Title: Sound generator
IPC: H04R17/00
Filed: 1977-08-10
Abstract: An open ended can has a piezoelectric crystal attached to its closed end face and contains within it the battery supply and circuitry operative to cause the can to resonate. The can is attached at its open end to a back board through a ring of closed cell foamed synthetic plastics material to form a waterproof enclosure for battery and circuitry. The circuitry is based on one or more CMOS integrated circuits having gates or inverters connected to form one or more oscillators and one of the oscillator pulses the crystal through a transistor power amplifier and step up transformer. That oscillator may be adjusted off the resonant frequency to reduce the output or a feedback path provided to lock the oscillator onto a resonant frequency.

Title: Exhaust valve for i.c. engine
IPC: F01L3/20
Filed: 1980-08-28
Abstract: In the stationary and/or the movable valve part (1, 4) of the exhaust valve there is provided an annular chamber (9) formed as a circumferential recess in the surface of the valve part (4) in question facing the other valve part. The annular chamber is located intermediate the seating surfaces (5, 6) of the valve parts and the combustion chamber (10) of the engine cylinder and it communicates with the combustion chamber through a relatively narrow inlet when the valve is closed. During the compression period of the engine cylinder's working cycle the annular chamber is filled by pure and relatively cool air, and if local gaps are present between the seating surfaces, that air acts as a barrier preventing the leakage of substantial amounts of hot and aggressive combustion gases through the gaps during the initial part of the expansion period. This prevents the valve parts from being subjected, adjacent to said gaps, to a high temperature rise and concomitant heavy corrosive attacks which would lead to a rapid enlargement of the gaps. The invention, therefore, prolongs the lifetime of the valve by delaying the moment when a refurbishing of the seating surfaces becomes necessary.

Title: Sampling gas for analysis
IPC: G01N1/00
Filed: 1975-10-24
Abstract: 1500508 Sampling gases BRITISH STEEL CORP 28 Oct 1975 [28 Oct 1974] 46432/74 Heading G1B A method for the rapid transfer of gas from a sampling probe at a source of the gas to a gas analyzer remote from the gas source, comprises passing the gas from the probe along a first gas sampling duct intercommunicating with a second gas sampling duct which transfers a gas sample to the gas analyzer, the first gas sampling duct being relatively long compared with the second gas sampling duct and the gas being transferred along the first duct at a high gas transfer rate relative to the transfer rate along the second duct, a proportion of the gas in the second gas sampling duct being vented to the atmosphere immediately prior to the analysis of the remaining gas. In an example a steelmaking vessel 10 is shown with a hood 11 and an oxygen lance 12. The hood draws the hod exhaust gases into a waste gas duct 14. Waste gas sampled through the probe 15 passes at about 56 litres per minute along a first sampling duct 16 through filter 17 and cooler 18 to vacuum pump 19. In the filter fume particles are removed, and in the cooler the gas temperature is reduced to ambient temperature. Beyond the pump 19 the sampled gas continues along the duct 16 at a positive pressure until the duct leads into an analysis room 20. The duct 16 passes through the analysis room and the bulk of the sampled gas is exhausted to atmosphere at 24. A second sampling duct 25 branches from the first duct 16 within the analysis room and part of the sampled gas is drawn along the second duct 25 and through a further filter 26 at about 5 litres per minute by pump 27. From pump 27 the second sampling duct leads through a further cooler 28, to remove any residual moisture in the gas, to three gas analysers e.g. a paramagnetic oxygen analyzer 31 and infrared analyzers 32 and 33 for carbon monoxide and carbon dioxide respectively. From these analyzers the gas is exhausted through a duct 35. The analyzers 31, 32 and 33 require a gas supply rate of about one litre per minute. A bleed line 36 is provided in the second gas sampling duct 25 prior to the analyzers to vent excess gas to the atmosphere. It is possible to operate the steelmaking process with a time lag of as little as 10 to 15 seconds between sampling the waste gas and obtaining an analysis of its oxygen, carbon monoxide and carbon dioxide content. Pump 19 transfers gas at about 56 litres per minute along duct 16 at a pressure of about 22mm. mercury gauge. Duct 16 is unrestricted and of 12À7mm. internal diameter. The second gas sampling duct 25 is of 6À3 mm. internal diameter and is provided with gas from pump 27 at a pressure of approximately 60 mm. mercury gauge.
