Title: Improvements relating to the measurement of fluid flow
Inventor: SCANES PERCY
IPC: G01F1/80
Filed: 1960-09-19
Abstract: 964,731. Measuring fluid flow electrically. GEORGE KENT Ltd. Sept. 8, 1961 [Sept. 19, 1960], No. 32124/60. Heading G1N. [Also in Division F1] The mass rate of flow of a liquid in a-conduit is determined by creating a controlled swirl in the liquid to produce a force on a static sensing member, which is balanced by a centrifugal force whose speed of rotation determines the swirl velocity, and is therefore proportional to the mass rate of flow. As shown, liquid flowing in a duct 1 is deflected by vanes G to create a swirl producing a torque on the axial blades of a rotor R1 which is opposed by a centrifugal force produced by weights 8 on arms 7 rotated by a motor 5, acting through link 10, pad 11 and rod 12 on the rotor spindle. The speed of motor 5 is determined by a differential transformer 16 whose armature 15 is attached to the arms 7. To ensure direct proportionality between the torque on rotor R1, or the speed of motor 5, and the mass rate of liquid flow, the swirl velocity is sensed by a rotor R2 having a number of equispaced magnetic strips 4a on its periphery, producing a pulse train at 4 whose frequency is proportional to the swirl velocity, and is compared at 23 with a pulse frequency difference being used to energize a motor 24 to adjust the angle of the vanes G. Specification 815,645 is referred to.

Title: Traffic control means
IPC: G08G1/096
Filed: 1956-10-22
Abstract: 843,472. Road signals for controlling traffic. JONES, B. Oct. 22, 1956, No. 32134/56. Class 118 (2). A stop and go signal 10 is preceded by a speedindicating signal 11, which may be spaced by a substantial distance such as a quarter of a mile, to indicate to vehicles approximate maximum and minimum speeds between which the vehicle will arrive at the signal 10 during a " go " period. A control box 12 located at any convenient point is connected to the signals by multi-core cables 13 and contains a motordriven drum which carries a series of cams (Fig. 3, not shown) to operate individual switches (Fig. 4, not shown) respectively controlling the lights 14 and 15, and 20 to 25. The lamps 20 to 25 are lit for periods indicated in Fig. 6 by the horizontal lines having corresponding references with the suffix b. These approximate to the hyperbolic curves 40 and 41 which represent the ratio of the distance between the signals 10 and 11 to the time remaining before the termination of go or stop periods respectively, which periods are shown of equal durations of 60 seconds each merely as an example. Speed-indicating signals may also be provided on a cross-road controlled by stop and go lights 16, 17 and these lights may be operated by a second drum mounted on the same shaft as the drum for lights 14, 15 and 20 to 25, or may be operated by a second set of switches cooperating with the same drum but situated 180 degrees from the first set of switches. The system may be applied to a city traffic control system to provide automatic bunching of vehicles which may proceed without interruption at a reasonable speed from block to block, intermeshing with the similarly bunched-flow cross traffic. The usual amber light may be provided in addition to the stop and go lights. In the case where continuous cyclical operation is not desired a secondary cross road may ba provided with vehicle actuated means which starts the drive motor in the control box 12 and an extra cam on the drum ensures that the drive ceases after one complete cycle leaving the drum in a zero (or 120) seconds position (Fig. 6) with a go signal on the main road and wide limits (20-75 m.p.h.) on the speed indicator. A simple relay circuit to obtain such operation is described (Fig. 5, not shown).

Abstract: 1,118,912. Method for forming fibres by splitting thermoplastic film. TOSHIBA MACHINE CO. Ltd. 29 July, 1965 [13 Aug., 1964], No. 32474/65. Heading B5B. Thermoplastic film material is split to form fibres or a fine network structure using a roller having on its periphery a plurality of grooves of equal pitch and cutting edges of equal pitch disposed substantially in spiral form, the speed of the cutting roller being changeable in relation to that of the film in contact therewith, and the angle which the film makes with the cutting roller also being alterable. The cutting roller may be made to rotate in the same direction as the film travelling in contact with it, or in the case of film material which is not easily split, the roller may be rotated in a direction opposite to the direction of movement of the film. By altering the pitch of the grooves and cutting edges of the roller, the speed of the cutting roller in relation to that of the film, and the angle which the roller makes with the film, fibres of varying degrees of fineness may be obtained. A plurality of cutting rollers may be used in an apparatus according to the invention, the thermoplastic film contacting each of the rollers in turn. In one embodiment (Fig. 1) a tap-like cutting roller 3 has a plurality of lands 1 and a plurality of grooves 2, and has a rotational axis 4 so that it can be made to revolve by means of a pulley (not shown) and a belt (not shown). The lands 1 provide the cutting edges and are biased slightly towards the axial direction so that the lands present the formation of a screw thread. A thermoplastic film material 7 moves in conjunction with cutting roller 3.
