Title: Energy Translating Means
Inventor: BEAVER WILLIAM DEAN
IPC: H03H9/56
Filed: 1967-04-11
Abstract: 1,187,472. Electromechanical filters. WESTERN ELECTRIC CO. Inc. 11 April, 1967 [11 April, 1966; 17 June, 1966], No. 16539/67. Heading H3U. A band-pass filter comprises, Figs. 1, 2, an AT-cut quartz crystal wafer 14 having deposited thereon gold electrode pairs 16, 22, the electrodes 18, 20 of pair 22 being connected by leads 24 to a source S and the electrodes 10, 12 being connected by leads 24 to a load, the wafer vibrating in shear mode to transfer energy between the two pairs 16, 18. The electrodes 10, 12, 18, 20 are sufficiently massive to create significant energy binding or trapping so that the amplitude of vibrations imposed by the source S is concentrated in these regions of the wafer situated between the electrodes of each pair, the amplitude of vibrations decreasing exponentially with increase of distance from each electrode pair. This decrease is such that the edges of the wafer do not affect the operation. However, the distance d between the electrode pairs 16, 22 is such as to place the pairs in each other's effective acoustic field so that they affect one another significantly so that acoustic energy is guided between them. The bandpass is widened and narrowed by respectively reducing and increasing the distance d, or by reducing or increasing the mass-loading of the electrodes. Additional pairs of masses, not functioning as electrodes, may be provided on the wafer between the electrode pairs (Figs. 22, 23, 26, 27, not shown). In a modification (Fig. 21, not shown) the crystal wafer is of magnetostrictive material.

Abstract: 616,965. Measuring speed. PRICE, D. R., and METROPOLITAN-VICKERS ELECTRICAL CO., Ltd. Nov. 23, 1942, No. 16590. [Class 40 (i)] [Also in Group XXXV]. A speed responsive device for producing an electrical quantity representive of the speed comprises a gyroscope with a mass rotating on an axis AB in a casing 2 mounted for precessional rotation about an axis 0 upon a base member 1, which is rotated about an axis C, D at a speed which is to be indicated or controlled electrically. Carbon contact resistances are contained in sleeves 7, 8 which are adjustably supported on resilient wires 11, 12 surrounded by tubes to limit lateral displacement. The force of precession is balanced by a motor device energized by the current or voltage obtained through the variation in pressure on the carbon resistances when the gyroscope precesses. As shown, a coil 27 is wound upon a copper tube 25 supported on a lever 17 secured to the gyroscope casing. The tube passes over a core 19 on a yoke 20 and through an aperture in a yoke 21, the yokes being connected at their ends by permanent magnets. The driving motor, the coil 27 and the carbon resistances are connected to separate terminals on a block 30. Fig. 3 shows one way in which a device 35, intended to give an indication or control action dependent upon the angular velocity of a structure on which the apparatus is mounted may be connected to the apparatus. The carbon resistance 7a, 8a are connected in differential circuits so that when equal, no current flows through the coil 27 and the device 35, which are in series. As applied to an arrangement described in Specification 616,516 for controlling the speed of a motor, the gyroscope is responsive to the speed of the motor.

Abstract: 862,555. Stator winding machines. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Aug. 30, 1957 [May 30, 1956], No. 16740/56. Class 35. In a core winding machine, radially movable fingers are held against the core ends so that they assist in shaping and supporting the end turns and the fingers are on a common support so arranged that they can collectively be withdrawn from the completed end windings. The stator laminµ 1 in a retaining shell 2 is gripped between finger supporting rings 16, 17 and mounted in saddle members of a winding machine. Each ring 16, 17 has radial slots equal in number to the number of core slots and a fingers 31, 32 is mounted in each ring slot and held by a wire or rod 42 disposed in a circumferential groove 43 in rings 16, 17 and by a ring 45 or 46 of L section clamped on rings 16, 17. The machine shown winds a four-pole concentric winding, an unwound slot at the centre of each pole having a bar 67 temporarily placed therein to assist in keeping the end windings clear of the stator bore. Wire is fed into the slots in an unspecified manner and passes over the radially inner part 31 of a finger as shown in Fig. 9. The shape of this part of the finger depends on the number of coils the finger supports and some fingers need their slots to be enlarged into ring 45 or 46 as shown at 61 in Fig. 3. On completion of the winding the stator unit with rings is removed from the machine and the two clamps 52, 54, 56 and 53, 54, 56 which have held rings 16, 17 in place are released and as they move axially away from the core the fingers can tilt and be drawn clear of the end turns. To permit this tilting a slot 41 is provided in the heel of each finger also rings 45, 46 are movable relatively to rings 16, 17 by an amount determined by shoulders 74 (Fig. 3) on the studs 48, 50 forming parts of the abovementioned clamps. The device for causing relative angular movement between the stator and wire layer also is not described. Specification 862,054 is referred to.
