Title: Chemical and heat conversion of poly-amide-acids to polyimides
IPC: C08G73/10
Filed: 1967-03-22
Abstract: 1,135,544. Polyimides. E. I. DU PONT DE NEMOURS & CO. 22 March, 1967 [24 March, 1966], No. 13468/67. Heading C3R. A coating, fibre, foam or film-forming mixture comprises an organic solvent, a polyamide acid cyclizable to polyimide and an N-acyl azole compound having at least one 5-membered ring containing 2 to 4 N atoms and 2 double bonds. Of the azoles specified, imidazole is preferred. The azole compound and polyamideacid solution are admixed, usually at - 5‹ to 15‹ C., and the solution can then be extruded, spun, sprayed, blade coated or moulded, and the resulting article can be stored per se or heated to at least 75‹ C. to effect oyclization to the imide, the by-produced carboxylic acid being removed with the solvent. Fillers, abrasives, pigments &c. can be added prior to shaping. In a typical Example (1) N-acetyl imidazole was added at room temp. to a solution in N,N-dimethylacetamide of bis-(4-aminophenyl)-ether, polypyromellitamide-acid, and the resulting solution was cast into a film on a glass plate, dried at 120‹ C., stripped from the plate, and heated at 300‹ C. to yield a polyimide film.

IPC: H01H47/14
Abstract: 135,265. Igranic Electric Co., (Cutler- Hammer Manufacturing Co.). Nov. 15, 1918, Electro-magnetic switches.-In order to avoid the premature closing of an electro-magnetic lock-out switch, of the type having closing and holding-out coils 4, 5 operating on opposite ends of a centrally pivoted armature 1, during the first rush of current while the holding-out magnetic force is reaching its full holding-out value, the holding-out coil is shunted by a self-inductance or by a resistance having a negative temperature-coefficient, which further increases the pull of the holding-out magnet while the current is rising. Alternatively, the closing-winding may be shunted by a condenser, a non-inductive resistance, or a resistance having a positive temperature coefficient, which produces a lag in the building-up of the closing magnetization while the current is rising. Both coils may be shunted as described. The condenser or shunting resist. ances 14 are mounted on the base of the switch.

Title: Gauging and sorting apparatus
IPC: B07C5/12
Filed: 1955-05-13
Abstract: 769,166. Sorting devices. OWENS-ILLINOIS GLASS CO. May 13, 1955 [June 8, 1954], No. 13857/55. Class 106 (2). An apparatus for sorting articles 10 comprises a gauging station A through which the articles are passed, a control device at the station operable by an article having a dimension or shape out of conformity with a prescribed limit, and electroresponsive means controlled by the control device for separating such article from those whose dimensions conform to the limit. Bottles are passed on a travelling conveyer 12 between convergent guide rails 13, 14, being constrained to enter the gauging station edgewise by the rails and a roller 18. The rail 14 has an extension 19 carrying a switch comprising contacts 24 and a contact bar 23 held clear of the contacts by a spring 25 which also presses a gate 21, pivoted at 22, into contact with the side of a bottle 10. A bottle with a bulged side 26 causes the gate 21 to press the bar 23 against the contacts 24, energizing a solenoid 35 which moves a core 36 carrying a piston 37 to the left. A pipe 38 carries compressed air to the valve 34, which air, on movement of the piston 37 passes through a retarding device 43 which affects the timing to a valve 30. An arm 27, pivoted at 28 is swung into the path of the defective bottle and removes it as it passes from the gauging station A, the switch 23, 24 automatically opening on the passing of the bottle, thus permitting the arm 27 to retract. Two further embodiments are described, one to remove bottles with sunken sides, and one, Fig. -3, to remove bottles with either defect. In Fig. 3, the spring 25 holds the bar 23 between contacts 24, 24a. The circuit remains open until the neck 50 of a bottle causes a pivoted lever 46 to abut a contact 48, it being connected at the pivot 47 to the electrical supply, and until a defective bottle, disturbing the bar 23 from its equilibrium position closes the circuit, either by connecting contacts. 24, in the case of a bulging bottle, or 24a in the case of a sunken one.
