Abstract: 1,104,864. Hydraulic brakes. BOFORS A.B. 27 Oct., 1965 [28 Oct., 1964], No. 45523/65. Heading F2F. [Also in Division B7] In steering means for an endless-track vehicle comprising a drive wheel for each track, a brake for each drive wheel, an hydraulic piston for actuating each brake and respective control means providing hydraulic pressure impulses for steering and braking the vehicle, valve means associated with each hydraulic piston and arranged to receive the pressure impulses from the control means transmits to the associated hydraulic piston only the larger of steering and braking impulses supplied simultaneously. In a modification of the steering mechanism described in Specifications 1,078,629 and 1,104,083, fluid pressure is supplied to a single hydraulic cylinder actuating the brake associated with the primary drive to each track through a shuttle valve (Fig. 4) which receives pressure fluid for differential braking and normal braking respectively through pipes 60, 41 and places only that pipe 60, 41 supplying the higher pressure in communication with the brake cylinder through a pipe 59. Chambers 71, 72 at opposite ends of a spool 67 communicate through bores 73, 74 with the pipes 60, 41 so that the spool is displaced by the larger pressure to connect the appropriate pipe 60, 41 with the pipe 59. A servo valve (Fig. 8) supplies fluid to the pipe 60 for normal braking in response to pressure transmitted from a master cylinder actuated by the brake pedal. Pressure fluid from the master cylinder is supplied through a pipe 79 to a piston 94 bearing through a disc member 91 loaded by a spring 93 on a spool 84 loaded by a spring 96. Lands 85, 86, 87 on the spool are normally aligned with chambers 88, 89, 90 in the valve housing 83 such that the pipe 60 communicates with an outlet 64, but when fluid pressure exerted on the piston 94 displaces the spool 84 against the springs 93 96 the pipe 60 is supplied with pressure fluid from an inlet 65. A spring-loaded piston 97 subjected through a passage 101 to the pressure in the pipe 60 opposes the piston 94 to provide " feel ' and a braking pressure proportional to the pedal load.

A mechanism 24 spreads granules over a slotted feed plate 26 to keep the cascade 12 filled and to prevent clumping of the granules. The cascade 12 (Figs. 1-4) comprises a rectangular box having apertures in its sides 80 for the passage of vapour, and containing horizontal baffles 90 having inclined surfaces 92, 94 defining the columns. Electrical resistance heaters 110 are embedded in elements 100 which radiate heat at the exposed upper faces 98 of the zig-zag columns of granules. The heat supply to the various vertical zones of the cascade is controlled in response to temperature readings given by thermocouples applied to the baffle surface 92 and 94, in order to prevent scorching. The granules at the exposed faces 98 are stirred in the upper part of the cascade 12 (to prevent ice crust formation) by angular oscillation of rods 122 carrying U- shaped wires 120 projecting into the faces 98. Each rod 122 is linked at each end by a crank to a strap 126, and the straps 126 are reciprocated by a crank 129a rotated by a motor 129. Each gate 34 comprises a tube 130 slotted at 134 and angularly oscillated to alternately receive dry granules from its associated column and discharge them into the hopper 36. Half the tubes 130 carry sprockets e.g. 137, 138a engaged by a reciprocated chain 140 and the other half of the tubes 130 are driven by meshing gears 144, 145, 146 from the chain-driven tubes 130. The chain 140 is reciprocated by a pneumatic cylinder operated by a cam driven by a motor controlled by an adjustable timer, or manually. On starting, the cascade is initially filled with a filler e.g. dried cracked corn or high density coffee granules. In another embodiment, Fig. 12, heating of the columns is by radiation from hot liquid 210 flowing through ducts 208, 214, 218. The baffles 220, 222 are supported by but thermally insulated from the heated walls 200, 202 by strips 230.
