Abstract: 261,042. Radiofrequenz Ges., (Assignees of Giebe, E., and Schiebe, A.). Nov. 7, 1925, [Convention date]. Addition to 252,170, [Class 40 (v), Wireless signalling &c.]. Non-contact-making relays.-The parent Specification describes a device comprising a rod of rock-crystal lying on a metal electrode, a second electrode being arranged above the crystal at a small distance from it, and the whole being enclosed in a more or less marefied space. When the electrodes are fed with current of a frequency equal to the natural frequency of the rod for longitudinal vibrations, a luminous discharge takes place at the point of maximum deformation of the crystal. According to the present invention, the discharge is used as a conducting path for a local source of current connected to a pair of auxiliary electrodes arranged in the path of the discharge, and the device thus acts as a tuned relay for calling or distant control in wireless or wired wireless systems. The luminous discharge may be maintained by the local source when it has once been started, or may cease with the incoming currents.

Title: Improvements in or relating to the production of animal feeds and fertilizers
IPC: A23K1/00
Filed: 1952-11-07
Abstract: Feeds and fertilizers are made by subjecting to fermentation by means of a culture of a micro-organism an aqueous preparation of a viscous substance produced by the growth in mineral-containing water of vegetable organisms, e.g. gum-producing algae, and a suitable carbohydrate, e.g. a cereal flour or offal, to allow proliferation of the micro-organism, and then allowing or causing the product to dry without killing the micro-organisms.  The procedure may include allowing the fermented product to react with chlorophyll-containing vegetable material before the drying. According to an example of animal feed production, a gelatinous preparation is made by allowing pulverized Chondrus crispus to stand in natural water for 6 hours at 25 DEG C., an aqueous preparation of Saccharomyces cereviseal and sucrose is added, ground barley, straw dust or a cereal mill tailing is mixed in, fermentation is allowed to take place, a layer of the dough so formed is covered with a layer of ground green lucerne, and the exothermic fermentation which ensues is allowed to assist in evaporation of the water present.  According to an example of fertilizer production, a dough prepared in the manner just described is brought to pH not less than 5 by adding hydrochloric or sulphuric acid, dried at a temperature less than 40 DEG C., pulverized, and mixed with moss, an alga or like maritime or land organism in dry, pulverized condition and with dehydrated calcium chloride, other fertilizing substances being incorporated also at this stage, if desired.

An internal combustion engine operating with incomplete combustion for instance for the production of synthesis gas simultaneously with mechanical power output is first started with a fuel-air mixture as ordinarily used in the normal operation of diesel or gas engines and is switched over to synthesis gas production when conditions are favourable. Thus the engine can be started with a normal methane air mixture and then switched over to a methaneoxygen mixture for gas production. In an installation consisting of a plurality of separate engine units one or more of the units may be run as a normal internal combustion engine that is for the production of mechanical energy means being provided to switch it over during running. The exhaust may pass to the atmosphere directly or after passing through an exhaust heat utilizing device.

Title: Preparation of cyclic alkanols
IPC: C07C29/145
Filed: 1964-07-10
Abstract: Cylic alkanols are prepared by oxiding cycloparaffins with air in the presence of a boric acid compound to convert at the most, 20 weight per cent to oxidation products including borate esters, vacuum flashing to remove the unoxidized hydrocarbons and ketones, and hydrolysing the residual borate esters to the cyclic alkanols.  The overheads from the vacuum flash are condensed, hydrogenated to reduce the ketones to cyclic alkanols and recycled to the air oxidation step, in a ratio of from about 10 to 25 parts per part of fresh feed. The cyclo-paraffin feed may be obtained by catalytic hydrogenation of cyclic dimers and trimers of conjugated di-olefines, and an example describes the preparation of cyclodecanol from cyclododecane prepared in turn by hydrogenating cyclododecatriene in the presence of a nickel catalyst.  The cyclic alcohols may be further oxidized with nitric acid to the dibasic acids.  Apparatus comprising a hydrogenation reactor, followed by an air oxidation reactor, a condenser, a borate ester flash drum and a reactor in which the borate ester products are hydrolysed is described and illustrated.
