Abstract: An auxiliary power source comprising a generator driven by an electric motor or other drive means, the rotor of the generator has multiple core elements mounted side-by-side to provide a large number of poles and accordingly, a relatively high output frequency. Specially dimensioned pole faces eliminate cyclic air gap reluctance variations as an audible noise source.
Abstract: A turbine type flow meter incorporating an auxiliary turbine ahead of the main turbine, the auxiliary turbine rotating in the opposite direction from that of the main turbine and serving as a flow conditioner, thereby extending the effective range of the flow meter to lower rates of flow.
Abstract: A novel combination is disclosed comprising a container for liquids and a stand. The container comprises a hollow container body with an upper end and a lower end. The upper end has a neck portion having an opening therethrough whereby a removable cap attaches to the neck portion for sealing and unsealing the opening. A top is joined to the upper end of the container body whereby the joined top and body simulate a football. The lower end of the body is removably mounted to the stand, the stand simulating a football tee. The stand comprises a U-shaped portion having a base and arms extending laterally therefrom, with the base further having a notch centered therein. The notch receives the lower end of the body. The stand further includes legs mounted on each arm opposite said base, the legs extending upwardly therefrom to engage and support the body.
Abstract: This invention discloses a versatile power and control circuit for an electric door strike that is operable in four different modes with readily adjustable release times. In addition, the invention is directed toward the provision of a highly efficient power supply that permits miniaturization and prevents overheating in the confined space that is available for installation in a door jamb.
Abstract: A racer toy in which a pair of flat-bottomed boats each having an interior chamber which terminates in an opening at the aft end of the boat are launched onto respective side-by-side tracks from a launching tower having two water passages each extending from a source of water under pressure, such as a garden hose, to a respective nozzle dimensioned to be releasably held in sealing engagement within the aft opening of a respective boat. Each water passage is initially closed by a hand-operated valve which when opened allows pressurized water to flow into the interior chamber of a respective boat and thereby propel it along the track. The tracks are lubricated with water to reduce friction and to cause the boats to hydroplane as they speed along the tracks.
Abstract: A mounting fixture for a hand-held electric hair dryer comprising a base with a support surface and a hollow collar extending perpendicularly therefrom; an elongate rod supported within the hollow collar; and clamping elements on the upper end of the rod. The clamping elements include two planar clamp pads mounted in two dish-like members. The clamping elements are spring biased to accommodate the hair dryer therebetween. The spring bias is achieved either by a yoke formed of spring steel or by two pivotally secured flat members having a compression spring located between adjacent ends of the flat members. The direction of the barrel of the dryer and accordingly the direction of the column of warm air exiting from the barrel can be easily adjusted horizontally and vertically over a wide angular range allowing a user of this type of hair dryer free use of both hands while drying hair.
Abstract: An asbestos replacement is disclosed which includes water retention agents and finely divided mineral clays with high moisture retention capabilities. Combining the aforementioned ingredients in the correct proportions yields properties as those of asbestos when used in cementitious mortar compositions.
Abstract: A permanent magnet generator or motor having stationary coils positioned in a circle, a rotor on which are mounted permanent magnets grouped in sectors and positioned to move adjacent said coils, and a carousel carrying corresponding groups of permanent magnets through the centers of said coils, the carousel moving with the rotor by virtue of its being magnetically coupled therewith.

Abstract: A tubing assembly is disclosed for use between an exhalation valve and a ventilator for providing assisted breathing to a patient. The ventilator has a patient air outlet, a exhalation valve control outlet and a sensor outlet connected to a sensing mechanism. The exhalation valve has a first outlet to a tracheotomy connector, a second outlet to ambient atmosphere, an inlet and a control air inlet. The exhalation valve is switched between an inhalation position and an exhalation position by air pressure at the control air inlet. The tubing assembly comprises an exhalation valve connection, a ventilator-sensor connection, an intermediate tube, a sensor tube and an exhalation valve control tube assembly. The exhalation valve connection is attached at one end to the intermediate tube and at the other end to the inlet. The ventilator-sensor connection is attached at one end to the patient air outlet and at the other end to the intermediate tube.
Abstract: An assembly of parts which form a stud for construction use. This stud assembly greatly reduces the material content of the stud assembly and reduces heat transfer and noise transmission over the known prior art and comprises two parallely arranged U-shaped channels interconnected by a novel mesh connector which interconnects the channels at one or more points along their length and is expandable only in a direction transverse to the longitudinal axes of the channels.
