Abstract: 248,402. Schlotter, G. A. March 2, 1925, [Convention date]. Helico - centrifugal apparatus; casings; impeller blades.-In turbines or pumps wherein the rotor g works in a casing F that widens from its middle in both directions, the rotor vanes and the guide vanes located on both sides thereof are spherical or ellipsoidal surfaces, all having the same diameter. The curve g of the rotor hub is tangential to the circular arcs N of the spherical stator bosses N. Similarly, the contour FTF of the casing is made-up of three arcs of circles. The left-hand side of the Figure shows alternative contours. The centres or centres of gravity of the rotor vanes lie in a circle in the plane H-H, the point b indicating one such centre and the arc B indicating the curvature of the vane struck therefrom. Geometrical methods of determining the various surfaces of the turbine are described for rotors having six and ten vanes respectively. A modification is described wherein the guide vanes on the discharge side direct the fluid radically outwards into a spiral casing, the flow in the spiral casing being opposite in direction to the rotation of the rotor.

Title: Electro-acoustic transducer
IPC: H04R23/00
Filed: 1942-05-01
Abstract: 558,680. Electro-acoustic apparatus. PHILCO RADIO & TELEVISION CORPORATION. May 1, 1942, No. 5893. Convention date, June 13, 1941. [Class 40 (iv)] [Also in Group XL] An electro-acoustic transducer, in particular a gramophone pick-up or a microphone, comprises a non-magnetic vibratile member having at least one short-circuited turn inductively coupled to an inductance element forming part of the frequency-determining circuit of a radio-frequency oscillator, the output of which is thereby frequency-modulated in accordance with the inductance changes brought about by the vibrations of the non-magnetic member. Fig. 1 shows a pick-up 9 with an armature 8 which may comprise a single short-circuited turn, and is inductively coupled to an inductance 1 forming part of the tuned-grid circuit of an oscillator valve 3. The resulting frequencymodulated output is detected in an ordinary amplitude-modulation receiver 12 which is slightly detuned, or in a frequency-modulation receiver 13. If the latter is designed to operate on a wider frequency-band than that which can be supplied from the oscillator a frequencymultiplier 14 may be interposed. A microphone comprising a cone carrying a moving coil consisting of one or more short-circuited turns may be substituted for the pick-up 8. Fig. 7 shows a pick-up armature 65 made of channelsection light-weight non-magnetic metal having an apertured end which forms a short-circuited turn adjacent an inductance coil 60 provided with a comminuted iron core and shell 59 to concentrate the flux. The armature is mounted on a shaft 61 carrying an arm 62 to which the stylus 63 is secured, the shaft being mounted in a tone-arm structure as described in Specification 552,019, [Group XL]. Fig. 8 shows another form of pick-up in which the vibrating member 70 including a ring 71 forming a single-shortcircuited turn may be made from an aluminium casting and is housed in crossed recesses formed in the body and cover of a moulded case. The inductance coil is positioned in a circular recess beneath the ring 71, and a tuning condenser 68 is housed in another recess. The member 70 is held in rubber bearings 73, 74, and a projecting lug 76 on the ring 71 may be embedded in rubber to provide for damping and centring the armature. The Specification also describes the use of the pick-up in the radio-gramophone combination forming the subject of Specification 558,704. The Specification as open to inspection under Sect. 91 further refers to transducers producing amplitude modulation of the radio-frequency oscillations by variation of the high-frequency resistance or the capacity of a tuned circuit. This subject-matter does not appear in the Specification as accepted.

Title: Animated doll
IPC: A63H13/04
Filed: 1970-02-06
Abstract: 1293334 Animated dolls MATTEL Inc 6 Feb 1970 [5 May 1969] 5926/70 Heading A6S A doll is operated by a mechanism which either causes the doll to walk or causes its arms to pivot about shafts joining the arms and shoulders. An oscillator bar 44 is pivoted at its lower end to the rear of a frame 30, and is caused to oscillate laterally by means of an off-centre pin (42) (not illustrated) which is mounted on a gear 40 and engages in a longitudinal slot in the bar. Drive from an electric motor 36 is transmitted to the gear 40 to cause it to rotate. A coupling 52 has two positions, one in which it may engage the frame 30, by means of a lug 60 in a slot 62, and a second in which it may engage the oscillator bar 44 by a lug 56 and a slot 58. In the first position, i.e. as shown in Fig. 2, the oscillation of the bar 44 is transferred to a shaft 66, supported in the torso 82 by bearings 68, 70, by a slot 74 and pin 72. The movement of the shaft 66 is in turn transferred to the arm by a pin 64 mounted in the shaft 66. When the coupling 52 is in the second position, i.e. the lug 56 is engaged in the slot 58, all the oscillation of the bar 44 is transmitted to the torso 82, to which mechanism 28 is attached at the rear, no motion relative to the torso is imparted to the shaft 66, and hence the torso is caused to execute a walking motion by means of which the legs, attached to the frame 30 by couplings 32, 34, are swung so as to produce' a walking motion. A model toy such as a bandalove or bat and ball may be attached to the arm to simulate the operation of such toys by a child. Also disclosed is a means by which both arms of the doll may be caused to move.
