Abstract: 1,027,719. Heat-transfer devices. UNITED STATES ATOMIC ENERGY COMMISSION. Nov. 25, 1964 [Dec. 2, 1963], No. 47900/64. Headings F4S and F4U. A heat-transfer device operating in the manner of a Perkins tube comprises a sealed container in which vapour flows by virtue of the vapour pressure gradient between a region of high temperature 1 and a region of lower temperature 2 where the vapour condenses, the condensate being re-circulated to the high temperature region along a capillary path of glass frit or wire mesh 3. Various combinations of heat transfer fluid and container material suggested are water and heat-resistant glass; lithium and a niobium zirconium alloy; silver and tantalum; sodium and stainless steel. The container may be heated at one end and the vapour condensed at the other or alternatively the container may be heated somewhere along its length and the vapour condensed at both ends.

Abstract: A safety device with an inflatable cushion for moving vehicles, particularly automobiles, comprises at least one inflatable cushion, means for expanding and re-expanding the said cushion and a collision detector controlling the actuation of such a device, the cushion being equipped with means for transferring gas in both directions, at two different flow rates, between the surrounding atomosphere and the inside of the cushion, the gas exchange taking place at a low flow rate in the direction from the inside of the cushion to the surrounding atmosphere, for the purpose of deadening the person to be protected when the latter is thrown against the said cushion during an accident, and at a higher flow rate in the direction from the surrounding atmosphere to the inside of the cushion for the purpose of rapidly re-inflating the said cushion as soon as the latter is no longer acted upon by the person to be protected. The device is particularly effective in case of a series of impacts, because it is partially reversible and dissipates a part of the energy by absorbing gas and absorbing the rest of the energy to restore the device to its initial state before a new deadening of the person to be protected.

Abstract: 1469872 Pulse-code-modulation terminals NORTHERN TELECOM Ltd 28 June 1974 [29 June 1973] 28850/74 Heading H3H In a terminal for one channel in a pulse-codemodulation transmission system for transmitting a pulse train of recurrent frames divided into a plurality of channels, the clock pulses required for analogue-to-digital and/or digital-toanalogue conversion at the terminal are derived from the frame and digit synchronization pulses from the incoming digital signals. A counter 32 counts the recovered clock pulses and is reset to zero at the beginning of each frame. If there are more quantizing steps than total number of digits per frame a frequency multiplier could be driven by the recovered clock pulses or two or more coders could be provided operating in succession on a single channel. Analogue-to-digital conversion.-The analogue signal 70 is sampled by capacitor 73 the voltage on which then decays exponentially and is compared at 82 with an exponentially increasing voltage on capacitor 76 of polarity determined by detector 83 which also controls the polarity bit of the digital output signal. The count in counter 32 is transferred to register 86 when the comparator 82 switches over. The polarity bit is added at 87 and the digital output signal is gated out on the channel selected at 33 via AND gate 88 and OR gate 16. Digital-to-analogue conversion.-The incoming digital signal is converted to parallel form at 40 and a capacitor 51 charged to a positive or negative voltage in dependence on the polarity bit. The charge then decays exponentially during the time taken for the output of counter 32 to equal the amplitude bits, held at 43. Switch 57 is then opened and the output of amplifier 50 gated out through audio filter 58.

Title: Middle distillates and low-sulphur residual fuel prodn. - from high-sulphur residua, by distn., thermal cracking and hydrodesulphurisation
IPC: C10G69/06
Filed: 1974-07-29
Abstract: A middle distillate and a residual fuel oil with a low S content are produced by (a) distilling a high-sulphur atmospheric residue under reduced pressure; (b) thermally cracking the distillate; (c) distilling the cracked prod. at atmospheric pressure to form one or more light fractions, a middle distillate and a residue; and (d) catalytically hydrodesulphurising the residue from (a) before or after mixing with the residue from (b) to form a residual fuel oil. The vacuum distn. stage (a) allows thermal cracking to be carried out on the distillate alone, so that optimum middle distillate yields can be obtd. and the loss of storage stability associated with the thermal cracking of residue is avoided.

Title: Residue from decarboxylative oxidn. of benzene monocarboxylic acids - is hydrogenated to give useful prods. such as cyclohexanone or cyclohexanol
IPC: C07C37/56
Filed: 1976-02-28
Abstract: In a process for the decarboxylative oxidn. of a benzene monocarboxylic acid (or a salt, ester or anhydride of this) in the liq. phase at elevated temp. with an O2-contg. gas, the tarry prod. formed is subjected to a hydrogenation treatment. Pref. the hydrogenation is carried out at 400-1200 degrees C (200-500 degrees C) in presence of a hydrogenation catalyst e.g. contg. 10-20wt.% NiO, 50-90wt.% MoO3 and 5-10wt.% CoO. The process is esp. useful for treating the tarry residues obtd. after the oxidative decarboxylation of benzene monocarboxylic acids (benzoic acids (benzoic acid, toluic acid, nitrobenzoic acids, etc) into the corresponding phenols. After recovery if the phenols, a tarry deposit remains which usually contains residues of Cu catalysts used to make the original carboxylic acid. Previously, these tarry deposits have been burnt, but this causes loss of prod. and pollution of the atmosphere with CuO. In the present process, these deposits are now converted into useful prods. Thus hydrogenation of the tarry deposit resulting from the oxidn. of benzoic acid into phenol gives a mixt. of cyclohexanone and/or cyclohexanol which can be recovered and purified.
Patent NL-7606761-A (NL)
IPC: E05D11/00
Filed: 1976-06-22
Abstract: Many motor bonnets of front motor vehicles produce danger in case of frontal collision, because the bonnet then is pressed like a razor into the passenger compartment of the vehicle. Other bonnets cannot readily be opened because the edge of the cover to be gripped, is not reasonably accessible. This danger and disadvantage are overcome by using hinge members having two points of rotation, especially swan necks, and by using rectilinear recesses accommodating rolls in such a way that the bonnet can easily be manipulated but nevertheless is very safe in case of a frontal collision. For further protection of the user against the bonnet being blown shut, a special spring bias fixing rod element is incorporated into the bonnet.
