Title: Flexible couplings single piece link
IPC: F16D3/79
Filed: 1965-05-12
Abstract: A flexible coupling comprises a unitary member 4 of straight sided polygonal shape (square as shown) made up from at least four laminations of resilient metal and connected, on diameters at right angles, by axial pins 5 to shaft heads 1, 2. The link 4 may increase in thickness at its extremities, e.g. corners, where it is connected, to the pins 5, by means of lamin[mu] 41 of successively decreasing length (Figs. 6, 9 and 10, not shown). Discs 6 having apertures spigoted on one pair of pins 5 and loosely surrounding the other pair may be provided to take up the drive in the event of failure of the link. Fig. 8 (not shown) illustrates a double coupling in which an intermediate member (9) is connected by its end flanges 2 through two such links 4 to shaft hubs 1. Figs. 11 and 12 (not shown) illustrate the link pin clamping washers (10) having one face (11) dished or corrugated to increase unit bolt load pressure. Axial flexibility of the link 4 may be increased by making the length of the link arms (L1) (Fig. 2, not shown) fractionally greater than the centre to centre distance be tween connecting pins 5 such that the link arms buckle as in Fig. 4 (not shown), an axial force-deflection graph (Fig. 5, not shown) illustrating the effect of this arrangement

Title: Improvements in control switches incorporating indicating means
IPC: H01H25/06
Filed: 1965-06-19
Abstract: A switch has an operating member which can be pushed to operate one set of contacts acted on by springs surrounding plunger and cylinder arrangements, and which can be turned to operate other contacts on a bar acted on by a return spring. The operating member 1 is secured to a spindle 11 carrying a cam 13 which by rotation of the member 1 through 180 degrees co-operates with a plunger 14 or 15, depression of which operates with snap action normally-open and normally-closed contact sets 16, 18. Rotation of the spindle actuates contacts 27 via cams 30, the spindle being located at 90-degree steps by spring-loaded bars 22. The spindle may be locked by a cylinder lock and bolt 7, 8, and/or by an electromagnetic lock 33. An indicator lamp 6 is included in the arrangement shown, but an electromagnetic indicator may be used (Fig. 9, not shown). Several switches may be ganged together by gearing (Fig. 6, not shown).

Title: Method of making coaxial cable
IPC: H01B13/26
Filed: 1967-06-08
Abstract: The longitudinal seam of the outer conductor of a coaxial cable is sealed by overlapping the edges 60, 62, Fig. 4, orienting the conductor to form a gap 134, Fig. 12, which is directed downwardly, heating the conductor and providing solder in the gap. The cable is formed from a tin-plated steel tape 12, a narrower conductive copper or aluminium tape 14, and an adhesive band 20, Fig. 1, which joins up with a centre conductor 36 carrying spacer discs 42. The edges of the tapes are aligned by a device 24, Fig. 1, the tapes are heated at 26 so as to soften band 20, so that rolls 28 can squeeze the tapes to form a ribbon 30. After air cooling, the ribbon is corrugated by rolls 32 and then passes to former 34, Fig. 5, whereupon the ribbon is rolled into an outer-conductor 44 around the conductor 36. An adjuster 46 rolls conductor 44 so that the edge 60, Fig. 4, has a smaller radius than its adjacent edge 62, whereupon a sizing device 48 overlaps the edges and the cable passes to a soldering device 50, from whence it passes through a capstan 10 on to a take up spool 54. The stand 68, Fig. 5, can be tilted by a device 69 so that the seam is located at 45 degrees to the horizontal, Fig. 4. Soldering device.-The soldering device 50 comprises an induction heating apparatus 100, Fig. 9, movable relative to cable 49, a rosin-cased solder wire 108 fed from a spool 110 towards the cable by a gear 112, a guide tube 116, and a cooling trough 126. The power supply to the coil 96 of apparatus 100, and the control 124 of the solder feed motor 122, are both connected to the capstan 10, so as to vary their values according to the feed rate of the cable. The molten solder flux 136, Fig. 13, is drawn into the seam by capillary action.

Patent ES-352031-A1 (ES)
Title: Improvements relating to Machines for Transferring Data.
IPC: F17C5/00
Filed: 1968-03-27
Abstract: An annular magnetic data track carried by an article 3 is centred 7 for a read-out by a head 26 rotatable about the central axis and movable radially and axially, its operative surface being parallel to the axis when in use. As described, gas bottles 3 are lifted from a conveyer until a protective collar 18 whose inner surface carries the track abuts the rim 17 of the outer one 14 of three coaxial barrels 14, 13, 36. An hydraulic ram 11 lowers the barrels until the outer barrel 14 is stopped by a fixed sleeve 16, in which it is splined for vertical movement, then the inner barrels 13, 36 continue to be lowered against spring 15 until an abutment 19 engages the barrel 14, the intermediate barrel also being confined for vertical movement only. In this position, a cam 14a operates plunger 28 to energize a motor to rotate the inner barrel 36 which carries the head 26 on an outwardly biased arm 21 normally cammed inwardly by extension 20 of barrel 14. The head is rotated 360 degrees then reversed as the barrels are raised, the head conductors passing up through barrel 36 and out through opening 31 to a tray on which they are coiled to permit rotation. Data handling.-A binary-coded number allocated to each article is recorded three times in the track, preceded each time by a succession of pulses (Figs. 9, 10, not shown) which on read-out operate a threshold circuit 140, Fig. 11, controlling a gate 150. The data is coded as positive pulses for "ones" and negative pulses for "zeros". On readout, the first recorded number is stored in memory 160 until the second number is read out whereupon the data stored in 160 is transferred to 170 while the second number is stored in 160. The procedure is extended to memory 180 for the third number and a comparison made in unit 200 of each number thus stored, cell by cell, and the majority number transferred to memory 210 for subsequent decoding. The system may provide a warning (not detailed) if the threshold pulses occur before the memory is filled.

Title: Normally vented liquid-storage tank for ships, with closure device for automatically preventing leaking if the ship should sink
IPC: B63B25/08
Filed: 1973-06-13
Abstract: A shipboard storage tank for liquids, such as petroleum products or chemicals. To prevent pressure buildup, and to permit overflow during filling, a vent and overflow conduit is provided. In order to prevent this vent and overflow conduit from becoming a source of pollution if the ship should sink and also in order to prevent loss of the contents of the tank upon sinking, the invention provides an anti-pollution valve installed in the conduit, which automatically closes the conduit, should the ship sink. The anti-pollution valve is actuated to its closed position by the hydrostatic pressure as the ship sinks and it automatically equalizes the pressures between the sea and the liquid within the tank as the vessel sinks to deeper depths. Transient effects, such as surface waves, are prevented from actuating the valve. The anti-pollution valve also includes means that make it possible to dump the liquid out from the tanks of sunken ships and thereby salvage it.
