Abstract: Hot air from a fan-driven air heater is passed through a filter (4) and a valve (5) connected to the suction pipe (16). Prior to starting, all hot air is passed through and delivers heat to the suction pipe (16), the conduit (6), and the air cleaner (4). - In the conduit (6), is a component (9) which closes a flow valve (8) in a by-pass (7) when the main valve (5) is open. When the engine is turned over by the starter motor, a quantity of hot air dependent upon the starting speed is sucked into its combustion chamber. After starting, the air flow direction is reversed so that cold air is warmed on passage through the air filter (19) and on into the engine. (Provisional Basic advised week 84/45)(1/5)

Abstract: An infrared radiation detecting system comprises an optical imaging system (25) for receiving radiation from a field of view (23) and delivering that radiation to an image surface (16). A background limited detector unit (26) having a detecting surface ( phi ) located in a cold shield housing having a cooled aperture (13) is spaced from image surface (16) and a transfer lens system (24) is interposed to transfer infrared radiation therebetween. Lens system (24) is arranged to focus the radiation at the detecting surface ( phi ) of the detector unit (26) such that the focussed radiation field curvature coincides with the physical curvature of detecting surface ( phi ), to form a pupil which is coincident in space with the position of the cooled aperture (13) and to dimension the pupil to match the dimension of the cooled aperture (13). To achieve these effects the transfer lens system (24) is formed by four lens elements (A,B,C,D) of selected power, axial spacing, and refractive surface curvature.

Abstract: A heart stimulator is described which is capable of sensing and stimulating both the atrium and ventricle in a heart in such a way that a ventricular stimulation pulse is emitted either after a stimulated or spontaneous atrial event following the atrioventricular interval (AVI) or after the expiration of a minimum synchronous interval (MTR) following a stimulated or spontaneous ventricular event, depending on which interval elapses last. The function of the heart stimulator, when the atrium's spontaneous rate is faster than a stimulation rate corresponding to the minimum synchronous interval (MTR), is improved when it imposes an extra atrial stimulation pulse (27b) at a second predetermined atrioventricular interval (20d) before the next ventricular stimulation pulse (22c) if the interval between the most recently detected atrial event (19c) and the next ventricular stimulation pulse (22c) exceeds a predetermined threshold value. <IMAGE>
