Abstract: 1,252,387. Data storage. BURROUGHS CORP. 14 April, 1970 [9 July, 1969], No. 17652/70. Heading G4C. In a dynamic magnetic memory in which binary "1" is indicated by a change in polarity of the magnetic carrier at a clock time and binary "0" by no change in the polarity at a clock time, pairs of polarity changes 10 are recorded on the carrier at each binary "0" to compensate for the effects of data crowding and to reduce the effective minimum spacing between polarity changes. Figs. 1A-1C shows the effects of data crowding on a non-compensated system. The output pulses (Fig. 1C) produeed in response to the data (Fig. 1B) become out of phase with the data and also suffer from amplitude distortions A1 due primarily to the finite width of the gap of the playback head causing the output pulses to be asymmetric, i.e. the trailing edge takes longer to fall to zero than the leading edge takes to rise from zero. The effect of the compensatory pairs of transitions 10 is shown in Figs. 1D and 1E. The transitions decrease the time taken by the trailing edge of the output pulse to fall to zero and reduce the phase lag and amplitude variation of the output pulse but do not produce any significant signal on playback since, because of the small period between them they are effectively suppressed by the same crowding effect, which, unchecked, produces the deterioration in the data pulses. The distribution of the compensatory transitions 10 may be adjusted for optimum effect in accordance with the parameters of the system but they are spaced by a distance substantially less than the minimum spacings between data transitions and are asymmetrically arranged around their associated clock pulse. Successive pairs of transitions 10 corresponding to successive binary "0"s are spaced by an amount equal to the minimum spacing between data transitions. A circuit for producing the compensating transitions is illustrated in Fig. 2. When the data input is "1" and a clock pulse occurs, gate 16 is activated and flip-flop 22 is set, to produce the data pulse at the record head 30. However, if the data input is zero, gate 16 is blocked and gates 26 and 28 are enabled by the output of the inverter 24. The clock pulse is then passed through gate 26 to activate the record head which is switched again when the clock pulse, via delay circuit 30, passes through gate 28. Thus a pair of transitions are produced spaced by a time equal to the delay introduced by the device 30. A threshold.detector 39 is used in the output circuit to distinguish data pulses from noise and any ripple produced by the compensating transitions.

Abstract: 1,257,369. Pipe couplings. L. BANIDES, and J. DEBEAURAIN. 11 April, 1969 [25 Nov., 1968], No. 18745/69. Heading F2G. A method of connecting and providing insulation between two tubular parts 2, 4 of a conduit 1, the ends of the two parts having diameters such that the end of one part can fit into the end of the other part with a clearance, comprises fitting the end of the part of smaller diameter into the end of the part of larger with, within the clearance, a sleeve 3 of an electrically insulating material so that the sleeve extends beyond the free ends of the parts 2, 4 and changing the diameter of the end of at least one of the parts in order to clamp the sleeve 3 between the parts. As shown, the sleeve 3 of synthetic rubber or other plastics material is gripped between the sleeve 4 and conduit 1 by expanding the conduit or reducing the sleeve so that adjacent milled or threaded surfaces penetrate into the surfaces of the sleeve 3. The sleeve 4 is formed with a collar 5 which is abutted by a coupling flange 6. In modifications, (a) the flange 6 is integral with the sleeve 4, the latter and conduit 1 being pinned together by a screw of insulating material and there being a rubber gasket between the flange 6 and the coupling flange of an adjacent conduit and a ceramic sleeve within the portion of the insulating sleeve 3 extending beyond the end of the conduit; the flange 6 may be replaced by a nut or the conduit may be flanged, and (b) an insulating sleeve having a collar at each end thereof is gripped between the tubular portion of a valve and an internal sleeve which is expanded radially or, alternatively, by radially compressing the tubular portion.

Abstract: 1,258,055. Axial-How fans. SMITHS INDUSTRIES Ltd. May 16, 1969 [May 21, 1968], No .24223/68. Heading F1C. In a heating or cooling system, particularly for a motor vehicle, a fan comprises a pair of radial tubes 14, 15, Fig. 1, of circular cross-section each provided with a long continuous slot 16 or a number of small slots arranged end-to-end. Alternatively, each tube may be provided with two long slots or two rows of small slots, arranged parallel to one another and angularly spaced by about 20 degrees. The slot 16 is angularly spaced from the leading edge of the respective tube by approximately 120 degrees; the leading edge being determined with respect to the direction of rotation 26. Compressed air supplied through a fixed cap 19 and a running seal 18 passes along each tube and out through slot 16 in a direction substantially tangential to the outer surface of the associated tube to induce a flow of the ambient air axially through the fan in the direction 21. The compressed air also passes out through a series of radial holes 6 to form a curtain which reduces leakage around the end of the tube. The flow of the compressed air to the tubes is controlled by a thermally-responsive valve (not shown) controlled by the temperature at, e.g., the vehicle cooling radiator outlet. The tubes are of cadmium-plated mild steel, and the slots 16 are each defined therein between a sidewall of an elongated channel (8), Fig. 2 and 3 (not shown), in the outer surface of the respective tube and one side of an elongated strip (22) located in the channel. Preferably, the ratio of external diameter of the tube to the width of the slot 16 in about 250 to 1, and the ratio of the length to the diameter of the tube is about 5 to 1. In a modification, Fig.4 (not shown), suitable for use in a vehicle heating and engine cooling system, the hollow interior of each tube is divided into two longitudinal passageways (27, 28) each of semicircular cross-section and each associated with a respective elongated slot (20, 30). Thus, for a fixed direction of rotation of the fan the induced airflow through the fan can be reversed merely by altering the passageways into which the compressed air is delivered, to thereby cause air to be delivered into the vehicle or discharged therefrom.

Abstract: 1301433 Measuring wheel unbalance electrically Gebr HOFMANN GmbH 18 June 1971 [11 Nov 1970] 28729/71 Heading G1N The unbalance of a wheel rotating on its axle on a vehicle is measured by resting the wheel suspension on a stand incorporating a force transducer 1, Fig. 1, and feeding the unbalance signals through a filter network 6-10 whose output has an inverse square law relationship with the input in respect of frequency and therefore represents the unbalance mass independently of speed of rotation. The phase of the output signal is also maintained at 90 degrees in advance of the input and is used to fire a stroboscopic lamp 16 when the unbalance mass is at bottom dead centre. The two wheels of a vehicle on a common axle may be tested simultaneously using a common support stand 17, 18 Fig.2, separate wheel driving motors 23, 24 and feeding the velocityadjusted unbalance signals through a potentiometric network 29 to convert the unbalance components as measured by load cells 19, 20 into unbalance components in the planes of the wheels. Unbalance components producing wobbling movement of the wheel are measured by a force transducer 36, Fig.3, contacting the wheel mounting e.g. the brake drum, through a spring  37. The signals are fed to the measuring network 2 of Fig. 1 and the unbalance removed by fitting diametrically opposite weights to the inner and outer edges of the rim of the wheel.

Abstract: 1304547 Photoelectric speed measurement SHELL INTERNATIONAL RESEARCH MAATSCHAPPIJ NV 13 April 1970 17510/70 Heading H4D The speed of a moving surface is measured by splitting a beam of monochromatic plane polarized light into two beams, which are caused to overlap on the surface and detecting the rate of variation of the intensity of the light reflect from the surface. In a ship's log, a beam of light from an argon laser 1 is split into two parallel beams 3, 4 and these are refracted by lens 6 mounted in the hull 7, to intersect at the focus 8 in the sea water. The output of a photomultiplier 12 is connected to a frequency analyser 13, e.g. oscilloscope or computer. Mask 11 is provided at the focus of lens 10 to shield the detector from stray light. The mask 11 is positioned by inserting a bi-prism (14) into beam 3 between lenses 6 and 10. This produces a beam parallel to beam 3 near the axis of lens 10 and directed in the opposite direction. The aperture in mask 11 is then positioned to allow the beam refracted through lens 10 to pass through. (Fig. 3, not shown). The output of the analyser 13 may be connected to a computer which averages the Doppler frequency over a period of time, e.g. 15 minutes, to reduce the effects of turbulence. The system may also be applied to measuring the velocity of material, e.g. metal strip, fabric, plastic during manufacture. Reference has been directed by the Comptroller to Specification 1,249,540.
