Abstract: 739,782. Electric irons. HOOVER, Ltd. May 21, 1954 [May 25, 1953], No. 15074/54. Class 39 (3). [Also in Group XXII] In making a sole-plate for an electric iron having cast in it a sheathed heating unit 10 comprising a coiled resistance wire in magnesium oxide in a metal sheath, one or more openings 18 are formed in the sheath adjacent each end for impregnation of the insulant with a moisture repellent fluid, e.g. a liquid silicone, by dipping it therein. The openings 18 are formed by saw cuts or broaching at opposite sides, and after impregnation, the element is degreased by a vapour of an organic solvent and placed in a die-casting machine. The openings 18 may lie within the casting or may extend above it. In the latter case, the parts with the openings 18 may be removed, leaving enough siliconeimpregnated insulant in place to form a seal against cooling liquid used in machining the sole-plate.

Title: Flaw detector for continuous sheet material
IPC: G01N21/89
Filed: 1957-05-15
Abstract: 808,020. Photo electric flaw detection. NATIONAL RESEARCH COUNCIL. May 15, 1957 [May 18, 1956], No. 15410/57. Class 40 (3). A flaw detector for continuous sheet material comprises a coincidence circuit which indicates the simultaneous receipt of a signal from two photo-electric means. White paper 10, Fig. 1, is scanned by the combined image of two photocells 13, 14 which receive light from mercury vapour lamps 11 reflected from the paper on to rotating mirrors 44 to be reflected by or passed through half mirror 18. Signals from electron multiplier 21, Fig. 2 (which may be part of the photo-electric means 13) are amplified and filtered at 23, 25, 27 and presented to the positive and negative Schmitt circuit discriminators 29 and 30. A similar circuit for the photo-electric means 14 is traced through 22, 24, 26, 28, 31 and 32. Discriminators 29, 30, 31, 32 provide a pulse in response to a positive or negative pulse from the photo-electric means which is more negative than or in excess of a predetermined voltage. The high-pass filters 25, 26 attenuate the mains frequency and lowpass filters 27, 28 the high-frequency noise generated by the electron multipliers and amplifiers. The outputs of the positive and negative discriminators are fed to the coincidence circuits 33, 34, respectively, which provide pulses when signals are received simultaneously from both circuits. These are added at 35 and used at 38. The gating generator 37 connected to coincidence circuit 36 supplies an output signal only while the combined image of the photo-electric means 13 and 14 are both imaged on the paper 10.

Inventor: GROSSFIELD KARL
IPC: F04B43/073
Filed: 1959-05-07
Abstract: 888,379. Diaphragm pistons; engine valve gear. NATIONAL RESEARCH DEVELOPMENT CORPORATION. June 17, 1960 [May 7, 1959; June 18, 1959; Sept. 30, 1959; Jan. 25, 1960], Nos. 15669/59, 20955/59, 33148/59 and 2558/60. Classes 122 (1) and 122 (2). [Also in Groups XXVIII and XXIX] The diaphragm 1, Fig. 1a, of a vapouroperated diaphram motor is shaped at least in part in the form of two isosceles triangles having a common base or having their bases separated by a rectangle, Fig. lb, of flexible impervious material, e.g. rubber, and the figure so formed has its edges clamped by frames 2 and is bisected longitudinally by rigid spine members 3, 12, 13 connected to the diaphram material articulated to each other at adjacent ends 17, 18, 19 to allow of relative longitudinal movement and pivoted at 15, 16 to the frames 2; the triangular portions of the diaphragm being rendered transversely inextensible, e.g. by securing textile strips across the rubber sheeting; the rectangular portion being rendered inextensible in both the transverse and longitudinal directions and a surplus of rubber sheeting being provided within the boundary of the frames 2 to allow movement of the diaphragm out of the plane containing the clamped edges. The splines are secured to the rubber sheeting by a rubber rib 4, Fig. 2e, associated with a rubber tube 5 on either side thereof and which serves to press the diaphragm in its extreme position against the lowermost part of the motor chamber wall 6. Control of supply and exhaust of vapour to and from chambers A, B, Fig. 6, into which the motor casing is divided by the diaphragm 1 is effected by valves 37 . . . 40, Fig. 7, mounted on a common stem 51 which is positioned by a cam 52 engaging a groove 53 in a valve stem control device 36. As shown, valves 37, 39 are open, whereby vapour admitted at 32 traverses a duct 34 leading to chamber B and chamber A is exhausted past valve 39 into a duct 50. At the end of the stroke the valve stem is moved so as to close valves 37 39 and open valves 38, 40, resulting in a return stroke. For maximum efficiency, vapour is cut-off from the working chamber before the end of each stroke by closing a normally open solenoid valve 33 in the supply duct 32. To this end coil 45 of valve 33 is in series with a coil 47 into which passes a magnetic rod 48 carried by the reciprocating rod 11.

Title: Wide range radio frequency tuner
IPC: H01F21/06
Filed: 1955-06-01
Abstract: 775,851. Coaxial cavity resonators. ALLADIN INDUSTRIES, Inc. June 1, 1955 [June 9, 1954], No. 15696/55. Class 40 (8). [Also in Group XL (c)] A wide range (e.g. 54 to 890 Mc/s.) tuner comprises a tuning coil 2 having non-uniform inductance per unit length which forms part of the inner conductor of a coaxial resonator. The coil 2 is preferably printed on an insulating cylinder 3 and is longitudinally movable within a conductive sleeve 16 which protrudes through the end 14 of the resonator 10. The portion of the coil extending into the resonator is capacitively coupled to two spaced sleeves 7, 8 which are, in turn, conductively coupled to the walls of the resonator. Insulation between the sleeve 8 and the coil 2 is provided either by an air gap or by a coating of insulant on the coil or the inside of the sleeve. Energy may be coupled to the tuner either by a further sleeve 21 around the coil 2 or by a loop 25. At the lower end of the frequency range the coil 2 is in its extreme left-hand position with the portion 6 of maximum turns density situated between the sleeves 7, 8. The resonant frequency is determined by the inductance between the sleeves. An increase in frequency is obtained by moving the coil to the right. As the frequency increases the coaxial cavity becomes effective as a resonator loaded by the capacitance existing between the coil 2 and the sleeve 7. A conductive tongue 18 on the end of the coil 2 ensures that this capacitance gradually decreases as the coil is moved further to the right. The initial capacitance between the sleeves 7 and 8 may be adjusted by means of a sliding conductive tube 28 guided by an inner tube 22 of insulating material. In a modification, Fig. 8, the sleeve 16 is capacitively coupled to the end wall 14 of the resonator. For this purpose the sleeve is provided with a flange 86 spaced from the end wall by means of insulating screws 87. A sheet 88 of mica acts as a dielectric and prevents contact between the sleeve and the resonator wall. A sleeve 89 envelopes the portion of the coil 2 outside the resonator. Transfer of energy to and from the resonator is effected by connections between a lead 90 to the flange 86 and the wall of the resonator.
