Abstract: 1530126 Power plant; gas engines A J OXLEY 22 Dec 1975 [23 Dec 1974] 55493/74 Headings F1Q and F1S When a power plant is producing excess electrical power beyond the demand, the excess power is employed to drive an air liquefier 19 e.g. a Sterling refrigerator, the liquid N 2  and O 2  then being stored for driving an engine 27 e.g. a Stirling engine during peak demand to produce extra electrical power. Liquid nitrogen is supplied to the cold end of the Stirling engine whereas the hot end is heated by exhaust gases from a furnace/boiler 14, 17 which produces steam to drive the primary power generating turbine 12 or by the steam exhaust from the turbine 12. Liquid O 2  may also be used to cool the Stirling engine via a heat pipe 31, or to precool the air feed to the refrigerator, or to enrich the combustion air for the furnace 17. Instead of, or in addition to driving the Stirling engine, liquid nitrogen may be vapourized by ambient air or by heat exchange with water from a condenser 45 and expanded through a turbine or a reciprocating piston engine (not shown).

Abstract: 1329127 Oil burners J A RYDBERG 2 Dec 1970 [5 Dec 1969] 57255/70 Heading F4T An oil burner, comprising an oil injection nozzle arranged perpendicularly to a transverse wall and provided with an annular series of holes radially spaced from the nozzle axis through which the greater part of the combustion air is supplied, has an annular air supply passage means adjacent to the transverse wall and extending around the nozzle, to which additional combustion air is fed to form a veil of cleansing air along the wall to prevent the formation of soot. The burner, Fig. 2, has an oil injection nozzle 2 placed in a cylindrical cup 8 sunk into a transverse wall 1. Main combustion air is supplied through a series of holes 4 and additional combustion air through a slot 9 formed between the cup 8 and wall 1. The veil of air blows soot off the wall 1. Air ports 11, 12 prevent the deposit of soot in the cup 8. Air may also be blown in tangentially near the top opening of the cup. In a modification, Fig. 3 (not shown), the inlet of the cup 8 is provided with a cylindrical or frusto-conical enlargement. The cup 8 may be fruato-conical. In a further modification, Fig. 4 (not shown), the annular air supply passages discharge radially inwards. The oil injection nozzle may atomize the oil by the use of high pressure oil or low pressure oil mixed with air vapour, or compressed air or by the use of rotary nozzles. The air jets through holes 4 suck hot combustion gases back from the combustion space to the area adjacent the transverse wall.

Title: Electric motor driven vehicles
IPC: H02P3/12
Filed: 1970-12-08
Abstract: 1381856 Control of electric motors CABLEFORM Ltd 6 March 1972 [8 Dec 1970] 58177/70 Heading H2J To dynamically brake a motor for a vehicle when the motor is de-energized, one of the motor field windings is energized, from a permanent magnet generator coupled to the motor. Dynamic braking may also be applied when the motor is energized and exceeds a preset speed, as selected at the generator output. In a motor control of a fork lift truck, having an armature 2 and a series winding 3 fed from a battery 1 through a reversing switch 7 and D.C. switch 5 which is pulse controlled to vary the mean power to the motor, the output of a permanent magnet generator 8, mechanically coupled to the motor, is detected by relay 9. which is energized at a predetermined generator output i.e. motor speed, to close contacts 10. This allows current to flow to an additional motor winding 4 from the generator 8 through resistor 11, which determines the amount of dynamic braking current through diode 6. The braking is stopped when relay 9 is de-energized i.e. at a preset lower speed, which may be zero. When the motor is at a halt and the motor is de-energized, relay 13 closes contact 12 across resistor 11, so that if the vehicle moves due to faulty mechanical braking, current from the generator is applied to the motor to limit the vehicle to a low creep speed. The system may be used with a compound wound motor, see Fig. 2 (not shown).

Title: Aperture Card Sensing Method and Means
IPC: G03B21/11
Filed: 1979-02-16
Abstract: A means for determining whether a microfilm aperture card is moving in the direction "X" with its aperture leading or its aperture trailing employs a beam of light (8) from a L.E.D. (7). The beam is projected across the path of the card at a location where it can contact either the film in the aperture or the frame surrounding the aperture. The intensity of light transmitted through the card is detected by a phototransistor 9 which determines whether it is film or frame material which is in the beam. Preferably scattered radiation of between 30 DEG  and 60 DEG  is measured. The card sensing means can be used as part of an automatic card feed to a microfilm reader/printer. (With Figure 1). <IMAGE>
