Abstract: Drinking water from the first system (4) flows into a tank (2) and, with non-return valve (37) open, into a chamber (32) of a pump (3) expanded by springs (34) acting against a first diaphragm (32a). A dropping of the pressure in the second system, for example a heating installation (1), brings about an opening of a valve (17a), and, if a time-controlled valve (26a) and a valve (28a) which is open when there is low pressure in a line (9) are open, brings about a throughflow of the control space of another valve (8), opening the latter. Drinking water can flow through the open other valve (8) via the line (9) into the tank (2) and a second diaphragm (33a) can be pressed via an intermediate piece (42) against the first diaphragm (32a). The water in the chamber (32) is thereby pumped via a further non-return valve (18a) into the heating installation (1). The separation of the drinking water from the water of the heating installation is complete. A return flow is not possible. The installation is operated exclusively by the pressure energy of the drinking water and requires no auxiliary energy as in the case of known installations. <IMAGE>

Title: Automatic reel for continuously winding bandform material - i.e. film, foil, paper, in definite lengths, smoothly and neatly
Inventor: SKACEL STEPHEN JAN DIPL ING
IPC: B65H19/22
Filed: 1975-05-27
Abstract: A fully automatic reeling machine for winding continuous bands of matl., esp. films, and foils of synthetic matl. or aluminium, flattened extruded tubular film, paper or combinations of any of these, esp. perforated bands of household purposes, etc., draws definite lengths from a supply reel and rewinds them on tubes of pulp or similar, arranged in a revolving head. The supply reel is driven by a pressure roller and the workpiece is drawn over a roller, round a tension compensating roller and over a rubberised guide roller with its associated driving roller to the reel tube. At the six reel stations on the revolving head, the driving spindles are all rotated by a common driving wheel which engages through a clutch only with the spindle of the reel in contact with the tension compensating roller at the winding point. Alternatively a cam disc and levers may be fitted to lift the reel driving shafts out of contact, except at the 1st winding station. Before the empty tube from the magazine reaches the 5th winding point, adhesive is applied, and immediately following the completion of the winding of a full reel, the head turns for the taut bead to be sheared and simultaneously pressed on to the new reel. On the end face of the driving roller, a tooth segment arrangement signals via a photocell that the required length has been wound on, and during the momentarily slowing down at the winding station, the balancing roller takes up the slack. The full roll moves round to the unloading point (i.e. 3rd station) where it drops on to a chute and rolls into a carton on the packing conveyor. Three different revolving heads can be assembled in the same frame. Delicate and more robust matls. can be allocated to the appropriate system allowing diversification. A machine can be installed with one head for an addn. to be made later. Different widths can be wound on the same machine, only the heads having to be changed.
