Title: Improvements in or relating to joints or terminating devices for co-axial conductor electric cables
IPC: H01R13/646
Filed: 1938-03-07
Abstract: 515,683. Joints for co-axial electric conductors. PIRELLI-GENERAL CABLE WORKS, Ltd., and SOPER, R. E. S. March 7, 1938, No. 7062. [Class 38 (i)] Relates to means for jointing co-axial conductor cables comprising plug and socket elements 6, 7, Fig. 1, connected to the central conductors 23 of the cables and two annular members, 1, 1 connected to the outer conductors 24, 24. According to the invention, the inner and outer connecting members are separated by a pair of washers 2, 3 with an intermediate layer 9 of plastic composition which is forced against both members when the washers are pressed together, for example, by a nut 4, thereby making a tight insulated joint between the two members. The washers may also bear against the bevelled sides of a shoulder 8 on the central member. Further sealing is provided by means of Chatterton's compound at 5. One annular member is surrounded by a union nut 12 adapted to engage screw threads 15 on the other member to fasten the joint together. The union nut is locked in position by a disc formed with a lug for engagement with a notch in the rim 19 of the union nut and with slots for the reception of a set screw screwed into a tapped hole 21 in the annular member 1 on which the threads 15 are formed. The face of one nut 4 is grooved and the face of the other nut 4 provided with a lead insertion 16 to ensure good contact and a tight joint between these nuts. Jointing members of this kind may be provided at the ends of flexible connector cables.

Title: Improvements in the manufacture of packing for fluid pressure joints
IPC: F16J15/08
Filed: 1927-03-14
Abstract: 273,616. Webmetal Joints, Ltd., and Mills, J. S. March 14, 1027. Joint-making packing. - Packing for fluid pressure joints such as described in Specification 273,560, [Class 122 (iii), Steamengines, Kinds &c.], is formed by pressing a sheet of metal c e.g. of aluminium between dies a and b so that the depth of the packing i.e. the triangular part is greater than the thickness of the original sheet. The packing is then detached from its sheet by passing between flat dies or rollers which shear it away at the edges. In forming a gasket with parts of varying thickness, the male die is widened on these parts to force more metal into a deeper triangular section.

Title: Dual purpose reciprocating pumps
IPC: F04B9/14
Filed: 1954-03-12
Abstract: 747,221. Reciprocating pumps for fluids. WETTLEY, E. E. March 12, 1954, No. 7206/54. Classes 8(1) and 102(1). A reciprocating pump comprises a cylinder 4 and a piston 23 attached to a rod 24 that is pivoted to a lever 55 that can be oscillated in a plane containing the axis of the cylinder 4 to give a full stroke of the piston and deliver liquid at a low pressure. When it is necessary to deliver liquid against a high pressure, the lever 55 is rotated about the axis. of the cylinder 4 to give a shorter stroke of the piston with a higher mechanical advantage. The rear face of the piston is formed with cam lobes 28, 29 that co-operate with cam lobes 31, 32 fixed to the end of the cylinder so that as the piston rotates, it is also reciprocated. Fig. 4 shows the cam lobes 31, 32 formed of sheet metal and secured by a flange 33 gripped by the cylinder cover 6. The cam lobes slope at 37, 38 so that the piston 23 is retracted before alignment of the faces 39, 40 ; the suction stroke is effected by the spring 62. Instead of the faces 39, 40, the cams may be shaped to cause a gradual drop ; the cams may be formed integral with the end of the cylinder or cap 6. The lever 55 is pivoted on the arm 66 which is pivoted on the cylinder 4. The lever 55 may be bifurcated and guided on the arm 66 and also on another arm extending on the other side of the cylinder and may be locked to these arms. The pump is shown as attached to a trailer and drawing through a non-return valve from a reservoir 12 and delivering, past a non-return valve to a trailer jack 14.

Abstract: 1,215,532. Feeding and delivering sheets. DERITEND ENG. CO. Ltd. 10 Feb., 1969 [14 Feb., 1968], No. 7297/68. Heading B8R. Sheet feeding apparatus comprises a roller pair, a guide member extending towards the nip of the roller pair, means for blowing air through, or about, the guide member, and a plurality of vortex chambers connected to the surface of the guide member, for creating suction to draw a sheet towards the guide member. Fig. 1 illustrates apparatus in which sheets are delivered from the cylinders 10, 11 of a printing press, or die-cutter, to feed rollers 13, 14 over guide plate 20. Sheets are prevented from remaining on periphery of cylinder 11 by means of air under pressure directed by bores 42 under castellated leading strip 22 of plate 20, and they are drawn to no the surface of plate 20 by suction applied through bores 54 from vortex chambers (52), (Figs. 2, 3, not shown) with tangential entry passages (64) at their bases. Alternatively, air under pressure can be applied to the vortex chambers (52) which, because of their design, still create suction in the central areas of bores 54. The degree of suction in chambers (52) can be adjusted by a valve plug 56 or by controlling the fan (not shown) at the end of suction pipe 72, which preferably acts on the blowing source through pipe 32.

Abstract: 566,305. Lubricating systems. ASPIN, F. M. May 12, 1943, No. 7572. [Class 12 (iii)] In a force-feed lubricating system subject to cyclic load variation, the lubricant pressure is also varied cyclically by synchronized release of pressure. The pump 21, Fig. 3, supplies the main duct 22 and through resistances 39 the branch ducts 23, pressure control being provided by a branch duct 24 closed by a valve 25 with a variably loaded spring. This spring may be connected to the engine throttle pedal so that the loading and hence the oil pressure will increase with depression of the pedal. With a rotary valve 10, Fig. 1, mounted in a housing 11, the branch duct 12 leads to a control ring 16 keyed to the valve. This ring has a partial groove 18 which registers with an outlet 20 from the duct 12 and has outlets 19 at each end, the parts 18, 20 being in register to release the oil pressure during that part of the cycle when the bearing pressures are a minimum. The supply to duct 12 may come from a pipe 31, Fig. 5, controlled by a piston valve 30 connected to a diaphragm 36, the upper surface of which is subject to the variable pressure in the induction manifold through pipe 37. Oil is supplied from pipe 33 to valve 30 by way of a chamber 32 having a spring- loaded valve 34 connecting to a release passage 35. When the engine is idling, diaphragm 36 rises so that valve 30 closes and valve 34 opens.

Abstract: 1498061 Viscous couplings; differential gear GKN TRANSMISSIONS Ltd 20 Feb 1976 [25 Feb 1975] 7757/75 Headings F2D and F2W In a multiplate viscous shear coupling for an inter-wheel or inter-axle differential gear wherein sets of plates 57, 59 are respectively splined to a housing 23 and a hub 43 defining a chamber containing viscous liquid and at least one of the sets of plates are free to slide axially, the chamber is connected by ducts 61 to an expansion chamber formed within the hub 43 and containing a spring loaded piston 46. The viscous liquid initially occupies between 85 to 100% of the chamber volume and during operation the heat generated in the liquid causes the latter to expand. When the liquid completely fills the chamber, further expansion causes the piston 61 to move against its spring bias and the accompanying pressure increase in the chamber is stated to cause axial movement between the plates which increases the torque transmitted by the coupling. By selecting the filling of the chamber and the rate of spring loading of the piston 46 a desired torque transmission/ temperature characteristic may be obtained. When the coupling temperature attains a maximum permitted value the piston 46 moves into an enlarged portion 64 of the hub bore to permit liquid to flow around the piston and thus reduce the pressure in the chamber. The viscous liquid may be silicone oil having a viscosity between 1000 and 150,000 centistokes and preferably of 100,000 centistokes at 25 C. and zero shear rate. The plates 57, 59 may be nickel plated mild steel and may have holes or slots formed therein. As shown in an interwheel differential gear having an input pinion 11 meshing a crown wheel 14 fast with a casing 15 carrying planet pinions 17 which mesh side wheels 19, 20, the coupling casing 23 is connected between the side wheel 20 and one half shaft 22 whilst the hub 43 is connected to the other half shaft 21.
