The bobbins are removed by a mechanism which advances towards the row of bobbins on the spindles, doffs a plurality of full bobbins, recedes with the doffed bobbins whilst a bobbin transferrer 51 advances towards the row of spindles, and transfers the bobbins onto the poles 51. Doffing full bobbins: (Figs. 3-12 not shown). The travelling carriage stops in front of a group of spindles, the doffing base 40 moves towards the spindles and grippers 36 swing down to grasp the tops of the full bobbins. The grippers 36 then swing upwardly and the doffing base moves away from the spindles. Simultaneously, the poles 51 move forward so that the device is in the position illustrated in Fig. 1. Transferring doffed bobbins to storage cage. The grippers 36 carrying the doffed bobbins swing down to deposit the full bobbins onto the poles 51, release the full bobbins and swing upwardly. The poles 51 carrying the bobbins swing under their own weight towards the carriage (Fig. 9) and the poles and full bobbins are moved away from the spindles to a position above the storage cage 54. The poles 51 are then caused to tilt further and deposit the full bobbins on rails in the cage. Arranging bobbins in storage cage. When the full bobbins are deposited on rails 57, the rails are lowered to bring empty rails to the receiving position. The cage can be reciprocated between doffing movements to arrange the bobbins in vertical, preferably zigzag, columns. Donning empty bobbins. The empty bobbins 1 are donned by lowering a chute near the empty spindle and allowing the empty bobbin to fall into place. The empty bobbins are positively located in position by pushers 8. Removing bobbins from storage cage. (Fig. 26 not shown). The full bobbins are removed from the cage by placing the cage on a conveyor belt (242), lowering the rails to deposit the bobbins onto the conveyor and then operating the conveyor.

Title: Variable geometry nozzle capable of producing a silencing effect
Inventor: HOCH RENE GERARD
IPC: F02K1/38
Filed: 1967-09-19
Abstract: 1,204,691. Jet propulsion nozzles. SOC . NATIONALE D'ETUDE ET DE CONSTRUCTION DE MOTEURS D'AVIATION. Sept.19, 1967 [Oct. 7, 1966], No. 42716/67. Heading F1J. The invention relates to a variable area jet propulsion nozzle comprising two series of flaps pivotally mounted at the end of the jet pipe, the arrangement being such that the flaps may assume a smooth internal contour for normal thrust or a corrugated shape for noise suppression operation. The nozzle assembly comprises a jet pipe 14 and an outer casing 3 which together define an annular duct 4 for flow of ambient air, ports 5 being formed in the casing 3 for inflow of further ambient air. A series of pivot pins 10 and 12 are disposed at the downstream end of the jet pipe, the pivots being disposed in the form of a polygon. A series of plain flaps 30 Fig. 4 are mounted on the pivots 12 and a series of hollow flaps 15 are mounted on the pivots 10 so that the flaps 30, 15 are disposed alternately around the nozzle. The flaps 30 are adjustable by means of an actuator 22 acting through an axially movable ring member 24 and linkage. The flaps 15 are adjustable by means of an actuator 11 acting through an axially movable ring member 13 and linkage. The flaps 15 are of rectangular cross-section and are curved in longitudinal section. Flange members 20 and 36 are secured at the side faces of the hollow flaps 15 (see Fig. 8) and the edges of the adjacent plain flaps 30 engage therebetween, the flanges diverging in the downstream direction. Assuming the actuators 22 are actuated to position the plain flaps 30, the actuators 11 are not actuated so that the flaps 15 are free to pivot outwardly about the pivotal axes 10 under the influence of the gaspressure within the nozzle so that the side flanges 36 abut against the ends of the flaps 30 which are in a fixed position. This is the position assumed for normal operation, the internal contour of the nozzle being smooth. Now if the actuators 11 are actuated to position the hollow flaps 15, the actuators 22 are not actuated so that the flaps 30 are free to pivot outwardly about the pivotal axes 12 under the influence of the gas-pressure within the nozzle so that the flaps 30 engage against the side flanges 20 of the hollow flaps 15 which are in a fixed position. The internal configuration of the nozzle is thus of corrugated form this being the position assumed for silenced operation of the nozzle. The hollow flaps 15 permit the inflow of ambient air. A thrust reverser assembly is indicated in Fig.1. In a further embodiment the hollow vanes are not curved in longitudinal section.

Title: Production of olefin polymers
Inventor: COOPERSMITH JOHN MAYER
IPC: C08F10/00
Filed: 1959-12-21
Abstract: A cyclic process for polymerizing an olefin comprises passing the olefin through a cooling zone and then into a reaction zone, introducing catalyst at the inlet of the reaction zone, diluting a major portion of the reaction zone effluent with incoming olefin charge comprising fresh charge and recycled unreacted olefin in an amount sufficient to stop the reaction, recycling the thus diluted portion of the reaction zone effluent through the cooling zone and reaction zone, withdrawing the residual minor portion of the reaction zone effluent for product recovery and recycling unreacted olefin from said residual minor portion to the incoming olefin charge. Catalyst in the withdrawn stream may be converted to an adduct (e.g. by the use of NH3) which is then removed prior to the addition of an oil to form a solution of polymer in lubricating oil.  The process is applicable to the polymerization of propylene, alpha-methyl styrene, butene and butene/isobutene mixture, but is advantageously applied to the polymerization of isobutylene using BF3 as catalyst.  Up to 20% of closely boiling hydrocarbons also may be present.  The invention is illustrated by reference to a suitable apparatus.

Title: Improvements in or relating to circularly polarised microwave apparatus
Inventor: MARK JOHN RICHARD
IPC: H01P1/17
Filed: 1960-12-21
Abstract: 948,827. Aerials. MARCONI CO. Ltd. Aug. 10, 1961 [Dec. 21, 1960], No. 43888/60. Heading H4A. [Also in Division H1] The symmetry of a circularly polarized (CP) wave is preserved by reflecting back, in suitable phase, components of the wave which are reflected by the asymmetric horn 8. In the radar system shown, a wave propagated in a square waveguide 2 with a direction of polarization indicated by vertical vector E is converted by polarizer 6 into a CP wave and radiated by rectangular-section horn 8. The asymmetry of the horn causes partial and unequal reflection of the orthogonal components of the wave with consequent loss of circularity. The horizontal component of the reflected energy is shifted in phase by the adjustable phase-shifter 4 and re-reflected towards the horn by a short-circuit 3 consisting of an array of horizontal conductors. It is stated that loss of circularity is compensated if the phaseshifter is suitably adjusted. The phase-shifter comprises a horizontal sheet of polystyrene vertically movable by means of an insulating threaded rod 5.

Title: Improvements in or relating to swaging machines
IPC: B21J13/10
Filed: 1961-12-11
Abstract: 977,150. Swaging machines. GES FUR FERTIGUNGSTECHNIK UND MASCHINENBAU G.m.b.H. Dec. 11, 1961 [Jan. 7, 1961], No. 44159/61. Heading B3H. A swaging machine has an hydraulically operated work gripping and feed device 3 controlled by valves 31, 33 operated by limit switches actuated by the movement of the feed device through adjustably positioned cams to interrupt the feed, which cams have associated therewith members 7 with oblique surfaces 8 adapted to act on a feeler 10 controlling an additional slide valve 12 in the hydraulic circuit which, during the interruption in feed, corrects any deviation of the feed device from its desired position. The gripping head 3, which may also rotate the workpiece, is moved along a bed by a piston 5 in cylinder 6. Pressure oil from a reservoir 25 is supplied by a pump 24 driven by an electric motor 23 through check valve 27 and pipes 29, 30 to the inner side of piston 5 where it acts continuously to bias the head 3 to the right. Additional pressure oil may be supplied when necessary through conduit 28. The feed movement to the left is initiated by magnetically-operated valve 31 which admits pressure oil to the outside of piston 5 either through magneticallyoperated valve 33 for high-speed movement or through a throttled by-pass 35, 36 for lowspeed feed movement. When a cam on the head 3 actuates a limit switch, the valve 31 is closed to stop the feed and simultaneously a further magnetically operated valve 38 is opened which admits pressure from pipe 30 through regulator 39 to both pipes 15 and 40. This causes a balancing pressure to act on the outer end of piston 5 and on the feelercontrolled slide valve 12 which is loaded by spring 14. Any further displacement of head 3, caused for example by the hammer tools acting on the workpiece, produces a movement of the feeler 10 which operates the valve 12 to change the pressure acting on piston 5 and hence connect the displacement. A stepping switch subsequently re-energizes the valve 31 to continue the feed movement and simultaneously valve 38 is closed. The valve 12 may alternatively be carried by the head 3 and the member 7 mounted on the bed.
