Title: Improvements in or relating to load or shock absorbing devices
IPC: B60G11/27
Filed: 1938-08-12
Abstract: 520,222. Shock-absorbers. FIRESTONE TYRE & RUBBER CO., Ltd. Aug. 12, 1938, No. 30770/39. Convention date, Sept. 17, 1937. Divided out of 517,986. [Classes 108 (ii) and 108 (iii)] A shock absorber includes a compressible container and an air reservoir, with a valve allowing free flow from the container to the reservoir, with restricted flow in the opposite direction, and means, normally in the path of the valve member but moving out of said path under the influence of acceleration, said valve member having a rubber seating surface. As shown in Fig. 2 a pendulum 163 having a disclike rubber bumper 166 and a valve-engaging extension 168 is suspended in a casing 161 threaded into a dome-shaped cover 86 mounted on the bellows casing 75, a pipe 93 leading from the cover to the reservoir. Upper and lower rounded valve seats 171, 170 defining a chamber 172 are formed in a cap 162 closing the lower end of the casing and are adapted to be engaged by a rubber-faced disc-valve 173 carried by a stem 175 slidable in a guide 177 supported by webs 178 on the cap 162. Normally the valve is prevented from engaging the upper valve seat 171 by the pendulum-extension 168. Bye-pass apertures 179 in the cap 162 connect the chamber 172 and the interior of the bellows. Inside the casing 161 recesses 181 spaced 90 degrees apart are formed into which the pendulum may swing when the vehicle is braked or rounding a curve, the valve 173 then being free to rise and engage the upper valve seat 171 shutting off the reservoir from the bellows. In a modification the valve seats are flat and the rubber facing on the valve is formed with a beaded periphery. Fig. 6 shows a construction on which a reinforced rubber flap valve 197, integral with a gasket 198, is movable between valve seats 195, 196 and has an extension 202 normally engaging the pendulum extension 193 and formed with flat faces 202a, Fig. 7, past which the pendulum extension must swing before the valve can hinge upwardly. Bye-pass. openings 203 formed in the cap 191 closing the end of the pendulum casing 190 permit slow passage of air into the bellows when the valve engages the lower seat 196. In a modification, a valve similar to that shown in Fig. 6 is mounted in the reservoir inside a casing formed with a large number of radial apertures to subdue noises arising from the operation of the valve. In a further construction, Fig. 9, in order to prevent excessive transfer of air from the bellows when the vehicle strikes a large bump, an additional weighted flap-valve 224 is provided below the flap-valve 197 in a chamber 222 and normally is supported by lugs 226, extending inwardly from a cap 216 closing the lower end of the casing 213. In operation, on sudden compression of the bellows and downward movement of the casing structure, the inertia of the flap-valve 224 causes the valve to engage the valve-seat 223 so that air from the bellows can only escape through restricted bye-pass openings 220 and then past the flap-valve 197.

Filed: 1964-05-20
Abstract: 1,073,964. Electromechanical oscillators and filters. SIEMENS A.G. May 20, 1964, No. 31573/66. Divided out of 1,073,962. Heading H3U. A mechanical resonator oscillating in the bending mode carries two piezoelectrio crystals having their planes perpendicular to the longitudinal axis of the resonator, being located predominantly in a region bounded by two adjacent nodes of oscillation, one crystal on each side of the neutral axis of the oscillator, and being mutually oppositely polarized, the crystals being arranged to divide the resonator into two distinct parts. In Fig. 1, steel bars 1, 2 are united by two crystals 3, 4 which are soldered to the bars via layers of silver used for applying the polarizing voltages. A gap S prevents parasitic oscillations and permits the directions of polarization to be opposite. Further resonators can be attached at the nodes 7, 8 to provide a multistage filter. A quadripole element can be obtained by including a second pair of crystals in a further gap in the bar (Fig. 3, not shown). This pair may or may not be of the same thickness as the first pair. The phase of the output then depends on the relative directions of polarization of the two pairs of crystals. Alternatively, the crystals can be divided by a conducting layer in a plane at right angles to the axis of the bar (Fig. 4, not shown). In another form of construction (Fig. 8, not shown) pairs of crystals are included in one or both arms of a tuning fork. These crystals may be divided by a conducting, layer as in Fig. 4. The resonating member may be of quartz instead of steel and may be of circular instead of rectangular cross-section. Harmonic suppression using the arrangement of the invention is described in Specification 1,073,962.
