Abstract: 1382932 Testing bottles H E SCRIBNER 15 Feb 1973 7463/73 Headings G1M G1S A device for testing the tops of bottles for flaws, chips, cracks, irregularities and other defects comprises a conveyor 38 for carrying the bottles past an inspection point, a rotatable support 10, a plurality of air actuators 43 carried by the support, and a plurality of sensor heads 50 carried by the actuators, each actuator and sensor head being supplied with pressurized air . as it passes the inspection point. The support 10 comprises a pair of serrated wheels 26, 28 and may be driven by the bottles on the conveyor 38, or independently driven. Each air actuator 43 is connected via pipe 64 to a corresponding port in manifold 63, the port registering with fixed air port 68 as the actuator passes the inspection point to supply air to the actuator and move the sensor head into engagement with a bottle top. Each sensor head is made of resilient rubber and includes a recess 54 for engaging about the top edge of the bottle. The recess 54 in each sensor head is connected via pipe 120 to a corresponding port in a manifold 112, and air is supplied to the recess when the port registers with a fixed port 125 Fig. 3 (not shown) in a fixed valve core 102. A fluidics circuit Fig. 4 is supplied which rejects a defective bottle from the conveyor at a point displaced from the inspection point. Pressure is applied to each sensor head via regulator 206 and according to whether a bottle is sound or defective, valve 210 will or will not be triggered to produce or not produce an output pressure. This pressure or no pressure signal is stored in flip flop G1, G2 and as the passage of successive bottles is detected by detector 214, the pressure or no pressure signal progresses from flip flop G1, G2, through flip flop G3, G4 and shift registers SR1, SR2 to shift register SR3. When the pressure no pressure signal is in shift register SR3, and another bottle is detected at the inspection point by detector 212, the bottle to which the signal corresponds is opposite rejector 150 and is rejected or not rejected according to the signal.

In examples: 6-methoxy-8-[11 - methyl - 41 - ethylaminobutylamino]-, 6 - methoxy - 8 - [11 - methyl - 51 - isopropylaminopentylamino] -, 6 - methoxy - 8 - [41-ethyl-41-ethylaminobutylamino]-, 6-methoxy-8-[11 - methyl - 41 - isopropylaminobutylamino]-, 6 - methoxy - 8 - [11 - methyl - 41 - n - propylaminobutylamino] -, 6 - methoxy - 8 - [11-methyl - 41 - isobutylaminobutylamino]-, and 6 - methoxy - 8 - [11 - methyl - 41 - tert. : butylaminobutylamino] - quinolines are prepared.  The substituted quinolines may be converted into their salts, e.g. the hydrohalides, phosphates, oxalates or citrates.  Amines.-1 - Methyl - 4 - ethylaminobutylbromide hydrobromide may be prepared by reacting the sodium derivatives of acetoacetic ester with ethylene chloride, subjecting the resulting condensation product to ketonic hydrolysis to obtain 1-chloropentanone-4, to reduce the resulting ketone with aluminium isopropoxide to yield 1-chloropentanol-4, which is then reacted with ethylamine to yield 1-ethylaminopentanol-4, and on treatment with thionyl bromide gives 1-methyl-4-ethylaminobutylbromide hydrobromide.  Similarly 1-methyl - 4 - ethylamino -, 1 - methyl - 4 - n-propylamino -, 1 - methyl - 4 - isobutylamino-, and 1 - methyl - 4 - tert. - butylamino - butylbromide hydrobromides may be prepared.  Similarly 1 - methyl - 5 - isopropylaminopentylbromide hydrobromide is prepared from the sodium derivative of acetoacetic ester and trimethylene bromide. 4-Ethyl-4-ethylaminobutylbromide hydrobromide is prepared by reacting 3-methoxypropyl magnesium chloride with propionaldehyde to form 1-methoxyhexanol-3 which is then converted to 1-methoxy 3-chlorohexane by treatment with thionyl chloride, the resulting substituted hexane is reacted with ethylamine to give 1-methoxy-4-ethylaminohexane which is then refluxed with hydrobromic acid to yield 4-ethyl-4-ethylaminobutyl bromide hydrobromide.

Title: Improvements in or relating to ring rolling mills
Inventor: ASHTON NORMAN COUPE
IPC: B21H1/06
Filed: 1958-03-12
Abstract: 877,579. Rolling annular bodies. ASHTON, N. C. March 10, 1959 [March 12, 1958], No. 7885/58. Class 83 (4). In a method of forming a ring or cylinder from a blank on a ring rolling mill in which radial pressure is applied to the blank between an inner and an outer roll one of which is driven, a control member is located to engage the periphery of the blank along an axial line lying in a plane containing a tangent to the inner roll at the point where the inner roll engages with the blank so that the control roller does not move relative to the axis of the inner roll during rolling. A preheated ring 46 is reduced in thickness and expanded in diameter between a driven support roll 44 and a pressure roll 48 slidably mounted on a plate 54 attached to framing 12. In a modification the rolls may be vertically mounted and arranged on a table. During rolling the blank is supported and guided to maintain a circular form by freely rotatable rollers 92, 122 or alternatively by rods located to engage the periphery of the blank at points which remain on the external periphery of the blank throughout the rolling operation. There are said to be two such points each spaced at a distance from the point of contact of the inner roll 44 with the blank given by where A is the constant annular cross-section of the blank. Each guide roller is adjustable horizontally by the rotation of a threaded spindle 104, Fig. 6. which engages in a slidable sleeve 96 carrying the bearing block 94 for the guide roller. After adjustment the rollers may be locked in position by a device operated by a handle 113. The guide rollers may also be adjusted vertically and/or tilted to suit various sizes of blank. The support roll 44 is driven by an electric motor 16 through a reduction box 22. a clutch 24, 26 and a driven shaft 28. The downward movement of the pressure roll 48 during rolling is effected by an hydraulic ram 56 fed by a pump 62 and a reservoir 64, the pump being operated by a motor 66. The ram is supplied through a two-way control valve 70. A trip lever 80 pivoted on the framing 12 is connected through a rod 82 of adjustable length to a release valve so that the downward movement of the roll 48 may be limited to control the reduction in radial thickness of the ring. To prevent axial expansion of the blank flanged support or pressure rolls may be used or alternatively tapered rollers may engage the annular surfaces. Rings of arcuate radial crosssection may be rolled using the rolls of Fig. 4 (not shown). Tapering rings may be made by rolling a ring of cheveron-shaped radial crosssection and then halving it. The apparatus may be used for truing up rings without reducing the thickness.
