Abstract: 989, 777. Grading metal sheets. R. W. CRABTREE & SONS Ltd. Aug. 2, 1961 [May 2, 1960], No. 15456/60. Heading G1M. In a machine for stacking metal sheets standard sheets pass on a conveyer 5 to an acceptance station 8. A non-standard signal may operate a solenoid 11 to deflect downwards a plate 3 passing the faulty sheet to conveyers 7, 9, and thence to a reject station 10. The machine is characterized by the acceptance station having a sheet-stacking unit equipped with a sheet-receiving support and with means to lower the support as sheets are successively delivered to it. A framework 18, for supporting a pallet 17 on to which the sheets are fed by the conveyers, sinks as the stack builds up under the control of a photo-electric device. When a pallet is full it is carried off by rollers 19a and a further pallet supplied, the incoming sheets being in the meantime supported by rods 20 which are automatically retracted when a pallet is in the receiving position. The forward momentum of a sheet leaving a conveyer is partly absorbed by a rubber cushion 27 on a pivoted arm 24. A weight 26 returns the deflected arm to a vertical position thereby pushing the sheet into correct stacking alignment against plate 30. A manually-controlled deflecter 14 directs a sheet on to a support 16 for inspection if desired.

Title: Warp thread drawing-in machine
IPC: D03J1/14
Filed: 1931-05-30
Abstract: 379,703. Threading loom healds, reeds, &c. BISSIG, H., Uster, near Zurich, Switzerland.-(Assignee of Samitz, 0. ; Ebensee, Austria.) May 30, 1931, No. 15901. Convention date, May 31, 1930. [Class 142 (ii).] Relates to means for operating and guiding the long flexible needle 25, shown in plan view in Fig. 2, which is used for drawing warp threads through loom healds, reeds and warp stop-motion hooks. This needle is covered by an elastic steel band 48, which is wound up with it on a disc 45 and when the needle unwinds to make its forward movement is wound on a second disc 49. The needle lies in a groove 47, Fig. 3, in the disc 45, which is positively rotated by bevel and rack gearing described to wind up the drawing-in needle and the guiding band. The disc 49, which at this time can run idly, is turned by the pull of the band 48. Conversely the disc 49 is positively rotated in the direction of the arrow V to wind up the band 48, which rotates the disc 45, and moves the needle 25 forwards. Immediately after leaving the band, the needle is guided by an enclosed straight guide 51, and afterwards by a guide member 52 situated in front of the reed with a slot 521 open at the top and by guides 53 situated in front of each of the heald shafts, the heald eyes of which are to be threaded, and the warp stop motion hooks arranged in rows on one or more rails. Each guide 53 has a flared orifice and a lateral slot through which, on the return stroke of the drawing-in needle, the drawn-in warp thread can pass laterally. The guide member 52 is moved up and down by cam-controlled lever mechanism, its downward movement occurring on the return stroke of the drawing-in needle, springs 56 situated above the slot 52<1>, being displaced by the needle. When the forward member 52 is raised before the forward stroke of the needle 25, the obliquely disposed springs 56 engage the warp thread previously drawn in and displace it out of the path of the needle 25. A fixed slotted guide 54 is also used. In a modification, the funnel guides are substituted by fixed guiding-members having guiding- slots completely open at one side to facilitate the escape of the drawn-in warp threads. These slots are closed, however, during the forward movement of the drawing-in needle by slides movable thereon. Leaf springs on the slides glide in vertical grooves in the fixed members and lift and push aside warp threads remaining in the guide.

Title: Extrusion process for making propellent grains
IPC: B29C48/04
Filed: 1961-05-03
Abstract: <PICT:0964801/C1/1> <PICT:0964801/C1/2> Solid propellent grains are made in a continuous process by introducing into an elongated cylindrical barrel a fluid plastisol comprising organic polymer particles and inorganic oxidizer particles dispersed in an organic plasticizer, heating the plastisol to dissolve the polymer by producing shear stresses in the mass while moving it in a helical path, passing the soft gelled product through a shaping passage, and then cooling to form a rigid gel.  As shown in Fig. 1a, the plastisol is fed at 22 into barrel 2 containing rotating screw worm 4 which drives the plastisol along the barrel and produces the frictional heat; a jacket heated by hot oil or superheated steam may also be provided. Different back pressures in the barrel 2 are obtained by varying the size of passages 8 and axial plug 9.  The soft gel passes into heated die 11 from which it is extruded into tank 17 containing cooling water 19 (see also Fig. 1b).  A take-off unit 16 pulls the extrudate from the die at a rate determined according to the diameter of the extrudate as measured by non-contact photo-electric device 14. Propellent grains are formed by cutting the material automatically into predetermined lengths by saw unit 20 (see Division B5) controlled by microswitches 49, 51. Centrally perforated grains may be obtained by using an axial mandrel in the die 11, or grains of cruciform cross-section by shaping the walls of the die.  Metal wire conductors 31 may be embedded in the grains by continuous introduction through guide tubes 321 in the walls of die 11; these wires may be of silver, copper, aluminium, steel, or tungsten and may have a self-oxidizing or insulating coating in order to control the burning rate.  Compositions.-The organic polymer may be polyvinyl chloride, a copolymer of vinyl chloride and vinyl acetate, or cellulose esters or nitrocellulose as described in U.S.A. Specifications 2,809,191, 2,931,800, and 2,931,801.  Suitable plasticizers are esters of phthalic, adipic, and sebacic acids, high molecular weight fatty acid esters, and nitroglycerine.  Finely divided oxidizers referred to are ammonium, potassium, sodium, and lithium perchlorates and nitrates, and sodium, barium, and calcium peroxides. Other optional ingredients are powdered aluminium, magnesium, boron, titanium, and silicon, and the composition may also contain copper chromite and ammonium dichromate as burning rate catalysts, monobasic ammonium phosphate as a coolant, and carbon black as an opacifier.  In an example the composition contains ammonium perchlorate, polyvinyl chloride, dioctyl adipate, powdered aluminium, a stabilizer, and a wetting agent. At the start of the process, an inert composition, containing potassium chloride instead of ammonium perchlorate, may be used, so that adjustments may be made in safety.
