Abstract: 1,070,982. Measuring wheel unbalance photoelectrically. MOBIL OIL CORPORATION. Nov.25, 1963 [Nov. 30, 1962; Jan. 14, 1963], No.46454/63. Headings G1A and G1X. Unbalance detecting apparatus for vehicle wheels comprises a dynamometer roller supporting a wheel under test so that the latter carries its normal share of the vehicle weight, and means to measure oscillations of the wheel toward or away from the roller and indicate the amplitude of the frequency component proportional to the amplitude of unbalance vibrations. Light from a source 26 Fig. 3, passing the periphery of a wheel, 22, under test is detected by a photo-cell 30. The A.

The sensor Fig. 6 comprises two inertia masses 222, 224 on the ends of flexible strips 218, 220 mounted to flex in perpendicular directions. Each strip carries a strain gauge resistor 226, 228, connected by cable 208 to a measuring console. The sensor unit is attached to a part of the wheel suspension which vibrates when the wheel is rotated, due to wheel unbalance, with the plane of one strip parallel to the plane of the wheel to sense its static unbalance, whilst the other strip senses dynamic unbalance. A switch 70 Fig.4 on the measuring console selects the static or dynamic unbalance signal from strain gauges 226, 228 and integrates it at 70, to obtain a vibration speed signal. This is amplified at 74, filtered at 76 and squared at 78 to five stroboscopic lamps 82, 84 at the time of the leading edges of the squared pulses. The output from filter 76 is also fed to a peak detector 90 controlling a digital indicator 96. The squared pulses are also differentiated at 98 and the positive parts fed to an astable multi-vibrator 100 whose frequency is set to correspond to a maximum wheel speed. If this speed is exceeded the multivibrator 100 is blocked and a lamp 114 is energised.

The ink is transmitted to the ribbon either directly, or by a writing wick 5, or a writing pen 15 or a felt pad to the roller 3 towards which it is biased by a spring 6 and the roller 3 transfers the ink to the advancing ribbon 1. For translation the ribbon 1 is nipped between the roller 3 and either a spring biased member 2 or a roller 14 biased by a spring 13. Ink may be transmitted to at least one transfer roller which transfers the ink to the roller 3. The device 4 is in the form of a cartridge shell 4a which accommodates an ink-filled rubber receptacle 17. The shell 4a receives a head 4b which presses a wall portion of the receptacle 17 against the shell 4a and conveys ink via its bore 23 to the wick 5. Ribs or lobes (22), Fig. 6 (not shown) are provided on either the head 4b or the shell 4a to facilitate the pressing of the receptacle portion. The bore 23 is defined by slots formed into a star-like configuration Fig. 7 (not shown).

Abstract: 1,083,263. Safety helmets. L. P. FRIEDER. Nov. 26, 1964, No. 48173/64. Heading A3V. The adjustable headband of a helmet comprises tubular front and rear portions 59, 69 connected by draw straps 93, 99 which are sewn to the ends of portion 69 and pass into the portion 59, emerging through slits 91 in the outer wall of the tube to be connected by a buckle 95. Alternatively the straps 93 and 99 are integral and the buckle 95 is disposed at one side of the helmet. To maintain a minimum spacing between the front headband 59 and the helmet shell 21, irrespective of variations in the overall headband size by means of the buckle 95, inelastic loops 101 stitched to the ends of headband 59 are looped through slots (not shown) in plates 105 screwed to the shell, the combined lengths of the loops and the headband 59 being less than the distance between the screws 107 (Fig. 9, not shown) measured along the curved surface of the shell. The forward end of fore and aft head strap 45 is anchored to the shell and the headband 59, Fig. 2, by being passed through a slot 47 in a plate 51 screwed to the shell and then between a saddle strap 61 and the headband to which it is stitched, and being stitched to itself and the headband at 57 to form a loop 48. The headband is padded with e.g. foam rubber 77 and reinforced behind the saddle strip at 81. The draw strap 99 passes freely through the loop 48. The head strap is adjustable in length by means of a buckle (not shown) securing it to a separate loop 65 at the rear of the helmet similar to the loop 48. The forward ends of diagonal headstraps 45 are anchored to the shell and the headband by being passed through horizontal slots in the plates 105 and the rear ends differ from that of the fore and aft headstrap in that saddle strips 111 allow less relative movement between the headband and the loops 65 than the saddle strip 67 does, straps 67 and 111 preferably being elasticated. The shell is lined with shock absorbing material such as foam rubber 115.

Abstract: 1406627 Liquid dispensing apparatus VAPOREX 24 Oct 1972 [12 June 1972] 48851/72 Heading T In a method and system for handling the vapour of a volatile liquid, e.g. petrol, at a dispensing station petrol in underground tanks 18 is pumped via lines 16 to island dispensers 14 and then via one line in a double hose to vehicle tanks, the vapour displaced from the tanks passing via the  other line and lines 22 back to a tank 18. The vapour in the tanks is then circulated via lines 30, 32 through a cooling chamber 26 cooled by a refrigerator 36 whereby the difference in pressure between the tanks and the chamber maintains the circulation, possibly aided by pumps. The vapour in the chamber condenses and condensed liquid and dense cooled vapour gravitates back to the central tank 18 via vapour and condensate standpipes 44, 46. To prevent escape of vapour to the atmosphere, the maximum vapour pressure must not exceed the order of 2 ounces per square inch, and pressure switch 40 actuates the refrigerator at or below this pressure while, should the vapour handling system fail, relief valve 54 vents vapour at a pre-set level, e.g. 11b per square inch pressure.  Tanker 55 fills the tanks 18 via lines, 56, 60 and returns excess vapour via lines 62, 66 to the tanker. If the tanks are above ground, they are provided with vapour pressure controlled heaters to prevent "breathing" due to changes in atmospheric temperature.
