Title: An Improved Suspension Apparatus for Wheeled Axles.
IPC: B60G11/04
Filed: 1918-05-03
Abstract: 130,574. Schneider et Cie. June 15, 1917, [Convention date]. Void [Published under Sect. 91 of the Act]. Field carriages.-Consists in mounting undercarriages of great width, for large guns, on spring- suspended rocking beams connected to axles adapted to be raised or lowered out of or into contact with the ground by screw or hydraulic jack devices acting on the rocking beams. Fig. 2 shows a short axle A carrying two wheels and pivoted about a longitudinal axis E in a bearing carried by a beam B pivoted at its forward end to the chassis and spring-supported at its centre. The beam B has two side-plates carrying a pin B<1> on which is pivoted the lower of two springs D connected together by links d. The upper spring D is secured to a nut F which engages a screw G of a jack device on the chassis so that the chassis may be lowered on to the ground and the wheels raised. Stops B on the plates of the beam B limit the expansion of the springs D. Two side-plates C depending from the chassis guide the beam B. A roller M on an extension C of the chassis limits tilting of the axle A by engaging the wheel-rims. A modification is described in which the lower spring is rigidly secured to the beam B and the jack device connected by a link to the upper spring. In this case the two springs D are separated by blocks. at their ends instead of the links d. Fig. 12 shows a modification in which an hydraulic jack device is used, comprising a cylinder F, piston-rod G, pump P, valve casing N and reservoir Q. Two passages g, g<1> in the piston-rod G communicate with the lower and upper sides of the piston. A rotary valve in the chamber N has passages as shown in the central Passage having a permanent axial connexion to a pipe q leading to the reservoir Q. With the valve in the position shown, operation of the pump raises the chassis off the ground, but, when the valve passages are vertical, the fluid beneath the piston escapes to the reservoir until the chassis rests on the ground, and the wheels may be raised clear by further operation of the pump. Pins f secure the cylinder F in its two extreme positions. Fig. 9 shows a modification in which the forward end of the beam B is pivoted to the jack-device which can also turn about a vertical axis, the upper spring in this case being connected to a spherical head H moving in a curved guide I for steering purposes. A number of these supports may be placed side by side at the rear of the chassis and connected together by transverse rods. A member K on one of the arms B having a pin L adapted to engage notches in a member I<2> enables the arms B to be secured in any position. A two-wheeled forecarriage is used at the front of the vehicle.

Filed: 1964-02-26
Abstract: 1,028,556. Irradiation apparatus. VAKUTRONIK VEB. Feb. 26, 1964, No. 7984/64. Heading H5R. A safety arrangement for indicating damage to a radioactive emitter includes a mechanism, actuated by the foreign body causing the damage, which triggers an electrical alarm circuit. In the measurement of, e.g., the density or thickness of tobacco, the material to be measured is passed in front of a radio-active emitter which could be damaged by foreign bodies from the stream of material, resulting in radioactive contamination of the material. In one embodiment (Fig. 1) the safety arrangement comprises a movable frame 3 carrying a radiation permeable plate 3. If the plate is hit by a foreign body moving towards the emitter 1 from the channel 2 through which the material is passing, the frame 3 is forced to be released from the catch 5, resulting in the compressed spring 6 moving the frame 3 and opening the contacts of an alarm circuit. In a second embodiment a thin non-conductive radiation-permeable plate shields the emitter and has a conductive backing which connects with a pair of contacts in the alarm circuit. If the plate is broken the coating is also destroyed and the alarm triggered. The plate may be renewed after damage.
