Patent GB-592222-A (GB)
Title: Improvements in or relating to piezoelectric crystal elements and units and piezoelectric transducers and devices
IPC: H04R17/00
Filed: 1944-06-21
Abstract: 592,222. Sound reproducing and transmitting devices. BRUSH DEVELOPMENT CO. June 21, 1944, No. 11837. Convention date, July 30, 1942. [Class 40 (iv)] [Also in Group XL] A piezo-electric crystal plate has its major faces parallel to the electric axis, and one of the dimensions along which piezo-electric extension takes place is substantially smaller than the other two dimensions. Fig. 1 shows the relation of the crystal element 11 to the X, Y and Z axes of a natural Rochelle salt type crystal 10. The Figure shows three such elements cut from a plate having its major surfaces parallel to the X axis and at 45 degrees to the Y and Z axes. When electrodes are applied to the small faces perpendicular to the X axis, i.e. the upper and lower edges, Fig. 1, there is no piezo-electric activity along the X axis dimension, but there is expansion or contraction along the other two dimensions of the elements. If an element 11, Fig. 3, with electrodes 13, 14 is placed between a base 21 and diaphragm 22 with the X axis parallel to the diaphragm and base, the major extension will be at right angles and will effectively operate the diaphragm. Also the surfaces 15, 16 in contact with the diaphragm and base are defined by a long dimension parallel to the Z-axis along which the displacement is accordingly small. Thus the undesired slip between the crystal and the diaphragm and base is greatly reduced. This feature is described in connection with a subaqueous compressional wave sender or receiver, Figs. 4 and 5 (not shown), which is the subject of Specification 592,217. Fig. 9 shows a compound bender element formed of two elements 100, 101 of the form as shown in Fig. 1 cemented face to face and provided with electrodes 102, 103 to produce an electric field in the direction of the X axis. This causes a major displacement along the length of the elements and a small change in thickness. The elements are chosen so that one expands while the other contracts thus producing bending. Since the contacting surfaces include only one dimension which changes in length, the curvature is about one axis only. To obtain an oppositely acting element to the one shown in Fig. 1 there is chosen the 45 degrees X-cut element cut from the natural crystal at right angles to the one shown in Fig. 1. Two such elements arranged in parallel and clamped at one end may be enclosed in a flat case for use in a deaf aid, Figs. 12 and 13 (not shown). Alternatively a compound bender element 120, Fig. 14, supported at its ends may be attached at its centre 147 to a cone 151 for use as a deaf aid. Fig. 15 shows a bender element formed of a single piezo-electric element 133 cut as in Fig. 1 having a light rigid plate 141 of aluminium or plastic cemented to one face. This causes the compound element to bend when the crystal plate 133 changes length under the influence of electrodes 13G, 137. U.S.A. Specification Re-issue 20,213 is referred to.
Patent GB-694146-A (GB)
Title: Method and apparatus for the production of multicolour prints
IPC: B41F33/00
Filed: 1951-05-21
Abstract: 694,146. Automatic registration control systems. GOEBEL AKT.-GES. May 21, 1951 [May 20, 1950], No. 11865/51. Class 38 (iv). In automatic register control of multi-colour printing machines, marks printed on a web by two printing mechanisms meet exactly when register is correct, but have a space between, when register is in error, to influence a photoelectric cell and thereby control register. In Fig. 1, a web 1 to be printed travels from a supply roll 2 to a cylinder 4 printing a first colour and through a drying chamber to a cylinder 6 printing a second colour. Simultaneously with the main printing of the web, rolls 4 and 6 also print coloured strips near the edge of the web as in Fig. 2 (a), strips 19a-22a being of the first colour and strips 23a-26a being of the second colour. If register is correct, one extremity of each coloured strip just meets the extremity of the strip adjacent to it, the other extremities overlapping as shown. Each strip is associated with a light source 7 and two photo-cells 8 controlling a pair of relays 12 through an amplifier 10. The arrangement is such that when register is correct the colour changes of Fig. 2 (a) do not influence the photo-cells sufficiently to operate either relay, but upon error in register in one sense white gaps appear on the inner strip, Fig. 2 (b), and upon error in the other sense white gaps appear on the outer strip, Fig. 2 (c). These white gaps on the inner or outer strip influence the photo-cells sufficiently to operate one of the relays 12 for a short time to run an electric motor 13 in the appropriate direction to correct register through a differential gear 17 adjusting a forme cylinder 5 relative to a main drive shaft 15. The following modifications are referred to :-(a) Additional cylinders, printing further colours, controlled by additional photo-cells. (b) A single multi-coloured strip and photo-cell controlling the speed of one printing unit which always tends to be faster or slower than that of another. (c) Use of shorter coloured strips, printed at relatively longer intervals, pairs of extremities of which just meet when register is correct as before, response of the photo-cells to the long gaps between the other pairs of extremities being rendered ineffective by rotary contact segments interrupting the relay or motor circuit during these gaps. The long gaps may alternatively be rendered ineffective by tapering the adjacent extremities of the strips and arranging the amplifier to respond only to sudden changes from or to white.

Electric fuse-boards.-A series of fuse bases, shields, or equivalent members are mounted upon transverse bars in such a manner as to provide for disengagement by a relative displacement of a bar, cr of a base &c., in the direction of the length of the base. The bases q, Fig. 1, are formed with undercut recesses z at each end to engage the transverse bars b, c; the bars are fixed at the ends on supports a by means of blocks of insulating-material d<1> and clamps d. In order to remove a base. one of the bars is unfastened and displaced ; the base can then be disengaged from the other bar while it remains in place. The bars may be so mounted that their distance apart may be varied, and the supports a may be hinged at their lower ends to allow the set of fuses to be turned down to afford access to the conductors. The contacts g, h may be mounted directly on the bars; as shown, the bar c forms the bus-bar, and the bar b is sheathed with insulating-material. In the modification shown in Fig. 4, the contacts 5, 6 are carried by the bases 2, which are supported on the transverse bars 3, 4, of which 4 forms, the bus-bar and is provided with screws 11 to engage forked extensions of the contacts 6. In a further modification. an additional bar is provided to serve as a bus-bar, and the lower contacts engage with it in the manner shown in Fig. 4. In the construction shown in Figs. 7 and 8, the contacts 21, in the form of blocks, are secured to the bus-bar 23 by screws 25, and to the bases 22 by screws 24. Before removing a base the screw 24 must be withdrawn.
