Abstract: Abstract:   The invention provides a panel for a roofing/siding system to overlie and cover a substrate.  The system comprises a number of such panels in side-by-side interlocking relation, and clip means for securing the panels to the substrate.  Each of the panels comprises a longitudinally extending pan having a pair of longi-tudinal edge portions.  One of the longitudinal edge portions is bent to form a lock seam and the other of the longitudinal edge portions is bent to form a batten, the batten being configured to cover the lock seam of the adjacent panel in the system.  The batten has a free end bent inwardly towards the pan and defining a lock lip.     The lock lip has a neck terminating in a lock head.  The lock seam comprises a three part bend including a trans-itional portion extending upwardly from the pan, an arch portion curving away from the transitional portion back and down towards the pan and a trough portion curving away from the arch portion and upwards from the pan.  The trough portion and the pan define a gap therebetween for allowing the head of the lock lip to be inserted between the trough portion and the pan.  The pan, the transitional portion and the arch portion define a receiving space in communication with the gap for receiving the lock head of the lock lip of the adjacent panel, the lock head being no larger than the receiving space, the gap being at least as wide as the neck of said lock lip.  The arch and the trough portions are accessible from above for the clip means to hook over the arch portion and down into the trough portion for securing the panel to the substrate and for preventing the trough portion from flexing relative to the pan.

Abstract: INVENTORS:  RAY STANYARD and HANSRUEDI LIECHTI          INVENTION:  CONVERTER-POWERED DRIVE FOR AN ELEVATOR                   ABSTRACT OF THE DISCLOSURE           A twelve-pulse converter has an a.c.-input and a d.c.-output which is connected with an armature via two thyristors of a charge-over circuit.   An extinguishing circuit comprises a resistor, a capacitor, an inductor and a thyristor which is also connected with the armature via related diodes.  A current transformer  in the armature circuit causes ignition of the thyristor in the extinguishing circuit  at  the  occurrence  of  excess  current.   The extinguishing capacitor is continuously connected with a charging circuit and is connected parallel to the thyristor of the extinguishing circuit and with the thyristors connected to the d.c.-negative pole.  The d.c.-negative pole connected thyristors are cut-off when the thyristor of the extinguishing circuit is ignited and the energy appearing in the armature circuit is dissipated by the resistor in the extinguishing circuit.  The zero-crossing of the current is detected by means of two voltage converters which are connected with the d.c.-negative pole and the d.c.-positive pole of the convertor as well as with the armature.  The non-current conducting thyristors which are connected either with the d.c.-negative pole or with the d.c.-positive pole, are ignited by means of information derived from the voltage converters.

Abstract: Abstract Process For Generating Steam In A Fuel Cell Powerplant The steam for a steam reforming reactor of a fuel cell power plant is generated by humidifying the reactor feed gas in a saturator by evaporating a small portion of a mass of liquid water which circulates in a loop passing through the saturator.          The water is reheated in each pass through the loop by waste heat from the fuel cell, but is not boiled.      In the saturator the relatively dry feed gas passes in direct contact with the liquid water over and through a bed a high surface area material to cause evaporation of some of the water in the loop.  All the steam requirements for the reactor can be generated in this manner without the need for a boiler; and steam can be raised at a higher total pressure than in a boiler heated by the same source.

Abstract: SAFETY SWITCH     ABSTRACT OF THE DISCLOSURE     A switch for providing a safety function when its main contacts are fused or stuck together in the "ON" position, com-prising a housing containing a pair of main contacts, one being designated an ON contact, and the other main contact being car-ried by a movable switch arm in the housing.   This switch arm has a first end which carries the movable main contact and a second end, and spring means mechanically coupled to the movable switch arm normally bias the movable main contact toward open position away from engagement with the ON contact.   Switch oper-ating means including movable actuator means overcome the biasing force of the spring means for moving the movable main contact to closed position into engagement with the ON main contact.  There are auxiliary safety contact means within the switch housing for completing a safety circuit and/or for deenergizing the main circuit in response to abnormal movement of the movable switch arm when the actuator means is moved to OFF position, but the movable main contact remains fused or stuck to the ON main con-tact.  In further embodiments, safety contact means become triggered and moved from a first to a second position for pro-viding a safety function, for example by closing a safety cir-cuit or by opening the main circuit, when the actuator means are moved to OFF position but the main contacts remain fused or stuck together in their ON relationship.

Abstract: ABSTRACT OF THE DISCLOSURE       A forced air, ambient temperature, evaporator coupled to an electroless copper plating bath and to a purification system for replenishing and maintaining the stability of the plating bath, which bath tends to become depleted as the result of the reduction of water soluble cupric salt in an alkaline solution under copper plating and reducing conditions and in which the rate of evaporation of water from the surface thereof is insuf-ficient to preclude growth in the volume thereof resulting from liquid additions thereto required to replace consumed constituents, thus giving rise to a need for bailout to prevent overflow thereof, solves the following problems:  evaporation is independent of plating bath geometry; very high evaporation rates enable bailout to  be zero at all plating loadings and plating thicknesses; the high evaporation rates provide sufficient cooling whereby the electroless copper solu-tion can be introduced directly to the purification system with no additional cooling; dragout losses may be completely eliminated; and the large amount of air blown through the electroless copper solution of the plating bath enhances stability by lowering the bath temperature, saturating the bath with stabilizing oxygen, and purging the bath of destabilizing waste hydrogen waste product.

Abstract: A smoke detector contains a pulse-operated radiation source and a radiation receiver arranged externally of the region directly irradiated by the radiation source. The radiation receiver, in the presence of smoke in the radiation region, is impinged by scattered radiation and delivers output pulses. There is provided an evaluation circuit which generates a blocking pulse, and which inputs a resetting signal to a counter device in consequence of the difference of the blocking pulse and output pulse of the radiation receiver. The counter or counting device, in the absence of a resetting signal, is switched further and upon reaching a predetermined counter state triggers an alarm signal. High-frequency electrical disturbances which arise, as long as the radiation source delivers radiation pulses, at most can generate an additional resetting signal for the counter, so that the integrity of the smoke detector against triggering of false alarms is enhanced. If there is connected in parallel to the radiation receiver a NTC-resistor, then there is obtained a smoke detector which responds to a further combustion criterion (temperature).
