Title: An apparatus and method for joining yarns
IPC: B65H69/04
Filed: 1958-09-30
Abstract: 894,851. Yarns and thread splicing. BLEYLE, M., WEBER, A., WEBER-BLEYLE, E., and GRIESINGER, A., [trading as BLEYLE OHG., WILH.] Sept. 30, 1958 [April 16, 1958], No. 31144/58. Class 120(3) Overlapping yarn ends are joined by forming at least two longitudinally spaced flexible bonds by applications of adhesive. The adhesive may be polyvinylacetate with cyclohexanol or cyclohexanone as plasticiser and methylene chloride or acetone as solvent. The drying time of the adhesive may be extended by using a mixture of solvents boiling at different temperatures. In the operation of the apparatus shown, two combedout ends 64 are lightly intertwisted, placed between grips 15 and 19, and a spring-loaded detent knob, Fig. 5 (not shown) is pressed to allow grips 15 to advance under the action of springs 61 and close with grips 19. A handle 34 is turned clockwise, Fig. 2, to a limit stop (not shown) to operate rack 22 and toothed-segment 32 gearing which raises a slide 21 and thereby withdraws slides 55 to uncover holes 56 through which applicators 25 emerge from a removable tank 6, grip the ends between their tongues, and deposit small quantities of liquid adhesive on the ends in the slots between the grips. Spring 36 is allowed to restore handle 34, slides 55 and applicators 25 to their starting positions. Handle 34 is lifted to operate rack 45, idler 43 and toothedsegment 42 gearing which lowers heaters 51 carried on pivoted levers 50 so that notched nose-pieces 52 engage the yarns to dry and melt the adhesive causing it to permeate the yarn fibres. The adhesive may be polymerized at this stage. Then the handle 34 is lowered to allow heaters 51 to be lifted by restoring springs 65 and enable yarns to harden or set. Finally the yarns are released from the apparatus by pressing handles 58.

Title: Improvements in or relating to gramophones and the like
IPC: G11B3/08
Filed: 1948-12-06
Abstract: 653,236. Supporting gramophone pick-ups. BISHOP, J. Dec. 6, 1948, No. 31525. [Class 40 (ii)] The needle in a gramophone pick-up may be raised from or lowered on to the sound track where desired by means of a lever B which engages an arcuate plate C<SP>1</SP>, secured to the tone arm C, through a rod N. The rod N is movable vertically within limits within a support M and when lowered preparatory to contact of the needle with the record abuts at its lower end against a pivoted lever 5 extending at the other end into the path of a stud 6 on the turn-table. A lever 7 is pivoted at the same point as lever 5 and the two levers engage each other frictionally. A small arm 9 on the end of lever B engages a fork on lever 7. The record is adjusted on the turn-table until the marked portion of the record where reproduction is to commence lies between the stud 6 and the record centre. A distance rod G, as in Specification 589,996, is adjusted so that the needle is over the desired groove and the turn-table rotated until the pin 6 is just in advance of the end of the lever 5. The motor is started and reproduction begins as soon as the stud 6 striking the lever 5 has moved its other end from beneath the rod N. To stop playing, the lever arm B is lowered so that the support M, the rod N and consequently the tone arm are raised. Simultaneously lever 7 is moved towards the turn-table over the surface of lever 5, the latter being prevented from further movement in this direction by a stop 12. The arm B is then raised so that the lever 5 is swung into its original position by frictional engagement with the lever 7. At the same time the rod N passes through a notch 7a in the lever 7 until its end comes to rest on the lever 5.
