Title: Heating devices
Inventor: SIMPSON BARRY
IPC: H02H5/04
Filed: 1992-03-26
Abstract: A heating device such as an electric blanket or pad includes a substrate and a heating element (10) that heats the substrate. The heating element (10) has first and second elongate conductors (12, 14) arranged coextensively with one another, at least one of them being a resistive heating conductor, and an insulator (16) that separates the conductors. A half-wave rectifier such as a diode (D1) is connected between an end (22) of the first conductor (12) and an end (24) of the second conductor (14). The first and second conductors (12, 14), input terminals (18, 20) for connection to an AG supply, and the diode (D1) are so interconnected that, during half-cycles of the AC supply of one polarity only, heating current from the supply will flow through a first path comprising the first conductor (12), the diode (D1) and the second conductor (14), with the heating current flowing in opposite directions in the first and second conductors, respectively. A fuse (F) and a thermally actuated circuit interruption device (TF) are connected in the first path. A resistor (R), which is thermally coupled to the thermally actuated circuit interruption device (TF), is connected in series with a second diode (D2) between one (20) of the input terminals (18, 20) and an end (28) of the second conductor (14) such that, in the event of a reduction in the impedance of the insulative means (16), current can flow from the supply during half-cycles of the AC supply of the opposite polarity through a second path comprising the resistor (R), the second diode (D2) and the reduced impedance. The device may also take other forms such as a heated face mask, foot warmer, shawl, duvet or boot. <IMAGE>

Patent GB-2258277-A (GB)
Title: Brush seals
Inventor: HILL PETER WILLIAM
IPC: F16J15/32
Filed: 1992-07-22
Abstract: A multi-stage brush seal is for providing a seal at a shaft surface. The seal comprises a number of brushes spaced apart along the shaft (2), each having bristles (1) mounted (8) in cantilever manner and extending radially toward the shaft surface. In addition to the conventional back support plate (3) disposed downstream of the bristles, each brush includes an upstream shield (10). The shield (10) prevents disturbance of the bristles (1) due to turbulent air flow (13) between adjacent brushes, which otherwise tends to displace them and reduce the quality of the seal at the shaft surface. The shield (10) is spaced from the bristles (1) to form a narrow channel (14). Fluid entering the channel (14) through holes (15) in the shield (10) flows radially (17) over the bristles to maintain them in the optimum position and order. Fluid may be injected externally (20, 21) Fig. 4 (not shown) into the channel (14) for improved control of the radial flow (17). The injected fluid (21) is suitably cooling air to assist in reducing the seal temperature. A plate may be positioned in the channel 14 and biassed against the bristles by a wave spring, Fig. 6 (not shown) to minimise disturbance of the bristles due to the fluid flow. The shield 10 may take the form of a spring plate that also holds the bristles in place, Fig. 5a (not shown). <IMAGE>

Title: Emergency stop apparatus for elevator
Inventor: OKADA RYOJI
IPC: B66B5/18
Filed: 1995-03-14
Abstract: At least one of a molybdenum alloy, tungsten, a cobalt alloy and an iron-nickel-cobalt-chromium alloy in the form of a pin-like friction material (10) is securely fixed to the sliding surface of a brake shoe shoe (5a) used for an emergency stop apparatus employed in an elevator. The above-described materials do not lose their mechanical strength even due to a temperature rise caused by frictional heat, and accordingly, they can maintain a high level of coefficient of friction and that of wear resistance. By the use of one of these materials, it is thus possible to realize a lightweight emergency stop apparatus which is capable of coping with a greater level of braking energy. Alternatively the brake material can comprise inserts of a tube or a bolt (Figs 8 - 10) or an overlayer of material built up by spraying or welding. The latter preferably has grooves in the sliding surface (Figs 11 and 12). <IMAGE>
