Title: Improvements in hole and like internal gauges
IPC: G01B5/08
Filed: 1922-02-02
Abstract: 176,336. Krupp Akt.-Ges., F. Feb. 26, 1921, [Convention date]. Surface and outline gauges.-Relates to internal three-point gauges having feeling-bolts movable at an angle to an adjustable member pressed out by intervening balls acting against a conical part of the adjustable member, and consists in providing means whereby wear on the gauge parts may be corrected and play due to wear eliminated. This is attained by making the feeler-carrying member adjustable relatively to the body of the gauge, and by providing V-grooves for the balls. The invention is described applied to a micrometer screw internal gauge fitted with a pointer to indicate when the feeling-bolts are exerting the correct pressure. The hollow cylindrical body A of the gauge is split longitudinally at one end and has at that end a conical screw-thread a<2> fitted with a nut B so that it can be clamped rigidly to a feeler-carrying member A'. At the other end the body portion has an internal micrometer thread a<3> into which a bush C is screwed,. the bush having a graduated thimble D which surrounds the body and registers with a scale a<4> on it, and being rotatable around a second bush G, to the right-hand end of which is screwed the casing H of a dial indicator. Upon the bush G is slidable in the casing A a collar g<1> prevented from rotating by a groove g<2> taking a key a<5> fixed to the casing. The enlarged end k<1> of a central bolt K is held against the bottom of the casing H by a spring P within the bush G, and a spring plunger M connected to the pointer N of the dial indicator bears against this end of the bolt, the other end carrying cone k<3> bearing against three balls Q which in turn bear against the feeling- bolts T. The balls are pressed by the spring P against V-grooves a<6>, Fig. 5, the other side a<8> of the guides being semicylindrical. In use, the feeling bolts are inserted into a hole and the thimble D rotated, causing the bolt K to move forward and force out the feeling-bolts. As soon as contact is made with the sides of the hole further rotation of the thimble causes the casing H to move relatively to the bolt, compressing the spring P and displacing the bolt M and pointer N of the dial indicator; when this indicates zero the proper pressure is being exerted by the feeling-bolts and the reading is taken. Wear that occurs on the faces a' of the V-grooves a<6> does not cause slackness, and error due to this wear may be corrected by setting the thimble to the dimensions of a calibrating ring while the gauge is inserted in the ring, loosening the nut B, and screwing the part A<1> further into the part A until the pointer indicates zero, then tightening the nut B.

Title: A process for the production of activated carbon
IPC: C01B32/336
Filed: 1928-02-01
Abstract: 310,908. Williams, W. M., Claytor, R. S., Fry, Sir J. P., and Harper. A. R. Feb. 1, 1928. Carbon.-Active carbon is produced from bituminous coal. or other carbonaceous material which will evolve combustible gases when heated, by injecting the powdered material with a limited quantity of air into a retort at a temperature of about 800‹ C. or over, e.g. 800-1000‹ C., the material being partially burnt and being maintained in the products of combustion until it is activated. The retort may be of elongated form and circular cross-section and may be vertically or horizontally disposed. The material which may be coal dust or other cheap material may be injected tangentially. The walls of the retort are preferably lined with magnesite or other refractory material promoting surface combustion. Acid may be added to the raw material or directly to the retort to render the atmosphere acid during the activation. The results obtained may be controlled by varying the air, combustible gas and the powder supplies, and the pressure within the retort. To obtain more intense combustion the air supply may be preheated and a second air blast may be introduced into the retort at a point below the first inlet. A steam ejector may be provided to withdraw the treated carbon. In an example. the powdered material is fed from a hopper 14 by a screw conveyer 15 into a tube 18 from which it is injected by compressed air, supplied through a pipe 19, through a pipe 13 tangentially into the retort 10. Combustible gas may be introduced through a pipe 20. The retort comprises a metal casing 12 lined with fire- .brick 11. Acid may be introduced through a pipe 21 and a regulating cock 22. The activated carbon is withdrawn through an opening 23 and is distributed by arose 24 in water in a tank 27 from which it is removed by suction through a pipe 25 to a filter press or other separating device. The residual gas which consists largely of carbonic oxide escapes through a pipe 26. The carbon may be cooled or quenched as soon as activation is completed by introducing a water spray at a suitable point 28 in the retort. In one form, the coal dust is introduced with air and coal gas into the retort which has previously been heated to bright red heat by burning coal gas therein. The residual carbon is washed in dilute sulphuric acid. dried and re-treated. In another form in which the activation is effected in one operation, hydrochloric acid is introduced directly into the retort and no combustible gas is used after the preliminary heating. Specifications 206,862, 228,582, and 228,954 are referred to. The Provisional Specification describes a preliminary carbonization step in which when the retort is sufficiently heated the supply of combustible gas is shut off.

Title: Thread tensioning device in sewing machines
IPC: D05B47/00
Filed: 1959-01-29
Abstract: 863,696. Sewing machines. SINGER MANUFACTURING CO. Jan. 29, 1959 [Feb. 14, 1958], No. 3300/59. Class 112 A sewing machine comprises a rotary take-up, a thread-tensioning unit disposed under the takeup, a check spring anchored to the tensioning unit and having a looped extremity for engaging the thread extending between the tensioning unit and the take-up, a thread guide for engaging the thread between the tensioning unit and the take-up, and a check spring guard member secured to the tensioning unit and having a finger extending across the looped extremity of the check spring at a point disposed between the thread guide and the path of the periphery of the take-up. A thread-tensioning unit comprises a stud 30 carrying a hollow collar 35 formed with a peripheral groove 36 fixable by means of a set screw in the head 10 of a sewing machine. A thread-engaging wheel 49, disposed between friction washers 48, 51, is journalled on stud 30. Washer 48 abuts a guard disc 42 keyed to roller 35. Washer 51 abuts a pressure disc 52 slidably but non-rotatably mounted on stud 30. A spring 55, interposed between a nut 56 and the disc 52, applies pressure to the latter. Disc 42 is formed over half its periphery with an axiallyextending flange 45. A threading slot 46 extends peripherally from one end of flange 45 at the base thereof, and a finger 47 extends axially from the other end of flange 45. A check spring 22, keyed to stud 30 within collar 35, has a portion 59 which extends radially through a slot 38 in collar 35 and is bent into a loop 60 which extends across the periphery of the guard disc 42 in the gap between the ends of flange 45, the free end 61 of loop 60 being bent to extend inwardly beyond the outer face of disc 52. The thread tensioning unit is used in conjunction with a thread guide 19 carried on the presser bar 17, and a rotary take-up 13 journalled at 12 in the head 10 of the sewing machine. The tensioning unit is located immediately under the take-up and in a position such that stud 30, the guard finger 47 and the pivot 12 are substantially aligned. In threading the tensioner, the thread is drawn through the slot 46 which directs the thread on to the peripheral channel in the wheel 49. The thread is then looped around the latter till its free end assumes the position A, when the thread is disposed under both the finger 47 and the spring 61. The thread is then moved in the reverse direction, when it is guided by the flange 45 over the end 61 to enter the loop 60. The thread is then passed downwardly through the guide 19, and is then moved reversely to the position B, prior to being threaded through the take-up 13. In position B the thread extends over the finger 47, and the latter thus prevents the thread from re-entering the check spring loop 60.
