Title: Manufacture of highly polymeric polymethylene terephthalates
Inventor: HIRSH BENJAMIN WOOLF
IPC: C08K3/04
Filed: 1956-01-27
Abstract: Black fibre-forming polymethylene terephthalates are made by reacting crude terephthalic acid or a functional derivative thereof with a glycol of formula HO(CH2)nOH, where n = 2 - 10, in the presence of carbon black.  Crude terephthalic acid p  or functional derivative thereof is defined as "terephthalic acid or functional derivative thereof such as would yield, in the absence of the pigment, a polyester of no commercial value because of decomposition."  In examples, crude terephthalic acid is heated in an agitated autoclave at 240-260 DEG  C. at a maximum pressure of 50 lbs./sq. inch and after lowering the pressure a slurry of carbon black in ethylene glycol together with zinc acetate and antimony oxide is added. Polycondensation is then effected at 275 DEG  C. and 0.3 mm. of Hg pressure.  The crude terephthalic acid is prepared (1) by nitric acid oxidation of p-xylene (Specification 655,074), (2) by air oxidation of p-xylene (Specification 833,438), (3) by a carboxylate transfer reaction (Specification 747,204), or (4) by oxidation of mixed xylenes (U.S.A.

Title: Improvements relating to multi-press machines having air operated presses
IPC: A43D25/06
Filed: 1936-01-31
Abstract: 459,818. Boot - making machines. COMPO SHOE MACHINERY CORPORATION, 565, 5th Avenue, New York, U.S.A. Jan. 31, 1936, No. 2958. Convention date, Jan. 31, 1935. [Class 17 (i)] Sole-laying.-In a machine of the kind in which a number of inflatable presses on an endless belt are intermittently moved, the work being changed at an operator's station, each press is automatically deflated while at rest prior to reaching the operator. Each press has an inflating and deflating valve of the kind having a projecting pin, pressure on which deflates the press, and at a position on the conveyer frame which each press reaches before reaching the operator, a spring-pressed bar, preferably engaging the pins of two consecutive presses, is released to press on the pins. Electrical and pneumatic means are described for releasing the bar. Beyond the operator's station, for re-inflating the press wherein a new workpiece has been positioned, a nozzle 18 is brought up to the valve on depression of a treadle, as in prior machines. The nozzle is slidable transversely of the conveyer in a carriage slidable longitudinally of the conveyer, and urged to normal position by a spring 21. As the press moves away from the operator's position an arm 22 thereon engages an arm 23 on the carriage when the valve and nozzle are in line, the carriage thereafter moving with the press until the conveyer comes to a drift stop. This movement of the carriage allows an arm 24 of an electric switch to open the switch releasing the plunger 30 of a solenoid to the action of a spring 32, the plunger carrying a bar 29 engaging the pins of the valves of the two consecutive presses next to reach the operator's position. Fig. 2 shows a suitable electric circuit, 33 being the main switch closed by the operator after work changing to cause the conveyer to advance the presses one step, M the motor driving the conveyer, 38 and 39 the electric terminals, and 42 a magnetic switch having conductors 43, 45, 50 connecting contacts shown when the coil 41 is closing the switch 33. The solenoid 31 is energized by the closing of this switch and remains energized after the opening of the same until the switch 24 also is opened. To allow the arm 22 to pass the arm 23 the latter is raised by a fixed cam. In a modification, the solenoid is de-energized by a photo-electric cell 57, Fig. 7, when light thereon from a lamp 55 is obstructed by the passage of a press 13. The generator G energizes the solenoid so long as the magnetic switch 62 is closed by current from an amplifier 64 in the circuit of the cell. In another modification, a pneumatic piston is substituted for the solenoid, a " bleeder " aperture in the cylinder allowing the piston to return comparatively slowly.

Title: A process for the acylation of amino acids
IPC: A61K31/195
Filed: 1966-01-25
Abstract: N-Acylamino acids are prepared by reacting an amino acid, having at least one primary or secondary amino group, with a carboxylic acid chloride at an alkaline pH and in the presence of, at the start of the reaction, at least 5% (on weight of reaction mixture) of a free chloride or chlorides which is one or more of phosphorus trichloride, phosphorous pentachloride, phosphorus oxychloride, sulphonyl chloride or thionyl chloride.  The process is applicable to a -amino carboxylic acids and may also be used for the acylation of other amino carboxylic acids, e.g. those containing, as additional substituents, amino, uinino, hydroxyl, carboxyl or thioalkyl groups, and for the acylation of amino sulphonic acid, e.g. taurine.  The preferred acid chlorides are those derived from the saturated and unsaturated C10- 12 carboxylic acids.  The amount of inorganic halide present in the reaction mixture is preferably no more than 15% by weight of reaction mixture.  The acid chloride may be made by chlorinating the acid with one of the specified inorganic chlorides and the resulting reaction mixture containing unreacted inorganic halide used directly in the present process.  Examples relate to N-lauryl-, N-stearyl-, N-cocoyl- and N-oleyl-sarcosines.

Title: Improvements in or relating to electrical methods of and apparatus for determining the thickness of metal coatings
IPC: G01B7/06
Filed: 1944-02-24
Abstract: 579,202. Determining dimensions of materials. ARMOUR RESEARCH FOUNDATION. Feb. 24, 1944, No.. 3460. Convention date, Sept. 25, 1943. [Class 37] Apparatus for determining the thickness of metal coatings on foundations of dissimilar metals or alloys or of a non-metallic character includes means defining a chamber for an electrolyte in confined contact with the coating to be measured and an electrode forming with the coating and electrolyte a cell for generating an electric current in the chamber to effect the anodic dissolution of the metal of the coating. The coating 12 whose thickness is to be measured is formed on a base or foundation metal 11. A cylindrical metal member 14 rests on the coating 12, making electrical contact therewith, and is formed with a cylindrical axial cavity 15 restricted at its upper end by an inturned annular shoulder 16. Within the cavity is positioned a composite insulating and sealing member 17 comprising a cylinder 18 of plastic material, rubber &c. in the lower end of which is a sealing washer or gasket 19 which extends beyond the lower edge of the cylinder 18 to rest upon the coating 12. The washer 19 also extends into the cylinder 18 to provide an annular shoulder against which rests the lower end of a hollow electrode 22, which is thus insulated from the coating 12. A spring 23 engaging the shoulder 16 presses the washer 19 into sealing contact with the coating 12. The electrode 22 is partly filled with an electrolyte, which makes contact with the coating 12 over the area exposed by the aperture in the washer 19. The cell so formed is connected by leads 28, 30 in series with a switch, milliammeter, and rheostat. The switch is closed and a stopwatch started, the current drawn from the cell being maintained at a predetermined value. The endpoint, or the removal of all the coating metal, is indicated when the current changes rapidly and can no longer be maintained constant by the rheostat. At this point the stopwatch is stopped and the switch opened, the time taken being a measure of the thickness or weight of the coating. The electrolyte may be a 10 per cent. solution of sodium hydroxide and the cathode may be brass or copper coated with a tarnish film. To increase the constancy of the current a small quantity of an oxidizing agent such as hydrogen peroxide or sodium hypochloride may be added to the electrolyte.
