Title: Method of measuring the outside circumference of bearing half-shells
IPC: G01B5/02
Filed: 1976-03-16
Abstract: 1488786 Measuring bearing shells MIBA GLEITLAGER AG 16 March 1976 [26 March 1975] 10429/76 Heading G1M It is known to insert a solid half-cylinder master bearing in a recessed gauge block and measure the distance its lip extends above the block and to compare this distance with the similar distance a bearing half shell to be checked extends above the block when substituted for the solid half. In the present method the solid half-cylinder is replaced by a hollow half-cylinder master 2 as in Fig. 2 and having the same elastic properties as the half shell to be tested. The hollow master half may be compared for circumferential dimension with a solid master half by placing each half successively on a block 10, Fig. 3 and wrapping a tape 11 around it, the circumferences or the difference in circumferences being read from a dial gauge 13 having its plunger attached to the tape and loaded by a weight 14.

Filed: 1923-04-17
Abstract: 211,371. Imray, O. Y., (Aquazone Corporation). April 17,1923. Air and gases, treating with liquids. -Apparatus for the liquid treatment of gases under pressure comprises a washing-chamber and a treating- chamber connected by a valved passage which opens into a gas-distributor and has a branch leading to the upper part of the treating-chamber. Gas is forced by the pump 19 by way of pipe 18 to the washing-chamber 15 and thence to the gas-distributor 12 in the treating-chamber 10, the valve 35 in the branch 33 being normally closed. The treating-chamber is filled with liquid through the pipes 25, 26, the valve 29 being normally closed. A filter 27 may be inserted in the pipe 25. Gas is passed into the treating-chamber until any desired pressure has been attained, after which the valve 40 is opened to permit the continuous escape of surplus gas. A safety-valve may replace the valve 40. The liquid is discharged through pipe 26 by the pressure of the gas, the valves 35, 29 being open and the valves 32, 28 shut. Specification 185,659, [Class 14 (i), Aerating liquids &c.], is referred to.

Filed: 1937-04-14
Abstract: 489,743. Valve amplifying circuits. STANDARD TELEPHONES & CABLES, Ltd. April 14, 1937, No. 10617. Convention date, April 18, 1936. [Class 40 (v)] The depth of modulation on a carrier wave is varied at musical or higher frequencies, according to a predetermined law, under the control of the modulated wave. A high-frequency amplifier LA, Fig. 1, of the variable gain type has an input circuit CA which also feeds the input terminals BE of an auxiliary detector DA. The modulation frequency output from terminals BS is applied in series with the bias arrangement Z, C, and depending upon the relative phase, increases or decreases the effective depth of modulation in the output DU of LA. Modifications are shown in which the invention is applied to valves in push-pull and also arrangements in which the input to the auxiliary detector is taken from the input to amplifiers preceding, or the output from amplifiers following, the controlled valve. In another modification, Fig. 8 (not shown), modulation-frequency voltages derived from an amplifier following a reacting detector valve are applied as bias to the detector. In Fig. 7, a frequency changer LCF and local oscillator OSCB which feed an intermediate frequency amplifier AMF, detector D and low-frequency amplifier ABF have low-frequency voltages fed back over the attenuator or phase control network FAD to the transformer T to modulate the local oscillator. Arrangements are also described in which the gain controlling voltages are applied to other electrodes such as the suppressor grids of pentodes ; and in all cases filters may be employed to confine the increased or decreased modulation to a portion of the frequency band.

Abstract: The invention comprises partial esters of fatty acids having 12-22 C atoms with polyether polyols made by condensing one mole of sucrose with 10-30 moles of an alkylene oxide having 2-4 C atoms, no more than three-eights of the hydroxyl groups of the polyol being esterified. The esters may be made by esterifying the acid with the polyol but are preferably made by treating the polyol, at below 350 DEG C., and above 100 DEG C., with a lower alkyl ester of a fatty acid of 12-22 C atoms in an amount of 0.5 to 3, especially 1-3, moles of ester per mole of sucrose.  The term "lower alkyl" refers to the alkyl groups of those alcohols which are sufficiently volatile to be evolved during the inter-esterification.  Indicated acids include lauric, stearic, oleic and ricinoleic acids and branched chain acids and mixtures of acids obtained from natural glyceride fats and oils e.g. cottonseed, coconut, soya and lard oils.  Ethylene, propylene and 1,2-butylene oxides are specified alkylene oxides.  The sucrose polyether polyols are preferably prepared at 70-270 DEG F., under pressure of up to 200 p.s.i. in the presence of 5-30% by weight of water, based on the sucrose, and sodium hydroxide.  The products are surfactants which may be dispersed in water and, in some instances, in cold water. Examples are provided of the preparation of the esters by inter-esterification methods.

Abstract: 579,612. Pressure gauges. B. & R. PATENTS, Ltd., and BIRCH, G. C. R. June 5, 1944, No. 10814. [Classes 106 (ii) and 106 (iv)] A differential pressure gauge comprises two pressure-responsive elements, each mounted on an abutment, the movable parts of the elements being loaded by a spring finger or rod anchored to the base, the indicating mechanism being actuated in accordance with the flexure of the spring rod in one direction or the other. As shown, two bellows E, E<1> mounted on abutments E<2>, have their movable ends connected by an adjustable coupling F, Fig. 3, embracing a spring rod J clamped near one end by a screw J<2> to the casing. The free end J<3> of the rod acts on a spring-pressed lever K pivoted at K<1>, the lever K actuating a quadrant and pinion indicating mechanism. The effective length of the rod J and therefore the magnification of the indicating mechanism can be adjusted when the screw J<2> is released. Since the resistance to deflection of the spring rod increases more rapidly than the deflection, the gauge is sensitive to light differences of pressure, but can measure large differences. The connection of at least one of the bellows to the tube G <5> supplying the pressure is made adjustable transversely (Fig. 4, not shown). Each bellows may have an overload stop, Fig. 5, comprising an adjustable hollow distance piece P cooperating with a stop P<1>. The bellows may be replaced by Bourdon tubes.

Filed: 1946-04-09
Abstract: 613,544. Aerials. WESTERN ELECTRIC CO., Inc. April 9, 1946, No. 10895. Convention date, April 23, 1945. [Class 40 (vii)] An aerial system comprising a main reflector facing an energized primary aerial element formed by a wave-guide aperture is characterised in that a substantially flat auxiliary reflector is positioned facing the primary element and in alignment with the main reflector and the primary element, the dimensions of the two reflectors being such that the main reflector is substantially flat adjacent the periphery of the auxiliary reflector and the electrical lengths of the paths between the primary element and the two reflectors being different so that waves reflected by the two reflectors cancel at the primary element and the formation of standing waves in the wave-guides is thereby prevented over a relatively wide band of frequencies. The Figure shows the invention applied to a cylindrical parabolic reflector 1 energized by a wave-guide aperture 9, an auxiliary flat reflector strip 10 being mounted at the apex of the reflector symmetrically with respect to the axial plane. 4. In Fig. 4 (not shown), the cylindrical parabolic reflector is fitted with end plates to form a cheese reflector, the auxiliary reflector being as described above. In another embodiment, Fig. 11 (not shown), two separate auxiliary reflecting strips are mounted symmetrically on each side of the axial plane. When applied to paraboloidal reflectors, the auxiliary reflector may comprise a disc or annular ring coaxial with the reflector axis. A theoretical discussion is given of the method of determining the dimensions of the auxiliary reflector as a function of the mean wavelength and the focal length of the reflector and satisfactory results have been obtained with reflector strips .5#-1.33# in width and #/9-#/5 in thickness. In another embodiment, an aperture is provided in the main reflector and the auxiliary reflector is then positioned behind the main reflector. Specification 581,457 is referred to. According to the Specification as open to inspection under Sect. 91, the reflecting surface of the auxiliary reflector may be parabolic. This subject-matter does not appear in the Specification as accepted.
