Title: Improvements in apparatus for making edgewound coils
IPC: B21C37/26
Filed: 1926-12-07
Abstract: 262,775. Whittingham, G. H. Dec. 11, 1925, [Convention date]. Coiling; dies.-Open-wound helical coils for electric resistances &c. are coiled in a succession of steps in a machine of lathe form, the length of helix produced being longer than that of the mandrel employed. The main part c, Fig. 3 of the two piece helical die employed is mounted in a counterbored recess of the holder 10 carried by the saddle and positioned axially by backing- up screws. Both die parts are hardened and cooperate with a hardened bar 13 which guides the strip into the die and is recessed both into the holder and into the cover 16 which carries the other die part e, and is secured by a row of bolts below the bar. The other holes in this holder receive bolts which pass through into tapped holes 19 in tha cover for adjusting the pressure of the die on the strip. Initially these bolts are slacked back clear of the slit in the die and the strip is introduced at s. The end is bent over and wedged at 20 into the faceplate of the machine. The spindle is rotated to form the first part turn and the cover bolts are then returned to place and adjusted. The mandrel 3 is secured in the spindle, passes through the die and is guided in the tailstock. The saddle is traversed by the leadscrew as coiling proceeds up to the full length permitted by the bed. The spindle is then reversed for one or two rotations to free the grip of the coil on the mandrel and the saddle is racked back compressing the coil into close formation f, a further length f<2> is then coiled as before and this is compressed and so on until the mandrel is almost completely filled. The strip is then severed close to the die the coiling is completed right up to the severed end and the tailstock and saddle are moved outwards along the bed clear of the mandrel to release the coil which discharges itself almost completely from the mandrel by virtue of the elastiticity of the strip.

Abstract: 1285872 Stretching; working at specified temperatures ELECTRICITY COUNCIL 21 Aug 1969 [28 June 1968] 31073/68 Headings B3E and B3V The cross-sectional area of a metal article 10 is reduced by drawing apart two clamps 11, 12 at a controlled rate and simultaneously traversing a heated zone along the article 10 so as to extend it at the controlled rate. In one embodiment, an induction coil 13 is moved along the workpiece 10. Alternatively the article 10 is traversed through the heater or the heater and article are both moved. The material is cooled by a liquid or gas as it leaves the heated zone. The article may be a wire, strip, rod, tube, threaded member, a T-section bar, a channel section or ribbed bar, which article is reduced uniformly or non-uniformly along its length to produce a 50% or more reduction of area in one pass. In examples described, a steel is worked at various temperatures ranging from 725-1060‹ C., a 6% Al-4% V titanium alloy from 908-980‹ C. and a zirconium alloy at 875‹ C. Steel may alternatively be worked at 500-900‹ C. In another embodiment, a steel is ausformed by austeritizing the steel, moving the heated zone along the article and applying tension to the part which is cooling after having been heated.

Title: Data handling systems

Abstract: 1515525 Data handling system UNITED KINGDOM ATOMIC ENERGY AUTHORITY 20 July 1976 [25 July 1975 7 May 1976] 31269/75 and 18705/76 Heading G3N [Also in Divisions H3-5] A data handling system is used, e.g., to control machinery and industrial processes and has duplicated facilities to reduce errors. The system monitors electric analog signals originating from each of six locations, there being four transducers A-D at each location sensing the same parameter. Four scanning multi-plexers 7-10 each receive a signal from each location, together with two interleaved test signals T, and the outputs pass via respective A/D converters 11-14 to respective digital computers 15-18. The computer output for plant control is chosen by a 3 out of 4 majority decision among the computer outputs. In a computer a primary shift register Fig. 2 (not shown), receives the digital signals from its A/D converter and recycles the signals after each complete scan of the analog signals. Signals from this register are compared with a stored threshold to yield a binary 0 or 1, and the resulting bits from a number of cycles are stored in primary status registers. A majority voting circuit responds to a majority of status bits from the primary status registers to indicate a fault. The ultimate plant control depends on the 3 out of 4 majority of the four computers.

Abstract: 867,373. Electrolytic testing apparatus. KLEES, P., and KLEES, K. F., [trading as KLEES GEB.]..Sept. 15, 1959 [Sept. 15, 1958], No. 31401/59. Class 37. A cell for the electrolytic generation of reagents, used, for example in continuous titration processes, comprises a casing 2 across which extends a mass of ion-exchange material 4 to divide the cell into two outer compartments, each compartment containing electrolyte and an electrode 3, the electrode in one of the compartments being surrounded by a tubular porous diaphragm 1 through which flows the electrolyte 6 in which the reagent is to be generated. By this means unwanted components generated are fixed by the ion-exchanger and consequent loss of reagent due to recombination after its production is prevented; the quantity of reagent produced is thus accurately proportional to the quantity of electricity fed to the cell. In the arrangement shown in Fig. 1, the electrode in the other compartment is surrounded by a tubular porous diaphragm similar to the diaphragm 1; in the modification of Fig. 2, however, a porous diaphragm 7 is arranged between this compartment and the ion-exchange material, electrolyte flowing continuously through the compartment from an inlet tube 8 to an outlet tube 10. The electrode 3 may be divided into two or more part electrodes each with its separate current supply, Fig. 3 (not shown; this simplifies the fine control of the current supply to this electrode. Fig. 4 shows the application of the cell of Fig. 1 to a continuous titration process. The solution to be titrated is fed through the tube 1 to a pH-measuring section 13 connected to measurement means 14 controlling a motor 16. The motor 16 positions the wiper arm of a potentiometer 17, so adjusting the current supplied to the cell as to maintain the pH measured in the section 13 at a desired value. The current flowing is indicated on a meter 18 and provides a measure of the cocentration of the ions being titrated in the solution flowing through the tube 1.

Filed: 1928-10-30
Abstract: 301,864. Kunstd³nger-Patent-Verwertungs Akt.-Ges., (Assignees of Liljenroth, F. G.) Dec. 7, 1927, [Convention date]. Grant of Patent opposed. Phosphoric acid; ammonium phosphates.- In the production of phosphoric acid or soluble phosphates by leaching raw phosphates and separating the calcium from the solution as calcium sulphate, a temperature of at least 80‹ C., say 95‹ C., is employed for the separation, whereby a crystalline form of the sulphate which settles rapidly is obtained. The process may therefore be carried out with concentrated solutions of the reagents. Alkali salts such as potassium or ammonium phosphates, sulphates, nitrates, or chlorides may be present during the separation. The leaching and separation may both be effected at the high temperature, or the calcium be first brought into solution. and be then precipitated at the high temperature, or the calcium sulphate be first precipitated at a lower temperature, and the temperature be then raised above 80‹ C. Sulphuric acid with or without an alkali sulphate, or nitric or hydrochloric acid with the necessary amount of an alkali sulphate may be used for the leaching. When ammonium sulphate is used as precipitant, the raw phosphate may be mixed with a solution thereof and then the acid be added; when potassium sulphate is used, it is dissolved in the leaching acid.
