Title: Cupboard drawer gear segment movement - moves closure flap by tooth engagement from closed position to horizontal
IPC: A47B88/00
Filed: 1978-09-14
Abstract: The case or cupboard has a withdrawable drawer, and along its upper edge is a rotatable closure flap. When the drawer is withdrawn, the flap is caused to move from its vertical closed position to the horizontal.

Title: Cable with impact resistant coating
Inventor: BELLI LUCA BALCONI SERGIO
IPC: H01B7/00
Filed: 1999-11-09
Abstract: The present invention relates to a coating for cables which is capable of protecting the cable against accidental impacts. By inserting into the structure of a power transmissioncable a suitable coating of expanded polymer material of adequate thickness, preferably in contact with the sheath of outer polymer coating, it is possible to obtain a cable which has a high impact strength. The Applicant has moreover observed that an expanded polymer material used as a coating for cables makes it possible to obtain a higher impact strength for this cable than using a similar coating based on the same polymer which is not expanded. A cable with a coating of this type has various advantages over a conventional cable with metal armor, such as, for example, easier processing, a reduction in the weight and dimensions of the finished cable and a lower environmental impact as regards recycling of the cable once its working cycle is over.

Filed: 1989-11-09
Abstract: The present invention relates to a novel method for forming metal matrix composite bodies and the novel products produced therefrom. A negative shape or cavity, which is complementary to the desired metal matrix composite body to be produced, is first formed. The formed cavity is thereafter filled with a permeable mass of filler material (7). Molten matrix metal (8) is then induced to spontaneously infiltrate the filled cavity. Particularly, an infiltration enhancer and/or an infiltration enhancer precursor and/or an infiltrating atmosphere are also in communication with the filler material (7), at least at some point during the process, which permits the matrix metal (8) when made molten, to spontaneously infiltrate the permeable mass of filler material (7), which at some point during the processing, may become self-supporting. In a preferred embodiment, cavities can be produced by a process which is similar to the so-called lost-wax process.

Patent PT-92982-A (PT)
Inventor: BARNER NIGEL EVERARD
IPC: H04W72/08
Filed: 1990-01-26
Abstract: A communication procedure suitable for a cordless telephone system involves time division duplex radio communication between a handset 11 and a base station 3 using alternating bursts of transmission over a single radio channel. Once a radio link has been set up, initial transmissions carry a synchronisation logical channel S and a signalling logical channel D multiplexed together, but the link may switch to bursts carrying a communications logical channel B for the speech data and the signalling logical channel D. Burst synchronisation is achieved by the asynchronous detection of words in a synchronisation channel S. These words have bit patterns reducing the probability of incorrect asynchronous detection of them.   If one part ceases to receive handset signals from the other, it transmits a special signal, informing the other part. This enables both parts to detect the failure of a link at substantially the same time, so that their actions to re-establish the link are synchronised.
