IPC: G10K11/16
Filed: 1983-11-24
Abstract: A speaker 17 is connected by a waveguide 19 to an acoustic mixer 15 leading from a duct 13 carrying source sounds to be cancelled by an active acoustic attenuator 11. The coupling component which couples the physical system with the electronic system 11, consists of a microphone array 33 disposed in the duct 13, and a microphone 35 disposed in acoustic mixer 15 downstream from the waveguide 19. Broad band noise is sensed by microphone array 33 which produces a signal which causes an adaptive filter 23 to drive the speaker 17 so as to introduce "cancelling" noise. The microphone 35 senses the degree of cancellation of the source sound by the speaker 17. The signal from microphone 35 produces an error signal, which is also sent to the adaptive filter to adjust its output so as to produce a more effective "cancelling" sound from the speaker 17. <IMAGE>

Title: Clutch disc with torsional vibration damper
Inventor: WEISSENBERGER HULMUTH
IPC: F16F15/123
Filed: 1984-12-12
Abstract: A clutch disc includes a torsional vibration damper with under-load 2 and idling 3 dampers in which a prefabricated unit consisting of hub and hub disc 23 of the idling damper is provided. Between the output part of the under-load damper 2 and the hub 20 there is provided a toothing 6 18, 19 with play in the circumferential direction. The internally situated cover plate 7 of the under-load damper is made with the appropriate larger toothing 22 so that it can be fitted over the toothing 19 of the hub. After the introduction of this cover plate 7 it is rotated through a specific amount in the circumferential direction and riveted 17. Thus this cover plate 7 can be utilised in relation to the toothing in the hub as axial guide. The other components which must be fitted from the same side are also correspondingly formed. Due to the separate formation of the 16 internally situated cover plate of the under-load damper and of the transmission component of the torque to the idling damper 3 it is possible to achieve a higher operational reliability and simpler fitting, compared with the prior art. <IMAGE>

Patent GB-2171225-A (GB)
Title: A control system for pastry rolling
Inventor: HUDD STEPHEN DENNIS
IPC: A21C3/02
Filed: 1985-02-20
Abstract: Pastry (P) is fed through a series of roller pairs (1a, 2a, 1b, 2b), progressively being squeezed thinner. To keep the loops between roller nips constant, the downstream rollers (1b, 2b) are driven faster than the upstream ones (1a, 2a). Each loop has a height sensor (3a) and deviations from a pre-set height (6a) are determined by a comparator (5a) and used to generate a relative speed change of the rollers between which that loop is suspended to keep the loop constant. The rollers are similarly governed to a pre-set speed, but this is over-ridden on demand from the loops. Thickness gauges (10a, 10b) just downstream of each roller pair have their outputs compared (11a, 11b) with a pre-set thickness (12a, 12b) and deviations from this are used to adjust the nip to keep the thickness constant. <IMAGE>
