Title: Axle casings and to the process and apparatus for the manufacture of these casings
Inventor: WERNER E
IPC: B21K1/26
Filed: 1971-10-11
Abstract: 1372563 Making axle casings; forging EUMUCO AG FœR MASCHINENBAU and MASCHINENFABRIK AUGSBURG-NDRNBERG AG 11 Oct 1971 [10 Oct 1970] 47312/71 Headings B3A and B3H A rear axle casing for a motor vehicle is made from a pair of casing halves 1, Fig. 14, welded together along a transverse zone 11 and each formed of a forged blank of varying longitudinal thickness. The starting billet has a aquare or round cross-section and after heating the billet is stretched by rolling to produce a preform billet (3), Fig. 2 (not shown), of varying section. The preform billet is forged in steps to a flat-blank 6, Fig. 9, formed with lateral bulges 7 which form the differential housing in the formed casing. The forged flat blank is then bent to the shape of the casing half, Fig. 12 (not shown). The forging steps are performed so that initially only the zones 4a of the billet are forged and in the last step forging is effected only in the zones of the bulges 7. The press for forging the preform billet comprises a lower die 9, Fig. 16, with a flat or contoured surface providing three forging stations 13, 14, 15. The billet is fed by an abutment (17), Fig. 20 (not shown), on a conveyer (16) to an aligning device 18 with an opposed pair of jaws 19. A fluid operated pusher (25), Fig. 20, (not shown), feeds the billet to the die station 13 against an adjustable end stop 32. The billet is positioned laterally by a strip 35 mounted on sliding rods 37 moved by piston-cylinder units. The strip also has parallel rods 41, 48 each provided with an adjustment screw (42), (47), Figs. 18 and 19 (not shown), which abuts a fixed stop (43) to allow the billet to be correctly positioned at the stations 14, 15. The flat blank produced is ejected from the press by being lifted by an arm (58), Fig. 21 (not shown) and pushed by a roller driven rod (62). In an alternative embodiment the upper die of the press is displaced stepwise and the blank remains stationary on the bottom die during the forging steps.

Title: Means for supporting nuclear fuel
IPC: G21C3/33
Filed: 1972-10-17
Abstract: 1416333 Fuel elements BRITISH NUCLEAR FUELS Ltd 28 Sept 1973 [17 Oct 1972] 47862/72 Heading G6C A nuclear fuel assembly comprises a plurality of metal clad fuel pins (only one of which is shown in Fig. 3) retained in parallel spaced relation on a common support structure 3, each fuel pin having a fuel-containing portion la and an end-fitting portion 1b, the latter portion co-operating with the support structure in such a manner as to retain the fuel pin in position in the assembly whilst undergoing extension or contraction of length. The support structure 3 comprises a plurality of deep cross beams 4 extending chordwise across an annular member (Fig. 2, not shown) to the upper faces of which beams are secured rows of locating members in the form of spigots 6, each of which is dimensioned to enter as a push fit a socket 7 in the end-fitting position 1b of a fuel pin. Each spigot 6 comprises a stem 6a and an enlarged head 6b with a tapered surface 6c, while the entry to each socket 7 is a tapered hole 8 leading through a neck 9 to a cavity 10 of enlarged cross-section. The extremity of the socket 7 is bifuracted so that it straddles the underlying beam 4, thus preventing rotation of the fuel pin relative to the support structure. An upward pull on the fuel pin to remove it from the assembly will if large enough separate the spigot 6 and socket 7 by distortion and even fracture of these parts without breaking the fuel-containing portion la. For example, the. spigot head 6b may be pulled through the neck 9 scuffing to surfaces, the stem 6a may fracture and the parts separate leaving the head 6b in the cavity 10, or the wall of the cavity 10 may fracture adjacent the bulkhead 11 separating it from the fuel-containing portion 1a.

[Also in Division F2] In a conveyer system as described in patent Specifications 1,047,621 and 1,047,622, each trolley is provided with a braking mechanism on one or more wheels to prevent reverse movement of the trolley when it has been brought to rest by engagement with a stop or a preceding trolley. Each brake comprises a wedge 45 carried by two arms 39 pivotally mounted on the bearings 42 of wheel 15; the wedge surface 49 has an axis of curvature 49a offset from the wheel axis and has a central groove 51 to accommodate a ball 52. The lower part 48 of wedge 45 acts as a skid on track 10a. A pin 53 connecting arms 39 to wedge 45, engages in an oversize hole in a bracket on the trolley, Fig. 7 (not shown), to limit pivotal movement of the wedge. During normal forward movement of the trolley, the ball 52 rides up groove 51 and allows wheel 15 to rotate freely; however, on reversal of the trolley the ball wedges between the wheel 15 and wedge 45 and forces the lower wedge part 48 against the track to inhibit such reverse movement. Alternatively, to limit rotation of the wedge, a plate attached to the wedge, has an extension co-operating with a fixed member on the trolley, Fig. 8 (not shown).

A submersible barge comprises a plurality of flexible sheets 14, 20, 22, Figs. 2 and 6, which form a distensible envelope or container wherein cargo e.g. a liquid, can be lodged, ballasting being effected by suitable material, e.g. a slurry, coal, rock or sand, deposited in a semi-rigid tube 12 attached to the lowermost sheets 14. The sheets 20 have parallel longitudinal edges (23, 24), Fig. 3 (not shown), and oblique edges (26) at their ends, the edges of adjacent sheets being connected to one another by flexible strips or hinge pieces 32, Fig. 4, such that said container has a corrugated form with conical ends 42. The leading end or bow of the container may be separated from the remainder of the container by a flexible diaphragm 44 so that said end can be subjected to internal pressure sufficient to prevent deformation of the container when the barge is under way. Buoyancy control is effected by air-storage tubes 18 within the tube 12. The said sheets and hingepieces may be made of an epoxy-resin-bonded fibre-glass material and may be rendered integral with one another. The tube 12 may be made of fibre-glass.

Abstract: 1,124,070. Cutting by fusion. HANCOCK & CO. (ENGS.) Ltd. 15 Nov., 1966 [1 Dec., 1965], No. 51003/65. Heading B3V. [Also in Division G3] An automatic punch control apparatus for use in an oxygen jet cutting machine having a cutting burner, for making marks in a workpiece as it is being cut by the burner, comprises a marking punch in fixed relationship to the cutting burner and movable therewith, means to drive the punch into the workpiece to make a mark and electric circuitry for automatically actuating the driving means so that marks are made in the workpiece at desired points lying on a line parallel to the cut made by the burner. As shown, a conical punch 13 is caused to engage a workpiece 11 by a pneumatic actuator 12 controlled through a valve 15 operated by a solenoid 17. The actuator is positioned by a line follower, not shown, which also moves an oxygen jet cutter. The solenoid 17 is energized, through contacts KL1À2 of a relay RL1, from an alternating current supply. The relay RL1 is selectively actuated by a cyclic arrangement or a photo-electric mark sensing arrangement by changeover of a switch SW1. The cyclic arrangement comprises a transistor VT1 biased by a capacitor C1 charged through a resistor R2 and rheostat RV1. As the conduction through transistor VT1 increases the voltage across a resistance R1 causes a transistor VT2 to become more conductive so that the relay RL1 operates. The closure of contacts RL1À1 causes the capacitor C1 to discharge through a resistance R4 to release the relay after the making of a mark on the workpiece. The cycling then continues with the recharge of capacitor C1. The photo-electric arrangement comprises a photo-cell 26 responsive to the light reflected from a template 41 which is interrupted by a vibrating reed 25. The alternating output from the photo-cell is fed through an amplifier VT3- VT5, rectified by diode 31 and smoothed by resistor R16 and capacitor C7. The direct voltage across capacitor C7 is applied to an amplifier VT6, VT7 having a relay RL2 in its output circuit. The scanning of a mark 20 causes a reduction in the alternating output from the photo-cell 26 causing the current through relay RL2 to fall. The relay releases and a charged capacitor C8 is connected to the relay RL1, since switch SW1 is now in position 39. The relay RL1 is actuated for a period determined by the discharge of the capacitor causing a mark to be made by the punch 13. The photo-cell arrangement for sensing marks is mounted with a known system for following an outline 42 on the substrate 41 employing a photo-cell 23 on the vibrating reed 25.
