Title: Reception of orthogonal frequency division multiplexed signals
Inventor: GLEDHILL JEFFREY JOHN
IPC: H04N7/24
Filed: 1991-09-13
Granted: 1994-02-17
Abstract: PCT No. PCT/GB91/01571 Sec. 371 Date Jan. 7, 1993 Sec. 102(e) Date Jan. 7, 1993 PCT Filed Sep. 13, 1991 PCT Pub. No. WO92/05646 PCT Pub. Date Apr. 2, 1992.In an OFDM signal individual OFDM carriers are modulated by samples of signals which can only take a limited range of allowed values and a block of samples modulates the group of carriers during a time period T. In a receiver, the signal modulating an individual OFDM carrier may be demodulated by estimating the position of reference axes serving as the frame of reference against which the allowed modulating values are defined, and multiplying the value of the demodulated samples by the complex conjugate of a point on one of the estimated reference axes. The spread of the groups of samples demodulated from each OFDM carrier gives an indication of whether the receiver is synchronised to the block boundaries. Preferably spread of the complex samples is evaluated in the radial direction only and used to steer the sample clock frequency. Phase drift of the demodulated samples from one block to the next indicates the degree of local oscillator frequency error. Preferably phase drift is assessed by multiplying complex values by the complex conjugate of an earlier sample demodulated from the same OFDM carrier and using the resulting measure to steer the local oscillator frequency via a frequency locked loop.

Patent DE-1902247-B2 (DE)
Title: Displacement transducer transformer system - has error cancelling windings and has twin multiphase stator windings with sine and cosine sections
IPC: G01D5/20
Filed: 1969-01-17
Abstract: The displacement transducer transformer comprises two multi-phase windings which move relative to one another as stator and rotor. The stator consists of a base plate (3) onto which is stuck an insulated disc (4) carrying one set of windings. A second set of windings (6) lies over this, similarly insulated by a thin plastics foil. The rotor (11) carries one insulated disc (12) containing a winding. Each of the three windings contains a number of sections divided into radial strips. The winding sections of each of the stator windings alternate as sine windings (even numbers) and cosine windings (odd numbers). The two stator windings are staggered with respect to each other so that the sine winding of one coincides with the cosine of the other and vice versa. This arrangement produces a high degree of compensation for error normally associated wiht multiphase windings.

Patent DE-2406130-B2 (DE)
IPC: G04F5/06
Filed: 1974-02-08
Abstract: A temperature compensated electronic timepiece comprises a time reference signal generator for generating a time reference signal and a temperature compensating device for compensating a change of the oscillating frequency of the time reference signal generator caused by any external temperature change. The temperature compensating device comprises a temperature detector having an element composed of two semiconductors of different respective conductivities (such as a transistor composed of P and N type semiconductors) which are joined to form a junction, or an element composed of a conductor and a semiconductor joined to form a junction. The voltage-current characteristics of the junction are changed when the external temperature exceeds a given temperature to deliver a digital signal whose state is reversed from an initial condition. The output signal from the temperature detector compensates any temperature change of the oscillating frequency of the time reference signal generator.

Title: Method and apparatus for ageing spirits such as whiskey
Inventor: MOONEY PATRICK ROY
IPC: C12H1/22
Filed: 1997-03-13
Abstract: A method for ageing spirits, particularly whiskey, includes removing a generally matured whiskey from a first wooden cask and transferring the matured whiskey to a supplementary container (50) for storage and further maturation. The supplementary container (50) includes a wood component (65, 75, 80, 85) for the continued maturation of the whiskey contained therein. The container (50) comprises a bottle having a body (53) through which a wood component (65, 75, 80, 85) is passed and fixed thereto. The wood component (65, 75, 80, 85) thus has a surface exposed to the maturing whiskey and the air surrounding the bottle. This facilitates the natural evaporation of whiskey components to simulate the evaporation phenomenon of wooden casks. The wood components (65, 75, 80, 85) are shaped to increase the surface area available for contact with the maturing whiskey.

Abstract: A subscriber line access circuit for use in a telecommunications system is disclosed. The subscriber line access circuit includes a power supply bridge in the form of a first resistor inserted in the b-wire (ground potential side) of a subscriber line, a second resistor inserted in the a-wire (supply potential side) of the subscriber line, and a capacitor which bridges the two wires at the terminals of the two resistors on the sides thereof opposite to the respective potential sources. This supply bridge is coupled on the capacitor side with a two-to-four wire hybrid transformer for the two-wire/four-wire transition to the system and includes an evaluating circuit which delivers an indicating signal when the subscriber actuates a ground key. A cutoff circuit is arranged in the power supply bridge between the first and/or second resistor in that bridge and the respective one or ones of the transformer windings at the junction points at which the evaluating circuit is connected. The device for generating call signals is connected to one of these junction points via a coupling contact and a series resistance. The associated cutoff contact of the supply bridge and the coupling contact of the call signal generating device are controlled in such a way that they can be closed only alternatively.

Abstract: Bolt anchored by impact for insertion in undercut drilled holes in masonry are known, which have an expanding body supported on the base of the drilled hole, onto which an expanding sleeve can be driven. These conventional bolts anchored by impact cannot be used in drilled holes which are not undercut, at least in relatively hard masonry. In order to provide a bolt anchored by impact which can be inserted in both undercut drilled holes as well as drilled holes without an undercut, in a positively locking manner, there is provided on the shank end of the bolt anchored by impact a plate with a cut-out whose side limbs can be spread in a V-shape by driving in an expanding body. The narrow edges of the plate can in this case bury themselves in the wall of the drilled hole and produce a positively locking connection to the masonry. <IMAGE>
Patent JP-H0672919-B2 (JP)
IPC: G01S7/52
Filed: 1984-03-13
Abstract: A method and apparatus for processing ultrasonic echo signals employ intermediate storage and representation of the echo signals in the form of image vectors, such storage and representation proceeding independently of the scanning technique utilized to generate the image vectors, such that switching among various scanning techniques is permitted. The full length of each image vector is written into an image memory in column fashion, the stored vectors being read out as image signals in a format suitable for specific types of representation, such as on a television monitor, the format instructions being contained in a memory or generated by an arithmetic unit. Upon read out from the image memory, the geometric form of the ultrasonic scan is reconstructed in a position and form corresponding to the actual scan, and the ultrasonic echo signals are similarly represented at their true positions.
