Patent GB-586799-A (GB)
Title: Improvements in and relating to the production of alcohols
IPC: C07C29/149
Filed: 1944-09-25
Abstract: Alcohols are produced by hydrogenating at elevated temperature and pressure, and in the absence of added catalysts, a mixture containing a lead soap of a carboxylic acid, and a carboxylic acid and/or ester thereof, the lead soap comprising 50-75 per cent of the mixture on a molar basis.  The reactants may be passed in fluid state through a tubular reactor at 200-400 DEG , preferably 300-350 DEG  C., and 5-1000 or more atmospheres, preferably with an excess of hydrogen. With lead soaps of long chain fatty acids such as animal and vegetable oil acids, temperatures may be below the melting point of lead.  Removal of products is facilitated by using a reactor having a high length: crosssection ratio, high rate of hydrogen flow, and the exit lower than the inlet. Carboxylic acids and their salts which may be treated include fatty acids, hydroxy acids such as glycollic, lactic and tartaric, polycarboxylic acids such as oxalic, glutaric and adipic, unsaturated acids such as acrylic, methacrylic and oleic, and aromatic acids such as benzoic and naphthenic acids.  In examples, a sloping steel pressure tube is used for hydrogenating lead laurate and lauric acid in a molar ratio of 2 : 1; lead soap of coconut oil fatty acids and free acids in a molar ratio of 74 : 26; and lead soap of coconut oil fatty acids with free acids and esters in a molar ratio of 65 : 23 : 12, conversion of total acids to alcohols being above 80 per cent.  Specifications 562,609, 562,610, 582,699, 584,939 and 585,219 are referred to.

Abstract: 811,413. Substation circuits. AUTOPHON A.G. June 14, 1957 [June 19, 1956], No. 18863/57. Class 40 (4). In a substation including transistors T1, T2 supplied over the line L, an A.C. bell G 1 in series with a condenser C1, and voltage dividers R2, R3 and R6, R7 for providing the bias for the control electrodes of the transistors, the supply for the voltage dividers and for those of the transistors which do not send their output signal over the line (T1, as shown) is derived from a point between the bell G1 and the condenser C1. The bell and condenser act as a low-pass filter to prevent feedback of the voice current, and the bell also forms, with a resistor R1, a voltage divider feeding the transistor amplifier T1, T2 which is used to amplify the output of the transmitter M. A second bell may be connected to terminals WK which are shortcircuited when cradle contacts GK are closed.

Title: Improvements relating to the production of photographs on paper parchment and the like
IPC: G03C1/496
Filed: 1925-07-24
Abstract: 253,380. Jelley, E. E. July 24, 1925. Sensitized films and papers; developing and fixing. -For sensitizing paper, parchment &c. without any gelatin or other colloidal substance a soluble silver salt, the silver of which is chemically combined with one or more of the three higher halogens, is used in conjunction with a water soluble, non-volatile, crystallisable, weak acid. Silver chlorate, perchlorate, bromate, dichlorobenzoate and other salts are instanced, and for the acid citric, tartaric and 2.3.6 trichlorobenzoic acid. The acid solution may be applied to the surface separately, and an alcoholic solution used. Development is effected by organic reducing agents such as metol, pyro, hydroquinone, but amidol is not suitable. If the coating does not contain sufficient silver salt to give the necessary image density (e.g. less than .0005 grms per sq. cm.) the exposure is shortened, and a soluble silver salt (e.g. nitrate, chlorate, but not permanganate or nitrite which destroy the developer), is added to the developer, the hydrogen-ion concentration of which should be between .0001 and .01. A fixing bath of hypo and bicarbonate is specified, but an acid fixing bath may be used. Various tones may be obtained by varying the exposure and the treatment. Detailed particulars of methods of preparing the paper and using it are given. Clean developing dishes are essential, and dishes of vulcanite porcelain or papier machÚ should be coated with paraffin wax.

An apparatus for electroplating articles comprises a barrel 1 suspended from a shaft 3 mounted on a frame 2a, and a vat 10 having a chain drive 13 which is adapted to engage sprockets 4 on the shaft 3. The barrel 1, which is perforated, is suspended by rubber belts 6 from pulleys 5 on the shaft 3, the belts 6 engaging pulleys 7 fixed to each end of the barrel 1. A barrel 1 is moved without rotation through the vat 10, which contains electrolyte and an anode 10a, by the chain 13 until the shaft 3 engages a stop 16 pivoted at 17 on the vat 10, an arm 18 controlled by a solenoid 19 preventing pivoting of the stop 16. The movement of the chain 13 then rotates the sprockets 4, and thus the shaft 3 and barrel 1, until the solenoid 19 is manually or automatically operated, e.g. by time switches, to withdraw the arm 18 and permit the barrel 1 to proceed through the vat 10 to the next stop 16. Cathodic connection to the articles in the barrel 1 is from bus bars 12 on ledges 11 at each side of the vat 10 which are contacted by the chain 13, the current being led by the sprockets 4, shaft 3, frame 2a to cathodes which enter an axial hole at each end of the barrel 1, the holes being wide enough to permit movement of the barrel relative to the frame 2a. A succession of barrels 1 may be passed through the vat 10, an endless chain 20 driven by an electric motor 28 being located at each end of the vat 10 to lift barrels 1 into and out of the vat by means of cradles 24 which are pivoted on the links of the chains 20 and which engage the ends of the shafts 3. Specification 847,074 is referred to.
