Filed: 1976-07-20
Abstract: 1527677 Electrical connectors WESTERN ELECTRIC CO Inc 20 July 1976 [21 July 1975] 30235/76 Heading H2E In an electrical connector comprising a metal sleeve 27 with inwardly directed tangs 43 which pierce the insulation of wires pushed into the sleeve so as to effect electrical connection between them, the tangs are covered by an inner tube 60 of perforable polymer material to facilitate the insertion of the wires. As shown in Fig. 3 the metal sleeve, which may be of phosphor bronze, is surrounded by a soft brass outer sleeve 29 which in turn is surrounded by a polyolefin jacket heat shrunk in position. In one automated method of manufacture a lined inner sleeve 27 is produced by the method of Fig. 10, described in detail in Figs. 11A-11I (not shown). A metal strip is advanced through stations in which tangs 43, and ridges 71a, 71b and detents 64 are formed. Adhesive is applied by rollers to end portions 27a, 27b, the liner material is applied from a roll (being held away from the tangs 43 by the ridges and detents) and flat blanks as shown in Fig. 9 are cut. These are then bent into oval lined sleeves (Figs. 11E-11I, not shown). The outer sleeve and jacket are then applied in accordance with Fig. 23. In alternative methods for producing the lined metal blank, (a) the liner is preformed with upstanding "bubbles" extending over the area of the tangs thus making the tang-avoiding ridges unnecessary (Figs. 17A-21, not shown), (b) individual plastics blanks ("postage stamps") are cut and applied (Figs. 22A-22F, not shown). The liner may be a polymer or a heat sensitive ionomer, and may comprise polyester resin, p.v.c., polystyrene, acrylonitrile butadiene styrene (ABS), polycarbonate vinylidene chloride or vinylidene fluoride. It may be bonded to the metal strip by heat, ultrasonic adhesion or adhesive with or without heat. The final connector may comprise-instead of two sleeves-a single sleeve of malleable metal.  It is also envisaged that the plastics liner within the sleeve may be a completely closed wall tubing or a tube with a longitudinal slit.

Abstract: 1,175,150. Dental impressions. K. REDTENBACHER. 4 July, 1967 [11 July, 1966; 19 July, 1966], No. 30757/67. Heading A5R. For use in restorative orthodontics in the provision of an artificial crown for a natural tooth root, a root channel composition bearer is used in combination with an impression cap to produce a moulding of the excavation of a root channel of a tooth together with an impression of the corresponding stump of the tooth; the composition bearer is in the form of a pin, at one end of which is at least one laterally extending projection, from the side of which remote from the pin extends a peg, while the impression cap is cylindrical with one end closed by a cover, the cylindrical surface of the cap having projections. As illustrated in Fig. 1, the impression cap comprises a cylindrical jacket 1 having one end closed by a cover 2 with a laterally projecting rim 3, the cylindrical wall of the jacket having integral annular projections 4, which projections slope in roof-like manner away from the closed end of the jacket, and a palpable direction mark 5; the impression cap may be made of plastically deformable material, for example a tin or aluminium alloy or a carbon- or siliconbased plastics material. As illustrated in Fig. 2, the composition bearer comprises a pin 6 at one end of which is a circular plate projection 7 from the free surface of which extends a securing peg 8 of square cross-section and endowed with measuring marks. Annular grooves 10 are formed in the surface of the pin; alternatively, the pin may have longitudinal grooves (which may be discontinuous and of different width or depth) or circular or helical grooves or ridges. The pin, which also may have measuring marks, may be made of combustible material. Holes 11 are formed to extend through the plate projection, which may be circular or of different shape; alternatively, the plate projection may be replaced by separate segments of a circle or by securing pins which may be arranged in more than one row. When used to obtain an impression, as illustrated in Fig. 3, the composition bearer, coated with a moulding composition, is inserted into the excavation 12 of the root channel of the tooth and the impression cap, filled with a moulding composition, is placed on the tooth stump and the projecting portions of the composition bearer. The cover to the impression cap ensures that, when pressure is applied to the impression cap, moulding composition is forced from the open end of the cap in the direction of the arrow 18 into the gum recess 17 formed by the exposed part 13 of the tooth stump, the adjacent part 14 of the gum and the bead 15 of the gum which merges with the mucous membrane 16 of the mouth.

Abstract: 1279019 Photo-electric testing COMMISSARIAT A L'ENERGIE ATOMIQUE 18 June 1969 [20 June 1968] 30893/69 Heading G1A In a method and apparatus for monitoring an optical characteristic of an article values detected during each scan of the article are compared with at least two reference values. The article, a radiograph of a uranium fuel element, is mounted on a reciprocating table to reciprocate beneath a detector head carrying its own light source, mounted on a lead-screw, and the radiograph includes two lines conveying the reference values which may be equivalent to the minimum and maximum uranium content to be tolerated, the lines having been produced on the radiograph by two aluminium strips whose thickness is such that their X-ray absorption is representative of these values. The scanning mechanism may be driven by a motor, or manually by a hand wheel, and the positions of the head relative to the radiograph are recorded on a chart. The instantaneous radiograph values are detected by a photo-multiplier and the reference values are developed on a pair of auxiliary photo-cells, the photo-multiplier having an electro-magnetically controlled shutter to obstruct the light beam if it becomes excessive. The reference values are stored and the instantaneous values detected by the photo-multiplier are separately compared with them to indicate on a record whether the value is between, above, or below the reference values. The reference values may also be detected by the photomultiplier. The arrangement eliminates errors arising in the preparation of the radiograph. The detector may respond to the refractive index of the article, and may be used to detect a line, or to obtain an average value in a desired zone by counting.
