Patent GB-2020409-A (GB)
Title: Self-inflating devices
IPC: A43B13/20
Filed: 1979-04-12
Abstract: Self inflating devices are described which achieve a long lasting inflation and, therefore, a useful life. An elastomeric enclosure is initially inflated to a desired pressure by a gas such as hexafluoroethane having large molecules incapable of diffusing outwardly through the elastomeric material except at a relatively slow rate. When the enclosure is surrounded by ambient air at atmospheric pressure, such air passes into the enclosure by reverse diffusion through the elastomeric material, thus extracting energy from the ambient air to progressively increase the total pressure in the enclosure to a substantial extent. This added energy may simply maintain the inflation pressure or it may be used to perform useful work. Thus, an elastomeric bellows device (30) partially inflated with 100% supergas and supporting a weight W on platform (32) self inflates from H1 to H2 when exposed to air at ambient pressure to raise the weight. Embodiments include an insole, a midsole, shock absorbing devices and building structures. <IMAGE>

Patent GB-2066967-A (GB)
Title: Partial discharge detection in the presence of interference
IPC: G01R19/145
Filed: 1979-12-14
Abstract: Partial discharge in a test component (CX) is detected by arranging the test component (CX) in series with a reference impedance (ZSB) across a source of high a.c. voltage (S). A second reference impedance (ZSA) and reference capacitance (CB) can also be connected in series across the source (S). A detector monitors transient pulses across the reference impedance or impedances to identify partial discharges. To enable partial discharges in test component (CX) to be detected in the presence of interference signal (RF1) a second signal (RF2) is injected into the detection circuit whose frequency is of the same order as the interference signal and which is not phase-locked to the interference signal. The two signals combine algebraically to produce a net resulting voltage whose magnitude is, at certain times, sufficiently small to allow a discharge pulse to be detected. The second signal can be injected either in the high voltage or preferably the low voltage side of the detection circuit. <IMAGE>

Patent GB-2077774-A (GB)
Title: Washing Machine
IPC: D06F34/08
Filed: 1980-06-04
Abstract: An automatic washing machine of the fresh-water, vertical-axis type has a dynamic system which includes a single perforate wash basket 32 arranged to be driven continuously such that its central axis moves in an orbital path about another axis, rotation of the basket 32 about its central axis being restrained. Water is introduced into the basket 32, through a hollow annular fill ring 132 on the tub 36 and through a spout 30 to wash detergent from a cup 48, during orbital motion and that motion is effective to induce a continuous motion of the fabric article load for washing the load. Following washing, preferably the basket's central axis is aligned with the axis about which it was orbiting and is rotated about this axis to centrifugally remove water from the fabric load. The basket may be contoured to enhance toroidal and annular movement of the fabric load, e.g. by the provision of curved vanes 39, rings 53, ribs 58 and vanes 60. The machine transmission has an input shaft 203 driven by a reversible electric motor 20, and an output shaft 78 connected to the basket, the transmission having drive elements 74 for interconnecting the output shaft and the input shaft. The drive elements include eccentric drive members operative to shift the axis of the output shaft laterally from the axis of the input shaft when the input shaft is rotated in one direction, thereby driving the output shaft in an orbital path about the axis of the input shaft, and operative to substantially align the axes of the input and output shafts when the input shaft is rotated in the other direction, thereby rotating the output shaft. A one-way clutch and a disc brake assembly, including an off- center coupling, cooperate with the drive elements to restrain the basket from rotating when in the orbit mode or when the motor is deenergized, and to rotationally drive the basket when in the water extraction mode. <IMAGE>
