Abstract: 987,114. Mixing appliances. FRENKEL C-D A.G. May 15, 1962 [May 15, 1961], No. 17535/61. Heading B1C. A mixing appliance has relatively rotatable male and female members having facing helical threads of opposite hands, at least one of the threads having lands at least as wide as the grooves, and the cross-sectional area of one of the threads varying from a minimum to a maximum and of the other from a maximum to a minimum in complementary fashion. In Fig. 1 both members have lands 10, 13 wider than their grooves 11, 14 and the clearance 16 between the members is variable by axial adjustment of the male member by means of the handwheel 20. As shown, the mixing section 4 of the apparatus is preceded by a conveying section 3 and may deliver to an extrusion head 5. Fig. 8 shows an apparatus in which the male member 49 has lands 50 narrower than the grooves 51 while the female member has lands 53 wider than the grooves 54. The apparatus has a heating or cooling means 58. Male members having single and double start threads are depicted in Figs. 2 and 3 (not shown) and corresponding female members, formed in two longitudinal halves for ease of dismantling, in Figs. 4 and 5 (not shown). In operation material conveyed by the member having the diminishing groove (as shown, the male member) is exuded from the groove across the broad lands into the thread on the other member (see Fig. 7, not shown), being subjected to an intensive shaving action which can be varied by adjustment of the clearanec between the members. By suitable selection of thread combinations, the material may at the same time be compressed or attenuated in its passage through the mixer. The apparatus may be provided with suitable entry and exit means (not described) to adapt it for batch operation. Specification 842,692 is referred to.

Filed: 1934-06-16
Abstract: 419,931. Sewing-machines. FLOTTES, P., 4, Rue Guynemer, Montgerm, Seine-et- Oise, France. June 16, 1934, No. 17874. Convention date, June 26, 1933. [Class 112.] Chain-stitching by barbed needles.-In a chainstitch boot-sole sewing-machine, the needle is given a twist in its down position to wind the loop round the needle part to ensure its being lifted through the work. The thread f passes through the work supporting bracket 33 from the supply. The main shaft on being driven commences the rotation of the eccentric roller 11 and the slide block 9, whereby the bar 4 carrying the needle is given a downward displacement, rotation of the bar 4 being prevented by the wedge 8 engaging a projection on the cover. This downward displacement causes the needle 5 to penetrate the work c. At the lowermost point of the down position of the needle bar 4, the wedge 8 has passed the rotation-restraining projection and the teeth 13 mesh with the teeth 3<a> so that continued rotation of the shaft and bevel gear 3 imparts a complete turn to the needle. This twists the thread f into the barb. The teeth 3<a> clear the pinion 13 and the continued rotation of the shaft lifts the needle from the work bringing the thread f therethrough. A retaining finger 18 holds the previous loop open so as to ensure that the next loop is pulled through it. The bush 7 carrying the loop retaining finger 18 is moved up and down by the cam 15 and roller 16. Feed by awls.-The work is fed by a double finger member 26 carried by the limb 24 of a stirrup 23. Movement is imparted to the stirrup 23 by the projection 19 on the bracket 7. As the bracket rises, it imparts a displacement towards the left of the feeder 26. The finger 26b of this is pressed by a spring 25 into the work and impels it towards the left. The finger 26<a> engages a groove and guides the work.

[Class 40 (iv).] Relates to a permanent magnet for an electrodynamic loud-speaker, the walls of which are formed with two coaxially arranged apertures adapted to be engaged by a soft iron mandrel supported by the wall of the one aperture and forming with the other an annular gap, and consists in forming the magnet as a box-shaped body, cast in one piece, which, apart from the above-mentioned apertures, is entirely closed. The body may be cylindrical or have the shape of a polyhedron and is preferably of cobalt steel containing 9 to 15 per cent of cobalt. As shown in Fig. 1, the magnet comprises a box-shaped body 10, the walls of which are formed with axial apertures 11, 12. A core 13 is secured by a conical bolt 17 in the aperture 12, the upper end of the core forming with the wall of the aperture 11 an annular gap 14 in which is located a coil 15 attached to the diaphragm 16. The body 10 is formed so that for the permanent flux the section is substantially constant at any point except in the neighbourhood of the air gap, where the section attains a minimum. For this purpose, the thickness of the wall 30 containing the aperture 12 is shaped so that its thickness increases towards the aperture. Fig. 3 shows a device for magnetizing the body 10 comprising a heavy U-shaped magnet 20 provided with apertures 21, 22 through which are slid pins 23, 24 that engage in the apertures 11, 12 of the body. When the coil 25 is energized by a direct current, the magnetic flux traverses the upright walls 26 of the body in the same direction so that the latter is magnetized, whereupon the pin 24 is pushed through the apertures 11, 12 and the body removed from the device. The pin 24 is then removed by sliding the core 13 into the aperture 12 and the bolt 17 is tightened to secure the core in position.
