Inventor: CANCIO L V
IPC: B29C51/00
Filed: 1979-03-26
Abstract: Plastic films or sheets having tear lines formed therein are disclosed. These films are made by forming a score along a predetermined line in the surface of a plastic film to form a tear line and then restoring the scored film surface without eliminating the line of tear. The products tear very easily along predetermined lines even though the restored plastic films have enhanced impact strengths. By restoring the surface of the scored film, score lines become invisible to the naked eye and the useful life of the film is extended. Single-ply or multi-ply products are disclosed including products having an embossed or textutred surface, still without eliminating the capability for a smooth line of tear. The products have many utilities as structural materials which may be sized or torn by hand, including wall coverings, window shade coverings, rupturable packages and envelopes, to mention a few.

Abstract: In manufacturing a telecommunications cable which comprises a plurality of insulated conductors enclosed within a sheath and with the interstices between the conductors filled with powder of a material which expands if it absorbs water (to form a blockage against passage of any ingressing water along the cable), the individual conductors 2 pass through a tapering cavity to converge and become stranded together and the powder is thrust towards the narrower, exit end of the cavity by a helical screw 20, thus forcing the powder in-between the conductors. In another embodiment (Fig. 5 not shown) the cavity does not have a helical screw but the feed hopper does. <IMAGE>

Abstract: A process and apparatus for casting semi-finished metal products in which a molten-metal-proof-plunger (27, 100, 161, 163) is disposed near the top of a cavity (26, 162, 164) in a permanent mold (20, 150),a reservoir (36, 203) of molten metal is created and maintained over the plunger, and the plunger is caused to descend in the cavity at a controlled rate so that the molten metal (35) enters and fills the cavity above the plunger. When the plunger reaches the bottom of its descent, a cast product of uniform cross section is formed. As the cast product cools and solidifies, the plunger is preferably used to exert an upward force to the casting which may cause the top of the casting to project slightly out of the mold as it cools.

Abstract: The invention refers to a method and a device for forming concrete pipes (13) through subjecting concrete (4) in a mould (1) to vibration and pressure. The purpose of the invention is to ensure that the concrete pipe retains the aimed at quality and/ or predetermined length and according to the invention this is done through controlling the vibration frequency to be less during the last part of the mould (1) filling with concrete (4) and to again be greater during formation of a tapered end (14) in the concrete pipe (13). A simple and effective device for carrying out this method is comprised therein by a control tool (16) designed in order to reduce the vibration frequency in a vibrator (3) through reducing the rev count in a drive aggregate (6) for the vibrator (3) when the concrete (4) has reached a certain level under the upper edge of the mould (1) and that another control tool (19) is arranged in order to increase the vibration frequency in the vibrator (3) through increasing the rev count in the driver aggregate (6) when tapering (14) of the concrete pipe (13) occurs.<IMAGE>

Abstract: A volume flow meter for the measurement of the flow quantity of a liquid, which meter comprises a cylindrical flow channel (3), which has an inlet point (10) and an outlet point (12) for passing the liquid to be measured through the measurement channel. In the measurement channel, there is an axially moving, spring-loaded indicator piston (4), which is shifted by the liquid in the measurement channel into different positions depending on the flow quantities. In the wall of the measurement channel, there is an outflow slot (27) for the liquid, which slot becomes deeper from the inlet point to the outlet point. The meter is provided with a reversing valve (17), so the flow of the liquid to be measured can be guided through the by-passing channel (26) to the opposite side (3') of the indicator piston (4), as seen from the inlet point (10), so as to shift the indicator piston towards the inlet point. This movement of the indicator piston wipes the wall of the measurement channel clean from impurities. In the indicator piston, there is a flow connection from the opposite side of the piston to the outflow slot of the measurement channel.

Abstract: A method of flue-gas cleaning comprising the separation of water-soluble substances from flue gases containing water vapour. The invention is characterized in that the flue gases are caused to be cooled by direct contact between flue gas and atomized water in two or more separation steps, where in a separation step (2) subsequent in the flow direction of the flue gases the flue gases are cooled by atomized water to a temperature, at which the water in the flue gases is condensed out, which water is collected and thereafter both recirculated for utilization in said subsequent separation step (2) and introduced into a separation step (1) prior in the flow direction of the flue gases. In said prior separation step the water is atomized and meets uncleaned flue gases, the water-soluble and potentially water-soluble substances of which thereby are solved in the atomized water. The water thus impurified is collected for further treatment.
