Patent GB-2344903-A (GB)
Title: Correlation techniques
Inventor: FOLEY BRIAN JOHN
IPC: G01S13/32
Filed: 1978-09-01
Abstract: A continuous wave radar may be modulated with a binary m-sequence and, on receipt, correlated with a similar m-sequence to improve out-of-range rejection. For improved performance longer sequences may be required. This invention achieves improved rejection, without a longer sequence, by reducing the positive bits of one of the signals to zero amplitude. The out of range rejection is traded for a loss of in-range sensitivity. For an inverted m-sequence the negative bits are reduced.

Title: Method and apparatus for controlling the supply of power to loads from a limited electricity supply
IPC: G01R21/00
Filed: 1979-03-16
Abstract: The current or power output from a limited electricity supply is continuously measured by a circuit 5 and compared with predetermined transient and steady threshold levels. If the measured level exceeds the transient threshold level, all interruptable loads 9 are disconnected by a microcomputer 7 which switches off the respective triac 10 in series with the load, and are subsequently reconnected one at a time when the transient condition has passed. If the measured level exceeds the steady threshold level, the interruptable loads 9 are disconnected one at a time according to a predetermined priority scheme, and the disconnected loads are subsequently reconnected according to the same or an altered load priority scheme. Under the load priority scheme, certain loads have a greater prospect of connection to the supply during a predetermined time period, but all loads are assured a predetermined minimum connection time. <IMAGE>

The heat outlets may be circulating hot water radiators or warm air ducts. The application to a central heating system in a hotel is suggested, wherein the temperature of a room may be kept at a high or a low level at different periods of the day and depending upon whether the room is occupied. <IMAGE>

Title: Paper spinning
IPC: B31F1/00
Filed: 1980-09-22
Abstract: In the production of a paper yarn a strip 3 of paper is drawn from a reel 2 and is dampened by passing under a roller 14 dipping into a trough 10. After passing through a squeezing device 7, it is led to a V-pulley 11 which produces a slight longitudinal fold in the strip. The strip 3 together with an optional reinforcing strand 5 drawn from a package 13 then passes downwardly through a rotary spindle 20 fitted at its lower end with a false twist device 21 and carrying a package 28 of binder material. The false twist applied by the device 21 passes upwardly through the spindle 20 and compacts the folded strip 3 which is caused to envelope the strengthening strand 5. The compacted and reinforced paper strip is encircled by yarn from the package 28 as it enters the spindle 20 and the wrapped yarn leaving the false twist device 21 is fed forwardly by rollers 30 and 31 and is wound into a package 32 by a winding head 34. <IMAGE>

Title: Method for manufacturing the substrate of an electrochromic display cell
IPC: G02F1/153
Filed: 1980-12-04
Abstract: In manufacturing an electrochromic display cell substrate the ionic conductor (5) is kept out of contact with the transparent conductive elements (2, 2b). In a first method a transparent dielectric (3) is deposited over the whole surface of the transparent plate (1) which already carries the conductive elements (2, 2b). It is etched through a protective mask which is then used for the deposition of the electrochromic material (4). In a second method a layer of electrochromic material (4) is deposited on the whole surface of the transparent plate (1) which carries the conductive elements (2, 2b). It is etched through a protective mask which is then used for the deposition of the transparent dielectric material (3). Both methods thus result in the conductive elements (2, 2b) being covered with a continuous layer formed from areas of the dielectric material (3) and the electrochromic material (4). <IMAGE>
