Title: Improvements relating to valves for air compressors
IPC: F04B39/10
Filed: 1936-04-02
Abstract: 472,697. Air compressors. CLIMAX ROCK-DRILL & ENGINEERING WORKS, Ltd., and WINHAM, H. W. April 2, 1936, No. 9798. [Class 8 (i)] In a reciprocating air - compressor the delivery ports 12 are arranged near the periphery of a cylinder cover 3 larger than the cylinder bore and are inclined so that their inner openings lie wholly or partly on the end part of the cylindrical wall of the cylinder. This arrangement makes nearly the whole of the area within the cylinder bore available for the intake ports 8. The cylinder cover 5 is formed with guards or cages for the valves and further with cooling ribs. The whole is surmounted by a retainer 25 likewise provided with cooling ribs and secured to the cylinder by the bolts 27. The retainer bears on the periphery of the bore and so minimizes bending stresses. In a modification, the retainer is arranged for water-cooling.

Title: Production of yellow dye images by color development
IPC: G03C7/32
Filed: 1959-03-20
Abstract: Compounds of the general formula:  <FORM:0865032/IV (b)/1> wherein R is hydrogen, halogen, nitro, alkoxy, alkyl or -NHR1 where R1 is alkyl or carboxylic acyl, are prepared by acylating 5-acetamido-2-naphthol with the appropriate benzoyl halide in the presence of aluminium chloride, and then hydrolyzing the acetamido group to the free amine with acid or alkali.  Examples are given of the reaction of 5-acetamido-2-naphthol with benzoyl chloride, 2-chloro-benzoyl chloride, 4-methyl-benzoyl chloride or 3-nitro-benzoyl chloride and of the hydrolysis of the products to the free amines. Alternatively, the 5-acetamido intermediates may be prepared by a Fries rearrangement of the benzoic acid esters of 5-acetamido-2-naphthols. Thus, 5-acetamido-1-p-methoxybenzoyl - 2 - naphthol is prepared by refluxing 5-acetamido-2-naphthyl-p-methoxybenzoate with aluminium chloride in tetrachloro-ethane.  The product may be hydrolyzed to the corresponding 5-amine.  5-acetamido-2-naphthyl-p-methoxybenzoate is prepared by adding anhydrous, aluminium chloride powder to an ice-cold mixture of 5-acetamido-2-naphthol and p-methoxy benzoyl chloride in tetrachloro-ethane.  Alternatively, it is suggested that such esters could be made by a Schotten-Baumann reaction using a benzoyl chloride, the naphthol and sodium hydroxide. Specification 640,382 and U.S.A.  Specification 2,486,440 are referred to.

Patent GB-788276-A (GB)
Title: A process for the purification of phthalic acids
IPC: C07C51/487
Filed: 1956-03-29
Abstract: Phthalic acids are purified by treating the salt of the phthalic acid with an adsorbent material or an ion exchanger. Suitable salts are those of alkali metals or ammonia, and suitable adsorbents are e.g. active carbon or activated aluminium hydroxide.  The crude acids purified may be those which have been prepared by the oxidation of a dialkyl benzene with an oxygen containing gas in the presence of a heavy metal compound, e.g. cobalt and manganese acetate, as catalyst, and which have been washed one or more times with water.  Crude acid so obtained is treated with an aqueous solution of a base, the amount of base being equivalent stoichiometrically to the amount of phthalic acid in the crude acid.  After the treatment of the phthalate solution with the adsorbent or the ion exchanger the solution is separated therefrom.  If an adsorbent is used this is separated by filtration, while when an ion exchanger is used the purification may be carried out continuously by passing the solution through a column filled with the ion exchanger, a clear liquid being immediately drawn off.  The phthalate may then be crystallized, separated from the solution and dissolved again in water, after which the phthalic acid is recovered e.g. by acidifying the phthalate solution preferably with the exact amount of acid required, or by hydrolytic decomposition, or by thermal decomposition.  Specification 767,463 is referred to.

Abstract: 521,533. Diaphragm pumps. McMECHAN, M. H. March 30, 1939, No. 9996. [Class 102 (i)] [Also in Group XIII] A pump actuated by gas evaporated from solidified CO 2  and employed to circulate brine or other liquid cooled by the solid refrigerant comprises a flexible diaphragm 62 acted on by a spring 69 and carrying a curved abutment arm 67. Under gas pressure the diaphragm is forced to the left against the action of the spring. a flap valve 58 closes the brine inlet port 56 and the brine is discharged through a non-return valve 59. The arm 67 rocks a lever 76 to open a ball or other gas outlet valve 72 at the end of the stroke of the diaphragm, and on the return stroke the spring 69 forces the diaphragm to the right and a bolt 6<SP>5</SP> rocks the lever 76 to close the valve 72 under snap action of springs 85. A vent valve in the gas supply conduit is opened to stop the pump when a low temperature is reached in the cooling chamber. The refrigerant container, however, may be maintained under pressure ready for delivery of pressure vapour when the vent valve is closed. In a modification the pump produces an oscillating movement of the brine.

Title: A moired floor covering and a process for its manufacture
Inventor: GRAAB GERHARD
IPC: B29C43/34
Filed: 1997-06-26
Abstract: A rubber moir+E,acu e+EE  floor covering is disclosed. The covering is produced by continuously feeding a screw-type short extruding machine having a length/diameter ratio of 6:1 with two or three varicolored strips of vulcanizable elastomeric material. The operating temperature is between 60 DEG  C. to 100 DEG  C. The elastomeric material leaves the extruder via a perforated disk having 200 to 600 cylindrical bore holes 3-5 mm in diameter. Each of the resulting strands is severed to produce segments that are 1 to 2 mm thick, the formed pieces are then cooled off on a section 4 meters to 6 meters long. Subsequently, the formed pieces are allowed to fall into the roll nip of a temperature controllable two-bowl calendar. The web of material leaving the calendar is fed to a continuous vulcanization installation and leaves it as finished floor covering. The material throughput rate in this continuous process may be varied from 700 kg/h up to 1300 kg/h.

Filed: 1990-01-09
Abstract: PURPOSE:To expand compressed image data fast by providing a process proce dure which compresses and transmits or records still image data, and expands the compressed image data in the form of hardware. CONSTITUTION:The input compressed data are decoded by storage means 10 and 20 stored with a DC Hofmann table and an AC Hofmann table into bit- quantity data on a DC component and bit-quantity data and continuous-zero- quantity data on an AC component. Data detecting means 11 and 21 extract effective data on the specified number of bits. A difference encoding means 13 adds the DC component of a last block and decodes the sum and a zero-data adding means 23 adds zero data to the effective data on the AC component and decodes the data into a linear series of specific order. Then a multiplying means 3 multiplies the decoded data by respective threshold values of a quantaization matrix and quantizes the data reversely and the reverse quantized data are stored temporarily in buffer memories 6a and 6b and outputted after reverse discrete cosine conversion. Consequently, a still image is expanded fast by the hardware.

When the outer layer is formed thinner, its fact burning characteristic is close to that of W wire. The electric resistance heating wire is not broken due to oxidation, for a long time, because of the resistance to oxidation characteristic of the Fe-Cr-Al outer layer. When Al or SiO2 layer is provided thereon, resistance to oxidation is further improved.
