Patent GB-2065880-A (GB)
Title: Radiation Detector for a Fire Alarm
IPC: G01N21/00
Filed: 1979-04-24
Abstract: The radiation detector includes a radiation sensor which may be a pyroelectric element (4), e.g., lithium tantalate or lead zirconate titanate. In front of the sensor element (4) a filter combination is arranged, which consists of a quartz filter element (2) which may have a narrow-band filter layer (1) vapour-deposited onto it and which has a maximum transmission at about 4.3  mu m, as well as a germanium filter element (6). This filter combination shows a sharp maximum transmission at the resonance radiation from carbon dioxide at 4.3  mu m, whilst the whole of the other ranges of wave-lengths are damped by more than a factor 100, e.g., 1000. A fire alarm equipped with such a radiation detector responds extremely selectively to flame radiation but does not react to interference radiation such as sunlight or daylight, artificial sources of light and welding arcs, even when these exhibit an intensity of more than a thousandfold, so that flames of very low intensity may be detected surely, sensitively and without susceptibility to interference even in the presence of powerful interference radiation. <IMAGE>
Patent GB-2078886-A (GB)
Title: Improvements in fluid-pressure- operable relay valves
IPC: B60T15/18
Filed: 1981-06-16
Abstract: In a fluid-pressure-operable relay valve a control piston (6) works in a bore (2) in the valve housing (1) in response to control pressure at port (12) to control sequential communication between an inlet port (14) and an outlet port (15), and between the outlet port (15) and an exhaust port (4). An exhaust valve seating (22) on the control piston (6) is engageable with an exhaust valve member (21) coupled to one end of a lever (23) pivotally mounted in the housing (1), and a spring (26) acts on the exhaust member (21) to urge an inlet valve member (19) towards an inlet seating (20) surrounding the inlet port (14). Since the spring (26) acts in opposition to fluid pressure at the inlet port (14), a relatively small 'cracking force' is required to urge the inlet member (19) away from the inlet seating (20) to open the inlet valve. In alternative constructions (not shown) the inlet and exhaust members are combined into a single valve member which is urged directly by the spring towards the inlet seating. <IMAGE>
Patent GB-2081856-A (GB)
Title: Method of and apparatus for improved combustion
IPC: F23M9/00
Filed: 1981-07-10
Abstract: A method of and an apparatus for obtaining better utilization of a fuel 1a, especially a solid fuel, in which the fuel is subjected to a primary combustion in a primary combustion chamber 1b and the primary flue gas with entrained particles of combustible material flows through a restricted outlet 1c into an after-combustion chamber 2. In the chamber 2 the particles are separated from the flue gas by a combination of sedimentation, resulting from the expansion of the flue gas into the larger flow cross section of the chamber 2, impingement-baffle separation and of direction-change separation, the two latter forms of separation being caused by impingement of the flue gas against a baffle 4 disposed above an outlet 3 to the chimney or stack. An inclined wall 6 in a dead space or flow shadow region in the chamber 2 serves to guide the collected particles back to a combustion region, at which a burner 7 is optionally provided. <IMAGE>

Title: Throttle control device
IPC: F02M19/12
Filed: 1981-02-24
Abstract: A throttle control device for automobiles using internal combustion engines is mounted adjacent the accelerator pedal (21) and is connected to the engine intake vacuum by a hose (19). The vacuum operates a diaphragm (8) in the device to release a retractable spool (3) for rotation when the vacuum pressure is sufficiently high and above a predetermined level. A wire (16) wound on the spoll (3) extends from the device and is connected to one end of a spring (17). The other end of the spring (17) is connected to the accelerator pedal (21). Thus when the vacuum is above said predetermined level the accelerator pedal (21) may be depressed without any noticeable extra effort. When the vacuum falls below said level the diaphragm (8) causes locking of the spool (3) against rotation and the force of the spring (17) must be overcome to depress the accelerator pedal (21) further.
