Title: Improvements in, or relating to the manufacture of artificial threads or filaments
IPC: D01D5/00
Filed: 1928-07-05
Abstract: 320,106. British Celanese, Ltd., and Taylor, W. I. July 5, 1928. Apparatus for making filaments.-The starting up of spinning jets in the manufacture of artificial threads or filaments, more particularly by the dry spinning process, is effected by applying a vacuum to the jet until uninterrupted extrusion is obtained. In the form of apparatus shown in Fig. 1, an annular member 3, having a central aperture 4 of a size to accommodate, the jet face 5, is provided on one side with a rubber or like ring 6 adapted to fit against the part 7 of the jet surrounding the face 5 and on the other side with an annular recess, provided with a rubber or like ring 9, into which is fitted one end of a glass or other transparent cylinder 10. The other end of this cylinder is similarly fitted into an annular recess 11 in a member 12 provided with a rubber or like seating ring 13. Connection is made with the vacuum by means of the member 14, which communicates through passages 15 and 16 with the interior of the cylinder. The two members 3 and 12 &re held against the ends of the cylinder 10 by means of a nut or ring 17, which screws on to the upper end of the member 12 and is connected with the member 3 by a number of metal strips 18, which may be screwed, sweated, or otherwise secured to the members, so that when the nut or ring 17 is screwed on to the member 12, the cylinder 10 is pressed firmly into the recesses 8 and 11 and forms an air-tight connection with the rings 9 and 13. In the form of apparatus shown in Fig. 2, a glass or other transparent vessel 19 is provided with a vacuum connection 20 and a bulged mouth 22, over which a rubber or like ring 21 is sprung, or alternatively a ring may be fitted to the mouth of the vessel 19 by providing the open end of the vessel with a cap by which the ring is carried. These devices are placed in position by hand or in any other manner, so that the rings 6 or 21 form air-tight joints, around the jets 5. The suction applied to the devices is usually sufficient to hold them in position. The devices are preferably connected with the vacuum by flexible tubing, so that one device may serve for a number of jets, but a device may be fitted for each jet. In operation, the jet is screwed by a nut 23 on to the pipe, 24 connected to the supply of spinning solution and the jet face 5 is wiped with a solvent-soared fabric. When solution appears through the holes, the vacuum device is applied to the jet and is retained in position by the suction, which is applied until all the holes are observed to be free. Thereupon, the device is removed to allow the filaments to be extruded into the atmosphere of the spinning cell. The devices illustrated are shown applied to jets of the perforated disc type, but jets of other type, e.g. line-type jets may be started by devices having appropriately shaped. orifices 4 and rings 6 or 21.

Title: Method and apparatus for grinding a workpiece
IPC: B24B49/00
Filed: 1975-05-09
Abstract: 1464337 Grinding SEIKO SEIKI KK 9 May 1975 [16 May 1974 10 May 1974] 19608/75 Heading B3D [Also in Divisions H2 and G3] A method of grinding a workpiece W comprises maintaining a grinding wheel 10, mounted on a spindle 9, and the workpiece W in pressure contact with each other which effecting relative rotation therebetween, feeding the workpiece and the grinding wheel relatively towards each other, and varying the relative rotational speed of the workpiece and grinding wheel. In one embodiment of apparatus for carrying out the method, the workpiece W, the bore of which is to be ground, is mounted on a spindle 2 driven by a motor 4 and carried by an infeed table 3 connected to an infeed device 5 and motor 6 for movement radially of the workpiece. The spindle 9 of the grinding wheel is rotated by a high frequency motor 14 supplied by a power unit 13. The load on the motor is sensed by a detector 15 which transmits a signal proportional to the load current to a comparator 16 for comparing the signal with a predetermined value set by a setting means 17 to adjust the frequency supplied by the power unit 13 to the motor 14. In operation, the grinding wheel motor 14 is driven so that the grinding wheel rotates at a speed N1 which is preferably lower than the speed corresponding to the resonance frequency of the spindle 9 with the grinding wheel out of contact with the workpiece. Table 8 is traversed so that the grinding wheel enters the bore of the workpiece and is reciprocated therein, and the infeed table 3 causes a rapid feed of the workpiece, a microswitch then being actuated to reduce the rate of feed for the grinding operation. As grinding starts, the load on the motor is sensed by the detector to increase the grinding wheel speed to N2 which is preferably lower than the resonance speed of the grinding wheel during grind. When the feed grinding is stopped and spark-out commences, the reduction in load on the motor 14 is sensed and the speed of rotation of the grinding wheel is reduced to N1, a second comparison circuit also reducing the speed of rotation of the workpiece, the length of time of spark-out being determined by a timer. During driving by a tool 12, the grinding wheel is rotated at its lower speed N1. In a second embodiment, the speed of the grinding spindle is controlled by the position of the infeed table 3 actuating microswitches. Alternatively, the changes in speed may be actuated by a sensor, such as an eddy current sensor, for detecting bonding of the grinding wheel spindle, a differential transformer responsive to the position of the infeed table, or a strain gauge for detecting deflection of the grinding wheel head 7.

Plastic compositions containing leather, indiarubber, &c.-In a leather-rubber composition, the following proportions may be used : 16 lb. rubber, 20 lb. leather flour, 5 lb. calcined magnesia, 3 lb. sulphur, 3 lb. brown factis; or, for a hard vulcanite material, 32 lb. rubber, 60 lb. leather flour, 16 lb. sulphur, and ¢ lb. magnesia. The composition is for making boot soles &c. and for coating canvas for printers' blankets, upholstery, &c., and the invention consists in the particular process employed. Crude, waste, or reclaimed rubber is masticated between rolls, and, while the rubber is un the rolls, an intimate mixture of leather flour, filling-material, and sulphur is added thereto, a small amount of factis or like fatty material being added to the rubber while being masticated, or to the flour mixture before it is combined with the rubber, and the mastication being continued to give an intimate mixture. The temperature of the rolls is then raised to effect partial vulcanization, the material is finally passed to calender rolls prior to complete vulcanization in a platen press or an open live-steam press. The final temperature of the rolls is about 240‹ F. The material may be passed through a refining-mil] prior to calendering. Tht sheets as delivered from the calender rolls, says 3/16 or 3/20 in. thick, may be superposed alternately in directions at right-angles to one another in order to give strength.
