[Class 82 (i)] In a method of extruding a sheath of lead or of a lead alloy, e.g. an alloy of lead with tin, antimony, or cadmium, À005-À05 per cent of sodium is added to commercial lead prior to its extrusion for the purpose of purifying the lead and preventing its re-oxidation while it is in the extrusion press. A trace, about À001 per cent of sodium remains in the lead. The sodium is preferably added to the molten commercial lead as a lead alloy. This may be introduced in a finely divided state in the extrusion cylinder of the lead press or may be spread uniformly in the form of a foil over the surface of the old charge of metal in the cylinder A or may be introduced into the lead melting pot. The Specification as open to inspection under Sect. 91 states that other metals than sodium having an affinity for oxygen may also be used in the above way. This subjectmatter does not appear in the Specification as accepted.

Title: Apparatus for regulating voltage in alternating current distribution systems
IPC: G05F1/32
Filed: 1928-06-01
Abstract: 322,775. Pollak, J. E., (Ganz-Fele Villamossagi Reszvenytarsasag). June 1, 1928. Divided on 322,199, [Class 38 (ii), Electric currents, Converting &c.]. Electric transformers; systems depending on static transformers. - The output voltage of transformers with tapped secondaries is controlled by two chokes I, II each with a closed flux path, or by one choke with two closed flux paths, the paths having main coils f<1>, f<2> and auxiliary coils g<1>, g<2>. The main coils are in series across tappings L', L<2> on the secondary of the .transformer with their junction connected to a line L<3> on which the voltage is regulated by short-circuiting one of the coils g<1>, g<2>, gradually over a resistance k', k<2> or instantaneously by a switch. When neither coil is shortcircuited, voltage drop dependents on load current in the main coils 'is avoided by so interconnecting the coils g<1>, g<2> that the currents in the coils g<1>, g<2> equalize the flux in the cores I, II, equal fluxes producing equal and opposed voltages in the coils g<1>, g<2>. The interconnection is broken simultaneously with the short-circuiting of either coil, the switches h being mechanically connected as shown. The resistances k', k<2> may be water resistances. More than two chokes with auxiliary coils successively short-circuited may be used. In a modification, the branches of the cores I, II adjacent in Fig. 1 are united to form a centre limb of a single for the coils f<1>, f<2>, g<1>, g<2>. To avoid the voltage drop dependent on load when neither coil g', g<2> is short-circuited, a coil on the centre limb is short-circuited by a switch positively connected to the switches for the coils g<1>, g<2> so that the short-circuit of the coil on the centre limb is broken when either coil g', g<2> is short-circuited. Reference has been directed by the Comptroller to Specification 126,744, [Class 38 (ii), Electric currents, Converting &c.].

Abstract: 1,215,047. Feeding webs; packaging- machines. A. SCHMERMUND. 25 June, 1969 [19 July, 1968], No. 34599/68. Headings B8C and B8R. Webs 3 and 103, e.g. of flexible wrapping material, pass from bobbins 2, 102, carried by a support 4, to respective pairs of co-operating rollers 16, 17 and 116, 117 which are coupled to a common drive shaft (23, Fig. 2 (not shown), through two electromagnetic couplings (31), one for each pair of co-operating rollers. In operation, one of the electromagnetic couplings is energized so that the web 3 is drawn from bobbin 2 by the rollers 16, 17 and is fed past cutters 14, 15 which are operated in known manner to cut predetermined lengths of material from the web; when a photo-electric detector 300, 301 senses the end of the expiring web 3 the operative coupling is de-energized and the other coupling energized so that the web 103 is drawn from bobbin 102 by rotation of the rollers 116, 117. Bobbin 2 can then be replaced, the new web being threaded down to the now stationary rollers 16, 17 which can be spaced apart by operating a handle 33 to facilitate the threading and which will again be activated when the trailing edge of the web 103 is sensed by a further photo-electric detector 400, 401. Thus it is not necessary to stop the machine, e.g. a wrapping machine, to which the web is fed when a bobbin has to be exchanged, nor is it necessary to glue the trailing edge of one web to the leading end of the next. The cutters may be of the rotating type or of the reciprocatable type as shown; if the latter the web is arranged to be intermittent so that cutting can take place whilst the web is stationary.
