A resistor element is formed by providing a suitably shaped layer of a deoxidizing metal (e.g. aluminium, magnesium or chromium) on a silicon oxide film and causing the former to react with the latter by heat treatment. The resistance value is determined by selection of the treatment temperature (600-800 C.), the thickness of the metal layer and its shape (Fig. 7, not shown). A silicon dioxide film may be formed by steam oxidization of a silicon substrate or the substrate may be of germanium, ceramic, glass or quartz. The metal layer may be deposited through a mask or etched. After formation of the resistive layer by heat treatment electrodes are formed by deposition and etching. The current path through the resistive element may be perpendicular to its surface in which case the substrate is conductive and the resistive layer extends through to the substrate (Fig. 8, not shown). The silicon or germanium substrate may incorporate a PN junction wherein the resistance element may additionally include a second reacted layer and the P-type layer. A further embodiment comprises an integrated circuit having an NPN transistor 30, 31, 32 (Fig. 11) with reacted layers 24, 25, 26 forming resistors in the collector, base and emitter circuits.

[Also in Division B7] A mobile lift or elevator comprises a chassis 1 carrying a guideway 2 for an operator's carriage 3, the lift or elevator being supported on two sets of wheels adjacent the front and rear of the chassis respectively, the wheels of one set being associated with both steering and driving means at least one wheel of the other set being steerable and all controls being operable from the carriage. As shown, the carriage is raised and lowered by an hydraulic ram 11 which acts on a cable 12 anchored between the carriage and framework 5. The chassis comprises a frame of angle irons 4 which carries two sub-frames each provided with a pair of wheels. The wheels 16 are driven by electric or hydraulic motors 24 through spindle 20, gears 21, 22 and chain 23. The wheels 16 are each mounted in a housing 19 provided with a sleeve 19a which passes through a plate 15 and has a sprocket 39, 44 fixed thereto. The non-driven wheels, Fig. 4 (not shown), are mounted in forks rotatable about vertical axes, that of wheel 17 having a steering sprocket 35 associated therewith and that of wheel 18 being freely castorable. The lift is steered by means of its two driving wheels 16 and the non-driven wheel 17, the wheels of the two sets being steered in opposite directions respectively, by means of a reversible electric motor 27 through an endless chain 34 engaged around the sprockets 35, 44 and 39. The chain comprises two lengths of sprocket chain connected by two pairs of rods 34a. An accumulator carried by the lift is mounted on rollers 51.

An apparatus for filling sacks comprises a filling tube, sampling means, weighing means above the filling tube and means for inflating the sacks, control means being provided to initiate the operations of clamping the neck of the sack to the filling tube, inflating the sack, emptying the weighed goods from the weighing means into the sack. In one embodiment a pair of levers 8a, 8b are rotatably mounted on bearings 7 on the filling tube 1 which has a tapering hood 2 with an attached pipe 3 for sucking off dust. The levers are connected at one end by a roller 9 and at the other end one of the levers has a catch 10 which holds the lever in the upper or lower position of an arcuate slot 11. Mounted above the lever 8a is a lever 12 actuating a control valve 14. After placing a sack over the filling tube the roller 9 is lifted thus raising the lever 12 which opens the valve 14 and causes compressed air to flow to a diaphragm pressure cell 17. The pressure cell piston causes forward movement of a lever 18 which causes jaws 23a, 23b to clamp the sack against the filling tube. The lever 18 also actuates a switch 20 causing compressed air to be blown into the sack for a short time and the weighing means (not shown) to empty the goods into the sack. When the filling operation has been completed the roller 9 is returned to the lower position causing the clamping jaws 23a, 23b to return to their original position, the filled sack falling from the filling tube by its own weight. In other modifications the clamping jaws are operated by a double piston or two diaphragm pressure cells, each cell forcing one clamping jaw against the filling tube.
