Abstract: 1326169 Rolling mills NIPPON KOKAN KK 26 Aug 1971 [29 Aug 1970] 40053/71 Heading B3M In the cold rolling of metal strip having successive lengths joined end to end to form a continuous strip, or having desired changes in width or thickness, the mill is automatically controlled so that the tensile stress in the strip remains constant even during changes of thickness or width. The width of the strip is measured by a device 11, as the strip passes between two mill stands 1 and 2, its tension is measured indirectly by a load cell 3 and a screwdown 7 associated with the stand 1. With the aid of relays 13 and 14, the changes in thickness #h/h and width #w/w of the strip are processed in order to provide a signal  at 22 corresponding to the desired total tension in the strip (where To is the tension before any changes in width or thickness). This signal is compared with the actual tension measured by meter 12, and any error signal is directed to a controller 23. The controller varies either the roll speed of stand 1 or the screwdown of stand 2 in a sense to reduce the error signal to zero, thereby maintaining the tensile stress in the strip uniform.

Filed: 1959-12-02
Abstract: 924,992. Frictional igniters. T. RUETZ. Dec. 2, 1959 [June 1, 1959], No. 40993/59. Class 75 (3). A lighter comprises a flint disc and a friction wheel, the flint disc having on its periphery a recess in which the friction wheel engages. To rotate the flint disc to compensate for wear a worm 5 within a hollow shaft 5a drives a worm-wheel 4 on the flint disc axle 1. Ratchet toothed coupling members 6, 7 connect a pin 8 with the shaft 5a. The spigot end of the pin extends into the hollow end of the shaft 5a. A spring 10 extends between a collar 8c on the pin and the member 7 and a spring 11 extends between the collar and an end bearing 9 for the pin. A bifurcated extension 14 on the member 7 engages a pin 15 on a spring-urged plunger in a cylinder 17. An extension 16a on the plunger extends through the casing wall 19 and retracts when the cover 23 is pressed in the direction of the arrow P1 to ignite the lighter. The member 7 turns through one tooth. The member 6 is held by a spring pressed pawl in housing 34. When the pressure on the cover is released the extension 16a returns under spring pressure and rotates the member 6 causing the shaft 5a, worm 5, worm-wheel 4 and the flint 3 to rotate. As this is more than is necessary to take up wear and reverse rotation being prevented by the pawl engaging the member 6, the worm 5 moves longitudinally compressing the spring 11. This movement continues during continued actuation until the end of the pin abuts the bearing, the extension 16a then remains retracted. The friction wheel 12 rotates when the cover is pressed, the cover being connected to a front cover part 28 by a pin 12b and the cover part pivoting on the friction wheel axle 12a. A lever 25 is mounted between the axle 26 and a pivot 24 on the wall 19. The cover is urged to closed position by a spring 27 between a part 19b on the wall 19 and the axle 26. The flint disc and worm-wheel 4 are readily assembled and dismantled by mounting them on the axle 1 having flat end parts la, 1b which engage in slots in flanges secured to the casing walls, the axle being rotated through a right angle to lock the axle by a lever 32 secured to the axle 1. If the worm and worm-wheel are self-locking then the pawl may be omitted. A slip coupling may be substituted for the ratchet coupling and a spring inserted to urge the flint disc and friction wheel into constant engagement.

Title: Improvements in or relating to harmonic wave generators
IPC: H03K3/45
Filed: 1960-11-29
Abstract: 931,012. Harmonic generating circuits. PHILIPS ELECTRICAL INDUSTRIES Ltd. Nov. 29, 1960 [Dec. 2, 1959], No. 41000/60. Class 40 (6). A harmonic generator comprises a class AB push-pull transistor amplifier 4, 5 supplied with the fundamental frequency wave by means of transformer 3 and having in the collector circuit a parallel tuned circuit 7, 8 tuned to the fundamental frequency and including an inductor 6 with a saturable core of ferrite material. A common emitter-circuit resistor 9 is provided. The arrangement is such that at each instant when the current through the saturable nductor 6 is passing through zero the inductance increases, producing a voltage pulse both in the inductance 6 and in a secondary winding 12. The pulses in the secondary winding 12 are amplified by a class C push-pull transistor amplifier 13, 14, the output of which feeds a number of harmonic frequency filters 15-18 via coupling windings 22-29. In the case of filters 15, 16 which select even harmonics, the corresponding coupling windings for the two transistors 13, 14 are connected in the same direction so as to cancel out odd harmonics, whereas for filters 17, 18 which select odd harmonics, the corresponding coupling windings are connected in opposite directions so as to cancel out even harmonics. According to the invention, diodes 32, 33 respectively, are included between the collector electrode of each of the transistors 4, 5 and the parallel tuned circuit 7, 8, the current pass direct of each diode being the same as that of the collector current of the associated transistor. Each diode cuts off when the voltage at the corresponding end of the tuned circuit swings low, preventing heavy damping which would otherwise be imposed on the tuned circuit due to the low impedance of the corresponding transistor, the transistor being driven to saturation at this point. During the periods when each of the transistors 4, 5 is operative the other is cut-off and its collector follows the negative-going voltage at the end of the tuned circuit 7, 8, connected thereto, the voltage across the corresponding diode being zero. The sharp pulses produced by the saturable inductor 6 are in a positive direction for the cut-off transistor and cause the corresponding diode to cut-off, so preventing loss of the higher frequency components of the pulses due to the interelectrode capacities of the cut-off transistor. The transistors 4, 5 and 13, 14 may alternatively be connected in Class B.

In a brake mechanism comprising a pair of shoes 12, 13, a drum 10 and means 20 for moving the shoes into engagement with the drum, an adjustable strut 51 having a moving part 54, 56 is located between adjacent shoe ends and has surrounding it and operatively connected thereto a coil spring-type clutch 70 which is adapted when tightened to grip and rotate the movable strut part and means are provided to connect the clutch to a lever 40 movable on actuation of the brake. As shown, on actuation of the brake with the vehicle moving in the reverse direction the shoe 12 moves in the direction of arrow A so that lever 40 swings to the left on pivot 45 to which is also secured a lever 46, the latter thus swinging downwardly. A link 48 connects with clearance lever 46 to lever 50 which is rotatable about the movable strut part 56 and is biased upwardly by spring 66. One end of the clutch spring 71 is engaged in an aperture 73 of the lever 50 so that on downward movement of the lever 46 the lever 50 rotates to unwind the spring on the part 56 to release its grip and position it in a new location. On subsequent actuation of the brakes with the vehicle moving in the forward direction the shoe 12 moves in the direction of arrow B, lever 40 moves to the right and levers 46, 50 move upwardly to tighten the spring clutch 70 about the part 56 to grip the same. The continued movement of these parts will rotate the stem 54 of the adjustable strut to extend the same and thus adjust the brake. The brake may be adjusted manually by means of the toothed wheel 58 fixed to part 54, 56.
