Title: Apparatus for the Treatment of Strip-Like Material, more particularly Tyre Cord Fabrics
IPC: G05D15/01
Filed: 1967-08-31
Abstract: 1,199,966. Automatic tension control. CONTINENTAL GUMMI-WERKE A. G. Aug. 31, 1967 [Sept.16, 1966], No.39865/67. Heading G3R. In a system for automatically controlling tension in travelling strip material, movement of a roller, under which the strip passes, opposes a force applied to a force transducer controlling strip driving torque. In Fig. 2, tyre cord fabric 2 issuing from a drier (not shown) forms a loop round a roller 4 carried by endless chains 7 engaging sprockets 8 fixed to a shaft 9. Shaft 9 is biased by weights 11<SP>1</SP>, 12 attached to the ends of a chain 11 engaging a sprocket 10. The arrangement is such that, with no tension in the fabric, the force applied to transducer 13 by weight 12 is equal to the maximum loading of the transducer. Then, when fabric tension has the desired value, transducer loading is reduced. Deviations of tension from this value are automatically corrected by consequent variations of transducer output which, after amplification, control the torque of an electric motor (not shown) driving feed rolls for the fabric. If tension becomes excessive, weight 12 rises from transducer 13 and operates a switch 16 to deenergize the motor. Biasing by springs instead of weights is referred to.

Title: Method and apparatus for controlling a machine tool
IPC: B23Q15/04
Filed: 1971-07-28
Abstract: 1363851 Machine tool details BONEHAM & TURNER Ltd 28 July 1971 [20 Aug 1970] 40052/70 Heading B3B In a method of automatically controlling a machine tool to machine successive components to within predetermined limits comprises an automatic tool setting up cycle and an automatic machining cycle that compensates for tool wear. The specific embodiment discloses a component 1 that has to be bored to a tolerance of Œ0À0005 inch after initial rough boring. A tool 2 on a boring quill 5 traverses the component and is withdrawn. An air gauging head "A" is used to measure the bore. As the tool wears the bore size diminishes until when it is at -0À0003 inch below the mean final diameter a signal from the gauging head "A" passes through a transducer to a linear stepping motor to reposition the tool. The component is removed and another substituted. This cycle is repeated until the linear stepping unit has reached its limit of forward adjustment. When a component is produced to - 0À0005 inch below mean diameter a signal is produced to illuminate a warning light and prevent a further automatic cycle. Indicator gauge "A" is taken out of circuit and indicator gauge "B" put into circuit. The linear stepping unit is reversed to move the tool to a fully retracted position and then advanced by a pre-selected amount to eliminate back lash and place boring quill 5 in a reference position. Tool 2 is then indexed to position a new cutting edge or is replaced by a new tool. A component is placed on the machine and the tool caused to traverse it whereupon indicator gauge "B" measures the bore. A signal produced from gauge "B" is fed through the transducer to activate the linear stepping unit which feeds the tool a required amount. The cycle is repeated until the component is within Œ0À0003 inch of its mean diameter whereupon a signal will cancel the automatic tool setting sequence, put indicator gauge "A" into circuit and allow the automatic cycle to become operative. An electronic gauging head could take the place of the gauging heads. A cycle counter could be set to stop the machine after a predetermined number of automatic cycles.

A lift-link 4 of a tractor three-point power-lift mechanism is connected to a draft link 6 by a bolt 11 which passes through an aperture in the draft link and a slot in the forked end 5 of the lift link. The bolt is bent to form a portion 8 to which is secured a web 12 arranged to fit into the slot in the forked end 5 as shown whereby a rigid connection is made between the lift link and the draft link. If the web 12 is removed from the slot against the action of a spring 14 and the bolt portion 8 together with the web 12 is turned through 180 degrees relative movement between the lift link and the draft link is then possible. The slotted portion 10 of the forked member is shorter than the slot into which the web fits so that when relative movement is permitted the web will not enter into its slot. This connection may be disposed between the lift link and the lifting arm of the rock shaft.

Process for continuously disentangling, straightening and aligning textile fibres e.g. of scoured or unscoured wool, cotton or synthetic material comprises gripping a thick layer of entangled fibres (thick relative to a layer fed to a carding engine) e.g. by rollers 53 while feeding it to a pin bearing cylinder 54 rotating with a surface speed greater (e.g. four times) than the speed at which the fibres are fed so that the pins comb, draft and transfer the fibres to the cylinder. The fibre web then passes to a further pinned cylinder 55 rotating at a faster speed (e.g. four times faster) than roller 54. The fibres are removed from cylinder 55 by a cylinder 57 which has only four rows of pins arranged in diametrically opposed pairs. Its surface speed is approximately ten times that of cylinder 55 from which it removes the fibres in tufts to lay them in overlaping relation of a cylinder 58 rotating with surface speed only slightly greater than that of rollers 53. The thick fibre web is then transferred by belts 62, 63 and a roller 64 to a further pair of feed rollers 65. The actions of the parts 53 to 65 may be repeated several times before being fed to further pin cylinders 66, 67, 68 running at progressively increasing speeds and with progressively increasing pin density. The fibres are then stripped by rollers 71, condensed at a funnel, 72, passed through cadender rollers 73, and then passed to a coiler and sliver can. The rollers 53, 65, 71 may be smooth or fluted metal or of rubber or synthetic elastic material or they may be wrapped with saw tooth wire. The pins on cylinders 54, 55, 66, 67, 68 may be fixed and set radially or inclined to the cylinder surface. Alternatively as in Fig. 4 and more particularly in Figs. 2 and 3 (not shown) the pins may be mounted in rows on bars which are slidably mounted in slots in the cylinder surface and the bars be moved by cam means so that the pins are retracted at points where the fibres are removed from the associated cylinder. In addition the angle of the pins to the cylinder may be varied during rotation. The pins of adjacent cylinders may or may not intersect. The pins in cylinder 57 may also be retractable. In place of cylinder 58 a wire mesh belt may be used. Streams of air may be directed to assist transfer of fibres between the cylinders and rollers and to this end the cylinders and rollers are perforated.

Low levels of sodium ion concentration in e.g. boiler feed-water can be measured by a sodiumresponsive glass electrode and a calomel reference electrode if the pH value is maintained in excess of about 9 by the addition of a buffering solution e.g. ammonium hydroxide or ethanolamine or ammonia gas. As described the test liquid and buffer solution are pumped to a mixing cell (13) Fig. 1 (not shown), to allow air bubbles to settle out, and then flows by gravity to a test cell (22) with a magnetic stirrer (23). The cell signal is measured by a millivoltmeter and a recorder having a "high" contact controlling an alarm circuit. A timer periodically actuates valves in the circulating system to replace the test solution by a standard solution for calibration.
