Patent GB-2154907-A (GB)
Title: Finishing pile fabric
Inventor: OTTING DAVID L
IPC: D06B21/00
Filed: 1985-02-19
Abstract: A continuously moving carpet pile fabric (12) is treated to bulk the pile fabric and thereafter to dye the pile and fix the dye without the use of steam. The bulking occurs by passing an electrical current through carpet wetted with an electrically conductive liquid to explode or bloom the carpet pile fibers, the bulking being performed in station (20) including an electrode arrangement (30). The dyeing process employs a dye applicator (22) to which a heated dye solution is supplied. The dye is pumped through a heat exchanger (120) (Fig. 2) prior to entering the dye applicator and thereafter dispensed onto the carpet (12) at a temperature sufficient to fix the dye instantly, the temperature being below the boiling temperature of the dye. Manifolds (80,81) and piping (136,138,144) associated with the dye applicator permit the dye to be recirculated back to the supply side and provide consistent coloration across the carpet by stabilizing the dye solution. Additional piping (136,138,140,142) permits by-passing some or all of the dye around the dye applicator. The process permits the elimination of dye fixing steamers now universally used in dyeing continually moving textile webs. <IMAGE>

Title: Measuring distortion in signal processing equipment
Inventor: BROADHURST ANTHONY D
IPC: G01R23/20
Filed: 1986-07-10
Abstract: The magnitude of distortion caused by sound and television equipment is measured by determining the average magnitude of the distortion component during a number of short time periods. Thus, the magnitude of intermodulation distortion caused by TV equipment is measured by generating, 18, a local signal that has a frequency of 200 Hz greater than that of the intermodulation distortion component and mixing, 16, the local signal with the demodulated output of a test pattern supplied to the equipment only during a time window of 1,8 microsecond duration, from generator, 36, then filtering out the 200 Hz difference by means of a 500 Hz lowpass filter, 22, and determining the magnitude thereof. The process is repeated a suitable number of times with the window being generated repeatedly every alternate line (for a PAL system) during a particular part of the test pattern, with the determined magnitude being averaged, 26. <IMAGE>

Patent GB-2197461-A (GB)
Title: Method and apparatus for spectral measurement
Inventor: CARROL JOHN EDWARD
IPC: G01J9/04
Filed: 1986-10-24
Abstract: A technique for the measurement of the spectral lineshape (amplitude and frequency stability) of an electromagnetic radiation source eg. a semiconductor laser (1) involves the comparison of an input signal (A) and a reference signal (B) which are frequency offset by a pre-determined amount ( DELTA f). Signals output from a comparator stage (5) are integrated for a given interval of time and sampled to provide a set of correlation coefficients. As described the comparator (5) comprises a 4 x 4 multiport fibre-coupler junction (Fig. 2 not shown), producing complex amplitude products of the two signals, with quadrature phase. Frequency offset device (7) uses a coiled optic fibre bonded about a piezoelectric crystal driven by a sinusoidal voltage. Frequency offset selection and integration timing may be controlled by microprocessor or computer. The method above may be used to study semiconductor lasers (1) in terms of noise processes. Of particular interest is the correlation between amplitude and phase noise. <IMAGE>

Title: Ventilation control with rate of change response to humidity
Inventor: SHAW GORDON WESTBROOK
IPC: F24F11/00
Filed: 1988-07-20
Abstract: A control device for ventilation apparatus provides a switching signal which is dependent on the rate of change of humidity in a ventilated building or room space. A humidity sensor (10) is coupled to a circuit arrangement in which the output of the sensor is applied to signal paths (12, 14) for generating signals which are linearly related respectively to the level of the sensor output and to the derivative of that level. These signals are summed in a combining stage (16) and a comparator (19) yields a switching signal according to relative magnitudes of the combining stage output signal and a reference voltage. An inhibitor circuit (18) suppresses the effect of a negative derivative resulting from rapidly falling humidity so as to avoid rapid switch cycling. Ventilation apparatus incorporating the control device of the invention can be set up to respond quickly to an increase in humidity while being largely insensitive to high external humidity levels. <IMAGE>

Title: Extrusion die for blown plastic film
Inventor: GATES PETER CLIFFORD
IPC: B29C48/10
Filed: 1988-10-19
Abstract: In an extrusion die, liquid polymer is conveyed from a central supply duct, through conduits and feed channels, to the conventional set helical grooves. Each groove is fed by a pair of main feed channels, and one or more subsidiary feed channels, the latter being positioned between the main feed-channels. The feed channels are fed from the conduits in such a manner that the hot liquid from the middle of the main supply duct appears along the walls of the groove, and the cooler liquid from the walls of the central supply duct is broken up and dispersed in the middle of the stream flowing up the groove. The effect is to create more uniform temperatures in the polymer as the polymer enters the helical grooves than has been possible hitherto. The invention leads to a more homogeneous film, which allows the production rate to be stepped up. One benefit is that hard -to-extrude materials such as high-density polypropylene can be accommodated. <IMAGE>

Patent GB-2218539-A (GB)
Title: Central heating controller
Inventor: HEEKS THOMAS RALPH
IPC: F24D19/10
Filed: 1989-04-14
Abstract: A central heating controller has preset programs defining the start and finish of two switching periods during which the heating is controlled to a preset temperature. Two rocker switches 2 and 3 enable the switching periods and temperature to be temporarily modified. Actuation of one switch 2 during the switching period brings forward or delays the end of that period by one to three hours according to the number of times the switch is actuated. When operated before the switching period has commenced, the switch 2 causes the controller either to delay the start of the next switching period, or to commence an additional switching period. Actuation of the other switch 3 during a switching period modifies the preset temperature of the switching period; if actuated outside the switching period, the temperature of the next period is modified. After the modified period has expired, the controller reverts to its original program without further actuation of either switch. The controller is of general application, application to lighting being mentioned. <IMAGE>
