Abstract: 1,019,950. Electric blasting detonators. SOC. DE PROSPECTION ELECTRIQUE SCHLUMBERGER. Oct. 19, 1962 [Nov. 24, 1961], No. 39672/62. Heading F3A. An electric detonator, from which the usual primary charge is omitted as in Specification 884,041, comprises a steel tube 10 housing a secondary explosive, e.g. penthrite, and having an internal diameter of at least 8 mm. for a length of at least 37 mm., the explosive being initiated by an igniter housed in the detonator and comprising a resistance wire in contact with an inflammable powder. The tube is of reduced external diameter at each end, one end being closed by a metal diaphragm 14 and engaged in a metal adapter 24 while the other end is fitted with a ferrule 46 and closed by a conical member 18. The ferrule 46 has a transverse bore receiving a quick-match 52, which is secured by a screw 48. The adapter 24 has an axial passage in which is inserted a needle-shaped igniter 32 extending through the diaphragm 14 into the explosive 42. The igniter is filled with black powder in which is embedded a resistance wire 34. One end of the wire is connected to a conductor 36 passing through an insulating plug 28 and the other end of the wire 34 is connected to the conductive wall of the needle and thence through diaphragm 14 and adapter 24 to a conductor 37 for the return circuit. In a modification both conductors are passed through an insulating plug and through glass beads before entering an incendiary charge, which when ignited by passage of a current through the bridge-wire connecting the conductors fires the secondary explosive. In this case the quick match is held to the detonator by an elastic sleeve fitted over an extension of the steel tube. The explosive may be hexogen or tetryl and the tube 10 is 3 mm. thick. The detonator is said to be insensitive to static charges, spurious currents and hot gases under pressure. Reference has been directed by the Comptroller to Specification 884,041.

A photographic view-finder of the Albada type is combined with a telescope to form a range-view-finder, the telescope forming a real image of the distant object at an inclined mirror disposed in the focal plane of the part transparent concave mirror of the Albada finder so as to re-direct the range-finder beam along the optical axis into the concave mirror to form a virtual image at infinity both of the viewed object and of the inclined mirror. In the form shown in Fig. 1, the Albada finder comprises a plano-concave lens 1 cemented to a glass block 3 which is cemented to a lens 4 consisting of two parts which are cemented together at an inclined surface, coated at 8 to form an inclined mirror. The lens 4 carries a reflecting frame 5 and this frame and the mirror 8 are disposed in the focal plane of a part transparent mirror 2 formed at the cemented surface between lens 1 and block 3. A real image of the distant object is formed by a lens 10 at the mirror 8, this lens 10 and the mirror 2 respectively forming the objective and eyepiece of a telescope. Mirror 8 redirects the range-finder beam 8 towards the camera mirror 2 so that an image of the object is formed approximately at infinity and is superposed on the image of the frame 5. Range-finding is effected by displacing lens 10 which is mounted on a carrier 11, pivoted at 14. In a further form, the image is formed at the inclined mirror by the objective and erector of a terrestial telescope having the concave mirror 2 as its eyepiece. Range finding is effected by a rocking mirror in the light path between the objective and the erector. In this second embodiment the inclined mirror is formed between the abutting bevelled surfaces of two plain parallel plates which are interposed between the glass block 3 and the frame carrying lens 4.

[Also in Division F1] In a die-casting machine an injection plunger 11 is moved by an hydraulically-actuated piston 129 that moves slowly at first and is then speeded up when the die cavity 15 is partially filled. The piston is moved initially by oil passing through a valve 134, and around a by-pass 147 containing an adjustable restrictor 148. By means of a lost-motion connection 144, 145, 146 the piston 129, after an initial movement, moves a valve member 142 to allow unrestricted flow of oil to accelerate the piston. At the end of the travel of the piston 129 a pressure rise in the oil above the piston is used to open a spring-closed port 153 and move a spool 150 to re-direct the pressure oil to drive down a further piston 135 so that its rod 137 strikes an extension 141 on piston 129 to increase the injection pressure to ensure a " sharp " casting.

[Also in Group XXXIV] A process for the manufacture of bearing races for needle bearings or other bearings embodying elongated rolling members, wherein said races possess a convex raceway and a mounting surface having a rectilinear generatrix is characterized in that the generatrix of the radial cross section of the surface of the blank which is intended to form the convex raceway is initially made rectilinear and the generatrix of the opposite surface, which is intended to fit the race on the bearing support, is initially made convex, and the blank is then cold-deformed to invert the shapes of said generatrices. In an embodiment a cylindrical blank is arched, Fig. 2, and the outer surface 6 is cylindrically machined and hardened, Fig. 4. The blank is then forced on to a mandrel 7 so that the blank deforms to produce a hardened convex raceway 9, Fig. 5. In another embodiment the machined blank, Fig. 3, is subjected to profile reversal and hardened on its inner surface 3, Fig. 7, and then forced into a bore 15 in a housing 13 to form a convex race 16, Fig. 8. In another embodiment a cupped blank of cross section 20, Fig. 11, is mounted on a mandrel 23 having a concave portion 24 the blank being pressed on to the mandrel by a tubular die 25 to impart the desired variable thickness of cross-section to the blank. Alternatively the blank 22, Fig. 14, is shaped by a convex profiled roller 31 whilst mounted on a cylindrical mandrel 30. The cupped blank is then cut along the two planes I and II and subjected to the profile reversal operation to form the bearing race. Specification 713,765 is referred to.

Abstract: 1389656 Transferring containers between conveyers SOVEX Ltd 24 Aug 1973 40219/73 Heading B8A Containers 1 fed to or discharged from a vertical endless conveyer by means of a pivotal loading device 6 (Fig. 1) or a pivotal unloading device 14 (Fig. 3), as described in Specifications 1,206,271- and 1,315,093, are loaded on to the loading device 6 or are discharged from the unloading device 14 in a lateral direction with respect to the direction of movement of the loading device or the unloading device. In Fig. 1, the container 1 may be fed on to the loading device 6 from either side of the conveyer by endless belt conveyers 8a, or 9a. The end rollers 10 or 11 of these conveyers serve to position the container correctly relative to the device 6. A switch 12, operated by the container 1, causes the device 6 to pivot from its normal upright position (Fig. 2a, not shown), to an inclined position (Fig. 2b), in which V-shaped side flanges 4 are in a position to be taken up by projecting carrier rods 7 carried by chains 5a, 5b, of the main conveyer. In a discharge arrangement (Fig. 4a), a roller conveyer section 17 is carried by the unloading device 13. When the latter is in position (broken lines, Fig. 3) to receive a container 1 from the conveyer, the container is deflected by arms 14 of the device 13 on to the rollers of the conveyer 17. When the device 13, either by gravity under the weight of the container acting about a pivot 15, or in some other manner, tilts back to the full line position, one end of the conveyer 17 is engaged by a stop 20. The conveyer 17 is therefore held in an inclined position and the container rolls away on the conveyer 17 to a discharge conveyer. In a modification of this arrangement (Fig. 5, not shown) either end of the roller conveyer is automatically raised by a jack device (26a) or (26b). In a further modification (Fig. 7b) an abutment 30 of the unloading device on to which the container is received, deposits the latter on to the belts 31a, 31b of an endless discharge conveyer for discharge in either direction to conveyer belts (33), (34), (Fig. 6b, not shown).
