Title: Improvements in apparatus for conveying glassware into annealing leers
IPC: C03B35/06
Filed: 1924-02-04
Abstract: 233,402. Williams, P. Q. Feb. 4, 1924. Charges, conveying. - Relates to mechanism for moving ware from a bottle-making machine to an annealing leer, and comprises means controlled by the. movement of the ware for intermittently transferring it from the carrier to the leer. An endless conveyer 21, carried on a frame over sprockets 24 one of which is driven from a motor 33 on a platform 28 adjustable by a screw 30, comprises hinged plates 44 supported by rollers 41 tracking on longitudinal angle irons 38 mounted on opposite sides of the frame. The forward end of the conveyer frame is mounted on a support 49 about which the frame is oscillated by a pinion 72, driven from a motor 69 attached to a platform 68 and engaging a stationary rack 77 carried by a channel member 78 adjustably secured to the machine frame. The rear end of the frame 21 carries a pocket 223 with movable back-plates 240 and an ejector slide 239. Triggers 229 within the pocket are depressed by the ware and complete circuit, through a solenoid 237 actuating the plates 240 and the slide. Air is supplied through the support 49 to longitudinal chambers 55 terminating in horizontal nozzles 56 disposed along the side of the conveyer. Adjustable side-bars 61 guide the ware along the conveyer and carry deflectors 66 for moving the ware laterally. The platform 68 is secured to the rear end of the frame and is supported by rollers 79, engaging the channel 78. Lugs on the latter co-operate with the arm of a switch for reversing the motor 69. The leer conveyer 88 is actuated intermittently from an electromotor energized by the closing of contacts on the frame. A sliding door 102 provided with an opening 103 for the ware is arranged in front of the leer. In operation, ware is fed from a bottle making machine neck first to a device which turns, by means of shoots and an inclined block, panel bottles up on side with necks backwards or forwards .and delivers them to the conveyer 22. The air blast from the nozzles cools the bottles and rolls round bottles across the belt, while the deflectors 66 displace panel bottles to prevent them sticking. The ware is discharged to the pocket 223 whereupon the triggers 220 are depressed closing circuit through the solenoid 237. The armature of the latter is withdrawn from a lug 272 and a cam 244 is rotated by the motor 269 to actuate arms 242 for withdrawing the plates 240. and reciprocating the plate 239 for moving the ware through the opening 103. Specification 230,598 is referred to.

Title: Improvements in and relating to diesel hammers
Inventor: LANG ANTON
IPC: E02D7/12
Filed: 1958-01-29
Abstract: 850,349. Two-stroke engines. DORNFELD, R., and DORNFELD, E. Jan. 29, 1958, No. 2943/58. Class 7(2). [Also in Group XXVIII] A power hammer constructed and operating as a single cylinder two-stroke diesel engine comprises a hammer body 43 which is driven upwards during each expansion stroke and thereafter descends under its own weight thereby producing the next compression stroke during which air is compressed in a combustion chamber. The body 43 includes a cylinder head 17 which carries a combined fuel injector and fuel injection pump. A piston 1 exposed to the cylinder air pressure is slidably mounted in a member 13 carried by the head 17 movement being opposed by a spring 11. The injection nozzle 2 and the fuel injection pump cylinder 6 are mounted within the piston 1 and a plunger 25 carried by the head 17 is adjustably positioned within the cylinder 6 by means of a stop 27. Fuel carried within the body 43 passes via gaps 38, 55 and a filter 22 to the inlet port 40, air initially within the pump cylinder passing through ports 50, 53 and upwards into the head 43. Fuel is discharged from the pump cylinder through a filter tube 5 and non-return valves 3. The specification states that the weight of the piston 1 when descending with the head 17 assists the spring 11 in opposing the fuel injecting movement of the pump due to the compressed air in the cylinder whereby fuel injection is delayed to an extent depending on the kinetic energy acquired by the weight during the descent of the hammer body and consequently on the distance through which the hammer body has fallen. The compression ratio of the hammer may be altered by attaching air storage chambers to the hammer body which communicates with the cylinder by a duct 57,

Title: New anthraquinone-triazine monoazo dyestuffs and their manufacture and use
IPC: C09B62/08
Filed: 1957-01-28
Abstract: The invention comprises dyes of formula:  <FORM:0849115/IV (c)/1> where n is 1-3, R and R1 are benzene radicals, X is an amino bridge bound to R1 in m-position to the azo link, Y is a heterocyclic ketomethylene radical bound to the azo link in a position vicinal to a keto group, Z is SO3H or H and A is Hlg, NH2 or an organic radical not having the character of a dyestuff bound to the carbon atom directly or through an O or N bridge.  They are made by condensing, preferably at pH5-7, a di- or tri-halogen -1, 3, 5- triazine with appropriate azo and anthraquinone dyes and, if necessary, replacing a halogen atom of the triazine ring with an amino group or the desired organic radical.  Steps in the process may be effected in any order of succession.  Preferred are dyes of formula:  <FORM:0849115/IV (c)/2> where A is an alkyl or aryl radical of up to 12 carbon atoms and P2 is a 1-phenyl -3- methyl-5-pyrazolone radical bound in the 4-position to the azo link and the phenyl nucleus of which is #s-substituted.  Preferred starting anthraquinone dyes are those which contain in R an acylatable amino group, particularly an NH2 group pto the NH group.  The benzene nucleus may contain substituents such as methyl, ethyl, chlorine or sulphonic acid groups.  Representative of specified anthraquinone dyes are 1-amino -4-(41-aminophenylamino)-anthraquinone -2, 31- and -2, 5-di- and 2, 31, 8-tri-sulphonic acids, 1-amino -4-(31-aminophenylamino) -anthraquinone -2, 41-disulphonic acid, 1-amino -4- (31-amino- and 31-amino -61- methyl -phenylamino) -anthraquinone -2- sulphonic acid and 1 -amino -4-(41-aminophenylamino)-anthraquinone -31- sulphondiethylamido- and -methylsulphone -2-sulphonic acids. Indicated as azo dyes are those made by coupling barbituric acid or especially 5-pyrazolones with benzenic compounds which contain in a m-position to the diazo group a free amino group or a substituent convetible thereto.  Radical A may be derived from compounds such as ethanol, phenol, 4-sec-butylphenol, methylamine, diethylamine, aniline, N-methylaniline, cyclohexylamine, methoxyethylamine and ethanolamine.  The dyes are used on polyhydroxylated and nitrogenous textile materials e.g. polyvinyl alcohol, natural or regenerated cellulose, silk, leather, wool and superpoly-amide and -urethane fibres.  When the dyes have one or two SO3H groups they are especially suitable for dyeing nitrogeneous textiles from neutral or acid baths, and those containing more than two SO3H groups are especially suitable for cellulosic materials.  The latter dyes when containing a halotriazine residue may be fixed on the fibre by an alkaline treatment.  Examples and Tables are provided illustrating the preparation of the dyes and their use in dyeing wool and cellulose in green shades.  Specifications 466,886, 775,308 and 797,946 are referred to.

Patent GB-677218-A (GB)
Title: Recovery of dicyanoalkyl ethers and sulfides
Filed: 1951-02-09
Abstract: Bis-cyanoalkyl ethers and sulphides containing dissolved unsaturated compounds of low water solubility are recovered by mixing the solutions with water at about 70-100 DEG  C. in amount sufficient to dissolve the solvent, separating the water-solvent layer from the unsaturated compounds, cooling to give a water layer and a solvent layer, and separating the layers.  The solvents are used for separating unsaturated hydrocarbons from saturated, especially aromatics such as benzene, toluene and naphthalene from paraffins, monoalkyl phenols from polyalkyl, N-monoalkyl aromatic amines from N-polyalkyl, and N-alkyl aromatic amines from C-alkyl.  The alkyl groups in the solvent should contain not more than 6 C atoms for the solubility characteristics in water to be suitable for separation. The solutions may be extracted in batch or continuous operation, for example by counter-current-flow in a column at 80-90 DEG  C., the solution of solvent in water being cooled to about 25 DEG  C. and the layers formed continuously decanted, the water layer being recycled to the column and the solvent re-used for a further separation. Pressure may be above atmospheric.  The ratio of water to solvent may be 3 : 1 or above.  Examples describe the water extraction of solutions of naphthalene and toluene in bis-(2-cyanoethyl)-ether or sulphide, a ,b 1-dicyanodiethyl ether or bis-(b -cyanoisopropyl)-ether.

Abstract: 878,740. Automatic tape feed control systems. INTERNATIONAL BUSINESS MACHINES CORPORATION. Jan. 29, 1960 [May 1, 1959], No. 3306/60. Class 38 (4). In a tape-feeding system a free loop of tape is held in a column by suction and an independent panel in a wall of the column, experiencing a force, due to suction, dependent on the length of the loop, is supported by means with which strain gauges are associated to derive an electrical signal dependent on the length of the loop. In Fig. 1, a magnetic tape 29, fed past a magnetic transducer head 14 in one or other direction by a capstan 13 or 15, has loops held in close fitting vertical columns 11 and 16 by suction created by vacuum pumps 12 and 17. Plates 30 sealed by flexible members (not shown) to one side of the columns are attached to supports 31 and 32, the forces on which are thus dependent on the lengths of the loops. Strain gauges such as 41C, 40C associated with these supports are connected in bridge circuits the outputs of which serve to control motors 20, 21 driving the supply and take-up reels 9, 19 to maintain constant lengths of loop in the columns. In a modification, steel strips running vertically down the sides of the columns are flexed to different extents according to the lengths of the loops and apply forces to cantilevers with which strain gauges are associated to produce signals representative of the lengths of the loops.
