Abstract: A battery charger for incorporation into an electric-powered vehicle is disclosed. The charger includes a ferroresonant voltage-regulating circuit for providing an output voltage proportional to the frequency of an input AC voltage. A high frequency converter converts a DC voltage supplied, for example, from a rectifier connected to a standard AC outlet, to a controlled frequency AC voltage which is supplied to the input of the ferroresonant circuit. The ferroresonant circuit includes an output, a saturable core transformer connected across the output, and a first linear inductor and a capacitor connected in series across the saturable core transformer and tuned to resonate at the third harmonic of the AC voltage from the high frequency converter. The ferroresonant circuit further includes a second linear inductor connected between the input of the ferroresonant circuit and the saturable core transformer.

Abstract: The disclosure relates to a rotary indicating device preferably in use, for example, for wheel covers for motor vehicles. The device includes a base member having an indication region and adapted to be rotated about a rotary axis. The indication region indicates a desired image and comprises a plurality of reflection faces. The reflection faces are inclined in the same direction and also at the same angle with respect to a standard plane perpendicular to a rotary axis of the base member. Thus, when the base member rotates, the observer can visually recognize the image as a clear single image due to the after image phenomenon.

Abstract: Disclosed is a pulsed electron beam gun for generating a high current, short duration pulse which is received by a pulse detection circuit. The gun has a gated electron beam emitting area, a beam deflection and sweeping area and a beam pulse detector. Magnetic collimating means having lines of force along an axis in the direction of the electron beam surrounds the aforementioned structure. The magnetic collimating means intensifies the density and strength of the electron beam once it is emitted from its source of emission and is gated through the electron gate. A conventional pulse source delivers a low voltage pulse and a delayed pulse. The internal impedance of the pulse source is matched at the location of the electron gun where the pulses are applied to the electron gun components. The first pulse, at the beam gate, causes a short burst of electrons to be emitted.

A first heating device, a recirculating fan and a gas purge device are provided in the charge chamber, while a second heating device is provided in the heat treating chamber supplied with the protective atmosphere, whereby the work is preheated through convectional heat transfer in the charge chamber simultaneously with high-temperature purging of the charge chamber and then, is heat treated under the protective atmosphere in the heat treating chamber.

Abstract: An illegal-sheet-material detecting apparatus, which is adapted to detect whether the property of each of the passing sheet materials is legal or not in a sheet manufacturing machine, provided with a comparison circuit for detecting the lag of the same detection value of the n th+ first sheet material with respect to the detection value showing the property such as thickness, size or the like of the optional portion of the n th sheet material memorized in the memory circuit as an electric signal. When the lag detected by the comparison circuit has exceeded a predetermined range, the counting operation of the sheet material is caused to stop thereby to use the detection value of the n th sheet material as a reference value for comparing it with the n th+ first sheet detection value.

Abstract: The invention provides a shielding device which may be mounted relative to a roller of a roller applicator for applying liquid to one surface of a pair of intersecting surfaces. The device functions to provide a continuous sharp cut in line at the intersection of the surfaces and includes shielding means, one edge of which forms a contact edge which in use touches the surface to which the liquid is applied and resilient mounting means for securing the shielding means to the roller whereby in use the roller may be pressed against the surface without disturbing the contact of the contact edge with the surface.

Abstract: A solar generator support structure mounting standard photovoltaic panels thereon is disclosed. The solar panels are housed in flat planes (bays and courses) which include a plurality of parallel, symmetrically faceted and stepped areas that are a maximum at the base and over the center of the support structure and which planes define a dome-shaped segment called a hemidome. The planes face upwardly and are stepped, ramped (or a combination thereof) with respect to each other. Single or double axis tracking is provided so that the sun's movement is followed.

The die casting machine further includes an article supporting device, a coating device for coating die lubricant on the first recess and the second recess, a finishing device, a packing device and a recycling device.

Abstract: A switch for adjustably tilting a mirror member of each of a pair of right and left outer mirrors of a motor vehicle in upward, downward, rightward and leftward directions. The switch includes a switch casing, a changeover switch for selecting one of the outer mirrors and an operating switch for adjustably tilting the mirror member of the selected one of the outer mirrors such that a changeover switch knob of the changeover switch is movably tilted in an opening formed at a central portion of an operating switch knob of the operating switch. The operating switch knob is formed with an inner peripheral face and an outer peripheral face such that a lower end of the inner peripheral face is disposed more adjacent to a bottom wall of the switch casing than that of the outer peripheral face.

Abstract: A continuous heat treating furnace in which independent sectioned chambers are provided at least in part of a pre-heating/pre-cooling zone in the furnace body, with a cooler or heater being provided in suction ducts of the sectioned chambers so as to rapidly heat or cool the metallic strip through operation of dampers disposed in the suction ducts, thus making it possible to alter heat curves as required for heat treatment of various metallic strips.

Abstract: A back-mirror angle adjustment assembly, wherein a mirror holder is so held by a spherical bearing as to be freely inclined, the heads of screw rods are connected to each of the two connecting portions which are crossed at right angles with respect to an inclination center at the back face of the mirror holder, and which drives the mirror holder to be inclined by way of pushing and pulling the screw rods, and both the rooms and openings of the connecting rods are formed in a rectangular shape along a radial direction centering the spherical bearing, while the heads of the screw rods in square are inserted within the rooms so as to be maintained unrotatably and at the same time movably in relation to the mirror holder.

Abstract: A heat treating furnace for a metallic strip, which includes a heat exchanging zone and a heating/soaking zone provided within a furnace body by dividing the furnace body with a partition wall disposed in a widthwise direction so as to transport the metallic strip in a confronting state through the heat exchanging zone. The heat exchanging zone is further provided with nozzles for jetting atmospheric gas of the heat exchanging zone onto opposite surfaces of the metallic strip being transported, an atmosphere supply duct for the nozzles, and a circulation fan so as to utilize sensible heat discharged or dissipated from the metallic strip during pre-cooling for pre-heating the metallic strip.

Abstract: An automated and manually-operative carcass-splitting apparatus is disclosed. Enhanced alignment of a centerline of a carcass with a circular blade of a saw assembly is provided. The carcass is suspended by hooks on a continuously moving conveyor system. Indexing permits selective engagement between a station's frame and the moving conveyor. The station simultaneously moves horizontally while it descends in concert with the horizontal movement of the carcass. A hydraulically-driven suspension mechanism pivotably suspends a fluid-powered saw with freedom for several directions of manually-controlled movements during carcass cutting.

Abstract: A gas shielded arc welding torch is described which uses a consumable electrode wire. A cylindrical support member carries a guide tube for guiding the electrode wire through the torch.
