Title: Improvements in machines for testing the hardness of materials
IPC: G01N3/44
Filed: 1930-08-21
Abstract: 353,729. Testing hardness of materials. AVERY, Ltd., W. & T. and HANCOX, A. H., Soho Foundry, Birming- ham. Aug. 21, 1930, No. 24963. [Class 106 (ii).] Comprises a machine for testing by penetration wherein the penetrating element is mounted on or connected to a slide which has pivotal connection to the indicator and to the lever system of the machine said system incorporating a loadable member for applying the predetermined load to the penetrating element, and means co-operating with a damping device for applying and releasing the load without shock. A base 1 has a boss 1a within which is mounted a screw 2 adapted to be raised and lowered without rotation by a handwheel 5. The base also supports two uprights 6 from which projects a crosshead 7 in the end of which is mounted by parallel links 9 a slide 8 carrying the indenting member 10. A lever 14 rests by a knife-edge 14a on the slide 8 and carries a knifeedge 14b on which rests a shackle 16a pivoted to one end of a rod 16 the other end of which is pivoted to a shackle 16b engaging a knife-edge 8b on the part 7. The latter carries a dial indicator 13 the actuating rack of which is connected by shackle and knife-edge to a lever 11 supported by a knifeedge on the slide 8 and connected to the crosshead by a link 12 and knife-edges. From a knifeedge at the end of the long arm of the lever 14 depends a shackle 19 ending in an enlargement 19a moving inside a hollow rod 20b rising from the weight 20 and on which other loading weights may be placed. The weight 20 rests normally on a platform 22 the stem 23 of which passes through a support 24a and into a dashpot 25. In use, the specimen 4 is placed on the platform 3 and the screw 2 moved upwards until the specimen engages the member 10. Further movement raises the slide to disengage the shoulder 8a from the shoulder 7a an indication appearing in the gauge. An initial load corresponding to the weight of the slide 8 and associated parts is thus applied. The gauge is then zeroized, and a stop 29 released from the support 24 which is moved down by rack-and-pinion gear until the part 20c engages the enlargement 19a. On further movement the predetermined load is applied to the lever 14.

Abstract: 749,709. Drag device. BOYD, Ltd., J. & T. July 29, 1954 [Sept. 11, 1953], No. 25134/53. Class 120 (2). A drag arrangement for flyer textile spinning or twisting machines of the type in which a dead spindle supports a bobbin and a carrier tube which is rotatable with the bobbin when the bobbin is driven by pull of the thread includes a centrifugal drag device arranged for frictional engagement with a stationary surface of the dead spindle in such wise that a drag is maintained on the tube when the tube is stationary or is only slowly rotating, but is reduced or removed as the speed of the tube increases. As shown, bobbin 12 is carried on a tube 11 mounted on a dead spindle 10. Attached to the lower end of tube 11 is a hollow boss or ring 14 on the outside periphery of which there are attached, at 16, two blade spring members 15. The free ends of members 15 have attached thereto radial pins 17 entering through holes 18 in the ring 14 and bearing with their inner ends 19 on a part 20 of the spindle 10. When the tube 11 and the ring 14 revolve the pins 17 move away from the spindle under the influence of centrifugal force thus relieving the drag effect on the tube 11.

Rapid variation in tension is taken up by the bar 42, the effective length of which is adjustable by a hand wheel 60. The tension is adjusted by adjusting the torque of the motor 52. There is also provided a selsyn 76 coupled to a tachometer 74, the selsyn output voltage varying with the rotational position of a shaft 80 and the tachometer output voltage varying with the rate of change of the shaft position. The selsyn and tachometer are electrically connected to the motor 10 to change the back-tension torque exerted on the strip.

The prepolymer is defined as having an inherent viscosity of 0À045 to 0À05 (2À5 g./100 c.c. dimethyl formamide at 25‹ C.) and comprising the reaction product of a tetraester of benzophenone tetracarboxylic acid with 3,3<SP>1</SP>,4,4<SP>1</SP> - tetraaminobenzophenone and being soluble in dioxan and chloroform. It may be formed by heating the reactants at up to 215‹ C. for up to 50 minutes then terminating the reaction. The conductor may be a mono- or multifilament metal wire. A solution of the prepolymer may be applied to an insulating film, e.g. polyimide tape, and the coating dried and heat set for 2¢ minutes at 250‹ C. The coated tape is then wrapped around the conductor and cured, e.g. for 4 to 5 hours at 550‹ to 650‹ C. In examples the prepolymer is prepared from the tetraethyl ester. A 28 wt. per cent solution of the prepolymer (inherent viscosity 0À56) is coated on a 1 mil. x # inch polyimide tape which is passed therethrough, dried and heat-set. It is then double or treble-wrapped with 50% overlap and reversal of direction on a silver plated multifilament copper wire while heated at 600Œ100‹ F. in the vicinity of the wrapping point. The wrapped wire is then passed through a curing oven at 600Œ50‹ F. and post-cured in an argon atmosphere for 4 to 8 hours at 600‹ F. Other methods of applying the coating are generally described, e.g. a melt or solution may be applied directly to a bare or wrapped wire in one or more applications with preliminary drying and curing of each coating as applied or of all the coatings in a subsequent step.
