Title: Improvements in or relating to electric hairdriers
IPC: A45D20/30
Filed: 1960-02-15
Abstract: 867,476. Electric hair driers. EISEMANN G.m.b.H. Feb. 15, 1960 [March 14, 1959], No. 5231/60. Class 39(3). A simultaneous variation in air thrust and heating output in a hair drier containing fan 16, Fig. 1, driven by motor 17, a heating element 24 or 25 and a switch 45, is obtained by arranging the switch in an electrical circuit so that it connects the heater to a supply either in series or in parallel with the motor. The heating element comprises two electrically separate interwound coils of wire 24, 25 mounted on a ceramic support 21 with vanes 22 disposed so that in cross-section the support is in the form of a cross. One of the heating elements 32, Fig. 3, is placed in parallel with the motor but when double pole switch 52-55-35 is thrown, pole 52 opens and pole 35 engages with the motor contact b thus placing the motor and heater in series. The heater then acts as a resistance causing the motor to slow down. Owing to the decreased current flowing the element 32 does not heat up to the same extent as it did when in parallel with the motor. In the parallel arrangement an additional heater 33 may be energised by closing switch 34 (44, Fig. 1). A main switch 36 (46, Fig. 1) is also provided, these being mounted on the handle 12 of the drier.

Title: A Method for Measuring the Configuration or Thickness of a Metal Body.
IPC: G01B15/02
Filed: 1967-02-03
Abstract: 1,180,843. Measuring spacing and thickness electrically. YAWATA IRON & STEEL CO. Ltd. Feb.3, 1967 [Feb. 10, 1966; March 29, 1966 (2); Aug.2, 1966], No.5237/67. Heading G1N. The thickness or configuration of a metal body is measured by disposing a one-end-open cylindrical micro-wave resonance cavity with its open end facing the body and measuring the resonant frequency of the cavity which is stated to depend rectilinearly on the spacing of the body from the cavity. Preferably, the open end of the cavity is surrounded by a quarter wavelength choke flange. The cavity is fed with micro-waves, frequency modulated by a sawtooth generator, and the frequency at resonance is measured and/or the frequency response curve is displayed on an oscilloscope. Many different embodiments are described. An arrangement for measuring the eccentricity of a roll is described with reference to Fig. 6 (not shown). As shown in Fig. 7, a plurality of one-end-open cylindrical cavities are arranged in a row across the width of a moving metal sheet whereby the shape of the sheet is shown on a cathode ray tube. One-end-open cylindrical cavities may be arranged on opposite sides of a metal sheet. As shown in Fig. 13, two cavities 5, 5<SP>1</SP> are spaced by a constant distance L and a servo-mechanism 47 drives an actuator 48 to position the cavities so as to keep the distances #x 1 ,#X 2  equal whereby a frequency measuring unit 45 and operating and indicating unit 46 can calculate the thickness D from the formula D = L - 2 #X 1 . In an embodiment described with reference to Figs.15 to 17 (not shown), two cavities (5, 5<SP>1</SP>) are spaced by a constant distance and a servo-mechanism drives an actuator to position the cavities so as to keep the distance (#X 1 ) of one of the cavities from the sheet constant whereby measurement of the resonance frequency of the other cavity enables the thickness of the metal sheet to be indicated. In another embodiment, described with reference to Figs.18 and 19 (not shown), each of two cavities (5, 5<SP>1</SP>) is fed with micro-waves of frequency increasing rectilinearly with time and the time taken for each to reach resonance is measured whereby the thickness of a metal plate is measured. An arrangement for measuring the reduction ratio of an iron plate during rolling is described with reference to Fig.9 (not shown). An arrangement for measuring the thickness of each part of an angle is described with reference to Fig. 10 (not shown). An arrangement, similar to that described with reference to Fig. 7, but having a row of cavities on each side of the metal sheet, is described with reference to Fig. 11 (not shown). An arrangement in which a pair of cavities, one each side of a metal sheet, are moved to scan the width of the sheet is described with reference to Fig. 12 (not shown). Reference has been directed by the Comptroller to Specification 1,118,096.

Abstract: 342,552. Impulse transmitters. CONKLIN, S. A., Box 404, Picton, Ontario, Canada. Feb. 20, 1930, No. 5694. [Class 40 (iv).] The finger-plate of a dial transmitter is declutched from the impulse mechanism at the end of the setting movement to prevent the impulse rate being interfered with by manual return of the fingerplate. The clutch mechanism is operated by a movable finger stop, and return of the mechanism is prevented until the movable stop has been operated. The fingerplate 12 is fixed on a spindle 10 rotatably mounted in the main shaft 3 which carries the usual governor drive gear and impulse wheel 7, 8. The clutch comprises a lower plate 4 fixed with respect to shaft 3, an upper plate 9 fixed to spindle 10 and an interposed plate 14 carrying dogs 15, 16 sliding in a diametral groove. The dogs have depending outer ends 15<x> adapted normally to engage notches 4‹, 4<x> in plate 4, and upstanding inner ends 17, 18 which project through radial slots in the upper plate, the dogs being pressed radially inwards by springs 19. A cone 20 fixed on spindle 10 is adapted to engage between the upstanding ends 17, 18. When the finger-plate is set, pressure of the finger against stop 24 mounted on lever 22, presses the forked inner end of the lever towards the spindle 10 so that inclines 25<x> on the lever depress cone 20 whereby the dogs are forced outwardly to release plates 14, 9 from the plate 4. The dial mechanism returns to normal and transmits impulses in the usual manner. Return of the finger-plate before completion of the setting movement is prevented by a pawl 34 and a ratchet 33 on plate 9. On movement of the finger-stop lever 22, a catch 22‹ thereon rides up the end 26<x> of lever 26 and remains locked in its operated position. At the same time, projection 35 on lever 26 releases pawl 34 to permit the dial to be returned by a spring 32, or manually, without effect on the impulse mechanism. When the impulse mechanism reaches normal, a projection 28 on plate 4 engages lug 27‹ on the lever 26 so as to release the finger-stop lever which is returned by a spring (not shown).
