Patent EP-0098000-A2 (EP)
Inventor: VIRDEE NIRMAL SINGH
IPC: H04B3/23
Filed: 1983-06-20
Abstract: A digital duplex communication system includes an echo canceller of the look-up table type. The echo canceller comprises a random access memory (RAM) (41), a digital to analogue converter (DAC) (45), a subtractor (5), adaption means (47), and an address generator (40). The echo canceller stores echo replicas for combinations of data bits transmitted by the transmitter (1) and subtracts these echo replicas from a received signal on line (9) before application to the receiver (2).The capacity required for the RAM (41) is reduced by storing only one echo replica for each of two complementary sets of data. To achieve this the address generator (40) is split into a primary address generator (73) and a complementary address generator (74) so that complementary sets of data present the same address to the RAM (41). The primary address generator (73) produces a signal to indicate which of the two complementary data sequences is being transmitted and appropriately sets the adaption means (47) over line (71) and a complementing circuit (70) over line (72). The combination of the signal on line (71) and the output of the subtractor (5) on line (12) causes the echo replica to be updated by the adaption means (47) which may be an adder circuit. The complementing circuit (70) operates on the output of the RAM (41) via the latch circuit (43) to determine the sign of the echo replica applied to the subtractor (5) via the DAC (45).

Title: Frequency synthesiser
Inventor: MCCANN KENNETH DAVID
IPC: H03L7/18
Filed: 1983-11-02
Abstract: A frequency synthesiser provided with frequency reduction means which includes a pulse swallow circuit PS which cancels cycles from the frequency Fo under the control of a rate multiplier RM. To prevent phase jitter at the output of phase comparator PC due to the cancelled cycles, a compensation signal HP is derived from the swallow command signal A and from the multiplying fraction n/x of the rate multiplier. In order to keep the DC level of the signal HP constant, the signal HP is bidirectional with respect to a mid-point voltage level and the total area of the pulses in one direction is the same as the total area of the pulses in the other direction. The invention is applicable to both phase locked loop synthesisers (Figure 2) and direct synthesisers (Figure 11).

Abstract: A wheelbarrow has a single wheel mounted to a foldable body having carrying handles and legs. The body has walls and is defined by a frame which is freely pivotable between an open erected position in which it supports the walls and a storage position. At least two opposed walls of the body are attached to the frame at one edge only and are pivotable from a substantially upright position in which they hold the frame erect to a position which allows the frame to fold. 
     The wheel axle is carried by a support which is rotatable with respect to the body to enable the wheel to be rotated to lie substantially parallel to the base of the folded body. In two embodiments described, the support is mounted on a rod which is rotatable with respect to the body through a bracket attached to or integral with the body. A lever attached to the rod at the rear of the body enables the wheel to be rotated from the normal operating position and a latch is provided to lock the lever when the barrow is to be used.

Abstract: With this method, which uses a superconducting analog-digital (AD) converter, the signals are coupled via a flux transformer (1) into a SQUID SQ1 (2) arranged as a null detector, which maintains the magnetic flux in the SQUID SQ1 (2) constant by means of a negative feedback circuit (3). For this purpose, a negative feedback flux  PHI 1 is coupled into the SQUID SQ1 (2) via a mutual inductance (M1), by a current I1 which is produced by a superconducting transformer (4) from a current I2 . This current in turn, after the critical current IC2 is reached, generates quantum leaps in a SQUID SQ2 (5) via a mutual inductance (M2). These are counted in a bidirectional counter (6) after being passed through an amplifier (7). The ratio of I1 to I2 is set by the superconducting transformer (4) and the mutual inductances (M1, M2) in such a manner that a variation  delta I1, which corresponds for example to the current resolution of the SQUID SQ1 (2), is produced by a current variation  DELTA I2, which in turn generates a flux quantum  PHI o in the SQUID SQ2 (5). I1 is here much smaller than I2 and the ratio of I1 to I2 is set at a fixed level and remains constant in time. <IMAGE>

Abstract: Digitizing and transmitting the maximum amplitude and time of occurrence of an analog signal is proposed for borehole televiewing apparatus to reduce the amount of data transmitted from a borehole tool to surface imaging equipment. During at least one established time window, the analog signal is amplitude sampled with an analog-to-digital converter 11. Each sample value is fed to a comparator 15 and compared with a previously stored maximum amplitude sample value and, if the present sample is greaterthan stored, it is stored as the new maximum amplitude sample value. Whenever a new maximum amplitude sample value is stored, its time of occurrence is also stored. At the end of each time window digital data representing the maximum amplitude and its time of occurrence are available fortransmission so as to allow reconstruction of the original analog signal.
