Abstract: 232,639. Gomez, G. P. April 20, 1925. Machinery, utilizing inertia to obtain movements in.-The energy of positively driven rotating discs &c., 6, 7, Fig. 2, is transmitted to an axle 5 by means of the free oscillations of eccentrically loaded pivoted discs &c. 8, 9, 8<1>, 9<1>, Figs. 1 and 2, the shaft 5 being movable laterally so that teeth 24 thereon mesh with teeth on the oscillating discs only during half the period of oscillation so that the drive on the shaft is unidirectional. From the shaft 5 the energy is transmitted to whatever apparatus it is desired to drive, e.g. it may be used to relieve in part the drive of the discs. The oscillatory bodies may also transmit unidirectional movement by means of pawls. In the form shown in Figs. 6 and 6a the energy is transmitted by belts to pulleys 22<1> upon which are mounted as freewheels spurwheels 23<1> which mesh with a spurwheel 24<1> on the shaft 5. In Fig. 7 the belts in Fig. 6 are omitted: in Fig. 11 energy is transmitted from the oscillating bodies by a toothed rim 15 on the main rotating body which is belt-connected to a drum 20 so as to relieve the driving motor 17. In Fig. 12 spurwheels 23 mounted behind discs 7 are driven in one direction by the oscillating bodies and are geared to a wheel 24 on shaft 5. The oscillating bodies may be used in the production of electric current and may constitute in example the relatively moving parts such as armatures, field magnets, coils &c. of electric or electromagnetic operating devices.

Filed: 1972-03-07
Abstract: 1385935 Automatic control of textile machines TEXTILKOMBINAT COTTBUS VEB 7 March 1972 10540/72 Heading G3N A pattern forming textile machine is directly controlled from a multi-coloured grid type pattern master 4 whose colours are detected by photoelectric components 1 as different voltage levels are processed in the logic circuit shown to energize the appropriate operating segment 16 of the machine. The signals from components 1 are amplified in amplifiers 7 and are fed to discriminators 8. A comparison signal is provided on the second input to the amplifier from a scanning arrangement comprising a multi-coloured strip 9 and photo-cells 10 which provide in a sequence determined by switch 11 different voltages (corresponding to colour). When both voltages at the input to an amplifier are equal a standard level output signal, representing the colour on the pattern master, passes to discriminator 8 which has its other input connected to a similar constant voltage on line 15. The output signal passes through switches 14, which are closed in synchronism with switch 11, to the respective operating segment 16. Preferably all the photo-electric components along a line of a pattern are illuminated by the same source, for example, a fluorescent tube. The light may pass through or be reflected from the pattern and the colours used should provide distinct levels of output voltage from the components.

Title: A method and a device for crimping thermoplastic threads in a stuffer box
IPC: D02G1/12
Filed: 1957-04-02
Abstract: 821,179. Crimping yarn. ONDERZOEKINGSINSTITUUT RESEARCH N.V. April 2, 1957 [May 24, 1956], No. 10791/57. Class 120(3) In a method of crimping thermoplastic threads in which the threads are fed by clamping rollers into a heated portion of a stuffer box against the action of a mechanicalpressure, cooled in another portion of the box and finally released therefrom, a thread is led upwardly into a box containing balls the diameter of which are such that, above the nip of the rollers, two or more balls may simultaneously find a berth on both rollers and the number of balls is such that they fill the box to above the rollers when piled thereon and entirely cover the compressed thread during the crimping operation. At the commencement of crimping, the halls prevent the thread from fouling the junction between the ends of the rollers and the box; as crimping proceeds; the balls are propelled upwardly and form, on top of the compressed thread, one or more layers which promote uniform release of the thread and provide or contribute (together with a conventional piston) to the mechanical pressure. In the apparatus shown in Figs. 2 and 3, representing the static and crimping conditions, a tubular stuffer box 3 having a polytetrafluorethene lining 13 cooling ribs 4 and an apertured closure lid 14 carries a chamber 10, connected to a discharge (or delivery) pipe 11 and communicating with the box interior by radial channels 12, and is formed to accommodate and is urged by a spring 8 to engage spring-loaded driven clamping rollers 1, and contains balls 16. The thread may be preheated by passage through a capillary tube 18 of a tube system 17 which receives air from a pipe 21 heats it e.g. to 160‹C, by means of an electric element 22 and ejects it in the nip of the rollers 1 through the apertures formed at each side of the flattened end of a tube 19; this hot air and also the downwardly moving cool air passing through the compressed thread in the lower and upper part of the box are withdrawn through channels 12 and chamber 10. The lower end of the box 3 may be surrounded by a supplementary heating device and preheated air supplied to the box, above the rollers, e.g. from the chamber 10, may be further heated thereby e.g. to 190‹C. In the latter case, all hot air and the countercurrent of cooling air entering through the aperture 15 are withdrawn from the box at a point intermediate the supplementary heating device and the top of the compressed thread; the tube system 17 may be omitted.

IPC: H01H61/06
Filed: 1965-03-15
Abstract: 1,045,008. Thermal switches. LEHIGH VALLEY INDUSTRIES Inc. March 15, 1965, No. 10795/65. Heading H2B. [Also in Division G4] . A turn indicating system on a road vehicle is provided with means whereby the signal lamps are dimmed at night and the load on the flasher is maintained substantially constant so that the flash rate does not vary. The flasher comprises a rectangular snap vane 10 diagonally stressed by a thermally expansible pull ribbon 20 electrically connected at both ends to vane 10 and carrying a movable contact 21 at its centre. In parallel with the flasher is a similar thermal switch comprising a vane 40 carrying a movable contact 51 and stressed by a pull ribbon 50 surrounded by a heating winding 45. By day the switch 58 is closed and part of the lamp load passes through bleeder resistance 35. When the side- or headlights are switched on switch 58 is opened and the signal lamps are dimmed by resistance 55. At the same time winding 45 is energized causing contacts 51 and 52 to open so that the full lamp load passes through the flasher. The thermal switches and the resistance 35 may be arranged in a common casing and provided with three external terminals 16-18, Figs. 1-6 (not shown). Variations in flash rate due to changes in the voltage of the battery 43 may be reduced by the provision of a bimetallic element 60 surrounded by a heating winding 63 and co-operating with a contact 62 and bleeder resistor 61. If the battery voltage exceeds a predetermined level, e.g. 13 volts, the element 60 engages contact 62, the contact pressure increasing with increasing voltage, and part of the load passes through bleeder resistor 61. The bimetallic element 60 may be replaced by a snap vane 65, Fig. 8 (not shown).

Title: Method of extracting zinc from ores
IPC: C01G9/06
Filed: 1957-04-02
Abstract: Zinc is extracted from zinc ores comprising or consisting of silicates soluble under the reaction conditions, by leaching the ore with aqueous sulphuric acid in the presence of aluminium ions, digesting the reaction mixture to coagulate the silica and separating the resultant zinc sulphate solution.  According to the first aspect of the invention, 1-50% by weight of aluminium ions based on the soluble silica present is employed, preferably at or above 70 DEG C., said ions being supplied in the form of an aluminium salt or generated in situ by the addition of an ore containing alumina to the reaction mixture.  Coagulation takes place at a pH of 3.5-4: this is reached by neutralization of the acid with the ore or if desired by neutralizing with limestone.  The sulphuric acid employed may be a spent electrolyte which should not contain more than 50 g/l. H2SO4. According to the second and preferred aspect of the invention, said zinc ores and the aqueous sulphuric acid are alternately charged to the reactor, each addition of ore and of acid being followed by digestion at above 70 DEG  C.: in this modification of the invention the aluminium ions may be supplied from the zinc ore without further addition, if the aluminium content is sufficient.  Part of the digested suspension may be removed from the reactor as further charges are added and allowed to settle or thickened; part of the separated mud (preferably that part which has not become granular, and which takes longer to settle) may be returned to the leaching tank.  The sulphuric acid used may be a spent electrolyte and contain 10-30% H2SO4, and within this range it is preferred to commence operations with lower concentrations.  For either embodiment of the invention, a suitable aluminium salt solution may be obtained by reacting bauxite with a spent electrolyte at 70 DEG  C.  If it is desired to remove any silica remaining in the final solution, this may be done by adding ferric and/or aluminium ions and digesting the mixture.

Abstract: 215,741. Velut, R. May 12, 1923, [Convention date]. Dust-collectors. - A dust collector comprises stationary surfaces to which viscous material is supplied and from which it is removed by the application of heat. Fig. 2 shows apparatus comprising a series of superposed plates B supported on pipes A. Viscous material is contained in a reservoir D above the plates and is distributed to the plates by rods C disposed between them. The plates may be plane, corrugated or serrated in section, and the rods may be replaced by horizontal metal screens or perforated sheets. Steam is passed through a coil in the reservoir D to cause a flow of viscous material to the plates, which are heated to distribute the material by passing steam through the pipes A. Cold water may be passed through the pipes to cause the material to set. By heating the plates alone, the material is caused to drip into a receptacle E, from which it may be transferred to the supply tank after filtering. Fig. 3 shows plates formed with radial arms F which support the rods C. Successive plates of a column mav be in different vertical planes. Heating may be effected electrically, or by hot water, or the heat of the viscous material may be employed.
