Abstract: 1,176,791. Vibration damping unit. DELANEY GALLAY Ltd. 4 Jan., 1967 [6 Oct., 1965], No. 42478/65. Heading F2S. A vibration shock-isolation, or absorption, unit, e.g. for use as a vehicle or engine suspension unit, comprises at least a pair of cylindrical pads of matted fine springy metal wire which is woven, knitted, or compressed into a tubular resilient mass mounted on a former concentrically about a common axis and arranged so that one of the pads is preloaded in compression and the other is unloaded in the free standing condition of the unit or, at a lower unit compressive loading than the first-mentioned pad. Three cylindrical wire mesh pads 2 and a single wire mesh pad 2<SP>1</SP>, all formed as described in Specifications 711,898 and 715,796, are mounted in a precompressed state, on a central tube 4 between end plates 6, 6. The unit is adapted to resist stresses in both upward and downward directions. The tube 4 acts as one loading connection the other consisting of the flange 8 of a sleeve 10 which has an inwardly directed part 12 located between the uppermost pad 2 and the single pad 2<SP>1</SP> with the corresponding flange of a cylindrical member 20. Stiffer limiter metal wire mesh pads 14, 18 are located respectively concentrically around the pads 2, 2<SP>1</SP> between an end plate 6, and the corresponding flange 8, or cylindrical member 20. When the unit is loaded the static load is taken up by the difference in load bearing capacity between the pads 2 and the pad 2<SP>1</SP> so that the deflection curve is symmetrical about the load point, the curve having a soft ride characteristic over the straight characteristic portion and a smooth transition into the progressively increasing stiffer portions due to the concentric limiter pads 14, 18. In a modification, Fig. 3 (not shown), which is generally similar to that shown in Fig. 1, there are three upper pads (2<SP>1</SP>) which are made of finer metal wire mesh than a single lower pad (2) which is stiffer. The intermediate connection comprises a sleeve (28) and an upper concentric limiter comprises a pad 38, a coil spring (32) being located between the lower end plate (6) and the sleeve (28). The load-deflection curve is substantially the same as the first embodiment. In a further modification, Fig. 4 (not shown), a shorter pad (2<SP>1</SP>) is concentrically located around an outer pad (2), no limiters being provided in this case.

Title: Video disc recording playback and sync storage locations
IPC: G11B7/004
Filed: 1975-10-21
Abstract: 1526440 Video disc apparatus RCA CORPORATION 21 Oct 1975 [12 Nov 1974] 43218/75 Heading H4F [Also in Division G5] A video signal is recorded as a succession of depressed and non-depressed regions in a spiral track on a disc 70 in such a manner that corresponding horizontal sync. signal locations in successive convolutions of the track are not radially aligned but form spiral loci transverse to the track spiral, the disc being rotated at a constant angular rate during playback. The disc may be of optical type, or of the variable capacitance type disclosed in Specification No. 1,417,708. The recording in each convolution of the spiral may correspond to 2097À9 horizontal line intervals, i.e. 2À1 line intervals less than eight full field intervals for a 525 line system. Recording apparatus for such a disc comprises modulator 12, 22 to frequency modulate respective carriers with video and audio signals respectively, a duty cycle modulator 24 in which the output of modulator 12 is duty cycle modulated by the output of modulator 22 in the manner described in Specification No. 1,460,911, and an electron beam recorder 30 including a scanning electron microscope 31 giving an electron beam intensity modulated by the output of modulator 24. A master disc 70 is rotated with a tacho disc 36 by a drive 34 at a rotational rate f R  which differs from an integral submultiple of the field rate of the video signals by a fixed small amount, e.g. f R  = 7À5 rps for video signals at the U.S. colour broadcast standard field rate of 59À94 fields/sec. Drive 34, which may be of the fluid propulsion form shown in Specification No. 1,420,322, is controlled by a servo circuit in which the output of a tacho pickup 40 is compared with a reference oscillator 60. The recorder may be used to record in a slower-than-real-time mode by rotating the disc 70 at a rate corresponding to a fraction (e.g.<SP> 1</SP>/ 21 ) of the intended playback rate and dividing the recording signal parameters by the time expansion factor involved. Playback apparatus, Fig. 3 (not shown), for such a disc has a turntable (105) rotated by a synchronous motor (103) at a rotational rate which is an integral submultiple of the frequency of an A.C. source (101) energizing motor (103) and which rotational rate differs from an integral submultiple of the video field rate by a fixed small amount, e.g. 7À5 r.p.s. for 60 Hz mains energization of the motor (103) and 59À94 Hz field rate. The spiral location of the horizontal sync. signals in the record track enables detection and correction of a "locked groove" playback situation by comparing the phase of the separated replayed horizontal sync. signals with that of a reference signal in the manner described in Specification 1,526,439.

Abstract: 1372929 Automatic control of speed DAIMLERBENZ A G 22 Sept 1972 [28 Sept 1971] 44037/72 Heading GIN and G3N Apparatus for eliminating slip of the driven wheels of a motor vehicle comprises means for comparing the angular speeds of a driven and a non-driven wheel and controlling either the braking pressure or the engine torque in accordance with the difference, as modified by the actual vehicle speed and the acceleration of the driven wheel. As shown (Fig.2), the angular speed of a driven wheel 3 and a non-driven wheel 1, both on one side of a vehicle, are measured by tachogenerators 7, 5, the difference between the speeds being obtained in a comparator 11. The signal is modified at 12 in accordance with the vehicle speed, determined from the speed of the non-driven wheel 1, and further modified at 13 in accordance with the angular acceleration of the driven wheel 3, determined by differentiating at 10 the angular speed signal from tachogenerator 7. The resulting output signal is fed through a filter 14, eliminating hunting components, to (a) an OR element 20 (Fig.3) together with a similar signal from the other side of the vehicle, to allow control of the engine torque at 22 by the larger of the two signals, and (b) a level sensing element 15 for each side of the vehicle, which passes a signal if a pre-set level is exceeded. If only one element 15 produces an output signal, it is fed to the brake actuating system 17, 18, 19 for that side: if both elements 15 produce an output signal, NAND gate 16 opens switch 21 to energize control element 22 which reduces the engine torque.
