As shown, cylinder needles 2 are associated with sliding elements with projections 5' on which jacks 6 are pivoted. Each jack has a sideways bent tail 6<SP>1</SP> which can engage any of three, notches 7 in the adjacent trick liners so that either butt 6<SP>2</SP> or butt 6<SP>3</SP> engages a cam track or neither butt engages a cam track. Each tail 6<SP>1</SP> engages between two tines at the upper end of one of the selector jacks 10 these jacks having long and short butts 10<SP>1</SP>, 10<SP>2</SP> and having alternate blanking butts 13<SP>1</SP> and 13<SP>2</SP> at their lower ends. Jacks 10 are selected by a track of selector cams 32 pivoted on shaft 330 and selected by a drum to engage butts 10<SP>1</SP>, 10<SP>2</SP> so that according to whether cam 32 is selected, engages a short butt or engages a long butt, the tail 6<SP>1</SP> will engage one of the three notches 7 and the associated needle will knit, miss or tuck. Dial jacks 22 are pivoted to the needles 21 and have extensions 24 which can each engage one of three notches 26 and are controlled by selector jacks 27 which rock about a fulcrum 40. To avoid resetting the patterning arrangements some alteration of the pattern produced maybe achieved by altering the cams in some of the cam tracks so that needles selected to tuck will knit as well as those already selected to knit or those selected to knit will tuck along with those selected to tuck. Amongst a large number of possible fabrics a rib fabric with tuck stitches may be produced Fig 14.

Abstract: 1,097,389. Endless conveyers; shrink wrapping apparatus. LERNER MACHINE CO. Ltd. Sept. 22, 1966 [Oct. 1, 1965], No. 41763/65. Headings B8A and B8C. The relative speeds of endless conveyers 3, 4, 6, 11 are predetermined to provide smooth transfer of stacked cartons 1 wrapped in film 2 as the cartons are conveyed from a wrapping machine to a shrinking tunnel (not shown). Belts 3, 4 move the stacks intermittently at the wrapping machine speed, and parallel belts 6 run continuously at half the speed of the belts 3, 4. The conveyer 11 operates in the shrinking tunnel and its chains 13 move at quarter the speed of the belts 3, 4. Rollers 15 are freely mounted on the chains but revolve when they engage tracks 17 so that the stacks 1 are propelled through the tunnel at twice the chain speed. The drive for the belts 6 is via a sprag clutch. When a stack is discharged from the belts 3, 4 it causes the belts 6 to override their drive and those of the rollers 15 which are under the stack will revolve to suit the speed of the stack. A spring-loaded plate 18 improves the pressing action of the belts 6 on to the stack whose speed now falls to the positively driven speed of the belts 6 which is the same as that of the conveying speed of the driven rollers 15. Rollers 12 between the conveyers 3, 11 are free running.

Title: Superconductive memories
IPC: G11C11/44
Filed: 1965-10-06
Abstract: 1,090,422. Semi-conductor devices. RADIO CORPORATION OF AMERICA. Oct. 6, 1965 [Nov. 2, 1964], No. 42472/65. Heading H1K. [Also in Divisions E4 and H3] A memory device comprises a plurality of superconductor loops extending perpendicularly from an insulating substrate with means for selectively establishing persistent currents in the loops. In Fig. 1, a lead ground plane 10 is covered with a silicon monoxide layer 12 on which are a plurality of digit lines 14, 14a consisting of a tin layer 16 in contact with a lead layer 18 except for a bridge portion 20 which forms the conductive loop. The word lines consist of lead strips 24, 24a, which penetrate each loop. If a current I D  is applied to a digit line, the current flows mainly through the tin strip 16 until a word current pulse Iw is passed through an appropriate conductor 24 when the combined magnetic field drives the tin 34 under the bridge portion normal so that the digit current is diverted to flow through bridge 20. If the word current Iw and then the digit current I D  is terminated, a persistent current is set up round the loop. Information is read (destructive read-out) by applying a current to a word line so that, if persistent current is flowing, the tin is driven normal and the resulting discharge of loop current energy develops a voltage across the tin portion. In a modification, the word line lead is positioned immediately outside the loop, and in a further modification (Fig. 7, not shown) a " bit-organized " memory is formed by providing X and Y lead strip conductors inside each loop of an array so that the tin strip is driven normal when all three currents (X, Y and digit) coincide. A further embodiment is described (Fig. 10, not shown) in which a 2 x 2 array is formed by having two loops interlacing at each operative point. A modification of this arrangement is also described (Fig. 11, not shown) in which each word line 210 is subdivided into a plurality of word storage locations each of three bits, 218, 220, 222.

Title: Variable pitch fans for turbofan engines
IPC: B64C11/32
Filed: 1974-10-01
Abstract: 1484683 Axial-flow fans GENERAL ELECTRIC CO 1 Oct 1974 [1 Oct 1973] 42540/74 Heading F1C In a turbofan engine, a variable-pitch fan comprises a fan blade 34 having a shank 38 journalled in an aperture 32 in the periphery of a disc 30 and rotatable by pitch-varying means comprising a shaft 60 fixed to and rotatable with the disc, a sleeve 66 surrounding the shaft and connected to it by recirculating ball spline members 70 disposed at a helix angle which may be zero to permit purely axial movement of the sleeve relative to the shaft, and a casing 76 surrounding the sleeve and connected to it by recirculating ball spline members 80 disposed at another helix angle, whereby movement of the sleeve produces rotational or other movement of the casing. When the sleeve 66 is moved by mechanical or electrical means or, as shown, by hydraulic pressure applied to one side or the other of an annular piston 102, the casing 76 is thereby rotated relative to the shaft 60 and acts via a gear 54 and sector gears 50 to adjust the pitch angle of the blades 34. The blades are held in the adjusted position by a pitch lock comprising a collar 140 and an annular piston 152, each constrained by axial splines against rotation relative to the shaft 60 and the casing 76 respectively, teeth 156 on the piston normally engaging teeth 144 on the collar 140 to lock the casing 76 against rotation relative to the shaft 60. When hydraulic pressure is applied to the piston 102 to move it in either direction, it is also applied to the piston 152 to move it against the action of Belleville springs 160 to disengage the locking teeth 144, 156. A signal representative of the blade pitch angle is afforded by sensing the axial position of the piston 102 by means of a number of sensors disposed about the circumference of the shaft 60 and each comprising a rod 126 connected to the piston and thereby movable axially as a core within a coil 132, the coil comprising an autotransformer in which a voltage applied to the primary is opposed by a voltage induced in the secondary, the difference of the voltages being sensed to provide a measure of the core position for indicating the blade pitch to the pilot or providing an input to an engine control system. A bleed orifice 210 provides a flow between the two sides of the piston 102 to minimize any difference of temperature between the fluid on the two sides.
