Abstract: 1,117,597. Jig washers. VERSCHURE & CO'S SCHEEPSWERF EN MACHINEFABRIEK N.V. 26 July, 1965 (4 Aug., 1964], No. 31873/65. Heading B2H. In an apparatus for separating ore from a mixture of sand, ore and water and comprising a number of successively disposed tanks 1-4, Fig. 2 (not shown), containing water, with a gravel bed 6 at the top of each tank and a pulsator 7 for pulsation of the water, a horizontal boundary wall 8 having a certain freedom of movement in the vertical direction is provided at some distance above the gravel bed. As shown, the boundary wall 8 is constituted by a plank, floating on the mixture and secured to the top edge of the tank by means of a rubber diaphragm 9 or by diaphragm-like strips. Alternatively, the boundary wall may consist of a diaphragm whose edges are connected all round to the tank. In operation, the mixture is fed at 5 to the first tank and flows over the gravel bed, the pulsations being transmitted to the mixture causing heavier ore particles to be separated from the sand and to sink to the bottom of the tank through the gravel bed. The sand particles with the water and unseparated ore particles pass on to the following tanks where further separation takes place. The boundary wall 8 ensures that the thickness of the layer of mixture is kept constant for efficient separation and is especially useful when the apparatus is used on board of a ship in motion.

Title: Improvements in or relating to vehicle couplings or hitches
Inventor: HAMBLIN LESLIE FRANK
IPC: B62D53/06
Filed: 1954-11-06
Abstract: 775,554. Steering trailer vehicles. SENTINEL (SHREWSBURY), Ltd., and HAMBLIN, L. F. Oct. 28, 1955 [Nov. 6, 1954], No. 32186/54. Classes 79(3) and 79(5). In a tractor-trailer combination 10, 11, incorporating a weighttransferring coupling, means are provided for controlling the steering movements of the front axle 24 of the trailer 11 in accordance with the weight transferred from the axle 24 to the tractor 10. As applied to a trailer in the form of an earth scraper having a goose neck 17 supporting a kingpin 18 for swivelling movement of a pair of forward wheels, an assembly 14 rigid with the kingpin 16 is connected by a link 12 to a fitting 13 on the tractor 10. A hydraulic ram 15 is in connection between another point on the assembly 14 and the fitting 13, so that when hydraulic pressure is applied to contract the ram 15, wheel-loading is progressively transferred from the wheels x to the driving wheels y of the tractor. The kingpin 16 carries a cam 18, on which bears the plunger of a hydraulic ram 19 which is pressurized with the same fluid as the ram 15. Resistance to turning of the wheels x is thus increased in proportion to the decrease in the loading which they bear. In the modified construction shown in Fig. 3, an assembly 26, cam 27, hydraulic ram 30, and goose neck 20, are substantially the same respectively, as the assembly 14, cam 18, ram 19, and goose neck 17, of the construction of Fig. 1. The link 12 is replaced by a tow-bar 40 universally connected to the tractor at 41 and rigid with side plates 42 secured to the assembly 26. A shaft 44 journalled in bearings carried by the assembly 26, is keyed to an arm 45 connected by a hydraulic ram 46 to an intermediate point of the tow-bar 40. A pair of arms 49 each rigid with the shaft 44, bear on respective sides of the axle of the wheels x, which is pivoted at its central point on a pivot pin 25 carried by the foot of the kingpin 21. When pressure is applied to the ram 46, weight is again transferred from the wheels x to the wheels y of the tractor. Pressure is also applied to the jack 30 so that a roller 36 carried by its plunger 32, bears on the cam 27. The roller 36 engages a central lobe formed in the profile of the cam corresponding to the straight ahead position of the wheels x. The plunger 32 and roller 36 are guided by means of rollers 35, 35, which bear in a track 29. The cam 27, or a separate cam associated with the assembly 26, may be arranged to control a release valve in the hydraulic circuit of the ram 46. Thus the amount of weight transference possible is automatically reduced with deflection of the wheels x. The axle of the wheels x may be arranged so as to trail with respect to the kingpin. Specification 775,553 [Group XXXII] is referred to.
