Title: Electric cables and a method of producing them
IPC: H01B9/02
Filed: 1975-05-02
Abstract: 1486953 Insulated cables KABEL-UND METALLWERKE GUTEHOFFNUNGSHUTTE AG 2 May 1975 [11 May 1974] 18463/75 Heading H1A A high or very high voltage electric cable has a conductor smoothing comprising a material cross-linkable without externally applied heat (preferably thermoplastic or elastomeric and cross linked by the action of moisture and an electrically conductive constituent, under insulation comprising a grafted polymer crosslinked by moisture. Premature cross-linking of the conductor smoothing is avoided by (i) delaying adding the conductive constituent (carbon black) until just before or during the operation whereby the smoothing is applied to the conductor, (ii) using coarse grains of carbon black, i.e. about 95 mÁ, (iii) using grades of carbon black like ketjenblack EC (R.T.M.). The addition of 10% of which reduces the resistivity to below 100 ohm.-cm., or (iv) adding calcium oxide since it absorbs moisture more readily than the polymer. The grafted polymer for the insulation is obtained by adding one or more cross-linking agents to the polymer in free flowing granular form. Alternatively the conductor smoothing may contain one or more peroxides which thermally decompose to cause cross-linking when the core is passed through a UHF radiation unit, the carbon black particles absorbing energy and becoming heated. As an alternative to UHF radiation, the peroxide may be decomposed by heat from the insulating layer during extrusion. In each case the insulating layer is crosslinked simply by adding water.

Title: A support bar for underground workings
IPC: E21D17/086
Filed: 1959-05-29
Abstract: 845,976. Mine-roof supports. VANWERSCH, L., VANWERSCH, A., and VANWERSCH, P. May 29, 1959 [May 30, 1958; July 25, 1958], No. 18471/59. Class 20(2) Pivot-and-wedge roof-support bars, 1, 2, preferably of tongue-and-fork form, are symmetrical about their horizontal longitudinal axes and have a single axial pivot aperture 7 at the end 1 of the first-erected bar and two alternative pivot apertures at the end 2 of the bar next to be erected, displaced to opposite sides of the axis, one (7a in other not shown) and the aperture 7 receiving a pivot 4. Axial holes 8, 8a co-operate with a wedge (not shown) driven therein to force the bar 2 against the mine-roof. The root of the fork in the end 1 is defined by a surface 21 coaxial with the aperture 7, the contour of the end 2 being so shaped as to engage the end 21a of the surface to limit clockwise rotation of the bar 2, enabling it to support the working face. The pivot 4 may be so shaped as to bear only partly on the aperture 7a so as to relieve from stress the narrow web separating the apertures 7a, 7b. In reversed assembly of the bar 2, the pivot 4 engages the apertures 7, 7b.

Title: Improvements in automatically openable, foldable umbrellas
IPC: A45B25/16
Filed: 1970-04-20
Abstract: 1,274,802. Automatic umbrellas. ALASKA UMBRELLA INDUSTRIES CO. Ltd. April 20, 1970 [Oct. 6, 1969; Oct. 7, 1969; Oct. 8, 1969], No. 18759/70. Heading A4P. An automatically openable, foldable umbrella has a stick 1 comprising large and small diameter tubes 2 and 4 respectively telescopically engaged and extensible by a spring 11, Fig.3. Upper and lower sliders 18 and 19 respectively carry struts and auxiliary struts 21 and 22, Fig. 1, respectively, the sliders are separated by a spring 25, which is in two oppositely wound parts 41 and 42, and which on expansion erects the canopy frame. The outer ends 21<SP>1</SP> of the struts 21 are pivoted to the inner ends of outer rib portions 20b, which are of circular section, by means of a mounting member (35<SP>1</SP>), Fig. 4 (not shown), and slide within "U" section inner rib portions 20a guided by a tube 35. A resilient locking member 15 has large and small detents 14 and 13 respectively which project through slots in the small diameter tube 4 to engage slots in the large diameter tube 2 and the lower slide 19 in the closed position. Large detent 14 also engages a slot 31 in a sleeve 32 of a tip cup 29 which when slid along the tube 4 against a spring 34 both depresses the large detent 14 so releasing the large diameter tube 4 and the lower slider 18, and disengages the tipsof the ribs 20 thus permitting self erection of the umbrella. Relative rotation of the component parts is prevented by a groove (3), Fig. 8 (not shown) in the small diameter tube 1 which engages a projection 39 in the tip cup 29 and a projection 38 in the large diameter tube 2. A rod 8 projecting into the groove (3) acts as a stop to limit the extension of the stick by engaging projection (10) Fig. 7 (not shown) on the large diameter tube 2. An open position detent is provided by balls 6 which are urged outwardly by leaf-spring 7. The impact of opening is absorbed by a cushioning spring 37. Alternative embodiments of the tip cup 29 are shown in Figs. 12-15 (not shown). In Figs. 14 and 15 the tips are guided into the cup by means of a tapered guide surface (40).

Abstract: 849,302. Stoves. MACKAY, J. E. June 20, 1957, No. 19464/57. Class 126. [Also in Group XIII] A room heating stove, from the front of which heat is radiated directly into the room, comprises a gas or solid fuel fired heating chamber having hollow walls 10, 11 at its sides and back, the arrangement being such that hot gases flow from the heating chamber downwardly through the hollow side walls to enter directly the hollow back wall in which they flow upwardly to a flue exit 15 at the top of the unit. Fins may extend from the inner member of a hollow wall into the space between the two wall members. The solid fuel stove unit shown is adapted to be inserted in a masonry fireplace structure A or surround which in conjunction with a partition member 27, Fig. 9, defines a space in which cold air entering through an inlet 28 is heated in flowing over the stove before passing into the room through openings in louvres 18 forming the upper part of a front closure member 17 which is spaced forwardly from the front of the stove and so is cooled by a rising current of air. The heating chamber includes a bottom grate 16 and an inclined front grate 16A admitting air to complete the combustion of the fuel. The grate 16A it is said also serves to admit a supply of combustion air should the grate 16 become blocked with ash. The side and back wall surfaces of chamber A are lined with firebricks B. A combined ash pan access panel and combustion air regulator plate 23 may, by means of a knob 23a, be adjusted towards or away from the front of the stove hence controlling the supply of combustion air to the space beneath the grate 16. Hot gases from the chamber A may be passed directly to the flue if necessary, e.g. when lighting up, by means of a bye-pass 14a, Fig. 5.
