[Also in Division B3] Anisotropic magnetic particles distributed in a binder formed into a tubular member are aligned by means of a core or magnet lying within the tube co-operating with magnets arranged outside the tube. As shown, Fig. 2, the tubular magnet is extruded by means of a die 9 and immediately passes between the poles 12, 13 of a D.C. energized electromagnet to align the particles within the binder which is still soft. A soft-iron core 10 is arranged within the tube to concentrate the magnetic field and is supported on the central member of the die. The poles of the electromagnet are shaped to the outside of the tube, Figs. 1 and 3 (not shown). In a modification, Figs. 3 to 5 (not shown), the poles of the electromagnet are in the form of grooved wheels arranged so that they rotate as the tube is moved between them. A groove may be provided in the wall of the tube by means of a cutting wheel, Figs. 6 and 7 (not shown), to aid in orientating the resulting magnet when used in a small D.C. motor. In a further modification. Figs. 8 and 9 (not shown), a slit is cut in the wall of the tube so that the centre core may be supported by members extending through the slit. The orientation groove or slit may be formed by a triangular plate attached to the extruding die, Figs. 10 and 11 (not shown). The core supported within the tube may itself be a magnet and may comprise the polepieces of an electromagnet the coil of which is located outside the tube and coupled to the polepieces by flat magnetic limbs which pass through a slit cut in the tube. The magnetic particles may comprise Ba, Pb, Sr or Mn-Bi ferrite and may be combined with Fe. The binder may be a polymer elastomer or rubber such as PVC, methylmethacrylate, urea formaldehyde, vinylacetate, vinylformaldehyde, buna N, or polyethylene or a silicone or a non-magnetic metallic material.

Abstract: 1,111,140. Making plate fin tube modules; jointing by tube expanding. HUDSON ENGINEERING CORPORATION. 12 Dec., 1966 [7 Feb., 1966], No. 55606/66. Headings B3A and B3J. A plate fin tube module, Fig. 11, is made by feeding plate fins 33 over the ends of tubes 36 supported in spaced apart parallel relation to form a stack, the assembly being vibrated to assist the movement of the plate fins over the tubes. As described, tubes 36, Fig. 1, are pushed from a rack 44 by a pusher 47 on to a horizontal beam 49b on which the tube ends are gripped by a head 62, Fig. 13, which is moved along the beam by an endless chain 67. When the tubes have been drawn on to the beam a sufficient distance, a second head (75) (Fig. 14, not shown) is moved forward and the head 62 moved back again until the opposite tube ends fit tightly over projections (74) on the head (75). Intermediate portions of the tubes are supported by movable heads (62a-62c). After vertically raising the beam by a fluid actuator 50 and moving it sideways, tapered guide pins (79) (Fig. 17, not shown) are mounted in the upper ends of the tubes over which plate fins 33, sheared from a strip 30, are fed to lie on top of the head 62, which is gradually moved downwards thereby forming a stack of fins on the tubes. The fins are guided by side members 55 extending along the length of the beam. When a stack of fins has been so formed, the beam is moved downwardly and sideways whereupon the tube ends are again clamped by the head 62 which moves the tubes forward until the opposite unfinned ends have passed through a movable plate (87) (Fig. 19, not shown) and against a stop (88). In this position, the tubes are expanded against the plate fins by drawing rods (91), with bullets (93) secured to their free ends, through the tubes, buckling of the fins being prevented by flanges 56 on the side members 55. Finally, the beam is raised into alignment with a conveyer 95 on which the completed module is transported. The plate fin feeding means 31 and the guide roller 38 are movable along a platform 39 so that they can be positioned near either of the two beams 49a, 49b.

The lever L is mounted on a stationary pivot 23 and comprises resilient arms 21, 22 of which the latter blocks the wheel 14 when the lever L is in the second position. The arm 21 abuts a pivot spindle 24 of a control lever L 1  and biases the wheels 12, 13 into meshing engagement. The control lever L 1  has an end l which is engaged by a setting stem 31, inward displacement of the stem bringing a stud 27 on the lever L 1  into contact with the arm 22 to move the wheel 12 into the second position. In this position, the wheels 12, 13 remain slightly meshed to facilitate re-engagement. Reverse rotation of the wheels is prevented by a freely pivoting pawl 15, and the lever 5 carries a magnetisable block 9 to hold the lever alternately against banking pins 10a, b which are fixed to a permanent magnet 10. The timepiece also comprisesa snap-on, frictionally mounted cannon pinion to permit setting while the wheel 14 is blocked. An alternative arrangement is envisaged in which the wheel 12 is mounted on an lever which is pivoted about the shaft 19 of the wheel 13 so that the wheel 12 moves about the latter in a planetary manner. The pawl 15 is then replaced by a conventional pawl and the wheel 12 is biased into engagement with the wheel 13 by a spiral spring. The stem 31 may be provided with an abutment to block the wheel 14 directly.

Abstract: 1,255,789. Transistor oscillators. PILLAR CORP. 2 Dec., 1968 [30 Sept., 1968], No. 57005/68. Heading H3T. [Also in Divisions G3 and H2] In an A.C./D.C./A.C. frequency, multiplying convertor system for supplying a resonant load, e.g. an induction heating coil in parallel with power factor correction capacitors, the invertor stage is triggered by an oscillator the frequency of which is automatically adjusted to maintain a required output voltage and peak power as the load varies. Alternatively the resonant circuit may be in the output stage of the convertor per se and an external load connected thereto.  Oscillator.-Fig. 11 illustrates a typical unijunction transistor oscillator circuit to produce pulses for the control of the SCRs and wherein a plurality of inputs A 7 , B 7  &c. from feedback circuits and connected to line X, vary the base potential of a transistor 65 more positively or more negatively to increase or decrease the oscillator frequency or block it, according to the requirement of the respective feedback system. In the absence of any input signal the line X will be negative due to R67, thereby causing a high charging current of C64 (the charge on which causes UJ61 to conduct at a certain level) and a high frequency output from the oscillator. Thus the feedback system which produces the most positive potential at line X predominates and operates to reduce the oscillator frequency, and turns on an indicating lamp indicating which system is controlling. A negative input at terminal E sets the minimum frequency limit.  Trigger signals for SCRs.-The oscillator output appears across a resistor (128) (Fig. 13, not shown) and comprises - ve going spikes each time the UJ transistor fires, which pulses are stretched and momentarily turn OFF a transistor (129) producing + v@ going spikes at its collector which trigger an integrated circuit flip-flop (132). The flip-flop outputs, at half the oscillator frequency, drive respective transistors (138), (139) which provide the firing pulses for the negative and positive groups of SCRs respectively.
