Title: Improved process and machine for shrinking hat bats and like felt articles
IPC: D04H17/12
Filed: 1938-01-14
Abstract: 485,157. Hats etc.; felt &c. TRIGGS, W. W. (United States Hat Machinery Corporation) Jan. 14, 1938, No. 1291. [Class 63] [Also in Group VIII] The invention relates to a process and machine for shrinking hat bats and like felt articles. The machine produces a changing series of elevations and depressions from one edge of the article to the other while maintaining portions of the article between the depths of the depressions and the crests of the elevations free of pressure. The machine has a set of rollers A, Figs. 3, 4, supporting the bats 16 and a set B above the bats. Each roller includes a shaft 10 with spaced discs 11, 12 arranged alternately and internested, as it were, the disc of one roller extending into the space between the discs of the next roller. A single bat or a number of bats may be stacked one upon another in passing through the machine. Pipes 15 may spray the bats with boiling water. The operation on the bat is shown exaggerated at Fig. 7. Discs 11a form spaced apart elevations 16a and discs 12a depressions 17a so that the bat is transversely waved. Further progress of the bat reverses the process. The bats are repeatedly bent up and down and saturated with boiling water. This results in shrinking and interlocking the fur fibres. The discs engage the bat at spaced points only, the intermediate portions being free of pressure. The upper rollers B may be urged towards rollers A by springs 30 but their weight alone may be sufficient. The supporting rollers are positively driven and the upper rollers frictionally, but a direct drive may be given the rollers B.

A poppet valve stem 16 is guided for reciprocation within a bore 14 with which it makes a clearance fit by means of two axially spaced strips of material, e.g. wire, 40, 42 bent round the stem 16 and secured thereto, e.g. by being held in grooves 46, 44 cut in the stem; the thickness of that portion of each bent strip projecting from the stem being less than the clearance between the stem and the bore by an amount providing a predetermined sliding fit between the bore and the strip material. The poppet valve 18 on being moved to the left against a spring 35 serves to seat against a valve 20 thereby cutting off vacuum from a chamber 24 to the power chamber 30 of a servomotor, and continued displacement of the valve control rod 16 unseats a valve 20 to admit atmospheric air from a chamber 28 through a passage 36 of the rod 12 of a piston 10 to the chamber 30. The piston is then retracted by a spring 38 and remains so until the control rod 16 is released so as to allow the valve 20 to close and the valve 18 to become unseated.

Title: Improvements relating to the manufacture of moulding powders and moulded articles therefrom
IPC: C08J3/12
Filed: 1944-02-01
Abstract: A urea-formaldehyde resin syrup, prepared by refluxing and/or distilling urea and formaldehyde at atmospheric pressure and under acid conditions, is adjusted to a pH of 7-8, if desired concentrated by vacuum distillation, and spray dried into an atmosphere having an outlet temperature of about 100 DEG  C. and the resultant powder is dry mixed with dry filler and catalyst in the quantities requisite for a thermo-setting moulding powder. Lubricants and/or colouring matters may also be incorporated in the dry mix.  The mixture may be ball milled to intensify intimate dispersal of the ingredients.  In an example urea and aqueous formaldehyde (preferred molecular proportion 1-1.5 to 1-2.5) are refluxed together for 15 minutes, the pH then adjusted to 5.4 and some water removed by atmospheric distillation.  The syrup was neutralized with caustic soda, cooled to 30 DEG  C., reheated to 65 DEG  C. and fed to a spray drier with air inlet temperature of 150 DEG  C. The rate of feed was adjusted to give complete drying of the droplets before contact with the drier walls.  The air outlet temperature was approximately 100 DEG  C.  The dried powder which may be collected in filter bags or on a conveyer belt was ball milled with wood flour and zine stearate, cinnamic acid being also added during the course of the milling.

Abstract: 493,544. Refrigerating. PRESSED STEEL CO., Ltd., and KLEEN, N. E. AF. Jan. 22, 1937, No. 1909. [Class 29] Absorption machines and systems.-In apparatus of the kind comprising two units working on opposite phases to produce substantially continuous refrigeration, and employing a solid absorbent, e.g. strontium chloride, the generator-absorbers A, A<1> are provided with finned-jackets 17, 18 adapted, during absorp tion, to contain a vaporizable liquid to facilitate the dissipation of heat from the generatorabsorbers, said liquid, during generation, being forced out of the jackets through ducts 27, 28, disposed around auxiliary heating flues 29, 30 connected to the heating flues of the generatorabsorbers, into the upper parts of storage vessels 35, 36 having displaceable flexible diaphragms 37, 38. The lower parts of the vessels communicate through tubes 39, 40 with pockets 32, 31 respectively around the ducts 27, 28, the tubes and pockets containing a vaporizable liquid. During generation in the generatorabsorber. A, the. liquid from the jacket 17 is forced into the vessel 35 thus displacing the diaphragm 37 to the position shown, and at the same time the pressure developed in the pocket 31 displaces the diaphragm 38 upwards to force liquid into the jacket 18 of the generator-absorber A<1> which is passing through the absorption phase. Liquids such as aniline, nitrobenzol, cresol or xylol may be added to the liquid in the jackets 17, 18 to assist its ejection therefrom. Alternatively, an inert gas, e.g. nitrogen, may be added for this purpose. Further, the tubes 39, 40 and their associated pockets may contain an absorbent for the vaporizable liquid therein. The units include two-part condensers 43, 44 and 45, 46 communicating through heatexchangers 47, 48 with evaporators 51, 52. In a modification, the jackets 17, 18 may be connected to the opposite sides of a storage vessel having a central flexible partition. In another arrangement, the jackets 91, 92, Fig. 3, may be connected to storage vessels 93. 94 containing bellows chambers connected to thermostats 97, 98 containing an expansible fluid and disposed in contact with the absorbent in the generator-absorbers.

Title: Improvements in or relating to fluid actuated valves
IPC: F16K21/10
Filed: 1933-01-21
Abstract: 415,378. Fluid actuated valves; fountains. WILLIAMSON, F. E., (trading as WILLIAMSON & CO.), 13, Coupar Street, Dundee. Jan. 21, 1933, No. 1996. [Classes 69 (i) and 135.] In a valve which is opened by depression of its spindle G against the action of the fluid pressure on the valve member H, the closing of the valve is retarded by a diaphragm N connected to the valve H and forming a wall of an actuating chamber to which a portion of the controlled fluid is admitted when the valve is opened and from which the said fluid escapes past a leakage device P or Q into the valve outlet before the valve can close. Fluid is admitted to the actuating chamber by means of a spool 0, the upper flange of which has holes O<1> so that on depressing the head A which has a pin C working in a helical groove D, the rod B, the spool 0 and the valve spindle G are all depressed and fluid passes between the spool flanges through the holes O<1> into the actuating chamber. On releasing the head A, the bottom flange of the spool contacts the diaphragm and the trapped fluid can only escape through a cut P in the diaphragm seat or past a set-screw Q in the spool. In another form, the fluid assists in opening the valve and is admitted to the actuating chamber through the main valve spindle which in this case is hollow and controlled by a pilot valve located at its base. The pilot valve spindle is operated by a push button and carries a cross-pin which depresses the main valve spindle if the fluid pressure on the diaphragm has not already done this. The spool is dispensed with, and the set-screw is provided laterally in the main valve spindle which is clamped to the diaphragm. Both forms of leakage device may be used. The valve may be used in self-closing taps, or to control drinking fountains, or with ball and float gear as a cistern supply valve. Various forms of pilot valve are described in the Provisional Specification and reference is made therein to the use of a piston and to a form in which fluid escapes from the actuating chamber on operation of the pilot valve and gradually leaks into the chamber to close the valve.
