Title: Improvements in or relating to electrodynamic pickups
IPC: H04R9/12
Filed: 1945-08-27
Abstract: 602,114. Gramophone pick-ups. SOUNDSCRIBER CORPORATION. Aug. 27, 1945, No. 21917. Convention date, Aug. 8, 1944. [Class 40 (iv)] In a moving coil gramophone pick-up, means secured to the magnetic frame restrain the rear of the armature which carries the coil from undesirable vertical vibrations. As shown in Figs. 1 and 2, a pair of Z-shaped magnetic frame members 11, 12 having polepieces 13, 14 are clamped to a magnet block 10. Between the polepieces is mounted an armature A preferably of plastic material, the square end lug 30 of which fits into an aperture in a front cushion member 21 mounted on the ends of the polepieces. The rear of the armature is supported by another cushion 23 fitted to one of the fixing screws of the members 11, 12. Mounted on the armature are a stylus 32 and the coil 37 with its iron core 38. Provision is also made for a " hum-bucking" coil 3 to be fitted on the armature to compensate for disturbance due to stray fields. A transverse brass wire 45 (Fig. 5), the ends of which are cemented to the members 11, 12, engages the rear cushion 23 and prevents undesirable vertical movement of the armature. This wire also maintains the central slit 28 of the cushion closed about the rear lug 31 of the armature. Specification 539,534, [Group XXXVIII], is referred to.

Abstract: 1,104,322. Radiation pyrometry. ROLLSROYCE Ltd. May 17, 1966 [May 24, 1965], No. 21999/65. Heading G1A, A pyrometric temperature measurement of a turbine blade in a gas turbine engine compensates for changes in emissivity of the turbine blade with temperature by arranging for the pyrometer to receive also radiation which has been reflected off the surface of the blade a change in emissivity then being off-set by a change in reflectivity. Radiation from a laser is directed on to the blade and the reflected radiation and radiation emitted by the blade is received, preferably, upon a single solid-state detector in the pyrometer. The intensity of the laser is made equal to that of a black-body radiator at the temperature of the blade in order to effect the compensation. The laser intensity is either maintained constant at this value or small permitted changes are monitored by a second detector which corrects the signal from the first. The path lengths from the laser to the first and second detectors are made the same. Filters may be inserted in the radiation paths to select a particular wavelength in the infrared at which the apparatus is most sensitive to temperature changes. The laser beam may be modulated and a further detector sensitive to the modulation can then distinguish the reflected laser beam from the emitted radiation in order to make compensation for the change in emissivity. A helium-neon gas or solid state laser may be used.

Abstract: 276,365. British Thomson-Houston Co., Ltd., (Assignees of Randolph, C. P.). Aug. 23, 1926, [Convention date]. Electric hot-plates. - An electric waffle iron comprises two cooking plates 10, 11 hinged together at 12, 13, and having a sheathed heating-unit 26, 27 on the back of each plate, means for clamping the units on the cooking plates, and covers 18, 20 secured to the plates and fitting over the heating-units, supporting-means, such as legs 19, being secured to one of the covers. The plates 10, 11 are identical in construction so that, when the upper plate is inverted, the single and bifurcated hinge lugs 14, 15 interengage as shown in Fig. 3. The lugs 14 are recessed and the recesses are grooved to receive the convolutions of an armoured cable 45 which connects the supply contacts 38, 39 on the stationary lower portion of the iron to the upper heating element 26. The ends of the cable 45 are held in the recesses by the covers 18, 20 which are bolted to the plates by screws 22. The cover 20 is secured also by the lifting handle 23.

Abstract: 738,008. Check valves. WOODHEADMONROE, Ltd. Sept. 2, 1953 [Sept. 2, 1952], No. 22077/52. Class 135. [Also in Group XXXII] The invention relates to a valve assembly of the kind which provides for controlled flow in either direction between the cylinder and reservoir of a shock-absorber (see Group XXXII). The outer peripheral portion of a valve plate 28 is urged by its own resilience in one direction to engage a seating 27. An inner marginal portion of the plate 28 (bordering a central hole in the plate) is urged by a spring 32 in the opposite direction on to a seating 30. In operation, on extension of the shock-absorber piston (not shown), the outer peripheral portion of the plate 28 lifts to permit upward liquid flow. On compression, the inner marginal portion of the plate 28 lifts from the seating 30 to permit downward liquid flow through the hole in the plate. The valve plate 28 comprises a plurality of flexible discs, one of which may have a slot to provide a permanent metering flow. The spring 32 is a Belleville washer, but may be an ordinary spring washer or a coiled spring.
Patent GB-598008-A (GB)
Title: Cutting oil
IPC: C10M169/00
Filed: 1945-08-28
Abstract: A cutting oil comprises 25-95 per cent. by volume of petroleum distillate, 5-75 per cent. by volume of naphthenic acid and from 0.5 to about 5 per cent. by weight of metal naphthenate.  The metal naphthenate is dissolved or colloidally dispersed in the oil and is a naphthenate of magnesium, calcium, aluminium, lead, manganese, copper, iron, cobalt or nickel or a mixture of two or more such naphthenates.  The petroleum distillate may be lubricating oil, gas oil, kerosene or kerosene distillate.  Both the petroleum distillate and the naphthenic acid may be employed in the crude form or each may be separately refined by treatment with sulphuric acid and removal of sludge.  Alternatively the crude petroleum distillate and the naphthenic acid may be mixed together and the mixture refined with sulphuric acid.  Sulphuric acid refining may be followed by treatment with caustic soda solution to neutralise any free sulphuric acid or sulphur dioxide.  If desired the metal naphthenate may be formed in the mixture of petroleum distillate and naphthenic acid by contact of such mixture with an oxide, silicate or other reactive compound of the desired metal.  Suitably this reactive metal compound is one, such as hydrated magnesium silicate, which is capable of acting as a filter aid and also as an adsorbent material for decolorizing the mixture.
