A model is steered around a closed track by moving a guide having the same shape as the track at right-angles to the direction of motion of the model. The model may be attached to a concealed endless belt by a vertical wire or to a concealed carriage running on a rail by a horizontal wire. Lateral movement of the belt and rail respectively move the model athwart the track. The model is not steerable in parts of the track which are parallel to the direction of lateral movement and these are accordingly reduced to a minimum. In another form, a horizontal wire carrying the model is slidably mounted in a carriage moving on a fixed guide. The free end of the wire slides on a movable guide and transmits the lateral relative movement of the guides to the model. The circuit diagram of a coin-freed machine is described. If during its run a model touches a hazard, it completes a circuit through the stepping coil of a selector switch which lights an appropriate score lamp.

Manufacture: the material is 48% Fe, 52% Ni, with a diameter of 0À001-0À03 inches, the highest signal to noise ratio coming from wires of 0À009-0À015 inches. The wire is made by heat treating and work hardening a conventional wire, as in Fig.9. The wire is taken from reel 86 and annealed at furnace 102 to make it uniformly soft, and then passed to a hardening station 91 where it passes through induction coils separated by water cooling sprays, Fig.10. The first induction coil heats the wire to 1720F, and successive coils to lower temperatures. The sprays cool the shell to about 1100F. Rollers 92 establish a strain of 2¢% in the wire, the result being that the core and shell have different coercivities. In another method of manufacture wire is drawn from a rod at a high enough temperature to produce a fine grain structure and then work hardened by stretching and twisting the wire to and fro. If the wire is left in a twisted state a helical easy axis is produced. Fe-Ni alloys containing Co may also be used.

Filed: 1964-10-05
Abstract: Groups of corrugations 3 are formed in a strip 2 of cardboard, Fig. 1 (not shown), by a machine comprising a toothed roller which pushes the strip between pairs of rods to form the peaks of the corrugations.  The rods of each pair are urged together to compress the corrugations so formed.  Between the groups of corrugations flat portions 4 in the strip are provided for by flat sections on the roller where the teeth are omitted.  A distance member, replacing the rods in that area of the machine, may be formed by rods lying side by side.  Alternatively, the corrugations may be formed by plungers which press the strip between pairs of stationary rods.  The rods then move past the plungers to compress the corrugations.  The flat portions in the strip are provided by the plungers remaining inoperative between successive movements of the rods.  The strip forms part of a box blank (see Division B8) when it is glued to a further strip 1 of cardboard, Fig. 2, (not shown).
