Title: Improvements in, or relating to, foot-operated pumps for compressing air or other gases
IPC: F04B33/00
Filed: 1924-06-20
Abstract: 241,603. Routledge, W. June 20, 1924. Oscillating cylinder pumps; actuating pumps by foot power.-A foot pump in which the piston is operated by a lever and a crank swung from the same centre, a connecting rod not being used between the crank and piston, is provided with a spring for effecting the return stroke with means for releasing and resetting the spring, so that when not in use it is not subject to strain. The pump has an open-ended oscillating cylinder pivoted to a base at the point c and provided with an air outlet and non-return valve, d. A rod g threaded at both ends connects the piston e to a support f bearing on the cylinder, the distance of the support from the cylinder being adjustable by a nut h on the support. A portion i of the cylinder is cut away to allow access to the nut. The piston and support are pivotally connected by a double eye m to one arm of a crank lever; the other arm j<11> constitutes a pedal formed by elbowed side arms, which moves through equal angles above and below the pivot k. The return stroke is effected by a spiral spring n, one end of which is fixed to the lever while the other is attached to an arm r freely pivoted on the pivot k of the lever and having a catch or recess s at its free end, adapted to engage a catch t on a weighted crank lever v. When the pedal is raised to its highest point the catches engage, and the spring becomes virtually anchored to the frame; the spring is released by tilting the lever v. Alternatively, the lever v may be pivoted to the arm r and provided with a catch to engage the base. The release and setting of the springs may also be effected by catches made to engage by hand. The length of the cylinder and the position of the pedal lever are such that by removing the gudgeon pin from the double eye, the cylinder can be swung into upright position and the piston withdrawn. A handle may be attached to the treadle.

Title: An x-ray tube
IPC: H01J35/10
Filed: 1955-05-24
Abstract: 803,165. X-ray tubes. MAX-PLANCKGESELLSCHAFT ZUR FORDERUNG DER WISSENSCHAFTEN e.V. May 24, 1955 [May 24, 1954; May 4, 1955, (2)], No. 14928/55. Class 39(1). A hollow anode which forms part of the envelope of an X-ray tube and which is itself pervious to X-rays can rotate with respect to the remainder of the envelope, the two envelope parts being connected by a gas-tight joint. In Fig. 4 the anode is in the form of a diaphragm 13 secured to a part-spherical section 11. This rotates in a packing collar 6 inside the main part of the envelope carrying the cathode 4. As shown, an outer casing may be provided through which a cooling liquid is circulated, as at 16, vacuum pump oils having a suitably low vapour pressure. The diaphragm may be supported at its centre against atmospheric pressure. Fig. 5 shows the same arrangement in more detail. The anode diaphragm is demountably secured to the end of the anode support structure 121, 122, itself composed of demountable sections, by an arrangement of clamping and sealing rings, Fig. 6 (not shown). The anode support cylinder 111 revolves in bearings 201, 202 in the main casing structure 214. This is joined to the upper casing by a part 74, which connects to a pump through a socket 73. The vacuum is maintained by packing joints 61 (which may be liquid-cooled) round the rotating cylinder 111. Only a narrow gap exists between the upper end of this cylinder and a stationary partition 71, forming a vacuum resistance in case of any slight air leakage at joint 61. The upper end of the apparatus comprises an oil-filled casing 82 containing the upper end of the cathode 4 and the high voltage connections thereto. Limited movement of the cathode is allowed by a tubular bellows 88 and also three centring rods, as at 85-86. The lower part 180, 181 of the casing surrounds the anode to form a cooling jacket and is closed by a diaphragm 15 corresponding to anode diaphragm 3. A structure passing through both diaphragms in a vacuum-tight manner terminates in a member 195 which supports diaphragm 3 against atmospheric pressure. Adjusting nuts on this structure enable the distance between the two diaphragms to be varied. As well as the anode, the outer casing is demountable in several sections, which bolt together round sealing rings. In a modification, Figs. 1 and 3 (not shown), the window-anode is part of a cylindrical rotating wall. If an outer cooling jacket is provided, the flow of cooling liquid can be utilized to drive the rotating anode by means of turbine blades.

Patent GB-732123-A (GB)
Title: A process for the preparation of condensation products from acetylene carbon monoxide and alcohols
IPC: C07C59/347
Filed: 1952-06-19
Abstract: Acetylene is reacted with an alcohol and carbon monoxide in the presence of a catalyst favouring the addition of carbon monoxide to an olefin, at a temperature below 120 DEG  C., preferably at 80-100 DEG  C., and at a pressure above 50 atmospheres, preferably 200-400 atmospheres, the partial pressure of the acetylene not exceeding 21 atmospheres, to form a mixture containing 3-40 per cent of an ester of 3-keto-pimelic acid, depending on the proportions of alcohol and acetylene present.  The reaction product also contains a mixture of various esters such as those of succinic acid, fumaric acid, maleic acid, and acrylic acid.  The acetylene is preferably dissolved in the alcohol which may be an alkyl or aralkyl alcohol and it is advantageous to employ as additional solvent the mixture of esters formed in the reaction and in cases where the reaction products are fractionated only the esters having a boiling point lower than that of the ketopimelic acid esters are used as additional solvent, no further alcohol being added.  The carbon monoxide is employed in excess with respect to the acetylene and the partial pressure of the carbon monoxide should preferably be at least 100 atmospheres. Specified catalysts are metals of the iron group or halides thereof and especially catalysts containing cobalt, or cobalt alone, e.g. in the form of Raney cobalt.  In examples (1) acetylene is dissolved in methanol containing Raney cobalt in an autoclave and carbon monoxide is introduced untl the pressure is 250 atmospheres.  The autoclave is then heated at 85 DEG  C. until no further absorption is observed at pressures higher than 200 atmospheres.  After cooling and removing the gaseous components more acetylene and carbon monoxide are introduced separately until the pressure is 200 atmospheres and the contents are again heated to 85 DEG  C. as before. These operations are repeated five times with the use of the residue of the previous operation as solvent in addition to the methanol still remaining. The products are then removed and fractionated to yield a fraction comprising the methyl ester of 3-ketopimelic acid; (2) as in (1) except that the carbon monoxide is introduced until the pressure is 200 atmospheres, the initial operation being repeated five times. Distillation of the reaction products yields a mixture containing the methyl esters of ketopimelic acid, of succinic acid, of fumaric acid and of maleic acid.

Title: Process for the manufacture of 2, 4-dioxo-3, 3-dialkyl-tetrahydro-pyridine-6-carboxylic acid esters or the corresponding free acids
IPC: C07D213/79
Filed: 1938-05-26
Abstract: 2 : 4-Dioxo-3 : 3-dialkyl-tetrahydropyridine-6-carboxylic acid esters are prepared by treating 2 : 2-dialkyl-3-oxo-5-aminohexene-4-dicarboxylic acid-1 : 6-dialkyl esters with alkali alcoholates.  The latter esters are obtained by condensing oxalic acid esters with dialkyl-acetoacetic acid esters and reacting with ammonia upon the resulting 2 : 2-dialkyl-3 : 5-dioxo-hexane-1 : 6-dicarboxylic acid esters.  The tetrahydropyridine-carboxylic esters may be saponified to the acids, from which, by decarboxylation, the soporifics described in Specification 457,012 may be obtained.  According to the examples: (1) oxalic acid diethyl ester is condensed with diethylacetoacetic acid ethyl ester in toluene in the presence of sodium, and the 2 : 2 - diethyl - 3 : 5 - dioxo - hexane - 1 : 6-dicarboxylic acid diethyl ester so formed heated with ammonia in methyl alcohol to form the ammonium salt, which is then dehydrated under reduced pressure to give 2 : 2-diethyl-3-oxo-5-aminohexene-4-dicarboxylic acid - 1 : 6-diethyl ester; by boiling the latter with sodium methoxide, ring closure takes place with formation of 2 : 4 - dioxo -3 : 3 - diethyl - tetrahydropyridine-6-carboxylic acid methyl ester, which is then saponified with caustic soda; (2) similar products are obtained from diallyl- and di-n-propyl-acetoacetic acid ethyl esters using sodium ethoxide for effecting ring closure.  The preparation of 2 : 4-dioxo-3 : 3-dimethyl-tetrahydropyridine-6-carboxylic acid and its esters is excluded.
