Title: Improvements in or relating to a knitting machine
IPC: D04B15/68
Filed: 1961-04-21
Abstract: 927,677. Knitting. SCOTT & WILLIAMS Inc. April 21, 1961 [May 4, 1960], No. 14554/61. Class 74 (2). A multi-feed circular knitting machine comprising pattern controlling means for varying the relationship between the needles 6 and the stitch producing elements 12 which co-operate therewith, wherein, associated with each feed, is a member which can be latched in a series of positions in each of which a different set of pattern elements thereon controls elements individually associated with the needles. As shown, latch needles 6 slide in slots 4 of a rotary cylinder 2, the needle butts 10 being engaged by stitch cams 12 to lower the needles and their jacks 14. The downward movement of each jack is limited by the engagement of shoulder 18 with a spring band 20. Removable cams 24 hold the jacks with the edges 22 of their parts 22, 23 sliding on the bottom of the slot while lower parts 28, 30 diverge from the bottom of the slot, shoulders 32, 34 being provided at the lower end of the jack. Engaging the edge 30 of each jack is the edge 60 of a presser 44 having a series of butts 50 which can be broken off according to the pattern required. Fixed cams 58 hold presses 44 so that the lower ends of the jacks are always slightly flexed inwardly. Associated with each feed is an adjustable assembly 62 which carries the cams 36 and 58 for that feed, and has a portion 64 with horizontal guide ways for slides 66 corresponding to the butt levels of the pressers 44. Each slide has a cam extension 70 which engages the corresponding butt 50 and is biased outwardly by a tension spring 71 so that its outer end 68 engages corresponding butts of the two pattern elements 90 and 92 (not shown) carried in a vertical slot 89 in a tuck wheel 76. The base 78 of wheel 76 has sockets 80, one corresponding to each of the slots 89, which are engaged by the nose of a manually operated spring-biased plunger 82 to secure the wheel in position. The combination of butts 50 and the butts of elements 90 operates on the jacks when lowered either to leave them in their normal position or push them in to a lesser or greater extent. When the jacks are in their normal position shoulder 34 will project the maximum amount permitted by cam 58 and engages notch 40 in cam 36 so that the cam rise 42 will lift the jack to clear the loop and form a plain stitch. When the jack is pushed in to the smaller extent, shoulder 32 will engage 42 and the needle will only be raised to tuck level. If the jack is moved fully inwards, shoulders 32, 34 both miss edge 42 and the needle is not raised sufficiently to tuck so that a float is formed. A fabric with tucks T and floats F, such as shown in Fig. 8, may be produced.

Title: Production of lacquered aluminium or aluminium alloy strip or sheet
Inventor: LISTER LESLIE
IPC: C25D11/06
Filed: 1967-03-30
Abstract: 1,235,661. Anodizing aluminium. ALCAN RESEARCH & DEVELOPMENT Ltd. March 15, 1968 [March 30, 1967], No.14691/67. Heading C7B. An aluminium or aluminium alloy strip is provided with a thin e.g. 0À05 micron oxide coating by passing it through an aqueous sulphuric acid bath at a temperature of not less than 50‹C. but below the bath boiling point so as to have a dwell time in the bath of 0À5 to 15 seconds and passing A.C. between the strip and at least one electrode in the bath to provide a current density at the strip surface of at least 20 amps./sq. ft. Preferably the aqueous bath contains at least 20 to 25% sulphuric acid by weight and is used at 80 to 100‹ C. with a current density of 60 to 160 amps. / sq. ft. with a dwell time of 2 to 7À5 seconds. The resultant oxide coating has comparatively large craters (300 to 400A diameter) which provides a good anchorage for lacquers used in the canning industries so that the lacquer coating is not detached by mechanical deformation of the strip in can manufacture. Comparative tests are given for an aluminium alloy containing 2% Mg and 0À25% Mn subjected to different current densities and bath dwell times. The process may be effected by feeding the strip through a shallow tank divided into strip entry and exit and two central compartments by partitions having a slot with a rubber gasket through which the strip passes, the slot in the central partition having a rubber gasket, counter electrodes being arranged parallel to opposite faces of the strip in the two central compartments and connected so that current passes along the strip which is alternately cathodic and anodic. Prior degreasing of the strip is unnecessary. As an alternative the electrolyte may be fed in counterflow to the strip movement so that grease on the strip is prevented from contaminating the oxide coating, electrolyte containing freed grease overflowing a weir at the strip entry end of the tank.

Abstract: 680,214. Addressing machines. ADREMA, Ltd. Sept. 4, 1950 [June 3, 1949], No. 14968/49. Class 100 (ii). A feeding mechanism for continuous stationery operating in synchronism with an address or like series-printing machine, comprises a primary feeding device which engages the stationery and effects the greater part but not the whole of its movement from one printing position to the next at a relatively high speed and a secondary feeding device which engages discontinuities e.g. punched holes in the stationery to complete the feeding movement at a relatively low speed. The stationery is fed over a horizontal table 1 secured over the existing machine, to a printing position 2 at which printing is effected by a printing head 3 operatively connected to both the primary and secondary feeding devices. The printing head 3 is carried on an arm 4 having an extension 4a, Fig. 2, coupled to the primary feeding device by a link 11 and a crank 12 fixed on a shaft 13 so that as the head 4 is moving to effect impression, shaft 13 is rocked 90 degrees clockwise, and a crank 14 adjustably carrying a spindle 15, Fig. 1, actuates a push rod 18 pivotally connected to a bush 19 which slides on a tubular guide rod 20. The bush carries a pivoted pawl 24 so that on the rearward stroke it engages in a punched hole in the stationery and feeds it at a high speed away from printing position, the entry of the pawl 24 being facilitated by adjustable bars 27, 28 which hold the edge of the stationery raised from the table 1. The feeding of one form length is completed by the low speed secondary feeding mechanism at the commencement of the next printing stroke before printing is effected. The secondary feed device comprises a plate 29 fixed to the shaft 13 adjustably connected to a link 30 slidingly moving a bush 31 on guide rod 32 and carrying a bar 34 which slides on framework edges 33. The bar 34 supports a metal plate 35 having an upwardly extending pawl 36 which feeds the stationery by engaging discontinuities or perforations therein. The pawl 24 can be transversely adjusted by rotating rods 22 which move sleeves 21 carry-- ing the guide rod 20, the push rod 18 being slidingly coupled at 16, 17 to the spindle 15. Pawl 36 is transversely moved by sliding the plate 35 on the bar 34. Adjustably secured to the bush 19 through one of a number of spaced holes, is a buffer 25 which at the forward end of its sliding movement engages a spring mounted collar 26 to damp the movement and assist correct engagement of the pawl 24 with the stationery. Duplicate forms may be accommodated and pass onto the table over rollers 5 and 6, a carbon sheet being drawn from a roll 7 advanced slowly by a ratchet and pawl 9 from a push rod 8 operated by the printing arm 4.

Abstract: 1,143,041. Controlling burners. FENWAL Inc. 3 April, 1967 [5 April, 1966], No. 15123/67. Heading F4T. An ignition control system for a gas burner 1 includes an electrically operated fuel valve 5, a manually or thermostatically operated switch 23 and a monitoring and control circuit 17 (shown in Fig. 2) providing spaced unipolar pulses of high voltage to spaced ignition electrodes 29, 31 which are bathed by the flame of the ignited fuel and act as flame responsive elements, the circuit 17 being arranged to open the valve 5 only when ignition sparks have been established and to close the valve if the flame is extinguished or the electrodes 29, 31 are short circuited. As shown in Fig. 2, one of the electrodes 31 has located therein a thermistor 41 which is connected in series with a resistor 39, the two resistors being in parallel with the impedance 37 of a circuit-breaker 33 so that when a flame is present the thermistor 41 diverts sufficient current from the circuit-breaker to prevent it operating but when flame fails the thermistor cools quickly and the circuit-breaker 33 operates to disconnect the solenoid 11 of the valve 5, allowing the valve to close. The thermistor arrangement may be replaced by a thermally sensitive switch which is open at ambient temperatures. In a further modification the electrodes 29, 31 are spaced further apart so that sparking does not normally take place in the absence of ionization caused by a flame. The voltage is increased for a period to provide ignition sparks.
