Patent GB-689496-A (GB)
Abstract: 689,496. Registering time of running of machines. NALLINGER, F. June 29, 1950 [June 29, 1949], No. 16328/50. Class 106 (iv). A meter for registering the time of operation of an internal combustion engine comprises means for using a pneumatic, hydraulic or electromagnetic force which is brought into action by the engine during its operation for winding up a clockwork for driving the meter and also for setting the clockwork in and out of action. In one embodiment, Fig. 1, a diaphragm capsule 3 communicates through a passage 5 with the suction pipe of the engine and the diaphragm 4 is connected to a lever 6 for actuating a brake 8 through a link 7 and the winding means of clockwork through a rod 9. The brake 8 may act upon a pallet 11 coacting with a wheel 10 of an escapement subject to the action of a spring 12. A rack 13 coupled to the rod 9 by springs 14, 15 drives a gear-wheel 16, one way or the other, with to and fro movement of the rod 9 and the wheel 16 drives the winding-shaft stressing the spring for the wheel 10 through a free-wheel device 17 or other locking device acting in one direction of rotation. The clockwork may be driven by means of a pawl-andratchet mechanism 20, 21 driven by worm gearing 18 and a crank 19 which in turn drives the meter wheels through necessary transmissions which may include intermittentlyacting pairs of cam or toothed wheels 22, 23. If the spring of the clockwork is fully wound when the engine is set in operation, movement of the rod 9 will merely compress the spring 15 without moving the rack 13 so that overstressing is prevented. In another embodiment, Fig. 2, when the engine starts, current, which is available only when the engine is running, passes through coils 26, 31 displacing to the left armatures 27, 32. The former actuates a braking lever 8 to set the clockworkdriven indicator in motion while the latter tends to move a lever 33 to the left against the spring of the clockwork, and as it moves keeps the clockwork fully wound. If the engine runs long enough the armature 32 moves a toggle device 40, 41, 42 over its dead centre position and actuates a switch 30 to open the circuit through coil 31 whereupon the spring 44 returns the armature 32 to its right hand end position. Clockwise movement of the lever 33 is permitted by a free-wheel device 35 while the clockwork spring is maintained stressed by a locking device. The release and arrest of the meter and the winding of the meter may be effected by the same device such as a diaphragm, piston or electromagnet or by two different devices.
Patent GB-774803-A (GB)
Abstract: 774,803. Electrical measuring systems. PHILIPS ELECTRICAL INDUSTRIES, Ltd. June 16, 1954 [June 17, 1953], No. 17687/54. Class 40 (1). In a device for measuring the extent of comparatively rapid variations of a physical value, e.g. strain, from a constant or slowly changing average value, when the sum of all periods in which the value corresponds to the average is larger than that of periods when it is not, and in which a voltage derived from the value and a second voltage dependent on the position of a member 5 are fed in opposition to an amplifier 6 the output of which drives a motor 7 displacing said member, the second voltage is derived from a bridge circuit 3, one branch of which contains a high temperature coefficient resistor 8 in thermal contact with a heating element 10 which is heated as soon as the member moves from its rest position in one direction so that any slow variations in the first voltage have no long term effect on the position of the member. The outputs of bridge 1 consisting of strain gauges subject to the force and compensating strain gauges and of bridge 3 are applied in opposition via amplifier 6 to motor 7 which moves the sliding contact 5 to restore the difference voltage to zero. The arms of bridge 1 may be subject to temperature conditions varying with time so that the bridge output corresponding to zero strain varies. To prevent this from affecting the position of sliders corresponding to zero strain the high temperature coefficient resistor 8 which is heated by incandescent lamp 10 whenever switch 10 operated in response to movement of contact 5 is closed. Whenever bridge 1 is unbalanced in such a direction that the contact is driven to the right, the heater circuit is closed, so causing the resistance of negative temperature coefficient resistor 8 to fall, and the contact to be driven back to its zero position whereupon the circuit is opened and the contact again moves to the right. The contact 5 under such conditions oscillates, but the circuit constants are such that it deviates little from its zero position. The lamp 10 is mounted in a recess in a block of e.g. aluminium comprising a channel in which the insulated resistor is fixed. This gives a unit with high thermal inertia so that strains of short duration occurring relatively infrequently produce a response of the system as if the unit were absent.
