Title: Flow meter
Inventor: SORENSON PERC CHARLES
IPC: G01F1/24
Filed: 1961-11-16
Abstract: 1,011,855. Flow and miles per gallon metres. P. C. SORENSON. Nov. 16, 1961, No. 41069/61. Heading G1N. The Specification describes and claims a meter in which a resistor is varied in accordance with fuel flow for use in conjunction with a device producing a voltage representative of engine speed in order to give an indication of miles per gallon. The voltage producing device may be a small generator connected between the transmission power takeoff and the flexible drive cable to the speedometer or between the drive cable and the speedometer. Flow meter construction. A float 86, raised by fuel flow against gravity, carries a varying depth slot 88 and moves in a slotted tube 82 so that a portion of the varying slot co-operates with the fluid slot to an extent determined by the flow. Attached to a rod 110 depending from the float is a permanent magnet 112 (Fig. 6). This travels along one side of a central partition dividing a chamber 102 into two compartments. In the other compartment are two resistance strips 94 which are connected together at various positions by a permanent magnet 96 which moves up and down with magnet 112 on the other side of the partition. Magnet 96 is round so that it rolls on the resistor; it may also be copper-plated. Instead of a tapered slot in the float a tapered bore may be provided in tube 82 (Fig. 5, not shown). In a further embodiment (Figs. 16 to 24, not shown) the permanent magnet carried by the float is mounted in a cage and provided with stub axles which allow it to rotate as it moves up and down. The electrical resistance on the other side of the partition is in the form of a printed circuit element on which one side of the roller moves and a wound resistor over which the other moves. The first few turns of the resistor are short circuited to avoid errors caused by the fixed resistance of the generators &c. Modifications. A voltage proportional to vehicle or engine speed is not necessary. In the arrangement described with reference to Figs. 11 to 13 (Fig. 13 only shown), a voltage source 126 is provided to give an output equal to that of the above-described generator when the vehicle is driven at a certain speed. In use, with a switch 144 in the position shown, a potentiometer 132 is adjusted until a desired speed is indicated on one scale of a meter 148. Switch 144 is then changed to its other position and the vehicle driven at the desired speed when the instrument shows miles per gallon on its other scale. In a further arrangement (Fig. 14, not shown) the generator is driven from a wheel drawn behind the vehicle under test and in the arrangement of Fig. 25 (not shown) the generator output is fed through 9 smoothing circuit.

Abstract: 984,367. Load cells. BERLINER INDUSTRIEWAAGENFABRIK G.m.b.H. Nov. 17, 1961, No. 41296/61. Heading G1N. Fig. 1 shows a strain gauge in the form of a body of revolution consisting of a central circular plate 1 to a recess 8 in the upper surface of which the load is applied. Reduced portions 2 support the device and extensions 5, 6, carry strainable windings, one of which is in compression and the other in tension. The arrangement is that the inward movement of the support ring caused by the centre of the device sagging under load is offset by its outward extension resulting from its location below the neutral line. In consequence, no relative movement of the annular supporting ring 2 and its support takes place. Fig. 2 shows an alternative construction in which the load is applied via a pot-shaped extension 11 and the device is supported on a cylindrical extension 9. In Fig. 3 (not shown), the load is applied through a ring- shaped member attached to the centre of the device and in Fig. 4 (also not shown) a lower extension serves to support both the device as a whole and the lower strain gauge.

Abstract: 1428786 Transistor switching circuits HONEYWELL INFORMATION SYSTEMS Inc 5 Sept 1973 [20 Oct 1972] 41851/73 Heading H3T To speed the current build-up in alternately energized coils 10 (12, Fig. 1, not shown) the current switching circuit T88, T94 for each coil has a part T94 shunted by a lower impedance path T108 for a limited period determined for example by a monostable 40. When the binary input at 14 is low, inverter 16 turns on T74, T94 to energize coil 10. The initial change to the low input also turns off T64 for a time dependent upon C66 so as to trigger the monostable 40. This enables AND gate 28 to pass the high level from inverter 16 to T108 base thereby shunting T94 and R96 for the monostable period. A change to high input turns off coil 10, and this time circuit 20 triggers the monostable 40 so as to pass the high output of inverter 18 through AND 38 to turn on the shunt circuit in 120 (46, Fig. 1, not shown) which is identical to 42. Transistors identically arranged to T88, T94 are also operated in 120. Diodes 90, 95 protect from reverse voltages in the coils 10 (12). The coils both operate on the same solenoid armature.
