Title: Improvements in apparatus for the manufacture of superphosphate and the like
IPC: C05B1/10
Filed: 1951-08-09
Abstract: In apparatus for the continuous manufacture of superphosphate (Fig. 1), of the kind in which the fluid starting materials are fed into an annular channel defined by an outer wall 1 and a central mandrel 2, and wherein the mass carried round by the apparatus solidifies during the time it takes to reach a detaching member, as shown, a rotary blade-carrying member 9, attached to the upper platform 8, the outer wall 1 is stationary and integral with the platform 8, and the bottom wall 3 is rotatable and integral with the central mandrel 2.  A vertical <PICT:0714853/III/1> <PICT:0714853/III/2> wall disposed in the annulus between the feed point and the detaching member prevents the fluid mass spreading on to the latter.  The inner part revolves on bearing 4 and rests on rollers 5, 6; it is driven by gearing 11. Fluid tightness at the joints is effected by the use of a number of flexible. partially-overlapping metal plates 7, these extending along the base and vertical edge of the stationary partition and around the circumference of the outer wall to the point at which solidification occurs.  Inspection doors 12 are provided adjacent the detaching member.  The detached superphosphate falls on to conveyer 21.  In another construction, the annular chamber is of trapezoidal cross section, so that the mass tends to separate by its weight from the walls.  In a further construction, the mandrel is cylindrical, the diameter of the outer wall increases towards the bottom and the floor slopes downwardly to the outside.  Fig. 5 shows a construction wherein the axis of the detaching member 9 is external to the greater diameter of the bottom.  In all constructions, the radius of the stationary wall may increase slightly at the point where solidification occurs, either abruptly or gradually, again to promote separation of the solidified product from the wall.

Abstract: 237,906. Hahnemann, W. Aug. 4, 1924, [Convention date]. Void [Published under Sect. 91 of the Act]. Directive signalling.- Several aerials, preferably arranged in a straight line, are separated from each other by a distance approximately n-1 equal to - # where n is the number of aerials n used, and # is the signal wavelength. The currents fed to individual aerials may be dephased so as to obtain a rotatable maximum radiation vector. Fig. 5 represents the directional vector for five aerials spaced in this way. The exciting currents may be fed to the aerial system in phase, in which case the maximum directional effect is at right angles to the line of aerials. The feed currents may be dephased by a relative shifting of the stator of a high-frequency alternator, or by the use of rotating fields with stationary windings, or by means of graded and adjustable timelag circuits inserted in the leads l<1> - - l<4>, Fig. 7, between each aerial and the receiving or transmitting station i. Screening means of known type may be added to secure a one-sided directional vector. Specification 207,536 is referred to.

Class 146(2) A triple use envelope has a front panel 15 with a window 16, a rear panel 17, two integral or attached obscuring flaps, and retaining means separate from or forming part of one of the obscuring flaps each. obscuring flap may be folded within the envelope, or sealed to the upper portion of the front face where it will obscure the previous stamp and postmark but no part of the window. For the first transmission the obscuring flaps 19 and 20 are tucked in the envelope, and for the second transmission, with flap 20 in the envelope, flap 19 is secured to the front panel, obscuring the stamp &c., as in Fig. 3. The envelope is then opened by tearing flap 19 along one or more lines 21 of perforations, or by means of a tearing thread, the remaining portion 22 of the flap serving to retain the enclosure during the third transmission when the envelope is sealed by flap 20 which obscures stamp &c. 24, as in Fig. 5. A retaining flap may be formed by folding, as at 28, one of the obscuring flaps 25, 26, by securing a separate strip to the inside of panel 15 or 17, or by cutting an obscuring flap and folding over the separated portion 29, as in Fig. 9. To facilitate the opening of the envelope, sealed as in Fig. 3, a lip for gripping may be formed on flap 19.

Abstract: 501,113. Mechanical presses. PARFITT, A. W. (Majik-Ironers, Inc.) June 29, 1938, No. 19265. [Class 87 (ii)] [Also in Group VIII] A press is provided with a prestressed pressure spring or equivalent unit which is pivoted between the press frame and one of the press members so that the press may be freely opened or closed without having to overcome the force of the pressure unit which may be swung, after closing or before opening, to various positions-to vary the magnitude of its effect on the press members. In the simple form shown, wherein the head lever 4 is pivoted at 5, the unit comprises a prestressed spring 12 pivoted at one end 13 to a stationary post 14 and at its other end to a link 9 which is pivoted to the head lever at 10. A stop 16 on the link coacts with the head lever. The link and spring are substantially of the same length and when the press is open the pivot 5 and the pivot of the spring with the link are substantially in alignment so that the spring offers no resistance to the swinging movement of the head. After the press has been closed, the pivots 10, 13 substantially coincide and the spring unit may be rotated by a handle 15 into a pressureapplying position. Several more elaborate embodiments are described including one wherein the pressure unit comprises a Sylphon bellows arrangement. The pressure exerted may vary, according to the form of the apparatus, from a few hundred pounds to several thousand pounds. The effects of arranging that the various centres of rotation do not coincide are discussed in the Specification.

A traveller for a conical ring, that is one having a triangular cross-section, is of partially triangular form and comprises at least a base portion and a perpendicular portion, the latter being thickened both in a radial and in a circumferential direction with reference to the ring, and is composed of a non-metallic material such as a synthetic resin. As shown the traveller is of triangular form having the base 1 of substantially uniform thickness but with a width expanding from the top and a perpendicular which increases downwards both in width and thickness to the line A-B. The hypotenuse is represented by the short hooked extensions 3,4 and the inner faces of both the perpendicular and the base are made smooth and of similar form to the inner surfaces of the ring 5. The traveller may be made of a synthetic resin such, for example, as nylon. Instead of the increase in width being arranged symmetrically as shown it may be arranged asymmetrically to avoid or reduce tilting of the traveller during use. In a further embodiment the lower end of the traveller is formed with a flat surface which engages a step formed on the inside surface of the ring. Reference has been directed by the Comptroller to Specifications 627,157 627,370, 627,371, 627,372, 627,373, 627,374 and 627,375.

Abstract: 460,419. Automatic control systems. FABRIK ELEKTR. APPARATE F. SAUTER AKT.-GES. July 13, 1936, No. 19409. Convention date, July 13, 1935. [Class 38 (iv)] Temperature, fluid pressure, humidity, &c. are maintained constant by a regulating member such as a valve actuated by a reversible electric motor subject to periodic impulses, the sense and duration of which are determined by a control member responsive to the characteristic controlled. According to the invention, the impulse transmitter comprises a rocking mechanism which under normal conditions is displaced equally from a central position and is connected through a sun-and-planet mechanism to the control member so as to rock in one or other direction beyond its normal amplitude to a greater or less extent according to the displacement of the control member. A constantly running cam 4 rocks a planet-wheel 12 and sun-wheel 13 coupled to a cam 15 so that the projections thereon do not normally cause the tilting of either of the mercury switches 1611, 161, which lie in circuit with the opposed fields of the valve motor 22. A control member 25 is adapted to turn a second sun-wheel 31 in accordance with changes, for example, in the pressure on a diaphragm 24, so that the cam will periodically tilt one or other switch for periods depending on the degree of displacement of the diaphragm. Sufficient displacement may produce continuing closure of a switch.
