Title: Protective device for electric installations according to the impedance principle
IPC: H02H3/40
Filed: 1945-04-03
Abstract: 589,933. Protective cut-out systems. ALLMANNA SVENSKA ELEKTRISKA AKTIEBOLAGET. April 3, 1945, No. 8167. Convention date, May 3, 1944. [Class 38 (v)] An impedance protective arrangement comprises a transductor (direct-current saturable reactor) fed on the D.C. side 7 with one current and on the A.C. side 3 with another current, one of such currents depending on the voltage and the other on the line current; for example the A.C. side 3 is fed through a current transformer 1, and the D.C. side 7 through a rectifier 6 from a voltage transformer 4. In the event of a short-circuit the current in winding 3 exceeds the current in winding 7 and desaturates the transductor, and a voltage is induced in winding 3 thereby energizing trip relay 8. An adjusting resistance 5 may be voltage-dependant so that the current in the winding 7 will be a non-linear function of the line-voltage. The relay 8 may alternatively be connected in a bridge consisting of two transductors and two fixed inductors, and the transductors may have a common core. When the line-voltage supplies A.C. to the transductors, the relay 8 operates on a fall in current in winding 7.

Title: Improvements in or relating to motion-converting devices
IPC: G01R13/04
Filed: 1938-03-17
Abstract: 506,211. Oscillographs. BRUSH DEVELOPMENT CO. March 17, 1938, No. 8272. Convention date, April 12, 1937. [Class 37] [Also in Groups XXIV, XIX, and XXXVII] A motion-magnifying arrangement consists of a spindle or curved plate having two portions of slightly different radius with flexible tensioned means engaging therewith as by wrapping around so that on movement of ono flexible tensioned means the spindle rolls on the other flexible tensioned means. The device is applicable to magnify the movement of a piezo-electric crystal to operate an oscillographic recording pointer or to operate an electric contact arm. If the pointer extends to the centre of curvature of the spindle, a straight-line motion is given. A piezo-electric crystal unit 2 of plate form enclosed in a casing 1 actuates a pin 14 embedded in a yielding rubber plug 16. This pin is connected to a flexible member 29 wrapping round a portion 22 of a curved-plate spindle 20 in the manner shown in Figs. 8 and 11. A bow spring 32 keeps the member 29 in tension. The spindle is supported by similar flexible members 25, Fig. 7, wrapping round the portions 21 which are of a radius differing slightly from the radius of the portion 22. These latter flexible members 25 are kept in tension by bow springs 27 and have one end 25e fixed to a support plate 23 adjustably mounted on the main body 1 of the complete device. In operation, the piezoelectric plate unit 2 causes the pin 14 to move longitudinally whereby the connected flexible member 29 rotates the spindle 20 and causes the latter to roll on the fixed flexible members 25. The spindle is fitted with a nickel pointer 4 having an ink bore leading to a pen point. The spindle may be hollow and of aluminium to reduce inertia. A vibration-damping strip 37 is provided. Adjustment of the spindle and pointer is effected by a screw 34 moving the support plate 23 towards or away from the main body 1. Specification 318,934, [Class 40 (iv)], is referred to.

Title: Improvements in web winding
IPC: B65H19/10
Filed: 1944-05-02
Abstract: <PICT:0572625/IV/1> <PICT:0572625/IV/2> <PICT:0572625/IV/3> In apparatus for winding webs continuously into rolls, the transfer of the web 9, Fig. 1, from a full core 26 to the core 25 of a new roll is effected by the aid of controlling marks 54 on the web which actuate light-sensitive or other control devices for causing actuation of a knife 67 which severs the web going to the full roll and directs the leading end of the cut web to the core 25.  The control devices may be relays actuated by the marks 54 on the web and also by marks 80 on the outside of a short length of web 26, Fig. 2, which is wound on the core prior to its being mounted in the arms 19 of the roll support, there being three sets of arms 19, 20, 21, each fitted with adjustable bands 37, 38, 39.  The main driving-bands 28 are passed over rollers 14, 15, 16, 31, 32, 33, driven by a motor 34 and tensioned by the weighted roller 32.  As shown in Fig. 1, there are two scanning devices D, D1 which cause energization of an electromagnet 73 which releases the springcontrolled cutting-device 67 when the marks 54 are printed on a master web, led from a roll to or coming from the calenders of a papermaking machine, by means of a printing-roller 58 and an impression roller 59 which is brought into operation by an electromagnet 62 on operation of a switch 64.  The switch is operated when the roll 26 is full, and an electromagnet 63 is operated at the same time to operate a valve 56, which causes compressed air to spray an adhesive material from a reservoir 49 to produce an area 61, Fig. 4, of a self-sticking adhesive of the kind described in Specification 555,707, [Group XVI].  A shield causes a gap in the area 61 at the position occupied by the mark 54 which is arranged in advance of the area 61 by a length equal to the distance between the roll 25 and the scanning-device D. The roll 25, Fig. 2, is wound with a web 76 coated on the inside with a self-sticking adhesive adapted for use in joining up a new roll to the expiring web of an old roll when the rolls are used in a printing &c. machine.  A layer 79 of this adhesive is applied to the front edge of the web 76, which is secured by tabs 78.  The core 25 is driven at the same speed as the web prior to the severing of the web and the starting of the winding of a new roll which occurs when the adhesive area 61 becomes attached to the layer 79.  In place of light-sensitive scanning devices, there may be employed electric contacts engaging conducting marks 54 used in place of colour marks.  The mark on the core member may be dispensed with and only one conducting area used.
