IPC: E02F3/12
Filed: 1967-11-06
Abstract: 1,189,320. Lubricating. " WESER " A.G. 6 Nov., 1967 [5 Nov., 1966], No. 50377/67. Heading F2A. [Also in Division E1] Lubrication points in a travelling machine element are lubricated by means of a lubricating-head which is displaceable by the machine element and travels therewith during the lubricating of a machine point, the lubricating - head being mounted on a rocker so as to be movable in two directions, said rocker being urged by resilient biasing elements so that the lubricating-head is moved towards the lubrication point and having abutments connected thereto which engage surface zones of the machine element at an angle to one another to limit the movement of the lubricating-head by the biasing elements. The rocker may be movable in two directions at right angles, the two surface zones also being at right angles, and the abutments may be rollers. In an embodiment link-pins 9, Fig. 2, of bucket chains of bucketchain dredgers are lubricated by means of a lubricating apparatus 8, Fig. 1. The latter has lubricating heads 13, 14, Fig. 2, each of which is mounted on a rocker 17 or 18, and has rollers 31, 33 or 32, 34 engaging a link 10. The rockers 17, 18 are pivoted at 29, 30 respectively; are moved angularly by means of piston/cylinder units 27, 25 and 28, 26; and are connected by linkages 21, 22 which are mounted in bearings 19, 20 carried by an auxiliary bucket ladder 4 of the bucket-chain dredger and are coupled by means of a piston 23 and a cylinder 24. In use, the piston/cylinder units are actuated by means of valves (not shown); the rollers are held against the respective faces of links 10; and lubricating nozzles 15 and 16, carried by the heads 13 and 14, are each aligned with a lubrication point 12 provided in each link-pin 9. A plate 11, mounted between links 10, is connected to a bucket 6, Fig. 1, of the dredger.

Abstract: 1453288 Magnetic heads COMPAGNIE INTERNATIONALE POUR L'INFORMATIQUE 31 Oct 1973 [7 Nov 1972] 50691/73 Heading G5R A magnetic head for recording and playback has part of a coil 5 located in a transducing gap defined between a pair of composite polepieces; each polepiece having a first layer 4, 6 of magnetically soft material adjacent the coil, and a second layer 3, 7 located between the first layer 4, 6 and an outer, third layer 2, 8 of magnetically hard material, the second layer having a structure which will magnetostatically decouple the first and third layers from one another. The layers 4 and 6 are ineffective during recording giving an effective transducing gap length of e2, Fig. 4, layers 2 and 8 being inactive during playback whereby the effective gap length is e1. The layers 2 and 8 are of high saturation induction and flux density, substantially zero remanent flux density material with relative permeability greater than 50, such as cobalt, iron-cobalt alloy, or preferably pure iron. The layers 4 and 6 are of low saturation flux density, very high permeability material, such as iron-nickel alloy, with the easy axis of magnetization parallel to the gap width (i.e. parallel to L3, Fig. 1). Layers 2, 8 and/or layers 4, 6 may each be formed by a stack of magnetic films, the films being electrically insulated from one another. The layers 3 and 7 may be of non- magnetic dielectric material, such as silicon dioxide, or may each be formed by a stack of films of alternate magnetically soft and hard magnetic materials. The various layers 2 to 8 are formed by vapour deposition in vacuo on a substrate 1. Coil 5 is an insulated multi-turn, flat coil, with at least one turn bared at the transducing gap. The width L1 of layer 2, 8 may be equal to but is preferably greater than the width L2 of layers 4, 6, whereby the write track is wider than the read track.

Title: Apparatus for escaping from high buildings
IPC: A62B1/12
Filed: 1973-11-01
Abstract: 1408477 Safety lowering apparatus JOHNSON ENTERPRISE CO Ltd 1 Nov 1973 50854/73 Heading B8B Apparatus for escaping from high buildings comprises a frame 1, for attachment against the wall or window sill outside the building, on which is mounted a winch drum 11 by a shaft 10 connected to a gear train 14, 16, 17, 19. A pair of parallel screwed rods 15, 18 having threads in reversed directions is threaded into nuts 20a 20b in a plate 21 connected by a piston rod 24 to a piston 23 in an hydraulic cylinder 22. Pressure built up in the cylinder 22 by the unwinding of winch cable 12, due to falling of an escaper attached to cable end sling 32, rotating the gear train 14, 16, 17, 19 to move the plate 21 along the screwed rods 15, 18 is fed to a valve assembly 26 and thence to a brake cylinder 28 which actuates a brake assembly 13 to check the motion of the winch drum 11 and thereby arrest the falling of the escaper. The valve assembly 26 incorporates a spring-loaded piston rod 222 with a piston 221; receives pressure from the cylinder 22 through an inlet tube 27 and passes it on to the brake cylinder 28 through an outlet tube 29 when the pressure compresses spring 226. A leak tube 210 enables the pressure in the brake cylinder to 28 to drop and release the brake assembly 13 when the arresting action on the drum 11 causes the pressure in the cylinder 22 to drop. The drum 11 thus resumes rotation and the cycle repeats, the escaper thus falling to the ground intermittently.

To wind glass filament 15, Fig. 1, into layer 14 of uncured polymer on mandrel 1, the filament is wound about and fed by possibly detachable mandrel extension 3 and grooved spacer roller 4, and is guided to guide 6 traversed by worm 7 by constant-length guide 8 comprising tubes 9, 10 pivotally connected to one another, to guide 6 and to an anchorage point adjacent extension 3. Alternatively, the path length is maintained by passing the filament about pulley 20, Fig. 4, freely slidable and rotatable on shaft 21 lying parallel to the mandrel but also being inclined to the mandrel axis in plan view, Fig. 5. The compensator may comprise rigid links with exterior guides, or a flexible tube, or rigid links flexibly interconnected. The resulting reinforced sleeve may be used as hose, or may be cut to form endless belts. The mandrel may have axial teeth to provide internally toothed belts.
