Abstract: 814,123. Piezo-electric crystals. POSTMASTER GENERAL. May 25, 1956 [March 18, 1955], No. 8029/55. Class 40 (8). A piezo-electric or ferro-electric crystal element, e.g. of quartz, ethylene diamine tartrate, barium titanate or Rochelle salt, has cantilever arms which extend symmetrically from a common portion and means for exciting the arms into vibration in a flexural mode, the arms being so constructed and arranged that all the reactions in the region of the common portion are substantially balanced. The element may be of H-form cut from a rectangular quartz plate, the normal of which is rotated 5 degrees from the Z axis of the parent crystal towards the Y axis, the breadth being parallel to the X axis. The crystal is supported by terminals T1, T2 near its centre of gravity which connect with silvered electrodes, and by which the element is excited to vibrate in a flexural mode of frequency 2,676 kc./second at 20 C. The electrodes are disposed on the faces of the crystal and are indicated by shading in the drawings. The inner surfaces of the arms may also carry electrodes if desired. In an alternative construction the cross-section of each arm of an H-element increases with distance from the bridge-piece, so that the element vibrates at a lower frequency, viz. 1,930 kc./second at 20  C. In a further construction the element is of zig-zag form as illustrated in Fig. 2, or may have arms with more zig-zag bends than shown in that Figure. Alternatively, the element may comprise two C-shaped members arranged back to back, or may be of H-shape with lateral saw-cuts in the bridge portion, or may comprise symmetrically arranged cantilevers loaded at their free ends.

Abstract: 548,895. Automatic control systems for winding reels. BRITISH THOMSON-HOUSTON CO., Ltd. June 27, 1941, No. 8084. Convention date, June 27, 1940. [Class 38 (iv)] Tension in material wound from one reel to another by dynamo-electric machines 22, 23 respectively driving one reel and braking the other, is maintained constant at an adjustable value by an armature-reaction excited dynamo 31 furnishing an E.M.F. in parallel with the field of the braking machine and in series with the field of the driving machine, a control field 31d winding energized in accordance with the sum of the armature currents of the machines, being connected across resistances 32, 33 in each armature circuit. A rise in voltage across these resistances occurs as the diameter of the driven reel increases and the control winding 31d, which is opposed to a control field winding 31c which determines the tension, causes a fall in the output voltage of the dynamo 31 whereby the field of the braking machine is reduced and that of the driving machine is increased to maintain the tension constant. The machines are in parallel with a generator 24 the excitation of which is varied to change the speed of winding. Tension is maintained at all times by a booster generator 30 excited by the armature-reaction machine in proportion to the tension during running ; a resistance 35 is inserted when not running to reduce the tension. The system can be accelerated without change in tension and is reversible, relays 27, 28 effecting the required circuit changes being operated by a manual switch 36.
