Title: Pitch varying mechanism for variable pitch fan
IPC: F04D29/32
Filed: 1971-12-11
Abstract: 1375988 Axial-flow fans ROLLS-ROYCE (1971) Ltd 5 Dec 1972 [11 Dec 1971] 57658/71 Heading F1C [Also in Division F2] A pitch varying mechanism for a fan comprises an actuator mounted on non-rotating structure and operable to produce a rotational output corresponding to the required degree of pitch change; an epicyclic differential gear having two input gears one of which is driven by the shaft which drives the fan rotor and the other of which is driven by the rotational output, and adapted to produce an output at a speed corresponding to the sum of the shaft speed and a speed proportional to the speed of the actuator output; a pitchchanging reduction gear driven by the output from the differential gear and having an output in the form of relative rotation of two output gears; and bevel gears one connected to each of the fan blades, and which are driven by the output gears to rotate the fan blades about their longitudinal axes. The differential gear comprises planet gears 32 carried in a cage 33 and meshing with a stationary annulus gear 31 and a sun-wheel 34 splined to the main shaft 13 of a ducted-fan gas turbine engine. Further planet gears 36 carried by the cage 33 mesh with a normally stationary annulus gear 30 and a freely rotatable sun gear 37. When the annulus gear 30 is stationary, the sun gear 37 rotates at the same speed as the sun gear 34 and the shaft 13. When the blade pitch is to be changed, the annulus gear 30 is driven in one direction or the other by means of a drive motor controlled by a pilot's lever through a mechanical feedback, whereby the sun gear 37 is caused to rotate faster or slower than the shaft 13 and therefore has a rotation, relative to the shaft 13 and the fan rotor 11, 12 carried by the shaft, in one direction or the other. The sun gear 37 is geared at 50 to eight planet wheels 52 carried by a cage 57. Teeth 53 on the planet wheels 52 mesh with annulus gears 54, 56 each of which is fast with a respective bevel gear 75, 79 meshing with a number of common bevel gears 71 each of which is connected through a respective torque tube 15 to a respective fan rotor blade. The rotation relative to the shaft 13 given to the sun gears 37 produces a rotation of the planet wheels 52 about their own axes and a rotation of the cage 57 about the shaft 13. Annulus gear 54 has eight more teeth than annulus gear 56, and consequently a relative rotation is produced between the annulus gears. This relative rotation is constrained by the engagement of the bevel gears 75, 79 with the bevel gears 71 to consist of an equal and opposite rotation of the relatively rotating parts, and the fan blades are consequently turned about their longitudinal axes to a different pitch angle.

Title: Numerical control apparatus for a shear
IPC: B23D33/10
Filed: 1971-12-17
Abstract: 1329909 Automatic control of position CINCINNATI Inc 17 Dec 1971 [4 Jan 1971] 58722/71 Heading G3R [Also in Division G4] In a shearing machine having a gauge bar which is automatically numerically repositioned after each cut, the mean position of the bar is kept constant for a given setting by adding or subtracting any error due to under-or over-shoot to the command for the next cutting cycle. Thus such errors are non-cumulative. Input command pulses (e.g. one per À001 inch) are automatically or manually supplied to a data device 13, from whence they are passed via 14 to a reversible counter 15 for comparison with position feedback pulses from an encoder 18. The difference controls positioning motor 11 via a controller 17. Command and feedback signals are also compared at 16 after the bar has come to rest, any difference being used to modify the contents of counter 15. The other "boxes" shown are associated with the machine sequencing.

Title: The manufacture of films from an organic thermoplastic polymer
Inventor: KRAUNGEN PETER HENDRIKUS VAN
IPC: B29C48/10
Filed: 1968-12-31
Abstract: 1282283 Improved process for tubular films SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ NV 13 Oct 1969 [31 Dec 1968] 61899/68 Heading B5B A process for manufacturing organic thermoplastic polymer films comprises continuously extruding the polymer downwards as a tubular film, expanding the tube by inflation and flattening the tube to a partially collapsed form by passing it through collapsing elements which also simultaneously cool the film below the melt temperature of the polymer by contacting it with layers of a cooling liquid which is forcibly supplied to the surface of the collapsing elements. The process excludes that claimed in Specification 1,190,028. Forcibly supplied cooling liquid includes gravitationally or hydraulically supplied liquid, but excludes cooling liquid supplied by merely dipping the collapsing elements in a bath of cooling liquid. Thus the cooling liquid may be supplied by pouring the liquid on the surface of the collapsing elements at a position above the area of contact with the tubular film or it may be supplied to a plurality of locations on the surface of the collapsing elements through a plurality of conduits in the wall of the collapsing elements, especially when the conduits are pores. The apparatus may comprise, as shown in Fig. 1, a melt-extruder terminating in an extrusion die 12 through which a tubular film 11 is extruded downwards and inflated by internal gas pressure. The collapsing elements may comprise two shallow boxes 13, 14 which expose a porous surface 13a, 14a to the collapsing film through which the cooling liquid, which is preferably water, is forced from a supply through inlet tubes 19, 20, thus cooling the film. The water exuding from the porous plates is collected in the bath 15. The film is fully collapsed by the nip rolls 16, 17 and wound up. The porous face of the collapsing elements, which may be porous metal plates, may be planar as shown in Fig. 1, convex in the direction of the film (which includes rollers) and/or convex transverse to the direction of the film so that a straight front of the advancing film comes into contact with the cooling surface (as opposed to the parabolic front A in Fig. 1 for planar collapsing elements). Alternatives to porous surfaced collapsing elements are illustrated in Figs. II, III, IV, IX (not shown). The process may be used for polypropylene film, when the efficient cooling of the film results in a film of high clarity and good physical properties.
