Abstract: Method and apparatus for storing of heat by use of the heat of fusion or crystallization of a liquid-solid storage medium. A conventional crystallization roller rotates with its circumference partially immersed in the melted storage medium. Heat receiving liquid circulated through the drum to a point of use receives heat from melted storage medium in contact with the drum, whereby such storage medium solidifies on the surface of the drum. The drum rotates the solidified storage medium past a fixed scraper which transfers the solid storage medium to a heat exchanger. Heat supplying liquid circulating through the heat exchanger imparts its heat to, and melts, the scraped-off storage medium which returns to the storage medium reservoir and brings with it the heat obtained from the heat supplying liquid.

Abstract: A radio receiver (10) having a tuned IF stage (20) which is followed by a detector stage (24) producing an output representative of the change in frequency of a signal applied at its input. A predetermined frequency alignment signal (80) and a white noise source signal are alternately switched through the IF amplifier stage (20) of the receiver being aligned. A series connected integrating capacitor (50) and a tuning meter (60) are coupled between the receiver's detector output (24b) and ground potential (70). 
<??>In operation, during the interval of white noise being applied to the IF stage, the tuning meter (60) is shorted (40, 44, 46) and the capacitor (50) is charged to a net voltage Vn which is representative of the center frequency of the IF. When the alignment signal is applied to the IF stage, the tuning meter (60) short is removed and a signal Vs appears across the capacitor-meter circuit, whereby the meter reading is indicative of Vs-Vn which represents relative receiver alignment.

Abstract: Dust precipitator housings in light-weight construction for suction hose filters are provided especially with a circular-cylindrical base shape. Such dust precipitators operate under an internal vacuum, so that atmospheric pressure bears on the outside of the housing and stresses it. Corresponding to the high stress, these dust precipitator housings are built of cylindrical shells having a wall thickness of a few millimetres. In order to avoid correspondingly great weights for large filters of several metres diameter and nevertheless to obtain the necessary rigidity of the housing and also to produce such thick-walled components and economically to utilise the moulding machines required for this purpose, it is proposed that, in such a dust precipitator housing, at least individual wall sections (2 to 5) are made of relatively thin plate or strip materials (7) stiffened by profilings (6), that the wall sections (2 to 5) are formed from closed and tensioned rings (8) which overlap at each joint (9), and that a plurality of wall sections (2 to 5) are secured by supports (11) against bending, bulging and similar stresses. The plates or strip materials (7) are here made of thin, profiled steel sheet of a material thickness of less than one millimetre. The profilings (6) are corrugated, trapezoid or triangular, and reinforced by flanges if required. The supports (11) and the wall sections (2 to 5) are mutually joined by means of screws (13) or rivets penetrating both, and the screw holes (18) and riveted joints are made with a seal. A process for assembling the housing is also described. <IMAGE>

Abstract: A system for controlling registration in a printing press between a moving web (10) having repetitive print patterns and a work station (19) operated cyclically in synchronization with the press. The system includes a photoelectric scanner (16) having a variable sensitivity, a position pulse generator (39) with a backup accumulating device, a motorized compensator (13) for controlling the longitudinal position of the web (10) relative to the work station (19) and a digital control system (34) for driving the compensator (13) to correct misregistration. The control system (34) counts position pulses during each cycle of the work station (19), defines a monitoring period during which marks (30) on the web (10) are scanned, and signals differences between the cycles of the print markings and the work station (19) by sampling, at the occurrence of each mark (30), a digital number which corresponds to the instantaneous position of the work station (19) and its cycle. To enhance selectivity the system employs a variable sensitivity scanner, a variable duration monitoring period or window and automatic setup apparatus that synchronizes the system to those portions of the web (10) which are most distinctive and uncluttered.
