Title: Rotary flowmeter
IPC: G01F1/06
Filed: 1964-11-11
Abstract: 1,070,838. Rotary meters. P. HARRISON. Feb. 10, 1966 [Nov.11, 1964], No. 46047/64. Heading F1F. A rotary flowmeter comprises a rotor having two arcuate vane members displaced laterally with respect to the axis of a cylinder from which they are formed to provide a substantially S-shaped fluid path therebetween. The rotor is rotatably mounted in a cylindrical housing to rotate about an axis at right angles to the flow to be measured and means are provided to indicate rotational rate of the rotor. A cylindrical rotor (20) Fig. 2 (not shown) comprising end plates (21), (22) and a central plate (23) includes pairs of laterally disposed semi-circular vane members 30, 31 and 33, 34, Fig. 1, with one pair disposed between one end plate and the central plate and the other pair disposed between the central plate and the other end plate at right angles to the first pair. The rotor is rotatably mounted in a cylindrical housing (10) on bearings (40), (41) to rotate at right angles to the axis of coaxial extension members 15, 16 of the housing through which the fluid to be measured flows. One end plate of the rotor is formed with a plurality of equi-spaced teeth (42) which co-operate with a magnetic pickup (not shown) in a tapped hole (43) to provide an indication of the rotational rate of the rotor and hence flow. The rotational rate of the rotor can be observed through an observation aperture (44). Instead of a magnetic pick-up an optical device could be used to indicate rotor rotational rate. Instead of being divided by the central plate (23) the rotor could be divided into three parts with the outer parts equal in length and half the length of the middle part. The vane members in the outer parts would be in "phase" with each other and the vane members in the central part at 90‹ with respect thereto to minimise the out of balance forces acting on the rotor. The rotor may be made of sheet metal or plastics material.

In a T.D.M. exchange, the subscriber circuits are divided into groups, each group sharing a common speech path and a fault monitoring apparatus associated with a group determines the number of time slots on the path that are in use and isolates the path from the remainder of the exchange if the number is in excess of the number of subscriber circuits. The figure shows a group of 24 subscribers circuits AU1 to AU24 which connect at subscribers lines to the speech path VJ1-VJ2. The exchange includes a plurality of such groups and a common control VC which can selectively connect each group speech path such as VJ1-VJ2 to a common speech path V 1 -V 2  via gates I 1  and I 2 . The monitoring apparatus for the group shown comprises an OR gate O 1  connected to the conductors VJ1 and VJ2 an integration circuit comprising a diode D, capacitor C and resistor R, a gate I 3  closed once per exchange cycle to reset the integrator, a comparator C which receives a reference potential VR 1 F and sets a bi-stable FF if the output of the integrator exceeds the reference and a pair of AND gates A1 and A2 through which the control signals for the gates I 1  and I 2  from the control unit VC pass and which are disabled when the bi-stable is set. The bi-stable is reset at 400 once per exchange cycle. There are 100 time slots on the path VJ1-VJ2 and the reference potential is set to a level that would be produced by the integrator if 50 of these slots were in use. Since there are only 24 subscribers circuits connected to the path this condition can only arise in the event of a fault e.g. in a subscribers line gate. The group arrangement isolating the fault from the remainder of the exchange.

The provision of the restrictor causes a reduction of the delivery at low pump speeds without incurring a corresponding reduction at high pump speeds. Fig. 1 shows a pump of the kind having a slide valve 18 working on the "hydraulic stop" principle, the valve being reciprocable in a cylinder 29 by fuel fed to the latter through a line 27 by an auxiliary pump piston 25 driven in unison with the pumping piston 1. The restrictor 36 may be in the form of a recess parallel to control edge 35 (shown), an annular groove (37), Fig.4 (not shown), or a radial bore (36c) in communication with the edge 35, Fig. 5 (not shown). Rotation of the valve to a position in which a groove 38 aligns with an overflow channel, e.g. for starting, causes maximum delivery to occur, while alignment of a groove 39 with the spill passage 19b stops the associated engine by preventing delivery. Fig. 2 shows an alternative pump in which a spill passage 107, 146 having a restriction 136 in the form of a tapered recess is controlled by an axially displaceable sleeve 118.
