Title: Process of making liquid fuel from peat
IPC: C10L1/02
Filed: 1921-09-22
Abstract: A liquid fuel is prepared by the fermentation and distillation of peat, with or without the addition of distillation products of colza oil.  The peat is steeped in water and allowed to stand while a fungoid growth takes place; it is then kiln-dried, crushed, and mashed in a mash-tun.  The liquid extract is then fermented with yeast &c. and distilled.  The distillate may be used by itself or mixed with a product obtained by distilling colza oil at a pressure of eight atmospheres and a temperature of 600 DEG  F.  The colza oil distillate may be replaced by a product obtained from the rape oil plant by steeping in water, distilling in a tar or like still at about six atmospheres, and redistilling at about 200-300 DEG  F.

Title: Improvements in or relating to repeater testing arrangements in electrical signal transmission systems
IPC: H04B17/40
Filed: 1957-08-09
Abstract: 824,508. Unattended repeaters. WESTERN ELECTRIC CO. Inc. Aug. 9, 1957 [Aug. 27, 1956], No. 25191/57. Class 40 (4). A' two-way transmission system has, at the side of an unattended repeater remote from a terminal or other attended station, means selectively to receive two frequencies transmitted from the terminal station and to generate their difference frequency which is returned to the terminal to indicate repeater performance. In the system illustrated in Fig. 1, testing is done at a west terminal which transmits on a high-frequency band while an east terminal transmits on a low-frequency band, transmission being over two wires and each repeater having separate amplifiers for each direction or a single amplifier for both. Each repeater has a fault location network on its east side, as shown in Fig. 2, with parallel connected crystal filters of the hybrid coil type to pass frequencies F1 and F2. These frequencies are mixed by a copper oxide varistor and their difference F3 is passed over a narrow band filter and an attenuator back to the line. The frequency F1 is common to all repeaters while the frequency F2 is characteristic of a particular repeater, both these frequencies lying in the high transmission band while their difference for each repeater lies in the low transmission band. Test signals sent out from oscillators 14 and 15 at the west terminal over the high band therefore cause the return of a signal over the low band which is measured by a resonant wave meter 17. The repeaters may be of a common amplifier type as described in Specification 425,639.

Title: Dehalogenation of organic compounds
Inventor: BENNETT ROYSTON HENRY
IPC: C07C17/23
Filed: 1962-07-03
Abstract: A highly fluorinated olefinic or aromatic compound is made by dehalogenation of a fluorine-containing highly halogenated organic compound in the vapour phase by contact with at least one solid metal fluoride, which is capable of acting as a strong reducing agent, at a temperature in the range 200-700 DEG C. Preferred fluorides are chromous fluoride and ferrous fluoride, but stannous fluoride may be used in some cases.  By this process an aliphatic chlorofluorocarbon or chlorofluorohydrocarbon is dechlorinated to a fluorinated olefin; chlorofluorocyclohexanes, chlorofluorocyclohexenes, and chlorofluorohexadines give chlorofluorocyclohexenes, -hexadienes and -benzenes; high-fluorinated cyclohexenes and -hexadienes containing vinylic hydrogen atoms only give highly-fluorinated benzenes; hexafluorohexadienes give tetrafluorobenzenes; heptafluorocyclohexadienes give pentafluorobenzene; octafluorocyclohexadienes give hexafluorobenzene; a perfluorocycloalkanes containing a six-carbon ring gives a perfluorinated aromatic hydrocarbon; perfluorodecalin gives perfluoronaphthalene; perfluoroethylbenzene gives octafluorostyrene. The process may be combined with a regeneration of the metal fluoride by reduction with hydrogen.
