Abstract: A brake adjuster for the automatic adjustment of vehicle brakes during the brake application stroke has a lever (13) which is connected to a brake cylinder (2) via a piston rod (1) and, via a slack adjuster (15), is connected to a cam shaft (4) with a brake key (5) for brake application. The slack adjuster (15) cooperates via a one-way clutch (20), a torque limiter (43) and a motion transmitter (28) with a control disc (39) which is fixedly connected to a bearing housing (9) for the cam shaft (4).

Abstract: A brake adjuster for the automatic adjustment of vehicle brakes has a lever (13) which is connected to a brake cylinder (2) via a piston rod (1) and which, via a slack adjuster (15), is connected to a cam shaft (4) having a brake key (5) for brake application. The slack adjuster (15) cooperates via a one-way clutch (20) and a motion transmitter (28) with a control disc (39) fixedly attached to a bearing housing (9) for the cam shaft (4). The motion transmitter (28) is formed by a worm wheel (27) which, via said one-way clutch (20), is connected to said slack adjuster (15), and a worm (29) meshing with the worm wheel. The worm (29) is axially movable against the action of a spring (34) upon brake application and is non-rotatably connected to a pinion (31) which is connected to the control disc (39) to transfer the movement thereof, relative to the lever (13 ), to the worm (29).

Abstract: An apparatus for heat treatment of food products, in the form of a product bed consisting of solid particles, includes a container with a perforated bottom for the product bed. Gas is adapted to be supplied to the product bed in the container of this apparatus generally from below upwards through the perforated bottom at such a velocity that the product bed will form a fluidized bed. The gas, which is caused to circulate in the apparatus by means of a fan and to flow through the container as well as through a heat exchanger, is adapted to pulsate through the product bed in the container. According to the invention the apparatus is provided with a conduit passing by the container and being situated before the container with the perforated bottom, as counted in the flow direction, said conduit being provided with a rotatable damper which is adapted during its rotation to raise and lower the pressure under the perforated bottom for the pulsation of the gas through the product bed.
