Title: Method and apparatus for producing packages of plastic material at high cyclic rates
IPC: B65B25/06
Filed: 1957-05-10
Abstract: 831,662. Moulding margarine &c. CHEMETRONCORPORATION., [formerly NATIONAL CYLINDER GAS CO.]. May 10, 1957 [May 18, 1956], No. 14981/57. Class 87(2). [Also in Group XVII] Margarine expressed into a moulding chamber 151, Fig. 12, in a boss 149 forces inwardly a moulding block 190 which is connected to a moulding block in a similar moulding compartment in a boss 148, Fig. 11, diametrically opposite the boss 149 so that it pushes a previously moulded block of margarine out of this compartment. In the construction illustrated the moulding blocks are joined by a threaded sleeve 157 engaging threaded portions 156, 160 on piston rods joining the moulding block so that rotation of the sleeve 157 by worm wheel 159 driven by a worm 162 adjusts the volume of both chambers simultaneously. The shaft 163, Fig. 8, is turned to effect this adjustment whenever a corresponding push button 133, 134 is pressed to place a projection in the path of a star wheel 164 on the shaft 163. Catches 174. 183 normally locking the moulding blocks are withdrawn in timed relation with the rotation of the drum 22. Four pairs of diametrically opposite moulding compartments are preferably provided axially spaced along an intermittently rotating drum 22, Fig. 11 through slots in which the margarine is expressed from a header 67 to several outlets in a manifold feeding the moulding machine. Tow drums 22 are preferably mounted side by side and driven by splined engagement with a sprocket wheel between them. The drive to the moulding apparatus is controlled according to the supply of material available from the header 67. As shown in Fig. 3, the pressure of the margarine against a piston 81 is balanced by liquid or pneumatic pressure on the underside of the piston controlled by the back pressure in a circulating system (not shown), and upward movement of the piston 81 is caused, through a piston rod 86 controlling a switch 79, to interrupt the drive to the moulding machine if the supply of margarine fails. The header 67 is supplied from two chambers 65 and 66 mounted one on each side of the chamber containing the piston 81 and fed through sleeve valves 71, 72 mounted on a rotating shaft 70 so that one of the valves is open at any given moment. The blocks of margarine are subsequently wrapped as described in Group XVII.

Title: Improvements in the manufacture and production of resinous condensation products
IPC: C08G4/00
Filed: 1933-05-25
Abstract: Resinous condensation products are prepared by heating cyanuric acid in the presence or absence of other substances capable of forming resins with formaldehyde with formaldehyde in the presence of a diluent at temperatures not exceeding 160 DEG  C. until dissolution has taken place and then removing the diluent under reduced pressure. Acid condensing agents such as hydrochloric acid or acetic anhydride may be used.  Other substances that may be added include urea, thiourea, aromatic amines such as aniline, toluene sulphonamide and phenol.  The products are soluble in water and organic solvents such as acetone, cyclohexanone, dioxane and glycol monoalkyl or monoaryl ethers.  In examples, cyanuric acid is condensed with aqueous formaldehyde under various conditions of acidity, the product, if desired, being condensed with further quantities of formaldehyde; (8) cyanuric acid is condensed with formaldehyde in the presence of dioxane; (9) cyanuric acid and formaldehyde are condensed with urea or thiourea.

Abstract: 200,075. Cleveland Metal Products Co., (Assignees of Chadwick, L. S.). June 29, 1922, [Convention date]. Wick burners, annular; flame spreaders and deflectors.-An air distributor or flame spreader comprises a tubular central element 10, a second tubular element 30 surrounding it and connected with it at its upper end, the element 30 carrying a flange 35 in spaced relation to the wick and also carrying a third short tubular element or body 40 surrounding it, disposed beneath the flange and fitting within the inner wick tube. The element 30 has openings 77 adjacent to the body and openings 75 in the plane of the space between the flange 35 and an upper flange 26 which forms a top portion 20 secured to the central element. A frame 50 depending from a span member 5 which also supports the spreader has pivotally connected locking elements 51 which are engaged over an abutment 16 of the central element 10 when positioned by a pin 55 slidably supported within the upper end of the central element. When the burner is in use, air currents rise through openings in the span member into the elements 10, 30 and out through openings 70, 75 and the restricted passage between the flanges 35, 26, the resulting thin air stream imparting suitable shape to the flame and shielding the top. A central current escaping through perforations 85, 84. 83, 86 prevents undue convergence of the outer current and heating of lifting means 56 of the pin 55. Currents which pass into the body portion 40 of the spreader, being deflected by the abutment 16 through openings 77 are mainly directed downwardly beneath the spreader flange by the baffle 60, and the space between the wick and body portion is supplied with air through peripheral openings in the span member for preventing the descent and condensation of vapours therein. Specifications 200,076, 206,545, 213,293, and 213,345 are referred to.

Title: Smoke condensing and water heating device
IPC: F24H3/08
Filed: 1950-06-19
Abstract: 685,154. Tubular surface condensers. WALDON, C. D. June 19, 1950. No. 15325/50. Class 64 (iii), [Also in Group XXVIII] Smoke from a furnace is drawn by a fan 13 driven by a variable speed, temperature-controlled motor from an inlet 11 to an outlet 14 to be progressively cooled and condensed as it passes through a number of heat transfer sections. A cast, end header 2 of the top section is connected, by spaced water tubes 3 over which the smoke passes, with an opposite header 1, each header comprising a number of units, side by side as shown, to attain the required length. Return water from a hot water heating system passes into the top section through an inlet 4 then, after passing through the top tubes 3, flows by an outlet 5 to a boiler heated by the furnace. Baffles 12 rest on the tubes 3 to direct the smoke in a sinuous path. Ports on the sides of the header units register for intercommunication of the units, but those units at the ends of the rows have the ports in their exposed sides sealed by plugs 8. The remaining sections are of similar construction. Water from a tank passes through the middle section and from a composite end header 9 back to the tank which is used as a source of hot water. Cold water passes through the bottom section and passes from a composite end header 10 to waste. The casing of the device has doors 15 at the top and front to facilitate the removal, for chemical industrial purposes, of solids and liquids deposited from the smoke which may be further purified in the device by sprays or screens. When coal is used to fire the furnace, coal gas is led from the outlet 14 to a burner.
