Title: Improvements in or relating to lubricating systems for internal combustion engines
IPC: F16N7/40
Filed: 1943-09-07
Abstract: 568,003. Lubricating systems. BRISTOL AEROPLANE CO., Ltd., and HANNINGTON, J. D. Sept. 7, 1943, No. 14659. [Class 12 (iii)] In a lubrication system for internal-combustion engines wherein a circulating pump draws oil from a tank to the lubrication points and the oil then drains to a sump whence it is pumped by a larger scavenge pump to the same or another tank, the delivery to the scavenge pump is so regulated that the sump remains' empty when the engine is idling but contains a constant depth of oil when the engine is operating. The regulation is effected by a valve actuated either by a float or by an auxiliary pump. The engine crank-case has a sump .2 containing a scavenge pump 7 of the gear type driven from the engine by a shaft 13 and fed through passage 11 from a valve 9 and passage 10 leading to the bottom of the sump. This valve comprises a member 16 rotated by a float 15 and housed within a sleeve 17, members 16, 17 having ports 20, 21 leading to passage 11. The valve is by-passed by an opening 22 in the pump casing 12 which leads through a calibrated orifice 23 to the passage 11, the delivery through this by-pass being 'less than the capacity of pump 7 so that the sump is kept dry during idling periods. At other times, oil collects in a cup 27 and actuates the float 15 to rotate member 16 and permit the oil to pass through valve 9 to the pump. Should the float be punctured, the cup 27 supports it in the lowest position that keeps the valve open. The orifices 22, 23 may be replaced by additional ports in the valve. In a modification, an auxiliary pump is connected to a valve sliding against the action of a spring to bring the main ports into action.

Title: Improvements in and relating to the operation of self-excited d.c. generators
IPC: H02P9/12
Filed: 1945-06-13
Abstract: 593,627. Electricity supply; exciting dynamo electric machines. ENGLISH ELECTRIC CO., Ltd., and SHAW, N. H. June 13, 1945, No. 14993. [Classes 35 and 38 (iv)] An auxiliary source of D.C. power is tem-À porarily inserted in series or parallel with the field circuit of a self-excited D.C. generator to assist build-up of its output voltage after a momentary overload. As shown, the generator 1, 1a is an exciter for an alternator 2, 2a, the generator field 1a normally being controlled by the alternator volts through an automatic regulator 4. A battery 6 is automatically connected in series with the field 1a under conditions of low generator and alternator volts by a contactor 7 and remains so connected until the generator volts become excessive. The contactor is controlled by relays 8, 9, contacts 4a which close when the regulator 4 is in the all-out position (viz. when the alternator volts are low) and contacts 3a which are closed so long as the circuit breaker 3 of the alternator is closed. Relay 8 has contacts 8a which close in response to low generator volts and, if the alternator volts are also low, the contactor is energized over contacts 3a, 4a, 8a to insert the battery in the field circuit. Rectifier 5 prevents discharge of the battery through the regulator. Upon build-up of the generator volts to an excessive value, normally closed contacts 9a of over-voltage relay 9 open a byepass around the now open contacts 8a and allow contactor 7 to drop out and disconnect the battery. In a modified arrangement, relays 8, 9 may be omitted and the battery connections controlled by regulator 4. The battery may be connected by contactor 7 across a field discharge resistance in series with field 1a, the contactor having further contacts which shortcircuit the resistance when the battery is out of circuit. Specification 528,789 is referred to.
