Title: Improvements relating to apparatus for charging paste-like substances into containers, e.g. jars, pots and the like
IPC: B65B39/12
Filed: 1933-02-10
Abstract: 415,091. Filling jars &c. with meat paste. SUTCLIFFE, T. C., 10, Charterhouse Street, STEPHENS, W. A., 73, Pennard Road, Shepherd's Bush, and HUXLEY, J. H., 10, Charterhouse Street, both in London. Feb. 10, 1933, No. 4172. [Class 125 (ii).] Relates to machines for charging jars &c., with meat paste, &c., of the type comprising a filling cylinder, a feeding tube, means for charging the cylinder, and a piston for forcing the contents into the jar, &c. According to the invention, means are provided for effecting relative movement between the jar and the tube to dispose the discharge end of the tube thereby, and to actuate the piston when the end of the tube and the bottom of the jar are in the prescribed relationship. Fig. 4 and 5 show a hand operated machine. A feeding tube 1 is slidably mounted in the diametrical bore of a disc member 2 which is rotatably mounted in a casing 3. Stops 7 limit the rotation of the member 2. The member 2 is swung alternately to the position shown in Fig. 4, in which the tube is charged with paste through a port 5 and then to the position indicated by the chain lines in Fig. 5. The paste is then discharged through a port 4 into the container C by an operating arm 9 fixed at 9a to the member 2. This arm is connected by links 11, 12 to the tube 1 and to a piston 10 which reciprocates therein. When the member 2 is moved in an anti-clockwise direction from the position shown in Fig. 4 the tube 1 and piston 10 move towards the container C ; the tube extending near the bottom thereof. The lost motion allowed by the slot 17 in the link 11 prevents the tube 1 from moving beyond the member 2 until the tube registers with the port 11. The arm 9 is now moved in a clockwise direction. The tube 1 is consequently retracted from the container after a pause allowed by the slot 17 while the piston 10 is advanced by the intervention of a catch 27 engaging a port 14 thereon. Paste is consequently extruded through the tube 1. The rate of withdrawal of the tube may be varied by making the arm 11 a toggle-lever working in a cam-slot. Suction may be applied during the filling operation through the conduit 19. Means may be provided for cutting off the suction when the tube is in register with the ports 5. In a modification the tube is charged through a measuring valve under a constant pressure, and is covered by a split-diaphragm which facilitates leaving a level surface in the container.

Title: Manufacture of polymerisation products of cyanamide and of artificial resins therefrom
IPC: C08G14/06
Filed: 1942-03-30
Abstract: Polymerization products of cyanamide, i.e. aminotriazines, are made by heating cyanamide or dicyandiamide with a mono- or polyhydric phenol until solid substances separate from the homogeneous melt first formed.  Suitable phenols include phenol, om- or p-cresols, xylenol, resorcinol and pyrocatechol.  The reaction product may be condensed with formaldehyde, if desired with additional phenol, preferably in a strongly alkaline medium, to yield resins.  Suitable alkaline catalysts are ammonia and alkaline earth hydroxides.  In an example, dicyandiamide and xylenol are refluxed for 1 to 2 hours. After cooling, the pasty mass is expelled from the vessel by air. Additional xylenol and formaldehyde solution rendered alkaline with caustic soda are added and the mixture heated at 80-85 DEG  C. for 1/2 hour. Water is distilled off and the homogeneous resin is mixed with fillers and a mould lubricant to form a moulding composition.
