Title: Improvements in shock attenuating devices
IPC: F16F13/08
Filed: 1964-05-20
Abstract: 1,040,777. Shock absorbers. G. G. TURNER (W. H. Miner Inc.). May 20, 1964, No. 20913/64. Heading F2S. A shock-absorbing device comprises a resilient annulus 2 made e.g. of rubber having flat, parallel, load-bearing end faces which are bonded to rigid plates 8a, 10 e.g. of metal to form a central chamber 14 which is filled with a flowable damping medium 16 such as asphalt, sand, wax, hydraulic fluid, &c. so that the hysteresis losses of the unit as a whole are enhanced. To facilitate the introduction of the damping medium one of the plates, for instance as shown, the plate 8a is provided with a removable closure 18a protuberances 26, 30, on the closure 18 and the plate 10 respectively, projecting into the chamber 14 in order to guide the flow of damping medium when the annulus is compressed. In a modification, Fig. 5 (not shown), one end of the chamber 14 is closed by a plate 10a which is tapered towards its periphery and is countersunk into part of the upper bearing surface of the annulus. This arrangement lends itself to stacking of several annuli in back-to-back engagement. The plate 8a may be replaced by one similar to the plate 10a and having a removable closure. Modes of stacking annuli are shown. If a plurality of individual chambers 14 is required the intermediate plates 34, Figs. 7, 8 (not shown), can be imperforate or have removable closures fitted therein. A plurality of radiallyspaced chambers may be used instead of the centrally-located single chamber 14.

Title: Automatic frequency control

Filed: 1971-04-19
Abstract: 1343142 Automatic frequency control, frequency comparators MATSUSHITA ELECTRIC INDUSTRIAL CO Ltd 19 April 1971 [13 Feb 1970 (3) 9 March 1970 3 Sept 1970] 21604/71 Heading H3A In an automatic frequency control system, the controlled and reference signals F, S 0  are fed to a frequency comparator which produces a positive or negative a.f.c. pulse signal on one or other of two output terminals depending on whether F > S 0  or F < S 0 , the width of the pulses depending on the frequency difference. In the arrangement of Fig. 1, a sync. signal S 0  and a flyback signal F to be synchronized are shaped by inverters 3, 4, 5 to provide trains of positive going rectangular pulses S<SP>11</SP>, F<SP>1</SP>, Fig. 2, which are fed to NOR gates 8, 9 to produce signal X. The signal S<SP>11</SP> is also inverted at 6 and integrated at 7 to provide a signal S<SP>111</SP>1 which is fed together with the signal X to AND gate 10 which produces an output Y if an S<SP>11</SP> pulse leads an F<SP>1</SP> pulse. The X signal is also fed to gate 13 which inhibits passage of the signal X to output Z whenever an output Y exists. If an F<SP>1</SP> pulse leads an S<SP>11</SP> pulse, no Y output is produced to gate 13 is opened to give a Z output. Phase coincidence of F<SP>1</SP> and S<SP>11</SP> produces no X signal and hence no output occurs on either Y or Z. The lines Y, Z are connected to an integrator, Fig. 3, which provides the control signal and which has a variable time constant controlled by a signal P from Fig. 1. This signal P is applied to a peak detector 17 to provide a switching voltage for diode D 4  which switches R 3 C 3  in or out of circuit depending on the presence or absence of P. Figs. 5, 6 relate to a modification of the discriminator of Figs. 1, 2 which functions in a similar manner, but which employs a different arrangement of gates.

Abstract: 487,923. Current collectors for electric vehicles. ACIERIES DE GENNEVILLIERS. Aug. 9, 1937, No. 21950. Convention date, May 4. [Class 104 (iii)] The collector shoe 1 is mounted to rotate about three axes at right-angles to one another, a vertical axis X-X, a horizontal axis Y-Y, and another horizontal axis through a point O above the shoe.
