Abstract: ABSTRACT     The invention relates to cross-linked conductive polymer compositions exhibiting PTC behavior, to methods for preparing them and to devices comprising them.             The invention is based on the discovery that, provided a sufficient degree of cross-linking is introduced, the cross-linking of any conductive polymer (whether crystalline or amorphous, and whether previously cross-linked or not) will have a substantial effect on the resistance temperature characteristics of the composition at a temperature which is related to the cross-linking temperature (which is frequently referred to herein as Tc), and/or at a temperature which is related to the temperature at which the polymer has previously been cross-linked.  Thus the invention makes it possible to prepare PTC compositions which have hitherto unknown resistance/temperature characteristics and/or physical properties, including PTC compositions in which a conductive filler is dispersed in an elastomer.            The new PTC compositions can be used in flexible strip heaters and other devices in which the temperature of a PTC element is used to control the size of the current flowing through an electrical circuit.

Abstract: ABSTRACT OF THE DISCLOSURE             A steam iron with a water tank, handle structure, ported soleplate, water valve assembly, thermostat control passing through the tank, and a fill opening in the forward handle portion to pass water through a riser tube to fill the iron is standard structure. To this is applied an improvement in the riser tube which comprises a single substantially cylindrical integral plastic member having an outer flange around its middle to rest on the tank with the tube extending down into the tank. The tube has a forward cut-away portion with the rear portion forming a baffle both being in the tank. The tube top is closed by a wall and a forward extension below the top wall is connected to the fill opening with an apertured baffle in the tube behind the extension. The top of the tube has a series of openings for selective use such as for self-clean or spray features and an operable stem extends through one of the openings connecting to the water valve. The riser tube has suitable vents and skirt extension to properly orient and lock the tube in position. Thus, a single integral plastic riser tube fills the water tank, it forms baffling in both the tank and fill opening for water retention, it has suitable vents to aid in filling and emptying and, it forms a guide for other selected features such as self-clean and spray that may be used in a basic iron.

Abstract: ABSTRACT OF THE DISCLOSURE   A computer system has two or more computer modules, each including an individual computer, a coupling memory and a working memory.  The modules can be coupled to a system bus comprising a control and address bus and a data bus.  Access is obtained to the coupling memory either from the system bus or from the individual computer by switching techniques, and only the individual computer has access to its working memory.  The system bus can be coupled to a control computer and a safeguarding memory, to which the control computer has access over the system bus, and a further memory, to which the control computer also has access, are provided.  The control computer, the further memory and part of the existing modules are employed to process the user's program, and a monitoring phase is inserted at regular intervals in which all the individual computers are checked for functional capacity by test programs stored in the working memories of the modules.  The fact that defec-tive modules are not found is stored in the safeguarding memory and normal processing continues.  If one or more defective modules are recognized, the same are replaced by other modules not used for processing the user's program and the individual function of the module replaced is loaded from the further memory which stores the entire user program into the replacement module before processing continues with the last safeguarded intermediate results stored in the safeguarding memory.

Title: Wind operated generator

Granted: 1981-02-17
Abstract: WIND OPERATED GENERATOR            ABSTRACT OF THE DISCLOSURE        Conventional generators normally stop in a posi-tion where maximum magnetic lock-up occurs.  This is no pro-blem under normal conditions.  However, when it is desired to operate a wind generator at a relatively low wind speed, then this lock-up becomes important.  Also, a small wind operated generator can reach excessive tip speeds in high wind conditions and if icing is a problem in the area where the generator is located, the centrifugal force can cause a severe vibration condition due to imbalance.  The present generator utilizes a permanent magnet in the rotor and has the rotor flux field arranged at an angle relative to the stator pole faces, thereby reducing the lock-up torque in order to allow rotation to commence at relatively low wind speeds of, for example, 3 and 5 m.p.h.  Furthermore, the braking effect of the generator holds down the tip speed of the fan so that the efficiency drops off thereby resulting in a smaller generator in order to obtain control of the fan speed above the rated r.p.m. thereof.

Abstract: BATTERY CHARGING CIRCUIT FOR      PORTABLE POWER TOOL     Abstract  of the Disclosure A battery charging circuit is operable for recharging batteries in both trickle and fast charge modes.  The fast charge mode is initiated and maintained by enabling a silicon controlled rectifier in circuit between a current source and the battery.  A capacitor maintains the SCR in the operative state until the battery reaches full charge.  A thermostatically controlled switch terminates the fast charge mode.  The battery is then trickle charged for an indefinite period.  Reversion to the fast charge mode is prevented by discharging the capacitor associated with the SCR when the thermostatically controlled switch opens.
