Title: Appliances for automatically stopping delivery of roving and yarn in textile apparatus
IPC: D01H13/18
Filed: 1955-05-04
Abstract: 788,906. Delivery stopping in textile machines. CALVERT, Ltd., I. & I., and TATE, C. May 3, 1956 [May 4, 1955], No. 12892/55. Class 120(2) An appliance to be interposed between a source of roving or yarn and the usual feed rollers of textile machines comprises a stationary guide member provided with a pivoted lever normally retained in position by a pair of passing rovings or yarns but operated by one on the failure of the other to deposit the unbroken roving or yarn in engagement with severing means. A pair of yarns passes through a twizzle 11, and one through each notch 3, 4 in a plate 1, and then normally through a notch 9 in a lever 8 pivoted to the plate 1. If one end ruptures or fails, the tension of the other end causes the lever 8 to pivot and bring the end into contact with the teeth of a comb 10 which severs the yarn and thus prevents further delivery. A slot 13 in the comb 10 permits accurate adjustment. The plate 1 may be of synthetic resin or sheet metal or of wire.

Abstract: 150,049. Cowley, H. W., and Cowley, C. H. May 24, 1919. Mortising.-A mortising-machine comprises two or more chain cutters d mounted on one spindle, or a series of such sets operable simultaneously. The cutter spindles are adjustable laterally along a guide e by means of screws f. The work-table g is raised and lowered by pinions h gearing with racks h<1> thereon and connected to the driving-shaft a through toothed wheels h<2>, k. a shaft k<1>, and either a variable-speed beltpulley k<3> or a reversing-pulley n, the shaft k<1> being connected to either of these pulleys by a clutch o. This clutch is operated by a lever p, a rod p<2>, and a lever s adapted to be actuated either by a treadle or by a rod t<1> which is raised by a tappet t<3> carried by the work-table when this reaches a predetermined height. Reversal of the table-operating mechanism is thus produced automatically when a mortice is completed, and then the machine is stopped by a spring-controlled rod p<3> connected to the lever s and to the belt-fork q. The work 2 is arranged on both sides of a fence 1 extending along the table g between the cutters of each pair, and are clamped thereto by pivoted jaws 3 operated simultaneously by left and right hand screws 5 adapted to be turned individually by handles 6 or together by chain-wheels 7 geared together by means of a chain 8. To allow for wood of varying thickness the chain-wheels may have a small travel between collars 10, Fig. 4, on the screws, so that final adjustment may be made by turning the screws individually. According to the first Provisional Specification screw-and-nut or other mechanism may be used for traversing the worktable, or the work may remain stationary while the cutters are fed to it, and a suction or blowing arrangement may be provided to remove the cuttings.

Title: Improvements in and relating to rope, cord and the like
IPC: D06M11/155
Filed: 1932-05-06
Abstract: Ropes and cords comprising cellulosic fibres, or strands adapted for use in their manufacture, or the fibrous constituents of wire ropes having a core of cellulosic fibre, are rendered more resistant to the action of water by treatment with cuprammonium solution or a solution of ferric chloride, zinc chloride or sulphuric acid.  An example describing the use of cuprammonium solution is given.  The treatment may be applied to the finished rope or cord or to the unspun fibres or to yarns or strands prepared therefrom; when unspun fibres or yarns are treated, they are afterwards worked up in the usual way to ropes or cords or strands adapted for use in their manufacture.  The treatment may be followed by treatment with an alkali-metal soap (cf. Specification 404,330).  The process is particularly useful in the manufacture of rope or cord from sisal.

Title: Improvements relating to the analysis of scientific data
IPC: G06F3/00
Filed: 1952-05-26
Abstract: 732,790. Photo-electric curve reading devices. T.M.M. (RESEARCH), Ltd., BAMFORD, H., and WITCOMBE, L. May 26, 1953 [May 26, 1952], No. 13251/52. Class 40 (3). In apparatus for producing an electrical output in accordance with the ordinate of a trace on a chart, the chart is scanned by a light spot the interception of the spot by the trace being used to produce an output related in frequency or amplitude to the ordinate of the trace on the chart. As shown (Fig. 1) the trace 2 is carried on a continuously moving chart, a light spot produced by a cathode-ray tube 4 and lens 3 oscillating across the chart in a path at right angles to the chart movement. The image of the spot is received by a photo-electric cell 5 which feeds a control signal into a time base generator 6 deflecting the spot. The arrangement is such that the spot moves vertically until it intersects the trace when the sudden reduction of light reaching the photo-cell is used to reset the trace. Thus the rate of resetting is a measure of the amplitude of the trace ordinate while the value which the deflecting time base voltage has reached also represents this ordinate. Circuit (Fig. 2).-Reduction of the light reaching photo-cell 5 by interception of the flying spot by the trace triggers a thyratron 10 discharging condenser 12 (previously charged through resistor 11) through the thyratron. The thyratron cuts off and the condenser recharges, the potential developed at the positive plate of condenser 12 being used to deflect the spot which is thus reset each time the thyratron fires. The repetition frequency of pulses developed across a resistor 16 in the thyratron cathode circuit is a measure of trace amplitude while the current in cathode follower valve 14 depends on the instantaneous value of the time base deflecting voltage. Hence a series of pulses are produced across the cathode resistor of valve 14 and the output obtained through a low-pass filter circuit 15 is a reproduction of the trace. In modifications the spot is arranged to travel the full width of the screen at constant frequency so that an impulse is obtained as the spot passes the trace in both directions, the impulse causing an electronic switch to produce pulses of width inversely proportional to the ordinates. Alternatively impulses may be obtained as the spot passes, first a datum line and then the trace so as to cause the electronic switch to produce pulses of width proportional to the ordinates. Again, the switch may start a pulse when the spot passes the trace in the upward direction and stop it when the spot next crosses the trace, the width of the pulses thus depending on the slope of the trace.

Abstract: 880,529. Writing instruments. TALLON Ltd., and ARENGO, C. G. April 14, 1959 [April 25 1958], No. 13269/58. Class 146(3) A retractable writing instrument, e.g. a ball point pen, comprises a plunger 19 which is movable with the writing unit 12 and which projects from the rear end of the barrel, a spring 27 which urges the writing unit 12 towards retracted position, a push-button 28 slidable laterally in the barrel, interengaging means on the push-button and on the plunger which when engaged retain the writing unit in the projected position, and a second spring 34 which urges the push-button outwards in relation to the barrel. The plunger 19 has a spigot at its forward end which is a friction fit in the rear end of the writing unit 12, and is of rectangular cross-section so as to slide non-rotatably in a correspondingly shaped bore at the rear end of the barrel. The spring 27 is seated at its forward end on a bush 26 fitted in the barrel and at its rear end on a collar 25 on the plunger. Shoulders (not shown) on the plunger engage other shoulders on the interior of the barrel to limit rearward movement thereof. The plunger 19 is slotted at 33, the width of the slot being enlarged at 36 so as to form longitudinal shoulders 37 in the slot. The rear ends of the shoulders 37 are recessed at 39. The push button 28 is radially slidable in a lateral slot 29 in the barrel and has an inner portion which is slidable in the slot 33 in the plunger 19, ears 31 on the push button being engaged in the enlarged portion 36 of the slot 33. Projections 32 on the outer face of the push-button 28 limit inward depression of the button. The spring 34 is a leaf spring attached to the plunger 19 and has a rearwardly extending arm which bears on an inclined face 35 of the push-button 28 to urge the latter outwards. In the retracted position of the writing unit, as shown, the ears 31 on the push button abut against the longitudinal shoulders 37 in the plunger slot 33. When the plunger is depressed it rides over the push button until the ears 31 are snapped into the recesses 39 by the spring 34, whereby the plunger and writing unit are latched in the projected position. The button 28 is pressed inwards to disengage the ears 31 from the recesses 39 and allow retraction of the plunger and writing unit by the spring 27.
