Title: Preemphasis and clipping apparatus for reducing distortions
IPC: H04B1/62
Filed: 1980-03-10
Abstract: Preemphasis (34) and clipping (42) apparatus is provided in a system for translating a signal wave (C11) from an input terminal (30) to another terminal (C44). The preemphasis and clipping circuits are arranged to interact with each other i.e. they are directly interconnected as opposed to being isolated from one another, in a manner which tends to reduce distortions of the translated signal wave. The clipping circuit has components (44, 46) arranged to change a time constant by interacting with time constant elements (38, 40) associated with the preemphasis circuit, during the operation of the clipping action. The interaction also causes the clipping to be maintained beyond the time it would normally fall off. This corrects distortions e.g. arising from overshoots when transients have been preemphasized. <IMAGE>

Title: Dioxolane derivatives
IPC: C07D317/34
Filed: 1981-03-05
Abstract: The invention is concerned with novel dioxolane derivatives of the formula:   <IMAGE> I  in which Ra is hydrogen or (1-4C)alkyl and Rb is (1-4C)alkyl or phenyl optionally bearing a halogeno substituent; their production; and their use for the manufacture of certain known anti-arthritic acids of the formula:   <IMAGE> V  and, in particular, those acids in which Ra=Rb=methyl or Ra=ethyl and Rb=phenyl, by a novel reduction process. The preferred reduction procedures involve the use of an alkali metal borohydride or cyanoborohydride in the presence of a noble metal catalyst, or the use of an  alpha -branched alkyl or cycloalkyl Grignard agent. The use of the derivatives of formula I avoids the need for potentially toxic reagents and reactive intermediates in the previously known processes for the production of the acids of formula V.

Title: Billet heating furnace
Inventor: BRENNAN DANIEL FRANCIS
IPC: F27D19/00
Filed: 1981-07-08
Abstract: A billet heating furnace of the enclosed skid type comprises a feed mechanism (47) for regularly adding to and pushing a row of billets along a skid (31) extending through a furnace chamber (22) which is formed by a lower section (1) and an upper section hinged together. At the outlet end of the furnace chamber the heated billets move onto a delivery path (55, 56, 57) for passage to a press. Along this path there is a billet detector (58 to 63) which responds to any interruption of the regular passage of billets to shutdown the burners are controlled to maintain an operating temperature in the chamber which is higher than the melting temperature of the billets and which heats the billets to a stamping temperature. The furnace chamber (22) is lined with ceramic fibre material (21) having a low thermal mass such that, if the burners (28) are shutdown the temperature in the chamber will fall to below the melting temperature of the billets before the temperature of the billets can rise to the melting temperature. At the same time as the burners are shutdown, a slide (64) in the delivery path (65) is opened so that any billets subsequently leaving the furnace chamber will be directed down a which reject chute (66) until the furnace operator decides that the feed to the press is ready to be recommenced. <IMAGE>
