Filed: 1978-11-08
Abstract: A valve grinding attachment comprises a flexible hard rubber circular cylindrical boss (14), one end of which ends in a suction cup (13) and from whose other end there projects a stub- shaft (17). The stub-shaft consists of a solid circular steel cylinder which is initially formed separately from the rubber boss and is secured to the boss via an enlarged diameter steel cylinder (16) which is machined integrally with the stub-shaft (17). The stub-shaft is small enough in cross-section, hard enough, and suitably shaped, as to be capable of being gripped repeatedly in a chuck of a hand-held drill. The transition from the rubber boss (14) to the suction cup (13) is accomplished via a reduced diameter section (18) which, in use, allows the stub-shaft (17) to make limited articulating movements relative to the cup (13). <IMAGE>
Patent GB-2037534-A (GB)
Title: Loudspeakers
IPC: H04R1/28
Filed: 1978-11-08
Abstract: The diaphragm of a loudspeaker (Fig. D) feeds ports X, X', port X' being open and port X being closed by an air volume V. If the speaker is in phase with the resonance port X and volume V, it acts as an open port and port X' is ineffective. However, if the resonant amplitude builds up and increases beyond that of the speaker the air motion oscillates along port X', thereby lowering the resonant frequency and producing a phase lag. Other arrangements described require some acoustic energy from a speaker to reach an acoustic mass X and other acoustic energy from the speaker to reach an acoustic mass X'. Masses X, X' may be cylindrical or tapered ports, horns, auxiliary bass radiators, slots or further powered units. An L.E.D. may indicate overload. Infra sound below 20 Hz may be reproduced. <IMAGE>
