Title: Lubricating device
IPC: F04B39/02
Filed: 1973-10-09
Abstract: 1424836 Centrifugal pumps NECCHI SpA 9 Oct 1973 [19 Oct 1972] 47042/73 Heading F1C [Also in Division F2]  A centrifugal pump for lubricating a compressor with a vertical crankshaft 10 uses a tube 15 with an inclined axis to pump lubricant to the crankshaft bearings by centrifugal action assisted by a spiral form, Fig. 3, at the lower end 18 of the tube 15. The tube 15 has a slot 17, facing the centre of rotation 22 to allow entrained gases to escape and a paddle 19 which forms a vortex 25 containing bubbles which reduce noise transmission. The vortex and bubbles are also claimed to assist the removal of entrained gases from the lubricant being pumped.

Title: Improvements in or relating to components for electrical circuits and to circuits formed with said components
IPC: H01C7/00
Filed: 1963-11-29
Abstract: 1,062,046. Capacitors; circuit assemblies. TELEFUNKEN PATENTVERWERTUNGS G.m.b.H. Nov. 29, 1963 [Nov. 29, 1962], No. 47176/63. Headings H1M and H1R. A circuit assembly comprises a stack of plates 1, Fig. 2, e.g. of ceramic, Al oxide or Si oxide, glass or PTFE, each carrying or including an electrical component 3, e.g. a resistor, a coil or a capacitor, and having on or adjacent its periphery a plurality of positions 2 for contacts lying on the circum- .ference of a circle, contacts being disposed in two of said positions and connected to said component; alternatively, the plate 1 may be of ferroelectric, ferromagnetic, piezoelectric, conductive, semi-conductive or resistive material and may comprise a component in itself or with co-operating parts. Preferably, all the plates 1 in a stack have the same number of contact positions and equal angular spacing between the two contacts; the plates may be circular or of regular polygonal planform, the positions for. contacts being holes near the periphery or, preferably, peripheral recesses. The components 3 may be formed by vacuum deposition, either through a mask or with subsequent etching, and the contacts may be formed by metallizing the holes or recesses. Components 3 may be protected by a layer of paint, silicone varnish &c. and identified by projections 7, or notches &c. on plates 1; coloured code-marks indicative of component values may be added to the edges or faces of the plates. In the stack, Fig. 3 (not shown), plates are so relatively angularly disposed that desired connections between components can be effected by soldering together corresponding contacts on adjacent plates with or without interconnecting wires; additional dummy contacts may be provided and interconnected to increase the mechanical strength of the stack. To interconnect two angularly displaced contacts on different plates, a special plate of mica, thin glass, or plastic, having interconnected contacts at the relevant angular positions, is added to the stack; alternatively, the relevant positions are interconnected by wire at a socket-type holder, Fig. 6 (not shown), which is mounted on a printed-circuit board (12) which also carries variable components such as a rheostat (P2). The stack may be mounted on a base having external contacts in the form of soldering tabs, snap-in fasteners, or preferably plug-pins which co-operate with the holder on the printed circuit board (12). To assist heat dispersal, all plates should have good thermal conductivity, and special plates should have larger diameters than normal plates. Heat-conducting layers may be sandwiched between the components in a stack. The construction of a specific circuit assembly is described in the Specification.

The B.C.E. may be isomerized to 1-phenyl-2-cyclohexyl ethane which in turn may be dehydrogenated to form bibenzyl. This isomerization may be carried out with a supported platinum or palladium catalyst at 150-550‹ C. Stilbene may be formed by the dehydrogenation of B.C.E. with an alumina or chromia catalyst at 400- 800‹ C.

Abstract: 1,244,395. Turbines; gas turbine plant. FORD MOTOR CO. Ltd. Sept.26, 1969 [Sept.26, 1968], No.47413/69. Headings F1G and F1T. A gas turbine engine having a compressor driving turbine 12, a separate power turbine 22 and support structures 16, 28 for the shafts 31, 68 of the turbines 12, 22 respectively, has a stator shroud assembly 26 supported by pivot joints on the hubs 30, 73 of the structures 16, 28. The shroud assembly 26 consists of a one piece outer annular shroud 50 joined by angularly spaced streamlined pins 52 to a first part 54 of an inner annular wall, and by spaced struts 56 to a second part 58 of the inner wall, thus defining an annular working gas path 59. The outer shroud 50 supports angularly adjustable power turbine nozzle vanes 60. At its upstream end the shroud assembly 26 is rigidly secured at 49 to a volute chamber 14 through which the working gas flows from the combustion chamber to fixed nozzle vanes 48. Adjacent the latter the volute 14 has an annular inwards projection 44 having a part spherical end surface 42 supported by a corresponding part spherical surface 40 of a ring member 38 slidably splined on the hub 30. A spring 46 bearing on member 38 urges the surfaces 40, 42 together. The other end of the shroud assembly 26 is supported in similar manner by the engagement of a part spherical surface 74 on wall 58 with a corresponding surface 76 on the hub 73 of structure 28. Should the structures 16, 28 flex during engine operation the part spherical joints permit the shroud assembly 26 to pivot so that the radial clearances between the rotor blades 34, 66 and the assembly 26 remain substantially the same. Sealing and cooling air is supplied through duct 86 to a labyrinth seal 83 surrounding compressor driving shaft 31, the air also forcing oil from passage 90 through shaft bearing 32. Sealing and cooling air is also supplied through duct 94 to labyrinth seal 96 around power shaft 68, some of the air passing through a bore 102 into the interior of shaft 98, and over an accessory driveshaft 24 to a chamber at the left hand end of the shaft. The chamber is sealed from hot gases by carbon rings 92. The engine may drive a motor vehicle.

Title: Labelling apparatus
IPC: B65C9/00
Filed: 1976-11-16
Abstract: The labelling machine has a plurality of stations (4, 5, 6), arranged along a closed circular path (3), for glue coating, label dispensing and label transfer and, on a rotating carrier, a plurality of eccentrically arranged extraction elements (1) having a curved receiving surface (2), the radius of which is smaller than the radius of the path (3), the said extraction elements rolling on the surface of a gripper cylinder (6). With the carrier and gripper cylinder (6) rotating in the same direction (P1, P3) and with the extraction element (1) rotating in the opposite direction (P4), the axis of rotation (M) of the carrier is located within the circles (9) which coincide with the curved receiving surface (2) in an outer middle position of the extraction elements (1), the distances (a, b) being equal. The geometrical relations make it possible to achieve a small pitch of the gripper cylinder and therefore a high throughput capacity of the machine by means of few extraction elements. <IMAGE>

Patent GB-1123223-A (GB)
Title: Improvements in or relating to the manufacture of flat glass
IPC: C03B18/16
Filed: 1965-11-19
Abstract: <PICT:1123223/C1/1> In a 'float' process for making flat glass, a buoyant, depressable barrier to flows of molten metal in the bath, mounted in the floor of the tank structure, and projecting upwardly in the bath to the vicinity of the surface of the bath, allows localized treatment of the advancing ribbon of glass.  In one embodiment (Fig. 2) the top surface of a seating member for the barrier is level with the floor of the bath, and in the seating member two dovetail grooves 30 extend right across the tank structure.  A bar 31 is held by each groove, the cross-section of the bar being of triangular form, and the bar being made of material of lower specific gravity than that of the molten metal of the bath. The slope of the sides 32 of each bar matches the slope of the inner faces 33 of the dovetail groove 30 so that the bar is retained in the groove.  The top 34 of each bar lies near to the surface of the molten metal under the path of the ribbon of glass 25.  The triangular cross-section of the bar is truncated along that part of each bar which is situated underneath the ribbon of glass.  At the sides of the glass ribbon the bar is not normally truncated, and the apex 35 of the bar projects through and above the surface 9 of the bath of molten metal.  One or more barriers may be employed anywhere along the tank structure to assist in defining a particular zone of the bath where localized treatment of the glass may be effected, and the barriers also serve to prevent glass from the cool end of the tank returning along the tank bottom to the hot end.
