Patent GB-1238481-A (GB)
IPC: F16L3/20
Filed: 1968-01-16
Abstract: 1,238,481. Pipe-supporting spring units. BRITISH INDUSTRIAL ENG. CO. (STAFFS) Ltd. 8 Jan., 1969 [16 Jan., 1968], No. 2305/68. Heading F2S. A constant tension pipe support unit of the spring-and-lever type, Fig. 1, is characterized by the form of pivotal connection between the lever 17 and the hanger 33 to which, in use, the supported pipe is attached. This pivotal connection comprises a pin 35 from which the hanger depends and a pair of apertured members.37 carried by the lever. As shown in Fig. 3, the radius of curvature of the pin 35 is much less than that of the bearing surfaces 36 of the members 37, so that the pin is in substantially line contact with these surfaces and can roll around them when the lever 17 turns, the line of contact C thus varying in distance from the lever's fixed pivot 40 as the lever turns about that pivot. If, as is envisaged, the pipe to which the hanger 33 is attached (e.g. by a link, not shown, fitted to the turnbuckle 32) is restrained against horizontal displacement, vertically downward movement of the pipe will cause the hanger to tilt from its initially vertical orientation as shown to an oblique orientation, thereby causing the line of contact C between the pin 35 and surfaces 36 to move with respect to the latter. The specification demonstrates by means of a diagram (Fig. 5, not shown) and a table of calculated force-displacement values that a pipe secured against horizontal displacement and suspended for vertical movement by a spring-and-lever support embodying the above-described pivot means 35, 36 is acted on by a more nearly constant supporting force than such a pipe suspended from conventional spring-and-lever means. In Fig. 1, the angles A and B are respectively 57 and 60 degrees and the angle D is 23 degrees in an initial position (as shown) of the lever in which the hanger 33 is vertical. The abovementioned table indicates that D can vary from 20 degrees above to 40 degrees below the horizontal E without causing departure of the force exerted by the unit from its assigned constant value. The unit may incorporate a force adjusting means to compensate for the additional load when the supported pipe is filled with cleaning liquid as described in Specification 1,208,132.

Abstract: 1,239,133. Moulding gloves. BAXTER LABORATORIES Inc. 16 May, 1969 [31 May, 1968], No. 24959/69. Heading B5A. [Also in Divisions B2 and C3] A plastics glove is moulded with one rough and one smooth surface by dip coating a mandrel having finger portions with a PVC plastisol containing, as 0À005 to 0À05% of the combined weight of the resin and plasticizer ingredients, a blowing agent which decomposes at a temperature at or above the fusion temperature of the plastisol when the coating is heated at atmospheric pressure to cure the PVC and to produce raised blisters 30 on the free surface of the coating 28, the blisters 30 and pores within the coating being mainly spaced by a distance greater than the diameters thereof. The blistered layer is dip coated either directly on to a mandrel 10, or onto the mandrel previously provided with a dip coating of plastisol not containing a blowing agent, the mandrel being inverted after each coating within the heating chamber of an oven 18, separated from a gas burner chamber thereof by a heat conductive wall 22, whereby each coating is cured e.g. at 400‹ F. for 5 mins. The mandrel is permitted to cool to 250‹ F. before the second coating is applied thereto. In the example given, the plastisol comprises stated proportions of dioctyl phthalate, resin, petroleum hydrocarbon, organic cadmium stabilizer, and 4,4<SP>1</SP>-oxybis-benzene sulfonyl hydrazide blowing agent as 0À01% of the weight of plasticizer and resin. Other suitable blowing agents are specified.

Complex C may be incorporated with the monomers or prepolymers during polymerization to P or by pressing into the melt during spinning. C may be applied to chips of polyamide P which are then melted and spun into filaments or converted to solid articles. The P chips may be tumbled, e.g. with a solution of C in a volatile solvent, e.g. water or alcohol or with a dispersion formed by grinding C with water and a finely-dispersed polyamide. The P chips may be dyed in a bath containing an aqueous solution or dispersion of C, e.g. under superatmospheric pressure and at 130 C., the dispersion may be stabilized with a dispersant. Acetic or formic acid, or ammonium or sodium acetate or primary sodium phosphate may be added to the bath to increase rate of absorption of complex C. Dye bath treatment may be performed on chips of polyamide P in which a pigment has been incorporated during polymerization. 1-2 C in 4-250 parts water may be used per 100 parts P. P may be nylon 6 or 6,6. Articles include injection moulded zipp fasteners and telephone receivers.

Abstract: 1,267,208. Ultrasonic probes; ultrasonic inspection devices. SHURTHONICS CORP. 25. Sept., 1969 [26 Sept., 1968], No. 47131/69. Headings H4D and H4J. An ultrasonic probe, e.g. for testing adhesive bonds between metal sheets, has a generally cylindrical transducer element loosely retained by guides to permit limited radial and axial movement of the element. The guides and element remain in electrical contact during such movement through a conductive layer on the element. Friction is insufficient to damage the conductive layer. A barium titanate disc 16 (Fig. 5) has conductive layers 18, 20 on its opposite faces. The front layer 20 is continuous with conductive coatings 21 in three grooves 22 (Fig. 2). The disc 16 is held by a cap 24 in a socket 14 in the head 12a of a handle 12. Cap 24 has an inwardly extending rib which snaps into a groove 12b in the head 12a. An inwardly extending flange 27 on the cap 24 has three guides 27a which fit loosely into the grooves 22 to permit limited axial and radial movement of disc 16. To energize the probe, a voltage is applied to the inner pin 38 of a coaxial connector 40 and is transmitted through a conductor 36 and pin 34 to the layer 18. The voltage is applied across the disc 16, the circuit being completed by layer 20, the coatings 21, the guides 27a, the cap 24, the handle 12 and the outer sleeve 44 of the coaxial connector 40. In use the probe is hand held and disc 12 is placed in contact with the work surface. Coupling fluid may be used. The disc 16 may be canted and is retractable against a spring 46 insulated from the remainder by insulating bushings 32, 34. An alternative probe (Figs. 8, 9, not shown) is similar but the snap-on cap is replaced by a retaining plate (64) held by screws (65) to the probe head. A multiple probe assembly (Figs. 10, 11) has conductive rear and front panels 79, 81 joined by conductive side walls 80. Intermediate panels 82, 83 are of insulating material. The front panel 81 has nine holes 84 in each of which is inserted a transducer element 85 similar to the disc 16 of Fig. 1. Three grooves 85a in each element 85 have conductive coatings and are engaged by individual rigid guides 88 adjustably secured by screws 85 to the front panel 81. A spring 87 urges a pin 86 into contact with the rear coating on the element 85. The rear portion of each pin 86 is connected to a power source (not shown) and the rear panel 79 is earthed. Each element 85 has limited adjustment so that the assembly may accomodate a non-planar test surface. In a modification (Fig. 13), for each transducer element 85, a conductor tube 92 extends through the front panel 81 and has guides 92b which engage the grooves 85a. A tubular plug 95 of insulating material limits rearward movement of element 85. By use of the tubes 92 the assembly accommodates test surfaces which are considerably curved.
