Title: Tube bending machine control
Inventor: CHOCIAN MARIAN PIOTR
IPC: B21D7/12
Filed: 1971-04-05
Abstract: 1291790 Angular bending MC MACHINES Ltd 5 April 1971 8702/71 Heading B3E [Also in Division F2] A rotary control valve for a tube bending machine has a fixed body 128 to which are connected an inlet 130 and a plurality of circumferentially spaced outlets 78. Mounted within the body is a rotary element 132 connected to a selector 138. Annular grooves 142, 144 and passage 146 in the element and passage 148 in the selector communicate the inlet to the selected one of the outlets 78. Circumferentially spaced through holes in the selector communicate the remainder of the outlets to atmosphere. In use the selector is connected to the turret of the machine and each outlet is connected to a respective one of a plurality of piston-cylinders 76 which operate locking heads 72. Each of the latter co-operate with a notch in a disc 70 mounted on a rotary shaft 68 on a carriage 100 which runs on wheels 92 along rails 26, 28 that can be moved laterally by rack and pinions 32, 34. The carriage carries a tube gripping collet 98 which is actuated by piston-cylinder 106, 112 and is rotatable with the shaft 68. Each disc 70 is diametrically split and is lockable on the shaft 68 by a screw extending across the split. Prior to bending each disc is locked on the shaft in a predetermined angular position which represents a required angle of plane of bending and is measured by a scale and vernier 120, 124. After the tube has been gripped by the collet 98 the carriage is moved so that a spring-loaded non-return detent 82 rides over a first step 40 along the side of the rails and abuts its rear surface. The turret is then rotated to cause the valve to admit pressure to the first piston cylinder. The shaft 68 is then rotated until the locking head 72 enters the notch in the first disc 70. The tube is now in the required plane for bending. After bending the carriage is moved so that the detent 82 abuts the second stop 40 and the turret and shaft 68 are respectively rotated to position the tube in the second required plane for bending as before. Abutment of the carriage with an end stop 44 automatically returns the carriage. The valve and control system may be used to cause locking heads to hold the carriage in predetermined longitudinal positions and/or to automatically control the angle of bend.

Abstract: 548,842. Valve amplifying circuits BRITISH THOMSON-HOUSTON CO., Ltd. July 10, 1941, No. 8739. Convention date, July 12, 1940. [Class 40 (v)] In a multi-stage amplifier having a common source of power, a filter is connected between each adjacent pair of electron discharge devices, the filters being thus cascade connected and the source of power is connected to an intermediate point along the cascade-connected filters and an additional filter is located in the connection to each stage from the cascade-connected filters. The Figure shows an amplifier having stages 10... 15 associated with filters comprising members 24 ... 48 and the supply 23 connected at an intermediate point, preferably a central point as by dividing resistances 24, 29 if an odd number of stages is used. In this way more effective decoupling is obtained particularly between stages at widely differing power levels and radiation from the high tension source is avoided which might occur if this were directly connected to the output stage.

Title: Improvements in or relating to data storage arrangements
Inventor: KILBURN TOM
IPC: G06F12/06
Filed: 1960-03-16
Abstract: 976, 504. Electric digital-data-storage. NATIONAL RESEARCH DEVELOPMENT CORPORATION. March 14, 1961 [March 16, 1960], No. 9301/60. Heading G4C. A data storage arrangement comprises a plurality of separate blocks of data word storage elements and is characterized by address selection control means arranged so that successive address numbers cause selection of word storage locations which are in different ones of said blocks. As described, a data store comprises four blocks in the form of magnetic core matrices A-D, each block storing four data words of 40 digits each. The sixteen locations in the matrices have address numbers 0, 1, 2,..., 15 in binary code, locations 0, 4, 8, 12 being in the matrix A, locations 1, 5, 9, 13 in B and so on. To address a chosen location its binarycoded address is staticised by a four-stage staticisor 10, the outputs of which are connected by an arrangement of AND gates 12a-12d, 13a-13d,..., 17a-17d to the inputs of the matrices A-D in such a way that an output is produced on that one of leads 18 corresponding to the address in the staticisor 10. Normally, locations are addressed in sequential order, but in case it is required to obtain access successively to two storage locations in the same matrix, a monostable flip-flop 20 is connected to all the leads 18 for the matrix A, the output of the flip-flop 20 being connected via a delay 22 to an AND gate 23. An output is thus provided on a lead 24 for a chosen period, which output may be arranged as an inhibiting signal to prevent the next address selection taking place in the matrix A until an appropriate recovery time for the matrix A has elapsed. A similar arrangement is provided for the matrices B, C, D. In a modification (Fig. 2, not shown), locations 0-7 are arranged alternately in matrices A, B and locations 8-15 are arranged alternately in matrices C, D.

Title: Improvements in circular knitting machines and method of operating same
IPC: D04B1/18
Filed: 1937-04-01
Abstract: 476,534. Knitting-machines. SCOTT & WILLIAMS, Inc. April 1, 1937, No. 9312. Convention date, April 1, 1936. [Class 74 (ii)] For tying-in an elastic or other yarn, e.g. in the upper end of a half-hose, a yarn finger 128 of a circular machine is withdrawn from feeding position without cutting the yarn, and then at a subsequent course is reintroduced at substantially the needle where it was withdrawn. All the needles n are lowered until they pass below the yarn finger 128, the finger is moved to operative position outside the needle circle, and the needles receiving the yarn are raised so that their hook ends are above the yarn finger end just after they pass the finger. In the arrangement described, the shorter-butted heel needles are divided into two sets having different lengths of butts n<1>, n<2>, and the longerbutted instep needles also are divided into two sets with butts n<3>, n<4> of different length. The butts n<2>, n<3>, n<4> are engaged by a lowering cam 383; and after passing the cam 383, the longest butts n<4> only are engaged by a raising cam 384. A cam 385 lowers the needles having butts n<1> to the new level of the longest butted needles. The shortest and longest butted needles which are those receiving the weft yarn y<1> are therefore selected for subsequent operation by a raising cam 388 which lifts these needles after they have passed the finger 128. A lowering cam 389 acts upon the butts of all the needles prior to the clearing of the needles to lower all the needles with the elastic or other weft yarn in their hooks before the needles are raised to take the knitted inelastic yarn. The method of operating the sinkers and the needles for the purpose of measuring off the weft yarn is described in Specification 454,078. A more pronounced ribbed appearance is obtained by causing the sinkers to slacken the wales on either side of the needles which tie in the weft, and mechanism for this purpose is described in U.S.A. Specification 1,189,220. British Specification 12722/13, [Class 74 (ii)], also is referred to.

Title: Improvements in taping machine
IPC: A43D43/06
Filed: 1930-03-24
Abstract: 342,205. Affixing tape to sheet material. EATON, H. M., 42, Walker Road, Swampscott, and EXCEL TAPING MACHINE CO., 130, Eastern Avenue, Lynn, both in Massachusetts, U.S.A. March 24, 1930, No. 9367. [Class 73.] A machine for pressing adhesive tape into engagement with sheet material, such as shoe upper parts, comprises a pair of presser rolls between which the sheets pass, and a support for a roll of tape arranged to direct a run into frictional engagement with a considerable peripheral portion of one of the rolls, a guide receiving the tape from the peripheral portion and directing it to the bite of the rolls, where it is united with the other sheet. The tape 11, Fig. 19, is led through a damping device 20 which removes any trace of adhesive from the uncoated side, to a roller 16 mounted on a fixed axis, whence it passes round the periphery of the lower pressing roll 15 to a roller 17 mounted on a spring-influenced, pivoted arm 18, and thence to the feeding member. The latter, as shown in Fig. 20, comprises a spring- mounted, pivoted member 90 having a serrated edge 91 which maintains the tape in contact with the roll 15, and from which the tape passes through a slit in a member 71 and then to the bite between the rolls 14, 15. The members 90, 71 are mounted on the end of a swinging plate 70 which is operated by a pedal-actuated sector 105. At its other end the plate 70 is provided with a spring-controlled dog 92 which engages a striker 101 to project a knife 99a riding in a fixed, tubular casing 96 to cut the tape. During the cutting movement the swing- ing of the plate 70 moves the guiding members out of the path of the knife. Detachably secured to the member 71 is the terminal element of the tape guide 77 which may consist of a member the overturned end of which is slotted. If the tape is to be applied to the turned-back portions of the seams of satin shoe uppers a guide such as shown in Figs. 11 and 12 is used which comprises a base member 212 having a slot 214 through which the tape passes, and a central sloping ridge 216 along which the seam is fed, the edges of the seam being turned back by flared portions 218. With this form a fixed spring presser is provided which cooperates with the flat portion 241 of the guide. In another form for other seamed articles, the ridge 216 is replaced by a longitudinal depression guiding the seam. The rolls 14, 15 are removable, and may be transversely concave and convex respectively; they are mounted on the base 1, Fig. 1, and head 2 which is pivoted to the base at one end and can be given an adjustable vertical vibrating motion with respect thereto by means of a pivoted member 64, adjustable by a screw 68 and engaging a polygonal cam 60 on a shaft 37. This vibrating motion is imparted to the head when the tape is applied round curved edges. The driving mechanism comprises cross-shafts 42, 51, in the base and head respectively, driven from a belt pulley 36. An edge guide may be provided for applying the tape to the edges of sheet material.
