Abstract: ABSTRACT OF THE DISCLOSURE         Disclosed is an improved activation composition for preparing substrates for metallization in an electroless plating bath.  Also disclosed is an improved process for activating substrates prior to metallization and an improved process for metallizing employing the improved activating process. Electroless deposition, which involves chemically reducing ions of the metal to be plated from a plating bath and onto an activated substrate surface, is im-proved by employing an organic acid in the activating bath which activates the substrate surface.  Preferred activating baths contain palladium halide ions to provide a catalytic surface on the substrate, stannous halide ions to provide a protective sol, a source of additional halide ions, and an organic acid such as citric or tartaric acids.  The composition and process enable the elimination of a typically-required acceleration step, but yet provide consistently high quality results especially with substrates having through holes requiring coating, such as printed circuit boards requiring a plating of copper.

Abstract: ABSTRACT           Chilling apparatus especially adapted for airline food tray serving carts has a small blower at one upper end of the inside of the cart which exhausts air across a pan of dry ice or other cooling material removably positioned on an upper shelf of the cart.  Spacer means in the cart enclosure prevent the trays stacked therein from blocking a vertical air flow passage at each end of the cart.  Thus, the chilled air is directed downwardly from the pan over the inside wall of a door on the cart.  The chilled air then passes horizontally over at least a portion of the trays containing items to be chilled and is sucked upwardly along the other inside end wall of the cart to the blower inlet duet.  The apparatus is very light in weight and can provide sufficiently uniform cooling to the items on each tray which must be chilled when a container on each tray is being simultaneously heated.

Abstract: ABSTRACT OF THE DISCLOSURE     A verifying device for a key card on which a magnetic signal is recorded is formed of a set card on which a predetermined reference magnetic signal is recorded, a magnetic sensor consisting of a saturable core and a winding wound thereon, an oscillator for supplying a voltage to said winding, a switching element connected to the winding, a power source connected between both ends of the switching element, and an output terminal led out from one of both ends of said switching element.  In this case, the satura-tion magnetic field of the saturable core is so selected that it is larger than the magnetic field itself generated from the reference magnetic signal recorded on the set card in absolute value but smaller than the sum magnetic field of those from the set and key cards in absolute value when the key card is a correct card, so that when the correct key card is inserted into the device to be verified with the set card, the sum magnetic field becomes larger than the saturation magnetic field of the saturable core in absolute value, hence the saturable core is saturated, no output appears at the winding, thus said switching element is turned off and an output indicating that the key card is coincident with the set card is produced at the output terminal.

Abstract: ABSTRACT OF THE DISCLOSURE        To separate sheets from a stack, for example being fed upwardly, two separating stages are provided:  one separating stage is formed by a driven third feed roller (28) located immediately above a fixed separating element (30), for example a rubber block.  If, by chance, two sheets should be fed, the sheets are then fed to a second separating stage which includes a driven second roller (16) which, for example, may drive the third roller, and a first roller (20) therebeneath which can freely rotate in feeding direction.  It is secured to a shaft by a one-way clutch, preventing reverse rotation.   To impart limited reverse rotation to the first roller (20), the shaft thereof is rocked backwardly by an eccentric (50, 52) coupled to the shaft (18) which drives the entire apparatus. To feed sheets from a stack, the stack is height-adjustable by sensing deflection of the third roller (28) upon engagement with the topmost sheet of the stack, and controlling switching of an electric elevator motor, raising the stack, in accordance with sensed deflection.

Abstract: ABSTRACT:         Known radio transmission systems have base radio stations that form a cellular system in a geographical arrangement with overlapping radio zones.  At least one control channel and several traffic channels are allo-cated to the base radio stations.  In a radio transmission system with a large number of transmission channels the search by the mobile radio station for a control channel can take a long time if the channel does not lie in nar-row area of the frequency band of the transmission chan-nels.  To avoid long search times in any arrangement of control channels in the frequency band of the transmission channels references to other existing control channels, references to a substitute channel allocated to the base radio station and references by the control channel to itself are transmitted by the base radio station at vari-able time intervals.  The content of such references is at least the channel number allocated to the control channel or the substitute channel.

Abstract: ABSTRACT        A heat exchanger for heating air supplied to a burner is described.  The heat exchanger includes two passages.  One of the passages provides a channel  through which combustion gas is exhausted from the burner while the other passage pro-vides a channel through which air is supplied to the burner.          The two passages are arranged to transfer heat from the com-bustion gas to the combustion air.   Each of the passages in-cludes a helical guide baffle for directing fluid through each respective passage substantially along a helical  flow path.          The helical guide baffles of the passages each exhibits a var-iable pitch which changes at a predetermined rate to maintain the pressure and velocity of the fluid in the respective pass-ages within predetermined limits.

Abstract: ABSTRACT       Opening arrangements on packing containers are often of the type which comprises a prefabricated pouring opening.  The cut edges appearing around the pouring opening must be protected, e.g. for reasons of hygiene, from the liquid contents present in the packing container, and this is generally done by a liquid-tight strip applied to the inside.  A simpler manner of achieving this protection consists in ensuring that the thermoplastic layers which in general are present on both sides of packing laminate, extend past the cut edge      and are sealed in a ]iquid-tight manner to each other.  This can be achieved simplest if the hole-punching of the carrier layer of the material is done prior to the application of the thermoplastic layers.
