Patent GB-2134745-A (GB)
Title: Electro-acoustic transducer
Inventor: TAYLOR FRANK
IPC: H04R1/22
Filed: 1983-02-04
Abstract: In electro-acoustic transducers, especially for use in a telephone subscriber's instrument, to reduce the low frequency response of the transducer without increasing distortion one or more holes or tunnels (11) are provided through the diaphragm support member (5), the holes or tunnels coupling the air behind the diaphragm with the air in front. Such holes or tunnels can also be formed by a groove or grooves in the support member, the diaphragm rim then acting in effect as a lid for the or each such groove. The holes or tunnels do not have to be parallel to the plane of the diaphragm, and the idea is applicable to types of transducers other than the moving coil type. <IMAGE>

Title: Wheels for domestic appliances
Inventor: HARGREAVES ROBERT EDWARD
IPC: B60B33/00
Filed: 1983-05-05
Abstract: A wheel, especially for a washing machine, comprises an inner disc 4 of a resilient material, such as rubber, sandwiched between two outer discs 1,2 of harder more rigid material, such as nylon, and of smaller diameter than the inner disc. The inner disc 4 has on each side a plurality of angularly spaced ribs 5 each extending to the peripheral region of the disc, the inner parts of the ribs being accommodated in co- operating slots 3 in the two outer discs. The projecting part of the inner disc, with the outer ends of the ribs, forms a resilient tread which between adjoining ribs is more readily compressed than at the ribs themselves, this tending to resist "walking", but at the same time the outer discs impart a degree of stiffness which assists in suppressing vibrations. <IMAGE>

Title: Gas turbine engine fuel control systems
Inventor: FITZMAURICE IAN PATRICK
IPC: F02C9/28
Filed: 1983-05-11
Abstract: A gas turbine engine fuel control system includes a transducer N which provides a signal representing engine speed. An @ schedule signal generator (15) receives the N signal and generates an acceleration limit signal which is used during acceleration as a limiting signal. To overcome problems of droop inherent, in such systems a correction signal generated by a function generator (16) is added to the output of the @ schedule signal generator (15). The correction signal is at least in part dependent on the rate or change of the limit signal. <IMAGE>

Title: Fume seal for an electric arc furnace and method of using the same
Inventor: WIDMER COLIN FREDERICK
IPC: H05B7/12
Filed: 1983-12-02
Abstract: A fume seal for an electric arc furnace includes a bed (10), supporting a ring (14) of refractory material with a central aperture (16) to receive the electrode E with clearance. The inner wall (22) of a volute chamber (26) defines with the electrode E the outer and inner sides of an annular chamber, the roof of which is formed by a series of refractory tiles (38). The tiles, when no gas is flowing through the volute chamber, rest on concentric walls (30, 32). When gas is passed into the volute chamber, it passes into the annular chamber through slots (36) and causes the tiles to float independently in the gas flow; as the tiles are independent of each other, any damaged tile can be readily replaced. <IMAGE>

Title: Magnetic field coil for NMR-CT
Inventor: YAMADA TADATOSHI
IPC: G01R33/20
Filed: 1984-12-12
Abstract: A magnetic field generating coil structure for use in a nuclear magnetic resonance computer tomograph in which the boundaries of a slice are precisely determined due to elimination of magnetic coupling between an RF coil and a gradient field coil. The gradient field coil includes coils 1, 2 and 3 for generating magnetic fields with gradients in X, Y and Z orthogonal directions while a uniform field generating structure produces a uniform field in the Z direction. An RF coil structure is disposed within the uniform field generating coil structure and the gradient field generating coil structure. In accordance with the invention, a cylindrical shielding layer (7) made of an electrically conductive material is disposed on at least one of the inside and outside of the gradient field generating coil structure. The thickness of the shielding layer is made equal to or larger than a skin depth determined by the fequency of the RF field and the resistivity of the shielding layer and made smaller than a skin depth determined by the gradient field control frequency and the resistivity of the shielding layer. <IMAGE>

Patent GB-2152908-A (GB)
Title: Bursting machine
Inventor: IRVINE ROBERT
IPC: B65H35/10
Filed: 1985-01-09
Abstract: A bursting machine 10 is provided for separating discrete sheets 19 from a continuous strip of sheets 14 having uniformly spaced perforation lines 22 across the width of the strip, eg. computer printouts. A gauging device 26 with numerical increments in the form of a linear scale is manually compared to the length of the discrete sheets to provide a predetermined number corresponding to a pulse count for entering into a control device 68 through a manually settable device 40. The control device in turn is operatively connected to an electronic pulse counter. When the leading edge 72 of the strip has advanced a predetermined increment after passing a sensing device 70 located downstream in the path of travel with respect to a first pair of continuously driven feed rollers 44, a pulse generator attached to the driven first feed roller 50 is actuated to generate pulses for counting to reach the preset number in the pulse counter. When the preset number is reached, a second pair of intermittently driven feed rollers 60 is stopped through disablement of an electromagnetic clutch 50 and enablement of a brake 64 while the leading sheet is continued to be conveyed downstream by the first pair of feed rollers 44 to effect a burst. <IMAGE>

Filed: 1986-03-25
Abstract: A catch assembly for headgates includes gates 20 that can be opened inwardly or outwardly and trapped in an intermediate position between inner (52) and outer (62) latch means. There may be inner and outer latch plates 52,62, each of which is displaceable by gates 20 moving from the corresponding side so that they can pass. Gates moving outwardly cannot pass the outer plate 62 unless this is manually displaced, because it is not (or not sufficiently) displaced automatically. Gates moving inwardly can pass both plates, e.g. because the outer plate 62 carries the inner plate 52 with it. <IMAGE>

Title: Designs on glass
Inventor: EASTON LESLIE RALPH
IPC: B44C1/175
Filed: 1986-11-19
Abstract: A method of producing coloured designs on glass comprises first printing the design 10 on a sheet of gummed paper (3) to form a water-slide transfer and coating the design with a layer 15 of stoving enamel varnish. The design is removed from the gummed paper by soaking and then applied to a sheet of glass 12. The sheet of glass 12 is then laminated with a second sheet of glass 14 and an interlayer 16, which may be in liquid form, to form a glass laminate. The design is arranged to be on the inner side of the glass 12 so as to be protected from scratching. In use the glass is placed so that the interlayer lies between the design and the main source of light so that the interlayer absorbs ultra-violet light before it reaches the design. <IMAGE>
