Abstract: 1481907 Slip clutches EMERSON ELECTRIC CO 30 Oct 1975 [12 Dec 1974] 44982/75 Heading F2C In an overload release clutch wherein a clutch roller 60 carried by a two arm lever 50 pivoted in a housing 30 is biased by a spring 70 into engagement with a recess 45 in a disc 20 fast with a hub 10, the housing 30 provides a sealed lubricant retaining enclosure for the clutch and antifriction bearings 55, (58), 48 are provided between the roller 60 and a pin 54 fast with the lever 50, between a pivot pin 57 of the lever 50 and the housing 30 and between the housing 30 and hub 10 respectively. The roller pin 54 is secured to arms 52, 53 of a yoke 51 forming one arm of the two armed lever 50. A screw 39 adjusts the compression of the spring 70 and thus the torque at which the clutch disengages. The torque at which the clutch disengages may be different for opposite directions of rotation. On overload relative rotation between the hub and housing causes segments 130 radially slidably secured to the housing and biased radially inward by a spring 150 to be moved radially out by cams 123 on a ring 121 fast with the hub. The outward movement of the segments 130 actuate a switch 160 to signal slip.

Title: Manufacture of alcohols from esters
Inventor: KOEBER ADOLF
IPC: C07C29/74
Filed: 1962-12-07
Abstract: Alcohols having at least 8 carbon atoms are prepared from esters thereof with fatty acids having at least 8 carbon atoms by saponifying the ester, or mixture of esters, and extracting the resultant alcohol with a solvent of low polarity in the presence of an aqueous hydrotrope solution.  The saponification is performed in the normal manner and the hydrotrope is preferably added to the reaction mixture prior to saponification.  The solvents of low polarity are those solvents which are substantially insoluble in hydrotrope solutions, for example solvents of polarity between that of diethyl ether and that of the paraffin hydrocarbons. Specified hydrotropes include the alkali metal and alkaline earth metal salts of C1-C4-alkyl benzene sulphonic acids, the alkali metal salts of benzene, xylene and toluene sulphonic acids and urea.  In a continuous process the esters are fed into the reaction vessel together with the aqueous hydrotrope and alkali, the resulting mixture is passed into a separator to which solvent is continuously added, the solvent layer is removed and distilled to recover the alcohol and the solvent, and the aqueous layer is removed and, if desired, the hydrotrope and fatty acid recovered therefrom. Specification 1,002,974 is referred to.

Patent GB-465205-A (GB)
Abstract: 465,205. Power meters. TRIGGS, W. W. (Doble Engineering Co.) Oct. 1, 1935, No. 27109. [Class 37] In a wattmeter the effect of capacitance in or associated with the current circuit, produced by the inductive effect of the voltage circuit Lp on the current circuit when the former is energized, is nullified or neutralized by electrical or magnetic conducting means arranged to react with the electric or magnetic fields associated with the current coil Lc so as to vary its associated magnetic field. Such means may consist of masses or vanes v, v1 adjustably arranged near the current coil which may be of magnetic material or merely of conductive material. The casing N may form a magnetic shield and the current coil may have a high resistance. Adjustment is effected for internal capacity effects by energizing the voltage circuit with the current circuit open and varying the position of the vanes v, v1 until true zero reading is obtained. Where external capacity is present, an equivalent capacity is connected across the current coil during adjustment. The instrument may be used in a cable testing system as set forth in U.S.A. Specification 1,945,263 in which the current coil of the wattmeter is connected between the guard shield of a cable, supplying test current to insulation to be tested, and earth. The supply cable consists of a conductor connected to one terminal of a supply transformer, an inner or guard shield connected to the other terminal of the transformer and an outer grounded shield.

Abstract: 1,272,510. Vortex device. HONEYWELL Inc. Oct. 6, 1970 [Oct.13, 1969], No.47404/70. Heading G3H. [Also in Division G1] A vortex rate sensor 11, designed to produce a fluid-pressure signal corresponding to the angular motion of the body of the sensor, comprises two concentric chambers 12, 13 which are separated by a porous member 14, the porous member allowing only radial flow into chamber 12 from chamber 13, the latter chamber being connected to a supply 17. The inner chamber 12 has a centrally located outlet leading to a passage 18 and disposed diametrically across the outlet is a blade element (20) Fig. 2 (not shown) from the sides of which extend two pressure signal conduits 22. An angularly adjustable blade-like member 25 projects into the inner chamber and is designed to compensate for any manufacturing deviations resulting in a pressure differential between the signal conduits 22 even when the sensor body 11 is stationary. The blade member is adjusted until its plane makes a predetermined angle (#) Fig. 27 (not shown) with the radius intersecting the blade longitudinal axis 26 and so causes the fluid passing along the blade to take a non-radial path towards the central outlet thereby affecting the remaining fluid-flow in consequence of which the conduits 22 register equal pressures when the sensor is stationary. Accordingly the differential across the two conduits 22 would, with blade 25 properly set, accurately correspond to the sensor angular motion. A further, calibrating blade element 37 is provided, such element, being non-rotatably and axially displaceable within a bore 35 and being baised out of chamber 12. The blade is set at a predetermined angle relative to the radius at its longitudinal axis 36 and as such can be used for calibrating purposes once blade 25 has been set to give a zero-reading at the output ports 22 and in the absence of angular motion of the sensor 11.

Title: Improvements in or relating to sub-halide distillation process for aluminium
IPC: C22B21/00
Filed: 1962-12-17
Abstract: In the sub-halide distillation process for recovering aluminium upwardly moving gaseous aluminium trihalide contacts a downwardly-moving columnar mass of granular Al-containing alloy which is kept hotter at the top that at the bottom; aluminium monohalide is formed. The temperature may be 1000-1400 DEG  C.; the alloy may be carbothermic, produced by direct reduction of bauxite with coke; the halide may be the chloride.  In the Figure, electrode sets 25, 29, 28 each comprise 4 electrodes at 90 degrees.  The power density in the converter between 25 and 29 should be, e.g. 5-10 kw./cu. ft., and between 29 and 28 should be 1-4 kw./cu. ft., thereby maintaining the upper portion of the charge at 5-75 DEG  C. higher than the lower portion.  At least some AlCl3 passes in countercurrent with spent alloy emerging via rotating cone 19.  Alloy enters and leaves the converter continuously.  Aluminium is formed by disproportionation of the cooled AlCl gas; the Al condenses and the gaseous AlCl3 may be recycled. <PICT:0975444/C1/1>

Abstract: 1,107,359. Explosive forming. FOSTER WHEELER CORPORATION. 10 Nov., 1965 [13 April, 1965], No. 47788/65. Heading B3Q. A corrugated metal sheet is produced from a flat blank 14 by placing the blank over a number of parallel mushroom-sectioned supports 20, positioning strips 12 of explosive parallel to but intermediate the supports 20, covering the strips with a plastic sheet 36 and a trough of water 26, and detonating the explosive strips simultaneously. The corrugations are free formed between the supports 20, the resulting crosssection of the sheet being sinusoidal. In order to prevent shrinkage of the blank strips 36 of explosive are provided around the edges of the formed area of the blank to hold it down. A profiled sheet of explosive may be employed in place of the strips. The edges of the blank extend beyond the margins of the trough to prevent the overall dimensions of the blank from changing during forming. In an alternative form (Fig. 6, not shown) a panel 62 is formed over tubes 56 placed on a support 50. The non-functioning of one strip of explosive, as shown, has necessitated making a longitudinal pile of wet sand 82 enclosing primacord strips 78 and 80, the strips being detonated to form the missing corrugation.
