Title: A new or improved method of, and means for, patterning a pile fabric
IPC: D06B11/00
Filed: 1960-12-21
Abstract: <PICT:0938734/IV(a)/1> Yarn printing apparatus is characterized in that the yarns to be printed are drawn in sheet form across a series of dye-troughs each containing a different colour and a pick-up roller partially immersed therein, means are provided whereby the sheet of yarns is normally supported clear of the several pick-up rollers, and control means are provided which operate in accordance with the pattern to be produced whereby the yarns can be pressed either collectively or individually against any selected pick-up roller, or any two or more selected rollers in succession, during their passage through the apparatus to suitable take-up means.  In the apparatus shown several yarns A are drawn-off and wound-on beams B and C respectively.  Rollers D at opposite ends of the apparatus and similar rollers E in a finishing chamber behind the printing unit G maintain the yarns A in parallel coplanar relationship. Mounted within unit G are a series of dye-troughs H disposed transversely of and beneath the sheet of yarns.  Each trough A contains a partly immersed pick-up roller K which extends the full width of the sheet of yarns A and rotates in the opposite sense to the direction of movement of the yarns.  Somewhat in front of each roller K is situated an applicator roller L operated by solenoid M so as to cause all the yarns A to be pressed against roller K.  Energization of each solenoid M is effected by micro-switch N having its operating lever O actuated by cam P which is continuously rotated at a speed dependent on the linear speed of the yarns.  The profile of cam P and the speed thereof controls the length of and the interval between the periods during which the yarns engage the roller K, the arrangement being such that the gaps left unprinted by the first roller K are printed in one or more different colours by subsequent rollers.  Directly above each roller K is a row of pads Q depressible by solenoids R to apply selected individual yarns to the roller. The solenoids R are operated by a conducting cylinder S and spring contacts T so as to produce repeated pattern effects.  On completion of the printing the yarns are subjected to fixing, washed off and dried within the chamber E, prior to being reeled up at C.

Abstract: 1,150,680. Ultrasonic inspection devices. AUTOMATION INDUSTRIES Inc. 29 Sept., 1967 [18 Oct., 1966], No. 44422/67. Addition to 1,141,046. Heading H4D. A system for ultrasonically inspecting a workpiece comprises rotatable cylindrical transducers for engaging the workpiece, and means responsive to that part of the ultrasonic energy which persists in the workpiece when transmission into the workpiece has terminated. In the Fig. 1 embodiment for detecting delaminations in plywood panels 12 fed to testing station 14 by conveyer 24, pulse transmitting transducers 26 on arms 34 pivoted at 35 are moved into contact with a panel by pneumatic cylinders 36 which exert a pressure insufficient to compress unbonded plies together but sufficient to ensure good acoustic coupling through resilient tyres on the transducer surfaces. The transducers are paired with similar receiving transducers on pneumatic cylinders 42. Gate circuits coupled to the receiving transducers effect blanking of received signals during the transmission pulse period so -that only ultrasonic energy reverberating between the upper and lower panel surfaces is detected. If such energy is not detected in a predetermined interval the presence of a de-lamination of a corresponding predetermined size is indicated and paint sprays are actuated to mark the panel at the relevant position. Instead of the above through-transmission inspection, a pulse-echo inspection is envisaged. The transducers (Fig. 3) comprise piezo-electric cylinders 52 rotatable on ball-races 50 and having a resilient rubber or polyurethane tyre 60. Electrical signals to or from the cylinders are coupled inductively to external circuitry via coaxial rotor coil 56 and stator coil 58.

Each section SD-Fig. 2-serves a number of subscribers Q who have access to a channel circuit frame B, e.g. via a concentrator 100. Frame B contains a plurality of channel circuits, Fig. 1 (not shown) each of which switches a speech signal (incoming at 10) into one of the channels of the RETURN highway AP and also switches the corresponding return channel (incoming at 20) into the return speech signal. The frequency translation is effected using, for each direction of transmission through a channel circuit, both a fixed frequency mixer (11, 21) and a mixer whose control input is derived from a programmable, variable frequency generator (2). Each channel of GO highway AF corresponds to a single channel of the RETURN highway AP. Channel switching is effected in the control centre by a two-branch circuit 90-95. Signalling is carried out in a separate signalling channel-52 to 56 kHz. Each frame circuit and the control centre are equipped with a signalling channel circuit. Allocation of channels for a two-way connection is carried out by the control which transmits control signals to the variable generators of the two channel circuits involved in a connection. A number of the above-described systems may be interconnected via a regional control centre, Fig. 4 (not shown).
