Abstract: 680,464. Lap-forming apparatus; delivery and discharge apparatus for scutching and like machines; roller arrangements and stop motions for spinning &c. machines. T.M.M. (RESEARCH), Ltd., and SZALOKI, L. Dec. 29, 1950 [Jan. 23, 1950], No. 1714/50. Classes 120(i) and 120(ii) In the operation of a lap-roll forming apparatus such as may be employed in conjunction with a scutching machine, a continuous lap 20 is fed through calender rolls 11, 12, 13, 14, 15, and wound on a mandril 48 loosely and rotatably held within a loop 9 formed in a travelling belt 1 driven by rollers 2, 3: the increase in size of the loop 9 required to accommodate the roll, as convolutions are added thereto, is automatically supplied by a loop 65 passing beneath a weighted roller 63 the tensioning effect of which may be assisted by a spring anchorage 64 so that the pressure on the roll during its formation is uniform. When the size of the roll is deemed sufficient or as determined by a length-measuring mechanism, the lap 20 is automatically severed and an arm 26 is oscillated whereby doffiing roller arms 10 are swung outwardly so tightening the belt and ejecting the roll, as shown in Fig. 4: simultaneously therewith, loading arms 51 are pivoted by means of a lever-linkage 62, 61, 60, into a position in which solenoid-operated plungers, controlled by a switch 511, engage the lowermost mandril, in a magazine 47, and then the arms 10, in returning to their initial position restore the loop 9 by pressing the new mandril against the belt between the rollers 2, 3. These movements are initiated by mechanism comprising a shaft 21 which may be clutched by means of an electromagnetically actuated rolling- key device, Figs. 6 and 7 (not shown), to a sprocket 19: it carries a crank 24 bearing a cross-head 25 which slides on the arm 26 which is fixed to a gear 27 rotatably mounted on a stud 28 and in mesh with a gear 29 fixed to a rotatable stud 30 on which the arm 10 is mounted. The rollers 12 and 14 are weighted by an elastic link 121 one extremity of which is attached to one end of a lever 122 which bears upon the arbor of the roller 12 and the other end of which pushes upwardly against a lever 123 fulcrummed against a fixed abutment 124, with its other extremity bearing upon the arbor of the roller 14. The rollers 11-15 are geared together, the roller 11 being driven through a chain 16 and the rotation of the roller 15 being utilized to drive a sprocket 17 on the roller 2 through a chain 18 which also drives the sprocket 19. Automatic lap-severing apparatus, Figs. 9, 10, 11 (not shown), may comprise a freewheel and rolling-key clutch device, or (if the roll 15 has a separate chain drive) a magnetically operated dog-clutch device for suddenly accelerating the belt 1 or momentarily stopping the web-feeding mechanism, or a severing comb may be used.

Filed: 1965-01-15
Abstract: 1,085,862. Superconductive temperaturesensitive device. INTERNATIONAL BUSINESS MACHINES CORPORATION. Jan. 15, 1965, No. 1795/65. Heading H1K. A temperature-sensitive device comprises two contiguous layers of different electricallyconductive materials, at least one of the materials being capable of exhibiting superconductivity, the thickness of the layers not being uniform along the length of the device. A copper layer 2 is overlayed with a lead wedge 1, the copper layer being wider than the lead to prevent short-circuiting during resistance measuring. The layer 1 need not be wedge-shaped but may be stepped (Fig. 4, not shown), thus giving only two specific temperature values, alternatively the lower layer 2 may be wedge-shaped whilst the upper layer 1 is of constant thickness. If both layers 1 and 2 are super-conducting material, then they must have different critical temperatures.
