IPC: B24B3/26
Filed: 1984-02-14
Abstract: The apparatus for grinding twist drills comprises a shaft and a grinding wheel which has a grinding surface and is rigidly secured to the shaft. The apparatus comprises also a drill-guiding body, which faces the grinding surface and is axially spaced from it and axially immovable relative to the grinding surface. The drill-guiding body is formed with a plurality of guiding passages for guiding twist drills differing in diameter toward the grinding surface. At least one guide lug is aligned with each guiding passage of the drill-guiding body and adapted to extend into a flute of a twist drill extending through the associated guiding passage. All guide lugs are mounted on a guide lug carrier, which is mounted to be axially movable between the drill-guiding body and the grinding surface and which is biased toward the grinding surface by a spring. At least one abutment consisting of a material which has a higher hardness than the grinding wheel is secured to the guide lug carrier and has an abutment surface which is parallel to and engageable by the grinding surface. This arrangement ensures that a constant distance from the guide lugs to the grinding surface will be maintained during the grinding operation in spite of the wear of the grinding wheel and the original shape of the grinding surface will be restored.

Abstract: 551,548. Non-reflecting coatings; glass; antihalation films. KODAK, Ltd. (Eastman Kodak Co.). Jan. 6, 1941, No. 184. [Classes 97 (i) and 98 (ii)] [Also in Group XXIII] An article of low reflectivity comprises a transparent body, e.g. of glass or film base, of relatively low refractive index, e,g. less than 1.5, a superimposed layer of transparent material, e.g. urea-formaldehyde resin or polystyrene of relatively high refractive index gradually diffused into the body to avoid a sharp reflecting surface and having a thickness greater than one quarter the wavelength of the light for which low reflectivity is desired and an upper layer or layers of a transparent material, e.g. ethyl cellulose or cellulose caproate having such a low refractive index and of such a thickness as to reduce reflectivity by interference. The diffused coating may comprise a number of layers each of lower refractive index than the last. A subbing may be applied between the base and this coating and, if of the same refractive index as the base, need not be diffused. As shown a cellulose acetate-propionate base 46 provided with an emulsion layer 47 is coated with a subbing 48 of cellulose nitrate having the same index of refraction and a coating of ureaformaldehyde resin 49 is diffused into the subbing by the use of a common solvent e.g. 20 per cent acetone, 60 per cent methanol and 20 per cent ethylene dichloride or equal parts of acetone and ethylene dichloride. A further coating of ureaformaldehyde resin 50 in a chlorinated hydrocarbon is applied, followed by a top coa'ing of cellulose caproate 51 one quarter wave-length thick. Other combinations described are a cellulose acetate base, a subbing of alkyl-toluene-psulnhonamide-formaldehyde resin, a high refractive index diffused layer of polystyrene and an overcoating of cellulose caproate or ethyl cellulose ; and a flint glass body into which is diffused a glass of high refractive index by heating in contact for some time, with an upper coating of low refractive index.

Title: Improvements in or relating to methods and apparatus for measuring the power factor of an electrical device
IPC: G01R27/26
Filed: 1940-01-11
Abstract: 537,978. Power-factor measurements. REYROLLE & CO., Ltd., A., and LIVINGSTONE, E. A. Jan. 11, 1940, No. 627. [Class 37] The power-factor of a device such as a hightension bushing insulator is measured by passing through the circuit including the device a resultant alternating current having a component in phase and a component in quadrature with the potential difference across the device, eliminating one of these components in a part of the circuit, and measuring the remaining component and the total resultant current. As shown in Fig. 1, one terminal of the condenser A to be tested is connected to the high tension end B1 of the secondary winding B of a transformer. This winding has a tapping B2 to which the other terminal of the condenser is connected through two ammeters C, D, in series. The low tension end B3, the voltage of which is proportional to that of the high tension end but of opposite phase, is connected through a variable low-loss condenser E to the junction between the ammeters.. The condenser E is varied until the current through the meter D is a minimum, this current then being the component of the current passing through the condenser A in phase with the applied voltage. The ratio of the reading of the ammeter D to that of the ammeter C, i.e. the ratio of the in-phase component to the total current represents the power factor of the condenser. To compensate for stray capacities and leakages to earth a variable resistance may be connected in parallel with the condenser E. With the condenser A disconnected the condenser E and the resistance are varied until the current through the ammeter D is zero. The tapping B2 is then at earth potential and the current through the compensating resistance is equal to any leakage current, so that this does not flow through the ammeter D. The condenser A is then connected and the powerfactor measured by varying the condenser E without disturbing the adjustment of the resistance. The ammeter D may be connected to a tertiary winding instead of the tapping B2. In a modification, Fig. 3, the low-loss variable condenser G is shunted bv a variable resistance H in series with the ammeter D, which measures the in-phase component. A galvanometer J is connected as shown and the condenser G and resistance H are adjusted until this galvanometer shows no deflection. The potential across the condenser A is then the same as that across the circuit H G D and its power-factor is the ratio between the reading of the ammeters D, C. The balancing current may be obtained through an inductance fed from a supply in phase with that supplying the condenser under test. For measuring a lagging power-factor a balancing current may be supplied through a condenser fed from a supply in phase with that supplying the device under test, or through an inductance from a point of opposite phase.
