'Convention date, Jan. 8. [Class 106 (v)] In apparatus for delivering measured quantities of granular and like materials comprising a rotary plate 2 carrying on its underside a number of measuring chambers 3 so that they pass in turn beneath a filling hopper 8 and over a discharge outlet 5 in a stationary plate 4, the rear wall of the hopper is spaced from the top of the plate 2 so that the plate carries a layer of the material from the hopper to a wiper 15 which extends between the hopper and the discharge outlet 5. As the plate rotates the wiper removes the layer of material from above the measuring chambers and deflects it towards a second wiper 16 disposed in the path of the measuring chambers advancing from the outlet 5 to the feed hopper and formed with an arc 16<1> adapted to retain the material until it falls into an advancing measuring chamber. The main filling operation occurs beneath the hopper 8, the levelling off necessary for uniform filling being effected by the wiper 15. The rear wall of the hopper comprises a plate 10 which is adjustable vertically to alter the thickness of the layer of material on the plate 2.

Title: Vehicle Anti-Skid Braking Systems.
Inventor: DAVIS JOHN WALTER
IPC: B60T8/74
Filed: 1965-08-24
Abstract: 1,156,015. Fluid-pressure brakes. DUNLOP CO. Ltd. 11 Aug., 1966 [24 Aug., 1965], No. 36195/65. Heading F2F. A rotary-inertia skid-sensing device for an anti-skid braking system comprises a driving shaft 8 which drives a flywheel 18 through a torque-sensitive coupling consisting of a helical spring 42 arranged within a sleeve 24 secured to the flywheel and extending into a sleeve 21 rotatable independently of both the flywheel and the shaft, the sleeve 21 being coupled to the shaft 8 by a transverse pin 37 passing through openings 38 in a hollow end portion of the shaft which are larger than the diameter of the pin, and the lower end of the sleeve 21 having cam faces 34 engaged with cam faces 33 of an actuating member in the form of a coaxial sleeve 28 which is slidable on splines of the hollow end portion of the shaft 8 so as to rotate with the shaft. A helical tension spring 36 is connected between the second sleeve 28 and the pin 37 such as to act as a torsion spring as well as urging the two sleeves together so that, when the flywheel overruns the shaft as a result of rapid deceleration, relative rotation of the two sleeves is resisted both by the friction between the cam forces 33, 34 caused by the tension in spring 36 and by the torsional force exerted by spring 36. When both these are overcome, the resulting camming action between the faces 33, 34 causes axial movement of the second sleeve 28 which causes it to engage the button 43 of a micro-switch controlling a valve in the fluid circuit of the brakes, or alternatively actuate the valve direct, so as to reduce braking of the associated vehicle wheels. The torsional force exerted by the spring 36 is variable by providing the sleeve 28 with a rotatable end cap 35 to which the adjacent end of the spring is secured, the cap being provided with a flange 44 having a pair of ears 45, 46 which can be bent to engage a series of notches in the sleeve to lock the cap in its adjusted position. The shaft 8 is driven by a gear-wheel 9 engageable with a gear-wheel of the vehicle transmission, the gear-wheel 9 being connected with the shaft 8 so as to provide a predetermined amount of backlash, either by the peg 12 shown which engages a slot in the gear-wheel or by any of the other arrangements described in Specification 1,156,014 which is referred to.

Title: Propulsion system
IPC: B61B13/12
Filed: 1970-07-28
Abstract: 1313788 Vehicle propulsion systems; routing and control systems REX CHAINBELT Inc 28 July 1970 [11 Aug 1969 (2)] 36404/70 Headings B7L and B7N A propulsion system for cars 1 comprises a tube 16 journalled longitudinally in each car and driven by an electric motor 27 via belt 26, the car being propelled by engagement with reaction wheels 30 standing erect from the track which are pivotable about a vertical axis such that the speed of propulsion depends on the angle of attack between the tube and the wheels. The reaction wheels may also be driven. The car is supported on wheels 10 connected with a frame 12 on which the car body and tube 16 are resiliently mounted. The reaction wheels may be disposed directly beneath of or to one side of the tube 16, and may also be arranged in pairs whereby they may guide the cars. The routing of the car is by means of a plate 65 mounted thereon which when the car is loaded is magnetized by means of an encoder 66. Just before reaching a switch a reader will either allow the car to follow the left hand branch as it is conditioned to do, or will energize a rail 42 causing a cam roller 67 to be raised and a cam roller 68 to be lowered whereby the car will follow the right hand branch. To guide the car to the correct branch the cam followers cooperate with cams 72, 81 arranged adjacent the switch. The movement of the cam followers is by a solenoid 45 energized from the rail 42. A rail 41 energizes the motor 27. The speed of a car can be controlled by a signal generator generating a control signal fed to a control device 97. A ram 94, Fig. 12, responsive to the device 97 rotates the wheel 92 for speed control and if it is required to stop a car a hook 99 is actuated by a ram 101 to engage with a lug on the car. Connections 102 between a wheel 92 and preceding wheels 105 &c. may cause the car to slow before reaching wheel 92. Alternatively a control 106 may cause the preceding wheels to stop following cars before they reach wheel 92. A control mechanism, Fig. 13 (not shown), illustrates means by which cars may be run at a fixed speed. Figs. 14 and 15 (not shown) illustrated a method by which cars on a branch track may be incorporated into a stream of cars on a main track.
