Abstract: A backing for an absorptive device such as a disposable diaper or a sanitary napkin, said backing comprising a combination of two layers. The first layer which does not contact the wearer's skin is preferably comprised of a liquid-impervious layer of polymeric film or the like. The second layer is also preferably comprised of a polymeric film which has been made pervious to liquid by providing a multiplicity of relatively small proturberances, each ending in an aperture, substantially across its entire surface. The apertured protuberances, which resemble a tiny volcano in cross-section, exhibit a soft, highly consumer preferred tactile impression which is sometimes characterized as «silky». In backsheets of the present invention, the second layer is oriented so that the tiny volcano-like cusps of the second layer constitute the exposed portion of the backsheet. This minimizes the area of contact between the backsheet and the wearer's skin. In a particularly preferred embodiment of the present invention, the second layer is macroscopically expanded to provide a three-dimensional pattern in its surface, thereby increasing the amount of stand-off between the wearer's skin and the liquid impermeable first layer of the composite backsheet. The tiny apertures in the second layer substantially prevent occlusion of the wearer's skin by providing circulation of air between the first liquid impervious layer of the backsheet and the wearer's skin. This effect is enhanced even further when the first layer is macroscopically expanded to enhance the amount of stand-off between the wearer's skin and the liquid impervious first layer. The reduced contact area and the enhanced air circulation between the backsheet and the wearer's skin reduce the tendency toward perspiration and sticking of the backsheet to the wearer's skin.

Abstract: The machine has a stator with multiple sequentially energisable phase windings and a rotor magnetised to seek a minimum reluctance position with a progressively moving electromagnetic field produced by the phase windings. A switching device in series relative to a D.C. supply with each phase winding is controlled to produce the progressively moving electromagnetic field. A charge storage capacitor associated with each phase winding has one terminal having a low impedance path to the supply. The other terminal has alternative connections to opposite ends of the winding. The first such connection is established by a diode means to that end of the winding connected to the switching device. The diode is oriented to permit passage of forward current continuing in the winding after turn-off to the switching device. The second such connection to the other end of the winding is established by a second controlled switch. A device is provided to turn on the second switching device simultaneously with the first.

Abstract: The switching transistor-in series with the primary winding of a transformer with multiple secondary windings for a TV receiver-is controlled by a starting oscillator and a pulse width modulator. This oscillator is started by rectangular pulses having a large duty cycle and a frequency lower than that of the pulse width modulator. The duty cycle continuously decreases after starting and the operation of the starting oscillator is shut off by the first pulse of the pulse width modulator. After the switching transistor has started to be controlled by the modulator, the duty cycle is reduced further by until the pulses from the modulator have an equal duty cycle value. The starting oscillator is a multivibrator circuit with two transistors. The frequency of the modulator is the line frequency.

Abstract: Gas heaters with atmospheric burners have the NOx content in their waste gases reduced by recycling a certain percentage of the waste gases into the air intake for the burner. The pipe for the waste gases, which is surrounded by a concentric pipe for the air intake from outside the building, has several reflux holes. The amount of the recycled waste gas is determined by restrictions or butterfly valves in either pipe. The atmospheric gas burner (20) at the bottom of the heater (1) receives the primary air (3) for the injector (4) and mixer tube (5) and the secondary air (7) through a channel (6) from the pipe (11a). A fan (8) with a motor (9) passes the waste gases through the box (19) to the concentric pipe (10a). Some of the waste gas is recycled through the reflux holes (12a). The amount is governed by restrictors (14.1,14.2,15), or a butterfly valve (13).S

Abstract: The chair has a seat or seat portion equipped with a balance and its linkage structure has links fixed in articulated manner to a support arm and to which there is articulated a balance device in parallelogram-like manner. A slide is slidingly guided on the balance device and is connected by means of a thrust rod to an extension arm of the backrest-side link. The slide is also connected to one end of a spring element, the other end of which is supported on the balance device. The linkage structure is supported on the backrest by means of a backrest strut articulated to the slide. The seat and backrest portions of the chair frame can be constructed as a plastic shell with a knee-side bending joint and a further bending joint between the seat portion and the backrest portion. Due to the construction of the chair frame to incorporate a balance device, as least part of the forces exerted by the occupant or user of the chair can be absorbed by the balance device, so that the spring element can be made smaller and therefore less expensively, and there is also no need to adjust or adapt the spring element to different body weights of the users of the chair.

Abstract: A leak detection and location method and apparatus for detection of perforations in a obscure geomembrane liner is set forth. In a typical application, upper and lower liners are positioned contiguous to one another and a conducting liquid is placed between them. In the event a tear or perforation is formed in the lower liner, a current flow path is established from a power supply and conductors connected to the power supply. The current flow path extends through the liquid to the leak. Because of the liquid path through the liner, electric current will flow through the perforation and establish an associated magnetic field in the near vicinity of the leak. Magnetic sensors are then swept across the surface of or through the impounded liquid above the liners to indicate such magnetic field variations and the locations of such perturbations correspond to the locations of the leak perforations.
