Abstract: ABSTRACT OF THE DISCLOSURE        This invention relates to a frangible strip of clips and a method of making same.  The clips are used for closing bags containing bread, food produce and the like and the clips are made from laminar plastics material.          The strip is characterized by breaking portions at which each individual clip is separable from its longitudinal neighbours.  These portions are coextensive, longitudinally of the strip, with the line of separation which divides off each clip from its longitudinal neighbours and which is found without removal of material from the strip.  This line is achieved by shearing the material of the strip while bowing it about a longitudinal axis so as to present a curved surface to an oncoming shearing tool which has an oppositely curved surface.  The extent of intersection of the opposite curve defines the length of the line of the separation.  The breaking portion is adjacent each end of the line.  The clips during severance, suffer apparent lateral contraction but no longitudinal distortion.  This invention solves the problem of avoiding the production of chips of material or of snagging projections upon the separation of clips from the strip.

Abstract: ABSTRACT      The plant comprises a refrigerating system acting on the recycle air, including an auxiliary evaporator exposed to external air whereby the system may operate as heat pump.  The valves controlling the system have a position in which the auxiliary evaporator (50 E/C) is rendered operative while the dehumidifying evaporator (40) is rendered inoperative.  The outlet port (20) of the drying chamber comprises a by-pass section (20') which has associated therewith a first damper (46) by which the by-pass air flow is either recirculated to the condenser (38) or discharged to the outside through the auxiliary evaporator.  A second damper (44) is provided to admit external air to the condenser (38) when the first damper (46) connects the by-pass section (20') with the auxiliary evaporator.  Temperatures as high as 65-70°C are practically achievable in the manner in the drying chamber (10) by the effect of "heat pump"; the perfor-mance factor of the heat pump is extraordinarily high and may correspond to 5750 - 6000 Cal/kWh when the external air temperature is above about 15°C.

Abstract: ABSTRACT OF THE DISCLOSURE     Before a main wall is prepared by pouring concrete, a profile element with anchor steel rods extended through its bottoms is fitted to a planking in such a way that a cavity is created between the bottoms of the profile element and the planking. The profile element has two side walls and two bottoms lying in the same plane. The anchor steel rods extended through the bottoms form U-shaped loops on the one side of the element, whereas the end portions of the anchor steel rods bent in right angles from the legs of the U-shaped portions lie on the other side of the element. The surface of the profile element is roughened and its side walls enclose each a sharp angle with the bottoms. By means of the profile element locked in the concrete of the completed main wall a groove is formed in the outer face of the concrete main wall out of which groove the end portions of the anchor steel rods can be bent outward without additional works, such as scratching-out of a plastic body as per the prior art. In this way also the adhesion ability of the connection place in the completed concrete main wall for the bondage of another structure to the main wall is enhanced.
