Patent GB-2047351-A (GB)
Title: Control of fuel injection systems for starting IC engines
IPC: F02N19/00
Filed: 1979-11-20
Abstract: At starting when battery voltage is low, the solenoid operated pump/injectors 10 are operated to supply the required fuel quantity in a number of reduced quantity injections so as to maintain a smaller solenoid air gap. Starter motor 58 is energised from a battery 59 by way of a time delay relay 60 which comes into operation when a starter switch 64 is actuated, control unit 62 being arranged so that energisation of the starter is delayed until the solenoids of all the pump/injectors have been energised to their maximum extent. When the cranking speed of the engine reaches a predetermined value the injectors are allowed to operate at about half stroke, each injector being operated at least twice to provide the required amount of fuel for starting purposes. Once the engine has started the system reverts to normal operation after a sufficient period has lapsed for the terminal voltage of the battery 59 to rise to a value such that the pump/injectors are capable of supplying the required amount of fuel in a single stroke requiring a large solenoid air gap. <IMAGE>

Title: Combustion products detector
IPC: G08B17/107
Filed: 1980-03-19
Abstract: A combustion products detector, such as a smoke detector, of the type utilising photo-electric detection of light from a light source 11 which is scattered by the, e.g., smoke particles, has the light source 11 connected in series with a transistor switch 22 across a power supply B+. Light from the light source 11 which is scattered by the smoke particles is detected by a photodiode 12 to operate an audible alarm 15. The transistor switch 22 is intermittently rendered conductive by a timer 25, and a capacitor 23 in parallel with the light source 11 and the transistor switch 22, is charged when the transistor switch 22 is non- conductive and discharges through the light source 11 to energise the light source 11 when the transistor switch 22 is conductive. A light emitting diode 20 connected in series with the capacitor 23 in the capacitor charging circuit is energised each time the capacitor 23 is charged to give a visual indication, the frequency of which indicates whether a fault exists in the capacitor discharge circuit and the nature of the fault. <IMAGE>

Title: Motor vehicle speed control holding devices
IPC: B60K31/02
Filed: 1980-04-01
Abstract: The speed control system of a motor vehicle has an electromagnet 1 or an armature 32 fixed to a part of the system so that the system can be fixed in a desired condition. A flexible cable 4 forming part of a speed control linkage may be fixed to the armature pulley 2. In operation, the pulley 2 turns in unison with the movement of the accelerator pedal. At any desired position the electromagnet 1 may be energised, locking the pulley and thus the speed control device. The electromagnet may be energised by a circuit-breaker type switch with a manual "off", a manual "on" position and an electrical release, preferably actuated by the brake light switch. Additional switching means could be provided to de-energise the electromagnet on depressing the accelerator. Alternatively, a combination of two relays in connection with push-buttons may be used to energise and de-energise the electromagnet. <IMAGE>

Filed: 1980-08-06
Abstract: An hydraulic power braking system (10) for a tractor vehicle (11) and trailer (12) has an automatic electro-hydraulic disengagement brake for the trailer. Brake lights (71), the magnet (35) of a valve (21) on the trailer (12), and a charging indicator light (63) are connected in current circuits which only pass through three contacts (45, 46, 47) of a multi-pole electrical plug-in coupling (43). All the circuits of the three loads (71, 35, 63) are associated, at least periodically, with the contact (47), whereas the remaining contact (46) not associated with the earth conductor can be connected to both poles (52, 49) of a battery (51) through a double switch (55) actuated by a brake pedal (13). Whereas the brake lights (71) illuminate with each actuation of the brake pedal (13), the charging indicator light (63) is only switched on during the various operating conditions when the hydraulic accumulator (25) is being relieved. The usual standard seven pole plug-in coupling used on tractors can be retained with the present disengagement brake. <IMAGE>

Title: Atomic absorption spectrophotometer
Inventor: STOCKDALE TREVOR JOHN
IPC: G01N21/31
Filed: 1983-06-06
Abstract: An atomic absorption spectrophotometer uses hollow cathode lamp assemblies (HCL1-HCL4) encoded by means of recesses and/or projections. The code represents one or more atomic elements corresponding to their resonant line(s). The presence or absence of the projections and/or recesses is read by corresponding code readers (CCR1-CCR4) feeding a microcomputer (MCP), which includes a microprocessor ( mu P) a read-only memory (ROM) and a read-write memory (RAM) to identify the elements. The read only memory (ROM) contains wavelength information at a location associated with each element, by means of which the microprocessor causes the correct operating current to be supplied by the lamp power supply (LPS) and causes the monochromator (MN) to be driven to the appropriate wavelength by the monochromator wavelength control (MWC). The projections and/or recesses may be formed in the lamp base or in a separate card attached to the lamp and inserted into a card reader.   <IMAGE>
