Title: Urea particulates and method of producing same
IPC: C05C9/00

The solid fatty acids and derivatives may be melted and applied to the urea, or contacted as a vapour, or as with the hydrocarbon may be dissolved in an inert solvent for contacting with the urea.  Alternatively the urea particles are agitated at for example between 60 DEG  and 95 DEG C. and the agent sprayed into the mass at normal, sub-, or super atmospheric pressures in a batch or continuous process.  Dusting agents such as kaolin, silica or diatomaceous earth may also be included.

Class 112 [Also in Group XXII] In a sewing machine thread tensioner comprising a fixed stud 18, a thread-engaging wheel 40 rotatable on the stud, and adjustable friction means carried by the stud for resisting the rotation of the wheel, the latter is formed from a pair of concentric annular members 50, 51. The periphery of each of which is formed with an annular series of openings 58, 58<SP>1</SP> defining radial fingers 59, 59<SP>1</SP>, each finger being disposed opposite an opening in the opposing member and being formed between its ends with an offset portion 60, 60<SP>1</SP> protruding through said opposite opening. A bush 11, secured to the sewing machine, houses the stud 18 secured thereto by a set screw 16. A check spring 23 has one end disposed in an axial groove 22 formed in an enlarged portion 21 of stud 18, the other end of spring 23 projects radially through a slot 14 in bush 11 and ends in a thread-engaging hook 25. Wheel 40 is disposed between two friction pads 41, the inner one abutting a fixed cup washer 26 and the outer one abutting a slidable pressure washer 28 biased inwardly by a spring 31 adjustable by a nut 32. A pin 62, axially disposed in stud 18, abuts a diameter bar 29 on washer 28, inward movement of pin 62 thereby serving to release the thread tension. Member 50 of wheel 40 is formed with a hub portion 52 journalled on stud 18 and with an annular groove 53 which initially produces an annular bead 54. Member 51 has a large central aperture 56. The members are clamped together and electrical current is passed to produce projection welding 54<SP>1</SP> therebetween along the bead 54. The fingers 59, 59<SP>1</SP> are inclined to one side to form the offsets 60, 60<SP>1</SP> of from <SP>1</SP>/ 2  to 1 times the thickness of the members 50, 51, are flared outwardly to form a peripheral groove which provides a sinuous path for the thread wound therein, and end in continuous rims 57, 57<SP>1</SP>. It is stated that, owing to this construction, the device, when once adjusted to impart the proper frictional resistance to one given thread, will impart without adjustment substantially the same frictional resistance to various threads having widely different characteristics.

A cross-head extrusion die intended for the production of thermoplastics rods, tubes and, more particularly, the coating of wires with thermoplastics, comprises axially movable coaxial mandrels 5, 9 and 15 which define compression zones 4a, 4c and an intermediate relaxation zone 4b. Mandrel 5 has a tapered end 6 whose external surface co-operates with frusto-conical surface 7 of die body 3 to define compression zone 4a, and is adjustable axially by rotation of a knob 8. In a similar manner, mandrel 9 defines the compression zone 4c and is adjustable by rotation of knob 13. Mandrel 15 is an axial rod (for tube extrusion) or a tube (for wire coating) and is attached to a hollow support 16 which may be adjusted axially by rotation of a knob 17. If a solid extrudate is required the outlet for mandrel 15 may be plugged so that it is prevented from protruding into orifice 4d. Chamber 4b is formed between compression chambers 4a and 4c to act as both a reservoir and relaxation zone. Die body 3 and nozzle 20 are heated, preferably by electrical resistance heaters (not shown) and in the case of wire coating it is mentioned that the extrudate may be air-cooled and water chilled. The die is sectionalized so that different frusto-conical surfaces 7 and 11 may be employed. Various thermoplastics are mentioned including PVC, polyethylene, polypropylene, polystyrene, nylon, polymethyl methacrylate, polycarbonates, P.T.F.E. and cellulose acetate, but the invention is particularly intended for the extrusion moulding of polyvinylidene fluoride.

Patent GB-440809-A (GB)
Abstract: 440,809. Colour photography. OPTICOLOR AKT.-GES., Glarus, Switzerland. July 3, 1934, No. 19615. Convention date, July 4, 1933. [Class 98 (ii)] In the process of reproducing lenticular original films on to lenticular sensitive films wherein both the original and the copy are developed by the reversal process, silver bromide solvents such as ammonia or potassium sulphocyanide which increase the resolving power of the sensitive layer are added to the first developer used in developing the copy, but such agents are not used, or are used in smaller quantities, in the first developer used in developing the original. Richer colours are thereby obtained. The quantities added may be still further diminished if the reproduction is performed by projection-printing through a colour-selecting filter the bands of which are separated by masks. Thin films with low content of silver bromide may be used for the originals. Specification 433,088, is referred to.

Title: Methods of affecting chemical heterogeneous phase reactions

Filed: 1960-12-28
Abstract: In effecting chemical reactions between a solid and a liquid in an annular simulated fluidized bed of Specifications 880,183 and 885,477 (wherein a revolving agitator keeps the solids in suspension independently of any upflowing gas) a solids discharge device is provided <PICT:0995843/C1/1> in the form of an axially adjustable pipe extending into the suspended solids, the pipe being cut open lengthwise in that part which is within the fluidized bed area, axial adjustment of the pipe permitting the convex exterior or concave interior of the lengthwise opening to be presented to the uprising solids, thereby varying the solids withdrawal rate.  As shown in the Figure, a vessel a is provided with a heat-containing jacket and at the bottom with rotating arms B which serve to maintain solids in suspension in the form of a ring-shaped bed, simulating a fluidized bed and indicated by the dotted lines.  Gas may be injected through a lower opening z whilst liquids and/or solids are fed through axial pipes f1, f2 on to the centre of a conical plate s surmounting and rotating with the beater bars B.  The solids withdrawal pipe is indicated by p, the lower half of which, in the position illustrated, has been cut away; uprising solids impinge against the concave interior of the remainder of the pipe and are deflected downwardly and outwards to a solids withdrawal pipe b.  The aspect that the slit pipe p presents to the solids may be varied by turning the pipe by handle h.  A downwardly directed flame may impinge on the centre of the conical revolving plate s, thereby distributing the heat around the annular bed. Reference is made to the application of the process to granulating ferrous sulphate monohydrate with tar and subsequently decomposing to form sulphur dioxide and iron oxide, decomposition of ores with sulphuric or other mineral acids, particularly chromium, niobium, tantalum or titanium ores, to the decomposition of ilmenite with liquid chlorine, and to the decomposition of fluorspar in stages to yield SiF4 and HF.
