Title: Improvements in motor lorries and other road or rail vehicles for conveying goods
IPC: B60P1/38
Filed: 1928-04-05
Abstract: 293,997. Mundy, F., JÀ, and Solomon, C. April 5, 1928. V e h i c l e fittings.-Relates to wagons or motor lorries of the type fitted with a movable floor 1 to facilitate loading and unloading. The floor 1, which may consist of a band of rubber and canvas, balata and canvas &c., is fixed at its ends on drums 2, 3, and is supported throughout the length of the vehicle on rollers 4 which rotate freely on rigid axles 5 spanning the frame 6. Each roller 4 may be formed in two or more lengths mounted on the axle 5 by roller or ball bearings, and the axles 5 may be supported at one or more intermediate points by longitudinals such as 7. The sides of the wagon may be fitted with chamfered metal strips projecting over the edges of the floor 1 to prevent loose material such as sand &c. getting underneath the floor. The drums 2, 3 may be rotated by chain and sprocket gear operated from different positions by detachable handles, or it may be driven from the vehicle motor. The band 1 is longer than the vehicle, so that the part stored on the forward drum 2 is sufficient to permit complete discharge of a load of loose material without the use of a wall plate on the band. A spindle 8, Fig. 5, of the winding gear carries a short screw 12 with end stops 14 which limit the travel of a nut 13 so that the gear can only wind through a definite range.

Title: Method and device for measuring forces, applicable especially to automatic weighing
IPC: G01G7/06
Filed: 1960-06-17
Abstract: 919,771. Measuring weight electrically; electric selective signalling systems. PESAGE AUTOMATIQUE. June 17, 1960 [June 18, 1959], No. 21356/60. Class 40 (1). A weight is measured by opposing it by the force produced by a current-carrying coil in a magnetic field, balance being ascertained by a differential capacitor with movable plates attached to a support carrying the weight. The current through the coil at balance is proportional to the weight. Construction (Fig. 1).-A rod 7, supported by two resilient plates 10, 10a, carries the object 9 to be weighed at one end and, at the other end, a coil 6 located in the circular gap 5 of a permanent magnet 2. Vertical displacement of the rod 7 is indicated by the change in capacitance between fixed plates 14, 14a, and movable plates 15, 15a mounted on the rod 7, as measured in a normally balanced A.C. bridge circuit, whose output signal indicates by its magnitude and phase sense the extent and the direction of displacement of rod 7. Circuitry (Fig. 5).-The current through coil 6 is obtained from a power amplifier 21, and is automatically adjusted to such a value that the p.d. across a resistor Ro also carrying this current is substantially equal to a series opposing stable E.M.F. V, the difference between these voltages being converted to A.C. by vibrator 24, amplified at 22 and demodulated at 25 before amplification at 21. If this current is too small to centralize the moving plates 15 of differential capacitor 14-15, an output signal is obtained from its bridge circuit which is fed to a stepping device 27, comprising a relaxation oscillator which successively energizes a series of thyratrons each controlling a relay Re 1  ... Re n  introducing a resistor R 1  ... R n  in parallel with Ro. When the moving plates 15 are recentralized the stepping device 27 stops, and the current through coil 6 is indicative of the weight of the object 9. In another embodiment (Fig. 6, not shown), the H.F. output from the capacitor bridge is use to supply the current through coil 6.

Title: Improvements in or relating to a method of and apparatus for drying hygroscopic plastic material containing sugar
IPC: C13B50/00
Filed: 1945-08-22
Abstract: Hygroscopic plastic material containing sugar, such as molasses, is dried by spreading it as a thin film on to a moving surface heated to a temperature above the boiling point of the material.  The dried film is scraped off the surface before charring can occur and is simultaneously agitated to break up froth.  The drying surface is preferably an internally heated drum.  Molasses containing 80 per cent solids is introduced, through pipe 6 and nozzles 6a, between drums 1 which are heated by 100 lbs. per sq. inch steam and are rotated once every 8 to 9 seconds.  Doctor blades 8 remove the dry material on to plates 9 down which it flows to collecting trays 10. While it is being scraped off the drums, the dry frothy mass is agitated by a plurality of blades 11 which are reciprocated over it by rods 12 and bell-cranks 13, the arrangement being such that the paths <PICT:0608137/III/1> <PICT:0608137/III/2> of the blades overlap.  The product has a moisture content of 0.75 per cent and a temperature of about 200 DEG  F. as it reaches the trays.  If necessary, the relative humidity of the atmosphere surrounding the product must be adjusted to less than 33 per cent before it is cooled below 130 DEG  F. and crushed.  Solutions of corn or malt sugar or other solutions composed chiefly of invert sugar may also be treated. A blast of air or other gas may be used to effect agitation in place of reciprocating blades.
