Abstract: A synthetic rubber composition is made by heating a mixture comprising (1) a titanium dioxide-filled heat-hardenable organopolysiloxane, (2) benzoyl peroxide or tertiary butyl perbenzoate as a cure accelerator for (1), and (3) less than 0.5 per cent. by weight of the polysiloxane of an organic peroxide, selected from ditertiary butyl diperphthalate, tertiary butyl hydroperoxide, dipersuccinic acid, ditertiary butyl diperadipate, and ditertiary butyl dipersuccinate. The siloxanes used are highly viscous, gummy or elastic solids obtained by treatment of liquid polymers with known catalysts. The titania is used in amount, e.g. of 75 to 225 parts per 100 parts of the siloxane. In coating surfaces such as porcelain enamel, glass, aluminium, steel, copper and polymonochlorotrifluorethylene, a mixture of the siloxane, titania, cure accelerator and the organix peroxide is applied, preferably after ageing at room temperature, to the solid surface and heated, preferably under pressure at 100 DEG to 200 DEG C. The products may be further heated, e.g. at 200 DEG to 250 DEG for 1 to 24 hours. Examples are given, in the third of which aluminium powder is added to the composition containing ditertiary butyl perphthalate. Glass tape, glass fibres, glass-fibre sheets, e.g. glass cloth and electrical conductors may also be coated with the compositions. The compositions may be used for sealing casings (containing electrodes) of electrical discharge devices, and for making seals for pumpless power rectifiers, steam irons &c.

Title: Asynchronous multiplexer and demultiplexer combination
IPC: H04L5/24
Filed: 1976-04-07
Abstract: An asynchronous digital time division multiplexer and demultiplexer combination at one communication terminal is disclosed that will multiplex first N asynchronous source data signals having a first mixture of different bit rates into a transmitted synchronous data stream having a predetermined fixed data format and a given bit rate greater than the total of the bit rates of the source data and to demultiplex second N asynchronous source data signals having a second mixture of different bit rates from a received synchronous data stream having the predetermined fixed data format and the given bit rate. The combination includes an automatic channel assignment circuit to assign channels of the two data streams to the asynchronous source data signals in a manner to minimize temporary data memory regardless of the number of different bit rates by assigning the data signals to channels of the associated one of the two data streams so that the bits of each of the data signals tend to have equal spacing throughout the bits of the associated one of the two data streams. The channel assignment control circuit also includes a means to automatically indicate when the total of the mixture of bit rates has exceeded an allowable maximum.
