Inventor: AUTAGE ROGER
IPC: F02B3/06
Filed: 1985-08-14
Abstract: The invention provides a process of adjusting the cetane rating of a fuel during continuous production thereof, comprising the steps of supplying a measuring Diesel engine with part of said fuel, determining the combustion pressure of said fuel in said engine by means of a combustion pressure pick-up, analyzing the signals produced by said pick-up to deduce therefrom the value of the cetane rating of said fuel, and adjusting the composition of said continuously produced fuel while taking into account the difference between the measured cetane rating and the required value thereof. The composition may be adjusted by selective mixing from reservoirs 1 to 4 of fuels of different ratings. <IMAGE>

Title: Intruder detecting fences
Inventor: PEPPER ALAN JOHN
IPC: G08B13/12
Filed: 1985-08-19
Abstract: A fence comprises a plurality of posts interconnected by a filament, and means for detecting a change in the tension of the filament. In one form a mechanical trip switch is sensitive to increase or decrease of tension to change its state, in which changed state on electric or optical sensor is operated. Preferably the trip switch moves an optical diaphragm located between the ends of adjacent optic fibres. In an alternative form, an optic fibre is abraded (whereby its transmissivity is changed) upon change in tension of the filament. The filament may be constituted by the optic fibre itself. The filament may be housed within a coaxial flexible sheath, which sheath comprises the visible fence wire. <IMAGE>

Patent GB-2178307-A (GB)
Title: Body support device
Inventor: DE HAMEL MARK ETIENNE BRUNO
IPC: A47C23/00
Filed: 1986-07-17
Abstract: A body support device, for example a bed, is formed from a plurality of swivel elements able to pivot in any direction by a limited amount and a grid system of interconnected fluidic cell units. Each cell unit comprises a connecting rod connected by a swivel joint to the swivel element, a piston which may be incorporated in the connecting rod or may be a separate element, and a fluid chamber fluidically connected to the grid. Application of body pressure to the device causes some swivel elements to depress which directly or indirectly activates the piston to expel fluid from the chamber into the grid, the fluid pressure in the grid being used to support the body when a position of equilibrium has been reached. "Bottoming out" resistors are provided to cater for excessive weights to prevent the pistons reaching the bottom of the fluid reservoir, and various means of absorbing shocks caused by sudden application of pressure on the device are disclosed. <IMAGE>

Title: Trimming a resistor
Inventor: BRODIE DUNCAN GEORGE
IPC: H01C17/24
Filed: 1987-05-29
Abstract: An electrical resistor, particularly for protecting telecommunications equipment from spurious high voltages produced, for example, by lightning comprises a planar insulating substrate (1) having a film resistance element (4) thereon. Electrically conductive terminations (2, 3) for the element (4) are located at opposite ends of the substrate (1).

Title: Motor apparatus for a control valve
Inventor: BENNETT BRIAN
IPC: H02P7/00
Filed: 1987-06-22
Abstract: A motor is connected to a reversing switching and a rechargeable electrical energy storage device such as a high value capacitor (SC1, SC2). On application of power to the apparatus (ie. during normal operation), the motor can be driven in forward and reverse directions to drive a valve, and on removal of power from the apparatus, charge stored in the storage means drives the motor to bring the valve to a rest position. The apparatus is self-contained, and avoids the need for an over dimensioned motor which would be necessary to drive against the normal self-return spring. <IMAGE>

Patent GB-2200190-A (GB)
Title: Fluid filled power unit mount
Inventor: TABATA TOSHIYUKI
IPC: F16F13/00
Filed: 1987-12-22
Abstract: An elastic support member 16 is securely disposed between inner and outer cylindrical members 12 and 14 which are respectively connected to a power unit and a vehicle body. The support member 16 has a hollow 36 a part of which serves as a main fluid chamber 50. A diaphragm member 52 is secured to the inner peripheral surtace of the outer cylindrical member 14 to define an auxiliary fluid chamber 54 which communicates through an orifice passage 34 with the main chamber 50. The diaphragm member 52 operates independent of the support member 16, thereby enabling damped vibration frequencies to be tuned within a low frequency region corresponding to engine shake and/or idling vibration, regardless of the rigidity of the support member 16. Other embodiments show various throttle arrangements for the orifice passage, and the diaphragm can carry a mass member.

Title: Flame detector
Inventor: POWELL BRIAN DAVID
IPC: G06V10/40
Filed: 1988-10-12
Abstract: A flame detector has a sensor for producing a digital waveform (4A) representing the flickering flame. Its turning points are detected and the magnitudes 30A, 30B, 30C..., between successive such points are measured. The value of each such magnitude is plotted on a graph (4B) whose horizontal axis represents the current value and whose vertical axis represents the immediately preceding value. Points such as E and F are produced lying in regions away from the diagonal B and from the axes. If the detected waveform originates from a regularly varying interfering source, the corresponding points will lie on or near the diagonal B. If the interfering source is a waveform undergoing step changes, the corresponding points will lie adjacent to the axes. In this way, discrimination between flames and interfering sources of radiation can be made. <IMAGE>
