Title: Wireless table-top conference system uses Balanced Mode loudspeaker
Inventor: READ ALLAN
IPC: H04R7/04
Filed: 2008-06-26
Abstract: A tabletop wireless conference or congress system comprises at least one audio loudspeaker enclosure which includes a single unconventional loudspeaker 4 with a very wide audio dispersion pattern e.g. a balanced mode radiator or a loudspeaker with an inverted cone, mounted facing upwards, together with a wireless audio receiver 7, amplifier 6, battery pack 8 and without external connecting wires. This enables it to be placed in the centre of a table around which anyone seated will be within the listening area (5, fig 2) without the need for additional baffles or shaped mouldings to direct the sound. The audio signal is received from an external master audio transmitter module (3, fig 2). Any number of wireless loudspeaker enclosures can then be employed within a given area providing they all fall within range of the master transmitter. The enclosure 4 may also include a microphone (10, fig 4).

Title: Synchronizing Digital Audio and Analog Video from aPortable Media Device
Inventor: HOLDEN PAUL
IPC: H04N7/52
Filed: 2008-08-20
Abstract: A portable media device (PMD) produces an isochronous (synchronized) audio/video experience when the PMD provides a digital audio signal to an accessory, e.g. an audio amplification system, while displaying analog video on an accessory-independent display. Delay characteristics of each instance of the accessory system (e.g. amplification stages) are measured (<B>305</B>) and stored in the accessory (<B>310</B>) as latency information. Synchronicity is established by the accessory providing the audio latency (delay) information to the PMD (<B>320</B>). This allows the PMD to delay a video portion of the presentation relative to providing the digital audio signal to the accessory, based on the audio latency information (<B>335</B>). As a result, the presentations of the audio and video portions are synchronized.

Title: Improvements in or relating to jet propulsion engines
IPC: F02K1/12
Filed: 1953-04-14
Abstract: 726,591. Jet-propulsion nozzles. UNITED AIRCRAFT CORPORATION. April 14, 1953 [April 26, 1952], No. 10140/53. Class 110 (3). A propulsion nozzle for a jet propulsion engine comprises a series of overlapping flaps pivotally attached to the downstream end of a convergent duct, a divergent duct,attached to and downstream of the convergent duct and means for moving the flaps outwardly to form a smooth wall between the convergent and divergent ducts and inwardly to form a convergent propelling nozzle. The propulsion nozzle shown comprises a convergent duct 14 which carries a supporting ring 12 and a divergent duct 20 downstream of the ring 12. The ring 12 supports a number of pivoted overlapping flaps 18 which are actuated by a ring 36 through links 38. The ring 36 is operated by a piston 50 in a cylinder 52 to which fluid under pressure is introduced by tubes 54, 56. In the position shown in full lines, the flaps 18 form a convergent nozzle at the end of the convergent duct 14. This position is used when the flow in the duct is subsonic. When the piston is forced to the other end of the cylinder 52, the flaps 18 are moved to the position shown dotted in which they form a part of the inner surface connecting the convergent part 14 and divergent part 30 of the duct. This position is used when the flow is supersonic. The flaps 18 have curved plates 66 which seal the gaps between the flaps as they are moved to the open position. The actuating ring 36 is supported by flutes 62 in the outer casing 64 of the duct. When the exhaust duct is used with a turbo-jet engine with reheating in the duct, cooling air is supplied to the flaps 18 from the compressor of the engine. This cooling air flows over the inner surface of the flaps 18 and divergent duct 20 as indicated by the arrows. Some of this cooling air may flow through the hollow flaps 18.

Title: Improvements relating to the production of coloured image displays
IPC: H04N9/27
Filed: 1966-03-08
Abstract: 1,139,674. Colour television. INTERNATIONAL POLAROID CORP. 8 March, 1966 [8 March, 1965], No. 10163/66; Heading H4F. A subject is analysed to determine the distribution of light in three different visible wavelengths and is reproduced by three visible displays in registration, the first being in white light and corresponding to the light distribution in a first of the wavelengths, the second being in coloured light and corresponding to the light distribution in a second of the wavelengths and the third being in a coloured light including the colour content of the second display and corresponding to the light distribution in the third wavelength. The invention is described in detail only as applied to television in which the displays are produced by a cathoderay tube having a screen formed of superposed red, green and blue phosphors and arranged whereby the electron beam velocity may be controlled so as to cause the penetration and excitation of one, two or three of the layers to produce respectively light of one, two or three component colours. The light comprised of two components includes the colour of the light due to the one component. The light comprised of three components is white light. The phosphor layers may be arranged in any order and Figs. 3-8 illustrate alternative combinations of colour displays which may be produced in response to electron beam excitation. The receiver is constructed to respond to an N.T.S.C. signal in which the analysis of the original subject at the transmitter is in terms of red, green and blue light. In the figures the colours represented by the signals which modulate the beam intensity are indicated at the left-hand side and the colours of the light of the resulting displays at the right-hand side. The beam velocity is controlled by changing the potential applied to a conductive layer 62. The colours may be produced in a sequence at field, line or dot rate. Conventional "colour killer" circuitry may be incorporated in the receiver to cause the cathode-ray tube to operate at maximum beam velocity, and hence produce white light, when a black-and-white signal is received. The Specification refers to the following features without giving details: (a) the use of other than N.T.S.C. primaries for the analysis of the original subject; (b) a cathode-ray tube based on a strip screen with masking and not requiring changes in beam velocity; (c) electroluminescent displays. The invention depends for its operation upon the reproduction of "lightness distribution" as distinct from absolute brightness, reference being made to the articles "Colour in the Natural Image" by E. H. Land (Proc. Royal Institution of G.B., Vol. 39, No. 176, pp 1-15) and "The Retinex" by E. H. Land (American Scientist, Vol. 52, No. 2, pp. 247-264) for the theory of operation.

Title: Improvements in or relating to shock absorbing devices for motor driven vehicles
IPC: F16F9/16
Filed: 1927-04-13
Abstract: 281,596. Soc. Internationale Holverta. Nov. 30, 1926, [Convention date]. Buffers; fluid - friction vibration-dampers.-In an elastic suspension device for motor vehicles in which telescopic tubes enclose a helical spring and a cylinder and piston one way dashpot, a rebound spring is provided and the area of the passage for the flow of liquid is automatically reduced as the device extends. The outer and inner telescopic tubes b, a are connected respectively to the axle and to a bracket e on the frame d by ball joints and the helical spring g supports the weight of the vehicle. An inner cylinder h is fixed to the lower tube b and a piston rod i fixed to the upper tube a, passes through a stuffing box m in the end of the inner tube h. The piston con. sists of several washers k of different diameters slidable on the piston rod. An inner helical spring l checks excessive rebound. When the device is shortened, the piston rod moves downward freely, but the washers owing to the resistance of the liquid, do not follow this movement. During the rebound or lengthening movement, the washers abut against the end of the piston rod in succession giving increasing fluid friction resistance to movement. The upper end of the tube h is enlarged so that the dashpot is out of action when the piston reaches that end of the tube.
