Abstract: 1,233,728. Fluid-pressure servomotor systems. NORMALAIR-GARRETT Ltd. Nov. 21, 1969, [Nov.25, 1968], No.55778/68. Heading G3P. A fluid-pressure servomotor system of the kind having a fluidic amplifier system 17 controlled by a sensor 30 and operating a servomotor 10, has a pair of valves 32, 33 which, when actuated, operate the servomotor directly. The system may control the temperature of an air conditioning system, but as shown it regulates the cabin pressure of an aircraft by moving valve V in accordance with pressure changes in duct 12 detected at orifice 30 and fed to control inlet 28 of amplifier 22. The other control inlet 29 of this amplifier and the power supplies 20, 21 and 44 are obtained from the duct 12 via a pressure regulator 18. Changes in the pressure at inlet 28 act through a second stage amplifier 23 to selectively inflate bellows 41, 42 which control valve spool 47 which regulates flow to motor 10. Solenoid valves 32, 33, when opened, vent the control inlets 28, 29 so causing valve V to be moved to either a fully open or shut position. In various modifications Figs. 2,3,4 and 5 (not shown) motor 10 has a rolling diaphragm piston, amplifier 17 and/or valve 40 are replaced by vortex amplifiers and valves 32, 33 are actuated manually.

[Also in Divisions C7 and F2] A composite article made substantially of metal is produced by assembling at least two components into an assembled shape, at least one thereof being a foam cellular structure, and then coating the assembled shape with metal, thereby integrally joining the components and producing a composite article having substantially the same configuration as the assembled shape. The metal coating may be deposited by electrodeposition and may be silver, copper, nickel, iron or an alloy. The foam material may be of polyurethane, and this may be joined by the deposited metal to a solid material such as resin reinforced with carbon or glass fibre, carbon, glass, ceramic, fire brick, plastics material or metals. The polyurethane foam may subsequently be ashed out. In the examples, a mild steel plate and a mild steel cylinder are plated with nickel when in contact with a layer of polyurethane foam, the foam layer being within the copper cylinder. The latter resultant composite article may be used as a seal or bearing.

Abstract: 1324878 Filled cable PIRELLI GENERAL CABLE WORKS Ltd 13 Oct 1771 [15 Oct 1970] 49013/70 Heading H1A [Also in Division D1] An unsheathed cable core is fully filled with, e.g., petroleum jelly in a relatively liquid state which is subsequently cooled to a non-viscous state whilst the cable passes continuously along a straight line path. As shown, a telecommunications cable passes through evacuation chambers 26b and 26a, and then into filling vessel 12. Petroleum jelly is heated to about 90‹ C. and passes, possibly under pressure, through line 22 to the cable; the surplus being drawn off through line 24. The filled cable passes into chamber 20 where it cools, possibly by feeding in carbon dioxide under pressure and allowing it to expand; thereby extracting heat from the core. A line 21 may make good any loss of jelly occurring during passage of the cable through the chamber. The core may then be wound with tape insulation and reeled on to a drum for later sheathing; or sheathing may take place in tandem with the above operations. Seals 32, 34, 36, 38 may comprise annular members which encircle the cable and are arranged to inflate against it. An alternative seal comprises bunched resilient fibres defining a central hole through which the core passes. Lubrication of the seals is described, and pipe 37 feeds heated petroleum jelly on to the core to form a wipe of jelly which lubricates seals 32 and 34. Seals 36 and 38 are directly lubricated by leakages from the vessel 12.

Abstract: 1329044 Friction clutch CONCENTRIC PUMPS Ltd 31 July 1971 36117/71 Heading F2C A cooling fan, having blades 20, for an internal combustion engine is driven when a wax cell thermostat 46 mounted in the water impeller 44 actuates a clutch by means of the rods 48 and 50 within the driving spindle 40 from a pulley 18. As shown the fan has a hub 10 rotatable mounted on a hub 14 which is part of the pulley 18, plates 24 and 26 of the clutch being attached to the pulley and a plate 22 being attached to the fan hub 10, a cross-bar 36 passing through the hub 14 and the shaft 40 moving a presser plate 34 to actuate the clutch when a rod 50 acts against it due to operation of the thermostat. Springs (not shown) serve to separate plate 34 from a backing annulus 32 when the thermostat cools and the rod 48 is withdrawn into it. An alternative embodiment is shown in which a diaphragm spring attached to a movable collar on the hub of the pulley serves to actuate the clutch on engagement of a single rod 50 with an adjustable screw on a member within the collar. The adjustment of the screw adjusts a certain free play in the linkage between the rod 48 and the clutch and so alters the point at which the thermostat (and so the temperature) causes the clutch to engage.
