Title: Single Axis Accelerometer.
Inventor: ROGALL HERBERT
IPC: G01P15/13
Filed: 1967-07-04
Abstract: 1,161,143. Measuring acceleration electrically. SINGER-GENERAL PRECISION Inc. July 4, 1967 [Oct. 3, 1966], No.30787/67. Heading G1N. In an accelerometer in which the movement of a pendulum 12, Fig. 1, under acceleration is detected electrically and an equivalent restoring force is applied to the pendulum, the housing 38 acts as the return path for flux from magnets 14, 16 which, together with coils 50, 52 carried by the pendulum, form the restoring force generator. The housing also includes material in which eddy currents are induced for damping the movement of the pendulum. The pendulum is attached to the housing by a pair of flexures (40), 42, see also Fig .2 (not shown), which permit it to move in a direction perpendicular to their plane. The movement of the pendulum may be sensed using an inductive displacement transducer having primary coils 20, 22, see also Fig.6, attached to polepieces 30 of the magnets 14, 16 and a secondary coil 18 carried by the pendulum. Alternatively, employing eddy current techniques, primary coils (180, 182, Figs.5, 8 not shown), and secondary coils (184), (186), carried by the two polepieces 30, are inductively connected by the pendulum (188). In a third embodiment, the pendulum (106, Figs.4, 7 not shown), forms one plate of a differential capacitor, the other plates of which are formed by the polepieces (108), (110) of magnets (116), (118). In each case the output of the transducer is fed to an amplifier 90, Fig. 6, whose output is supplied to the restoring force generating coils 50, 52 and a resistor 102 across which a meter 96 is connected which gives an indication of the acceleration.

Filed: 1960-09-07
Abstract: 966,967. Gas - filled cigarette lighters. NATIONALE S.A., and RONSON CORPORATION. Sept. 7, 1960 [Sept. 8, 1959], No. 30875/60. Heading F4F. [Also in Division F2] When the nozzle 18 of a refill container of liquefied gas is inserted into a lighter filling valve (Figs. 1, 2), comprising a fixed housing 2, a resilient sealing member 15 and a member 7 movable against spring pressure, movement of the sealing member 15 away from a rib 6 on the housing 2 opens communication between an exhaust passage 17 and atmosphere through an annular space surrounding the nozzle 18, and movement of a shoulder 9 on the movable member 7 away from the sealing member 15 opens communication between inlet passages 13 and the interior of the lighter reservoir whereupon liquefied gas can flow from the refill container to the reservoir through a hollow needle 12 which penetrates a resilient lozenge 19 sealing the nozzle 18. In another embodiment (Fig. 3), the movable member of the valve consists of a rubber membrane 23 which the nozzle tip displaces from contact with the sealing member 15 to open communication between a bore 26 in the nozzle and the interior of the reservoir through ports 24 in the membrane and recesses 27 in the nozzle tip. A shoulder 28 on the nozzle displaces the sealing member 15 from the rib 6. In another similar arrangement (Fig. 7, not shown), a spring- loaded movable member replaces the membrane 23. In a further modification (Fig. 8), the tip of the nozzle 18 moves a sealing membrane 38 from the inner edge of a groove 40 in the movable member 36 to open communication between the nozzle and inlet ports 39, and a shoulder 29 on the nozzle depresses the movable member 36 so that the outer edge of the groove 40 displaces the sealing membrane 38 from the rib 6. In yet another arrangement (Figs. 5 and 6, (not shown), the sealing member consists of a rubber ring which is located in an annular groove in the fixed housing for co-operation with the movable member and the nozzle of the refill container.

Filed: 1975-07-25
Abstract: 1501520 Test tape INTERNATIONAL BUSINESS MACHINES CORP 25 July 1975 [6 Aug 1974] 31162/75 Heading G5R A test tape 10 for helical scan tape recorders carries servo tracks 11, 12, identification track 13 and a plurality of helically recorded test track sections including sections A-C each carrying recorded signals for testing various aspects of the recorder during playback. Test section A is provided at the beginning, middle and end of the tape for checking the tracking operation of the recorder and comprises a series of helical tracks, e.g. 50, such that the spacing between tracks increases, e.g. 2% between adjacent tracks, from normal to a distance equal to the track width. Each track is similarly recorded with a series of groups of 8 bit bytes and the played back signal is supplied to a computer which provides a print out indicating the number of bytes in error in each group. The error pattern indicates whether the playback transducer path is in alignment or skewed, whether the tape is correctly wrapped and provides an indication of cross-talk between tracks. Test section B comprises a plurality of helical tracks recorded with a high frequency square wave signal with approximately 100 erase tracks made through the section extending longitudinally of the tape. The envelope of the played back signal is generally of triangular shape and by counting the number of high frequency signal transitions between signal pick-up and drop out several parameters, e.g. skew of read gap, track profile (tape path around guide mandrel)and held profile (feed-tape spacing around the mandrel) can be determined. Test section C consists of a series of e.g. 100 helical tracks each recorded with groups of 32 byte square wave signals with one square wave signal in each byte being reduced, e.g. 1% per track, in duration. A computer read-out of byte errors provides an indication of sensitivity and cut-off of the read back circuits of the recorder.

Title: Improvements in or relating to hydraulic shock absorbers
IPC: B60G15/06
Filed: 1922-11-17
Abstract: 191,006. Lancia & Co. Dec. 28, 1921, [Convention date]. Fluid-friction vibration-dampers.-An hydraulic shock-absorber for vehicle suspensions and other purposes consists of a hollow member constituting two cylindrical chambers which are separated by a fixed partition and in one of which a valve plunger is slidably mounted with its stem passing through an aperture in the partition. A space is formed between the plunger and the partition, and communicates with the two chambers through passages having a minimum section when the capacity of the space decreases; the plunger stem is also provided with a duct communicating with the spaces and with the two chambers. The invention is shown applied to the resilient mounting of wheels 3, the pivots 2 of which are resiliently connected to the frame 1, a coil spring 6 bearing on the pivot and on a cap 7 in the frame. In the frame slides a hollow stem 5 locked within the pivot 2, its lower end sliding in a cylinder 8 on the frame. Through a partition 5<1> in the stem slides a hollow stem 12 solid with a plunger 11 and with a hollow stem 13 connected to the cylinder 8. The duct 12<1> in the stem 12 connects by ports 18, 19 to the spaces 10, 14 below and above the plunger, while the duct 13<1> leads from a cap 21 to the chamber 10 through a port 20. Cap 21 is removed when filling the apparatus with oil through plug 22. Ports 15 in the plunger are normally closed by a spring-pressed valve 16, but on upward movement of the wheel the valves open to allow fluid to pass from chamber 14 to chamber 10, the area of the ports restricting the flow. On the return stroke the valve closes and increased damping results from the restriction of the outflow port 19. The chamber 10 is closed at the bottom by a sliding disc 10<1>. and leakages from the chamber 10 lubricate the contact surfaces of the stem 5 and cylinder 8.
