Patent GB-2077786-A (GB)
Title: A mat and similar fabrics made of textile fibres, treated for improved adherence, for use in plastic material structures
IPC: B29C70/08
Filed: 1980-06-13
Abstract: A mat or similar fabric made of textile fibres for use in plastic material structures, has filaments, hairs, swellings, surface discontinuity and generally speaking means of providing adherence for outer plastics layers, obtained both by weaving with threads made by spinning "flock" and by subjecting the mat to a suitable mechanical or chemical process. The object is to provide a mat for impregnation which has sufficient 'bulk' or 'hairiness' to be bonded to the plastics material, to prevent delamination upon the receipt of a heavy blow. The mechanical process may be carding, emery-polishing, teazling or bulking. As shown in Fig. 7, the fabric 17 may be passed between two rollers 28, 29 covered with pointed elements 26, 27, 30, 31 to produce surface hairs or filaments 23, 24. <IMAGE>

Patent GB-2071721-A (GB)
Title: Improved filter pleat spacing process
IPC: B31F1/32
Filed: 1981-01-12
Abstract: In the manufacture of pleated filters with concertina folds a strip of additional material 5 is folded in with the filter material 6 as the pleats are formed in a conventional folding machine. The bulk and resilience of the additional strip 5 tend to open out the pleats and restraining means 10, 11 limit this so as to obtain pleats opened to a desired extent. The pleats are then to be held in place by the application to the crests of the pleats of a curable material such as sodium silicate. This may be applied to both sides of the filter material to obtain a relatively inflexible filter, or to one side only to obtain a filter which may be fitted around a cylinder. The curable material may be cured by infrared radiation. <IMAGE>

IPC: C21D1/74
Filed: 1981-05-11
Abstract: A method for the temporary shutdown of a carburising installation, in which parts to be hardened are conveyed in succession through a heating-up zone, carburising zone, a perlitising zone if present, and a hardening-zone, comprises the following steps: the hardening zone is emptied of products, the conveying mechanism is brought to rest, the temperature in the heating-up, carburising and hardening zones is reduced to 600 DEG C to 800 DEG C and the operating-gas atmosphere is replaced by an inert-gas atmosphere. After the shutdown, the heating- up, carburising and hardening zones are brought to a temperature of 850 to 880 DEG C and the inert-gas atmosphere is replaced by the operating-gas atmosphere as soon as the zones have reached this temperature. When all the zones have reached the said temperature, the hardening zone and carburising zone are brought to the required temperature, whereafter the conveying mechanism is set in operation and the heating up zone is brought to the nominal temperature.

Title: Synchronising circuit for phase-locking repetitive signals, e.g. television signals
Inventor: ROBERTS ALAN
IPC: H03L7/099
Filed: 1982-03-31
Abstract: A television or video synchronising circuit 10 is designed to provide from clock pulses a burst-locked oscillator 16 (or input sync-locked flywheel oscillator for monochrome operation) output line waveforms defined in a generator 22 and which are accurately phase locked with respect to input line sync pulses at terminal 14. A horizontal counter 20 counts the clock pulses, and waveform generator 22 provides a line pulse once per cycle of the counter on a line 26. A phase detector 30 determines the phase error between these line pulses and input line syncs and applies it to an accumulator 32. In normal operation the accumulator is reset before each phase error measurement and a phase detector 34 determines when the error is of sufficient magnitude or persistence to require correction, whereupon mode switch 36 is switched into a correction mode and the error standing in the accumulator is loaded by gate 38 into the counter 20 as an initial correction. Then the accumulator 32 accumulates the residual phase error for 256 active lines as counted in counter 40, at the end of which period the error is averaged and loaded by gate 42 as a fine correction to the counter 20. <IMAGE>

Abstract: A combustion chamber head (34) of a gas turbine engine annular combustion chamber (24) has a circumferential arrangement of flared pots (36) each of which has an aperture (37) at its upstream end and opens into the annular combustion chamber at its downstream end. A swirler assembly (42) and a fuel nozzle (58) are positioned coaxially within each aperture to supply primary air and fuel into the annular combustion chamber through the aperture. A flared member (50) is positioned coaxially within each pot downstream of the swirler assembly and is spaced from the pot to form an annular chamber (56). A swirler assembly (38) positioned in each pot supplies cooling air into the annular chamber to give a swirling flow of cooling air around the outer surface (52) of the flared member. The cooling air discharged from the downstream end of the annular chamber flows tangentially from the flared member to cool the combustion chamber head. The invention is intended to provide more efficient cooling of the flared member, and may be applied to other combustion chambers i.e. tubular combustion chambers. <IMAGE>
