provided to assure precise control of the width of cut afforded by the auxiliary trimmer apparatus.

The surface may be eg a ship's hull, a water pipe, a rope, a filter or a medical bandage.
Patent GB-2307949-A (GB)
Title: Rotary engine
Inventor: DOUGLAS JOHN LINDSAY
IPC: F02G1/00
Filed: 1996-11-08
Abstract: In a four stage rotary internal combustion engine rotors mesh 1-3 in a close fitting casing. The central rotor 2 has a hub carrying two ridges or pistons 6 which engage grooves 7 in rotors 1 and 3. A combustion chamber 5 is mounted outside the casing and is connectible via closeable ducts 12, 13 to a compression sector 8 and to a power sector 9 of the cylinder. A heat exchanger is incorporated in its wall. When running, air is inducted via manifold 10 and compressed in Sector 8. As the piston 6 reaches TDC the air is diverted into the combustion chamber 5 and the ducts close. Combustion occurs while the piston 6 passes TDC, then the ducts open allowing the gas into Sector 9 behind the piston. The heat exchanger may provide hot air to drive a hot air engine. More than one engine unit comprising combustion chamber and associated rotor may be used in parallel.

Patent GB-2312816-A (GB)
Title: Method and apparatus for decoding an encoded signal
Inventor: SCHAFFNER TERRY M
IPC: H03M13/27
Filed: 1996-10-09
Abstract: A decoder (215) implemented in a receiver of a wireless communication system employs an improved method and apparatus for decoding an encoded signal. The receiver sums the energy values (156A, 156B, ...156N) from a plurality of fingers within to produce an aggregate energy value (166). From the aggregate energy value (166), a set of log-likelihood values (207) are generated with a non-linear function generator (205) before being deinterleaved by a deinterleaver (210). The deinterleaved values (213) are input to the decoder (215) which estimates the original signal (178) by incorporating path histories of bits in the estimation of subsequent, related bits. Use of the path histories of bits improves the estimates of the original signal (178), which translates into an increase in the sensitivity of the receiver.

Title: Machine chuck
Inventor: VAN MULLEKOM ARNOLDUS PETRUS
IPC: B23B31/16
Filed: 1997-09-02
Abstract: A machine chuck 10 has a base 13 about a longitudinal axis. Jaw members 20 move relative to the base 13 and radially with respect to the axis. A scroll member 18 is mounted on the base for angular movement relative thereto, which scroll member 18 engages the jaws 20 to cause the radial movement thereof. The base 13 has an annular passage which receives pistons 17 attached to the scroll member 18. Fluid under pressure delivered to the passage 16 causes annular movement of the pistons 17 and therefore scroll member 18 relative to the base 13. This angular movement causes radial movement of the jaw members 20.

Title: A desmodromic gas exchange valve actuation arrangement
Inventor: GAGER CRAIG ANTHONY
IPC: F01L1/30
Filed: 1998-06-09
Abstract: A gas exchange valve actuation device for an internal combustion engine comprises a valve and a camshaft; the camshaft having a vane member, for maintaining the valve in a closed position by engaging a first groove formed on the valve, and at least one pin for opening and closing the valve by engaging a second groove on the valve. The first and second groove may be formed on a tappet which is connected to the valve. The path of the second groove is not coincidental to the locus of the pin as it rotates forcing the valve to move and hence provide the valve lift. A tight seal of the valve is maintained in the closed position by a spring positioned on the inside of the vane member. This compensates for engine heat expansion. The tappet is formed in two parts and is held together by a bolt (figure 2). Lubrication may also be provided by oil passages in the camshaft (figure 5, 6).
