Patent GB-502665-A (GB)
Title: Manufacture of compounds containing active methylene groups
IPC: G03C7/36
Filed: 1937-08-19
Abstract: 502,665. Photographic materials. GROVES, W. W. (I. G. Farbenindustrie Akt.-Ges.) Aug. 19, 1937, No. 22746. [Class 98 (ii)] [Also in Group IV] A sodium malonic ester is condensed with a carboxylic acid chloride having an aliphatic chain of at least ten carbon atoms, and the acylmalonic ester so obtained is condensed with a hydrazine, a hydroxylamine or a primary aromatic amine to yield a pyrazolone, an isoxazolone or an acylacetic acid derivative having, at the carbon atom adjacent to the reactive methylene group, a substituent containing a carbon, chain of at least'nine carbon atoms. The products containing reactive methylene groups are useful in.colour-photography proceases in which a dyestuff is produced by colour development, by azo-coupling or by oxidation; photographic silver-halide emulsions containing these products may be used for preparing single-layer photographic materials or one or more layers of multi-layer materials In the examples : (1) sodium diethyl malonate is heated with stearic acid chloride, and the solution of diethyl stearylmalonate so obtained is heated with phenylhydrazine-3-carboxylic acid; 1-(3<1>-carboxyphenyl)-3-heptadecyl-5-pyrazolone is obtained; (2) diethyl stearylmalonate, obtained as in example 1, is heated with phenylhydrazine-4-sulphonic acid or (example 3) with phenylhydrazine-3-sulphonic acid to yield 1-(41- or 3<1>-sulphophenyl)-3- heptadecyl-5-pyrazolone; (4) diethyl laurylmalonate; produced from sodium diethylmalonate and lauric acid chloride, is heated with phenylhydrazine-3-carboxylic acid to yield 1-(3<1>-carboxyphenyl)-3-undecyl-5-pyrazolone ; (5) sodium diethyl undecanoylmalonate, .produced from sodium diethylmalonate and undecanic acid chloride, is heated with hydroxylamine to yield a decylisoxazolone ; (6) diethyl stearylmalonate is heated with paminobenzoic acid to yield a product believed to be stearylacetanilide-p-carboxylic acid. Other carboxylic acid chlorides which may be condensed with sodium diethylmalonate are those of undecylenic, palmitic, oleic, ricinoleic, 1-octodecylphenyl-4-carboxylic and 1-dodecylphenyl-4-carboxylic acids. Reference is made also to the use of the products of examples 1 and 2 in colour photography by dissolving the products in dilute caustic soda solution and methanol, and mixing the solution with a silver halide emulsion; an exposed layer prepared from the emulsion may be subjected to colour development with diethyl-p-phonylenediamine to produce a purple-red picture.

Title: Process for the production of artificial fibres of regenerated zein
Inventor: LIS LEON CHARLES
Filed: 1955-08-08
Abstract: Artificial fibres comprised of regenerated zein which has been spun by a one-bath process as described in U.S.A.  Specification 2,478,248, from an aqueous zein solution containing formaldehyde, to form fibres which, in the form of tow, have optionally been precured by allowing the tow to remain, while still wet with coagulating solution, for 1/2 to 3 hours in a chamber containing air of high humidity and at 80-100 DEG  F., are treated by stretching the tow by 50 to 300 per cent or more, impregnating it while still under tension with a solution containing 3-10 per cent of sulphuric acid, 3-10 per cent formaldehyde and at least 90 per cent saturated with sodium chloride, at 110-140 DEG  F., and then relaxing the tension, maintaining the tow at a temperature of 110-140 DEG  F. for 1/2 to 2 hours in a chamber containing air having a humidity of at least 90 per cent and washing the tow and thereafter, if desired, drying the tow and baking it at an elevated temperature, e.g. 300 DEG  F.  In the example, a tow of regenerated fibres prepared as described in U.S.A.  Specification 2,478,248 up to the washing and stretching stages, is passed, while being maintained under sufficient tension to maintain the stretch, back and forth between two rollers dipping into an aqueous saturated sodium chloride solution containing 3.5 per cent by weight formaldehyde and 5.0 per cent by weight sulphuric acid. The tow is then mangled to 100 per cent solution retention, the tension on the tow relieved, and the tow passed through a chamber of air at 120 DEG  F. and 100 per cent R.H for a residence time of 2 hours. The tow is finally washed for 27 minutes in water at 80 DEG  F., dried at 150 DEG  F. for 60 minutes and baked at 300 DEG  F. for 60 minutes.

Title: Improvements in dump vehicles for road and rail use
IPC: B60P1/16
Filed: 1927-08-31
Abstract: 288,890. Flowers, H. F. Aug. 31, 1927. Tipping wagons are constructed to tip to either side about trunnions arranged laterally to the longitudinal axis of the wagon by the operation of one or more power units also laterally spaced from the longitudinal axis and located substantially co-axial with the body trunnions. As shown applied to railway wagons the underframe comprises a central beam 13, Figs. 3 and 5, mounted on the vehicle bogies or trucks which beam carries rigid cross beams 14 and straddle plates 29<b>. The cylinder units C, C<a> on either side are trunnioned in the straddle plates and the body is pivoted to the underframe on pivots 22 in alignment with the trunnions 30, 30a, 31, 31<a>. The body comprises a floor bent downwardly at the sides as shown and doors 27, 27<a> adapted to be opened automatically as the body tips. Levers are pivoted to the underframe and are connected to the doors 27, 27<a> by links 25, 25<a> which are adapted to open and keep closed the doors as shown according to which side the wagon is tipped. The cylinder units comprise an outer cylinder 100, Fig. 7, an inner telescoping cylinder 105 and a piston 114 and piston rod 117 connected to the body by pin 121. Air is admitted through the hollow trunnions 101 to operate the cylinder 105 and piston 114. The piston rod 117 is hollow and provided with two series of apertures 150, 151 whereby as the piston traverses the cylinder 105 the air within the cylinder 105 escapes to the atmosphere until the apertures become blocked by the cylinder head causing a cushion of air within the cylinder to bring the operation of the cylinder unit to rest gradually at the limit of tipping. In modifications the apertures 151 are omitted and the interior of the piston rod 117 or of the cylinder is placed in communication with the atmosphere or a closed air container through a valve. Fig. 10 shows diagrammatically the various pipe lines for operating the tipping of the vehicles. The line 208 runs throughout the train and is used to charge the reservoirs 214 of each wagon through pipe 211 and valve 213, the pipe 208 being fed from the locomotive or through pipe 206 and valve 206<a> from the air brake pipe line 200. Pipe 215 connects the reservoir to an automatic valve V which is connected to a three-way valve 216 which controls the admission of fluid pressure to the cylinder units C, Ca. The valve V is operated by increased pressure from the reservoirs through valve 223 to line 218 and pipe 221, Figs. 10 and 17. The pistons 253, 255 ate forced upwardly closing port 256 open to the atmosphere and eventually opening valve head 250 putting in communication lines 215, 215a. Pressure is therefore available for the appropriate cylinder units when the three-way valve 216 is operated by shaft 230 and rod 229.

Abstract: 1287563 Valves KEELAVITE HYDRAULICS Ltd 12 Sept 1969 [26 June 1968 23 July 1968 5 May 1969] 30522/68 35043/68 and 22817/69 Heading F2V In a pressure regulator, flow from an inlet 4 to an outlet 4a takes place through a variable orifice defined by an adjustable plate 23 carried on the crown 8 of a piston 9, through a series of piston-controlled radial bores 13, through an annular chamber 14, and finally through a further series of radial bores 15, the piston being biased by a spring 7 in a direction so as to uncover ports 13 and to abut a circlip 6. The piston crown and the adjustable plate are formed with one or more circular orifices (Figs. 3, not shown) which can be made to co-operate with one another to variable extents to so define the flow path through the piston crown. Alternatively (Figs. 4 to 7, not shown), the piston crown may have a pear-shaped orifice with which either a helical or a circular and eccentrically mounted non-apertured plate cooperates, or the piston crown may be formed with circular apertures and the plate made rectangular with V-shaped notches in either its long or short sides, the plate being rotatable or displaceable parallel to its longest axis to so vary the degree of overlap of the notches and apertures. In a modification (Figs. 8 and 9, not shown), the valve inlet and outlet are both disposed transversely to the longitudinal axis of the valve body with the inlet leading to a space the opposite sides of which are defined by the piston crown and the adjustable orifice defining members. In a further modification (Figs. 10 to 12, not shown) the inlet flow is intersected by a fixed orificed plate across which is movable a second plate having a V-shaped or circular orifice with flow from upstream of the plates being channelled to the piston crown and the piston spring extending between the orificed plate and this crown.

Title: Improvements in or relating to processes for the manufacture of gases containing hydrogen by a conversion of hydrocarbons
IPC: C01B3/46
Filed: 1952-09-12
Abstract: <PICT:0772787/III/1> In the production of gases containing hydrogen by catalytic conversion of liquid or gaseous hydrocarbon with steam in successive cycles each consisting of a heating phase and a conversion phase separated from each other by steam scavenging, a layer of catalyst is positioned on a gas and liquid permeable support, the hydrocarbon and steam conversion mixture, the hot combustion gases for heating in the heating phase, and the steam for scavenging, are passed into contact with the catalyst, and the hydrogen-containing gases, combustion gases, and steam, during the respective conversion, heating, and steaming phases are withdrawn through the catalyst.  Liquid hydrocarbon and some steam is dispersed through injector 2 from pipe 1 and the remainder of the steam is introduced through pipe 3.  The mixture passes through catalyst layer 4 on perforated plate 5, and consisting of 4 per cent or less nickel deposited on rounded grains of e.g. magnesium or chromium oxide, which layer may be 400 mm thick, and the hydrogen-containing gases are withdrawn at 6.  The heating burner gases and steam purge are also introduced at 3 and withdrawn at 6 alternately with the conversion gases.  The conversion phase may be preceded by a reduction period when recycled product gas is introduced at 3 to reduce any nickel oxide to nickel and this reduction may include vaporization of an aqueous solution of an nickel salt, e.g. formate or nitrate, to deposit finely divided nickel in situ.  The vaporization of a nickel salt solution may alternatively be effected during the conversion phase.  In Figs. 2, 4 (not shown), gaseous hydrocarbon is introduced through vertical tuyeres or removable horizontal perforated tubes, covered with perforated bricks, situated in the base of the catalyst layer, the heating burner gases and steam on one hand and the conversion gases on the other, flow countercurrent, and combined provision for introducing both liquid and gaseous hydrocarbon may be made.  Specification 772,788 is referred to.

Title: Improvements in or relating to electric signalling systems
IPC: H04R3/00
Filed: 1939-08-09
Abstract: 533,360. Public address systems. STANDARD TELEPHONES & CABLES, Ltd., MEERS, R. A., and COCKBAIN, E. R. Aug. 9, 1939, No. 22981. [Class 40 (iv)] A public address sytem comprises a common amplifier MXC and a number of microphones AM ... CM which are normally blocked by networks AP 1  ... CP 1  to prevent howling. When one of them is spoken into, however, the corresponding network is brought to its low attenuation condition and at the same time the associated ones of networks AP  2  ... CP  2 , A.P 3  ... CP are brought to the high attenuation condition to prevent any other microphones being made effective, the control path from any microphone including one of these networks for each of the others. Details of the control circuit are shown in Fig. 2. Speech currents after passing an adjustable network for varying the'sensitivity of the device are amplified in a pentode valve V 1  and rectified in a voltage doubler system X 3 , X 4  and applied as bias to a valve V  2 . Condensers C 1 , C 2  and a resistance R 1  are arranged to cause the bias to build up rapidly when signals are received but to die away slowly when they cease. The valve V  2  and resistances R 5 , R 6 , R 7 , R 8  form a bridge across a diagonal of which the attenuating networks are connected, the arrangement being such that the direction of current through the networks is reversed when V 2  is biased back by speech signals. To limit the effect of strong signals, the input transformer is given a tertiary winding connected to a rectifier network X which normally has a high impedance but changes to the low impedance condition when the voltage derived by rectifying a portion of the signal in the anode circuit of V 1  exceeds the normal bias applied to the network X 1  from a resistance R 4 .

Title: Recording, translating and retrieving of intelligence
Filed: 1964-06-04
Abstract: 1,008,699. Electric digital date-storage; statistical apparatus; recording, reproducing and retrieving information signals. D. C. PRINCE. June 4, 1964, No. 23157/64. Headings G4C, G4M and G5R. Apparatus for translating and storing information includes a plurality of transducing heads 4 each scanning a continuous group of information, e.g. one line of a document 1, simultaneously with the other heads, a plurality of recording transducers 11 connected in a (1-1) relationship with the heads 4 and positioned in consecutive arrangement along a record medium 15 to simultaneously record the information of each group on to consecutive segments along the medium 15. The pick-up heads 4 are carried by a bar 8 there being one pick-up head for each line of information on the document 1. Each head 4 is electrically connected to one of the series of recording transducing heads 11 past which a magnetic tape 15 is pulled. As the bar 8 is moved across the document 1, the tape 15 is pulled past the heads 11 and so the information from the document is transcribed on to the tape. While the document is being replaced by another the tape is wound on to a spool 17. The information may later be reproduced on to another document by means of similar apparatus acting in reverse or may be transmitted over a distance, e.g. by telephone line before being reproduced. The tape 15 may be run much faster through the transmitting device than through the recording apparatus. If transmission takes place during the period in which the document 1 is being replaced, it may be at a slower rate, thus using a narrow band-width of the communication channel. The document 1 may be a punched card, the heads 4 then being electro-mechanical or electro-optical. It may also be a sheet on which characters are printed or typed, possibly having a magnetic code for each letter. An amplifier or code-changing device may be interposed between the heads 4 and 11 and if the heads 4 are electro-optical, a group of images may be stored to be compared with the optical image. The magnetic tape may be replaced by magnetic wire or a paper tape on which visible signals are printed together with a magnetic code. If the information is transmitted over a distance it may be transferred to a magnetic tape or wire or punched tape. This is then passed through a device similar to that shown in Fig. 2 and the information is rendered legible by a device similar to that of Fig. 1, the pick-up heads being replaced by punches or teletypewriter devices. In another modification the bar 8 may be fixed and the document 1 run underneath it on an endless belt.
