Patent EP-0552040-A1 (EP)
Inventor: LEACH PATRICK ARTHUR
IPC: H04R7/20
Filed: 1993-01-14
Abstract: A method of making a loudspeaker cone and surround assembly comprises clamping at least the outer marginal edge of a cone in a mould having a cavity defining a surround and injecting an elastomeric material into the cavity through an annular orifice extending substantially continuously around the said marginal outer edge to form a surround attached to the outer marginal edge of the cone. 
     Preferably the method comprises the step of feeding the elastomeric material to the annular orifice through an annular feed chamber extending around the mould cavity. The annular orifice may be narrow in width in comparison to the thickness of the surround and the method may comprise the step of separating the surround from an annular ring of sprue formed by elastomer which has solidified in or outside the annular orifice by tearing while the elastomer is still hot from the injection moulding step. 
     From another aspect the invention is injection moulding apparatus for carrying out the method described above.

Abstract: An antiplaque mouth rinse conducive to oral hygiene. The mouth rinse composition includes a water-alcohol vehicle having dissolved therein two antibacterial agents that coact to promote the delivery of these agents and their retention on the teeth and soft tissue in the dental region of the oral cavity of the user, thereby inhibiting the formation of plaque. One agent, Triclosan, is water-insoluble and noncationic, a solubilizer therefor being included in the composition. The other agent, cetyl pyridinium chloride (CPC) is soluble in water and alcohol and is cationic. When the combination of Triclosan and CPC is delivered to the dental region, it is adsorbed and retained thereby to afford enhanced antibacterial activity.

Abstract: A method of detecting the point of origin of a position sensor (10) such as an optical linear scale comprises first displacing an object member (12) whose position is to be determined until it butts against a mechanical stopper (14), then determining the position of the object member at the mechanical stopper and using that position as a reference position for the point of origin, and thereafter detecting the position of the object member (12) by means of the position sensor (10), thereby detecting the position of the object member relative to the point of origin. In another such method, a first point of origin signal may be obtained from an optical linear scale (70) used as a position sensor and stored (30) in response to a latching signal generated at an end point of travel of the object member. Subsequently, when a second point of origin signal from the optical linear scale is compared with the first point of origin signal, any deviation from the first point of origin signal may be corrected based on the result of the comparison.

Abstract: A magneto-pneumatic timing device is disclosed that provides a pressure signal alternating between a high and a low pressure output signal. The duty cycle may be varied as well as the overall cycle time. A magnetically biased flexible diaphragm divides a chamber into a pair of subchambers and the differential pressure between the subchambers is controlled to cause the flexible diaphragm to pull away from the magnetic bias to one position and to return to its biased position. Control of the output pressure signal is carried out by varying the resistance in certain of the pneumatic passages that are part of the control function for the differential pressure. The device is relatively simple and inexpensive to construct and features very few moving parts, thus it is reliable and capable of high production, low cost manufacture.

Abstract: A method for settling a transducer (18) of a hard disc drive (10) on a target track (30) on a rotating disc (12) of the disc drive at the end of a seek to the target track in a determined time period. The time period is divided into two deadbeat intervals (58, 60), each of which is divided into a plurality of time intervals in each of which the location of the transducer with respect to the target track is measured (80) and an accepted value of transducer velocity is measured (82) or determined from successive locations of the transducer. In the first time interval of each deadbeat interval, a deadbeat value of a control signal is determined (88) on the basis of ideal deadbeat settle of the transducer to the target track and outputted to a power amplifier (36) that drives the actuator (40) on which the transducer is mounted for radial movement of the transducer across the disc. In subsequent intervals of each deadbeat interval, an interval correction (102), determined in relation to the difference between a projected velocity determined from the deadbeat value of the control signal and the accepted velocity of the transducer, is added to the deadbeat value and outputted (94) to the power amplifier. A second interval correction (132, 136, 138) can be added to the deadbeat value to correct for a long power amplifier time constant.

Abstract: The invention relates to a process which is characterised by low melting costs and also reduces the environmental load and to a simple-functioning piece of equipment for melting iron alloys, in particular steel scrap, in a coke-fired cupola furnace for the production of cast iron. According to the process, the furnace gas is partially withdrawn at a temperature of > 400 degrees Celsius in the preheating zone and is simultaneously fed in again in the melting and superheating zone with > 23 per cent oxygen. A further characteristic is that the partially withdrawn furnace-gas quantity constitutes up to 70 per cent of the furnace gases resulting in the melting process. Through feeding in furnace gas, in particular through the CO content of the furnace gas, gaseous fuel is fed in which burns with the oxygen. The reducing conditions in the gas-fired cupola furnace are thus intensified, in turn resulting in an improvement of the metallurgical effects. <IMAGE>
