Title: Improvements in automatic electric regulators
IPC: G05D23/30
Filed: 1939-12-18
Abstract: 538,118. Thermal switches. DAVIS, N. R., WETHERILT, J. N., and SUN-VIC CONTROLS, Ltd. Dec. 18, 1939, No. 32453. [Class 38 (v)] [Also in Groups XXXV and XIII] In the operation of a regulator which intermittently closes an electric circuit or changes the relation between condenser plates in the control circuit of a space discharge tube a change in relation between the mean position of an element 1 and an element 6 responsive to a regulated quantity occurs which causes a change in the said quantity. In order to prevent this the comparison contact 2 is caused to change its position in a direction in accordance with the average value of the interrupted current. As shown the element 6 is responsive to a temperature controlled by a heating element 14 supplied through the contact elements 1, 2 which are bimetallic and heated by windings 8, 9 in parallel with each other and with the element 14. The auxiliary contact element 2 is arranged to take a mean temperature varying with the average value 7 the current in the winding 9. The element 1 turns about the axis 4 with change in the controlled temperature. In modification, one of the companion contacts is carried by the temperature responsive element and the other by a bimetallic strip which turns about a fixed axis under the control of the auxiliary bimetallic element. In other modifications, the bimetallic element 1 is carried by an auxiliary bimetallic: element rigidly supported at one end and bending in the opposite direction to the element 1 on heating. The two elements may be heated by windings, e.g. in series with one another, but the auxiliary element may be heated conductively from the element 1 in order to attain the mean temperature required. The heat storage capacity of this auxiliary element may be variable for adjustment purposes. Fig. 6 shows the element 2 supported by a member 33 containing a quantity of mercury which may be removed from a plugged aperture to change the thermal capacity. Lagging 34 covers the auxiliary element 2 and the member 33. Since the elements 1, 2 move in opposite directions they may be arranged also to compensate changes in ambient temperature. The invention is not restricted to regulators in which the intermittent current is produced by thermal means.

In a method of constructing an underwater pipeline in which additional lengths of pipe 5 are joined at or near the water surface to the end of a pipe 1 already laid and extending from the water bed 3 upwards through the water, floats 7, 8 are attached to the length of pipe between the bed and the joint, the bouyancy and spacing, or both, of the floats along the pipe being arranged so that the lift per unit length on the portion of the pipe near the bed 3 is less than that on the portion nearer the joint and the longitudinal curvature of the pipe is limited so that it is not overstressed or buckled. As shown, the floats are so arranged that there is a point of contraflexure 10 in the longitudinal curvature of the pipe and the change in the bouyancy per unit length of the point occurs at substantially the point of contraflexure. The floats are attached to each new section 5 and may be equally spaced and alternately of larger and smaller size the latter being freed from the pipe, as the pipe-jointing, floating platform 9 moves to a new position, when they pass the point of contraflexure. The pipeline may first be laid on the bed and the end of each sunken pipe raised by the attachment thereto of water filled bouys which are subsequently pumped out by compressed air, the bouys being released from the pipe after jointing of the pipes.
Patent GB-775010-A (GB)
Title: Improvements in or relating to methods and apparatus for the manufacture of ammoniumsulfate
IPC: C10K1/10
Filed: 1953-11-26
Abstract: <PICT:0775010/III/1> In a cyclic process for recovering ammonia from ammonia-containing gas by circulating an aqueous sulphuric acid solution between ammonia absorption and ammonia sulphate crystallization stages, a portion of the mother liquor from the crystallization stage is subjected to vacuum evaporation and is then returned to the main circuit before the crystallization stage.  The size of the crystals obtained is determined by the humidity of the ingas and the degree of vacuum in the evaporator.  The humidity of the gas may be increased by the addition of ammonia still steam or steam from a non-condensing turbine circulating pump.  Coke-oven gas may be treated.  The system may be operated under hydrostatic or super-hydrostatic pressure.  The solution from the crystallization stage may be passed directly to the absorption stage or may be mixed first with make-up acid or water.  In the latter case the solution sprayed in the absorption zone may be unsaturated with respect to ammonium sulphate.  Pyridine may be recovered as described in Specification 653,325 or U.S.A. Specification 2,311,134.  As shown a second absorption zone 250 is employed, solution from both absorption zones being combined, a portion of the combined solution being passed via pipe 258 to the second absorption zone after the addition of make-up acid and sufficient make-up water to give an unsaturated solution, and the remainder being passed to the crystallization stage via pipe 18.  A pump 26 passes solution under pressure through a closed pressure-tight crystallization bowl 14.  Ammonia still steam may be used to expel pyridine from liquor withdrawn as a side stream from any part of the circuit in which case pump 26 may be a non-condensing turbine pump and steam therefrom may be added to the gas being treated.  The first scrubbing liquor may contain 1-12 per cent sulphuric acid and the second up to 40 per cent sulphuric acid, and the relative volumes may be such that at least 75 per cent of the ammonia in the gas being treated is absorbed in the first absorption zone.  The dew point of the out-gas is preferably equal to or less than the dew-point of the in-gas as described in Specification 773,147. Minor modifications are illustrated in Figs. 1 and 2 (not shown).

Filed: 1967-07-18
Abstract: 1,191,159. Electrostatic printing; stencils. RANK XEROX Ltd. 18 July, 1967 [20 July, 1966], No. 32866/67. Heading B6C. [Also in Division G2] A negative reproduction of a light pattern is formed by placing the surface of a donor sheet 3 in contact with the positive imaged and developed surface of plate 1 and applying a potential to one of layers of the so-formed sandwich of like polarity to particles or that one layer. The plate 1 may be of paper or polyethylene terephthalate carrying a xerographically formed positive image developed with a positively charged non-pigmented toner. The donor sheet 3 is coated with pigmented toner particles 4 negatively charged to a greater potential than the non-pigmented toner. When a negative charge is applied to the lower surface of sheet 3, the particles 4 are repelled towards the surface of plate 1 to produce a negative reproduction 15, Fig. 5. In one example, Example I, a sheet of zinc oxide paper is charged to - 400 volts and imagewise exposed to a positive image and developed by cascading with non-pigmented toner, e.g., polystyrene. A donor sheet of "Mylar" (Trade Mark) carrying pigmented negatively charged toner was placed in contact with the positive image and a negative charge of 600 volts was applied to the donor sheet to form a negative developed image on the zinc oxide paper which was then heat fixed. Instead of fixing, the negatively developed image was transferred to a transparent acetate sheet for use in a display device. Alternatively, the negative image was transferred to a silk screen and then heat fixed for use in printing.

Filed: 1921-12-08
Abstract: 173,494. Kohler, C. Dec. 24, 1920, [Convention date]. Void [Published under Sect. 91 of the Act]. Railway locomotives, turbine.-In turbinedriven locomotives running on given routes at a predetermined scheduled speed between stations, that is for the greater part of the journey, the gearing between the turbine and axles is of such ratio that the peak on the turbine efficiency curve is attained before the said scheduled speed is reached. Curves a and b represent the efficiency curves of the turbine for various locomotive speeds, the point of maximum efficiency of curve a corresponding to a speed of 65 kilometres per hour. According to the invention, if the scheduled speed attained between stations is, for instance, 65 kilometres per hour, the gearing between the turbines and axles is selected so that a curve such as curve b represents the efficiency of the turbine, maximum efficiency in this case being attained when the speed is only 55 kilometres per hour.

Title: Improvements in or relating to paddles for operating in the forehearths of glass furnaces
IPC: C03B5/187
Filed: 1936-12-02
Abstract: 482,615. Glass manufacture. ARMYTAGE, F. W. Dec. 2, 1936, No. 33018. [Class 56] Relates to a paddle for circulating molten glass in a forehearth used in conjunction with a forming-machine which gathers by suction. According to the invention, the paddle has a compound continuously-variable motion derived from two adjustable crank or eccentric mechanisms which control the length of stroke and the depth to which the paddle dips into the glass, the arrangement being such that the motion of the paddle tip can be varied from a circular to an elliptic movement with the major axis either horizontal or vertical. The paddle blade 1, Fig. 4, is attached to a shaft 4 which is secured to a link 2a, Fig. 1, that forms part of a link parallelogram 2, an opposite link 2b being secured to a crank arm 9. An adjustable rod 10 connects the crank 9 to a nut 11 which is threaded on a screw 12 pivoted to the frame of the machine. The free end of the screw 12 is rocked by a link 14 and a crank on a driving-shaft 15. Thus the rotation of the shaft 15 causes oscillation of the shaft 4 and a to-and-fro movement of the paddle 1, and the length of the stroke can be varied by turning the screw 12, by means of a hand wheel 12x, to alter the position of the nut 11. The links 2 are pivoted, by means of the shaft 4 and another shaft 5, to a beam 3 which is connected by a pivoted lever 19 to the frame of the machine. The centre point 20, of the beam is connected by a pivoted link 21 to a fixed bracket 22, and also by an adjustable rod 23 with a screw 25, similar to the screw 12, which is rocked by a crank 26. The movement of the beam 3 dips the paddle 1 into the glass, and the screw 25 enables the amplitude of the vertical movement to be adjusted. The use of the screws 12 and 25 enables the movement of the paddle to be varied from circular to elliptical. The weight of the beam 3 is counterbalanced by a weight 28.
