Abstract: A vibration generator has a driven excitation shaft on which are fixed two axially-spaced first eccentric weights. A second eccentric weight positioned between the two first eccentric weights also rotates with the excitation shaft but is angularly adjustable thereon about the longitudinal axis of the shaft in order to adjust the vibration amplitude. Such adjustment employs a pawl mounted on one of said first eccentric weights for two-and-fro movement tangentially of a gear ring mounted on said second eccentric weight and with the toothed periphery of which the pawl engages. The second eccentric weight is lockable in adjusted position by a friction disc mounted on said one first eccentric weight and into frictional engagement with which the second eccentric weight is urged by a set of annular disc springs disposed in compression between the second eccentric weight and the other of said first eccentric weights.

Abstract: A method and apparatus for terminating the flow of liquid coating material from a jet drop recording device without splattering or seepage is provided. A supply of coating material under pressure is pumped through an inlet valve to a manifold in the printing head of the device. Shutdown is initiated by closing the inlet valve, terminating the supply of coating material. When the pressure in the manifold has dropped to the minimum required for normal operation of the recording device, an outlet valve connecting the manifold to a source of vacuum is opened, rapidly reducing the pressure in the manifold to atmospheric and terminating the flow of coating material from the printing head. A control unit is provided to open and close the valves and monitor the pressure inside the manifold to insure proper sequencing during the shutdown procedure.

Abstract: The invention in question concerns an arrangement on a reception hopper, on a coating machine, for the distribution of a layer of reinforced coating material such as asphalt or concrete. The machine has a centrally located transport unit (11) at the bottom of the hopper (4) designed to transport the coating material in a corresponding direction to the machines longitudinal axis from the hopper to a distribution mechanism. On the respective sides of the transport unit (11), the bottom of the hopper is steered around an axle parallel to the longitudinal axle in order to tip the coating material into said transport unit (11). An innovation with the invention is that the bottom (4) of said respective tippable side parts (1) of the reception hopper features an adjustable rake (5) arranged on an axle (6) which lies adjacent to said tipping axle. The idea behind the rake is to move the coating material from the side parts (1) of the reception hopper to the transport unit (11) via a sweeping movement across at least a part of the circumference of the side parts (1).<IMAGE>
