Title: Tyre treads
IPC: B60C5/00
Filed: 1981-03-09
Abstract: A limited-life temporary spare tyre 10 has a tread 16 designed to generate two-tone road noise as a warning of the need for its early replacement, half the circumference of the tread 16 having a regular, long- pitch, pattern to produce a low tone, and the other half having a regular, short-pitch, pattern to produce a high tone. The long pitch length may be twice the short, and the land/sea ratio of the tread preferably varies sinusoidally from one circumferential end of a tread pattern pitch to the other end. The tread may alternatively be divided into more than two segments, but with each segment extending continuously over at least one-sixth of the circumference. Thus there may be 4 or 6 segments such that segments of the long pitch alternate with those of the short, and there could be segments of a third, different, pitch. The tread may also be used for replaceable bead, retread or solid tyres. <IMAGE>

Title: Improvements relating to blowdown tanks
Inventor: APPLEGATE GEORGE
IPC: F22B37/54
Filed: 1981-07-25
Abstract: A blowdown tank has a top vent (3) to atmosphere for vapour from the blowdown water. It is shielded from the inlet as a safety measure. In one version, the tank is divided into upper (8) and lower (9) chambers by a baffle plate (5), and the inlet (10) is to the lower chamber. Vapour escapes through an aperture (6) in the plate to the upper chamber and thence to the vent. Alternatively, the vent is shielded by concentric walls forming a serpentine path for the vapour. One of these may be part of an open-ended tube extending almost to the bottom of the tank with a branch providing an outlet for the blowdown water. <IMAGE>

Title: Detecting harmonically-rich acoustic sources
Inventor: WILLAN PAUL RICHARD
IPC: G10K11/34
Filed: 1981-07-28
Abstract: A directional detector of a harmonically-rich acoustic source (e.g. a helicopter) comprises an array 11, 12 of microphones, preferably a two or three transducer array such as a Time- Average-Product Array, whose output signals are subjected (18) to 'cepstrum' analysis. This is a process in which the time domain array signals are transformed by Fourier analysis into the frequency domain and then the frequency spectrum is itself Fourier analysed, transforming the spectrum into the so-called "quefrency' domain in which the frequency related harmonic components of the original signal are additive and form one or more peaks characteristic of the identity of the source irrespective of the original signal being hidden by random background noise. Detection preferably includes source identification by comparison of 'cepstral' peaks with reference peaks of known sources. The array preferably includes means to steer the beam between different directions at which measurements are made. <IMAGE>

Title: Cleaning device for the intermediate image carrier of an electrophoretic printer
IPC: G03G15/10
Filed: 1982-03-17
Abstract: To improve the quality of electrophoretically printed colour images, surplus toner suspensions of different colour used are removed from the intermediate image carrier and are conducted to separate collecting reservoirs. To this end, a straight upper edge (5), of an air duct (21) forms a narrow gap in conjuction with the intermediate image carrier (1). Through this gap air is forced to direct the surplus toner suspension from the intermediate image carrier to a collecting reservoir (8) via a wiper (6) and a chute (7). A separate chute and a separate reservoir are provided for each toner suspension, and the chutes can be selectively positioned so that the upper end of a selected chute is located underneath the wiper and its lower end is located over an associated reservoir. <IMAGE>

Title: Planetary reduction gearing provided with a torque limiter
Inventor: TAKEDA SHINICHI
IPC: F16D7/10
Filed: 1982-06-15
Abstract: A machine such as an agricultural cultivator is provided with planetary reduction gearing (8) in the transmission between the engine crank shaft (10) and cultivator rotors (6). In order to prevent damage to the transmission due to sudden or shock overloads applied to the rotors, the gearing (8) incorporates a torque limiter. During normal drive of the rotors (6), the ring gear (11) of the gearing (8) is locked against rotation by a lock-release mechanism (23) including spring- pressed balls (13) engaged in recesses (12) in the ring gear (11). When the rotors, and therefore the ring gear (11), are subjected to excessive rotational forces, the increased turning moment exerted by the ring gear forces the balls (13) out of the recesses (12), and the ring gear rotates until the overload is removed. <IMAGE>
Patent GB-2122290-A (GB)
Title: Self adjusting mechanisms for brakes
Inventor: BASS RICHARD ARNOLD
IPC: F16D55/228
Filed: 1982-06-17
Abstract: A hydraulic brake self adjuster mechanism to limit the return movement of a hydraulic piston (15) includes a fixed length strut (22), a sleeve (24) having a limited axial sliding movement on the strut, and a ball and ramp mechanism acting between the sleeve and the hydraulic piston (15). The ball and ramp mechanism includes an array of caged balls (29) and co-operating surfaces (27,30) on the sleeve and piston which surfaces are convergent in the direction of return movement of the piston. When the brake is applied and if clearance 'C' exceeds the limited axial play of sleeve (24) on strut (22), which play is set by a pin (34) projecting through elongated holes (36) in strut (22), then the piston (15) will move axially relative to the sleeve (24) but on brake release the balls (29) jam relative movement between piston (15) and sleeve (24). To de-adjust, a lever (37) is rotated so that a cam (38) pushes a bar (33) which carries pin (34). As shown, brake is a disc brake operable hydraulically or mechanically: it may be drum brake. <IMAGE>

Title: Manufacture of aluminium nitride
Inventor: DRYBURGH PETER MCALLISTER
IPC: B01J10/00
Filed: 1982-10-06
Abstract: High purity aluminium nitride is manufactured by levitating a charge of molten aluminium (112) in a reaction zone (100) by means of electromagnetic induction in a levitation coil (111) in an oxygen-free atmosphere, reacting the levitated molten aluminium with nitrogen gas at a temperature effective to form aluminium nitride, e.g. 1800 to 2300 DEG C, and recovering the resulting aluminium nitride in an oxygen-free atmosphere. The size of the levitated charge can be monitored and the charge replenished under the control of the monitor. The aluminium to be melted can be stripped of its Al2O3 film by heating to cause Al2O3 to react with Al to form Al2O which is volatile and removed by evacuation. <IMAGE>
