Filed: 1964-06-19
Abstract: 1,020,253. Coating pipes internally. J. J. HEILKER. June 19, 1964, No. 25443/64. Heading B2B. An internal coating of synthetic resin is produced in a pipe by spasmodically blowing or drawing through the preheated pipe airborne powdered synthetic resin material. One end of a flanged preheated pipe 11 is connected through a hole in a plate 9, a member 7 and valve 6 to a vessel 1 containing a fluidized bed 28 of the coating material while the other end is connected through pipes 14, 17 and valve 18 to a vacuum and dust collection box 20. With valve 6 closed valve 18 is opened reducing the pressure in the pipe 11; valve 6 is then suddenly opened while valve 18 is closed thus causing coating material to whirl into and through the pipe 11. An additional vaned member 7 may serve to impart the whirling motion to the air and powder mixture. The procedure is repeated several times to deposit a uniform coating on the walls of the pipe. Coating materials specified include superpolyamides, chlorinated polyesters and nylon. The pipe is heated to between 300 ‹C. and 350 ‹C. by means of an oven, by induction heating or by infra red ray treatment.

Abstract: 1442529 Magnetic printing; selective printing RAYTHEON CO 7 June 1974 [22 June 1973] 25465/74 Headings B6C and B6F Multicolour printing is achieved by magnetizing a magnetizable member 101, Fig. 1 with different states of magnetization corresponding to the different colours, and applying differently coloured tones each of which has correspondingly different magnetic characteristics. In the embodiment, the magnetism is applied by A.C. energized electromagnets, and the state of magnestism is affected by change in A.C. frequency. The recording head applies the magnetic pattern in the chosen state, tone is supplied at 119, untrasonic transducer and roughened surface 106 are effective to enhance the image by shaking off the loosely held toner lying in areas not appropriate to its characteristics, excess toner falls off into 111, and is removed by ultrasonic transducer 109, and the remaining toner is transferred to preheated paper 113 which is then heated at 117 to fuse the image. Air doctor 121 removes any non- transferred toner, and erasing head 123 removes the magnetic image and leaves the member 101 uniformly magnetized. The magnetic pattern may be characters. Selective printing.-Polepieces 509, 512 (Fig. 5) are electromagnetically actuated by coils 508 to generate field in gaps 513 through which belt 101 is passed. Each pole piece is energized by a character pattern signal from 503 to which is superimposed an A.C. frequency 510 or 511 selected by switches 506.

Title: An improvement in or relating to textile finishing or like machines
IPC: D06C29/00
Filed: 1922-09-21
Abstract: 205,308. Shaw, L. E. Sept. 21, 1922. Cropping.-Fabric g passing through a cutting or cropping or like machine is automatically tensioned by a device comprising at each side a T-shaped lever, pivoted about a fixed bar a and carrying rods d, i and a weighted roller f over which the cloth passes to the usual fixed rail h and thence to the cutting bed. The lever may be a two armed lever only, in which case there is no rod i and the cloth takes the path at the beginning as shown by the chain-dotted line g. Any abnormal pull on the fabric causes the levers to pivot about the bar a and relieves the pressure of the weighted roller, while undue slackness permits the weighted roller to fall, thus increasing the tension. Lugs c<4> may be formed on the levers for attaching extra weights.

A work holder comprises devices 1, 2 connected in use by a workpiece on an axis 5, and indexing means including a member 3 having a number of flat faces corresponding to the number of indexed positions required and a wedge 18 connected to a one-way device 21 which enables the wedge to be moved against one of the faces when the workpiece has been indexed to a required position. In operation, pneumatic means are operated to move a rack 7 and rotate a shaft 9. The shaft rotates the device 2 through the one-way clutch 21 and gearing 24, 4, the device 1 being simultaneously rotated by its connection to the work. At the same time, the shaft 9 rotates segmental gearing 16 to withdraw the wedge 18 from the member 3 on the device 1 to permit the rotation thereof. The movement of the rod 6 is halted by a stop 11 engaging a gear 8. The member 3 and hence the work are held temporarily by a plunger 26 before the rod 6 is reversed to re-engage the wedge. The wedge completes the precise indexing of the work and locks it in place.
