Title: Improvements relating to integrated circuit substrates
IPC: G11B5/70
Filed: 1970-02-24
Abstract: 1,260,973. Ferrite bodies; circulators and phase-shifters. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 24 Feb., 1970 [27 Feb., 1969], 8858/70. Headings H1H and H1W. A paramagnetic sintered ferrite substrate for an integrated microwave system contains regions of a soft-magnetic sintered ferrite, the two ferrite materials being interconnected by sintering. The paramagnetic ferrite has a Curie point lower than the lowest operating temperature of the system. The substrate, e.g. a thin plate may be made by separately forming the pre-sintered and ground ferrites, mixed with a binder, into foils; punching out areas from the paramagnetic ferrite foil; inserting correspondingly-shaped pieces of soft-magnetic foil and then sintering the composite foil. Alternatively, the ferrites may be separately granulated with a binder; arranged in a matrix in a desired pattern, moulded under pressure and then sintered. Specified ferrites are Mn-Mg ferrites and Y1G (soft-magnetic). Paramagnetic ferrites having the same crystal structure and shrinkage characteristics are obtained by incorporating Al ions into the Mn-Mg ferrite, or Al, or Si and Ca, or Al and Si and Ca ions into the Y1G. A circulator (which forms part of an isolator) (Fig. 3) is made by mounting a paramagnetic ferrite substrate 13, in which has been inserted a softmagnetic ferrite disc 14, on a brass mount 10 provided with connections 11, 12. Circular metallization 15 and metal conductors 16 adjoining reflection-free energy absorber 17, are vapour-deposited, and the soft-magnetic region is premagnetized in a direction perpendicular to the surface of the substrate. The soft-magnetic region forms an x-band-strip conduction circulator with metallization 15. A substrate containing four digital non-reciprocal phase shifters (Fig. 2, not shown) is made by threading wires through holes in soft-ferrite discs inserted into a paramagnetic ferrite plate, the discs being interconnected by vapour-deposited conductors.

Title: Improved process for the synthetic manufacture of ethyl alcohol and ethyl acetate
IPC: C25B3/25
Filed: 1918-05-31
Abstract: 140,115. Pascal, P. V. H. April 3, 1917, [Convention date]. Alcohols, glycols, ethers, hydrocarbons, and oxygen, obtaining.-Aldehyde or paraldehyde, derived from acetylene, is electrolytically reduced to alcohol or ethyl acetate. An acid electrolyte is employed, such as sulphuric acid of 5-10 per cent strength, or a solution of sodium bisulphate, phosphoric acid, or an organic sulphonic acid. If a mercury compound is added, acetylene may be passed directly into the liquid instead of being separately converted into aldehyde. In the production of alcohol, anode oxidation is prevented by a diaphragm, but for ethyl acetate the diaphragm is omitted or an inefficient one employed. The cathode may be of lead, pure or antimoniated, and optionally amalgamated or electro-plated with lead, or a body of mercury may be used. Suitable materials for the anode are platinum, lead, oxide of iron, carbon, and graphite. The last two impart an agreeable bouquet to the alcohol. When alcohol is to be produced, a cathode density of 2-3 amperes per sq. dcm. is employed and the temperature is not allowed to rise much above 40 C. About 10 per cent of aldehyde is initially added to the electrolyte; a subsequent addition may raise the proportion of organic substance above 30 per cent. If the temperature, concentration of acid or aldehyde, current density, or duration of treatment is increased, by-products ara obtained. such as 1-3 butane-diol, crotonyl alcohol, butyl alcohol, and ethyl ether. Catalytic dehydration of the first or second of these gives butadiene. Oxygen, with or without ozone, is evolved at the anode, and may he utilizeed for metal-worlting, purification of waste waters and sewage, or oxidation of nitrous vapours.
