Title: Means for synchronising the phases of two alternating current voltages
IPC: H04L7/00
Filed: 1963-10-28
Abstract: 1,060,663. Phase synchronization. SIEMENS & HALSKE A.G. Oct. 28, 1963 [Oct. 29, 1962], No. 42331/63. Heading H3A. The leading edges of the pulses of a square wave pulse train 4 derived from a source 1 via a squaring circuit 2 and a plurality of binary divider units, T1, T2, T3, T4 are brought into synchronism with the leading edges of the pulses of a second square wave pulse train 20, derived from source 17 via squarer 18, by means of marker pulses derived from the leading edges of train 20 which act to either change over or block various of the counting stages in dependance on the lead or lag position of the marker pulses relative to the leading edges of the pulses of train 4 and the extent of the deviation. The leading edges of the pulses of train 20 are differentiated and applied via switch contact 26 to two gates 14 and 15. If the leading edges of the pulses in train 4 lag the differentiated pulses, these occur when the output from divider T4 at terminal 3 is zero hence gate 15 is open and the differentiated pulse is applied to dividers T1- T3 and switch these stages to their zero output condition, if they are not already in this condition. The leading edge of the next input pulse to divider T1 then switches each of the dividers to its " on " condition hence a pulse is produced at terminal 3 having a leading edge which is synchronized with the differentiated pulse to within a half-cycle time of the pulsed output from divider T1 If the leading edges of the pulses in train 4 lead the differentiated pulses these occur when the output of T4 is not zero hence gate 14 is open and the pulses are applied to gates 11, 12 and 13. If a divider stage is providing zero output at the occurrence of a differentiated pulse then the associated gate 11, 12 or 13 is open and the pulse triggers a bi-stable circuit 8, 9 or 10 which supplies a blocking input to the gate 5, 6 or 7 connected in series with the input to the divider stage. The selected gates 5, 6, 7 are thus blocked until the occurrence of the next counting pulse triggers the bi-stable circuit and hence removes the blocking voltage to the gates.

Title: Thyristor with firing current amplification
IPC: H01L29/00
Filed: 1972-09-13
Abstract: 1359076 Thyristors BBC BROWN BOVERI & CO Ltd 13 Sept 1972 [15 Sept 1971] 42490/72 Heading H1K In a thyristor there is an aperture in the main cathode region and its associated electrode through which a gate electrode makes small area contact with the adjacent base region. Within the aperture an annular zone of the same con ductivity type as the cathode region surrounds the contact area and is ohmically connected by a conductor to one or more further auxiliary electrodes which make small area contact with the base region through further apertures in the main cathode region and electrode. In operation current supplied to the firing electrode fires the auxiliary thyristor of which the annular zone forms part, and this in turn supplies firing current drawn from the main current circuit to the further auxiliary electrodes to rapidly propagate firing over the entire cathode area. The auxiliary electrode(s) may be annular or circular. In the typical device shown both the cathode region 1 and annular zone 7 are shorted to the base region via their associated electrodes 4, 8. The conductive links 9, 10 connecting zone 7 and the auxiliary electrodes overlying P + inclusions 11, 12 may be of aluminium vapour deposited on a vapour coated silica layer and may extend to make connection to other parts of the thyristor.

Abstract: 1441668 Making tubular members from sealed veneer strips SCHOCK & CO GmbH 14 Sept 1973 [15 Sept 1972] 43239/73 Headings B3B and B3T In a method of producing a succession of tubular members by peeling veneer from the periphery of a rotating log 1, the log is provided in a dampended condition and a peeling blade 7 is moved into contact with the log surface a rotary member 2 whose axis is parallel to the axis of the log and is rotated in unison therewith is provided with longitudinally extending reciprocating saw members 3 which provide a longitudinal slot in the log surface at predetermined peripheral intervals. As the log rotates strips of veneer are removed from the log surface by the blade 7, the strips so produced are coiled by a curling guide 8 adjacent the blade 7 the surface 10 of the the guide in contact with the strips 6, 6.1, 6.2 &c. making an angle of 20- 130 degrees with the tangent to the periphery of the log at the point of peeling. The curvature of the shaved strips depends on the angle of the guide with respect to the tangent at the point of peeling, the radius at which the peeling occurs, the thickness of the peeled strip and the type of log and is moisture content. The coiling effect may also be determined by the contour of the outer surface 10 of the peeling blade as shown in Fig. 3 in which the guide member is omitted, and also by the direction of rotation of the log with respect to the direction of the discharge channel along which the coiled strips travel. The action in Figs. 2 and 3 are that of a tendency to self coiling and in Figs. 1 and 4 the coiling action is assisted by a conveyer 13 and a stationary surface between which the tubular members are moved. The tubular members are subsequently conveyed to a double conveyer 15, 16 which passes through a drier 17 to remove the moisture from the coiled tubes.

Title: Method of producing extensible paper
IPC: B31F1/12
Filed: 1963-11-11
Abstract: A method of treating paper in order to improve its extensibility properties comprises the steps of mechanically shrinking a moist paper web in its longitudinal direction, and then removing most of the moisture content of the web by drying the same while being freely suspended in such a manner to allow essentially unrestricted shrinkage of the web in the plane of the paper in its transverse direction.  Any known mechanical methods may be used, for example those described in Specifications 727,261 and 846,646.  During the drying of the web while freely suspended-for example by being supported by hot air jets or cushions-the web is subjected to a drawing tension which is sufficient either to reduce the longitudinal shrinkage or to stretch the web longitudinally.  This tension may vary in different drying zones separated, for example, by presses with the tension being measured by torque-feeling means coupled to the shafts of the presses.
