Abstract: The present invention relates to an injection method and apparatus for carrying out the method in a hot chamber type die casting machine for injecting and filling melting metal or so-called molten metal stored in a retaining furnace into a mold in a system of a thermally pressurizing chamber to cast and mold metal products, wherein brought into communication with a drawing-up cylindrical body stood upright with a lower opened end dipped into the retaining furnace is an injection cylindrical body with one opened end connected to a sprue of a mold to form a cross-shape sleeve, by which molten metal within the retaining furnace is drawn up outside the retaining furnace by a suction force, and the thus drawn-up molten metal is injected and filled into the mold by a pressing force.

Abstract: The present invention relates to methods for measurement and detection which employ a photosensitive indicator which may be prepared from a composition capable of offering a visual, calibrated reaction to the presence of ultraviolet radiation. The indicator preferably employs a composition comprising a complex of a leuco dye and animal-derived serum albumin. The leuco dye-serum albumin complex is capable of exacting calibration, so that scientifically significant quantitative measurements of radiation falling within the wavelengths of ultraviolet light and lower may be made. Numerous techniques useful in a variety of diagnostic applications are made possible, including the measurement of bioactive materials that are independently capable of absorbing ultraviolet wave energy, as well as bioactive materials that by association with certain ancillary materials capable of modulating their ultraviolet light absorption may similarly be quantitatively measured.

Abstract: A webbing brake is coupled to the retractor frame and has a hinged brake member with a finger which rides the outer convolution of the seat belt on the spool, the brake member having a portion which, as the spool fills with webbing, becomes so inclined that it frictionally engages a face of the seat belt and restrains its rate of retraction onto the spool.

Abstract: A method for the preparation of selectively decorated resin films comprises applying a first primer coat to the entire area of the base film, then applying either a masking coat alone or one or more color coats followed by the masking coat, the masking coat applied to an area of the base film that will define the final selective decoration. The masking coated surface is thereafter metalized and the resulting composite is joined to a mask-removing film bearing a pressure-sensitive adhesive having a limited peel strength known as "soft peel". The process is completed by the separation of the respective films, with the mask removing film withdrawing from the base film the unwanted portions of the metal coat and its underlying masking coat, to leave a crisp, patterned decoration.The present process requires no solvents and is therefore environmentally preferred.

Abstract: The invention provides a machine for manufacturing and handling tea bags, wherein the tea bags are produced by laminating together two webs with individual quantities for tea therebetween. Two rows of tea bags, formed in the webs, and the tea in the bags is biased upwardly of the webs. This is followed by severing of the webs into two individual single tea bag row webs, and this is followed by transverse severing of the web to produce individual tea bags. The tea bags are held into magazines so as to form two stacks therein and stacks of tea bags are moved laterally of the magazine into the inserting device and the inserting device places the two stacks of tea bags into a carton. The two stacks of tea bags are placed together prior to insertion of the carton and extra conversion is given to the stacks to compensate for revising the tea.

Abstract: Apparatus for the continuous hot tinning of printed circuit boards includes conveying rollers for passing the circuit boards through the apparatus, and a trough for accommodating the molten tin, together with nozzles for applying tin from the trough to appropriate locations on the circuit boards. A hollow column is disposed at at least one side and preferably at both sides of the path of conveying movement of the circuit boards through the apparatus, with the open lower end of the or each column dipping into the trough so as to be below the level of the molten tin therein. Tin is pumped from the trough through the columns by pumps at the lower ends thereof, and then to the nozzles arranged above and below the path of conveying movement and directed so as to spray molten tin on to the printed circuit boards. In a process using the apparatus for soldering the connecting pins of components to a circuit board, molten tin from a trough is sprayed against the underside of the board at the appropriate locations.
