A circular multifeed knitting machine with provision for tucking and welting has, at each feed, a fixed main stitch cam and an adjustable auxiliary stitch cam which act in succession on different butts of a needle. At four feeds 14-17 are mounted fixed raise cams 26, tuck raise cams 27, guard cams 29, 30, main stitch cams 24 and movable auxiliary stitch cams 25 with guard cams 28. The needles have six butts acting in confined pathways at cam levels 18-23. At say feed 15, all needles with butts at levels 19 and 20 will be raised to clearing height by cams 26, with butts at level 23 confined by the rear face 24c of main stitch cam 24, all needles with butts at level 22 will be raised to tuck height by tuck cams 27 with butts' at level 23 also confined by cam face 24c and, at tuck height, butts at level 22 guarded by cam 29 and all needles with butts at level 21 will pass through the feed with any overthrown needle being lowered by guard cam 30. All raised needles will then be partially lowered by the fixed main stitch cam 24 acting on butts at level 23 with butts at level 19, 20 or 22 guarded by the rear faces 26b or 27b of cams 26 or 27. Adjustable auxiliary stitch cams 25 then act on all butts at level 18 to fully lower needles to knit height with butts at levels 19, 20 or 22 still guarded by the rear faces of cams 26 or 27. To prevent overthrow all butts at level 18 are guarded by cams 28 which are movable with auxiliary stitch cams 25. A second embodiment with a pattern wheel is described in which the pattern wheel acts on butts at one level and the main and auxiliary stitch cams again act on butts at their own levels.

Title: Improved means for obtaining a variable direct voltage from a source of constant direct voltage particularly suitable for electric traction control
IPC: H02P5/69
Filed: 1945-11-20
Abstract: 605,062. Electricity supply ; exciting dynamoelectric machines. BRITISH THOMSONHOUSTON CO., Ltd., and LEWIS, T. X. Nov. 20, 1945, No. 31222. [Classes 35 and 38 (iv)] [Also in Group XXXVII] Boosting by dynamo-electric machines; systems depending on use of two or more machines.- The armatures 6 and 7 of mechanicallycoupled direct - current dynamo - electric machines are connected in series across a constant voltage-source 1, the machines being differentially excited so that one operates as a motor driving the other as a generator and the variable voltage thus produced across the armature of one of the machines is utilized to supply a load. As shown, the load consists of traction motors 2 and 3, which are connected across the armature 7. The field windings, 8 and 9 of the machine 6, and 10 and 11 of the machine 7, are connected in a bridge circuit which is supplied from the source through terminals A and B, an armature-reaction exciter 12 being connected across the other bridge-terminals C and D. A voltage variable in sign and magnitude is applied to an exciter-field winding 13, so that, according to the position of a potentiometer adjusting-member 15, the potential between the terminals C and D is adjusted to excite differentially the mechanically-coupled machines and vary the traction motor voltage. The series-wound traction motors may be braked by returning power to the supply-lines through the motor-generator set, reversal of the series field windings during braking being prevented by interconnecting them through rectifiers. When the maximum traction motor voltage is reached, the motors may be directly connected to the line by a relay 17 which drops out to close a relay 18 at a pre-determined voltage across the armature 6. Contacts 20 simultaneously disconnect the motors from the mid-point E of the motor-generator set. A damping resistor R may be provided, which is finally short-circuited by the switch Rc. A field winding 16 of the exciter 12, which normally opposed the field winding 13, may be connected across a series field winding of one of the traction motors, so as to be energized in response to the motor current. In this manner the traction motor voltage is varied automatically with the load current. The member 15 may be manually or otherwise operated. An auxiliary motor may be coupled to the machines 6 and 7. Reference has been directed by the Comptroller to Specifications 319,429 and 324,629, [both in Class 38 (iii)].

Title: Production of tubular thermoplastic film
IPC: B29C48/90
Filed: 1964-08-04
Abstract: 1,006,046. Producing tubular films. CANADIAN INDUSTRIES Ltd. Aug. 4, 1964 [Aug. 17, 1963], No. 31607/64. Drawings to Specification. Heading B5B. In the production of tubular film which when flattened by passage through the nip of a pair of squeeze rolls forms a doubled ribbon or " layflat " tubular film of predetermined width by melt-extruding a thermoplastic material such as polyethylene through the annular extrusion orifice of a die to form a seamless tubing continuously withdrawing and flattening the tubing at a predetermined distance from the extrusion orifice and maintaining a constant continuous bubble of a gas in the section of the tubing extending between the extrusion orifice and the line of flattening, the quantity of gas constituting the bubble being such as to inflate the tubing while it is in the formative plastic state, the inflated tubing is passed in the unset condition through a sizing means coaxial with the extrusion orifice and being either an annulus or of annular cross-section, located on or beyond the front-line from the extrusion orifice, said sizing means contacting the tubing so as to simultaneously chill it to the set condition and control its diameter to give tubular film of said predetermined width when converted to a layflat form. The tubing may be cooled to an extent insufficient to bring it to the set condition before it is passed through the sizing means by an external air flow directed on to and around the tubing in the vicinity of the extrusion orifice. The rate of air flow may be adjusted to position the frontline of the tubing so that the sizing means lies on or slightly beyond it in the direction of travel of the tubing. The sizing means may consist of at least one turn of tubing in the form of a helix or a jacketed cylinder through the jacket of which a cooling medium is circulated. When the sizing means consists of one turn of tubing (through which a liquid cooling medium is circulated), the tubing may be circumferentially adjustable in contact with the outer surface of the inflated tubing, the distance between two plates or lugs mounted on the two arms of the helix being adjustable by means of a turn screw.

Title: Improvements in or relating to hydraulic power transmission systems
Inventor: DENNY DOUGLAS FRANK
IPC: F04B1/16
Filed: 1957-10-10
Abstract: 856,258. Radial cylinder and swash plate pumps. BRITISH HYDROMECHANICS RESEARCH ASSOCIATION. Oct. 9, 1958 [Oct. 10, 1957], No. 31723/57. Class 102(1). [Also in Group XXIX] A hydraulic power transmission comprises a pump and motor of the axial-piston type in each of which spool valves are formed integrally with or are rigidly secured to the pistons so that each piston acts as a slide valve for another piston. The pistons may be controlled by swashplates, eccentrics, cams or cranks. As described, the pump has eight pistons 7 and the motor eight pistons 24, the pistons being mounted in a common block 8 connected to the output shaft 26. The pistons 7 are controlled by a fixed-or variable-angle swashplate 6 on the input shaft 1 and the pistons 24 by a swashplate 30 pivoted to the stationary casing 4 and variable in angle by a lever. Each piston 7 has two or three leads and controls ports 12 which lead by axial passages 13 and circumferential and radial passages 14 to the cylinder space of the nextbut-one piston, a port 15 leading to a passage 20 which acts as a low pressure manifold for the return of fluid to the pump side of the transmission and a port 15 leading to a passage 23 which acts as a high pressure manifold for supply of fluid to the motor. On the motor side, the lands of each piston 24 similarly control ports 11a, 12a ,15a, the ports 12a and 15a being connected to the passages 20 and 23 respectively. When the output shaft is driven in one direction, the output of the piston 7 moving inwardly is delivered through the passages 14 and 13 to the port 12 of the piston 7 next-but-one in the opposite direction and is directed by the lands of the latter piston to the high pressure manifold 20. From the manifold 20, the lands of one piston 24 direct the fluid through a port 12a and passages 13a and 14a to the cylinder of a piston 24 displaced 90 degrees in the drive direction and the reaction of the latter piston on the stationary swashplate 30 causes the block and output shaft to be driven. Meanwhile a piston 24 diametrically opposite to the outward-moving piston 24 is passing fluid through the passage 20 to a pump piston 7 which is moving outwards. As the angle of the swashplate 30 is reduced towards the position which the plate is at right angles to a rotational axis, the drive into the input shaft is gradually taken over by the increasing resistance of the pistons 7 since their movement is limited by the extent to which fluid expelled or taken up by these pistons can be accommodated by corresponding movements of the pistons 24. Any fluid requirements of the system to replace losses will be drawn in over ball valves 38 and 39 by a ball-piston eccentric pump 35.

Filed: 1946-10-25
Abstract: 618,553. Wobble-plate mechanism. SPARMANN, E. E. K. Oct. 25, 1946, No. 31771. Convention date, Oct. 27, 1945. [Class 80 (iii)] Rotation of a wobble-plate 3 mounted upon an inclined portion 2 of the main driving or driven shaft 1 is prevented whilst allowing the lemniscate oscillation of points in the plane of the plate by means of a ball joint connection at 7 from a member 4 projecting radially from the plate to a member 8 which is guided on a rod 9 for axial movement parallel to the shaft 1. The rod 9 is offset by cranks 11 from a shaft 10 which is rotated at double the speed of shaft 1. The resultant movement of the point 7 is along a lemniscate curve 77 depending upon the throw of cranks 11 which is made dependent upon the inclination of the wobble-plate crank. In a modification, instead of sliding, the member 8 is connected to the crank mechanism by a Roberts' parallel motion linkage. In another modification, the guide-rod 9 is formed as a tubular member mounted upon eccentrics on the shaft 10.

Abstract: 1,157,871. Magnetic storage or switching apparatus. TELEFUNKEN PATENTVERWERTUNGS G.m.b.H. 15 July, 1966 [17 July, 1965], No. 31824/66. Heading H3B. A flat carrier 15 carries insulated conductors 13, 14 and has apertures 11 defining regions such as 12, each of which is enveloped by a closed magnetic storage layer 16 which is substantially circular in plan view, each region being connected to the main carrier body 15 by four webs carrying the conductors, and a pair of the conductors crossing at right angles in region 12. The magnetic layer is between 0À5Á and 20 Á thick and preferably has an easy axis parallel to one of the conductors. Stored data is changed by rotational switching caused by coincident currents in the conductors, read-out being non-destructive and effected by current in conductor 13 alone. If the easy axis of the film is not parallel to either conductor a storage element can be switched rotationally by a current in only one conductor. To make the store, a sheet of double coppercovered plastics film is treated photochemically to produce apertures 11 through the copper layers and then chemically to extend the apertures through the plastics film. Conductors 13, 14 are produced by photochemically etching the remaining copper layers and are insulated by dipping in varnish. A silver coating is applied to the assembly and an iron-nickel layer is formed, electrolytically or by vapour deposition, upon the silver coating while currents are passed through one or both conductors to produce magnetic anisotropy. Portions of the magnetic layer which lie outside the storage regions 12 may be removed by photo-etching.

Abstract: 960,673. Controlling reactors. GENERAL DYNAMICS CORPORATION. Aug. 20, 1962 [Aug. 23, 1961], No. 31949/62. Drawings to Specification. Heading G6C. [Also in Division F2] In a gas-cooled nuclear reactor control-rod drive mechanism, the rod is moved axially by an electric motor during normal control operations and by a fluid motor when rapid shut-down of the reactor is necessary. A clutch disconnects the electric motor from the rod during operation by the fluid motor. Deceleration of the fluid motor, when the control rod is near full insertion; is effected by a valve which progressively restricts the fluid flow from the motor and which is geared to the rod operating mechanism. A magnetically operated brake locks the electric motor when the latter is de-energized. A further clutch is incorporated to prevent rotation of the lead screw due to axial forces on the control rod caused by the weight of the rod, the coolant gas pressure drop along the rod, or the momentum of the rod during rapid movement. The mechanism is sealed to prevent the escape of reactor gas through the lead screw mechanism and pressurised fluid e.g. helium for driving the fluid motor is stored in an accumulator surrounding the lead screw and connected to an external pressure source.
