Title: A procedure and apparatus for corrected reproduction of acoustic recordings
Inventor: BROCK-NANNESTAD GEORGE
IPC: G11B20/18
Filed: 1983-04-08
Abstract: The transfer function of the horn/soundbox combination used in an early acoustico-mechanical sound recording process (cylinders and discs) is determined by measuring the spectral content of the noise present in non-modulated grooves. The procedure is two-stage: a measuring phase which adjusts the replay equipment and a replay phase. Slow movement of the record during the measuring phase is suggested, permitting many time-slices over which to integrate the transfer function. Replay may also be slow, with the replayed signal being recorded on an intermediate record carrier and then reproduced at the correct speed which may be adjusted according to other criteria. One embodiment described uses a parallel frequency analyzer in a feed-back connection, in order that the noise of a sound recording appears as white noise at the output of the parallel frequency analyzer filter bank. Several embodiments describe the use of digital signal processing means. <IMAGE>

Patent GB-850192-A (GB)
Abstract: 850,192. Ignition systems. BENDIX AVIATION CORPORATION. Sept. 9, 1957 [Sept. 14, 1956], No. 28426/57. Class 7(4). [Also in Group XXXV] Ignition apparatus comprises a coil, means to subject the coil to cyclically varying magnetic flux to induce cyclically varying voltage in the coil, means to close the circuit through the coil at first and second periods spaced from each other in the cycle, two electrical discharge devices one of which is operatively associated with one end of the coil and the other of which is associated with the other end of the coil means operatively to connect the one discharge device to the one end of the coil at the end of the first period and means operatively to connect the other discharge device to the other end of the coil at the end of the second period. In Fig. 6 the current generating portion of the illustrated ignition and battery charging system is schematically indicated as a unit 37 having a connecting panel 39 through which connections are made to the spark discharge devices and to the external portion of the battery charging device. In a typical operating cycle for a two cylinder two-stroke cycle engine the following events take place: 0 degrees (position of motor flywheel)-at this point breaker assembly 27 is in closed position. Breaker assembly 29 now opens. This collapses the flux in the ignition coil 26 thereby inducing a voltage surge in the primary of transformer 45 such voltage surge is transformed into a high tension by transformer 45 so that the spark plug 46 discharges. 120 degrees-Breaker assembly 29 now closes, as a result current builds up in the ignition coil 26. 180 degrees-Breaker assembly 27 opens. This collapses the flux in the ignition coil 26 thereby inducing a voltage surge in the primary of transformer 52 so that spark plug 54 discharges. 300 degrees-Breaker assembly 27 closes and remains closed to 360 degrees (or 0 degrees) at which time a new cycle begins. Battery charging is provided by the coils 25. In some instances the coils 25 may be connected in series rather than in parallel. Where the current is to be used for heating or lighting purposes the rectifier may be dispensed with. The contact breaker assemblies 27, 29 are mounted on an annular stator supporting plate 20 of non-magnetic material such as aluminium. The combined magneto and generator is described (see also Group XXXV). Specification 850,193 is referred to.

Title: RF field generating and detecting arrangements
Inventor: BUTSON PETER CHARLTON
IPC: G01R33/343
Filed: 1985-06-05
Abstract: An arrangement for generating or detecting RF magnetic fields, more especially for use in nuclear magnetic resonance imaging apparatus, comprises arcuate sheets 1, 3, 5, 7 of non-magnetic electrically conducting material disposed at spaced positions around the curved surface of a cylindrical volume and having interconnections 35, (37) at their ends to provide closed loop paths for current flow embracing the axially extending gaps between the sheets. In each gap between the sheets there is a further member (27, 29, 31, 33) of non-magnetic electrically conductive material so that current flow in such a closed loop path induces, or is induced by a current flowing in the further member in a loop substantially parallel to the closed loop path current, but in the reverse direction. The further members 27, 29, 31, 33 thus act as parasitic elements and reduce concentration of current in the regions of the gaps, and render the field more uniform. In a modification the members 27-33 have a central slot and the input and output feeders 17-23 are connected thereto in a lieu of sheets 1-7. In a second arrangement the four arcuate sheets each have a complete or partial longitudinal slot across which a respective feeder is connected (Figures 5-7, not shown), whereby an opposed pair of sheets acts as further members for the other opposed pair. <IMAGE>

Title: Jet propulsion fluid duct
Inventor: WRIGHT ERIC
IPC: F02K1/70
Filed: 1987-04-07
Abstract: The large ducted fan gas turbine powerplants now being designed for use in the next decade, are capable of mass flows which are far in excess of that required for part of the flight regime. The physical dimensions by the fan duct of such a powerplant also creates problems by way of frontal area, the magnitude of which can only be reduced by making the wall structure as thin as possible. To this end and at the same time with a view to catering for the excess flow, the present invention provides a propulsive fluid duct (such as the fan duct of a ducted fan engine) having a downstream end portion 12a which is axially translatable relative to the remainder of the duct and which includes a plurality of flaps 20. Ram mechanisms 22, and a telescopic arrangement of channels 26, 28, with pins 30, engaging slots 32, enable the end portion 12a to be translated, translation of the end portion to be stopped, and thereafter the flaps 20 to be pivoted to a position in which they extend across the duct thereby reducing its cross sectional flow area. During rearward translation of the end- portion 12a a gap 38 opens up through which air from the fan duct can exit. <IMAGE>
