Title: Conformable non-woven bandage
IPC: D04H1/70
Filed: 1973-10-29
Abstract: 1382789 Non-woven fabric; corrugating webs KENDALL CO 29 Oct 1973 [24 Nov 1972] 50248/73 Headings D1R and D1S A conformable bandage material comprises a non-woven strip of entangled cellulosic fibres having a repeating series of wave-like undulations each of which extend across the width of the strip, the peaks and valleys 12 being dense compared to the side slopes 14 which have a lower fibre density and greater extensibility. To make the bandage, superposed carded cotton webs, in each of which the fibres are predominently orientated in the longitudinal direction, are continuously fed without tension onto the surface of a bath of 8-30% aqueous NaOH, floated across the surface of the bath, removed on a conveyor, washed with water, sprayed with dilute acetic acid, and calendered and dried on heated rotary drums, in an oven or under infra-red lamps. The alkaline treatment swells the fibres producing curling kinking looping and twisting of the fibres to yield a shrunk, felt-like sheet. Preferably the reduction in area is less than 40%. The dry sheet is then stretched to increase its area by 8 to 45% by transferring from one roll to a faster rotating roll, by passing it through a button breaker or between rotating gears, by drawing it over knife edges or bars of small diameter or by tentering. The clingability, thickness, softness and tensile strength in the direction of stretching are thereby increased. The sheet is mechanically compressively shrunk in the longitudinal direction to produce the fabric shown by the method of U.S.A. Specification 2765513. The apparatus comprises a nip formed by a resilient surfaced faster rotating feeding roll and a second slower rotating roll. An indentor shoe presses incoming fabric against the feeding roll along a line spaced a short distance in front of the nip. Hence the fabric is positively fed up to and beyond the discharge edge of the indentor blade and then decelerated by engagement with the second roll, whose surface has a higher coefficient of friction than the feeding roll, e.g. an abrasive coating or soft rubber surface.  The fabric weighs 40 to 120 g/sq. yd., has 8 to 16 convolutions/inch, an elongation at break of 50 to 70% and is shrunk by 10 to 40% during compaction.

Abstract: 1378239 Delayed shutter release ASAHI KOGAKU KOGYO KK 1 Nov 1972 [28 June 1972] 50322/72 Heading G2A A delayed shutter release mechanism is cocked by manually rotating anti-clockwise a lever 11 having a stopper pin 13 which causes rotation of a stopper plate 9, timer axle 8/15 and cam plate 17. The timer mechanism is released by manually rotating anti-clockwise a starter ring 5 having a starter pin 7 and release pin 6 until starter pin 7 re-engages a recess 11a in lever 11 and release pin 6 rotates anchor arresting lever 28 against anti-clockwise bias to free star wheel 32. Timer axle 8/15  and cam plate 17 then rotate clockwise, cam surface 17c moving anti-clockwise cam surface 22c of U-shaped actuating lever 22 and causing arm 22a of lever 22 to move clockwise pin 21 of anti-clockwise biased shutter actuating plate 19. Cocking lever 11, which also rotates clockwise, finally returns starter ring 5 to its original position, cam surface 17a simultaneously taking over the function of release pin 6. The timer mechanism may be interrupted by manually returning cocking lever 11, causing return of starter ring 5 but not cam plate 17 (lever 11 being connected to timer axle 8/15 via a friction spring).

Measuring capacitor 13, 15 and a compensating capacitor 14, 16 for cancelling changes in capacitance due to movement of plate 13 determine the frequency of an oscillator (not shown). The beat frequency between this oscillator and another is converted to a D.C. signal which is combined with a D.C. signal from the pneumatic device 10 and fed to a thyristor to control the delivery device of the material. The positions of capacitor plates 15 and 16 and the position of pneumatic device 10 are adjustable relative to the frame 17.

[Also in Division F2] Apparatus in which a massive body 3, e.g. a code combination bar, or locking bar of a teleprinter, is given a translational motion between two fixed positions, is provided with latching means at each of the terminal positions. The body 3 carrying an armature 4 is mounted on a resilient cantilever 1 to oscillate between electromagnets 5, 6. On energizing coil 5, the body 3 is displaced towards the coil 5 and, while the coil remains energized, is held in this first terminal position. On de-energizing coil 5, the energy stored in the flexed spring 1 carries the body 3 to the second terminal position, where it may be held by energizing coil 6. In a second embodiment, the body (7) is pivotally connected by lever arms (8,8) to a frame member (9).. Restoring springs (10, 10) connect the arms (8, 8) to a point on the frame. The body carries an armature (11) and by selectively energizing one of three windings (19, 20, 21) the body is moved as before.

A load measuring arrangement comprises a load cell 5 and a pressure member 4 which, on lateral displacement of load applying member 3, causes the point of application of the force to the load cell to shift laterally and the direction of force application to change, the increase in sensitivity of the load cell due to this lateral shift being compensated for by a decrease in sensitivity due to the change in direction. The pressure member 4 may instead be arranged between the load cell and its support, or a pressure member may be provided at each side of the load cell, Fig. 7 (not shown). Alternatively the load cell may be incorporated in a pressure member, Fig. 8 (not shown). The pressure member may have curved surfaces 6 co-operating with flat surfaces on the load cell and force applying member 3, flat surfaces co-operating with curved surfaces, or a flat and a curved surface co-operating with a curved and a flat surface respectively.

In the arrangement shown, a further roll 10 opposes roll 7, and rolls 8 and 10 are supported on a frame 14 mounted on the discs by shaft 15. The tube is driven by a feed in the body 2 of the machine, and the position of roll 9, and hence the bend curvature is controlled by links 21, 22, so that a tube may contain bends of various curvatures and straight portions. The tube may be rotated to alter the plane of bending, and this rotation may be coupled to the tube feed so that a helix is produced.

This arrangement prevents the occurrence of stresses, due to differences in thermal expansion between the housing 10 and cage 12 which would occur if the two were rigidly secured together. Rotation of the set screw 28 allows adjustment of the position of the cage 12 and thus its centre of gravity with respect to the housing 10. The cage 12 and carriers 16 may be sealed and the cage may contain a flotation liquid for the carriers. The housing 10 is preferably gas-filled and a membrane 34 seals the socket 26 to prevent leakage of gas. A spring 30 round the socket 24 bears on the cage 12 to keep it in place during acceleration of the vehicle in which the apparatus is mounted. As an alternative to the spring 30, the set screw 28 may be anchored to the pin 22, e. g. by providing a head on the set screw engaging into a transverse opening in the pin or by providing a screw threaded axial bore in the bottom end of the pin into which is screwed the upper end of the set screw. One or both of the pins 20, 22 may have necked portions to provide lateral flexibility and these may have cylindrical or elliptical cross-sections, the latter providing different spring constants in the directions of the images and minor axes of the ellipse.
