Title: Arrangement for locating disconnections on a transmission path
IPC: H04B17/40
Filed: 1974-11-28
Abstract: 1453337 Locating faults in transmission lines INTERNATIONAL STANDARD ELECTRIC CORP 28 Nov 1974 [6 Dec 1973] 51576/74 Heading G1U In a four-wire transmission system Fig. 1 including a plurality of repeaters RS1, RS2 fed with constant direct current through the inner conductors of a coaxial pair, discontinuities are detected by including in each repeater, a switching device S which on reversal of the direction of the supply current for testing is activated by means of a diode D2, and which inserts a series resistor into the next supply section which if this is open-circuit inter-connects the supply conductors through a diode, a resistor, the collector-emitter path of a first transistor and a current-voltage converter. The first transistor T1, Fig. 3, is initially turned on when terminal 3 becomes positive with respect to terminal 1. As soon as current flows through T1, the converter C provides a feedback voltage at C turning the transistor hard 'ON', placing R2 across the supply leads (terminals 1,3). If the following supply section is open-circuit, no supply current will return to flow through R1 and thus T2 will be 'OFF', leaving R2 across the leads. If supply current does flow, T2 is turned ON, shorting the base of Tl turning it 'ON'. Thus each repeater followed by a complete section acts as a series resistor (Rl) and that followed by an open circuit acts as a resistor across the supply (R2). Thus by measuring the voltage across the supply leads at the supply station, the location of the fault can be determined.

Title: Post-cure inflation of pneumatic tyres
IPC: B29D30/06
Filed: 1965-12-08
Abstract: 1,132,229. Moulding tyres. PIRELLI S.p.A. 8 Dec., 1965 [30 Jan., 1965], No. 51964/65. Heading B5A. A device for removing from the mould of a tyre curing unit a pneumatic tyre which is to be subjected to inflation by a post-inflator, includes a carriage 1 slidable horizontally on guides from the mould to the lower part 3 of a postinflator and vice versa, an element 2 vertically movable on the carriage and constituting the upper part of the post-inflator, the element having a peripheral seat and means to hold the upper bead of the tyre temporarily on the seat. The lower part of the element includes means which interlock with the part 3. At the end of the working cycle, which is operated automatically with the aid of microswitches, the tyre is received on an inclined roller conveyer 4 and discharged. After the curing operation the mould is opened and the carriage 1 brought above the lower part of the mould and the element 2 lowered. A fluid motor 47 is energized, causing a forked lever 44 to rotate a member 40 in the element 2 whereby a circumferentially spaced set of pins (58), Fig. 5, not shown, are moved radially outwardly from the member 40 to act on a set of pivoted elements (63) causing them to rotate about their pivots and grip the upper bead of the tyre. The element 2 is then lifted by the energization of fluid motors carried thereon, and which include pistons (28), Fig. 3, not shown, with toothed racks (29) which rotate sprocket wheels (30) on a shaft (31). The latter drives sprocket wheels (35, 37) which engage vertical racks (36, 38) on the carriage. Thus the tyre is removed from the lower mould part, and when the element reaches its uppermost position on the carriage the latter is driven along guides 13, by a motor and chain drive, to a position above the part 3, whereupon the element is lowered by the energization of its fluid motors. During this lowering movement, the element engages arms 87 of the platform 4 causing it to rotate about pins 79 and against the action of springs 81 to -the horizontal position. After the lowering of the element 2 the motor 47 is again operated and the member 40 rotated to free the tyre bead from the elements 63 and causing teeth on the lower part of the member 40 to engage with teeth on the inflator part 3. Inflating fluid is then fed to the tyre via a duct 74. On raising the element 2 the tyre is disengaged and falls on to, and passes down, the platform 4, and engages a lever 90 which operates a microswitch to initiate a new cycle.

Title: Improvements in and relating to diesel pile hammers
IPC: E02D7/12
Filed: 1967-11-20
Abstract: 1,209,318. Pile driving hammers. FMC CORP. 20 Nov., 1967 [2 Dec., 1966], No. 52664/67. Heading B3H. A diesel pile hammer has a free piston or ram 55 reciprocable in a cylinder 28, 29 and forming therewith a power chamber 50 within which gases are compressed during the downstroke of the ram and are subsequently supplied with fuel and ignited by fuel injection means 78, a scavenging chamber 53 connected by a conduit 70 with the power chamber and into which burnt gases are drawn during the upstroke of the ram, and means 95 for lifting the ram to its starting position. The lower surface of the piston 55 has a hemispherical cavity 73 which co-operates with a similar cavity 74 in an anvil 39 to form a combustion chamber 72, Fig. 1A, into which fuel is injected by a nozzle 78 supplied from a fuel injection pump 61, Fig. 11, actuated by a follower 60 engaged by a cam surface 59 on the falling ram 55. The quantity of fuel dispersed is controlled by remote means (130), Fig. 3A (not shown). The follower also actuates a lubricant pump (62). Anvil 39 is connected through cushion adapter plug 43, cushion 44 and driving head 42 with the pile 151. A pin 52 prevents rotation of the anvil. The larger diameter upper portion of the ram defines a bounce chamber 54, Fig. 11, communicating with an auxiliary bounce chamber 86 through port 81 which is closed by the ram upon excessive upward movement whereby the increase in pressure in the bounce chamber 54 provides rapid deceleration of the ram. During its subsequent downstroke under gravity assisted by the pressure in chamber 54 the ram causes the gases in scavenging chamber 53 to be discharged through conduit 70, ports 122, power chamber 50 and ports 77. When ports 122 are closed by the falling ram, a valve 126 opens to atmosphere. For both manoeuvring the hammer and lifting the ram to its starting position, a hoist rope 95, Fig. 1, passes around sheaves 117, 118 and is attached to a lifting mechanism 30, Fig. 2A (not shown), slidable in guides in the hammer and cooperating with an hydraulic damper (100), (103), Fig. 9 (not shown) for cushioning its downstroke. A rod 93 attached to mechanism 30 extends through a bush 89 and is adapted to engage a shoulder 90 on the ram for lifting it. A latch (98), Fig. 2A (not shown), actuated by a rope (99) is arranged to lock the mechanism 30 to the hammer to enable the latter to be positioned upon a pile by the lifting rope 95. In another embodiment, Figs. 16-21 (not shown), a one-way reed valve (141) is provided between the power chamber 50 and conduit 70 to prevent transfer of gases between the scavenging and power chambers during the downstroke of the ram. In a further embodiment, Fig. 22 (not shown), the conduit 70 is connected by a further conduit (143) with the bounce chamber 54.
