Title: Accelerometer noise signal reduction
IPC: G01V1/36
Filed: 1979-08-15
Abstract: A self-adjusting filter for use in an underwater seismic system of the kind that employs a towed body and peripheral equipment to produce profiles of the terrain beneath bodies of water. The filter receives from an accelerometer 14 located in the body an acceleration signal, including noise corresponding to the effect of gravity on the accelerometer, and reproduces the acceleration signal with an attenuated accelerometer noise signal. The filter accomplishes this by first generating 18 a correction signal proportional to portions of the accelerometer noise signal. A scaled correction signal is generated by a variable scaling device 20. The scale factor is made proportional to a correlation signal which is indicative of the correlation between the correction signal and the sum of the acceleration signal and the scaled correction signal so that signal components of the filtered acceleration signal corresponding to the portions of the accelerometer noise and to the correction signals tend to cancel completely. <IMAGE>

Title: Improvements in or relating to wind instruments
IPC: G10D7/02
Filed: 1979-12-06
Abstract: This invention relates to wind instruments and in particular to improvements to the support, fingering and mechanism of the flute family. In the prior art the air tube is straight resulting in an unnatural position of head and arms. Support and control of position is difficult and some digits notably the right thumb are not freely available to control note holes or keys. In the present invention the tube is disposed in an elongated loop with embouchure (5) note holes (6) and palm supports (8). The instrument is supported in a natural position in front of the body between the hands, acting in opposition, and the lower lip. All digits are thus freely available to operate note holes (6) or keys, and the mechanism and fingering system are significantly simplified. The configuration is compact and the larger instruments in the consort remain manageable by young players. A fipple mouthpiece can be used. <IMAGE>
Patent GB-2068659-A (GB)
Title: Control of electrostatic precipitators
IPC: B03C3/68
Filed: 1980-02-02
Abstract: High DC voltage and superposed pulses are supplied to a multi-section electrostatic precipitator. The pulse rise time and decay time are made short enough so that adverse sparking conditions do not develop. The DC base voltage is adjusted in coordination with the superposed pulse characteristics (voltage, frequency, and shape) to maintain an average current through the collected dust layer just below or at that value which would cause electrical breakdown of the dust layer. The pulses produce instantaneously very high ion densities and electric field strengths. Alternate sections only may be pulsed, with the other sections functioning as collecting sections. In other designs, all sections may be pulsed to provide sufficient current to hold the collected particles on the collecting surfaces and to prevent reentrainment. At least one of the sections may be a pulsed transmission line. <IMAGE>

Title: Workpiece transfer mechanism suitable for can making machines
IPC: B21D43/05
Filed: 1980-02-13
Abstract: For moving metal blanks and the progressively-formed can bodies made therefrom in a multiple draw can maker, between work stations in the can maker, a transfer mechanism is provided. Mechanism has sets of workpiece - engaging fingers (150) linked by bell cranks (149) to push/pull rods (147) jointly movable by a reciprocal shuttle (145), the bell cranks (149) being carried by two bars (148) fast with a reciprocal chassis (143) which has the shuttle (145) displaceably mounted thereon. An oscillatory drive transmission (141, 139) is provided for moving the shuttle (145) upon the chassis (143), and likewise a similar transmission (136) for the chassis (143). Movement of shuttle (145) relative to chassis (143) rocks the bell cranks (149) and causes the fingers (150) to grasp or release workpieces at the work stations, while joint movement of shuttle (145) and chassis (143) merely displaces the bell cranks (149) without rocking them and so causes the fingers (150) to move to or fro between the work stations. <IMAGE>

Title: Systems for firing propellant charges
Inventor: FITZ PHILIP JOHN
IPC: F41A19/63
Filed: 1980-07-07
Abstract: The problem of vent hole sealing in breechloading guns is overcome by arranging to fire the charge by a system in which the gun obturator bolt 17 is modified to enable it to act as electric, magnetic or, especially, electromagnetic field producing means operatively connected to a source external of the gun breech 10, whereby energy sufficient to cause the charge 11 to fire is induced into an electrical ignition circuit within the charge 11 itself. For electromagnetic fields the central portion of the bolt consists of a dielectric tube with a conductive core 52. For electric fields the bolt is separated from the breech block 12 by an insulating sleeve. For magnetic fields the bolt is non-magnetic but contains a magnetisable insert and is disposed in a coil. <IMAGE>
