Patent GB-545785-A (GB)
Abstract: 545,785. Cash registers. KOOPERATIVA FORBUNDET FORENING, U. P. A, and VIGBORG, K. M. Dec. 11, 1940, No. 17532. [Class 106 (i)] In machines having a start key for releasing the drive and an error-correcting key for releasing depressed keys, a member or members actuated by the start key are arranged to lock the error-correcting key at depression of a start key and vice versa. The depression of the start key 1 turns the lever 4 about the pivot 3 against the influence of a spring 5 causing a spring pulled angle lever 6 pivoted to the lever 4 to engage by its hook 7 a projection on a lever 9 pivoted at 8. This causes a projection 24 to move below a surface 25 and lock the error correcting key 2. When the lever 9 turns, the lever 10 falls to engage with its end a notch 23, under the influence of a spring 22 attached to a plate 17 on the shaft 15. The projection 18 is thus moved clear of a projection 19 on a cam 21 on the main drive shaft 20. When the key 1 is sufficiently depressed the arm 26 engages a fixed stop 27. The shaft 15 is connected to lever 10 by a linkage 14, 16. The shaft 20 makes a complete revolution in the direction of the arrow and the plate 17 is restored by a projection 28 on the cam 21 engaging the projection 29. If the error key is depressed the surface 31 takes under the flange 24 and prevents depression of the start key. In a modification a pin on the lever 4 is adapted to engage the notched end of the lever 9 to which is pivoted a spring lever with shoulders for engagement by arm 10 and angle lever 6. In a further modification, the lever 9 is dispensed with and a lever on a fixed pivot has shoulders to cooperate with arm 10 and lever 6 while a link pivoted to key 2 is guided on a fixed roller and provided with a shoulder to cooperate with a pin on lever 10. A final form shown in Fig. 4 is applied to a machine as in Specification 518,617. The angle lever 6 is pivoted to the start key 1 the knob 7 co-operating with the rod 14. The plate 17 is locked in one of two positions by a nose or a spring lever 43 engaging notches in the plate. One end of a lever 45 pivoted at 44 is pivotally connected to the rod 14 while the other end carries a pin 46 engaging a notch 47 in a member 49 pivoting on shaft 48. A displaceable rod 50 with a guide slot 52 is pivoted to the error correcting key 2 so that when the key is depressed a flange 53 takes below a shoulder 54 on the rod 14 preventing depression of the start key. A second similar guided rod 51 is connected at 56 to a member 57 fixed to the shaft 48. The member 57 is connected through a pin 59 and lug 58 with the detent 60 for the assistants and/or transaction key bank, the pin 59 entering a recess 61 in the detent. With the parts as shown, flange 55 prevents depression of the start key. The amount keys also cannot be depressed since they are locked by a bail 64 engaging recesses 65 in the detent. If an assistant or transaction key 66 is depressed, the member 57 is rocked and the bail drops allowing the amount keys to be depressed.

Iron oxide containing as impurities elements which form volatile halides is purified by contacting it with at least one gaseous hydrohalic acid at a temperature sufficiently high for said elements to be converted into halides and volatilized whilst the iron oxide remains substantially unconverted, and in the presence of water vapour, the amount of gaseous hydrohalic acid used being at least stoichiometric with respect to said elements, removing said halides by entraining them in a carrier gas, and recovering the concentrated iron oxide. The acid is preferably HCl, the reaction temperature 500-800‹ C., and the iron oxide may be preheated before being contacted with the acid gas in a fluidized bed. The HCl gas may be provided as such or introduced in a carrier gas, which may be water vapour, in which case this is achieved by volatilizing azeotropic (20% by weight) HCl solution, or may be produced in situ by dissociation of a suitable compound such as NH 4 Cl, with is supplied as an atomized solution, a sublimed vapour, or mixed with the iron oxide. In Fig. 2, pyrites ashes containing as impurities Zn, Pb, Cu and As, are fed via hopper 1 into bed 2, fluidized by the passage of smoke gases from combustion chamber 3 wherein natural gas from 4 is burned in air from 5, and 20% (azeotropic) HCl solution is injected in at 6, heated in exchanger 7, and reacts with the impurities in the bed 2. Dust is removed from the exhaust gas in cyclones 9 and 10, and the vapours of the chlorides of the metallic impurities pass into tower 12 where they are scrubbed with water, and tapped off as an aqueous solution at 15. Iron oxide containing substantially none of the above-mentioned impurities is drawn off at 8. Other apparatuses for performing embodiments of the invention are described.

Abstract: 1378768 Stuffer-box crimping NEUMUNSTERSCHE MASCHINEN-UND APPARATEBAU GmbH 10 Dec 1971 [16 Dec 1970 9 March 1971 6 Sept 1971] 57597/71 Heading D1F A method of crimping textile filaments e.g. monofilaments, multifilaments or fibre yarns, by introducing the filaments into a stuffer-box 5 by means of a stream of hot gas, is characterised in that a stream of cold gas is blown -into the stuffer-box in a direction counter to the direction in which the crimped filaments leave the stuffer box, the hot gas and cold gas discharging from the stuffer-box through lateral openings therein. The filaments 20 to be crimped are fed through an inlet nozzle 11 to a delivery pipe 9, hot gas being introduced into the inlet end of the pipe 9 via a pipe 3 and openings 10. The stream of hot gas conveys the filaments to the stuffer-box 5 where the reduction in pressure due to discharge of the hot gas causes the filaments to accumulate. The accumulation is also aided by the pressure of the cold gas flowing in counter-current to the filaments. The cold gas is introduced via pipe 4 to a take-off pipe 14 through which the crimped filaments leave. The delivery pipe 9, stuffer-box 5 and take-off pipe 14 are surrounded by a pipe 1 which is provided with openings, e.g. slots, in the region of the stufferbox. A housing 12 surrounds the pipe 1 and delivery pipe 9 and the annular space is filled with insulating material 13. A housing 17, 18 is provided surrounding the stuffer-box 5 and take-off'pipe 14; the housing 17, 18 being in communication with an extraction fan 23. The stuffer-box 5 is preferably formed from longitudinally extending spaced apart radial strips 6. - The hot and cold gases are preferably air, and the temperature, pressure and quantity of each is preferably. controlled. The cold gas stream may also incorporate a liquid e.g. water, in the form of a mist or evaporated therein. A dye may be dissolved in the water to colour the crimped filaments. The rate of extraction of the hot and cold gases via the fan 23 is preferably controlled; also, the rate of take-off of the crimped filaments via the pipe 14 is preferably controlled to ensure a constant quantity of filaments within the stuffer-box. The filaments may be heated prior to entering the stuffer-box.
