Title: Improvements in and relating to means for checking the loading of wagons, lorries and the like
IPC: G01G19/08
Filed: 1924-12-11
Abstract: 226,530. Cobb, W. J. Dec. 19, 1923, [Convention date]. Void [Published under Sect. 91 of the Act]. Apparatus fitted to railway and road vehicles. - The weight loaded into a railway wagon, lorry or other vehicle is indicated by a device which depends for its action upon the deflection of the vehicle springs. The device may comprise telescopic parts opened out by a spring the inner part having a pointer registering with a graduated scale on the outer part. When used in connection with a railway wagon a bridgepiece is placed across the rails under the centre of the wagon and the device is supported thereon by means of wedges. The final adjustment is made by screwing up a false head into contact with the floor of the vehicle until the pointer indicates zero. The weight loaded into the lorry may then be observed during the loading operation. The device is calibrated to allow for the depression of the track rails, flexibility of the under-frame of the wagon and flattening of the wheels. In a modification, suitable for use with various standard types of vehicles, an additional indicating pointer actuated by a link is arranged to move over a semi-circular dial bearing a set of graduations for each type of vehicle. In a further modification, Fig. 3, where the device is attached beneath the centre of the wagon, a movable member 2a is bolted to the under-frame 19 of the wagon and carries a worm 20. When the under-frame descends due to the loading, the worm rotates a pinion 21 and a pointer 23 to indicate the weight of the load. Zero adjustment is made by means of nuts 26, 27 and a screw 25 bearing the worm. The lower part of the device is supported by girder structures 35, Fig. 4, supported from the axle boxes at each side of the wagon and united by a central cross structure 41. In a modified arrangement two of the devices are used, one at each end of thewagon.

Abstract: 1505653 X-ray scanners EMI Ltd 25 June 1975 [11 July 1974] 30712/74 Heading H4F Display apparatus, for representing both scanned body sections and notional sections interpolated from scanning data, comprises storage means for the absorption coefficients of elements of respective body sections, means for weighting corresponding elements of said sections to produce data for corresponding elements of a notional section, and means for displaying any of said sections. The weighting function is dependent on the position of the notional section which is preferably midway between two scanned sections, but may be shifted by a position control knob (not shown) which alters the weighting function. The storage means may comprise a video disc store having tracks in two zones, each with its own record/playback head. Each representation of a body section is recorded as two fields F1, F2 on adjacent tracks, and adjacent representations are recorded in different zones so that they may be simultaneously reproduced. Also stored on the disc may be a second set of the same representations modified for example by limiting to maximum and minimum levels. Computer 8 derives each representation from data from known X-ray scanning apparatus and stores eight lines of a representation (generated during one revolution of the disc) in register 11 for output at a faster rate to a sector of disc store 12. The circuit is controlled by a control computer 9 which at the reproduction stage operates pick up heads 6, 7 and gate circuit 15. Circuit 15 includes multipliers (16, 17 Fig. 4 not shown) which weight pairs of input coefficients with complementary functions which may be retrieved from "read only memory" (19), the weighted coefficients being summed before being displayed on TV screen 21. Each field derived from computer 8 has 320 active lines (compared with 280 on conventional TV display) so either the first and last 20 lines of information may be discarded, or the 320 lines transformed to 280 by any suitable means.

A clothes washing machine having a tub 10 containing a washing mechanism 12, a drive shaft 14 for the mechanism, a pump 36 for emptying the tub, a motor 15 common to but having individual driving means for the pump 36 and mechanism 12, and a single control means for connecting the shaft 14 and pump 36 individually or jointly to their respective driving means comprising means for moving the pump into and out of engagement with its driving means and operated by axial movement of a control lever 48, and rotatable cam means for moving the washing mechanism driving means into and out of engagement with the driving-shaft 14 and operated by rotational movement of the lever 48. The pump 36 is pivotally mounted on a shaft 38 and is normally urged by a spring 43 to a position wherein a friction wheel 39 on the motor shaft engages a friction wheel 42 of the pump. Mounted on the pump is a shift bar 46 terminating in a sloping cam face 47 and the shift bar can be actuated to disconnect the wheels 39, 42 by inward movement of the control lever 48. During pump operation the lever 48 is held retracted from the shift bar 46 by a detent flange 55 co-operating with a notch 56 in the lever. By slightly raising the lever 48 a spring 57 is allowed to pull it inwardly. The lever 48 is also capable of limited rotational movement in a slot 52 in the skirt 11 of the machine casing, one end of the lever 48 being reduced as at 50 and capable of sliding and swinging movement in an opening in a bracket 51. A rack bar 22 is given a to-andfro motion by being eccentrically pivotally mounted on a worm-wheel 20 driven by a worm 19 connected through couplings 40 and a shaft 18 to the motor 15. The rack bar 22 terminates in a rack 23 which is supported by means of a saddle 25 for movement into and out of mesh with a pinion 24 fixed on the shaft 14. The saddle 25 is pivotally secured to a plunger 27 urged outwardly by a spring 30 and having a rounded head 33 co-operating with a cam 32. The cam 32 is provided with a forked arm 53 through which the lever 48 passes freely.
