IPC: F16H61/04
Abstract: 1,050,976. Change-speed control; brakes. DAVID BROWN TRACTORS Ltd. Sept. 7. 1964 [Sept. 7, 1963; June 11, 1964], Nos. 35412/63 and 24220/64. Headings F2D and F2E. A tractor transmission comprises a power take-off shaft 12 mounted within a hollow input shaft 10 passing through the casing 22 of a non - synchronized change - speed gear and coupled to a hollow clutch shaft 11, the shaft 10 carrying a centrifugal friction brake which is automatically held released when the shaft rotates within its normal operating speed range and is engaged when the drive is disconnected and the speed drops preparatory to making a gear change. As shown in Fig. 1 the brake consists of a pair of longitudinal arms 15 pivoted at 17 to a carrier 16 and provided with arcuate shoes 20 which are urged against the casing 22 by springs 23 when the shaft 10 is stationary, the springs being overcome by centrifugal weights 19 to release the shoes when the shaft rotates at normal speed. In the arrangement according to Fig. 3 brake shoes 37 carried by pivoted curved arms 36 are engaged with a drum 45, secured to the gear casing, by tension springs 43 when the shaft 10 is stationary, the spring loading being overcome by the centrifugal effect of arms 36 to release the brake when the shaft rotates.

Abstract: 1,051,209. Rotary meters. ROLLS-ROYCE Ltd. July 29, 1965. No. 32567/65. Heading F1F. A rotary meter for measuring the rate of fluid flow through a conduct 3, Fig. 3, comprising a rotor hub 5 formed with a plurality of blades (not shown) rotatable by the fluid is carried by a shaft 6 which through a magnetic coupling 13, 14 rotates a shaft 12 carrying a disc 16 with a plurality of holes 17, therethrough. The disc 16 is interposed between a photo-electric cell 27 and a mirror 21 reflecting light from light sources 23 located in "in-line" relationship with the bores in tubular struts 4 concentrically supporting a body member 9 in which the shaft 12 is bearingly mounted. The body member 9 is sealed against inflow of fluid by a non-magnetic non-conducting inflexible diaphragm 15 interposed between the magnetic coupling parts. As the rotor hub 5 together with its blades and the shafts 6 and 12 rotate the light from the sources 23 reflected by the mirror 21 is interrupted by the metal between the holes 17, so that pulses of light falling upon the photo-electric cell 27 are transformed into corresponding electric pulses which are sent to a calibrated counter to determine the flow rate of the fluid. The mirror may be omitted and the blades made of light reflecting material to reflect light from the light source on to the photo-electric cell. The mirror 21 and the member 19 on which it is mounted may rotate with the shaft 12 in which case the disc 16 can be dispensed with.

Abstract: 1,226,204. Shaft encoders. AUTOMATION DEVICES Ltd. 13 May, 1969 [13 May, 1968], No. 22554/68. Heading G4H. An incremental shaft encoder, e.g. for a fuel pump at a service station comprises a toothed wheel and a detector having an E-shaped ferromagnetic core carrying a pair of windings 24, 25 forming part of an oscillator adapted to oscillate when the bridge is unbalanced, the passage of a tooth past the core causing unbalance, and means responsive to a burst of oscillation to produce an output pulse. The windings 24 and 25 are connected in a bridge with resistors 26 and 27, a potentiometer 28 serving to provide an adjustment. The signal on the slider 29 via capacitor 30 passes to an amplifier consisting of transistors 31 and 35. Feed-back via resistor 39 stabilizes the operation of the transistors against changes in the supply voltage. The output from the collector of transistor 35 are connected via capacitor 40 to the primary winding 41 of transformer 42. This winding is tuned to oscillate at a frequency of 20 kHz, the secondary winding 44 is connected across the bridge. If the bridge is balanced the losses are sufficient to prevent the system oscillating. When a tooth 55 moves to a position as shown where it affects one side only of the core, the bridge is unbalanced and the system oscillates. The oscillations are taken via capacitor 47 to rectifying diodes 48, 49 to give a D.C. pulse at 54. The output pulses are received by an indicator giving a numerical display. To avoid the generation of spurious signals when a tooth stops in a critical position a feed-back is taken from the diode 49 via transistor 56 and variable resistor 58 to the junction of resistors 32 and 33 in the emitter circuit of transistor 31. This produces a backlash effect which prevents spurious outputs. The tooth members 55 may be ferrite inserts in a brass disc or may be separate radial teeth of ferromagnetic material. The time constant of the rectifier circuit may be such that no output pulse is developed until a proportion of the total number of the oscillator pulses is received by it. The pump may be controlled by the output pulses to deliver a predetermined quantity, the pump slowing down at a first value and stopping at the predetermined value.

In the preferred embodiment, the space A is partly filled with oil, or a liquid with similar characteristics and communicates through a restricted orifice 35 and a passageway 32 with an oil filled chamber E. A space 19 and chambers B communicate with each other and through a passageway 50 with an inlet connection 8 to a sprinkler system.
