Filed: 1929-09-16
Abstract: 328,531. Singer Manufacturing Co., (Assignees of Barron, W. L.). Oct. 26, 1928, [Convention date]. Lock-stitching by hooks. - A rotary-hook machine of the general type described in Specification 5667/15 is provided with means associated with the bobbin-case restraining mechanism, for assisting the needle to throw out its loop for engagement by the hook to facilitate embroidering operations where the work is shifted by hand to place the stitches in accordance with the desired pattern. The bobbin-case restraining means comprises a bar with a notch for the needle and a supplementary notch for the needle-thread loop. As illustrated, the machine has a bed 1, a needle-bar 3, a needle 4, a throat-plate 5, a four-motion feed dog 7 and a feed-cover plate 8 upon which the fabric 9 is placed for embroidering, the plate 8 rendering the feed-dogs ineffective. The underthread mechanism includes a cup-shaped rotary-hook body 16 carried by the shaft 17 and provided with a loop-seizing hook 18 and a bearing rib 19 for the flange 20 of the case 21 of the bobbin 22. The bobbin-case restraining bar 26 is screwed to lugs 25 and has a notch 27 entered by the curved end 28 of a finger pivoted at 29 on a lug 30 of the bobbin-case 21. The finger has a tail 31 entering a large hole 32 in the bobbin-case and is pressed outwardly therein by a spring 33. In operation, the frictional drag of the hook body on the bobbin-case keeps the finger 28 in engagement with the, side 35 of the mouth of the notch 27 in the bar 26, leaving a narrow curved gap 36, Fig. 2, between the curved finger 28 and the side 35<1>. The side 35 is closed and is engaged by the limb 37 of the needle loop 38, Fig. 1, forcing the loop to expand into the notch 27 for seizure by the hook 18. When the hook reaches its cast-off position, the expanded needle-loop 38' is free to be contracted, as by manual shift of the work, to the dotted line position 38<11>, Fig. 2; the end of the bearing 19 then opens the gap 23 in the flange 20 to allow the needle loop to escape between the finger 28 and bar 26, the finger yielding about its pivot 29 to open a gap without necessitating a shift of the entire bobbincase.

Title: Improvements in and relating to oscillatory acoustic devices
IPC: H04R1/28
Filed: 1932-10-10
Abstract: 412,194. Gramophones &c. GOLDSCHMIDT, R., 7, Bundesallee, Charlottenburg, Berlin. Oct. 10, 1932, No. 28234. Convention date, Oct. 10, 1931. [Class 40 (ii).] Relates to oscillatory acoustic devices, such as gramophone soundboxes, loudspeakers, and the like. According to the invention, the frequency range of such apparatus is improved by the attachment, in a special manner, of an auxiliary mechanical system or element which is capable of vibrating in a number of different modes, according to the frequency of the actuating and reactive forces operating on the main system. The auxiliary vibratory system comprises a mass pivotally or yieldingly connected to a transmission member of the main system, and the arrangement in accordance with the invention is such that vibratory energy can be transmitted from the driving element to the main driven element even if the auxiliary mass is fixed, or from the driving element to the auxiliary mass even if the main driven element is fixed, and that, in actual operation, the mass can vibrate in a number of different modes. A gramophone sound-box to which the invention is applied is shown in Figs. 6 and 7. To the stylus-bar H, connected to the diaphragm K, is fixed a pin L which rests in a ball bearing F on the casing N. The stylus-bar carries a cross bar R upon which a mass P is pivoted at U, U. The centre of gravity of the mass is offset from the axis U-U, as well as from the centre line of the stylus-bar, and the mass is thus capable of several different modes of vibration. The different natural frequencies at which the auxiliary vibratory system is adapted to resonate are preferably so chosen as to cover a frequency range in which the response tends to be too weak. Its effective working range may, advantageously, lie at very low frequencies. The principles of the invention are explained in the Specification with the aid of diagrams.

Title: Roasting of arsenopyrite gold-bearing ores
IPC: C22B1/10
Filed: 1950-11-23
Abstract: Arseno-pyrite gold-bearing ore solids are roasted by fluidized-solids technique firstly in a bed in which the amount of oxygen in the fluidizing gas is sufficient to oxidize the ore to yield volatile arsenic compounds (arsenious sulphide and oxide), but insufficient to yield non-volatile arsenic compounds (arsenic pentoxide), and then in a bed in which the oxygen-bearing fluidizing gas is sufficient for complete oxidation.  The solids are thus rendered particularly amenable to cyaniding.  As shown, finely divided ore is fed into a refractory-lined vessel to form a bed 17 and after the preliminary roasting therein, at a temperature above 450 DEG C, but below that causing fusion, passes through pipe 19 to the second bed 18 whence after being roasted, suitably at 625 DEG C, but below fusion, it is discharged through pipe 29.  In starting the process, air is supplied through conduit 40 together with natural gas, &c., or liquid fuel may <PICT:0677050/III/1> be supplied through pipe 70, and inert material is fed to the beds.  When a temperature of 800 DEG C is reached, the inert material is replaced by ore, and the auxiliary fuel is shut down.  The oxidizing gas passes from the lower to the upper bed via a cyclone 51, and from the upper bed to cyclone 36, whence dust is passed via pipe 57 to the lower bed.  The temperature may be controlled by water sprays 72.

Abstract: 464,434. Thermal switches. BRITISH THOMSON-HOUSTON CO., Ltd., and RULE, W. Oct. 18, 1935, No. 28847. [Class 38 (v)] [Also in Group XIII] Circuits 13, 14 containing lamp filaments or other consuming devices (not shown) are alternately closed by successive actuations of a switch 2 through the medium of a device comprising two bimetallic strips 6, 7 which are heated by conductors 3, 4 and are adapted tc make contact alternately with a strip 10 arranged between them. The strips 6, 7 are each made of two portions oppositely directed so that variations of ambieni temperature are compensated for and the portion 9 of each strip opposite the heater 3 or 4 is dulled while the remaining portion 8 is brightened. When the switch 2 is closed a circuit is completed through both heaters 3 and 4 and the strips 6, 7 bend towards each other till one strip, the strip 6 in the figure, engages the strip 10. This closes the circuit 13 and short-circuits the heater 4 so that the strip 7 cools, but the heating of the strip 6 continues and this bends further to the left carrying the strip 10, which is non-resilient, with it. When the switch 2 is opened, the strip 10 is thus left nearer the strip 7 so that when the switch 2 is again closed, and the strips 6, 7 again bend towards each other, the strip 7 will now be the first to engage the strip 10, and short circuit the heater 3 through the lamp filament in the conductor 14.
