Abstract: 516,825. Water-heating systems; heating buildings. MARGOLIS, A. E. July 11, 1938, No. 20470. [Classes 64 (i) and 64 (ii)] In district hot-water supply and heating systems, water heated to a temperature above that required for domestic supply flows from a main 1 to a supply system 15 in a house through a pipe 2 containing a heating coil 4 in a calorifier 3 through which circulates the water of the house heating system 5. The temperature of the water in the respective systems may be raised by an electric heater 7 in the calorifier and an electric heater 12 in a storage tank 10. The temperature of the water in the supply system is regulated by a thermally operated valve 13. The water from the main may flow directly to the house supply system, the flow through the heating coil being cut off by valves 18, 19. In a two-pipe system, the return flow is regulated by a valve controlled in accordance with the temperature of the water in the heating system. Water after passing through the heating coil 4 may flow into a storage vessel supplying a second heating system, and the supply system 15 may contain a storage vessel in which the water is heated by the hot water taken directly from the main.

Abstract: 1496735 Transferring textile cops between conveyers OFFICINE SAVIO SpA 19 May 1975 [10 June 1974] 21347/75 Heading B8A [Also in Division D1] Apparatus for conveying textile cops comprises an upwardly inclined conveyer belt having one-cop compartments, a horizontal or downwardly inclined conveyer belt which starts where the first conveyer belt ends and which has one-cop compartments formed by separator means movable so as to lie beneath the plane of the conveyer belt, means for driving the conveyer belts in step-by-step fashion so that when stationary two compartments coincide to enable cops to be transferred from the first to the second conveyer belt, and an intermediate storage position arranged above and parallel to the second conveyer belt for storing aligned cops. To feed cops from container 11, Fig. 1, to usage point 32, cops are carried on belt 12, Fig. 2, and by shoot 13 into reservoir 17. Belt 15 is moved step-by-step by device 34 to raise the cops in one-cop compartments 18. The cops are transferred to one-cop compartments 25 of belt 19 advanced step-by-step by device 34, and transferred again so that their ends lie between guides 29, 30 feeding the usage point. Means 14, e.g. a photoelectric device or mechanical feeler, controls belt 12 to control the number of cops in reservoir 17. Compartments 18 are formed by lateral means 20 which have slits and whose heights may be adjusted so that the ranging heights of the means 20 causes misaligned cops to fall down the conveyer and into an empty compartment. When belt 15 has moved one step the slits in a means 20 coincide with the teeth of a lateral means 21 defining a compartment 25. A cop then rolls into belt 19 which then moves forward one step with the belt, and cam 28 pivots the means 21 upward on the belt to form compartment 25. The cop is carried along guides until meets resistance, e.g. a csp in the guides, when the means 21 is pivoted downwards, against spring- or magnetbias, and moves beneath the cops. Feeler 43 may be raised by jack 45 to pass through the slits in means 20 to cause the cops to fall backwards. Means 40 moves the cops axially toalign one end against a stop. Maximum and minimum level feelers 38, 39 control belt operation to maintain the number of cops stored at 22. The cops may fall from belt 15, Fig. 5, outer belt 19, which may be horizontal. To control cop feed, reservoir 17 may be fed by a succession of separately controllable belts.
