Title: Single axis locking tremolo assembly
Inventor: GRAY DEREK JOHN
IPC: G10D3/14
Filed: 1989-07-24
Abstract: A tremolo bridge assembly which rotates forwards and rearwards about a single axis (7) to lower or raise the pitch of a musical note, locks in a central position when not being operated to allow accurate tuning of the instrument's strings (6). The tremolo comprises two parts, bridge block (2) and anchor block (3), which rotate about the single axis (7) of a chassis (5).

Title: Deriving horizontal and vertical sync pulses from a three-level HDTV sync signal
Inventor: KIRSCHENSTEIN REINHARD
IPC: H04N5/10
Filed: 1989-10-12
Abstract: A method and a circuit for deriving horizontal and vertical frequency sync pulses from a three-level HDTV sync signal is described. Firstly the positive components (a, a') and the negative components (b) of the three-level signal (S) are derived by comparison with reference voltages in comparators 2 and 3. The horizontal frequency sync pulses (H) are then derived from the positive pulses (a, a') of the three-level signal (S) by logical combination with a second pulse signal (c). The vertical frequency sync pulses (V) are produced by linking the negative components (b) with a fourth pulse signal (d) in a D-flip-flop 17. Finally, the picture-frequency sync pulses (2V) are derived by linking the negative component (b) with the vertical frequency sync pulses (V) in a D-flip-flop 18. …<IMAGE>…

Title: Radiation detector having a defined field of view
Inventor: PARKER JOHN CAMPBELL
IPC: G01J1/42
Filed: 1989-11-14
Abstract: A radiation detector, including a photodiode, has improved uniformity of sensitivity over the field of view because the receiving surface is provided by an optical diffusing layer, and the field of view is defined by a baffle arrangement, each internal surface of which is reflective. The baffle arrangement also defines a volume and the diffusing layer conforms to a part of the volume adjacent to the apex thereof. The diffusing layer may be provided by material, initially in liquid form, solidified in situ within the baffle arrangement. The receiving surface may be provided within a receiving head of the detector, spaced from the photodiode. Radiation may be transmitted from the receiving surface, whether part of a separate receiving head or not, to the photodiode by an optical fibre. An assembly of four constituent detectors, each having three orthogonally arranged mirrors, may together define a hemispherically shaped volume.

Title: Liquid control apparatus
Inventor: CARR WILLIAM ANTHONY
IPC: E03F5/10
Filed: 1990-05-31
Abstract: A water retention and flow control tank is divided into a head development chamber (2) and a much larger retention chamber (3) by a baffle-weir (4) which provides an overflow from the head development chamber (2) to the retention chamber (3). The head development chamber (2) has an outlet (7) associated with a vortex flow controller (8), and there are non-return flap valves (10) which allow the retention chamber (3) to drain back into the head development chamber (2) whilst preventing substantial flow from the head development chamber (2) to the retention chamber (3). When there is e.g. heavy rainfall, the water level builds up very quickly in the head development chamber (2) and the vortex flow controller (8) rapidly reaches its operating head, ensuring that the water discharge from the tank is at a predetermined maximum flow rate for the maximum period of time.

Title: Eliminating cumulative thickness errors in a wound coil of plastics foil
Inventor: HALTER HARTMUT
IPC: B29C48/92
Filed: 1991-03-15
Abstract: Plastics foil (1) as produced e.g. extruded from a die (4), has systematic thickness errors comprising positive and/or negative thickness errors which are superimposed in a wound coil of the foil to produce a non-cylindrical coil configuration. A substantially cylindrical coil is produced by monitoring the contour of the coil (2) by a laser or mechanical means (8) for at least one layer of the coil, and using a computer (12) to derive the thickness error profile (Fig 2), and control an extrusion die adjustment means (5) to produce an inverse thickness error profile in the extruded foil, so that foil layers of the given thickness error profile alternate in the coil with layers having the inverse thickness error profile, until the coil is completed with an adequately cylindrical contour. The foil may be extruded as a flat foil, or as a tubular blown foil (7), which is flattened and slit into a pair of separately wound flat foils (1).   <IMAGE>

Title: Method and apparatus for removing packing from bales
Inventor: MAROM ABI
IPC: D01G7/00
Filed: 1992-02-21
Abstract: In a method for removing packing (wrapping) 2a, 2b (eg sacks) from bales of raw textile materials (eg cotton), where the packing is arranged between hoops and the surface of the bale, the hoops are first cut, in a packing free region, and removed. Once the hoops have been removed, the pieces of packing 2a, 2b are stripped from the bale. The hoops are cut by devices 4 and 5 and removed by a conveyor (8, fig 2b) and the bales are stripped by rotating stripping rollers 6a, 6b, which can move in the vertical direction of arrows K-N so that one extends beyond the top surface of the bale while the other extends below the bottom surface (fig Sc). With the stripping rollers in their extended position the bale is passed between them on conveyors 9, 10, stripping the remaining packing. The packing is removed from the roller, after retracting its teeth (6', fig 7a), by orientating it into a vertical position so that it may enter the hole (20a, fig 10b) of the arm (20, fig 10a). Packing may also be stripped with the rollers in the vertical plane (fig 4c) and from bales without a gap between the packing (fig 9a). <IMAGE>
