Abstract: 246,872. Siemens -- Schuckertwerke Ges. Feb. 2, 1925, [Convention date]. Dynamos, regulating; motors, controlling; alternating-current motors. - In a winding of which the coils can be grouped so as to give 8n or 6n poles for running on a 3-phase supply, the 6n grouping being effected by means of a T-connection on a 3-phase system, the coils are so grouped that for the 8n pole connection the coils of the three phases are arranged in delta and that with a given line voltage the number of windings in series in one phase of the 8n pole connection is equal to the number in series in the horizontal member of the T in the 6n pole connection. The volts per winding section are thereby kept at the same value for both connections. Figs. 5 and 6 respectively show the groupings of twelve coils in mesh and T- formation to give 8n and 6n poles on a 3-phase supply connected to the points R, S, T. The ratio of the number of paralleled branches in a phase of the 8n pole grouping to that in the horizontal phase of the T is 2 : 3, while the number in series is 2 in both cases. Figs. 7 and 8 show another system in which three groups of four coils in series, Fig. 7, connected in mesh give 8n poles while the T element of the 6n pole arrangement comprises sets of two paralleled coils in series with single coils, i.e. there are four coils per phase in series in both cases. The Specification as open to inspection under Sect. 91 (3) (a) also describes, with drawings, a method of bringing out the terminals of the twelve coils with seventeen taps and connecting them to controller contacts which give 8n, 6n and 4n-pole groupings. Also the twelve coils grouped in " double star " in known manner, i.e. in three groups each of four coils in series, these groups being joined in delta with the apices of the delta connected to a common centrepoint, and the three-phase lines being connected to the centre points of the three groups. This subject-matter does not appear in the Specification as accepted.

Abstract: 793,889. Routing wood. INTERWOOD, Ltd. Feb. 1, 1957 [Feb. 3, 1956], No. 3488/56. Class 145. To enable a routing tool carried by a vertically-movable slide 22 to act on a workpiece in stages at different depths, an adjustable screw 21 on the slide co-operates with adjustment screws 10 disposed at progressively increasing heights in a rotatable turret 3 and stops 6 removably fitted in the turret co-operate with a cam bar 7 so that each time the tool slide 22 is raised from the work a spiral spring automatically indexes the turret from one stop to the next stop that has been fitted and thus brings the required screw 10 below the slide screw 21. A pivoted striker arm 8 engages an adjustable screw 19 as the tool slide nears its upper position and the cam bar 7 is then raised so that a slot in its inner side releases a first stop 61 and brings a projection 11 into the path of a second stop 6<SP>2</SP> as the turret is moved by its spring ; a spring 9 lowers the cam bar when the tool slide is again lowered and the stop can then move to the position previously occupied by the first stop. The head can be returned to its starting position by means of a handle and the projection 11 is inclined on its underside so that it rides over each stop 6 during this return movement.
