Inventor: CONNELL MAURICE WINSLOW
IPC: H01R13/59
Filed: 1962-06-15
Abstract: 956,415. Cable glands. CONAX CORPORATION. June 15, 1962, No. 23090/62. Heading H2E. In a cable gland for metalsheathed cables the gland body 18 and a closure member 21 are drawn together to wedge a constrictable ferrule 25 on to the cable sheath 12 so that knurling on the ferrule 25 engages the conical surface 16 and prevents relative rotation therebetween. The cable conductors 10 protruding from the insulation 11 enter sockets 32 housed in a resilient dielectric block 34 which abuts the end of the cable insulation when the gland parts are drawn together to seal the connection against ingress of moisture. The outer surface of lands 26 on the ferrule 25 may be knurled or ridged (Fig. 4, not shown) to resist rotation when the gland parts are drawn together, e.g. by screwing.

Title: Improvements in optical sighting devices for light anti-aircraft guns
IPC: G02B27/32
Filed: 1965-05-31
Abstract: 1,113,212. Gun sights. BREVETS AEROMECANIQUES S.A. 31 May, 1965 [15 June, 1964], No. 23133/65. Heading F3C. [Also in Division G2] A sighting device for an anti-aircraft gun, having a barrel pivotable about a horizontal axis mounted on a platform rotatable about a vertical axis with respect to a fixed base, comprises an eyepiece 4 and a window 5 both fixed with respect to the platform, an optical system coupled with the gun barrel so as to direct into the eyepiece the light beam parallel to the barrel which passes through the window 5, regardless of the inclination of the barrel, and a transparent plate 6 carrying a horizontal reference line 10 and displaceable by an amount directly proportional to the angular movement of the barrel so that the image of the target may be made to coincide with the reference mark. The plate 6 is coupled to one end of the lever 12 which is pivotable about a spindle 13. By adjustment of a handle 29 the spindle 13 is movable along a slot 26 in the lever 12 so as to vary the degree of movement of the plate 6 with rotation of the gun barrel. Rotation of the gun barrel then rotates a spindle 8 carrying a mirror 7 and through a gear train rotates a cam 11 against the edge of which the other end of the lever 12 is urged. Thus the cam 11 causes the lever 12 to turn about the spindle 13 and move the plate 6 until the image of the target coincides with the reference line 10. A fixed transparent plate having a plurality of lines which intersect on the axis of the eyepiece 4 is viewed together with the movable plate and permits the gunner to take into account estimated vertical and horizontal components of the target's flight.

Title: Improvements in or relating to the repair of high tension insulated electric cables
Inventor: COX HENRY NORMAN
IPC: H02G15/10
Filed: 1950-09-22
Abstract: 694,508. Cable joints. BRITISH INSULATED CALLENDER'S CABLES, Ltd. Sept. 21, 1951 [Sept. 22, 1950], No. 23306/50. Class 38 (i). A method of repairing a localised fault in a high tension cable having a lapped conductor dielectric comprises cutting out sufficient cable to ensire that the ends of the cut feeder are free of faulty dielectric, preparing each cable end as if to make a normal straight through joint and jointing the end of the core conductor of one cable end through an inserted length of unscreened insulated conductor to the core conductor of the other cable end, separately insulating the two longitudinally spaced joints, and enclosing them in a common casing. This method is simpler and requires less materials than the usual one of cutting out a few yards of the cable, making two straight through joints, and enclosing them in separate casings. Fig. 1 shows the left-hand half of a repair joint according to the invention as applied to a threecore 33 kv. solid type impregnated paper insulated cable. The damaged portion is cut out to leave the two cable lengths about 1 foot apart and the lead sheath 2 out back for about 20 inches, the cores 3 being spread out and a poultice 4 applied to seal the inter-core spaces. A lead stress cone 5 is fitted on each core 3 and the core screen 6 terminated thereat. The ends of the core conductors 7 are bared for some two inches and each is connected by soldered joints through a ferrule 11 to the bared end 10 of an inserted unscreened insulated conductor 8, the other end of which is similarly connected to the corresponding core conductor of the other cable end, Fig. 1A (not shown). The joints are wrapped with tapes 12, 13 and insulating paper tubes 14, 15, previously positioned on the inserted conductors 8, are slid thereover. The tubes 14, 15 are bound to pairs of spreaders 16 by tapes 17, the spreaders being supported in a pair of insulated yokes 18 prevented from angular movement by a bar 19, Fig. 2, carried by a spigot ring 20. The joint casing 21 comprises two similar end parts 23 and an intermediate part 22, which are connected to one another and to the spigot rings 20 by wiped metal joints 25. The end parts 23 are jointed through lead sleeves 26 and wiped joints 27 to the cable sheaths 2. The cut-back armouring wires 28 are secured by clamps 29 connected by bonding strips 30, the stress cones 5 being connected to the corresponding sheath 2 by wire 105. The casing 21 which is filled with compound is inserted in a concrete box 31 also compound filled. The inserted conductors 8 may comprise scrap lengths of cable cores or insulated copper rods, and the latter may be formed with sockets to receive the cable conductors.

Title: Improvements in or relating to pit props
IPC: E21D15/44
Filed: 1950-09-25
Abstract: 716,022. Pit props. GREBE, K. Sept. 25, 1950 [Oct. 1, 1949; April 25, 1950], No. 23440/50. Class 20 (2) A fluid pressure pit prop comprises at least two relatively movable sections, one of which forms a piston in a second forming a pressure chamber and elastic buffer means associated with the pressure chamber and contained in a third section (which may also be relatively movable) and adapted to take up excessive pressure on overloading of the prop, an overload valve being opened automatically during compression of the buffer and returning to its closed position when the fluid pressure has dropped sufficiently to permit the buffer to re-expand. As shown in Fig. 1 the prop comprises three relatively movable sections 3, 1, 5, section 1 forming the pressure chamber 2 and section 5 containing an elastic buffer 6 comprising. an inflatable container abutting against the closed bottom of section 1. A duct 13 with a manually operated valve 15 and a repulsion type valve 14 supp:ies high pressure oil to the chamber 2, the discharge duct 20 being provided with a valve 21 having an extension rod 23 so arranged that on compression of the buffer 6 owing to overload, the rod 23 abuts against the upper rim of the section 5 and the valve 21 opens accordingly to release the oil and reduce pressure in the chamber 2 whereupon the buffer 6 expands and the valve 21 closes. As shown in Figs. 4, 5, the section 1 is screw-threaded in the section 5 and the buffer 6 located between bottom plate and an annular collar 9a is provided with a piston head 35. Alternatively the head 35 may be independent of the buffer 6. The section 1 is bridged at its lower end by a fixed plate 40 provided with holes 39. A supply and discharge duct 41 in the head 35 is controlled bv a spring-loaded valve 21 suspended from the plate 40 so that upon compression of the buffer 6, the valve 21 is separated from the head 35. The valve 21 may be manually controlled by an eccentric 43 operated from outside and which contacts an extension rod 44 of the valve. The duct 41 is connected to supply and discharge lines 32, 33 by a spring-loaded two-way valve 47 which is normally open to the discharge pipe 33. Depression of hand lever 49 closes the valve to the discharge line 33 and opens it to the supp'y line 32 whereupon the valve 21 is opened and the pressure medium enters the chamber 2 through the openings 39 and presses the piston 3 against the roof. On overloading of the prop, the medium is pressed from the chamber 2 against the head 35 which is pressed downwardly whereupon the valve 21 which was previously closed is separated from the head 35. The medium is therefore able to flow from the chamber 2 through the duct 41 and valve 47 which is now open to discharge line 33. On release of pressure the buffer 6 expands and the valve 21 is closed. The buffer 6 may alternatively consist of elastic resin which will expand to its normal volume upon pressure release.
